Abstract

The invention discloses an automatic preparation process for a lithium iron phosphate power battery, which relates to the technical field of production of lithium iron phosphate power batteries. The process comprises the following processing sequence steps of: positive and negative electrode slice coating, diaphragm material winding and conveying, pole piece drying, pole lug welding, automatic winding, molding, cutting, sealing, core extracting, film loading, liquid injection, formation and encapsulating. According to the automatic process, the thickness is convenient to control, the internal structure of an electric core is consistent, and each position of the battery is of correspondingly consistent thickness; and a power battery produced by using the automatic process has high yield and a simple process.

Description

A kind of lithium iron phosphate dynamic battery automated preparation technology
Technical field
The present invention relates to the lithium iron phosphate dynamic battery production technical field.
Background technology
The preparation cost and the production cost of cells of current LiFePO 4 material are higher, and the battery rate of finished products is low.Through optimizing scale production process, improve production equipment and process control detection technique, realize automation, low cost, high efficiency production high-quality lithium iron phosphate dynamic battery, improved performance, qualification rate and the consistency of electrokinetic cell.
Summary of the invention
The object of the invention is to propose a kind of lithium iron phosphate dynamic battery automated preparation technology that can overcome the prior art defective.
Processing sequence step of the present invention is: the coating of positive and negative electrode sheet, diaphragm material are rolled up feeding, pole piece drying, lug welding, auto reeling, moulding, cut off, seal, move back core, go up film, fluid injection, are changed into and encapsulate.
Equipment such as the present invention can adopt full-automatic coating, coiling, fluid injection, changes into, encapsulation; Realize pole piece coiling, seal typing and move back core automatically; This technology integrates machinery, microelectronics, control, sensor technology automatically, realized automatic completion from the coating of positive and negative electrode sheet, diaphragm material volume feeding, pole piece drying, lug welding, auto reeling, moulding, cut off, seal, move back core, upward film, fluid injection, change into, the overall process of power lithium-ion battery core moulding such as encapsulation.This preparation technology can significantly improve production efficiency, improves the consistency and the rate of finished products of electrokinetic cell performance, reduces production costs.
Automation process thickness of the present invention is convenient to control, electric in-core bilge construction is consistent, and each position thickness of battery is also corresponding consistent; With the electrokinetic cell that this automation process is produced, qualification rate is high, and technology is simple.
Embodiment
The sequential steps of lithium iron phosphate dynamic battery automated preparation technology is: the coating of positive and negative electrode sheet, diaphragm material are rolled up feeding, pole piece drying, lug welding, auto reeling, moulding, cut off, seal, move back core, go up film, fluid injection, are changed into and encapsulate.
The present invention adopts High Precision Automatic coating machine, and automatic battery up-coiler, battery pole piece lug welding adhesive tape wrapping machine, auto reeling are with regard to machine, and liquid-filling machine for battery etc. have been realized serialization, automation and integrated that electrokinetic cell is produced.Semi-automatic or manual process tends to bring that thickness is difficult to control, electric in-core bilge construction heterogeneity, lug place, the easy mistake in barrier film ending place is thin or ultra problem such as thick, and production efficiency is lower, and brings problem for the consistency of battery.
