[0007] Furthermore, the aforementioned clamping unit also includes a second double-headed cylinder and a second L-shaped claw. The mounting base is fixedly provided with the second double-headed telescopic cylinder in a front-to-back orientation. The two piston rods of the second double-headed telescopic cylinder are both fixedly provided with a second connecting seat. The second connecting seat is provided with a second L-shaped claw, which is used to abut against the lower end face of the chip.

[0008] Furthermore, the second connecting seat is provided with a second slider that can slide up and down, and is equipped with a second compression spring that moves the second slider up and down; the second L-shaped claw is fixedly provided with the first slider.

[0009] Furthermore, it also includes a frame, a two-dimensional electric slide, and a mounting plate. The frame is movably mounted with the mounting plate via the two-dimensional electric slide, and the mounting plate is provided with at least one gripping unit.

[0010] Furthermore, the aforementioned two-dimensional electric slide table includes a horizontal sliding module, which has two slide tables. Each slide table is equipped with a lifting sliding module, and each lifting sliding module has a mounting plate fixed on its slide table.

[0011] Furthermore, each mounting plate is equipped with two gripping units.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] Firstly, in this utility model, a gripper unit is specially designed for the shape characteristics of the battery cell.

[0019] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of this utility model; however, those skilled in the art can implement this utility model without these details.

[0020] like Figure 1 and Figure 2 As shown, a mechanical gripper for battery cells has at least one gripping unit 4. In one specific embodiment, the mechanical gripper has four gripping units 4, which are arranged in pairs.

[0021] like Figures 1-3 As shown, the mechanical gripper includes a frame 1, a two-dimensional electric slide 2, a mounting plate 3, and gripping units 4. The frame 1 is movably mounted with two mounting plates 3 via the two-dimensional electric slide 2, each mounting plate having two gripping units 4. Specifically, the two-dimensional electric slide 2 includes a horizontal sliding module 21. This horizontal sliding module 21 has two slides, each slide having a lifting sliding module 22. Each lifting sliding module 22 has a mounting plate 3 fixedly mounted on its slide, and each mounting plate 3 has two gripping units 4 arranged horizontally. The horizontal sliding module 21 and the lifting sliding module 22 are existing linear sliding modules, and their specific structures will not be described in detail here.

[0022] like Figures 1-3 As shown, specifically, the clamping unit 4 includes a mounting base 41, a first double-headed cylinder 42, a first connecting base 43, a first L-shaped claw 44, a first cylinder 45, a pressure plate 46, a second double-headed cylinder 47, a second connecting base 48, and a second L-shaped claw 49. The mounting base 41 is fixedly mounted with the first double-headed telescopic cylinder 42 facing left and right. Both piston rods of the first double-headed telescopic cylinder 42 are fixedly mounted with the first connecting base 43. The first connecting base 43 is provided with the first L-shaped claw 44, and the pressure plate 46 is movably mounted on the first connecting base 43 via the first cylinder 45. The first L-shaped claw 44 abuts against the lower end face of chip a, and the pressure plate 46 abuts against the upper end face of the chip. The pressure plate 46 and the first L-shaped claw 44 are vertically opposed to each other to facilitate clamping chip a. The mounting base 41 is also fixedly provided with a second double-headed telescopic cylinder 47 in a front-back orientation. The two piston rods of the second double-headed telescopic cylinder 47 are both fixedly provided with a second connecting seat 48. The second connecting seat 48 is provided with a second L-shaped claw 49, which is used to abut against the lower end face of chip a.

[0023] like Figures 1-3 As shown, preferably, the first connecting seat 43 is slidably provided with a first slider 432 and is equipped with a first compression spring 431 that moves the first slider 432 up and down. The first cylinder 45 and the first L-shaped claw 44 are respectively fixed to both sides of the first slider 432, thereby allowing the first cylinder 45 and the first L-shaped claw 44 to float up and down on the first connecting seat 43. Furthermore, the second connecting seat 48 is slidably provided with a second slider 482 and is equipped with a second compression spring 481 that moves the second slider 482 up and down. The second L-shaped claw 49 is fixed to the first slider 432, thereby allowing the second L-shaped claw 49 to float up and down on the second connecting seat 48. This design avoids direct hard contact between the mechanical gripper and the fixture, tray, or other carrier when it moves down during the process of picking up and discharging the battery cell a, thus providing excellent protection for the mechanical gripper, fixture, and battery cell a.

[0024] like Figures 1-3 As shown, during use, the first L-shaped claws 44 on the left and right sides and the pressure plate 46 can quickly and stably grip the left and right sides of the battery cell a, while the second L-shaped claws on the front and rear sides can lift the middle of the battery cell from the front and rear sides to prevent the battery cell from deforming, while avoiding the tab a1, and finally realize the automatic gripping of the battery cell a.

[0025] This is merely a specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be considered as an infringement of the protection scope of the present utility model.
