Application of Industrial Control Computer in Laser Marking Machine

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.

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.

The 4U high rack-mount chassis supports ATX industrial motherboards or 14-slot backplanes. The new front panel product design is easy to customize. Two easy-to-maintain SATA hard disk trays provide the best data mirroring backup, supporting two 5.25 inches and one 3.5 Inch disk, front USB and PS/2 interface, visible warning module to increase system ease of use, reduce system downtime, optional power supply: 300 watts/400 watts ATX or 300 watts/400 watts redundant power supply

·After 10,000-character mark production verification, high control accuracy requirements have been achieved and customer needs have been accurately fulfilled.

â—† High stability: Due to the use of a highly reliable HOLL original machine for processing, the stability of the system is enhanced;
â—† Flexible configuration: It adopts distributed structure and flexible configuration;
â—† High cost performance: HOLL IPC has better scalability, rational use of various methods to optimize the cost of the entire system.
