Soft package lithium battery hot and cold pressed fixture formation automatic production line

Abstract

The invention relates to a soft package lithium battery hot and cold pressed fixture formation automatic production line, which consists of a rack, hot press fixture formation units, a cold press shaping fixture unit, charge-discharge formation control units, a battery loading and unloading unit, a transplanting manipulator unit, a production process control and detection unit, a safety alarming unit and a controller. The hot press fixture formation units and the charge-discharge formation control units are both disposed on the surface of the rack along an axial direction, each set of hot press fixture formation unit corresponds to a set of charge-discharge formation control unit, and the moving range of the transplanting manipulator unit covers the whole processing station. The production process control and detection unit, the safety alarming unit and the central controller are all mounted on the rack. According to the invention, battery turnover, pressurization, heating, formation, cooling forming and data acquisition are integrated in one set of system to proceed, the transit process between procedures is reduced, the orginal two procedures are combined into one, the production efficiency is improved, the battery consistency is ensured, and an automatic assembly line is realized.

Description

technical field [0001] The invention relates to an automatic production line for cold and hot pressing fixtures of soft-pack lithium batteries. Background technique [0002] In the production process of soft-pack lithium batteries, formation, hot pressing, and cold pressing are three important processes in the forming process of lithium batteries. Formation is to activate the internal activity of lithium batteries to ensure good charge-discharge performance and cycle life. Hot-press fixture formation can improve the above-mentioned performance of soft-pack lithium batteries more significantly, and cold-press forming has a better effect on battery appearance. [0003] In the existing soft-pack lithium battery production equipment and processes, the hot-press formation and cold-press setting of lithium batteries are implemented separately, which requires different equipment or fixtures and tooling, and is divided into three processes for manufacturing, so manual handling The ...
