Laser Torch Head Protection System for Direct Workpiece Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective enclosures for laser cutting machines are bulky, costly, and require a pallet shuttle system for loading and unloading workpieces, which increases operation time and financial costs.
Innovation Solution
A protection system that encloses only the laser torch head, allowing direct loading and unloading of workpieces without a pallet shuttle, and incorporates a minimalist design with integrated safety switches and light shields to prevent light reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective enclosure covers the entire laser cutting machine, then safety protection is improved, but the machine size becomes bulky and operation time increases
Solution Approach 1:
The protective enclosure is segmented to cover only the laser torch head area rather than the entire machine. The enclosure includes front, rear, top, and bottom walls that specifically surround the torch head, leaving other areas open for direct workpiece access.
Solution Approach 2:
Protection is applied locally only where the laser beam is generated and where reflection hazards exist (around the torch head), rather than uniformly across the entire machine. This localized approach maintains safety where needed while minimizing overall enclosure volume.
2Reliability
If a protective enclosure covers the entire laser cutting machine, then safety protection is improved, but operation time increases due to pallet shuttle requirements
Solution Approach 1:
The enclosure is divided into front and rear sections with the laser torch head positioned in the rear. The front section remains open to allow direct workpiece loading and unloading, eliminating the need for pallet shuttle systems while maintaining protection in the critical laser area.
3Object-affected harmful factors
If a protective enclosure covers the entire laser cutting machine, then light reflection protection is improved, but device complexity and cost increase
Solution Approach 1:
Light reflection protection is implemented locally around the laser torch head using reflective shields positioned on the front, rear, top, and bottom walls. This targeted approach addresses reflection hazards only in the area where the laser beam is generated, reducing overall system complexity.
4Reliability
If a protective enclosure covers the entire laser cutting machine, then safety protection is improved, but manufacturing cost increases
Solution Approach 1:
The enclosure is segmented into discrete wall sections (front, rear, top, bottom) that can be manufactured separately and assembled around the laser torch head. This modular approach reduces manufacturing complexity and material requirements compared to a full-machine enclosure.
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 solution reduces the overall size of the laser cutting machine, minimizes light reflection, and allows for efficient coil feeding of workpieces, thereby enhancing safety and reducing operational costs while maintaining high-quality surface finishes.
Implementation Method 1
A laser cutting machine features a cutting head generating a laser beam that moves in both of the horizontal dimensions over a workpiece loading onto a table. The focused laser beam is directed to the workpiece, part of which is then melted, burns, and vaporizes away.
Implementation Method 2
The possible random reflection of the laser light may burn the retina of an operator when the laser initially pierces the workpiece. Therefore, coupling a protective enclosure apparatus to a laser cutting machine is essential to the safe operation of the machine.

AI summary
The present application relates to a laser cutting tool with protective enclosure assembly for manipulating a workpiece on a movable platen. The tool includes a frame, a top protection assembly, a middle protection shield, a bottom protection assembly and a laser torch head. The top protection assembly, middle protection assembly, and bottom protection assembly are removably mounted to the frame such that they form a cavity enclosing only substantially the laser torch head.
