Laser marking machines have gradually become the upstarts in the marking industry. The laser marking machines on the market are divided into laser equipment such as ultraviolet, semiconductor machines, optical fibers, and carbon dioxide. So different types of laser marking machines are suitable for different industries. How should we go about it? After using it, today I will take a look at the characteristics and differences between UV laser marking machine and semiconductor laser marking machine with the editor.
The UV laser marking machine is developed with a 355nm UV laser. The 355 UV light has a very small focusing spot, which can greatly reduce the mechanical deformation of the material and has a small processing heat effect, so it can perform ultra-fine marking and special material marking. It is the first choice for customers who have higher requirements on the marking effect.
Ultraviolet laser marking machine has been used in the high-end market of ultra-fine processing, surface marking of packaging bottles of mobile phones, cosmetics, medicines, food and other polymer materials, marking and scribing of flexible PCB boards, micro-holes of silicon wafers, Blind hole processing, LCD liquid crystal glass, glassware surface, metal surface coating, plastic buttons, electronic components, gifts and other fields.
1. High precision
Ultraviolet laser marking machines have particularly high precision and are often used in the high-end market for ultra-fine processing.
2. Cold working
Ultraviolet laser cold processing does not generate heat. Because of the working method that does not generate heat, the ultraviolet laser processing method becomes cold processing, which is also different from traditional lasers.
3. High photoelectric conversion rate
Ultraviolet laser marking machine has high photoelectric conversion rate, low power consumption of the whole machine, and long service life of nonlinear crystal.
The semiconductor laser marking machine adopts a semiconductor array, and uses a semiconductor light-emitting diode with a wavelength of 808nm to pump the Nd:YAG medium to form a laser output mode with a wavelength of 1064nm. The laser is small in size and high in photoelectric conversion efficiency.
Semiconductor laser marking machine is suitable for metal and a variety of non-metallic materials, requiring fine marking and high precision. Used in electronic components, hardware products, tool accessories, integrated circuits (IC), electrical appliances, mobile communications, precision instruments, glasses and watches, jewelry, auto parts, plastic buttons, building materials, PVC pipes, PPR pipes, medical equipment, etc. The industry belongs to the universal laser marking equipment.
1. Wide range
Semiconductor laser marking machine is suitable for metal and a variety of non-metallic materials, with a wide range and high speed.
2. High power and high thermal effect
The working temperature range of semiconductor laser marking: 0℃～40℃, the light spot mode can be changed by grating, especially suitable for fine graphic marking, the marked characters have good color contrast, smooth and delicate hand feel, neat edges, excellent appearance effect, can be Comparing with similar foreign equipment, it can also achieve a good spot pattern without grating.
3. Low power consumption
The semiconductor has the advantages of good stability, power saving, and no need to change the lamp. The average power consumption is 2KW/h, but the laser has a relatively long service life. Generally, it is about 8000-10000 hours under normal use conditions, which is especially suitable for long-term on-site use. operation of time.
4. The anti-vibration and impact ability has reached the national level 01 standard.The semiconductor laser marking machine is less affected under the harsh conditions of the production environment, and the failure rate is low when the machine is subjected to vibration, shock and high temperature.
After reading the basic information of the above-mentioned ultraviolet laser marking machine and semiconductor laser marking machine, we all have a certain understanding, so what is the difference between them, how should we start, let's take a look at the ultraviolet laser marking machine The difference between the marking machine and the semiconductor laser marking machine.
1. The ultraviolet laser marking machine has a smaller focused spot and a small processing heat affected zone, which belongs to cold processing, and the semiconductor laser marking machine belongs to thermal processing.
2. The semiconductor laser marking machine has a wider range of use, faster and higher efficiency,and the ultraviolet laser marking machine is better at meticulous processing.
3. The power of the semiconductor laser marking machine is high, and the power consumption of the ultraviolet laser marking machine is low.
4. The semiconductor laser marking machine has stronger anti-vibration and impact ability.
