Take you to judge the quality of fiber laser marking machine
First look at the quality of its laser, because the laser is the most important part of the entire fiber laser marking machine, and its quality determines the fiber laser The quality of the marking machine, generally speaking, the imported laser is better, its beam quality is good, the electro-optical conversion rate is high, the domestic laser is slightly inferior, but the domestic laser can also meet the needs of any industry, so if the funds are not very sufficient In some cases, domestic lasers can also be used.
Secondly, depending on whether the cooling equipment of the fiber laser marking machine is good, it can be judged from the following aspects: .
1. How about the cooling water flow rate, the faster the cooling water flow rate, the more helpful for heat dissipation.
2. Whether the water pipe of the cooling system is leaking, if there is dew, it will also affect the power of the laser.
After Z, it depends on the quality of the laser lens of the fiber laser marking machine. Generally, the better the laser lens is, the more lasers the anti-laser marking machine emits, and the smaller the laser loss is. , This is conducive to increasing the electro-optical conversion rate of the fiber laser marking machine. The imported lenses, domestic lenses, and domestic lenses are divided into two types, which are produced with imported materials and those produced with domestic materials. The price difference is very large. The difference in lifespan is also huge.
Laser marking machines are usually classified as fiber optic, ultraviolet, CO2 carbon dioxide laser marking machines. Except for some optical accessories and different organizational principles, most of the other configurations are usually It can be divided into the following categories.
From the principle structure of the laser marking machine, the illustrated anatomy is as follows:.
The composition of the laser marking machine has the following supporting systems: .
First, the focusing system.
The function of the focusing system is to focus the parallel laser beam on one point, mainly using f-theta lens. The results and scope of the marking machine are also different. The fiber laser marking machine adopts imported high-performance focusing system. Its standard lens focal length is fu003d160mm, and the effective scanning range is Φ110mm. Users can choose the type of lens according to their needs.
Second, the golden model.
The model architecture of the entire device.
Third, the computer control system.
The computer control system is the control and command center of the entire laser marking machine, and it is also the carrier of software installation. Through the coordinated control of the acousto-optic modulation system and the galvanometer scanning system Finish marking the workpiece.
Fourth, the laser power supply.
The laser power supply of the laser marking machine is a device that provides power for the laser. Its input voltage is AC220V alternating current, which is installed in the control box of the marking machine.
Fifth, the laser.
This is the core accessory of the laser marking machine. Depending on the model, IC automatic laser marking machine usually has many series of lasers: fiber, ultraviolet, CO2, YAG, semiconductor, etc., the output laser mode is good and the service life is long, and it is designed to be installed in the casing of the marking machine.
Sixth, galvanometer field mirror scanning system.
The galvanometer scanning system is composed of an optical scanner and a servo control. The galvanometer is composed of three parts: a stator, a rotor, and a detection sensor. Technology, new material, new process, new working principle design and manufacture.
The optical scanner adopts a servo motor with moving magnetic deflection working mode. The optical scanner is divided into an X-direction scanning system and a Y-direction scanning system, each of which is fixed on the axis of the servo motor. With the laser mirror, each servo motor is controlled by a digital signal from the computer to control its scanning track.
Seven, marking control software.
Laser marking machine software is used to control marking parameters, control the application interface of debugging, and operate all marking actions.
The , essentially perfected by date printing machine, is one of the first home appliance to be widely distributed.
