Magnetic Holding Device for Cylindrical Workpieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pick-up devices for workpieces struggle to quickly and reliably hold workpieces of varying diameters without complex mechanical clamping mechanisms, requiring additional movements to actuate clamping units.
Innovation Solution
A magnetic force-generating unit integrated into the receptacle provides a non-contact holding force, allowing workpieces to be easily inserted and removed vertically, with a contact area design accommodating different diameters through angled surfaces, eliminating the need for mechanically movable fixing means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical clamping units with lever arms and compression springs are used, then workpieces can be held reliably, but the device complexity increases and additional movements are required to actuate the clamping units
Solution Approach 1:
The patent replaces the mechanical clamping system (lever arms, compression springs, stop units) with a magnetic field-based holding system. The magnetic force-generating unit creates a magnetic field that directly holds the workpiece on the contact area without mechanical contact, eliminating the need for complex mechanical actuation while maintaining reliable holding.
Solution Approach 2:
The invention extracts and removes the mechanical clamping components (lever arms, springs, stop units) from the system, retaining only the essential function of workpiece holding through magnetic force. This simplifies the device by taking out the disturbing mechanical elements that require actuation.
2Reliability
If mechanical clamping units are used, then workpieces can be held securely, but the picking up speed decreases due to additional actuation movements
Solution Approach 1:
By replacing the mechanical clamping system with a magnetic field-based system, the patent eliminates the need for actuation movements. The magnetic force-generating unit can be activated or deactivated electrically, allowing workpieces to be picked up and released quickly without manual or mechanical intervention, thus increasing productivity while maintaining secure holding.
3Ease of manufacture
If fixed contact areas are used, then workpieces of specific diameters can be held, but the adaptability to workpieces with varying diameters is limited
Solution Approach 1:
The magnetic force-generating unit provides a universal holding solution that can accommodate workpieces of various diameters. The magnetic field can be adjusted or redistributed to maintain effective holding force on different workpiece sizes, making the device versatile without requiring multiple fixed contact areas for different diameter specifications.
