Support Rail Actuation for Rocking-Free Workpiece Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cutting and laser processing apparatuses face challenges in smoothly moving a workpiece along support rails without causing rocking movements, which hinders accurate image acquisition of processed states, due to gaps between the annular frame and supporting rails.
Innovation Solution
A processing apparatus with a controller-actuated support rail system that sandwiches the workpiece between opposing rails, using load detection to adjust the rail positions, ensuring a stable and gap-free movement to prevent rocking and allow for precise image pickup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the annular frame is moved toward the cassette using the existing support rail system, then the workpiece can be transported, but the gap between the frame and rails causes rocking movement that prevents accurate image acquisition
Solution Approach 1:
A cushioning member (elastic element) is introduced as an intermediary between the annular frame and the support rails. This mediator absorbs the gap and prevents direct contact that would cause rocking, enabling smooth transport while maintaining stability for accurate image acquisition.
Solution Approach 2:
The elastic cushioning member is pre-installed between the frame and rails to anticipate and prevent rocking movement before it occurs. This prior cushioning ensures that when the frame moves along the rails, any gaps are already compensated for, preventing instability during transport and image acquisition.
2Adaptability or versatility
If the support rails are positioned to accommodate the annular frame, then the frame can be moved, but gaps remain that cause instability and rocking
Solution Approach 1:
The cushioning member serves as a mediator that bridges the gap between the support rails and annular frame. It provides continuous contact and support, eliminating instability caused by gaps while maintaining compatibility with the existing frame structure and enabling stable workpiece transport.
3Stability of the object's composition
If the gap between the annular frame and support rails is reduced, then stability improves, but the structural design becomes more complex
Solution Approach 1:
Rather than redesigning the entire support rail system to eliminate gaps, a simple cushioning member is introduced as an intermediary. This approach improves stability by compensating for gaps without requiring complex structural modifications to the rails or frame, maintaining system simplicity.
Solution Approach 2:
The cushioning member's elasticity parameter is utilized to dynamically compensate for gaps. By changing from a rigid support system to one with elastic compliance, the system adapts to gap variations and maintains stability without increasing structural complexity.
