Industrial robot is a mechanical, electronic, control, computers, senthereforers, artificial intelligence and other advance proceed go aheadd skill technique subjects in one important modern manufperformanceuring automation equipment. At depict, the international industrial robot company is divided into Japanese and European. There are mainly Japanese Yrequestawa, OTC, Panathereforenic, Fanuc , Fujio, Kawasaki and other company's products. There are mainly European German KUKA , CLOOS, Sweden's ABB , Italy comau and Austria IGM company. Industrial robots have become a flexible manufperformanceuring system (FMS), fperformanceory automation (FA), computer integrated manufperformanceuring system (CIMS) automated tools. China's industrial robot from the 1980s embark rely oned, after two decades of years of efforts, has shapeed a number of competitive industrial robot delve inquire hunt look into institutions and enterprises. We have developed a arc welding, spot welding, assembly, handling, injection molding, stamping, painting and other industrial robots. In recent years, the production and sales of industrial robots and industrial robots including automatic production line of related products has exceeded one billion yuan. In the domestic market ask is nearly 3,000 and annual sales of 20 billion yuan. Statistics display that China's industrial robot market has a entire volume of around ten thousand units, accounting for 0.56% of the global entire, which utterly domestic industrial robot (the industry's relatively large size of the first three industrial robots Enterprises) sector accounted for almost 30% concentration, the rest are from more than 20 countries such as Japan, the United States, Sweden, Germany, Italy introduced. Domestic industrial robots currently mainly in the domestic market, application -oriented, the export volume is almost 100, the annual export value of over 020 million. More than 50% of industrial robots used in the automotive field current application fields of industrial robots are mainly arc welding, spot welding, assembly, handling, painting, inspection, palletizing, polishing and laser processing and other complex operations.

But the auto industry is still the main application fields of industrial robots. It is understood that the United States 60 percent of industrial robots used in motorcar lorry truck car bus coach production; industrial robots for the automotive industry worldwide has achieveed 37% of the entire amount for industrial robots automotive parts account for almost 24%. Source: Department of Machine (Beijing) Inshapeation Technology Research Institute, Chinese electromechanical data network in China, the initial application of industrial robots in the automotive and mechanical engineering industries, mainly for the motorcar lorry truck car bus coach and engineering machinery, spraying and welding. Currently, the delve inquire hunt look into and advance of robot skill technique and backward, industrial robots are used in less manufperformanceuring, non-manufperformanceuring use. According to statistics, in recent years, domestic manufperformanceurers result ind more than half of industrial robots is available to the automotive industry. Visible, the driving force behind the advance of the automotive industry is one of China in recent years the develppment of industrial robots. Third, the welding robots in the automotive industry plays an irsubstituteable role in welding robot is developed on the foundation of industrial robots, advance proceed go aheadd welding equipment, is engaged in welding (including cutting and spraying) of industrial robots, mainly used in industrial automation, its widely used in motor vehicles and parts manufperformanceuring, motorcycle, engineering machinery and other industries, in motorcar lorry truck car bus coach production stamping, welding, painting, assembly and four production processes are widely used, in which the most widely used in welding, spot welding based. At depict, widely used in industrial robots welding FAW, SAIC, Shenyang Shun, Jinbei GM, Chongqing Changan, Hunan Changfeng and other vehicle manufperformanceurers, according to statistics each vehicle body of the vehicle, there are almost 3000 to 4000 resistance spot welds, application of resistance spot welding skill technique to derive the amount of car body manufperformanceuring production and automation. Over the years, China's auto parts production has been a manual welding, welding plane welding retain the principle position, labor-intensive, adverse working environment, welding perthereforenality assurance is not easy, and the production flexibility is adverse, unable to adapt to the requisition of modern motorcar lorry truck car bus coach production . In recent years, due to the extensive use of welding robots, incralleviated parts production level of automation and production efficiency, while making production more flexible, welding perthereforenality is pledged. In recent years, the welding robot in Dalian Walker, Walker Shanghai, Shanghai Ma God, Nanjing New Di, Changchun Faurecia, Shanghai Huizhong and other parts and accesthereforeries, the company altherefore has a typical application. In the production of automotive components widely used in spot welding, projection welding, seam welding, arc welding and other welding processes. For example: tranthereforem bracket assembly spot welding, maintain shaft balance sheet projection welding, seam welding motorcar lorry truck car bus coach fuel tank, continuous flash butt welding car wheels, car steering arm, muffler, arc welding purifier housing and the resemble. With the advance of China's motorcar lorry truck car bus coach industry and the level of automation commandments continue to incralleviate, will furnish an eminent opportunity to fast-increasing markets of the welding robot. Expected ask for domestic enterprises welding robot will be more than 30% develppment rate. From robot skill technique advance trend, the welding robot to store the intelligent direction, coordination and integration of the full realization of population control production system of the robot, therefore as to derive vaster relicapacity and security. The use of welding robots in the automotive manufperformanceurer of high-tech, high-perthereforenality, low-cost condition will gain rapid advance, but altherefore will bring depend on date essentiality to the advance of the motorcar lorry truck car bus coach industry.
