Taking "A and / or B" as an example, it includes solution A, or solution B, or the solution where A and B are satisfied simultaneously. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0037] In order to improve the versatility of the battery cell positioning mechanism, the present technical solution proposes a battery cell positioning fixture, including:

[0038] A base 100, provided with a workbench for carrying the battery cell;

[0039] A first positioning component 200, arranged on the workbench, and the first positioning component 200 is used to clamp or release the battery cell in the first direction;

[0040] Two second positioning components 300, arranged on opposite sides of the workbench along the second direction, and the two second positioning components 300 relatively expand and contract to clamp or release the battery cell, and the second direction is perpendicular to the first direction;

[0041] A limit component 400, arranged on the second positioning component 300 to limit the expansion and contraction of the second positioning component 300 along the second direction.

[0042] As Figure 1 and Figure 2 , in an embodiment of the present utility model, the cell positioning jig includes a base 100 which can be fixed on any device of the cell production line. A horizontally arranged workbench is provided on the base 100, and the workbench can place the cell. A first positioning component 200 is provided on the workbench. The first positioning component 200 can be two relatively telescopic cylinders. The first positioning component 200 can clamp or release the cell in the first direction to achieve the positioning of the cell in the first direction. The first direction can be the long side direction or the short side direction of the cell, and there is no limitation here. In addition, a second positioning component 300 is also provided on the workbench. The second positioning component 300 can adopt a structure similar to that of the first positioning component 200. Two second positioning components 300 can be provided, and the two second positioning components 300 can be arranged on the opposite sides of the workbench along the second direction. The second direction is a direction perpendicular to the first direction. The two second positioning components 300 relatively telescope to clamp or release the cell to achieve the positioning of the cell in the second direction. Thus, through the cooperation of the first positioning component 200 and the second positioning component 300, the positioning of the cell in the long side direction and the short side direction can be achieved. In addition, since the clamping range of the first positioning component 200 in the first direction is adjustable and the clamping range of the second positioning component 300 in the second direction is adjustable, the cell positioning jig can be adapted to the positioning of cells with different lengths or different widths, so as to improve the versatility of the cell positioning jig. In addition, the cell positioning jig further includes a limiting component 400. The limiting component 400 can be a guiding structure provided on the second positioning component 300. The limiting component 400 can limit the second positioning component 300 to only telescope along the second direction, so as to ensure that the second positioning component 300 always positions the cell in the second direction, improve the accuracy of cell positioning, and further ensure the reliability of the operation of the cell positioning jig.

[0043] As Figure 1 , in an embodiment of the present utility model, the second positioning component 300 includes:

[0044] A first telescopic member 310 having a first fixed end and a first telescopic end. The first fixed end is connected to the base 100, and the first telescopic end telescopes along the second direction;

[0045] A first positioning member 320 is provided on the first telescopic end. The first positioning member 320 is used to abut against the side wall of the cell.

[0046] In this embodiment, the second positioning component 300 is composed of a first telescopic member 310 and a first positioning member 320. The first telescopic member 310 includes a first fixed end and a first telescopic end. The first fixed end is firmly connected to the base 100, ensuring the stability of the entire component; while the first telescopic end can freely expand and contract along the second direction. The first telescopic member 310 can adopt a structure similar to a cylinder or a hydraulic cylinder. Through the expansion and contraction of the first telescopic member 310, the second positioning component 300 can be dynamically adjusted according to the actual size of the battery cell to achieve the best positioning effect. In addition, the first positioning member 320 is installed at the first telescopic end and directly faces and abuts against the side wall of the battery cell. When the first telescopic member 310 performs an expansion and contraction action, the first positioning member 320 moves accordingly. Through the close contact between the first positioning member 320 and the side wall of the battery cell, precise positioning of the battery cell in the second direction is achieved. The shape and size of the first positioning member 320 can be flexibly adjusted according to the structure of the battery cell to ensure the degree of fit with the surface of the battery cell, ensuring that while applying appropriate pressure, the battery cell will not be damaged.

[0047] As Figure 1 , in an embodiment of the present utility model, the limiting component 400 includes:

[0048] A second telescopic member 410, having a second fixed end and a second telescopic end, the second telescopic end expanding and contracting along the second direction, and the second telescopic end is connected to the first fixed end;

[0049] A connecting member 420, connecting the first positioning member 320 and the second fixed end.

[0050] In this embodiment, the specific composition of the limiting component 400 is given. The limiting component 400 includes a second telescopic member 410. The second telescopic member 410 has a second fixed end and a second telescopic end. The second fixed end is firmly connected to the base 100, and the second telescopic end also expands and contracts along the second direction. The second telescopic member 410 can be a spring buffer or a similar structure. The second telescopic end of the second telescopic member 410 is connected to the first fixed end. The limiting component 400 further includes a connecting member 420. The connecting member 420 plays a bridging role. The connecting member 420 connects the first positioning member 320 and the second fixed end. In this way, when the first telescopic member 310 expands and contracts, the second telescopic member 410 expands and contracts synchronously. The two can limit and support each other to ensure the accurate positioning of the battery cell in the second direction. In addition, the second telescopic member 410 can be a spring buffer. In this way, the second telescopic member 410 can absorb the impact when the second positioning component 300 clamps the battery cell, effectively protecting the battery cell from damage.

[0051] As Figure 2 , in an embodiment of the present utility model, the first positioning component 200 includes:

[0052] There are two second positioning members 210, and the two second positioning members 210 are arranged on opposite sides of the workbench along the first direction;

There are two second positioning members 210, which are respectively arranged on opposite sides of the workbench along the first direction. When clamping the battery cell, the two second positioning members 210 are in close contact with the side surface of the battery cell; the third telescopic member 220 is installed on the base 100 and is drivingly connected to the two second positioning members 210. The third telescopic member 220 can drive the two second positioning members 210 to approach or move away from each other, thereby realizing the positioning of the battery cell in the first direction. In order to simplify the structure, the third telescopic member 220 can adopt a double-acting cylinder structure; when it is necessary to pick up and place the battery cell, the two second positioning members 210 move away from each other to create space for the picking up and placing of the battery cell. When positioning, the third telescopic member 220 drives the two second positioning members 210 to approach each other to clamp the battery cell, realizing the positioning of the battery cell in the first direction.

[0055] Such as Figure 2 , in an embodiment of the present utility model, the battery cell positioning fixture further includes a slide rail assembly 500.

The slide rail can be fixed on the base 100 and extends along the first direction. There are two sliders, and the two sliders are respectively slidably connected to the slide rail. The two second positioning members 210 are respectively connected to the two sliders. In this way, a sliding connection is established between the two second positioning members 210 and the base 100, which can provide guidance for the movement of the two second positioning members 210 in the first direction and ensure the positioning accuracy of the battery cell.

They can deform appropriately according to the size and shape of the battery cell, absorb the impact energy during positioning, and reduce the damage that may be caused to the battery cell by hard contact.

[0057] Such as Figure 1, in an embodiment of the present utility model, the base 100 includes:

[0058] A fixing plate 110 having a connecting end face;
