In recent years, with the further development of advanced manufacturing technology and new material technology, all over the world have set off boom in robot research and development. Su Bo, deputy minister of the Ministry of Industry and Information Technology, said that the high-end equipment manufacturing industry represented by robots is the core of the equipment manufacturing industry and an important indicator of a country's industrial competitiveness. China's robot technology and industry started late and must be accelerated Promote.
According to the classification of the International Robot Federation, the robot is divided into industrial robots and service robots. Luo Baihui, vice president of Dongguan Robot Technology Association, said that the original industrial robots were mainly used to replace heavy physical labor and complicated labor. The most widely used automobile manufacturing industry now extends to a wider range of fields such as food manufacturing and packaging. Although the service robot has not been applied on a large scale, it has been on the eve of industrialization.
Robots will have an alternative role to the workforce. Our country's labor force is rich in resources and does not seem to require the development of robots. In Luo Baihui's opinion, for China, the development of robots is particularly important. He analyzed that the rise of labor costs and high energy consumption make it difficult for China's traditional economic development mode to rely solely on resources inputs and must be transformed from "Made in China" to "Chi-making," while industrial robotics will be the main means of transformation And ways.
According to statistics, in 2013 China's industrial robot sales reached 36,860 units, an increase of 41%, surpassing Japan to become the world's largest robot market. Although the market size of our country is already the largest in the world, there is still tremendous room for development. In 2012, the number of industrial robots owned by every 10,000 industrial workers in our country was only 25, much lower than 347 in South Korea and 339 in Japan, less than half of the international average of 58.
It should be noted that the domestic robot industry is still lagging behind in the development of high-end industries such as automobile manufacturing, foreign market share of robots reached 96%, almost monopolistic position.
With the continuous growth of market capacity, domestic robots have developed rapidly in recent years. As of September this year, about 4,000 domestic robot companies, 49 robot industrial parks under construction in various provinces and cities. In the capital market, more than 60 listed companies have the concept of robots. Despite the surge in numbers, domestic robot manufacturers guarding the vast market are still unable to "get started".
Ling Lin, chairman of the world's advanced machine operator Tomohiro, said that there is a big gap between China's industrial robot industry and developed countries. China's own-brand industrial robots mainly focus on three-axis and four-axis coordinate robots and planar multi-joint robots, while six-axis multi-joint robots account for less than 6% of the total industrial robots sold in China. The multi-joint-type robots in the industrial robots sold by foreign-funded brands account for 62% of the total industrial robots sold in China. Their own brand products are far from meeting the development needs in various fields.
Technology behind because of the robot industry in China started late, another important reason is the weak ability to innovate. The number of patents made by robots can be seen. In 2013, the number of patent applications for robot inventions and utility models in China reached 4,350, but there was a serious lack of patents in the core technologies. Taking the RV reducer commonly used in robot manufacturing as an example, there are only 26 patent applications submitted by Chinese applicants and only 2 invention patents; 47 foreign applicants applied for patents in China and 26 are invention patents.
Wang Weiming, deputy director of the equipment industry department of the Ministry of Industry and Information Technology, pointed out that the innovation capability is weak, the core technologies and core key components are controlled by others, and the development of basic supporting capacity lags behind. The whole machine is facing the problem of empty shell. The manufacturing capacity of basic components in China is poor. Although there is a certain foundation in the related parts and components, there is a big gap with foreign countries in terms of quality, product series or bulk supply.
According to Yin Rongzao, chairman of Guangdong Bolante Intelligent Equipments Co., Ltd., innovation capability is weak and the quick success of domestic robotics enterprises rushes into mass production. The domestic robot enterprises are flourishing everywhere, with more than 140 robot-related enterprises and an average of one robot concept a week. However, there are only a dozen foreign robot enterprises.
The "Guiding Opinion on Promoting the Development of Industrial Robot Industry" put forward by the Ministry of Industry and Information Technology at the end of 2013 proposed that a relatively complete industrial robot industry system should be formed by 2020; the technical innovation capability and international competitiveness of the industrial robot industry and enterprises have been significantly enhanced, and the high-end market share Rate of 45% or more, the number of robots per 10,000 employees to reach more than 100 units.
In the current market environment, this goal can be achieved on schedule? Luo Baihui said it is possible but also difficult. After nearly 30 years of development, China's robot industry has initially established a research and development system from basic research of robotics to industrialization, and has formed a certain scale of production capacity of industrial robots. This laid a solid foundation for the robot industry development, the next robot manufacturers need to practice good "innovation" this internal strength.
Luo Baihui believes that the main problems facing domestic robots are the weakness of their own brands, the development of core components lags behind, the lack of high-end products and low-end excess capacity. Robot is a technology-intensive industry, to get out from the low end, the most important thing is the industry to get rid of speculative attitude, the focus shifted to technology research and development.
There is also a figure worth noting that the technological achievements of China's robot industry conversion rate of only about 3%. It is undoubtedly indispensable to improve the innovation ability of robot enterprises and improve the mechanism of transformation of production, learning and research. Tong Guofeng, deputy director of the Robotics Competition Working Committee of the Chinese Association of Automation , said that we need to mobilize the enthusiasm of inventors to innovate continuously, protect the inventor's work with intellectual property rights, establish a platform for cooperation between universities and enterprises, and improve the status quo of disjointing R & D and industry.
The good news is that many robot manufacturers have begun to attach importance to enhance innovation. The robotics industry technology innovation strategic alliance was formally established. The alliance will break through the robot common core technology through the joint research and make the technological achievements marketized, develop the robot series of products, create an innovation platform, and form a technical cooperation and intellectual property protection system. With more and more enterprises focusing on innovation, the market competitiveness and viability of China's robot enterprises will be significantly improved.
