Description

Technical Field

[0001] The utility model relates to the field of lithium-ion battery pole group production, and more specifically, to a hot pressing and cold pressing device for a soft-pack lithium battery pole group. Background Art

[0002] With the continuous development of the global economy, the application scope of lithium-ion batteries has continued to expand, and has rapidly penetrated into all walks of life. As a result, the range of external dimensions of lithium-ion batteries has become increasingly larger. As the core component of lithium-ion batteries, the electrode group needs to be encapsulated in an aluminum-plastic shell after winding to prepare for subsequent liquid injection. After the electrode group is wound, the cross-section of the electrode group is elliptical, that is, the thickness of the middle part is much larger than the two side dimensions, and both dimensions exceed the external dimensions required by the process, especially for thicker electrode groups. This phenomenon is more prominent. The external dimensions of the electrode group have a very large impact on the packaging, and the packaging is directly related to the product quality and safety of the battery. Therefore, how to accurately control the external dimensions of the electrode group is a problem that needs to be solved urgently by those skilled in the art.

[0003] At present, new pole group winding machines are generally equipped with pole group hot pressing mechanisms. After the pole group is hot pressed, the thickness of the pole group will rebound slightly. Especially for pole groups with larger thickness, the size rebound is greater, exceeding the process requirements of the packaging. Production personnel are required to use a single hot press to perform a secondary hot pressing on the pole group offline to ensure that the thickness of the pole group is within the process requirements. There is also a way to maximize the control of the thickness of the pole group by increasing the hot pressing time, but the actual effect is not ideal. On the contrary, due to the increase in hot pressing time, the production efficiency of the equipment is reduced. In addition, there are still a large number of pole group winding machines in the industry that are not equipped with pole group hot pressing mechanisms. Production personnel are required to use a single hot press to hot press the pole group offline, which undoubtedly increases the battery production process and the workload of production personnel, resulting in an increase in battery production costs. How to ensure the hot pressing effect of the pole group, reduce the pole group production process, reduce the workload of personnel, and improve production efficiency is the problem to be solved by the present invention.
