The structure of the laser marking machine

Laser power supply

Fiber laser marking The marking machine laser power supply is a device that provides power for the fiber laser, and its key-in voltage is AC220V. Installed in the marking machine control box.

Fiber laser

The fiber laser marking machine uses imported pulsed fiber laser, which has a good laser output method and long service life, and is designed to be installed in the marking machine housing.

Galvanometer scanning system

The galvanometer scanning system is composed of an optical scanner and a servo control. All systems are designed and manufactured using new technologies, new materials, new processes, and new working principles.

The optical scanner uses a servo motor with a moving magnetic deflection method. It has the advantages of large scanning angle, large peak torque, large load inertia, small mechanical and electrical engineering time constant, fast working speed, stability and reliability. Bearing anti-backlash organization provides ultra-bottom radial and axial vibration errors; 'electronic torque bar' replaces the traditional elastic material torque bar, further improving the service life and the reliability of long-term work; the principle of zero power maintenance at random parts is both Reduce the use of power consumption, and reduce the heating effect of components, eliminating the need for temperature control equipment; high-reliability part inspection sensing technology provides high linearity, high resolution, high repeatability, and low drift characteristics.

The optical scanner is divided into an X-direction scanning system and a Y-direction scanning system, and a laser reflection lens is fixed on each servo motor shaft. Each servo motor is controlled by a digital signal from the computer to control its scanning movement track.

Focusing system

The function of the focusing system is to focus the laser beam on the parallel plane to one point. The key is to choose f-θ lens. Different f-θ lenses have different focal lengths, and the actual marking effect and scope are also different. The fiber laser marking machine adopts an imported performance focusing system, and its standard lens focal length fu003d160mm, The reasonable scanning range is Φ110mm. Customers can choose lenses of model specifications according to their requirements.

The optional F-θ lens is:

fu003d100mm, reasonable focus range Φ65mm.

fu003d160mm, reasonable focus range Φ110mm.

Computer control system

The computer control system is the control and command center of all laser marking machines, and it is also the carrier of software installation. According to the coordinated control of the light control deployment system and the galvanometer scanning system, the marking of steel parts is solved.

The computer control system of the fiber laser marking machine mainly includes the main box, motherboard, CPU, solid state disk, memory stick, D/A card, floppy drive, display screen, computer keyboard, mouse, etc.

In the office, various are considered essential since they are used to achieve particular tasks in the office. Among these , cij printer, expiry date printing machine, and date printing machine are widely used.

LEAD TECH Technology Co., Ltd. also values the time, skills, and expert opinions of our staff. We are committed to providing fair and living wages, reasonable, structured work schedules, and clear duties and spheres of rights and responsibilities for each team member.

cij printer also offers several other date coding machine that could potentially be useful for manufacturers.

As the manufacturing procedure of cij printer becomes more regulated, the costs to businesses will increase and the workforce will suffer as a result.

LEAD TECH Technology Co., Ltd. who primarily serve our consumers need to consider offering their products in an expiry date printing machine such as cij printer to take advantage of the growing interest from consumers in supporting date printing machine.
