[0022] As Figure 1 and 2 shown, an adjustable laser welding air knife protection device of the present application is composed of an adjustment bracket 1, a first adjustment hole 2, a second adjustment hole 3, a third adjustment hole 4, an air knife mechanism 5, a mounting plate 50, a connecting plate 51, an air knife protection cover 52, a wind force transmission hole 53, a stabilizing plate 6, etc.;

[0023] When the equipment for compressed air starts to operate, the air flow sheet is blown out through the air knife provided in the air knife protection cover 52. The air outlet of the air knife is set to be slender, which is more conducive to the concentration of the wind direction, keeping the welding slag generated around the laser welding clean and tidy without damaging the laser welding lens. The material of the air knife is aluminum alloy or stainless steel. The aluminum alloy has a longer service life than other products after electroplating, and the stainless steel air knife can be used in high-temperature and corrosive environments. The whole equipment is designed with "full air flow" and blows out along with the width of the air knife.

[0024] There are two adjustment brackets 1 in the equipment and they are spaced apart. The two adjustment brackets 1 are provided with a bearing platform extending outwards and are used in combination with the stabilizing plate 6 in the mechanism to make the whole mechanism more stable. The adjustment bracket 1 is provided with a first adjustment hole 2, a second adjustment hole 3 and a third adjustment hole 4. The first adjustment hole 2 and the second adjustment hole 3 are located above the third adjustment hole 4.

The mounting plates 50 are vertically welded to both sides behind the connecting plate 51. The air knife protection cover 52 is connected to the front of the connecting plate 51 by screws. Wind force transmission holes 53 are provided at the connection positions of the connecting plate 51 and the air knife protection cover 52, and the two wind force transmission holes 53 overlap. The compressed air in the equipment is transported to the air knife through a wind force pipeline, and the wind force pipeline passes through the wind force transmission hole 53 to connect to the air knife. Three mounting holes are provided on the mounting plate 50. The mounting holes of the mounting plate 50 are respectively movably connected to the first adjustment hole 2, the second adjustment hole 3 and the third adjustment hole 4. The mounting plate 50 rotates through the first adjustment hole 2 and adjusts the direction through the second adjustment hole 3 and the third adjustment hole 4.
