Cleaning device, battery processing equipment and battery processing method Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a cleaning device, battery processing equipment and a battery processing method. Background Art

[0002] During the battery manufacturing process, impurities such as foam particles and dust are easily adsorbed on the surface of the battery cells. As a result, after the battery cells are stacked to form a battery, impurities will be mixed inside the battery, affecting the battery quality.

[0003] Summary of the Invention

[0004] In view of the above problems, the embodiments of the present application provide a cleaning device, a battery processing device and a battery processing method, which can improve the problem of impurities mixed in the battery.

[0005] The technical solution adopted in the embodiment of this application is:

[0006] In a first aspect, an embodiment of the present application provides a cleaning device, comprising:

[0007] Workbench;

[0008] A cleaning member is movably arranged on the workbench;

[0009] The driving mechanism is arranged on the workbench and is used for driving the cleaning member to move so that the cleaning member can move by friction relative to the surface of the battery cell.

[0010] With such an arrangement, during the battery processing process, the cleaning member can be driven by the driving mechanism so that the cleaning member moves by friction relative to the surface of the battery cell, thereby cleaning the surface of the battery cell to remove impurities on the surface of the battery cell. This can improve the problem of impurities mixed inside the battery, thereby improving the product quality of the battery.

[0011] In some embodiments, the cleaning member is rotatably disposed on the workbench so as to be rotatable relative to the battery cell.

[0012] Such an arrangement enables the cleaning member to move frictionally relative to the surface of the battery cell to remove impurities on the surface of the battery cell.

[0013] In some embodiments, the cleaning member is movably disposed on the workbench so as to be movable relative to the battery cell.

[0014] Such an arrangement enables the cleaning member to move frictionally relative to the surface of the battery cell to remove impurities on the surface of the battery cell.

[0015] In some embodiments, the cleaning member includes a roller and multiple elastic strips. The roller is connected to the output end of the driving mechanism. The multiple elastic strips are spaced apart on the roller and are used to elastically contact the surface of the battery cell to clean the surface of the battery cell.

[0016] Such an arrangement enables the cleaning member to smoothly move in friction with the battery cell, and the cleaning member has a high force capable of removing impurities on the surface of the battery cell, thereby enabling the cleaning member to better clean the surface of the battery cell.

[0017] In some embodiments, a portion of the cleaning element is disposed within the workbench and at least partially protrudes from the surface of the workbench.

[0018] Such an arrangement facilitates the cleaning member to contact the surface of the battery cell and generate friction with the surface of the battery cell, thereby facilitating the cleaning member to clean the surface of the battery cell.

[0019] In some embodiments, the cleaning device further comprises a dust hood disposed on the workbench, wherein the dust hood is disposed opposite to the cleaning member to receive impurities cleaned by the cleaning member.

[0020] This arrangement allows the dust hood to receive impurities cleaned from the surface of the battery cell by the cleaning member. On the one hand, it can clean the entire working environment of the cleaning device. On the other hand, it can improve the problem of impurities remaining on the cleaning member, which affects the cleaning effect of the cleaning member.

[0021] In some embodiments, the cleaning device further includes a dust extraction device connected to the dust collection hood to extract impurities cleaned by the cleaning member.

[0022] In this way, the impurities removed from the surface of the battery cell by the cleaning member will not affect the cleaning effect of the entire working environment, nor will it affect the cleaning effect of the cleaning member.

[0023] In some embodiments, the cleaning device further comprises an ion air knife disposed on the workbench, the ion air knife being spaced apart from the cleaning member and configured to discharge air toward the battery cell.

[0024] In this way, static electricity on the surface of the battery cell can be eliminated, making it difficult for the surface of the battery cell to absorb impurities, thereby improving the problem of impurities being adsorbed on the surface of the battery cell and causing impurities to be mixed inside the battery.

[0025] In some embodiments, the cleaning member and the ion air knife are spaced apart along a first direction; the ion air knife has an air outlet, which is arranged toward the cleaning member in a direction inclined to the first direction and is used to discharge air toward the battery cell.

[0026] Such an arrangement enables the ion wind knife to blow ion wind toward multiple surfaces of the battery cell to eliminate static electricity on multiple surfaces of the battery cell, thereby improving the problem of impurities adsorbed on the surface of the battery cell.

[0027] In some embodiments, the cleaning member and the ion air knife are arranged at intervals along the first direction, and the ion air knife is provided on two opposite sides of the cleaning member along the first direction.

[0028] Such an arrangement enables the ion air knives on the two opposite sides of the cleaning member along the first direction to both discharge air toward the battery cell, thereby jointly eliminating static electricity on the two opposite sides of the battery cell along the first direction.

[0029] In some embodiments, the ion air knife has an air outlet, and the ion air knife is rotatably disposed on the workbench so that the direction of the air outlet can be adjusted during rotation.

[0030] This arrangement allows the ion air knife to rotate to adjust the direction of the air outlet, thereby facilitating the ion air knife to discharge air toward the battery cell through the air outlet to eliminate static electricity on the surface of the battery cell.

[0031] In some embodiments, the cleaning device further includes a rotating structure, the rotating structure including a fixed arm disposed on the workbench and a rotating arm rotatably connected to the fixed arm, and the ion air knife is disposed on the rotating arm.

[0032] In this way, the direction of the air outlet of the ion air knife can be adjusted so that the ion wind blown out by the ion air knife can eliminate static electricity on the surface of the battery cell.

[0033] In some embodiments, the fixed arm is provided with a first fixing hole, and the rotating arm is provided with a second fixing hole opposite to the first fixing hole; the first fixing hole and the second fixing hole are both spaced apart from the rotation axis of the rotating arm, and the first fixing hole and the second fixing hole are used for fixing by fasteners.

[0034] Such a setting can realize the angle adjustment and limitation of the ion air knife, and the working convenience is higher.

[0035] In some embodiments, the workbench is provided with an air outlet window for the ion air knife to discharge air, and the air outlet window is provided with a protective net.

[0036] By setting a protective net at the air outlet window, the problem of workers accidentally touching the ion air knife can be improved, thereby improving the problem of workers being injured by accidentally touching the ion air knife, thereby improving the safety performance of the cleaning device.

[0037] In some embodiments, the cleaning device further includes an ion blower, and an air outlet of the ion blower is connected to the ion air knife.

[0038] This arrangement allows static electricity on the surface of the battery cell to be eliminated by the ion wind blown out by the ion blower.

[0039] In a second aspect, an embodiment of the present application provides a battery processing device, including a cleaning device.

[0040] The battery processing equipment provided in the embodiment of the present application can remove impurities on the surface of the battery cell by adopting the cleaning device mentioned above, thereby improving the problem of impurities mixed inside the battery and thus improving the product quality of the battery.

[0041] In a third aspect, an embodiment of the present application provides a battery processing method, using battery processing equipment, comprising the following steps:

[0042] Drive the battery cells to the cleaning device;

[0043] The cleaning member of the cleaning device is driven to move so that the cleaning member moves frictionally relative to the surface of the battery cell.

[0044] The battery processing method provided in the embodiment of the present application can remove impurities on the surface of the battery cell by adopting the battery processing equipment involved above, thereby improving the problem of impurities mixed inside the battery and thus improving the product quality of the battery.

[0045] In one embodiment, the battery processing method further includes: driving the ion air knife of the cleaning device to discharge air toward the battery cell.

[0046] Such an arrangement can eliminate static electricity on the surface of the battery cell, making it difficult for the surface of the battery cell to adsorb impurities, thereby improving the problem of impurities adsorbed on the surface of the battery cell causing impurities to be mixed inside the battery.

[0047] In one embodiment, the battery processing method further includes: driving the battery cell to move along the distribution direction of the ion air knife and the cleaning member.

[0048] Such an arrangement facilitates the cleaning operation of the cleaning member on the surface of the battery cell and can achieve the effect of eliminating static electricity on multiple surfaces of the battery cell.

[0064] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.

[0065] In the battery processing technology, the battery cells are usually removed from the foam packaging first, and after testing, gluing and other operations, they are finally stacked to form a battery.

[0066] In some cases, friction between the battery cells and the foam packaging generates static electricity, making it easy for the surface of the battery cells to absorb impurities such as foam particles and dust. As a result, after the battery cells are assembled into a battery, impurities will be mixed in the battery, affecting the battery quality.

[0067] Based on the above considerations, the embodiments of the present application provide a cleaning device, a battery processing equipment and a battery processing method. In the battery processing process, the cleaning member can be driven by a driving mechanism so that the cleaning member moves frictionally relative to the surface of the battery cell, thereby cleaning the surface of the battery cell to remove impurities on the surface of the battery cell. This can improve the problem of impurities mixed inside the battery, thereby improving the product quality of the battery.

[0068] The battery involved in the embodiments of the present application can be a single physical module comprising one or more battery cells to provide higher voltage and capacity. When there are multiple battery cells, the multiple battery cells are connected in series, parallel, or in hybrid mode through a busbar. Hybrid mode refers to the multiple battery cells being connected in both series and parallel mode.

[0069] In some embodiments, the battery may be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module. For example, the multiple battery cells may be fixed to form a battery module using a rolling strip or the like. For example, the multiple battery cells may also be fixed to form a battery module using end plates, side plates, or the like.

[0070] In some embodiments, the battery may be a battery pack, which may include a housing and battery cells. As an example, the battery cells may be directly housed in the housing. As an example, the battery cells may also be formed into a battery module first and then housed in the housing.

[0071] The battery cell involved in the embodiments of the present application is a battery monomer, which refers to the smallest unit for storing and outputting electrical energy.

[0072] The battery processing equipment involved in the embodiments of the present application refers to equipment mainly used for processing batteries.

[0073] Please refer to Figure 1, which is a schematic diagram of battery processing equipment 1000 provided in some embodiments of the present application. Battery processing equipment 1000 provided in embodiments of the present application includes a cleaning device 100, which is used to clean the surface of a battery cell. The cleaning device 100 is a device capable of performing a cleaning function. The cleaning device 100 cleans the surface of the battery cell, primarily removing impurities from the surface of the battery cell.

[0074] In some embodiments, please continue to refer to Figure 1. The battery processing equipment 1000 may further include a stacking device 200, which is used to stack the battery cells cleaned by the cleaning device 100 into batteries.

[0075] Based on this, during the battery processing process, the battery cells can be first removed from the foam packaging and then transported to the cleaning device 100. The cleaning device 100 cleans the surface of the battery cells to remove impurities on the surface of the battery cells. The battery cells cleaned by the cleaning device 100 are then transported to the testing and gluing stations for corresponding testing, gluing, etc. Finally, the battery cells are transported to the stacking station, where the cleaned battery cells are stacked by the stacking device 200 to form a battery.

[0076] In this way, before the battery cells are stacked into a battery, the surface of the battery cells is cleaned by the cleaning device 100 , which can improve the problem of impurities mixed inside the battery and improve the product quality of the battery.

[0077] In some embodiments, the battery processing equipment 1000 may further include a detection device, which is used to detect the battery cells cleaned by the cleaning device 100 .

[0078] In some embodiments, the battery processing equipment 1000 may further include a gluing device for gluing the battery cells cleaned by the cleaning device 100 .

[0079] In some embodiments, referring again to FIG. 1 , the battery processing apparatus 1000 may further include a transport device 300 for transporting battery cells. The transport device 300 may transport the battery cells to the cleaning device 100 for cleaning, and may also remove the cleaned battery cells from the cleaning device 100. The transport device 300 may be, but is not limited to, a robot.

[0080] In some embodiments, please refer to Figures 2 to 4, and in combination with other drawings. Among them, Figure 2 is a partial three-dimensional structural diagram of the cleaning device 100 provided in some embodiments of the present application, Figure 3 is a partial three-dimensional structural diagram of the cleaning device 100 provided in Figure 2, and Figure 4 is a schematic diagram of the coordination of the cleaning member 10, the driving mechanism 20 and the dust cover 50 of the cleaning device 100 provided in some embodiments of the present application. The cleaning device 100 includes a workbench 30, a cleaning member 10 and a driving mechanism 20. The cleaning member 10 is movably arranged on the workbench 30. The driving mechanism 20 is arranged on the workbench 30, and the driving mechanism 20 is used to drive the cleaning member 10 to move, so that the cleaning member 10 can move relative to the surface friction of the battery cell.

[0081] The workbench 30 is a frame structure of the cleaning device 100 .

[0082] The driving mechanism 20 is a mechanism for driving the cleaning element 10 to move.

[0083] The cleaning member 10 is a component for cleaning the surface of the battery cell. In some embodiments, the cleaning member 10 can be a brush, a feather duster, or the like that can move relative to the battery cell to clean the surface of the battery cell.

[0084] When the cleaning device 100 cleans the surface of the battery cell, the cleaning member 10 contacts the surface of the battery cell, generating friction between the surface of the battery cell and the cleaning member 10. Furthermore, the cleaning member 10, driven by the driving mechanism 20, moves relative to the battery cell, and the cleaning member 10 always contacts and generates friction with the surface of the battery cell, thereby causing the cleaning member 10 to frictionally move relative to the surface of the battery cell, thereby removing impurities from the surface of the battery cell.

[0085] The cleaning device 100 provided in the embodiment of the present application can drive the cleaning member through a driving mechanism during the battery processing process, so that the cleaning member moves frictionally relative to the surface of the battery cell, thereby cleaning the surface of the battery cell to remove impurities on the surface of the battery cell. This can improve the problem of impurities mixed inside the battery, thereby improving the product quality of the battery.

[0086] Moreover, when the cleaning device 100 cleans the surface of the battery cell, the driving mechanism 20 can be controlled to start to drive the cleaning member 10 to move, and the battery cell can be transported to the cleaning member 10, so that the cleaning member 10 can clean the surface of the battery cell. The cleaning operation of the cleaning device 100 on the surface of the battery cell is very simple and easy to implement.

[0087] In some embodiments, the cleaning device 100 is mainly used to remove impurities from the bottom of the battery cell. Specifically, during the processing of the battery, the battery cell can be transported above the cleaning device 100 so that the cleaning device 100 can clean the bottom of the battery cell. The bottom of the battery cell mentioned here refers to the bottom of the battery cell during transportation. For example, during transportation, the height direction of the battery cell is parallel to the vertical direction, and the bottom of the battery cell is one end of the battery cell in the height direction. As an example, as shown in Figure 2, the cleaning device 100 is used to clean one side surface of the battery cell along the direction Z. Of course, in other embodiments, when the battery cell can be flipped during transportation, the surfaces of other sides of the battery cell can also be cleaned by the cleaning device 100. It is only necessary to flip the surface of the battery cell to be cleaned to be opposite to the cleaning device 100 so that the cleaning device 100 can clean the surface of the battery cell.

[0088] It should be noted that during the process of processing battery cells into batteries, the battery cells are usually plasma cleaned, but this can only clean part of the surface of the battery cells, and cannot completely clean all the surfaces of the battery cells. By providing the cleaning device 100, the battery cells can be cleaned by the cleaning member 10 on surfaces that may not be cleaned during the processing process, thereby improving the problem of impurities mixed in the battery.

[0089] In some embodiments, please continue to refer to FIG2 and other figures. The cleaning member 10 is rotatably disposed on the workbench 30 so as to be able to rotate relative to the battery cell.

[0090] The driving mechanism 20 is used to drive the cleaning element 10 to rotate.

[0091] When the cleaning device 100 cleans the surface of the battery cell, the cleaning member 10 contacts the surface of the battery cell, generating friction between the surface of the battery cell and the cleaning member 10. Furthermore, the cleaning member 10 can rotate about its own central axis under the drive mechanism 20, thereby rotating relative to the battery cell. During the rotation of the cleaning member 10 about its own central axis, the cleaning member 10 always maintains contact with the surface of the battery cell and generates friction, thereby causing the cleaning member 10 to frictionally move relative to the surface of the battery cell during the rotation process, allowing the cleaning member 10 to remove impurities from the surface of the battery cell.

[0092] As an example, as shown in FIG2 , when the surface of one side of the battery cell along the direction Z in the figure needs to be cleaned, the central axis of the cleaning member 10 intersects with the direction Z. For example, the central axis of the cleaning member 10 can be parallel to the direction X shown in the figure, so that when the cleaning member 10 rotates around its own central axis, the outer peripheral side of the cleaning member 10 around its own central axis can always contact the surface of the battery cell that needs to be cleaned, so that the cleaning member 10 can always maintain contact with the battery cell during the rotation process, that is, the cleaning member 10 can move frictionally relative to the surface of the battery cell to clean the surface of the battery cell that needs to be cleaned. In other examples, the central axis of the cleaning member 10 can also be parallel to the direction Y shown in the figure, and can also be parallel to a direction that intersects the direction Z, the direction X, and the direction Y.

[0093] Here, "two directions intersect" means that the two directions are not parallel, that is, the two directions form an angle greater than 0° and less than 180°. The two directions can be perpendicular to each other or not. The two directions can be intersecting directions located on the same plane, or on different planes, and the projection of one direction on the plane containing the other direction can intersect with one of the directions.

[0094] Wherein, direction Z, direction X, and direction Y are directions of three axes of the spatial coordinate axis, direction Z is perpendicular to direction Y, direction X is perpendicular to direction Z, and direction X is perpendicular to direction Y.

[0095] The driving mechanism 20 can be a motor. Alternatively, as shown in Figures 2 to 4, the driving mechanism 20 may include a motor 21 and a coupling 22, the coupling 22 being connected to the output end of the motor 21 and the cleaning member 10, and being able to drive the cleaning member 10 to rotate under the drive of the motor 21. Alternatively, the driving mechanism 20 may include a combination mechanism of a motor and a gear set. Specifically, the gear set includes a plurality of gears meshing in sequence, one of which is connected to the output shaft of the motor, and another gear is connected to the cleaning member 10. When the motor is started, the driving force of the motor can be transmitted to the cleaning member 10 in sequence through the plurality of gears of the gear set. Of course, there are many types of driving mechanism 20, which can be selected according to actual usage.

[0096] Such arrangement enables the cleaning member 10 to move frictionally relative to the surface of the battery cell to remove impurities on the surface of the battery cell.

[0097] For ease of description, in the following embodiments of the present application, the cleaning device 100 is used to clean one side surface of a battery cell along the direction Z as an example.

[0098] The direction Y is parallel to the first direction Y mentioned below. For the convenience of description, the direction Z can be set as the second direction Z, and the direction X can be set as the third direction X.

[0099] In some embodiments, the cleaning member 10 is movably disposed on the workbench so as to be movable relative to the battery cell.

[0100] The driving mechanism 20 is used to drive the cleaning member 10 to move, and may be, for example, a linear cylinder, a linear electric cylinder, or a combination of a motor and a screw mechanism.

[0101] When the cleaning device 100 cleans the surface of the battery cell, the cleaning member 10 contacts the surface of the battery cell, so that the surface of the battery cell and the cleaning member 10 are in contact and generate friction. In addition, the cleaning member 10 can be driven by the driving mechanism 20 to move relative to the battery cell. During the movement of the cleaning member 10 relative to the battery cell, the cleaning member 10 always maintains contact with the surface of the battery cell and generates friction, so that the cleaning member 10 moves frictionally relative to the surface of the battery cell during the movement, so that the cleaning member 10 can remove impurities on the surface of the battery cell.

[0102] As an example, when one side of the battery cell's surface along the second direction Z needs to be cleaned, the direction of movement of the cleaning member 10 is perpendicular to the second direction Z. For example, the cleaning member 10 can move relative to the battery cell along the third direction X, along the first direction Y, or along a direction intersecting the first direction Y and the third direction X. In this manner, the cleaning member 10 can maintain contact with the surface of the battery cell during its movement relative to the battery cell, thereby enabling frictional movement between the cleaning member 10 and the surface of the battery cell, thereby removing impurities from the surface of the battery cell.

[0103] Such arrangement enables the cleaning member 10 to move frictionally relative to the surface of the battery cell to remove impurities on the surface of the battery cell.

[0104] It is understandable that in some embodiments, the driving mechanism 20 can simultaneously drive the cleaning member 10 to rotate and move, which facilitates the cleaning member 10 to move flexibly to clean the surface of the battery cell.

[0105] In some embodiments, referring to Figures 2 to 4 in conjunction with other figures, a cleaning member 10 includes a roller 11 and a plurality of elastic strips 12. The roller 11 is connected to the output end of the drive mechanism 20. The plurality of elastic strips 12 are spaced apart from the roller 11. The elastic strips 12 are configured to elastically contact the surface of the battery cell to clean the surface of the battery cell.

[0106] The roller shaft 11 is a shaft-like structure, and is mainly used for assembling the elastic strip 12 .

[0107] The elastic strip 12 is an elastic strip structure. It can be made of a rubber strip, silicone strip, plastic strip, or other elastic material. One end of the elastic strip 12 is attached to the roller 11, and the other end is used to contact the surface of the battery cell to clean it.

[0108] The roller 11 is connected to the output end of the drive mechanism 20, so that the drive mechanism 20 drives the roller 11 to move. Specifically, the drive mechanism 20 can drive the roller 11 to rotate, causing the roller 11 and the elastic strip 12 thereon to rotate together, causing the elastic strip 12 to move frictionally relative to the surface of the battery cell. The drive mechanism 20 can also drive the roller 11 to move, causing the roller 11 and the elastic strip 12 thereon to move together, causing the elastic strip 12 to move frictionally relative to the surface of the battery cell.

[0109] Based on this, when the cleaning device 100 cleans the surface of the battery cell, the end of the elastic strip 12 away from the roller 11 contacts the surface of the battery cell to generate friction with the surface of the battery cell. Driven by the drive mechanism 20, the roller 11 moves relative to the battery cell, so that the elastic strip 12 and the surface of the battery cell move relative to each other, thereby allowing the elastic strip 12 to remove impurities on the surface of the battery cell. In this way, based on the elastic properties of the elastic strip 12, when the elastic strip 12 moves relative to the battery cell, the elastic strip 12 can elastically deform relative to the surface of the battery cell, allowing the elastic strip 12 to smoothly move relative to the battery cell, thereby allowing the elastic strip 12 to always contact the surface of the battery cell, thereby frictionally moving with the surface of the battery cell, thereby allowing the elastic strip 12 to clean the surface of the battery cell. Moreover, based on the elastic properties of the elastic strip 12, the elastic strip 12 has a certain structural strength, thereby having the strength to remove impurities on the surface of the battery cell, so as to be able to smoothly clean the surface of the battery cell.

[0110] Such an arrangement enables the cleaning member 10 to smoothly move in friction with the battery cell, and the cleaning member 10 has a high force capable of removing impurities on the surface of the battery cell, thereby enabling the cleaning member 10 to better clean the surface of the battery cell.

[0111] In some embodiments, referring to FIG. 2 to FIG. 4 and other figures, a portion of the cleaning member 10 is disposed within the workbench 30 , and at least a portion of the cleaning member 10 protrudes from the surface of the workbench 30 .

[0112] As shown in FIG2 , a portion of the cleaning member 10 is disposed within a workbench 30 . The workbench 30 has a surface 301 on one side along the second direction Z. Surface 301 is configured to face the battery cells along the second direction Z. Surface 301 defines a cleaning window 302. At least a portion of the cleaning member 10 is disposed within the cleaning window 302 and extends beyond the surface 301 along the second direction Z through the cleaning window 302. Thus, when a battery cell is positioned on the side of the workbench 300 with the surface 301, the portion of the cleaning member 10 extending beyond the surface 301 along the second direction Z can contact the battery cell and rub against it, thereby enabling the cleaning member 10 to clean the surface of the battery cell.

[0113] This arrangement facilitates the cleaning member 10 to contact and rub against the surface of the battery cell, thereby facilitating the cleaning of the battery cell surface by the cleaning member 10. Furthermore, the cleaning member 10 is partially disposed within the workbench 30, thereby alleviating the problem of impurities removed by the cleaning member 10 being splashed, thereby achieving a cleaning effect on the working environment of the battery processing.

[0114] In some embodiments, the transporting device 300 can transport the battery cell so that the battery cell moves relative to the cleaning device 100, and can make the battery cell move relative to the cleaning member 10 of the cleaning device 100, so that the surface of the battery cell moves frictionally relative to the cleaning member 10, thereby achieving the effect of the cleaning member 10 cleaning the surface of the battery cell.

[0115] As an example, when the surface of a battery cell along one side of the second direction Z in the figure needs to be cleaned, the transport device 300 drives the battery cell to move in a direction perpendicular to the second direction Z. For example, the transport device 300 can move the battery cell relative to the cleaning member 10 along the first direction Y, along the third direction X, or along a direction intersecting the third direction X and the first direction Y. In this manner, the cleaning member 10 can maintain contact with the surface of the battery cell during movement relative to the cleaning member 10, allowing the cleaning member 10 to frictionally move relative to the surface of the battery cell, thereby removing impurities from the surface of the battery cell.

[0116] Wherein, the transport device 300 is used to transport the battery cell and when the cleaning member 10 is capable of rotating relative to the battery cell, the rotation direction of the cleaning member 10 at the position in contact with the surface of the battery cell and the moving direction of the battery cell need to be set to be opposite. When the rotation direction of the cleaning member 10 at the position in contact with the surface of the battery cell is the same as the moving direction of the battery cell, the rotational linear speed of the cleaning member 10 and the moving speed of the battery cell need to be set to be different. The transport device 300 is used to transport the battery cell and when the cleaning member 10 is capable of rotating relative to the battery cell, the moving directions of the cleaning member 10 and the battery cell need to be set to be opposite. When the moving direction of the cleaning member 10 is the same as the moving direction of the battery cell, the moving speed of the cleaning member 10 and the moving speed of the battery cell need to be set to be different.

[0117] As an example, the transport device 300 is used to move the battery cells along a first direction Y, and the cleaning member 10 is configured to rotate. Furthermore, the direction of rotation of the cleaning member 10, when in contact with the surface of the battery cells, is opposite to the direction of movement of the battery cells. This allows the cleaning member 10 to clean the side of the battery cells facing the cleaning member 10 along a second direction Z.

[0118] While the cleaning device 100 is cleaning the surface of the battery cell, the transport device 300 transports the battery cell to one side of the cleaning member 10 along the second direction Z. Furthermore, the transport device 300 drives the battery cell to move along the first direction Y. At this time, the cleaning member 10 rotates about its central axis, which is parallel to the second direction Z. The direction of rotation of the cleaning member 10 at the point of contact with the surface of the battery cell is opposite to the direction of movement of the battery cell. In this manner, the cleaning member 10 can clean the surface of the battery cell along the second direction Z that faces the cleaning member 10.

[0119] Such an arrangement facilitates the cleaning member 10 to clean the surface of the battery cell, thereby facilitating the removal of impurities on the surface of the battery cell, and can improve the problem of impurities mixed inside the battery.

[0120] In some embodiments, please refer to Figures 3 and 4 together with other figures. The cleaning device 100 further includes a dust hood 50 disposed on the workbench 30. The dust hood 50 is disposed opposite to the cleaning member 10 to receive impurities cleaned by the cleaning member 10.

[0121] The dust hood 50 refers to a cover structure that can be used to receive impurities. Specifically, the dust hood 50 has a dust suction port 501. The dust hood 50 is arranged relative to the cleaning member 10, which means that the dust suction port 501 of the dust hood 50 is arranged towards the cleaning member 10.

[0122] Based on this, when the cleaning device 100 cleans the surface of the battery cell, the cleaning member 10 removes impurities on the surface of the battery cell, and the dust cover 50 receives the impurities removed by the cleaning member 10. This can improve the problem of impurities removed by the cleaning member 10 being scattered to various locations.

[0123] As an example, as shown in Figures 3 and 4, the dust hood 50 is disposed on one side of the cleaning member 10 along the first direction Y. In other examples, the dust hood 50 can also be disposed on two opposite sides of the cleaning member 10 along the first direction Y, or on a side of the cleaning member 10 away from the battery cell along the second direction Z, or on one or both sides of the cleaning member 10 along the third direction X, or even on one or both sides of the cleaning member 10 along a direction intersecting the first direction Y, the second direction Z, and the third direction X.

[0124] Such a configuration allows the dust hood 50 to receive impurities cleaned from the surface of the battery cell by the cleaning member 10. On the one hand, it can achieve a cleaning effect on the entire working environment of the cleaning device 100. On the other hand, it can improve the problem of impurities remaining on the cleaning member 10, which affects the cleaning effect of the cleaning member 10.

[0125] In some embodiments, the cleaning device 100 further includes a dust extraction device connected to the dust collection hood 50 to extract impurities cleaned by the cleaning member 10 .

[0126] The dust extraction device refers to a device having suction force to extract impurities from the dust collection cover 50. For example, the dust extraction device can be a device having suction force, such as a vacuum cleaner, an exhaust fan, or an air pump.

[0127] It is understandable that the dust hood 50 further includes a dust outlet 502 , and the dust inlet 501 and the dust outlet 502 of the dust hood 50 are connected. In addition, the dust extraction device is connected to the dust outlet 502 of the dust hood 50 .

[0128] Based on this, while the cleaning device 100 is cleaning the surface of the battery cell, the dust extraction device is turned on to perform dust extraction, so that the impurities cleaned from the surface of the battery cell by the cleaning member 10 pass through the dust suction port 501 and the dust outlet 502 of the dust collection cover 50 in sequence, and are then extracted from the cleaning member 10 under the dust extraction action of the dust extraction device. In this way, the impurities removed from the surface of the battery cell by the cleaning member 10 will not affect the cleaning effect of the entire working environment, nor will it affect the cleaning effect of the cleaning member 10.

[0129] In some embodiments, referring to Figures 2 to 4 in conjunction with other figures, the cleaning device 100 further includes an ion air knife 40 disposed on the workbench 30. The ion air knife 40 is spaced apart from the cleaning member 10 and is configured to discharge air toward the battery cells.

[0130] The ion air knife 40 is a device for blowing out ion air to eliminate static electricity.

[0131] By providing the ion air knife 40, when the cleaning device 100 is cleaning impurities on the surface of the battery cell, the ion air knife 40 can discharge air toward the surface of the battery cell to eliminate static electricity on the surface of the battery cell. This can make the surface of the battery cell less likely to absorb impurities, thereby improving the problem of impurities adsorbed on the surface of the battery cell causing impurities to be mixed into the battery interior.

[0132] In some embodiments, referring to Figures 2 to 4 in conjunction with other figures, the cleaning member 10 and the ion air knife 40 are spaced apart along a first direction Y. The ion air knife 40 has an air outlet 401, which is arranged toward the cleaning member 10 in a direction oblique to the first direction Y and is used to discharge air toward the battery cells.

[0133] When the ion wind knife 40 blows out the ion wind, the ion wind is blown out from the air outlet 401 .

[0134] In the process of cleaning the battery cell by the cleaning device 100, the battery cell is arranged on one side of the cleaning member 10 along the second direction Z to clean the side of the battery cell facing the cleaning member 10 along the second direction Z. The air outlet 401 of the ion wind knife 40 is arranged toward the cleaning member 10 along a direction inclined to the first direction Y, and is used to discharge air toward the battery cell. Based on this, it can be understood that the air outlet 401 is arranged toward the battery cell in a direction intersecting the first direction Y and the second direction Z, that is, the ion wind knife 40 can discharge air toward the battery cell in a direction intersecting the first direction Y and the second direction Z, such as the direction a shown in Figures 2 and 3. With such a configuration, the ion wind knife 40 can blow ion wind toward the surface of one side of the battery cell facing the cleaning member 10 along the second direction Z to eliminate static electricity on the surface of the one side of the battery cell facing the cleaning member 10 along the second direction Z. In addition, the ion wind knife 40 can also blow ion wind toward the side of the battery cell along the first direction Y to eliminate static electricity on the side of the battery cell along the first direction Y.

[0135] Such an arrangement enables the ion wind knife 40 to blow ion wind toward multiple surfaces of the battery cell to eliminate static electricity on multiple surfaces of the battery cell, thereby improving the problem of impurities adsorbed on the surface of the battery cell.

[0136] It will be appreciated that the transport device 300 is configured so that the battery cell can be moved relative to the cleaning member 10 in the first direction Y. With this configuration, the battery cell can be moved relative to the cleaning member 10 in the first direction Y, causing the side surface of the battery cell facing the cleaning member 10 in the second direction Z to rub against the cleaning member 10, thereby enabling the cleaning member 10 to clean the side surface of the battery cell facing the cleaning member 10 in the second direction Z, thereby assisting in the cleaning operation in step S20. Furthermore, the movement of the battery cell in the first direction Y can be moved until the battery cell is directly opposite the ion air knife 40 in the second direction Z. In this way, the ion air knife 40 can blow ion air toward the side of the battery cell facing the cleaning member 10 in the second direction Z, thereby eliminating static electricity on the side surface of the battery cell facing the cleaning member 10 in the second direction Z. Furthermore, the battery cell can be moved until the battery cell and the ion air knife 40 are offset, at which point the ion air knife 40 can blow ion air toward the side of the battery cell in the first direction Y, thereby eliminating static electricity on the side surface of the battery cell in the first direction Y. Such an arrangement can achieve the effect of eliminating static electricity on multiple surfaces of the battery cell.

[0137] In some embodiments, referring to FIG2 and FIG3 together with other figures, the cleaning member 10 and the ion air knife 40 are arranged at intervals along the first direction Y, and the ion air knife 40 is provided on opposite sides of the cleaning member 10 along the first direction Y.

[0138] It can be understood that the ion air knife 40 is provided in two groups, and the two groups of ion air knife 40 are respectively provided on opposite sides of the cleaning member 10 along the first direction Y. Each group of ion air knife 40 may include at least one ion air knife 40 .

[0139] Such an arrangement enables the ion air knives 40 on opposite sides of the cleaning member 10 along the first direction Y to discharge air toward the battery cell, thereby jointly eliminating static electricity on the opposite sides of the battery cell along the first direction Y.

[0140] In some embodiments, the transport device 300 can be used to transport the battery cells. Specifically, the transport device 300 can transport the battery cells along the first direction Y.

[0141] Based on this, during the process of the cleaning device 100 cleaning the battery cell, the transport device 300 can first transport the battery cell to the side of the first ion air knife 40 along the second direction Z, so that the side surface of the battery cell facing the first ion air knife 40 along the second direction Z faces the ion air knife 40. At this time, the first ion air knife 40 blows ion wind toward the side surface of the battery cell along the second direction Z toward the first ion air knife 40 to eliminate static electricity on the side surface of the battery cell along the second direction Z toward the first ion air knife 40. The battery cell is located on the same side of the ion air knife 40 and the cleaning member 10 along the second direction Z, that is, the side surface of the battery cell along the second direction Z facing the ion air knife 40 is the same surface as the side surface of the battery cell along the second direction Z facing the cleaning member 10. Then, the transport device 300 transports the battery cell along the first direction Y to move the battery cell along the first direction Y toward the cleaning member 10, so that the battery cell gradually staggers with the first ion air knife 40. At this time, the first ion wind knife 40 continues to blow ion wind toward one side of the battery cell along the first direction Y to eliminate static electricity on the surface of one side of the battery cell along the first direction Y. The second ion wind knife 40 blows ion wind toward the other side of the battery cell along the first direction Y to eliminate static electricity on the surface of the other side of the battery cell along the first direction Y. In addition, the battery cell moves frictionally relative to the cleaning member 10, so that the cleaning member 10 removes impurities on the surface of the battery cell along the second direction Z toward the cleaning member 10. Finally, the transport device 300 transports the battery cell along the first direction Y to one side of the second direction Z of the second ion wind knife 40, and the second ion wind knife 40 blows ion wind toward the side of the battery cell along the second direction Z toward the first ion wind knife 40 to eliminate static electricity on the surface of the battery cell along the second direction Z toward the first ion wind knife 40. This arrangement can better remove impurities and static electricity on the surface of the battery cell, so as to improve the problem of impurities adsorbed on the surface of the battery cell causing impurities to be mixed inside the battery.

[0142] Of course, according to actual usage requirements, if the static electricity on the side of the battery cell facing the cleaning member 10 along the second direction Z does not need to be eliminated, it is also possible not to move the battery cell to face the ion air knife 40 along the second direction Z. The battery cell can be directly moved to the opposite sides of the cleaning member 10 along the first direction Y and located between the two ion air knives 40. In this case, the cleaning member 10 achieves a cleaning effect on the side of the battery cell facing the cleaning member 10 along the second direction Z, and the ion air knives 40 on the opposite sides of the cleaning member 10 are used to blow ion air toward the opposite sides of the battery cell along the first direction Y, respectively, to eliminate static electricity on the opposite sides of the battery cell along the first direction Y.

[0143] In some embodiments, please refer to Figures 2 to 5 in conjunction with other figures. Figure 5 shows a partial enlarged view of Figure 3. The ion air knife 40 has an air outlet 401. The ion air knife 40 is rotatably mounted on the workbench 30 so that the direction of the air outlet 401 can be adjusted during rotation.

[0144] Specifically, the ion air knife 40 is rotatably connected to the workbench 30 .

[0145] The air outlet 401 of the ion air knife 40 is arranged toward the battery cell, and the direction of the air outlet 401 can be adjusted when the ion air knife 40 rotates.

[0146] Such an arrangement allows the ion air knife 40 to rotate to adjust the direction of the air outlet 401 , thereby facilitating the ion air knife 40 to discharge air toward the battery cell through the air outlet 401 to eliminate static electricity on the surface of the battery cell.

[0147] As an example, as shown in Figures 2 and 3, the ion air knife 40 is configured to rotate around its own central axis. The rotation axis of the ion air knife 40 is parallel to the third direction X.

[0148] In some embodiments, referring to FIG. 3 and FIG. 5 in conjunction with other figures, the cleaning device 100 further includes a rotating structure 60. The rotating structure 60 includes a fixed arm 61 and a rotating arm 62. The fixed arm 61 is disposed on the workbench 30, and the rotating arm 62 is rotatably connected to the fixed arm 61. The ion air knife 40 is disposed on the rotating arm 62.

[0149] The fixed arm 61 is a component for connecting the workbench 30 and the rotating arm 62 . The rotating arm 62 is a component for connecting to the fixed arm 61 and the ion air knife 40 and capable of rotating relative to the fixed arm 61 .

[0150] By setting a fixed arm 61 and a rotating arm 62, the rotating arm 62 can rotate relative to the fixed arm 61, so that the ion wind knife 40 set on the rotating arm 62 can rotate relative to the workbench 30, so that the direction of the air outlet 401 of the ion wind knife 40 can be adjusted, so that the ion wind blown out by the ion wind knife 40 can eliminate the static electricity on the surface of the battery cell.

[0151] In some embodiments, referring to Figures 3 and 5 in conjunction with other figures, the fixed arm 61 is provided with a first fixing hole 601, and the rotating arm 62 is provided with a second fixing hole 602 opposite the first fixing hole 601. The first fixing hole 601 and the second fixing hole 602 are both spaced apart from the rotation axis of the rotating arm 62 and are used for fastening via fasteners.

[0152] In some possible designs, the first fixing hole 601 is arc-shaped; in some possible designs, the second fixing hole 602 is arc-shaped; in some possible designs, both the first fixing hole 601 and the second fixing hole 602 are arc-shaped. It can be understood that the arc-shaped setting of the first fixing hole 601 and / or the second fixing hole 602 allows the second fixing hole 602 on the rotating arm 62 to maintain a relative state with the first fixing hole 601 during the rotation of the rotating arm 62 relative to the fixed arm 61. In this way, after the rotating arm 62 rotates to the appropriate position, the fastener can pass through the relative first fixing hole 601 and the second fixing hole 602 in sequence to fix the fixed arm 61 and the rotating arm 62, thereby achieving the position limitation of the ion air knife 40 on the workbench 30. Correspondingly, the fastener can be loosened, and the ion air knife 40 can be driven to rotate by the rotating arm 62 to adjust the direction of the air outlet 401 of the ion air knife 40.

[0153] The fasteners may be components with fastening functions such as bolts and screws.

[0154] Such an arrangement can realize the angle adjustment and position limiting of the ion air knife 40, and the working convenience is high.

[0155] In some embodiments, referring to FIG. 2 and in conjunction with other figures, the workbench 30 is provided with an air outlet window 303 for the ion air knife 40 to discharge air. The air outlet window 303 is provided with a protective net 70 .

[0156] As can be understood, the workbench 30 has a tabletop 301 on one side along the second direction Z. The tabletop 301 is configured to face the battery cells along the second direction Z. An air outlet window 303 is defined on the tabletop 301 of the workbench 30, and the air outlet 401 of the ion air knife 40 faces the air outlet window 303. Therefore, when the ion air knife 40 blows ionized air through the air outlet 401, the ionized air is blown out of the tabletop 301 through the air outlet window 303 and toward the battery cells.

[0157] The protective net 70 is a mesh structure used to provide protection.

[0158] By providing a protective net 70 at the air outlet window 303 , the problem of workers accidentally touching the ion air knife 40 can be improved, thereby improving the problem of workers being injured by accidentally touching the ion air knife 40 , thereby improving the safety performance of the cleaning device 100 .

[0159] In some embodiments, the cleaning device 100 further includes an ion blower, and an air outlet of the ion blower is connected to the ion air knife 40 .

[0160] The ion blower is a device for blowing ion air. The ion blower is connected to the ion air knife 40. Based on this, the ion air blown by the ion blower can be blown out through the ion air knife 40 to blow towards the battery cell, thereby eliminating static electricity on the surface of the battery cell.

[0161] This arrangement allows static electricity on the surface of the battery cell to be eliminated by the ion wind blown out by the ion blower.

[0162] Based on the above concept, the present application also provides a battery processing device 1000, which includes a cleaning device 100. The cleaning device 100 in this embodiment is the same as the cleaning device 100 in the previous embodiment. For details, please refer to the relevant description of the cleaning device 100 in the previous embodiment, which will not be repeated here.

[0163] The battery processing equipment 1000 provided in an embodiment of the present application is configured to include a cleaning device 100 for cleaning the surface of a battery cell. Thus, during the battery processing process, the cleaning device 100 can be used to clean the surface of the battery cell to remove impurities on the surface of the battery cell, thereby improving the problem of impurities mixed in the battery and thus improving the product quality of the battery.

[0164] Based on the above concept, please refer to Figure 6 in conjunction with other accompanying drawings. Figure 6 is a flow chart of a battery processing method provided in some embodiments of the present application. The present application also provides a battery processing method, which uses a battery processing device 1000. The battery processing device 1000 in this embodiment is the same as the battery processing device 1000 in the previous embodiment. For details, please refer to the relevant description of the battery processing device 1000 in the previous embodiment, which will not be repeated here.

[0165] In this embodiment, the battery processing method includes the following steps:

[0166] S10, driving the battery cell to be transported to the cleaning device 100;

[0167] The transport device 300 can be controlled to transport the battery cell to the cleaning device 100. Specifically, the transport device 300 transports the battery cell to one side of the cleaning member 10 of the cleaning device 100 along the second direction Z, so that one side of the battery cell along the second direction Z can face the cleaning member 10, so that the cleaning member 10 can clean the surface of the battery cell along the second direction Z facing the cleaning member 10.

[0168] S20 , driving the cleaning member 10 of the cleaning device 100 to move, so that the cleaning member 10 moves frictionally relative to the surface of the battery cell.

[0169] Among them, the driving mechanism 20 of the cleaning device 100 can be used to drive the cleaning member 10 to move so that the cleaning member 10 moves relative to the surface of the battery cell by friction, thereby removing impurities on the surface of the battery cell. As an example, as shown in the figure, the driving mechanism 20 can drive the roller 11 of the cleaning member 10 to rotate so that the elastic strip 12 on the roller 11 rotates together with the roller 11, thereby moving relative to the surface of the battery cell by friction, so as to clean the surface of the battery cell. As an example, the driving mechanism 20 can also drive the cleaning member 10 to move so that the cleaning member 10 moves relative to the surface of the battery cell by friction. In addition, the battery cell can also be moved by the transport device 300 so that the battery cell moves relative to the cleaning member 10 by friction.

[0170] The battery processing method provided in the embodiment of the present application can remove impurities on the surface of the battery cell by adopting the battery processing equipment 1000 involved in the above embodiments, thereby improving the problem of impurities mixed inside the battery and thus improving the product quality of the battery.

[0171] In some embodiments, after driving the cleaning device 100 to clean the surface of the battery cell, the following steps may also be performed:

[0172] S30 , driving the stacking device 200 to stack the battery cells cleaned by the cleaning device 100 .

[0173] This arrangement allows the battery cells cleaned by the cleaning device 100 to be stacked to form a battery, thereby alleviating the problem of impurities mixed inside the battery.

[0174] In some embodiments, the battery processing method further comprises:

[0175] S40 , driving the ion air knife 40 of the cleaning device 100 to discharge air toward the battery cell.

[0176] Step S40 can be performed simultaneously with step S20, that is, while the cleaning member 10 of the cleaning device 100 cleans the surface of the battery cell, the ion air knife 40 blows ion air toward the battery cell to eliminate static electricity on the surface of the battery cell. Step S40 can also be performed before or after step S20.

[0177] Such an arrangement can eliminate static electricity on the surface of the battery cell, making it difficult for the surface of the battery cell to adsorb impurities, thereby improving the problem of impurities adsorbed on the surface of the battery cell causing impurities to be mixed inside the battery.

[0178] In some embodiments, the battery processing method further comprises:

[0179] S50 , driving the electric core to move along the distribution direction of the ion air knife 40 and the cleaning member 10 .

[0180] In this step, the transport device 300 drives the battery cells to move.

[0181] Among them, step S50 can be performed simultaneously with step 20 and step 40, that is, step S50 is performed simultaneously with step S20 and step 40. It can be understood that during the process of the cleaning member 10 cleaning the surface of the battery cell, the battery cell moves along the distribution direction of the ion air knife 40 and the cleaning member 10, and the ion air knife 40 blows ion air toward the battery cell to eliminate static electricity on the surface of the battery cell.

[0182] It should be noted that the distribution direction of the ion air knife 40 and the cleaning member 10 is parallel to the first direction Y.

[0183] While the cleaning member 10 is cleaning the side surface of the battery cell facing the cleaning member 10 along the second direction Z, the battery cell can move relative to the cleaning member 10 along the first direction Y, so that the side surface of the battery cell facing the cleaning member 10 along the second direction Z and the cleaning member 10 rub against each other, thereby enabling the cleaning member 10 to clean the side surface of the battery cell facing the cleaning member 10 along the second direction Z. That is, step S50 is performed simultaneously with step S20, which can assist in achieving the cleaning operation of step S20.

[0184] While the ion air knife 40 blows ion air toward the battery cell, the battery cell moves along the first direction Y, so that the battery cell is directly opposite the ion air knife 40 along the second direction Z. In this way, the ion air knife 40 can blow ion air toward the side of the battery cell along the second direction Z that faces the cleaning member 10, thereby eliminating static electricity on the surface of the battery cell on the side that faces the cleaning member 10 along the second direction Z. Furthermore, the battery cell can also be moved to a state where the battery cell and the ion air knife 40 are offset. In this case, the ion air knife 40 can blow ion air toward the side of the battery cell along the first direction Y, thereby eliminating static electricity on the side of the battery cell along the first direction Y. With this configuration, step S40 and step S50 are performed simultaneously, which can achieve the effect of eliminating static electricity on multiple surfaces of the battery cell.

[0185] Such a configuration facilitates the cleaning operation of the cleaning member 10 on the surface of the battery cell and can achieve the effect of eliminating static electricity on multiple surfaces of the battery cell.

[0186] As one embodiment of the present application, as shown in Figures 1 to 5, a battery processing apparatus 1000 includes a cleaning device 100, a transport device 300, and a stacking device 200. The cleaning device 100 is used to clean impurities from the surface of battery cells, and the stacking device 200 is used to stack the battery cells cleaned by the cleaning device 100 to form a battery. The cleaning device 100 includes a workbench 30, a drive mechanism 20, a cleaning member 10, and two sets of ion air knives 40. The drive mechanism 20, the cleaning member 10, and the two sets of ion air knives 40 are all disposed on the workbench 30, and the two sets of ion air knives 40 are spaced apart on opposite sides of the cleaning member 10 along a first direction Y.
