[0029] As Figures 1 to 7 shown, a battery pack profiling gripper assembly of a preferred embodiment of the present invention includes a profiling gripper 10 and an end plate 40. The profiling gripper 10 includes a base 11, side clamping plates 15, side clamping arms 18, and a plurality of driving members 29 extending in a first direction. The plurality of driving members 29 are respectively connected to the base 11. Each side clamping arm 18 is in transmission connection with the corresponding driving member 29. The number of side clamping arms 18 is set corresponding to the number of driving members 29.

[0036] As one embodiment, the area of ​​the anti-slip film 43 is set to correspond to the area of ​​a side surface of the battery cell 50 facing the end plate 40 .

[0037] Further, such as Figures 1 to 3 As shown, the side clamp arm 18 includes a first end plate clamp arm 21, a second end plate clamp arm 24 and a plurality of battery cell clamp arms 26, the first end plate clamp arm 21, the second end plate clamp arm 24 and the battery cell clamp arm 26 are respectively connected to the driving member 29, and the plurality of battery cell clamp arms 26 are located between the first end plate clamp arm 21 and the second end plate clamp arm 24 in the second direction, the first end plate clamp arm 21 and the side clamp plate 15 form a first end plate clamping position 23, the second end plate clamp arm 24 and the side clamp plate 15 form a second end plate clamping position 25, and the end plate 40 is clamped at the first end plate clamping position 23 and the second end plate clamping position 25 respectively. The battery cell clamp arm 26 is used to clamp the battery cell 50, and the first end plate clamp arm 21 and the second end plate clamp arm 24 clamp the end plates 40 respectively, so as to realize the limitation of the battery cell clamping area 30.

[0038] Further, such as Figures 1 to 4 as well as Figure 7 As shown, the first end plate clamp arm 21 and the second end plate clamp arm 24 have the same structure, the first end plate clamp arm 21 is provided with a first clamping portion 22 on the side facing the end plate 40, the end plate 40 is provided with a second clamping portion 41 on the side facing the first end plate clamp arm 21, the first clamping portion 22 is clamped with the second clamping portion 41, the side of the side clamp plate 15 facing the end plate 40 is provided with a third clamping portion 17, the side of the end plate 40 facing the side clamp plate 15 is provided with a fourth clamping portion 42, the third clamping portion 17 is clamped with the fourth clamping portion 42.

The groove opening of the second clamping part 41 is arranged toward the first clamping part 22, and the groove opening of the fourth clamping part 42 is arranged toward the third clamping part 17, and the convex blocks are inserted into the grooves corresponding to the positions to achieve clamping. Of course, the first clamping part 22 and the third clamping part 17 are convex blocks, and the second clamping part 41 and the fourth clamping part 42 are grooves, which can also achieve the same technical effect.

[0040] As one embodiment, Figures 1 to 4 as well asFigure 7 As shown, the second clamping part 41 and the fourth clamping part 42 are wedge-shaped.

[0041] Furthermore, the base 11 is connected to the first sliding part 14, and the side clamping arm 18 is connected to the second sliding part 27. The first sliding part 14 and the second sliding part 27 are slidably connected in the first direction. By the sliding connection between the first sliding part 14 and the second sliding part 27, the movement track of the side clamping arm 18 is defined, and the movement stability of the side clamping arm 18 is improved.

[0042] Furthermore, as Figure 3 shown, the first sliding part 14 is a slide rail arranged in the first direction, and the second sliding part 27 is a slider.

[0045] Furthermore, as Figure 4 shown, the end plate 40 is provided with a first limiting convex block 44 and a second limiting convex block 45 for tying the tying belt. The first limiting convex block 44 and the second limiting convex block 45 are arranged at intervals.
