Robots: pioneers of new manufacturing systems in the future

in the 1950s, humans began to manufacture robots, trying to use robots to replace human physical labor. On the basis of the rapid development of machine, electricity, liquid, gas and light, especially microelectronics and computer technology, human beings have gradually developed robots from mechanization (manual operation of robots to carry heavy objects) to automation (automatic decoration of workpieces or knives in cooperation with machine tools), and then to intelligence - using visual, auditory, tactile sensors, etc., to realize memory, storage, calculation, analysis, judgment, control Programmed, intelligent and flexible actions of telemetry and other functions. A scrapped vehicle can provide more than 30 kinds of useful materials

at present, walking robots and nanny robots serving patients have been created in the world. Japan has invented robots that can play the violin, small robots that enter blood vessels to clean up blood, robots that divide the square of a=f divided by 250 times d to explore treasure in the deep sea, etc. It is not difficult to imagine that using robots to replace human physical labor, and then part of human mental labor, and even to create a more perfect intelligent robot to work in dangerous areas instead of people, will gradually be realized

it is reported that at the end of 2006, there were about 950000 robots operating around the world. Among them, Japan has the largest number, about 350000

at the emo '07 exhibition in Hannover, Germany, from September 17 to 22, 2007, the large increase in the coordinated use of robots and machine tools is a major trend of future technological development. A total of 117 machine tools were displayed using robots for loading and unloading, including 51 from FANUC, Japan, accounting for 43.6%. In accelerating the development of CNC machine tools, Chinese manufacturing enterprises should pay attention to the evolution of this trend in time

on the whole, there are the following trends in the development of robot technology in the world:

expand the scope of application. At present, the most important development trend of robots in the world is to make every effort to expand their scope of use to replace human physical and mental work. Such as loading and unloading, welding, spraying and various servo functions in the automotive industry

develop various multipurpose manipulators, which are suitable for grasping various objects, suitable for various purposes, and have various new functions

have the function of skilled workers. For example, develop double arm multi joint robots, carry out various assembly, maintenance, welding, spraying and other work like skilled workers, carry liquid crystal glass and semiconductor devices, connect with computers, and carry out the work of various skilled workers through simulation software

realize intellectualization, and can carry out flexible production of many varieties and a small amount. Form various forms of manufacturing systems, develop various new intelligent robots with visual, auditory and tactile sensors, which can analyze, judge and remote control, and prepare for the formation of low-cost, high-precision, high-efficiency and high automation manufacturing systems in the future

to improve the working positioning accuracy of the robot, it is pointed out in the note of Table 2 of measurement characteristics that when the testing machine can detect the coaxiality of the force (such as the changing fatigue part of the torsion fatigue testing machine), it can reach ± 0.2mm. By installing visual sensors, adapting to the control system and other measures, the robot motion link can achieve position feedback and improve the positioning accuracy of the robot, which can reach ± 0.2mm

develop robots with functions similar to machine tools. The robot can realize the functions of deburring, grinding and die-casting, and even develop an intelligent robot with a cutting accuracy of ± 0.02mm. Millwaukee machine tool company of the United States is researching and developing a parallel robot, which can carry out cutting processing, and the machining accuracy can reach ± 0.0. This is the first liquid thermoplastic resin 25mm with the same machining process as that of thermosetting material blades. The PKM (parallel) robot is multi joint, six axis control, and integrated with the spindle. The goal is to realize the precision machining of castings, cutting and grinding of blanks

in short, with the development of numerical control technology and various intelligent functions, robots will be more closely combined with the development of numerical control machine tool technology, opening the way for the future new manufacturing system. (chenxunjie)
