[0032] After placing the circuit board on the support plate 609, the movement of the cylinder 601 can be controlled. When the cylinder 601 moves, it will pull the push plate 604 closer to each other through the push rod 603. At this time, the push plate 604 will move on the slide rail 607 through the slider 606, so that personnel can limit and fix it according to the size of the circuit board, thereby improving the practicality of the equipment.

[0033] like Figure 4 and Figure 5As shown, the clamping mechanism 6 includes a cylinder 601, a fixed shell 602, a push rod 603, a push plate 604, a spring 605, a slider 606, a slide rail 607, a connecting block 608 and a support plate 609.

[0034] Control motor 401 to rotate, motor 401 will drive worm wheel 403 to rotate through worm 402, at this time worm wheel 403 will drive transmission rod 404 to rotate, thereafter transmission rod 404 will drive lifting plate to move up and down through connecting rod 405, at this time, support plate 609 can be placed inside cleaning box 8, and lifting mechanism 4 can make it more convenient for personnel to take and place circuit boards, and at the same time, it can also prevent cleaning liquid from splashing during cleaning, thereby reducing the difficulty of operation for personnel.

After that, the motor 401 can be controlled to rotate. The motor 401 will drive the worm wheel 403 to rotate through the worm 402. At this time, the worm wheel 403 will drive the transmission rod 404 to rotate , after which the transmission rod 404 will drive the lifting plate to move up and down through the connecting rod 405. At this time, the support plate 609 can be placed inside the cleaning box 8. The lifting mechanism 4 can make it more convenient for personnel to take and place the circuit board. At the same time, it can also prevent the cleaning liquid from splashing during the cleaning process, thereby reducing the difficulty of personnel operation. After that, the water pump 702 can be controlled to extract the cleaning liquid inside the water tank 701, and then the circuit board is cleaned by the nozzle 703.
