The previous feeding devices are difficult to feed the closely arranged battery cells and can only perform manual feeding or automatic feeding after manual transfer. This not only slows down the feeding speed but also increases the labor intensity of workers. Summary of the Utility Model

[0039] The workpiece in the embodiments of the present application can be a battery cell, a battery or other workpieces.

[0040] The position adjusting component 2 can be an electric cylinder, a cylinder or a linear motor. Taking the cylinder as an example, one end of the cylinder is connected to one of the clamping components 1 to drive the clamping component 1 to move away from or close to the other clamping component 1, thereby adjusting the distance between the clamping components 1. The number of the position adjusting components 2 can be set according to the number of the clamping components 1, and the number of the position adjusting components 2 can be one less than the number of the clamping components 1.

[0041] The clamping member may include a clamping driving portion and a clamping plate.

[0043] The clamping device adjusts the distance between the clamping assemblies 1 through the position adjusting assembly 2 so that the distance between the clamping assemblies 1 conforms to the distance between the battery cells, facilitating the clamping of a single battery cell by the clamping assemblies 1. After the clamping assemblies 1 clamp the battery cells, the position adjusting assembly 2 adjusts the distance between the clamping assemblies 1 again so that the distance between the battery cells clamped by the clamping assemblies 1 conforms to the requirements of the next processing step. In this way, the feeding of the closely arranged battery cells can be realized, improving the working efficiency.

[0044] In addition, when the battery cells are arranged too closely, the telescopic suction member 11 can suck up the battery cells and then clamp the battery cells through two clamping members 12.
