Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser processing systems are limited in their ability to efficiently and flexibly direct a laser beam to multiple processing positions without the restriction of optical fibers, which hampers the movement and positioning of processing tools.
Innovation Solution
A laser processing system comprising a laser oscillator, a laser beam emitting tool supported by a first robot, and a laser processing tool supported by a second robot, where the laser beam emitting tool emits a laser beam to the processing tool, allowing for independent movement and positioning without optical fiber constraints, and a robot control unit that manages the emission timing and positioning of the laser beam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single laser oscillator with light duct and guide means is used to supply laser beam to two processing tools, then the system structure is simplified and cost is reduced, but the movement and positioning flexibility of processing tools is restricted due to optical fiber constraints
Solution Approach 1:
The patent divides the laser beam supply system into two independent paths: one from the laser oscillator to the first processing tool, and another from the first processing tool to the second processing tool. This segmentation allows each tool to move independently without being constrained by a single optical fiber connection, resolving the contradiction between simplified structure and movement flexibility.
Solution Approach 2:
The first processing tool acts as an intermediary that receives the laser beam and then emits it toward the second processing tool. This intermediary approach enables the second tool to receive laser energy without a direct optical fiber connection to the oscillator, thereby achieving movement flexibility while maintaining system simplicity.
2Reliability
If optical fibers are used to connect laser oscillator to processing tools, then laser beam transmission is stable, but the positioning and repositioning of processing tools becomes restricted and slow
Solution Approach 1:
The patent segments the laser transmission path so that the first tool maintains a stable optical fiber connection to the oscillator, while the second tool receives beams through the first tool without direct fiber constraints. This enables rapid repositioning of the second tool without compromising transmission stability for the first tool.
Solution Approach 2:
The system dynamically adapts the laser beam path: the first tool can receive beams directly when positioned, and then emit beams to the second tool which can move freely. This dynamic configuration allows stable transmission when needed and rapid repositioning when required.
3Adaptability or versatility
If multiple laser oscillators are used to supply laser beams to multiple processing tools independently, then each tool can be positioned and moved freely, but the system complexity and cost increase
Solution Approach 1:
The first processing tool serves multiple functions: it acts as a processing tool for its own tasks and simultaneously functions as a laser beam emitter for the second tool. This multi-functionality reduces the need for separate laser oscillators for each tool, thereby maintaining positioning freedom while reducing system complexity.
Solution Approach 2:
Instead of using a separate laser oscillator for the second tool, the system uses the first tool as a 'copy' or intermediary emitter. The laser beam characteristics are copied from the first tool's emission to provide the second tool with independent positioning capability without adding a complete second oscillator system.
