Then the rotating motor starts at this time, driving the clamping cylinder to rotate and drive the shell to rotate. Welding is performed through the electric welding assembly, and the position of the electric welding assembly is adjusted by driving the electric cylinder. After welding is completed, the shell is output through the shell conveyor belt.

[0016] 1. In the present invention, the cover plate is guided by the guide frame and conveyed to the cover plate clamping frame. The torsion springs on both sides push the rotating shaft to drive the cover plate to move to the bottom of the connecting plate. Then the suction cup abuts against the top of the cover plate to adsorb the cover plate. Then the shell rises to receive the cover plate, and the cover plate and the shell are quickly and accurately positioned. The cover plate and the shell only need to be placed on the conveyor belt to automatically guide and position them without manual operation, which greatly increases the welding accuracy.
