【正文】 ees of freedom can be used to carry an object in order to plete the work in different wages in China, plastic products industry, although still a laborintensive, mechanical hand use has bee increasingly and automotive industries that Europe and the United States multinational panies very early in their factories in China, the introduction of automated now the changes are those found in industrialintensive South China, East China39。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 the rapid development of China39。s industrial production, especially the reform and opening up after the rapid increase in the degree of automation to achieve the workpiece handling, steering, transmission or operation of brazing, spray gun, wrenches and other tools for processing and assembly operations since, which has more and more attracted our is to imitate the manual part of the action, according to a given program, track and requirements for automatic capture, handling or operation of the automatic mechanical real life, you will find this a the machine shop, the processing of parts loading time is not annoying, and labor productivity is not high, the cost of production major, and sometimes manmade incidents will occur, resulting in processing were about what could replace it with the processing time of a tour as long as there are a few people, and can operate 24 hours saturated human right? The answer is yes, but the robot can e to replace of mechanical hand can increase the automation level of production and labor productivity。can reduce labor intensity, ensuringproduct quality, to achieve safe production。particularly in the hightemperature, high pressure, low temperature, low pressure, dust, explosive, toxic and radioactive gases such as poor environment can replace the normal working I would like to think of designing a robot to be used in actual would a robot designed to provide a pneumatic power: pneumatic robot refers to the pressed air as power sourcedriven pressuredriven and other energydriven parison have the following advantages: inexhaustible, used later discharged into the atmosphere, does not require recycling and disposal, do not pollute the environment.(Concept of environmental protection) stick is small, the pipeline pressure loss is small(typically less than asphalt gas path pressure drop of onethousandth), to facilitate longdistance air of the working pressure is low(usually 4 to 8 kg / per square centimeter), and therefore moving the material ponents and manufacturing accuracy requirements can be the hydraulic transmission, pared to its faster action and reaction, which is one of the advantages pneumatic air cleaner media, it will not degenerate, not easy to plug the there are also places where it fly in the ointment: the pressibility of air, resulting in poor aerodynamic stability of the work, resulting in the implementing agencies as the precision of the velocity and not easily the use of low atmospheric pressure, the output power can not be too large。in order to increase the output power is bound to the structure of the entire pneumatic system size 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 or asmall amount of leakage would not be a serious impact on of air is small, the pipeline pressure loss also is very small, easy longdistance lower working pressure of pressed air, pneumatic ponents and therefore the material and manufacturing accuracy requirements can be general, reciprocating thrust in 1 to 2 tons pneumatic economy is with the hydraulic transmission, and its faster action and reaction, which is one of the outstanding merits of air medium, it will not degenerate, not easy to plug the can be safely used in flammable, explosive and the dust big easy to realize automatic overload , the position, mechanical handRobot 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 agencies Manipulator executing agency by the hands, wrists, arms, are crawling institutions, is used to clamp and release the workpiece, and similar to human fingers, to plete the staffing of similar and fingers and the arm connecting the ponents can be up and down, left, and rotary simple mechanical hand can not used to support the arm can also be made mobile as The actuator to be achieved by the transmission system monly used manipulator mechanical transmission, hydraulic transmission, pneumatic and electric power transmission and other drive several System Manipulator control system39。s main role is to control the robot according to certain procedures, direction, position, speed of action, a simple mechanical hand is generally not set up a dedicated control system, using only trip switches, relays, control valves and circuits can be achieved dynamic drive system control, so that implementing agencies according to the requirements of will have to use plex programmable robot controller, the microputer , mechanical hand classification and characteristicsRobots are generally divided into three categories: the first is the general machinery does not require manual is an independent not affiliated with a particular host can be programmed according to the needs of the task to plete the operation of the is characterized with ordinary mechanical performance, also has general machinery, memory, intelligence ternary second category is the need to manually do it, called the operation of originated in the atom, military industry, first through th
