[0075] During the pressing process, the first linear module 91 drives the second linear module 92 to move, and the second linear module 92 can drive the connecting plate 93 to move. Since the slide plate 94 is slidably connected to the connecting plate 93, when the nozzle 97 presses the workpiece to be welded, the slide plate 94 will slide under force.

[0081] Specifically, a solenoid valve island 15 is provided on the back plate 2 for controlling the protection air flow;

[0082] Of course, the solenoid valve island 15 is also used for controlling the suction air flow of the dust removal pipe 98 or other air circuit control work.

[0087] Specific implementation steps:

[0088] During operation, the entire welding device is driven by the robot for displacement adjustment;

[0089] Among them, the rangefinder 74 in the ranging component 7 realizes position adjustment through the sliding of the slider 72 and the displacement of the slide table cylinder 73;

[0090] In the CCD component 8, by rotating the screw 83, the camera base 82 and the camera 84 are driven for displacement adjustment;

[0091] In the welding component 9, displacement adjustment is performed through the first linear module 91 and the second linear module 92, and through the sliding of the slide plate 94 and the elasticity of the spring 96, the adaptive displacement adjustment of the nozzle 97 is realized to avoid overpressure;

[0092] During welding, the nozzle 97 is pressed against the workpiece to be welded, the welding laser is output by the laser vibration lens 6, at the same time, the dust removal pipe 98 is connected to the induced draft fan for air flow suction, and the air knife 10 is connected to the air compressor for air flow blowing; in this way, the welding dust can be removed by relying on the dust removal pipe 98, and the air knife 10 can blow away the welding spatter to protect the lens of the laser vibration lens 6.
