Anwendung der Hochleistungs-UV-Laserquellenmarkierung auf Kunststoff

Werden die beiden Scanning-Galvanometer im 90-Grad-Winkel zueinander montiert, kann eine UV-Laserbeschriftungsmaschine beide Seiten des Werkstücks beschriften. Die Übergangszeit des Laserstrahls, der sich von einem Scan-Galvo zum anderen bewegt, beträgt etwa 50 ms.

UV-Laserbeschriftungsgerät: Verfärbung

Die Markierung auf elektrischen Schaltern aus Kunststoff verändert im Allgemeinen die Farbe unter der Oberfläche des Materials, z. B. Karbonisierung. Bei Verwendung einer UV-Laserbeschriftungsmaschine kann eine schwarze Markierung durch selektives Karbonisieren des Kunststoffuntergrundes erreicht werden. Der Eintrag von Wärmeenergie ist auf einen kleinen gekennzeichneten Bereich beschränkt, so dass der Markierungsinhalt und das Hintergrundmaterial klar unterscheidbar und leicht zu identifizieren sind.

The wavelength of the UV laser marking machine is 355nm. It provides a new method for marking plastic electrical switches. In addition to the characteristics of general marking machines, the additional outstanding advantage of successful laser is: one laser head can be installed with two scanning galvanometers. So the marking speed can be doubled, or the part can be marked on both sides. The fastest marking speed can reach 3000 characters/sec.

The application of UV laser marking machine has attracted much attention because it has created a new way of marking plastic materials. The energy output by the short-wavelength ultraviolet laser stimulates the photochemical reaction of the material, and the ultraviolet laser marking machine avoids the excessive input of heat and causes the material to be damaged. The main features of UV laser marking machine: fast speed and high resolution. When processing some sensitive materials, such as plastics containing flame retardants, UV laser marking machines can achieve high-resolution marking with the best surface quality and fastest processing speed. Compared with infrared and green laser marking machines, UV laser marking machines do not require any expensive laser-sensitive additives during material processing, which can significantly achieve faster processing speeds and better marking quality.

Mark the same content at the same time

Success Laser's UV laser marking machine for plastic applications Dual scan head system with synchronised beam splitter, each scan head outputs 1/2 of the laser energy. The two scan heads simultaneously print the same content on the workpiece, doubling the throughput of the entire system.

Mark the same or different content in sequence

Dual scan head system with asynchronous beam splitter, different content can be marked separately in sequence. The energy of the laser is not split, and all the energy of the laser is introduced into the two scanning galvanometers in sequence by the shutter. The marked content can be the same or different.
