Laser Beam Reflector Layout for Wider Scanning Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser processing apparatuses have limited scanning line widths, making it difficult to achieve a wide processing range.
Innovation Solution
The apparatus includes a scanner unit and a reflector unit with sub-reflector units that adjust and reflect the laser beam, allowing for expansion of the scanning line width by shifting and inclining the optical path, enabling processing across a wider range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a conventional scanner is used to determine the scanning line of a laser beam, then the scanning line width is limited, but the device complexity is reduced
Solution Approach 1:
The reflector unit is divided into multiple sub-reflector units (first sub-reflector unit, second sub-reflector unit, etc.), each responsible for shifting the optical path in different directions. This segmentation allows the system to achieve wide scanning coverage through coordinated action of multiple simpler components rather than requiring a single complex scanner
Solution Approach 2:
The reflector unit acts as an intermediary component between the scanner and the processing target. It receives the laser beam from the scanner and redirects it through multiple reflections to expand the scanning line width, thereby decoupling the scanner's limited native width from the final processing range
2Adaptability or versatility
If the scanner adjusts the optical path in only one direction, then the device complexity is reduced, but the processing range is limited
Solution Approach 1:
The system transitions from single-direction optical path adjustment to multi-directional adjustment by introducing sub-reflector units that shift the beam in different directions (first direction, second direction, third direction). This dimensional expansion of control allows the scanner to cover a wider processing area while maintaining a relatively simple scanner structure

Function Achieved in This Case
This configuration allows for effective processing across a broader area, even when the scanning width of the scanner is limited, enhancing the range of applications in laser processing.
Implementation Method 1
a reflector unit disposed in an optical path of a laser beam adjusted by the scanner unit, where the reflector unit reflects the laser beam adjusted by the scanner
Data Source
AI summary
A laser processing apparatus includes a laser source which generates a laser beam; a scanner unit disposed in an optical path of the laser beam from the laser source and which adjusts the optical path of the laser beam from the laser source in a first direction or in a second direction different from the first direction; and a reflector unit disposed in an optical path of the laser beam adjusted by the scanner unit and which reflects the laser beam adjusted by the scanner unit, where the reflector unit includes a first sub-reflector unit which shifts an optical path of the laser adjusted by the scanner unit in the first direction, and a second sub-reflector unit which shifts an optical path of the laser beam adjusted by the scanner unit in a third direction opposite to the first direction.
