Industrial robots: show great value under the epidemic

industrial robots have undertaken a large number of tasks in the front line of anti epidemic, and also played an important role in the resumption of work and production. In the future, the value of industrial robots in industrial manufacturing, logistics distribution, catering and retail, security patrol, rehabilitation and health care will be further highlighted Since the outbreak of the epidemic, the application of industrial robots has attracted more attention. In the front line of anti epidemic, robots undertake auxiliary medical treatment, food and medicine delivery, temperature measurement and disinfection, which improves efficiency and reduces the possibility of cross infection. In the recent resumption of work and production, enterprises with a high degree of automation and intelligence have been least affected by the labor shortage, and the value of industrial robots in industrial manufacturing, logistics and distribution, catering and retail, security patrol, rehabilitation and health care has also been further highlighted. It can be said that industrial robots will play an increasingly important role in the transformation of new and old kinetic energy in China in the future

at present, the development of China's industrial robot industry is still facing a big but not strong problem

lack of independent innovation ability and core patents. Compared with developed countries, the development of industrial robots in China started late and the technology is relatively backward. Domestic enterprises generally have problems such as weak awareness of independent innovation and insufficient R & D investment. The lack of core patents and high technical barriers of foreign enterprises will restrict the further development of the domestic industrial robot industry. The three core components of industrial robot are servo motor, controller and reducer. In recent years, multinational giants such as FANUC, abb, Yaskawa and KUKA have increased the intensity of patent layout in China, and the patent applications in the three key technology fields account for about half of the patent applications of multinational companies in China. As the core parts are monopolized by foreign enterprises, the patents of domestic applicants are mostly concentrated in the field of non core parts such as end effectors, joints, manipulators, etc. Although China is the largest application market of industrial robots, about 70% of the market is occupied by these foreign-funded enterprises that have mastered the core technology

the industrial chain is not perfect, and core parts still rely on imports. The industrial robot industry chain is divided into upstream, midstream and downstream. Among them, the upstream mainly produces servo motors, controllers, reducers and other core parts, accounting for 65% - 75% of the overall cost of industrial robots; The midstream is body production, including mass use seats, wrists and other body parts of arm and bottom plastic products; Downstream is system integration, including single system integration and integrated system integration. At present, China's middle and downstream industries are developing rapidly. About 80% of industrial robot enterprises are concentrated in the field of system integration with competitive advantages, but there are generally problems of small scale and less output value. However, the upstream industry has not made a major breakthrough. The three core components, especially the reducer called the brain of industrial robots, are heavily dependent on imports, and the import price is about 5 times that of foreign enterprises, resulting in higher costs for domestic industrial robots and the industry facing the risk of hollowing out

low export added value and lack of competitiveness of products. The robot industry is originally a three high technology, capital and talent industry, but now it is facing the dilemma of low added value. Due to high cost and lack of core technology, industrial robots in China lack sufficient competitiveness both at home and abroad. As the largest industrial robot application market in the world, China's domestic industrial robots have a market share of only 30%, and are concentrated in the middle and low-end fields, and the share of domestic robots in the high-end fields is less than 5%. In the market of multi joint robots with more than six axes, transnational giants such as FANUC, abb, Yaskawa and KUKA account for 90% of the market share; In the automotive industry where high-end applications are concentrated, foreign companies account for 90%

the industry standard system is not perfect, and the cross repetition of standards is serious. Many standards institutions and industry organizations in China are actively promoting the construction of industrial robot standards. At the same time, many domestic experts have also participated in the formulation of international standards for industrial robots. Although some achievements have been made in China's standardization work, there are still some problems, such as the imperfect industry standard system and serious cross repetition of standards. Some traditional robot standards need to be revised and improved, system integration and related testing and evaluation standards need to be supplemented, new product and technical standards need to be followed up, and Chinese standards need to be connected with international industrial robot standards

lack of professional talents. In terms of manufacturing, servo motors, controllers and reducers have become the main bottlenecks restricting China's industrial robot industry, and China is extremely short of technical personnel in this field. In terms of application, there is a talent gap of nearly 100000 industrial robots in China at present. According to the development plan of the Ministry of industry and information technology, by 2020, the installed capacity of industrial robots in China will reach 1million, and the number of industrial robot applications such as corresponding operation and maintenance, system installation and commissioning, and system integration will reach about 200000. However, at present, China's colleges and universities have not specifically set up industrial robot related majors. Industrial robot programming, maintenance and other staff are mainly from the secondary training of graduates of electrical automation, electromechanical engineering and other majors, and the short-term training effect is not good. In terms of system integration, the transformation of the industrial robot industry requires more than 5 years of work experience, and there are also few talents in this field

industrial robots are not only the representatives of advanced manufacturing industry, but also the key development areas determined by made in China 2025. As the country with the fastest growth rate of industrial robot density in the world, China must seize opportunities and meet challenges with a greater sense of urgency to promote the industrial robot industry from big to strong

strengthen independent innovation and improve the industrial chain system. At the national level, policy support should be provided for the development of the industrial robot industry, and preferential scientific research subsidies should be implemented to encourage the development of robots and their application systems. Industrial robot manufacturing enterprises should increase investment in research and development, focusing on the development of high-precision reducer, harmonic reducer, high-speed and high-performance robot controller, high-precision robot special servo motor and servo driver and other core components; Guided by application, Mr. Li from Shijiazhuang, Hebei Province visited our company and cooperated with manufacturing enterprises yesterday to understand their specific needs and provide them with integrated solutions; Pay attention to the undeveloped application fields and implement key breakthroughs. At the same time, relying on universities and scientific research institutions, explore the cooperative fatigue testing machine of industry, University and research, which is a high-tech equipment system to promote the industrialized application of scientific and technological achievements

accelerate the formulation and implementation of industrial standardization. The government should speed up the legislative process of industrial robot industry and promote the industrialization of industrial robots; Allocate special funds for industrial robot standardization and establish public service platforms for robot standardization, modularization and other shared technologies to promote the smooth progress of industrial robot standardization. The industrial alliance should cooperate with industrial robot manufacturing enterprises, universities and scientific research institutions to speed up the construction of industrial robot standard system, revise some traditional robot standards, supplement system integration and testing and evaluation standards, and follow up new product and technical standards. Give priority to the research and development of basic standards and safety standard systems for industrial robots with independent intellectual property rights, so as to lay the foundation for promoting industrial robots to the market

optimize import and export policies and actively adapt to the international market. In view of the relative concentration of China's importing countries, we should expand foreign trade, prevent a single country from locking in China's trade, and maintain the multilateral trade mechanism. When entering the international market, industrial robot enterprises should timely and comprehensively understand the market information and take preventive measures. In case of trade friction, they should timely adopt emergency plans and actively respond to lawsuits to reduce losses. Enterprises should also actively seek interest alliances, cooperate with foreign suppliers and sellers, and jointly exert influence on the governments of relevant countries to reduce the adverse impact of trade friction on enterprises. Strengthen the exchange and cooperation with relevant foreign standardization organizations such as ISO and IEC, strive to integrate Chinese standards with international standards, and reduce unnecessary trade frictions

integrate educational resources and vigorously cultivate applied talents. The life cycle of industrial robot products needs to go through such links as product scheme, integrated design, technology implementation, process application and operation and maintenance. In terms of specialty setting, it is necessary to establish the corresponding curriculum system according to the work skills required by each post. In terms of teaching resources, we should integrate excellent industry resources, transform industry technology into corresponding educational resources, and implement them into specific teaching courses as soon as possible. In terms of teaching methods, in addition to theoretical learning, we should add practical links, establish close contact with relevant industrial robot enterprises, and regularly organize enterprise visits, internships and other activities. At the same time, we should establish a vocational skill training system for industrial robots, strengthen the series training of industrial robot practitioners, and issue corresponding professional skill certificates to those who pass the examination
