【正文】 s 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。 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。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。 can reduce labor intensity, ensuring product quality, to achieve safe production。 in order to increase the output power is bound to the structure of the entire pneumatic system size increased. With pneumatic drive and pare with other energy sources drive has the following advantages: Air inexhaustible, used later discharged into the atmosphere, without recycling and disposal, do not pollute the environment. Accidental or a small amount of leakage would not be a serious impact on production. Viscosity of air is small, the pipeline pressure loss also is very small, easy longdistance transport. The lower working pressure of pressed air, pneumatic ponents and therefore the material and manufacturing accuracy requirements can be lowered. In general, reciprocating thrust in 1 to 2 tons pneumatic economy is better. Compared with the hydraulic transmission, and its faster action and reaction, which is one of the outstanding merits of pneumatic. 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。 exception of a few outside the working procedures are generally fixed, and therefore special. Main features: First, mechanical hand (the upper and lower material robot, assembly robot, handling robot, stacking robot, help robot, vacuum handling machines, vacuum suction crane, laborsaving spreader, pneumatic balancer, etc.). Second, cantilever cranes (cantilever crane, electric chain hoist crane, air balance the hanging, etc.) Third, railtype transport system (hanging rail, light rail, single girder cranes, doublebeam crane) Four, industrial machinery, application of hand Manipulator in the mechanization and automation of the production process developed a new type of device. In recent years, as electronic technology, especially puter extensive use of robot development and production of hightech fields has bee a rapidly developed a new technology, which further promoted the development of robot, allowing robot to better achieved with the bination of mechanization and automation. Although the robot is not as flexible as st
