Peeling Apparatus Obtuse Angle Support Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The peeling process in manufacturing flexible devices such as semiconductor, display, and light-emitting devices often results in low yield due to complications in separating functional elements from substrates, with existing methods like laser ablation and manual peeling facing issues of crack formation and adhesion failures.
Innovation Solution
A peeling apparatus with a support body supply unit, tension applying mechanisms, and a structure body that bends the support body at an obtuse angle to divide the process member into two parts, utilizing a convex surface for peeling and a fixing mechanism to secure the separated members, while also applying tension and controlling the peeling angle to prevent slack and crack formation.

Engineering Contradiction Analysis
1Reliability
If laser ablation is used to separate the peeled layer from the formation substrate, then peeling can be achieved, but cracks may form and adhesion failures occur reducing yield
Solution Approach 1:
The patent replaces laser ablation (thermal/optical method) with a mechanical peeling system consisting of a peeling roller and support body. The peeling roller applies controlled mechanical force to separate the peeled layer from the formation substrate, eliminating the harmful thermal effects and crack formation associated with laser ablation while achieving reliable peeling.
Solution Approach 2:
The patent introduces a support body as an intermediary element between the peeling roller and the peeled layer. The support body provides stable support during the peeling process, distributes the applied force uniformly, and prevents direct contact that could cause cracks or adhesion failures, thereby improving peeling yield.
2Reliability
If manual peeling is used to separate layers, then adhesion can be controlled, but productivity is reduced and yield remains low
Solution Approach 1:
The patent creates a self-contained automated peeling system where the peeling roller and support body work together to automatically separate the peeled layer from the formation substrate. The system applies controlled tension through the support body and uses the peeling roller to initiate and maintain the peeling process, eliminating the need for manual intervention while maintaining high yield through controlled force application.
Solution Approach 2:
The patent extracts the peeling function from manual operations and implements it as a dedicated automated apparatus. The peeling roller and support body constitute a specialized subsystem that performs peeling automatically, separating this function from general manufacturing operations and enabling both high productivity and high yield through dedicated design.
3Object-affected harmful factors
If tension is applied to the support body during peeling, then crack formation is reduced, but device complexity increases
Solution Approach 1:
The patent segments the peeling system into distinct functional components: the peeling roller for initiating peeling, the support body for applying distributed tension, and the peeling apparatus for coordination. This segmentation allows each component to perform its specific function efficiently, applying tension uniformly through the support body to prevent cracks while keeping the overall device relatively simple through modular design.
