Clean air medium, it will not degenerate, not easy to plug the pipeline. It can be safely used in flammable, explosive and the dust big occasions. Also easy to realize automatic overload protection. Second, the position, mechanical hand Robot in the form of a variety of forms, some relatively simple, some more plicated, but the basic form is the same as the position of the , Usually by the implementing agencies, transmission systems, control systems and auxiliary devices posed. 1. Implementing agencies Manipulator executing agency by the hands, wrists, arms, pillars. Hands are crawling institutions, is used to clamp and release the workpiece, and similar to human fingers, to plete the staffing of similar actions. Wrist and fingers and the arm connecting the ponents can be up and down, left, and rotary movement. A simple mechanical hand can not wrist. Pillars used to support the arm can also be made mobile as needed. 2. Transmission The actuator to be achieved by the transmission system. Subtransmission system monly used manipulator mechanical transmission, hydraulic transmission, pneumatic and electric power transmission and other drive several forms. 3. Control System Manipulator control system39。 can reduce labor intensity, ensuring product quality, to achieve safe production。s coastal areas, local plastic processing plants have also emerged in mechanical watches began to bee increasingly interested in, because they have to face a high turnover rate of workers, as well as for the workers to pay workrelated injuries fee challenges. With the rapid development of China39。 the latter due to design plexity, require more relays, wiring plexity, vulnerability to body vibration interference, while the existence of poor reliability, fault more maintenance problems and other issues. Programmable Logic Controller PLCcontrolled robot control system for materials up and down movement is simple, circuit design is reasonable, with a strong antijamming capability, ensuring the system39。外文出處：《 Manufacturing Engineering and Technology— Machining》 附件 1：外文原文 Manipulator Robot developed in recent decades as hightech automated production equipment. Industrial robot is an important branch of industrial robots. It features can be programmed to perform tasks in a variety of expectations, in both structure and performance advantages of their own people and machines, in particular, reflects the people39。s intelligence and adaptability. The accuracy of robot operations and a variety of environments the ability to plete the work in the field of national economy and there are broad prospects for development. With the development of industrial automation, there has been CNC machining center, it is in reducing labor intensity, while greatly improved labor productivity. However, the upper and lower mon in CNC machining processes material, usually still use manual or traditional relaycontrolled semiautomatic device. The former timeconsuming and labor intensive, inefficient。s reliability, reduced maintenance rate, and improve work efficiency. Robot technology related to mechanics, mechanics, electrical hydraulic technology, automatic control technology, sensor technology and puter technology and other fields of science, is a crossdisciplinary integrated technology. First, an overview of industrial manipulator Robot is a kind of positioning control can be automated and can be reprogrammed to change in multifunctional machine, which has multiple degrees of freedom can be used to carry an object in order to plete the work in different environments. Low wages in China, plastic products industry, although still a laborintensive, mechanical hand use has bee increasingly popular. Electronics and automotive industries that Europe and the United States multinational panies very early in their factories in China, the introduction of automated production. But now the changes are those found in industrialintensive South China, East China39。s industrial production, especially the reform and opening up after the rapid increase in the degree of automation to achieve the workp
