The structure, characteristics and application of co2 laser marking machine

CO2 marking machine.

1. Hard glass: This part is made of GG17 material, used to make discharge tube, water cooling sleeve, gas storage sleeve and return air pipe, sealed carbon dioxide The laser marking machine is usually a three-layer casing structure. The inside of Z is the discharge tube, the middle is the water network casing, the outer layer of Z is the gas storage casing, and the return air pipe is used to connect the discharge tube and the gas storage tube.

2. Resonator: This part of the carbon dioxide marking machine consists of a full mirror and an output mirror. The general mirror of the resonator is usually based on optical glass, the surface is a gold film, and the gold mirror With a reflectivity of over 98% near 10.6um, the output mirror of the cavity 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.

3. Electrode: Carbon dioxide marking machine usually adopts cold cathode and has a cylindrical shape. The cathode material of laser marking machine has a great influence on the life of the laser. The requirements are: low sputtering rate and low gas absorption.

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 pipe, and the other end is connected with the discharge pipe through the spiral return pipe, so that The gas can be circulated in the discharge tube, the gas is circulated in the gas storage tube, and the gas in the discharge tube can be replaced at any time, the carbon dioxide marking machine is widely used for non-metal marking and engraving of acrylic and plastic products, it has been developed Ability to mark mild steel.

(1) Most metal or non-metallic materials can be processed, 2, (2) The laser adopts non-mechanical 'knife' processing, the material has no mechanical extrusion or mechanical stress, No 'knife' wear, no toxicity, little environmental pollution.

(3) The laser beam is very thin, so the material consumption of the laser marking machine to process the UV laser marking machine is very small, 4, (4) During the processing , X-rays are not attacked like processing methods such as electron beam bombardment, and are not disturbed by electric and magnetic fields. 5, (5) The operation is simple, and CNC numerical control technology is used to complete automatic processing, which can be used for high-speed and high-efficiency processing of parts on the production line, Available as part of a 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 a camera system, it can investigate or monitor the condition of the machined surface, laser marking machine 5, (8) It can pass its light-transmitting material (such as quartz and glass) processing, 9, (9) laser marking machines can use prism and mirror systems (for Nd:YAG lasers, also fiber optic light guide systems) to collect beams onto inner and outer surfaces, workpieces or skewed outer surfaces. Surface is processed.

(10) Symbols such as barcodes, numbers, characters, pictures, etc. 11, (11) The line width of these marks can be as small as 12Mm, and the line depth can be less than 10Mm, so it can symbolize Zero appearance for 'mm-level' scale.

For general metal material symbols, due to the ablation of lines of several microns or deeper from the surface (the width can be several microns to tens of microns), the laser marking machine is therefore the color of the line. And reflectivity differs from the original form of the human eye. Depending on the contrast, one can be sensitive to these lines (and the shape, number, pictures, logos, etc.) of the lines.

With regard to glass, these lines ablate with a 'smooth' effect, with regard to plastic, there is visual contrast and haze due to photochemical reactions and ablation, if the surface of the material is coated There is a special colored substance for symbol processing, then the colored substance will be fixed (high temperature ablation of the material) and it will be colored on the line.

However, with the increased prevalence of cij printer, it has become far more affordable.
