The core components of the 20W fiber laser marking machine are the main oscillator power amplifier (MOPA), Q-modulation, and high-frequency pulsed ytterbium doped fiber laser,High reliability DC power supply drives multi-mode semiconductor laser under the control of dedicated control card,The 970 ± 10nm laser emitted by a multi-mode semiconductor laser is coupled into a 5mm transmission fiber with a metal sheath, resulting in the generation of 1.Laser with a wavelength of 06 microns,The laser is continuously amplified and beam expanded during transmission. The expanded laser beam is projected onto the galvanometer scanner, and the galvanometer is rapidly rotated and the laser is turned on and off by computer control to scan the laser beam in the X and Y directions. The laser beam is then focused by an F - θ lens to form a light spot with a diameter of several micrometers, which acts on the processed workpiece, causing the surface to be instantly ablated and vaporized,Finally, various graphic symbols are formed on the surface of the workpiece as needed.

Product Introduction

The 20W fiber laser marking machine uses a fiber laser to output laser, which is then scanned by an ultra high speed scanning mirror system to achieve marking function. It has high electro-optical conversion efficiency and is cooled by air cooling. The whole machine is compact in size, with good output beam quality, high reliability, and long operating life. It is energy-saving and can be widely used in various assembly line flight marking and high-speed static marking industries. It can meet various high-precision and high-efficiency laser marking needs. It adopts world leading fiber lasers and imported spare parts, with high marking accuracy, fast speed, stable performance, and long life.

The 20W fiber laser marking machine can engrave metal materials and some non-metal materials, mainly used in fields that require high depth, smoothness, and precision, such as stainless steel decorative pieces for mobile phones, clocks, molds, etc IC、 In industries such as mobile phone buttons, bitmap marking can create exquisite images on surfaces such as metal and plastic, and the marking speed is 3 to 12 times faster than traditional first generation lamp pump marking machines and second-generation semiconductor marking machines.
