Problem
Existing display panel inspection devices face inefficiencies in precision and cost due to the use of separate drivers and rack and pinion systems, which lead to issues like particle generation, contamination, and backlash.
Innovation Solution
A display panel inspection device featuring a transfer robot and guide rail system that moves probe blocks precisely to predetermined positions, eliminating the need for separate drivers and rack and pinion systems, thereby improving inspection precision and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate drivers and rack and pinion systems are used to move probe blocks, then the inspection device can perform positioning operations, but particle generation and contamination occur leading to reduced inspection precision
Solution Approach 1:
The patent removes the rack and pinion system from the probe block positioning mechanism, extracting the source of particle generation and contamination. The probe blocks are moved directly along guide rails without mechanical engagement components that generate particles, thereby eliminating the harmful factors while maintaining positioning capability
Solution Approach 2:
The patent replaces the mechanical rack and pinion system with a simpler guide rail-based positioning system. This substitution eliminates complex mechanical interactions that generate particles and contamination, while still achieving the required positioning precision for probe block movement
2Manufacturing precision
If separate drivers and rack and pinion systems are used for probe block movement, then positioning can be achieved, but device complexity and cost increase
Solution Approach 1:
The patent extracts and removes the separate driver and rack and pinion components from the positioning system. This simplification reduces device complexity and cost while maintaining positioning precision through the use of guide rails that directly constrain probe block movement paths
Solution Approach 2:
The guide rails serve multiple functions: they guide probe block movement, provide structural support, and define positioning paths. This multi-functionality eliminates the need for separate drivers and rack and pinion systems, reducing overall system complexity while maintaining positioning capabilities
