A Study of the Automatic Formation Line of Li-Ion Power Batteries
Li-ion battery is used widely in many industrial areas, and formation is a necessary process in battery manufacture. After formation, the performance of Li-ion power batteries can be activated. In the process of production, the key technology in the formation has been changed. The technology of formation and holding independently for each battery is turning into the formation after being clamped and then holding now. Therefore, the design of the automatic production line must base on the battery groups after being clamped. This text will introduce a new production line for the formation of Li-ion battery, mainly discuss the formation of clamped batteries, and how to realize the automation of the production line. The line uses the three-dimensional multi-layer frameworks, speed-fold chains and stoppers. The speed-fold chain is a new type of conveyor chain, and known as "flexible manufacturing unit". The battery groups can be stopped in the manufacturing line by the stoppers, and then they can be charged or discharged. The line can be connected by the lifting machine.
