Flexible Display Panel Removal Roller Transfer Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing flexible display panels are inefficient as they require a larger roller to accommodate larger panels, increasing costs and complexity due to the need for a clamp that rolls along with the roller.
Innovation Solution
An apparatus comprising a roller, a linear motion member, and a fastening apparatus that allows the flexible display panel to be wound onto the roller without changing its size, using a linear motion to transfer the panel from the roller to the linear motion member, eliminating the need for a clamp and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a larger roller is used to accommodate larger flexible display panels, then the panel size capability is improved, but the device cost and space occupation increase
Solution Approach 1:
The flexible display panel is divided into two portions: a first portion wound on the roller and a second portion on the carrier board. This segmentation allows a fixed-size roller to handle panels of various sizes by adjusting the distribution of panel portions between the roller and carrier board, resolving the contradiction between panel size capability and roller size.
Solution Approach 2:
A transfer apparatus acts as an intermediary between the roller and carrier board, enabling the flexible display panel to be transferred from the carrier board to the roller. This intermediary mechanism allows the fixed-size roller to accommodate larger panels indirectly through the transfer process, without requiring the roller itself to be larger.
2Ease of operation
If a clamp that rolls along with the roller is used to take the flexible display panel off, then the panel removal function is improved, but the mechanism complexity and cost increase
Solution Approach 1:
The clamp mechanism is extracted from the roller system and integrated into the transfer apparatus instead. The transfer apparatus includes a clamp that can clamp the flexible display panel from the carrier board and transfer it to the roller, separating the clamping function from the roller's rotational motion and simplifying the overall mechanism.
Solution Approach 2:
The transfer apparatus performs multiple functions including clamping, lifting, and transferring the flexible display panel in a single integrated operation. This self-service approach eliminates the need for separate rolling clamp mechanisms that would otherwise be required to work in coordination with the roller.

AI summary
An apparatus for taking a flexible display panel off includes a roller, a linear motion member, a fastening apparatus and a first driving apparatus. The roller has a circumferential surface which allows a first portion of the flexible display panel to be wound thereon. The linear motion member has a carrying surface. A second portion of the flexible display panel is in contact with the carrying surface. The fastening apparatus is used to fasten the flexible display panel onto the carrying surface of the linear motion member. The first driving apparatus is used to drive the linear motion member to move linearly relative to the circumferential surface, so that the first portion departs from the circumferential surface and moves onto the carrying surface along with the second portion.
