[0026] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1:

[0029] Please see the attached Figure 1 and Figure 2 The battery cell end face cleaning device of the present invention includes a positioning mechanism 1 for fixing the battery cell 4. A cleaning mechanism 2 for cleaning the end face of the battery cell 4 is provided on one side of the positioning mechanism 1, which can clean dust or impurities adhering to the surface of the workpiece, especially the end face of the cylindrical battery cell 4.

[0030] Please see the attached Figure 1, wherein the positioning mechanism 1 includes a mounting seat 24, on which a support plate 11 for supporting the battery cell 4 is provided. The support plate 11 is specifically a vertically arranged long plate. As shown in some specific embodiments, a plurality of support plates 11 are provided, and the plurality of support plates 11 are spaced apart along the axial direction of the battery cell 4. Supporting the battery cell 4 by the plurality of support plates 11 can improve the stability of the battery cell 4 when cleaning.

[0031] Please combine Figure 2 A bracket 12 for placing the battery cell 4 is provided on the support plate 11. In a preferred embodiment, the bracket 12 is adapted to the support plate 11, which helps the support plate 11 to limit the horizontal movement of the battery cell 4 at the bracket 12 during the cleaning process. Specifically, the bracket 12 can be a U-shaped groove. It can be understood that this is not a specific limitation on the shape of the bracket 12, and technicians in related fields can make a choice according to the shape of the battery cell 4.

[0032] A fixing assembly 13 is provided on one side of the bracket 12 . Specifically, the fixing assembly 13 is provided above the support plate 11 to cooperate with the support plate 11 to fix the battery cell 4 to be cleaned in the bracket 12 .

[0033] A cleaning mechanism 2 is provided on one side of the support plate 11. The cleaning mechanism 2 is arranged corresponding to the end face of the battery cell 4 to be cleaned. The cleaning mechanism 2 includes a roller brush 21 for cleaning the end face of the battery cell 4. Specifically, the roller brush 21 is preferably, but not limited to, a circular roller brush 21. The circular roller brush 21 can be adapted to the cylindrical battery cell 4 to flexibly clean the end face of the battery cell 4, thereby ensuring the cleanliness of the battery cell 4 after cleaning. In other specific embodiments, the cross-section of the roller brush 21 can be larger than the end face of the battery cell 4 to fully clean the end face of the battery cell 4. This is not a specific limitation on the size of the roller brush 21, and the operator can adjust it according to actual conditions. The roller brush 21 is connected to a rotating drive member 22 for driving the roller brush 21 to rotate to clean the end face of the battery cell 4. In some specific embodiments shown, the rotating drive member 22 is preferably, but not limited to, a rotary motor. The output end of the rotary motor is connected to the handle of the roller brush 21 to achieve automatic cleaning of the end face of the battery cell 4. In other specific embodiments, a transmission seat may be provided between the roller brush 21 and the rotating drive member 22, and a bearing is passed through the transmission seat. The handle of the roller brush 21 is rotatably connected to the transmission seat in the bearing and is transmission-connected to the output end of the rotating drive member 22. The setting of the transmission seat and the bearing can improve the rotation stability of the roller brush 21.

[0034] When cleaning the end faces of the battery cell 4, the battery cell 4 is placed in the bracket 12, the fixing assembly 13 secures the battery cell 4, and the rotary drive member 22 drives the roller brush 21 to rotate to clean the end face of the corresponding side of the battery cell 4. The roller brush 21 cleans the metal dust or other impurities adhering to the end face of the battery cell 4 to ensure the cleanliness of the battery cell 4 before liquid injection and packaging, thereby solving the problem of dust or impurity adhesion causing short circuits in the battery cell 4. The roller brush 21 easily moves the battery cell 4 during cleaning, and the fixing assembly 13 positions the battery cell 4, ensuring the stability of the battery cell 4 during cleaning, and the battery cell 4 is less likely to be damaged during the cleaning process.

[0035] Example 2:

[0036] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the fixing component 13 of the utility model. Figure 2 and Figure 3 .

[0037] See Figure 2 The fixing assembly 13 of this embodiment includes a pressing block 131 for pressing the surface of the battery cell 4. In a preferred embodiment, the pressing block 131 can be an elastic soft block, such as a PU block. In other specific embodiments, the pressing block 131 can also be a rubber block, a silicone block, etc. The pressing block 131 has a certain degree of deformation ability, which can limit the movement of the battery cell 4 when pressing and fixing the battery cell 4. Even if the battery cell 4 is still able to remain stationary relative to the support plate 11 during the cleaning process, the pressing block 131 is made of a relatively soft material, which helps to reduce the possibility of the battery cell 4 being deformed and damaged when the pressing block 131 presses the battery cell 4.

[0038] Furthermore, a connecting seat 133 is provided on one side of the pressing block 131, and the connecting seat 133 is detachably connected to the pressing block 131. Specifically, the connecting seat 133 can be assembled with the pressing block 131 by bolts, so as to facilitate the replacement of the pressing block 131 that is damaged after being used for a period of time.

[0039] The connecting seat 133 is transmission-connected to a positioning drive member 132. As shown in some specific embodiments, the positioning drive member 132 is preferably but not limited to a positioning cylinder. The output end of the positioning cylinder is transmission-connected to the connecting seat 133. When the positioning drive member 132 drives the connecting seat 133 to approach the support plate 11, the connecting seat 133 drives the pressure block 131 to press down the battery cell 4 to be cleaned so that the battery cell 4 is fixed in the bracket 12.

[0040] See Figure 3In a preferred embodiment, the inner wall of the bracket 12 is provided with a protective layer 121 for protecting the battery cell 4. Specifically, the protective layer 121 is preferably, but not limited to, a polyurethane layer. In other specific embodiments, the protective layer 121 may also be a rubber layer. The protective layer 121 can increase friction with the surface of the battery cell 4 to limit the movement of the battery cell 4 during the cleaning process, while also protecting the battery cell 4 and buffering the pressure exerted by the pressing block 131 when pressing and fixing the battery cell 4. Specifically, the protective layer 121 can be detachably connected to the support plate 11, such as by bolts, to facilitate timely replacement of the protective layer 121.

[0041] Example 3:

[0042] The difference between this embodiment and the above embodiment is that this embodiment further optimizes the structure of the cleaning mechanism 2 of the utility model. Figure 4 .

[0043] The cleaning mechanism 2 of this embodiment further includes a movable seat 23 , on which the roller brush 21 is rotatably disposed, and the movable seat 23 is slidably disposed on one side of the mounting seat 24 .

[0044] The movable base 23 is in transmission connection with a movable member 231 for driving the movable base 23 to move horizontally toward or away from the pallet 11. Specifically, the movable member 231 is preferably, but not limited to, a movable cylinder. The output end of the movable cylinder is in transmission connection with the movable base 23. When the stroke of the movable cylinder changes, the movable base 23 is driven to move, thereby moving the roller brush 21 toward or away from the pallet 11 to clean the end face of the battery cell 4 or away from the pallet 11 to avoid the travel space. The movable member 231 can be disposed on the mounting base 24, and the rotary drive member 22 is disposed on the movable member 231. The cleaning mechanism 2 has a simple and compact structure, which can effectively save space.

[0045] The cleaning mechanism 2 also includes a dust collecting assembly 3, which is located between the support plate 11 and the roller brush 21 to collect dust or other impurities brushed off by the roller brush 21. In a preferred embodiment, the dust collecting assembly 3 includes a dust collecting box 31, which is arranged on one side of the support plate 11 and can be detachably connected to the mounting seat 24. The dust collecting box 31 is specifically a lidless box body to receive metal powder or other impurities brushed off by the roller brush 21. A dust removal port 311 is provided in the dust collecting box 31, and the dust collecting box 31 is connected to a dust collecting pipe 32 at the dust removal port 311. The dust collecting pipe 32 is specifically a vertically arranged pipe. As shown in some specific embodiments, the dust collecting pipe 32 is arranged at the bottom of the roller brush 21. The dust collecting pipe 32 is connected to a suction device, which can promptly suck out the fallen dust and impurities through the dust collecting pipe 32.

[0046] In a preferred embodiment, the outer cover of the roller brush 21 is provided with a housing 33. The roller brush 21 slides within the housing 33 and cleans the end faces of the battery cells 4 within the housing 33. The housing 33 prevents the spread of dust and other impurities, reducing the possibility of dust and impurities contaminating the working environment. The provision of the dust collection assembly 3 facilitates the centralized collection of dust and impurities removed by the roller brush 21. The compact structure and convenient operation enhance the practicality of the battery cell end face cleaning device.

[0047] In a preferred embodiment, two groups of cleaning mechanisms 2 are provided, and the two groups of cleaning mechanisms 2 are respectively provided corresponding to the two end faces of the battery cell 4. The two groups of cleaning mechanisms 2 can clean the two end faces of the battery cell 4 at the same time to improve the cleaning efficiency and thereby improve the production efficiency of the battery cell 4.
