Scribing Tool Change Mechanism Using Suction Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing scribe apparatuses face challenges in improving productivity, tool compatibility, and fool-proof functionality, particularly in reducing automatic tool replacement time, enhancing compatibility with various scribing tools, and ensuring safe and correct operation during tool changes.
Innovation Solution
A tool change mechanism is introduced that includes a remover for extracting used scribing tools, a cartridge for accommodating multiple tools, and a transfer nozzle that moves tools using air suction, allowing for quick and safe replacement of scribing tools between the holder joint and the cartridge, with features like a tool absorbing part, suction tube, and lifting mechanism for vertical movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual tool replacement is used, then operation flexibility is maintained, but productivity decreases due to longer replacement time
Solution Approach 1:
The system performs automatic tool replacement without operator intervention. The remover automatically detaches used tools from the holder joint, and the transfer nozzle automatically transfers new tools from the cartridge to the holder joint, enabling the system to service itself during operation.
Solution Approach 2:
The transfer nozzle acts as an intermediary component that bridges the cartridge and holder joint. It receives tools from the cartridge, holds them temporarily, and transfers them to the holder joint, enabling automated tool replacement while the apparatus operates.
2Adaptability or versatility
If multiple scribing tools are supported, then tool compatibility improves, but device complexity increases
Solution Approach 1:
The cartridge is designed as a universal container that can accommodate multiple different types of scribing tools. The holder joint and transfer nozzle are designed with universal interfaces that can handle various tool configurations, enabling one system to perform multiple tooling functions.
Solution Approach 2:
The tool replacement system is segmented into independent functional modules: the cartridge storing multiple tools, the remover detaching tools from the holder joint, and the transfer nozzle transferring tools. This segmentation allows each component to be optimized for its specific function while maintaining overall system versatility.
3Productivity
If automatic tool replacement is implemented, then productivity increases, but fool-proof functionality decreases due to potential erroneous operations
Solution Approach 1:
The system incorporates recognition functionality that detects whether a scribing tool is properly attached to the holder joint before resuming operation. This feedback mechanism ensures that only correctly installed tools are used, preventing erroneous operations while maintaining automated replacement benefits.
Solution Approach 2:
The system performs verification checks before resuming scribing operations after tool replacement. The recognition function confirms proper tool attachment in advance, cushioning against potential errors by preventing operation with incorrectly installed tools.
