Technical Field

The invention relates to the technical field of battery cell drying equipment; in particular to a vacuum drying furnace for automatically baking an electric core.

Background

In the production process of the lithium battery, a drying process is required to be carried out on the lithium ion battery core, the lithium ion battery core is fed into the heating cavity, the battery core is firstly fed to the heating cavity accessory through various clamps, then the cavity is opened through a device similar to a hinge on the cavity, and finally the battery core is fed into the cavity. The vacuum drying process of the existing equipment adopts an annular assembly line, a feeding trolley runs on an annular track, a battery cell heating plate is arranged on the trolley, and after the clamp feeds the battery cell heating plate with good materials (battery cells), the battery cell heating plate moves along with the trolley to enter a heating drying cavity. Therefore, in the whole working process, the trolley needs to repeatedly enter and exit the heating and drying cavity, a large amount of heat exchange is brought, resource waste is caused, and after entering the heating and drying cavity each time, the trolley needs to be closed and heated with the contact in the heating and drying cavity, and the contact is separated when the drying is completed. Therefore, the trolley and the heating and drying cavity contact can be repeatedly closed and opened, and the contact can be failed or disabled as working time is accumulated. The trolley needs to be sealed after entering the heating and drying cavity, and the trolley enters and exits from two sides, so that the sealing of the heating and drying cavity has strict requirements, and the cost is greatly increased. Meanwhile, the trolley brings the heating plate and the battery core into and out of the heating cavity together, and the problem that the position of the battery core changes in the process of feeding the battery core into the heating cavity exists.
