The Design Of Automatic Control System For Glass Edging Based On Robot And PLC

In recent years,with the rapid development of electronic computer technology,industrial robots are more and more widely used in the automation control of electrical equipment.PLC,as the core of the automatic control field,plays an increasingly important role in the intelligent manufacturing field.In the existing glass processing,glass edging is an essential process,and there are certain requirements for processing accuracy.At present,the domestic factories usually use the three-axis machining center CNC to grind the glass edge.This processing method is replaced by machine production and manual production,which can greatly improve the production efficiency and quality of glass edge grinding,and can liberate the labor force.However,this production mode can not be fully automated,because although CNC has replaced manual edge grinding,the manual chip loading and unloading is still the main processing mode of glass factory at present,which is not only inefficient,but also extremely labor-intensive.In this project,the industrial robot and pneumatic control system are used to carry the glass,the pneumatic control system is used to precisely position and clamp the glass,the PLC and servo motor are used to precisely control the position of the industrial robot,and the HMI is used as the human-computer interaction of the system,so as to create a highly integrated,comprehensive and stable automatic control system.The six axis industrial robot,with high degree of freedom,stable operation,high positioning accuracy,can quickly and efficiently complete the extraction and placement of glass,and has high precision.Combined with the precise positioning of pneumatic control,it can meet the grinding precision of glass and improve the processing quality of products.The selection of PLC is to control the servo motion.By using the high-speed pulse output function and the high-speed counter function of PLC,the servo motor can be controlled,so as to achieve the precise positioning of industrial robot.Moreover,PLC can also place some important processing parameters on HMI through RS485 communication,so as to achieve the purpose of human-computer interaction,greatly improving the whole set of equipment Man machine interaction of the equipment.The robot gripper design,positioning system design and robot running guide base design completed in this project are all original and innovative designs for the Intelligent Research Institute of edge grinding technology;the circuit system design and pneumatic control system design in this study are original designs for the system level and controllevel of the automatic control system,which provide the theory for the same type of intelligent project design On the knowledge of research results and engineering design reference.In addition,in the aspect of robot vision,a four-point photoelectric detection method is proposed to solve the problem of the position deviation of the robot’s grasp glass,which plays an ideal role in the actual operation.This theory and method provides a simple and cost-effective alternative for machine vision in intelligent design.Through the actual operation in the factory,the whole automatic control system shows enough stability and advantages compared with the manual operation,its positioning accuracy can fully meet the processing requirements of glass edging,its working efficiency is greatly improved compared with the manual operation.The integrated automatic control system makes glass production more unmanned and intelligent.
