Abstract: In order to improve the assembly efficiency of the oxygen sensor protective cover and pedestal,and to ensure the reliability of equipment operation,the assembly machine and its control system for oxygen sensor protective cover-pedestal were designed.The whole scheme and working principle of the assembly machine were analyzed in detail,the key parts of the system were designed,including the pushing mechanism and the assembling mechanism.The hardware structure of the control system was introduced,including the main control unit,the system driver module,sensing module and the touch screen.The software part of the control system was described concretely,the control flow of PLC was elaborated,GT-Designer3 was used to design the operation interface of the system to realize human-computer interaction.The equipment has been put into use,and actual operation results show that the assembly machine is stable in performance,the assembly efficiency is improved by 25.3 %,and the assembly yield rate reaches as high as 99.96 %,which meets the production requirements.

Key words: oxygen sensor, assembly machine, control system, PLC
