How should domestic robots deal with themselves

, technology plays an important role. With the in-depth development of Internet technology, the era of Internet of everything is coming. In recent years, China's labor cost advantage has gradually lost, and the low-end manufacturing industry has begun to transfer to Southeast Asia and other countries, and the manufacturing industry has been upgraded. Ordinary manpower is not competent for the high-precision and high-quality advanced manufacturing industry represented by cars and consumer electricity for only more than 20 years, and the advantages of robots are gradually reflected

in this environment, the market of industrial robots has expanded rapidly. In 2016, the sales volume reached 89000 units, with an average growth rate of 36% in the first five years, while in 2017, the sales volume reached 111000 units, with a growth rate of 27.59%. It has maintained double-digit growth for many years. It is estimated that the sales volume will reach 200000 units by 2020

by the end of 2017, a number of projects have been arranged around the R & D and industrialization of RV Reducer, harmonic reducer, servo motor and controller. By 2019, they will be completed in succession, and the key parts of the robot will basically achieve autonomy. That is, 30% is solved by domestic brands, not all

robot has three core components: precision reducer, motion controller and servo drive motor. They account for 70% of the robot manufacturing cost to achieve reliable signal release and reception

nowadays, the gap between domestic and foreign controllers is the smallest. The status and threshold of the controller are relatively low. Mature robot manufacturers develop it independently to ensure its stability and corresponding maintenance technology. The market share is basically the same as that of the robot itself, so domestic enterprises making controllers still have great opportunities and fierce competition

the opportunity for controllers lies in standardization and openness. The existing robot controller has a closed structure, and its openness, fault tolerance and scalability are poor, so it can not adapt to the development situation of intelligence. Developing modular and standardized robot controllers and improving the openness to users at all levels is a development direction of robot controllers. China's 863 program has also been approved. Robot interface unification is a general trend, and platform enterprises providing controller modules may appear in the future. Therefore, China's robot controller manufacturing enterprises can develop in these aspects to adapt to the trend and seize market share

in terms of servo system, the situation is grim, and foreign-funded enterprises occupy an absolute advantage. Servo motor is the executive unit of robot, which is the main factor affecting the working performance of robot. Japanese brands have monopolized the small and medium-sized OEM (equipment manufacturing) market with good product performance and highly competitive prices, accounting for more than 50% of the market. European and American brands such as Rockwell, Danaher, Siemens and Bosch Rexroth also account for a large share. Accounting for only 10%, including central China CNC, Guangzhou CNC, Easton, Huichuan technology, etc

compared with foreign products, China's servo motors have more defects, which need to be vigorously developed in order to make a breakthrough, otherwise, it will be difficult to survive in the future market competition. First of all, the appearance of servo motors in China is rough, which is difficult to be applied to some high-end robots, especially desktop robots with a light load of about 6kg. Due to the limited space, there are strict requirements on the size and appearance of servo motors. Secondly, it is difficult to realize localization of high-precision encoder, which is heavily dependent on imports, and the situation is serious. Finally, the stability and reliability of the signal receiving plug-in need to be improved. At the same time, the industrial collaboration of all parts of the servo system is not enough, which makes it difficult to do a good job in the overall performance of the servo motor and drive system

however, in recent years, the state and enterprises have paid more and more attention to independent innovation, and China's servo system has developed quite rapidly. The independent supporting capacity has taken shape, and will enter a stable development in the next five years due to the impact of macro-economy. With the development of sensor skills, these weaknesses are the best breakthrough direction

in terms of reducer, it has broad prospects. In 2017, the sales of RV reducers produced by Nantong zhenkang reached 28000 units, and they have been exported in batches, and digital workshops are being built. The production capacity of 60000 units will be formed by the end of 2019. At the same time, Qinchuan machine tool has achieved the sales of nearly 10000 sets, and now it has also accepted foreign orders in batches. By the end of 2018, after the completion of digital vehicles, an annual production capacity of 60000 units will be formed

last year, Suzhou Greenland sold 98000 harmonic reducers, of which exports accounted for 15% and the domestic market share reached 60%. It has entered the international mainstream market. Moreover, they have realized the integration of harmonic reducer and servo motor, and are building the second phase of intelligent manufacturing production base, which will add 600000 sets of production capacity. Because the current production capacity is far from meeting the market, and the supply exceeds the demand. Shaanxi Weihe tool factory sells 20000 sets. By the end of 2018, a digital workshop with an annual output of 200000 sets will be built. By 2019, it can not only meet domestic demand to a large extent, but also export in batches

however, there are still some bad phenomena in China. In order to pursue the integrity of the industrial chain of our factory or enterprise, many robot industrial parks and processing plants also process all parts of the whole robot system, which means to make the industrial chain thick and long. But forget the truth that separation of mind leads to scattered effort. How can a factory have so much energy and ability to make all industries high, precise and sophisticated? The best situation is to make a relatively outstanding project, while others are slightly mediocre. In most cases, all parts projects are mediocre, wasting energy and going bankrupt. Moreover, such repeated construction will also seize the already small domestic market share. For example, when the domestic construction machinery industry was very popular, the three major construction machinery plants were in this situation, and finally one of them went bankrupt

foreign development experience is that robot manufacturers generally do not make their own reducers, and reducer manufacturers do not produce robots. Of course, some enterprises also want to pursue the integrity of the industrial chain, but they are unsuccessful. There are many similar examples, such as machine tools, generally do not do CNC systems. CNC systems generally do not do machine tools. It is also such a reason. Therefore, it is a misunderstanding for robot manufacturers and robot industrial parks to blindly pursue the integrity of the industrial chain. The key parts of robots should still be produced in large quantities by professional manufacturers who specialize in special products, so as to ensure quality and low cost and avoid vicious market competition. I think it should be able to meet domestic needs. Now at least dozens of enterprises are doing research work in this field, so I think we should do this without considering that this is a large market, otherwise the result is likely to be as tragic as the pressure parts in the fields of automobiles, aircraft and wind power blades, which are mainly used in automobiles, aircraft and wind power generation at present, and it is not as bad as that

in the face of this situation, first, we should cultivate specialized small giant enterprises to produce high-quality characteristic parts. Second, a series of development plans can be implemented around some of our key areas, especially those with characteristics. Third, build a one-stop service platform in key regions and industries. To improve the service quality and efficiency of the brand

in today's world, the key technology must be in our own hands. The country's important weapon cannot be given to others. If the robot industry wants to become a climate in China, it must also solve the problem of core parts and components. Although the development project of key robot parts is one of the five major focuses of made in China 2025, China's specialized enterprises engaged in the R & D and production of core parts and components have not yet grown up, so there is still a long way to go
