Laser marking machine mainly includes deep ultraviolet laser marking machine, green laser marking machine, semiconductor pump marking machine, lamp pumping ND: YAG laser marking machine, CO2 laser marking machine, fiber marking machine, rotating laser Marking machine:

    1. Deep ultraviolet laser marking:

    266 nm UV laser, high photoelectric conversion rate, long life of nonlinear crystal.

    Application: TFT, Wafer, IC and other products for various fine marking.

    Advantages: high precision, low power consumption

    Disadvantages: high price

    2, green laser marking:

    532nm green laser, high photoelectric conversion rate

    Applications: Stainless steel, copper alloy, glass, gemstone, ceramic, electroplated buttons, gold plated, optical lenses, ceramic perforated, high temperature PCB

    Advantages: high precision, wide use, low power consumption

    Disadvantages: high price

    3 semiconductor side pump YAG laser marking machine:

    Advantages: The price is relatively cheap (slightly higher than the lamp pump YAG laser marking machine}, easy to use, mature technology, wide application range, high power, no need to change the lamp frequently, the laser uses a long time.

    Disadvantages: The price is higher than that of the lamp pump YAG, and the spot size is large, which is not suitable for relatively fine processing.

    4 semiconductor end pump YAG laser marking machine:

    Advantages: easy to use, mature technology, wide application, long laser use time, high photoelectric conversion rate, small spot size, suitable for fine processing. Disadvantages: expensive, such as high cost of laser replacement

    5, lamp pump YAG laser marking:

    1064nm infrared laser

    Principle: YAG laser is a solid-state laser with a wavelength of 1.064um in the infrared light band. Xenon lamp is used as the energy source (excitation source), and ND:YAG is used as the medium for generating laser. The specific wavelength can promote the production level transition of the working substance to release the laser. The laser energy is amplified to form a laser beam for processing the material. The laser beam path is changed by a computer controlled galvanometer to realize automatic marking.

    Applications: metals, alloys and oxides, ABS, epoxy resin, ink, etc., widely used in electronics, jewelry, glasses, hardware, automotive, communications products, plastic buttons, IC and other industries.

    Advantages: wide use, low price

    Disadvantages: It is necessary to change the lamp once every three months. The spot is large and it is not suitable for fine processing.

    6, CO2 laser marking: (divided into glass tube CO2 laser marking machine and metal tube CO2 laser marking machine)

    10.64 um infrared laser

    Principle: The CO2 laser is a gas laser with a wavelength of 10.64um in the infrared light band. CO2 gas is used to charge the discharge tube as a medium for generating laser light. When a high voltage is applied to the electrode and a glow discharge is generated in the discharge tube, the gas molecule can be obtained. The laser is released, and the laser energy is amplified to form a laser beam for processing the material. The laser beam path is changed by computer to control the galvanometer to realize automatic marking.

    Application: It can engrave a variety of non-metallic materials, widely used in plastics, signs, packaging, handicrafts, leather, wood, textile, decorative and other industries for leather carving, wood carving, glass cutting, wood cutting.

    Advantages: It is used for non-metal marking and cutting, and the speed is faster. The price is cheaper than the YAG laser marking machine of the lamp pump, and the technology is mature.

    Disadvantages: low power, not suitable for fine processing, can not hit metal, has a certain slope when cutting.

    7, fiber marking machine:

    Advantages: more flexible and convenient, smaller size. Small spot size, suitable for fine processing. Air cooling, reducing the cost of consumables required for water cooling.

    Disadvantages: The optical fiber marking machine has a higher price and a lower power, and is not suitable for laser deep processing.

    8, rotating laser marking machine:

    Advantages: It can be rotated 360 degrees on the cylinder to solve the shortcomings of the above laser marking machine which can only be marked on the plane. It is widely used for marking of cylinders such as pens, gold pens, chopsticks, steel cups, bearings, etc. High power.

    Disadvantages: large power consumption, more expensive.

    4. Code and marking are a name for the method of processing on an object.
