Microcomponent Thickness Comprehensive Detecting Plain Test Control System Designing Zhenwei Duan Yanhua Li Denren Kong Chang’an Di Department of precision instrument of School of Mechanical Engineering in NUST, Nanjing, 210094 Phone (086) 025 E-Mail: willendzw@163.com Abstract: This article introduces the overall plan of the testing controlling system of the platform for testing the thickness of the microcomponent, the working principle and the design method. It introduces the driving system, controlled by the PLC programmed controlling step-motor, to accomplish the testing of microcomponent in the form of production chain. It introduces the communication and control method between the thickness-testing sensor and PC. It discusses how can the PLC controlling microcomponent material distribution machine accomplishes distribution task, when getting sort signals form PC. It discusses the realization method, in which all kind of status in operating process can be tested and the fault can be tolerated. This system was debugged in industrial location and its feasibility was proved well. keywords: microcomponent， detecting，classification automatization， Manipulate Microcomponent is a critical unit in air condition and air compressor, whose geometry dimension, surface roughness, margin tolerance etc deeply effects the refrigeration and calefaction of them. Actually as the demand of air condition and air compressor are more and more vast, the demand of microcomponent is more and more vast too and the degree of accuracy of microcomponent is more and more higher. Now after the microcomponent was machininged and producted, which was mainly detected manually, the verification became where the shoe pinches. The traditional verification method has the problem of slow velocity, low efficiency and man induced factor effect. So we developed this Microcomponent Thickness Comprehensive Detecting Plain. The Programmable Logic Controller of S7-200 catena, which is made
