Assemble and disassemble control technology for ladle long nozzle based on visual guidance and industrial robot drive
To solve the problems of high labor intensity,high safety risks,low accuracy and efficiency of manual installation and disassembly of ladle nozzles in high temperature and high noise environments during continuous casting,a control scheme for the installation and disassembly of ladle long nozzles was designed using 3D high-precision visual guidance technology as the detection system,PLC equipment as the control platform,and six axis industrial robots as flexible driving sources.This scheme uses Ethernet communication to transmit the position information detected by the visual system to the robot system through PLC control,and drives the robot to complete the automated action process according to the process requirements,which achieves precise and intelligent control of the loading and unloading process of the ladle long nozzle.The test results proved that this technology achieves a total installation or disassembly time of≤80 s from the robot taking the fixture to putting it back,with hit rate of>99%,meeting the process requirements and indicators.This system this system not only frees operators from heavy physical labor and harsh working environments,but also improves the accuracy and stability of loading and unloading nozzles,greatly improves production efficiency and ensures the quality of the casting billet.
