Electrode Sheet Optical Detection to Prevent Conveyor Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stack manufacturing apparatuses for secondary batteries face issues where multiple electrode sheets overlap on the conveyor due to system errors, leading to potential damage to the sheets or adjacent devices.
Innovation Solution
An apparatus and method for detecting and transporting electrode sheets using a lighting member to emit light, a sensing member to detect reflected light, and a processor to analyze the image and determine the presence of the sheet, preventing overlapping by controlling the supply of sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a stack process is performed without detection, then productivity is improved, but electrode sheets may overlap and cause damage
Solution Approach 1:
The lighting member and sensing member are positioned to detect the presence of an electrode sheet in the supply region before the stack process begins. The processor analyzes the reflected light signal to determine whether the supply region is occupied, and only allows the stack process to proceed when the region is confirmed empty, preventing overlapping while maintaining productivity
2Reliability
If a detection system is added, then electrode sheet overlap is prevented, but device complexity increases
Solution Approach 1:
A lighting member is introduced as an intermediary to illuminate the supply region, enabling the sensing member to detect the presence of electrode sheets through reflected light analysis. This intermediary lighting system provides a simple and effective detection mechanism without requiring complex sensor arrays or processing systems
Solution Approach 2:
The mechanical or manual monitoring of the supply region is replaced with an optical detection system consisting of a lighting member and sensing member. The processor automatically analyzes the reflected light signals to determine sheet presence, eliminating the need for complex mechanical sensors or manual inspection mechanisms
