What is the core technology of laser control system

The laser motion control system is located in the upstream group of the entire industry. Through the integration of key technologies such as computer-aided design technology, numerical control technology, computer manufacturing, it covers all aspects related to laser processing, such as typesetting, feeding, cutting, welding, and so on. In order to ensure the good operation of all links, it provides a complete set of system solutions and is an essential component of the normal operation of laser equipment.

The main application scenarios of the laser motion control system are laser cutting, laser marking and laser welding, covering most metal and non-metallic materials, which can be said to be widely used. In daily processing and production, the accuracy, efficiency, stability and many other indicators of the laser depend on the real-time instructions of the motion control system, so it is very important to select a suitable control system.

Back to the laser motion control system, its core technology mainly includes the following five aspects:

1. Computer aided design technology: through computer modeling or reading the processing model from external files, carry out graphic recognition, editing and optimization processing, typesetting on the processing materials, and output the model to be processed.

2. Computer aided manufacturing technology: after the input of the processing model, the laser processing instructions are output according to the relevant technological requirements of the material, including laser power, pulse frequency, focus control, optical path path, auxiliary gas, etc. With the help of the algorithm, the processing path is optimized, the drilling position is set, and the processing scheme of complex graphics is completed with the optimal solution.

3. CNC technology: output the operation instructions of external equipment such as motor, motion axis, laser head, control the equipment to implement the specific processing details, and complete the specific laser processing operation together with the laser output instructions, which plays a key role in the processing of multi-axis platform.

4. Sensor technology: optimize the processing efficiency and improve the intelligence level by monitoring the temperature, pressure, air pressure, distance between laser head and material and other factors in the processing process. The sensor technology enables the laser to process curved surfaces and irregular surface materials, and realize the following processing, three-dimensional processing and other difficult technologies, typically the overall cutting and welding of automobile sheet metal parts.

5. Hardware design technology: according to the needs of the laser industry, develop corresponding embedded software and hardware circuits, mainly for security and stability, such as equipment failure alarm, equipment safety alarm, cooling system monitoring, software encryption, etc.

The domestic laser control system manufacturers are mainly concentrated in the medium and low power fields, and the three companies, Pachau Electronics, Weihong Shares and Orsendico, have occupied most of the market shares. In the subdivided fields, many leading players have also emerged. For example, the motion control system of Ruida Technology is in the leading position in the medium and low power CO2 laser equipment. In terms of medium and high power, foreign enterprises such as Siemens and Bev have the advantage.

At present, laser processing is constantly expanding its territory in high-end manufacturing industries such as 5G communication, chip manufacturing, curved screen, photovoltaic, precision parts processing, new energy vehicles, and is one of the most dynamic processing technologies in the new generation.
