Among them, the actuator 5 includes but is not limited to a cylinder.

[0024] In one embodiment, the mounting bracket 2 includes a top plate 21 and guide posts 22, which are arranged in the circumference of the top plate 21 and connected to the workbench 1. The driving block 3 is arranged on the guide posts 22, and the guide posts 22 are used to guide the vertical movement of the driving block 3. Preferably, a thread is arranged at the lower end of the guide post 22, and a matching limiting nut 23 is arranged on the guide post 22. The position of the limiting nut 23 on the guide post 22 is used to limit the limit position of the downward movement of the driving block 3, thereby controlling the spacing between the two moving blocks 4.

[0025] In one embodiment, if Figure 1-4 As shown, a trapezoidal groove is concavely formed on the lower surface of the driving block 3, and the moving block 4 is slidably connected to the two inclined surfaces of the trapezoidal groove.

[0026] In one embodiment, if Figure 1-4As shown, a square guide groove 31 and an adjustment hole 32 penetrating the bottom plate of the square guide groove 31 are respectively vertically arranged at both ends of the driving block 3, an adjustment screw 61 is extended upwardly from the upper surface of the pressing block 6, a spring 62 is arranged on the adjustment screw 61, the pressing block 6 is slidably arranged in the square guide groove 31, and the adjustment screw 61 passes through the adjustment hole 32 and is connected to the adjustment nut 63. The square guide groove 31 is used to guide the pressing block 6 to move up and down, and a spring 62 is arranged between the pressing block 6 and the square guide groove 31 to prevent the pressing block 6 from hard contact with the welding strip.

[0027] In one embodiment, if Figure 1-4 As shown, the opposite surfaces of the two moving blocks 4 are provided with positioning portions 41, and the positioning portions 41 are vertical planes.

Then the actuator 5 drives the driving block 3 to move down to the limit nut 23; at this time, the positioning parts 41 of the two moving blocks 4 are attached to the two sides of the welding strip, and the pressing block 6 is pressed on the upper surface of the two ends of the welding strip, and the black ink is sprayed on the surface of the welding strip by the sprayer 7. Since the pressing block 6 and the positioning part 41 block the two ends of the side and upper surface of the welding strip, only the upper surface of the welding strip is sprayed. After the spraying is completed, the actuator 5 is reset, and the welding strip is driven to move to the next spraying position by the traction device.
