Deciding whether the development of an industry’s technology is mature depends on the degree of progress of that era. Nowadays, science and technology are becoming more advanced, and laser technology is also becoming more advanced. People have developed a laser printer, which is also a marking tool. Its main principle is the inkjet method to achieve marking. However, this method and people’s higher and higher requirements for life have gradually been eliminated.
So because of the high demand, there will naturally be many manufacturers who are ignorant of the conscience of making and selling fakes. In order to enable consumers to better and more safely enjoy their rights, they have played a huge role, and their anti-counterfeiting functions have been smoked. Manufacturers of wine shops buy in large quantities, it can have a separate code on each bottle of wine, each wine lid or each cigarette box, and its code mark is permanent, clear and unchangeable.
Many manufacturers have purchased laser marking machines and use the equipment 24 hours a day. Without maintenance of the equipment, it is very easy to malfunction.
When purchasing, you must pay attention to the details of the structure. Its resolution determines the comprehensive application effect and quality of the laser marking machine. The price of the marking machine differs depending on the laser beam. The symbols produced by a good marking machine are regular, standard and beautiful.
The principle of the laser marking machine is mainly a tool that uses a laser beam to carve marks on the surface of a substance. The reason why laser marking machines are widely used is because they are the most accurate and environmentally friendly of all types of marking machines. Because the power is very high, it is also the most energy-saving, which can save the replacement cost of the company’s production line.
Fiber laser marking machine uses laser fiber as the medium, which has the advantages of good heat dissipation, high power, and high speed, which are favored by many industries. Fiber laser marking machine uses air-cooled laser diode as the pump source, which can be pulsed and connected, and it is more convenient to use. Speaking of this, do you know how many parts are required for a fiber laser marking machine?
- Laser
This is the core part of the laser marking machine. Depending on the size, it usually has many series of lasers: fiber, ultraviolet, CO2, YAG, semiconductor, etc. Its output laser mode is easy to replace and is designed to be installed in the casing of the marking machine. For example, IPG fiber lasers, Raycus fiber lasers, Chuangxin fiber lasers, co-product fiber lasers, JPT fiber lasers, excitation fiber lasers, etc.
- Laser power supply
The laser power supply of the laser marking machine is a device that provides power for the laser, and its input voltage is AC220V. Installed in the marking machine control box. It is a component that supplies power to the fiber laser. It is generally better to use MEAN WELL or HENGFU
3.galvanometer field lens scanning system
Galvo scanning system
The galvanometer of the optical fiber marking machine is generally a digital galvanometer with a 10mm spot. Of course, there are some people who use an analog galvanometer. Generally, these people are early customers who sell Scanlab’s 10-spot analog galvanometer. Most of the galvanometers used in fiber marking machines are digital galvanometers. The digital galvanometer is actually not much different from the analog galvanometer. It is an analog galvanometer plus a DA, so that the signal is transmitted in the form of a digital signal during the transmission process. Generally, optical fiber marking machines use USB marking cards. The mirror must be a USB USB marking card, and the analog galvanometer must be a USB analog marking card. There are a lot of fiber optic galvanometers. At present, the mainstream galvanometers mainly include: scanlab, raylase, GSI, CTI, etc. The ones made in China include: Century Sonny, Jinhaichuang, Hanzu, Gavotec, Hezoli, Qinlong , Leiken, GM, Century Tuotian, No. 1 in the list, Shengketai, Jianlong, etc. Many Chinese-made galvanometer manufacturers are making scanlab-like galvanometers. In fact, these galvanometers are just choosing some better motors and adding a shell like scanlab to become a high-fake scanlab. The specific quality depends on the parameters of speed, temperature drift, accuracy, and warranty.
The galvanometer is composed of three parts: the stator, the rotor and the detection sensor. The entire system is designed and manufactured using new technologies, new materials, new processes, and new working principles.
The optical scanner adopts a servo motor with a moving magnetic spindle working mode. The optical scanner is divided into an X-direction scanning system and a Y-direction scanning system. A laser reflecting mirror is fixed on each servo motor shaft. Each servo motor is controlled by a digital signal from the computer to control its scanning track.
Field lens scanning system
Also called flat field focusing lens, scanning lens, F-θ lens. It is mainly used to focus the light from the galvanometer on a plane. At the time of purchase, you should pay attention to the marking range, and determine it according to your own needs. Don’t blindly ask for it. The wavelength of the optical fiber marking machine and the semiconductor marking machine are both 1064nm, and the field lens is generally universal. But sometimes if you use the original imported Scanlab galvanometer, its field lens connection ring may not be M85 * 1, and the field lens is generally M85 * 1 thread. At this time, a field lens conversion is required. Connect the circle.
Beam combiner: Mainly used in systems that use laser diodes for calibration. The YAG beam combiner is designed to transmit a 1064nm laser beam when it is incident at 45 degrees, and align it with a 650nm laser beam that is visible to the naked eye at 90 degrees.
4.computer control system
The computer control system is the center of control and command of the entire laser marking machine, as well as the carrier of software installation. Through the coordinated control of the acousto-optic modulation system and the galvanometer scanning system, the marking of the workpiece is completed.
5.focus system
The f-θ lens is mainly used. The focal length of different f-θ lenses is different, and the marking effect and range are different. The fiber laser marking machine replaces the imported high-performance focusing system. The standard lens focal length f = 160mm, effective scanning The range is Φ110mm. The user can choose a lens according to the needs.
6. marking control software
The laser marking machine software is an application interface used to control marking parameters, control debugging, and operate all marking actions.
Also called laser control card, laser marking card. Common marking cards include golden orange, samlight, Century Sunny, Zhongweixing, Taiwan Xingcheng 502B marking card, etc. They are used to draw pictures in the computer for optical fiber marking machines. Orange USB marking card, USB marking card is divided into USB analog marking card and USB digital USB interface, and the USB interface is connected to the USB interface. And the USB USB interface on the market now has two kinds of genuine and imitation. On performance, genuine and imitation. Almost; in terms of quality assurance, most imitations and originals are guaranteed for one year, and some imitations are guaranteed for two years. For example, in terms of price, the original and imitation versions are incomparable. However, the imitation version also has several characteristics. Many imitation versions have low software versions, only up to 2.5.3, and some imitation versions can reach 2.7.6.
7.pull the name
If a marking machine is regarded as a computer, the cabinet is equivalent to the shell of a computer. There are desktop computer shells and notebook computer shells. Then the marking machine has desktop marking machine cabinet, portable marking machine cabinet, and handheld Laser marking machine cabinet, various styles.
- Red light indicator:
It is also called a red light pen, used to indicate the light path, because the 1064nm laser is invisible, while the 650nm light of the red indicator is visible. The 650nm light is superimposed with the 1064nm light through the beam combiner, so the 650nm light Where it is pointed, the light of 1064nm is where it is, thus achieving the function of indicating the light path. The red light pen is installed in the red light beam combining frame.
Marking card power supply: as the name implies, it supplies power to the laser marking card.
Power supply filter: The power supply filter can compress the anti-interference effect and reduce the failure of the marking machine, such as crashes, random hits, intermittent filling, and missing filling.
