[0049] Preferably, a detection camera 15 is also provided on the fixing plate 14;

[0050] The detection camera 15 is located on one side of the lifting mechanism 12.

[0051] Preferably, a first limiting groove 16 is provided at the bottom of the first movable plate 2;

[0052] The top of the second movable plate 3 is provided with a second limiting groove 17;

[0053] The upper end of the elastic element 18 is located within the first limiting groove 16;

[0054] The lower end of the elastic element 18 is located within the second limiting groove 17.

[0055] Preferably, the elastic element 18 is located at the top of the clamping fixture 9;

[0056] The top of the cavity 8 has an opening that is connected to the pressure port 10.

[0057] Preferably, the width of the housing 7 is greater than the width of the clamping fixture 9.

[0058] The working principle of this utility model:

[0059] In this embodiment, the elastic element 18 is selected as a compression spring. The elastic element 18 is sleeved on the clamping fixture 9, and the compression spring is wound around the clamping fixture 9. The center of the winding path of the elastic element 18 is coaxial with the center of the clamping fixture 9. The compression spring is coaxial with the clamping fixture 9. The elastic element 18 deforms as the clamping fixture 9 moves up and down, providing elastic force.

[0060] Specifically, the box 7 has a hollow polyhedral structure such as a cuboid or cube with vertical and horizontal connections. The top of the box 7 has an opening. The bottom of the cavity 8 is connected to the lower pressing port 10 of the clamping fixture 9 through the first through groove 19. The clamping fixture 9 has a tubular structure with a central through-hole to ensure that the clamping fixture 9 is vertically connected and meets the welding requirements. The lower pressing port 10 of the clamping fixture 9 is wider at the top and narrower at the bottom.

[0061] The support plate 1 is connected to the lifting end of the lifting mechanism 12. The lifting mechanism 12 can be a linear module. The lifting end of the lifting mechanism 12 can cause the support plate 1 to move up and down, thereby driving the clamping fixture 9 to move up and down. The air outlet of the dust removal air knife 13 is inclined and can face the top opening of the box 7 for blowing dust. It is connected to the dust extraction unit through the dust extraction pipe 11 for dust extraction. In this embodiment, the dust extraction pipe 11 is connected to the cavity 8 to extract the dust particles, pollutants, and polluting gases after welding. The guide shaft 6 can move up and down along the bushing 5 to ensure the linear accuracy of the clamping fixture 9 relative to the first movable plate 2.

[0062] In this embodiment, the top portion of the clamping fixture 9 passes through the first through groove 19. A first limiting groove 16 and a second limiting groove 17 are provided to limit the position of the compression spring. When the clamping fixture 9 presses down, the top portion of the clamping fixture 9 extends into the first through groove 19, compressing the spring. At this time, the pressure sensor 4 receives the elastic force from the first movable plate 2, thereby accurately detecting the downward pressure and avoiding errors in the detected pressure value due to tilting of the clamping mechanism. The detection camera 15 can be a positioning camera or a detection camera 15 used to detect defects in nickel sheets, achieving integrated detection and welding. It is integratedly installed via the fixing plate 14, reducing the need for repositioning steps. In this embodiment, the inner diameter of the first through groove 19 is larger than the outer diameter of the clamping fixture 9. This embodiment can be applied to laser nickel sheet welding processes.
