The following embodiments are used to illustrate the present utility model but not to limit the scope of the present utility model.

[0037] As Figures 1 - 5 shown, the present utility model provides a battery cell off - line grouping rework tooling, which includes an installation platform. The installation platform includes a frame 100 and a bearing plate 200.

[0038] The frame 100 is composed of a frame body 101 and moving parts. The frame body 101 is a frame structure. The moving parts include four universal wheels 102, and the four universal wheels 102 are respectively installed at the four corners of the bottom of the frame body 101. In order to facilitate the pushing of the frame 100, a handle frame 103 is also provided on the frame body 101.

[0039] A rectangular bearing plate 200 is connected to the top surface of the frame body 101. A battery cell bracket 400 and a clamping seat 300 for supporting the battery cell bracket 400 are provided on the bearing plate 200.

[0040] In the present utility model, a total of three clamping seats 300 are provided. The three clamping seats 300 are arranged along the length direction of the bearing plate 200, and are perpendicularly connected to the upper surface of the bearing plate 200 in parallel and at intervals.

[0041] Each clamping seat 300 is a rectangular plate. One long side of each clamping seat 300 is perpendicularly connected to the upper surface of the bearing plate 200, and an opening groove 301 with an inclined surface is provided on the opposite long side. Specifically, the opening groove 301 is a right trapezoid with an opening relative to the clamping seat 300. The long waist side of the right trapezoid is the opening of the opening groove 301, which is located on the long side. The right waist of the right trapezoid is the bottom edge of the opening groove 301. The longer lower bottom edge of the right trapezoid is the first support inclined surface 3011 for supporting the bottom plate 401. A second support inclined surface 3012 parallel to the bottom edge of the opening groove 301 is also provided at the connection between the shorter upper bottom edge of the right trapezoid and the long side with an opening. The second support inclined surface 3012 is used to support the side baffle 404.

[0042] The above three opening grooves 301 are used to jointly clamp the battery cell bracket 400, and the battery cells to be reworked and assembled are placed on the battery cell bracket 400. In addition, to further stabilize the battery cell bracket 400, the connection between the battery cell bracket 400 and the opening groove 301 can be fixed with a fixing member.

[0043] The battery cell bracket 400 includes a bottom plate 401. One end of the bottom plate 401 along its length direction is fixedly connected with a first top plate 402, and the other end along its length direction is slidably connected with a second top plate 403. On one side edge of the bottom plate 401 along its length direction and between the first top plate 402 and the second top plate 403, a side baffle 404 is also connected. The side baffle 404 is arranged at a right angle to the bottom plate 401. In the present utility model, both the bottom plate 401 and the side baffle 404 are long rectangles. During actual use, the bottom surface of the battery cell is placed on the bottom plate 401, and one large surface of the battery cell is placed on the side baffle 404. The distance between the first top plate 402 and the second top plate 403 is the length dimension of the battery cell group or battery pack that can be accommodated.

[0044] To realize the sliding connection of the second top plate 403 to the bottom plate 401 so that the battery cell bracket 400 can be compatible with assembling battery cell groups or battery packs of different length dimensions, one side of the second top plate 403 is set as a long handle end. A strip-shaped avoidance groove 4041 is provided on the side baffle 404 along its length direction, and a linear module 500 is also provided on the side baffle 404.

[0045] The linear module 500 includes a handwheel 501, a lead screw 502, a lead screw nut, a guide rail 503, a slider, and a connection block 504.

[0046] The hand crank 501 has its fixed end connected to the side edge of the side baffle 404 and is arranged on the same side as the second top plate 403. The lead screw 502 is arranged on the bottom surface of the side baffle 404 and is parallel to one side edge of the avoidance groove 4041. One end of the lead screw 502 is connected to the driving end of the hand crank 501, and the other end thereof is rotatably connected to the bottom surface of the side baffle 404. A lead screw nut is connected to the lead screw 502. The guide rail 503 is arranged on the bottom surface of the side baffle 404 and is parallel to the other side of the avoidance groove 4041. A slider is connected to the guide rail 503. A connecting block 504 is fixedly connected to both the lead screw nut and the slider. The long handle end of the second top plate 403 passes through the avoidance groove 4041 and is connected to the connecting block 504.

[0047] To facilitate the operation of the linear module 500, the above bottom plate 401 is placed on the first support inclined surface 3011, and the side baffle 404 abuts against the second support inclined surface 3012. Moreover, a containing space is formed between the bottom surface of the side baffle 404 and the bottom edge of each of the above opening grooves 301. The lead screw 502 and the guide rail 503 are placed in this containing space.

[0048] Thus, when the hand crank 501 is manually rotated, the second top plate 403 can move synchronously along the avoidance groove 4041 in a direction close to or away from the first top plate 402, so as to realize adjusting the distance between the first top plate 402 and the second top plate 403 according to the length of the battery cell group or battery pack to be assembled. By further rotating the hand crank 501, the lateral pressing and fixing of the battery cell group or battery pack can also be realized. And when the battery cell bracket 400 is clamped on the card seat 300, the battery cell group or battery pack is placed at an acute angle relative to the bearing plate 200, which is more convenient for the handling, disassembly and assembly, and group assembly of the battery cell group or battery pack compared with the flat placement.

[0049] In addition, an anti-rotation fixing member 505 is also arranged on the lead screw 502. When, according to actual needs, the distance between the first top plate 402 and the second top plate 403 is adjusted by manually rotating the hand crank 501, the anti-rotation fixing member 505 is manually clamped to prevent the hand crank 501 from rotating. The anti-rotation fixing member 505 in the present utility model is a trapezoidal lead screw anti-rotation fixing member in the prior art.

[0050] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
