The substrate 100 is disposed in the forming cavity of the battery formation equipment; the fixed component 200 is disposed at one end of the substrate 100; the movable component 300 moves along the length direction of the substrate 100, and the movable component 300 is slidably connected to the edge of the substrate 100. Wherein, both the fixed component 200 and the movable component 300 are provided with a PCB wiring module 400 for electrically connecting the battery cells, and the distance between the two groups of PCB wiring modules 400 increases or decreases as the movable component 300 moves.
[0040] In this embodiment, the number of the fixed component 200 and the movable component 300 is both two groups. The two groups of fixed components 200 are respectively disposed at both ends of the substrate 100, and the two groups of movable components 300 are slidably connected to the edge of the substrate 100. Adopting double-station battery cell clamping is beneficial to improving the formation efficiency.
[0041] The PCB wiring module 400 is respectively arranged on the fixed component 200 and the movable component 300. The two groups of PCB wiring modules 400 are respectively used to connect the leads of the cells to be formed. When it is necessary to replace cells of different sizes, the operator only needs to disassemble the original cells, and then drive the movable component 300 to move along the edge of the substrate 100 in a straight line direction for a preset path until it adapts to the size of the new cells. The operator installs the new cells on the PCB wiring module 400, thereby completing the charging and forming operation for different sizes of materials. Compared with the prior art, the cell clamping tooling has the technical problems of poor flexibility and inconvenient use. The fully compatible polymer soft-pack lithium-ion battery charging and forming clamping tooling provided by the embodiment of the present invention can realize the full-size compatibility effect by setting the movable component 300 that can move appropriately, so that the distance between the two wiring PCB modules can be fully adapted to cells of different sizes, effectively improving the practicability of the fully compatible polymer soft-pack lithium-ion battery charging and forming clamping tooling, which is beneficial to the development of enterprises.

[0044] As Figures 1 to 8 shown, further, the connecting component 220 includes a first connecting block 221, a first pin 222, a second connecting block 223 and a second pin 224. The first connecting block 221 and the second connecting block 223 are sequentially arranged along the height direction of the substrate 100 at the bottom edge and the bottom edge of the substrate 100. The first pin 222 is arranged at the end of the first connecting block 221 away from the substrate 100, the second pin 224 is arranged at the end of the second connecting block 223 away from the substrate 100.

[0045] Specifically, the use of the bolt structure can fully adapt to the structural characteristics of the support chain rope 800. The insertion fit of the chain hole and the bolt is beneficial to improving the structural optimization degree of the connecting component 220, and further improving the structural stability of the formation clamping tooling for fully compatible polymer soft-pack lithium-ion batteries.
[0046] As Figures 1 to 8 shown, further, a groove 225 is provided at the end of the first connecting block 221 away from the substrate 100.

Specifically, the groove 225 is arranged in a semi-circular groove structure. The first connecting block 221 does not need to be positioned and installed with the support sliding shaft 900. It only needs to be lapped on the support sliding shaft 900 to complete the installation and achieve the effect of sliding fine adjustment, further simplifying the structure.
[0047] As Figures 1 to 8 shown, further, the movable assembly 300 includes a moving block 310 and a mounting block 320. The moving block 310 is slidably connected to the edge of the substrate 100. The mounting block 320 is fixedly arranged on the moving block 310. A guide rail 330 is arranged on the edge of the substrate 100. The moving block 310 is slidably adapted to the guide rail 330. The number of the moving block 310, the guide rail 330 and the mounting block 320 is two groups. The two groups of guide rails 330 are distributed at both ends of the substrate 100. The two groups of moving blocks 310 are respectively slidably connected to the corresponding guide rails 330. The two groups of mounting blocks 320 are respectively arranged on the corresponding moving blocks 310.

The buffer assembly 500 is detachably connected to the fixed assembly 200 or the movable assembly 300. Since there are multiple groups of clamping toolings closely arranged on the same group of support sliding shafts 900, the use of the buffer assembly 500 is beneficial to preventing the battery cells on adjacent two groups of clamping toolings from being damaged due to excessive pressure, and further improving the practicability of the clamping tooling.
[0049] As Figures 1 to 8As shown in the figure, further, the buffer assembly 500 includes an elastic member 510, a connecting plate 520, and a buffer plate 530. The connecting plate 520 is detachably connected to the fixed assembly 200 or the movable assembly 300. The buffer plate 530 is slidably connected to the connecting plate 520. The elastic member 510 abuts between the buffer plate 530 and the connecting plate 520.

[0051] In this embodiment, clamping bosses 600 are provided on the first connecting block 221, the mounting block 320, and the second connecting block 223. Clamping grooves 522 are respectively provided at both ends of the connecting plate 520. The clamping grooves 522 are snap-fitted with the clamping bosses 600. Using snap-fastening for disassembly and assembly can improve the installation convenience of the buffer assembly 500, and thus improve the practicality of the clamping tooling.
[0052] As Figures 1 to 8 shown in the figure, further, the number of the sliding boards 532 is at least two groups, and all the sliding boards 532 are symmetrically distributed on both side edges of the main board 531. Adopting the structure of multiple groups of sliding boards 532 is beneficial to improving the stability of the buffer assembly 500 and preventing the buffer plate 530 from loosening. The elastic member 510 is a compression spring.
