[0009] The dust extraction device provided in the embodiment of the present application sets the copper nozzle piece on the first end face of the cover plate, and sets the dust extraction assembly on the second end face of the cover plate. The copper nozzle piece presses the object to be welded and exposes the welding area of ​​the object to be welded.

[0051] In order to make the purpose, technical solutions and advantages of this application more clear, this application is further described in detail below with reference to the accompanying drawings and embodiments.

[0052] As the market demand for batteries continues to expand, the production and use of battery products is also increasing. During the battery production and assembly process, the battery terminals are often welded to the conductive connectors. Welding is a process that uses heat, high temperature, or high pressure to join metal parts. During the welding process, smoke, slag, and other impurities are generated. If these impurities are not removed promptly, they will accumulate around the weld points, affecting the welding process and potentially causing problems such as cold welds and weld collapse, which affect the welding effect.

[0053] Based on the above considerations, in order to solve the technical problem that if the smoke, welding slag and other impurities generated during welding are not discharged in time, which may affect the welding effect, a dust extraction device is designed. By setting a cover plate, the dust extraction component is set on the second end face of the cover plate and the first opening is facing the through hole, and the copper nozzle piece is set on the first end face of the cover plate and connected to the through hole of the cover plate. The cover plate can be set on the peripheral side of the welding station, and the copper nozzle piece is made to abut the welding area of ​​the object to be welded. When the welding operation is performed, the smoke, welding slag, etc. generated by welding will gather in the channel of the copper nozzle piece, or pass through the channel of the copper nozzle piece and splash to the second end face. The suction device can form a negative pressure on the cavity of the dust extraction component through the second opening, so that the first opening connected to the cavity can perform a dust extraction operation in the direction of the through hole, and the smoke, welding slag, etc. generated by welding can be extracted in time, thereby reducing the influence of impurities such as smoke, welding slag on the welding operation, and thus achieving the purpose of improving the welding effect.

[0054] The dust extraction device disclosed in the embodiment of the present application can be used to extract dust from the welding operations of the poles and the conductive connecting pieces during the battery production process, and can also be used to extract dust from the welding processes of other components.

[0055] For the convenience of description, the following embodiments are described by taking the dust extraction device used in the welding process of a battery production line as an example.

[0056] Below, the dust extraction device provided in the embodiment of the present application will be introduced and explained.

[0057] Please refer to Figures 1 to 5. An embodiment of the present application provides a dust extraction device 1000, including a copper nozzle 100, a cover plate 200, a dust extraction assembly 300 and an air suction device 500. The copper nozzle 100 is configured to be positioned against the welding area of ​​the object to be welded 2000. The copper nozzle 100 has a through channel 101, the cover plate 200 is provided with a through hole 201, and the cover plate 200 has a first end face 210 and a second end face 220 arranged opposite to each other. The copper nozzle 100 is arranged on the first end face 210, the channel 101 is connected to the through hole 201, the dust extraction assembly 300 is arranged on the second end face 220, and a cavity 301 with a first opening 302 and a second opening 303 is formed inside the dust extraction assembly 300. The first opening 302 faces the through hole 201, and the air suction device 500 is connected to the second opening 303.

[0058] Among them, the cover plate 200 is a tooling part used to play an assembly and connection role. The cover plate 200 is used to undertake the assembly of multiple components such as the copper nozzle 100 and the dust extraction component 300. In addition, the cover plate 200 can be connected to the welding process of the battery production line to perform dust extraction operations on the welding process of the battery production line.

[0059] Specifically, the cover plate 200 is a plate-shaped structure, and therefore, the first end surface 210 and the second end surface 220 of the cover plate 200 refer to two opposite end surfaces in the thickness direction of the cover plate 200 .

[0060] The cover plate 200 is provided with a through hole 201 for communicating with the channel 101 of the copper mouthpiece 100 ; wherein, the number of the through holes 201 can be one or more, and the arrangement of the through holes 201 can be in a straight line or in an arc.

[0061] The copper nozzle piece 100 is used to be placed against the welding area of ​​the object 2000 to be welded, so that the channel 101 of the copper nozzle piece 100 can expose the welding area of ​​the object 2000 to be welded, so that the welding equipment used to perform the welding operation can pass through the through hole 201 and the channel 101 of the copper nozzle piece 100 and perform welding operations on the welding area of ​​the object 2000 to be welded. It can be understood that the welding area of ​​the object 2000 to be welded refers to the area of ​​the object 2000 to be welded where the welding operation is specifically performed; the copper nozzle piece 100 can be placed against the welding area of ​​the object 2000 to be welded, so that the welding area is exposed through the channel 101 of the copper nozzle piece 100, so that external welding equipment can perform welding operations on the welding area.

[0062] When the dust extraction device 1000 is used on a battery production line and performs dust extraction on the welding of the conductive connecting piece, the copper nozzle 100 is used to abut against the welding area of ​​the conductive connecting piece to ensure that the conductive connecting piece and the electrode of the battery cell are tightly fitted.

[0063] The copper nozzle 100 is disposed on the first end surface 210 of the cover plate 200. Specifically, the copper nozzle 100 can be assembled on the cover plate 200 by fasteners, or can be fixed on the cover plate 200 by clamping, welding, or the like.

[0064] The channel 101 of the copper nozzle piece 100 is connected to the through hole 201 of the cover plate 200, so that the welding equipment can pass through the through hole 201 and the channel 101 of the copper nozzle piece 100 on the side of the second end face 220 of the cover plate 200 and perform welding operations on the welding area of ​​the welding object 2000. The impurities generated during welding can pass through the through hole 201 from the channel 101 of the copper nozzle piece 100 and splash toward the second end face 220 of the cover plate 200, and the dust extraction component 300 located on the second end face 220 can remove impurities through the first opening 302 toward the through hole 201, so that the impurities can be extracted in time.

[0065] Specifically, the dust extraction component 300 may include but is not limited to a dust extraction tube, a dust extraction box, a dust extraction adapter, etc.; a cavity 301 is formed inside the dust extraction component 300. It can be understood that the interior of the dust extraction component 300 can specifically form a cavity 301, or can form multiple independent cavities 301, and each cavity 301 has a first opening 302 and a second opening 303. The second opening 303 is used to connect the suction device 500 to form a negative pressure in the cavity 301, and the first opening 302 is used to perform dust extraction operations toward the through hole 201.

[0066] The above-mentioned suction device 500 can be an exhaust fan, a negative pressure device, an induced draft fan, etc. The suction device 500 is used to perform an exhaust operation on the cavity 301 of the dust extraction component 300 through the second opening 303, so that a negative pressure is formed in the cavity 301 of the dust extraction component 300, so that the first opening 302 of the dust extraction component 300 can achieve the purpose of exhausting impurities from the through hole 201.

[0067] The dust extraction device 1000 provided in the embodiment of the present application is provided with the copper nozzle 100 on the first end surface 210 of the cover plate 200, and the dust extraction assembly 300 is provided on the second end surface 220 of the cover plate 200. The copper nozzle 100 presses the object to be welded 2000 and exposes the welding area of ​​the object to be welded 2000. When the welding operation is performed on the welding area, the smoke, welding slag, etc. generated will splash in the channel 101 of the copper nozzle 100 or pass through the channel 101 and splash to the second end surface 220 of the cover plate 200. The air suction device 500 can exhaust the air of the dust extraction assembly 300 through the second opening 303. The cavity 301 forms a negative pressure. The cavity 301 with negative pressure formed in the dust extraction component 300 can adsorb the smoke, welding slag and other impurities in the through hole 201 and the channel 101 of the copper nozzle 100 or on the second end face 220 through the first opening 302, and can discharge the smoke, welding slag and other impurities in time, thereby reducing the amount of smoke, welding slag and other impurities retained on the copper nozzle 100 and the second end face 220, thereby reducing the influence of smoke, welding slag and other impurities on the welding effect, thereby improving the welding effect.

[0068] Please refer to Figures 1 to 3, 5 and 6. In some embodiments, the dust extraction assembly 300 includes a dust extraction tube body 310 and a cover member 320. The dust extraction tube body 310 is arranged on the second end face 220. A cavity 301 is formed inside the dust extraction tube body 310. An opening 311 and a second opening 303 are opened on the dust extraction tube body 310. The cover member 320 is arranged on the dust extraction tube body 310. The cover member 320 is configured to block part of the opening 311 to form a first opening 302.

[0069] It is understood that the dust extraction tube 310 can be, but is not limited to, a square tube structure, a circular tube structure, etc.; the dust extraction tube 310 can be a straight tube or a curved tube, or include both straight tube sections and curved sections. The dust extraction tube 310 can be a metal tube body, an alloy tube body, etc., such as an aluminum alloy tube body.

[0070] The dust extraction tube body 310 is disposed on the second end surface 220. Specifically, the dust extraction tube body 310 can be assembled on the second end surface 220 by fasteners, or the dust extraction tube body 310 can be fixedly mounted on the second end surface 220 by means of clamping, welding, etc. When the dust extraction tube body 310 is assembled on the second end surface 220 by fasteners, the dust extraction tube body 310 can be removed by loosening the fasteners, thereby more conveniently performing maintenance operations on the dust extraction tube body 310 or replacing the dust extraction tube body 310.

[0071] A cavity 301 is formed inside the dust extraction tube body 310. Specifically, the cavity 301 can be directly formed inside the dust extraction tube body 310, and an opening 311 and a first opening 302 are provided on the dust extraction tube body 310, and the opening 311 and the first opening 302 are respectively connected to the cavity 301; or, an empty groove is provided on the dust extraction tube body 310, and when the dust extraction tube body 310 is assembled on the second end face 220, the second end face 220 can cover part of the empty groove, so that the second end face 220 is enclosed in the empty groove to form the cavity 301, and the part of the empty groove not covered by the second end face 220 forms the opening 311.

[0072] Wherein, the cover member 320 is used to block part of the opening 311 so that the other part of the opening 311 that is not blocked forms the first opening 302. Specifically, the cover member 320 can be, but is not limited to, a cover sheet, a cover plate 200, a block, etc. The cover member 320 can be fixedly mounted on the dust extraction tube body 310, or the cover member 320 can also be movably connected to the dust extraction tube body 310. When the cover member 320 is movably connected to the dust extraction tube body 310, specifically, the cover member 320 can be detachably connected to the dust extraction tube body 310. When the cavity 301 of the dust extraction tube body 310 needs to be cleaned and maintained, the cover member 320 can be removed to expose the opening 311 completely, so that the cleaning and maintenance operations inside the dust extraction tube body 310 can be performed more conveniently.

[0073] In this arrangement, the dust extraction tube body 310 is arranged on the second end face 220, and the cover member 320 is arranged on the dust extraction tube body 310 and covers part of the opening 311, thereby exposing the other part of the opening 311 and forming a first opening 302 for adsorbing impurities such as smoke, welding slag, etc. The air suction device 500 can form a negative pressure on the cavity 301 of the dust extraction tube body 310 through the second opening 303, and then can perform a dust extraction operation on the through hole 201 through the first opening 302. At the same time, the air suction device 500 is connected to the second opening 303 of the dust extraction assembly 300, and the cavity 301 of the dust extraction assembly 300 can directly perform a dust extraction operation on the through hole 201 and the channel 101 of the copper nozzle 100 through the first opening 302, thereby reducing the use of pipes for guiding air, thereby reducing the obstruction of gas flow due to the bending and switching of the pipes, so as to achieve the purpose of optimizing the dust removal wind speed and optimizing the dust extraction effect.

[0074] Please refer to Figures 5 to 7. In some embodiments, either the dust extraction tube body 310 or the cover member 320 has an adjustment structure 321, and the other one of the dust extraction tube body 310 and the cover member 320 has a connecting structure 312, which is configured to be connectable to any point of the adjusting structure 321.

[0075] Specifically, the adjustment structure 321 can be set on the dust extraction tube body 310, and the connection structure 312 can be set on the cover 320; or, the adjustment structure 321 can be set on the cover 320, and the connection structure 312 can be set on the dust extraction tube body 310.

[0076] It can be understood that the adjustment structure 321 can be connected to the connecting structure 312, and the connecting structure 312 can be connected to any point of the adjustment structure 321, that is, the connection position between the connecting structure 312 and the adjustment structure 321 can be located at any point of the adjustment structure 321, so that the cover 320 can adjust the position of the dust extraction tube body 310 by adjusting the connection position between the adjustment structure 321 and the connecting structure 312, and then adjust the area of ​​the opening 311 blocked by the cover 320, so as to achieve the purpose of adjusting the size of the first opening 302, and finally achieve the purpose of adjusting the size of the first opening 302 to improve the dust extraction effect.

[0077] Among them, the above-mentioned adjustment structure 321 can be a waist-shaped hole, and the connecting structure 312 can be a connecting hole 431. When the cover part 320 is assembled on the dust extraction tube body 310, the cover part 320 can be placed on the dust extraction tube body 310, and the connecting hole 431 is relatively connected with the waist-shaped hole. The purpose of assembling the cover part 320 on the dust extraction tube body 310 can be achieved by using fasteners to pass through the waist-shaped hole and the connecting block for fastening connection; in the process of relative communication between the connecting hole 431 and the waist-shaped hole, the connecting hole 431 can be adjusted along the length direction of the waist-shaped hole to adjust the relative position of the cover part 320 and the dust extraction tube body 310, until the position of the cover part 320 relative to the dust extraction tube body 310 is adjusted into place, and then the installation can be completed using fasteners.

[0078] Alternatively, the above-mentioned adjustment structure 321 can also be a plurality of adjustment circular holes, and the plurality of adjustment circular holes can be arranged in any direction, for example, the plurality of adjustment circular holes are arranged along the length direction or width direction of the opening 311, and the connecting structure 312 can be a connecting hole 431; when the cover part 320 is assembled on the dust extraction tube body 310, the cover part 320 can be placed on the dust extraction tube body 310, and the connecting hole 431 can select one or more of the plurality of adjustment circular holes according to needs to be connected to each other, so as to adjust the position of the cover part 320 connected to the dust extraction tube body 310, and finally use fasteners to complete the installation.

[0079] Alternatively, the above-mentioned adjustment structure 321 and the connecting structure 312 can both be waist-shaped holes; alternatively, the above-mentioned adjustment structure 321 and the connecting structure 312 can both be hole groups consisting of multiple circular holes; alternatively, one of the above-mentioned adjustment structure 321 and the connecting structure 312 can be a waist-shaped hole, and the other can be a hole group consisting of multiple circular holes.

[0080] In this way, by connecting the connecting structure 312 to the adjusting structure 321, the purpose of assembling the cover member 320 on the dust extraction tube body 310 is achieved. At the same time, by changing the position where the connecting structure 312 is connected to the adjusting structure 321, the cover member 320 of the cover plate 200 can block the area of ​​the opening 311, thereby adjusting the area of ​​the first opening 302, thereby adjusting the suction volume of the first opening 302 to achieve the purpose of improving the dust extraction effect.

[0081] Referring to FIG. 6 , in some embodiments, the adjustment structure 321 is a waist-shaped hole, and the connection structure 312 is a mounting hole.

[0082] A waist-shaped hole is a hole formed by combining two semicircular holes at each end and a long, rectangular hole in the middle. A mounting hole is a circular hole for fasteners to pass through. Specifically, the number of waist-shaped holes corresponds to the number of mounting holes. The number of waist-shaped holes can be one or more, and the number of mounting holes can also correspond to one or more.

[0083] The mounting hole can be arranged opposite to and connected to the waist-shaped hole, and the connecting position of the mounting hole can be adjusted along the length direction of the waist-shaped hole, so as to adjust the relative position of the cover 320 and the dust extraction tube body 310.

[0084] Specifically, the waist-shaped hole can be opened on the cover 320, and the mounting hole can be opened on the dust extraction tube body 310; or, the waist-shaped hole can be opened on the dust extraction tube body 310, and the mounting hole can be opened on the cover 320.

[0085] With such a configuration, the mounting hole can be aligned with any position of the waist-shaped hole, and the cover member 320 can be assembled on the dust extraction tube body 310 using fasteners to achieve the installation and position adjustment of the cover member 320, thereby achieving the adjustment of the area of ​​the opening 311 blocked by the cover member 320, thereby adjusting the size of the first opening 302 to achieve the purpose of optimizing the dust extraction effect.

[0086] For example, in some specific embodiments, the dust extraction tube body 310 can be a square tube. When the dust extraction tube body 310 is assembled on the second end face 220, a rectangular opening 311 is provided on the tube wall on the side where the dust extraction tube body 310 intersects with the second end face 220 and is close to the through hole 201, and one side edge of the opening 311 is flush with the second end face 220; the sealing cover 320 can be a rectangular cover plate, and the length of the cover plate is greater than the length of the opening 311; a waist-shaped hole is provided on the cover plate, and the length direction of the waist-shaped hole is arranged along the width direction of the cover plate, and the number of the waist-shaped holes is multiple, and the multiple waist-shaped holes are respectively provided at the opposite ends of the waist-shaped holes in the length direction; the dust extraction tube body 310 is provided with a mounting hole, and the number of the mounting holes is multiple, and the mounting holes are respectively provided on the opposite sides of the dust extraction tube body 310 in the length direction of the opening 311, and the mounting holes and the waist-shaped holes are respectively provided correspondingly. During installation, the cover is placed on the dust extraction tube body 310, and the waist-shaped hole of the cover is relatively connected to the corresponding mounting hole of the dust extraction tube body 310. At this time, the cover can cover part of the opening 311, that is, the opening 311 is formed along the width direction from the side edge flush with the second end face 220 to the edge of the cover to form a first opening 302; then the cover can be moved and adjusted along the length direction of the waist-shaped hole to adjust the range of the first opening 302, thereby achieving the purpose of optimizing the dust extraction effect; after the adjustment is completed, use bolts to pass through the waist-shaped hole and the mounting hole and tighten the nut to achieve the connection between the cover and the dust extraction tube body 310.

[0087] Referring to FIG. 2 to FIG. 5 , in some embodiments, the cover plate 200 is provided with a chamfer 230 at the connection position between the through hole 201 and the second end surface 220 .

[0088] It is understandable that chamfering 230 refers to the process of cutting the corners of a workpiece into a certain slope. Specifically, the chamfering 230 can be a round chamfer 230 or a straight chamfer 230.

[0089] With such arrangement, the cavity 301 of the dust extraction component 300 forms a negative pressure due to the suction device 500 connected to the second opening 303, so that the cavity 301 with negative pressure can perform a dust extraction operation on the through hole 201 through the first opening 302, and the negative pressure adsorption of the through hole 201 and the channel 101 of the copper mouthpiece 100 through the first opening 302 forms an airflow flowing to the first opening 302, and a chamfer 230 is provided at the connection position between the second end face 220 and the inner wall of the through hole 201, when the airflow flows out of the through hole 201, the chamfer 230 can play a role of guiding the airflow, so that the airflow can flow more smoothly into the first opening 302 to form a dust extraction effect; the chamfer 230 can improve the flow rate and flow of the airflow flowing from the channel 101 of the copper mouthpiece 100 to the first opening 302, thereby effectively improving the dust extraction effect in the channel 101 of the copper mouthpiece 100.

[0090] Please refer to Figures 2 to 5. In some embodiments, the cover plate 200 is provided with a plurality of through holes 201, and the number of the copper nozzle pieces 100 is multiple, and the multiple copper nozzle pieces 100 are arranged on the first end surface 210 and are respectively connected to the corresponding through holes 201; a plurality of cavities 301 are formed inside the dust extraction component 300, and the first openings 302 of each cavity 301 are respectively facing the corresponding through holes 201.

[0091] It is understood that the cover plate 200 has a plurality of through holes 201, which can be arranged sequentially and spaced apart along any direction; alternatively, the plurality of through holes 201 can be arranged sequentially and spaced apart along any arc; alternatively, the plurality of through holes 201 can be distributed in an array on the cover plate 200. When the plurality of through holes 201 are distributed in an array on the cover plate 200, the dust extraction assembly 300 can include a plurality of dust extraction tubes 310, with a dust extraction tube 310 disposed on one side of each column of through holes 201, and the first openings 302 of the dust extraction tubes 310 facing each corresponding through hole 201 in that column.

[0092] There are multiple copper nozzle pieces 100. Specifically, the number of copper nozzle pieces 100 can be consistent with the number of through holes 201, and the channels 101 of each copper nozzle piece 100 are respectively connected to the corresponding through holes 201; or, the number of copper nozzle pieces 100 can be less than the number of through holes 201.

[0093] Several cavities 301 are formed inside the dust extraction component 300 . Specifically, one cavity 301 may be formed inside the dust extraction component 300 , or multiple cavities 301 may be formed inside the dust extraction component 300 .

[0094] The first opening 302 of each cavity 301 faces the corresponding through hole 201 respectively. Specifically, each cavity 301 has a first opening 302, and the first opening 302 corresponding to each cavity 301 is used to perform dust extraction operations on a through hole 201 and a connected copper mouthpiece 100; or, each cavity 301 can have multiple first openings 302, and each first opening 302 can perform dust extraction operations on a through hole 201 and a connected copper mouthpiece 100.

[0095] With such an arrangement, when there are multiple copper nozzle pieces 100, multiple through holes 201 are also opened on the cover plate 200, so that multiple copper nozzle pieces 100 can be connected to the corresponding through holes 201, and the welding operation can be carried out simultaneously through the multiple through holes 201 and the channels 101 of the connected copper nozzle pieces 100; at the same time, a plurality of cavities 301 are formed inside the dust extraction component 300, and the first openings 302 of each cavity 301 are respectively facing the through holes 201, so that when welding operations are performed in any copper nozzle piece 100, there is a first opening 302 facing the corresponding through hole 201, and the dust extraction operation is performed on the copper nozzle piece 100 connected to the through hole 201 through the first opening 302 using the dust extraction component 300.

[0096] Referring to FIG. 2 to FIG. 5 and FIG. 7 , in some embodiments, the dust extraction assembly 300 has a plurality of first openings 302 , and each cavity 301 is connected to at least one first opening 302 .

[0097] It can be understood that when the dust extraction component 300 includes a dust extraction tube body 310, one or more cavities 301 can be formed in the dust extraction tube body 310, and one or more first openings 302 can be opened on the dust extraction tube body 310; any cavity 301 has at least one first opening 302, specifically, one of the cavities 301 can have a first opening 302, and the cavity 301 is connected to the outside through the opening; or, a cavity 301 can have multiple first openings 302, and the cavity 301 is connected to the outside through multiple first openings 302 respectively, and the multiple first openings 302 can respectively face multiple through holes 201, so that one cavity 301 can perform dust extraction operations on multiple through holes 201 through multiple first openings 302.

[0098] At the same time, each cavity 301 has a second opening 303, and the second opening 303 of each cavity 301 is connected to the suction device 500 to form a negative pressure, so that the dust extraction operation can be carried out on the through hole 201 and the channel 101 of the copper mouthpiece 100 through the first opening 302.

[0099] With such configuration, each cavity 301 of the dust extraction assembly 300 can be connected to one or more first openings 302 , that is, each cavity 301 can perform dust extraction operations on one or more through holes 201 through one or more first openings 302 .

[0100] For example, in some specific embodiments, the cover plate 200 is provided with a plurality of through holes 201, and the plurality of through holes 201 are distributed on the cover plate 200 in a straight line and in sequence, and each through hole 201 corresponds to a channel 101 of a copper mouthpiece 100 and is connected thereto; the dust extraction component 300 includes a dust extraction tube body 310, and the dust extraction tube body 310 is a square tube structure, and a plurality of cavities 301 are formed inside the dust extraction tube body 310, and each cavity 301 has a second opening 303 and a plurality of first openings 302, and the dust extraction tube body 310 is assembled on the cover plate 200. On the other hand, the length direction of the dust extraction tube body 310 is arranged along the distribution direction of the multiple through holes 201, wherein the spacing between adjacent first openings 302 is consistent with the spacing between adjacent through holes 201, so that each first opening 302 of the dust extraction tube body 310 faces a corresponding through hole 201; the suction device 500 is used to connect the second openings 303 of each cavity 301 of the dust extraction tube body 310, so that the multiple first openings 302 of each cavity 301 can perform dust extraction operations on the through hole 201 they are facing and the channel 101 of the connected copper mouthpiece 100.

[0101] 4 and 8 , in some embodiments, the copper nozzle 100 includes a copper nozzle body 110 and a mounting portion 120 . The copper nozzle body 110 has a channel 101 . The mounting portion 120 is connected to the copper nozzle body 110 and is disposed on the first end surface 210 .

[0102] The copper nozzle body 110 may be a copper pipe section, the interior of which forms a hollow channel 101. The mounting portion 120 may be, but is not limited to, a mounting block, a mounting bracket, a mounting rod, a mounting plate, etc. The mounting portion 120 may be disposed on the outer wall of the copper nozzle body 110, and the copper nozzle body 110 and the mounting portion 120 may be integrally formed; alternatively, the copper nozzle body 110 may be fixed to the mounting portion 120 by screwing, clamping, welding, or the like.

[0103] The mounting portion 120 may be assembled to the first end surface 210 of the cover plate 200 by means of fasteners, or may be fixed to the first end surface 210 by means of clamping or welding.

[0104] For example, in some specific embodiments, the copper mouthpiece 100 includes a mounting base in the shape of a rectangular block, and a copper pipe section arranged in the middle of the mounting base and integrally formed with the mounting base, a plurality of lock holes are opened on the mounting base, and fixing holes corresponding to the lock holes are opened on the cover plate 200, and the fixing holes can be distributed around the corresponding through holes 201; the mounting base is abutted against the first end face 210, the channel 101 of the copper pipe section and the through hole 201 are connected, and each lock hole is connected to the corresponding fixing hole, and fasteners are used to pass through the lock holes and the fixing holes in sequence to achieve the purpose of fixing the mounting base on the first end face 210 and connecting the channel 101 to the through hole 201. It can be understood that the connection method of fixing the mounting base to the first end face 210 using fasteners is more stable than the connection method of directly welding the copper nozzle piece 100 to the first end face 210, so that the copper nozzle piece 100 has a better pressing effect on the welding object 2000, and the compressed welding object has a smaller risk of weld collapse during welding, thereby improving the welding effect.

[0105] Please refer to FIG. 1 , FIG. 2 and FIG. 5 . In some embodiments, the dust extraction device 1000 further includes a control component 400 . The control component 400 is disposed on the cover plate 200 . The control component 400 is configured to control the opening and closing of the second opening 303 .

[0106] It can be understood that the control component 400 is used to control the opening and closing of the second opening 303. When the control component 400 controls the second opening 303 to be turned on, the suction device 500 can form a negative pressure on the cavity 301 through the second opening 303, so that the first opening 302 can perform dust extraction operations on the through hole 201; when the control component 400 controls the second opening 303 to be blocked, the suction device 500 is not connected to the first opening 302.

[0107] Specifically, the control component 400 may include a driving structure and a blocking structure, and the driving structure is used to drive the blocking structure to move to block or open the second opening 303; or, the control component 400 may also include a manual adjustment structure 321, and the manual adjustment structure 321 can be movably set on the dust extraction component 300, and the second opening 303 can be blocked or opened through manual adjustment movement.

[0108] It should be understood that when the dust extraction component 300 has multiple cavities 301, that is, the dust extraction component 300 has multiple second openings 303, therefore, the number of control components 400 should also be multiple, and each control component 400 controls the opening and closing of the corresponding second opening 303 respectively.

[0109] In this way, the control component 400 can control the opening and closing of the second opening 303. When the dust extraction component 300 has multiple cavities 301, the control component 400 can be used to conduct the second opening 303 of the cavity 301 where the dust extraction operation needs to be performed, and to isolate the second opening 303 of the cavity 301 where the dust extraction operation does not need to be performed, so as to adjust the negative pressure value of the cavity 301 where the dust extraction operation needs to be performed, thereby improving the dust extraction effect of the corresponding first opening 302.

[0110] Please refer to Figures 1, 5 and 9. In some embodiments, the control component 400 includes a blocking member 410 and a driving member 420. The output end of the driving member 420 is connected to the blocking member 410. The driving member 420 is configured to drive the blocking member 410 to move to open or block the second opening 303.

[0111] Among them, the blocking member 410 can be but is not limited to a blocking block, a blocking ball, a blocking plate, etc.; the blocking member 410 can be set on the dust extraction component 300, and can be moved to block the second opening 303 or moved out from the second opening 303 by the drive member 420; or, the blocking member 410 can be set between the second opening 303 of the dust extraction component 300 and the suction device 500, and can be moved to block or connect the pipe connected between the second opening 303 and the suction device 500 by the drive member 420.

[0112] The driving member 420 may be, but is not limited to, a driving cylinder, a driving hydraulic cylinder, a driving motor, etc. The driving member 420 may be fixed by an external mounting structure, or may be mounted and fixed on the cover plate 200 .

[0113] In this configuration, the driving member 420 is used to drive the blocking member 410 to move, so that the blocking member 410 can move to block the second opening 303 or move to open the second opening 303 , thereby achieving the purpose of controlling the opening and closing of the second opening 303 .

[0114] Please refer to Figures 1, 9 and 10. In some embodiments, the control component 400 also includes a connecting member 430, which is provided with a connecting hole 431 and an insertion slot 432. The connecting hole 431 is connected to the second opening 303, and the second opening 303 is connected to the suction device 500 through the connecting hole 431. The insertion slot 432 intersects with the connecting hole 431; the blocking member 410 is a paddle, and the driving member 420 is configured to drive the paddle to move to insert into the insertion slot 432 and block the connecting hole 431.

[0115] Among them, the connecting member 430 can be but is not limited to a connecting joint, a connecting block, a connecting bracket, etc.; the connecting member 430 can be fixedly assembled through an external fixed structure, or the connecting member 430 can also be assembled on the cover plate 200 through a mounting bracket.

[0116] The connecting hole 431 and the insertion groove 432 opened on the connecting member 430 intersect with each other, that is, the depth direction of the insertion groove 432 intersects with the depth direction of the connecting hole 431. When the paddle moves to insert into the insertion groove 432, the paddle can block the connecting hole 431 along the depth direction intersecting with the connecting hole 431, thereby achieving the purpose of blocking the connecting hole 431, and then producing the effect of blocking the second opening 303.

[0117] For example, the connecting member 430 is taken as an example to illustrate the connecting joint. The connecting joint includes a joint seat 4301 and two joint tubes 4302 sealed and connected on opposite side surfaces of the joint seat 4301. A connecting hole 431 is provided on the joint seat 4301 to connect the two joint tubes 4302. An insertion groove 432 is also provided on the joint seat 4301. The depth direction of the insertion groove 432 is perpendicular to the depth direction of the connecting hole 431. It should be understood that the suction device 500 and the second opening 303 of the dust extraction assembly 300 can be connected through a pipeline. Therefore, the connecting joint can be set on the pipeline between the suction device 500 and the second opening 303. One of the joint pipes 4302 of the connecting joint is connected to the suction device 500 through the pipeline, and the other joint pipe 4302 of the connecting joint passes through; the driving member 420 can be a driving cylinder, and the piston of the driving cylinder is connected to the paddle. When the paddle is driven to insert into the insertion groove 432, the paddle can cut off the connecting hole 431, so that the joint pipes 4302 on both sides are blocked, thereby achieving the purpose of blocking the second opening 303.

[0118] The above-mentioned paddle can be but not limited to a circular paddle, a rectangular paddle, etc. It can be understood that the surface area of ​​the paddle is greater than or equal to the cross-sectional area of ​​the connecting hole 431, so that the paddle can completely block the connecting hole 431 when inserted into the insertion groove 432.

[0119] With this arrangement, the driving member 420 can drive the paddle to block the connecting hole 431 , so that the paddle blocks the second opening 303 and the air suction device 500 at the connecting hole 431 , thereby achieving the purpose of blocking the second opening 303 .

[0120] For example, in some specific embodiments, a plurality of through holes 201 are provided on the cover plate 200, a plurality of copper nozzles 100 are assembled on the first end surface 210 of the cover plate 200, the mounting portion 120 of the copper nozzle 100 is tightly connected to the second end surface 220 by a fastener, and the channel 101 on the copper nozzle body 110 of the copper nozzle 100 is connected to the corresponding through hole 201; the plurality of through holes 201 are distributed on the cover plate 200 and form a plurality of rows of hole groups, and each row of hole groups is provided with at least one dust extraction tube body 310 on at least one side of the distribution direction of the second end surface 220; the dust extraction tube body 310 is fastened by The parts are assembled on the cover plate 200, and the cover piece is assembled on the dust extraction tube body 310 through fasteners, and the opening 311 of the covering part is formed so that the other part of the exposed opening 311 forms a second opening 303 facing the corresponding through hole 201; the second opening 303 can be connected to a joint pipe 4302 of the connecting part 430 through a pipeline, and the other joint pipe 4302 of the connecting part 430 is connected to the suction device 500 through a pipeline. The connecting hole 431 can be blocked by driving the paddle to be inserted into the insertion groove 432 of the joint seat 4301 by driving the cylinder to achieve the purpose of blocking the opening 311.
