The four motors 20, the first support rod 15, the second support rod 17, and the third support rod 18 work together to weld the diagonally joined pads. Then, the positioning mechanism is reset, and the first cylinder 13 remains stationary. At this point, the second motor 10 is turned on, which drives the second gear 12 through the first gear 11 to rotate, thereby driving the lower robotic arm to rotate. Then, with the cooperation of the third motor 16, the fourth motor 20, the first support rod 15, the second support rod 17, and the third support rod 18, the remaining positions are welded. After welding is completed, the pads are allowed to cool down, the pads are removed, the device is reset, and finally the power is turned off.
