Separator Hot-Press Fixation for Jellyroll Unit Plate Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the lamination process of jellyrolls, unit plates tend to shift relative to separators due to poor thermal compounding, making it difficult to detect and adjust, which affects lamination precision and yields unqualified jellyrolls.
Innovation Solution
A method and device that obtain peripheral position information of unit plates between separators using a CCD camera and control a hot-pressing device to adhere the separators at specific positions, preventing plate shifting by forming a closed space around the plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional lamination process is used without position detection, then the production speed is maintained, but the unit plates shift relative to separators resulting in poor lamination precision
Solution Approach 1:
The system performs preliminary detection of unit plate positions using a CCD camera before the hot-pressing operation. The controller receives position information and calculates peripheral positions in advance, then guides the hot-pressing device to apply pressure only at the required peripheral locations. This preliminary detection and calculation enable precise lamination without requiring complex real-time monitoring systems throughout the entire process.
Solution Approach 2:
Instead of applying uniform hot-pressing across the entire lamination area, the system identifies and applies pressure only at the peripheral positions of unit plates where separators need to be adhered. The controller calculates specific peripheral coordinates based on detected plate positions and directs the hot-pressing device to these localized areas, optimizing both precision and efficiency.
2Productivity
If hot-pressing is applied uniformly across the entire lamination area, then thermal compounding is ensured, but unit plates may still shift and production time increases
Solution Approach 1:
The system applies hot-pressing locally only at the peripheral positions of unit plates rather than uniformly across the entire lamination area. The controller receives position information from the CCD camera, calculates the peripheral coordinates of each unit plate, and directs the hot-pressing device to apply pressure only at these specific locations where separator adhesion is needed, thereby maintaining position stability while reducing production time.
Solution Approach 2:
The system performs preliminary detection of unit plate positions using a CCD camera before the hot-pressing operation. The controller receives position information and calculates peripheral positions in advance, then guides the hot-pressing device to apply pressure only at the required peripheral locations. This preliminary detection and calculation enable precise lamination without requiring complex real-time monitoring systems throughout the entire process.
3Manufacturing precision
If detection device is added to monitor unit plate positions, then lamination precision can be improved, but the device complexity and cost increase
Solution Approach 1:
The system performs preliminary detection of unit plate positions using a CCD camera before the hot-pressing operation. The controller receives position information and calculates peripheral positions in advance, then guides the hot-pressing device to apply pressure only at the required peripheral locations. This preliminary detection and calculation enable precise lamination without requiring complex real-time monitoring systems throughout the entire process.
Solution Approach 2:
The system uses a CCD camera to create an optical copy or image of the unit plate positions, converting physical position information into detectable signal data. The controller processes these image signals to determine plate positions and calculate peripheral coordinates, enabling precise control without direct physical contact or complex sensing mechanisms at the pressing points.
