Adhesive Cleaning Roller for Battery Cell Surface Foulant Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the manufacturing process of battery cells, foulants can adhere to the surface and cause damage when roller-pressed, leading to potential peeling of the laminate film and performance issues.
Innovation Solution
A battery cleaning device with adhesive cleaning rollers that clean the flat surfaces of battery cells prior to roller-pressing, using static electricity elimination and transfer rollers to remove foulants effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If roller-pressing is performed to press out gas from the battery element, then electrolyte impregnation is improved, but the battery cell surface may be scratched by foulants adhering to the surface
Solution Approach 1:
The cleaning roller removes foulants from the battery cell surface before the roller-pressing operation. This preliminary cleaning action prevents the foulants from causing surface scratches during subsequent pressing, while still allowing the pressing operation to achieve proper electrolyte impregnation by pressing out gas from the battery element.
2Object-affected harmful factors
If the battery cell surface is cleaned before roller-pressing, then surface damage is prevented, but the manufacturing process complexity increases
Solution Approach 1:
The cleaning roller is integrated into the existing roller-pressing apparatus, combining the cleaning function with the pressing operation. The cleaning roller and pressing roller are arranged to work in sequence within the same device, eliminating the need for a completely separate cleaning station and reducing overall process complexity.
Solution Approach 2:
The cleaning roller acts as an intermediary element between the battery cell and the pressing roller. It removes foulants that would otherwise be transferred to the battery cell surface during pressing, thereby preventing surface damage without requiring complex protective measures on the battery cell itself.
