Description

Technical Field

[0001] The present application relates to the technical field of lithium battery manufacturing, and in particular to a lithium battery equipped with a material unloading and caching station. Background Art

[0002] With the rapid development of electric vehicles, smart devices and other fields, lithium batteries, as a core energy source, are receiving more and more attention from the industry for their production efficiency and product quality. The production station of lithium batteries is mainly responsible for receiving battery cells that have completed preliminary processing from upstream processes (such as winding, film making, etc.) and temporarily storing them, waiting for subsequent processes (such as assembly, formation, etc.). The design of the unloading buffer station must not only ensure the safe storage of battery cells, but also take into account the overall layout of the production line and the smoothness of the process flow.

[0003] In the prior art, when the battery cells on the buffer station do not circulate for a long time, the internal temperature drops and the core temperature decreases. This temperature drop will have two adverse effects: first, the battery cells with low temperature may not be fully compacted during the hot pressing process, resulting in internal electrode breakage, powder loss and other problems, which not only affects the external coating and shelling process of the battery cells, but also may pose a risk to the safety performance of the battery cells; secondly, when the battery cell temperature is lower than the lower limit set by the process, manual re-processing is usually required, which not only increases the workload of manual operation, but also affects the production efficiency of the equipment, so it needs to be improved.
