Independent Lower Jig Support for Precise Bonding Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bonding apparatuses apply excessive load to alignment drivers during the attachment of display panel and cover window, potentially causing damage.
Innovation Solution
A bonding apparatus with a support module and alignment module that independently support the lower jig, distributing the load to prevent excessive stress on the alignment driver, using horizontal and vertical movement mechanisms to align and attach materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single support structure is used for the lower jig, then the device complexity is reduced, but the alignment driver experiences excessive load during material attachment
Solution Approach 1:
The support structure is divided into two independent modules: a support module with support shafts and a alignment module with alignment shafts. The support module handles vertical loading while the alignment module handles horizontal positioning, preventing excessive load on the alignment driver during material attachment.
Solution Approach 2:
The support shafts act as intermediaries between the lower jig and the base, providing a dedicated load-bearing path that separates the alignment function from the support function. This intermediary structure protects the alignment driver from direct vertical loads.
2Manufacturing precision
If the support module and alignment module work together, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The system is segmented into functionally independent support and alignment modules. The support module provides stable vertical support while the alignment module provides precise horizontal positioning, allowing each module to be optimized independently while achieving high overall precision.
Solution Approach 2:
Both modules share common components such as the lower jig and base structure, merging the support and alignment functions into a unified system while maintaining functional independence. This reduces overall complexity compared to having completely separate systems.

AI summary
A bonding apparatus includes an upper jig supporting an upper material, a movement module configured to move the upper jig in a vertical direction, a lower jig disposed below the upper jig and supporting a lower material, a support module supporting the lower jig, and an alignment module configured to support the lower jig and to move the lower jig so that the lower material is aligned on a lower side of the upper material, wherein the support module and the alignment module support the lower jig independently of each other.
