Laser Processing Head Access Layout for Dirt-Sealed Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laser processing heads face issues with dirt particles entering the housing through access openings, leading to thermal effects and reduced optical component lifespan, and require complex disassembly for maintenance, which is not intuitive and can result in unauthorized access.
Innovation Solution
The laser processing head features an access opening on the mounting surface, reducing dirt entry and allowing for sealed operation, with a hinged mounting cover for safe and easy access to optical components without removing the head from the carrier, and a carrier that shields the access cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If access openings are provided on the front or lateral surfaces of the housing, then optical components can be accessed for servicing, but dirt particles enter the housing causing thermal effects and reducing optical component lifetime
Solution Approach 1:
The access opening is relocated from the front or lateral surfaces to the mounting surface (rear side) of the housing, changing the spatial dimension of access. This allows servicing while the front and lateral surfaces remain sealed against dirt contamination during operation.
Solution Approach 2:
The housing is divided into functional zones: the mounting surface contains the access opening for maintenance, while the front and lateral surfaces are sealed to prevent contamination. This segmentation allows simultaneous achievement of accessibility and protection.
2Ease of operation
If access openings are provided on exposed surfaces of the housing, then optical components are easily accessible, but unauthorized access and unintentional opening occur leading to drastic consequences
Solution Approach 1:
By moving the access opening to the mounting surface (rear side) of the housing, the opening is positioned in a location that is not intuitively accessible during normal operation. This reduces the risk of unauthorized or unintentional access while maintaining serviceability for authorized personnel.
3Ease of repair
If horizontal modules are disassembled to access optical components, then components can be removed, but the interfaces and access openings become heavily soiled requiring thorough cleaning
Solution Approach 1:
The access opening is positioned on the mounting surface rather than on front or lateral surfaces. This allows optical components to be accessed and removed without exposing the sealed front and lateral surfaces to contamination, eliminating the need for thorough cleaning after maintenance.
4Adaptability or versatility
If the laser processing head is mounted on a carrier, then it can be supported and moved during processing, but the mounting surface is the only area available for customized design
Solution Approach 1:
By placing the access opening on the mounting surface (rear side), the front and lateral surfaces are freed from functional constraints and can be used for customized design, branding, or additional features without interfering with the access functionality.

AI summary
A laser processing head includes a housing including a mounting surface for mounting the laser processing head on a carrier; a plurality of optical components arranged within the housing; and an access opening formed in the housing for removing or inserting at least one first optical component among the optical components, the access opening being formed in the mounting surface.
