In industrialized countries, industrial robots have experienced rapid development in nearly half a century, and their technology has become increasingly mature. They have been obtained in many industrial fields such as automobile industry, mechanical processing industry, electrical and electronic industry, rubber and plastics industry, food industry, logistics, manufacturing and so on. A wide range of applications. As an irreplaceable important equipment and means in advanced manufacturing, industrial robots have become an important indicator to measure the manufacturing level and technology level of a country. Statistics from the International Federation of Robotics (IFR) show that in 2011, there were 139,300 new robots installed worldwide, an increase of 18% over 2010. With the continuous development of emerging applications, it is estimated that by 2014, the annual global industrial robot production will grow at an average annual rate of 6%, with an average of 167,000 new units per year. At the same time, Asia will become the fastest growing region in the industrial robotics industry. The development status of industrial robots in China China's industrial robot research began in the 1970s and can be roughly divided into four stages, namely, the theoretical research stage, the prototype development stage, the demonstration application stage, and the preliminary industrialization stage. The previous theoretical research began in the 1970s and early 1980s, and the research units were distributed in some universities in China. At this stage, due to the constraints of national economic conditions and other factors at the time, it mainly engaged in the research of basic theory of industrial robots, and made certain progress in robot kinematics and institutional science, which laid the foundation for the subsequent research of industrial robots. In the mid-1980s, as industrialized countries began to apply and popularize industrial robots in large quantities, the research of industrial robots in China received the attention and support of the government. The state organized research on the industrial robot demand industry, invested a large amount of funds to carry out industrial robot research, and entered the prototype development stage. In 1985, China included industrial robots in its development plan in its scientific and technological research program. In 1986, China incorporated intelligent robots into the national high-tech research and development plan. At this stage, it carried out the research on the basic technology of industrial robots, basic components, and prototypes of several types of robots. It has developed spot welding, arc welding, painting, Handling robot prototypes, harmonic drive components, and welding power supplies have formed the first climax of the development of industrial robots in China. Demonstration application phase for industrial robots in the 1990s. In order to promote the close connection between high-tech development and the main battlefield of the national economy, the development strategy of special robots and industrial robots and their application engineering is determined, and the application of key technologies and basic research is applied. At this stage, a total of 7 industrial robot series products, 102 kinds of special robots, and more than 100 robot application projects were developed, including plane joint type assembly robot, Cartesian coordinate robot, arc welding robot, spot welding robot and automatic guided vehicle. Among them, 58 key technologies and applied basic technology research achievements have reached the international advanced level. They have won 2 national science and technology progress awards, 116 provincial and ministerial level scientific and technological progress awards, 38 invention patents and 125 utility model patents. At the same time, in order to promote the industrialization of domestic robots, in the late 1990s, nine robot industrialization bases and seven research bases were established, including Xinsong Robotics Co., Ltd. of Shenyang Automation Research Institute, Harbin Bosch Automation Equipment Co., Ltd., and Beijing Machinery Industry. The Robotics Development Center of the Institute of Automation has laid the foundation for the development of China's robot industry. In the 21st century, the national medium- and long-term science and technology development plan outlines the main line of enhancing independent innovation capability, and strives to create a policy environment conducive to independent innovation, accelerate the promotion of enterprises to become the main body of innovation, vigorously advocate enterprises as the main body, and closely combine production, study and research. A large number of domestic enterprises have independently developed or cooperated with scientific research institutes to enter the ranks of industrial robot development and production. China's industrial robots have entered the stage of initial industrialization. At this stage, dozens of companies engaged in the production of industrial robots such as Xinsong Robot, Bosch Automation, Chery Equipment, Juyi Welding, Wide Number, Wodi, and Qingdao Soft Control have emerged. Representatively, six RD120-A spot welding robots and Type II resistance welding controllers developed by Shenyang Xinsong Company have realized the front and rear windshields of the body lines of Xiaohongqi and Century Star. And the left and right door spot welding and welding work turnkey project. Xinsong AGV robot is widely used in automobile manufacturing, machining, electronics, textile, paper, cigarette, food, printing, book publishing and other industries, occupying more than 70% of the domestic AGV market, and entering the international market, has been exported to the United States. Countries such as South Korea, Russia, and Canada have pioneered the export of domestic robots. The handling robot developed by Harbin Bosch Automation Equipment Co., Ltd. is widely used in the post-processing production line of powder and pellets in the petrochemical industry, achieving an annual sales of nearly 100 units. Tianjin University has developed three series of new products of 2~4 degrees of freedom high-speed handling robots with independent intellectual property rights and outstanding international performance, such as Diamond, Delta-S and Cross-IV. In lithium battery sorting (Tianjin Lishen application) , pharmaceutical soft bags (Beijing Shuanghe Pharmaceutical Application), fruit milk and plastic explosives (Yunnan Anhua application) more than 10 packaging and handling automation production lines have been successfully applied. The complete welding technology of the automobile body-in-white robot of Juyi Automation Co., Ltd. has been widely used by domestic vehicle manufacturers such as FAW, Dongfeng, Beiqi, Chery, Jianghuai, Great Wall and other foreign vehicle companies in Iran and Egypt to provide welding for customers. More than 40 production lines. The 165kg spot welding robot developed by Chery Equipment Co., Ltd. and Harbin Institute of Technology has been applied online for about 50 sets, which are used for welding, handling and other occasions. It has independently developed China's first domestic robot automatic welding production line, which can realize the S11 model. Production of side panels. The above results show that a new situation in the industrialization development of industrial robots in China has taken shape. In summary, the development of industrial robots in China has experienced a series of national breakthroughs. The application engineering development supported by the plan has laid the foundation for China's independent development of the robot industry. However, China's industrial robots still have a large gap in overall technology compared with foreign advanced levels, which is only equivalent to the level of foreign countries in the mid-1990s. At present, the production scale of industrial robots is still small, most of them are single-piece small batch production, and the key supporting unit components and devices are always in the state of import, and the cost performance of industrial robots is low. With the rapid growth of China's economy and the demand of automobiles and other industries, China's demand for industrial robots has increased sharply. Well-known international industrial robots such as ABB and FANAC have set up factories in China. The prices of foreign famous industrial robots have been declining year by year. The formation of China's industrial robot industry and The challenges facing the development of industrial robots in China With the rapid development of China's economy and the continuous improvement of labor costs, the development of high-tech industries and the improvement of manufacturing automation level, from labor-intensive to technology-intensive has become the only way for economic development model and manufacturing industry restructuring. It is estimated that by 2014, China will become the world's largest demanding country, providing a good opportunity and huge development space for the development of China's industrial robots. In order to meet the needs of the rapid development of industrial robots in China, we are faced with multiple levels of challenges. At the level of understanding, robots are the core equipment that best reflects the "high-end, intelligent" characteristics of intelligent manufacturing. The "high-end equipment manufacturing industry" is listed as one of the seven strategic new industries. The industrial robot industry is important as a high-end equipment manufacturing industry. As an integral part, the independent development of industrial robot technology is an important means to improve the level of intelligent manufacturing in China. It is necessary to form a unified understanding within the government, enterprises, research institutions, etc., to create a scientific atmosphere for the promotion and development of industrial robots, and to form a national power for the development of industrial robots. At the strategic level, smart manufacturing has become the core of strategic emerging industries that the country focuses on cultivating and developing. The demand for industrial robotization by intelligent manufacturing continues to grow rapidly. Therefore, we must seize the opportunity, clarify the goal, speed up the pace, and develop rapidly; we must form a dominant industrial chain for industrial robot manufacturing; we must master the core technology of industrial robots that serve the manufacturing industry. At the application level, China's industrial robot application market is becoming more and more mature. Compared with foreign countries, there are fewer application fields and the product types are not rich enough. Therefore, it is necessary to comprehensively explore, explore a wider range of application areas and industrial robots to serve development models, service content, and common technologies in various fields; focus on breakthroughs, and realize the core technology of industrial robots for the manufacturing needs of cutting-edge fields such as defense, aviation, and aerospace. Key breakthroughs; perfect structure, establish a complete system of R&D, production and market for industrial robot system-level solutions for different application fields. On the technical level, the new concept of modern intelligent manufacturing puts forward many new requirements for the development of industrial robots. The multi-variety and small-scale development trend of manufacturing products brings elastic production demand, requiring industrial robots to have high flexibility and high integration; manufacturing professional subdivision and more complex manufacturing processes require industrial robots to be more intelligent and fine-grained; manufacturing The ever-shrinking product life cycle requires industrial robots to have the ability to quickly update and upgrade. The industrial robots must improve their performance while following the green manufacturing concept characterized by low energy consumption and low emissions.
