Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrode rolling roll cleaning apparatuses have insufficient cleaning power, leading to residual contaminants on the rolling rolls, which can reduce the quality of electrodes and batteries during the manufacturing process.
Innovation Solution
A dual-stage cleaning apparatus with cleaning members having grain patterns oriented at specific angles (0-90 degrees, preferably 30-60 degrees) to enhance cleaning efficiency, using a combination of water and alcohol-based cleaning liquids, and incorporating scraping pads, air spray units, and heating units to remove contaminants effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single cleaning part with a cleaning member is used to clean the rolling roll, then the device complexity is low, but the cleaning power is insufficient and contaminants remain on the rolling roll
Solution Approach 1:
The cleaning apparatus is divided into multiple cleaning parts (first cleaning part, second cleaning part, third cleaning part) with cleaning members having different grain directions. Each cleaning part targets different types or orientations of contaminants, collectively providing comprehensive cleaning that a single cleaning part cannot achieve, thereby resolving the contradiction between cleaning power and device complexity.
Solution Approach 2:
Each cleaning member is designed with specific grain directions (first grain direction, second grain direction, third grain direction) tailored to address different contaminant orientations on the rolling roll surface. This localized optimization of cleaning characteristics in different areas/directions enhances overall cleaning effectiveness without requiring an overly complex system.
2Productivity
If cleaning members with different grain directions are used in multiple cleaning parts, then cleaning efficiency is improved and contaminants are effectively removed, but the device complexity increases
Solution Approach 1:
The cleaning members are segmented into multiple parts with distinct grain directions, allowing each segment to specialize in removing contaminants of specific orientations. This segmentation enables parallel cleaning actions on different portions of the rolling roll surface, improving overall cleaning efficiency while maintaining a manageable device structure through modular design.
Solution Approach 2:
The invention introduces the dimension of grain direction orientation as a new variable for cleaning effectiveness. By arranging cleaning members with grains in different directions (0-90 degrees, preferably 30-60 degrees) relative to the rolling roll rotation, the system addresses contaminants that a single-direction cleaning member cannot remove, thereby enhancing cleaning efficiency without proportionally increasing complexity.
3Reliability
If multiple cleaning parts with different grain directions are implemented, then cleaning power is improved and no residual cleaning liquid remains on the rolls, but the ease of operation decreases
Solution Approach 1:
The cleaning apparatus is segmented into multiple cleaning parts that operate simultaneously or sequentially on the rolling roll. Each cleaning part with its specific grain direction works independently but cooperatively, allowing the system to maintain high cleaning power while the integrated design ensures that operation remains straightforward through unified control of all cleaning parts.
Solution Approach 2:
The invention optimizes the grain direction parameters of cleaning members (specifically 0-90 degrees, preferably 30-60 degrees relative to rolling roll rotation) to achieve maximum cleaning effectiveness. This parameter optimization ensures thorough contaminant removal and complete drying of the rolling roll surface, while the standardized parameter ranges simplify operation and maintenance procedures.

AI summary
The present invention relates to an apparatus for cleaning press rolls for electrodes, comprising two or more cleaning units provided with cleaning members having grains. According to the present invention, the apparatus for cleaning press rolls for electrodes comprises a plurality of, i.e., two or more, cleaning units, wherein the cleaning units respectively comprise cleaning members having grains with different directions, thus allowing a residual cleaning solution and contaminants to be effectively removed. In addition, when press rolls are cleaned using the apparatus for cleaning press rolls according to the present invention, an aqueous cleaning solution and an alcoholic cleaning solution, which have different properties, can be used together, and after cleaning, the cleaning solutions do not remain on the press rolls, and thus subsequently, secondary contamination of electrodes is prevented, and accordingly, when electrodes are manufactured, the occurrence of defects in the electrodes can be reduced.
