Fiber laser marking is an advanced technology in the industry world, one of the most popular applications based on this technology is the fiber laser marking machine. So, what are the components and the application purpose of this kind of machine? Please let me introduce that to you in the following contents.
Here is the content list:
l What are the components and working process of the fiber laser marking machine?
l What is the main application purpose of the laser fiber laser marking machine?
A fiber laser marking machine basically has three main parts, including pump, resonator, and beam delivery system. The pump includes a laser diode from which a light beam is emitted and transmitted through an optical fiber to a resonator, which contains a so-called gain medium. The resonator carries a gain medium. In simple terms, the medium is a fiber medium doped with rare earth elements. The main difference between different fiber laser applications is based on the generated wavelength, which determines the surface on which each type can be marked. fiber laser marking machines for metals and plastics are mainly doped, which provides them with the wavelength required for the best absorption rate to mark various metals and plastics. The resonator combines the gain medium with a set of fully reflective and semi-reflective Bragg grating components that allow refracting, amplifying, and filtering light waves to obtain the correct wavelength for the marking. The filtered beam is then transmitted to the beam delivery system, which is just a beam expander and a lens contained in the beam head. This is the "laser pointer" for marking. Flexibility is the main advantage of a fiber laser marking machine. Due to its versatility in marking various materials, it has become the most preferred marking machine in the industry.
Industrial applications of fiber laser marking machines are various, for example, the automotive industry has become one of the largest users of this technology. It is estimated that a car is composed of approximately 30,000 parts, which are made of steel, aluminum, copper, special fibers, or plastics, and vary in shape and size. All could be processed with fiber laser marking machines. A common application like mark information on the seat belt components, such as country of origin, serial number, and barcode, mark various components and buttons on the dashboard. These buttons need to be clearly visible during the day and illuminated at night. Therefore, the day and night marks are used. These methods can also be used to mark other materials, such as ceramics used to make spark plugs. You will also find fiber laser markings on engine blocks, car sensors, chassis VIN codes, and motorcycle parts. In this industry, one of the most concerning issues of markup is readability and traceability. Parts should be traced to their country of origin, and the markings should be machine-readable. Therefore, fiber lasers have increased in recent use. In integrated circuit industry, fiber laser marking machine is used very commonly as well. Integrated circuit components are the most important units used to construct circuits and systems. A fiber laser marking machine can be used for marking on integrated circuit boards and semiconductor components (including text and graphics). In the electronics industry, which is a really fast-growing industry, it is essential to prioritize efficiency and meet growing demand. This requirement also expects quality and safety. Televisions, laptops, and smartphones are all made up of tiny substances. Fiber laser marking is the most effective marking method in this industry because it can handle tiny elements without damaging surrounding materials.
