[0008] The beneficial effects of the utility model are as follows: the utility model clamps the cathode frame by pneumatic clamps, and presses it by a clamping mechanism, and then feeds the material by a feeding mechanism, and the material is loaded by a loading device, and the welding robot performs fully automatic welding. After welding is completed, the cathode frame is driven forward by a driving mechanism, and the next welding position is moved to the welding station to perform welding at the next position. The device realizes automated welding with high work efficiency. The operator does not directly face the welding operation, which greatly reduces the hazards of occupational diseases.
