Composition and configuration of fiber laser marking machine

Fiber laser power supply: Laser power supply is a high-performance automatic ignition constant current power supply, divided into two types: continuous laser power supply and pulse laser power supply. Continuous laser power supply is a high-performance automatic ignition constant current power supply, and pulse laser power supply is specifically designed for pulsed Nd: YAG lasers.

Continuous laser power supply is a high-performance automatic ignition constant current power supply.

The power supply achieves high-precision constant current output through fixed frequency and width modulation. The output current ripple is small and the stability is high. The ignition part adopts a three-level continuous current method of series high-voltage arc ignition, LC secondary high-voltage relay, and low-voltage constant current continuous arc current, combined with ignition monitoring circuit, to achieve automatic ignition and achieve a success rate of over 99% in one ignition. The high-voltage pulse waveform rises slowly, and the intensity can be graded and adjusted to adapt to the dispersion of different breakdown voltages of Krypton lamps. At the same time, it can also reduce the sputtering of electrode materials and minimize the adverse effects of high-voltage triggering on the service life of Krypton lamps.

Pulse laser power supply is specifically designed for pulsed Nd: YAG lasers. Using a switch mode power supply, which is controlled internally by a microcontroller, is a true CNC power supply. By selecting parameters such as laser output power, frequency, and pulse width through the touch mode operation panel, users can program the laser pulse waveform and parameters through the keyboard to match the welding parameters with the welding requirements, achieving the best welding effect. Therefore, it can meet the welding needs of almost all metals and is an ideal configuration for multifunctional laser welding machines, with functions such as misoperation and automatic protection against overheating.

Main power control box: It is used to control the power supply.

Combination mirror: also known as a combination mirror. The function of a beam splitter is to indicate the optical path. Because 1064nm laser is invisible, and in the actual marking process, we often need to know where the laser focal point is in order to determine whether the marking position is correct. Through a beam combining mirror, we use the visible 650nm red light emitted by the diode to combine with the 1064nm laser to form a beam of light. This way, the 650nm red light refers to the position of the 1064nm laser, achieving the goal of using 650nm red light to indicate the 1064nm laser.

Fiber laser: Currently, the most commonly used brand is IPG, and of course, SPI is also useful. SPI's MOPO mode fiber laser also has great market prospects.

Digital galvanometer: Currently, the most commonly used ones are German SCANLAB galvanometer and RAYCUS galvanometer, while domestically produced ones include SUNNEY, HANS, etc.

Field lenses: Currently, the most commonly used ones are domestic brands. In terms of optical lenses, domestic effects are sufficient to deal with the most commonly used situations, so there is no need to look for imported brands.

Marking control cards: Currently, the most commonly used ones are SAMLIGHT, MarkStudio, and EZCAD, which also have a certain market.

Red light indicator: With this, we can visually see the size and position of the marking before it is done.

The casing and circuit parts are all designed and produced by the manufacturer themselves, of course, many are custom-made, which is why so many fiber optic machines have similar appearances.
