Adjustable-Focus Laser Galvanometer for Deep Surface Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laser cleaning scanners have a fixed focal depth, limiting their flexibility and applicability, especially when cleaning objects with deep surfaces, as the distance between the laser exit port and the surface to be cleaned is fixed.
Innovation Solution
An adjustable focus laser cleaning galvanometer is developed, featuring an adjustable lens set with movable lenses that allow for axial adjustment of the focal length, enabling flexible focal depth and power levels for different objects, combined with a galvanometer that can swing for scanning and a ranging sensor for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed focal length lens is used in the laser cleaning scanner, then the structure is simple and easy to manufacture, but the focal depth cannot be adjusted, limiting the scope of application especially for objects with deep surfaces
Solution Approach 1:
The patent applies the dynamics principle by making the lens set adjustable rather than fixed. The lens set can move along the optical path to change the focal depth dynamically, allowing the same device to adapt to different cleaning depths and object types, thus resolving the contradiction between adaptability and structural simplicity
Solution Approach 2:
The patent implements universality by designing a lens set that can provide multiple focal depths through adjustment. This single adjustable lens set replaces the need for multiple fixed lenses, enabling the device to handle various cleaning scenarios (different depths and object types) with one component, thereby expanding scope of application without proportionally increasing complexity
2Adaptability or versatility
If the focal depth is fixed, then the laser exiting port distance to surface is fixed, but this limits cleaning capability for deep surfaces
Solution Approach 1:
The lens set is designed to be movable along the optical axis, allowing dynamic adjustment of focal depth. This enables the operator to adapt the focal point to match different surface depths, transforming a static fixed-distance system into a dynamic adjustable system that can handle both shallow and deep cleaning tasks
