[0002] During the production and processing of PCB boards, some dust particles will accumulate on the board surface. If they are not cleaned, the processing accuracy will be affected, resulting in a large number of defects. Since PCB boards cannot be exposed to water, it is obviously unreasonable to use brushing to clean them.

[0003] A board surface cleaning device for PCB circuit board production and processing in the prior art (publication number: CN217664850U) is provided with a placement plate, a corner bracket, a positioning rod and a knob. When the PCB board needs to be cleaned, the corner brackets at the four corners are used to limit the PCB board to avoid movement when the PCB board is cleaned. However, the device cannot collect dust in time during the cleaning process, which easily causes secondary contamination of the cleaned side PCB board, and the cleaning effect is poor. Therefore, it is urgent to design a board surface cleaning device for PCB circuit board production and processing with better cleaning effect. Utility Model Content

[0023] Please see attached Figure 1 -Attached Figure 4A board surface cleaning device for PCB circuit board production and processing includes a support base 1 and a vacuum cleaner 8. A dust cleaning box 2 is fixedly installed on the top of the support base 1. The top and one side of the dust cleaning box 2 are open structures. A clamping mechanism and a dust cleaning component are arranged in the dust cleaning box 2. The dust cleaning component includes a return tube 12 and a slider 13. The return tube 12 and the slider 13 are both slidably installed in the dust cleaning box 2. A plurality of blowing holes are opened on the inner ring surface of the return tube 12. Two telescopic air pipes 17 for pumping compressed air are arranged on one side of the return tube 12. The clamping mechanism carries the material through the middle of the return tube 12. An electromagnet 19 is fixedly installed on one side of the return tube 12 and the slider 13. The dust cleaning box 2 is provided with an ash discharge port 11 at one side of the bottom, a dust collector 8 is fixedly installed at the bottom of the ash cleaning box 2, and the dust suction port is connected to the ash discharge port 11, a transparent cover plate 3 is fixedly installed on the top of the ash cleaning box 2, two air flow valves 4 are fixedly installed on one side of the ash cleaning box 2, a slider 13 and the surface of the ash cleaning box 2 are provided with round holes, two telescopic air pipes 17 are connected with the inside of the return pipe 12 at one end, and the other end passes through the corresponding round holes and is connected with the two air flow valves 4, two return springs 14 are fixedly installed on one side of the slider 13, and the other ends of the two return springs 14 are fixedly installed on the inner wall of the ash cleaning box 2, and a battery 16 and a controller 15 for an electromagnet 19 are also fixedly installed on one side of the slider 13.

[0024] When in use, the air compressor is connected through the air pipe, so that the compressed air can be pumped into the return pipe 12 through the air flow valve 4, and the dust is blown on the surface of the PCB board through the return pipe 12. The electromagnetic properties of the electromagnet 19 on the surface of the return pipe 12 are controlled by the controller 15 to change intermittently. With the help of the electromagnetic adsorption principle, the return pipe 12 is driven to slide back and forth in the dust cleaning box 2, so as to expand the coverage of the dust cleaning, make the dust cleaning more thorough, and improve the dust cleaning effect of the equipment. Then, the dust blown away is sucked away by the vacuum cleaner 8 to prevent the dust from floating on the cleaned PCB board surface, thereby further improving the dust cleaning effect of the equipment.

[0025] In this embodiment, the clamping mechanism includes a push-pull plate 5, and two guide columns 9 are symmetrically fixedly installed on one side of the push-pull plate 5 near the cleaning box 2. A slide groove is also provided on one side of the push-pull plate 5, and two storage rods 10 are symmetrically slidably installed in the slide groove. A two-way screw rod 18 is rotatably installed in the slide groove, and the two-way screw rod 18 passes through the outer surfaces of the two storage rods 10 and is respectively threadedly connected thereto. The two storage rods 10 are both L-shaped structures. A handwheel 6 is rotatably installed on one end of the push-pull plate 5, and one side of the handwheel 6 is fixedly installed through a connecting shaft and a rotation center of one end of the two-way screw rod 18. Two circular groove blind holes matching the guide columns 9 are provided on one side of the cleaning box 2, and the two guide columns 9 are respectively slidably installed in the two circular groove blind holes. A limit sleeve 7 is fixedly installed on one side of the cleaning box 2, and a groove matching the handwheel 6 is provided on one side of the limit sleeve 7, and a bolt is threadedly connected to the surface of the limit sleeve 7.

[0026] When in use, the PCB board is placed between the two placement rods 10, and then the handwheel 6 is rotated to drive the bidirectional screw rod 18 to rotate, and then the two placement rods 10 are synchronously driven to slide towards each other and clamp the PCB board, and then the push-pull plate 5 with the PCB board is pushed into the cleaning box 2, so that the PCB board passes through the return tube 12, and one end of the two placement rods 10 presses against the slider 13 and compresses the reset spring 14. After the handwheel 6 is embedded in the limit sleeve 7, the bolt on the surface of the limit sleeve 7 is tightened against the outer surface of the handwheel 6 to achieve locking of the clamping mechanism, thereby improving the stability of the equipment during use.

[0027] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: when in use, by changing the magnetic properties of the electromagnet 19, according to the principle that like charges repel and opposite charges attract, the return tube 12 is driven to slide back and forth relative to the slider 13, so that the return tube 12 can clean the upper and lower surfaces of the entire PCB board, and the cleaning effect is better;

[0028] Various types of PCB boards can be clamped and fixed by the clamping mechanism, and then pushed into the cleaning box 2 for cleaning. The hand wheel 6 is limited by the limit sleeve 7, which further makes the cleaning process of the equipment more stable, avoiding the PCB board being blown around by compressed air during the cleaning process, affecting the cleaning effect.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
