Industrial robot is an important branch of industrial robots. It features can be programmed to perfbn tasks in a variety of expectations, in both

2、 structure and performance advantages of their own people and machines, in particular, reflects the peoples intelligence and adaptability. The accuracy of robot operations and a variety of environments the ability to complete the work in the field of national economy and there are broad prospects fb

3、r 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 common in CNC machining processes material, usually still use manual or traditional relay-cont

4、rolled semi-automatic device. The former time-consuming 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, fault more maintenance problems and other issu

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 systems reliability, reduced maintenance rate, and improve work efficiency. Robot technology related t

Electronics and automotive industries that Europe and the United States multinational companies very early in their factories in China, the introduction of automated production. But now the changes are those found in industrial-intensive South China, East Chinas coastal a

10、 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, enches and other tools for processing and assembly operations since, which has more and more attracted

11、our attention. Robot is to imitate the manual part of the action, according to a given program, track and requirements fbr 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 tim

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 satu

13、rated 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 productivity; can reduce labor intensity, ensuring product quality, to achieve safe production; particularly in the high-temperature, hig

Here I would hke to think of designing a robot to be used in actual production.Why would a robot designed to provide a pneumatic power: pneumatic ro

15、bot refers to the compressed 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, does not require recycling and disposal, do not pollute the environment. (Concept of

16、environmental protection) 2. Air stick is small,the pipeline pressure loss is small (typically less than asphalt gas path 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 material components and manufacturing accuracy requirements can be lowered. 4. With the hydraulic transmission, compared to its faster action and reaction, wh
