The Core Of Laser Cleaning - QYCLH-FPD Control System

Laser cleaning is called "the green cleaning technology with the most development potential in the 21st century". It can change the grain structure and orientation of the substrate surface without damaging the substrate surface, and can control the surface roughness of the substrate. Thereby enhancing the comprehensive performance of the substrate surface. With the accelerated industrialization process and the steady advancement of the "double carbon" goal, traditional cleaning processes have gradually replaced traditional cleaning processes in many fields, and have gradually become an indispensable equipment manufacturing technology in high-end manufacturing fields such as industry, military industry, shipbuilding, and aerospace.

With the rapid development of the laser cleaning industry, lasers are constantly developing in the direction of miniaturization. Handheld and mobile laser cleaning equipment have made laser cleaning technology used in a wider range of fields. Laser galvanometer scanning is mostly used on the laser head of laser equipment to control the scanning range and scanning speed during laser cleaning. At present, cleaning systems are mainly divided into continuous laser cleaning systems and pulse laser cleaning control systems. The application of continuous laser cleaning systems in China is relatively common and mature, but the development of pulse laser cleaning systems and continuous-pulse composite cleaning systems is slow.

 

 

 

SDQY Laser independently developed a new generation of QYCLH-FPD integrated control system for the field of laser cleaning, and developed dedicated hardware circuits and embedded software to achieve precise control of lasers and galvanometer systems, interaction with external electrical components, and HMI The interface for device interaction is not only suitable for domestic laser brands such as Raycus, but also for international brand lasers such as IPG. It supports one-dimensional galvanometer and two-dimensional galvanometer, and can be used with handheld pendulum laser cleaning and welding gun heads. It is also suitable for swing cleaning and welding gun heads. In addition, the control board supports serial communication and bus communication, which facilitates users to realize automated integration. , the system integrates 24V and ±15V power supplies, saving electrical costs and space at the same time. The size of the controller is only 103*92.5*33.5mm. It is currently the smallest and most comprehensive general-purpose composite control system for continuous-pulse laser cleaning in China. The system effectively improves cleaning efficiency and solves the problem of "match heads" at both ends of the linear cleaning process. The system It has been stably applied in batches in aerospace, rail transit, tire mold and other industries.

 

 

The QYCLH-FPD integrated control system has the following technical advantages:

 

It adopts a double-layer motherboard design to separate core general hardware and external interface hardware. It can develop multiple types of control capabilities on a unified development platform and is compatible with lasers of different types and manufacturers. It is also equipped with flexible universal input and output interfaces to meet the needs of Various customized control requirements; while the basic general communication interface meets the requirements of peripheral communication, the communication interface can also be flexibly expanded to achieve longer distance and higher reliability communication requirements.

 

The control hardware uses a single 24V power input interface, and other voltage requirements are integrated within the system, thereby reducing the number of external switching power supplies. The reliable power demand analysis and distribution strategy within the system also reduces maintenance costs. At the same time, it is equipped with positive and negative 15V power output interfaces, so that this control system can be used as control hardware and has the ability to externally drive the galvanometer system, solving the control power supply needs in the general laser cleaning field in one stop.

 

In order to satisfy various types of galvanometer hardware, the control system has both digital galvanometer protocol signal output and galvanometer analog drive signal output, achieving both flexibility and unity to meet the selection needs of different external hardware. The galvanometer control module adopts dual-axis signal output, which greatly improves customers' diversified needs for processes and broadens the process capabilities of the equipment.

Laser cleaning often requires efficient pulse lasers and high-speed galvanometers to achieve efficient cleaning requirements. The core of the control system uses a high-speed chip, coupled with high-efficiency code and algorithm logic, which can further increase the frequency of sending coordinate signals of the galvanometer on the basis of meeting the universal galvanometer protocol. It can also reduce the coordinate interval, achieving high-speed and delicate vibration. Mirror control, combined with efficient pulse laser, achieves more precise laser cleaning effects. On the other hand, the ultra-high-speed frequency also allows the chip to handle many types of external control requirements while handling galvanometer motion tasks, such as various data collection, external component control, and communication between devices.

 

The new generation integrated control system integrates highly integrated power management, galvanometer control, flexible universal input and output interfaces, and highly scalable communication interfaces; at the same time, combined with customizable embedded software, it can truly solve the complex problems of customers with multiple types of equipment. Process requirements. While achieving the above capabilities, the volume is only half or even smaller than that of a normal control system, making it more friendly to equipment integration capabilities.
