Tip Holder Offset Data Encoding for Scribe Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scribe devices face challenges in efficiently replacing tips, leading to prolonged replacement times and potential misalignment issues, which can result in unstable or abnormal scribe lines due to the need for manual offset measurement and correction, especially when dealing with small tips and varied scribe conditions.
Innovation Solution
A tip holder integrated with a wheel tip that retains offset data in a code format, allowing for easy correction and alignment by reading the code and adjusting the scribe head and substrate movement based on pre-recorded offset data, eliminating the need for manual measurement and reducing installation errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual offset measurement and correction is performed during tip replacement, then alignment accuracy can be adjusted, but replacement time is prolonged and operation complexity increases
Solution Approach 1:
Offset data is pre-measured and recorded on the tip holder itself during tip manufacturing or previous installation. This eliminates the need for manual offset measurement and correction during tip replacement, as the data is already available on the holder for direct input into the control unit, significantly reducing replacement time while maintaining alignment accuracy
Solution Approach 2:
The offset data is copied from the previous tip holder configuration and stored directly on the new tip holder. This allows the system to reuse proven alignment data without requiring重新 measurement, reducing both time and operational complexity while preserving manufacturing precision
2Manufacturing precision
If manual offset measurement and correction is performed during tip replacement, then alignment can be adjusted, but operation complexity and potential for error increase
Solution Approach 1:
The tip holder is equipped with a recorded data storage unit that automatically stores and provides offset data. During replacement, the system automatically reads this data from the new tip holder and inputs it to the control unit without requiring manual measurement or complex adjustment procedures, simplifying operation while maintaining precision
Solution Approach 2:
The manual mechanical process of measuring and adjusting offset is replaced by an automated electronic system that reads pre-recorded data from the tip holder's storage unit and automatically inputs it to the control unit, reducing operational complexity and minimizing human error
3Reliability
If tip replacement is performed frequently to maintain scribe quality, then scribe line stability is improved, but productivity decreases due to repeated replacement operations
Solution Approach 1:
Offset data is pre-recorded on the tip holder during manufacturing or previous installation, enabling rapid tip replacement without manual measurement. This reduces the time penalty associated with frequent tip changes, allowing more frequent replacements to maintain scribe quality while minimizing productivity loss
Solution Approach 2:
The automated data retrieval system allows operators to quickly replace tips by simply loading new holders with pre-recorded data, without requiring complex adjustment procedures. This streamlines the replacement process, making frequent tip changes less disruptive to overall productivity while maintaining scribe line stability

AI summary
A tip 14 is rotatably attached to a tip holder 10. The tip holder 10 is made into a cylindrical shape and its end has an installation part 16. An opening is arranged at a holder joint. The tip holder 10 is attracted by a magnet for attachment so that detaching and attaching can be performed easily. Tip offset data is recorded as a 2-dimensional code 17 on the surface of the tip holder 10. When replacing the tip holder, the offset data is read out and inputted to a scribe device, thereby canceling the offset. This eliminates the operation required for correction when attaching/detaching the tip holder and enables easy tip replacement during a short time of device stop.
