[0039] A first side pressing mold set 31 and a second side pressing mold set 32, wherein the first side pressing mold set 31 and the second side pressing mold set 32 ​​are symmetrically arranged on both sides of the carrying platform 2, and the first side pressing mold set 31 and the second side pressing mold set 32 ​​are used to press the battery cell 5 from both sides of the carrying platform 2;

[0040] The first end compression mold group 41 and the second end compression mold group 42 are symmetrically arranged on both sides of the supporting platform 2, and the first end compression mold group 41 and the second end compression mold group 42 are used to compress the battery cell 5 from both ends of the supporting platform 2; the first end compression mold group 41 is provided with an end pressure fixing structure connected to the second fixing structure.

[0041] It should be noted that the present embodiment improves the structure of the existing stacking device, wherein the carrying platform 2 is connected to the first fixed structure on the mounting plate 1 via the platform fixing structure, and the first end die set 41 is connected to the second fixed structure on the mounting plate 1 via the second fixed structure. The carrying platform 2 and the first end die set 41 can adjust their positions on the mounting plate 1 through the above-mentioned fixed structure according to the size of the actual battery cell 5 product, thereby adapting to the stacking operation of battery cell 5 products of different sizes, greatly improving the compatibility of the stacking device and reducing the equipment investment cost.

[0042] Specifically, refer to Figure 2 and Figure 3 The first fixing structure is provided with a plurality of first mounting holes 11 opened along the length direction of the mounting plate 1, and the platform fixing structure is provided with a plurality of first through holes 21 docking with the first mounting holes 11, and the first through holes 21 are fixedly connected with the first mounting holes 11 by fixing members.

[0043] refer to Figure 2 and Figure 6 The second fixing structure is configured as a plurality of second mounting holes 12 opened along the length direction of the mounting plate 1, and the end pressure fixing structure is configured as a plurality of second through holes 411 docking with the second mounting holes 12, and the second through holes 411 are fixedly connected to the second mounting holes 12 by fixing members.

[0044] In this embodiment, the first fixing structure and the second fixing structure are respectively configured as mounting hole structures opened along the length direction of the mounting plate 1 (see Figure 2 The hole structure in the dotted box), and the first through hole 21 is opened in the supporting platform 2 corresponding to the first mounting hole 11, and the second through hole 411 is opened in the first end die set 41 corresponding to the second mounting hole 12. Specifically, the mounting hole and the through hole can be set as threaded holes, and the fixing structure can be set as bolts with a threaded structure. The mounting hole and the through hole structure are connected and fixed by bolts to ensure the installation stability of the supporting platform 2 and the first end die set 41. At the same time, when the position of the two needs to be adjusted, it is only necessary to loosen the bolts, push the supporting platform 2 and the first end die set 41 along the length direction of the mounting plate 1, and connect them to the mounting holes at other positions, which is simple and convenient.

[0045] Further, refer to Figure 4The first side pressing module group 31 and the second side pressing module group 32 both include a side pressing mounting seat 311, on which a side pressing tooling for pressing the side surface of the battery cell 5 can be detachably mounted, and the side pressing tooling includes a side pressing mounting plate 3121 detachably connected to the side pressing mounting seat 311, and a side clamping plate 313 is provided on the mounting plate 1.

[0046] In this embodiment, the first side pressure module 31 and the second side pressure module 32 are both clamped from both sides of the battery cell 5 by the side clamping plates 313 on the side pressure tooling. When the size of the battery cell 5 to be stacked changes, it is only necessary to remove the side pressure tooling from the side pressure mounting seat 311 and replace it with a side pressure tooling of a matching size. There is no need to replace the entire side pressure module, which is easy to operate and has stronger compatibility. Specifically, the side pressure mounting plate 3121 of the side pressure tooling and the side pressure mounting seat 311 are respectively provided with threaded hole structures, and the two are connected and fixed by bolts, which ensures the stability of the structure while facilitating disassembly and replacement.

[0047] Furthermore, the first side pressing die set 31 and the second side pressing die set 32 ​​are both provided with a side pressing bottom plate 314, and the side pressing bottom plate 314 is provided with a first side pressing driving mechanism 315 for driving the side pressing mounting seat 311 to approach or move away from the side of the battery cell 5. In this embodiment, the side pressing fixture can be clamped and loosened on the battery cell 5 by the first side pressing driving mechanism 315 to drive the side pressing mounting seat 311 to approach or move away from the side of the battery cell 5, thereby ensuring the stability of the battery cell 5 and facilitating the loading and unloading of the battery cell 5.

[0048] Furthermore, the first side pressing module 31 and the second side pressing module 32 are both provided with a second side pressing driving mechanism 316 for driving the side pressing bottom plate 314 to move along the length direction of the mounting plate 1, and the side pressing bottom plate 314 is connected to the driving end of the second side pressing driving mechanism 316. In this embodiment, the side pressing bottom plate 314 is driven by the second side pressing driving mechanism 316 to perform reciprocating linear motion along the length direction of the mounting plate 1, so that the reciprocating linear motion of the entire side pressing module along the length direction of the mounting plate 1 can be achieved, further facilitating the loading and unloading of the battery cells 5.

[0049] Further, refer to Figure 5 and Figure 6, both the first end pressing module 41 and the second end pressing module 42 include an end pressing mounting seat 412, and a end pressing tooling 413 for pressing the end face of the battery cell 5 is detachably mounted on the end pressing mounting seat 412. In this embodiment, the end pressing tooling 413 is arranged in a U-shaped structure for clamping the end face of the battery cell 5. When the size of the battery cell 5 to be stacked changes, only the end pressing tooling 413 needs to be removed from the end pressing mounting seat 412 and replaced with an end pressing tooling 413 of a suitable size, without replacing the entire end pressing module, which is simple to operate and has stronger compatibility. Specifically, threaded hole structures are respectively formed on the end pressing tooling 413 and the end pressing mounting seat 412, and the two are connected and fixed by bolts, which not only ensures the structural stability but also facilitates disassembly and replacement.

[0050] Furthermore, both the first end pressing module 41 and the second end pressing module 42 are provided with a first end pressing driving mechanism 414 for driving the end pressing tooling 413 to approach or move away from the end of the battery cell 5. In this embodiment, by driving the end pressing tooling 413 to approach or move away from the side of the battery cell 5 through the first end pressing driving mechanism 414, the end pressing tooling 413 can clamp and release the end face of the battery cell 5, ensuring the stability of the battery cell 5 and facilitating the loading and unloading of the battery cell 5.

[0051] Furthermore, both the first end pressing module 41 and the second end pressing module 42 are provided with a second end pressing driving mechanism 415, and a pressing tooling 416 is detachably mounted on the driving end of the second end pressing driving mechanism 415. The pressing tooling 416 is used to press the battery cell 5 from the top of both ends of the battery cell 5. In this embodiment, by driving the pressing tooling 416 to approach or move away from the top surface of the end of the battery cell 5 through the second end pressing driving mechanism 415, the pressing tooling 416 can press and release the top surface of the end of the battery cell 5, further ensuring the stability of the battery cell 5 and facilitating the loading and unloading of the battery cell 5. In this embodiment, the pressing tooling 416 is arranged in a structure of two pressing rods, which not only ensures stable pressing but also has a simpler structure.

[0052] Furthermore, a third end pressing driving mechanism 417 is further provided on the fixing plate. The third end pressing driving mechanism 417 is used to drive the second end pressing module 42 to approach or move away from the end of the battery cell 5, and the second end pressing module 42 is connected to the driving end of the third end pressing driving mechanism 417. In this embodiment, by driving the second end pressing module 42 to approach or move away from the end of the battery cell 5 through the third end pressing driving mechanism 417, before loading, the third end pressing driving mechanism 417 drives the second end pressing module 42 to move away from the end of the battery cell 5, increasing the space between the first end pressing module 41 and the second end pressing module 42 and facilitating the loading of the battery cell 5. After the battery cell 5 is loaded, the third end pressing driving mechanism drives the second end pressing module 42 to approach the end of the battery cell 5, facilitating subsequent clamping of the battery cell 5.

[0053] Furthermore, it should be noted that the above-mentioned first side pressure drive mechanism 315, second side pressure drive mechanism 316, first end pressure drive mechanism 414, second end pressure drive mechanism 415 and third end pressure drive mechanism 417 can be set as linear drive mechanisms commonly used in the prior art, such as motor screw drive modules, cylinders, etc. In this embodiment, cylinder drive is adopted to ensure power stability while reducing costs and simplifying the structure.

[0054] The pressing tool 416 can press and release the top surface of the end of the battery cell 5, further ensuring the stability of the battery cell 5 and facilitating the loading and unloading of the battery cell 5. In this embodiment, the pressing tool 416 is configured as two pressing rods, which ensures the stability of the pressing and makes the structure simpler.

[0055] The above description is only an optional embodiment of the utility model, and does not limit the patent scope of the utility model.
