Gearbox sliding bracket is an important component of Automobile Gearbox. Because it has many parts which have little difference in shape and size, it is very easy to make mistake in assembly parts of this component. Due to mass production, it is high time to develop an online inspection system for the aseembly quality. Analysis the assembly characteristic of the component, this paper develop an online inspection system which is mainly composed of a central control system(CCS) and a sensor. Under the command of the CCS, the sensor is able to automatically inspect the component’s parts of which are wrong assmbly, reverse assembly and missing assmbly. Also the sensor can send the inspection information to the CCS. Subsequently, the CCS judges the information and dispalys the judgment result in time. At the same time, through the network, it is able to send the assembly quality information to the enterprise quality management system, such as the eligible amount, the reject amount, the qualification rate. This online automatic inspection system has run in good condition since it was officially put into operation at 2007 and its accuracy comes up to 100%.
