Waterproof Cover Isolates Drive Assembly in Ultrasonic Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the LCD display manufacturing process, the existing cleaning technologies face challenges with material wastage and increased costs due to the contamination of cleaning agents with scraps on the drive assembly during the ultrasonic cleaning process, which hinders effective recycling and leads to reduced service life of filter elements.
Innovation Solution
A cleaning apparatus with a waterproof structure is introduced, featuring a locking member and baffle plates that prevent the cleaning agent from contacting the drive assembly, ensuring the agent is not mixed with scraps and facilitating efficient recycling, thereby reducing material wastage and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drive assembly is exposed to the cleaning agent during ultrasonic cleaning, then the cleaning agent can clean the drive assembly, but the cleaning agent becomes contaminated with scraps and cannot be effectively recycled
Solution Approach 1:
The cleaning chamber is segmented into a first cleaning chamber for cleaning the drive assembly and a second cleaning chamber for cleaning the transmission assembly, separated by a partition plate. This segmentation prevents mixing of cleaning agents and scraps between different components, enabling effective recycling of cleaning agents in each chamber while maintaining cleaning effectiveness.
Solution Approach 2:
A water-proof cover is introduced as an intermediary component to isolate the drive assembly from the cleaning agent in the second cleaning chamber. The cover includes a water-proof groove and seal ring to prevent cleaning agent infiltration, allowing the drive assembly to be protected from contamination while still enabling cleaning of the transmission assembly components.
2Productivity
If the cleaning agent contacts the drive assembly, then cleaning can be performed, but filter elements become clogged with scraps and service life is reduced
Solution Approach 1:
The cleaning system is divided into separate chambers with independent filtering systems. The first cleaning chamber has a first filter element and the second cleaning chamber has a second filter element. This segmentation ensures that scraps from different components are filtered separately, preventing cross-contamination and extending the service life of filter elements by reducing clogging from mixed debris.
Solution Approach 2:
The drive assembly is extracted from the cleaning path by covering it with a water-proof cover. This extraction prevents scraps generated by the drive assembly from entering the cleaning agent circulation system, thereby protecting the filter elements from clogging and extending their service life while maintaining cleaning efficiency for other components.
3Loss of substance
If recycling pipes are connected at the gears, then scraps can be washed away, but the recycling system becomes complex and material wastage increases
Solution Approach 1:
The recycling system is segmented into independent recycling paths for each cleaning chamber. The first cleaning chamber has its own recycling pipe and filter element, and the second cleaning chamber has its own recycling pipe and filter element. This segmentation simplifies the overall recycling system by eliminating the need for complex multi-point connections at gears, while reducing material wastage through efficient localized recycling in each chamber.
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 implementation of the waterproof structure effectively blocks the drive assembly from contact with the cleaning agent, enhancing the recycling process and reducing material wastage and costs associated with premature filter clogging and reduced service life.
Implementation Method 1
a waterproof structure, located between the drive assembly and the cleaning assembly, blocking the drive assembly, and preventing a cleaning agent from coming into contact with the drive assembly
Implementation Method 2
when an ultrasonic cleaning method is used, and these characteristics are related to intensity of ultrasonic cavitation. A large surface tension of a liquid does not easily cause cavitation, but when sound intensity exceeds a cavitation threshold, considerable energy is released by a cavitation bubble collapse. This is favorable for cleaning.
