Referring to Figure 1 , it mainly includes a laser welding device 1. The laser welding device 1 includes a laser seat 101 and a laser head 102 provided at the bottom of the laser seat 101. A lifting cylinder 2 is fixedly installed on the upper part of the laser seat 101. The output shaft of the lifting cylinder 2 is connected to a protection component 3, and the lifting cylinder 2 can drive the protection component 3 to lift and lower.

[0017] Refer to Figure 1 , the protection component 3 includes a smoke collecting plate 301, an air hood 302, and a blowing ring 303. The smoke collecting plate 301 is slidably connected to the laser base 101 of the laser welding device 1. The air hood 302 is connected to the lower end of the smoke collecting plate 301, and the blowing ring 303 is connected to the lower end of the air hood 302.

[0018] For the specific structure of the protection component 3, refer to Figure 2 , Figure 3 , where the smoke collecting plate 301 includes a substrate 301a with an opening in the middle. The substrate 301a is sleeved and installed on the laser base 101 through the opening. The output shaft of the lifting cylinder 2 is fixedly connected to the substrate 301a. A number of air extraction holes 301b are provided at the bottom of the substrate 301a, and the air extraction holes 301b are arranged at equal angles around the center of the substrate 301a. An air collecting cavity 301c communicating with the air extraction holes 301b and a through cavity 301d communicating with the top of the air collecting cavity 301c are provided inside the substrate 301a. An air extraction plate 301e communicating with the through cavity 301d is also connected to the top of the substrate 301a, and an air extraction pipe 301f is connected to the top of the air extraction plate 301e.

[0019] The air hood 302 includes an inner hood body 302a and an outer hood body 302b, and a cavity 302c is formed between the inner hood body 302a and the outer hood body 302b. The top of the air hood 302 is connected to the bottom end of the substrate 301a, and the top of the cavity 302c is closed by the substrate 301a.
