Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workpiece holding devices using adhesive tapes face challenges in achieving sufficient holding force while minimizing the load required for peeling off the workpiece, leading to potential dropping or damage of the workpiece.
Innovation Solution
A workpiece holding device utilizing a flexible strip-like base material with a self-adhesive holding material, where the adhesive holding part is made flat for holding and curved for peeling, supported by a load receiving plate to prevent bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the adhesive holding surface is made large to increase holding force, then the holding force is improved, but the flexibility and ease of peeling deteriorate
Solution Approach 1:
The adhesive system is segmented into a flexible support layer and a thin self-adhesive layer. The support layer provides the necessary flexibility and mechanical strength, while the thin self-adhesive layer ensures easy peeling. This segmentation resolves the contradiction between large contact area for holding force and flexibility for ease of peeling.
Solution Approach 2:
The support layer is designed as a flexible film or sheet that can conform to the workpiece surface while maintaining ease of manipulation. The flexibility of this thin film structure allows the adhesive holding surface to be large for sufficient holding force while remaining easy to peel off without damaging the workpiece.
2Ease of operation
If a self-adhesive layer is used to reduce peeling force, then the ease of peeling is improved, but the holding force deteriorates
Solution Approach 1:
The invention merges the support function and adhesive function into a single integrated adhesive tape structure. The support layer and self-adhesive layer are combined in a specific configuration where the support layer provides mechanical strength and the self-adhesive layer provides holding force, achieving both adequate holding force and ease of peeling simultaneously.
Solution Approach 2:
The adhesive tape is constructed as a composite material system with a support layer and a self-adhesive layer. The support layer uses materials with high mechanical strength and appropriate flexibility, while the self-adhesive layer uses materials with specific surface energy properties. This composite structure resolves the contradiction between holding force and ease of peeling by distributing functions across different material layers.

AI summary
Provided is a workpiece holding device capable of holding a workpiece with a sufficient adhesive force and separating the held workpiece without applying a load to it. The workpiece holding device using an adhesive holding material that is self-adhesive includes: a flexible strip-like base material including an adhesive holding part to which the adhesive holding material is attached; a movement roller including a roll surface; and a load receiving plate that supports from below at least a portion of the strip-like base material that holds a workpiece on the adhesive holding part, in which the strip-like base material is wound around the roll surface of the movement roller with the adhesive holding part facing outward, (I) the adhesive holding part of the strip-like base material is made to be an adhesive holding surface that is flat so as to enable the workpiece to be held, (II) the adhesive holding part of the strip-like base material is curved along the roll surface of the movement roller so as to enable the workpiece to be peeled off, and when the workpiece is held on the adhesive holding surface, bending of the strip-like base material due to a weight of the workpiece can be prevented by means of the load receiving plate.
