[0029] Rack 1;

[0030] A base 10 is provided on the frame 1 and is rectangular in shape. A first positioning portion 21 and a second positioning portion 22 are respectively provided on adjacent first and second sides of the base 10;

[0031] Adjustment part: the first positioning part 21 and the second positioning part 22 are respectively provided with a first adjustment part 31 and a second adjustment part 32 at positions opposite to each other.

[0032] a first driving device, when the base 10 is provided with multiple first adjusting parts 31, and the first driving device drives the first adjusting parts 31 to slide toward the first positioning part 21;

[0033] The second driving device is provided in plurality and is used to respectively drive the second adjusting portion 32 to move toward the second positioning portion 22 .

[0034] In the actual design, the base 10 can be placed vertically or horizontally, and the four sides of the lithium battery are clamped by the relative movement of the first positioning part 21, the second positioning part 22, the first adjustment part 31 and the second adjustment part 32. At the same time, the second positioning part 22 is the reference edge for adjustment, preferably a narrow edge, and the simultaneous movement of multiple second adjustment parts 32 is achieved through the second driving device.

[0035] Specifically, the second positioning portion 22 and the second adjusting portion 32 are both detachable, thereby being applicable to lithium batteries of different sizes.

[0036] In the embodiment of the present invention, the length of the second positioning portion 22 is smaller than that of the first positioning portion 21 , ie, the second positioning portion 22 has a narrower side, thereby facilitating disassembly and installation.

[0037] Specifically, the base 10 is placed vertically or horizontally, thereby realizing lateral processing or vertical processing of the lithium battery, wherein the processing may be spraying or testing.

[0038] In an embodiment of the present invention, the base 10 is provided with at least two first ridges 41 extending along its length direction, the first positioning portion 21 and the second positioning portion 22 are respectively provided with second ridges 42, and the first adjustment portion 31 and the second adjustment portion 32 are provided with elastic contact portions 5.

[0039] Specifically, the elastic contact portion 5 includes a tube body 51 provided with an inner cavity and a positioning column 52 slidably installed in the inner cavity. An elastic member (such as a spring) is provided between the inner cavity and the positioning column, so that when clamping, the adjustment portion first elastically contacts the outer wall of the lithium battery, and then corrects its position and realizes point clamping.

[0040] In the embodiment of the present utility model, the frame 1 is provided with a base 6, and a first telescopic motor 61 is provided on the lower wall of the base 6. The first telescopic motor 61 is provided with a connecting arm extending forward, and the connecting arm is connected to the first adjusting portion 31.

The transverse guide rails are provided with transverse sliders 72 that are slidably arranged. The upper wall of the transverse slider is connected to the synchronous plate 7. The driving end of the second telescopic motor 62 is connected to the synchronous plate 7 and can drive it to slide transversely.

[0042] The second adjusting parts 32 are arranged at intervals on the synchronization plate 7, thereby achieving the compression and positioning of the lithium battery. At the same time, through reasonable layout, the space occupied by the positioning mechanism can be reduced, thereby making its volume smaller.

[0043] Specifically, a connecting portion 8 is provided between the connecting ends of the transverse slider and the synchronous plate 7, and a shielding arm 81 extends from both sides of the synchronous plate on the upper wall of the base 6. A shielding portion 82 is provided between the upper ends of the two shielding arms.
