Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The outflow of the adhesive layer during the manufacturing of display devices leads to defects, which existing technologies have not effectively addressed.
Innovation Solution
A dummy removal apparatus and method utilizing a gripper with a lever and stopper mechanism, along with a presser and sensor module, to grip and separate the dummy from the display panel, minimizing the adhesive layer's outflow by vertical removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional dummy removal method is used, then the dummy can be removed from the display panel, but the adhesive layer flows out causing defects
Solution Approach 1:
The presser applies pressure to the display panel before the dummy is fully removed, creating a barrier that prevents adhesive layer outflow during the removal process. This preliminary action of pressing ensures that the adhesive remains contained while the dummy is being separated from the panel
Solution Approach 2:
The presser acts as an intermediary element between the dummy removal process and the adhesive layer. By positioning the presser on the display panel, it mediates the removal process to prevent direct contact between the adhesive layer and the external environment, thus preventing outflow defects
2Reliability
If the lever rotates toward the stopper to grip the dummy, then the dummy can be securely held, but the mechanism complexity increases
Solution Approach 1:
The lever is designed to rotate dynamically toward the stopper during the gripping process. This rotational movement allows the lever to transition from a non-gripping position to a secure gripping position, enabling reliable dummy holding while maintaining a relatively simple mechanical structure compared to fully rigid mechanisms
Solution Approach 2:
The lever utilizes rotational motion in a different dimensional plane to achieve gripping. Instead of linear movement, the lever rotates to bring its end portion into contact with the dummy, providing secure holding through a different spatial approach that simplifies the overall mechanism
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus and method effectively minimize the outflow of the adhesive layer, reducing defects in the manufacturing process of display devices.
Implementation Method 1
a sensor module that detects changes in a distance between the middle body and the lower body. The sensor module may include: a sensor connected to the middle body; and a blocking part having a side connected to the lower body and another side extending toward a light-emitting part and a light-receiving part of the sensor.
Implementation Method 2
the lever may have a rotation range of 0 to 90 degrees. An end portion of the lever and an end portion of the stopper facing each other may have an uneven pattern.
