[0004] As can be seen from the above-mentioned edge grinding device for circuit board processing, the existing technology has the following problems: it is inconvenient to clamp and fix circuit boards of different sizes, which causes certain inconvenience to the grinding of their edges and corners. At the same time, the debris will fly everywhere during grinding, which is inconvenient for subsequent cleaning and reduces work efficiency. Therefore, we need to propose a debris collection device for circuit board processing. Summary of the Invention

[0005] The purpose of this utility model is to provide a chip collection device for circuit board processing, which can effectively prevent chip splashing during processing, further reduce the tediousness of cleaning and maintenance, improve work efficiency, and can conveniently clamp and fix circuit boards of different sizes, effectively ensuring the stability of clamping, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides: a chip collection device for circuit board processing, comprising a processing table, a discharge trough on the top of the processing table, a collection box movably installed below the discharge trough, a grinding disc for processing circuit boards above the discharge trough, and a chip protection and collection assembly on the outer side of the grinding disc; an adjusting rod installed on one side of the discharge trough, a bearing plate movably connected to the surface of the adjusting rod, a locking assembly for positioning the circuit board on the surface of the bearing plate, and a gear connected to one end of the double-ended screw of the locking assembly; and a mounting bracket installed on one side of the bearing plate, the interior of which is provided with an anti-detachment assembly that engages with the gear for locking.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the coordinated arrangement of a processing table, a discharge chute, and a debris protection and collection component, allows the grinding disc driven by a grinding motor to trim the edges of the circuit board. The anti-splash cover can block the debris generated by the grinding disc. Large debris particles fall into the collection box below with the discharge chute. At the same time, the fan unit embedded in the mounting frame can blow away the fine debris and dust, which can be sucked up with the suction head of an external dust collection device, thus improving the debris collection effect.

[0015] 2. This utility model utilizes a combination of adjusting rods, a support plate, a mounting bracket, a locking assembly, and an anti-loosening assembly. During processing, the circuit board is placed on top of the support plate. By rotating the knob at the end of the double-ended screw, the positioning clamp and connecting block move towards the circuit board and clamp it. Simultaneously, rotating the locking rod presses the protective sleeve at the bottom of the limiting plate onto the circuit board, further improving the circuit board's fixation. After adjustment, the compression spring inside the mounting bracket acts on the baffle, pushing the arc-shaped clamp at one end of the connecting rod onto the gear surface, locking the double-ended screw of the connecting gear to prevent loosening. This allows for convenient control of the circuit board on the support plate to move towards the grinding disc for edge grinding operations via the adjusting rod. Attached Figure Description

The fan unit 7 can be folded through the mounting frame 6 to reduce the space occupied. The fan unit 7 blows and cleans the dust and debris generated by the edge grinding. The dust suction head 8 is a structure that works with the fan unit 7 to collect debris, reducing dust pollution in the processing workshop.

[0026] The bottom of the processing table 1 is equipped with limit guide rails 10 on both sides of the discharge trough 2. The two sides of the collection box 11 are slidably connected to the surfaces of the limit guide rails 10. The lower part of the adjusting rod 12 is provided with a groove communicating with the discharge trough 2, which can push the incoming debris into the collection box 11 during the movement of the moving block 13, ensuring the stability of operation. The bottom of the support plate 14 is connected to the moving block 13, which is movably installed on the surface of the adjusting rod 12. The surface of the processing table 1 is equipped with a grinding motor 3, and the output end of the grinding motor 3 is connected to the grinding disc 4. The limit guide rails 10 are the structure for limiting the assembly of the collection box 11, and the adjusting rod 12 is the control structure for the movement of the moving block 13, which facilitates the control of the back and forth movement of the support plate 14 to move the circuit board toward the grinding disc 4 for grinding operation.

[0027] The locking assembly includes a connecting block 16 movably mounted on the surface of the double-ended screw 15, and a positioning clamping plate 17 connected to the surface of the connecting block 16; wherein, a locking rod 18 is movably mounted on the top of the positioning clamping plate 17, and a limiting plate 19 is connected to the bottom of the locking rod 18.

The arc-shaped clamping plate 26 is a toothed plate that cooperates with the gear 21 to fix the position of the double-headed screw 15 after adjustment and prevent loosening. The compression spring 23 cooperates with the baffle 25 to keep the arc-shaped clamping plate 26 engaged with the gear 21.

[0031] During processing, the circuit board is placed on top of the support plate 14. By rotating the knob at the end of the double-headed screw 15, the positioning clamp 17 moves and clamps the circuit board in conjunction with the connecting block 16. In addition, the locking rod 18 rotates to press the protective sleeve 20 at the bottom of the limiting plate 19 onto the circuit board, which can further improve the fixing effect of the circuit board. After adjustment, the compression spring 23 inside the mounting bracket 22 acts on the baffle 25 to push the arc-shaped clamp 26 at one end of the connecting rod 24 onto the surface of the gear 21, which locks the double-headed screw 15 of the connecting gear 21 to prevent loosening. The circuit board on the support plate 14 can then be easily moved towards the grinding disc 4 for edge grinding by adjusting the rod 12.

[0032] When the grinding motor 3 drives the grinding disc 4 to grind and trim the circuit board, the anti-splash cover 5 can block the debris generated by the grinding disc 4. Large debris falls into the collection box 11 below with the discharge chute 2. At the same time, the fan unit 7 embedded in the mounting frame 6 can blow away the fine debris and dust, which can be sucked up with the suction head 8 of the external vacuum cleaner to improve the debris collection effect.
