Description

Technical Field

[0001] The utility model belongs to the technical field of battery cell production, and particularly relates to an adsorption device of a battery cell cutting and stacking machine. Background Art

[0002] A battery cell is a single electrochemical unit containing positive and negative electrodes, and is the energy storage part of a rechargeable battery. During production, multiple battery cells usually need to be stacked together, and the positive and negative electrodes of the battery cells are connected in series and parallel for use. When the battery cells are stacked and assembled, it is usually necessary to use suction cups to absorb the battery cells one by one and stack them together. There are many types of battery cells, including aluminum shell battery cells, soft-pack battery cells and cylindrical battery cells. The number of suction cups used and the installation position of the suction cups are different for different types.

[0003] For example, the document with the prior art publication number CN218841014U provides a battery cell transporting device and its adsorption mechanism, which includes a mounting plate and multiple adsorption components; each adsorption component includes a connecting plate, a guide rod, an upper spring, a lower spring, a suction plate and an elastic layer; the elastic layer is installed on the adsorption surface of the suction plate, and the suction plate of each adsorption component is configured to be connected to an air source for adsorbing a battery cell; the elastic layer of each adsorption component is used to generate deformation so that the battery cell fits on the adsorption component. This device is conducive to the fit between the suction plate surface and the battery cell surface, ensuring that the battery cell is at the same height after being lifted; the elastic layer makes the adsorption component fit more closely on the battery cell, which can prevent air leakage of the adsorption component.

[0004] For example, in the prior art described in the above-mentioned device, although the battery cells can be adsorbed, the adsorption direction of the suction plate is not easy to change, and the spacing between the suction nozzles is not easy to adjust, which makes it inconvenient to adjust the adsorption device according to different battery cell shapes and sizes. In view of this, we propose an adsorption device for a battery cell cutting and stacking machine. Utility Model Content
