Solution Overview
Problem
Conventional laser processing systems face challenges with permanently connected focusing optics and lens inserts, leading to difficulties in aligning and replacing focusing optical systems, resulting in exposure to ambient atmosphere and inaccuracies in digital manual adjustments.
Innovation Solution
A head assembly for a laser processing system with a slidingly adjustable focusing lens assembly, secured by a monolithic cover plate and pivot arms, allowing for secure and remote control of lens displacement along the beam path, enabling easy replacement and precise alignment of focusing optics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If focusing optics and lens inserts are permanently connected, then structural simplicity is improved, but alignment capability and replaceability deteriorate
Solution Approach 1:
The terminal head is divided into separate functional modules: a fixed mount structure, a movable focusing optics assembly, and replaceable lens inserts. The focusing optics assembly can be independently adjusted relative to the beam path, and lens inserts can be swapped without replacing the entire assembly. This segmentation enables both structural simplicity and adaptability.
2Adaptability or versatility
If separate focusing optical systems and lens inserts are used with swappable adaptor plates, then replaceability is improved, but device complexity and exposure to ambient atmosphere worsen
Solution Approach 1:
A single universal mount structure accommodates multiple lens insert sizes and types through standardized interfaces. The focusing optics assembly can work with different lens inserts without requiring separate adaptor plates, reducing overall device complexity while maintaining replaceability.
Solution Approach 2:
Lens inserts are nested within the focusing optics assembly, which itself is nested within the terminal head housing. This nested arrangement allows compact integration of multiple components and eliminates the need for separate adaptor plates, reducing device complexity while maintaining replaceability.
3Ease of operation
If direct digital manual adjustment is used, then ease of operation is improved, but adjustment precision deteriorates
Solution Approach 1:
The manual adjustment mechanism is replaced with an automated motorized drive system that uses electronic signals for precise positioning of the focusing optics assembly. This substitution maintains ease of operation through electronic control while dramatically improving adjustment precision through digital feedback and control algorithms.
