Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laser processing machines face challenges in achieving quick and precise movement of the processing head due to inertia and vibration issues, which affect the accuracy of laser beam deflection and cutting nozzle positioning, leading to adverse influences on the optical system.
Innovation Solution
A laser processing machine design where the optical system head and nozzle holding head are separately supported by an optical system nozzle support member, allowing for vibration isolation and independent adjustment of the cutting nozzle position, reducing vibration transmission and improving processing accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the processing head is moved quickly and precisely, then processing speed and efficiency are improved, but vibrations are generated that adversely affect the optical system
Solution Approach 1:
The processing head is divided into two separate heads: an optical system head containing the laser beam irradiating unit and a nozzle holding head containing the cutting nozzle. This segmentation isolates the vibration source (nozzle) from the sensitive optical system, allowing quick movement and acceleration without transmitting vibrations to the optical components.
Solution Approach 2:
The cutting nozzle is extracted from the optical system head and placed in a separate nozzle holding head. This extraction removes the vibration-generating component from proximity to the optical system, eliminating the harmful vibration transmission while maintaining processing functionality.
2Speed
If the processing head is made lightweight for quick movement, then acceleration and deceleration are improved, but the structural integrity and vibration isolation become challenging
Solution Approach 1:
Dividing the processing head into separate optical system head and nozzle holding head allows each component to be optimized independently. The nozzle holding head can be made lightweight for quick movement while the optical system head maintains structural integrity, and vibrations are naturally isolated between the two segments.
3Object-affected harmful factors
If the optical system head and nozzle holding head are separately supported, then vibration transmission is reduced, but device complexity increases
Solution Approach 1:
The support structure is segmented into an optical system head support and a nozzle holding head support, allowing independent movement and vibration isolation. This segmentation provides vibration transmission reduction while maintaining manageable complexity through modular design.

AI summary
An optical system head of the laser processing machine includes a focusing optical system configured to deflect and condense an incident laser beam so that a target object to be processed is irradiated and a deflecting direction adjusting unit configured to adjust the direction of deflection of the laser beams about at least two axes perpendicular or substantially perpendicular to each other. A nozzle holding head of the laser processing machine includes a cutting nozzle configured to blow a cutting gas at a site of the target object, at which the laser beam is irradiated, and a nozzle position adjusting unit configured to adjust the position of the cutting nozzle in a top plane parallel or substantially parallel to the target object. The optical system head and the nozzle holding head are separately supported by an optical system nozzle support member configured to selectively advance or retract in three axis directions relative to the target object.
