The use of laser marking machine types of marking machines
The power-on sequence is:
1. Turn on the incoming power supply, turn on the key switch, and develop a high-power full-curing laser and a special laser for laser marking machines. Process principle and semiconductor laser marking machine At this time, the machine's ventilation and refrigeration system is energized, and the ammeter shows a value of about 7A.
2. Wait for 5 to 10 seconds, press the trigger button on the external control panel, the ammeter shows zero, after 3 to 5 seconds, the krypton lamp is lit, and the ammeter The display value is 7A, (refer to the laser power supply operation manual).
3. Turn on the power of the galvanometer.
4. Turn on the computer and call up the required marking file.
5. Adjust the laser power supply to the working current (10～18A), and then start marking. After marking, turn off the power of each component in reverse in the above order: 1. Adjust the working current of the laser power supply to the smallest (about 7A), ② turn off the computer, ③ turn off the power of the galvanometer, ④ press the laser marking motor stop button, ⑤ turn off the key switch, and ⑥ disconnect the incoming line power supply.
The above methods must be strictly installed when using them, otherwise the effect of use will be greatly reduced.
Electrochemical marking machine, which can be said to be the earliest product in production, is rarely used now, because the technical level was backward at that time, and the way people used it. Electrochemical marking machine It is only used for a period of time, and the electrochemical marking method is to use chemical reagents to react with the metal surface, thereby leaving traces on the surface of the workpiece.
Pneumatic marking machine, according to the needs of the industry, the improvement of technology and the development of the industry, the electrical marking machine is gradually replaced by the pneumatic marking machine. The source is used as the driving force, and the marking needle is used to form a concave mark composed of a dense lattice on the surface of the workpiece. The marking of the pneumatic marking machine is standardized, with high speed and large depth. The marking printed by the ultraviolet laser marking machine is beautiful, durable and can be Working in harsh environments, it is stable and reliable, which is why it will replace the electro-chemical marking machine in a short time.
Laser marking machine, the society is developing continuously, pneumatic marking machine can no longer meet the needs of production, so later produced laser marking machine, laser marking machine The speed of the marking machine and the aesthetics of the printed logo are much better than those of the first two products. The laser marking machine irradiates the surface of the product to be marked with a very high-density laser beam, so that the surface of the product melts or vaporizes instantly, so that the The required text or pattern logo is marked on the surface, because the laser marking machine has a wide range of use and good effect, and has now occupied the market.
When purchasing a laser marking machine, you should select a laser marking machine according to the classification of the laser marking machine and your own classification. The laser marking machine is divided into There are two types of IC automatic laser marking machines. One is YAG laser, which is mainly used for processing iron, copper, aluminum, gold, silver and other metals and various alloys, and the other is CO2 laser, which is mainly used for For the processing of wood, paper, acrylic, glass, and fabric, when purchasing, you can roughly choose which brand is based on the use of the two, and then choose according to the details, when purchasing To analyze according to the advantages of laser marking machine, 1. Laser marking machine, the biggest advantage is for optical contact, no mechanical pressure, high hardness, high brittleness, high melting point and high precision requirements, especially suitable for occasions , 2. During processing, the energy density is large, the time is short, the heat affected zone is small, the thermal deformation is small, the thermal stress is small, and the internal electrical performance will not be affected. 3. Direct burning and etching, it is a permanent mark and cannot be erased In addition, it will not fail, deform, fall off, and is suitable for anti-counterfeiting and anti-smuggling. This is a function that other products do not have.
