Laser marking is the use of laser beams to mark permanent surfaces on a wide variety of surfaces. The effect of marking is a deep substance through the surface material evaporation, or by light can cause chemical and physical changes of the surface material "carved out" marks, or burned part of the material through the light, show the desired etching patterns ，characters and beautiful words,logo.
It is mainly divided into CO2 laser marking machine, Semiconductor laser marking machine, fiber laser marking machine, YAG laser marking machine,
Laser marking machine is mainly used at present some required more precise and higher. Used in electronic components, integrated circuit (IC), electrical appliances, mobile phone communications, hardware, tool accessories, precision instruments, watches, jewelry accessories, auto parts, plastic buttons, building materials, PVC pipe.
#Laser power supply:
The laser power supply for fiber laser marking machine is a power supply for fiber laser, whose input voltage is AC220V alternating current. It is installed in the marking machine control box.
An optical fiber laser marking machine adopts an imported pulsed fiber laser. Its output laser mode is good and the service life is long. It is designed and installed in the shell of the marker.
#Galvanometer scanning system
Galvanometer scanning system consists of two parts: optical scanner and servo control. The whole system is designed and manufactured with new technology, new material, new technology and new working principle.
The optical scanner adopts a servo motor operated by magnetic deflection. The utility model has the advantages of large scanning angle, big peak torque, large load inertia, small electromechanical time constant, fast working speed, stable and reliable, etc.. Precise bearing clearance elimination mechanism provides the lowest axial and radial runout error; "electronic torsion bar" to replace the traditional elastic torsion bar, greatly improving the reliability and service life and long-term work; any position of zero power principle can reduce power consumption, and reduce the heating effect of the device, save the thermostat provide performance; high linearity, high resolution, high repeatability, low drift, high stability and precision position detection of advanced sensor technology.
The optical scanner is divided into X direction scanning system and Y direction scanning system, each servo motor shaft is fixed with a laser reflecting lens. Each servo motor is sent out by computer respectively.
The focus of the focusing system is to focus the parallel laser beam at one point. Mainly uses the f- lens, f- lens with different focal length, marking effect and scope are not the same, the fiber laser marking machine imported high performance focusing system, the focal length of the lens f=160mm in its standard configuration, the effective scanning range is 110mm. The user may select the type lens according to the need.
Optional F- theta lenses are available:
F=100mm, the effective focus range is 65mm.
F=160mm, the effective focus range is 110mm.
computer control system
Computer control system is the center of the control and command of the laser marking machine, and also the carrier of software installation. Through the coordinated control of the acoustooptic modulation system and galvanometer scanning system, the workpiece marking process is completed.
The computer control system of optical fiber laser marking machine mainly includes the case, main board, CPU, hard disk, memory, D/A card, floppy drive, monitor, keyboard, mouse and so on.
