[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] In the description of this utility model, it should be understood that the terms "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0035] The following is for reference. Figures 1-5 Describes a welding slag collection device 100 according to a first aspect embodiment of the present invention.

[0036] like Figure 1 As shown, the welding slag collection device 100 according to the first aspect of the present invention includes: a dust removal hood 10, a jacket 30, and a particle collection element 50. A dust removal chamber 101 is formed inside the dust removal hood 10, and the dust removal hood 10 is provided with a dust inlet 11 and a dust outlet 12 communicating with the dust removal chamber 101. The dust outlet 12 is used to connect to a negative pressure adsorption mechanism.

[0037] Through the above technical solution, welding slag enters the dust removal chamber 101 through the dust inlet 11. Under the action of the negative pressure adsorption mechanism, some of the larger welding slags are discharged from the dust removal chamber 101 in a timely manner through the dust outlet 12 with the airflow, thereby achieving effective collection and separation of welding slag and achieving dust removal effect.

[0038] Here, by utilizing the enclosure effect of the dust hood 10, the welding slag generated during the welding process is effectively collected into the dust removal chamber 101 inside the dust hood 10, thereby reducing the pollution of the surrounding environment by the welding slag, preventing the welding slag from falling onto the surface of the workpiece to be welded and causing product quality defects, and helping to improve product yield and production stability.

[0039] It is worth noting that the welding slag also includes some smaller, lighter pieces. These fine pieces of slag are not easily carried away by the airflow under negative pressure and tend to adhere directly to the inner wall of the dust collection chamber 101. As the welding process continues, once these fine pieces of slag reach saturation on the inner wall, they may fall off due to vibration or airflow disturbance. This could cause the slag to fall back into the welding area through the dust inlet 11, subsequently adhering to the surface of the workpiece, affecting welding quality, and even causing defects in the product's appearance or performance.

[0040] Optionally, the dust cover 10 may be square, trapezoidal, or other regular or irregular shapes, depending on the usage environment. This application does not impose any specific restrictions.

[0041] To address the aforementioned issues, the slag collection device 100 of this embodiment further includes a jacket 30. The jacket 30 is detachably mounted on the inner wall of the dust collector 10. During welding, some fine slag adheres to the surface of the jacket 30. Once the slag has accumulated to a certain extent, the user can easily remove the jacket 30 from the inner wall of the dust collector 10 for centralized cleaning or replacement. Therefore, by providing the jacket 30, the slag collection device 100's ability to capture and manage fine particles is enhanced, the risk of secondary contamination from welding slag is avoided, and the dust removal efficiency of the slag collection device 100 is improved.

[0042] In some optional embodiments, the shape and size of the interlayer 30 are adapted to the inner wall of the dust collector 10, so that the interlayer 30 can be firmly attached to the inner wall of the dust collector 10 and is not easily displaced or detached due to airflow impact or vibration, thereby improving the installation reliability of the interlayer 30 in the dust collector 101 and ensuring the reliability of welding slag collection.

[0043] To further improve the slag collection capacity of the slag collection device 100, the slag collection device 100 of this application embodiment also includes a particle trapping element 50 located in the dust removal chamber 101, and the particle trapping element 50 is connected to the interlayer 30. By setting the particle trapping element 50 on the interlayer 30, the ability to capture fine slag is enhanced, the overall dust removal efficiency is improved, and the detachable structure of the interlayer 30 facilitates the periodic cleaning of the particle trapping element 50.

[0044] In some alternative embodiments, the particle trap 50 may take the form of a brush, a spiral, or the like. These forms of particle traps 50 can guide, intercept, or adsorb welding slag floating with the airflow, further improving the dust removal efficiency of the welding slag collection device 100.

[0045] According to some alternative embodiments, in combination Figure 1 and Figure 2 The dust removal hood 10 includes a first half-hood 141 and a second half-hood 142 that are detachably connected. When the first half-hood 141 and the second half-hood 142 are connected, they enclose the dust removal chamber 101. The interlayer 30 is disposed on at least one of the first half-hood 141 and the second half-hood 142.

[0046] The dust cover 10 is divided into two detachable half covers, which makes it easier to install the interlayer 30 onto a single half cover first during the assembly process, and then splice the whole structure together, simplifying the assembly process and making it easier to disassemble the interlayer 30.

[0047] Optionally, the interlayer 30 can be a one-piece design or a separate design. When the interlayer 30 is a one-piece design, there are no seams in its structure, which reduces the risk of welding slag falling through gaps and ensures dust removal efficiency. When the interlayer 30 is a separate design, the disassembled interlayer 30 can be easily opened to thoroughly clean the welding slag or particle trap 50 inside, ensuring the dust removal effect of the device during long-term operation. Furthermore, areas with a large amount of residual welding slag in the interlayer 30 can be disassembled and cleaned separately without the need for complete disassembly, reducing maintenance time costs.

[0048] Here, the interlayer 30 adopts a modular design for easy and quick assembly and disassembly. When the interlayer 30 is full of welding slag, it can be completely disassembled and immediately replaced with another clean interlayer 30, thus resuming welding operations in a short time without waiting for cleaning to be completed, shortening downtime. The replaced interlayer 30 can be cleaned in a concentrated manner during non-operational periods, further improving production continuity and welding efficiency.

[0049] Optionally, the dust cover 10 includes a quick-release component disposed between the first half-cover 141 and the second half-cover 142 to enable quick connection and separation of the two. The quick-release component includes, but is not limited to, snap-fit ​​components, fasteners, magnetic components, etc.

[0050] For further details, please refer to [link / reference]. Figure 2 The interlayer 30 includes a first inner layer 31 and a second inner layer 32. The first inner layer 31 is detachably disposed on the inner wall of the first half cover 141, and the second inner layer 32 is detachably disposed on the inner wall of the second half cover 142.

[0051] Therefore, the first and second interlayers 30 can be separated synchronously with the disassembly of the first half-cover 141 and the second half-cover 142. This arrangement allows operators to simultaneously open the dust hood 10 and the interlayers 30 to check the internal welding slag accumulation and assess whether the interlayers 30 need to be replaced.

[0052] Furthermore, an inner inlet 33 is formed between the first inner layer 31 and the second inner layer 32, and the inner inlet 33 is positioned directly opposite the dust inlet 11. The inner inlet 33 cooperates with the dust inlet 11 to guide welding slag smoothly into the interior of the dust removal chamber 101.

[0053] An inner outlet 34 is formed between the first inner layer 31 and the second inner layer 32, and the inner outlet 34 is positioned directly opposite the dust outlet 12. The inner outlet 34 cooperates with the dust outlet 12 to allow the airflow containing welding slag to be smoothly discharged under the action of the negative pressure adsorption mechanism.

[0054] Both the first inner layer 31 and the second inner layer 32 are provided with particle trapping elements 50. By setting the particle trapping elements 50, the welding slag can be intercepted and adsorbed multiple times in the dust removal chamber 101, thereby improving the welding slag collection device 100's ability to capture welding slag and ensuring the dust removal effect.

[0055] Optionally, the first half-cover 141 and the first inner layer 31 are connected by a snap-fit ​​or magnetic connection. The second half-cover 142 and the second inner layer 32 are connected by a snap-fit ​​or magnetic connection.

[0056] This allows for quick assembly and disassembly of the first half-cover 141 and the first inner layer 31, and the second half-cover 142 and the second inner layer 32, without the need for tools, making the operation simple and fast.

[0057] In some technical solutions, the connection method is a snap-fit ​​connection, which facilitates quick positioning and locking between the first half-cover 141 and the first inner layer 31, and / or the second half-cover 142 and the second inner layer 32, thereby improving the reliability of the welding slag collection device 100.

[0058] In some other technical solutions, the connection method is magnetic connection, which facilitates quick connection and separation of the first half-cover 141 and the first inner layer 31, and / or the second half-cover 142 and the second inner layer 32.

[0059] In some alternative embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the dust removal hood 10 is also provided with a laser inlet 13 that communicates with the dust removal chamber 101. The laser inlet 13 is arranged opposite to the dust inlet 11, and a laser channel 102 is formed inside the dust removal hood 10 between the laser inlet 13 and the dust inlet 11.

[0060] Specifically, the laser beam enters the dust hood 10 from the laser inlet 13, passes through the dust removal chamber 101, and exits from the dust inlet 11 to be used on the surface of the workpiece to be welded for welding operations. During this process, the laser channel 102 formed inside the dust removal chamber 101 ensures that the laser beam passes smoothly without being blocked by the interlayer 30 or the particle trap 50, thereby ensuring the continuity of welding.

[0061] Meanwhile, the welding slag generated during the welding process can enter the dust removal chamber 101 through the dust inlet 11, and be guided to the dust outlet 12 by the airflow under negative pressure.

[0062] The interlayer 30 and the particle trap 50 are positioned away from the laser channel 102 area, so as not to affect the laser transmission, but to achieve the adsorption and interception of welding slag, enabling welding and dust removal to work together.

[0063] According to some optional embodiments, a portion of the interlayer 30 covers the inner wall surface of the dust outlet 12. Since the dust outlet 12 is located at an airflow turning point, welding slag is easily deposited in this area, and long-term accumulation may cause blockage of the dust outlet 12, affecting dust removal efficiency. Extending a portion of the interlayer 30 to the inner wall surface of the dust outlet 12 allows the welding slag deposited in this area to adhere to the surface of the interlayer 30. Thus, when cleaning the interlayer 30, the welding slag in the dust outlet 12 area can be cleaned simultaneously, preventing blockage of the dust outlet 12, ensuring smooth airflow, and improving dust removal efficiency.

[0064] Specifically, the extension direction of the particle trap 50 forms an angle with the extension direction of the dust inlet 11. By setting this angle, the airflow entering the dust inlet 11 is disturbed when it comes into contact with the particle trap 50, changing the movement trajectory of the welding slag particles and making it easier for some fine welding slag to come into contact with the surface of the particle trap 50 and be adsorbed or intercepted.

[0065] This configuration enhances the ability to capture welding slag, especially fine particles, that enter the dust removal chamber 101 with the airflow, thereby improving dust removal efficiency.

[0066] Specifically, such as Figure 3 and Figure 5 As shown, the particle collecting device 50 includes: a fixing post 51, with an interlayer 30 connected to the end of the fixing post 51. It also includes a spiral blade 521 or bristles 522 disposed on the fixing post 51.

[0067] The spiral blades 521 or bristles 522 can create disturbances in the airflow, changing the trajectory of the welding slag particles and making them more likely to collide with and adhere to the surface of the particle collector 50 or the interlayer 30, thereby improving the collection efficiency of fine welding slag.

[0068] In addition, the spiral blades 521 have a certain guiding effect, which can make the airflow in the dust removal chamber 101 more evenly distributed, reduce eddies and dead corners, avoid local welding slag accumulation, and thus improve dust removal performance.

[0069] Since the particle collector 50 is connected to the interlayer 30 via the fixing post 51, and the interlayer 30 itself is a detachable structure, the entire particle collector 50 can be removed along with the interlayer 30 during cleaning, enabling rapid maintenance and preventing long-term accumulation of welding slag that could cause blockage or contamination.

[0070] According to some optional welding slag collection devices 100 of this utility model, there are multiple particle collecting elements 50, and the multiple particle collecting elements 50 are arranged in multiple rows and columns.

[0071] This multi-row, multi-column arrangement allows the particle collector 50 to form a dense interception area inside the dust removal chamber 101, which can cover more of the airflow path, thereby improving the capture efficiency of fine welding slag particles moving with the airflow and enhancing the dust removal capability.

[0072] Optionally, the number of rows and columns of the particle collecting element 50 can be set according to specific needs. By guiding the airflow, local eddies or blockages are reduced, improving the stability of the dust removal system.

[0073] In some optional embodiments, all particle traps 50 are provided with helical blades 521. By providing helical blades 521, the airflow carrying welding slag can be disturbed as it passes through, thereby increasing the collision probability and adhesion efficiency between welding slag particles in the airflow and the particle traps 50. In addition, the provision of helical blades 521 also increases the contact surface area of ​​the particle traps 50, allowing more welding slag particles to be intercepted and adsorbed, thereby improving the welding slag capture efficiency.

[0074] In some optional embodiments, all particle traps 50 are provided with a bristle 522 structure. The bristle 522 structure can enhance the interception effect of welding slag particles as airflow passes through, thereby improving adsorption efficiency.

[0075] To further improve the collection efficiency of the welding slag collection device 100, in some alternative embodiments, particle traps 50 with spiral blades 521 and particle traps 50 with bristle structures 522 are alternately arranged. For example, one row may be arranged with particle traps 50 with spiral blades 521, and adjacent rows may be arranged with particle traps 50 with bristle structures 522; or one column may be arranged with particle traps 50 with spiral blades 521, and adjacent columns may be arranged with particle traps 50 with bristle structures 522. Through this alternating arrangement, the spiral blades 521 can enhance airflow disturbance and improve particle collision and trapping efficiency, while the bristle structures 522 can improve the interception and cleaning ability of fine particles, thereby achieving a synergistic effect and further improving the collection effect.

[0076] Combination Figure 1 and Figure 3 The welding equipment according to the second aspect of the present invention includes: a slag collection device 100 and a nozzle 200. The nozzle 200 is connected to a dust collector 10, and a welding channel 201 is provided on the nozzle 200. A dust inlet 11 is connected to the welding channel 201. The slag collection device 100 is the welding equipment of the first aspect of the present invention.

[0077] In the above embodiments, the welding equipment integrates the slag collection device 100 with the nozzle component 200 to achieve the collection and processing of slag during the welding operation.

[0078] Specifically, the welding channel 201 on the nozzle 200 is used to guide the welding torch for welding, while the dust inlet 11 is directly connected to the welding channel 201, which can promptly draw the welding slag generated during the welding process into the dust removal chamber 101, thereby achieving simultaneous welding and dust removal, improving the cleanliness of the operation, and thus improving the welding quality.

[0079] The welding equipment of this application embodiment utilizes an improved slag collection device 100, which facilitates timely collection and cleaning of slag, prevents slag from falling onto the workpiece surface, and improves welding quality.
