2 2 dramatically Japan was labor significant deficiencies in enterprise industrial robots by savior s welcome make its Japanese industrial robots get fast development the number of now whether robots or robot densities are top of the world known as the robot kingdom said The robot introduced from Germany time than Britain and Sweden about late 1956 but the Labour shortages caused by war national technical level is higher social environment but for the development and application of industrial robot provides favorable conditions In addition in Germany for some dangerous prescribed poisonous or harmful jobs robot instead of ordinary people to the labor This is the use of robots exploit a wide range of markets and promote the development of the industrial robot technology At present the German industrial robots total of the world which only behind to Japan The French government has been more important robot technology and through a series of research program support established a complete science and technology system make the development of the French robot smoothly In government organization project pay special attention to the robot research based technique the focus is on the application research on in robot And by industry support the development application and development of work both supplement each other make robots in France enterprises develop rapidly and popularize and make France in the international industrial machine with indispensable if position British jam since the late 1970s promote and implement a department measures listed support the development of policies and make robots British industrial robots than today s robot powers started to early and once in Japan has made the early brilliance However at this time the government for industrial robots implemented the constraining errors This mistake in Britain dust the robot industry in Western Europe was almost in the bottom of it In recent years Italy Sweden Spain Finland Denmark and other countries because of its own domestic robots market in great demand development at a very fast pace At present the international on industrial robot company mainly divided into Japanese and European series In AnChuan of Japanese are mainly the ethical products the oTC panasonic FANLUC not two more etc The products of the company kawasaki The main Asiatic KUKA German CLOOS Sweden s ABB Italy CO work pelatiah U and Austria GM company Industrial robot in China started in early 1970s after 30 years development roughly experienced three stages in the 1970s and 1980s budding transplanter and the application of the 1990s initialization period With the 20th century 70 s world 滨州学院本科毕业论文 外文翻译 3 3 technology rapid development the application of industrial robots in world created a climax in this context our country in 1972 start developing their industrial robots Enter after the 1980s with the further reform and opening in high technology waves pound our research and development of robot technology from the government s attention and support during the seventh state funds thanked the parts were set robot and research completed demonstration emersion type

robots enterprise holds Before the gunman in the international domestic industrial robots enterprise facing great pressure of competition Now China is from a manufacturing power to manufacturing power forward Chinese manufacturing industry faces and the international community participate in the international division of labor in the great challenge of industrial automation increase immediate government must can increase the funds for robots and policy support will give the industry of industrial robots development into new momentum With independent brand devil robot MoShi special technology company dedicated to providing solutions to the mainboard and robot is willing with all my colleagues a build domestic industrial robot happy tomorrow The industrial robot is used in the manufacturing environment to increase productivity It can be used to do routine and tedious assembly line jobs or it can perform jobs that might be hazardous to do routine and tedious assembly line jobs or it can perform jobs that might be hazardous to the human worker For example one of the first industrial robots was used to replace the nuclear fuel rods in nuclear power plants A human doing this job might be exposed to harmful amounts of 滨州学院本科毕业论文 外文翻译 5 5 radiation The industrial robot can also operate on the assembly line putting together small components such as placing electronic components on a printed circuit board Thus the human worker can be relieved of the routine operation of this tedious task Robots can also be programmed to defuse bombs to serve the handicapped and to perform functions in numerous applications in our society The robot can be thought of as a machine that will move an end of arm tool sensor and gripper to a preprogrammed location When the robot arrives at this location it will perform some sort of task This task could be welding sealing machine loading machine unloading or a host of assembly jobs Generally this work can be accomplished without the involvement of a human being except for programming and for turning the system on and off The basic terminology of robotic systems is introduced in the following 1 A robot is a reprogrammable multifunctional manipulator designed to move parts materials tools or special devices through variable programmed motions for the performance of a variety of different task This basic definition leads to other definitions presented in the following paragraphs that give a complete picture of a robotic system 2 Preprogrammed locations are paths that the robot must follow to accomplish work At some of these locations the robot will stop and perform some operation such as assembly of parts spray painting or welding These preprogrammed locations are stored in the robot s memory and are recalled later for continuous operation Furthermore these preprogrammed locations as well as other program data can be changed later as the work requirements change Thus with regard to this programming feature an industrial robot is very much like a computer where data can be stored and later recalled and edited 3 The manipulator is the arm of the robot It allows the robot to bend reach and twist This movement is provided by the manipulator s axes also called the degrees of freedom of the robot A robot can have from 3 to 16 axes The term degrees of freedom of freedom will always relate to the number of axes found on a robot 4 The tooling and grippers are not part of the robotic system itself rather they are attachments that fit on the end of the robot s arm These attachments connected to the end of the robot s arm allow the robot to lift parts spot weld paint arc weld drill deburr and do a variety of tasks depending on what is required of the robot 滨州学院本科毕业论文 外文翻译 6 6 5 The robotic system can also control the work cell of the operating robot the work cell of the robot is the total environment in which the robot must perform its task Included within this cell may be the controller the robot manipulator a work table safety features or a conveyor All the equipment that is required in order for the robot to do its job is included in the work cell In addition signals from outside devices can communicate with the robot in order to tell the robot when it should assemble parts pick up parts or unload parts to a conveyor The robotic system has three basic components the manipulator the controller and the power source A Manipulator The manipulator which does the physical work of the robotic system consists of two sections the mechanical section and the attached appendage The manipulator also has a base to which the appendages are attached Fig 1 illustrates the connection of the base and the appendage of a robot The base of the manipulator is usually fixed to the floor of the work area Sometimes though the base may be movable In this case the base is attached to either a rail or a track allowing the manipulator to be moved from one location to another As mentioned previously the appendage extends from the base of the robot The appendage is the arm of the robot It can be either a straight movable arm or a jointed arm the jointed arm is also known as an articulated arm The appendages of the robot manipulator give the manipulator its various axes of motion These axes are attached to a fixed base which in turn is secured to a mounting This mounting ensures that the manipulator will remain in one location At the end of the arm a wrist is connected The wrist is made up of additional axes and a wrist flange The wrist flange allows the robot user to connect different tooling to the wrist for different jobs The manipulator s axes allow it to perform work within a certain area This area is called the work cell of the robot and its size corresponds to the size of the manipulator Fig 2 illustrates the work cell of a typical assembly robot As the robot s physical size increases the size of the work cell must also increase The movement of the manipulator is controlled by actuators or drive systems The actuators or drive system allows the various axes to move within the work cell The drive system can use electric hydraulic or pneumatic power The energy 滨州学院本科毕业论文 外文翻译 7 7 developed by the drive system is converted to mechanical power by various mechanical drive systems The drive systems are coupled through mechanical linkages These linkages in turn drive the different axes of the robot The mechanical linkages may be composed of chains gears and ball screws B Controller The controller in the robotic system is the heart of the operation The controller stores preprogrammed information for later recall control peripheral devices and communicates with computers within the plant for constant updates in production The controllers is used to control the robot manipulator s movements as well as to control peripheral components within the work cell The user can program the movements of the manipulator into the controller through the use of a hand held teach pendent This information is stored in the memory of the controller for later recall The controller stores all program data of the robotic system It can store several different programs and any of these programs can be edited The controller is also required to communicate with peripheral equipment within the work cell For example the controller has an input line that identifies when a machining operation is completed When the machine cycle is completed the input line turns on telling the controller to position the manipulator so that it can pick up the finished part Then a new part is picked up by the manipulator and placed into the machine Next the controller signals the machine to start operation The controller can be made from mechanically operated drums that step through a sequence of events This type of controller operates with a very simple robotic system The controllers found on the majority of robotic systems are more complex devices and represent state of the art electronics That is they are microprocessor operated These microprocessors are either 8 bit 16 bit or 32 bit processors This power allows the controller to be very flexible in its operation The controller can send electric signals over communication lines that allow it to talk with the various axes of manipulator This two way communication between the robot manipulator and the controller maintains a constant update of the location and the operation of the system The controller also controls any tooling placed on the end of the robot s wrist The controller also has the j
