Dual-Pad Roller Cleaning Assembly for Slurry and Dust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rollers used in the manufacturing process of battery electrodes can become contaminated by foreign substances such as undried slurry or dust, leading to transfer of contaminants to the current collector or damage to the collector.
Innovation Solution
A roller cleaning apparatus with a first pad and a second pad, fixed at a predetermined distance by a head, and driven by an assembly to remove foreign substances, optionally using a cleaning solution and supported by jigs to maintain contact and adjust angles and distances for effective cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single pad is used to clean the roller, then the structure is simple, but the cleaning effectiveness is insufficient for recurring contamination
Solution Approach 1:
The cleaning apparatus is divided into multiple functional pads: a first pad for initial foreign substance removal and a second pad for cleaning recurring contamination. This segmentation allows each pad to specialize in specific cleaning tasks, improving overall cleaning effectiveness while maintaining manageable structural complexity
Solution Approach 2:
A head component serves as an intermediary structure that fixes and positions both pads at predetermined distances from each other. This intermediary element coordinates the action of multiple pads, enabling effective cleaning of recurring contamination without requiring a overly complex integrated system
2Reliability
If multiple pads are used to clean different areas, then cleaning coverage is improved, but the device complexity increases
Solution Approach 1:
Multiple pads are merged into a single integrated cleaning apparatus with a common head structure. The first and second pads are fixed to the same head at predetermined distances, allowing coordinated cleaning action while sharing structural support, thereby reducing overall device complexity despite increased cleaning coverage
Solution Approach 2:
The head structure serves multiple functions: it fixes both pads, maintains predetermined distances between them, and enables coordinated movement across the roller surface. This multi-functionality reduces the need for separate structural elements for each pad, simplifying the overall device design
3Manufacturing precision
If the roller is cleaned frequently to prevent contamination transfer, then product quality is maintained, but production time is lost
Solution Approach 1:
The cleaning apparatus performs preliminary cleaning actions by positioning pads at predetermined distances to address contamination before it spreads or causes damage. The first pad removes foreign substances proactively, and the second pad prevents recurring contamination, reducing the need for frequent production interruptions
Solution Approach 2:
The cleaning operation is designed to be continuous and efficient, with the first and second pads working in sequence without requiring separate cleaning cycles. The apparatus maintains continuous contact with the roller surface at optimized distances, enabling sustained cleaning action that prevents contamination buildup during production

AI summary
Proposed is a technology of a roller cleaning apparatus. The roller cleaning apparatus includes a first pad configured to remove foreign substances by being in contact with a surface of a roller, a second pad configured to be in contact with the surface of the roller while passing through an area through which the first pad has passed from the surface of the roller, a head configured to fix the first pad and the second pad such that the first pad and the second pad are spaced apart from each other by a predetermined distance, and a driving assembly configured to move the head to a portion of the roller to which foreign substances are attached.
