Conductive Tape Attachment for Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing size of display panels results in unnecessary conductive tape attachment, leading to material waste and prolonged tape peeling operations, which deteriorate productivity.
Innovation Solution
A tape attaching device and method that cuts conductive tape into predetermined lengths and attaches them to specific attachment regions on the display panel, using a guiding unit, cutting unit, attaching unit, peeling unit, and control unit to synchronize and efficiently align and peel the tape, reducing waste and improving productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the conductive tape is attached to the total range of the side edge part of the display panel, then the attachment operation is simplified, but material waste increases and productivity deteriorates due to repeated peeling operations
Solution Approach 1:
The conductive tape attachment process is segmented into multiple attachment regions corresponding to different electrode part locations. The tape is attached only to specific regions where electrode parts are formed, rather than the entire side edge part. This segmentation eliminates the need for repeated peeling operations while maintaining manufacturing simplicity, thereby improving productivity.
2Loss of substance
If the conductive tape is attached only to the component connection range, then material waste is eliminated, but the operation time increases due to repeated tape peeling operations
Solution Approach 1:
The conductive tape is preliminarily attached to all necessary attachment regions in one continuous operation before any peeling occurs. The tape guiding unit feeds the tape continuously while the attaching unit presses it onto multiple attachment regions sequentially. This preliminary action eliminates material waste and avoids repeated peeling operations, thereby reducing operation time.
Solution Approach 2:
The tape attachment operation is performed continuously across multiple attachment regions without interruption or repeated peeling. The tape guiding unit and attaching unit work in coordination to maintain continuous tape feeding and attachment, ensuring the useful action of tape attachment is uninterrupted and efficient.
3Ease of manufacture
If the overall conductive tape is attached onto the total range of the side edge part, then the attachment process is simplified, but unnecessary material is wasted
Solution Approach 1:
The attachment process applies local quality by attaching the conductive tape only to specific attachment regions where electrode parts are formed, rather than uniformly across the entire side edge part. Each attachment region receives tape according to its specific need, eliminating waste of unnecessary material while maintaining process simplicity through automated selective attachment.
