[0026] Through such a design, the distance between the distance sensor 4 and the extension plate 3 is detected, and the vibration of the driving motor amplifies the extension plate 3, which is convenient for the detection of the distance sensor 4.
[0027] Furthermore, a buffer compression spring 5 is provided between the extension plate 3 and the distance sensor 4 .
[0028] Through such a design, when the vibration amplitude of the driving motor is too large, the buffer compression spring 5 can play a buffering role in order to protect the distance sensor 4.
[0029] Specifically, the driving assembly includes a first driving assembly for driving the welding gun 2 to move along the X-axis direction.
[0030] Specifically, the first driving assembly includes an X-axis column 6 and a first movable plate 7 slidably connected to the X-axis column 6, the X-axis column 6 is fixedly provided with a first rack 8, the extension direction of the first rack 8 is parallel to the axial direction of the X-axis, the first movable plate 7 is rotatably provided with a first gear 9 meshing with the first rack 8, and the first movable plate 7 is fixedly provided with a first motor 10 for driving the first gear 9 to rotate.
[0031] With such a design, the first motor 10 drives the first gear 9 to rotate, and since the X-axis column 6 is fixed, the first movable plate 7 performs sliding motion, thereby realizing the movement of the welding gun 2 in the X-axis direction.

[0038] Furthermore, the X-axis column 6 , the Y-axis column 11 and the Z-axis column 16 are all provided with limiting protrusions 20 .
[0039] This design can prevent the first movable plate 7, the second movable plate 12, and the Z-axis column from moving beyond the rack and falling off.
[0040] Furthermore, a counterweight block 21 is fixedly disposed on the Y-axis column 11 , and the counterweight block 21 and the second movable plate 12 are respectively disposed on two sides of the Y-axis column 11 .
[0041] Through this design, the weight balance of the Y-axis column is achieved to prevent one side from tipping over due to excessive weight.
