Abstract

The invention discloses an automatic coating control method and an automatic coating control system. The automatic coating control system comprises a coating production line control system, a data transmission network, a coating steel roller, a double-side-penetrating beta sensor, a coating cavity, a pressure detection sensor, a feeding tank, a feeding pump, a feeding pipeline, a coating pipeline and a drying box. The coating production line allows a battery pole piece to pass, the coating production line control system controls production, the battery pole piece is produced through the coating cavity, the coating steel roller and the drying box, the pressure detection sensor is mounted on the coating cavity, data after detection are transmitted to the coating production line control system through the data transmission network after the double-side-penetrating beta sensor is mounted on the drying box, and the feeding tank feeds slurry to the coating cavity through the feeding pump and the feeding pipeline. The automatic coating control system is simple in structure and reasonable in design, slurry feeding quantity in the process of manual intervening and adjusting of coating is reduced, and automatic adjusting is realized; lag of surface density adjusting in the process of coating is reduced.

Description

technical field [0001] The invention relates to the field of battery manufacturing, in particular to an automatic control coating method and a control system. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. The earliest lithium battery came from the great inventor Edison, using the following reaction: Li+MnO2=LiMnO2 This reaction is a redox reaction, discharge. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now. [0003] Lithium battery refers to the most basic electrochemical unit of lithium, including metal lithium, lithium alloy, lithium ion and lithium polymer. Lithium...
