The use of robotic operations can reduce the labor intensity of operators and improve the automation level of production equipment. At the same time, it can improve the product quality of the enterprise and enhance the overall competitiveness of the enterprise. Stud welding is a method of contacting one end of the stud with the surface of the plate, energizing the arc, and applying a certain pressure to the stud after the contact surface melts to complete the welding. In the process of automobile production, studs need to be welded on the surface of its accessories to facilitate the fixed positioning between accessories.

Specifically, the automobile accessory plate is adsorbed by the vacuum suction cup 2. When the point that needs to be adsorbed affects the welding point, the motor 5 works, the motor 5 drives the gear 4 to rotate, the gear 4 drives the rack 6 to move, and the rack 6 drives the extension plate 7 to adjust the position of the corresponding vacuum suction cup 2 to avoid the adsorption point from affecting the welding point of the automobile accessory plate. In this way, the position of the adsorption point can be adjusted according to the actual welding point position of the automobile accessory plate to avoid the position of the adsorption point from affecting the welding point.

[0022] In this embodiment, an adjusting screw 8 is threaded through one side of the extension plate 7, and the adjusting screw 8 is rotatably connected to an L-shaped mounting plate 9 at one end toward the center of the support plate 1. A knob 10 is fixedly connected to the side of the adjusting screw 8 away from the L-shaped mounting plate 9, and several vacuum suction cups 2 are respectively mounted on the outer surfaces of several L-shaped mounting plates 9. Specifically, according to different sizes of automobile accessory plates, before clamping them, the knob 10 can be rotated, and the knob 10 drives the adjusting screw 8 to rotate, and the adjusting screw 8 drives the L-shaped mounting plate 9 to move, thereby adjusting the position of the vacuum suction cup 2, and adjusting the vacuum suction cup 2 to a position as close as possible to the edge of the automobile accessory plate, thereby preventing the vacuum suction cup 2 from obstructing the subsequent welding of the welding gun.
