A laser projector that changes the spatial direction sub-tuning of the focused laser spot

Abstract

The invention provides a laser projector for changing laser focusing light spot space direction adjustment. The laser projector comprises side buckles, a laser light spot adjustment device, a laser sleeve, heat dissipating grooves and a tail connecting guide piece; two side buckles are provided and arranged on the left and right sides of the laser sleeve; the laser light spot adjustment device ismounted in the laser sleeve in an embedding mode; and two heat dissipating grooves are provided and arranged on the upper and lower end surfaces of the laser sleeve. During laser carving, a guide control mechanism can be used for controlling a falling point centralized control mechanism; a light spot after-adjustment mechanism can be gradually overlapped with the axis of a ring in the center of amain fixed through falling mechanism; under control by a ring through piece, emitted laser beams can be identified through the guide control mechanism for strength adjustment; and the light beams canbe adjusted through laser stop materials, so that the laser carving can enter micro carving, and the upper and lower surfaces are maintained complete under control of falling point light spots.

Description

technical field [0001] The invention belongs to the field of laser materials, and more specifically relates to a laser projector for changing the spatial direction distribution of laser focus spots. Background technique [0002] Laser engraving has gradually entered the market. Laser engraving mainly uses the emitted laser on the transparent carved stone, and directly performs image engraving on the inside through the outside. It can adjust the angle and intensity of the laser to achieve coloring and depth. Control, and then complete the engraving work. [0003] Based on the above description, the inventors found that an existing laser projector that changes the spatial direction of the laser focus spot mainly has the following deficiencies, such as: [0004] When performing laser engraving, the intensity of the focused material sheet is often used to control the beaming intensity of the emitted laser light, but it is difficult to control the focused spot of the laser, so t...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a laser projector that can change the spatial direction of the focused laser spot, so as to solve the problem that the emitted laser light usually needs to be adjusted by focusing on the intensity of the focused material sheet during laser engraving. Control, but it is difficult to control the focus spot of the laser, so that although the laser engraving can generally be engraved internally and present four-sided imaging, the upper and lower sides are easy to be difficult to control due to the landing point. There will be problems with redundant nicks
