[0043] The circuit board processing device provided in this application processes the circuit board as follows: first, the circuit board is fixed on the worktable, and then the transfer mechanism is started. As the transfer mechanism slides, the cutting module and the grinding roller assembly begin to perform cutting and grinding work respectively. That is, when the transfer mechanism slides along the first direction, the cutting module located on the transfer mechanism moves with the transfer mechanism and begins to cut the circuit board. The grinding module connected to the transfer mechanism moves with the transfer mechanism. During the movement, since the grinding roller assembly and the cut circuit board form edge contact, the edge of the cut circuit board can be ground as the grinding roller assembly rotates.

[0044] The advantages of this circuit board processing device mainly include: as the transfer mechanism slides along the first direction, while the cutting module cuts the circuit board, the grinding roller assembly grinds and deburrs the cut position of the circuit board. In other words, by setting up the grinding roller assembly, the cutting position of the circuit board can be ground and deburred at the same time as the cutting module cuts the circuit board. In this way, there is no need to perform an additional grinding and deburring process, saving processing time, reducing the labor intensity of workers, and improving the production efficiency of circuit boards. This solves the problem of time-consuming, labor-intensive and low-efficiency production caused by the traditional circuit board cutting process requiring an additional grinding process.

[0077] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0078] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0079] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.

[0080] Please see Figure 1 The board processing apparatus provided in this embodiment of the invention includes a worktable 10 and a processing mechanism 20.

[0081] The worktable 10 is used to fix the board 30. The processing mechanism 20 is set on the worktable 10. The processing mechanism 20 is used to cut the board 30 and polish the cut surface at the same time. That is to say, the processing mechanism 20 includes both the cutting operation of the board 30 and the polishing of the cut surface of the board 30.

[0082] Specifically, the processing mechanism 20 includes a transfer mechanism, a cutting module 23, and a grinding module 24. The transfer mechanism is movably mounted on the worktable 10 and is used to slide along a first direction. The cutting module 23 is mounted on the transfer mechanism and is used to cut the board 30 when moving along the first direction. The grinding module 24 is connected to the transfer mechanism, and the grinding module 24 and the cutting module 23 are arranged sequentially along the first direction. The grinding module 24 includes a grinding roller assembly, which is used to form edge contact with the cut board 30 and is used to rotate when the cutting module 23 cuts the board 30 to grind the edge (the edge formed by the cut board 30).

[0083] The first direction can be as follows: Figure 1 The X-axis direction is shown.

[0084] It should be noted that board 30 can specifically refer to a circuit board. Specifically, after the electronic components are assembled, the PCB (Printed Circuit Board) forms the PCBA (Printed Circuit Board Assembly), which needs to be cut and processed.

[0085] The circuit board processing device provided in this application processes the circuit board 30 as follows: first, the circuit board 30 is fixed on the worktable 10, and then the transfer mechanism is started. As the transfer mechanism slides, the cutting module 23 and the grinding roller assembly begin to perform cutting and grinding work respectively. That is, when the transfer mechanism slides along the first direction, the cutting module 23 located on the transfer mechanism moves with the transfer mechanism and begins to cut the circuit board 30. The grinding module 24 connected to the transfer mechanism moves with the transfer mechanism. During the movement, since the grinding roller assembly and the cut circuit board 30 form edge contact, the edge of the cut circuit board 30 can be ground as the grinding roller assembly rotates.

[0086] The beneficial effects of this circuit board processing device mainly include: as the transfer mechanism slides along the first direction, while the cutting module 23 cuts the circuit board 30, the grinding roller assembly grinds and deburrs the cut position of the circuit board 30. In other words, by setting the grinding roller assembly, the cutting position of the circuit board 30 can be ground and deburred at the same time as the cutting module 23 cuts the circuit board 30. In this way, there is no need to perform an additional grinding and deburring process, saving processing time, reducing the labor intensity of workers, and improving the production efficiency of the circuit board 30. This solves the problem of time-consuming, labor-intensive and low production efficiency caused by the traditional circuit board 30 needing to be ground after cutting.

[0087] Of course, depending on actual needs, the action of the above-mentioned grinding roller assembly can be driven by a separate power assembly (the power assembly can be set separately on the transfer mechanism), or a linkage mechanism can be used to drive the grinding roller assembly to rotate during the sliding of the transfer mechanism along the first direction, so as to achieve the grinding roller assembly to grind and deburr the cutting position of the board 30 while the cutting module 23 cuts the board 30, thereby achieving the grinding and deburring of the cutting position of the board 30 at the same time as the cutting module 23 cuts the board 30.

[0088] The present invention preferably employs a linkage mechanism to drive the grinding roller assembly to rotate during the sliding of the transfer mechanism along the first direction.

[0089] In some embodiments, the transfer mechanism includes a first transfer module 21 and a second transfer module 22. The first transfer module 21 includes a first sliding component 211 for sliding along a first direction. The second transfer module 22 is disposed above the first transfer module 21 and includes a second sliding component 221 for sliding synchronously with the first sliding component 211 along the first direction. The second sliding component 211 is connected to a cutting module 23, and a grinding module 24 is located between the first transfer module 21 and the second transfer module 22.

[0090] It is important to note that the edges of the cut board 30 specifically include the two vertical cut surfaces and two pairs of diagonal corners. To meet the requirements for grinding the cut surfaces of the board 30, the grinding roller assembly needs to grind both vertical cut surfaces and both pairs of diagonal corners. Therefore, the grinding roller assembly needs to be equipped with two types of grinding rollers: one for grinding the two vertical cut surfaces and the other for grinding the diagonal corners.

[0091] Please refer to the following: Figure 3 and Figure 4 The grinding module 24 includes a first grinding mechanism and a second grinding mechanism. The first grinding mechanism includes a first grinding roller 241, a first mounting component 243 and a first linkage component 244. The second grinding mechanism includes a second grinding roller 242, a second mounting component 245 and a second linkage component 246.

[0092] Specifically, the second transfer module 22 further includes a second frame 222, a second sliding assembly 221 disposed inside the second frame 222, and a grinding roller assembly including a first grinding roller 241 and two second grinding rollers 242. The two ends of the first grinding roller 241 are rotatably connected to the first sliding assembly 211 and the second sliding assembly 221, respectively. The first grinding roller 241 is used to rotate around an axis perpendicular to the first direction to grind the two vertical cut surfaces of the cut board 30. The two second grinding rollers 242 are arranged crosswise, with the two ends of any one second grinding roller 242 rotatably connected to the first sliding assembly 211 and the second frame 222, respectively. Any one second grinding roller 242 is used to grind the two diagonally opposite corners of the cut board 30.

[0093] The second direction could be as follows: Figure 1The Z-axis direction is shown. In this way, during the rotation of the first grinding roller 241 around the Z-axis, the two vertical cutting surfaces of the cut board 30 can be ground. At the same time, during the grinding process, the first grinding roller 241 and the two second grinding rollers 242 do not interfere with each other, ensuring the grinding effect on the board 30.

[0094] In some embodiments, the first sliding assembly 211 includes a first slider 2111 and a first auxiliary plate 2112, with the first auxiliary plate 2112 disposed at one end of the first slider 2111 near the second sliding assembly 221. Further, to facilitate the sliding of the first slider 2111, the first transfer module 21 also includes a first transfer motor 213 and a first lead screw 214. The first transfer motor 213 is connected to the first lead screw 214, and the first slider 2111 is movably mounted on the first lead screw 214. The first transfer motor 213 provides power so that the first lead screw 214 rotates, driving the first slider 2111 to slide.

[0095] In some embodiments, the second sliding assembly 221 includes a second slider 2211, a mounting bracket 2212, and a second auxiliary plate 2213. The mounting bracket 2212 is disposed at one end of the second slider 2211 near the first sliding assembly 211, and the second auxiliary plate 2213 is disposed on the mounting bracket 2212. The mounting bracket 2212 is U-shaped. Further, the second transfer module 22 also includes a second transfer motor 223 and a second lead screw 224. The second transfer motor 223 is connected to the second lead screw 224. The second slider 2211 is movably mounted on the second lead screw 224. The second transfer motor 223 is used to provide power so that the second lead screw 224 drives the second slider 2211 to slide after it rotates.

[0096] Please refer to the following: Figure 2 To facilitate the cutting of the board 30, the cutting module 23 includes a rotating motor 231, a cutting blade 232, a first rotating gear 233, a second rotating gear 234, and a second synchronous toothed belt 235. The cutting blade 232 is rotatably connected to the mounting frame 2212 via a rotating shaft, causing the cutting blade 232 to rotate around a third-direction axis within the mounting frame 2212. The third-direction, the second direction, and the first direction are perpendicular to each other. One end of the rotating shaft extends out of the mounting frame 2212 and is coaxially connected to the first rotating gear 233. The rotating motor 231 is mounted on the second slider 2211, and the output shaft of the rotating motor 231 is connected to the second rotating gear 234. The first rotating gear 233 and the second rotating gear 234 are synchronously connected via the second synchronous toothed belt 235 to drive the cutting blade 232 to rotate. The other end of the rotating shaft is rotatably connected to the second frame 222 via a mating plate. A rotating hole is provided on the mating plate, and the rotating shaft is rotatably disposed within the rotating hole.

[0097] The third direction can be as follows: Figure 1 The Y-axis direction is shown.

[0098] In some embodiments, the top end of the first grinding roller 241 can be rotatably connected to the second auxiliary plate 2213, and the bottom end of the first grinding roller 241 can be rotatably connected to the first auxiliary plate 2112. The first grinding roller 241 is vertically arranged, and the first grinding roller 241 grinds the two vertical cutting surfaces of the cut plate 30 by rotating around the Z-axis. The top end of the second grinding roller 242 can be rotatably connected to the second frame 222, and the bottom end of the second grinding roller 242 can be rotatably connected to the first auxiliary plate 2112. The second grinding roller 242 is inclined, and two second grinding rollers 242 are provided and staggered. Each second grinding roller 242 simultaneously abuts against the diagonal corner of the cutting surface of the two cut plates 30, thereby grinding and deburring the diagonal corner of the two plates 30.

[0099] Please refer to the following: Figure 4 , Figure 5 and Figure 6 To facilitate the installation of the first grinding roller 241, the grinding module 24 also includes a first mounting component 243. The first mounting component 243 includes a first mounting shaft 2431 and a first connecting shaft 2432. One end of the first grinding roller 241 is embedded in the first mounting shaft 2431. The first mounting shaft 2431 is rotatably connected to the first auxiliary plate 2112 of the first sliding component 211 via a bearing. The other end of the first grinding roller 241 is rotatably mounted on the first connecting shaft 2432. The first connecting shaft 2432 is fixedly connected to the second auxiliary plate 2213 of the second sliding component 221.

[0100] With this configuration, the first grinding roller 241 is provided with a first mounting shaft 2431 and a first connecting shaft 2432 at both ends, so that there are force-bearing components at both ends of the first grinding roller 241, which can ensure that the first grinding roller 241 rotates smoothly and reliably, and completes reliable grinding of the board 30.

[0101] In some embodiments, the first mounting shaft 2431 includes a first shaft body 24311 and a second shaft body 24312. The top end of the first shaft body 24311 is provided with a first slide rod 24313, and the bottom end of the second shaft body 24312 is provided with a first slide groove 24314 for the first slide rod 24313 to slide. A first locking block 24315 is slidably provided on both sides of the top end of the first slide rod 24313. A first receiving groove 24316 is provided on the side wall of the top end of the first slide rod 24313 for the first locking block 24315 to slide. A first locking groove 24317 is provided on the inner walls of both sides of the first slide groove 24314 for the corresponding first locking block 24315 to extend into. A first spring 24318 is provided in the first receiving groove 24316. The first spring 24318 is used to make the first locking block 24315 slide toward the corresponding first locking groove 24317.

[0102] It can be seen that the first spring 24318 is used to provide elastic force to the first locking block 24315 so that the first locking block 24315 has a tendency to extend into the corresponding first locking groove 24317.

[0103] Furthermore, a first cross bar 243121 is fixedly connected to the top of the second shaft 24312, and a first cross groove 2411 is provided at the bottom of the first grinding roller 241 for the first cross bar 243121 to extend into. In this way, when the first shaft 24311 rotates, it drives the second shaft 24312 to rotate via the first slide bar 24313, and when the second shaft 24312 rotates, it drives the first grinding roller 241 to rotate via the first cross bar 243121.

[0104] To facilitate the connection between the first grinding roller 241 and the first connecting shaft 2432, a first limiting block 2412 is provided on both sides of the top end of the first grinding roller 241. The top end of the first connecting shaft 2432 is fixedly connected to the second auxiliary plate 2213. The bottom end of the first connecting shaft 2432 is provided with a first rotating groove 24321 for the first grinding roller 241 to rotate and a first limiting groove 24322 for the first limiting block 2412 to pass through. The inner wall of the top end of the first rotating groove 24321 is provided with a first annular groove 24323 for the first limiting block 2412 to rotate, so that the first grinding roller 241 and the first connecting shaft 2432 are rotatably connected.

[0105] With this configuration, both ends of the first grinding roller 241 are limited along the axial direction. When installing the first grinding roller 241, the first limiting block 2412 of the first grinding roller 241 is inserted into the first limiting groove 24322 of the first connecting shaft 2432. Then, the first cross bar 243121 is aligned with the first cross groove 2411, and the second shaft 24312 is pulled upward to allow the first cross bar 243121 to enter the first cross groove 2411. At this time, the first locking block 24315 automatically enters the corresponding locking block 24315 under the action of the first spring 24318. The first grinding roller 241 is quickly fixed in a locking groove 24317. When the first grinding roller 241 needs to be disassembled, the first locking block 24315 is first pressed inward to disengage it from the first locking groove 24317. Then, the second shaft 24312 is slid downward to disengage the first cross bar 243121 from the first cross groove 2411. After that, the first grinding roller 241 is rotated so that the first limiting block 2412 is aligned with the first limiting groove 24322 to disengage the first grinding roller 241 from the first connecting shaft 2432.

[0106] In some embodiments, the first transfer module 21 includes a first frame 212, and a first sliding component 211 is located inside the first frame 212.

[0107] To facilitate the linkage of the first grinding roller 241, the grinding module 24 also includes a first linkage component 244, which includes a first linkage rack 2441, a first linkage gear 2442, a first auxiliary gear 2443, and a first drive gear 2444. The first linkage rack 2441 is fixedly mounted on the first frame 212. The first linkage gear 2442 meshes with the first linkage rack 2441. The first auxiliary gear 2443 is rotatably mounted on the first auxiliary plate 2112 of the first sliding component 211 and coaxially arranged with the first linkage gear 2442. The first drive gear 2444 is coaxially connected to the first shaft 24311 and is connected to the first auxiliary gear 2443 via a first synchronous toothed belt 2445.

[0108] In this way, during the movement of the cutting blade 232, the first linkage gear 2442 rotates due to meshing with the first linkage rack 2441. The rotation of the first linkage gear 2442 drives the first auxiliary gear 2443 to rotate. The first auxiliary gear 2443 drives the first drive gear 2444 to rotate through the first synchronous toothed belt 2445, thereby driving the first shaft 24311 to rotate. The rotation of the first shaft 24311 drives the second shaft 24312 to rotate and drives the first grinding roller 241 to rotate, thereby achieving the grinding and deburring of the vertical cutting surface of the cutting board 30 while cutting.

[0109] Please refer to the following: Figure 4 , Figure 7 and Figure 8 To facilitate the installation of the second grinding roller 242, the grinding module 24 also includes a second mounting component 245. The second mounting component 245 includes a second mounting shaft 2451 and a second connecting shaft 2452. One end of the second grinding roller 242 is embedded in the second mounting shaft 2451, the second mounting shaft 2451 is rotatably connected to the second frame 222, and the other end of the second grinding roller 242 is rotatably mounted on the second connecting shaft 2452. The second connecting shaft 2452 is fixedly connected to the first sliding component 211.

[0110] With this configuration, the second grinding roller 242 is provided with a second mounting shaft 2451 and a second connecting shaft 2452 at both ends, which makes the rotation of the second grinding roller 242 smooth, thereby ensuring that the grinding process of the board 30 is stable and reliable.

[0111] In some embodiments, the second mounting shaft 2451 includes a third shaft body 24511 and a fourth shaft body 24512. The bottom end of the third shaft body 24511 is provided with a second slide rod 24513, and the top end of the fourth shaft body 24512 is provided with a second slide groove 24514 for the second slide rod 24513 to slide. The two sides of the bottom end of the second slide rod 24513 are slidably provided with second locking blocks 24515. The side wall of the bottom end of the second slide rod 24513 is provided with a second receiving groove 24516 for the second locking blocks 24515 to slide. The inner walls of the two sides of the second slide groove 24514 are provided with second locking grooves 24517 for the corresponding second locking blocks 24515 to extend into. The second receiving groove 24516 is provided with a second spring 24518, which is used to make the second locking blocks 24515 slide toward the corresponding second locking groove 24517.

[0112] It can be seen that the second spring 24518 is used to provide elastic force to the second locking block 24515 so that the second locking block 24515 tends to extend into the corresponding second locking groove 24517.

[0113] Furthermore, a second crossbar 2421 is fixedly connected to the top of the second grinding roller 242, and a second cross groove 245121 is provided at the bottom of the fourth shaft 24512 for the second crossbar 2421 to extend into. In this way, when the third shaft 24511 rotates, it drives the fourth shaft 24512 to rotate via the second slide bar 24513; and when the fourth shaft 24512 rotates, it drives the second grinding roller 242 to rotate via the second crossbar 2421.

[0114] To facilitate the connection between the second grinding roller 242 and the second connecting shaft 2452, a second limiting block 2422 is provided on both sides of the bottom end of the second grinding roller 242. The top end of the second connecting shaft 2452 is provided with a second rotating groove 24521 for the second grinding roller 242 to rotate and a second limiting groove 24522 for the second limiting block 2422 to pass through. The inner wall of the bottom end of the second rotating groove 24521 is provided with a second annular groove 24523 for the second limiting block 2422 to rotate, so that the second grinding roller 242 and the second connecting shaft 2452 are rotatably connected.

[0115] With this configuration, both ends of the second grinding roller 242 are limited axially. When installing the second grinding roller 242, the second limiting block 2422 of the second grinding roller 242 is inserted into the second limiting groove 24522 of the second connecting shaft 2452. Then, the second cross bar 2421 is aligned with the second cross groove 245121, and the fourth shaft 24512 is pulled downward to allow the second cross bar 2421 to enter the second cross groove 245121. At this time, the second locking block 24515 automatically enters the second locking block under the action of the second spring 24518. The second grinding roller 242 is quickly fixed within the groove 24517. When the second grinding roller 242 needs to be disassembled, first press the second locking block 24515 inward to disengage it from the second locking groove 24517. Then slide the fourth shaft 24512 upward to disengage the second cross bar 2421 from the second cross groove 245121. After that, rotate the second grinding roller 242 so that the second limiting block 2422 is aligned with the second limiting groove 24522 to disengage the second grinding roller 242 from the second connecting shaft 2452.

[0116] To facilitate the linkage of the second grinding roller 242, the grinding module 24 also includes a second linkage component 246, which includes a second linkage rack 2461 and a second linkage gear 2462. The second linkage rack 2461 is fixedly mounted on the second frame 222, and its tooth surfaces are inclined. The second linkage gear 2462 is coaxially connected to the third shaft 24511 and meshes with the second linkage rack 2461.

[0117] During the movement of the cutting blade 232, the second linkage gear 2462 rotates due to meshing with the second linkage rack 2461. The rotation of the second linkage gear 2462 drives the third shaft 24511 to rotate, which in turn drives the fourth shaft 24512 to rotate and the second grinding roller 242 to rotate. Thus, while cutting, the diagonal corners of the cut plate 30 are ground and deburred.

[0118] In some embodiments, a detection component for the grinding degree of the board 30 can also be provided on the second transfer module 22. The detection component can be a vision component, which includes a bracket and a camera movably mounted on the bracket. The bracket can be mounted on the second transfer module 22, and the camera is positioned facing the board 30. In this way, the camera can be used to acquire an image of the cut surface of the board 30 after cutting and grinding. At the same time, the board processing device also includes a control component, which is communicatively connected to the detection component.

[0119] With this setup, the image processing technology of the control component can be used to inspect the surface of the polished board 30. By acquiring and cutting images of the polished board 30, and then preprocessing and analyzing the images, it can be determined whether there are defects, such as burrs, over-polished depressions, or under-polished protrusions. This method can improve the efficiency and accuracy of inspection and reduce manual intervention.

[0120] In addition, corresponding prompting components can be set up. After the first board 30 is cut and polished, the cutting and polishing surface of the board 30 can be inspected by the detection component. If polishing defects are found, the prompting module can issue a corresponding prompt to remind the on-site staff to check the installation accuracy of the polishing roller. If necessary, the polishing roller can be replaced in time.

[0121] In summary, by using the first grinding roller 241 and the two second grinding rollers 242, the cutting surface and side corners can be ground and deburred simultaneously with the cutting blade 232 cutting the plate 30, eliminating the need for an additional grinding and deburring process and improving processing efficiency. Furthermore, after a period of use, the first grinding roller 241 and the second grinding roller 242 are easy to replace, simplifying the replacement operation and ensuring effective deburring.

[0122] In some embodiments, please continue to refer to the appendix. Figure 1 The workbench 10 includes a base plate 11, a support plate 12, and a support frame 13.

[0123] The support plate 12 is mounted on the base plate 11 and is used to support the plate clip 30. The support plate 12 has a clearance groove 121 in the middle for the cutting blade 232 to pass through. The support frame 13 is mounted on the base plate 11 and has an abutment rod 14 that is raised and lowered on the top plate 131 of the support frame 13. The abutment rod 14 is threadedly connected to the top plate 131 and is used to abut against the plate clip 30 to fix the plate clip 30 to the support plate 12.

[0124] With this configuration, the base plate 11, support plate 12, and top plate 131 are arranged sequentially along the Z-axis (second direction). The support plate 12 supports the plate 30, meaning the plate 30 is located between the support plate 12 and the top plate 131. The abutment rod 14, which is threadedly connected to the top plate 131, abuts against the plate 30, thereby ensuring that the relative position of the plate 30 and the support plate 12 is fixed, preventing the plate 30 from moving relative to the support plate 12, and ensuring reliable processing of the plate 30.
