Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the OLED device evaporation process, the existing methods for aligning and measuring the clamping blocks in the clamping assembly are inaccurate and time-consuming, leading to misalignment and inefficiencies due to the use of traditional measurement tools like steel rulers and feeler gauges, which result in significant measurement errors and difficulty in detecting slight changes in block positions.
Innovation Solution
A loading jig with a plate-like body and elastic membranes connected to a signal converter is introduced, allowing for precise measurement and adjustment of clamping block pressure, featuring slots for secure clamping, scale patterns for intuitive positioning, and a display screen for real-time pressure feedback, enabling accurate alignment and adjustment of clamping blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional steel rulers and feeler gauges are used to measure clamping block positions and distances, then the measurement process is simple and low-cost, but the measurement accuracy is poor with millimeter-order errors occurring
Solution Approach 1:
The patent replaces traditional mechanical measurement tools (steel rulers, feeler gauges) with a vision measurement system using CCD cameras and image processing. This substitution eliminates the deformation issues and human error associated with mechanical tools, achieving high-precision measurement of clamping block positions and distances without direct physical contact.
Solution Approach 2:
The patent creates a digital copy of the clamping block positions through image capture and processing. By photographing the scale patterns on the bearing platform and mask, the system generates digital representations that can be precisely measured and analyzed, replacing physical measurement with optical copying and digital analysis.
2Measurement precision
If traditional measurement methods are used for clamping blocks, then the equipment structure remains simple, but slight changes in block positions cannot be detected and measured
Solution Approach 1:
The patent replaces mechanical measurement with optical-vision-based measurement using CCD cameras. This allows for non-contact, high-resolution detection of clamping block positions, enabling the system to detect slight changes that would be imperceptible to mechanical tools or human senses.
Solution Approach 2:
The patent implements a feedback mechanism where the vision system continuously monitors clamping block positions and provides real-time data. This feedback loop enables dynamic adjustment and precise control of clamping block positions, allowing operators to detect and correct slight position changes immediately.
3Reliability
If clamping assembly components are checked and adjusted regularly, then alignment accuracy is maintained, but more time and cost are required for maintenance
Solution Approach 1:
The patent incorporates scale patterns on the bearing platform and mask during the manufacturing stage, creating built-in reference markers. These pre-established markers enable quick position verification without requiring complex measurement setups, allowing rapid checking of clamping block alignment during maintenance.
Solution Approach 2:
The patent uses image capture to create digital copies of the clamping assembly state for analysis. By photographing the scale patterns and comparing them against reference data, the system can quickly assess alignment accuracy without physical measurement, significantly reducing maintenance time while maintaining reliability.
