The positioning mechanism 2 adjusts the spacing between the three clamping claws 6 according to the size of the product 39 and secures the product 39 in place using the three clamping claws 6. The robot 3 then drives the welding gun 4 to weld the product 39. After the welding gun 4 is disassembled for maintenance and repair, it is controlled to move to the calibration mechanism 5, which automatically compensates for the weld point.

[0036] The product 39 described in this embodiment is a compressor.

[0037] The transfer mechanism 1 is an existing product. The technical application and usage instructions of the transfer mechanism 1 are very mature and complete, and its related structure will not be described in detail in this article.

[0038] A positioning block 7 is provided on the top side of each clamping claw 6. The three clamping claws 6 are respectively set on the welding table 8 through a movable limiting mechanism. A spacing adjustment mechanism is provided below the welding table 8. The three clamping claws 6 pass through the welding table 8 and are connected to the spacing adjustment mechanism.

[0039] The movable limiting mechanism is composed of a slide rail 9 and a slider. The slide rail 9 is arranged on the welding table 8 . The slider is connected to the clamping claw 6 . The slider is arranged on the slide rail 9 .

[0040] The spacing adjustment mechanism includes a turntable 10, a bevel gear set, and a motor 11. The turntable 10 is arranged on the bottom side of the welding table 8 through a rotating shaft 12.

[0047] The reference orifice plate 34 is made of transparent PVC material.

[0048] When performing automatic compensation of weld spots, after the welding gun 4 is disassembled for maintenance and repair, the robot 3 drives the welding gun 4 to move to the shearing mechanism to automatically shear the welding wire. At this time, the welding wire tip after standard shearing is used as a reference, and then the robot 3 drives the welding gun 4 with the welding wire to move to the calibration hole 36. At this time, the position difference between the welding wire tip and the core base column 35 is visually confirmed, and the compensation value is set according to the position difference between the two. The compensation value is input on the touch screen, and the robot 3 is controlled to move according to the compensation value.
