Bonding Device for Irregular Curved Cover Plate on Flexible Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bonding devices are unable to effectively attach a 3D curved cover plate with an irregular shape to a flexible screen, as they can only bond with fixed curved cover plates and not those with irregular shapes.
Innovation Solution
A bonding device comprising a first and second bonding body, a pressing body, and a driving mechanism, with vacuum adsorption and telescopic connectors, is used to securely attach a curved cover plate with a flat area and arc hook areas to a flexible screen, allowing for precise alignment and improved bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional bonding devices are used, then fixed curved cover plates can be bonded, but irregular shaped curved cover plates cannot be effectively attached
Solution Approach 1:
The bonding device is divided into multiple bonding bodies (first bonding body, second bonding body, and third bonding body) that can independently move and adapt to different regions of the irregular shaped cover plate. Each bonding body has pressing walls with specific geometries (curved walls for arc hook areas, flat walls for flat areas) that can be positioned and pressed separately, allowing the device to accommodate complex irregular shapes that conventional single-unit bonding devices cannot handle
Solution Approach 2:
The bonding device employs a driving mechanism that enables the bonding bodies to move dynamically between adjacent and separated positions. This dynamic capability allows the bonding bodies to adapt their configuration to match the irregular geometry of the cover plate during the bonding process, providing reliable attachment across varying surfaces that static conventional devices cannot achieve
2Adaptability or versatility
If bonding bodies are moved adjacent to each other, then irregular shapes can be accommodated, but device complexity increases
Solution Approach 1:
Each bonding body is designed with multi-functional pressing walls that can handle different geometric regions (curved pressing walls for arc hook areas, flat pressing walls for flat areas). The bonding bodies themselves serve multiple functions: they provide pressing force, accommodate different shapes through their movable design, and can be independently controlled by the driving mechanism. This multi-functionality reduces the need for entirely separate components for each bonding task, thereby managing device complexity while maintaining high adaptability to irregular shapes

Function Achieved in This Case
The device ensures strong and effective attachment of the curved cover plate with an irregular shape to the flexible screen, enhancing the bonding effect by using vacuum adsorption and controlled movement of the bonding bodies to match the shape of the arc hook areas.
