Detailed Description

Fig. 1 is a schematic view of a three-dimensional processing unit according to an embodiment of the present invention. Referring to fig. 1, the three-dimensional processing unit 100 of the present embodiment is used for processing a workpiece to be processed, and particularly, for performing 3D processing on an irregular surface of the workpiece to be processed, the irregular surface may be a surface of a protective shell of a mobile phone or a surface of a shell of a golf club head.

The three-dimensional processing unit 100 includes a fixing frame 110, an adjusting member 120, a fixing ring 130, a buffer member 140, and a processing device 150. The fixing frame 110 has a first side 111 and a second side 112 opposite to each other, and the adjusting element 120 is disposed on the first side 111 of the fixing frame 110. The fixing ring 130 is sleeved in the fixing frame 110 and disposed adjacent to the second side 112. The fixing ring 130 has a third side 131 and a fourth side 132 opposite to each other, wherein the buffer 140 is connected between the third side 131 of the fixing ring 130 and the adjusting element 120, and the processing device 150 is disposed on the fourth side 132 of the fixing ring 130 and is sleeved in the fixing ring 130. The fixing ring 130 can be moved closer to or farther from the conditioning member 120 by the buffer member 140 so that the processing device 150 can perform 3D processing on the workpiece to be processed along the irregular surface of the workpiece to be processed.

FIG. 2 is a schematic view of another embodiment of a three-dimensional processing unit of the present invention. The processing device 150 of the present embodiment is a blade 151 (shown in fig. 1), but in other embodiments, a polishing head 152 (shown in fig. 2) may be selected according to the type of the workpiece to be processed. The blade 151 is used for a process of carving or cutting an irregular surface of a work piece to be processed. In this embodiment, the buffer member 140 is a spring, and the fixing ring 130 can move closer to or away from the adjustment member 120 by the deformation of the spring. Referring to fig. 3, in another embodiment, the buffer member may be moved in another manner, for example, the buffer member 240 includes, but is not limited to, a combination of a gear 242 and a rack 241, and the fixing ring 130 can move up and down to approach or separate from the adjusting member 120 by the cooperation of the gear 242 and the rack 241.

The type of the buffer 140 is not limited to the combination of the spring or the gear 242 and the rack 241, and those skilled in the art can select an appropriate element or component as the buffer 140 according to the requirement.

Referring back to fig. 1, the three-dimensional processing unit 100 may further include a rotation bearing 160, wherein the rotation bearing 160 is fixed on the fourth side 132 of the fixing ring 130 and is located between the fixing ring 130 and the processing device 150. In short, the rotary bearing 160 is fixed in the fixed ring 130, and the rotary bearing 160 holds the processing device 150. In this way, when the rotation bearing 160 rotates, the processing device 150 can be driven to rotate.

FIG. 4 is a schematic view of a processing system of the present invention. Please refer to fig. 1, fig. 2 and fig. 4. The three-dimensional processing unit 100 described above may be applied to the processing system 300 to process a workpiece to be processed by the processing system 300. The following description will discuss the three-dimensional processing unit 100 applied to a processing system 300 for processing a case 200 of a golf club head.

The processing system 300 at least comprises a robot 310 and the aforementioned three-dimensional processing unit 100, wherein the robot 310 is used to pick up the housing 200 of the golf club head and move the housing 200 of the golf club head to a processing position, and the three-dimensional processing unit 100 performs a 3D processing procedure on the housing 200 of the golf club head along the irregular surface of the housing 200 of the golf club head.

In detail, the shell 200 of the golf club head has an irregularly curved contour surface, and the surface 202 of the shell 200 of the golf club head may be formed through a multi-painting process. The grinding process may also be added if it is desired to further finish the surface 202 that has been treated by the 3D process.

Before spraying paints of different colors on the surface 202, the adhesive film must be completely adhered to the surface 202 of the casing 200 of the golf club head, and the position to be painted is cut off by the blade 151, after the painting is finished and the baking is finished, another adhesive film is adhered, and the other position to be painted is cut off by the blade 151. The above-described actions are repeated until all of the paint is sprayed. Therefore, the blade 151 is first selected as the processing device 150 to perform the processing procedure of cutting off the adhesive film. In the same processing system 300, the number of the three-dimensional processing units 100 is not limited, and those skilled in the art can determine the number of the three-dimensional processing units 100 according to the requirement and change the type of the processing device 150 according to the required processing program.

In the present embodiment, two or more processing units may be provided in the same processing system 300. For example, the first processing unit 100 is the aforementioned three-dimensional processing unit 100, and the processing device 150 is a blade 151 and the buffer 140 is a spring for cutting off the adhesive film attached to the surface 202 of the casing 200 of the golf club head; the second processing unit 320 is used for attaching and removing the adhesive film on the surface 202 of the shell 200 of the golf club head; and the third processing unit 330 is used to spray paint on the case 200 of the golf club head; and the processing device 150 of the fourth processing unit 340 may optionally include a grinding head 152 to grind the surface 202 of the housing 200 of the golf club head. Thus, the same processing system 300 may provide multiple processes for grinding, attaching, cutting, painting, and peeling the surface 202 of the golf club head shell 200.

The following description will describe in detail how the machining system 300 is used to perform a machining process on the surface 202 of the golf club head housing 200.

Fig. 5A is a schematic view of a case of a golf club head held by a robot arm for processing, and fig. 5B is a schematic partial sectional view of the case of the golf club head. Fig. 6 is a flow chart of the processing of the golf club head shell 200 using the processing system 300. Please refer to fig. 4, fig. 5A and fig. 6.

In step S110, the robot 310 of the processing system 300 picks up the golf club head case 200 and moves the golf club head case 200 to a processing position. The step of moving the housing 200 of the golf club head to the machining position includes moving the housing 200 of the golf club head to a predetermined position, and further includes the robot arm 310 turning the housing 200 of the golf club head so that the surface 202 of the housing 200 of the golf club head faces the first machining unit 100.

Additionally, the tooling system 300 may further include a camera 350, wherein the camera 350 may be disposed at a tooling location for image capture of the golf club head case 200 to confirm whether the face 202 of the golf club head case 200 is flipped in the correct orientation.

Incidentally, before or after the robot 310 picks up the golf club head case 200, and before the next step S120, the method further includes attaching a glue film to the surface 202 of the golf club head case 200 by using the second processing unit 320. The second processing unit 320 may be represented by a robot 310, wherein the robot 310 has at least six axial rotational motion functions in response to the surface 202 of the casing 200 of the golf club head being a three-dimensional irregular curved surface.

Next, in step S120, the first processing unit 100 processes the casing 200 of the golf club head along the three-dimensional contour of the casing 200 of the golf club head.

In detail, the first processing unit 100 is moved to the surface 202 of the casing 200 of the golf club head, and the processing device 150 is contacted with the surface 202, so that the first processing unit 100 and the robot 310 are moved relatively, wherein the moving of the first processing unit 100 and the robot 310 may be to fix the robot 310 and move the first processing unit 100, to move the robot 310 and fix the first processing unit 100, or to move the robot 310 and the first processing unit 100 simultaneously.

When a process is performed on the surface 202 of the case 200 of the golf club head, the first processing unit 100 cuts the surface 202 according to a predetermined pattern, as shown in fig. 5A. As can be seen from fig. 5A and 5B, the surface 202 of the casing 200 of the golf ball as the workpiece to be processed has an irregular curved profile, and therefore, referring to fig. 1, when the fixing frame 110 of the first processing unit 100 is fixed at a specific height and is moved horizontally relative to the casing 200 of the golf club head, when the surface 202 of the casing 200 is processed, the processing device 150 needs to move up and down elastically in response to the height change of the surface 202 of the casing 200, so as to prevent the blade 151 from penetrating into the surface 202 too deeply and damaging the casing 200, or entering into the glue film too shallowly and failing to cut the glue film effectively.

As described above, by selecting the spring as the buffer 140, when the blade 151 contacts the adhesive film, a reaction force from the adhesive film and an elastic restoring force of the spring are primarily balanced, so that the blade 151 can enter and cut the adhesive film at a predetermined depth.

Fig. 7A to 7C are schematic diagrams illustrating the movement of the processing device 150 relative to the adjusting member 120 when the three-dimensional processing unit performs cutting along points a and B to C. More specifically, when the first processing unit 100 is used to cut off a specific range of adhesive films surrounded by points a to C, since points a, B and C have different heights, when the blade 151 moves from point a to point C, the blade 151 is forced to move toward the adjusting member 120 as the heights increase from low to high, as shown in the sequence of fig. 7A to 7C, the buffer member 140, which is a spring, is compressed and stores elastic restoring force, and the spring also presses the blade 151, so that the blade 151 can cut the adhesive films at a predetermined depth without damaging the surface 202.

Incidentally, the buffering member 140 can provide a buffering effect for the blade 151 in response to the up-and-down movement of the blade 151, and the adjusting member 120 is used to adjust the buffering capacity provided by the buffering member 140 to the blade 151, such as the tightness of a spring, so as to adjust the buffering capacity provided by the buffering member 140 to the blade 151.

Referring to fig. 5A and 5B, when the processing device 150 moves from point C to point a, as the height changes from high to low, the elastic restoring force drives the blade 151 to move away from the adjusting member 120, as shown in the sequence of fig. 7C to 7A, and the blade 151 continues to cut the adhesive film by a predetermined depth.

In addition, the processing device 150 needs to cut a complete closed area in the adhesive film, so that the adhesive film surrounded by the cut area can be torn off, or the adhesive film surrounded by the cut area is retained, and the adhesive film in the remaining area is torn off, so that the processing device 150 cuts along the predetermined pattern, and when the turning point is met, the rotating bearing 160 can drive the processing device 150 to rotate.

After the cutting is completed, the third processing unit 330 paints the surface 202 of the case 200 of the golf club head as by step S130. The third processing unit 330 may clamp a separate spray gun by the robot 310 to spray paint; alternatively, the gun and paint delivery lines may be integrated directly with the robot 310.

In step S140, the second processing unit 320 removes all of the adhesive film attached to the surface 202. Thus, the processing procedure of one-time paint spraying is completed.

As mentioned above, if there are several paints to be painted on the surface 202 of the golf club head case 200, the paint color can be changed and the above steps S110-S140 can be repeated several times. Alternatively, a plurality of third processing units 330 for painting may be provided in the same processing system 300, and each third processing unit 330 may be used for painting a different color paint.

In other embodiments, the workpiece to be processed may be other than the shell 200 of the golf club head, and the workpiece is not limited to the illustrated example, and the present disclosure mainly provides a three-dimensional processing unit, a processing system and a processing method capable of processing a three-dimensional object with irregular surface, so that the type of the processing device 150 in the three-dimensional processing unit 100 can be changed according to the actual requirement. For example, when it is required to grind an irregular surface of a workpiece to be machined, which has an irregular surface, the three-dimensional machining unit 100 may select the grinding head 152 as the machining device 150, as shown in fig. 2.

In summary, in the three-dimensional processing unit of the present invention, the fixing ring can be relatively close to or far from the adjusting element through the buffer element, so that the three-dimensional processing unit can drive the fixing frame to move in the plane direction through other moving elements for processing, and the processing device can move in the vertical direction due to the cooperation of the fixing ring and the buffer element, so that a workpiece to be processed with an irregular surface can be processed.

In addition, the three-dimensional processing unit can be applied to a processing system and a processing method, so that a good 3D processing effect can be obtained in an automatic control mode.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
