Problems solved by technology

[0004] Existing chemical negative pressure technology generally controls the negative pressure system in the form of a vacuum proportional valve, which can be adjusted steplessly through software to meet the production process standards of lithium batteries. The continuous production capacity of the line, the proportional valve will have the problem of blockage if the valve is not used for a long time
At the same time, the proportional valve has the problem that it is not easy to disassemble, so it can only be replaced with a new one, which leads to a lot of time and cost for maintenance, and the overall cost increases

Description

technical field [0001] The invention belongs to the technical field of lithium battery formation equipment, and in particular relates to a negative pressure vacuum control system for battery formation equipment and an automatic control method thereof. Background technique [0002] Formation is a chemical and electrochemical reaction process in which the raw plate is transformed into a charged state by charging in the electrolyte, removing impurities, and improving the electrochemical activity of its active materials. Formation includes different methods such as external tank formation and battery internal formation, and is one of the important processes in the production of lead-acid, cadmium / nickel and other batteries. [0003] Standing the assembled steel-cased battery directly will cause corrosion inside the steel case, while aluminum-cased and pouch batteries need to be preformed and vented before sealing, otherwise serious flatulence problems will occur, and negative pr...
