Laser Cleaning Head Dustproof Nozzle for Lens Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laser cleaning machine lenses are prone to contamination and burnout due to dust accumulation, leading to increased replacement costs and reduced efficiency.
Innovation Solution
A dust removal system comprising a filter, gas pump, gas pipe, and dustproof nozzle is integrated into the laser cleaning head, creating a positive pressure environment that prevents dust from reaching the lens, using a pipeline assembly and seal ring for effective dust isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If laser cleaning machine operates continuously, then productivity increases, but lens contamination and burnout risk increases
Solution Approach 1:
The system performs preliminary protective action by establishing a positive pressure protective environment around the lens before dust contamination can occur. The gas pump continuously supplies filtered air to maintain positive pressure, preventing dust from reaching the lens surface during the cleaning operation.
Solution Approach 2:
Filtered air acts as an intermediary substance between the dust-laden environment and the lens. The gas pump delivers this intermediary medium to create a protective barrier, while the dustproof nozzle directs it precisely where needed to shield the lens without interfering with the laser cleaning process.
2Reliability
If lens replacement frequency increases, then contamination prevention improves, but operational costs and time loss increase
Solution Approach 1:
The system provides self-service protection by automatically maintaining a clean environment around the lens through continuous operation of the gas pump and filter. The positive pressure system automatically prevents dust accumulation without requiring manual intervention or lens replacement, making the system self-sustaining in protecting the lens.
3Reliability
If positive pressure protection is implemented, then lens protection improves, but system complexity increases
Solution Approach 1:
The system extracts and removes dust particles from the air stream before the air reaches the lens. The filter component specifically extracts dust from the gas flow, while the dustproof nozzle extracts and directs the cleaned air precisely where it is needed, creating protection without requiring complex multi-component systems.
4Reliability
If dustproof nozzle design is optimized, then dust isolation effectiveness improves, but manufacturing complexity increases
Solution Approach 1:
The dustproof nozzle applies local quality by concentrating the protective gas flow precisely at the lens interface where it is most needed. The nozzle design directs filtered air specifically toward the lens area rather than dispersing it broadly, creating effective local protection while maintaining a simple overall system design that is easy to manufacture.
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 system effectively prevents lens contamination, prolongs lens lifespan, reduces replacement frequency, and lowers operational costs by maintaining a clean lens environment.
Implementation Method 1
gas passes through the filter to filter the dust in the air
Implementation Method 2
enters the gas pump for pressurization, then reaches the interior of the laser cleaning head by means of the gas pipe
Implementation Method 3
gas passes through the filter to filter the dust in the air and enters the gas pump for pressurization, then reaches the interior of the laser cleaning head by means of the gas pipe, and is blown out of the dustproof nozzle gas outlet by blowing on both sides of the pipeline assembly to form an internal positive pressure
