Rotatable ID Reader for TFT-LCD Panel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the manufacturing of TFT-LCDs, the inflexible mounting of ID readers requires frequent and time-consuming adjustments of the base table to accommodate varying panel ID attachment positions, affecting manufacturing efficiency.
Innovation Solution
The ID reader features a rotatable base and connecting frame, allowing for adjustable angles through threaded couplings and arc rails, enabling convenient alignment with panel IDs of different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the reader is mounted in a fixed rigid way, then the mounting structure is simple and stable, but the reader angle cannot be adjusted and frequent base table adjustments are required
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed rigid mounting structure into a multi-level rotatable structure. The reader body can rotate around a first axial line relative to the support frame, and the support frame can rotate around a second axial line relative to the base. This dynamic structure enables continuous angle adjustment of the reader without requiring base table adjustments, resolving the contradiction between adaptability and structural complexity.
2Adaptability or versatility
If the base table angle is adjusted to aim the scanning head, then the reader can scan panel IDs at different positions, but the operation time increases and manufacturing efficiency decreases
Solution Approach 1:
The dynamic rotatable mounting structure allows the reader to independently adjust its scanning angle by rotating the reader body around the first axial line and the support frame around the second axial line. This eliminates the need for time-consuming base table adjustments while maintaining comprehensive scanning coverage, thus reducing adjustment operation time without sacrificing adaptability.
Solution Approach 2:
The patent segments the adjustment function into two independent rotational degrees of freedom: one for adjusting the reader body angle and another for adjusting the support frame angle. This segmentation allows precise targeting of panel IDs at various positions without requiring complete base table repositioning, reducing adjustment time while maintaining scanning coverage.
3Ease of operation
If multiple adjustments are required to aim the scanning head, then the reader can adapt to different panel ID positions, but the manufacturing efficiency is affected
Solution Approach 1:
The multi-axis rotatable structure provides continuous and independent adjustment capability for the reader angle. Operators can directly position the scanning head at the required angle by rotating the reader body and support frame, eliminating the need for multiple iterative adjustments. This improves ease of operation while maintaining productivity by reducing the total adjustment time and number of adjustment operations required.
