Research On Principle And Fault Diagnosis Of Simulating Teaching Flexible Production Line In Laboratory

The flexible production line is a kind mixture system with auto line and the flexible manufacturing characteristic, the production system is composed of high speed manufacturing centers with compensating and displacing each other by making fixed direction transferring units in the system. Because of adopting fixed direction transferring material flow, the system for transferring material is simpler. Rolling transfer ration is adopted the transferring system has the function of storing. So utilization is increased. The flexible production line can be divided randomly, products can be produced.The simulating teaching flexible production principle and defaults diagnosis are researched in the paper. The function and principle are illustrated in detail. The method for defaults diagnosis is simply explained. The diagnosis system structure of intelligent diagnosis, the method of intelligent diagnosis, the principle of defects, the model of defects, the technology and development of the integrated system are importantly researched.In the flexible production line, divided and concentrated control are adopted, siemens PLC control is adopted in divided control system, touching screen control is adopted in concentrated control system. The whole production line adopted laser electricity and atmosphere pressure, including all production lines. The students can master the constitution, characters, working principle and control. The wiring is known perfectly. Therefore it is improved with the development of factories.It will put forward the some advanced teaching the thought and the actual operation methods, also increase the students' ability in operating each units. Inquiring into linear principle in gentle production, directly knowing that student to the gentle production line unit constituting and each parts of functions. Benefit toControl the maintenance in maintaining for the students, fault points can be detected. The better function is developed on the original base further to increase the other units.The following units are mainly researched: transferring linearly and rotatingly, simulating spraying, adding cover, top wedge, detection wholly, dividing waste products, transferring waste products, storeroom in the high shelves, the whole control platform etc, twelve items.
