Description

Technical Field

[0001] This application relates to the field of welding technology, and more particularly to a dust extraction device and a battery production line. Background Technology

[0002] Welding technology is widely used in fields such as machinery and electronics. It is a processing technology that joins metal parts by heating, high temperature or high pressure.

[0003] During battery production, the terminals of individual battery cells typically need to be welded to conductive connecting pieces. This welding process generates fumes and slag; if these are not removed promptly, they can negatively impact the welding process, potentially leading to problems such as incomplete welds.

[0004] Application content

[0005] The purpose of this application is to provide a dust extraction device and a battery production line, which aims to improve the technical problems that affect the welding effect due to fumes and slag generated during welding.

[0006] The technical solution adopted in the embodiments of this application is:

[0007] In a first aspect, embodiments of this application provide a dust extraction device, which includes a copper nozzle, a cover plate, a dust extraction assembly, and a suction device. The copper nozzle is configured to abut against the welding area of ​​the object to be welded. The copper nozzle has a through channel. The cover plate has a through hole and a second end face opposite to the first end face. The copper nozzle is disposed on the first end face, and the channel is connected to the through hole. The dust extraction assembly is disposed on the second end face. The interior of the dust extraction assembly forms a cavity with a first opening and a second opening. The first opening faces the through hole, and the suction device is connected to the second opening.

[0008] The technical solutions described in this application have at least the following technical effects or advantages:

[0009] The dust extraction device provided in this application embodiment has a copper nozzle set on the first end face of a cover plate and a dust extraction assembly set on the second end face of the cover plate. The copper nozzle presses against the object to be welded and exposes the welding area of ​​the object to be welded. During the welding operation, fumes and slag generated will splash in the channel of the copper nozzle or pass through the channel and splash to the second end face of the cover plate. The suction device can form a negative pressure on the cavity of the dust extraction assembly through the second port. The dust extraction assembly set on the second end face can adsorb fumes, slag and other impurities inside the copper nozzle or on the second end face through the first port, and can timely discharge fumes, slag and other impurities, thereby reducing the amount of fumes, slag and other impurities remaining on the copper nozzle and the second end face, and thus reducing the impact of fumes, slag and other impurities on the welding effect.

[0010] In some embodiments, the dust extraction assembly includes a dust extraction tube body and a cover. The dust extraction tube body is disposed on a second end face, and a cavity is formed inside the dust extraction tube body. An opening and a second through-hole are provided on the dust extraction tube body. The cover is disposed on the dust extraction tube body and configured to block part of the opening to form a first through-hole.

[0011] By adopting the above technical solution, the dust extraction pipe body is set on the second end face, and the sealing member is set on the dust extraction pipe body and the opening of the sealed part is sealed, so that the other part of the opening is exposed and forms a first passage for adsorbing impurities such as smoke and welding slag. The suction device can form a negative pressure on the cavity of the dust extraction pipe body through the second passage, and then perform dust extraction operation at the through hole through the first passage.

[0012] In some embodiments, either the dust extraction tube body or the cover has an adjustment structure, and the other of the dust extraction tube body or the cover has a connection structure configured to be connected to any part of the adjustment structure.

[0013] By adopting the above technical solution, the purpose of assembling the cover on the dust extraction pipe is achieved by connecting the connecting structure to the adjusting structure. At the same time, by changing the position of the connecting structure connected to the adjusting structure, the area of ​​the cover sealing the opening can be adjusted, thereby adjusting the area of ​​the first opening and thus adjusting the air volume of the first opening to improve the dust extraction effect.

[0014] In some embodiments, the adjustment structure is an oblong hole, and the connection structure is a mounting hole.

[0015] By adopting the above technical solution, the mounting hole can be aligned with any point of the oblong hole, and the cover can be assembled onto the dust extraction pipe body using fasteners, thereby realizing the installation and position adjustment of the cover.

[0016] In some embodiments, the cover plate has a chamfer at the connection point between the through hole and the second end face.

[0017] By adopting the above technical solution, the cavity of the dust extraction component is under negative pressure due to the suction device connected to the second port. By setting a chamfer at the connection position between the second end face and the through hole, the airflow formed by the negative pressure in the cavity from the inside of the copper nozzle to the first port is avoided by the chamfer, thereby improving the airflow velocity and flow rate, and thus effectively improving the dust extraction effect in the channel of the copper nozzle.

[0018] In some embodiments, the cover plate has multiple through holes, and there are multiple copper nozzles. The multiple copper nozzles are disposed on the first end face and are respectively connected to the corresponding through holes. The dust extraction assembly has several cavities inside, and the first opening of each cavity faces the corresponding through hole.

[0019] By adopting the above technical solution, when there are multiple copper nozzles, multiple through holes are also opened on the cover plate so that multiple copper nozzles can be connected to the corresponding through holes. At the same time, several cavities are formed inside the dust extraction component, and the first opening of each cavity faces the through hole. This ensures that when welding is performed in any copper nozzle, there is a first opening facing the corresponding through hole. The dust extraction component is used to perform dust extraction operation on the copper nozzle connected to the through hole through the first opening.

[0020] In some embodiments, the dust extraction assembly has a plurality of first ports, and each cavity is connected to at least one first port.

[0021] By adopting the above technical solution, each cavity of the dust extraction component can be connected to one or more first ports, that is, each cavity can perform dust extraction operation on one or more through holes through one or more first ports.

[0022] In some embodiments, the copper nozzle component includes a copper nozzle body and a mounting portion. The copper nozzle body has a channel, and the mounting portion is connected to the copper nozzle body and disposed on a first end face.

[0023] By adopting the above technical solution, the copper nozzle body can be installed on the first end face through the mounting part, so that the channel of the copper nozzle body is connected with the through hole, making the connection between the copper nozzle body and the first end face more stable and reducing the probability of the copper nozzle body getting stuck, thereby improving the welding effect.

[0024] In some embodiments, the dust extraction device further includes a control component disposed on the cover plate, the control component being configured to control the opening and closing of the second port.

[0025] By adopting the above technical solution, the control component can control the opening and closing of the second port. When the dust extraction component has multiple cavities, the control component can be used to open the second port of the cavity that needs to perform dust extraction operation and close the second port of the cavity that does not need to perform dust extraction operation, thereby adjusting the negative pressure value of the cavity that needs to perform dust extraction operation to improve the dust extraction effect of the corresponding first port.

[0026] In some embodiments, the control component includes a blocking element and a driving element, the output of which is connected to the blocking element, and the driving element is configured to move the blocking element to open or block the second port.

[0027] By adopting the above technical solution, the driving component is used to move the blocking component, so that the blocking component can move to block the second port or move to open the second port, thereby achieving the purpose of controlling the opening and closing of the second port.

[0028] In some embodiments, the control component further includes a connector having a connection hole and an insertion slot. The connection hole is connected to a second port, which is connected to a suction device through the connection hole. The insertion slot intersects with the connection hole. The blocking component is a paddle, and the driving component is configured to move the paddle to the insertion slot and block the connection hole.

[0029] By adopting the above technical solution, the driving component can drive the paddle to seal the connection hole, so that the paddle blocks the second port and the suction device at the connection hole, thereby achieving the purpose of sealing the second port. Secondly, embodiments of this application also provide a battery production line, including the dust extraction device as described above.

[0030] The technical solutions described in this application have at least the following technical effects or advantages:

[0031] The battery production line provided in this application includes the aforementioned dust extraction device. With the dust extraction device able to promptly remove smoke, welding slag, and other impurities to reduce their impact on the welding effect, the battery production line produces products of higher quality.

[0058] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0059] With the continuous expansion of market demand for batteries, the production and use of battery products are also constantly increasing. During the battery production and assembly process, the battery terminals usually need to be welded to conductive connecting pieces. Welding is a processing technology that joins metal parts by heating, high temperature, or high pressure. During the welding process, fumes and welding slag are generated. If these impurities are not removed in time, they will accumulate around the welding point, affecting the welding work and potentially causing problems such as incomplete welds or weld collapse, thus impacting the welding effect.

[0060] Based on the above considerations, in order to solve the technical problem that the welding effect may be affected by the failure to remove the fumes, slag and other impurities generated during welding in a timely manner, 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 with the first opening facing the through hole, and the copper nozzle 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 around the welding station, and the copper nozzle is placed against the welding area of ​​the object to be welded. During the welding operation, the fumes, slag and other impurities generated during welding will accumulate in the channel of the copper nozzle or pass through the channel of the copper nozzle and splash to the second end face. The suction device can create 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 be directed towards the through hole to perform dust extraction operation, thereby timely removing the fumes, slag and other impurities generated during welding, thereby reducing the impact of fumes, slag and other impurities on the welding operation, and thus achieving the purpose of improving the welding effect.

[0061] The dust extraction device disclosed in this application can be used to extract dust during the welding operation of terminals and conductive connecting pieces in the battery production process, and can also be used for dust extraction during the welding process of other components.

[0062] For ease of explanation, the following embodiments will be described using the dust extraction device in the welding process of a battery production line as an example.

[0063] The dust extraction device provided in the embodiments of this application will now be described.

[0064] Please refer to Figures 1 to 5 This application provides a dust extraction device 1000, including a copper nozzle 100, a cover plate 200, a dust extraction assembly 300, and a suction device 500. The copper nozzle 100 is configured to abut against the welding area of ​​the object to be welded 2000. The copper nozzle 100 has a through channel 101. The cover plate 200 has a through hole 201 and a first end face 210 and a second end face 220 disposed opposite to each other. The copper nozzle 100 is disposed on the first end face 210. The channel 101 is connected to the through hole 201. The dust extraction assembly 300 is disposed on the second end face 220. The interior of the dust extraction assembly 300 forms a cavity 301 with a first opening 302 and a second opening 303. The first opening 302 faces the through hole 201. The suction device 500 is connected to the second opening 303.

[0065] The cover plate 200 is a tooling component used for assembly and connection. The cover plate 200 is used to support the assembly of multiple parts such as the copper nozzle part 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 for dust extraction operation of the welding process of the battery production line.

[0066] Specifically, the cover plate 200 has a plate-like structure. Therefore, the first end face 210 and the second end face 220 of the cover plate 200 refer to the two opposite end faces in the thickness direction of the cover plate 200.

[0067] The cover plate 200 has a through hole 201, which is used to communicate with the channel 101 of the copper nozzle 100. The number of through holes 201 can be one or more, and the arrangement of through holes 201 can be in a straight line or in an arc, etc.

[0068] The copper nozzle 100 is used to abut against the welding area of ​​the object to be welded 2000, so that the channel 101 of the copper nozzle 100 exposes the welding area of ​​the object to be welded 2000. This allows welding equipment to pass through the through hole 201 and the channel 101 of the copper nozzle 100 and perform welding operations on the welding area of ​​the object to be welded 2000. Understandably, the welding area of ​​the object to be welded 2000 refers to the area of ​​the object to be welded 2000 where the welding operation is specifically performed; the copper nozzle 100 is abutted against this welding area of ​​the object to be welded 2000, so that the welding area is exposed through the channel 101 of the copper nozzle 100, facilitating welding operations by external welding equipment.

[0069] When the dust extraction device 1000 is used on the battery production line to perform dust extraction operation on the welding of conductive connecting pieces, the copper nozzle 100 is used to abut against the welding area of ​​the conductive connecting piece so that the conductive connecting piece and the electrode of the battery cell are tightly attached.

[0070] The copper nozzle 100 is disposed on the first end face 210 of the cover plate 200. Specifically, the copper nozzle 100 can be assembled on the cover plate 200 by fasteners, or it can be fixedly installed on the cover plate 200 by snap-fit, welding or other methods.

[0071] The channel 101 of the copper nozzle 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 100 on the second end face 220 side of the cover plate 200 and perform welding operations on the welding area of ​​the object to be welded 2000. Impurities generated during welding can fly from the channel 101 of the copper nozzle 100 through the through hole 201 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 extract impurities through the first port 302 toward the through hole 201, so that impurities can be extracted in time.

[0072] Specifically, the dust extraction assembly 300 may include, but is not limited to, a dust extraction pipe, a dust extraction box, a dust extraction adapter, etc.; the interior of the dust extraction assembly 300 forms a cavity 301. It can be understood that the interior of the dust extraction assembly 300 may specifically form one cavity 301, or may form multiple independent cavities 301, and each cavity 301 has a first port 302 and a second port 303. The second port 303 is used to connect to the suction device 500 so that the cavity 301 forms a negative pressure, and the first port 302 is used to perform dust extraction operation towards the through hole 201.

[0073] The aforementioned suction device 500 can be a blower, a negative pressure device, an induced draft fan, etc. The suction device 500 is used to perform suction operation on the cavity 301 of the dust extraction component 300 through the second port 303, so that the cavity 301 of the dust extraction component 300 forms a negative pressure, thereby enabling the first port 302 of the dust extraction component 300 to achieve the purpose of suctioning and removing impurities at the through hole 201.

[0074] The dust extraction device 1000 provided in this embodiment of the application has a copper nozzle 100 disposed on the first end face 210 of a cover plate 200, and a dust extraction assembly 300 disposed on the second end face 220 of the cover plate 200. The copper nozzle 100 presses against the object to be welded 2000 and exposes the welding area of ​​the object to be welded 2000. When welding is performed on the welding area, the fumes, 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 face 220 of the cover plate 200. The suction device 500 can... The second port 303 can create a negative pressure in the cavity 301 of the dust extraction component 300. The cavity 301 with negative pressure in the dust extraction component 300 can adsorb dust, 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 port 302. This can timely discharge dust, welding slag and other impurities, thereby reducing the amount of dust, welding slag and other impurities remaining on the copper nozzle 100 and the second end face 220, and thus reducing the impact of dust, welding slag and other impurities on the welding effect, so as to improve the welding effect.

[0075] Please refer to Figures 1 to 3 , Figure 5 and Figure 6 In some embodiments, the dust extraction assembly 300 includes a dust extraction tube 310 and a cover 320. The dust extraction tube 310 is disposed on the second end face 220. A cavity 301 is formed inside the dust extraction tube 310. An opening 311 and a second through-hole 303 are provided on the dust extraction tube 310. The cover 320 is disposed on the dust extraction tube 310 and is configured to block part of the opening 311 to form a first through-hole 302.

[0076] Understandably, the dust extraction pipe body 310 can be, but is not limited to, a square pipe structure, a round pipe structure, etc.; wherein, the dust extraction pipe body 310 can be a straight pipe or an arc-shaped pipe, or include both straight pipe sections and arc-shaped sections. The dust extraction pipe body 310 can be a metal pipe body, an alloy pipe body, etc., such as an aluminum alloy pipe body, etc.

[0077] The dust extraction pipe body 310 is disposed on the second end face 220. Specifically, the dust extraction pipe body 310 can be assembled onto the second end face 220 by fasteners, or the dust extraction pipe body 310 can also be fixedly installed onto the second end face 220 by snap-fit, welding, or other methods. When the dust extraction pipe body 310 is assembled onto the second end face 220 by fasteners, the dust extraction pipe body 310 can be removed by loosening the fasteners, thereby making it easier to perform maintenance operations on the dust extraction pipe body 310, or to replace the dust extraction pipe body 310.

[0078] The dust extraction pipe body 310 has a cavity 301 inside. Specifically, the cavity 301 can be directly formed inside the dust extraction pipe body 310. The dust extraction pipe body 310 has an opening 311 and a first through-hole 302, and the opening 311 and the first through-hole 302 are respectively connected to the cavity 301. Alternatively, the dust extraction pipe body 310 has a slot. When the dust extraction pipe body 310 is assembled on the second end face 220, the second end face 220 can cover part of the slot, so that the second end face 220 surrounds the slot to form a cavity 301, and the part of the slot not covered by the second end face 220 forms the opening 311.

[0079] The cover 320 is used to seal part of the opening 311, so that the other part of the unsealed opening 311 forms a first passage 302. Specifically, the cover 320 can be, but is not limited to, a cover plate 200, a blocking block, etc. The cover 320 can be fixedly installed on the dust extraction pipe body 310, or the cover 320 can be movably connected to the dust extraction pipe body 310. When the cover 320 is movably connected to the dust extraction pipe body 310, specifically, the cover 320 can be detachably connected to the dust extraction pipe body 310. When it is necessary to clean and maintain the cavity 301 of the dust extraction pipe body 310, the cover 320 can be removed to completely expose the opening 311, thereby making it easier to perform cleaning and maintenance operations inside the dust extraction pipe body 310.

[0080] With this configuration, the dust extraction pipe 310 is positioned on the second end face 220, and the cover 320 is positioned on the dust extraction pipe 310, sealing part of the opening 311. This exposes another part of the opening 311, forming a first through-hole 302 for adsorbing impurities such as fumes and welding slag. The suction device 500 can create negative pressure on the cavity 301 of the dust extraction pipe 310 through the second through-hole 303, thereby enabling dust extraction through the through-hole 201 via the first through-hole 302. Simultaneously, by connecting the suction device 500 to the second through-hole 303 of the dust extraction assembly 300, the cavity 301 of the dust extraction assembly 300 can directly extract dust from the through-hole 201 and the channel 101 of the copper nozzle 100 through the first through-hole 302. This reduces the use of ductwork for air guidance, thereby reducing the obstruction of gas flow caused by duct bends and transitions, and optimizing the dust removal velocity to achieve the purpose of optimizing the dust extraction effect.

[0081] Please refer to Figures 5 to 7 In some embodiments, either the dust extraction tube 310 or the cover 320 has an adjustment structure 321, and the other of the dust extraction tube 310 or the cover 320 has a connection structure 312 configured to be connected to either of the adjustment structure 321.

[0082] Specifically, the adjustment structure 321 can be installed on the dust extraction pipe body 310, and the connecting structure 312 can be installed on the cover 320; or, the adjustment structure 321 can be installed on the cover 320, and the connecting structure 312 can be installed on the dust extraction pipe body 310.

[0083] Understandably, the adjusting structure 321 can be connected to the connecting structure 312, and the connecting structure 312 can be connected to any part of the adjusting structure 321. That is, the connection position between the connecting structure 312 and the adjusting structure 321 can be located at any part of the adjusting structure 321. Thus, the cover 320 can adjust its position on the dust extraction pipe body 310 by adjusting the connection position between the adjusting structure 321 and the connecting structure 312, thereby adjusting the area of ​​the cover 320 blocking the opening 311, so as to adjust 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.

[0084] The aforementioned adjustment structure 321 can be a waist-shaped hole, and the connecting structure 312 can be a connecting hole 431. When the cover 320 is assembled onto the dust extraction pipe body 310, the cover 320 can be pressed against the dust extraction pipe body 310, and the connecting hole 431 is in relative communication with the waist-shaped hole. Fasteners are used to fasten the connection between the waist-shaped hole and the connecting block to achieve the purpose of assembling the cover 320 onto the dust extraction pipe body 310. During the process of the connecting hole 431 being in relative communication with 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 320 and the dust extraction pipe body 310 until the position of the cover 320 relative to the dust extraction pipe body 310 is adjusted to the correct position, and then the installation is completed using fasteners.

[0085] Alternatively, the aforementioned adjustment structure 321 can be multiple adjustment holes, which can be arranged in any direction, such as along the length or width of the opening 311. The connection structure 312 can be a connection hole 431. When the cover 320 is assembled onto the dust extraction pipe 310, the cover 320 can be abutted against the dust extraction pipe 310, and the connection hole 431 can be selected to connect one or more of the multiple adjustment holes to each other as needed, thereby adjusting the position of the cover 320 to be connected to the dust extraction pipe 310. Finally, the installation can be completed using fasteners.

[0086] Alternatively, both the adjustment structure 321 and the connecting structure 312 described above can be oblong holes; or both the adjustment structure 321 and the connecting structure 312 described above can be a group of holes composed of multiple round holes; or one of the adjustment structure 321 and the connecting structure 312 described above can be an oblong hole, and the other can be a group of holes composed of multiple round holes.

[0087] With this configuration, by connecting the connecting structure 312 to the adjusting structure 321, the purpose of assembling the cover 320 onto the dust extraction pipe body 310 is achieved. At the same time, by changing the position of the connecting structure 312 connected to the adjusting structure 321, the area of ​​the cover plate 200 and the cover 320 blocking the opening 311 can be adjusted, thereby adjusting the area of ​​the first opening 302 and thus adjusting the air volume of the first opening 302 to improve the dust extraction effect.

[0088] Please refer to Figure 6 In some embodiments, the adjustment structure 321 is an oblong hole, and the connection structure 312 is a mounting hole.

[0089] Among them, the waist-shaped hole refers to a hole shape formed by the combination of semi-circular holes at both ends and an elongated hole in the middle; the mounting hole refers to a round hole for fasteners to pass through. Specifically, the number of waist-shaped holes is set relative to the number of mounting holes, and there can be one or more waist-shaped holes, so the number of mounting holes can also be one or more.

[0090] The mounting hole can be positioned opposite to and connected to the waist-shaped hole, and the mounting hole can be adjusted along the length of the waist-shaped hole to adjust the relative position of the cover 320 and the dust extraction pipe 310.

[0091] Specifically, the waist-shaped hole can be formed on the cover 320, and the mounting hole can be formed on the dust extraction pipe 310; or, the waist-shaped hole can be formed on the dust extraction pipe 310, and the mounting hole can be formed on the cover 320.

[0092] With this configuration, the mounting hole can be aligned with any point of the waist-shaped hole, and the cover 320 can be assembled onto the dust extraction pipe body 310 using fasteners. This allows for the installation and position adjustment of the cover 320, thereby adjusting the area of ​​the sealing opening 311 by the cover 320. This adjustment is used to change the size of the first opening 302 to optimize the dust extraction effect.

[0093] For example, in some specific embodiments, the dust extraction pipe 310 can be a square tube. When the dust extraction pipe 310 is assembled with the second end face 220, a rectangular opening 311 is provided on the side wall of the dust extraction pipe 310 that intersects with the second end face 220 and is close to the through hole 201. One edge of the opening 311 is flush with the second end face 220. The cover 320 can be a rectangular cover plate, the length of which is greater than the length of the opening 311. The cover plate has a waist-shaped hole, the length direction of which is arranged along the width direction of the cover plate. There are multiple waist-shaped holes, which are respectively opened at opposite ends of the waist-shaped holes in the length direction. The dust extraction pipe 310 has a mounting hole, which is also multiple. The mounting holes are respectively opened on opposite sides of the dust extraction pipe 310 in the length direction of the opening 311, and the mounting holes and waist-shaped holes are respectively corresponding to each other. During installation, the cover plate is placed against the dust extraction pipe body 310, and the oblong hole of the cover plate is aligned with the corresponding mounting hole of the dust extraction pipe body 310. At this time, the cover plate can cover the opening 311. That is, the opening 311 forms a first passage 302 in the width direction from the side edge flush with the second end face 220 to the edge of the cover plate. Then, the cover plate can be moved and adjusted along the length direction of the oblong hole to adjust the range of the first passage 302, thereby optimizing the dust extraction effect. After the adjustment is completed, the bolt is passed through the oblong hole and the mounting hole and the nut is tightened to connect the cover plate and the dust extraction pipe body 310.

[0094] Please refer to Figures 2 to 5 In some embodiments, the cover plate 200 has a chamfer 230 at the connection position between the through hole 201 and the second end face 220.

[0095] Understandably, a chamfer of 230 refers to the process of cutting the edges of a workpiece into a certain bevel. Specifically, the chamfer of 230 can be a round chamfer of 230 or a straight chamfer of 230.

[0096] With this configuration, the cavity 301 of the dust extraction component 300 is under negative pressure due to the suction device 500 connected to the second port 303. The negative pressure cavity 301 can then perform dust extraction at the through hole 201 through the first port 302. The airflow in the channel 101 of the through hole 201 and the copper nozzle 100 is formed by the negative pressure adsorption of the first port 302. By setting a chamfer 230 at the connection position between the second end face 220 and the inner wall of the through hole 201, the chamfer 230 can guide the airflow when it flows out of the through hole 201, so that the airflow can flow more smoothly into the first port 302 to form a dust extraction effect. The chamfer 230 can improve the flow rate and flow volume of the airflow from the channel 101 of the copper nozzle 100 to the first port 302, thereby effectively improving the dust extraction effect in the channel 101 of the copper nozzle 100.

[0097] Please refer to Figures 2 to 5 In some embodiments, the cover plate 200 has multiple through holes 201, and there are multiple copper nozzles 100. The multiple copper nozzles 100 are disposed on the first end face 210 and are respectively connected to the corresponding through holes 201. The dust extraction assembly 300 has a number of cavities 301 inside, and the first opening 302 of each cavity 301 faces the corresponding through hole 201.

[0098] Understandably, the cover plate 200 has multiple through holes 201, which can be arranged sequentially at intervals along any direction; or, the multiple through holes 201 can be arranged sequentially at intervals along any arc; or, the multiple through holes 201 can be distributed in an array on the cover plate 200. When the multiple through holes 201 are distributed in an array on the cover plate 200, the dust extraction assembly 300 can include multiple dust extraction pipes 310, with one dust extraction pipe 310 provided on one side of each column of through holes 201, and the first opening 302 of the dust extraction pipe 310 facing each corresponding through hole 201 in that column.

[0099] There are multiple copper nozzle components 100. Specifically, the number of copper nozzle components 100 can be the same as the number of through holes 201, and the channel 101 of each copper nozzle component 100 is connected to the corresponding through hole 201; or, the number of copper nozzle components 100 can be less than the number of through holes 201.

[0100] The dust extraction component 300 has a number of cavities 301 inside. Specifically, the dust extraction component 300 may have one cavity 301 inside, or multiple cavities 301 inside.

[0101] Each cavity 301 has a first opening 302 facing the corresponding through hole 201. Specifically, each cavity 301 has a first opening 302, and each first opening 302 of each cavity 301 is used to perform dust extraction operation on a through hole 201 and a connected copper nozzle 100; or, each cavity 301 may have multiple first openings 302, and each first opening 302 can perform dust extraction operation on a through hole 201 and a connected copper nozzle 100.

[0102] With this configuration, when there are multiple copper nozzle components 100, multiple through holes 201 are also opened on the cover plate 200 so that multiple copper nozzle components 100 can be connected to the corresponding through holes 201. Welding operations can be performed simultaneously through multiple through holes 201 and the channels 101 of the connected copper nozzle components 100. At the same time, the dust extraction component 300 forms several cavities 301 inside, and the first opening 302 of each cavity 301 faces the through hole 201, so that when welding is performed in any copper nozzle component 100, there is a first opening 302 facing the corresponding through hole 201. The dust extraction component 300 performs dust extraction operation on the copper nozzle component 100 connected to the through hole 201 through the first opening 302.

[0103] Please refer to Figures 2 to 5 and Figure 7 In some embodiments, the dust extraction assembly 300 has a plurality of first ports 302, and each cavity 301 is connected to at least one first port 302.

[0104] Understandably, when the dust extraction assembly 300 includes a dust extraction pipe body 310, one or more cavities 301 can be formed within the dust extraction pipe body 310, and one or more first openings 302 are provided on the dust extraction pipe body 310; each cavity 301 has at least one first opening 302. Specifically, one cavity 301 may have one first opening 302, through which the cavity 301 is connected to the outside; or, one cavity 301 may have multiple first openings 302, through which the cavity 301 is connected to the outside, and the multiple first openings 302 can face multiple through holes 201 respectively, so that one cavity 301 can perform dust extraction operation on multiple through holes 201 through multiple first openings 302.

[0105] Meanwhile, each cavity 301 has a second port 303, and the second port 303 of each cavity 301 is connected to the suction device 500 to form a negative pressure, so that dust extraction can be performed on the through hole 201 and the channel 101 of the copper nozzle 100 through the first port 302.

[0106] With this configuration, each cavity 301 of the dust extraction assembly 300 can be connected to one or more first ports 302, meaning that each cavity 301 can perform dust extraction operations on one or more through holes 201 through one or more first ports 302.

[0107] For example, in some specific embodiments, the cover plate 200 has multiple through holes 201, which are distributed along a straight line and spaced apart from each other. Each through hole 201 corresponds to and communicates with a channel 101 of a copper nozzle 100. The dust extraction assembly 300 includes a dust extraction tube 310, which has a square tube structure. The interior of the dust extraction tube 310 has multiple cavities 301, and each cavity 301 has a second opening 303 and multiple first openings 302. The dust extraction tube 310 is assembled on the cover plate 200. The dust extraction pipe body 310 is arranged along the distribution direction of multiple through holes 201 along its length direction. The spacing between adjacent first through holes 302 is the same as the spacing between adjacent through holes 201, so that each first through hole 302 of the dust extraction pipe body 310 faces a corresponding through hole 201. The suction device 500 is connected to the second through holes 303 of each cavity 301 of the dust extraction pipe body 310, so that the multiple first through holes 302 of each cavity 301 can perform dust extraction operation on the through hole 201 they face and the channel 101 of the connected copper nozzle 100.

[0108] Please refer to Figure 4 and Figure 8 In some embodiments, the copper nozzle 100 includes a copper nozzle body 110 and a mounting part 120. The copper nozzle body 110 has a channel 101, and the mounting part 120 is connected to the copper nozzle body 110 and disposed on the first end face 210.

[0109] The copper nozzle body 110 can be a copper tube segment, with a hollow channel 101 formed inside the copper tube segment. The mounting part 120 can be, but is not limited to, a mounting block, mounting bracket, mounting rod, mounting plate, etc.; the mounting part 120 can be set on the outer wall of the copper nozzle body 110, and the copper nozzle body 110 can be integrally formed with the mounting part 120; or, the copper nozzle body 110 can be fixed to the mounting part 120 by means of screwing, snap-fitting, welding, etc.

[0110] The mounting part 120 can be assembled to the first end face 210 of the cover plate 200 by fasteners, or it can be fixed to the first end face 210 by snap-fit ​​or welding.

[0111] For example, in some specific embodiments, the copper nozzle 100 includes a rectangular block-shaped mounting base and a copper tube segment integrally formed with the mounting base and located in the middle of the mounting base. The mounting base has multiple locking holes, and the cover plate 200 has fixing holes corresponding to the locking holes. 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 tube segment is connected to the through hole 201, and each locking hole is connected to the corresponding fixing hole. Fasteners are used to pass through the locking holes and fixing holes in sequence to fix the mounting base on the first end face 210, and the channel 101 is connected to the through hole 201. Understandably, 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 100 to the first end face 210. As a result, the copper nozzle 100 has a better pressing effect on the object to be welded 2000. The pressed object has a lower risk of weld collapse during welding, thereby improving the welding effect.

[0112] Please refer to Figure 1 , Figure 2 and Figure 5 In some embodiments, the dust extraction device 1000 further includes a control component 400 disposed on the cover plate 200, and the control component 400 is configured to control the opening and closing of the second port 303.

[0113] Understandably, the control component 400 is used to control the opening and closing of the second port 303. When the control component 400 controls the second port 303 to be open, the suction device 500 can form a negative pressure on the cavity 301 through the second port 303, so that the first port 302 can perform dust extraction operation at the through hole 201. When the control component 400 controls the second port 303 to be closed, the suction device 500 is not connected to the first port 302.

[0114] Specifically, the control component 400 may include a drive structure and a blocking structure, wherein the drive structure drives the blocking structure to move to block or open the second port 303; or, the control component 400 may also include a manual adjustment structure 321, which may be movably mounted on the dust extraction component 300, and the second port 303 may be blocked or opened by manual adjustment.

[0115] It should be understood that when the dust extraction component 300 has multiple cavities 301, that is, when the dust extraction component 300 has multiple second ports 303, the number of control components 400 should also be multiple, and each control component 400 controls the opening and closing of the corresponding second port 303.

[0116] With this configuration, the control component 400 can control the opening and closing of the second port 303. When the dust extraction component 300 has multiple cavities 301, the control component 400 can be used to open the second port 303 of the cavity 301 that needs to perform dust extraction and to close the second port 303 of the cavity 301 that does not need to perform dust extraction. This is to adjust the negative pressure value of the cavity 301 that needs to perform dust extraction and thus improve the dust extraction effect of the corresponding first port 302.

[0117] Please refer to Figure 1 , Figure 5 and Figure 9 In some embodiments, the control component 400 includes a blocking element 410 and a driving element 420, the output of which is connected to the blocking element 410, and the driving element 420 is configured to move the blocking element 410 to open or block the second port 303.

[0118] The sealing component 410 may be, but is not limited to, a sealing block, a sealing ball, a sealing plate, etc.; the sealing component 410 may be disposed on the dust extraction assembly 300 and may be moved to block the second opening 303 or moved out of the second opening 303 by the drive component 420; or, the sealing component 410 may be disposed between the second opening 303 of the dust extraction assembly 300 and the suction device 500 and may be moved to block or connect the pipe connecting the second opening 303 and the suction device 500 by the drive component 420.

[0119] The drive component 420 may be, but is not limited to, a drive cylinder, a drive hydraulic cylinder, a drive motor, etc. The drive component 420 can be fixed by an external mounting structure, or it can be mounted on the cover plate 200.

[0120] With this configuration, the driving component 420 is used to move the blocking component 410, so that the blocking component 410 can move to block the second port 303, or move to open the second port 303, thereby achieving the purpose of controlling the opening and closing of the second port 303.

[0121] Please refer to Figure 1 , Figure 9 and Figure 10 In some embodiments, the control component 400 further includes a connector 430, which has a connection hole 431 and an insertion slot 432. The connection hole 431 is connected to the second port 303, and the second port 303 is connected to the suction device 500 through the connection hole 431. The insertion slot 432 intersects with the connection hole 431. The blocking component 410 is a paddle, and the driving component 420 is configured to drive the paddle to move to the insertion slot 432 and block the connection hole 431.

[0122] The connector 430 may be, but is not limited to, a connector, a connector block, a connector bracket, etc. The connector 430 may be fixedly assembled by the fixing structure of the external device, or the connector 430 may be assembled on the cover plate 200 by the mounting bracket.

[0123] The connecting hole 431 and the insertion slot 432 on the connector 430 intersect, that is, the depth direction of the insertion slot 432 and the depth direction of the connecting hole 431 intersect. When the lever moves to insert the insertion slot 432, the lever can block the connecting hole 431 along the depth direction intersecting the connecting hole 431, thereby achieving the purpose of blocking the connecting hole 431, and thus producing the effect of blocking the second port 303.

[0124] For example, taking connector 430 as a connecting joint, the connecting joint includes a connector seat 4301 and two connector tubes 4302 that are sealed and connected to opposite sides of the connector seat 4301. The connector seat 4301 has a connecting hole 431 to connect the two connector tubes 4302. The connector seat 4301 also has an insertion groove 432, the depth direction of which is perpendicular to the depth direction of the connecting hole 431. It should be understood that the second port 303 of the suction device 500 and the dust extraction assembly 300 can be connected by a pipeline. Therefore, a connecting joint can be set on the pipeline between the suction device 500 and the second port 303. One of the connecting pipes 4302 is connected to the suction device 500 through the pipeline, and the other connecting pipe 4302 is connected to the suction device 500 through the pipeline. The driving component 420 can be a driving cylinder. The piston of the driving cylinder is connected to a paddle. When the paddle is driven to the insertion slot 432, the paddle can cut off the connecting hole 431, so that the connecting pipes 4302 on both sides are blocked, thereby achieving the purpose of blocking the second port 303.

[0125] The aforementioned paddle can be, but is 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 when the paddle is inserted into the insertion slot 432, it can completely block the connecting hole 431.

[0126] With this configuration, the drive unit 420 can drive the paddle to block the connection hole 431, so that the paddle blocks the second port 303 and the suction device 500 at the connection hole 431, thereby achieving the purpose of blocking the second port 303.

[0127] For example, in some specific embodiments, the cover plate 200 has multiple through holes 201, and the first end face 210 of the cover plate 200 is fitted with multiple copper nozzle parts 100. The mounting part 120 of the copper nozzle part 100 is tightly connected to the second end face 220 by fasteners. The channel 101 on the copper nozzle body 110 of the copper nozzle part 100 is connected to the corresponding through hole 201. The multiple through holes 201 are distributed on the cover plate 200 and form multiple rows of hole groups. At least one dust extraction pipe body 310 is provided on at least one side of the distribution direction of each row of holes on the second end face 220. The dust extraction pipe body 310 is fastened by fasteners. The component is assembled on the cover plate 200, and the cover plate is assembled on the dust extraction pipe body 310 by fasteners, and the opening 311 of the cover part is sealed so that the other part of the exposed opening 311 forms a second through hole 303 facing the corresponding through hole 201; the second through hole 303 can be connected to a connector pipe 4302 of the connector 430 through a pipe, and the other connector pipe 4302 of the connector 430 is connected to the suction device 500 through a pipe. By driving the cylinder to drive the paddle to insert into the insertion slot 432 of the connector seat 4301, the connection hole 431 can be blocked, so as to achieve the purpose of sealing the opening 311.

[0128] Please refer to Figure 1 This application also provides a battery production line 10, including the dust extraction device 1000 as described above.

[0129] The battery production line 10 provided in this application embodiment includes the aforementioned dust extraction device 1000.
