Driven by the driving motor 8, the brush 10 can rotate on the surface of the PCB board, that is, the PCB board placed in the placement groove 5 is cleaned. During the cleaning process, the mobile frame will drive the brush 10 to move on the surface of the PCB board, thereby cleaning various positions of the PCB board to ensure a comprehensive cleaning process.
