Feeding Device Guiding Assembly for Scratch-Free Workpiece Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In surface treating processes like anodizing, workpieces are easily scratched by elastic clips used in fixtures during the hanging process, which is a common issue in existing technologies.
Innovation Solution
The feeding device employs guiding assemblies with first and second guiding members that deform to securely hold workpieces, using guiding grooves and elastic portions to resist against inner walls without direct contact, preventing scratches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic clips are used to securely hang workpieces on fixtures, then the workpieces are firmly held in place, but the workpieces are easily scratched by the elastic clips during the hanging process
Solution Approach 1:
The patent introduces guiding assemblies as intermediary components between the elastic clips and the workpieces. These guiding assemblies include guiding members with guiding grooves that guide the elastic portions of the clips, ensuring they contact only specific non-critical areas of the workpiece (such as corners or edges) rather than the main surface, thus preventing scratches while maintaining secure holding
Solution Approach 2:
The guiding assemblies create localized contact points where the elastic clips interact with the workpiece. By designing the guiding grooves to direct contact to specific locations (corners, edges, or designated areas), the patent ensures that only local areas of the workpiece are contacted, protecting the overall surface quality while maintaining the gripping function
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively secures workpieces without scratching them, ensuring reliable handling and processing in surface treating processes like anodizing by using guiding assemblies that manage the elastic portions to resist against inner walls of the workpieces.
Implementation Method 1
The fixture includes two elastic clips bent toward each other. In use, the two elastic clips are deformed toward each other by a deforming mechanism, and then are received in the workpiece. After releasing the two elastic clips, the free ends of the two elastic clips resist against opposite inner walls of the workpiece

AI summary
A feeding device is used for hanging a workpiece on a fixture. The fixture includes two elastic portions. The feeding device includes a base for carrying the workpiece, a mounting seat, a driving member for driving the mounting seat, a guiding assembly, and a driving mechanism mounted on the mounting seat and connected to the guiding assembly for driving the guiding assembly. The guiding assembly passes through the base, and includes first and second guiding members. The driving member is capable of driving the first and second guiding members in the workpiece. The driving mechanism is capable of driving the first and second guiding members move away from each other to a position adjacent the inner walls of the workpiece, and the elastic portions resist against the inner walls of the workpiece, such that the workpiece is hung on the fixture.
