Description

Technical Field

[0001] The utility model relates to the technical field of battery drying, in particular to a lithium battery vacuum drying box with a fast loading and unloading structure. Background Art

[0002] Lithium battery vacuum drying oven, also known as vacuum oven, vacuum baking oven, vacuum oven, etc., is an advanced drying equipment designed for lithium battery production lines. It can quickly and efficiently dry lithium battery materials under vacuum, with the advantages of fast drying speed, low pollution, and no damage to the material structure. This technology is widely used in chemical, electronic, biological, food, pharmaceutical, health and light industry fields, especially in the production process of lithium batteries, it plays a vital role in ensuring battery performance, improving production efficiency and product quality.

[0003] In the process of drying lithium battery materials, the loading and unloading method of traditional drying ovens has become a bottleneck that cannot be ignored. Specifically, when lithium battery materials need to be dried, operators or automated equipment need to take out the trays containing the materials from the drying oven layer by layer in a predetermined order. When drying is completed or new materials are ready to be placed, the trays are put back layer by layer. This loading and unloading method of taking out and putting in layer by layer is not only cumbersome to operate, but also greatly affects production efficiency and process smoothness.

[0005] Although the device in the above document can drive the nitrogen inside the drying chamber to circulate heat flow through the circulating fan, thereby ensuring the drying efficiency of the drying chamber, when loading and unloading materials, the device in the above document needs to remove the lithium battery materials from the placement plate one by one, and then place new lithium battery materials on the placement plate one by one, which causes the device in the above document to be slow when loading and unloading materials and have low efficiency.
