Laser Marking Settings for Readable Heat-Shrink Battery Tubes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery cells require unnecessary labels that increase material costs, and existing methods do not efficiently write product information directly on heat shrinkable tubes without additional configurations.
Innovation Solution
A laser transmission characteristic value determination method is used to set and adjust frequency, marking speed, and focal distance to ensure that product information is written in a readable font size or line format directly on the heat shrinkable tube, eliminating the need for separate labels by applying heat and storing optimal laser settings for different battery cell sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a separate PET label is attached to the battery cell to display product information, then the product information can be delivered, but unnecessary material costs are added
Solution Approach 1:
The patent merges the label function with the heat shrinkable tube by directly marking information on the tube surface. The heat shrinkable tube serves dual purposes: providing insulation/protection and displaying product information through laser marking, thereby eliminating the need for separate PET labels and reducing material costs
Solution Approach 2:
The patent extracts the information display function from the separate PET label and transfers it to the heat shrinkable tube. By using laser marking technology, the information that was previously required on a separate label is now directly integrated into the existing heat shrinkable tube structure
2Device complexity
If laser marking is performed on the heat shrinkable tube, then the label configuration can be deleted, but the font size may be insufficient after heating
Solution Approach 1:
The patent applies preliminary action by performing laser marking on the heat shrinkable tube before the heating process. The marking is done on the unheated tube where the surface area is larger, ensuring that even after the tube shrinks during heating, the font size remains sufficient and readable
Solution Approach 2:
The patent applies parameter changes by adjusting laser marking parameters (frequency, marking speed, focal distance) based on the state of the heat shrinkable tube. The system determines optimal laser parameters for the unheated tube state to ensure that after heating and shrinkage, the marked information maintains adequate font size and readability
3Measurement precision
If laser parameters are optimized for each battery cell size and shape, then reading accuracy improves, but the process becomes more complex
Solution Approach 1:
The patent systematically changes laser parameters (frequency, marking speed, focal distance) based on different battery cell sizes and shapes. By establishing parameter determination methods that adapt to various cell configurations, the system achieves accurate marking across different product variants without requiring manual optimization for each case
Solution Approach 2:
The patent creates a universal laser parameter determination method that can handle multiple battery cell sizes and shapes. The system uses a standardized approach to determine appropriate laser parameters based on cell characteristics, making the process applicable across different product variants without requiring separate optimization procedures for each
