People often use optical fiber laser marking machine for processing or production. I believe it will happen to everyone. After using it for a period of time, the fonts marked by optical fiber laser marking machine will be unclear. Many people have questions, why does the fiber laser marking machine mark the fonts unclearly? How should it be solved? Let's follow the editor to take a look at the reasons and solutions for the unclear marking font produced by the fiber laser marking machine.

1. The use time is too long. The use time of any fiber laser marking machine is limited. After a certain period of time, the laser module of the fiber laser marking machine reaches the end of its life, and the laser intensity will drop, resulting in unclear marking.

Solution:
One is to pay attention to the regular operation and daily maintenance of the fiber laser marking machine. You can find that the service life of some fiber laser marking machines will be shorter for the same manufacturer and model, and some will be longer. The main reason is that the user The second is that when the optical fiber laser marking machine reaches the end of its service life, the problem of operation and maintenance can be solved by replacing the laser module.

2. Operational issues. The main reason may be that the marking speed is too fast, the laser power current is not turned on or is too small.

Solution:
First of all, we must determine what causes the fiber laser marking machine to mark the text unclearly. If the marking speed is too fast, the marking speed can be reduced to increase the filling density. If the laser power supply current is wrong, the power can be turned on. The current is to turn on the power of the power supply current.


3. The problem of equipment. Such as field lens, galvanometer, laser output lens and other equipment problems. The field lens is too dirty, flowery or oily, which affects focusing, uneven heating of the vibrating lens, screaming or even cracking, or the film of the vibrating lens is contaminated and damaged, and the laser output lens is contaminated.

Solution:
When the optical fiber laser marking machine is produced, an exhaust fan should be added to prevent fouling. If it is the problem of fouling and fouling, the lens can be wiped. If it cannot be wiped, it can be sent to a professional manufacturer to solve it. Regarding the galvanometer For the problem of broken, it is recommended to replace the lens, and finally seal the galvanometer system to prevent the entry of moisture and dust.

Through the above introduction, everyone should know some reasons and solutions for the unclear marking of the optical fiber laser marking machine. In fact, there are many reasons that affect the unclear marking of the optical fiber laser marking machine. Everyone is not sure that it is best to send it. The manufacturer solves it.
