Under the cooperation of the rotating shaft and the rotating mounting plate, the rotating support frame drives the metal guardrail to rotate 180 degrees. Then, the welding robot can be used to perform welding processing on the other side of the metal guardrail to realize the double-sided automatic welding processing of the metal guardrail. Finally, after the welding process is completed, the driving motor is controlled to start working. With the cooperation of the rotating shaft and the rotating mounting plate, the rotating support frame drives the metal guardrail to rotate 180 degrees. The metal guardrail is above the rotating support frame. Driven by the moving mechanism, the first feeding assembly is moved to the top of the metal guardrail. Then the first lifting device is controlled to drive the lifting support mounting plate to descend, so that the bottom of the first suction plate and the second suction plate are in contact with the top of the metal guardrail. Then all the second electromagnets are controlled to stop working, and all the first electromagnets are controlled to start working to adsorb the metal guardrail. Then, the first lifting device is controlled to drive the lifting support mounting plate to rise, so that the metal guardrail that has been welded follows the rise, and then with the cooperation of the moving mechanism, the metal guardrail adsorbed on the first feeding assembly is driven to move to the top of the second conveyor belt conveying mechanism, and the first lifting device is controlled to drive the lifting support mounting plate to descend, so that the bottom of the metal guardrail contacts the conveyor belt at the top of the second conveyor belt conveying mechanism. At the same time, all the first electromagnets are controlled to stop working, and the metal guardrail that has been welded is transported to the next process for processing through the second conveyor belt conveying mechanism, completing the automatic unloading operation of the metal guardrail welding process.
