[0039] In order to understand the embodiments of the present application more clearly, the following Figures 1 to 6 The embodiments of the present application are described in detail.

[0040] like Figures 1 to 4 As shown, the present application provides a dust removal device 1, comprising a main body 11, a negative pressure device 12, and a first blocking portion 13. The main body 11 has a hollow structure and includes a first opening 111 and a second opening 112 arranged along a first direction X; the negative pressure device 12 is disposed on a side wall of the main body 11 between the first opening 111 and the second opening 112; the first blocking portion 13 is disposed on an inner side wall of the main body 11 between the negative pressure device 12 and the first opening 111, and extends into the interior of the main body 11.

[0041] The main body 11 refers to a component with a hollow structure, and its specific shape can be a regular shape such as a cylinder, a square, or an irregular shape, which is not limited in the embodiment of the present application.

[0042] Negative pressure device 12 is a device capable of extracting negative pressure. Negative pressure device 12 creates a negative pressure within main body 11 of dust removal device 1, thereby extracting gas from main body 11. In some embodiments, negative pressure device 12 may also be a vacuum device, creating a vacuum within main body 11 and improving the ability to extract gas and particles such as welding slag from main body 11. Specifically, negative pressure device 12 and main body 11 may be connected via a pipe for easy replacement and maintenance, or they may be connected via an integrally formed channel provided on the side wall of main body 11, thereby increasing the integration of dust removal device 1.

[0043] The first direction is the direction in which the welding channel between the laser and the workpiece to be welded points during welding.

[0044] The main body 11 includes a first opening 111 and a second opening 112 arranged along a first direction X. This prevents the main body 11 from blocking the laser and affecting welding quality. Furthermore, during welding, the first opening 111 communicates with the outside, while the second opening 112 corresponds to the workpiece 2 to be welded. By applying negative pressure to the main body 11, impurities such as welding slag and smoke formed on the surface of the workpiece 2 can be drawn out through the second opening 112 by the negative pressure device 12, ensuring welding quality.

[0045] The first blocking portion 13 is disposed on the inner sidewall of the main body 11 between the negative pressure device 12 and the first opening 111. The connection between the first blocking portion 13 and the inner wall of the main body 11 can be a detachable connection such as plugging, or a non-detachable connection such as welding or gluing. In some embodiments, multiple first blocking portions 13 may be disposed at intervals around the inner wall of the main body 11. Preferably, in some embodiments, the first blocking portion 13 completely surrounds the inner wall of the main body 11.

[0046] The first blocking portion 13 extends toward the interior of the main body 11 , and its extension direction can be perpendicular to the inner side wall of the main body 11 , or it can be inclined at a certain angle to the inner side wall of the main body 11 . When the first blocking portion 13 extends toward the interior of the main body 11 , it does not form a completely closed entity, that is, a through hole is reserved on the first blocking portion 13 for the laser to pass through.

[0047] By arranging a first blocking portion 13 on the inner side wall of the main body 11 between the negative pressure device 12 and the first opening 111, the gas from the first outlet can be blocked during welding, ensuring that most of the gas extracted by the negative pressure device 1 comes from the second outlet 112, thereby improving the ability to extract gas impurities generated during welding of the workpiece 2 to be welded at the second outlet 112, further improving the dust removal effect and improving the welding quality.

[0048] like Figure 4As shown, in some embodiments, the first blocking portion 13 extends obliquely toward the inside of the body portion 11 , and the opening of the first blocking portion 13 gradually decreases along the first direction X.

[0049] The first blocking portion 13 extends obliquely toward the inside of the body 11 , that is, when extending toward the inside of the body 11 , the first blocking portion 13 forms a certain angle a with the inner wall of the body 11 , and the angle a ranges from greater than 0° to less than 90°.

[0050] By extending the first blocking portion 13 obliquely toward the inside of the main body 11 and gradually reducing the opening of the first blocking portion 13 along the first direction X, on the one hand, the first blocking portion 13 can block the gas from the first opening 111, and on the other hand, the first blocking portion 13 can also guide the smoke, welding slag and other impurities from the second opening 112, so that they are sucked into the negative pressure device along the channel between the first blocking portion 13 and the inner wall of the main body 11, thereby further improving the dust removal effect of the dust removal device.

[0051] like Figure 1 and Figure 4 As shown, in some embodiments, the dust removal device 1 further includes a second blocking portion 14 , which is disposed on the inner side wall of the main body 11 and extends toward the interior of the main body 11 to form a first opening 111 .

[0052] Similarly, the connection between the second blocking portion 14 and the inner wall of the main body 11 can be a detachable connection such as plugging, or a non-detachable connection such as welding or gluing. When the second blocking portion 14 extends into the interior of the main body 11, its extension direction can be perpendicular to the inner side wall of the main body 11, or it can extend at an angle to the inner side wall of the main body 11.

[0053] Specifically, the second blocking portion 14 can be provided at the end of the main body 11 along the first direction X, or can be provided at a certain distance from the end of the main body 11 , and this embodiment of the present application does not impose any limitation on this.

[0054] The second blocking portion 14 can further block the gas from the first opening 111 from entering the dust removal device 1 , ensuring that the gas and other impurities extracted by the negative pressure device 12 mostly come from the second opening 112 , further improving the dust removal effect of the dust removal device 1 .

[0055] like Figure 1 and Figure 4 As shown, in some embodiments, the second blocking portion 14 is disposed at an end portion of the body portion 11 along the first direction X.

[0056] By disposing the second blocking portion 14 at the end of the body portion 11 along the first direction X, the volume of the dust removing device 1 can be reduced.

[0057] like Figures 2 to 4 As shown, in some embodiments, the dust removal device 1 includes an abutment portion 15 , which is arranged obliquely along the first direction X at the end of the body portion 11 away from the first opening and extends toward the inside of the body portion 11 to form a second opening 112 .

[0058] The abutting portion 1 and the main body 11 can be integrally formed to improve the integration of the dust removal device 1. The abutting portion 1 and the main body 11 can also be manufactured separately and then connected and assembled into one body to reduce the manufacturing difficulty of the dust removal device 1. When the abutting portion 1 and the main body 11 are manufactured separately and then connected and assembled into one body, the connection between the two can be a detachable connection such as plug-in connection, or a non-detachable connection such as welding or gluing.

[0059] The abutment portion 15 is arranged obliquely along the first direction X at the end of the main body 11 away from the first opening. The inclined arrangement means that the abutment portion 15 is arranged to protrude from the main body 11 along the first direction X, so as to ensure that the second opening 112 can be as close to the workpiece to be welded 2 as possible, or even rest on the workpiece to be welded 2, so as to enhance the dust removal effect of the dust removal device 1 on the workpiece to be welded.

[0060] like Figure 2 As shown, in some embodiments, the abutting portion 15 is an arc-shaped structure.

[0061] The abutting portion 15 may be a regular arc structure such as a circular arc, or an irregular arc structure composed of multiple arcs, which is not limited in the embodiment of the present application.

[0062] By setting the abutment 15 as an arc-shaped structure, on the one hand, the smoke, welding slag and other impurities generated during welding can be sucked into the negative pressure device 12 along the arc at the maximum wind speed, preventing the obstruction of dead corners such as corners from weakening the flow rate and causing the accumulation or falling of impurities such as welding slag and smoke, which pollutes the surface of the workpiece 2 to be welded and affects the welding quality; on the other hand, the arc-shaped abutment 15 makes it easier for the abutment 15 to be attached to the workpiece 2 to be welded, and the second opening 112 can be set to fit the workpiece 2 to be welded, preventing external gas from flowing into the dust removal device 1 from the gap between the second opening 112 and the workpiece 2 to be welded, thereby increasing the negative pressure in the dust removal device 1, so that the welding slag, smoke and other impurities generated on the surface of the workpiece to be welded are sucked into the negative pressure device 12 at the maximum flow rate, thereby increasing the dust removal effect.

[0063] like Figures 2 to 4 As shown, in some embodiments, a circular arc transition is provided between the abutting portion 15 and the inner side wall of the main body portion 11 .

[0064] The arc transition setting can further prevent the corner at the connection between the abutment portion 15 and the main body portion 11 from being blocked and reducing the flow rate, causing impurities such as welding slag and smoke to accumulate or fall, contaminating the surface of the welded part 2 and affecting the welding quality.

[0065] like Figure 5 and Figure 6 In another aspect, the present application provides a welding device for welding a workpiece 2 to be welded, comprising a dust removal device 1 and a welding device 3. The dust removal device 1 is disposed on one side of the workpiece 2 to be welded along a first direction X, and a first opening 111 is disposed corresponding to the workpiece 2 to be welded; the welding device 2 is disposed on a side of the dust removal device 1 away from the workpiece 2 to be welded along the first direction X.

[0066] The welding device 2 has a laser emitting portion. The laser emitted by the welding impurities 2 passes through the first opening 111 and the second opening 112 along the first direction X and penetrates the main body 11 to reach the workpiece 2 to be welded, thereby welding the workpiece 2.

[0067] By setting a dust removal device 1 in the welding equipment, the gas from the first outlet 111 can be blocked during welding, ensuring that most of the gas extracted by the negative pressure device 12 comes from the second outlet 112, thereby improving the ability to extract gas impurities from the workpiece 2 to be welded located at the second outlet 112, further improving the dust removal effect and improving the welding quality.

[0068] like Figure 5 and Figure 6 As shown, in some embodiments, the welding equipment further includes a driving device 4, which is arranged to drive the dust removal device 1 and / or the workpiece 2 to be welded.

[0069] The driving device 4 can be a driving device such as a cylinder, an electric cylinder, a hydraulic rod, or a driving source such as a motor, and the embodiment of the present application does not limit this.

[0070] Specifically, the driving device 4 can be separately connected to the dust removal device 1 or the workpiece 2 to be welded, and the distance between the second opening 112 and the workpiece 2 to be welded can be adjusted by driving the dust removal device 1 or the workpiece 2 to be welded, thereby simplifying the adjustment process. In other embodiments, the driving device 4 can also be simultaneously connected to the dust removal device 1 and the workpiece 2 to be welded, and the distance between the second opening 112 and the workpiece 2 to be welded can be adjusted by driving the dust removal device 1 and the workpiece 2 to be welded, thereby accelerating the adjustment process.

[0071] By setting up the driving device 4, the distance between the second opening 112 and the workpiece 2 to be welded can be adjusted. On the one hand, it is convenient for loading and prevents the workpiece 2 to be welded from interfering with the dust removal device 1 during loading and damaging the dust removal device 1 or the workpiece 2 to be welded; on the other hand, the distance between the second opening 112 and the workpiece 2 to be welded can be reduced, so that the workpiece 2 to be welded is as close to the second opening 112 as possible to ensure the dust removal effect.

[0072] like Figure 6As shown, in some embodiments, the driving device 4 also includes a guide rail 41 and a slider 42, and the dust removal device 1 is connected to the slide rail 41 or the slider 42, or the workpiece 2 to be welded is connected to the slide rail 41 or the slider 42, so as to facilitate the adjustment of the distance between the second opening 112 and the workpiece 2 to be welded.

[0073] In some embodiments, the second opening 112 is arranged in close contact with the workpiece 2 to be welded. By arranging the second opening 112 in close contact with the workpiece 2, external air can be prevented from flowing into the dust removal device 1 through the gap between the second opening 112 and the workpiece 2 to be welded. This can increase the negative pressure within the dust removal device 1, allowing impurities such as welding slag and smoke generated on the surface of the workpiece to be welded to be drawn into the negative pressure device 12 at the maximum flow rate, thereby enhancing the dust removal effect.

[0074] Specifically, such as Figures 1 to 6 As shown, during loading, the driving device 4 drives the dust removal device 1 and / or the workpiece to be welded 2 away from each other, so that the workpiece to be welded can be conveniently placed in the welding position.

[0075] During operation, the driving device 4 drives the dust removal device 1 and / or the workpiece to be welded 2 to approach each other so that the second opening 112 is fitted on the surface of the workpiece to be welded 2, and then starts the negative pressure device 12 and the welding device 3. When the welding device 3 welds the workpiece to be welded 2, the negative pressure device 12 sucks the smoke, particles, gas and other impurities generated on the surface of the workpiece to be welded 2 into the negative pressure device 12 to prevent these impurities from blocking the laser of the welding impurities 2 or falling on the surface of the workpiece to be welded 2, thereby affecting the welding quality.

[0076] After welding is completed, the welding device 2 and the dust removal device 1 stop working, and the driving device 4 drives the dust removal device 1 and / or the workpiece 2 to be welded away from each other, so as to facilitate the unloading of the workpiece 2 to be welded after welding.

[0077] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
