Technical Field

The subject matter of the present invention generally relates to an assembly machine. More particularly, the subject matter relates to a dispensing head or pick-and-place head, a spindle and a nozzle for a pick-and-place machine.

Background

The assembly machines comprise complex robots with a dispensing head moving along one or more axes for assembling the unfinished product. The dispensing head can be used to pick, place, supply material to a component or surface, manipulate, screw, or otherwise dispense a task or material. In pick-and-place assembly machines, for example, the dispensing head is typically configured to receive a plurality of different spindle and nozzle assemblies to efficiently pick, place, and assemble the various components. The dispensing head must typically include a spindle assembly for imparting rotation to the nozzle and also have the ability to move the nozzle along the Z-axis. These requirements result in the dispensing head of the pick and place machine being generally large and heavy.

Furthermore, the assembly machine may comprise a multi-spindle or multi-nozzle dispensing head. These dispensing heads may be configured to pick up multiple components, for example from one or more feeder magazines, and then move to a placement location to place the multiple components. This reduces assembly time compared to having a single spindle or a single nozzle. This is because a single spindle and nozzle arrangement typically needs to be moved back and forth between the feeder garage and the placement position with a single placed component. However, providing additional spindles and nozzle receptacles on the dispensing head generally increases the size, volume, and engineering complexity of the head. Furthermore, if one spindle or nozzle breaks down or begins to function improperly, the entire dispense head may be damaged until the problem is resolved.

In addition, the dispensing heads currently used in pick and place systems are typically controlled by a machine-level processor or control system. These systems eliminate the possibility of creating an independent motion control configuration for each individual spindle on a multi-spindle dispense head. Specifically, a motion control configuration at the dispense head level is created.

Accordingly, improved assembly machines, dispense heads, spindles, spindle mounting modules, and spindle magazines that alleviate or reduce one or more of the above limitations would be welcomed in the art.

The embodiments of the disclosed apparatus and method described below are described in detail herein by way of example and not limitation with reference to the figures.

Referring to fig. 1, an assembly machine 10 is shown. In the illustrated embodiment, the assembly machine 10 is a pick and place machine configured to assemble a Printed Circuit Board (PCB). For example, the assembly machine may be an advanced package assembly machine, a part assembly machine, or the like. In other embodiments, the features described below can be applied to various other assembly machines, such as profile assembly machines (OFAs) and the like. The assembly machine 10 includes a frame 12 providing a structural body 14 including covers 16a, 16 b. The frame 12 may include a plurality of legs for allowing the assembly machine 10 to stand. Assembly machine 10 includes a plurality of feeder banks 18a, 18 b. A plurality of feeders 20 are disposed on (as shown in fig. 2A), attached to, or otherwise mounted on each feeder bank 18a, 18 b. Each feeder 20 comprises a plurality of electronic components and the assembly machine 10 is arranged to pick up these electronic components to be placed on the PCB for assembly or at least partial assembly of the PCB. The assembly machine 10 also includes board handling holes 22. A board handling track 24 may extend in body 14 of assembly machine 10 between aperture 22 and another aperture (not shown) on the opposite side of assembly machine 10. The board handling rails 24 may be configured to receive PCBs or other unfinished products and deliver the PCBs to a placement location in the body of the assembly machine 10 for assembly. The assembly machine 10 is shown to also include operator interface and control displays 26a, 26b, one on each side. The display screen 26 may be configured to receive user or operator input and display information necessary or useful to the user or operator. While the features of the illustrated assembly machine 10 are an exemplary embodiment, it will be apparent to those skilled in the art that the various aspects of the invention described herein may be applied to various other types of assembly machines.

Referring to fig. 2A, the assembly machine 10 is shown with the covers 16a, 16b removed to expose the interior 28 of the assembly machine 10. Assembly machine 10 includes two additional feeder banks 18c, 18d disposed on body 14 on opposite sides of feeder banks 18a, 18 b. Plate handling rails 24 may be located between feeder banks 18a, 18b and feeder banks 18c, 18 d. The board handling track 24 may be configured to supply unfinished products, such as PCBs, to a placement station 30 along the track 24.

Assembly machine 10 may facilitate movement of parts in three axes of motion: an X-axis, a Y-axis, and a Z-axis. Hereinafter, the X-axis may be an axis extending parallel to the plate handling rail 24. The Y-axis may be perpendicular to the X-axis and the plate handling rails 24. The Z axis may be up and down or a longitudinal axis. The assembly machine 10 may include a plurality of axes of motion 32, 34, 36, 38 for movement in the X and Y axes. In particular, assembly machine 10 may include a first axis of motion 32 and a second axis of motion 34 arranged to facilitate motion in the Y-axis. Assembly machine 10 may include a third axis of motion 36 and a second axis of motion 38 configured to facilitate movement in the X-axis. First and second axes of motion 32 may extend along the depth of the machine between first side 40 and second side 42. The first side 40 is the side of the assembly machine 10 adjacent the first and second feeder banks 18a, 18 b. The second side 42 is the side of the assembly machine 10 adjacent the third and fourth feeder banks 18c, 18 d. Third and fourth axes of motion 36, 38 are shown connected to first and second axes of motion 32, 34 and extending between first and second axes of motion 32, 34. During operation of the assembly machine 10, the third and fourth axes of motion 36, 38 are arranged to move independently of each other along the first and second axes of motion 32, 34 to provide motion in the Y-axis. Spindle libraries 100a, 100b are shown movably attached to the third and fourth axes of motion 36, 38, respectively. The spindle libraries 100a, 100b may each be configured to move along the X-axis by moving along the third and fourth axes of motion 36, 38, respectively. In other embodiments, assembly machine 10 may be a single axis of motion machine. For example, there may be a single X-axis and a single Y-axis connectable to the assembly machine, rather than two each as shown in the embodiments of the figures.

By means of the movement axes 32, 34, 36, 38, the spindle magazine 100a, 100b in the assembly machine 10 is arranged with an X-axis and a Y-axis freedom of operation in the interior 28. This allows the spindle magazine 100a, 100b to reciprocate from the feeder magazine 18a, 18b, 18c, 18d to the placing station 30. This is accomplished by movement of the spindle libraries 100a, 100b along the third and fourth axes of motion 36, 38 and the third and fourth axes of motion 36, 38 along the first and second axes of motion 32, 34, respectively. Other forms of X-axis and Y-axis motion within the assembly machine 10 are also contemplated, with the axes of motion shown for exemplary purposes.

Referring now to fig. 2b, there is shown an enlarged perspective view of the assembly machine 10 at the location of circle a (from fig. 2A). The enlarged portion shows the spindle magazine 100a provided with a base 110 and a bearing system 112. The base 110 may be a body, a housing, a structure, or the like. The base 110 may include a plurality of mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h configured to receive spindle modules 200a, 200b, 200c, 200d, 200e, 200f, 200g, 200h, respectively. The spindle module described herein may be a pick-and-place spindle module specifically configured for receiving a spindle and nozzle combination configured to pick, place, or otherwise manipulate electronic components for printed circuit board assembly and pick-and-place processing. The spindle modules described herein may also be used in other assembly processes where one or more rotatable and/or lowerable steering spindles are necessary to perform at least a part of the assembly process of unfinished products.

The bearing system 112 may be a system for movement of the spindle magazine 100a along the third axis of motion 36. The bearing system 112 may include rollers that facilitate movement between the spindle magazine 100a and the motion axis 36. In other embodiments, the bearing system 112 may include magnets to facilitate magnetic movement between the spindle library 100a and the third axis of motion 36. The third motion shaft 36 may include a bottom surface track structure (not shown) that cooperates with the raceway structure bearing system of the spindle magazine 100 a. For example, the spindle magazine 100 may include roller bearings that mate with the tracks of the third motion shaft 36. A motor or other motion generating mechanism may be provided for controllable driving motion of the spindle magazine 100 along the third axis of motion 36. The motor may be located on the spindle magazine 100, or may be located on the third axis of motion 36. Thus, the spindle library 100 may include one or more power ports, connectors, etc. for connecting to the power system of the assembly machine 10 to provide power to the spindle library 100. The spindle library 100 may use this electric drive motor or provide movement, motion or acceleration of the spindle library 100 relative to the third axis of motion 36.

The mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h are provided for modularity within the spindle magazine 100a, so that the spindle magazine 100a can operate the respective spindle module 200a, 200b, 200c, 200d, 200e, 200f, 200g, 200h attached or operate a single spindle module. In other words, the spindle magazine 100a can operate regardless of how many of the spindle modules 200a, 200b, 200c, 200d, 200e, 200f, 200g, 200h are mounted at the mounting positions 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114 h. If one of the spindle modules 200a, 200b, 200c, 200d, 200e, 200f, 200g, 200h is damaged or needs servicing, the spindle magazine 100a may be operated. Further, although the illustrated spindle modules 200a, 200b, 200c, 200d, 200e, 200f, 200g, 200h are the same or similar, the mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h may each be configured to accommodate different types of spindle modules having different types of spindles, nozzles, etc. The mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h may each have the same physical mounting characteristics such that the spindle modules 200a, 200b, 200c, 200d, 200e, 200f, 200g, 200h may each include the same mounting characteristics such that each module may be interchangeably mounted in any mounting location. In other embodiments, the spindle library 100a may include mounting locations having different physical attachment characteristics for providing mounting for modules having different attachment mechanisms or characteristics than other modules that may be attached at other mounting locations on the spindle library 100 a.

Referring now to FIG. 3, a spindle module 200 is shown. The spindle module may be identical to one of the spindle modules 200a, 200B, 200c, 200d, 200e, 200f, 200g, 200h shown in fig. 2B. The spindle module 200 is shown as including a module body structure 210. The modular body structure may include a first body structure 212 and a second body structure 214 mounted or attached to the first body structure 212. The second body mechanism 214 includes a first receiving position 216 configured to receive the first spindle 300a and a second receiving position 218 configured to receive the second spindle 300 b.

The spindle module 200 also includes a first Z-axis motor 220 and a second Z-axis motor 222, both mounted on the second body structure 214. The first Z-axis motor 220 may be provided to move the first spindle 300a in the Z-axis direction. Similarly, a second Z-axis motor 222 may be provided to move the second spindle 300b in the Z-axis direction. The spindle module 200 also includes a first theta motor 224 and a second theta motor 226. The first theta motor 224 may be provided to rotate the first spindle 300a along a theta (theta) rotation axis. The second theta motor 226 is provided to rotate the second spindle 300b along the theta (theta) rotation axis. The first and second theta motors 224, 226 may be arranged to provide theta axis rotation in both directions. Thus, the spindle module 200 may provide motion along the Z-axis and rotational motion along the theta (θ) axis of rotation. The spindle module 200 can provide independent motion to the first and second spindles 300a, 300b, respectively.

The spindle module 200 may also include an air distribution system including one or more valves 228, 230, first and second air distribution ports 232, 234 (shown in fig. 12A and 13A), and two air flow conduits 236 (one shown) that provide vacuum generated air flow to the first and second spindles 300a, 300b, respectively. The air distribution system may also include pneumatic connections 256 (one shown) on each side. The first and second gas distribution ports 232, 234 may each be configured to receive gas from the gas distribution system of the assembly machine 10 and deliver the received gas to the first and second spindles 300a, 300 b. After the gas distribution ports 232, 234 receive gas, an internal gas flow conduit (not shown) may provide this gas flow to the pneumatic fitting 256. The gas flow conduit 236 may be connected to the pneumatic fitting 256 by extending the gas flow conduit or additional conduits may be used to separately connect the pneumatic fitting 256 to the gas flow conduit 236. In the illustrated embodiment, the first valve 228 is received in a widened portion of the first body structure 214 and may provide a gas pressure of forward blowing gas. The second valve 230 is also shown as being received in the widened portion of the first body structure 214 and may be a valve that provides vacuum pressure for picking up parts using the first and second spindles 300a, 300 b.

The spindle module 200 may have a first outer body 238a and a second outer body 238b mounted to the first body structure 212 by a number of screws. The outer bodies 238a, 238b may be a first circuit board and a second circuit board. As shown, the spindle module 200 includes a power distribution system including a second circuit board assembly 251, the second circuit board assembly 251 including a plurality of power distribution ports 242a, 242b configured to receive power from the pick-up machine 10 and/or the spindle magazine 100a or 100b when connected and to deliver the received power to the first and second Z- axis motors 220, 222 and the first and second theta motors 224, 226. When the spindle module 200 is connected to the mounter 10, each of the power distribution ports 242a and 242b can be connected to an electrical connector of the mounter 10 or the spindle magazine 100a or 100 b.

In one embodiment, the ports 240a, 240b may be configured to deliver power from the distribution ports 242a and 242b to the circuit board assemblies 238a and 238b and to the electrical connectors 252, 254, 257. It should be understood that the same electrical connectors as electrical connectors 252, 254, and 257 are provided on opposite sides of outer body 238 a. Thus, power may pass through port 242a, through 240a and 238a, and through electrical connector 257, via a cable (not shown), to first Z-axis motor 220. Similarly, power may be passed through port 242a, through 240a and 238a, and through electrical connector 252 to the first θ motor 224 via a cable (not shown). The connector 254 may be used to connect to a spindle module optical detector 550 (described below, cable not shown), to the motion control chip 250 located on 238 a. This power arrangement may be replicated on the other side of the second body 238b relative to the printed circuit board.

The spindle module 200 may comprise one or more mechanical connection mechanisms for connecting the spindle module 200 to the assembly machine 10, for example to a spindle magazine, for example one of the spindle magazines 100a, 100 b. In the illustrated embodiment, the mechanical connection mechanism includes a first threaded screw 246a and a second threaded screw 246 b. In one embodiment, the mechanical attachment mechanism may be attached using only a non-powered hand tool, such as a screwdriver, allen wrench, or the like. In the illustrated embodiment, a socket head wrench may be used to turn the first and second threaded screws 246a, 246b at the bolt heads 248a, 248b (as shown in fig. 5). Furthermore, the only procedure or step required to connect the spindle module 200 to one of the spindle libraries 100a, 100b may be to tighten the threaded screws 246a, 246 b. Similarly, the only procedure or step required to disengage or remove the spindle module 200 from one of the spindle libraries 100a, 100b is to loosen the threaded screws 246a, 246 b.

Attachment of the spindle module 200 may be accomplished, executed or otherwise implemented such that the gas distribution port is connectable for receiving gas from the mounter 10 and/or the spindle magazine 100a or 100b, and the power distribution port is configured to receive power from the mounter 10 and/or the spindle magazine 100a or 100 b. The spindle module 200 may not be directly connected to any axis of motion of the assembly machine 10, such as the first, second, third or fourth axis of motion 32, 34, 36, 38. Instead, the spindle module 200 may be attached to one of the spindle libraries 100a, 100b, which in turn may be attached to one or more of the first, second, third or fourth axes of motion 32, 34, 36, 38.

The spindle module 200 may also include a first motion control chip 250, the first motion control chip 250 coupled to the first body structure 212 proximate to the second body structure 214 and the motors 220, 222, 224, 226. The opposite side of the first body structure 212 may include a second motion control chip (not shown) in a mirror image position of the first motion control chip 250. The first motion control chip 250 may be provided to control the first Z-axis motor 220 and the first θ motor 224, respectively. Thus, the motion control chip 250 may be a dedicated control chip, processor or the like arranged to control only one of the two spindles 300a, 300b comprised in the spindle module 200, in particular the first spindle 300 a. The second motion control chip may be a dedicated control chip, processor, or the like, arranged to control the second spindle 300 b. The first motion control chip 250 and the second motion control chip may each be configured to control the speed, acceleration, and position of the respective first and second Z- axis motors 220, 222 and first and second theta motors 224, 226. Furthermore, the first motion control chip 250 and the second motion control chip may each be configured to create an independent and/or separate motion control configuration for each of the first and second spindles 300a, 300b, respectively.

Referring now to fig. 4 and 5, a perspective view and a side view of the second body structure 214 are shown, respectively, prior to attachment to the first body structure 212.

The upper structural portion 260 includes a first Z-axis motor mounting face 266 and a second Z-axis motor mounting face 268. The first Z-axis motor mounting face 266 is shown flush with the front end 269 of the upper structural portion 260, while the second Z-axis motor mounting face 268 extends from a mid-point in the depth direction of the upper structural portion that is closer to the front end 269 than to the opposite rear end. The first and second Z-axis motor mounting surfaces 266 and 268 may be spaced apart along the X-axis and Y-axis. Further, the first Z-axis motor mounting face 266 may face a first direction and the second Z-axis motor mounting face 268 may face a second direction opposite the first direction. The first and second z-axis mounting surfaces 266, 268 may include removed portions 276a, 276b, respectively, the removed portions configured to reduce the weight of the second body structure 214.

In one embodiment, the first and second mounting surfaces 266, 268 may be positioned such that when mounted, the first and second Z- axis motors 220, 222 have a vertical Z-axis spacing of at least 18 mm. In other embodiments, the first and second mounting surfaces 266, 268 may be positioned such that when installed, the vertical Z-axis spacing of the first and second Z- axis motors 220, 222 does not exceed 18 mm. In still other embodiments, the first and second mounting surfaces 266, 268 may be positioned such that, when installed, the vertical Z-axis spacing of the first and second Z- axis motors 220, 222 is at least 16 mm. In one embodiment, the first and second mounting surfaces 266, 268 may be positioned such that when installed, the total spacing between the vertical Z axes of the first and second Z axis motors 220, 222 is at least 18mm, and the spacing along the X axis is at least 10 mm. Accordingly, the first and second mounting faces 266, 268 may be positioned such that, when installed, the vertical Z-axes of the first and second Z- axis motors 220, 222 are diagonally spaced relative to the X-axis and the Y-axis.

Upper struts 270, struts, etc. extend to the top of the upper structural portion 260, which is configured to provide a second attachment location. Upper strut 270 may include another opening 272 or hole configured to receive first threaded screw 246a and head 248a for connecting modular body structure 210 to spindle library 100a, 100 b.

The lower structural portion 262 extends downwardly from the intermediate structural portion 258. The lower structural portion 262 includes a depth extending along the y-axis from a front end 277. The lower structural portion 262 includes a lower rectangular removed portion 273 that is configured to reduce the weight of the second body structure 214. The lower structural portion 262 may be a U-shaped structure extending from the middle portion 258. The front end 277 of the U-shaped structure of the lower structural portion 262 includes a first linear rail 278 mounted or otherwise connected to the front surface and a second linear rail 280 mounted or otherwise connected to the opposite rear surface such that the first linear rail 278 and the second linear rail 280 each extend along the z-axis.

The first body 282 is shown connected to the first linear track 278 and the second body 284 is shown connected to the second linear track 280. As shown in fig. 7-8 and described below, the first body 282 is operatively connected to the first Z-axis motor 220 such that the first body 282 moves along the first linear track 278 when the first Z-axis motor 220 is activated. Similarly, the second body 284 is operatively connected to the second Z-axis motor 222 such that when the second Z-axis motor 222 is activated, the second body 284 moves along the second linear track 280. The first and second bodies 282, 284 are each a linear bearing system configured to be integrated with the first and second linear rails 278, 280, respectively. In one embodiment, the first and second bodies 282, 284 may be configured to slidably move along the first and second linear rails 278, 280, respectively. In other embodiments, the first and second bodies 282, 284 can house rollers or wheels configured to facilitate movement along the first and second tracks 278, 280. To connect the first and second bodies 282, 284 to the first and second tracks 278, 280, respectively, the first and second bodies 282, 284 may be slid into the tracks from the bottom. Once the first and second bodies 282, 284 are operatively connected to the first and second Z- axis motors 220, 222, respectively, downward Z-axis movement of the first and second bodies 282, 284 may be limited by movement of the first and second Z- axis motors 220, 222 to securely connect the first and second bodies 282, 284 to the first and second tracks 278, 280.

Referring now to fig. 6, a partial exploded view of the second body structure 214 is shown, the second body structure 214 having attached thereto a first Z-axis motor 220 and a second Z-axis motor 222, a first theta motor 224 and a second theta motor 226 detached from the second body structure 214, and first and second spindles 300a, 300b detached from the first and second receiving locations 216, 218, respectively. The third body structure 286 is shown connected to the first body 282 and the fourth body structure 288 is shown connected to the second body 284. The third and fourth body structures 286, 288 are shown connected to the first and second bodies 282, 284 by screws or bolts 290a, 290b, which screws or bolts 290a, 290b are threadably received in openings 291a, 291b (shown in fig. 4) in the first and second bodies 282, 284. Third and fourth body structures 286, 288 may be provided for connecting the first and second theta motors 224, 226 to the movable first and second bodies 282, 284. As such, the first and second θ motors 224, 226 can be operatively connected to the first and second bodies 282, 284, respectively. The third and fourth body structures 286, 288 may include first and second receiving locations 216, 218 for receiving the first and second spindles 300a, 300b, respectively. Additionally, the third and fourth body structures 286, 288 may include a top location that interfaces and/or is otherwise coupled with an extension of the Z- axis motors 220, 222.

The third and fourth body structures 286, 288 each include a theta motor connection location 292, 294 therein configured to receive the first and second theta motors 224, 226, respectively. The theta motor connection locations 292, 294 may each be semi-circular. The theta motor connection positions 292, 294 may be offset from the receiving positions 292, 294, respectively, such that the motor drive gears 295, 296 of the first and second theta motors 224, 226 can mesh with the theta gears 310 of the spindles 300a, 300 b. In one embodiment, the spacing S between the first receiving location 216 and the second receiving location 218 is equal to or less than 10 mm. In other embodiments, the spacing S may be equal to or less than 8 mm. In other embodiments, the spacing may be equal to or less than 12 mm.

Referring now to fig. 7A and 7B, a mechanism and method of connecting the first and second linear rails 278, 280 to the second body structure 214 is illustrated. In particular, fig. 7A shows a side view of the spindle module 200. 3 fig. 37 3B 3 shows 3a 3 cross 3- 3 sectional 3 view 3 of 3 the 3 second 3 body 3 structure 3 214 3 of 3 the 3 spindle 3 module 3 200 3 along 3 arrow 3a 3- 3a 3 at 3 the 3 location 3 where 3 the 3 first 3 and 3 second 3 linear 3 rails 3 278 3, 3 280 3 are 3 joined 3. 3 As shown in fig. 7B, the first and second linear rails 278, 280 are attached to the lower structural portion 262 of the second body structure 214 of the modular body structure 210 of the spindle module 200 by fixing screws 297 extending between the first and second nuts 298a, 298B. As shown, the set screw 297 may include external threads. Each of the first and second nuts 298a, 298b may include an internally threaded nut body 299a, 299b configured to receive the external threads of the set screw 297.

The first and second linear rails 278, 280 may include apertures 291a, 291b configured to receive heads 293a, 293b of the first and second nuts 298a, 298b, respectively. In particular, the first linear track 278 may include a first aperture 291a configured to receive the first head 293a when the first nut 298a is tightened such that the first nut 298a does not interfere with movement of the first body 282 on the first linear track 278. Similarly, the second linear rail 280 may include a second bore 291b configured to receive the second head 293b when the second nut 298b is tightened such that the second nut 293b does not interfere with movement of the second body 284 on the second linear rail 280.

To attach the first and second linear rails 278, 280 to the second body structure 214, the process includes inserting a set screw 297 into the respective openings of the first and second linear rails 278, 280 while aligned with the opening of the second body structure 214, and then inserting nuts 298a, 298b to engage the internally threaded nut bodies 299a, 299b with the external threads of the set screw 297. Next, the process includes tightening the first and second nuts 298a, 298b until tightened. In one embodiment, only one set screw and nut combination may be required to fully connect the first and second linear rails 278, 280. In another embodiment, a second set screw may extend between the third and fourth nuts at a location spaced from the first set screw 297, the first nut 298a, and the second nut 298 b.

Referring now to fig. 8 and 9, a spindle 300 is shown. In particular, fig. 8 shows a perspective view of the spindle 300, and fig. 9 shows a side view of the spindle. Spindle 300 may include the same features as spindles 300a, 300 b. Spindle 300 includes theta gear 310, shaft 312, and nozzle tip 314. The main shaft 300 may extend between a first lower end 328 and a second upper end 330.

The spindle 300 may be considered a spindle-nozzle combination. The nozzle tip 314 is configured to contact an electronic component to manipulate the electronic component. Further, the main shaft 300 may include a rotation shaft 312 and a theta gear 310 to rotate. The spindle 300 may be configured to be interchangeable on a dispensing head or pick-and-place head, or may be removably attached to a dispensing head or pick-and-place head (e.g., the spindle magazine 100 and spindle module 200 combination). When the spindle 300 is not connected to the spindle module 200 and/or the spindle magazine 100, the spindle 300 can be found in the nozzle magazine of the assembly machine 10.

Spindle 300 may be configured to provide vacuum suction to electronic components through nozzle tip 314 to enable picking or other manipulation of electronic components through nozzle tip 314. To provide a flow of gas or vacuum force to nozzle tip 314, shaft 312 may include an outer body 316 having a hollow interior 318. Spindle 300 may be configured to provide an outward blowing airflow through nozzle tip 314 to electronic components for placement of the electronic components. In other embodiments, other types of nozzles are contemplated for use with the spindle 300, such as nozzles configured to provide material to an unfinished product.

Theta gear 310 may be mounted to shaft 312. The theta gear 310 may include a plurality of teeth 320 evenly distributed over the circumference of the theta gear 310. Teeth 320 of theta gear 310 may be configured to mesh with a theta motor, such as one of theta motors 224, 226. For example, the teeth 320 may be configured to mesh with a motor drive gear, such as one of the motor drive gears 295, 296 of the theta motors 224, 226.

The shaft 312 may be cylindrical. Theta gear 310 may be fixed, connected, or otherwise integrated with shaft 312 such that a motor drives gear to rotate theta gear 310 and rotation of theta gear 310 rotates shaft 312. In some embodiments, theta gear 310 may be a component manufactured separately from shaft 312. Theta gear 310 may include a circular inner opening configured to receive shaft 312.

The outer body 316 of the rotating shaft 312 includes a first opening 322 configured to receive the airflow into the hollow interior 318. For example, the airflow conduit 236 of the spindle module 200 may be configured to deliver airflow through the first opening 322 to the hollow interior. The outer body 316 of the rotating shaft 312 includes a second opening 324 configured to receive the airflow into the hollow interior 318. The airflow conduit 236 of the spindle module 200 may be configured to deliver airflow to the hollow interior through the second opening 324. The second opening 324 may be located on an opposite side of the rotation axis 312 from the first opening 322. Although the embodiment shown in fig. 8 and 9 includes two openings 322, 324, more or fewer openings are contemplated. As shown, both the first and second openings 322, 324 may be disposed at a point along the length of the shaft on the outer body 316 about the axis of rotation 312.

The theta gear 310 may also include an upper surface 326 facing the second upper end 330, and a lower surface 332 facing the first lower end 328. The theta gear 310 may include an outer circumference along which teeth 320 are disposed. The theta gear 310 may also include a circumferential ridge 334 extending from the upper surface 326 toward the first lower end 328. The circumferential ridge 334 may be a ring, protrusion, or the like, and may be located between the outer circumference of the theta gear 310 and the shaft 312.

Theta gear 310 may also include a lower base 336 and an upper base 338. The lower base 336 may extend from the lower surface 332 toward the first lower end 328 of the spindle 300. The lower base 336 may be located proximate to the opening of the theta gear 310 and may extend along the length of the opening of the theta gear 310 and the length of the shaft 312. The lower base 336 and the upper base 338 may be configured to support the connection of the theta gear 310 to the shaft 312.

In one embodiment, the shaft 312 may be made of a magnetic material to magnetically attach the spindle 300 to a receiving location, such as one of the receiving locations 216, 218 of a dispensing head or a pick-and-place head, such as the spindle module 200 and/or the spindle magazine 100. As described below, the magnetic material may provide a detachable connection between the spindle 300 and a dispensing head or a pick-and-place head.

Spindle 300 is shown as a spindle-nozzle combination including a toothed arrangement driven by a toothed gear. However, the spindle 300 may also be a spindle-nozzle combination: the theta gear is a magnetic gear rather than a toothed gear. The magnetic theta gear may be driven by a magnetic theta motor. Regardless of the drive mechanism utilized, the spindle 300 may include a nozzle and an integrated device that provides for rotation of the nozzle.

Referring now to fig. 10, a side cross-sectional view of the spindle module 200 of fig. 3 is shown. In particular, fig. 10 shows the first Z-axis motor 220 coupled to the third body structure 286. It should be appreciated that the features illustrated with respect to the first Z-axis motor 220 and the third body structure 286 described below may be adapted to couple the second Z-axis motor 222 to the fourth body structure 288.

The first and second Z- axis motors 220, 222 include movable shafts 516a, 516b, respectively, each of which is arranged to move relative to the motor body. The first and second Z- axis motors 220, 222 include springs 518a, 518b adjacent to covers 520a, 520 b. The springs 518a, 518b may be configured to return the movable shafts 516a, 516b to a starting position after being driven by the Z- axis motors 220, 222. The upper end of each shaft 516a, 516b is coupled to a respective cap 520a, 520b by inserting the threaded structure of the cap into the threaded hole of the shaft 516a, 516 b. Threaded set screws 514 are provided at the bottom of the shafts 516a, 516b, respectively, to connect the shafts to the third and fourth body structures 286, 288, respectively. Thus, when the Z- axis motors 220, 222 are activated, and the shafts 516a, 516b are displaced downward, the respective connected body structures, including the respective nozzles 300a, 300b and the respective theta motors 224, 226 are also displaced downward.

Furthermore, the first accommodation position 216 is shown after the first spindle 300a is accommodated in the bore of the first accommodation position 216. The first receiving location 216 and the shaft 312 of the first spindle 300a may include relatively tight tolerances to allow the shaft 312 to slide and rotate along the z-axis without other movement. The shaft 312 of the first primary shaft 300a may be magnetic and may be attracted to a magnet 510 located or disposed within the third body structure 286. This may create a retaining force to retain the first spindle 300a in the first receiving position 216. However, if it is desired to remove the first spindle 300a from the first receiving location 216, the holding force may be overcome with greater force. In this way, the first spindle 300a can be detachably connected to the first accommodation position 216. As shown, a spindle spring 512 may be disposed within the third body structure 286. The spindle spring 512 may provide a small amount of spring movement when the spindle 300a picks and/or places components, when the spindle 300a is impeded by upward forces from the immovable feeder garage (during pick up) and the unfinished product or PCB (during placement). In other embodiments not shown, the spindle spring 512 may be replaced by a magnet that provides a resistive magnetic force to a corresponding magnet of the spindle 300 a.

Fig. 11 shows a front view of the spindle module 200 when the first Z-axis motor 220 is activated. As shown, the second Z-axis motor 222 remains in an upward unactuated position. When actuated, the shaft 516a and spring 518a are compressed. When actuated, the shaft 518a thus protrudes from the bottom of the body of the Z-axis motor 220. The connection position 522a between the shaft 518a and the third body structure 286 is thus moved downward, moving the first body 282, the first theta motor 224, the first receiving position 216, and the first spindle 300a downward. Meanwhile, the connection position 522b between the shaft 518b and the fourth body structure 288 remains stationary with the second body 284, the second theta motor 226, the second receiving position 218, and the second spindle 300 b.

Fig. 12A shows a perspective view of the spindle module 200 when the first Z-axis motor 220 is activated, and a circle B is drawn around a portion of the spindle 300 a. Fig. 12B shows an enlarged perspective view of the spindle module 200 at the location of circle B, from which enlarged view of fig. 12B it can be seen that the spindle module optical detector 550 extends from the third body structure 282 connected to the first body 282. The optical detector 550 may be configured to detect upward movement of the received first spindle 300a relative to the first body 282 and the third body structure 282. It should be understood that the spindle module 200 may include a second optical detector positioned in the same manner for detecting movement of the received second spindle 300 b.

As shown in fig. 12B, spindle 300a is in a downward rest position before spindle 300a contacts an electronic component for pick-up, or before spindle 300a contacts a PCB or other unfinished product during placement. During this rest position, the teeth 320 of the spindle 300a mesh with the teeth of the first θ motor drive gear 295. Further, the circumferential ridge 334 of the first spindle 300a does not extend into the opening 552 between the first end 554 and the second end 556 of the optical sensor 550. A first end 554 of the optical sensor 550 may include an optical beam generator 558 and a second end 556 of the optical sensor 550 may include a photodetector. When the circumferential ridge 334 is located in the opening 552, the circumferential ridge 334 may cut off the light beam. This may be arranged to be detected immediately upon a touch during pick and/or place.

Fig. 13A shows a perspective view of the spindle module 200 when the first Z-axis motor 220 is activated, and a circle C is drawn around a portion of the spindle 300 a. Fig. 13B shows an enlarged perspective view of the spindle module 200 at the circle C. As shown in fig. 13B, the main shaft 300a has now moved upward relative to the first body 282 and the third body structure 282. Accordingly, the circumferential ridge 334 is located in the opening 552, thereby cutting off the light beam of the optical sensor 550. It should also be noted that the first theta motor drive gear 295 has a height sufficient to maintain contact with the teeth 320 of the nozzle 300a as the nozzle 300a moves relative to the first theta motor drive gear 295. In one embodiment, the first theta motor drive gear 295 has a height greater than the maximum displacement permitted between the main shaft 300a and the first and third body structures 282, 282.

Referring first to fig. 14, one of the spindle modules 200 is connected to the spindle magazine 100. The spindle magazine 100 includes a base 110 and mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114 h. In the illustrated embodiment, the base 110 includes eight mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114 h. In other embodiments, more or fewer mounting locations are contemplated. For example, the spindle magazine may have as few as one mounting location, or as many mounting locations as possible spanning half the width of the assembly machine minus half the width of a predetermined unfinished product that the assembly machine is intended to at least partially assemble when connected to the spindle magazine 100. This arrangement enables the left and right most spindles in the spindle module to reach each point along the X axis of the unfinished product.

The plurality of mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h are each configured to receive a mountable spindle module, such as the mountable spindle module 200 as shown. The spindle magazine 100, when combined with one or more spindle modules 200, may be a dispense head or pick-and-place head of the assembly machine 10. Unlike typical dispense heads or pick-and-place heads, the spindle magazine 100 may provide a modular design for simple mechanical attachment and detachment of individual modular spindle modules, such as the spindle module 200. The modular nature of the spindle connection may provide for easier maintenance when the spindle assembly requires servicing. Further, while the spindle module 200 is described above as an example, various other spindle modules may be matched with the spindle magazine 100, such as the spindle module 500 shown in fig. 15. The modularity of the spindle library 100 and spindle module combinations may provide flexibility to the system. The dispense heads defined by the spindle magazine 100 and spindle modules 200, 500 can be easily reconfigured with the various spindle modules in any set up required for the assembly process.

In the illustrated embodiment, the centers of each of the mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h may be spaced less than 25mm apart. In other embodiments, the centers of each mounting location 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h may be spaced less than 20mm apart. Any spacing may be considered for the mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h, however, it is difficult but desirable to reduce the size and weight of the spindle magazine 100 by reducing the spacing by making each spindle module 200 as thin as possible. The structure of the spindle module described above includes various features that provide a thin spindle module 200, such as the spacing of the Z- axis motors 220, 222, features of the modular body structure 210, and the like.

Spindle magazine 100 includes a bearing system 112, which includes a first bearing 116 and a second bearing 118, for connecting spindle magazine 100 to a motion axis of a mounting machine, such as third motion axis 36 or fourth motion axis 38. The bearing system 112 can cooperate with tracks established in the axes of motion 36, 38 of the assembly machine 10. In other embodiments, the bearing system 112 of the spindle magazine 100 may include rollers (wheels) or balls to facilitate movement (not shown). In other embodiments, the bearing system 112 may include raceways of other shapes for integration with a rail system. In still other instances, the spindle library 100 may include a dynamic bearing system that uses a roller or magnetic force to move the spindle library 100 along the connected axis of motion. In other cases, the shaft includes a motion system and the spindle library 100 is not driven in motion, but rather is attached to the shaft and moved by the motion system driven by the shaft. In some embodiments, a permanent magnet and coil system may be utilized, wherein the spindle library 100 acts as a permanent magnet or a movable coil, while the shaft acts as the other of the permanent magnet or the movable coil. The spindle library 100 may include any system for movably coupling the spindle library 100 to one or more axes for movement.

The spindle library 100 also includes an air distribution system including a first inlet 122 and a second inlet 124. Both the first inlet 122 and the second inlet 124 may be connected from the assembly machine to a pipe or other gas delivery system. From the first gas inlet 122, a channel may extend having different gas outlets 128a, 128b, 128c, 128d, 128e, 128f, 128g configured to each deliver gas to a gas distribution port, such as the first gas distribution port 232 of the spindle module 200. Similarly, a channel may extend from the second gas inlet 124 having different gas outlets 128a, 128b, 128c, 128d, 128e, 128f, 128g configured to each deliver gas to a gas distribution port, such as the second gas distribution port 234 of the spindle module 200. It should be understood that in the embodiment shown in fig. 14, the spindle module 200 to which the two gas outlets of the spindle magazine 100 are connected is hidden. In this way, a plurality of mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h, respectively, may be provided to deliver gas to each mountable spindle module when the module is mounted.

The spindle library 100 may also include a power delivery system to deliver power and/or signals to the various mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114 h. The power delivery system is shown to include a set of electrical connectors 132. The set of electrical connectors 132 may be configured to connect to the power distribution ports 242a, 242b of the respective spindle modules 200. The spindle magazine 100 may include one or more electrical input connectors (not shown) to provide power and/or other signals to the spindle magazine 100, the spindle magazine 100 being connected to electrical connectors 130, 132 located at a plurality of mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114 h.

Each of the mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h may include a first threaded connection location 134 configured to receive a first threaded screw 246a of the spindle module 200. Each of the mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h may include a second threaded connection location 136 configured to receive a second threaded screw 246b of the spindle module 200. Both the first threaded connection location 134 and the second threaded connection location 136 may be threaded holes. Thus, as described above, each spindle module 200 can be installed and removed from the spindle magazine 200 by applying or removing two threaded screws. A manual tool, such as a screwdriver, allen wrench, etc., may be the only tool required to install the spindle module 200 to the spindle magazine 100.

Fig. 15 shows a plurality of spindle modules 200a, 200b, 200c, 200d, 200e, 200f, 200g connected, and a spindle module 500 different from the spindle modules 200a, 200b, 200c, 200d, 200e, 200f, 200 g. Thus, the plurality of mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h comprise a first mounting location 114a configured to receive a first mountable spindle module 500. The plurality of mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h may comprise respective second mounting locations 114b, 114c, 114d, 114e, 114f, 114g, 114h arranged to receive a second mountable spindle module 200. In some embodiments, the first and second mounting locations 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114h may be structurally identical. In other embodiments, the spindle library 100 may include structural differences between mounting locations. Thus, the first mountable spindle module 500 is different from the second mountable spindle modules 200a, 200b, 200c, 200d, 200e, 200f, 200 g. For example, the first mountable spindle module 500 includes a single spindle and nozzle, while the second mountable spindle modules 200a, 200b, 200c, 200d, 200e, 200f, 200g each include two spindles and nozzles. The first mounting location 114a may include at least one physical characteristic that is different from the second mounting locations 114b, 114c, 114d, 114e, 114f, 114g, 114h when accommodating different spindle modules. A spindle library is envisaged which accommodates a variety of different spindle modules having different features or physical characteristics at the mounting location.

Although not shown, it is also contemplated that the spindle library 100 includes one or more motion control chips for each mounting location 114a, 114b, 114c, 114d, 114e, 114f, 114g, 114 h. The illustrated embodiment includes a motion control chip 250 connected to each attachable spindle module 200. However, in other embodiments, these motion control chips may be built on the spindle library 100. Regardless of the embodiment, the dispensing head or pick-and-place head defined by the combination of the spindle magazine 100 and the connectable spindle modules 200, 500 may comprise a number of control chips 250 equal to the number of spindles. In other embodiments, each spindle module 200 includes a control chip 250 dedicated to two spindles on the module.
