How to increase the service life of laser marking machine
In the current laser marking equipment, fiber laser marking machine marking speed is the fastest, its service life is also the longest of the same type of equipment, and fiber laser marking machine equipment failure rate With so many advantages of its own, it has been widely used in various industries. It is recognized as a new product that may completely replace the traditional marking processing method, and it is also one of the first choices in marking equipment. Among them, an important reason why it is loved by people is that fiber laser marking machine has a longer service life than other laser marking machines. Why does fiber laser marking machine have longer service life than semiconductor laser marking machine and other equipment? At present, the service life of semiconductor laser marking machine is 20,000 hours, while the service life of fiber laser marking machine is 100,000 hours. The price of semiconductor is much cheaper than that of optical fiber. Because of the low price, many manufacturers choose semiconductor laser marking machine. However, with the extension of the working time, the threshold current of the laser will slowly increase, which will lead to the degradation of the laser of the semiconductor laser marking machine. The laser needs to be replaced in about 2-4 years.
Why is there such a big gap between them?
1. The semiconductor laser used in the semiconductor laser marking machine has an extremely small die , The working current density and the optical power density are very high, and the semiconductor single crystal material as the laser material is more prone to defects. These defects gradually develop under the action of electricity and light, thereby causing the degradation of the device performance.
2. The mirror surface of the laser of the semiconductor laser marking machine is formed by a cleavage process. The mirror surface itself is affected by environmental conditions and pollution will also cause the performance of the laser to degrade. Die soldering is also a key technology. The die is soldered on the heat sink, and the active distance is only a few microns away from the heat sink; the semiconductor laser will generate heat when working, and if there is too much solder, it will slowly climb when heated, causing the semiconductor laser A short circuit occurs, causing the laser to degrade.
3. As the working time of the semiconductor laser marking machine increases, the threshold current of the laser will slowly increase , Resulting in degradation of the laser of the semiconductor laser marking machine.
The price of semiconductor laser marking machine is much cheaper than fiber laser marking machine. Because of the advantage of semiconductor price, many manufacturers choose semiconductor laser marking machine. However, as the working time increases, the threshold current of the laser will slowly increase, which will lead to the degradation of the laser of the semiconductor laser marking machine. In fact, with the increasing number of domestic Ru0026D and production fiber laser manufacturers and the more mature technology, the price of fiber laser marking machines has been declining, and it will not be long before semiconductor laser marking machines may be marked by fiber lasers. Machine replaced.
On the other hand, any laser marking machine equipment requires us to carefully maintain. In fact, the service life of a semiconductor laser marking machine is not fixed. As long as we pay attention to maintenance, we can still extend it. Service life. The same is true for fiber laser marking machines. As long as cleaning, cleaning, and maintenance work are carried out regularly, whether it is a semiconductor laser marking machine or a fiber laser marking machine, its service life can be basically extended appropriately.
In fact, as the number of domestic manufacturers of fiber lasers is increasing, the technology is becoming more and more Mature, the price of fiber laser marking machine has been declining, and the semiconductor laser marking machine may be replaced by optical fiber in a few years. Of course, any laser equipment needs our careful maintenance, whether it is a fiber laser marking machine or a semiconductor laser marking machine.
