AI Technical Summary

Technical Problem

In the existing lithium battery stacking machine, the pole-piece cache mainly relies on belt cache, resulting in limited number of pole-piece caches. Failure of die-cutter or lamination machine is prone to material breakage, affecting production efficiency and equipment productivity.

Method used

The material box is used to buffer the pole sheet, and the pole sheet is transferred from the conveyor belt to the material box through a mechanical suction cup to serve as a temporary buffer position. When the die-cutter or lamination machine is shut down, the pole sheet in the material box is transferred back to the conveyor line to ensure the continuity of the pole sheet supply.

Benefits of technology

It has achieved continuous and uninterrupted supply of pole pieces, improved production efficiency, greatly improved equipment productivity, reduced production time, and solved the problem of tight layout of the cutter and large space.

Abstract

The invention belongs to the technical field of lithium batteries, and mainly relates to a lithium battery cutting and stacking all-in-one machine storage device and method, and the device comprises a die cutting machine, a stacking machine, a conveying belt, a material box and a mechanical suction cup. The die-cutting machine is used for cutting a positive / negative electrode roll material into single positive and negative electrode plates with better consistency, the lamination machine is used for assembling the positive and negative electrode plates into qualified laminated cores in a manner of stacking the positive and negative electrode plates or a diaphragm Z-shaped belt conveying manner, the conveying belt is a belt which is not easy to slip and is provided with vacuum holes, the positive and negative electrode plates are adsorbed on the belt through a vacuum adsorption effect, and the positive and negative electrode plates are conveyed to the die-cutting machine. The conveying device is driven by a motor or a servo motor to convey positive / negative pole pieces to a designated position, the material box is a temporary buffering device of the pole pieces, and the mechanical arm is used for taking the pole pieces and placing the pole pieces to the designated position through movement. The efficiency of the die-cutting machine is generally higher than that of a lamination machine, a material box caching mode is adopted, continuous and uninterrupted pole piece conveying is achieved, the production efficiency is improved, the equipment utilization rate is greatly improved, and the production time is shortened.
