Fiber laser cutting machine has a waveguide type structure
The fiber laser cutting machine has a waveguide structure, which can generate a higher power density in the fiber core. The silicon optical fiber technology it is based on is now very mature, so high-precision, low-loss optical fibers can be produced. If the choice of fiber makes the pump and signal wavelengths operate in a single-mode operating state, the coincidence between the pump and signal light fields is very good. Due to the geometrical characteristics of the optical fiber, this structure has a high area-to-volume ratio, so its heat dissipation effect is very good.
This article mainly introduces the generation and development of laser technology, as well as the background and development problems of the combination of marking machine and laser, the structure of fiber laser cutting machine, and then the desktop guidance coordinate system The design in the marking machine is analyzed in key points. Optical system conditions of fiber laser cutting machine based on triangulation ranging method: provide theoretical support for the optical system for the realization of the automatic focus function of laser marking. Based on the recognition of laser marking technology and the principle of fiber laser cutting machine, through the analysis of the actual application status of fiber laser cutting machine at home and abroad, it is considered that it is necessary to realize the automatic focus function of laser marking. Considering the accuracy of distance measurement, the optical path part of the system can be constructed by the triangulation distance measurement method. Through the analysis and derivation of the triangulation distance measurement principle and programming assistance, the relationship between the main optical parameters and the position and size relationship of the optical system are found. The actual application design provides a theoretical basis.
The status quo and development trend of fiber laser cutting machines: my country's commercial fiber laser cutting machines are currently all dependent on imports. The reason is that we have not realized the commercialization and industrialization of fiber laser cutting machines. The development of fiber laser cutting machines in my country is actually not lagging behind. Several units have achieved continuous output power of more than 200W, but the industrialization of fiber laser cutting machines in my country is obviously lagging behind.
Let’s analyze the reasons for the lagging development of the industrialization of fiber laser cutting machines in my country.
Although there are many units engaged in the production and development of optical fiber devices in my country, the overall technical level is relatively weak. When optical communications is at a low point, relevant units basically can only choose to support or There are two ways to shut down the production line, unable to invest huge resources in the research and development of energy fiber devices. Therefore, when the rapid development of all-fiber laser cutting machines puts an urgent need for energy fiber devices, my country is basically a blank in this regard. For the earliest units engaged in the development of fiber laser cutting machines in my country, in the face of this domestic situation, there is basically no basis for the development of all-fiber laser cutting machines. Therefore, the solution of lens shaping and focusing end-pumped external cavity structure has become a reality. select. This kind of structure is very close to the traditional all-solid-state laser, and the dependence on fiber technology is very low, and it can be manufactured with non-fiber technology. However, practice has proved that only the all-fiber structure of the fiber laser cutting machine can fully reflect the overall consistency, integrity, harmony and matching. The use of the fiber laser cutting machine fully demonstrates the advantages of the fiber laser cutting machine. Therefore, the all-fiber structure solution is more in line with the fiber The essential law of the development of laser cutting machines, therefore, it is inevitable that all-fiber laser cutting machines will become the mainstream solution in the world.
