[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] During the ultrasonic welding process of the battery cell tabs, a large amount of dust and particulate matter is generated due to the vibration and friction of the welding head. This dust and particulate matter not only pollutes the working environment, but may also enter the battery cell and cause the separator to break down and short circuit, seriously affecting the quality and performance of the battery.

[0024] To reduce the impact of impurities such as dust and particulate matter, a dust removal device is provided in the relevant technology. The dust removal device has a dust hood connected to the welding head and capable of rising and falling with it. During welding, the dust hood covers the outside of the welding head and is connected to a suction device. The suction device removes dust or particulate matter from inside the dust hood.

[0025] However, the dust removal devices and welding head positions in related technologies are fixed, making it difficult to be compatible with various types of battery cells. To solve or improve the problem of dust removal devices in related technologies being incompatible with various types of battery cells, this utility model provides a dust removal device, welding equipment, and a battery cell production line.

[0026] The following is combined with Figures 1 to 6 This describes the dust removal device provided in the embodiments of the present invention.

[0027] Specifically, the dust removal device is used in the welding machine 4, and the dust removal device includes a first cover 1, a drive mechanism 2, and an adjustment mechanism 3.

[0028] The first cover 1 is used to cover the outside of the welding head 402 of the welding machine 4, and the first cover 1 can be directly or indirectly connected to the suction device. For example, the bottom end of the first cover 1 is provided with a mating interface so that at least part of the welding head 402 can enter and exit the first cover 1 through the mating interface. At the same time, the side wall of the first cover 1 is provided with a clearance opening communicating with the mating interface to allow the main shaft of the welding head 402 to pass through, so that when the welding head 402 enters the first cover 1 from the mating interface, the main shaft can be placed in the clearance opening.

[0029] The drive mechanism 2 and the adjustment mechanism 3 are connected, and one of the drive mechanism 2 and the adjustment mechanism 3 is connected to the first cover 1, while the other is used to connect to the body 401 of the welding machine 4.

[0030] For example, refer to Figures 1-6The diagram shows an example where the adjusting mechanism 3 is connected to the body 401, the driving mechanism 2 is connected to the adjusting mechanism 3, and the driving end 201 of the driving mechanism 2 is connected to the first cover 1. This example will be discussed in detail below. However, it is understood that the reverse is also possible, i.e., the driving mechanism 2 is connected to the body 401 of the welding machine 4, the driving end 201 of the driving mechanism 2 is connected to the adjusting mechanism 3, and the adjusting mechanism 3 is connected to the first cover 1.

[0031] The drive mechanism 2 is used to drive the first cover 1 to move along the moving direction of the welding head 402, so that the first cover 1 can move with the welding head 402. In actual use, the welding head 402 can move along the height direction of the welding machine 4, and correspondingly, the drive mechanism 2 is used to drive the first cover 1 to move along the height direction of the welding machine 4.

[0032] The adjusting mechanism 3 is used to adjust the position of the first cover 1 in a direction parallel to and / or perpendicular to the moving direction of the welding head 402. Optionally, the adjusting mechanism 3 can adjust the position of the first cover 1 in the height direction of the welding machine 4, and / or, the adjusting mechanism 3 can adjust the position of the first cover 1 in a direction perpendicular to the height direction of the welding machine 4.

[0033] In this embodiment, during the welding operation, as the welding head 402 descends, the driving mechanism 2 provides power to drive the first cover 1 to descend, allowing the first cover 1 to cover the outside of the welding head 402. During the welding process, the air inside the first cover 1 is drawn out by a suction device to remove impurities generated during welding, preventing impurities from falling onto the battery cell or drifting into the environment.

[0034] After welding is completed, the welding head 402 rises, and the first cover 1 can be driven to rise and reset by the drive mechanism 2 to avoid interference between the first cover 1 and the welding head 402.

[0035] After replacing different types of battery cells, the position of the first cover 1 can be adjusted by adjusting mechanism 3, so that the first cover 1 can both meet the requirement of covering the welding head 402 in the welding state and avoid or adapt to the battery cells.

[0036] In summary, by driving the first cover 1 to move along the direction of the welding head 402 through the drive mechanism 2, the cover can accurately cover the outside of the welding head 402 as it descends during welding, and return to its original position as the welding head 402 rises after welding. This not only prevents impurities from overflowing or falling onto the battery cell during welding, but also avoids interference with the movement of the welding head 402, ensuring stable dust removal throughout the welding process.

[0037] The adjustment mechanism 3 can adjust the position of the first cover 1 along the direction of movement parallel or perpendicular to the welding head 402. When replacing different sizes and types of battery cells, there is no need to replace the entire dust removal device. The cover can be adapted to the welding requirements of the new battery cell simply by adjustment, which improves the versatility and adaptability of the dust removal device and reduces the replacement cost and operation complexity of the welding equipment.

[0038] In some embodiments provided by this utility model, the adjustment mechanism 3 includes a first seat 301.

[0039] The first base 301 is adjustablely positioned on the machine body 401, and the adjustable direction of the first base 301 is intersecting or parallel to the moving direction of the welding head 402.

[0040] The drive mechanism 2 is located on the first base 301, and the drive end 201 of the drive mechanism 2 is connected to the first cover 1. For example, the drive mechanism 2 is a cylinder, hydraulic cylinder or electric cylinder, and the cylinder body of the drive mechanism 2 is directly or indirectly connected to the first base 301, and the drive end 201 of the drive mechanism 2 is directly or indirectly connected to the first cover 1.

[0041] In this embodiment, the adjustment mechanism 3 is configured as an adjustable first base 301, and the drive mechanism 2 is then installed on the base, forming a hierarchical structure in which the position of the first base 301 is adjusted and the action of the drive mechanism 2 is adjusted. By adjusting the installation position of the first base 301 on the body 401, the spatial layout of the dust collector can be changed as a whole, thereby adapting to different battery cell layouts. The adjustment logic is clear and the operation is simple.

[0042] Optionally, the body 401 is provided with a threaded hole, and the first seat 301 is provided with a through hole at a position opposite to the threaded hole. The dust removal device also includes a threaded fastener, which passes through the through hole and engages with the threaded hole to fix the first seat 301 to the body 401.

[0043] Furthermore, the through hole is an oblong hole, and the extension direction of the oblong hole is consistent with the position adjustment direction of the first seat 301. Alternatively, there are multiple threaded holes, which are arranged sequentially at intervals along the position adjustment direction of the first seat 301, and the threaded fastener can selectively engage with any one of the threaded holes.

[0044] It is understandable that, in order to ensure the fixing effect on the first seat 301, the number of threaded fasteners can be set to at least two, for example, the threaded fasteners are respectively inserted into different waist-shaped holes, or at least two threaded fasteners are inserted into at least one waist-shaped hole.

[0045] In this embodiment, if a waist-shaped hole design is adopted, the first seat 301 can achieve continuous position adjustment in the extension direction of the waist-shaped hole, which facilitates fine-tuning of the position of the first cover 1 according to the battery cell model and improves the alignment accuracy. If multiple spaced threaded holes are used, multi-level stepped adjustment can be achieved, which is simple in structure and reliable in positioning.

[0046] Of course, the scheme of having a through hole as a slotted hole and the scheme of having multiple threaded holes can be used in combination. That is, both the through hole is set to be slotted and the number of threaded holes is set to be multiple.

[0047] In this embodiment, the oblong hole allows the first seat 301 to be continuously fine-tuned within a certain range, while multiple threaded holes provide fixing points at different positions. The combination of the two allows for a wide range of position switching by selecting different threaded holes, and also allows for small-range fine adjustments when a single threaded hole is used in conjunction with the oblong hole, significantly expanding the overall adjustable range and adaptability flexibility, and better meeting the complex layout requirements of various battery cell models.

[0048] In some embodiments provided by this utility model, the adjustment mechanism 3 further includes a second seat 302.

[0049] The second seat 302 is adjustablely positioned on the first seat 301, and the adjustable direction of the second seat 302 intersects with the adjustable direction of the first seat 301, for example, the adjustable direction of the second seat 302 is perpendicular to the adjustable direction of the first seat 301.

[0050] The drive mechanism 2 is located on the second base 302. That is, the drive mechanism 2 is indirectly connected to the first base 301 through the second base 302. For example, the outer shell of the drive mechanism 2 is screwed to the second base 302, and the drive end 201 of the drive mechanism 2 is connected to the first cover 1.

[0051] In this embodiment, the adjustable directions of the first base 301 and the second base 302 intersect, so that the position of the first cover 1 can be adjusted in different directions, easily adapting to battery cells of different sizes and shapes, and avoiding adjustment limitations.

[0052] Optionally, the first seat 301 is provided with a threaded hole, and the second seat 302 is provided with a through hole at a position opposite to the threaded hole. The dust removal device also includes a threaded fastener, which passes through the through hole and engages with the threaded hole to fix the second seat 302 to the first seat 301.

[0053] Furthermore, the through hole is an oblong hole, and the extension direction of the oblong hole is consistent with the position adjustment direction of the second seat 302. Alternatively, there are multiple threaded holes, which are arranged sequentially at intervals along the position adjustment direction of the second seat 302, and the threaded fastener can selectively engage with any one of the threaded holes.

[0054] It is understandable that, in order to ensure the fixing effect on the second seat 302, the number of threaded fasteners can be set to at least two, for example, the threaded fasteners are respectively inserted into different waist-shaped holes, or at least two threaded fasteners are inserted into at least one waist-shaped hole.

[0055] In this embodiment, if a waist-shaped hole design is adopted, the second seat 302 can achieve continuous position adjustment in the extension direction of the waist-shaped hole, which facilitates fine-tuning of the position of the first cover according to the battery cell model and improves alignment accuracy. If multiple spaced threaded holes are used, multi-level stepped adjustment can be achieved, which is simple in structure and reliable in positioning.

[0056] Of course, the scheme of having a through hole as a slotted hole and the scheme of having multiple threaded holes can be used in combination. That is, both the through hole is set to be slotted and the number of threaded holes is set to be multiple.

[0057] In this embodiment, the oblong hole allows the second seat 302 to be continuously fine-tuned within a certain range, while multiple threaded holes provide fixing points at different positions. The combination of the two allows for a wide range of position switching by selecting different threaded holes, and also allows for small-range fine adjustments when a single threaded hole is used in conjunction with the oblong hole, significantly expanding the overall adjustable range and adaptability flexibility, and better meeting the complex layout requirements of various battery cell models.

[0058] Optionally, the first seat 301 is provided with a guide structure 3013, which extends along the position-adjustable direction of the second seat 302. The second seat 302 is slidably engaged with the guide structure 3013. For example, the guide structure 3013 can be a guide groove, and the second seat 302 is slidably disposed within the guide structure 3013. The bottom of the groove of the guide structure 3013 is provided with a threaded hole. Of course, the guide structure 3013 can also be a guide block, and the second seat 302 is provided with a sliding groove that slidably engages with the guide block.

[0059] In this embodiment, the guide structure 3013 provides a clear sliding path for the second seat 302, ensuring that it moves smoothly and without deviation during adjustment, avoiding uneven force on the drive mechanism 2 due to shaking or misalignment, and improving adjustment accuracy and operational reliability.

[0060] In addition, the second seat 302 can slide along the guide structure 3013 and select a suitable position. Then, it can be locked by threaded fasteners passing through its mounting hole and threaded hole, realizing the integration of "guiding, positioning and locking". No additional guide rails or brackets are required, the structure is simple and compact, and saves space.

[0061] In some embodiments provided by this utility model, the adjustment mechanism 3 further includes a third seat 303.

[0062] The third seat 303 is connected to the body 401, and the first seat 301 is adjustablely positioned on the third seat 303.

[0063] Specifically, the first seat 301 is indirectly connected to the body 401 via the third seat 303. Correspondingly, the third seat 303 is provided with a threaded hole, which corresponds to the through hole on the first seat 301. A threaded fastener passes through the first seat 301 and engages with the threaded hole of the third seat 303. There are multiple threaded holes, and / or the through hole is configured as a slotted hole. The specific position adjustment principle and advantages have been discussed above and will not be repeated here.

[0064] In this embodiment, the third base 303 serves as an interface module connected to the machine body 401. It can be customized according to the installation interface of different welding machines 4 without modifying the entire adjustment mechanism 3. Furthermore, combined with the design of a waist-shaped hole or multiple threaded holes, it can adapt to the installation hole positions of different machines without changing the main structure, improving the versatility of the device and the efficiency of equipment changeover.

[0065] In addition, by setting up a third seat 303, the adjustment mechanism 3 and the drive mechanism 2 can be disassembled and assembled as an independent unit, which facilitates quick replacement, maintenance or upgrade on site, and improves the maintainability and production continuity of the equipment.

[0066] Optionally, the third seat 303 is adjustablely disposed on the body 401, and the adjustable directions of the third seat 303, the first seat 301, and the second seat 302 intersect each other, for example, perpendicularly.

[0067] For ease of explanation, please refer to... Figure 6 As shown, the left-right direction of the welding machine 4 is defined as the first direction X, the front-back direction of the welding machine 4 is defined as the second direction Y, and the height direction of the welding machine 4 is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other.

[0068] For example, the first seat 301 is adjustablely positioned on the third seat 303 along the first direction X, the third seat 303 is adjustablely positioned on the body 401 along the second direction Y, and the second seat 302 is adjustablely positioned on the first seat 301 along the third direction Z.

[0069] In this embodiment, the third seat 303 is adjustable along the front and back, the first seat 301 is adjustable along the left and right, and the second seat 302 is adjustable along the up and down. The three are perpendicular to each other, so that the dust cover can be independently adjusted in three dimensions: front and back, left and right, and up and down. This allows for precise adaptation to the welding positions of different battery cells and improves the compatibility of the equipment with multiple product models.

[0070] In addition, the third seat 303 itself is adjustable, which can adapt to the differences in the installation reference of different welding machines 4, and improve the versatility and ease of installation of the device in different equipment.

[0071] Optionally, the body 401 is provided with a threaded hole, and the third seat 303 is provided with a through hole at a position opposite to the threaded hole. The dust removal device also includes a threaded fastener, which passes through the through hole and engages with the threaded hole to fix the third seat 303 to the body 401.

[0072] Furthermore, the through hole is an oblong hole, and the extension direction of the oblong hole is consistent with the position adjustment direction of the third seat 303, that is, the extension direction of the oblong hole intersects with or is parallel to the movement direction of the welding head 402. Alternatively, there are multiple threaded holes, which are arranged sequentially at intervals along the position adjustment direction of the third seat 303, and the threaded fastener can selectively engage with any one of the threaded holes.

[0073] It is understandable that, in order to ensure the fixing effect on the third seat 303, the number of threaded fasteners can be set to at least two, for example, the threaded fasteners are respectively inserted into different waist-shaped holes, or at least two threaded fasteners are inserted into at least one waist-shaped hole.

[0074] In this embodiment, if a waist-shaped hole design is adopted, the third seat 303 can achieve continuous position adjustment in the extension direction of the waist-shaped hole, which facilitates fine-tuning of the position of the first cover according to the battery cell model and improves alignment accuracy. If multiple spaced threaded holes are used, multi-level stepped adjustment can be achieved, which is simple in structure and reliable in positioning.

[0075] Of course, the scheme of having a through hole as a slotted hole and the scheme of having multiple threaded holes can be used in combination. That is, both the through hole is set to be slotted and the number of threaded holes is set to be multiple.

[0076] In this embodiment, the oblong hole allows the third seat 303 to be continuously fine-tuned within a certain range, while multiple threaded holes provide fixing points at different positions. The combination of the two allows for a wide range of position switching by selecting different threaded holes, and also allows for small-range fine adjustments when a single threaded hole is used in conjunction with the oblong hole, significantly expanding the overall adjustable range and adaptability flexibility, and better meeting the complex layout requirements of various battery cell models.

[0077] Optionally, the third seat 303 includes a connecting arm 3031 and a connecting rod 3032.

[0078] The device comprises two connecting arms 3031, which extend along a second direction and are spaced apart along a first direction. A connecting rod 3032 connects the two connecting arms 3031. For example, the connecting rod 3032 and the two connecting arms 3031 form a U-shaped structure.

[0079] Furthermore, the two connecting arms 3031 are connected to the top surface of the body 401. For example, the two connecting arms 3031 are provided with through holes, and the top surface of the body 401 is provided with threaded holes. The first seat 301 is connected to the connecting rod 3032, or in other words, the first seat 301 is adjustablely positioned on the connecting rod 3032.

[0080] In this embodiment, the two spaced connecting arms 3031 and the connecting rod 3032 disposed therebetween form a U-shaped frame, which is firmly connected and has strong resistance to deformation. The connecting arms 3031 are fixed to the top surface of the body 401 at two points, which effectively improves the support stability, ensures that the subsequent adjustment structure does not shake during operation, and guarantees the positioning accuracy of the dust collector hood.

[0081] refer to Figure 3 As shown, optionally, the first base 301 includes a first adjusting plate 3011 and a first connecting plate 3012.

[0082] The first adjusting plate 3011 and the first connecting plate 3012 are connected and perpendicular to each other, for example, they are set as an integral structure. The first adjusting plate 3011 is adjustablely disposed on the third seat 303, for example, the first adjusting plate 3011 is adjustablely overlapped on the top surface of the connecting rod 3032.

[0083] Furthermore, the first connecting plate 3012 extends downward from the end opposite to the first adjusting plate 3011. The first connecting plate 3012 is connected to the second seat 302. For example, the first connecting plate 3012 is provided with a guide structure 3013 for guiding the second seat 302. The guide structure 3013 can be disposed on the surface of the first connecting plate 3012 opposite to the body 401.

[0084] In this embodiment, the first connecting plate 3012 extends downward and is provided with a guide structure 3013, which directly provides vertical sliding guidance for the second seat 302. The structure is compact, the guide path is long, the movement is smooth, and the off-center load is avoided, ensuring that the dust cover is lifted and lowered vertically without deviation.

[0085] refer to Figure 3 As shown, optionally, the second seat 302 includes a second adjusting plate 3021 and a second connecting plate 3022.

[0086] The second adjusting plate 3021 and the second connecting plate 3022 are connected and perpendicular to each other, for example, they are set as an integral structure. The second adjusting plate 3021 is adjustablely disposed on the first base 301, for example, the second adjusting plate 3021 is slidably engaged with the guide structure 3013 of the first base 301.

[0087] The second connecting plate 3022 is connected to the bottom end of the second adjusting plate 3021 and extends away from the body 401. The second connecting plate 3022 is connected to the drive mechanism 2, for example, the drive mechanism 2 is screwed to the bottom surface of the second connecting plate 3022.

[0088] In this embodiment, the second adjusting plate 3021 slides up and down along the guide structure 3013 of the first base 301. With the help of the locking structure, the height position of the drive mechanism 2 can be precisely adjusted to ensure that the first cover 1 and the welding head 402 maintain the best alignment under different working conditions, thereby improving the dust removal effect and adaptability.

[0089] The second connecting plate 3022 extends horizontally forward, and the drive mechanism 2 is installed on its bottom surface, so that the entire drive and dust cover assembly moves forward and away from the body 401 and the connecting structure, effectively avoiding the welding head 402, the battery cell and surrounding components, reducing spatial conflicts and facilitating equipment layout.

[0090] In some embodiments provided by this utility model, the dust removal device further includes a first adjusting seat 5.

[0091] The first adjusting seat 5 is connected to the driving end 201 of the driving mechanism 2. For example, the first adjusting seat 5 is screwed to the driving end 201 of the driving mechanism 2.

[0092] Furthermore, the first cover 1 is adjustablely positioned on the first adjusting seat 5, and the adjustable direction of the first cover 1 intersects with the adjustable direction of the first seat 301. For example, the adjustable directions of the first cover 1, the first seat 301, and the second seat 302 are perpendicular to each other. For example, the first cover 1 is adjustablely positioned on the first adjusting seat 5 along the second direction Y.

[0093] In this embodiment, the adjustment mechanism 3 is responsible for the overall positioning of the first cover 1 and the drive mechanism 2, and the first adjustment seat 5 is responsible for the fine adjustment of the first cover 1. The functions of the first adjustment seat 5 and the adjustment mechanism 3 are separated, which avoids repeated adjustments to the main structure, simplifies the debugging process, and improves the efficiency of model changeover.

[0094] Optionally, the first cover 1 is provided with a threaded hole, and the first adjusting seat 5 is provided with a through hole at a position opposite to the threaded hole. The dust removal device also includes a threaded fastener, which passes through the through hole and engages with the threaded hole to fix the first adjusting seat 5 to the first cover 1.

[0095] Furthermore, the through hole is an oblong hole, and the extension direction of the oblong hole is consistent with the position adjustment direction of the first adjusting seat 5. Alternatively, there are multiple threaded holes, which are arranged sequentially at intervals along the position adjustment direction of the first adjusting seat 5, and the threaded fastener can selectively engage with any one of the threaded holes.

[0096] Of course, the scheme of having a through hole as a slotted hole and the scheme of having multiple threaded holes can be used in combination. That is, both the through hole is set to be slotted and the number of threaded holes is set to be multiple.

[0097] Optionally, the third adjustment seat is a plate, which is connected to the drive end 201 of the drive mechanism 2, and the first cover 1 is connected to the bottom surface of the plate.

[0098] In some embodiments provided by this utility model, the dust removal device further includes a second cover 6.

[0099] The second cover 6 is fitted outside the bottom mold 403 of the welding machine 4 and has an opening facing the first cover 1. The first cover 1 has a mating interface opposite to the opening.

[0100] The drive mechanism 2 can drive the first cover 1 to dock with the second cover 6, so that the two form a cavity for accommodating the welding head 402 and the bottom mold 403. At least one of the first cover 1 and the second cover 6 is provided with a feed inlet 601 and at least one of them is provided with a suction port 602. The feed inlet 601 allows the power supply core to enter into the cavity, and the suction port 602 is used to connect to a suction device.

[0101] For example, refer to Figure 6 The illustration shows an example where the second cover 6 has a suction port 602, in which case the first cover 1 is connected to the suction device via the second cover 6. Of course, in other embodiments, the first cover 1 may also be provided with a suction port 602. Figure 6 In the middle, both the first cover 1 and the second cover 6 are provided with a feed port 601, which is used to avoid the battery cell so that the battery cell can enter the cavity.

[0102] In this embodiment, the first cover 1 descends and docks with the second cover 6, completely enclosing the welding head 402 and the bottom mold 403 in the cavity. The dust generated during welding is confined in the sealed space and efficiently discharged through the suction port 602, reducing dust overflow, effectively preventing contamination of the battery cell, and improving battery safety and yield.

[0103] In addition, the first cover 1 rises and falls with the welding head 402 to achieve dynamic following, while the second cover 6 is fixed on the outside of the bottom mold 403 for stable positioning. The docking of the two not only ensures dust removal throughout the welding process, but also avoids interference of the fixed cover with the loading and unloading of the battery cells, thus taking into account both functional and process requirements.

[0104] In some embodiments of this utility model, the second cover 6 is adjustablely disposed on the machine body 401, and the adjustable direction of the second cover 6 intersects or is parallel to the moving direction of the welding head 402. For example, the second cover 6 is adjustablely disposed on the base of the machine body 401 along the first direction X, that is, the adjustable directions of the second cover 6 and the first base 301 are the same.

[0105] In this embodiment, the first cover 1 is adjustable, and the second cover 6 is also adjustable. When the two are connected, the position can be flexibly calibrated at the bottom to ensure precise alignment with the welding head 402 and the bottom mold 403, avoiding eccentricity of the cover due to assembly errors or changes in the battery cell model, and improving the sealing performance and dust removal reliability of the enclosed cavity.

[0106] Furthermore, the position of the bottom mold 403 may change when changing to different types of battery cells. The second cover 6 is adjustable and can be adjusted in the first direction X to accommodate different bottom molds 403 or battery cell layouts, ensuring that the feed port 601 is aligned with the battery cell channel, while also ensuring smooth docking with the first cover 1, and adapting to more product specifications.

[0107] Optionally, the dust removal device further includes a second adjusting seat 7, which is connected to the second cover 6, for example, by screwing. The base has a threaded hole, and the second adjusting seat 7 has a through hole at a position opposite to the threaded hole. The dust removal device also includes a threaded fastener, which passes through the through hole and engages with the threaded hole to fix the second adjusting seat 7 to the base.

[0108] Furthermore, the through hole is an oblong hole, and the extension direction of the oblong hole is consistent with the position adjustment direction of the second cover 6. Alternatively, there are multiple threaded holes, which are arranged sequentially at intervals along the position adjustment direction of the second cover 6, and the threaded fastener can selectively engage with any one of the threaded holes.

[0109] Of course, the scheme of having a through hole as a slotted hole and the scheme of having multiple threaded holes can be used in combination. That is, both the through hole is set to be slotted and the number of threaded holes is set to be multiple.

[0110] Optionally, the dust removal device also includes a filter element disposed at the suction port 602. In this embodiment, the filter element disposed at the suction port 602 can prevent welding dust and particulate matter from entering the suction device, avoiding blockage of pipelines or pump body and reducing equipment failure.

[0111] The foregoing has described a scheme for adjusting the position of the first cover 1 using the first seat 301, the second seat 302, or the third seat 303. It is understood that this scheme is not limited to adjusting the position of the first cover 1 using seats. For example, in some embodiments not shown in this invention, the adjusting mechanism 3 is configured as a linear module. For instance, the linear module can be a biaxial or triaxial linear module, thereby enabling automated and digital adjustment through the linear module, quickly responding to the positional requirements of different battery cells.

[0112] This utility model also provides a welding device.

[0113] The welding equipment includes an ultrasonic welding machine 4 and the dust removal device described above.

[0114] It should be noted that the welding equipment includes a dust removal device, and therefore also includes all the advantages of the dust removal device mentioned above, so it will not be elaborated further.

[0115] This utility model also provides a battery cell production line.

[0116] The battery cell production line includes the dust removal device as described above or the welding equipment as described above.

[0117] It should be noted that the battery cell production line includes a dust removal device, and therefore also includes all the advantages of the dust removal device mentioned above, so it will not be elaborated further.

[0118] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
