Manipulator

Robot developed in recent decades as high-tech automated production equipment. Industrial rob

ot 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 mac

hines, in particular, reflects the people's intelligence and adaptability. The accuracy of robot operat

ions and a variety of environments the ability to complete the work in the field of national econom

y and there are broad prospects for development. With the development of industrial automation, t

here has been CNC machining center, it is in reducing labor intensity, while greatly improved labo

r productivity. However, the upper and lower common in CNC machining processes material, usua

lly still use manual or traditional relay-controlled semi-automatic device. The former time-consum

ing and labor intensive, inefficient; the latter due to design complexity, require more relays, wiring

complexity, vulnerability to body vibration interference, while the existence of poor reliability, fa

ult more maintenance problems and other issues. Programmable Logic Controller PLC-controlled

robot control system for materials up and down movement is simple, circuit design is reasonable,

with a strong anti-jamming capability, ensuring the system's reliability, reduced maintenance rate,

and improve work efficiency. Robot technology related to mechanics, mechanics, electrical hydrau

lic technology, automatic control technology, sensor technology and computer technology and oth

er fields of science, is a cross-disciplinary integrated technology.

First, an overview of industrial manipulator

Robot is a kind of positioning control can be automated and can be re-programmed to change in

multi-functional machine, which has multiple degrees of freedom can be used to carry an object i

n order to complete the work in different environments. Low wages in China, plastic products ind

ustry, although still a labor-intensive, mechanical hand use has become increasingly popular. Elect

ronics and automotive industries that Europe and the United States multinational companies very e

arly in their factories in China, the introduction of automated production. But now the changes are

those found in industrial-intensive South China, East China's coastal areas, local plastic processing

plants have also emerged in mechanical watches began to become increasingly interested in, beca

use they have to face a high turnover rate of workers, as well as for the workers to pay work-relate

d injuries fee challenges.

With the rapid development of China'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 asse

mbly operations since, which has more and more attracted our attention. Robot is to imitate the ma

nual 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 ti

me is not annoying, and labor productivity is not high, the cost of production major, and sometime

s man-made incidents will occur, resulting in processing were injured. Think about what could rep

lace it with the processing time of a tour as long as there are a few people, and can operate 24 hour

s saturated human right? The answer is yes, but the robot can come to replace it.

Production of mechanical hand can increase the automation level of production and labor produ

ctivity; can reduce labor intensity, ensuring product quality, to achieve safe production; particularl

y in the high-temperature, 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 l

ike 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 comp

ressed air as power source-driven robot. With pressure-driven and other energy-driven comparison

have the following advantages: 1. Air inexhaustible, used later discharged into the atmosphere, do

es not require recycling and disposal, do not pollute the environment. (Concept of environmental p

rotection) 2. Air stick is small, the pipeline pressure loss is small (typically less than asphalt gas pa

th pressure drop of one-thousandth), to facilitate long-distance transport. 3. Compressed air of the

working pressure is low (usually 4 to 8 kg / per square centimeter), and therefore moving the mate

rial components and manufacturing accuracy requirements can be lowered. 4. With the hydraulic t

ransmission, compared 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 ther

e are also places where it fly in the ointment: 1. As the compressibility of air, resulting in poor aer

odynamic stability of the work, resulting in the implementing agencies as the precision of the velo

city and not easily controlled. 2. As 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 increased.

With pneumatic drive and compare with other energy sources drive has the following advantage

s:

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 impa

ct on production. Viscosity of air is small, the pipeline pressure loss also is very small, easy long-d
