[0003] The present application provides a dust removal device and a battery manufacturing system. The technical solution provided in the present application can effectively improve the dust removal efficiency and reduce the impact of dust on the environment.

[0004] In a first aspect, the present application provides a dust removal device, which includes a dust removal bin, an air blowing mechanism, and a dust collecting mechanism. The dust removal bin has a storage chamber inside, and the dust removal bin is provided with a bin door and a dust exhaust port. The bin door is used for the dust-removed parts to enter or leave the storage chamber, and the dust exhaust port is connected to the storage chamber. The air blowing mechanism is arranged in the storage chamber, and is used to provide airflow to the dust-removed parts in the storage chamber to blow off the dust on the dust-removed parts. The dust collecting mechanism is connected to the dust exhaust port, and is used to provide negative pressure to the storage chamber and collect dust.

[0005] In the above scheme, the parts to be dusted (such as high-efficiency filter elements) are placed in the dust removal bin. With the airflow provided by the blowing mechanism and the negative pressure provided by the dust collecting mechanism, on the one hand, the dust on the parts to be dusted can be effectively removed from the parts to be dusted, thereby efficiently cleaning and collecting the dust. On the other hand, because the parts to be dusted are removed in a closed containing chamber, the risk of dust drifting to the external environment is low, effectively reducing the impact of dust on the environment and workers.

[0006] According to some embodiments of the present application, the blowing mechanism includes a wind knife and a driving assembly. The wind knife is used to provide airflow to the part to be dusted. The driving assembly is arranged in the dust removal bin and connected to the wind knife. The driving assembly is used to drive the wind knife to swing.

[0007] In the above scheme, by setting a driving component, the wind knife is allowed to swing in the accommodating chamber, thereby providing airflows at different angles to the dust-removed parts, effectively blowing off the dust on the dust-removed parts, thereby achieving high dust removal efficiency.

[0008] According to some embodiments of the present application, the driving assembly includes a connecting portion, a rotating shaft, and a driving portion. The connecting portion is connected to the dust removal bin, the rotating shaft is rotatably connected to the connecting portion, the wind knife is connected to the rotating shaft, and the driving portion is transmission-connected to the rotating shaft and is used to drive the rotating shaft to drive the wind knife to swing.

[0009] In the above scheme, by setting a connecting part and a rotating shaft, the wind knife can swing in the accommodating chamber, and provide airflows at different angles to the dust-removing parts under the drive of the driving part, effectively blowing off the dust on the dust-removing parts, so that the dust removal efficiency is high.

[0010] According to some embodiments of the present application, the driving part includes a gear, a rack and a driving member, the gear is sleeved on the rotating shaft, the rack is meshed with the gear, the driving member is connected to the rack and drives the rack to reciprocate along a first direction, and the first direction is perpendicular to the axial direction of the rotating shaft.

[0011] In the above scheme, the rack is driven to make a linear reciprocating motion along the first direction by the driving member, so that the gear can rotate forward or reverse at a certain frequency, thereby driving the wind knife to swing back and forth through the rotating shaft, providing airflows at different angles to the dust-removing parts at a certain frequency, effectively blowing off the dust on the dust-removing parts, and achieving high dust removal efficiency.

[0012] According to some embodiments of the present application, the driving unit further includes a linear guide rail, which is connected to the dust removal bin, and the linear guide rail is connected to the rack and is used to guide the rack to move along the first direction.

[0013] In the above scheme, by setting a linear guide rail, the rack can be constrained and guided, so that the rack can stably move back and forth along the first direction under the drive of the driving member, so that the wind knife swings stably, and provides airflows at different angles to the dust-removed parts at a certain frequency with high reliability, effectively blowing off the dust on the dust-removed parts, thereby improving the dust removal efficiency.

[0014] According to some embodiments of the present application, there are multiple rotating shafts, and the multiple rotating shafts are arranged at intervals along the first direction. Each rotating shaft is provided with at least one wind knife, and the first direction is perpendicular to the axial direction of the rotating shaft.

[0015] In the above scheme, by setting up multiple rotating shafts and multiple wind knives, the multiple wind knives can swing back and forth simultaneously under the drive of the driving unit, thereby providing a large amount of airflow at different angles to the dust-removing parts, effectively blowing off the dust on the dust-removing parts, and improving the dust removal efficiency.

[0016] According to some embodiments of the present application, the dust collection mechanism includes a dust bucket and a negative pressure fan. The dust bucket has a collection chamber inside. The dust bucket is connected to the dust exhaust port to connect the collection chamber and the accommodating chamber. The negative pressure fan is connected to the dust bucket for providing negative pressure to the collection chamber.

[0017] In the above scheme, by setting up a dust collecting bucket and a negative pressure fan, the dust in the containing chamber can be collected in the dust collecting bucket under the negative pressure provided by the negative pressure fan, reducing the risk of dust drifting to the external environment and effectively reducing the impact of dust on the environment and workers.

[0018] According to some embodiments of the present application, the dust removal bin includes a top wall, a bottom wall and a peripheral wall, the top wall and the bottom wall are arranged opposite to each other along a second direction, the peripheral wall is arranged between the top wall and the bottom wall, the bin door is arranged on the peripheral wall, and the dust exhaust port is arranged on the bottom wall, and the second direction is parallel to the direction of gravity.

[0019] In the above scheme, by arranging the bin door on the peripheral wall, the parts to be dusted can be placed in the accommodating chamber from the side, thereby reducing the difficulty of transporting the parts to be dusted; at the same time, by arranging the dust exhaust port on the bottom wall, on the one hand, the dust can be efficiently separated from the parts to be dusted under the action of gravity and wind, and the dust removal efficiency is high; on the other hand, the blown dust can be effectively collected by the dust collecting mechanism under the action of its gravity, and the dust collection efficiency is high.

[0020] According to some embodiments of the present application, the dust removal bin is provided with a support portion, which is located in the accommodating cavity and is used to support the parts to be dusted; along the second direction, the blowing mechanism and the dust exhaust port are respectively located on two opposite sides of the support portion.

[0021] In the above scheme, by arranging the blowing mechanism and the dust exhaust port on opposite sides of the support part, the airflow provided by the blowing mechanism blows the dust on the surface of the dust removal part to the dust exhaust port, which is beneficial for the dust collecting component to effectively collect the dust, reduces the risk of dust adhering to the filter element again or splashing, and improves the dust removal efficiency.

[0022] According to some embodiments of the present application, the bottom wall includes a flange and a funnel. The flange is arranged around the edge of the funnel and connected to the peripheral wall. Along the second direction, the funnel protrudes in a direction away from the top wall, and the end of the funnel away from the top wall forms a dust exhaust port.

[0023] In the above scheme, by setting a funnel, a space can be formed below the part to be removed when it is placed in the accommodating chamber, so that the dust blown off by the airflow can smoothly enter the funnel, so that the dust collecting component can effectively collect the dust, reduce the risk of dust adhering to the filter element again or splashing, and improve the dust removal efficiency and the efficiency of dust collection.

[0024] According to some embodiments of the present application, along the second direction, the flange has a first surface facing the top wall, and the first surface is at least a part of the support portion.

[0025] In the above scheme, the first surface of the flange can be used to effectively support the dust-removed piece, and under the action of the airflow provided by the blowing mechanism, the dust on the surface of the dust-removed piece can be blown into the funnel below the dust-removed piece.

[0026] According to some embodiments of the present application, the first surface has a first edge connected to the edge of the funnel. The first surface is provided with a restraining member, the restraining member is spaced apart from the first edge, and the restraining member is used to restrain the dust-removed object.

[0027] In the above scheme, the position of the dust-removing piece can be limited by setting a constraint part, so that the dust-removing piece is stably located on the first surface in the airflow provided by the blowing mechanism, thereby reducing the risk of the dust-removing piece being offset due to the impact of the airflow and causing the dust to be unable to be effectively blown off, thereby improving the dust removal efficiency.

[0028] In a second aspect, the present application also provides a battery manufacturing system, comprising the dust removal device of any one of the first aspects.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0040] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0041] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists, A and B exist at the same time, and B exists. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0043] In the present application, the battery may include a lithium-ion battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery or a magnesium-ion battery, etc., which is not limited in the embodiments of the present application. The battery may be cylindrical, flat, rectangular or other shapes, etc., which is not limited in the embodiments of the present application.

[0044] The battery will generate dust during the manufacturing process, such as the collector dust generated in the tab cutting process (such as cutting the current collector without active material layer to obtain the tab of the desired shape or position), welding slag dust generated in the welding process (such as welding the tab and electrode output structure, welding the battery shell), etc. In order to effectively remove dust and improve the quality of the battery, dust removal equipment is often used for dust removal. In order to reduce the impact of dust on the environment, the dust removal equipment is equipped with a filter element, which can absorb dust to meet the emission requirements.

[0045] After the dust removal equipment has been working for a period of time, the performance of the dust removal equipment will be reduced due to excessive dust accumulation in the filter element, and the dust generated during the battery manufacturing process cannot be effectively processed, so the filter element needs to be dusted. The current dust removal method for the filter element is that the operator takes the filter element out of the dust removal equipment and uses a high-pressure fan to provide airflow to the filter element to blow out the dust. However, the current dust removal of the filter element is often carried out in an external environment and manual dust removal is used, so there are problems of low dust removal efficiency and poor dust removal effect, as well as dust pollution of the environment and safety impacts on workers.

[0046] In view of this, some embodiments of the present application provide a dust removal device, which includes a dust removal bin, an air blowing mechanism, and a dust collecting mechanism. The dust removal bin has a accommodating chamber inside, and the dust removal bin is provided with a bin door and a dust discharge port. The bin door allows the filter element to enter or leave the accommodating chamber, and the dust discharge port is connected to the accommodating chamber. The air blowing mechanism is arranged in the accommodating chamber, and is used to provide airflow to the filter element in the accommodating chamber to blow off the dust on the filter element. The dust collecting mechanism is connected to the dust discharge port, and is used to provide negative pressure to the accommodating chamber and collect dust.

[0047] In the above scheme, the filter element is placed in the dust removal bin, and with the airflow provided by the blowing mechanism and the negative pressure provided by the dust collecting mechanism, on the one hand, the dust on the filter element can efficiently leave the filter element, thereby improving the dust removal efficiency and effect of the filter element, so that the clean filter element can effectively adsorb dust during the battery manufacturing process; on the other hand, because the dust removal parts are removed in a closed containing chamber, the risk of dust drifting to the external environment is low, effectively reducing the impact of dust on the environment and workers.

[0048] The dust removal device disclosed in the embodiment of the present application includes but is not limited to dust removal of filter elements used in the battery manufacturing process, and can also be used to remove dust from filter elements used in other production lines, or can also be used to remove dust from other parts to be dusted, such as air filters on vehicles. The dust removal device disclosed in the embodiment of the present application can be applied to a battery manufacturing system, that is, the present application also discloses a battery manufacturing system including the dust removal device.

[0049] In some embodiments of the present application, the dust removal device 100 is described by taking a filter element as an example of a dust removal part.

[0050] Some embodiments of the present application provide a dust removal device, see Figure 1-Figure 3 , Figure 1 This is a three-dimensional diagram of a dust removal device in some embodiments of the present application. Figure 2 This is a three-dimensional diagram of a dust removal device and a dust removal object in some embodiments of the present application. Figure 3 This is a three-dimensional diagram of a dust removal device with partially hidden structures in some embodiments of the present application.

[0051] The dust removal device 100 includes a dust removal bin 10, an air blowing mechanism 20, and a dust collecting mechanism 30. The dust removal bin 10 has a receiving chamber 13 inside, and the dust removal bin 10 is provided with a bin door 11 and a dust discharge port 12. The bin door 11 allows the dust-removed parts 200 to enter or leave the receiving chamber 13, and the dust discharge port 12 is connected to the receiving chamber 13. The air blowing mechanism 20 is arranged in the receiving chamber 13, and is used to provide airflow to the dust-removed parts 200 in the receiving chamber 13, so as to blow off the dust on the dust-removed parts 200. The dust collecting mechanism 30 is connected to the dust discharge port 12, and is used to provide negative pressure to the receiving chamber 13 and collect dust.

[0052] The dust removal bin 10 provides a accommodating chamber 13 for the dust removal parts 200, so that the dust removal parts 200 can be dusted in a closed space. In some embodiments, the dust removal bin 10 may include a frame-shaped frame 19 and a wall portion surrounding the frame-shaped frame 19, and the wall portion may be a skin. The frame-shaped frame 19 includes a plurality of cross bars and vertical bars, and the cross bars and vertical bars are connected to each other to form a frame shape. The wall portion may be made of a metal material or a non-metallic material, and the wall portion may be connected to the frame-shaped frame 19 by screw connection, bonding or other methods to enclose at least part of the accommodating chamber 13. The bin door 11 is a structure arranged in the dust removal bin 10, and the bin door 11 is a structural member on the dust removal bin 10 that can be opened and closed. By opening the bin door 11, the dust removal parts 200 can enter or leave the accommodating chamber 13. The dust discharge port 12 is arranged in the dust removal bin 10 and communicates with the accommodating chamber 13 . The dust discharge port 12 is connected to the dust collecting mechanism 30 . The dust collecting mechanism 30 can provide negative pressure to the accommodating chamber 13 so that the dust in the accommodating chamber 13 enters the dust collecting mechanism 30 through the dust discharge port 12 .

[0053] For example, see Figure 1-Figure 3 The dust removal bin 10 may include a frame-shaped frame 19 and a wall portion surrounding the frame-shaped frame 19. The frame-shaped frame 19 is a square frame, and the wall portion includes a top wall 14, a side wall and a bottom wall 15. The number of side walls may be multiple, wherein multiple side walls are surrounded by the side of the frame-shaped frame 19, the top wall 14 is arranged at the top of the frame-shaped frame 19, and together with the frame-shaped frame 19, a first opening with an opening facing the side and a second opening with an opening facing downward are formed. The bottom wall 15 is connected to the frame-shaped frame 19 and closes the second opening, and the bottom wall 15 forms a dust discharge port 12. The bin door 11 is hinged to the frame-shaped frame 19 for closing the first opening. The bin door 11 can be flipped relative to the frame-shaped frame 19 to open the first opening, so that the dust removal part 200 to be removed can enter the accommodating chamber 13. The side wall adjacent to the bin door 11 may be provided with a lock 110, and the lock 110 is used to lock the bin door 11 so that the bin door 11 is in a state of closing the first opening. In some embodiments, the locking member 110 may be a hinge lock or other locking member capable of fixing the door 11 to the dust removal bin 10. In some embodiments, the bottom wall 15 may include a funnel 151, and the constricted opening of the funnel 151 is the dust discharge port 12.

[0054] The blowing mechanism 20 is arranged inside the accommodating chamber 13. In some embodiments, the blowing mechanism 20 can be connected to the frame-shaped frame 19. The blowing mechanism 20 is used to provide airflow to the dust-removed part 200 in the accommodating chamber 13. The airflow flows at a high speed and can blow off the dust attached to the surface of the dust-removed part 200. In some embodiments, the dust-removed part 200 is a filter element, which includes a core body and a frame surrounding the core body. The frame is supported by the bottom wall 15 of the frame-shaped frame 19. Below the core body is a funnel 151. The blowing mechanism 20 provides airflow to the core body, and the airflow acts on the core body to blow the dust attached to the core body toward the funnel 151, so that it is collected by the dust collecting mechanism 30. In some embodiments, the blowing mechanism 20 includes a wind knife 21, which is connected to a high-pressure air source (such as a high-pressure blower) through a pipeline, and the air outlet of the wind knife 21 is arranged toward the dust-removed part 200.

[0055] The dust collecting mechanism 30 is connected to the dust discharge port 12, thereby communicating with the accommodating chamber 13. The dust collecting mechanism 30 can provide negative pressure, and the dust in the accommodating chamber 13 enters the dust collecting mechanism 30 under the action of the negative pressure. Exemplarily, the dust collecting mechanism 30 includes a dust collecting bucket 31 and a negative pressure fan 32, the dust collecting bucket 31 has a collection chamber inside, and the dust collecting bucket 31 is connected to the constriction of the funnel 151 through a pipeline. The negative pressure fan 32 is connected to the dust collecting bucket 31 to provide negative pressure to the collection chamber. In some embodiments, the dust collecting bucket 31 and the negative pressure fan 32 are provided with a filter element, which is used to filter dust so that the dust content of the gas discharged by the negative pressure fan 32 is small. In other embodiments, the dust collecting mechanism 30 may include a dust collecting bag, and the dust collecting bag is used to collect dust in the accommodating chamber 13.

[0056] In the above scheme, the dust-removing part 200 is placed in the dust removal bin 10, and the airflow provided by the blowing mechanism 20 and the negative pressure provided by the dust collecting mechanism 30 are used. On the one hand, the dust on the dust-removing part 200 can be effectively removed from the dust-removing part 200, and the dust can be efficiently cleaned and collected. On the other hand, since the dust is removed in the closed accommodating chamber 13, the risk of dust drifting to the external environment is low, which effectively reduces the impact of dust on the environment and the staff. In some embodiments, the staff may include staff in the battery manufacturing workshop or factory.

[0057] According to some embodiments of this application, see Figure 2 and Figure 3 The blowing mechanism 20 includes a wind knife 21 and a driving assembly 22. The wind knife 21 is used to provide airflow to the dust removal part 200. The driving assembly 22 is arranged in the dust removal bin 10 and connected to the wind knife 21. The driving assembly 22 is used to drive the wind knife 21 to swing.

[0058] In some embodiments, the wind knife 21 may refer to a component used in industry to blow out high-speed thin-sheet airflow. The wind knife 21 may be driven by a vortex blower or a high-pressure centrifugal blower.

[0059] In some embodiments, the driving assembly 22 is disposed in the dust removal bin 10 and connected to the wind knife 21, and is used to drive the wind knife 21 to swing back and forth, so as to change the air outlet of the wind knife 21, so that the wind knife 21 acts on the dust removal part 200 at different angles. Exemplarily, the dust removal part 200 is a filter element, and the wind knife 21 is located above the filter element. The wind knife 21 swings back and forth under the drive of the driving assembly 22, and the effective area of ​​the airflow blown out by it can cover the surface of the filter element, so as to remove dust from the core in all directions.

[0060] In the above scheme, by setting the driving component 22, the wind knife 21 swings in the accommodating chamber 13, so as to provide airflows at different angles to the dust-removing part 200, increase the dust removal area, and effectively blow off the dust on the dust-removing part 200, so as to improve the dust removal efficiency.

[0061] In other embodiments, the wind knife 21 can be fixed in the dust removal bin 10 to provide airflow to the dust removal part 200 at a fixed angle.

[0062] In other embodiments, the blowing mechanism 20 may further include an air nozzle, which is connected to an air source via a pipeline, and an air outlet of the air nozzle is arranged toward the part to be dusted 200 .

[0063] According to some embodiments of this application, see Figure 3-Figure 5 , Figure 4 for Figure 3 The enlarged view of point A in the middle. Figure 5 It is a top view of the local structure of the dust removal device 100 in some embodiments of the present application.

In some embodiments, the rotating shaft 221 is driven to rotate back and forth by the driving portion 222, so that the wind knife 21 can swing back and forth. Along the second direction z, the dust removal piece 200 can be on one side of the wind knife 21. In some embodiments, the second direction z can be parallel to the direction of gravity.

[0066] In some embodiments, the number of the connecting parts 220 can be multiple, for example, the number of the connecting parts 220 is two, and the two connecting parts 220 are arranged at intervals along the third direction y to jointly support the rotating shaft 221.

[0067] In some embodiments, the connecting portion 220 may be eliminated, and the rotating shaft 221 may be directly fixed to the wall of the dust removal bin 10 .

[0068] In some embodiments, the driving unit 222 may be a driving structure capable of driving the rotating shaft 221 to reciprocate.

Along the third direction y, the rack 2221 is located on one side of the two connecting parts 220. Along the third direction y, one end of the rotating shaft 221 is inserted into the support part 17 farthest from the rack 2221, and a bearing may be provided between the two. The other end of the rotating shaft 221 passes through the connecting part 220 adjacent to the rack 2221, and a bearing may be provided between the two. The end of the rotating shaft 221 passing through the connecting part 220 is provided with a gear 2220, and the gear 2220 may be fixedly connected to the rotating shaft 221 and meshed with the rack 2221.

[0072] The driving member 2222 is a driving structure capable of outputting linear motion. Under the drive of the driving member 2222, the rack 2221 can reciprocate along the first direction x, thereby driving the gear 2220 and the rotating shaft 221 to reciprocate, thereby causing the wind knife 21 to swing back and forth. In some embodiments, the driving member 2222 can be a linear push rod, a cylinder, or other driving structure capable of outputting linear motion.

[0073] In the above scheme, the driving member 2222 drives the rack 2221 to make a linear reciprocating motion along the first direction x, so that the gear 2220 can rotate forward or reverse at a certain frequency, thereby driving the wind knife 21 to swing back and forth through the rotating shaft 221, providing airflows at different angles to the dust removal part 200 at a certain frequency, thereby increasing the dust removal area, effectively blowing off the dust on the dust removal part 200, and achieving high dust removal efficiency.

[0074] According to some embodiments of this application, see Figure 4 The driving part 222 further includes a linear guide rail 2223, which is connected to the dust removal bin 10, and the linear guide rail 2223 is connected to the rack 2221 and is used to guide the rack 2221 to move along the first direction x.

[0075] In some embodiments, the linear guide 2223 can be disposed on the frame-shaped frame 19, and the slider of the linear guide 2223 can be connected to the rack 2221, so as to support the rack 2221, improve the reliability of the meshing between the rack 2221 and the gear 2220, and guide the rack 2221 to stably reciprocate along the first direction x. In some embodiments, the linear guide 2223 includes a track and a plurality of sliders disposed on the track, the track extends along the first direction x, the slider slides relative to the track along the first direction x, and the plurality of sliders are spaced apart along the first direction x and are all connected to the rack 2221.

[0076] In the above scheme, by setting a linear guide rail 2223, the rack 2221 can be constrained and guided, so that the rack 2221 can stably move back and forth along the first direction x under the drive of the driving member 2222, so that the wind knife 21 swings stably, and provides airflows at different angles to the dust-removed part 200 at a certain frequency with high reliability, effectively blowing off the dust on the dust-removed part 200, so that the dust removal efficiency is high.

[0077] According to some embodiments of this application, see Figure 5 There are multiple rotating shafts 221, and the multiple rotating shafts 221 are arranged at intervals along the first direction x. Each rotating shaft 221 is provided with at least one wind knife 21, and the first direction x is perpendicular to the axial direction of the rotating shaft 221.

[0078] In some embodiments, the number of the rotating shafts 221 may be multiple, for example, two, three, four or more. Figure 5 , three rotating shafts 221 are arranged on the connecting portion 220 at intervals along the first direction x.

[0079] In some embodiments, each rotating shaft 221 may be provided with at least one wind knife 21, for example, each rotating shaft 221 may be provided with one, two or more wind knives 21. Figure 5 Each rotating shaft 221 is provided with a wind knife 21 .

[0080] In some embodiments, each wind knife 21 is equipped with a pipeline, and the wind knife 21 is connected to the air source through the corresponding pipeline. In other embodiments, all the wind knives 21 are connected to the air source through a collecting pipeline.

[0081] In the above scheme, by setting up multiple rotating shafts 221 and multiple wind knives 21, multiple wind knives 21 can be driven by the driving part 222 to swing back and forth simultaneously, thereby providing a large amount of airflow at different angles to the dust-removing part 200, effectively blowing off the dust on the dust-removing part 200, and achieving high dust removal efficiency.

[0082] According to some embodiments of this application, see Figure 1 and Figure 2 The dust collecting mechanism 30 includes a dust collecting bucket 31 and a negative pressure fan 32. The dust collecting bucket 31 has a collecting chamber inside. The dust collecting bucket 31 is connected to the dust exhaust port 12 to connect the collecting chamber and the accommodating chamber 13. The negative pressure fan 32 is connected to the dust collecting bucket 31 to provide negative pressure to the collecting chamber.

[0083] The dust collecting barrel 31 is barrel-shaped and has an inlet and an outlet communicating with the collecting chamber. The inlet is connected to the dust exhaust port 12 through a pipeline, and the outlet is connected to the negative pressure fan 32 .

[0084] In some embodiments, the dust bucket 31 can be detachably connected to the dust exhaust port 12 (for example, the dust bucket 31 is connected to the dust exhaust port 12 through a clamp and a pipe). By removing the dust bucket 31 and opening the lid of the dust bucket 31, the dust in the collection chamber can be easily cleaned.

[0085] In the above scheme, by providing a dust collecting bucket 31 and a negative pressure fan 32, the dust in the accommodating chamber 13 can be collected in the dust collecting bucket 31 under the negative pressure provided by the negative pressure fan 32, thereby reducing the risk of dust drifting to the external environment and effectively reducing the impact of dust on the environment and workers.

[0086] According to some embodiments of this application, see Figure 1 and Figure 2 The dust removal bin 10 includes a top wall 14, a bottom wall 15 and a peripheral wall 16. The top wall 14 and the bottom wall 15 are arranged opposite to each other along a second direction z. The peripheral wall 16 is arranged between the top wall 14 and the bottom wall 15. The bin door 11 is arranged on the peripheral wall 16. The dust exhaust port 12 is arranged on the bottom wall 15. The second direction z is parallel to the direction of gravity.

[0087] In some embodiments, the accommodating chamber 13 can be surrounded by a top wall 14, a bottom wall 15, and a peripheral wall 16. The top wall 14 and the bottom wall 15 are arranged opposite to each other in the direction of gravity, and the peripheral wall 16 is located between the top wall 14 and the bottom wall 15. The peripheral wall 16 includes a plurality of side walls. Exemplarily, the accommodating chamber 13 is a square chamber, and the peripheral wall 16 includes four side walls, which are connected end to end and surrounded by the edge of the top wall 14 and the edge of the bottom wall 15. In some embodiments, one of the side walls is formed with a first opening, and the compartment door 11 is arranged corresponding to the first opening for closing the first opening.

[0088] In some embodiments, the top wall 14 may be provided with a visual window 140 , through which an operator can understand the status inside the accommodating cavity 13 .

[0089] In some embodiments, the pipe of the air knife 21 for connecting to the air source can pass through the top wall or the peripheral wall to connect to the air source. The pipe and the top wall or the peripheral wall can be sealed, for example, by providing a sealing ring.

[0090] In the above scheme, by setting the bin door 11 on the peripheral wall 16, the part to be dusted 200 can be placed in the accommodating chamber 13 from the side, thereby reducing the difficulty of transporting the part to be dusted 200; at the same time, by setting the dust exhaust port 12 on the bottom wall 15, on the one hand, the dust can be efficiently separated from the part to be dusted 200 under the action of gravity and wind, and the dust removal efficiency is high. On the other hand, the blown dust can be effectively collected by the dust collecting mechanism 30 under the action of its gravity, and the dust collection efficiency is high.

[0091] According to some embodiments of the present application, see Figure 3The dust removal bin 10 is provided with a support portion 17, and the support portion 17 is located in the accommodating cavity 13 for supporting the dust removal part 200. Along the second direction z, the blowing mechanism 20 and the dust exhaust port 12 are respectively located on two opposite sides of the support portion 17.

[0092] The support portion 17 is used to support the dust removal member 200. In some embodiments, the support portion 17 is used to support the dust removal member so that there is a distance between the dust removal member and the dust discharge port 12, so that under the action of the airflow, dust can enter the dust collection mechanism 30 through the dust discharge port 12 with less interference.

[0093] Exemplarily, the dust removal part 200 is a filter element, which includes a core body and a frame surrounding the core body, the support portion 17 is supported by the frame of the core body, and the dust exhaust port 12 is located below the core body.

[0094] “Along the second direction z, the blowing mechanism 20 and the dust exhaust port 12 are respectively located on the opposite sides of the support portion 17” can be understood as, when the part to be dusted 200 is placed in the accommodating cavity 13 and supported by the support portion 17, the blowing mechanism 20 is located on the side of the part to be dusted 200 that is away from the dust exhaust port 12, and the dust exhaust port 12 is located on the side of the part to be dusted 200 that is away from the blowing mechanism 20, that is, the blowing mechanism 20 is located directly above the part to be dusted 200, and the dust exhaust port 12 is located directly below the part to be dusted 200.

[0095] In some embodiments, the support portion 17 may be a convex ridge protruding from the bottom wall 15. In some embodiments, the middle portion of the bottom wall 15 may be concave, the dust discharge port 12 is located in the concave portion, and the support portion 17 may be a non-concave portion of the bottom wall 15.

[0096] In the above scheme, by arranging the blowing mechanism 20 and the dust exhaust port 12 on opposite sides of the support part 17, the airflow provided by the blowing mechanism 20 blows the dust on the surface of the dust removal part 200 to the dust exhaust port 12, which is beneficial for the dust collecting component to effectively collect dust, reduces the risk of dust adhering to the filter element again or splashing, and improves the dust removal efficiency.

[0097] According to some embodiments of this application, see Figure 3 The bottom wall 15 includes a flange 150 and a funnel 151. The flange 150 is arranged around the edge of the funnel 151 and is connected to the peripheral wall 16. Along the second direction z, the funnel 151 protrudes in a direction away from the top wall 14. The end of the funnel 151 away from the top wall 14 forms a dust outlet 12.

[0098] In some embodiments, the bottom wall 15 includes a flange 150 and a funnel 151. The cross-sectional area of ​​the funnel 151 gradually decreases along the direction in which the funnel 151 protrudes from the flange 150, that is, it can be understood that the expanded opening of the funnel 151 is arranged toward the top wall 14, and the contracted opening of the funnel 151 is arranged away from the top wall 14, and the contracted opening of the funnel 151 is the dust exhaust port 12. The flange 150 is arranged around the expanded edge of the funnel 151 and connected to the peripheral wall 16.

[0099] In the above scheme, by setting the funnel 151, a space can be formed below the part to be removed 200 when the part to be removed 200 is placed in the accommodating chamber 13, so that the dust blown off by the airflow can smoothly enter the funnel 151, so that the dust collecting component can effectively collect the dust, reduce the risk of dust adhering to the filter element again or splashing, and improve the dust removal efficiency and the efficiency of collecting dust.

[0100] According to some embodiments of this application, see Figure 6 , Figure 6 for Figure 5 An enlarged view of point B in FIG. Along the second direction z, the flange 150 has a first surface 1500 facing the top wall 14 , and the first surface 1500 is at least a part of the support portion 17 .

[0101] The first surface 1500 is an upper surface of the flange 150. In some embodiments, the first surface 1500 may be the support portion 17. In other embodiments, the first surface 1500 may be a portion of the support portion 17.

[0102] In some embodiments, the dust removal piece 200 is placed on the first surface 1500 and supported by the first surface 1500 .

[0103] In the above scheme, the first surface 1500 of the flange 150 can effectively support the dust-removing piece 200, and under the action of the airflow provided by the blowing mechanism 20, the dust on the surface of the dust-removing piece 200 can be blown into the funnel 151 below the dust-removing piece 200.

[0104] According to some embodiments of this application, see Figure 6 The first surface 1500 has a first edge 1501, and the first edge 1501 is connected to the edge of the funnel 151. The first surface 1500 is provided with a restraining member 18, and the restraining member 18 and the first edge 1501 are spaced apart from each other, and the restraining member 18 is used to restrain the dust-removable object 200.

[0105] In some embodiments, the flange 150 is annular, and the funnel 151 is connected to the inner ring edge of the flange 150. The first edge 1501 is the inner ring edge of the flange 150.

[0106] In some embodiments, the restraining member 18 may be a protrusion disposed on the first surface 1500, and the restraining member 18 may be disposed around the first edge 1501 and spaced from the first edge 1501. On the first surface 1500, the portion between the restraining member 18 and the first edge 1501 may be a supporting portion 17, and the dust-removed piece 200 is supported on the supporting portion 17 and restrained by the restraining member 18, thereby reducing the risk of the dust-removed piece 200 being offset.

[0107] In some embodiments, the funnel 151 is a multi-sided funnel 151, for example, a four-sided funnel 151, the inner ring of the corresponding flange 150 is a quadrilateral, and the first side 1501 has four sections and is square in shape. The restraining members 18 are in the form of strips and the number is four, and the four restraining members 18 are respectively arranged corresponding to the four sections of the first side 1501, so as to restrain the dust removal object 200 in the first direction x and the third direction y.

[0108] In some embodiments, the dust-removed part 200 is a filter element, which includes a core body and a frame surrounding the core body, and the frame is abutted by a constraint 18. In some embodiments, the first surface 1500 can also be provided with a clamping member 180, and the clamping member 180 is used to push the dust-removed part 200 against the first surface 1500 to reduce the risk of the dust-removed part 200 being offset. Exemplarily, the dust-removed part 200 is a filter element, which includes a core body and a frame surrounding the core body, and the frame has a flange, and the clamping member 180 can switch between a locked state and an open state. In the locked state, the clamping member 180 can push the flange against the first surface 1500 to fix the filter element. In the open state, the clamping member 180 can be away from the flange and the filter element can be taken. The clamping member 180 can be hinged with the first surface 1500 to flip relative to the first surface 1500, thereby switching between a locked state and an open state. In some embodiments, the clamping member 180 may include an elastic structure, and the clamping member 180 is maintained in the locked state by utilizing the elastic force of the elastic structure, and is switched to the open state by overcoming the elastic force.

[0109] In the above scheme, the position of the piece to be dusted 200 can be limited by setting the constraint member 18, so that the piece to be dusted 200 is stably located on the first surface 1500 in the airflow provided by the blowing mechanism 20, thereby reducing the risk of the piece to be dusted 200 being offset due to the impact of the airflow, resulting in the dust not being effectively blown off, thereby improving the dust removal efficiency.

[0110] According to some embodiments of the present application, a battery manufacturing system is provided, including the dust removal device 100 provided above.

[0111] In some embodiments, the battery manufacturing system includes a die-cutting tab device, the die-cutting tab device is equipped with a dust removal device for absorbing dust, and a filter element is provided in the dust removal device. After the dust removal device has been working for a period of time, dust accumulates in the filter element, the filter element is taken out and placed in the dust removal device 100 provided above for dust removal, and the dust-removed filter element is placed in the dust removal device again.

[0112] See also Figure 1-Figure 6 According to some embodiments of the present application, a dust removal device 100 is provided for cleaning a filter element.

[0113] The dust removal device 100 includes a dust removal bin 10, an air blowing mechanism 20, and a dust collecting mechanism 30. The dust removal bin 10 has a receiving chamber 13 inside, and the dust removal bin 10 is provided with a bin door 11 and a dust discharge port 12. The bin door 11 allows the filter element to enter or leave the receiving chamber 13, and the dust discharge port 12 is connected to the receiving chamber 13. The air blowing mechanism 20 is arranged in the receiving chamber 13, and is used to provide airflow to the filter element in the receiving chamber 13 to blow off the dust on the dust removal part 200. The dust collecting mechanism 30 is connected to the dust discharge port 12, and is used to provide negative pressure to the receiving chamber 13 and collect dust.

[0114] In some embodiments, the blowing mechanism 20 includes a wind knife 21 and a driving assembly 22. The number of wind knives 21 is multiple, and the multiple wind knives 21 are arranged at intervals to jointly provide airflow to the dust removal part 200. The driving assembly 22 includes a connecting portion 220, a rotating shaft 221, a gear 2220, a rack 2221 and a driving member 2222. The connecting portion 220 is connected to the dust removal bin 10, and the rotating shaft 221 is rotatably connected to the connecting portion 220. The number of rotating shafts 221 is multiple and corresponds to the wind knives 21 one by one. The wind knives 21 are fixed on the corresponding rotating shafts 221. Each rotating shaft 221 is fixed with a gear 2220. The gears 2220 of all rotating shafts 221 are meshed with a rack 2221, and the driving member 2222 drives the rack 2221 to make a linear reciprocating motion to simultaneously drive multiple gears 2220 to reciprocate, so that all wind knives 21 are reciprocatingly deflected to provide airflow at different angles to the filter element.

[0115] In the above scheme, the filter element is placed in the dust removal bin 10, and the airflow provided by the reciprocating multiple wind knives 21 and the negative pressure provided by the dust collecting mechanism 30 can, on the one hand, enable the dust on the dust removal part 200 to effectively leave the dust removal part 200, thereby efficiently cleaning and collecting the dust. On the other hand, because the dust removal work is carried out in the closed containing chamber 13, the risk of dust drifting to the external environment is low, effectively reducing the impact of dust on the environment and workers.

For those skilled in the art, the present application may have various modifications and variations.
