Laser Marking Machine Control System

With the continuous development and innovation of laser processing technology andcomputer control technology, laser marking technology is gradually replacing the traditionallabeling methods, laser processing with a non-contact, does not cause any pollution to theenvironment, no wear on the processing of materials and other unique features in the military,communications, industrial processing, health care, education and other aspects of aviationhas made a very wide range of applications and promotion.This topic standard machine control system is the basis of the functional requirementsfor the galvanometer laser research, control systems use a combination of the control boardand the expansion card control mode, using ARM+FPGA based motion control system forcontrol design, the main content of this research in the following areas:(1) Introduced the laser marking technology development status and its applications,laser marking machine control system’s basic working principle and workflow, and proposedcontrol system to meet the performance and functional requirements.(2) Laser marking machine control system design, including: the overall architecture ofthe hardware circuit design of the control system and the control system design.(3) Laser marking machine control system software design, first of all, on the Qmodulation frequency and laser power, marking speed were analyzed, and detailed analysis ofthe set delay time interpolation algorithm and vector marking two ways to improve thecontrol accuracy of the system. Finally, edit the marking content processing done in detail.(4) In order to solve human-computer interaction, the choice of the Qt applicationprogramming interface, the operating system selected Linux, the main menu of the controlsystem design and system parameters interface design, can effectively improve the lasermarking machine control system can be operability.(5) Through some simple test marking, laser marking machine control system basicallyarrive marking requirements.
