Resin Sheet Peeling Method Using Local Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for peeling resin sheets from plate-shaped objects require additional consumable components, such as thermocompression sheets, which increase costs, and struggle to form a peeling origin point when the resin sheet is strongly adhered to the object.
Innovation Solution
A peeling method involving heating an end part of the resin sheet to form a peeling origin point, allowing for easy removal of the resin sheet from the plate-shaped object without the need for additional consumable components, using a thermoplastic resin sheet without an adhesive layer that is stuck to the object by mechanical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a thermocompression sheet is used to peel the resin sheet, then the peeling process can be completed, but additional consumable components are required which increases cost
Solution Approach 1:
The invention extracts and removes the adhesive layer from the resin sheet, transforming it into a non-adhesive resin sheet. This eliminates the need for thermocompression sheets or other additional consumable components during peeling, as the resin sheet can be peeled directly from the workpiece without requiring extra materials to facilitate the peeling process.
Solution Approach 2:
The resin sheet is designed to be self-peelable by utilizing its own thermal properties. When heated, the resin sheet undergoes thermal expansion and softening, allowing it to be peeled from the workpiece using only itself as the peeling medium, without requiring external consumable components like thermocompression sheets.
2Quantity of substance
If a claw part is inserted to peel the resin sheet, then no thermocompression sheet is needed, but it is difficult to allow entry of the claw and form a peeling origin point if the resin sheet is strongly in tight contact with the workpiece
Solution Approach 1:
The invention changes the physical parameters of the resin sheet by heating it. The heat causes the resin sheet to soften and expand thermally, creating a gap between the resin sheet and the workpiece surface. This parameter change enables easy formation of a peeling origin point without requiring claw insertion, as the heated resin sheet naturally separates from the workpiece.
Solution Approach 2:
The invention performs preliminary heating of the resin sheet before peeling. This preliminary thermal action causes the resin sheet to expand and soften in advance, creating natural separation points that facilitate subsequent peeling without requiring mechanical claw insertion or other complex preliminary actions.
3Ease of operation
If the resin sheet is heated through the plate-shaped object, then the peeling origin point can be formed easily, but energy is consumed for heating
Solution Approach 1:
The invention applies heating locally only to the resin sheet rather than the entire workpiece assembly. By targeting only the resin sheet for heating, the energy consumption is minimized while still achieving the necessary thermal expansion and softening to facilitate peeling origin point formation. The heating is applied in a controlled manner to the specific region where peeling is needed.
Applied Scientific Principles

AI summary
There is provided a peeling method of a resin sheet for peeling off the resin sheet from a plate-shaped object to which the resin sheet is stuck. The peeling method includes a resin sheet heating step of heating an end part of the resin sheet of the plate-shaped object to which the resin sheet is stuck to turn up the resin sheet from the end part and form a peeling origin point and a resin sheet removal step of removing the resin sheet from the plate-shaped object through peeling off the resin sheet from the peeling origin point.
