In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not require further discussion in subsequent drawings.

[0029] As Figures 1 to 3 shown, the cell cleaning device of this embodiment is used to remove debris on the surface of the cell 1. The cell cleaning device includes: a frame 10, a driving assembly 20, a cleaning assembly 30, and a suction assembly 40. The driving assembly 20 is arranged on the frame 10. The cleaning assembly 30 is arranged at the bottom of the frame 10, and the driving assembly 20 drives the cleaning assembly 30 to rotate to remove impurities on the surface of the cell 1. The suction assembly 40 covers the outer periphery of the frame 10 to suck up impurities.

[0030] Applying the technical solution of this embodiment, a driving component 20 is arranged on the frame 10. A cleaning component 30 is arranged at the bottom of the frame 10. The driving component 20 drives the cleaning component 30 to rotate, and the cleaning component 30 removes impurities on the surface of the battery cell 1. An absorption component 40 is arranged outside the periphery of the frame 10, and the absorption component 40 absorbs the impurities cleaned by the cleaning component 30. Through the above settings, the frame 10 can support the driving component 20 and the cleaning component 30. The driving component 20 can drive the cleaning component 30 to rotate, and then the cleaning component 30 can rotate. When the cleaning component 30 rotates, it contacts the surface of the battery cell 1 and removes the impurities on the surface of the battery cell 1. The absorption component 40 can absorb impurities. The absorption component 40 is arranged outside the periphery of the frame 10, so that after the impurities on the surface of the battery cell 1 are removed, they can be absorbed by the absorption component 40, avoiding the impurities floating outside the absorption component 40 and also avoiding the impurities adhering to the surface of the battery cell 1 again, improving the cleaning effect of the battery cell 1 cleaning device. The absorption component 40 can also absorb the impurities adsorbed on the surface of the cleaning component 30, avoiding the impurities remaining on the surface of the cleaning component 30, and then avoiding that after the cleaning component 30 cleans multiple battery cells 1, due to the impurities being easily adsorbed on the surface of the cleaning component 30, the cleaning effect of the cleaning component 30 is affected. Therefore, the technical solution of this embodiment effectively solves the problem of poor dust removal effect caused by impurities being easily adsorbed on the surface of the cleaning tool after long-term cleaning in the related art.

[0031] It should be noted that after the cleaning component 30 removes impurities, some impurities will float, and another part of the impurities will be adsorbed on the surface of the cleaning component 30. The absorption component 40 can absorb impurities, which means that the absorption component 40 can not only absorb the floating impurities, but also absorb the impurities adsorbed on the surface of the cleaning component 30.

[0032] The cleaning component 30 of this embodiment has a flexible characteristic, that is, the cleaning component 30 can deform during use and will not cause damage to the surface of the battery cell 1.

[0033] As Figure 1 shown, in this embodiment, the cleaning component 30 includes a first cleaning roller 31 and a second cleaning roller 32, and there is an included angle between the rotation axis of the first cleaning roller 31 and the rotation axis of the second cleaning roller 32. The first cleaning roller 31 and the second cleaning roller 32 can better remove the impurities on the surface of the battery cell 1. There is an included angle between the rotation axis of the first cleaning roller 31 and the rotation axis of the second cleaning roller 32, so that the first cleaning roller 31 and the second cleaning roller 32 can clean different positions of the battery cell 1, making the cleaning effect of the battery cell cleaning device better.

[0034] In other embodiments, the rotation axes of the first cleaning roller 31 and the second cleaning roller 32 are parallel, and the first cleaning roller 31 and the second cleaning roller 32 can successively clean the surface of the battery cell 1, so that the cleaning effect of the battery cell cleaning device is better.

[0035] As Figure 2 shown, in this embodiment, the cleaning assembly 30 further includes a third cleaning roller 33 and a fourth cleaning roller 34. There is an included angle between the rotation axis of the first cleaning roller 31 and the rotation axis of the second cleaning roller 32. The first cleaning roller 31 and the third cleaning roller 33 are oppositely arranged, the second cleaning roller 32 and the fourth cleaning roller 34 are oppositely arranged, the rotation direction of the first cleaning roller 31 is the same as that of the third cleaning roller 33, and the rotation direction of the second cleaning roller 32 is the same as that of the fourth cleaning roller 34. The first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, and the fourth cleaning roller 34 can clean the surface of the battery cell 1 facing the battery cell cleaning device, improving the cleaning effect of the battery cell cleaning device. The rotation direction of the first cleaning roller 31 is the same as that of the third cleaning roller 33, and the rotation direction of the second cleaning roller 32 is the same as that of the fourth cleaning roller 34, making the gas flow in the suction assembly 40 more reasonable. Furthermore, after the debris on the surface of the battery cell 1 is removed, it can be more easily sucked by the suction assembly 40, preventing the debris from floating outside the suction assembly 40.

[0036] In this embodiment, the rotation axes of the first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, and the fourth cleaning roller 34 are on the same horizontal plane, which can more effectively clean the surface of the battery cell 1.

[0037] Specifically, the first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, and the fourth cleaning roller 34 of this embodiment have flexible characteristics, that is, the first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, and the fourth cleaning roller 34 can deform during use and will not damage the surface of the battery cell 1. Under the combined action of the first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, and the fourth cleaning roller 34, the cleaning assembly 30 can cover a larger area of the surface of the battery cell 1. The angle change of the bristles on the surfaces of the first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, and the fourth cleaning roller 34 is parallel to debris such as lint and dust, resulting in more thorough cleaning and the ability to clean impurities with larger particle sizes.

[0038] It should be noted that in other embodiments, the first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, and the fourth cleaning roller 34 may also have rigid characteristics. At this time, the first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, and the fourth cleaning roller 34 rotate at high speed to generate airflow, and the impurities on the surface of the battery cell 1 flow away from the surface of the battery cell 1 along with the airflow.

[0039] As Figure 2 and Figure 3 shown, in this embodiment, the driving assembly 20 includes a driving member, a first rotating member 21, and a second rotating member 22. The driving member is drivingly connected to the first rotating member 21, and the second rotating member 22 meshes with the first rotating member 21. The driving member drives the first rotating member 21 to rotate and drives the second rotating member 22 to rotate. The first rotating member 21 drives the second cleaning roller 32 and the third cleaning roller 33 to rotate, and the second rotating member 22 rotates to drive the first cleaning roller 31 and the fourth cleaning roller 34 to rotate. The first rotating member 21 can drive the second cleaning roller 32 and the third cleaning roller 33 to rotate, and can also drive the second rotating member 22 to rotate. The rotation of the second rotating member 22 can drive the first cleaning roller 31 and the fourth cleaning roller 34, so as to realize the cleaning of the surface of the battery cell 1 by the cleaning assembly 30.

[0040] Preferably, the driving member is a driving motor. The first rotating member 21 is a first circular gear, and the second rotating member 22 is a second circular gear. Of course, in an embodiment not shown in the figure, the gear transmission between the first rotating member 21 and the second rotating member 22 can be replaced by a belt transmission.

[0041] As Figure 2 and Figure 3As shown, in this embodiment, the driving assembly 20 further includes a first rotating rod 23 and a first driving wheel 24 disposed on the first rotating rod 23. The first rotating member 21 rotates to drive the first rotating rod 23 to rotate. The first rotating rod 23 rotates in the same direction as the first rotating member 21. A first driven wheel 321 is disposed on one side of the second cleaning roller 32 facing the third cleaning roller 33. The first driving wheel 24 meshes with the first driven wheel 321. A second driven wheel 331 is disposed on one side of the third cleaning roller 33 facing the second cleaning roller 32. The first driving wheel 24 meshes with the second driven wheel 331. The driving assembly 20 further includes a second rotating rod 25 and a second driving wheel 26 disposed on the second rotating rod 25. The second rotating member 22 rotates to drive the second rotating rod 25 to rotate. The second rotating rod 25 rotates in the same direction as the second rotating member 22. A third driven wheel 311 is disposed on one side of the first cleaning roller 31 facing the fourth cleaning roller 34. The second driving wheel 26 meshes with the third driven wheel 311. A fourth driven wheel 341 is disposed on one side of the fourth cleaning roller 34 facing the first cleaning roller 31. The second driving wheel 26 meshes with the fourth driven wheel 341. The first driving wheel 24 meshes with both the first driven wheel 321 and the second driven wheel 331. When the first rotating rod 23 rotates to drive the first driving wheel 24 to rotate, the first driven wheel 321 and the second driven wheel 331 can rotate, and further the second cleaning roller 32 and the third cleaning roller 33 can rotate, so as to realize the cleaning of the surface of the battery cell 1. The second driving wheel 26 meshes with the third driven wheel 311 and the fourth driven wheel 341. When the second rotating rod 25 drives the second driving wheel 26 to rotate, the third driven wheel 311 and the fourth driven wheel 341 can rotate, and further the first cleaning roller 31 and the fourth cleaning roller 34 can rotate, so as to realize the cleaning of the surface of the battery cell 1.

[0042] As Figures 2 to 4 shown, in this embodiment, the first driving wheel 24 is a first bevel gear 241, the first driven wheel 321 is a second bevel gear 3211, the second driven wheel 331 is a third bevel gear 3311, the second driving wheel 26 is a fourth bevel gear 261, the third driven wheel 311 is a fifth bevel gear 3111, and the fourth driven wheel 341 is a sixth bevel gear 3411. By meshing the first bevel gear 241 with the second bevel gear 3211 and the third bevel gear 3311, the first bevel gear 241 can drive the second bevel gear 3211 and the third bevel gear 3311 to rotate simultaneously when the first bevel gear 241 rotates. By meshing the fourth bevel gear 261 with the fifth bevel gear 3111 and the sixth bevel gear 3411, the fourth bevel gear 261 can drive the fifth bevel gear 3111 and the sixth bevel gear 3411 to rotate simultaneously when the fourth bevel gear 261 rotates.

[0043] As Figure 2As shown, in this embodiment, the battery cell cleaning device further includes a first transmission member 50 disposed between the first rotating member 21 and the first rotating rod 23. The battery cell cleaning device further includes a second transmission member 60 disposed between the first rotating member 21 and the first rotating rod 23. When the first rotating member 21 rotates, it can drive the first rotating rod 23 to rotate through the first transmission member 50. When the second rotating member 22 rotates, it can drive the second rotating rod 25 to rotate through the second transmission member 60.

[0044] Preferably, in this embodiment, the first transmission member 50 is a first belt, and the second transmission member 60 is a second belt.

[0045] As Figure 2 and Figure 3 As shown, in this embodiment, the first cleaning roller 31 includes a shaft body 312 rotatably connected to the frame 10 and a brush 313. The shaft body 312 is connected to the third driven wheel 311 and coaxially arranged. The brush 313 includes a plurality of brushes 313 spaced apart on the outer surface of the shaft body 312. The rotation of the third driven wheel 311 can drive the shaft body 312 to rotate, and the rotation of the shaft body 312 can drive the brush 313 to rotate, so that the brush 313 can clean the surface of the battery cell 1. The plurality of brushes 313 can increase the contact area between the first cleaning roller 31 and the battery cell 1, and thus improve the cleaning effect of the debris on the surface of the battery cell 1.

[0046] Preferably, the first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, and the fourth cleaning roller 34 have the same structure.

[0047] As Figure 2 and Figure 4 As shown, in this embodiment, the brush 313 is bent, and the angle between the tangent of the outer surface of the brush 313 and the horizontal plane is between 15° and 60°. The brush 313 is bent so that after the brush 313 contacts the battery cell 1, the debris on the surface of the battery cell 1 can be separated from the surface of the battery cell 1 under the action of the bent brush 313, avoiding the hair debris on the surface of the battery cell 1 leaking from the gaps between the plurality of brushes 313 and being unable to be cleaned by the brush. Then, under the action of the suction component 40, the debris can be sucked away. The angle between the tangent of the outer surface of the brush 313 and the horizontal plane is between 15° and 60°, so that after the debris on the surface of the battery cell 1 is removed by the brush, it can float more smoothly in the suction component 40 and then be sucked away by the suction component 40.

[0048] Preferably, in this embodiment, the brush 313 of the first cleaning roller 31 is bent away from the fifth bevel gear 3111, the brush 313 of the second cleaning roller 32 is bent away from the second bevel gear 3211, the brush 313 of the third cleaning roller 33 is bent towards the third bevel gear 3311, and the brush 313 of the fourth cleaning roller 34 is bent towards the sixth bevel gear 3411. The angle between the tangent of the outer surface of the brush 313 and the horizontal plane can be 15°, 30°, 45°, 50°, 55° or 65°. In this embodiment, the angle between the tangent of the outer surface of the brush 313 and the horizontal plane is 45°.

[0049] As Figure 1 and Figure 5 shown, in this embodiment, the suction component 40 includes an air extraction member and a cover 41. The cover 41 covers the outside of the frame 10, the drive component 20, the cleaning component 30 and the suction component 40, and the air extraction member is communicated with the top of the cover 41. Through the above settings, the air extraction member can not only suck floating impurities, but also suck the impurities adsorbed on the surface of the cleaning component 30, avoiding the decline of the cleaning effect caused by the large amount of impurities adsorbed on the surface of the cleaning component 30 after being used for a period of time. The air extraction member can extract the gas in the cover 41, so that the sundries on the surface of the battery cell 1 cleaned by the cleaning component 30 can move to the outside of the cover 41 through the top of the cover 41.

[0050] As Figure 2 and Figure 3As shown, in this embodiment, the frame 10 includes a main body 11, a first support column 12, a second support column 13, a third support column 14, and a fourth support column 15.

The third cleaning roller 33 is rotatably connected to the third support column 14. The fourth cleaning roller 34 is rotatably connected to the fourth support column 15. The main body 11 can support the first support column 12, the second support column 13, the third support column 14, and the fourth support column 15. The first support column 12 enables the first cleaning roller 31 to be connected to the main body 11. The second support column 13 enables the second cleaning roller 32 to be connected to the main body 11. The third support column 14 enables the third cleaning roller 33 to be connected to the main body. The fourth support column 15 enables the third cleaning roller 33 to be connected to the main body, so that the first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, and the fourth cleaning roller 34 can rotate stably. The first support column 12, the second support column 13, the third support column 14, and the fourth support column 15 extend along the height direction of the main body, so that the first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, and the fourth cleaning roller 34 can have a gap with the main body 11 in the height direction, facilitating the rotation of the first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, and the fourth cleaning roller 34, and thus facilitating the cleaning of the battery cell 1.

When the air extraction member is in use, the inside of the cover body 41 is evacuated, and the sundries are extracted and transported to the collection area through the vacuum. The application range is wide and is not affected by the shape of the sundries.

[0053] It should be noted that in an embodiment not shown in the figure, the cleaning assembly 30 may further include a fifth cleaning roller. The frame 10 further includes a ninth support pillar and a tenth support pillar that are connected to the main body 11 and are located below the main body 11, and the ninth support pillar and the tenth support pillar are arranged at intervals.

The first end of the fifth cleaning roller is rotatably connected to the ninth support pillar, and the second end of the fifth cleaning roller is rotatably connected to the tenth support pillar, so that the contact area between the cleaning assembly 30 and the battery cell 1 can be increased, ensuring the cleaning effect of the cleaning assembly 30. The driving assembly 20 further includes a third rotating member, a third rotating rod, and a third driving wheel provided on the third rotating rod. The third rotating rod is rotatably provided on the main body 11. A fifth driven wheel is provided on a side portion in the axial direction of the fifth cleaning roller. The battery cell cleaning device further includes a third transmission member. When the third rotating member rotates, it can drive the third transmission member to rotate. When the third transmission member rotates, it can drive the third rotating rod to rotate. When the third rotating rod rotates, it can drive the third driving wheel to rotate. When the third driving wheel rotates, it can drive the fifth driven wheel to rotate, and further drive the fifth cleaning roller to rotate.

[0054] The third rotating member is a third circular gear. The third driving wheel is a seventh bevel gear, and the fifth driven wheel is an eighth bevel gear. The cleaning assembly 30 includes at least one fifth cleaning roller. When there is one fifth cleaning roller, the outer shape of the main body 11 is a pentagon, and the first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, the fourth cleaning roller 34, and the fifth cleaning roller are respectively arranged at the five corners of the pentagon. When the cleaning assembly 30 includes a plurality of fifth cleaning rollers, the outer shape of the main body 11 is an n-sided polygon, where n is a positive integer greater than or equal to 2. The first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, the fourth cleaning roller 34, and the plurality of fifth cleaning rollers are respectively arranged at the n corners of the n-sided polygon. At this time, the number of fifth cleaning rollers is n - 4. Of course, the outer shape of the main body 11 can also be circular, or other shapes, and the first cleaning roller 31, the second cleaning roller 32, the third cleaning roller 33, the fourth cleaning roller 34, and the fifth cleaning roller are arranged at intervals on the outer periphery of the main body 11.

[0055] As Figures 1 to 5 shown, the battery cell production line of this embodiment includes a battery cell cleaning device and a conveying member. The battery cell cleaning device is the above-mentioned battery cell cleaning device. The conveying member is arranged below the cleaning assembly 30. The conveying member drives the battery cell 1 to pass below the cleaning assembly 30 so that the cleaning assembly 30 can clean the battery cell 1. After the cleaning assembly 30 of the above-mentioned battery cell cleaning device cleans the surface of the battery cell, under the action of the suction assembly 40, the sundries can be sucked away, preventing the sundries from floating in the external environment, and further preventing the sundries from falling onto the surface of the battery cell 1 again. The battery cell production line having the above-mentioned battery cell cleaning device also has the above-mentioned advantages.

[0056] It should be noted that when the conveying member conveys the battery cell 1, the battery cell 1 moves in the direction from the third cleaning roller 33 to the first cleaning roller 31 or in the direction from the first cleaning roller 31 to the third cleaning roller 33. The second cleaning roller 32 and the fourth cleaning roller 34 can clean the surface of the battery cell 1 close to the second cleaning roller 32 and the fourth cleaning roller 34. Of course, the battery cell 1 can also move in the direction from the second cleaning roller 32 to the fourth cleaning roller 34 or in the direction from the fourth cleaning roller 34 to the second cleaning roller 32, and the first cleaning roller 31 and the third cleaning roller 33 clean the surface of the battery cell 1 close to the first cleaning roller 31 and the third cleaning roller 33.

It is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0058] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation other than the orientation described in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will be positioned as "below other devices or structures" or "under other devices or structures" afterwards. Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations are made for the spatial relative descriptions used here.

[0059] In addition, it should be noted that the use of words such as "first", "second" to limit the components is only for the convenience of distinguishing the corresponding components.
