LCD Panel Cutting Debris Suction Around the Cutting Wheel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass cutting machines for LCD panels are inefficient in debris collection, leading to increased cleaning time, productivity loss, line scratches, terminal scratches, short circuits, and health risks due to dispersed glass debris, which are not effectively addressed by current suction systems that only capture debris behind the cutting wheel.
Innovation Solution
A debris collection device comprising a debris collection cap with a suction spray head and a debris adsorption tube, equipped with a separator and adjustable airflow, which surrounds the cutting mechanism to capture debris from all directions, reducing the risk of scratches and improving productivity by collecting debris in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a sucking disk is arranged behind the traveling direction of the cutting wheel to adsorb glass debris, then partial glass debris behind the cutting wheel can be adsorbed, but glass debris in other directions cannot be adsorbed
Solution Approach 1:
The suction system is divided into multiple independent suction nozzles positioned at different locations (front, rear, left, right of the cutting wheel), with each nozzle responsible for collecting debris in its specific direction. This segmentation allows comprehensive coverage of all debris dispersion directions while maintaining efficient collection at each position.
Solution Approach 2:
The suction system transitions from a single-point suction (one-dimensional) to a multi-point spatial distribution (three-dimensional). By positioning suction nozzles at front, rear, left, and right positions around the cutting wheel, the system creates a three-dimensional debris collection network that captures debris dispersed in all directions.
2Object-affected harmful factors
If water or mist is sprayed to flush glass debris from the machining area, then the cutting position can be cleaned, but glass debris flows with the water flow and falls on the glass surface causing scratches
Solution Approach 1:
Instead of using water or mist to flush debris (which causes debris to flow and potentially scratch the glass), the system extracts debris directly through suction nozzles positioned around the cutting wheel. This extraction method removes debris in its original position without causing it to flow across the glass surface, thereby preventing scratches while effectively cleaning the machining area.
Solution Approach 2:
The suction nozzles act as an intermediary between the cutting wheel and the debris collection system. Rather than using water as a medium to move debris (which causes the water-debris flow problem), the suction nozzles directly capture and remove debris through negative pressure, eliminating the need for water as an intermediary and preventing water-induced debris migration.
3Device complexity
If no treatment is done during the cutting process, then the cutting machine structure remains simple, but glass debris accumulates and requires extended cleaning time in the next station
Solution Approach 1:
The suction nozzles are positioned around the cutting wheel to perform preliminary debris collection during the cutting process itself. By actively removing debris at the source as it is generated, the system prevents debris accumulation before it reaches the next station, thereby eliminating the need for extended cleaning time later while adding only minimal structural complexity.
