Take you to know several common Laser marking machines
Laser marking machine is widely used in our daily life. Laser marking machine is also called radium engraving machine, Laser marking machine, laser inkjet printer, laser engraving machine and so on. Different regions and industries have different names. Because the materials of processed products are different, the Laser marking machines used are also different, For different industries, different materials will have different Laser marking machine equipment, it is not difficult to choose a suitable Laser marking machine for their own products, because there are many types of Laser marking machine, so we must first understand the characteristics and application fields of various types of Laser marking machine, in order to choose the most suitable Laser marking machine. According to the division of light sources, the common Laser marking machines in our life include ultraviolet Laser marking machine, optical fiber Laser marking machine and CO2 Laser marking machine. Its principle is to use high energy density laser to irradiate the workpiece locally to vaporize or change the color of the surface material, so as to leave a lasting, clear and indelible mark. With the development of technology, desktop Laser marking machine, hand-held Laser marking machine and portable Laser marking machine with smaller volume and easy to carry are developed according to the application demand and in order to improve the production efficiency; Online Laser marking machine which can be integrated in production line; 3D dynamic 、Laser marking machine for surface marking; PCB Laser marking machine designed for PCB circuit board marking, CCD vision positioning Laser marking machine developed for batch irregular marking due to the difficulties of fixture design and manufacturing, such as difficult feeding, poor positioning and slow speed, has emerged as the times require. Ultraviolet Laser marking machine
The ultraviolet laser machine is developed by 355nm ultraviolet laser. It uses third-order intracavity frequency doubling technology to break the bonding between atoms or molecules by laser energy, making them become small molecules to vaporize and evaporate. Compared with infrared laser, ultraviolet laser is a real cold laser, and its thermal effect is very small. It can reduce the mechanical deformation of materials to a great extent, and the processing thermal effect is small. Therefore, it is mainly used for ultra-fine marking and carving, especially for food and medicine packaging materials High speed division of glass materials and complex pattern cutting of silicon wafer. UV marking machine is the preferred product for customers with higher demand for marking. It has the characteristics of high electro-optic conversion rate, stable operation of the whole machine, high marking accuracy, high work efficiency, modular planning and convenient device protection. It is mainly used for marking on the surface of packaging bottles of iPhone, cosmetics, drugs, food and other polymer materials; Marking and scribing of flexible PCB board; Silicon wafer micro hole, blind hole processing; LCD glass, glassware surface, metal surface coating, plastic keys, electronic components, gifts, communication equipment, building materials, etc. Fiber Laser marking machine
Fiber Laser marking machine is widely used at present. It uses fiber laser to output laser, and then uses high-speed scanning galvanometer system to realize marking function. The fiber Laser marking machine has high electro-optic conversion efficiency, adopts air cooling mode to cool, the whole machine has small volume, good output beam quality, high reliability, long life, energy saving and environmental protection, It can carve metal materials and some non-metal materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "carve" the trace through the chemical and physical changes of the surface material caused by the light energy, or to burn off part of the material through the light energy, and to show the required etched patterns, words, bar codes and other graphics. It is mainly used in the fields with high depth, smoothness and fineness. It is widely used in the marking of graphics and characters in many fields, such as integrated circuit chips, computer accessories, industrial bearings, clocks and watches, electronic and communication products, aerospace devices, various auto parts, household appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco and military affairs, And mass production line operation, and the marking speed is 3 ~ 12 times of the traditional first generation lamp pump marking machine and the second generation semiconductor marking machine.
CO2 Laser marking machine
CO2 Laser marking machine, commonly known as CO2 marking machine, the key core component is the type of laser, which is divided into glass RF tube and metal RF tube. From the market application point of view, the metal RF tube has high cost performance, the service life can reach more than 100000 hours, and the laser wavelength is 10.64 μ m. It belongs to mid infrared band, with high power and high electro-optic conversion rate, and uses CO2 gas as working material. CO2 Laser marking machine is a kind of high-performance laser equipment, which uses laser beam expanding, galvanometer, focusing, and finally controlling the deflection of galvanometer to realize marking. It has high marking speed and is suitable for marking most non-metallic materials. The effect of marking is to expose the deep material through the evaporation of the surface material, so as to carve beautiful patterns, trademarks, dates, logos or words. At present, CO2 Laser marking machine is mainly used in some occasions that require more precision. It is used in food, medicine, wine, electronic components, integrated circuit (IC), electrical appliances, mobile communication, building materials, PVC pipe and other industries.
