The structure, characteristics and application of laser marking machine


Author: Correct Pack -Laser Marking Machine Manufacturer

CO2 marking machine. 1. Hard glass: This part is made of GG17 material, which is used to make discharge tubes, water cooling sleeves, gas storage sleeves and return air pipes. The sealed carbon dioxide laser marking machine is usually a three-layer sleeve structure, the innermost It is a discharge tube, the middle is a water network sleeve, the outermost layer is a gas storage sleeve, and the return air pipe is used to connect the discharge tube and the gas storage tube. CO2 marking machine.

2. Resonant cavity: This part of the carbon dioxide marking machine is composed of a full mirror and an output mirror. The total mirror of the resonant cavity is usually based on optical glass, and the surface is a gold film. The reflectivity of the gold mirror near 10.6um exceeds 98%. The output mirror is usually made of an infrared material capable of transmitting 10.6um radiation, and Ge (Ge) is the substrate on which a multilayer dielectric film is formed. CO2 marking machine. 3. Electrodes: Carbon dioxide marking machines usually use a cold cathode and have a cylindrical shape. The cathode material of a laser marking machine has a great influence on the life of the laser. The basic requirements of the cathode material are: low sputtering rate and low gas absorption rate.

CO2 marking machine. Both ends of the discharge pipe are connected to the gas storage pipe, that is, one end of the gas storage pipe has a small hole communicating with the discharge tube, and the other end is connected with the discharge pipe through a spiral return pipe, so that the gas can circulate in the discharge tube, and the gas circulates in the gas storage pipe , and the gas in the discharge tube can be replaced at any time, the carbon dioxide marking machine is widely used in non-metallic marking and engraving of acrylic and plastic products, and it has developed the ability to mark mild steel. (1) It can process most metal or non-metal materials, 2, (2) The laser adopts non-mechanical“knife”processing, material without mechanical extrusion or mechanical stress, without“knife”Wear and tear, non-toxic, less environmental pollution.

(3) The laser beam is very thin, so the consumption of materials to be processed by the laser marking machine is very small, 4, (4) During the processing, X-rays are not attacked like electron beam bombardment and other processing methods , not interfered by electric and magnetic fields, 5, (5) Simple operation, using CNC numerical control technology to complete automatic processing, can be used for high-speed and efficient processing of parts on the production line, and can be used as a part of the flexible processing system. (6) The precision machining of the laser marking machine can be carried out using a precision workbench. (7) Using a microscope system or camera system, it can investigate or monitor the condition of the processed surface, laser marking machine 5, (8) It can process through its light-transmitting materials (such as quartz and glass), 9, (9) Laser The marking machine can use a prism and mirror system (for Nd:YAG lasers, a fiber optic light guide system can also be used) to collect the beam onto the inner and outer surfaces, the workpiece or the skewed outer surface for processing.

IC automatic laser marking machine. (10) Bar codes, numbers, characters, pictures and other symbols 11, (11) The line width of these marks can be as small as 12Mm, and the line depth can be less than 10Mm, so they can symbolize“mm class”The zero appearance of the scale. General metal material symbols, due to the ablation of lines a few microns or deeper from the surface (the width can be several microns to tens of microns), the color and reflectivity of the lines are different from those of the original human eye. One can be sensitive to these lines (and their shape, number, pictures, logos, etc.).

Regarding glass, the ablation of these lines by the laser marking machine has“smooth”Effect, regarding plastic, due to photochemical reaction and ablation, there is visual contrast and cloudiness, if the surface of the material is coated with a special colored substance for symbol processing, the colored substance will be fixed (high temperature ablation of the material) and it will be on the line coloring.
