Electrode Plate Line Layout for Real-Time Meandering Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrode plate manufacturing facilities face issues with additional meandering of electrode sheets due to long traveling paths and delayed detection of meandering, leading to potential defects in the electrode plates.
Innovation Solution
An apparatus for manufacturing electrode plates is designed with an unwinder, a meandering corrector, a press puncher, a cutter, a detector, and a controller. The detector acquires images of the electrode sheet to determine if it meanders by measuring the height of the active material, and the controller adjusts the meandering corrector to correct any meandering, ensuring the active material protrudes correctly.

Engineering Contradiction Analysis
1Length of moving object
If a long traveling path is used from the LPC to the press blanking, then the electrode sheet can be processed, but additional meandering occurs
Solution Approach 1:
The traveling path is divided into multiple segments with intermediate support points (idling rolls) to reduce the effective length of each segment, thereby minimizing meandering while maintaining the overall processing capability
Solution Approach 2:
Idling rolls are introduced as intermediary elements between the LPC and press blanking to provide continuous support to the electrode sheet, preventing it from sagging or meandering during traversal
2Device complexity
If the inspector is placed too far from the LPC, then the facility layout is simplified, but meandering detection is delayed
Solution Approach 1:
The inspector is positioned upstream closer to the LPC to detect meandering earlier in the process, allowing corrective action to be taken before the electrode sheet travels further and meandering becomes more severe

AI summary
An apparatus for manufacturing an electrode plate, includes an unwinder on which an electrode reel is installed; a meandering corrector correcting meandering of an electrode sheet unwound from the electrode reel; a press puncher disposed at a rear end of the meandering corrector; a cutter disposed at a rear end of the press puncher; a detector disposed between the press puncher and the cutter to acquire an image of the electrode sheet; and a controller connected to the detector and the meandering corrector.
