The servo motor 17 is started, and the worm 15 is driven to rotate through the power shaft 20, and then the worm gear 16 is driven to rotate, so that the transmission shaft 4 drives the PCB board to perform a smooth 180° flip. Then, start the reciprocating motor 21 in the displacement component again. Through the cooperation of the lead screw 22 and the threaded through hole of the moving member 3, the reverse displacement of the moving member 3 is realized, so as to drive the PCB board to reset and enter the dispensing station. After the dispensing is completed, finally pull out the PCB board. The above steps are carried out in a cycle until all PCB boards are processed.
