The rotary motor 22 drives the rotating mesh box 14 to rotate, rinsing it. After rinsing, the electric push rod 6 extends to the right, moving the rotating mesh box 14 into the main chamber 1 and opening the electric door, causing the PCB board to fall out. The PCB board falls between the rotating tube 16 and the feeding plate 18. At this time, the high-frequency transducer generates a directional ultrasonic beam to clean the PCB board. The hot air blower 9 introduces hot air into the vertical tube 19 and the rotating tube 16 through the first L-shaped tube 21 and the second L-shaped tube 23, respectively, and sprays it out through the first jet hole 17 and the second jet hole 20, so that it can perform multi-position auxiliary drying, thereby enabling it to be effectively dried and improving its drying efficiency and utilization efficiency.
