Cold- and hot-press fixture formation capacity division machine of soft pack lithium battery

Abstract

A cold- and hot-press fixture formation capacity division machine of a soft pack lithium battery comprises a plurality of sets of capacity division devices and maintenance units, wherein the maintenance units are used for connecting the capacity division devices, the capacity division devices are laminated to form a layered structure and are maintained in axial parallel, the maintenance units arearranged on side surfaces of the capacity division devices, and each capacity division device comprises an outer frame, a hot-press formation capacity division hot-press fixture unit, a cold-press formation fixture unit, a charge-discharge formation control unit, a battery loading and unloading unit, a transplant manipulator unit, a production flow control detection and safety warning unit, a central controller and a database unit. The cold- and hot-press fixture formation capacity division machine has the beneficial effects that battery carrying, turnover, pressurization, warning, formation,capacity division, cooling and formation are integratedly performed by a set of system, the production efficiency is improved, the battery consistency is ensured, and the battery production cost is reduced; and with the adoption of a standard and modular design mode, random assembly and lamination can be performed, and customized automatic assembly line is achieved.

Description

Technical field [0001] The invention relates to a soft-packed lithium battery cold and hot pressing clamping device for composing, belonging to the technical field of soft-packed lithium battery manufacturing equipment. Background technique [0002] In the production process of soft-pack lithium batteries, formation, volume division, hot pressing and cold pressing are important processes that determine the quality of the lithium battery after it is formed. Formation is to activate the internal activity of the lithium battery to ensure that it has good charge and discharge performance and cycle life. Volume division is the most basic and most important process for determining the consistency of the battery. The original process leads to the production cycle Very long, the use of new heating and pressurizing formation and volumetric methods can effectively reduce production time and improve the consistency of battery performance and quality. [0003] In the original soft-packed lith...

AI Technical Summary

Problems solved by technology

[0003] In the original soft-pack lithium battery production equipment and process, the hot-press formation, capacity separation process, and cold-press setting of the lithium battery are implemented separately, which requires various equipment or fixtures, including supporting separate loading and unloading equipment. , divided into four processes for manufacturing, so the workload of manual handling operations is large, the production efficiency is also very low, the investment in equipment is large, and the floor area is large
