This welding production line occupies a large space; for single-station welding or double-station welding structures; the welding production line of this assembly line has high construction costs, occupies a large space, and has structural redundancy; and the welding on the production line can only be flat welding, the position of the objects to be welded is relatively fixed, and the structure of the objects to be welded sometimes hinders the welding angle, so multiple welding robotic arms can only be added; therefore, for simple product welding, it is necessary to build an intelligent, low-cost, small-space, and convenient welding production line.

[0003] Generally, a single-sided support welding production line adopts a three-station design. However, the length of the entire conveyor belt is fixed.
