[0033] refer to Figure 3The left end of the support block 7 is fixedly connected with an extension plate 9, so that the support block 7 can drive the extension plate 9 to move during the movement. The through holes on both sides of the extension plate 9 are slidably connected with sliding columns 10, so that the extension plate 9 can limit the sliding columns 10. The outer sleeve of the sliding column 10 is provided with a spring 11. The bottom of the two sliding columns 10 is fixedly connected with a frame 12. The frame 12 is supported by the sliding column 10. One end of the spring 11 is fixedly connected to one side of the extension plate 9, and the other end of the spring 11 is fixedly connected to one side of the frame 12. When the sliding column 10 slides at the through hole of the extension plate 9, the extension plate 9 can be extended. The distance between the plate 9 and the frame 12 is close so that the spring 11 is squeezed to generate elastic potential energy. The inner wall of the frame 12 is rotatably connected to two rotating wheels 13. The external coupling of the two rotating wheels 13 is connected to a belt 14. The rotating wheels 13 are driven by the frame 12 so that the belt 14 is pressed against the PCB board. At this time, the spring 11 is squeezed, which can not only improve the cutting stability, but also provide buffering force and improve the cutting efficiency. The top of the sliding column 10 is fixedly connected to a limiting block 15, and the bottom of the limiting block 15 is in contact with the top of the extension plate 9, so that the limiting block 15 can support the sliding column 10.

[0034] refer to Figure 2 The bottom of the slider 5 is fixedly connected with a limiting component, which includes a limiting plate 16. The top of the limiting plate 16 is fixedly connected to the bottom of the slider 5. The limiting plate 16 is stabilized by the slider 5. The through holes on both sides of the limiting plate 16 are slidably connected with limiting columns 17. The bottom of the limiting column 17 is fixedly connected to the top of the support block 7, so that the support block 7 can drive the limiting column 17 when moving, thereby improving the stability of the limiting column 17 during the movement.

[0035] refer to Figure 4, both sides of the right end of the support block 7 are provided with disassembly components, and the disassembly components include two control rods 18, and the two control rods 18 are respectively slidably connected to the two sides of the right end of the support block 7. The cutting knife 8 can be controlled to be disassembled by sliding the control rods 18. The bottom of the control rod 18 is fixedly connected with a sliding plate 19. When the control rod 18 moves, it can drive the sliding plate 19 to move. The outside of the sliding plate 19 is slidably connected to the inner wall of the support block 7. Springs 20 are provided inside both sides of the support block 7. One end of the spring 20 is fixedly connected to the inner wall of one side of the support block 7. The spring 20 The other end is fixedly connected to one side of the sliding plate 19, so that the sliding plate 19 can squeeze the spring 20 when moving. The bottom sides of the support block 7 are slidably connected with connecting blocks 21. The outside of the control rod 18 is engaged with the through hole of the connecting block 21. The bottom of the connecting block 21 is fixedly connected to the top of the cutting knife 8. The connecting block 21 is fixed by the control rod 18, so that the cutting knife 8 can be fixed. The external thread of the control rod 18 is connected with a nut 22. The left end of the nut 22 is in contact with the right end of the support block 7. The control rod 18 can be stabilized by the nut 22.

[0036] refer to Figure 2 A collecting component is fixedly connected to the bottom inner wall of the shell 1, and the collecting component includes a collecting box 23. The bottom of the collecting box 23 is fixedly connected to the bottom inner wall of the shell 1. The front end of the collecting box 23 is slidably connected to a drawer 24, and the impurity particles generated during the cutting process of the PCB board are collected through the drawer 24. The top of the collecting box 23 is fixedly connected to a fan 25, and the input end of the fan 25 is fixedly connected to a suction pipe 26. The suction pipe 26 can generate suction by starting the fan 25. The other end of the suction pipe 26 is fixedly connected to a suction head 27, and the rear end of the suction head 27 is fixedly connected to the rear end inner wall of the shell 1. The suction pipe 26 generates suction, so that the suction head 27 generates suction, thereby sucking the impurity particles on the top of the conveyor belt 3, and finally causing the particles to fall into the drawer 24.

[0037] Working principle: when the device is needed, the PDB board is transported through the conveyor belt 3. When it reaches the appropriate position, the hydraulic cylinder 6 is started. When the hydraulic cylinder 6 is started, the support block 7 can be driven to move, so that the cutting knife 8 can be pushed to move for cutting during the movement of the support block 7. Before cutting, the extension plate 9 will first drive the sliding column 10 to push the frame 12, so that the frame 12 pushes the rotating wheel 13 to drive the belt 14 to move, so that the belt 14 is against the PCB board. At this time, the distance between the frame 12 and the extension plate 9 is constantly reduced, so that the spring 11 is squeezed and deformed, and finally the cutting knife 8 cuts the PCB board again, which can not only stabilize the PCB board during the cutting process, but also provide buffering force to achieve integrated cutting without additional clamping, thereby improving the cutting efficiency.

[0038] During the cutting process, the fan 25 is started to generate suction in the suction tube 26, and finally the suction head 27 generates suction to absorb the foreign particles on the surface of the conveyor belt 3 due to cutting, so that the particles enter the drawer 24 and are collected, thereby preventing the foreign particles from affecting the cutting.

[0039] When the cutting knife 8 needs to be replaced, the slide rail 4 is started to make the slider 5 slide on the bottom of the slide rail 4. The sliding of the slider 5 can drive the hydraulic cylinder 6, so that the support block 7 drives the cutting knife 8 to slide at the front end of the housing 1. At this time, the nut 22 is unscrewed, and the control rod 18 is pressed. When the control rod 18 is pressed, the control rod 18 can be withdrawn from the through hole of the connecting block 21, so that the cutting knife 8 can be disassembled. When it needs to be installed, the control rod 18 is pressed, and the connecting block 21 is inserted into the bottom of the supporting block 7. When the control rod 18 is released, the spring 20 will rebound to push the sliding plate 19. When the sliding plate 19 is pushed, the control rod 18 can be driven to reset, thereby engaging the connecting block 21 and completing the fixing of the cutting knife 8, thereby ensuring that the cutting quality is always maintained in the best state and avoiding inaccurate cutting or quality degradation caused by tool wear or damage.
