Conveyor Plate Stop Mechanism for Battery Electrode Foil Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In battery module manufacturing, components like positive electrodes, negative electrodes, and electrolytes are not inspected for abnormalities before laminate battery production, leading to wastage of battery modules if issues are detected after completion.
Innovation Solution
An apparatus with a sheet-shaped electrode conveyance device and metal foil bonding device that temporarily stops conveyor plates with abnormal metal foil before bonding, preventing defective electrodes from being processed and reducing wastage by ensuring only normal components are used for stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If components are not inspected for abnormalities before laminate battery production, then production efficiency is maintained, but battery modules are wasted when abnormalities are detected after completion
Solution Approach 1:
The patent implements preliminary inspection of components (positive electrodes, negative electrodes, electrolytes) for abnormalities before they are assembled into laminate batteries. The inspection device detects defects in advance, and the control device prevents abnormal components from being processed further, thereby ensuring component quality without causing wastage of finished battery modules.
Solution Approach 2:
The patent employs a feedback mechanism where the inspection device continuously monitors component quality, and the control device receives this information to make real-time decisions about whether to proceed with processing. This closed-loop feedback system allows the production line to maintain high reliability by preventing abnormal components from advancing while keeping the overall production efficient.
2Productivity
If abnormal components are processed without detection, then production flow is maintained, but defective products are created causing material wastage
Solution Approach 1:
The inspection device performs preliminary detection of abnormal components before they enter the assembly process. By identifying defects in advance, the system prevents abnormal components from being processed into defective laminate batteries, thereby eliminating material wastage while maintaining smooth production flow through targeted intervention rather than complete line stoppage.
Solution Approach 2:
The control device extracts or removes abnormal components from the production flow by preventing their further processing. When an abnormal component is detected, the control device stops the conveyance of that specific component to the assembly station, effectively taking it out of the production stream before it can become a defective finished product, thus preventing material wastage.

AI summary
A metal foil bonding device (50) for bonding pieces of metal foil (2) on the successively conveyed sheet-shaped electrodes (1) on the conveyor plates (20) is provided. When it is detected that there is an abnormality in a piece of metal foil (2) to be bonded to the sheet-shaped electrode (1) on the conveyor plate (20) next conveyed to the metal foil bonding device (50), the conveyor plate (20) next conveyed to the metal foil bonding device (50) is temporarily stopped right before the metal foil bonding device (50).
