Embodiment Construction

[0024] Specific embodiments of the present invention such as Figure 1-8 Shown is the optical fiber laser engraving process for plexiglass, which includes the following steps: (1) designing the pattern style to be engraved, (2) placing the plexiglass workpiece to be engraved on the workbench, and the plexiglass workpiece The area to be engraved is suspended on the workbench, and the engraved part of the workpiece should not be in contact with the workbench, but should be suspended in the air, so that the heat dissipation will be sufficient, and the contact between the workpiece and the workbench will not be blackened. (3) Adjust the focal length and process parameters of the fiber laser machine. The focus is on the surface or inside of the plexiglass workpiece to be engraved. In this embodiment, its focal length is 193mm, and its process parameters include a power range of 3-20W. Laser or pulsed laser, the peak power of the pulsed laser does not exceed 20W, the speed is 350mm / ...

Abstract

The invention discloses a fiber laser engraving technological method for organic glass. The method comprises the following steps that an engraving pattern form is designed, an organic glass workpiece is placed on a workbench, the focal length and technological parameters of a fiber laser machine are adjusted, a needed pattern is engraved through lasers, nicks are formed on the surface of the workpiece, the front face and back face of an engraved sample are washed through hydrogen peroxide, and engraved words and pattern are brighter. The invention further discloses fiber laser engraving equipment for the organic glass. The fiber laser engraving equipment comprises the workbench with an open cavity, locating baffles capable of moving axially are arranged on the front end face and the rear end face of the open cavity, a to-be-engraved area is formed in space between the two locating baffles, and the to-be-engraved area can be adjusted according to the size of the organic glass workpiece. The engraved pattern is lasting, resistant to wear and clear, no contact mark exists in the processing process, operation is sanitary and clean, processing efficiency is high, the equipment is suitable for small-batch processing, production lines are easily integrated, and processing can be carried out in areas where the workpiece is hard to be in contact.

Description

technical field [0001] The invention belongs to the technical field of laser engraving, in particular to an optical fiber laser engraving equipment for plexiglass and a process method thereof. Background technique [0002] The working principle of laser engraving is to irradiate the surface of the material with a high-energy laser beam, a small part of the laser light is reflected, most of the light passes through the surface of the material, and is converted into heat energy in the material to heat the material. Due to the thermal effect of the material, the material is fully Laser beam irradiation with high power density to achieve melting and vaporization of the material surface [1] The temperature can vaporize or melt the material, and engrave the required graphics and characters as permanent marks. Fiber laser marking machines are mostly used in metal materials such as aluminum, iron, copper, etc., because the absorption rate of metal materials with a wavelength of 106...
