Lithium battery cathode assembling machine

Abstract

The invention discloses a lithium battery cathode assembling machine which comprises a working platform, wherein a steel shell feeding device, a lithium sheet feeding and shearing device, a lithium sheet transferring device, a cathode shaping device, a steel shell transferring device and a cathode rolling device are sequentially arranged on the working platform, and all the devices are connected with a main control circuit. The invention solves the problems of low speed and low efficiency for manually assembling the cathode of a lithium battery, has the advantages of good assembling quality and high efficiency, improves the operating environment, and saves the cost. The lithium battery cathode assembling machine has a simple structure; when the cathode is assembled, the lithium sheet is firstly fed, and then sheared; the sheared lithium sheet is fed into a shaping working station, and subjected to low shaping, left and right shaping and upper shaping, and then loaded into a steel shell; and the steel shell loaded with the cathode is fed to a rolling position for rolling, and then the steel shell subjected to the rolling is conveyed and discharged, therefore, the automatic feeding,shaping and assembling of the lithium battery cathode are realized.

Description

technical field [0001] The invention relates to the technical field of lithium battery preparation, in particular to the preparation of lithium battery negative electrodes, in particular to a lithium battery negative electrode assembly machine with automatic material feeding, shaping and assembly. 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. Due to high working voltage, small size, light weight, high energy, no pollution, small self-discharge, and long cycle life, lithium batteries are widely used in power tools, electric vehicles, military equipment, aerospace and other fields. With the growth of social demand and the easy oxidation of lithium battery anode materials, enterprises have put forward higher requirements for the production of lithium batteries. [0003] At present, the reshaping and assembly of lithium battery negative e...

AI Technical Summary

Problems solved by technology

[0003] At present, the reshaping and assembly of lithium battery negative electrodes are done manually combined with semi-automatic equipment. The assembly efficiency is low, the quality of reshaping is difficult to guarantee, the output and quality cannot meet customer needs, and the market competitiveness of enterprises is reduced. Moreover, the assembly environment is harsh and harmful to human health. unfavorable
