Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and particularly to a cleaning device and a battery production line. Background Art

[0002] During the process of core assembly, it is inevitable to generate some dust and other pollution particles. If these substances remain on the surface of the assembled core, it will not only pose a risk of short circuit between the cores, but also in the subsequent core assembly process, these dusts may fall off and migrate to other key parts, causing unnecessary pollution or potential faults. Therefore, cleaning the dust on the surface of the core is not only one of the basic guarantee measures for product performance and safety, but also an important step to improve production quality and extend the service life of the product.

[0003] Currently, the existing cores are mainly cleaned by blowing air or brushing on the surface. During this cleaning process, since the dust blown off or brushed off from the surface of the core cannot be effectively collected, the dust will spread into the surrounding space during the cleaning process, resulting in a decrease in the cleanliness of the space, and the dust in the space is likely to fall back onto the surface of the core again, thus resulting in an incomplete cleaning situation. Summary of the Invention

[0004] In view of this, the present invention provides a cleaning device and a battery production line to solve the problem of poor cleaning effect of the existing cleaning method for the surface of the core.

[0005] In a first aspect, the present invention provides a cleaning device having intersecting first and second directions. The cleaning device includes: a conveying unit, a cleaning unit, and a driving unit; the conveying unit has a conveying structure for driving the core to move in the first direction; the cleaning unit is arranged on one side of the moving path of the core along the second direction, and the cleaning unit has a dust - sticking rubber roller and a cleaning rubber roller that can both rotate. The cleaning rubber roller is arranged on one side in the radial direction of the dust - sticking rubber roller. The dust - sticking rubber roller has a first dust - sticking surface for cleaning the surface of the core, the cleaning rubber roller has a second dust - sticking surface, the first dust - sticking surface is in rolling contact with the second dust - sticking surface, and the viscosity of the first dust - sticking surface is lower than that of the second dust - sticking surface; the driving unit is respectively drivingly connected to the conveying structure and the dust - sticking rubber roller.

[0006] Beneficial effects: A cleaning unit is provided on one side of the moving path of the battery cell. When the battery cell passes by the dust sticking roller, the dust sticking roller rotates as the battery cell moves. Since the first dust sticking surface is sticky, the first dust sticking surface rolls along the surface of the battery cell, and thus the dust particles on the surface of the battery cell can be stuck to its own surface, thereby realizing the cleaning function. It can not only collect the dust particles and prevent the dust from spreading into the production space, but also avoid damaging the surface of the battery cell. In addition, the second dust sticking surface of the cleaning roller can also clean the first dust sticking surface, ensuring the cleaning reliability of the dust sticking roller, so that the cleaning device of this embodiment has the characteristics of stable and reliable cleaning effect and high efficiency, effectively solving the problem of poor cleaning effect of the existing cleaning method for the surface of the battery cell.

[0007] In an optional embodiment, the conveying unit includes a carrier frame, and a conveying structure is arranged on the carrier frame. The conveying structure includes a conveyor belt and a conveying shaft. The conveying shaft is rotatably arranged on the carrier frame, and the conveying shaft is in transmission cooperation with the conveyor belt; the cleaning unit includes a mounting frame connected to the carrier frame, and a dust sticking roller and a cleaning roller are both rotatably arranged on the mounting frame; the driving unit is connected to the carrier frame and has a driving shaft, and the driving shaft is in transmission cooperation with the conveying shaft and the dust sticking roller respectively, and the driving shaft drives the conveying shaft and the dust sticking roller to rotate simultaneously.

[0008] Beneficial effects: Through this driving cooperation form, only one driving unit can drive the conveying shaft and the dust sticking roller to rotate simultaneously. The overall structure is simple and reliable and can be arranged more compactly. It can effectively reduce the number of components of the driving unit and reduce the complexity of the cleaning device.

[0009] In an optional embodiment, the cleaning device further has a third direction intersecting with the first direction and the second direction. The driving shaft drives the conveying shaft and the dust sticking roller to rotate simultaneously; the driving shaft extends along the third direction, and a first driving wheel and a second driving wheel are fixedly arranged on the driving shaft; the conveying shaft extends along the third direction, and a first matching wheel is fixedly arranged on the conveying shaft. The first driving wheel is in transmission cooperation with the first matching wheel through a first transmission belt; one end of the dust sticking roller is fixedly provided with a second matching wheel, and a third matching wheel is rotatably arranged on the mounting frame. The third matching wheel is located on one side of the radial direction of the second matching wheel. The second driving wheel is in transmission cooperation with the third matching wheel through a second transmission belt, and the second matching wheel is in transmission cooperation with the outer side of the second transmission belt.

[0010] Beneficial effects: Using this transmission form, the driving shaft drives the conveying shaft and the dust sticking roller to rotate in opposite directions, so that when the dust sticking roller contacts the battery cell, the rotation direction of its contact surface matches the moving direction of the battery cell, avoiding the situation that the dust sticking roller hinders the movement of the battery cell. In addition, the transmission through the transmission belt can increase the length of the transmission path and effectively improve the flexibility of the installation position of the driving unit.

[0011] In an alternative embodiment, the conveying speed of the conveyor belt is consistent with the linear speed of the first dust sticking surface.

[0012] Beneficial effects: Through this setting form, the situation of the battery core rubbing against the side wall surfaces on both sides in the second direction can be effectively reduced, so that the battery core can pass stably between the dust sticking rubber roller and the conveyor belt.

[0014] The mounting frame includes two mounting seats arranged at intervals in the third direction. Mounting grooves are provided on the opposite wall surfaces of the two mounting seats. The openings of the mounting grooves face the third direction and extend along the second direction. On the side of the mounting groove away from the dust sticking rubber roller in the second direction, there is a mounting opening, and both ends of the cleaning rubber roller enter the mounting groove through the mounting openings respectively.

[0015] Beneficial effects: The split mounting frame occupies less space and is convenient for installation and manufacturing; along the second direction, the cleaning rubber roller can be conveniently and quickly installed into or taken out of the mounting groove through the mounting opening. This assembly form is more convenient for disassembling and assembling the cleaning rubber roller.

[0016] In an alternative embodiment, the cleaning rubber roller includes a first rotating shaft, a limiting structure and a cleaning paper roll. The first rotating shaft extends along the second direction, and the end is used for plugging and matching with the mounting groove. The cleaning paper roll is rotatably sleeved outside the first rotating shaft. Limiting structures are provided on both sides of the cleaning paper roll along the second direction, and the limiting structures are detachably connected to the first rotating shaft.

[0017] Beneficial effects: Since the sizes of the battery cores are various, by using the cleaning rubber roller in this form, after unlocking and removing the limiting structure, the cleaning paper roll of the corresponding size can be replaced. This not only makes the cleaning rubber roller have stronger adaptability, but also when the cleaning rubber roller needs to be maintained, it is not necessary to replace the whole cleaning rubber roller, and only the cleaning paper roll needs to be replaced.

[0018] In an alternative embodiment, the first rotating shaft includes a first shaft section and a second shaft section arranged coaxially. The first shaft section has a first plugging structure, and the second shaft section has a second plugging structure. The first plugging structure and the second plugging structure are plugged and matched.

[0019] Beneficial effects: With the first shaft section and the second shaft section in this form, the first rotating shaft can achieve the quick-release function.

[0020] In an optional embodiment, the limiting structure includes a limiting ring and a locking piece, the limiting ring has a through groove opening toward the outer peripheral surface, a portion of the through groove forms a through hole for the first rotating shaft to pass through, the limiting ring forms locking ends at both ends of the through groove opening, the locking piece passes through the two locking ends, and the two locking ends are tied and fixed.

[0021] Beneficial effects: The limiting structure is simple and reliable, easy to process and manufacture, and the limiting structure can be fixedly connected to the first rotating shaft by clamping. This form of limiting structure can directly lock its own position with the outer wall of the first rotating shaft, so it can also flexibly adjust its own position, which is convenient for adapting to cleaning paper rolls of various sizes.

[0022] In an optional embodiment, the mounting seat includes a main body, a first mounting structure and a second mounting structure, the first mounting structure and the second mounting structure are respectively detachably connected to the main body, the first mounting structure has a first connection position, the first connection position is used to assemble and connect with the end of the dust-sticky rubber roller, and the second mounting structure has a mounting groove; and / or, the mounting seat is detachably connected to the supporting frame through a fastening component, and the mounting seat is provided with a plurality of strip holes extending along the second direction, and the strip holes are used for the fastening components to pass through.

[0023] Beneficial effect: The mounting seat is a split structure. Since the sizes of battery cells 4 of different specifications along the second direction are different, this type of mounting seat can flexibly change the positions of the sticky rubber roller and the cleaning rubber roller by adjusting the positions of the first mounting structure and the second mounting structure. In addition, this type of mounting seat can flexibly adjust the positions of the sticky rubber roller and the cleaning rubber roller by adjusting its own position on the supporting frame.

[0046] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0047] In the related art, when using blowing to clean, the surface of the battery cell can be kept clean under the current blowing state, but during the subsequent movement of the battery cell, the dust particles blown into the environment will still fall back onto the surface of the battery cell; when using a brush to sweep and clean, when the brush is soft, it is difficult to effectively clean, and when the brush is hard, it is easy to damage the surface of the battery cell, and the cleaning effect is poor in both cases.

[0048] The following combines Figures 1 to 7 , to describe the embodiments of the present invention.

[0049] According to an embodiment of the present invention, on the one hand, a cleaning device is provided, having intersecting first direction X and second direction Y. The cleaning device includes: a conveying unit 1, a cleaning unit 2, and a driving unit 3;

[0050] The conveying unit 1 has a conveying structure 101, and the conveying structure 101 is used to drive the battery cell 4 to move in the first direction X;

[0051] The cleaning unit 2 is arranged on one side of the moving path of the battery cell 4 along the second direction Y. The cleaning unit 2 has a rotatable dust-removing rubber roller 201 and a cleaning rubber roller 202. The cleaning rubber roller 202 is arranged on one side in the radial direction of the dust-removing rubber roller 201. The dust-removing rubber roller 201 has a first dust-removing surface 2011 for cleaning the surface of the battery cell 4. The cleaning rubber roller 202 has a second dust-removing surface 2021. The first dust-removing surface 2011 is in rolling contact with the second dust-removing surface 2021, and the adhesiveness of the first dust-removing surface 2011 is lower than that of the second dust-removing surface 2021;

[0052] The driving unit 3 is respectively drivingly connected to the conveying structure 101 and the dust sticking roller 201.

[0053] When applying the cleaning device of this embodiment, a cleaning unit 2 is arranged on one side of the moving path of the battery cell 4. When the battery cell 4 passes by the dust sticking roller 201, the dust sticking roller 201 rotates as the battery cell 4 moves. Since the first dust sticking surface 2011 has adhesiveness, the first dust sticking surface 2011 rolls along the surface of the battery cell 4, and thus the dust particles on the surface of the battery cell 4 can be adhered to its own surface, thereby realizing the cleaning function. It can not only collect the dust particles to prevent the dust from spreading into the production space, but also avoid damaging the surface of the battery cell 4. In addition, the second dust sticking surface 2021 of the cleaning roller 202 can also clean the first dust sticking surface 2011 to ensure the cleaning reliability of the dust sticking roller 201, so that the cleaning device of this embodiment has the characteristics of stable and reliable cleaning effect and high efficiency, effectively solving the problem of poor cleaning effect of the existing cleaning method for the surface of the battery cell.

[0054] Among them, it should be noted that the first direction X refers to Figure 1 the direction of "X" pointed by the arrow in Figure 1 ; the second direction Y refers to Figure 1 the direction of "Y" pointed by the arrow in, which is parallel to the direction of gravity; the third direction Z refers to

[0055] In addition, it should be noted that the dust sticking roller 201 and the cleaning roller 202 that can both rotate can refer to that part of the dust sticking roller 201 and the cleaning roller 202 can rotate, or it can refer to that the dust sticking roller 201 and the cleaning roller 202 as a whole can rotate, and the specific rotatable form can be flexibly selected.

[0056] Specifically, the specific conveying form of the conveying unit 1 is not limited. It can be the form of conveying the battery cell 4 through a circulating conveyor belt, or it can be the conveying form of driving a push rod by a telescopic cylinder to push the battery cell 4 to move. Since there are many conveying methods and types that can drive the battery cell 4 to move, no more details will be described here, and it can be selected according to actual production.

[0057] Furthermore, the specific form of the cleaning roller 202 is not limited. It can be a cleaning paper roll with a peelable surface, or a roller similar to the dust sticking roller 201. When there are more dust particles on the second dust sticking surface 2021, as long as it can be cleaned and updated.

[0058] In a possible implementation manner, such as Figure 1As shown in the figure, the conveying unit 1 includes a carrier 102, and a conveying structure 101 is disposed on the carrier 102. The conveying structure 101 includes a conveyor belt 1011 and a conveying shaft 1012. The conveying shaft 1012 is rotatably disposed on the carrier 102, and the conveying shaft 1012 is in driving cooperation with the conveyor belt 1011; the cleaning unit 2 includes a mounting frame 203 connected to the carrier 102, and a dust sticking rubber roller 201 and a cleaning rubber roller 202 are rotatably disposed on the mounting frame 203; the driving unit 3 is connected to the carrier 102 and has a driving shaft 301. The driving shaft 301 is in driving cooperation with the conveying shaft 1012 and the dust sticking rubber roller 201 respectively. The driving shaft 301 drives the conveying shaft 1012 and the dust sticking rubber roller 201 to rotate simultaneously. Through this driving cooperation form, only one driving unit 3 can drive the conveying shaft 1012 and the dust sticking rubber roller 201 to rotate simultaneously. The overall structure is simple and reliable and can be arranged more compactly, which can effectively reduce the number of components of the driving unit 3 and reduce the complexity of the cleaning device.

[0059] Specifically, the structural form of the mounting frame 203 is not limited. It can be an integral frame structure or a split seat body, and can be flexibly selected.

[0060] In addition, the specific cooperation form of the driving shaft 301 with the conveying shaft 1012 and the dust sticking rubber roller 201 respectively is not limited. It can be to transmit power through transmission gears, or to transmit power through the form of cooperation of transmission gears and transmission belts, or to transmit power through the form of cooperation of transmission gears and transmission chains.

[0061] In a possible implementation manner, as Figure 1 shown, the cleaning device further has a third direction Z intersecting the first direction X and the second direction Y respectively. The driving shaft 301 drives the conveying shaft 1012 and the dust sticking rubber roller 201 to rotate simultaneously; the driving shaft 301 extends along the third direction Z, and a first driving wheel 302 and a second driving wheel 303 are fixedly arranged on the driving shaft 301; the conveying shaft 1012 extends along the third direction Z, and a first mating wheel 103 is fixedly arranged on the conveying shaft 1012. The first driving wheel 302 is in driving cooperation with the first mating wheel 103 through a first transmission belt 304; one end of the dust sticking rubber roller 201 is fixedly provided with a second mating wheel 204, and a third mating wheel 205 is rotatably arranged on the mounting frame 203. The third mating wheel 205 is located on one side in the radial direction of the second mating wheel 204. The second driving wheel 303 is in driving cooperation with the third mating wheel 205 through a second transmission belt 305, and the second mating wheel 204 is in driving cooperation with the outer side of the second transmission belt 305.

[0062] Using this transmission form, the drive shaft 301 drives the conveyor shaft 1012 and the dust-removing adhesive roller 201 to rotate in opposite directions, so that when the dust-removing adhesive roller 201 contacts the battery cell 4, the rotation direction of its contact surface matches the moving direction of the battery cell 4, avoiding the situation that the dust-removing adhesive roller 201 hinders the movement of the battery cell 4. In addition, transmission through the transmission belt can increase the length of the transmission path, effectively improving the flexibility of the installation position of the drive unit 3.

[0063] Among them, as Figure 1 shown, the second drive wheel 303 is in transmission cooperation with the third mating wheel 205 through the second transmission belt 305, which means that both the second drive wheel 303 and the third mating wheel 205 are located inside the second transmission belt 305.

[0064] Specifically, as Figure 1 shown, the third mating wheel 205 is a mating wheel independently arranged on the mounting bracket 203. A rotating shaft is provided on the wall surface of the mounting bracket 203, and the third mating wheel 205 is arranged on the rotating shaft through rotating parts such as bearings.

[0065] Furthermore, since the drive shaft 301 of this embodiment drives the conveyor shaft 1012 and the dust-removing adhesive roller 201 to rotate simultaneously, if the third mating wheel 205 is not provided, the conveyor shaft 1012 and the dust-removing adhesive roller 201 will rotate in the same direction. At this time, the dust-removing adhesive roller 201 will hinder the movement of the battery cell 4, easily causing relative movement between the battery cell 4 and the conveyor belt 1011, and then wearing the battery cell 4. The transmission form of this embodiment solves this problem.

[0066] In a possible implementation manner, the conveying speed of the conveyor belt 1011 is consistent with the linear speed of the first dust-removing surface 2011. Through this setting form, the situation of friction on both side walls of the battery cell 4 along the second direction Y can be effectively reduced, enabling the battery cell 4 to pass stably between the dust-removing adhesive roller 201 and the conveyor belt 1011.

[0067] Specifically, as Figure 1 and Figure 2 shown, in order to make the conveying speed of the conveyor belt 1011 consistent with the linear speed of the first dust-removing surface 2011, the first drive wheel 302 and the second drive wheel 303 with the same transmission radius can be used, and the first mating wheel 103 and the second mating wheel 204 with the same transmission radius can be used. At the same time, it is also necessary to make the conveying radius of the conveyor shaft 1012 consistent with the radius where the first dust-removing surface 2011 is located.

[0068] As an alternative implementation manner, it is not necessary to set according to the above radius requirements, and the radius relationship can also be flexibly changed according to needs, as long as the conveying speed of the conveyor belt 1011 can ultimately be made consistent with the linear speed of the first dust-removing surface 2011.

[0069] In a possible implementation, as Figures 2 to 4 shown, the cleaning device further has a third direction Z that intersects the first direction X and the second direction Y respectively;

[0070] The mounting bracket 203 includes two mounting seats 2031 spaced along the third direction Z. Mounting grooves 2032 are provided on the opposite wall surfaces of the two mounting seats 2031. The openings of the mounting grooves 2032 face the third direction Z and extend along the second direction Y. On the side of the mounting groove 2032 away from the dust sticking roller 201 in the second direction Y, there is a mounting opening 2033. Both ends of the cleaning roller 202 enter the mounting groove 2032 through the mounting openings 2033 respectively. The split-type mounting bracket 203 occupies a small space and is convenient for installation and manufacturing; along the second direction Y, the cleaning roller 202 can be conveniently and quickly loaded into or taken out of the mounting groove 2032 through the mounting opening 2033. This assembly form is more convenient for disassembling and assembling the cleaning roller 202.

[0071] In addition, the mounting groove 2032 can also play a guiding role. Since the mounting groove 2032 extends along the second direction Y, after the cleaning roller 202 is installed, the cleaning roller 202 can continuously contact the wall surface of the dust sticking roller 201 under its own gravity. When there are large particles on the surface of the dust sticking roller 201, when the cleaning roller 202 passes through the position where the large particles are located, it can move in the mounting groove 2032 in the direction away from the dust sticking roller 201, avoiding the situation that the cleaning roller 202 and the dust sticking roller 201 excessively squeeze the large particles and the large particles damage the surfaces of the cleaning roller 202 and the dust sticking roller 201.

[0072] Specifically, the specific dimensions of the mounting groove 2032 are not limited and can be flexibly matched according to the dimensions of the cleaning roller 202.

[0073] In a possible implementation, as Figure 3 and Figure 4 shown, the cleaning roller 202 includes a first rotating shaft 2022, a limiting structure 2023 and a cleaning paper roll 2024. The first rotating shaft 2022 extends along the second direction Y, and the end is used for plugging and matching with the mounting groove 2032. The cleaning paper roll 2024 is rotatably sleeved outside the first rotating shaft 2022. Limiting structures 2023 are provided on both sides of the cleaning paper roll 2024 along the second direction Y. The limiting structure 2023 is detachably connected to the first rotating shaft 2022. Since the sizes of the battery cells 4 are diverse, using the cleaning roller 202 in this form, after unlocking and removing the limiting structure 2023, the cleaning paper roll 2024 of the corresponding size can be replaced. This not only makes the adaptability of the cleaning roller 202 stronger, but also when the cleaning roller 202 needs maintenance, it is not necessary to replace the entire cleaning roller 202, and only the cleaning paper roll 2024 needs to be replaced.

[0074] Specifically, as Figure 3 and Figure 4 shown, in order to make the cleaning paper roll 2024 rotate more smoothly on the first rotating shaft 2022, the cleaning rubber roller 202 further includes a pair of rotating seats 2025 arranged in pairs. The rotating seats 2025 are sleeved outside the first rotating shaft 2022. The outer ring of the rotating seat 2025 is connected to the outer wall of the first rotating shaft 2022 through a bearing structure. The outer ring of the rotating seat 2025 has a supporting surface for supporting the inner wall of the cleaning paper roll 2024. Since the axial dimension of the cleaning paper roll 2024 may change, the pair of rotatable and movable rotating seats 2025 can be more flexibly adapted to cleaning paper rolls 2024 of various sizes.

[0075] Furthermore, as Figure 3 and Figure 4 shown, the end of the first rotating shaft 2022 that cooperates with the installation groove 2032 is a cooperation section. Cooperation surfaces 20225 are formed on both side wall surfaces of the cooperation section corresponding to the installation groove 2032. The cooperation surfaces 20225 are flat surfaces. After the first rotating shaft 2022 of this form cooperates with the installation groove 2032, it is difficult to rotate under the action of its own structure, and the first rotating shaft 2022 can be made more stable and reliable.

[0076] In addition, as Figure 1 shown, the dust sticking rubber roller 201 includes a dust sticking rubber roll 2012 and a second rotating shaft 2013. The dust sticking rubber roll 2012 is fixedly sleeved outside the second rotating shaft 2013. The second cooperation wheel 204 is fixedly arranged at the end of the second rotating shaft 2013. Since the dust sticking rubber roller 201 cannot permanently maintain its cleaning ability and also needs to be regularly inspected, maintained or replaced, therefore, for the dust sticking rubber roller 201 of this form, only the dust sticking rubber roll 2012 outside the second rotating shaft 2013 needs to be replaced, and there is no need to replace the entire dust sticking rubber roller 201.

[0077] In a possible implementation manner, as Figure 4 and Figure 5As shown in the figure, the first rotating shaft 2022 includes a first shaft section 20221 and a second shaft section 20222 arranged coaxially. The first shaft section 20221 has a first plugging structure 20223, and the first shaft section 20221 has a second plugging structure 20224. The first plugging structure 20223 and the second plugging structure 20224 are in plugging fit. In this form of the first shaft section 20221 and the second shaft section 20222, the first rotating shaft 2022 can achieve the quick-release function. When it is necessary to replace the cleaning paper roll 2024 of the same size, the cleaning rubber roller 202 as a whole is taken out from the installation groove 2032. At this time, the first shaft section 20221 and the second shaft section 20222 are pulled in opposite directions, and the first shaft section 20221 and the second shaft section 20222 can be pulled out from the cleaning paper roll 2024. Then, the first shaft section 20221 and the second shaft section 20222 are inserted into a new cleaning paper roll 2024, and after the two are in plugging fit, the replacement process of the cleaning paper roll 2024 can be completed without disassembling the limiting structure 2023, which can significantly improve the convenience and efficiency of the replacement process of the cleaning paper roll 2024.

[0078] Specifically, in this form of the first shaft section 20221 and the second shaft section 20222, when replacing the cleaning paper roll 2024, it is also not necessary to disassemble the rotating seat 2025.

[0079] Furthermore, as Figure 5 shown, the first plugging structure 20223 and the second plugging structure 20224 are multi-claw structures with the same structure. The first plugging structure 20223 and the second plugging structure 20224 can achieve the effect of rotating together by misaligned plugging. Among them, the number and size of the plugging claws of a single plugging structure are not limited, as long as the first plugging structure 20223 and the second plugging structure 20224 are firmly reliable after plugging and can rotate together.

[0080] It can be understood that as an alternative implementation manner, the first plugging structure 20223 and the second plugging structure 20224 can also be: one of them is a plugging hole, and the other is a plugging column. The plugging hole and the plugging column are structures with edges, and the effect of rotating together after plugging can also be achieved.

[0081] In a possible implementation manner, as Figure 4 and Figure 6As shown, the limiting structure 2023 includes a limiting ring 20231 and a locking piece 20232. The limiting ring 20231 has a through groove 20233 opening toward the outer peripheral surface. A part of the through groove 20233 forms a through hole 20234 for the first rotating shaft 2022 to pass through. The limiting ring 20231 forms locking ends 20235 at both ends of the opening of the through groove 20233. The locking piece 20232 passes through the two locking ends 20235 and fastens the two locking ends 20235. The limiting structure 2023 is simple and reliable in form and easy to process and manufacture. The limiting structure 2023 can be fixedly connected to the first rotating shaft 2022 by clamping. This form of limiting structure 2023 can directly lock its own position with the outer wall of the first rotating shaft 2022, so that it can also flexibly adjust its own position, which is convenient for adapting to cleaning paper rolls 2024 of various sizes.

[0082] Specifically, the two locking ends 20235 are respectively provided with locking holes 20236 for the locking member 20232 to pass through, the locking member 20232 is a bolt, and the inner wall of at least one locking hole 20236 is provided with an internal thread.

[0083] In a possible implementation, Figure 1 and Figure 2 As shown, the mounting seat 2031 includes a main body 20311, a first mounting structure 20312 and a second mounting structure 20313. The first mounting structure 20312 and the second mounting structure 20313 are respectively detachably connected to the main body 20311. The first mounting structure 20312 has a first connection position, which is used to assemble and connect with the end of the sticky rubber roller 201. The second mounting structure 20313 has a mounting groove 2032. The mounting seat 2031 is a split structure. Since the sizes of battery cells 4 of different specifications along the second direction Y are different, this form of mounting seat 2031 can flexibly change the positions of the sticky rubber roller 201 and the cleaning rubber roller 202 by adjusting the positions of the first mounting structure 20312 and the second mounting structure 20313, thereby effectively adapting to the battery cell 4 to avoid excessive downward pressure on the battery cell 4 and causing damage to the battery cell 4.

[0084] In a possible implementation, Figure 1 As shown, the mounting seat 2031 is detachably connected to the supporting frame 102 through a fastening component. The mounting seat 2031 is provided with a plurality of strip holes 2034 extending along the second direction Y. The strip holes 2034 are used for the fastening components to pass through. Since the sizes of battery cells 4 of different specifications along the second direction Y are different, this form of mounting seat 2031 can flexibly adjust the positions of the dust-sticking rubber roller 201 and the cleaning rubber roller 202 by adjusting its own position on the supporting frame 102, and can flexibly adapt to battery cells 4 of various specifications to avoid excessive downward pressure on the battery cells 4 and damage to the battery cells 4.

[0085] According to an embodiment of the present invention, on the other hand, a battery production line is provided, which includes: the above-mentioned cleaning device and moving device. The cleaning device is used to clean the surface of the battery cell 4, and the moving device has an accommodation space for accommodating the battery cell 4, and the moving device is used to move the battery to the conveying structure 101 of the cleaning device.

[0086] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
