What is a fiber laser marking machine?

The so-called fiber laser marking machine means that the marking machine uses a fiber laser. The fiber laser has become a hot spot in laser physics research in recent years, and it has become the most likely new generation product to replace solid-state lasers. Fiber lasers can be developed based on fiber amplifiers: high power density is easily formed in the fiber under the action of the pump light, causing the laser energy level of the laser working material to "populate number inversion", when a positive feedback loop is properly added ( Forming a resonant cavity) can form a laser oscillation output. Fiber laser has the characteristics of small size (using air-cooled device), good beam quality, and maintenance-free. Fiber laser marking machine has become the most advanced laser marking equipment today. This article will provide you with relevant information about fiber laser marking machines.

working principle

The fiber laser marking machine irradiates a permanent mark on the surface of various materials through a laser beam. The marking process is to expose the deep material through the evaporation of the surface material, or the physical change of the surface material through light energy to "mark" traces, or the light to burn off part of the surface material to show the desired image. Output, such as text, bar code, and other types of graphics.

component

Fiber laser marking machine is mainly composed of laser, vibrating lens, and marking card. It uses a fiber laser to produce a laser marking machine. The beam quality is good. Its output center is 1064nm. The life of the fiber laser marking machine is about 100,000 hours. The laser marker has a longer life span, with an electro-optical conversion efficiency of about 28%. Compared with other laser markers with a conversion efficiency of 2%-10%, the fiber laser marking machine has a greater advantage and is superior in energy conservation and environmental protection.

Industry Application

The fiber laser marking machine is widely used for high-precision product identification such as integrated circuit chips, plastic translucent keys, IC chips, digital product components, precision machinery, industrial bearings, clocks, electronic and communication products, aerospace devices, medical equipment, building materials, and pipes.

There are also various graphics and text markings in various fields such as auto parts, home appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco, and military affairs, as well as mass production line operations.

Applicable materials

Fiber laser marking machine is suitable for metal and various non-metal materials, hard alloy, oxide, electroplating, coating, ABS, epoxy resin, ink, engineering plastics, etc.

main feature

The advantages of fiber lasers are: low manufacturing cost of glass fiber, mature technology, and the flexibility of fiber brings advantages of miniaturization and intensiveness. Because there is no optical lens in the resonant cavity of the fiber laser, it has the advantages of adjustment-free, maintenance-free, and strong stability, which cannot be compared with traditional lasers. Fiber lasers are capable of harsh working environments and have a high tolerance for dust, shock, impact, humidity, and temperature. There is no need for thermoelectric cooling and water cooling, just simple air cooling, which can greatly reduce the cost. High electro-optical efficiency: The comprehensive electro-optical efficiency is as high as 20%, which greatly saves power consumption during work and saves operating costs.

1. Fiber laser marking machine has more advantageous to process and mark materials with high hardness and high melting point and brittle materials.

2. The fiber laser marking machine belongs to non-contact processing, non-damaged products, no tool wear, and a high level of marking quality.

3. The laser beam of the fiber laser marking machine is thin, the processing material consumption is small, and the processing heat-affected zone is small.

4. The processing efficiency of fiber laser marking machines is higher, and it is easy to realize automation due to the use of computer control.
