Internal laser marking machine galvanometer system consists of two separately by the high-precision servo motor-driven mirror. The servo motor rotates under the control of the microcomputer, respectively two angle of the mirror, the laser beam reflected by these two mirrors is focused by lens f-q to a different location on the workpiece. On the computer control software, enter the desired text and marking pattern by special marking, set the text size and pattern, the total area of the laser beam marking speed of travel and the need for the number of repetitions, the computer will be able to galvanometer under the control of movement, control of the laser beam on the workpiece mark set carved text and drawings.
Computer software to identify specific marking collect any complex graphic images of text and graphics via two-dimensional codes and bar codes on the digital camera or scanner input downloaded from the Internet and computer production, produce a variety of tags, converts it into a digital signal, the programming on the calculation into a current control input signal and then drive to form the corresponding control signal by D / a precision servo motor control card operation, thereby control the direction of the x and y directions reflecting galvanometer deflection angle of the laser marking machine focusing the laser beam spot according to set patterns, text trajectory, the workpiece surface is etched to form a permanent score. Scribe line widths up to 20 microns, and the software with automatic image distortion correction function can achieve precise image marking.
