Description

Technical Field

[0001] This application relates to the field of electromechanical equipment technology, and more specifically, to an integrated I / O device and a laser cutting machine. Background Technology

[0002] Laser cutting utilizes a high-power-density laser beam to irradiate the material being cut, rapidly heating it to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves across the material, the holes continuously form a narrow kerf, completing the cutting process. Current metal processing lasers primarily use I / O ports for communication. With increasing laser power and machine tool size, the number of I / O signals required by the bus-based CNC system increases significantly. Traditional I / O modules are categorized by function, with each module having only a few I / O points for a single function. Therefore, the number of I / O modules that need to be connected increases. This not only increases costs but also makes wiring more complex with more I / O modules. Utility Model Content
