Laser marking machines use laser beams to permanently mark the surface of a variety of different substances.Play the effect of mark is through material surface evaporation show deep material, so beautifully carved patterns, logos and text, laser marking machine is mainly divided into, 

CO2 laser marking machine, semiconductor laser marking machine, fiber laser marking machine and YAG laser marking machine, laser marking machine is mainly applied to some more fine and higher accuracy required.Applied to electronic components, integrated circuits (IC),electrical appliances, mobile phone communication, hardware products, tool accessories, precision equipment, glasses and clocks, jewelry, auto accessories, plastic keys, building materials, PVC pipe.

 


1)Basic principles:

Laser marking is the use of a laser beam to permanently mark the surface of a variety of different substances.The marking effect is to reveal the deep material through evaporation of the surface material, or to "carve" the trace through the chemical and physical changes of the surface material caused by light energy, or to burn off part of the material by light energy, showing the patterns and words needed to be etched.

 


2)Composition structure:

1. Laser power supply

Laser power supply of optical fiber laser marking machine is a device that provides power for optical fiber laser, and its input voltage is AC220V.Installed in the control box of marking machine.

2. Fiber laser

Optical fiber laser marking machine adopts imported pulsed optical fiber laser, its output laser mode is good with long service life, and is designed to be installed in the marking machine case.

3. Vibroscope scanning system

The vibroscope scanning system is composed of optical scanner and servo control.The whole system adopts new technology, new material, new process and new working principle to design and manufacture.The optical scanner adopts a servo motor with dynamic magnetic deflection.It has the advantages of large scanning Angle, large peak torque, large load inertia, small electromechanical time constant, fast working speed, stability and reliability, etc.The precision bearing clearance mechanism provides the error of overbottom axial and radial runout."Electronic torsion bar" replaced the traditional elastic material torsion bar, greatly improving the service life and reliability of long-term work;The operating principle of zero power maintenance at any position not only reduces the power consumption, but also reduces the heating effect of the device and saves the thermostatic device.Advanced high stability precision position detection sensor technology provides high linearity, high resolution, high repeatability, low drift performance.The optical scanner is divided into x-direction scanning system and y-direction scanning system.Each servo motor shaft is fixed with laser reflecting lens.Each servo motor is controlled by a digital signal sent by the computer.

4. Focus system

The focusing system focuses parallel laser beams on a single point.Mainly USES the f - theta lens, different f - theta lens focal length is different, marking effect and scope is different also, fiber laser marking pause with imported high-performance focus system, the standard lens focal length f = 160 mm, effective scanning range Φ 110 mm.Users can choose the type of lens according to their needs.

Computer control system

The computer control system is the control and command center of the whole laser marking machine, and also the carrier of software installation.Through the coordinated control of the acousto-optic modulation system and the galvanometer scanning system, the marking processing of the workpiece is completed.The computer control system of optical fiber laser marking machine mainly includes chassis, motherboard, CPU, hard disk, memory chip, D/A card, floppy drive, monitor, keyboard, mouse and so on.
