Display Panel Dispensing Device Scanning and Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dispensing devices for display panels lack monitoring capabilities, resulting in suboptimal dispensing conditions and low product yield due to the absence of real-time monitoring and calibration, leading to inefficiencies in bonding processes.
Innovation Solution
A dispensing method and device that scans the outline of the display panel to obtain dispensing parameters, determines if these parameters meet preset conditions, and only dispenses glue when the conditions are met, including calibration to ensure the panel is in a horizontal state and identification of anchor points for accurate dispensing paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time monitoring and calibration are added to the dispensing device, then manufacturing precision and product yield improve, but device complexity increases
Solution Approach 1:
The system performs preliminary scanning and calibration actions before the actual dispensing process. The outline of the display panel is scanned in advance to obtain position information, and the horizontal state is calibrated before glue dispensing, ensuring that all preparatory measurements and adjustments are completed beforehand to guide the subsequent precise dispensing operation
Solution Approach 2:
The system implements feedback control by scanning the display panel outline, determining whether the obtained parameters meet preset dispensing conditions, and only proceeding with dispensing when conditions are satisfied. This closed-loop feedback mechanism ensures that dispensing operations are performed only when proper conditions are met, thereby improving manufacturing precision
2Reliability
If monitoring and condition checking are implemented before dispensing, then product yield improves, but productivity decreases due to additional process steps
Solution Approach 1:
The system performs preliminary scanning and condition verification before dispensing, but these actions are integrated into the automated workflow. By pre-determining whether dispensing conditions are met through automated scanning and parameter checking, the system avoids performing unnecessary dispensing operations that would waste materials and time, thereby improving overall product yield
Solution Approach 2:
The system performs self-verification by automatically scanning the display panel, determining whether parameters meet dispensing conditions, and making decisions about whether to proceed with dispensing. This automated self-service mechanism reduces the need for manual inspection and intervention, maintaining productivity while improving reliability
