Laser marking machine is to use laser beam to make permanent marks on the surface of various materials. The effect of marking is to reveal the deep material through the evaporation of the surface material, so as to engrave exquisite patterns, trademarks and characters, and apply it to some occasions that require finer and higher precision.
Widely used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, glasses clocks, jewelry, auto parts, plastic buttons, building materials, PVC pipes.
Main components of laser marking machine
1. Laser source
Laser is the core accessory of laser marking machine. According to different models, it usually has many series of lasers: such as optical fiber, ultraviolet, CO2, YAG, semiconductor and so on.
The quality of the laser directly determines the use effect and service life of the laser marking machine. At present, in the laser market, IPG, MAX, Raycus and other brands of lasers are the most common.
2. Galvanometer
The galvanometer is also an important part of the laser marking machine, which affects the processing speed and processing accuracy of the laser marking machine. It consists of two parts: controller and vibrating head.
It has the advantages of large scanning angle, large peak torque, large load inertia, and fast working speed.
It can be divided into X-direction scanning system and Y-direction scanning system, and a laser reflector is fixed on each servo motor shaft.
3. Focusing mirror
It focuses the parallel laser beams on one point. The f-theta lens is mainly used. Different f-theta lenses have different focal lengths, and the marking effect and range are also different.
Among them, the fiber laser marking machine adopts imported high-performance focusing system. The standard lens focal length is f=160mm, and the effective scanning range is Φ110mm. Users can choose the type of lens according to their needs.
4. Laser marking system
Including laser marking card and marking software, it is the window for users to connect with equipment. It has rich and perfect drawing functions, controls the marking parameters, controls the debugging application interface, and operates all marking actions. BJJCZ marking card and EZCAD marking software are common in the market.
