Cache Device Multi-Directional Air Blowing for LCD Screen Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cache devices in electronic glass production lines, such as LCD screen manufacturing, face inefficiencies in maintaining cleanliness due to limited air flow direction and difficulty in reaching corners for cleaning, leading to incomplete dust removal and the need for frequent manual deep cleaning.
Innovation Solution
The cache device incorporates multiple air blowing and exhaust mechanisms with adjustable nozzles and a controller for automatic operation, allowing continuous cleaning parallel to the substrate plane and enabling deep cleaning by varying air stream directions, reducing manual intervention and enhancing cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple air blowing means are added to achieve comprehensive cleaning coverage, then cleaning effectiveness is improved, but device complexity increases
Solution Approach 1:
The cache device is divided into multiple cleaning zones with separate blowing means positioned on different side walls (first blowing means on second side wall, second blowing means on third side wall, third blowing means on fifth side wall). Each blowing means independently cleans specific areas, ensuring comprehensive coverage while maintaining manageable system complexity through modular segmentation.
Solution Approach 2:
Air streams are introduced from multiple spatial dimensions (different side walls of the frame) rather than a single direction. The first blowing means blows toward the opening, the second blowing means blows into the interior from an adjacent side wall, and the third blowing means provides additional dimensional coverage, creating three-dimensional cleaning coverage that eliminates blind spots in corner areas.
2Reliability
If air stream pressure is increased to improve dust removal capability, then cleaning effectiveness is improved, but risk of damaging cached items increases
Solution Approach 1:
Different blowing means operate at different pressure levels suited to their specific cleaning tasks. The first blowing means operates at lower pressure for general cleaning, while the second and third blowing means can operate at higher pressures (not less than the first blowing means pressure) specifically targeted at corner areas and hard-to-reach regions, providing localized high-pressure cleaning only where necessary to avoid damage to cached items.
Solution Approach 2:
The controller enables periodic operation of the second and third blowing means during idle periods when no cached items are present, allowing high-pressure cleaning of the interior and corners without risk of damaging items. During active operation with cached items present, these high-pressure means remain inactive, thus protecting items while maintaining effective dust removal capability when needed.
3Reliability
If continuous operation of blowing means is maintained to ensure constant cleaning, then cleaning effectiveness is improved, but energy consumption increases
Solution Approach 1:
The controller is configured to activate the second and third blowing means in advance during idle periods before cached items are loaded into the cache device. This preliminary high-pressure cleaning removes accumulated dust and particles from corners and interior surfaces before items are placed, ensuring clean conditions without requiring continuous operation during active storage when items are present.
Solution Approach 2:
The first blowing means operates continuously at lower pressure to maintain basic cleaning effectiveness and remove loose particles, while the more energy-intensive second and third blowing means operate periodically during idle periods. This combination ensures continuous useful cleaning action while optimizing energy consumption by avoiding unnecessary high-pressure operation when cached items are present.
4Reliability
If manual deep cleaning is performed frequently to maintain cleanliness, then cleaning thoroughness is improved, but production time is lost
Solution Approach 1:
The cache device is equipped with automated blowing means that perform self-cleaning of their interior surfaces, corners, and support bracket areas without requiring manual intervention. The controller automatically activates the second and third blowing means during idle periods to clean the interior, and the exhaust means removes dislodged particles, enabling the device to maintain itself without stopping production for manual deep cleaning operations.
Solution Approach 2:
The system performs preliminary cleaning of corners and interior surfaces during idle periods before cached items are loaded or during transitions between batches. This preliminary action removes accumulated dust and particles that would otherwise require manual deep cleaning, significantly reducing the frequency and duration of manual cleaning interruptions to production.
