Technical Field

[0001] The present invention relates to the technical field of automated storage and transportation of battery cells, and in particular to a multi-product multi-liquid injection and transportation device and a control method thereof. Background Art

[0002] During the production of lithium batteries, the traditional method usually follows the process of primary liquid injection - high-temperature immersion storage - formation - secondary liquid injection. However, after years of updates and iterations of product processes, the traditional method can no longer meet the requirements of new products. In the past, the primary and secondary liquid injections were placed in different areas according to the process sequence. If two products were produced at the same time, a complete set of system equipment needed to be purchased and placed in other areas. This not only resulted in a waste of energy and human resources, but also increased equipment costs. Summary of the Invention
