[0059] As part of the creative concept of this application, before describing the embodiments of this application, it is necessary to analyze the reasons why the state of the battery cells needs to be adjusted in the relevant technology, and obtain the technical solutions of the embodiments of this application through reasonable analysis.

[0060] In related technologies, battery cells are placed in a production line with their tabs aligned in a pre-set orientation to facilitate the gluing process. However, the orientation of the tabs of the paired cells, during the incoming material processing, intersects with the orientation during the subsequent gluing process. Therefore, the orientation of the tabs of the paired cells needs to be adjusted before gluing.

[0061] The present application adjusts the state of the battery cells placed on the working platform 10 by arranging a rotating assembly 12 on the frame 11 and a pitch-changing mechanism 2 connected to at least one frame 11 .

[0062] The present application provides a battery cell adjustment device. Figures 1 to 3 The battery cell adjustment device includes a support mechanism 1 and a pitch-changing mechanism 2. The support mechanism 1 includes a work platform 10, a frame 11, and a rotating assembly 12. There are at least two support mechanisms 1. The work platform 10 is rotatably connected to the frame 11 and is used to support the battery cells. The work platform 10 is driven and connected to the rotating assembly 12, which is mounted on the frame 11. The pitch-changing mechanism 2 is connected to at least one frame 11 and is used to adjust the spacing between adjacent support mechanisms 1.

[0063] Exemplarily, the battery cell is a square wound battery cell.

[0064] By way of example, the number of support mechanisms 1 is two.

[0065] Adjacent supporting structures 1 refer to supporting structures 1 used to support a group of paired battery cells.

[0066] In the solution of the embodiment of the present application, a rotating assembly 12 connected to the frame 11 and a pitch-changing mechanism 2 connected to at least one frame 11 are provided on the bearing mechanism 1. When the battery cell moves to the working platform 10, the rotating assembly 12 can rotate the working platform 10, so as to adjust the orientation of the paired battery cells to adapt to subsequent processes. The pitch-changing mechanism 2 can shorten the distance between two bearing mechanisms 1, so as to shorten the distance between the paired battery cells. In the embodiment of the present application, the position between the paired battery cells is adjusted by the rotating assembly 12 and the pitch-changing mechanism 2 to adapt to subsequent processing on the battery cell production line, so as to realize the adjustment of the state of the battery cell.

[0067] It should be noted that the state of the battery cell includes the position of the battery cell and / or the orientation of the tab of the battery cell.

[0068] Exemplarily, a plurality of rotating assemblies 12 are used to rotate the corresponding working platforms 10, so that the tabs of the battery cells carried by all the working platforms 10 have the same orientation and face the second preset direction, and the second preset direction is the arrangement direction of adjacent working platforms 10.

[0069] It can be understood that the same tab orientation means that the direction of the tab facing the pole piece of each battery cell is the same.

[0070] In one embodiment, please refer to Figure 1 and Figure 2 , the direction in which the pitch-changing mechanism 2 drives the corresponding frame 11 to move is parallel to the arrangement direction of adjacent bearing mechanisms 1.

[0071] Exemplarily, when the pitch-changing mechanism 2 is a telescopic motion mechanism, the direction in which the pitch-changing mechanism 2 drives the corresponding frame 11 to move is the telescopic direction of the pitch-changing mechanism 2.

[0072] In the solution of the embodiment of the present application, the direction in which the pitch-changing mechanism 2 drives the frame 11 to move is parallel to the arrangement direction of adjacent bearing mechanisms 1. The arrangement direction of the adjusted battery cells remains basically unchanged, and the relative positions of the paired battery cells can better adapt to subsequent processing procedures.

[0073] It can be understood that the present application is not limited to the direction in which the pitch-changing mechanism 2 drives the corresponding frame 11 to move being parallel to the arrangement direction of adjacent bearing mechanisms 1. In one embodiment, the direction in which the pitch-changing mechanism 2 drives the frame 11 to move is arranged crosswise with the arrangement direction of adjacent bearing mechanisms 1.

[0076] In the solution of the embodiment of the present application, the variable pitch mechanism 2 includes a cylinder 20, a slide rail 21 and a slider 22. The cylinder 20 applies a driving force to the rack 11 arranged on the moving end by driving the moving end.

The variable pitch mechanism 2 has a simple structure and can relatively stably adjust the distance between adjacent bearing mechanisms 1.

[0077] It can be understood that the present application is not limited to the variable pitch mechanism 2 including a cylinder 20, a slide rail 21 and a slider 22 to adjust the distance between adjacent racks 11. In one embodiment, the variable pitch mechanism 2 includes an engine, a gear and a rack. The gear is drivingly connected to the engine, and the gear meshes with the rack. The end of the rack is connected to one of the racks 11. The engine can drive the gear to rotate, thereby driving the rack to expand and contract, so as to adjust the distance between adjacent racks 11.

[0087] Exemplarily, the material of the first limiting block and / or the second limiting block is a material that can produce elastic deformation.

[0088] Exemplarily, the first direction 3a and the second direction 3b are arranged orthogonally.

[0089] Exemplarily, one of the first direction 3a and the second direction 3b is parallel to the arrangement direction of the adjacent carrying mechanisms 1.

[0090] In the embodiments of the present application, the limiting mechanism 30 includes a first positioning component 300 and a second positioning component 301. The first positioning component 300 and the second positioning component 301 can respectively position the battery cell in the first direction 3a and the second direction 3b. The battery cell is positioned in the first direction 3a and the second direction 3b that intersect each other. During the process of pairing and connecting the battery cells, the pairing process is relatively precise, and the situation of defects in the finished product is alleviated.

[0091] On the other hand, the present application provides a battery cell adjustment assembly. The battery cell adjustment assembly includes the battery cell adjustment device in any of the above embodiments. A plurality of battery cell adjustment devices are arranged at intervals along a first preset direction, and the first preset direction is arranged intersecting with the arrangement direction of adjacent bearing mechanisms 1.

[0092] Exemplarily, the first preset direction is arranged orthogonally to the arrangement direction of adjacent bearing mechanisms 1.

[0093] In the embodiments of the present application, the battery cell adjustment assembly includes a plurality of battery cell adjustment devices arranged at intervals along a first preset direction. The plurality of battery cell adjustment devices can adjust the states of multiple pairs of paired battery cells, so as to be able to adapt to the processing of battery monomers with multiple stacked battery cells.

[0094] On the other hand, the present application provides a method for adjusting the state of a battery cell. Please refer to Figure 4 , the method includes:

[0095] Step S1: Rotate the corresponding working platforms respectively through a plurality of rotating components, so that the tabs of the battery cells placed on the working platforms face a second preset direction;

[0096] Step S2: Drive at least one bearing mechanism through a pitch-changing mechanism to shorten the distance between adjacent working platforms;

[0097] Wherein, the second preset direction is the arrangement direction of adjacent working platforms.

[0098] The tab orientation refers to the direction from the electrode plate to the tab.

[0099] Exemplarily, the second preset direction is parallel to the arrangement direction of adjacent bearing mechanisms 1. In the embodiments of the present application, the method for adjusting the state of the battery cell rotates the corresponding working platforms 10 respectively through a plurality of rotating components 12 to adjust the orientation of the battery cells placed on the working platforms 10, and then shortens the distance between the corresponding bearing mechanisms 1 through the pitch-changing mechanism 2. In the embodiments of the present application, the states of the paired battery cells are adjusted through the rotating components 12 and the pitch-changing mechanism 2 to adapt to subsequent processing on the battery cell production line, thereby improving the automation degree of battery production.

[0100] In one embodiment, please refer to Figure 5, before the pole ears of the battery cells placed on the working platforms 10 are oriented towards the second preset direction by respectively rotating the corresponding working platforms 10 through a plurality of rotating components 12, the method further includes:

[0101] Step S3: Position the battery cells located on adjacent working platforms respectively through the positioning component.

[0102] In the embodiment of the present application, during the process of adjusting the battery cells, the positioning component 3 can accurately position the battery cells, so that the state of the battery cells after adjustment can better adapt to the subsequent processing procedures.

[0103] In one embodiment, please refer to Figure 6 , the positioning component 3 includes a limiting mechanism 30. At least one limiting mechanism 30 is a first limiting mechanism 30, and at least one limiting mechanism 30 is a second limiting mechanism 30. The first limiting mechanism 30 and the second limiting mechanism 30 are respectively connected to adjacent working platforms 10. Positioning the battery cells located on adjacent working platforms 10 respectively through the positioning component 3 includes:

[0104] Step S30: Position one of the battery cells along a first direction and a second direction through the first limiting mechanism;

[0105] Step S31: Position the other battery cell along the first direction and the second direction through the second limiting mechanism;

[0106] Wherein, the first direction 3a and the second direction 3b are arranged crosswise.

[0107] It should be noted that there is no clear sequence between step S30 and step S31, and step S30 and step S31 can be executed synchronously.

[0108] In the embodiment of the present application, the first limiting mechanism 30 and the second positioning mechanism respectively position different battery cells, which can alleviate the interference between the limiting mechanisms 30, thereby improving the production efficiency. Moreover, the battery cells are positioned in the mutually crosswise first direction 3a and second direction 3b. During the process of pairing and connecting the battery cells, the pairing process is more accurate and the situation of defects in the finished products is alleviated.

[0109] In one embodiment, please refer to Figure 7 , the pole ears of the battery cells placed on the working platforms 10 are oriented towards the second preset direction by respectively rotating the corresponding working platforms 10 through a plurality of rotating components 12, including:

[0110] Step S10: Rotate the corresponding working platforms in the same direction by 90° respectively through a plurality of rotating components, so that the pole ears of the battery cells placed on the working platforms are oriented towards the second preset direction.

[0111] Co-rotating means that the corresponding working platforms 10 all rotate in the clockwise or counterclockwise direction.

[0112] Exemplarily, multiple rotating components 12 respectively rotate the corresponding working platforms 10 counterclockwise by 90°.

[0113] In the embodiments of the present application, multiple rotating components 12 respectively drive the corresponding working platforms 10 to rotate co-directionally by 90°, and the working platforms 10 rotate by a smaller angle to make the tabs of the battery cells face an appropriate angle, improving the adjustment efficiency.

[0114] Please refer to Figure 8 , and the method will be described through the following embodiments.
