Laser marking machines are divided into YAG laser marking machines, CO2 laser marking machines and semiconductors according to the difference of lasers. The main difference lies in the difference of lasers, and the difference of lasers is different laser wavelengths. Among many laser marking machines, fiber laser marking machines are relatively expensive. There is a reason why you are expensive. Let's take a look at the advantages of the fiber laser marking machine over other laser marking machines.


The advantage of fiber laser marking machine is actually the advantage of fiber laser. Advantages of fiber laser in laser marking A. good beam quality. The fundamental transverse mode output of TEM00 is close to 1, and the beam divergence angle is 0.24mrad; B. High pulse repetition frequency, stable output power, single pulse energy fluctuation less than 1%, so that high-speed laser marking can be realized, and the size, depth and shape of the spot can be accurately controlled; C. The plug efficiency is up to 20%, and the electro-optical conversion efficiency is up to 70%; D. Strong environmental adaptability, can work continuously under high vibration and high humidity environment. E. No water cooling device, small size, high efficiency, high reliability, long-time maintenance free, saving the use cost.


The light source is a laser secondary light driving power source. The fiber laser controller is used to control the working state of the fiber laser, and the control microcomputer of the marking machine controls the laser output through it. The galvanometer system is an important part of the fiber laser marking system. The laser goes out of a specific track on the parts to be marked through the movement of the galvanometer. F-Q mirror is a laser beam focused on the workpiece surface.


In the work flow of galvanometer system. There are two mirrors driven by high-precision servo motors in the galvanometer system. The servo motor rotates the angles of the two mirrors respectively under the control of the microcomputer. The laser beam is reflected by the two mirrors and focused to different positions of the workpiece by the F-Q mirror. Input the text and pattern to be marked through the special marking control software on the microcomputer, set the size of the text and pattern, the total marking area, the travel speed of the laser beam and the number of times to be repeated, and the galvanometer can move under the control of the microcomputer to control the laser beam to mark the set text and pattern on the workpiece.


The computer special marking software can identify and collect complex planar images, graphics and characters, two-dimensional codes and bar codes that are input through digital cameras or scanners, downloaded from the Internet and produced in the computer, make various marks, convert them into digital signals, convert them into current control signals through programming calculation, and then input them to the driver to form corresponding control signals and control the operation of high-precision servo motors through D / a cards, Thereby controlling the reflection in the X direction and the Y direction, respectively. The deflection angle of the galvanometer makes the laser beam focus spot move according to the set pattern and the character track, and etches on the workpiece surface to form a score. The scribe line width can reach the order of 20 μ m, and the software has the function of automatic image distortion correction, which can realize precise image marking.
