[0024] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0025] In the manufacturing process of battery modules, cell stacking is a key process step, directly affecting the overall structural stability, electrical performance consistency, and subsequent assembly efficiency of the module. Currently, in the production of power batteries and energy storage batteries, multiple cells are typically stacked manually or semi-automatically to form a battery module with a specific geometric structure and electrical connections.

[0026] However, existing cell stacking methods suffer from low efficiency, low automation, and poor stacking accuracy. Specifically, traditional stacking equipment or tooling lacks precise control over cell positioning and compression, leading to multiple cells being prone to positional offsets, height inconsistencies, and tilting during the stacking process, which in turn affects the overall dimensional accuracy and structural reliability of the battery module. Furthermore, some stacking devices are complex and difficult to adjust, making them difficult to adapt to the rapid switching of cells of different specifications, limiting the flexibility and intelligent development of production lines.

[0027] Based on the problems existing in the existing technology, please refer to Figure 1 and Figure 2 The embodiment of the present invention provides a battery cell stacking tool 10 with a reasonable structure, precise positioning, and efficient operation, so as to improve the stacking consistency and production automation level and meet the requirements of modern battery manufacturing for high quality, high efficiency, and low cost.

[0028] In detail, the battery cell stacking tool 10 includes a base 100 , a first stacking station 200 and a second stacking station 300 .

[0029] The first stacking station 200 is provided on the base 100. The first stacking station 200 is provided with a first placement portion 240 and a plurality of first through holes 231. The first placement portion 240 is used to place the battery cell mounting plate 11 so as to stack the first battery cell layer 12 on one side of the battery cell mounting plate 11. The plurality of first through holes 231 are used to correspond one-to-one with the plurality of battery cells in the first battery cell layer 12 to reveal the identity of the battery cells. The second stacking station 300 is arranged on the base 100. The second stacking station 300 is provided with a second placement portion 340 and a plurality of second through holes 331. The second placement portion 340 is used to place the battery cell mounting plate 11 to stack the second battery cell layer 13 on the other side of the battery cell mounting plate 11. The plurality of second through holes 331 are used to correspond one-to-one with the plurality of battery cells of the first battery cell layer 12 and the second battery cell layer 13 to reveal the identity of the battery cells.

[0030] In this embodiment, the cell mounting plate 11 is placed on the first placement portion 240 to secure the cell mounting plate 11, thereby ensuring that multiple cells can be stably stacked on the cell mounting plate 11 to form a first cell layer 12. The first through-holes 231 expose the multiple cell identity marks of the first cell layer 12, which not only allows detection of consistent stacking of the multiple cells of the first cell layer 12 on the cell mounting plate 11, but also allows the identification mechanism to uniformly identify the multiple cells, thereby facilitating traceability and management of the cells in subsequent processes. After the first battery cell layer 12 is fixed on the battery cell mounting plate 11, the battery cell mounting plate 11 is turned over and transferred to the second stacking station 300 to fix the battery cell mounting plate 11, and the battery cells are stacked on the other side of the battery cell mounting plate 11 to form a second battery cell layer 13. At the same time, the multiple second through holes 331 are made to correspond one-to-one with the multiple battery cells of the first battery cell layer 12 and the second battery cell layer 13 to reveal the multiple battery cell identity labels of the first battery cell layer 12 and the second battery cell layer 13, and the stacking consistency of the battery cells is checked again.

[0031] It can be understood that each battery cell end is provided with an identification mark, which can be, but is not limited to, a QR code or the like.

[0032] Furthermore, the first stacking station 200 includes a first pad 210, a first limiter 220 and a first side plate 230. The first pad 210 and the first limiter 220 are both arranged on the base 100. There are two first limiters 220 and they are respectively arranged at both ends of the first pad 210. The first side plate 230 is arranged on one side of the base 100. The first pad 210, the first limiter 220 and the first side plate 230 together form a first placement portion 240. A plurality of first through holes 231 are arranged in a row on the first side plate 230 along the length direction of the first side plate 230.

[0033] In this embodiment, both ends of the cell mounting plate 11 are respectively overlapped on the two first limiting members 220, so that the cell mounting plate 11 is limited and fixed by the two first limiting members 220, thereby ensuring that the cells can be stably stacked on the cell mounting plate 11.

[0034] It can be understood that the battery cell mounting plate 11 is sequentially provided with a plurality of mounting grooves along the length direction so that a plurality of battery cells can be respectively placed in the plurality of mounting grooves.

[0035] Furthermore, the first stacking station 200 also includes a first inner plate 250, which is arranged between the first side plate 230 and the first pad 210 and the first limit member 220. The first inner plate 250 is provided with a plurality of third through holes 251, and the plurality of third through holes 251 correspond one-to-one to the plurality of first through holes 231.

[0036] In order to ensure the stacking consistency of multiple battery cells after they are stacked on the battery cell mounting plate 11, the ends of multiple battery cells need to be abutted against the first side plate 230. In order to reduce the damage caused by the abutment between the battery cells and the first side plate 230, a first inner plate 250 is provided inside the first side plate 230 to protect the battery cells to a certain extent.

[0037] In addition, in order to ensure the installation stability of the first side panel 230, the first stacking station 200 also includes a first support member 260. The first support member 260 is triangular, and the two sides of the first support member 260 are respectively connected to the base 100 and the first side panel 230 to improve the installation stability of the first side panel 230.

[0038] Furthermore, the second stacking station 300 includes a second pad 310, a second limiter 320 and a second side plate 330. The second pad 310 and the second limiter 320 are both arranged on the base 100. There are two second limiters 320 and they are respectively arranged at both ends of the second pad 310. The second side plate 330 is arranged on the other side of the base 100. The second pad 310, the second limiter 320 and the second side plate 330 together form a second placement portion 340. A plurality of second through holes 331 are arranged in two rows along the length direction of the second side plate 330.

[0039] In this embodiment, the two ends of the battery cell mounting plate 11 are also overlapped on the two second limit members 320 respectively, and the first battery cell layer 12 is placed downward, so that multiple battery cells can be placed on the top side of the battery cell mounting plate 11 to form a second battery cell layer 13; at this time, the first battery cell layer 12 and the second battery cell layer 13 are corresponded to the multiple second through holes 331, thereby revealing the identity identification of multiple battery cells.

[0040] Furthermore, the second stacking station 300 also includes a second inner plate 350, which is arranged between the second side plate 330 and the second pad 310 and the second limit member 320. The second inner plate 350 is provided with multiple fourth through holes 351, and the multiple fourth through holes 351 correspond one-to-one to the multiple second through holes 331.

[0041] In order to ensure the stacking consistency of multiple battery cells after they are stacked on the battery cell mounting plate 11, the ends of multiple battery cells need to be abutted against the second side plate 330. In order to reduce the damage caused by the abutment between the battery cells and the second side plate 330, a first inner plate 250 is provided inside the second side plate 330 to protect the battery cells to a certain extent.

[0042] Optionally, the first inner panel 250 and the second inner panel 350 may be made of a flexible material.

[0043] In addition, in order to ensure the installation stability of the second side panel 330, the second stacking station 300 also includes a second support member 360. The second support member 360 is triangular, and the two sides of the second support member 360 are respectively connected to the base 100 and the second side panel 330 to improve the installation stability of the second side panel 330.

[0044] Furthermore, the battery cell stacking tool 10 further includes a baffle 400 , which is disposed between the first stacking station 200 and the second stacking station 300 . The baffle 400 is used to push the multiple battery cells into contact with the first side plate 230 or the second side plate 330 .

[0045] In this embodiment, when the battery cell mounting plate 11 is placed on the first stacking station 200 and multiple battery cells are placed on the battery cell mounting plate 11, in order to ensure the stacking consistency of the multiple battery cells, the battery cells can be pushed by the baffle 400 so that the multiple battery cells forming the first battery cell layer 12 are all in contact with the first inner plate 250 on the inner side of the first side plate 230.

[0046] Similarly, when the battery cell mounting plate 11 is placed on the second stacking station 300 and multiple battery cells are placed on the battery cell mounting plate 11, the multiple battery cells can also be pushed by the baffle 400 so that the multiple battery cells forming the second battery cell layer 13 are all in contact with the second inner plate inside the second side plate 330.

[0047] In order to further ensure the stacking consistency and stability of the multiple battery cells, the battery cell stacking tool 10 further includes a pressing plate 500, which is used to press the top of the multiple battery cells.

[0048] Furthermore, the cell stacking tool 10 further includes an insulating spacer 600 , which is disposed between the first station and the second station, thereby playing an isolation role.

[0049] Furthermore, a plurality of support columns 110 are provided on the bottom wall of the base 100 , and the plurality of support columns 110 are arranged at intervals, thereby enhancing the structural stability and rigidity of the base 100 .

[0050] Furthermore, an embodiment of the present invention also provides a battery cell stacking method, which is applied to the battery cell stacking tool 10 in the above embodiment.

[0051] The cell stacking method includes the following steps: Step S100: placing a cell mounting plate 11 on a first stacking station 200, and placing a plurality of cells on the cell mounting plate 11 to form a first cell layer 12 on the cell mounting plate 11; Specifically, the cell mounting plate 11 is placed between the two first limiters 220 , and glue of a preset weight is applied on the cell mounting plate 11 , and a plurality of cells are arranged and mounted on the cell mounting plate 11 and fixed to form a first cell layer 12 .

[0052] It is worth noting that during installation, the identity labels on the surface of the battery cells need to be placed in a preset direction. After the first battery cell layer 12 is arranged, the tails of the multiple battery cells in the first battery cell layer 12 are flattened through the baffle 400 and squeezed to the first inner plate 250, and then flattened using the pressing plate 500 above the first row of battery cells.

[0053] Step S200 , aligning the identification marks of the plurality of battery cells in the first battery layer 12 with the plurality of first through holes 231 one by one, and making the identification marks of the plurality of battery cells in the first battery layer 12 uniformly face the first direction; In this embodiment, the first direction is vertically downward. Therefore, the first through holes 231 are used to check whether the identification marks of the first battery cell layer 12 are all facing downward. If there are battery cells facing other directions, the identification marks of the battery cells can be turned downward in time.

[0054] Step S300: After the first battery cell layer 12 is fixed to the battery cell mounting plate 11, the battery cell mounting plate 11 is flipped and transferred to the second stacking station 300; After the glue on the first battery cell layer 12 and the battery cell mounting plate 11 solidifies, the battery cell mounting plate 11 can be turned over and placed on the two second limiting members 320 for fixation.

[0055] Step S400 , placing a plurality of battery cells on the other side of the battery cell mounting plate 11 to form a second battery cell layer 13 on the battery cell mounting plate 11 ; It should be noted that before placing the battery cells, it is still necessary to apply glue of a preset weight on the battery cell mounting plate 11 , and then arrange the battery cells on the battery cell mounting plate 11 to form the second battery cell layer 13 .

[0056] In step S500 , the identification marks of the plurality of cells in the first cell layer 12 and the second cell layer 13 are matched one-to-one with the plurality of second through holes 331 , and the plurality of cells in the first cell layer 12 and the second cell layer 13 are uniformly oriented in a second direction opposite to the first direction.

[0057] In this embodiment, the second direction is vertically upward. Therefore, the identification marks of the first and second cell layers 12, 13 are checked one by one through the second through-holes 331 to ensure they are consistent and facing upward. The baffle 400 is aligned with the tails of the multiple cells in the first and second cell layers 12, 13 and pressed against the second inner plate 350. The pressing plate 500 is then pressed against the top of the second cell layer 13 to flatten the multiple cells and allow them to rest. Once the glue between the second cell layer 13 and the cell mounting plate 11 solidifies, the cell stacking process is complete. The pressed and solidified module is then removed for the next step.

[0058] In summary, the embodiment of the present invention provides a battery cell stacking tool 10 and a battery cell stacking method, which ensures that the first battery cell layer 12 formed by stacking multiple battery cells has good consistency by placing the battery cell mounting plate 11 on the first placement portion 240 to stably fix the battery cells; at the same time, the first through hole 231 is used to reveal the battery cell identity mark, which is convenient for the identification mechanism to uniformly identify and detect the stacking quality, which is conducive to improving the degree of automation and battery cell traceability management efficiency; not only that, after completing the stacking of the first battery cell layer 12, the battery cell mounting plate 11 is flipped over and transferred to the second stacking station 300, and the stacking is continued to form the second battery cell layer 13, and the identity mark of each battery cell is revealed again through the second through hole 331, so as to realize the synchronous detection and identification of the two layers of battery cells. This method not only improves the stacking accuracy and production efficiency, but also effectively guarantees the consistency and traceability of multi-layer battery cell stacking, and provides reliable technical support for subsequent assembly and quality control.

[0059] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
