Baking oven device of matrix (copper foil or aluminum foil) suspension type coating machine

Abstract

The invention relates to a baking oven of a matrix (copper foil or aluminum foil) suspension type coating machine, which belongs to the lithium-ion battery manufacturing equipment, part of the coating machine, and is used for drying slurry coated on a matrix. The domestic baking oven of the coating machine is generally supported by support rods at present, and the interval between two support rods is about 0.3-0.5 meter. The number of required support rods increases along with increase in the length of the baking oven of the coating machine, the friction of the support rods to the matrix (aluminum foil or copper foil) correspondingly increases, and the matrix (aluminum foil or copper foil) can easily produce scars, creases and other defects, thereby seriously affecting the product quality. In the key technical scheme to solve the problems, the baking oven device of the matrix (aluminum foil or copper foil) suspension type coating machine comprises a baking oven body (with an outer baking oven shell, an inner baking oven core, a baking oven door and a baking oven rack), a ship-shaped independent air intake chamber, an improved air nozzle, a drying chamber, an exhaust chamber, a circulating air chamber, a circulating air duct, an air blower, a heating device and the like, and is characterized in that wind force in the baking oven of the coating machine is used for supporting the matrix, so that the matrix is in a suspended state in the baking oven. Due to the matrix suspension type structure, the invention solves the problem of friction of the support rods to the matrix in the baking oven of the coating machine, and facilitates the improvement of the quality of the coated product, the increase of the length of the baking oven so as to speed up the coating, the enhancement of the production efficiency and the like.

Description

technical field [0001] The invention relates to a lithium ion battery coating machine, in particular to a substrate (copper foil or aluminum foil) suspension coating machine oven device. Background technique [0002] Coating is an indispensable process in the production process of lithium-ion batteries, and it is also a key process that directly affects various performances such as battery safety, capacity, and consistency. [0003] Coating is to apply the prepared paste-like viscous slurry evenly, continuously or intermittently on the substrate (aluminum foil or copper foil) to ensure the thickness consistency of each coating position and control the coating thickness. within the tolerance range required by the process. The coating machine oven is one of the components of the coating machine, which is a device for drying the slurry coated on the substrate. [0004] The ordinary coating machine oven is divided into the main body of the oven (including the inner and outer t...

AI Technical Summary

Problems solved by technology

Therefore, the longer the length of the coating machine oven, the more support rods it needs, and the greater the friction generated by the support rods on the substrate (aluminum foil or copper foil), the greater the friction, the substrate (aluminum foil) or copper foil) are prone to defects such as scars and wrinkles, which seriously affect product quality
