[0052] When the photocells are welded, the starting motor drives the reciprocating screw to rotate, and the rotation of the reciprocating screw drives the moving block to move along the reciprocating screw and the guide rod, thereby driving the welding head at the bottom of the moving block to move along the weld between the photocells, thereby welding the photocells.
