Mono-Cell Lamination Gloss Monitoring for Separator Defect Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mono-cell manufacturing processes face inefficiencies due to the difficulty in promptly identifying abnormal mono-cells, leading to increased defective product discard and reduced production efficiency, especially when separators are deformed by excessive pressure or lack of adhesion during the lamination process.
Innovation Solution
A mono-cell manufacturing apparatus equipped with a gloss meter that measures the glossiness of the separator to rapidly determine the adhesion and deformation status, allowing for immediate feedback and reducing defective product output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional defect determination methods are used after mono-cell manufacturing, then defect detection is performed, but it takes considerable time and many defective mono-cells are discarded
Solution Approach 1:
The patent replaces conventional mechanical/physical inspection methods with optical measurement using a gloss meter. The gloss meter measures the reflectivity of light from the separator surface to detect deformations, eliminating the need for time-consuming manual or mechanical defect determination processes while maintaining high detection accuracy
Solution Approach 2:
The patent changes the measurement parameter from physical inspection of separator adhesion and deformation to optical property measurement (glossiness/reflectivity). By measuring the glossiness of the separator surface, the system can rapidly detect deformations and adhesion issues without direct physical contact or complex testing procedures
2Strength
If conventional lamination pressure and heat are applied, then electrode and separator adhesion is achieved, but excessive pressure deforms separators and insufficient pressure reduces adhesion force
Solution Approach 1:
The patent implements a feedback mechanism where the gloss meter continuously monitors separator surface conditions during and after lamination. The measured glossiness values are fed back to the control system, which automatically adjusts the lamination pressure and temperature parameters in real-time to maintain optimal adhesion while preventing separator deformation
Solution Approach 2:
The patent dynamically changes lamination parameters (pressure, temperature, time) based on real-time glossiness measurements. By monitoring optical properties during the lamination process, the system can precisely control the degree of pressure and heat applied, ensuring adequate adhesion without exceeding the separator's deformation threshold
