Description

Technical Field

[0001] The invention relates to the technical field of dust cleaning, and in particular to a dust cleaning device for a PCB board. Background Art

[0002] PCB, or printed circuit board, is an indispensable and important component of electronic equipment. It forms electrical connections between electronic components by laying conductive copper foil patterned on insulating materials. The main functions of PCB include providing electrical connections, mechanical support and circuit protection for electronic components.

[0003] In the process of producing and processing PCB boards, since the PCB boards are directly exposed to the air, a large amount of dust in the air will fall on the PCB boards and is difficult to clean. In addition, since the main body of the PCB board needs to be drilled during production, the debris and dust generated during the drilling process are easily embedded in the holes, which is difficult to be completely cleaned by ordinary vacuuming or blowing. After cleaning, the collected dust needs to be disassembled and processed, which is very inconvenient. Therefore, we propose a dust cleaning device for PCB boards. Summary of the invention

[0036] Start the fan 301. When the PCB board body 2 enters the bottom of the U-shaped frame 302, air and dust enter the interior of the cavity 306 through the air suction port 604, the air suction pipe 603, and the connecting pipe 601, and are discharged after being filtered by the filter 311, while the debris and dust remain under the filter 311.

[0037] When it is necessary to clean the dust inside the cavity 306, close the solenoid valve 602, open the second door panel 307, pinch the handle 305 and pull it to one side, so that the first connecting rod 308 drives the second cleaning brush 309 to move to one side, rubs the filter 311, and pushes out the dust inside the holes of the filter 311 to prevent the filter 311 from being blocked. When the handle 305 moves, the second connecting rod 312 drives the scraper 304 to move to one side, thereby scraping the dust out of the second door panel 307.
