Feeding System Of Screen Printing Machine Based On Six-axis Robot And Machine Vision

With the development of industry,intelligent production is the only way of industrial development.Automatic loading and unloading system is an important part of intelligent production.It is of great significance to solve the problem of automatic loading and unloading for pen holder silk screen printing.The application of PLC,visual inspection and six axis robot in the automatic production process is more and more widely,which is one of the hot spots in the automation industry and one of the key technologies in the design of modern intelligent production equipment.With the help of these technologies,according to the needs of users,in-depth study of the pen holder silk screen loading and unloading system,design a stable and reliable,human-computer interaction friendly intelligent device is a very meaningful work.After analyzing the production process and equipment operation mode of silk screen printing,this paper designs a complete set of automatic production system,which uses Delta PLC and touch screen as the main control system,visual inspection and six axis robot as the auxiliary handling system.The system integrates the advantages of PLC control system,six axis robot and visual processing technology to make it stable and flexible.In the system,PLC is used as the core controller to control the operation of the whole system,industrial computer and visual inspection software are used as visual processing equipment,six axis robot,three-phase motor and cylinder are used to perform specific production actions.The functions of vision software include error detection and pallet material detection.The error detection is realized by opencv library function,and the material detection is completed by a small convolutional neural network.Delta PLC program is written and debugged on its special software wplsoft,and the program language is ladder diagram language.The design of human-computer interface is completed on dopsoft,including variable connection,communication setting and screen design.The visual inspection software is written and debugged in Python,including UI design,process planning and program writing.For the six axis robot,the path planning technology is used to simulate its operation in advance to ensure the correctness of its selection and application.The design in this paper has been debugged and run in the actual project,the system design is reasonable and reliable,the human-computer interaction is friendly,the production efficiency meets the design requirements,and has been tested by the actual production,which has the promotion value.
