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.

Detailed Description
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
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
