Electrode Rolling Gap Compensation for Uniform Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for rolling electrodes struggle to maintain uniform thickness during changes in rolling speed, leading to inconsistencies in electrode quality.
Innovation Solution
A method involving a rolling speed-rolling space compensation value table is used to automatically adjust the space between rolling rolls, ensuring constant space and thus maintaining uniform electrode thickness even during speed changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rolling speed is changed during electrode rolling, then productivity is improved, but the thickness uniformity deteriorates because the space between rolling rolls cannot be maintained constant
Solution Approach 1:
The patent pre-calculates and stores compensation values for different rolling speeds in a table before the actual rolling process. When rolling speed changes, the corresponding compensation value is retrieved and applied to adjust the rolling roll space, eliminating the need for real-time complex calculations and enabling quick adaptation to speed changes while maintaining thickness uniformity.
Solution Approach 2:
The patent changes the rolling roll space parameter based on rolling speed parameter changes by applying compensation values. As rolling speed increases or decreases, the rolling roll space is adjusted according to pre-determined compensation values, ensuring that the electrode thickness remains constant despite speed variations.
2Manufacturing precision
If multiple corrections of the rolling roll space are performed to reach targeted thickness after speed change, then manufacturing precision is improved, but the time consumption and process complexity increase
Solution Approach 1:
The compensation values are pre-calculated and stored in a table before the rolling process. This allows the system to immediately apply the correct compensation when rolling speed changes, eliminating the need for multiple iterative corrections and significantly reducing the time required to achieve targeted thickness accuracy.
Solution Approach 2:
The patent implements a feedback mechanism where the actual rolling speed is monitored and used to select the appropriate compensation value from the pre-established table. This closed-loop control ensures that the rolling roll space is automatically adjusted to the correct value based on the actual operating conditions, achieving high precision with minimal corrections.
