[0039] Working principle and usage process of this utility model: After stacking the PCBs with holes aligned, they are placed on the placement platform 8. During placement, since the top of the positioning pin 17 is frustum-shaped with a small top and a large bottom, it is only necessary to ensure that each PCB is roughly positioned, not precisely. In this state, the graphics on each PCB are not precisely aligned. After placement, the second motor 11 is started, which drives the drive wheel 12 to rotate. Through the transmission of the belt 15, the driven wheel 14 can be rotated, which in turn drives the second ball screw 13 to rotate. Since the middle of the lifting plate 16 is engaged with the second ball screw 13 through the second nut 20, the lifting plate 16 can be moved upward, causing the positioning pin 17 to move upward, so that the positioning pin 17 passes through the positioning holes of each PCB that has been placed, thus achieving precise positioning of the graphics on each PCB. Then the first motor 2 is started. The first motor 2 drives the transmission shaft 3 to rotate through the belt transmission assembly 4. Since the two ends of the transmission shaft 3 are fixedly sleeved with the bottom end of the belt transmission assembly 4, the first ball screw 6 can be driven to rotate, thereby driving the first nut 7 meshing on the surface of the first ball screw 6 to move upward, and then driving the PCB placed on the placement table 8 to move upward into the lamination equipment.
