Oven for baking big lithium ion battery pole piece rolls

Abstract

The invention discloses an oven for baking big lithium ion battery pole piece rolls. The oven comprises an oven body used for containing the big lithium ion battery pole piece rolls. The oven body is of a square structure. A front oven door and a rear oven door are arranged on the front side and the rear side of the oven body respectively. At least two driving gears are arranged at the bottom of the oven body. The driving gears are connected with a driving motor used for providing power for the driving gears. A conveyer belt is wound between the driving gears. The big lithium ion battery pole piece rolls are sequentially placed on pole piece supports in the oven body from the front oven door, the driving motor is controlled to operate so that the big lithium ion battery pole piece rolls can be conveyed into the oven body, and the big lithium ion battery pole piece rolls are sequentially conveyed out of the oven body from the rear oven door after baking is completed. According to the oven, a plurality of big lithium ion battery pole piece rolls can be baked at the same time, and the situations that the big lithium ion battery pole piece rolls need to be pushed into an oven manually one by one during baking and also need to be taken out of the oven manually one by one after baking is completed are effectively avoided; labor is saved, working efficiency is also improved, and the oven is suitable for line production.

Description

technical field [0001] The invention belongs to the technical field of lithium-ion battery manufacturing, and in particular relates to an oven for baking large rolls of pole pieces of lithium-ion batteries. Background technique [0002] Moisture control is very important in the manufacturing process of lithium-ion batteries, so it is necessary to bake the raw materials, bake the pole pieces, and bake the cells before liquid injection, so that the moisture content will not exceed the control value. [0003] For the pole piece, at present, when the coating is finished and baked, it is necessary to manually transfer the large roll of the first pole piece to the oven. When baking the second pole piece, it is necessary to manually push the first roll of pole piece into the oven. When baking the third pole piece, it is necessary to manually push the first and second pole pieces into the oven again. When baking the fourth pole piece, it is necessary to manually push the first, seco...
