Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting machines, and in particular relates to a protective device for a laser cutting machine. Background Art

[0002] Laser cutting is achieved by applying high-power density energy generated by laser focusing. Under computer control, the laser is discharged through pulses, thereby outputting controlled repetitive high-frequency pulsed lasers, forming a beam of a certain frequency and a certain pulse width. The pulsed laser beam is transmitted and reflected through the optical path and focused on the surface of the object to be processed through a focusing lens group, forming a fine, high-energy density spot. The focal spot is located near the surface to be processed, and the processed material is melted or vaporized at an instant high temperature. Under computer control, the laser processing head and the processed material are continuously moved relative to each other according to a pre-drawn pattern, so that the object can be processed into the desired shape. A large amount of exhaust gas will be generated during laser cutting, which can cause harm to the human body. In this case, an exhaust gas treatment device is generally required to be installed on the laser cutting machine, and the exhaust gas generated is sucked into the exhaust gas treatment box through an air suction device, but there are the following defects:
