Causes of unstable marking of laser marking machine

  . The most likely cause is that the laser power (referring to how much work an object does in a unit time) is unstable (wěn dìng), but the laser power (referring to the object doing There are many reasons for instability (wěn dìng), and I will do it for us one by one.

Laser coding machine mainly engraves the trajectory of the character to be marked, while the dot-matrix laser machine engraves some important trajectory points of the character to be marked.

Therefore, under the same energy situation, the new dot matrix laser coding machine prints faster.

When the marking speed is set too fast, it is very easy to show that the marking is unstable (wěn dìng), but if it is because of this, it will be handled very well (chǔ lǐ), just slow down the speed Just fine; there is a problem with the optical path system of the laser (Emerson), you need to adjust it so that the beam expander is in an accurate position; the focal length is not accurate, you need to adjust the accurate focal length; the laser direction is not in the normal base, so let the lens enter the galvanometer The laser is in the position of the main base; the lenses and lenses show signs of dirt and wear (a basic type of component failure), etc., which need to be replaced or cleaned; the service life of the laser is reached and needs to be replaced.

  The laser spot pattern has changed, and the beginning is getting worse. In this situation, it is necessary to replace the marking card or the laser signal line and the laser power supply line. The specific situation depends on reality. The situation depends.

  The cooling capacity is unstable (wěn dìng), this situation may be that the ambient temperature is too high or too low, and the laser marking machine needs to be cooled or kept warm externally.

Laser coding equipment can be divided into two types: scribing type and dot matrix type according to the different marking forms.

At present, most of the laser coding equipment appearing in the market are of scribing type, while the new type of laser coding equipment adopts a new type of dot matrix technology-dot matrix retention technology.

Laser coding machine mainly engraves the trajectory of the character to be marked, while the dot-matrix laser machine engraves some important trajectory points of the character to be marked.

Therefore, under the same energy situation, the new dot matrix laser coding machine prints faster.

   The marking control card of the laser marking machine has a problem (Emerson). In most cases, the marking card can only be replaced.

The coding machine breaks through the standardization and singularity of traditional inkjet coding technology, creating a brand-new coding method, highlighting product characteristics and brand differences, and improving products in the increasingly fierce market China’s competitive ability, and at the same time provide a powerful tool for shortening the product upgrade cycle and flexible production.

The laser marking machine uses a laser beam to make permanent marks on the surface of various materials.

Laser marking machines can be divided into CO2 laser marking machines, semiconductor laser marking machines, YAG laser marking machines, and fiber laser marking machines according to different lasers.

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.
