Roof membrane pressing machine of lithium thionyl chloride battery

Abstract

The invention relates to a roof membrane pressing machine of a lithium thionyl chloride battery, comprising a working platform; the working platform is provided with a roof membrane feeding mechanism, a battery steel-shell assembly feeding mechanism, a punching mechanism and a pressing mechanism in sequence, wherein the roof membrane feeding mechanism is used for conveying a roof membrane to a pressing work position; the battery steel-shell assembly feeding mechanism is used for conveying a battery steel-shell assembly to the pressing work position; the punching mechanism is used for punchingthe roof membrane; the pressing mechanism is used for pressing the roof membrane into the battery steel-shell assembly; and the roof membrane feeding mechanism, the battery steel-shell assembly feeding mechanism, the punching mechanism and the pressing mechanism are connected with a main control circuit. In the roof membrane pressing machine, the structural design is reasonable, automatic feedingand pressing of the roof membrane and the battery steel-shell assembly are realized, and the problems of low reject ratio of products, low production efficiency and incapability of monitoring the quality because procedures of manual cutting, removing of static electricity, installation into a battery, and shaping and the like are eliminated when the roof membrane is assembled are solved. The roofmembrane pressing machine has the characteristics of high assembling speed and good quality; and the production cost is greatly saved, and the operating environment of workers is improved and the production efficiency is increased.

Description

technical field [0001] The invention relates to a machining device, in particular to an automatic feeding and pressing-in automation of battery steel shell components with bottom film, edge film, tetrafluoroethylene and carbon beads pressed into the top cover film and steel shell equipment. Background technique [0002] Column lithium thionyl chloride battery (hereinafter referred to as lithium sub-battery) is widely used in electric tools and electric vehicles due to its advantages of high working voltage, small size, light weight, high energy, no pollution, small self-discharge, and long service life. , military equipment, aerospace and other fields. With the growth of social demand and the increasing difficulty of lithium-sub-battery manufacturing process, enterprises put forward higher requirements for the production of lithium-sub-battery. The structure of the lithium sub-battery includes the battery top cover assembly and the battery steel case assembly. The battery ...

AI Technical Summary

Problems solved by technology

[0003] At present, the feeding of the top cover film is mainly manual feeding, which has the disadvantages of safety hazards and low efficiency; the forming of the top cover film mainly depends on manual cutting, which has low production efficiency and high defective products; and the pressing of the top cover film is mainly Manual operation leads to poor product quality, high labor costs and low production efficiency, which reduces the market competitiveness of enterprises
