[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-3 , the utility model provides an embodiment: a PCB circuit board dust removal device for electronic technology, including a workbench 1, two fixed blocks 3 are fixedly connected to the front side of the top of the workbench 1, the left end of the left fixed block 3 is fixedly connected to a motor 2, the bottom end of the motor 2 is fixedly connected to the top of the workbench 1, and the driving end of the motor 2 is fixedly connected to a bidirectional threaded rod 4, the outer wall of the bidirectional threaded rod 4 is rotatably connected to the inner wall of the fixed block 3, and the left and right sides of the outer wall of the bidirectional threaded rod 4 are threadedly connected to sliders 5, the bottom ends of the sliders 5 are slidably connected to the top of the workbench 1, the opposite ends of the sliders 5 are fixedly connected to connecting rods 17, and the opposite ends of the connecting rods 17 are fixedly connected to clamping blocks 8;

[0025] Specifically, the circuit board is placed in the groove on the clamp block 8 on one side, and the motor 2 is started to drive the bidirectional threaded rod 4 to rotate so that the slider 5 on the bidirectional threaded rod 4 moves relative to the top of the workbench 1, so that the groove on the clamp block 8 on the other side contacts the circuit board to fix the circuit board, so that the device can clamp and fix circuit boards of different sizes for easy cleaning.

[0026] The bottom end of the workbench 1 is fixedly connected to a motor 2 16, and the driving end of the motor 2 16 is fixedly connected to a one-way threaded rod 6, the outer wall of the one-way threaded rod 6 is rotatably connected to the inner wall of the workbench 1, the outer wall of the one-way threaded rod 6 is threadedly connected to a brush 7, and the inner wall of the brush 7 is slidably connected to a slide rod 13, and the bottom end of the slide rod 13 is fixedly connected to the top of the left fixed block 3, and the rear end of the workbench 1 is fixedly connected to a dust box 12, and a fan 14 is penetrated through the rear end of the dust box 12, and the bottom end of the fan 14 is fixedly connected to the rear side of the top of the workbench 1, and a box door 15 is provided at the right end of the dust box 12, and a collection pipe 11 is penetrated through the top of the dust box 12, and the other end of the collection pipe 11 is fixedly connected to a dust hood 9, and the rear end of the dust hood 9 is fixedly connected to a support block 10, and the bottom end of the support block 10 is fixedly connected to the middle of the top of the workbench 1;

[0027] Specifically, after the circuit board is fixed, the starting motor 16 drives the one-way threaded rod 6 to rotate with the cooperation of the slide rod 13, so that the brush 7 can move up and down on the one-way threaded rod 6 to clean and remove dust from the circuit board. During the dust removal process, the fan 14 generates a negative pressure inside the dust box 12, and the collection pipe 11 and the dust hood 9 cooperate to suck the dust generated by the cleaning into the dust box 12 for collection. Then the dust inside the dust box 12 can be cleaned by opening the box door 15. Since the circuit board is vertically fixed on the clamping block 8, the dust on both sides of the circuit board generated by the cleaning of the brush 7 will not be blocked by the circuit board, and can be directly collected by the dust hood 9 on the top of the circuit board, thereby solving the problem of some dust residue accumulating on the top of the workbench 1.

[0028] Working principle: put the circuit board into the groove on the clamp block 8 on one side, start the motor 1 2 to drive the bidirectional threaded rod 4 to rotate so that the slider 5 on the bidirectional threaded rod 4 moves relative to the top of the workbench 1, so that the groove on the clamp block 8 on the other side contacts the circuit board to fix the circuit board, so that the device can clamp and fix circuit boards of different sizes for easy cleaning. After the circuit board is fixed, start the motor 2 16 to drive the unidirectional threaded rod 6 to rotate. With the cooperation of the slide bar 13, the brush 7 can move up and down on the unidirectional threaded rod 6 to clean the circuit board. The dust collecting box 12 is cleaned and dust removed. During the dust removal process, negative pressure is generated inside the dust collecting box 12 through the fan 14, and the dust generated by cleaning is sucked into the dust collecting box 12 for collection in cooperation with the collection pipe 11 and the dust collecting hood 9. Then the dust inside the dust collecting box 12 can be cleaned by opening the box door 15. Since the circuit board is vertically fixed on the clamping block 8, the dust generated by the cleaning of the two sides of the circuit board by the brush 7 will not be blocked by the circuit board, and can be directly collected by the dust collecting hood 9 on the top of the circuit board, thereby solving the problem of some dust residue accumulating on the top of the workbench 1.
