System Overview
Because of the increasing demand for material processing, laser marking, a new technology developed after laser welding, laser heat treatment, laser cutting, and laser drilling, has become an indispensable processing tool. Laser marking technology has become the most widely used and most mature technology in the field of laser processing with its new contactless, non-polluting and non-abrasive marking process. The core of
Laser Marking Equipment is the laser marking control system. Therefore, the development of laser marking is the development process of the marking control system. In just 7 years, the control system has experienced the large-format era, the rotating mirror era and the galvanometer era in the field of laser marking, and the control mode has also experienced from software direct control to the control of the upper and lower machines to the real-time processing. A series of evolutions that are time-multiplexed.

System principle
The laser marking system is mainly composed of HOLL industrial computer, laser, galvanometric scanning system and f-θ lens. The power system is connected to 220V (50Hz) power supply for IPC and (gas/solid) laser respectively. The IPC passes laser marking. Engraving software controls galvo scanning system and laser power supply. When preparing for marking work, the IPC sends a signal to the power system to control the laser switch light and its laser power level. At the same time, a certain transformation is made according to the marking coordinate data and transmitted to the galvanic mirror scanning system. The galvo mirror scanning system receives The signal adjusts the X/Y-axis oscillating mirror, that is, the X/Y-axis oscillating mirror is deflected by a certain angle. At this point, the complete optical transmission path is that the beam emitted by the laser is refracted by the X and Y galvanometers, and then is incident on the surface of the workpiece to be marked.
