Automatic fiber laser cutting machine intelligent high power focusing fiber cutting head
A high-power focusing fiber cutting head for intelligent automatic fiber laser cutting machine. It can be adapted to optical fiber interfaces such as Qplus/QD. The higher power 15kW+ PoLeader will usher in a new era of laser cutting. The newly designed cutting head gas path can not only achieve high-quality and faster cutting, improve cutting efficiency, but also monitor the internal conditions of the cutting head in real time and increase the life of the lens. . Fiber laser cutting machine is a mature product that Han's Laser pioneered in China and reached the international leading level. This series of products is a model for the metal material processing industry, with powerful cutting ability, 'flying' cutting speed, extremely low operating cost, excellent stability, high-quality processing and strong adaptability.
The motion control function of the fully automatic fiber laser cutting machine is realized by PMAC executing online instructions and motion control programs. The online instructions can only perform simple motion control, such as returning to the origin. . The motion control program can do some complex motion control, such as circular motion, sine motion and so on. There are two ways to execute online instructions and motion control programs: install the execution software PEWin32 provided by the PMAC manufacturer, and then establish the connection between the industrial control machine and the motion control card through the corresponding communication interface, and then you can use the software command The window sends online instructions and motion control programs; second, it is realized through software programming. The PCI bus establishes the communication link between the industrial control machine and the multi-axis motion controller, and sends online instructions or downloads the motion control program to the motion control card. When writing a motion control program, first define the coordinate system and the motor under the coordinate system to establish the matching relationship between the two; secondly, write the program according to the prescribed grammatical rules, and select the corresponding instructions and parameters according to the required motion requirements. , And finally download the prepared program to PMAC. The upper and lower computer communication module design adopts the powerful external program interface (Active X automation technology) provided by the upper computer programming software LabVIEW to call the server program PcommServer provided by PMAC. The underlying server PcommServer provides many functions that interact with PMAC. In the design, functions such as initializing the board, opening the board, closing the board, sending commands, and downloading motion programs are mainly used. Initialize the board to complete the registration of the PMAC in the host computer, and open the board to enable the communication module. If the board is opened successfully, the server can send instructions to PMAC, receive PMAC return information, or download exercise programs to PMAC. When the board fails to open, the system will return a failure to open the device information. The communication method between the industrial control machine and the motion control board is actually realized through the client calling the server city: LabVIEW is used as the automation client, and the function provided by the motion control card is used as the automation server.
The automatic fiber laser cutting machine uses industrial control machine and multi-axis motion control card as the main hardware of the system, LabVIEW as the upper computer software development platform, and uses LabVIEW graphical programming language The ease of operation and the ability to call Active X and other functions to achieve the secondary development of PMAC, make full use of the industrial control machine's strong information processing capability and the characteristics of fast motion control card operation control speed, complete the laser cutting machine control system design. It has been verified that the control system has the characteristics of strong scalability, high openness, short development cycle and easy operation.
