[0002] Vacuum baking and dehumidifying is a very key procedure in battery production, and most of vacuum baking and dehumidifying needs to be completed by vacuum oven. The quality of vacuum oven will directly affect the quality of battery. If the vacuum degree does not reach the set requirement during vacuum baking and dehumidifying, or the temperature is not uniform during vacuum baking and dehumidifying, the water content in the electrolyte of battery pole piece will not meet the standard. Water has a great influence on the performance of battery, including voltage, internal resistance, self-discharge and other indicators. Excessive water content will lead to product scrap and quality decline. Therefore, in multiple production procedures of battery, positive and negative pole pieces, battery cell and battery are subjected to multiple vacuum baking and dehumidifying to remove water as much as possible. Therefore, battery must be subjected to vacuum baking and dehumidifying before liquid injection and sealing. The purpose is to dehumidify. The means of vacuum environment is because the boiling point of water is significantly reduced under negative pressure. The theoretical boiling point is as low as 45℃ at-0.089Mpa. This is obviously more conducive to dehumidification. In the prior art, battery materials are usually placed in batches in the oven by using trays. During the feeding process, if the trays are not placed in place, the baking quality will be affected.
