Description

TECHNICAL FIELD

[0001] The present application relates to a soft package lithium battery forming equipment, in particular to a soft package lithium battery multifunctional high-precision forming equipment. BACKGROUND

[0002] Lithium battery is a kind of battery with lithium metal or lithium alloy as positive / negative electrode material and using non-aqueous electrolyte solution, which is widely used in mobile phones, tablets and other electronic devices. In the production process of lithium battery, the lithium battery needs to be packaged, and after packaging, the outside of the lithium battery needs to be shaped to meet the production and practical requirements. In the shaping process, multiple processes such as edge cutting, angle cutting, corner folding, angle pressing, bending, shaping, reversing, detection, positioning and gluing, curing, edge folding, hot pressing and cold pressing are required. Since the steps of lithium battery shaping are numerous, the current processing is carried out by separate equipment, which is extremely low in efficiency, and each process is carried out independently, which is easy to cause part of the process to be repeated or omitted, and cannot guarantee the quality of the lithium battery. Therefore, it is necessary to make an automatic equipment to concentrate all the shaping processes required by the lithium battery on the same equipment, and to carry out the processes in sequence on the automatic equipment to improve the efficiency of lithium battery shaping and ensure the stability of shaping.
