It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0022] The cleaning device provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0023] like Figures 1 to 5 As shown, an embodiment of the present application provides a cleaning device for cleaning the battery cell 400. Of course, the cleaning device can also be used to clean other structural parts, and the embodiment of the present application does not impose any specific restrictions on this. Optionally, the battery cell 400 in the present application can be a battery cell of a mobile phone battery or a battery cell of a tablet battery, and the embodiment of the present application does not impose any specific restrictions on this. Optionally, in the process of cleaning the battery cell 400, the battery cell 400 can be placed on the carrying platform 700 by a manipulator to facilitate cleaning by the cleaning device. Optionally, in the process of placing the battery cell 400 by the manipulator, it can be positioned by an image sensor to ensure that the battery cell 400 is accurately placed on the work station of the carrying platform 700.

[0024] The cleaning device includes a bracket 100, a brush 200, and a drive assembly 300. The drive assembly 300 is disposed on the bracket 100, and the brush 200 is connected to the drive assembly 300. The drive assembly 300 can drive the brush 200 to reciprocate along the surface of the battery cell 400 to clean impurities attached to the surface of the battery cell 400. The impurities here can be foreign matter such as white flocs and dust generated during the battery cell manufacturing process. Optionally, the brush 200 can be an elongated structure. In the length direction of the brush 200, the size of the brush 200 is greater than or equal to the size of the battery cell 400, thereby ensuring the cleaning efficiency of the brush 200. Optionally, the brush 200 includes a brush body 210, a mounting member 220, and a fastener 230. The brush body 210 is mounted to the mounting member 220 via the fastener 230, and the mounting member 220 is connected to the drive assembly 300.

[0025] In an embodiment of the present application, after the battery cell 400 is manufactured, before the blue film is applied, the battery cell 400 is placed on the carrier platform 700, and the driving assembly 300 of the cleaning device drives the brush 200 to reciprocate along the surface of the battery cell 400 to clean the impurities attached to the surface of the battery cell 400, thereby meeting the requirements for applying the blue film. This solution uses a cleaning device to clean impurities on the surface of the battery cell 400, eliminating the need for manual wiping, which can save costs; and, using the cleaning device for cleaning can be performed sequentially according to a set control program, with a high degree of automation. Compared with manual wiping, it can greatly reduce the risk of applying the blue film without wiping the battery cell. Therefore, the embodiment of the present application can solve the current problems of high cost of applying the blue film to the battery cell 400 and the risk of applying the blue film without wiping it.

[0026] In an optional embodiment, the cleaning device further includes a dust collection assembly 500, which includes a dust collection tube 510 and an air duct 520 that are connected to each other. Optionally, one end of the air duct 520 is connected to the dust collection tube 510, and the other end of the air duct 520 is connected to an exhaust device. The exhaust device is used to create a low-pressure environment in the air duct 520 and the dust collection tube 510 to absorb impurities on the surface of the battery cell 400. The low-pressure environment here specifically refers to the pressure in the air duct 520 and the dust collection tube 510 being lower than the ambient pressure. At least a portion of the air duct 520 is a deformable structure. Optionally, at least a portion of the air duct 520 can be a bellows, or of course, other types of hoses. This embodiment of the present application does not impose specific limitations on this. The suction tube 510 and the brush 200 are arranged side by side along the direction of the brush 200's movement and are fixed together. The suction port of the suction tube 510 faces the battery cell 400. The drive assembly 300, through the brush 200, drives the suction tube 510 to reciprocate along the surface of the battery cell 400. As the brush 200 reciprocates along the surface of the battery cell 400, friction is generated between the two, driving impurities on the surface of the battery cell 400. The suction tube 510 then draws these impurities into the suction assembly 500. This solution, by combining the suction assembly 500 with the brush 200, allows for simultaneous sweeping and suction, not only improving cleaning efficiency but also preventing secondary contamination. Of course, the suction assembly 500 can also be omitted; alternatively, when the suction assembly 500 is provided, the suction tube 510 and the brush 200 can be separate, meaning that the suction tube 510 is stationary and does not move with the brush 200.

[0027] In a further optional embodiment, the cleaning device further includes a protective cover 600, which is mounted on a supporting platform 700 for supporting the battery cell 400. The brush 200, the suction tube 510, and a portion of the drive assembly 300 are all located within the protective cover 600. When the protective cover 600 is mounted on the supporting platform 700, the protective cover 600 and the supporting surface of the supporting platform 700 form a confined space. In this case, the entire process of cleaning the battery cell 400 can be carried out within the confined space. This prevents impurities from being splashed around and contaminating other structures when the brush 200 is cleaning. Of course, the protective cover 600 can also be omitted.

[0028] Optionally, the protective cover 600 includes a detachably connected cover body 610 and a cover plate 620. When a robot is required to pick up or place the battery cell 400, the cover plate 620 can be opened to facilitate the passage of the robot. Optionally, the cover body 610 can be a metal structure, such as a steel structure, an aluminum alloy structure, etc., which is not specifically limited in this embodiment of the present application. Optionally, the cover plate 620 can be a transparent cover plate, which makes it easy to observe whether the battery cell 400 has been cleaned during the cleaning process; optionally, the cover plate 620 can be an acrylic structure, which has the characteristics of high transparency, strength and toughness.

[0029] In another optional embodiment, the cleaning device further includes a purge pipe, which is detachably mounted on the protective cover 600, and the brush 200 is located between the purge pipe and the dust suction pipe 510. The air outlet of the purge pipe faces the battery cell 400, and one end of the purge pipe passes through the protective cover 600 and is connected to the air source. In the process of the brush 200 cleaning the battery cell 400, the air outlet of the purge pipe blows gas toward the battery cell 400 to separate the fine impurities attached to the surface of the battery cell 400 from the battery cell 400 so that they can be sucked up by the dust suction pipe 510. In other words, this solution integrates blowing, sweeping, and suctioning, which is conducive to further improving the cleaning efficiency of the cleaning device. Of course, the purge pipe can also be set on the supporting platform 700, or the purge pipe may not be set.

[0030] Optionally, the purge tube can be detachably connected to the two opposite side walls of the protective cover 600, and in the direction perpendicular to the bearing surface of the bearing platform 700, the orthographic projection of the purge tube is staggered with the orthographic projection of the battery cell 400, thereby preventing the purge tube from affecting the cleaning range of the brush 200.

[0031] Optionally, the gas blown out by the above-mentioned purge tube may contain plasma. Specifically, the compressed air may be ionized into high-energy disordered plasma by high-frequency discharge and blown out, and then the plasma bombards the surface of the battery cell 400 to achieve the purpose of cleaning and activating impurities; or, the above-mentioned purge tube may utilize ultrasonic dust removal, specifically, a blower provides 8~16KPa of clean gas to the ultrasonic generating chamber of the purge tube, and the clean gas generates ultrasonic waves through an ultrasonic generator, and then utilizes the energy and vibration of ultrasonic propagation to eliminate the adhesion force on the surface of the battery cell 400, and separates the dust from the surface of the battery cell 400 by at least one of the three motion modes of pulling, rolling and sliding.

[0032] Alternatively, the dust suction tube 510 may be a tubular structure with a suction port formed on the tubular structure; or, in another optional embodiment, the dust suction tube 510 includes a tube body 511 and a dust guide portion 512 connected thereto, wherein the dust guide portion 512 is provided with a dust guide channel 512a and a suction port connected thereto, and the width of the dust guide channel 512a gradually decreases as the dust guide portion 512 extends toward the tube body 511. The width of the dust guide channel 512a herein specifically refers to the size of the dust guide channel 512a in the direction of movement of the brush 200, i.e., the dust guide channel 512a is a trumpet-shaped structure. A dust suction tube 510 employing this structure has a larger suction port, which facilitates the entry of impurities and simultaneously ensures a pressure difference between the inside and outside of the tube body 511, thereby improving the dust suction efficiency of the dust suction tube 510.

[0033] Optionally, the dust collection tube 510 and the brush 200 can be directly connected by bonding or the like; or, in other embodiments, the dust collection assembly 500 further includes a first connector 530, one end of which is connected to the dust collection tube 510, and the other end of the first connector 530 is detachably connected to the brush 200, so that the dust collection tube 510 is connected to the brush 200 through the first connector 530, which not only ensures that the dust collection tube 510 and the brush 200 are stably connected, but also facilitates the disassembly and assembly of the two.

[0034] Optionally, the first connecting member 530 and the brush 200 may be connected by connecting members such as screws, and this embodiment of the present application does not impose any specific limitation on this.

[0035] Optionally, the first connector 530 includes a first connecting portion 531 and a second connecting portion 532 connected to each other. The second connecting portion 532 is bent relative to the first connecting portion 531, i.e., the first connector 530 has an L-shaped structure. The first connecting portion 531 is sleeved onto the dust collection tube 510, and the second connecting portion 532 is detachably connected to the brush 200. The second connecting portion 532 is located between the dust collection tube 510 and the brush 200, i.e., the dust collection tube 510 and the brush 200 are spaced apart along the direction of movement of the brush 200. When the brush 200 reciprocates along the surface of the battery cell 400, the brush body 210 of the brush 200 will deform. By spacing the dust collection tube 510 and the brush 200 apart, interference between the two can be avoided. Of course, the first connector 530 can also have a linear structure.

[0036] In another optional embodiment, the air duct 520 includes a first tube section 521 and a second tube section 522 that are connected. The first tube section 521 is connected to the dust suction tube 510, and the second tube section 522 is a deformable structure. When the dust suction tube 510 reciprocates along the surface of the battery cell 400 along with the brush 200, the second tube section 522 deforms to meet the movement requirements of the dust suction tube 510. The dust suction assembly 500 also includes a second connecting member 540, which includes a third connecting portion 541 and a fourth connecting portion 542 that are connected. Optionally, the third connecting portion 541 and the fourth connecting portion 542 can be an integrated structure or a split structure, which is not specifically limited in this embodiment of the present application. The fourth connecting portion 542 is bent relative to the third connecting portion 541, meaning that the second connecting member 540 is L-shaped. The third connecting portion 541 is sleeved onto the first tube section 521. Optionally, the first tube section 521 can be rigid to provide a base for the third connecting portion 541. The fourth connecting portion 542 is detachably connected to the brush 200. This solution connects the air duct 520 and the brush 200 via the second connecting member 540, further improving the stability of the suction tube 510. Of course, the second connecting member 540 can also be a linear structure, or it can be omitted.

[0037] Optionally, the fourth connecting portion 542 can be an annular structure to reduce the weight of the second connecting member 540 and facilitate its detachable connection with the brush 200. Specifically, the inner ring surface of the annular structure is provided with a connecting hole, and one end of the connecting member passes through the connecting hole and is threadedly connected to the brush 200.

[0038] In an optional embodiment, the drive assembly 300 includes a first drive member 310, a second drive member 320 and a carrier 330. The first drive member 310 is arranged on the bracket 100, and the carrier 330 is connected to the output shaft of the first drive member 310. The second drive member 320 is arranged on the carrier 330, and the output shaft of the second drive member 320 is connected to the brush 200. The first drive member 310 can drive the carrier 330, the second drive member 320 and the brush 200 to rise and fall together, and the second drive member 320 can drive the brush 200 to reciprocate along the surface of the battery cell 400, that is, the second drive member 320 drives the brush 200 to reciprocate in the horizontal plane. This solution improves the movement flexibility of the brush 200 by providing multiple drive members to drive the brush 200 to move in different directions, so that the brush 200 can move to a suitable position to work, thereby improving the cleaning efficiency of the brush 200. Of course, the first driving member 310 may not be provided. In this case, the vertical positions of the brush 200 and the carrying platform 700 need to be precisely set to ensure that the brush 200 can clean impurities on the surface of the battery cell 400.

[0039] Alternatively, the output shaft of the second driving member 320 may be directly connected to the brush 200; or, in other optional embodiments, the driving assembly 300 further includes a sliding rail 340 and a slider 350 that slidably cooperate, wherein the sliding rail 340 is disposed on the carrier 330, the slider 350 is connected to the brush 200, and the slider 350 is disposed side by side with the second driving member 320. The slider 350 and the output shaft of the second driving member 320 are detachably connected, so that the output shaft of the second driving member 320 is connected to the brush 200 via the slider 350, and the sliding direction of the slider 350 is parallel to the extension and contraction direction of the output shaft of the second driving member 320. In this solution, when the second driving member 320 drives the brush 200 to move via the slider 350, the slider 350 and the sliding rail 340 slidably cooperate, resulting in a larger connection area between the two, which helps to improve the movement stability of the brush 200.

[0040] In another optional embodiment, the slider 350 has a connecting protrusion 351, which can be directly sleeved on the output shaft of the second driving member 320, and the two can be positioned and matched by friction; or, the connecting protrusion 351 is provided with a connecting opening 351a, which passes through the two opposite sides of the connecting protrusion 351, and the connecting protrusion 351 is sleeved on the output shaft of the second driving member 320 through the connecting opening 351a, and the output shaft of the second driving member 320 is provided with a first convex portion at intervals. The flange portion 321 and the second flange portion 322 are located on either side of the connecting protrusion 351 in the extension and contraction direction of the output shaft of the second driving member 320. The width of the first flange portion 321 and the width of the second flange portion 322 are both greater than the width of the connecting opening 351a. When the second driving member 320 drives the brush 200 to reciprocate along the surface of the battery cell 400, the first flange portion 321 or the second flange portion 322 abuts against the connecting protrusion 351. When the output shaft of the second driving member 320 is extended, the first flange portion 321 abuts against the first side surface of the connecting protrusion 351. When the output shaft of the second driving member 320 is retracted, the second flange portion 322 abuts against the second side surface of the connecting protrusion 351, thereby pushing the slider 350 to slide relative to the slide rail 340, thereby driving the brush 200 to reciprocate. The slider 350 in this solution is connected to the output shaft of the second driving member 320 in the above manner, which can facilitate the assembly and disassembly of the slider 350 and the second driving member 320 while ensuring the stable transmission of the driving force between the two.

[0041] Alternatively, the carrier 330 may be a carrier plate; or, in other embodiments, the carrier 330 includes a mounting plate 331 and a connecting plate 332 connected to the bracket 100. The connecting plate 332 is slidably connected to the bracket 100. Optionally, one of the connecting plate 332 and the bracket 100 may be provided with a guide groove 110, and the other may be provided with a sliding protrusion. The sliding protrusion slidably engages with the guide groove to enable the connecting plate 332 to be raised and lowered in a predetermined direction, thereby improving the movement accuracy of the brush 200. The mounting plate 331 is connected to the output shaft of the first driver 310. The first driver 310 can drive the connecting plate 332 to rise and fall relative to the bracket 100 via the mounting plate 331. The second driver 320 is disposed on the mounting plate 331. When the first driver 310 drives the mounting plate 331 to rise and fall, the connecting plate 332 slides relative to the bracket 100. That is, the carrier 330 is connected to the bracket 100 via the connecting plate 332. The connection area between the two is large, which helps to improve the connection stability of the carrier 330.

[0042] Optionally, the connecting plate 332 and the first driving member 310 can be respectively arranged on two opposite sides of the bracket 100, which can facilitate the arrangement of the two; and the connection area between the first driving member 310 and the bracket 100 is larger, which can improve the stability of the first driving member 310.

[0043] Optionally, at least one of the first driving member 310 and the second driving member 320 may be a cylinder, a hydraulic cylinder, etc., and this embodiment of the present application does not impose any specific limitation on this.

[0044] Based on the cleaning device provided in the embodiment of the present application, it uses a blowing, sweeping and suctioning method to blow away dust and other impurities attached to the surface of the battery cell 400. At the same time, the dust suction component 500 can be used to suck the blown impurities into the dust suction tube 510, thereby reducing the defective rate of blue film foreign matter, and the finished product defective rate of the battery cell 400 can be controlled below 0.2%.

[0045] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
