Industrial robot is the next generation technology war countries in a fight in the highlands, semiconductor manufacturing, automobile production, and medical equipment production, the mechanical arm will join in the future to build every industrial power industry background, is in so many areas, however, in three years, in 2018, The average localization rate of Industrial robots in China is only 30%. The bottleneck of some core parts of industrial robots hinders the development of industrial robots in our country. The harmonic reducer is one of them.
What is the use of harmonic reducer? Each joint movement of the robot is driven by a servo motor, which has the characteristics of large output speed and small output torque. The actual demand of the joint structure is low output speed and high rotational torque, so the output of the existing servo motor cannot meet the movement demand of the terminal mechanical body, so the structure of the reducer is needed for deceleration.
In other words, decelerators are like human tendons, connecting muscles and bones to make motion and limbs more coordinated
But many people do not know that it is such an important core component, our country has been stuck in the neck for a long time.
In the global scope, the manufacturers engaged in the development and production of precision reducer mainly include Nabotsk, Hamanaco, Nippon Shinbo, Sumitomo, and they are all Japanese companies. Among them, Hamonaker and Nabotsk are the absolute leaders in the deceleration industry, with the two companies accounting for about 70% of the global market share of industrial robot decelerators. The two Japanese speed reducer companies can be seen on many production lines and industrial products in China.
China began to break the monopoly of Japanese decelerators in 2011. In 2011, a company named Green Harmonic was born in Suzhou, Jiangsu Province. It was the first company in China to realize the industrial production and large-scale application of harmonic reducer, which broke the long-term monopoly of Japanese brand in domestic robot harmonic reducer field. In March 2011, the company's first reducer prototype was sent to Jiangsu Reducer Product Quality Supervision and Inspection Center for testing. A technological breakthrough has been achieved. And at present, the green harmonic also became the representative of domestic gear reducer, occupies more than 60% market share in the domestic independent brand robot, at the same time, green harmonic harmonic reducer reducer in the global share of 6.16%, also in a city its harmonic reducer shipments after Japan hammer naco, is the world's second largest harmonic reducer production enterprise. In 2020, green Harmonic landed on the science and technology innovation Board and went public, which has also become a very typical representative of The characteristics of Chinese specialization.
As an important part of industrial robot, harmonic reducer has been monopolized by Japanese enterprises for more than 30 years. However, this situation was broken by a little-known Private Chinese company in 2013. Can we replicate this experience in other areas of difficulty?
I think it's very likely, but there are a couple of prerequisites
The first premise is that there is already a basic accumulation of technology in our relevant field. Green harmonic start is not totally layman, the predecessor of the company, was founded in 1999, registered in 2003 in suzhou heng metal products co., LTD., the company, to do precision machining foundry, silent and accumulation in the field of precision machining for many years, even though the value of the contract in the whole industry chain in the low end, the gold content is not high, However, with low cost, the price of the parts and components of these products sold to Europe is only about 20 or 30 percent of that of local European enterprises, which makes Green Harmonic in early years, in fact, has entered this industry, and began to sleep on hardships and accumulate technology.
The second premise is that alternative opportunities emerge in relevant markets. How does an OEM get into precision instruments? The key factor behind this is the opportunity to replace suppliers caused by competitors' mistakes. Around 2003, by chance, green Harmonic executives heard the staff of the international robotics giant complaining about the Japanese company's high monopoly on harmonic decelerators. And this complaint, only left Yu Yu was born to be able to find the market opportunity of reducer.
Third premise is the original innovation spirit, the technical accumulation, with the market opportunities, to ultimately achieve broken, is to break through the technological monopoly original spirit, in the green of the harmonic certain direction, resolutely decision from the contract of the red sea into blue ocean of harmonic gear reducer, unceasingly will work all the tens of millions of profits each s "hit" into research and development of harmonic gear reducer, Green in the harmonic reducer technology research and development before and after a total of more than 200 million costs, which for a OEM private enterprises, or very "crazy". It is this original spirit of innovation that enables China's domestic reducer market share to continue to improve.
The rise of Chinese robot harmonic reducer is a very typical process of breaking monopolies in specialized new fields. If you know any other similar examples, please tell me in the comments section, and I will explain the story of China's technological rise that you are interested in in future articles.
