[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0020] See also Figure 1The embodiment of the present application provides an automatic dust removal line for laser welding, including an air purification component and a dust suction channel. The air purification component is used to purify the dust-laden air, and the dust suction channel includes a main channel 1 and a branch channel 4. The outlet of the main channel 1 is connected to the inlet of the air purification component. The main channel 1 includes a plurality of segments 2. Along the axial direction of the main channel 1, from the side of the main channel 1 close to the air purification component to the side away from the air purification component, the caliber of each segment 2 gradually decreases. The outlet of the branch channel 4 is connected to the segment 2 one by one, and the inlets of the main channel 1 and the branch channel 4 are respectively provided with dust suction hoods 6.

[0021] The dust suction passage is used to convey the dust-laden air sucked from the dust suction hood 6 .

[0022] The main channel 1 includes a plurality of segments 2, and the diameter of each segment 2 gradually decreases from the side of the main channel 1 close to the air purification component to the side away from the air purification component. On the one hand, the manufacturing cost of the main channel 1 is saved. On the other hand, from the entrance to the exit of the main channel 1, as the number of branch channels 4 increases, the diameter of the main channel 1 gradually increases, ensuring that the air conveying capacity of the main channel 1 meets the requirements. On the other hand, the segment 2 at the entrance of the main channel 1 can be used as a branch channel 4, further reducing the cost.

[0023] The structure of the dust hood 6 is well known to those skilled in the art and will not be described in detail here.

[0024] The dust hood 6 can effectively increase the dust collection area, thereby increasing the dust removal effect.

[0025] In the embodiment of the present application, a fan may also be included. The fan is arranged at the outlet end of the air purification component. Under the action of the fan, negative pressure can be generated in the main channel 1, so that the dust hood 6 can suck in dusty air.

[0026] The multiple branch channels 4 enable the dust suction channel to perform dust suction operations on multiple welding stations 7 at the same time, thereby reducing production costs.

[0027] Dust-laden air is sucked in through the dust hood 6, transported through the branch channel 4 and the main channel 1, and then enters the air purification component, where it is purified and then discharged, thereby achieving the purpose of dust removal operation for the welding station 7.

[0028] In some embodiments, the air purification component includes a demister 9 .

[0029] The demister 9 can intercept liquid droplets and solid particles in the air, so that dust in the air can be removed.

[0030] The structure and working principle of the demister 9 are well known to those skilled in the art and will not be described in detail here.

[0031] In some embodiments, the air purification component further includes an electrostatic precipitator 10 , which is disposed in front of the demister 9 along the air flow direction.

[0032] The electrostatic precipitator 10 can effectively filter out particulate matter in the air, thereby increasing the air purification effect.

[0033] The structure and working principle of the electrostatic precipitator 10 are well known to those skilled in the art and will not be described in detail here.

[0034] In some embodiments, a plurality of demisters 9 are provided, and the plurality of demisters 9 are arranged in parallel.

[0035] A plurality of demisters 9 can increase the purification effect on the air, and because a plurality of demisters 9 are arranged in parallel, when one of the demisters 9 is damaged, the remaining demisters 9 can continue to work, thereby increasing the working reliability of the dust removal system.

[0036] For example, the main channel 1 may be provided with a plurality of outlets, each outlet being connected to an inlet of the demister 9 respectively, so that a plurality of demisters 9 may be arranged in parallel.

[0037] In some embodiments, two adjacent segments 2 are connected via a frustum-shaped channel 3 , wherein the small diameter side of the frustum-shaped channel 3 is connected to the smaller diameter of the two adjacent segments 2 , and the large diameter side is connected to the larger diameter.

[0038] On the one hand, the calibers of the two segments 2 connected thereto can be inconsistent. On the other hand, the caliber of the truncated cone-shaped channel 3 gradually increases from the small diameter side to the large diameter side, thereby improving the air circulation effect.

[0039] In some embodiments, the branch channel 4 is connected to the frustum-shaped channel 3 .

[0040] On the one hand, the axial length of the frustum-shaped channel 3 is short, so the branch channel 4 is connected to the segment 2 through the frustum-shaped channel 3, which is convenient for processing. On the other hand, the risk of opening the segment 2 and reducing the sealing effect of the segment 2 is reduced.

[0041] In some embodiments, the branch channel 4 includes a connecting section 5 , which is connected to the frustum-shaped channel 3 , and along the air flow direction, the connecting section 5 is inclined toward the rear side of the segment 2 .

[0042] The branch channel 4 may include a dust suction section and a connecting section 5 , and the dust suction section and the connecting section 5 are bent to facilitate the arrangement of the dust suction hood 6 .

[0043] Along the air circulation direction, the connecting section 5 is inclined toward the rear side of the segment 2, so that the angle between the air circulation direction from the branch channel 4 into the main channel 1 and the air circulation direction in the main channel 1 is less than 90 degrees, thereby increasing the air circulation effect.

[0044] In some embodiments, the dust collection channel also includes a parallel channel 8, the outlet of the parallel channel 8 is connected to the inlet of the air purification component, the outlet of the main channel 1 is connected to the inlet of the parallel channel 8, and the main channels 1 are set to two, and the two main channels 1 are symmetrically arranged on both sides of the axial direction of the parallel channel 8.

[0045] The diameter of the parallel channel 8 may be larger than the diameter of the main channel 1 .

[0046] There are two main channels 1, which increases the number of welding stations 7 that can be covered by the dust removal line of the embodiment of the present application, and because the two main channels 1 are symmetrically arranged, it is convenient to reasonably arrange the positions of the branch channels 4.

[0047] In an embodiment where a plurality of demisters 9 are arranged in parallel, the parallel channel 8 may be provided with a plurality of outlets, each outlet being connected to an inlet of the demister 9 respectively, so that the plurality of demisters 9 may be arranged in parallel, and the outlets of the plurality of demisters 9 are connected to the inlet of the electrostatic precipitator 10.

[0048] In some embodiments, the branch channel 4 is provided with a valve.

[0049] The valve can be selected from the prior art, and its structure and working principle are well known to those skilled in the art and will not be described in detail here.

[0050] The branch channel 4 can be opened and closed by the valve, so that when the welding station 7 stops working, the corresponding branch channel 4 can be closed.

[0051] The above embodiments are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made by ordinary technicians in this field to the technical solutions of the present invention should all fall within the protection scope determined by the claims of the present invention.
