    What should we do if the laser marking machine cannot produce light?
    Laser marker is to use laser beam to make permanent marks on the surface of different materials. The function of the mark is to expose the deep material through the evaporation of the surface material, thereby engraving exquisite patterns, trademarks and characters. Laser marking machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines and YAG laser marking machines.
    At present, laser marking machines are mainly used in certain occasions, with high precision and precision. Suitable for electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, glasses and watches, jewelry, auto parts, plastic buttons, building materials, PVC pipes, etc. But what if the laser marking machine does not work?
    Trouble phenomenon: Abnormal light output. When the ammeter is connected in series on the high voltage side, it can be seen that the ammeter shows abnormality, or there is current for a long time, sometimes there is no current, and sometimes it is out of control.
    Causes of failure: The main reasons are improper laser selection, failure of the main board, circuit board, power supply or control circuit connection, and failure of the cooling water circulation system.
    Method of exclusion:
    1. In the parameter setting, whether the laser type is correct is the main reason for the failure of continuous light emission.
    2. Pull out the control wire to see if it is loose. The connection is not reliable.
    3. Take out the control wire (nine-core wire) from the power supply, press the laser power point button, and analyze the power failure or motherboard failure.
    4. The normal point of shooting indicates that the power supply is not faulty.
    5. Irregular firing indicates that there is a problem with the power supply.
    6. When the power supply is normal, connect the control line and use a multimeter to measure the switch control pin on the terminal block. When the power is not turned on, the normal voltage is above 4V and below 3V, the motherboard output is abnormal; when the power is turned on, the pin voltage should be less than 2V, and when it is greater than 2.5V, the output is abnormal.
    7. Check whether the water circulation is normal, whether the water flow is normal sometimes, and whether there is a problem with the water protection device.

    The reason for the large price difference of laser marking machine
    When you buy laser marking equipment, such as laser marking machines, you will find that the current laser marking machine market is very chaotic, and even the price of the same type of laser marking machine is very different, leaving users no choice. The main reason for this situation is that there are many companies in the laser marking industry, which are different in terms of scale, quality and cost, and the quotations are naturally different.
    Before buying a laser marking machine, you should pay attention to the following aspects: the material, material, type and type of the product to be marked, and whether it needs to meet the production mode of the assembly line. First, through the analysis of these points, you can determine the appropriate marking machine. The reason for considering this factor is not only because it can better meet everyone’s marking needs, but also because laser marking machines can be divided into different models such as carbon dioxide, fiber laser marking machines, and semiconductor laser marking machines according to the marking method. , And their prices are also different. This is also an important factor affecting the price of laser marking machines.
    Factors affecting the price of laser marking machines Ⅱ. Due to the differences in domestic and foreign markets, in the production process of laser marking machines, their production processes and technical levels are different, which also leads to price gaps between different manufacturers. In general, the price of better equipment for imported laser marking machines is more than 100,000, and the price of cheap CO2 laser marking machines is more than 100,000 GE, which is more than 34,000 yuan. The home machine is obviously much cheaper.
    Whether it is a fiber laser marking machine, a fiber laser marking machine or a CO2 laser marking machine, the equipment launched by various companies can be used normally, and the configuration is the same, but there are differences in brands. Due to the difference of important lasers in the laser equipment, the price of the equipment is different. The laser uses rare element glass fiber as the gain medium, forming a high-power density particle conversion working medium in the special application of radio and television, and through other work The medium forms a so-called laser light source. This light source is widely used for marking/welding/cutting of metals and non-metals, and industrial manufacturers have great advantages.
    The benefits of high-quality laser accessories:
    A good laser accessory can bring many advantages to laser equipment. First of all, the manufacturing cost and technical support cost are low, and the cost is low; good fiber quality does not require strict position matching of crystal technology to the intake light source. It can be uniform and automatic The application of optical fiber also reduces the overall power consumption, thereby reducing the output energy. The output energy can be decomposed into more energy, and more coordination lines can be added to perform multi-beam coordination and concentrated work;    The environmental requirements are also lower, and the tolerance to dust and temperature can also be adapted to various environments; high-quality conversion rate, not only energy-saving and cost-saving, but also has a good effect.
    When we bought the equipment, although the same name, the same name, but the price is different. Therefore, when buying equipment, especially laser equipment, not only must listen to the reasons for the price, but also understand from multiple aspects.
