A welding platform 20 is fixedly connected to one end of the cylinder 21. A gas control valve 22 is arranged on one side of the table 1. The vertical plate 2 is arranged perpendicular to the table 1. One end of the protective shell 5 penetrates and slides in the vertical plate 2. The first driven gear 8 is rotatably connected in the protective shell 5. There are two groups of the first driven gears 8 and they are symmetrically distributed on both sides of the first driving gear 7. One end of the second lead screw 9 is rotatably connected in the protective shell 5. The guide rod 11 slidably penetrates through the moving plate 10. There are two groups of the guide rods 11 and they are symmetrically distributed on both sides of the moving plate 10. The laser positioning assembly 15 is located directly above the welding head 14. The second driven gear 18 is rotatably connected to the moving plate 10. There are two groups of the second driven gears 18 and they are symmetrically distributed on both sides of the second driving gear 17. The brush disk 19 is higher than the welding head 14. There are four groups of the cylinders 21 and they are evenly distributed under the welding platform 20. The gas control valve 22 is connected to the four groups of cylinders 21. Controllers are provided on the first driving motor 3, the second driving motor 6, and the fixed block 12. The laser positioning assembly 15, the gas control valve 22, and the controller are all electrically connected. In the present utility model, devices such as the controller, the welding head 14, the laser positioning assembly 15, and the gas control valve 22 are part of the prior art and have not been modified or improved. Their working principles and structures are well-known in the relevant field, so they will not be described in detail here.

[0030] Working principle: During use, the staff place the product to be welded on the welding platform 20, and then use the laser positioning component 15 to scan the workpiece to be welded currently. Then, the sampled signal after scanning is processed and transmitted to the welding robot control system. Then, the signal system calculates the coordinates of the workpiece to be welded currently based on the obtained signal. Then, by comparing with the position information of the reference workpiece, the weld track of the workpiece to be welded currently is corrected. Control the gas control valve 22 to adjust the support height of the cylinder 21, control the first drive motor 3 to rotate to drive the first lead screw 4 to rotate to adjust the horizontal lateral position of the protective shell 5, control the second drive motor 6 to drive the first driving gear 7, drive two groups of first driven gears 8 through the first driving gear 7 to drive the second lead screw 9, and smoothly push the moving plate 10 in the protective shell 5 under the guidance of the guide rod 11 through the rotation of the second lead screw 9, so as to adjust the horizontal longitudinal position of the welding head 14. Adjust the height of the welding head 14 in the vertical direction by controlling the telescopic movement of the electric telescopic rod 13. During the welding process, the protective shell 5 blocks the strong light of laser welding to prevent welding light pollution. Through the control of the above series of controllers, the welding head 14 can move in all directions. During the laser welding process, the welding head 14 can be raised above the brush disc 19 by retracting the electric telescopic rod 13. Then, start the third drive motor 16 to drive the second driving gear 17, drive the second driven gear 18 to rotate through the second driving gear 17, drive the brush disc 19 through the second driven gear 18, and brush the welding area through the rotation of the brush disc 19 to reduce the interference of pollutants on the welding effect. Through the positioning control in the above aspects, the stringent requirements for welding jigs are significantly reduced, and the flexible adaptability and compatibility of the welding system are greatly enhanced. It not only effectively reduces the design and manufacturing costs of the jig, but also greatly shortens the time cycle for processing welding. At the same time, non-contact operation is realized, and there is no need for manual touch of the workpiece. Thus, while ensuring efficient operation, the safety and reliability of the operation are further improved, and the operation steps of the staff are reduced.
