Principle of FPC UV Laser Cutting Machine

The cutting mode of the FPC ultraviolet laser cutting machine is divided into three types: a flying optical path, a collimating focusing mirror, and a galvanometer mode. Each has its own characteristics and uses. This article mainly explains the principle of galvanometer mode for FPC UV military laser pointer cutting machine.

Laser galvanometer principle: input a position signal, the swing motor (laser galvanometer) will swing a certain angle according to the conversion ratio of a certain voltage and angle. The whole process adopts closed-loop feedback control, which is composed of five control circuits, such as position sensor, error amplifier, power amplifier, position distinguisher and current integrator. The principle of the digital laser galvanometer is to convert the analog signal into a digital signal on the principle of the analog laser galvanometer. Scanning laser galvanometer is one of the core components of FPC UV laser cutting machine, and its cutting performance depends on the performance of scanning laser galvanometer.

The High Speed Scanning Laser Oscilloscope System is a high performance rotating motor designed specifically for optical scanning applications. The motor part uses a high-precision position sensor. Mainly used for fast and precise positioning of the beam. High-speed waterproof laser pointer galvanometer is the result of many years of experience in the development and production of industrial laser galvanometer scanning systems. A motor specifically designed for lens loading is able to achieve optimal scanning performance. Special handling of the bearing parts for long-term uninterrupted operation. The special design of the bearing enables the system to achieve the highest dynamic performance and resonance characteristics. The world's leading digital control method can effectively avoid various electromagnetic interferences in the working environment, and advanced control algorithms can ensure the system has faster response speed.

Photoelectric sensors used in high-speed scanning laser galvanometers have high resolution and very good repeatability with very small drift. The motor has a heating device and a temperature sensor, and it can work stably in the case of environmental fluctuations. In summary, the high-speed scanning laser galvanometer can ensure long-term stable operation.

The laser galvanometers currently used in China belong to the analog 488nm laser pointer galvanometer. The main implementation is the use of analog devices. Because the analog devices are easily interfered by the electromagnetic radiation of the surrounding environment, there will be scatter points, curved lines, and filling during use. Regular shading and other phenomena. The domestic analog laser galvanometer speed is slower than that of foreign countries, and its small step response time is above 300um.

The digital laser galvanometer uses digital signals to perform calculations to control the motor, which can effectively suppress environmental interference, and can be used normally even if the working environment is severely electromagnetically disturbed. The system adopts foreign control technology, and the system response speed is very high, basically surpassing the domestic laser galvanometer system of the same type. The motor adopts a special process, long life and stable and reliable performance.

In the process of FPC ultraviolet laser cutting machine, the galvanometer is an important component to ensure the processing quality and processing precision, and its stability directly affects the overall stability of the FPC usb laser pointer cutting machine.
