Electrode Plate Centerline Correction for Battery Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deviation correction methods for electrode plates in battery cell winding rely on edge position corrections, which fail to account for the effective width of the electrode plate, leading to inefficient and inaccurate corrections, requiring manual adjustments to ensure quality.
Innovation Solution
A deviation correction apparatus that detects the width of the coating layer on the electrode plate to determine its centerline position, using this centerline as a reference for correction, allowing for automatic and precise alignment of anode and cathode plates without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If edge position deviation correction is performed using existing methods, then deviation correction is achieved, but manual adjustment is still required and correction accuracy is insufficient
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automatic control system that uses vision detection to identify electrode plate position and width, calculates deviation from standard centerline, and automatically adjusts the deviation correction mechanism to achieve precise alignment without manual intervention
Solution Approach 2:
The system enables self-correction by automatically detecting electrode plate parameters, calculating the required correction amount based on the difference between actual and standard centerlines, and autonomously adjusting the deviation correction mechanism to maintain accurate alignment
2Device complexity
If edge position correction is used as reference, then correction process is simple, but correction accuracy deteriorates when electrode plate width is abnormal
Solution Approach 1:
The patent changes the correction reference parameter from edge position to centerline position, which is dynamically calculated based on detected electrode plate width and position. This allows the system to adapt to varying plate widths while maintaining accurate centerline alignment for proper anode-cathode nesting
Solution Approach 2:
The system implements feedback control by continuously detecting electrode plate position and width, comparing actual centerline with standard centerline, and automatically adjusting the deviation correction mechanism based on the calculated deviation to maintain precise alignment
3Reliability
If manual adjustment is performed to ensure quality, then product quality is maintained, but production efficiency decreases
Solution Approach 1:
The patent replaces manual quality control operations with an automated vision-based detection and control system that continuously monitors electrode plate parameters and automatically adjusts deviation correction, maintaining high product quality while eliminating manual intervention and improving production efficiency
