附录附录 About Modenr Industrial Manipulayor Robot is a type of mechantronics equipment which synthesizes the last research achievement of engine and precision engine micro electronics and computer automation control and drive sensor and message dispose and artificial intelligence and so on With the development of economic and the demand for automation control robot technology is developed quickly and all types of the robots products are come into being The practicality use of robot not only solves the problems which are difficult to operate for human being but also advances the industrial automation program Modern industrial robots are true marvels of engineering A robot the size of a person can easily carry a load over one hundred pounds and move it very quickly with a repeatability of 0 006inches Furthermore these robots can do that 24hours a day for years on end with no failures whatsoever Though they are reprogrammable in many applications they are programmed once and then repeat that exact same task for years At present the research and development of robot involves several kinds of technology and the robot system configuration is so complex that the cost at large is high which to a certain extent limit the robot abroad use To development economic practicality and high reliability robot system will be value to robot social application and economy development With he rapid progress with the control economy and expanding of the modern cities the let of sewage is increasing quickly with the development of modern technology and the enhancement of consciousness about environment reserve more and more people realized the importance and urgent of sewage disposal Active bacteria method is an effective technique for sewage disposal The abundance requirement for lacunaris plastic makes it is a consequent for plastic producing with automation and high productivity Therefore it is very necessary to design a manipulator that can automatically fulfill the plastic holding With the analysis of the problems in the design of the plastic holding manipulator and synthesizing the robot research and development condition in recent years a economic scheme is concluded on the basis of the analysis of mechanical configuration transform system drive device and control system and guided by the idea of the characteristic and complex of mechanical configuration electronic software and hardware In this article the mechanical configuration combines the character of direction coordinate which can improve the stability and operation flexibility of the system The main function of the transmission mechanism is to transmit power to implement department and complete the necessary movement In this transmission structure the screw transmission mechanism transmits the rotary motion into linear motion Worm gear can give vary transmission ratio Both of the transmission mechanisms have a characteristic of compact structure The design of drive system often is limited by the environment condition and the factor of cost and technical lever The step motor can receive digital signal directly and has the ability to response outer environment immediately and has no accumulation error which often is used in driving system In this driving system open loop control system is composed of stepping motor which can satisfy the demand not only for control precision but also for the target of economic and practicality On this basis the analysis of stepping motor in power calculating and style selecting is also given The analysis of kinematics and dynamics for object holding manipulator is given in completing the design of mechanical structure and drive system Current industrial approaches to robot arm control treat each joint of the robot arm as a simple joint servomechanism The servomechanism approach models the varying dynamics of a manipulator inadequately because it neglects the motion and configuration of the whole arm mechanism These changes in the parameters of the controlled system sometimes are significant enough to render conventional feedback control strategies ineffective The result is reduced servo response speed and damping limiting the precision and speed of the end effecter and making it appropriate only for limited precision tasks Manipulators controlled in this manner move at slow speeds with unnecessary vibrations Any significant performance gain in this and other areas of robot arm control require the consideration of more efficient dynamic models sophisticated control approaches and the use of dedicated computer architectures and parallel processing techniques In the industrial production and other fields people often endangered by such factors as high temperature corrode poisonous gas and so forth at work which have increased labor intensity and even jeopardized the life sometimes The corresponding problems are solved since the robot arm comes out The arms can catch put and carry objects and its movements are flexible and diversified It applies to medium and small scale automated production in which production varieties can be switched And it is widely used on soft automatic line The robot arms are generally made by withstand high temperatures resist corrosion of materials to adapt to the harsh environment So they reduced the labor intensity of the workers significantly and raised work efficiency The robot arm is an important component of industrial robot and it can be called industrial robots on many occasions Industrial robot is set machinery electronics control computers sensors artificial intelligence and other advanced technologies in the integration of multidisciplinary important modern manufacturing equipment Widely using industrial robots not only can improve product quality and production but also is of great significance for physical security protection improvement of the environment for labor reducing labor intensity improvement of labor productivity raw material consumption savings and lowering production costs There are such mechanical components as ball footbridge slides air control mechanical hand and so on in the design A programmable controller a programming device stepping motors stepping motors drives direct current motors sensors switch power supply an electromagnetism valve and control desk are used in electrical connection Robot is the automated production of a kind used in the process of crawling and movin g piece features automatic device which is mechanized and automated production process d eveloped a new type of device In recent years as electronic technology especially compute r extensive use of robot development and production of hightech fields has become a rapidl y developed a new technology which further promoted the development of robot allowing robot to better achieved with the combination of mechanization and automation Robot can replace humans completed the risk of duplication of boring work to reduce human labor int ensity and improve labor productivity Manipulator has been applied more and more widely in the machinery industry it can be used for parts assembly work piece handling loading a nd unloading particularly in the automation of CNC machine tools modular machine tools more commonly used At present the robot has developed into a FMS flexible manufacturin g systems and flexible manufacturing cell in an important component of the FMC The mac hine tool equipment and machinery in hand together constitute a flexible manufacturing syst em or a flexible manufacturing cell it was adapted to small and medium volume production you can save a huge amount of the work piece conveyor device compact and adaptable W hen the work piece changes flexible production system is very easy to change will help ent erprises to continuously update the marketable variety improve product quality and better adapt to market competition At present China s industrial robot technology and its enginee ring application level and comparable to foreign countries there is a certain distance applica tion and industrialization of the size of the low level of robot research and development of a direct impact on raising the level of automation in China from the economy technical cons iderations are very necessary Therefore the study of mechanical hand design is very meani ngful
