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 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 attention.
Robot 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 devices.
In real life, you will find this a problem. In 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 injured. Think 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 it.
Production of mechanical hand can increase the automation level of production and labor productivity。 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 people. Here I would like to think of designing a robot to be used in actual production.
Why would a robot designed to provide a pneumatic power: pneumatic robot refers to the pressed air as power sourcedriven robot. With pressuredriven and other energydriven parison have the following advantages: 1. Air inexhaustible, used later discharged into the atmosphere, does not require recycling and disposal, do not pollute the environment. (Concept of environmental protection) 2. Air stick is small, the pipeline pressure loss is small (typically less than asphalt gas path pressure drop of onethousandth), to facilitate longdistance transport. 3. Compressed 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 lowered. 4. With the hydraulic transmission, pared to its faster action and reaction, which is one of the advantages pneumatic outstanding. 5. The air cleaner media, it will not degenerate, not easy to plug the pipeline. But there are also places where it fly in the ointment: 1. As 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 controlled. 2. As the use of low atmospheric pressure, the output power can not be too large。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 action. Action will have to use plex programmable robot controller, the microputer control.Three, mechanical hand classification and characteristics
Robots are generally divided into three categories: the first is the general machinery does not require manual hand. It is an independent not affiliated with a particular host device. It can be programmed according to the needs of the task to plete the operation of the provisions. It is characterized with ordinary mechanical performance, also has general machinery, memory, intelligence ternary machinery. The second category is the need to manually do it, called the operation of aircraft. It originated in the atom, military industry, first through the operation of machines to plete a particular job, and later developed to operate using radio signals to carry out detecting machines such as the Moon. Used in industrial manipulator also fall into this category. The third category is dedicated manipulator, the main subsidiary of the automatic machines or automatic lines, to solve the machine up and down the workpiece material and delivery. This mechanical hand in foreign countries known as the Mechanical Hand, which is the host of services, from the hostdriv
