Circulating Band Beam Catcher for Laser Cutting Energy Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beam-catching devices for processing machines do not effectively absorb high-energy cutting beams, leading to incomplete absorption, beam reflections, and adherence of slag, dust, and burn-off residue, which can cause damage and local heating.
Innovation Solution
A circulating band made of a heat-conductive material, such as metal, is positioned within the beam-catching device to absorb and distribute the cutting beam's energy, preventing overheating and damage, while its structured surface enhances energy absorption and the band's design allows for continuous movement and removal of residues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a stationary housing is used to catch the cutting beam, then the beam can be contained, but energy absorption is incomplete and local heating occurs
Solution Approach 1:
The patent applies the dynamics principle by replacing the stationary housing with a circulating band that continuously moves through the beam-catching device. This dynamic element ensures constant motion relative to the cutting beam, preventing energy concentration at any single location and enabling continuous energy absorption without local heating accumulation.
Solution Approach 2:
The patent changes the physical state and motion parameters of the beam-catching element. By transforming from a static housing to a moving circulating band, the system alters the temporal and spatial parameters of energy interaction, allowing the beam to continuously strike fresh surfaces and distribute energy absorption over time and space.
2Reliability
If a stationary housing is used to catch the cutting beam, then the beam can be contained, but damage to the device occurs
Solution Approach 1:
The circulating band's continuous motion prevents stationary damage accumulation. By constantly moving through the housing, the band ensures that no single point remains exposed to the cutting beam indefinitely, thereby preventing localized damage and extending device reliability.
Solution Approach 2:
The patent extracts the vulnerable stationary housing structure and replaces it with a moving circulating band that can be easily replaced or maintained. This separation allows the beam-catching function to be decoupled from the fixed housing, reducing the housing's exposure to harmful beam effects.
3Loss of energy
If a stationary housing is used to catch the cutting beam, then the beam can be contained, but slag and dust adhere to the device
Solution Approach 1:
The continuous motion of the circulating band prevents slag and dust from adhering to stationary surfaces. The constant movement disrupts the accumulation process, and residues are carried away with the band as it circulates, maintaining cleaner operational conditions.
Solution Approach 2:
The circulating band acts as a removable carrier that extracts residues from the beam path. By continuously moving through the housing, the band carries away accumulated slag and dust, separating the residue removal function from the fixed housing structure.
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 achieves high energy absorption, reduces heating of workpiece supports, prevents damage to the device, and ensures efficient removal of residues, maintaining a stable processing environment.
Implementation Method 1
a solid medium which moves relative to the opening and crosses the cutting beam is provided in the housing... High energy absorption of the cutting beam is achieved
Implementation Method 2
the band to be made of a material which is a good conductor of heat. As a result, the energy received in the band can be distributed and drawn off quickly and uniformly
Implementation Method 3
a structured surface is preferably provided in the case of a planar band, which structured surface, preferably dulled and slightly etched, has an embossed structure or a corrugated or fluted surface. As a result, the surface is enlarged for the energy absorption. In addition, spreading of the striking cutting beam can be achieved, since a diffuse beam reflection is effected

AI summary
A beam-catching device is provided for a cutting-beam processing machine configured to deliver a cutting beam to a workpiece. The beam-catching device includes a housing which has a line-like opening pointing toward the cutting beam, the cutting beam discharging from the underside of the workpiece during processing of the workpiece and entering the housing through the opening, and a solid medium disposed within the housing and configured to move relative to the opening of the housing in a direction crossing the cutting beam in order to absorb energy.
