AI Technical Summary
During the clamping process, the existing battery cell clamps are prone to damage or detachment of the battery cell due to dimensional tolerances, making it impossible to clamp stably.
The clamping jaws are equipped with airbags, which adapt to the size tolerance of the battery cells through the elasticity of the airbags. The airbag inflation volume is adjusted in real time in combination with the air circuit and control unit to achieve stable clamping.
It achieves safe and stable clamping that is not affected by the cell size tolerance, adapts to different cell sizes, and has a compact and reliable structure.

[0019] Figure 1 It is a schematic diagram showing the structure of the battery cell clamping device of the present invention.
[0020] like Figure 1 As shown, the battery cell clamping device 100 is used to grasp the battery cell 4, which has a clamping jaw 1, a clamping jaw driving mechanism 2 and an airbag 3. In this embodiment, the number of clamping jaws 1 is two, and the two clamping jaws 1 perform the action of grasping and releasing the battery cell 4. However, the number of clamping jaws 1 is not limited to this. As long as the grasping action can be performed, the number of clamping jaws 1 can be greater than two.
[0021] The jaw drive mechanism 2 is used to drive the two jaws 1 to perform gripping and releasing actions. In this embodiment, the jaw drive mechanism 2 is composed of a cylinder. However, the jaw drive mechanism 2 is not limited to this. As long as it can drive the jaws 1 to perform gripping and releasing actions, other driving methods can also be used, such as motor drive.
[0022] The airbag 3 is arranged on the inner side of each clamp 1 at a position for contacting the battery cell 4. In this embodiment, two airbags 3 are provided on each clamp 1. However, the number of airbags is not limited to this. For example, only one airbag 3 can be provided on each clamp 1, or more than three airbags 3 can be provided, as long as the battery cell 4 can be stably clamped.
[0023] In addition, although not shown, in this embodiment, the battery cell clamping device 100 further includes a control unit and an air path connected to each airbag 3. Preferably, the air path is provided in the clamping jaw 1, so that the overall structure of the device can be made compact.
[0024] By including a control unit and air circuit, the battery cell gripping device 100 can adjust the inflation volume of the airbag 3 in real time based on the size of the battery cell 4 through the control unit. For example, if the battery cell 4 is detected to be too large, the control unit will reduce the inflation volume of the airbag 3. If the battery cell 4 is detected to be too small, the control unit will increase the inflation volume of the airbag 3. In this way, the control unit can better adapt the airbag to the size of each battery cell.
[0025] The battery cell clamping device of the present invention has been described above, but the present invention is not limited to the above-mentioned embodiments and can be modified in various ways without departing from the main purpose of the present invention. For those skilled in the art, it is obvious that various omissions, changes and deformations can be made to the present invention without departing from the spirit or scope of the present invention. Therefore, it should be understood that the present invention includes changes and deformations within the scope of the accompanying claims and their equivalents. In particular, it should be understood that any combination of any part or all of any two or more of the above-mentioned embodiments and their variations can be understood to be within the scope of the present invention.
