[0023] Working principle:

[0024] During the working process, after the PCB board is placed on the conveyor belt 41, the conveyor belt starts to operate, transporting the PCB board from the equipment entrance to multiple processing stages such as cleaning, rinsing, and drying. The conveyor belt ensures that the PCB board can move continuously and smoothly, avoiding movement deviation during the cleaning process. When the PCB board passes through the cleaning component 44, the connecting pipe 4401 and the cleaning head 4402 start to work. The cleaning head 4402 can spray the cleaning liquid on the PCB board, and the cleaning rod 4403 contacts the surface of the PCB board to remove dust, impurities, and minor contaminants on the surface. According to the thickness of the PCB board and the cleaning requirements, the distance between the cleaning head 4402 and the PCB board is adjusted to ensure the effectiveness of cleaning. The placement rod 4404 and the limit post 4405 fix the position of the cleaning rod to prevent the cleaning head 4402 from deviating from the set position during the cleaning process. When the PCB board passes through the rinsing device 42, the rinsing head 4204 in the rinsing pipe 4203 starts to work, and the rinsing head 4204 precisely sprays onto the surface of the PCB board. The detector 4208 monitors the rinsing effect in real time to ensure that every part of the PCB board has been thoroughly cleaned. The cover body 4201 is used to cover and protect the rinsing device 42 to prevent external contamination from affecting the rinsing process. After the PCB board is rinsed, since there is still residual moisture on the surface, it will continue to move to the drying device 43. The steering rod 4302 in the drying device 43 adjusts the direction of the drying head 4303 so that it can cover all areas of the PCB board. The drying head 4303 efficiently dries the PCB board to ensure that the moisture on the board is quickly evaporated, avoiding affecting subsequent operations due to moisture residue. The entire cleaning device is housed in the box body 1, and the box body 1 is used to protect all internal components of the device, prevent the influence of the external environment, and provide a stable structural support platform. The bracket 2 ensures that the water tank 3 and the processing device 4 maintain a stable structural position.
