[0029] At present, the assembly of conventional battery packs is spot welding, and then the nickel sheet is folded. After the nickel sheet is bent, PCM tape is pasted and the board is pre-folded. The pre-folded board currently uses a fixed pressing claw. This means that when the position of the tab changes, the jig must be redesigned, which makes the jig more limited. In order to solve the above technical problems.

[0030] like Figures 1 to 3 as well as Figure 5 As shown, in this embodiment, the battery cell folding jig includes: a mounting seat 10, a pressure plate 20, a pressure block 30 and a folding piece 40. A positioning space 11 for accommodating the battery 1 is provided on the mounting seat 10. The first end of the pressure plate 20 is connected to the mounting seat 10, and the pressure plate 20 is movably arranged and has a pressing position and an avoidance position that cooperates with the battery 1. The pressure block 30 is adjustably arranged at the second end of the pressure plate 20 along the width direction of the pressure plate 20, and the pressure block 30 is used to press the pole ear of the battery 1. The folding piece 40 is movably connected to the mounting seat 10, and the folding piece 40 is arranged toward the protective plate of the battery 1, and the folding piece 40 can bend the protective plate of the battery 1 when it moves.

[0031] By applying the technical solution of this embodiment, a positioning space 11 is provided on the mounting seat 10, and the positioning space 11 can accommodate the battery 1. The first end of the pressing plate 20 is connected to the mounting seat 10, and the pressing plate 20 is movably arranged and has a pressing position and an avoidance position that cooperates with the battery 1. The pressing block 30 is adjustably arranged at the second end of the pressing plate 20 along the width direction of the pressing plate 20, and the pressing block 30 is used to press the pole ear of the battery 1. The folding member 40 is movably connected to the mounting seat 10, and the folding member 40 is arranged toward the protective plate of the battery 1. When the folding member 40 swings, the protective plate of the battery 1 can be bent. Through the above-mentioned arrangement, the battery 1 is placed in the positioning space 11, and the pressing plate 20 can fix the battery 1 so that the position of the battery 1 in the positioning space 11 is more stable. The pressing block 30 is movably arranged at the second end of the pressing plate 20 and can press the pole ear of the battery 1, so that the pole ear can be effectively fixed, thereby making the position of the pole ear more stable. In this way, when the folding member 40 folds the protective plate, the tab will not shake, thereby achieving a better bending effect of the protective plate. And because the position of the pressing block 30 is adjustable, the battery cell folding plate jig can bend batteries of different sizes, thereby making the battery cell folding plate jig more versatile. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the tab position is unstable and thus affects the bending effect of the protective plate.

[0032] It should be noted that the above-mentioned movable setting includes a movable setting or a swingable setting. Specifically, in this embodiment, the first end of the pressure plate 20 is hingedly connected to the mounting seat 10, the pressure plate 20 is swingably set, and the folding member 40 is swingably connected to the mounting seat 10.

[0033] The battery cell folding jig of this embodiment adopts a movable pressing block 30, so that the position of the pressing block 30 can be moved according to the change of the position of the pole ear, so that the battery cell folding jig can be used more widely and universally, thereby improving the scope of use of the battery cell folding jig and reducing costs.

[0034] like Figures 1 to 3 as well as Figure 5 As shown, in this embodiment, the second end of the pressing plate 20 is provided with a guide groove 21, and the battery cell folding jig further includes a connecting member 50, which is connected between the guide groove 21 and the pressing block 30, and the position of the connecting member 50 is adjustably arranged in the guide groove 21. The setting of the guide groove 21 can make the moving direction of the pressing block 30 more fixed, and under the action of the connecting member 50, the pressing block 30 and the guide groove 21 can be connected together, thereby making the position of the pressing block 30 more stable, and the position of the pressing block 30 can be adjusted, so that the pressing block 30 can press the tab.

[0035] In this embodiment, the pressing block 30 includes a first pressing block and a second pressing block. The first pressing block is pressed and matched with the positive electrode tab, and the second pressing block is pressed and matched with the negative electrode tab.

[0036] like Figures 1 to 3 as well as Figure 5 and Figure 7 As shown, in this embodiment, the pressing block 30 includes a connecting plate 31 and a pressing plate 32 connected to each other, the connecting plate 31 is connected to the pressing plate 32, the pressing plate 32 extends toward one side of the mounting seat 10, and the pressing plate 32 protrudes from the pressing plate 20. The pressing plate 32 can press the tab, thereby making the position of the tab more stable. Specifically, the connecting plate 31 is located above the pressing plate 20, and the connecting plate 31 protrudes from one end of the pressing plate 20 toward the folding member 40 and is connected to the pressing plate 32.

[0038] like Figures 1 to 3 as well as Figure 5 and Figure 7 As shown, in this embodiment, the angle between the pressing plate 32 and the connecting plate 31 is greater than or equal to 90°. The above arrangement enables the pressing plate 32 to press the end of the tab close to the folding member 40, which can make the position of the tab more stable and limit the position of the fold.

[0039] Specifically, in this embodiment, the angle between the pressing plate 32 and the connecting plate 31 is 100°.

[0040] like Figures 1 to 3 as well as Figure 5 and Figure 6 As shown, in this embodiment, the folding member 40 includes a plate body 41, and a evasion portion 411 is provided on the plate body 41. When the folding member 40 moves to bend the protection plate of the battery 1, the evasion portion 411 evades the pressing block 30. Specifically, the above-mentioned movement is swinging, and the above-mentioned arrangement can avoid interference between the folding member 40 and the pressing block 30, thereby making the swing of the folding member 40 easier.

[0041] like Figures 1 to 3 as well as Figure 5 and Figure 6 As shown, in this embodiment, a protruding operating portion 412 is provided on one side of the plate body 41 away from the mounting seat 10. The provision of the protruding operating portion 412 can make the operation easier.

When the folding member 40 moves to bend the protection plate of the battery 1, the folding member 40 abuts against the limiter 60. The setting of the limiter 60 can limit the folding member 40, thereby preventing the folding member 40 from excessive movement, specifically, the above-mentioned movement is swinging.

[0043] like Figures 1 to 6 As shown, in this embodiment, the limiting member 60 includes a limiting block 61, which is located at the side of the positioning space 11. The limiting block 61 is provided with an inclined surface 611 and a flat surface 612 at one end facing the folding member 40. The inclined surface 611 is located between the flat surface 612 and the mounting seat 10. From the direction close to the folding member 40 to the first end of the pressing plate 20, the distance between the inclined surface 611 and the mounting seat 10 gradually decreases. The above-mentioned setting of the inclined surface 611 can avoid the folding member 40, and further can prevent the folding member 40 from being stuck with the limiting block 61 when the folding member 40 swings.

[0044] like Figure 3 , Figure 6 as well as Figure 7 As shown, in this embodiment, the battery cell folding jig further includes a positioning structure 70, which includes a positioning column 71 and a positioning groove 72, one of which is disposed on the mounting seat 10, and the other of which is disposed on the pressing plate 20.

[0045] like Figure 3 , Figure 6 as well as Figure 7 As shown, in this embodiment, the positioning groove 72 extends along the length direction of the mounting seat 10. The above arrangement can make the positioning effect of the pressing plate 20 more stable, and the positioning groove 72 is a long groove, so that the positioning column 71 can be inserted into the positioning groove 72.

[0046] like Figure 1 As shown, in this embodiment, the pressure plate 20 includes a main body and a first protrusion and a second protrusion located on both sides of the main body, and the positioning structure 70 is arranged between the first protrusion and the mounting seat 10, and the second protrusion is arranged to avoid the mounting seat 10, so that the operator can drive the second protrusion, thereby realizing the switching of the pressure plate 20 between the pressing position and the avoidance position.

[0047] Specifically, in this embodiment, the battery cell folding jig further includes a support seat, which is connected to the bottom of the mounting seat 10, and a suction cup structure is provided at the bottom of the support seat, so that the position of the support seat is fixed, thereby making the position of the mounting seat 10 more stable. The mounting seat 10 is tilted relative to the support seat, so that it is convenient for operators to use the battery cell folding jig.

[0048] The working process of the battery cell folding fixture of this embodiment is as follows:

[0049] The pressing plate 20 is opened to be in the avoidance position, the battery 1 is placed in the positioning space 11, the pressing plate 20 is driven to move from the avoidance position to the pressing position, the pressing block 30 is pressed on the pole ear of the battery 1, the folding member 40 is driven to swing, the swing of the folding member 40 drives the protection plate to move, and the protection plate is formed when the folding member 40 abuts and cooperates with the limit block 61. Finally, the pressing plate 20 is driven to move from the pressing position to the avoidance position, and the battery 1 is taken out from the positioning space 11.
