Then, during the welding process, the drive box 3 on the mounting seat 2 works, and the drive shaft of the drive box 3 controls the rotation of the rotating seat 4, driving the placement frame 5 to rotate, so that the robot body 1 can weld the material more quickly.

[0032] Since the welding process will emit dazzling welding light, if no protection is taken, it will not only affect the office environment of the entire workshop, but also cause safety hazards when people pass by or cross the workshop.

[0033] The angle adjustment motor 33 is started, and its driving shaft controls the rotation of the angle adjustment gear 34.
