Nowadays, social production is becoming more and more intelligent, and the development of laser industry is changing with each passing day. Due to the laser beam characteristics of special, since birth, it plays an extremely important role in the field of mechanical, continuously go deep into the industrial production of various industries, and by its unique superiority, has become an important processing technology, manufacturing has been hailed as a new processing technology of the 21st century.
Flow continuously over time as laser application industry is innovation, innovation to accelerate the laser equipment, including Laser marking machine is a very important part of the laser technology, ultraviolet laser marking machine as one of the laser marking machine series product, is the latest research and development of a mature laser processing technology.
In the field of modern precision machining, because of the traditional laser marking machine USES a laser hot working technology, has restricted the development of precision, in this context, the ultraviolet laser marking machine has become the darling of the new era. It is a cold working process, the machining process is referred to as "light corrosion effect", "cold" (uv) with high load energy photons, able to break down the material or chemical bonds within the surrounding medium, to make the material in the thermal process of destruction, layer and near the area does not produce heating or thermal deformation, etc., finish the material with smooth edge and low limit of carbide, so the precision and the lowest heat affected it, laser technology is one of the great leap forward.
Laser marking machine can engrave metal and a variety of non - metal materials. It is more suitable to be used in some cases where more precise and higher precision are required. It is applied to electronic components, mobile phone communication, hardware products, tool accessories, precision instruments, glasses and clocks, jewelry accessories, automobile accessories, plastic keys, building materials, PVC pipe materials. However, due to the high cost, laser marking machines have been gradually replaced by starting marking machines for some metal or non-metal parts in recent years.
Laser marking is the use of laser beam on a variety of different materials on the surface of permanent marks. Effect of marking machine is through the evaporation of surface material to reveal deep material, either light energy caused by surface physical chemistry and "engraved" traces of a physical change or light energy to burn, by part of the material, show the etching, text.
At present, there are two universally recognized marking principles:
1. The "hot work" has higher (it is centralized energy flow), the laser beam irradiation in processed material surface, material surface absorption of laser energy, produce excitation in the area of the irradiation process, so that the material surface temperature rise (or coating), abnormal, melting, ablation, the phenomenon such as evaporation.
2. "cold-working" photons with high load energy (uv) can break chemical bonds in materials (especially organic materials) or surrounding media, causing non-thermal process destruction of materials. The cold has special significance in the laser marking processing, because he is not a thermal ablation, but do not produce side effects of the thermal damage, cold strip break chemical bonds, and thus of the processed surface layer and the nearby area does not produce heating or thermal deformation, and so on. For example, in the electronics industry, chemical value films are deposited in the substrate material and narrow grooves are made in the semiconductor substrate.
Currently on the market the most common laser protein tsundere mainly by CO2 laser marking machine, YAG laser marking machine, YAG later gradually replaced by semiconductor laser marking machine, laser marking machine market share most of an aircraft, and high-end some of optical fiber laser marking machine, uv laser marking machine, etc.
Laser marking machines can be divided into:
CO2 laser marking machine, semiconductor laser marking machine, YAG laser marking machine, optical fiber laser marking machine.
According to different laser visibility, it can be divided into:
Ultraviolet laser marking machine, green laser marking machine, infrared laser marking machine)
According to different laser wavelengths, it can be divided into:
Deep ultraviolet (below 200 nm) laser marking machine, uv laser marking machine (355 nm), green (532 nm) laser marking machine, lamp pumped YAG laser marking machine (1064 nm), semiconductor side pump YAG laser marking machine, semiconductor end pump YAG laser marking machine (1064 nm), optical fiber (1064 nm) laser marking machine, CO2 laser marking machine (10.64 um).
Application of laser marking machine:
Can carve a variety of non - metallic materials. Used in garment accessories, medical packaging, wine packaging, building ceramics, beverage packaging, fabric cutting, rubber products, shell nameplate, gift technology, electronic components, leather and other industries. Can engrave metal and a variety of non - metallic materials. It is more suitable to be used in some products with high precision and precision.
Applied in electronic components, integrated circuit (IC), electrical appliances, mobile communications, hardware, tools, accessories, precision instruments clocks and watches, glasses, jewelry accessories, auto parts, plastic buttons, building materials, PVC pipe, medical equipment and other industries. Applicable materials include: ordinary metals and alloys (iron, copper, aluminum, magnesium, zinc, etc) all metal, rare metal and alloy (gold, silver, titanium), metal oxide (either all kinds of metal oxide), special surface treatment (phosphating, anodized aluminum, plating surface), ABS material (electrical appliances shell, daily necessities), ink (pervious to light buttons, printing products), epoxy resin (encapsulation of electronic components, insulating layer).
