It is a new technology appearing in modern automatic controlled field, and has already become an important component in the production system of modern machine-building. It is one kind according to certain procedure , the mechanical device that can be carried and operated automatically, and the part that can replace people works, have some functions of people's, and there are not some manually operated weaknesses . The industry manipulator is generally divided into three kinds. The first kind does not need the manually operated manipulator in common use . The second kind needs to be manually operated, is called the operating machine. The third kind is a special-purpose manipulator, affiliate on the automatic lathe or the transfer machine mainly, used to solve the upper and lower material of lathe and work piece to convey. This kind of manipulator is called " Mechanical Hand " abroad, the working routine is generally regular, so it is special-purpose. The industry manipulator belongs to this kind of too, the industry manipulator has been developed quickly in recent years. This graduation project is used in the polishing to the sewing machine needle , use the swing manipulator on the polishing transfer machine, this conveyance equipment comes to replace artificial work. In the mechanical manufacturing industry abroad, the industry The industry manipulator is used more, it is very fast to develop. Present manipulator all have a certain sensing ability , the sense of touch function is to install and feedback the control device on hand in machinery . The mainer one is combining flexible manufacturing system and flexible manufacturing unit with the manipulator, artificial operation state of the manufacture system that can be essentially mechanical. By the look of economy, the industry manipulator can boost productivity , guarantee product quality, reduce the rejection rate , the loaded ability to raise basic device ; By the look of technology, the use of the operating machine has related to the fact that it is small product quality and automation increasing are produced while producing in batches. The automatic degree is the highest in large-scale production, but take second place in the small automatic degree while producing in batches. In sum , use the manipulator effectively, it is the inexorable trend which develops mechanical industry.
