Transfer Tool Slider Mechanism for High-Speed Press Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transfer tools face limitations in achieving high-speed workpiece transfer and extended reach while minimizing interference with press devices and maintaining efficient operation, particularly in scenarios where the workpiece attitude needs to be adjusted.
Innovation Solution
A transfer tool with a strip-shaped frame, wrist-side and workpiece-side sliders, and a distal-end swing shaft attached to the workpiece-side slider, allowing for high-speed linear movement and attitude adjustment of the workpiece, coupled with an actuator for efficient power transmission and reduced friction, enabling precise and rapid workpiece transfer between press devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a long belt is used to couple the sliders for extended reach, then the reach is extended, but the friction increases and maintenance frequency increases
Solution Approach 1:
The transfer tool is divided into modular components: a frame, multiple sliders (wrist-side slider and workpiece-side slider), and a distal-end swing shaft. This segmentation allows the system to achieve extended reach through the coordinated movement of multiple shorter segments rather than relying on a single long belt, thereby reducing friction and maintenance requirements while maintaining the desired working range.
2Ease of operation
If the workpiece attitude is adjusted by moving the frame, then the attitude is changed, but the transfer speed and reach are reduced
Solution Approach 1:
The distal-end swing shaft is designed as a dynamic component that can rotate independently to adjust the workpiece attitude. This allows the workpiece orientation to be changed without moving the entire frame, enabling rapid attitude adjustment while maintaining the high transfer speed and extended reach capabilities of the slider mechanism.
3Speed
If high-speed transfer is achieved using a slide mechanism, then the transfer speed increases, but the device complexity increases
Solution Approach 1:
The slider mechanism serves multiple functions: it provides high-speed linear movement for transfer, enables extended reach through the frame structure, and allows attitude adjustment when combined with the distal-end swing shaft. This multi-functionality reduces the need for separate components, thereby managing device complexity while achieving high-speed transfer performance.
