[0002] The current battery cell group includes a plurality of battery cells arranged in an array, and a flexible insulating barrier is provided between two adjacent battery cells; the existing method of placing the battery cell group into the battery box is as follows: a robot grips the battery cell group, thereby transferring the battery cell group into the battery box, and then another robot is required to insert a clamping plate between one side of the battery cell group and the side wall of the battery box, thereby maintaining the close arrangement of the battery cells of the battery cell group in the battery box. The existing assembly method requires at least two robots for assembly, and the battery cell group needs to be loaded and the clamping plate needs to be inserted in steps, resulting in low assembly efficiency and not conducive to saving assembly costs.

[0040] Embodiment 1

[0041] The embodiment of the utility model provides an assembly robot, which can effectively improve the assembly efficiency of assembling a battery cell group into a battery box and can help reduce the assembly cost.

[0042] Please refer to the attached Figures 1 to 4 The assembly robot is used to assemble the battery cells into the battery box, and includes: a clamping drive device 1; a first clamping arm 2 and a second clamping arm 3 arranged opposite to each other, which are driven towards each other by the clamping drive device 1 to clamp and squeeze the battery cell group; a pressing device 4, which is arranged between the first clamping arm 2 and the second clamping arm 3 and is used to push the squeezed battery cell group into the battery box.

[0043] The existing battery cell group includes a plurality of battery cells arranged in an array, and a flexible insulating barrier is provided between two adjacent battery cells. When the battery cell group is not squeezed, the flexible insulating barrier is in a stretched state, resulting in a slightly larger distance between two adjacent battery cells, so that the entire battery cell group cannot be directly loaded into the battery box. Therefore, in the actual installation process, the first clamping arm 2 and the second clamping arm 3 are driven by the clamping drive device 1 to clamp and squeeze the battery cell group, so that each layer of the flexible insulating barrier in the battery cell group is flattened, thereby compressing the total length of the battery cell group, so that the battery cell group can be directly pressed into the battery box by the pressing device 4. It should be supplemented that after the first clamping arm 2 and the second clamping arm 3 clamp and compress the battery cell group, the clamped battery cell group needs to be transferred to the top of the battery box, and then the pressing device 4 presses the battery cell group into the battery box. It should also be noted that if the total length of the battery cell group is less than the total length of the battery box opening, the battery cell group can be directly pressed into the battery box; or, if the total length of the battery cell group is less than a preset length, the battery cell group can be slowly pressed into the battery box by the pressing device under the action of a guide ramp or other guiding structure.

[0044] It should be particularly noted that the clamping drive device 1 can also drive the first clamping arm 2 and the second clamping arm 3 to move away from each other to loosen the battery cell pack so that the battery pack can better enter the battery box.

[0045] Optionally, the pressing device 4 includes a pressing plate 41 for pressing the battery cell group and a pressing driving device for driving the pressing plate 41 to move up and down along a set direction, and the driving end of the pressing driving device is fixedly connected to the pressing plate 41. The pressing driving device drives the pressing plate 41 to move downward, thereby applying pressure to the battery cell group so that the battery cell group is pressed into the battery box.

[0046] Optionally, at least two flexible buffer strips 42 are arranged at intervals on the bottom side of the lower pressing plate 41 near the battery cell group. The flexible buffer strip 42 is a strip structure made of a flexible material, which mainly has a buffering effect. The lower pressing plate 41 applies pressure to the battery cell group through the flexible buffer strip 42 to avoid crushing the battery cell group or pressing defects such as scratches on the battery cell group.

[0047] Optionally, a gap 401 for avoiding the explosion-proof valve or the pole is provided between two adjacent flexible buffer strips 42. That is, the provision of the flexible buffer strip 42 can also avoid damaging the explosion-proof valve of the battery cell or the pole.

[0048] Optionally, the pressing drive device includes a telescopic shaft 43, and the end of the telescopic shaft 43 is connected to the lower pressing plate 41; the clamping drive device 1 is provided with a through hole for the telescopic shaft 43 to pass through. The telescopic shaft can drive the lower pressing plate 41 to move up and down. The telescopic shaft is extended and retracted from the through hole, and moves with the clamping drive device 1, thereby ensuring that the battery cell group can be accurately pressed down.

[0049] Optionally, the first clamping arm 2 includes a first clamping portion 21, and the second clamping arm 3 includes a second clamping portion 31; the lower pressing plate 41 has a set length, and the first clamping portion 21 and the second clamping portion 31 approach each other to compress the battery cell group, so that the total length of the compressed battery cell group is equal to the set length of the lower pressing plate, and at this time, the first clamping portion 21 and the second clamping portion 31 are respectively abutted against the two opposite ends of the lower pressing plate 41. Specifically, the lower pressing plate 41 is equivalent to a positioning plate constituting a positioning first clamping portion 21 and a second clamping portion 31, so as to effectively avoid applying excessive pressure to the battery cell group and effectively avoid pinching the battery cell group. In addition, the set length is a preset length and can be adjusted according to actual conditions.

[0050] Optionally, the first clamping portion 21 and the second clamping portion 31 are both provided with a stopper 22 for positioning and stopping the lower pressing plate 41. This prevents the lower pressing plate 41 from directly hitting the driving body 11 during the ascending process, thereby reducing the possibility of damage to the driving body 11.

[0051] Optionally, the clamping drive device 1 includes a driving body 11 and a driving rod 12 ; the driving body 11 drives the first clamping arm 2 and the second clamping arm 3 to slide toward each other or slide away from each other through the driving rod 12 .

[0052] Optionally, the first clamping surface of the first clamping arm 2 for clamping the battery cell group and the second clamping surface of the second clamping arm 3 for clamping the battery cell group are parallel to each other, and the lower pressing plate 41 is perpendicular to the first clamping surface. Specifically, the first clamping arm 2 contacts one side of the battery cell group through the first clamping surface, and the second clamping arm 3 contacts the other side of the battery cell group through the second clamping surface, and the first clamping arm 2 and the second clamping arm 3 approach each other, thereby clamping and squeezing the battery cell group.
