take minutes to know the fiber optical laser
Firstly,The function of the focusing system is to focus the parallel laser beam at one point.
Secondly,The f-θ lens is mainly used. Different f-θ lenses have different focal lengths. The marking effect and
The range is also different.
The fiber laser marking machine uses imported high-performance focusing system. The standard configuration of the lens focal length f = 160mm, the effective scanning range.
Φ110mm. Users can choose the type of lens according to their needs.
Optional F-θ lenses are:
f = 100mm, effective focusing range Φ65mm.
f = 160mm, effective focusing range Φ110mm.
Computer control system
The computer control system is the center of the entire laser marking machine control and command, and it is also the carrier of software installation. Acousto-optic modulation system, galvanometer
The coordinated control of the scanning system completes the marking process on the workpiece.
The computer control system of the fiber laser marking machine mainly includes the chassis, motherboard, CPU, hard disk, memory module, D / A card, floppy drive, display, keyboard,Mouse etc.Features edit
There are two principles:
Firstly,”Hot working” a laser beam with a higher energy density (which is a concentrated energy flow) irradiates the surface of the material being processed, and the surface of the material absorbs the laser
Energy, which generates a thermal excitation process in the illuminated area, which causes the surface (or coating) temperature of the material to rise, causing metamorphosis, melting, ablation, evaporation, etc.
Secondly,”Cold work” (ultraviolet) photons with very high load energy,
can break chemical bonds in materials (especially organic materials) or surrounding media,to Non-thermal process destruction of the material.
This cold processing has special significance in laser marking processing because it is not thermal ablation,but it does not produce
“Heat damage” has the side effect of cold peeling that breaks the chemical bond, so there is no heating or thermal deformation on the inner layer and nearby areas of the processed surface.
For example, in the electronics industry, excimer lasers could? deposit a thin film of a chemical substance on a substrate material to create narrow grooves in a semiconductor substrate.
Comparison of different labeling methods
Compared with the inkjet marking method, the advantages of laser marking engraving are: a wide range of applications, a variety of substances (metals, glass, ceramics, plastics, leather, etc.)
high quality can permanently marking
but No force on the surface of the workpiece, no mechanical deformation, no corrosion on the surface of the material.
firstly it can engrave a variety of non-metallic materials.
for example? clothing accessories, pharmaceutical packaging, alcohol packaging, building ceramics, beverage packaging, fabric cutting, rubber products, Shell nameplate, craft gifts, electronic components, leather and other industries.
firstly 1. Can engraving metal and various non-metal materials. It is more suitable for processing some products that require fine and high precision.
secondly .Applied to electronic components, integrated circuits (IC), electrical appliances, mobile phone communications, hardware products, tool accessories, precision instruments, glasses, clocks,Jewelry, auto parts, plastic buttons, building materials, PVC pipes, medical equipment and other industries.
3. Applicable materials include: ordinary metals and alloys (iron, copper, aluminum, magnesium, zinc and all metals),
also rare metals and alloys (gold, silver, titanium), gold Metal oxides (all kinds of metal oxides),
special surface treatment (phosphating, aluminum anodizing, electroplated surface),
ABS material (appliances of electrical appliances,Daily necessities), inks (light-transmissive keys, printed products),
epoxy resins (electronic component packaging, insulation).
The most common laser marking machines on the market are mainly CO2 laser marking machines and YAG laser marking machines.
Later, semiconductors are using YAG laser marking machines gradually.
The laser marking machine has replaced it, and it has become the model with the largest market share in the laser marking machine.
In addition, there high-end end-pumped laser marking machines.
so Fiber laser marking machine, UV laser marking machine, etc.
With the development of science and technology,
also the electronics industry applying more and more the fiber laser marking machine ,
and its obvious characteristics? : integrated design, small size Low power consumption, long life, high efficiency, maintenance-free, high-quality laser beam, fine light spot, no consumables required.
