Polar plate drying equipment for lithium battery manufacturing

Abstract

The pole plate drying equipment for lithium battery manufacturing comprises a drying bin, a heat preservation layer is arranged on the inner wall of the drying bin, an electric heating pipe is arranged in the heat preservation layer, a bottom supporting plate is arranged in the drying bin in a sliding mode, a sealing plate is arranged on the bottom supporting plate, and a rotating assembly is arranged on the drying bin; the rotating assembly makes contact with the storage assembly on the bottom supporting plate and drives the storage assembly to rotate horizontally. According to the drying equipment, the contact and rotating storage assemblies are adopted, circulating and continuous horizontal rotating operation can be conducted on the positions and directions of the stored polar plates, the stored polar plates can make comprehensive and uniform contact with heat, the phenomenon of drying dead angles during polar plate drying is avoided, meanwhile, the contact area of the heat and the polar plates is increased, and the drying efficiency is improved. And the drying efficiency of the polar plate is effectively improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing, in particular to a plate drying equipment for lithium battery manufacturing. Background technique [0002] A device that converts chemical energy into electrical energy is called a chemical battery, generally referred to as a battery. After discharge, the internal active material can be regenerated by charging—the electrical energy is stored as chemical energy; when discharge is required, the chemical energy is converted into electrical energy again. The battery mainly includes the shell, positive plate, negative plate, separator and electrolyte. The production quality of the plate is very important to the overall quality of the battery in the later stage. During the production process of the battery, the plate needs to be dried to ensure that the lithium The battery plate can meet the subsequent installation and operation requirements.

Problems solved by technology

[0004] However, the installation angle and position of the pole plate in the existing drying device are relatively fixed, so that the contact area between the pole plate and the heat is also relatively fixed, and it is impossible to ensure that the pole plate can be in full and uniform contact with the heat, thus causing the pole plate to be prone to drying The phenomenon of dead angle reduces the effect of plate drying
