[0025] Specifically, the operation of the two conveying rollers 2 is supported by the workbench 1, and the two sets of conveying rollers 2 are driven to operate by an external power source. The workpiece to be welded is moved by the two conveying rollers 2 operating respectively. The U-shaped plate 5 is fixed by the workbench 1 to provide a stable environment for the U-shaped plate 5. The linear slide rail one 8, the linear slide rail two 12, the sliding block one 9 and the sliding block two 13 are driven to operate by an external power source. The linear slide rail two 12 is supported by the U-shaped plate 5 to facilitate the operation of the sliding block two 13. The sliding block two 13 can only operate horizontally inside the U-shaped plate 5 due to the protrusions on the left and right sides of the sliding block two 13, which can prevent the linear slide rail two 12 and the sliding block two 13 from deforming due to long-term operation of the equipment below. The linear slide rail one 8 and the sliding block one 9 thereon are supported by the workbench 1. The welding gun 17 is moved by the reciprocating air cylinder 11 below the sliding block two 13 and above the sliding block one 9, so that the welding position of the workpiece can be adjusted according to the thickness.
