While welding the workpiece on the second welding table 39, the staff places the unwelded workpiece on the first welding table 38. When the welding of the workpiece on the second welding table 39 is completed, the motor 330 is started, and the motor 330 drives the transmission rod 320 to rotate, the transmission rod 320 drives the bevel gear 310 to rotate, the bevel gear 310 drives the second rotating rod 35 to rotate, the second rotating rod 35 drives the second gear 33 and the second half gear 34 to rotate, and the second half gear 34 drives the tooth plate 36 to move during the rotation, and the tooth plate 36 drives the moving seat 37 to move. The moving seat 37 drives the first welding station 38 and the second welding station 39 to move. When the first welding station 38 and the second welding station 39 are moving, the second gear 33 drives the first gear 31 to rotate in the opposite direction, the first gear 31 drives the first rotating rod 3 to rotate in the opposite direction, and the first rotating rod 3 drives the first half gear 32 to rotate in the opposite direction. When the first welding station 38 moves to the welding position of the welding gun 12 and the robot arm 11, the second welding station 39 moves to the position of one of the high-power fans 4. At this time, the second half gear 34 is out of contact with the tooth plate 36, and the first half gear 32 is meshed with the tooth plate 36. The motor 330 is turned off, and the welding gun 12 and the robot arm 11 weld the workpiece on the first welding station 38. When the welding gun 12 and the robot arm 11 are in contact with each other, the second half gear 34 is out of contact with the tooth plate 36, and the first half gear 32 is meshed with the tooth plate 36. The motor 330 is turned off, and the welding gun 12 and the robot arm 11 weld the workpiece on the first welding station 38. While the workpiece on the first welding station 38 is being welded, the staff removes the welded workpiece on the second welding station 39, and starts one of the high-power fans 4 to clean the welding slag on the second welding station 39. After the second welding station 39 is cleaned, the workpiece that has not been welded is placed on the second welding station 39. At this time, the welding gun 12 and the robot arm 11 also complete the welding of the workpiece on the first welding station 38. Then, the motor 330 is started again, and the motor 330 drives the transmission rod 320 to rotate, the transmission rod 320 drives the bevel gear 310 to rotate, the bevel gear 310 drives the second rotating rod 35 to rotate, the second rotating rod 35 drives the second gear 33 and the second half gear 34 to rotate, and the second gear 33 drives the first gear 31 to rotate in the opposite direction.

When the second welding table 39 moves to the welding position of the welding gun 12 and the robot arm 11, the first welding table 38 also moves to the position of another high-power fan 4. At this time, the first half gear 32 is out of contact with the tooth plate 36, and the second half gear 34 is engaged with the tooth plate 36. The motor 330 is turned off, and the welding gun 12 and the robot arm 11 weld the workpiece on the second welding table 39. When the welding gun 12 and the robot arm 11 weld the workpiece on the second welding table 39,The staff removes the workpiece on the first welding table 38, starts another high-power fan 4 to clean the welding slag on the first welding table 38, and then places the workpiece that has not been welded on the first welding table 38, and repeats the operation.
