Magnetic Tip Holder With QR Offset Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional scribe device's tip replacement process is cumbersome and prone to misalignment errors, leading to inefficient and unstable scribe line formation due to the need for manual correction and potential installation of incorrect tips, especially when dealing with small tips and varied substrate sizes.
Innovation Solution
A tip holder installation structure that includes a nearly cylindrical member with flat parts and a notch, featuring a pin groove for retaining the tip and a 2-dimensional code for storing offset data, allowing for easy correction and alignment using a magnet and parallel pin mechanism, reducing the need for manual test scribe corrections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual tip installation and alignment correction is used, then flexibility in tip replacement is achieved, but time consumption and alignment accuracy deteriorate
Solution Approach 1:
Offset data for each tip holder is pre-measured and stored in a database before actual use. When a tip holder is installed, the system automatically retrieves and applies the corresponding offset data, eliminating the need for real-time manual measurement and correction during tip replacement operations.
Solution Approach 2:
The manual mechanical alignment correction process is replaced by an automated information processing system. The system uses stored offset data to automatically calculate and apply position corrections through the control unit, substituting manual measurement and adjustment operations with automated digital processing.
2Manufacturing precision
If manual alignment correction is performed after tip installation, then positioning accuracy can be adjusted, but operational efficiency and productivity deteriorate
Solution Approach 1:
All alignment correction data is pre-calculated and stored in the database during tip holder manufacturing or initial setup. This preliminary preparation eliminates the need for time-consuming manual alignment corrections during actual scribe operations, thereby maintaining high positioning accuracy while improving operational efficiency.
Solution Approach 2:
The system implements an automated feedback mechanism where the control unit retrieves stored offset data and automatically applies position corrections during scribe operations. This closed-loop approach ensures consistent positioning accuracy without requiring manual intervention, thereby maintaining precision while enhancing productivity.
3Manufacturing precision
If frequent manual offset corrections are performed, then scribe line accuracy is maintained, but device complexity and operational complexity increase
Solution Approach 1:
The complex alignment correction calculations are extracted from the operational system and pre-computed during tip holder manufacturing or initial setup. The offset data is stored in the database and automatically retrieved during operations, separating the complex computational task from the operational workflow and simplifying the device's operational complexity.
Solution Approach 2:
The system performs automatic self-correction by retrieving and applying stored offset data through the control unit without requiring manual intervention. This self-service mechanism maintains scribe line accuracy automatically, eliminating the need for operators to perform complex manual alignment corrections.
4Adaptability or versatility
If manual tip holder installation is used, then adaptability to different tip types is achieved, but installation precision and consistency deteriorate
Solution Approach 1:
The system uses a universal database structure and control mechanism that can store and retrieve offset data for different types of tip holders. The standardized interface and automated correction system accommodate various tip holder designs while maintaining consistent installation precision through automatic position compensation.

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.
