Classification of marking machines
1. Lamp pumped YAG laser marking machine
The lamp pump YAG laser marking machine adopts a stable and efficient concentrating cavity and a large multiple laser beam expanding system. The beam quality is better, the laser power is large, the peak power is high, the pulse width is small, and the energy is more concentrated. The current and software control are continuously adjustable, and the engraving depth is deep (<2.0mm); the industry application is more targeted.
Large laser power, good stability; stable laser mode, narrow pulse width, more concentrated laser energy; uniform and fine engraving line width (<150μm); strong engraving depth and high efficiency; complete optical path sealing, strong environmental adaptability; Beautiful appearance and reasonable mechanical structure.
YAG lamp pump laser marking machine is widely used in hardware, precision machinery, electronic components and other industries, especially suitable for mold processing, printing wheel engraving and all metal marking requirements requiring deep engraving. In the metal engraving application, the machine has the characteristics of deep depth, fast speed, stable operation and fine graphics. The metal materials can be iron, stainless steel, copper, aluminum and so on. Typical application cases, such as indexing and marking of circular and umbrella metal dials for various machine tools, laser marking of metal ruler scales, etc.
2. Semiconductor pumped YAG laser marking machine
The semiconductor pump laser marking machine uses a semiconductor laser diode (measuring surface or end face) with a wavelength of 0.808um to pump Nd:YAG medium, so that the medium generates a large number of inverted particles to form a giant pulse with a wavelength of 1.064um under the action of the Q switch. Laser output, high efficiency of electro-optical conversion. The semiconductor pump laser marking machine and the lamp pump YAG have better stability, power saving, no need to change lamps, and the like, and the price is relatively high.
Marking speed can be obviously improved under the same effect of marking, typical applications such as anti-white effect, anodizing layer on aluminum surface, laser coding of animal ear mark, laser marking of metal signage automatic loading and unloading. The laser output is stable, and a bright, repeatable pattern can be marked on the stainless steel plate. The new optical path sealing method ensures the safe operation of the pump head and has a long maintenance-free period.
Engravable metal and a variety of non-metallic materials. It is especially suitable for applications where fine marking and high precision are required. Used in electronic components, hardware products, tool accessories, integrated circuits (IC), electrical appliances, mobile communications, precision instruments, glasses and watches, jewelry, auto parts, plastic buttons, building materials, PVC pipes, medical equipment and other industries.
Common metals and alloys (all metals such as iron, copper, aluminum, magnesium, zinc), rare metals and alloys (gold, silver, titanium), metal oxides, special surface treatments (phosphorus, aluminum anodization, electroplated surfaces), ABS material (electrical appliance casing, daily necessities), ink (transparent button, printed product), epoxy resin (encapsulation and insulation of electronic components).
3 fiber laser marking machine
It is mainly composed of laser, vibrating lens and marking card. It uses laser fiber laser to produce laser marking machine. The beam quality is good, its output center is 1064nm, and the whole machine life is about 100,000 hours. Compared with other types of laser marking The device has a longer life span and an electro-optical conversion efficiency of 28% or more. It has a great advantage in conversion efficiency of 2%-10% compared with other types of laser marking machines, and has outstanding performance in energy saving and environmental protection.
Fiber lasers have a lifespan of about 100,000 hours, work 365 days a year for 24 hours a day, and have a lifespan of more than 12 years. They are truly maintenance-free.
The fiber marking machine is small in size (only the size of the ordinary computer mainframe), the electric power is <200W, the weight of the whole machine is <22KG (not including the computer and the non-standard electronic control unit), and the built-in air-cooled cooling method is adopted, which discards the cumbersome and easy problem. The water-cooled unit can even be powered by a 24V battery, which is truly energy efficient and portable.
The fiber spot marking machine has a very good spot pattern, and the single line is finer, which is suitable for ultra-fine processing. The 20W fiber basically covers the processing range of 50W semiconductor, and the system integration is high, the fault is small, and it is really suitable for industrial processing. Applications.
4.CO2 laser marking machine
The CO2 laser marking machine adopts high-speed scanning galvanometer, high-performance RF laser, ultra-high speed, accurate quasi-performance and stable operation for 24 hours. Suitable for marking of most non-metallic materials, such as paper packaging, leather fabrics, plexiglass, resin plastic materials, bamboo and wood products, coated metals, PCB boards, etc.
Widely used in the fields of medicine, personal care products, tobacco, food and beverage packaging, alcohol, dairy products, clothing accessories, leather, electronic components, chemical building materials and other fields of production and effective date, batch number, shift, manufacturer name and logo, etc. Graphic and text markup.
