Laser marking machine for the modern open up more areas
First, laser marking machine is a new technology
In recent years, with the improvement of sustainability and practicability of the laser, with the rapid development of computer technology and improvement of the optics, promoted the development of laser marking technology.
Is laser marking machine and laser welding, laser cutting, laser drilling, laser heat treatment is applied to the development of new processing technology, through the use of high energy density of laser beam on the target function, make the physical or chemical changes in target surface, thus obtain visible mark way of design, namely high energy laser beam focus on material surface, make the material rapidly vaporized, form, along with laser in material surface regularly moving control of laser open at the same time, the laser beam is specified in the material surface processing into a pattern; Laser marking is a kind of non-contact, no pollution, no wear new tag technology.
On the principle of a laser target can be explained, the computer control of high energy density of focused laser beam according to the predetermined trajectory on mechanical parts, electronic components, instruments and meters, etc need to be marked surface of workpiece, the surface material to achieve instant vaporization or chemical change change color, carved with certain depth or color of the text, pattern, etc., so as to leave a permanent mark on the workpiece surface.
Second, the laser marking non-contact permanent identity
Laser marking is through the use of high energy density of laser beam on the target function, make the physical or chemical changes in target surface, thus obtain visible design way of marking, laser on the surface generated by mark strong permanent is its outstanding characteristic. Laser marking machine and (laser printer, laser printer, laser marking machine), is an important application of laser processing principle, the use of the treated laser beams in the material surface, light energy instantly converted into heat energy, the surface material instantly melted even gasification, forming a tag.
Laser marking technology in recent years, more and more applications in the field of printing, including laser marking can be applied to plastic and rubber, metal, silicon and other materials, laser marking machine easy to operation, as long as know basic computer knowledge, can operate the laser marking machine; In the tag in the printing industry, laser marked with the following features:
1. Permanent; Such as tag will not by environmental relations (touch, acid and alkaline gas, high temperature, low temperature, etc.) and fade.
2. The rubber seals; With laser marking technology, fashioned out of generic and not easy to change, to a certain extent, has a strong security.
3. Non-contact; Laser engraving laser scalpel "other than mechanical processing, can be in any regular or irregular surface printing tags, won't produce internal stress and marking after the workpiece, the original precision of workpiece. Do not produce corrosion on the surface of a work, no tool wear, non-toxic, non-polluting, is a kind of clean and pollution-free high environmental protection process technology.
4. Wide applicability; The use of lasers in processing means, to a variety of metals, non-metallic materials (aluminum, copper, iron, wood, etc.) processing.
5. High precision carving; Laser marking machine engraving items texture fine, minimum line width up to 0.04 mm. Mark clear, durable and beautiful. Laser printed label can meet the minimum needs of huge amounts of data can be printed on the plastic parts, have stronger market competitiveness.
Three, a laser target application
Laser marking technology is one of the biggest application fields of laser processing.Advantage significantly because of a laser target, laser marking can play all kinds of characters, symbols and motifs, characters can from mm to micron size, it has special significance to the products of security, has been widely applied in all walks of life, such as used in electronics, instrumentation, communications equipment, packaging, beverages, batteries, sanitary ware, electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware, tools, accessories, precision instruments clocks and watches, glasses, jewelry accessories, auto parts, machinery manufacturing, plastic buttons, plastic marking, cutting, assembly line clothing, fabric, marking on the tire surface, also suitable for ceramic color sticker marking, marking the glass surface, for high quality, high efficiency, no pollution and low cost of modern processing production opens up broad prospects.
