The main equipment of the automatic fiber laser cutting machine control system
The main equipment of the automatic fiber laser cutting machine control system is as follows:
(1) Processor: The processor of the embedded automatic fiber laser cutting machine control system is divided into main processor and assistant Processor 2 mostly. Among them, ARM is the core component of the control system, and its main function is to identify data and generate initial control signals. In addition, the processor is also responsible for reading out the marking object in time, controlling the marking speed and position information, and calculating the compensation standard data in a timely manner to assist the processor FPGA: FPGA as the ARM connected to the system bus of the ARM main processor The external storage method is the control system of the auxiliary processor. The FPGA receives and interprets through DA conversion, generates control signals, and enhances the processing circuit through the driver. At the same time, some external interrupt request signals are added to form a control command to control the servo system driver and Laser scanning galvanometer laser cutting In addition, the auxiliary processor FFGA is also responsible for processing key events, reading the key values u200bu200bof the matrix keyboard, processing photoelectric detection signals and emergency stop requests, and notifying the main processor.
2) USB interface: USB is the storage device of the fully automatic fiber laser cutting machine, which can realize the functions of copying, saving and transmitting marked files. Compared with the general automatic fiber laser cutting machine, the USB interface of the embedded automatic fiber laser cutting machine has better versatility and expansion performance. It can not only store various types of files, but also automatically identify duplicate content. Content, thereby saving storage space
(3) Liquid product display and touch keyboard: Liquid crystal display is the output device of LCD display to present various operating information of the system, and the embedded automatic fiber laser cutting machine adopts Touch keyboard, which integrates the keyboard and the display into one.
4) Laser and scanning galvanometer system: The high energy of the laser is reflected by the deflection and reflection of the galvanometer, and can be gathered to the target area of u200bu200bthe marking object, causing physical and chemical changes in the marking area, and passing The X, Y axis galvanometer laser beam deflection in the high-speed galvanometer optical scanning system realizes the rapid, positioning and rapid movement of the laser beam
(5) Transmission mechanism and speed measurement Device: The operation of the marking production line requires a stable movement speed. The embedded full-automatic fiber laser cutting machine can measure the marking speed of the laser beam through a real-time speed measuring device, and feed it back to the controller, and then compensate the marking position through the controller Then output the data
6) Safety classification procedure: When the design of the automatic fiber laser cutting machine control system causes the automatic fiber laser cutting machine to fail to work, it may cause The control system crashed. In comparison, the embedded automatic fiber laser cutting machine improves the safety of the control system, and sets the system safety inspection program, which can detect the safety of the system in real time. The safety of the control system of the embedded automatic fiber laser cutting machine is divided into 3 levels. One level is the security level. Under this level, the control system can perform any operations without any restrictions. The second level is the protection level. Under this level, the control system is in a state of security protection and can only be edited, saved, and copied. And other basic operations. The third level is the emergency protection level. At this level, the control system is equipped with an emergency stop switch. While saving the current file, it performs an emergency shutdown operation to prevent the system from crashing.
