Display Panel Bonding Stage With Dual-Support Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bonding apparatuses for display panels and circuit boards suffer from issues such as deflection and eccentricity due to the use of a single shaft support, leading to inaccurate alignment and bonding precision.
Innovation Solution
A bonding apparatus with a dual support system, featuring a main support portion and a sub-support portion that maintains a constant distance while rotating, allowing for precise alignment and bonding through a combination of linear and curved movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single shaft support is used, then the device complexity is reduced, but manufacturing precision deteriorates due to deflection and eccentricity
Solution Approach 1:
The support structure is divided into multiple independent shafts (first shaft and second shaft) instead of using a single shaft. Each shaft independently supports the stage, distributing the loading and eliminating the deflection and eccentricity problems associated with a single shaft design. This segmentation approach maintains reasonable device complexity while significantly improving alignment precision.
2Device complexity
If a single shaft support is used, then the device complexity is reduced, but bonding precision deteriorates due to deflection and pushing
Solution Approach 1:
The support structure is divided into multiple independent shafts (first shaft and second shaft) instead of using a single shaft. Each shaft independently supports the stage, distributing the loading and eliminating the deflection and eccentricity problems associated with a single shaft design. This segmentation approach maintains reasonable device complexity while significantly improving alignment precision.
3Manufacturing precision
If multiple support portions are added, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The support structure is divided into multiple independent shafts (first shaft and second shaft) instead of using a single shaft. Each shaft independently supports the stage, distributing the loading and eliminating the deflection and eccentricity problems associated with a single shaft design. This segmentation approach maintains reasonable device complexity while significantly improving alignment precision.
Solution Approach 2:
The first shaft and second shaft are combined to form a unified support system that works together to support the stage. Both shafts are integrated into the overall apparatus structure, sharing the support function and providing mutual stability. This merging approach allows the system to achieve high precision while controlling complexity through coordinated operation of multiple components.

AI summary
A bonding apparatus for a display apparatus includes a first support unit on which a first panel is mounted and a second support unit on which a second panel is bonded to the first panel is mounted, wherein the second support unit includes a stage on which the second panel is mounted, a main support portion arranged below the stage and supporting the stage, wherein the stage is rotated with the main support portion as a rotation axis as the main support portion is rotated, a sub-support portion connected below the stage and supporting the stage, wherein the sub-support portion slidingly moves on a plane which is perpendicular to the rotation axis as the stage is rotated, and a base plate supporting the main support portion and the sub-support portion.
