[0019] Example 1:

[0020] A laser welding wire feeding mechanism, referring to Figure 1 、 Figure 3 and Figure 4 , including an operating table 1 and a wire feeding assembly. A servo motor 2 is fixedly connected to the surface of the operating table 1. The output end of the servo motor 2 is fixedly connected to a screw rod 3 through a coupling. The external thread of the screw rod 3 is connected to a lifting tube 4. The rotation of the screw rod 3 can drive the lifting tube 4 outside it to move up and down. A movable plate 5 is fixedly connected to the top of the lifting tube 4. Two second vertical plates 6 are fixedly connected to the surface of the movable plate 5. Two guide shafts 7 are connected between the two second vertical plates 6 for rotation up and down. The welding wire passes through the gap between the two guide shafts 7. An electric telescopic rod 8 is fixedly connected to the surface of the movable plate 5. The output end of the electric telescopic rod 8 is fixedly connected to a first lifting block 9. One side of the first lifting block 9 is rotatably connected to a tensioning rod 10. The tensioning rod 10 is used to adjust the tension of the welding wire.

[0021] Reference Figure 3 The wire feeding assembly includes two first vertical plates 11 fixedly connected to the surface of the operating table 1, and a wire feeding roller 12 is rotatably connected between the two first vertical plates 11. The wire feeding roller 12 is electrically connected to an external driving device, and the driving device can drive the wire feeding roller 12 to work.

[0022] Reference Figure 1 and Figure 2 Connecting ears 13 are installed at the four corners of the movable plate 5. The inside of the four connecting ears 13 is slidably connected to the first limiting rod 14. The bottom of the first limiting rod 14 is fixedly connected to the surface of the movable plate 5. When the movable plate 5 is raised or lowered, the four connecting ears 13 will also slide on the outside of the four first limiting rods 14 respectively.

[0023] Reference Figure 2 and Figure 3 The end of the tensioning rod 10 away from the first lifting block 9 is rotatably connected to the second lifting block 15, and the second lifting block 15 is slidably connected to the inside of the second limiting rod 16. The bottom end of the second limiting rod 16 is fixedly connected to the surface of the movable plate 5. The second lifting block 15 can also provide support for the tensioning rod 10 when sliding outside the second limiting rod 16, which can increase the stability of the electric telescopic rod 8 when driving the tensioning rod 10 to rise and fall.

[0024] Reference Figure 1 Support legs 17 are installed at the four corners of the bottom of the operating table 1, and the four support legs 17 can support the entire mechanism.

[0025] The implementation principle of a laser welding wire feeding mechanism in the embodiment of the present application is as follows: the servo motor 2 is preferably HBS57 type, the electric telescopic rod 8 is preferably LX600 type, the servo motor 2 and the electric telescopic rod 8 are both electrically connected to the external power supply through a switch, the wire feeding roller 12 is electrically connected to the external driving device, and the driving device can drive the wire feeding roller 12 to work, and the outside of the wire feeding roller 12 is wound with welding wire, which passes through the gap between the two guide shafts 7 and fits tightly with the upper arc surface of the tensioning rod 10. The servo motor 2 is started by the switch, and the servo motor 2 drives the screw rod 3 to rotate. The rotation of the screw rod 3 will drive the lifting tube 4 outside it to rise and fall, and the movement of the lifting tube 4 will drive the movable plate 5 to rise and fall. When the movable plate 5 is lifted When lowering, the four connecting ears 13 will also slide respectively on the outside of the four first limit rods 14, thereby increasing the stability of the movable plate 5 when lifting and lowering, thereby adjusting the delivery height of the wire feeding mechanism, which can be suitable for different wire feeding needs. The electric telescopic rod 8 is started by the switch, and the electric telescopic rod 8 starts to drive the first lifting block 9 to rise. The rise of the first lifting block 9 drives the tensioning rod 10 to adjust the height. At this time, the second lifting block 15 will also slide on the outside of the second limit rod 16. The second lifting block 15 can increase the stability of the electric telescopic rod 8 when driving the tensioning rod 10 to rise and fall. Therefore, the tensioning force of the tensioning rod 10 on the welding wire can be adjusted, so that the tensioning force can be adjusted during the wire feeding process, thereby improving the wire feeding effect of the welding wire.
