Interpretation of the structure of laser marking machine

As the most advanced and widely used laser engraving and marking equipment on the market, laser marking machines can greatly improve the efficiency and quality of operations, ranging from automated mass production of enterprises to personal customization. . So what is the internal structure of the laser marking machine, and what are the main parts? Today, the editor will take you to understand the internal structure analysis of the laser marking machine.

Analysis of the internal structure of the laser marking machine

First, the laser

The laser is the core accessory of the laser marking machine. the main source of light. Depending on the model, it usually has many lasers with different light sources, such as 1064nm wavelength fiber, 532nm UV, 4064nm CO2, YAG, semiconductor, etc. Laser marking machine has the advantages of marking efficiency, long service life and low maintenance cost.

Second, the laser tube

The laser tube is also the heart of the laser marking machine. The price of imported laser tubes from the United States is very expensive. At present, the domestic production level is constantly improving, and the technology is constantly updated. The domestic laser tubes still have high stability and high precision, so most laser marking machine factories use domestic laser tubes. The service life of a good quality laser tube is generally about 12,000 hours.

Third, the focusing system

The function of the focusing system is to focus the parallel laser beam on a point, which is related to the power of the laser marking machine, It mainly uses f-theta lens. Different f-theta lenses have different focal lengths, and the marking effect and range are also different.

Fourth, the industrial computer system

The industrial computer system is the center of the control and command of the entire laser marking machine, and it is also the carrier of software installation. The workpiece marking processing is completed through the coordinated control of the acousto-optic modulation system and the galvanometer scanning system.

5. Laser scanning system

The laser scanning system is composed of optical scanner and servo control. The vibrating lens consists of three parts: stator, rotor and detection sensor. The whole system is designed and manufactured with new technology, new material, new process and new working principle.

6. Laser marking software

Laser marking machine software is used to control marking parameters, control the application interface of debugging, and operate all marking action. Laser marking software, marking card is the dominant operating system of the laser marking machine, which determines the operational stability of the laser marking machine. It mainly controls the movement of X, Y and Z axes, and also controls the output power of the laser.

Seven, stepping motor

The quality of the motor affects the marking accuracy of the laser marking machine. Some manufacturers choose imported stepping motors. And some are stepper motors produced by joint ventures, and some smaller companies usually choose non-brand motors.

Eight, sheet metal cabinet frame

Nine, laser power supply

The laser power supply of the laser marking machine is a device that provides power for the laser, and its input voltage is AC220V alternating current.

Whether a laser marking machine is of good quality depends on the quality of its laser accessories The marking stability is also very good.
