Fiber laser marking machine is a high and other types of laser marking machine equipment, his considerable merits and prospects to detailed comparisons Today we look. Laser marking machine divided according to different lasers YAG laser marking machine, CO2 laser marking machine, semiconductors, the main difference lies in the different lasers, and the difference between different laser wavelength lasers in many laser marking machine Fiber laser marking machine to the most expensive. The naturally has his expensive truth. Let us look at the fiber laser marking machine laser marking machine relative to other What are the advantages. Fiber laser marking machine is actually advantage lies in the advantages of fiber lasers. Advantages of fiber lasers used in laser marking A. The beam quality is good, close to the diffraction limit. TEM00 fundamental transverse mode output, M2 close to 1, the beam divergence angle of 0.24mrad; B. high pulse repetition frequency, output power stability, single pulse energy fluctuations of less than 1%, thus enabling high-speed laser marking, can be precisely controlled spot size, depth, shape; C. High efficiency, plug efficiency up to 20%, electro-optical conversion efficiency of up to 70%; Strong D. environmental adaptability, in high vibration, high humidity environment of continuous work properly. E. No water cooling device, small size, high efficiency, high reliability, long maintenance-free, saving the cost. The light source is a laser diode optical drive power. Fiber laser controller for controlling the fiber laser working condition, while marking machine controlled by a microcomputer that controls the laser output. Galvanometer system is an important component of fiber laser marking system, laser galvanometer through movement, out of a particular trajectory in part on the need to hit the target. fq lens through which the laser beam is focused onto the workpiece surface. In galvanometer system workflow. There are two internal systems were galvanometer servo motor driven by a high-precision mirrors. Servo motor rotates in the microcomputer-controlled angle of the two mirrors, the laser beam reflected by these two reflecting mirrors, the focusing lens to the fq different locations on the workpiece. On the PC via a dedicated input control software requires marking marking text and drawings, set the size of text and drawings, the total marking area, walking speed of the laser beam and the need to repeat the number, the computer will be able galvanometer under the control of movement, control of the laser beam on the workpiece standard carve set text and drawings. Computer software can identify special marking collected by a digital camera or scanner input, any complex plane image graphics and text as well as two-dimensional bar code on the Internet to download code and computer production, produce a variety of markers, it is converted into a digital signal, programmed to calculate the control signal is then converted into a current input drives the formation of the corresponding control signal through D / A card control precision servo motor operation, which control the direction of the x and y directions reflection. Galvanometer deflection angle of the laser beam focus spot according to the set of patterns, text trajectory, the surface is etched to form a permanent notch. Scribed line width can reach 20 microns, and the software has automatic image distortion correction function to achieve precise image marking.
