Research On Quality Monitoring And Fault Diagnosis System Of Automatic Production Line

With the development of industrial robots,CNC and electronic computer technology and the application of GT-group technology are making that the automatic production line is more and more flexible.It can be realized many varieties,small and medium volume production.At the same time,these field equipment were the most basic appliance in the modern manufacturing systems,the health running of them is the basic guarantee for the manufacturing enterprises.The fault diagnosis of equipment and quality monitoring of production process is more and more important because of equipment structure is becoming more and more complexible,and the manufacturing mode is becoming more and more integrated.With the essence of intelligent manufacturing,establishing a high degree of automation of the roller production line.Relying on the line within the seamless cooperation between Siemens numerical control machine tool and the detection technology,for processing unmanned factory.The rollers are manufactured.Through the fusion of sensors and PLC controller monitored quality of product and detected and analyzed the situation of the scene in the process of manufacture.It can adjust its status according to its needs and realize the adaptive control function.At the same time it can complete the coordination of multiple SIEMENS 840 D system.And the serial communication method was used to realize the transmission of large amounts of data.In order to provide the basis for the realization of FMS production line,it provided the coordination between the equipment and the channel through the M code.Secondly,this paper takes the fully automatic production line of roller as the object and combines with the research of artificial intelligence at the present stage.The fault diagnosis of the production line is designed by the method of fuzzy diagnosis technology based on feature knowledge.By using the SIEMENS Step 7 programming management software,WinCC configuration software and the Mamdani fuzzy diagnosis thought as the development tool,designing a fully automatic roller production line fault diagnosis system and achieving a good men-machine interface.It can test substandard products of the production line、display equipment fault alarm records and diagnose and analyze rapidly the fault of communication.At the same time,it also gives the failure phenomena,duration,the cause of failure and the measures to solve it.Production management personnel in the AlarmControl WinCC Control can easily obtain the alarm information through the alarm circuit function.It also can be able to file these alarm records and save them in the Sever SQL database.Therefore,the work efficiency and the production quality of the roller are greatly improved and the rejection rate is reduced,and reduces the maximize the loss of failure of the entire production.Eventually it makes the roller enterprises get the opportunity to life in the competitive market.
