The design and process of research of identifier,coordinating with the X-ray detecting mechanism,acted as to indicating the unqualified tires in the large numbered tire automatic production line and the finally determined mechanical structure and controlling principle were narrated.

It can be used for teaching and training in the field of mechanical and electrical engineering, which provide the base for instruction of automatic production line and mechano-eletronics.

A novel type automatic production line for casting austempered ductile iron grinding balls with the metal mould was introduced, including equipment and processes.

The principle and application of synchronous velocity control in automatic product line;

This paper summarizes the methods of state monitoring and fault diagnosis in automatic product line nowadays, analyses the application of machine vision in this area, and finally predicts the prospect of this application.

A new developed tread taking out unit for tire tread extrusion line, it can take out thequalified tread from the tread production line onto the pointed position of the book layer automatically,which solved the quality problem of manual operation and eased the labour strength of workers.
