Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to an anti-flash structure for laser cutting machines. Background Art

[0002] A laser cutting machine is a device that uses a laser beam to cut materials. This device uses a laser light source to focus a high-energy-density laser beam onto a small area, causing the material to instantly melt, vaporize, or burn at the focal point, thereby achieving the desired effect. Because laser cutting machines can achieve high-precision and detailed cutting, they are widely used. However, laser cutting machines typically generate intense laser radiation during operation. To ensure the safety of operators and the surrounding environment, laser cutting machines must be equipped with anti-flash features to prevent damage to the human eye through reflection or scattering of the laser beam.
