Fiber laser marking machine uses laser fiber as the medium, and has the advantages of good heat dissipation, high power, and fast speed, which are favored by many industries. Fiber laser marking machine uses air-cooled laser diode as the pump source, which can work in pulses and continuously, and is more convenient to use. Speaking of this, do you know how many accessories a fiber laser marking machine is composed of?
1. Fiber laser: That is, the component that generates laser, which is a laser that uses rare earth-doped glass fiber as the gain medium, so it is the core part of the entire fiber laser marking machine. The application range of fiber laser is very wide, including laser fiber communication, laser space long-distance communication, industrial shipbuilding, automobile manufacturing, etc. Its brands are both domestic and imported.
2. Galvanometer: The so-called galvanometer can also be called an ammeter, because its design idea is completely based on the design method of the ammeter, but the lens replaces the needle; it is mainly used for laser marking, laser engraving, etc.; the galvanometer used by the fiber laser marking machine is a digital galvanometer, which is generally a 10mm spot.
3. Field lens: Also called flat field focusing lens, scanning lens, f-θ lens, mainly used to focus the light from the galvanometer on a plane. Tips: When purchasing, pay attention to the marking range and determine it according to your needs. Don't blindly pursue size or price.
4. Marking card: Also called laser control card, laser marking card. It is used to convert the text patterns we draw in the computer into analog signals or digital signals, and then transmit them to the galvanometer.
5. Red light indicator: Also called red light pen, used to indicate the light path, because the 1064nm laser is invisible, and the 650nm light of the red light indicator is visible. The 650nm light is overlapped with the 1064nm light through the beam combiner, so where the 650nm light indicates, the 1064nm light is there, so as to achieve the function of indicating the light path. The red light pen is installed in the red light beam combiner frame.
6. Beam combiner: Also called light combiner. The function of the beam combiner: Used to indicate the light path. Because 1064nm laser is invisible, and in the actual marking process, we often need to know where the laser focus is, so as to determine the marking position.
7. Fiber laser marking machine cabinet: Also called fiber laser marking machine cabinet, laser control cabinet. If a marking machine is compared to a house, then the cabinet is the frame of the house, and all other accessories are installed in this house.
8. Industrial computer: You can also use an ordinary computer. For the fiber laser marking machine, because its marking card is a USB marking card, this computer can also use a laptop, which is one of the important reasons why the fiber laser marking machine can be made into a portable marking machine.
In addition to the above, the fiber laser marking machine also has a fiber laser power supply, a main power control box (if it is a portable marking machine, it is generally not installed, and it is better to install a larger one), and a red light beam combiner frame.
Fiber lasers are now used in all fields, including fiber optic communication, laser space long-distance communication, industrial shipbuilding, automobile manufacturing, laser engraving, laser marking, laser cutting, printing rollers, metal and non-metal drilling/cutting/welding (brass welding, quenching, cladding and deep welding), military defense security, medical equipment, large-scale infrastructure, etc.
So how do we operate a fiber laser marking machine?
Just enter the text and pattern to be marked in the software of the laser marking machine, confirm the size of the mark, the speed of the laser beam and the number of repetitions required, and the laser marking machine can mark beautiful patterns. We can design the patterns required for marking by ourselves, such as QR codes and barcodes, or import them through digital cameras and scanners, or download the floor plan from the Internet. These patterns are converted into digital signals, which are converted into current control signals through programming and calculation and then input into the driver to form corresponding control signals and control the operation of high-precision servo motors through D/A cards, and then the deflection angles of the reflective galvanometer in the x and y directions are controlled separately to produce satisfactory laser patterns.
