Description

A battery vacuum drying automatic production line

technical field

The invention relates to automatic battery baking and drying equipment, in particular to an automatic battery vacuum drying production line.

Background technique

The current lithium-ion batteries have developed rapidly due to their advantages of high energy density, high voltage, and no pollution to the environment. In the battery production process, before the battery is filled with electrolyte, the battery must be transported to a drying box for baking and drying to reduce the moisture content of the battery cells and avoid side reactions between the electrolyte and water after the injection. , affecting the cycle performance and safety of the battery.

During the baking and drying process of the battery, most of the operations are done manually, which not only has low efficiency, but also does not guarantee the drying quality. Moreover, the number of batteries that can be accommodated in the existing drying box is relatively small, and only batches of batteries can be baked and dried, or the number of vacuum ovens can be increased to meet production requirements. However, the batch baking and drying method requires a small number of batteries to be baked and dried each time, which results in low efficiency and long drying time, and is prone to misplacement during transportation and loading of batteries, which affects the drying effect. The use of increasing the number of vacuum ovens can solve the problem of insufficient drying capacity of batteries.
