Automatic welding method for large reinforcing mesh based on AI vision

The automatic welding method comprises a working platform and an industrial personal computer, the working platform comprises a guide rail and a machine base moving along the guide rail, a supporting arm is rotationally arranged on the machine base, a robot is arranged on the supporting arm in a sliding mode, a welding gun and a second visual device are arranged on the robot, and the industrial personal computer is connected with the welding gun. A first vision device is arranged on the supporting arm, the working platform further comprises an operation table arranged below the robot, and the method further comprises the following steps of three-dimensional template building, reinforcing mesh laying, first-time initial positioning, fine positioning, turning over, second-time initial positioning and fine positioning. Compared with the prior art, preliminary positioning of the reinforcing mesh is completed through the first vision device, then the positioning precision of the reinforcing mesh is improved throug
