What is a picosecond laser marking control system

Picosecond laser is a type of laser specifically designed for precision machining. Picosecond laser is a laser with an extremely short pulse width, which is within the range of picoseconds (1 picosecond=10 ^ -12 seconds). Due to the extremely short signal period of picosecond laser, it can accurately cut or mark extremely fine patterns.

Picosecond laser marking is one of the widely used technologies in high-precision machining, and is widely used in the production and manufacturing process of biomedical devices, precision optical components, solar panels, and other products. Picosecond laser marking requires the use of specialized picosecond laser marking machines, whose main core components include lasers, transmission systems, control systems, and other components.

The picosecond laser marking control system is the control core of the picosecond laser marking machine. Operators issue instructions to the machine through the control system to complete processing tasks. The picosecond laser marking control system is also a type of CNC system, which can set the processing method, processing time, and processing frequency in advance. After completion, the machine can start processing and operate independently without the need for additional personnel to constantly monitor, saving manpower and improving efficiency.

There are many picosecond laser marking control systems on the market, and we can consider the selection based on algorithms, stability, accuracy, and other factors. The algorithm is the technical core for controlling the motion of the marking machine. The laser marking machine adjusts the laser's motion trajectory by controlling the galvanometer motor. An excellent algorithm can make the laser's motion trajectory smoother, and even very small graphics should be clearly displayed during processing.

Stability is another important performance of control systems, and industrial production often requires long-term continuous operation. A stable laser marking control system should ensure that there is no disconnection or machine jamming during this period. In addition, the electromagnetic environment of the factory is very complex, and a qualified control system should also have specialized measures to prevent abnormal connections caused by electromagnetic interference.

Accuracy is the easiest part to measure, and the machining accuracy of the control system can be obtained by continuously marking and measuring precision patterns. However, the final machining accuracy of a laser marking machine is not determined by the control system. The laser, motor, and transmission system also have a crucial impact on accuracy. Therefore, it is necessary to investigate and debug one by one during testing to achieve the best operating state.
