[0037] Please refer to the attached figure in the instruction manual Figure 1 , support plates 2 are installed at both ends of the bottom of the horizontal plate 10, and the first screw rod 11 is rotatably connected between the support plates 2 through bearings. A servo motor 9 for driving the first screw rod 11 to rotate is installed on the outer side of the right end support plate 2. The outer wall of the first screw rod 11 is threadedly connected with a first nut 13. A sliding assembly 12 is arranged between the first nut 13 and the horizontal plate 10.

A slide groove 1201 is provided at the bottom of the horizontal plate 10, and the slide groove 1201 and the slider 1202 are slidably connected. When the first nut 13 moves left and right, it can drive the slider 1202 to slide in the slide groove 1201, so that the first nut 13 can be limited to prevent the first nut 13 from rotating. A second electric push rod 8 is installed at the bottom of the first nut 13, and a laser welding head 20 is installed at the output end of the second electric push rod 8.

[0038] Working principle: When using the laser welding machine, the staff pulls up the pull plate 2206, and the pull plate 2206 drives the second pressure plate 2203 to move upward through the movable rod 2205 and compresses the positioning spring 2204. Then, the pressure switch to be welded is placed in the first clamping seat 1806 and the second clamping seat 2201 respectively. Then the staff releases the pull plate 2206, and under the elastic force of the positioning spring 2204, the second pressure plate 2203 moves downward to press the pressure switch. At the same time, the staff manually rotates the turntable 1801, and the rotation of the turntable 1801 drives the screw 1804 to rotate. Under the limiting action of the guide rod 1802 and the guide hole 1803, the rotation of the screw 1804 drives the first pressure plate 1805 to move downward, so that the pressure switch can be pressed by the first pressure plate 1805, which is convenient for the welding machine to clamp and fix pressure switches of different specifications.

[0039] Then, the servo motor 9 is started through the controller. When the servo motor 9 is working, it drives the first screw rod 11 to rotate. The first screw rod 11 rotates to drive the first nut 13 to move left and right. When the first nut 13 moves, it drives the slider 1202 to slide in the slide groove 1201, so that the first nut 13 can be limited. When the first nut 13 moves, it drives the second electric push rod 8 and the laser welding head 20 to move left and right, so as to facilitate the adjustment of the lateral position of the laser welding head 20. Then, the forward and reverse motor 14 is started. When the forward and reverse motor 14 is working, it drives the second screw rod 16 to rotate. The second screw rod 16 rotates to drive the second nut 15 to move. The movement of the second nut 15 drives the cross plate 10 to move. When the cross plate 10 moves, it drives the limit sleeve 1703 to slide along the limit rod 1702, so that the cross plate 10 can be limited. The movement of the cross plate 10 drives the second electric push rod 8 and the laser welding head 20 to move back and forth, so as to adjust the longitudinal position of the laser welding head 20.

[0040] When the position of the laser welding head 20 is adjusted to the docking point of the pressure switch, the second electric push rod 8 is controlled to extend, and the second electric push rod 8 extends to drive the laser welding head 20 to move downward to weld the pressure switch. During the welding process, the driving motor 703 is started by the controller. When the driving motor 703 is working, it drives the driving gear 701 to rotate through the driving shaft 702. The driving gear 701 rotates and drives the driven gear 704 to rotate. The driven gear 704 rotates and drives the driven shaft 705 to rotate, so that the first electric push rod 3 can be driven to rotate. The rotation of the first electric push rod 3 drives the pressure switch to rotate, and then the flip welding of the pressure switch is completed, thereby increasing the welding efficiency of the laser welding machine.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
