Problems solved by technology

In the process of adjusting the width of the laser beam, because the width of the beam changes, the brightness of the spot projected on the workpiece surface changes. For example, when the width of the beam becomes wider, the brightness of the spot becomes dim and blurred, making the operator Can't see clearly; when the width of the ray narrows, the brightness of the spot becomes bright and dazzling, which makes the operator's eyes suffer a certain degree of damage, and finally affects the operator's observation

Abstract

The laser emitting equipment includes one casing, one laser emitting assembly including one laser source and one circuit connected to the laser source, one laser focusing assembly, one laser scattering assembly, one regulating device to regulate the interval between the laser emitting assembly and the laser focusing assembly and one current regulating mechanism connected to the circuit. When the regulating device is operated to regulate the interval between the laser emitting assembly and the laser focusing assembly and to change the width of the laser beam, the current regulating mechanism is regulated to change the current to the laser source and thus the brightness of the laser beam. Therefore, the laser spot projected to the surface of the workpiece has stabilized brightness for easy observation. The present invention also discloses one kind of cutting machine with the laser emitting equipment.

Description

technical field [0001] The invention relates to a laser emitting device, especially a laser emitting device with adjustable laser beam width; the invention also relates to a cutting machine with the laser emitting device. Background technique [0002] The US patent specification US2001049988A1 discloses a laser emitting device. The laser emitting device includes a housing in which a light-emitting component, a light-concentrating component and a light-scattering component are arranged. The light-scattering component and the light-emitting component are respectively fixedly connected to the housing. Moving relative to the housing, the light concentrating assembly includes a lens. The light emitted by the light-emitting component passes through the light-condensing component and the light-scattering component in sequence. The light emitted by the light-emitting component passes through the light-concentrating component and forms a cylindrical beam. After intersecting the work...
