Electrode Tape Calendering With Automatic Roller Opening for Defects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing calendering process for electrode tapes is inefficient due to manual interruptions caused by defects, leading to potential damage to rollers and reduced overall system effectiveness.
Innovation Solution
A method utilizing an open-loop and/or closed-loop control system for automatic defect detection and roller adjustment, allowing the calendering process to continue uninterrupted by adjusting the rollers to an open position before a defect reaches the roller gap, thereby preventing damage and optimizing system effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual monitoring is used to detect defects, then roller damage can be prevented, but overall system effectiveness decreases due to frequent manual interruptions
Solution Approach 1:
The patent replaces the manual mechanical monitoring system with an automated optical sensor system. Sensors detect defects on the electrode tape surface, and an automated control system triggers roller opening/closing actions, eliminating the need for manual intervention while maintaining roller protection and improving productivity.
Solution Approach 2:
The system enables self-service operation where the calendering device automatically detects defects, decides when to open/close rollers, and executes the protective actions without human intervention. This autonomous operation prevents roller damage while maintaining continuous production flow.
2Reliability
If the calendering process is interrupted manually for each defect, then roller damage is avoided, but production time is lost
Solution Approach 1:
The automated sensor system detects defects before they reach the roller gap and pre-triggers the roller opening action. This preliminary detection and response mechanism ensures rollers are protected in advance, eliminating the need for reactive interruptions and maintaining continuous production timing.
Solution Approach 2:
The system implements a feedback loop where sensors continuously monitor the electrode tape, automatically signal defect detection, trigger roller position changes, and return to normal calendering operation. This closed-loop control minimizes production time loss by rapidly responding to defects without manual intervention delays.
3Productivity
If automatic control system is implemented for defect detection and roller adjustment, then productivity increases, but device complexity increases
Solution Approach 1:
The patent introduces an automated control system as an intermediary between defect detection and roller actuation. This intermediary processes sensor signals and automatically triggers roller position changes, bridging the gap between detection and protection actions while maintaining system productivity and managing complexity through modular design.

AI summary
A method for calendering an electrode tape via a calendering process, in which an electrode tape is passed through a roller gap of a pair of rollers of a calendering device, namely by compressing the electrode tape. During the calendering process a defect detection step is carried out, in which at least one defect of the electrode tape is directly or indirectly detected. If a defect is detected during the defect detection step, the pair of rollers is adjusted from a calendering position of the pair of rollers to an open position of the pair of rollers in an opening step, and this is before the defect reaches the roller gap. The defect detection step and/or the opening step is carried out, preferably automatically or fully automatically, via an open-loop and/or closed-loop control system of the calendering device.
