Flat Display Panel Cutting Apparatus with Chip Blocking Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat display panel cutting apparatuses often cause defects on the light emitting surface due to pits and scratches generated by glass chips during the cutting process.
Innovation Solution
An apparatus with a chip blocking unit and a scrap breaker that operate independently to form a scribing line between the scrap and non-scrap portions of the panel, preventing glass chips from bouncing onto the light emitting surface by using a connection member and driving member to manage the ascending and descending strokes, ensuring the chip blocking unit covers the non-scrap area and the scrap breaker grips the scrap portion effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional cutting apparatus is used to separate the scrap portion from the flat display panel, then the cutting operation can be performed, but glass chips are generated and fall on the light emitting surface causing pits and scratches
Solution Approach 1:
A chip blocking unit is introduced as an intermediary component between the scrap breaker and the light emitting surface. This unit captures and blocks glass chips before they can fall onto the light emitting surface, while allowing the cutting operation to proceed normally. The chip blocking unit acts as a mediator that prevents harmful interaction between the cutting process and the sensitive display panel surface.
Solution Approach 2:
The cutting apparatus is segmented into distinct functional components: the scrap breaker for performing the cutting operation, the chip blocking unit for capturing debris, and the light emitting surface that needs protection. This segmentation allows each component to perform its specific function independently, enabling the cutting operation to proceed while simultaneously protecting the light emitting surface from chip contamination.
2Object-affected harmful factors
If the chip blocking unit is positioned to block glass chips, then the light emitting surface is protected from defects, but the device structure becomes more complex
Solution Approach 1:
The chip blocking unit is integrated with the existing scrap breaker structure rather than being a completely separate system. The connection member and driving member are combined into a unified mechanism that controls both the scrap breaker and chip blocking unit, reducing overall system complexity while maintaining effective chip blocking functionality.
Solution Approach 2:
The driving member serves multiple functions: it controls the ascending and descending motion of the scrap breaker for cutting operations, and simultaneously controls the chip blocking unit to position itself for chip capture. This multi-functionality reduces the need for separate control mechanisms, thereby simplifying the overall device structure while achieving effective protection.
3Manufacturing precision
If the scrap breaker grips the scrap portion firmly to ensure clean separation, then the cutting precision is improved, but the force applied may cause more glass chip generation
Solution Approach 1:
The glass chips generated during the cutting process are converted from a harmful byproduct into a controllable element. The chip blocking unit is strategically positioned to intercept and contain the chips immediately after generation, transforming the harmful scattering of chips into a controlled collection process. This allows the scrap breaker to apply sufficient force for clean separation while the chips are systematically managed rather than contaminating the light emitting surface.

AI summary
An apparatus for cutting a flat display panel prevents a light emitting surface of a flat display panel from being damaged due to a pit or a scratch. The apparatus for cutting a flat display panel includes a stage supporting a rear substrate of the flat display panel, a chip blocking unit disposed to correspond to a non-scrap portion of the flat display panel, and a scrap breaker to grip a scrap portion of the flat display panel that is to be separated from the flat display panel. A scribing line is formed between the scrap portion and a non-scrap portion of the flat display panel.
