Ionizing Dust Removal Assembly for Galvanometer Lens Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser welding devices face issues with dust removal as existing technologies have not addressed the need of periodically cleaning the lens of the galvanometer and other structures due to static electricity, and the risk of non-electrostatic dust (such as welding fumes, welding spatter, and airborne fibers) adhering to and contaminating the lens of the galvanometer cannot be reduced.
Innovation Solution
A dust removal assembly with a nozzle and an ionizing bar, where compressed air is introduced via an air inlet to produce ionic wind to eliminate static electricity and a high-speed air flow to remove non-electrostatic dust, featuring a design that increases flow velocity and facilitates easy mounting and dismounting of the ionizing bar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual cleaning of the galvanometer lens is performed, then dust can be removed, but the device requires periodic maintenance downtime and manual intervention
Solution Approach 1:
The system enables automatic cleaning of the galvanometer lens through a control device that activates the ionizing bar and/or compressed air blowing device without manual intervention. The controller can operate these components automatically during or between welding operations, allowing the system to self-maintain the lens cleanliness and eliminate the need for periodic manual cleaning downtime
2Stability of the object's composition
If the ionizing bar is permanently fixed in the nozzle, then the structure is stable, but maintenance and replacement of the ionizing bar become difficult
Solution Approach 1:
The supporting structure is designed as a segmented, modular assembly where the ionizing bar is installed in a removable manner within the nozzle. This allows the ionizing bar to be easily detached and replaced by opening the nozzle structure, while the overall supporting structure maintains stability during operation. The modular design facilitates maintenance without requiring complete disassembly of the dust removal device
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 dust removal assembly effectively reduces the risk of dust adherence and implements automatic cleaning of the galvanometer lens, ensuring efficient operation by eliminating static electricity and timely removal of non-electrostatic dust.
Implementation Method 1
Ionic wind produced by the ionizing bar can eliminate static electricity of dust in air below the galvanometer
Implementation Method 2
the compressed air is exhausted via the air outlet to form a high-speed air flow which can blow away non-electrostatic dust in a timely manner
