Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser processing machines struggle to discharge sparks and dirt particles produced during the processing of workpieces in a structurally simple and controlled manner, posing risks to operators and machine components.
Innovation Solution
A spark protection device is arranged in the region of the transition from the bridge to the two longitudinal beams, featuring a main deflection surface inclined at an angle of less than 90° to deflect sparks and dirt particles into the processing space, away from the laser processing head, effectively directing them below the workpiece plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a protective hood is arranged around the laser processing head, then operator and component protection from sparks is improved, but device complexity increases
Solution Approach 1:
The invention extracts the harmful sparks and dirt particles from the processing area by deflecting them away from critical components and the operator. The deflection surface separates the harmful factors from the protected zones, allowing protection without enclosing the entire processing head in a complex hood structure.
Solution Approach 2:
The deflection surface acts as an intermediary element between the spark generation zone and the protected areas. It intercepts and redirects sparks and particles into a controlled discharge path, mediating between the harmful process and the components/operator that need protection.
2Object-generated harmful factors
If an extraction chamber with particle chute is provided below the work area, then particle removal is improved, but device complexity increases
Solution Approach 1:
The invention extracts particles from the processing area using a simple deflection surface that redirects them along gravity into a collection area below the workpiece plane. This eliminates the need for complex extraction chambers and particle chutes while achieving effective particle removal.
Solution Approach 2:
The deflection surface utilizes gravity as a natural force to guide particles downward into the collection area. The system serves itself by using the inherent gravitational field rather than requiring complex mechanical extraction mechanisms, achieving particle removal with minimal additional components.
3Device complexity
If a deflection surface is inclined at a small angle, then structural simplicity is improved, but spark deflection effectiveness decreases
Solution Approach 1:
The invention optimizes the inclination angle parameter of the deflection surface to achieve the optimal balance between structural simplicity and deflection effectiveness. By carefully selecting the angle within a specific range, the system maintains a simple geometric form while ensuring sparks are effectively redirected away from critical areas.
