High-precision motors rely on imports. Domestic robots are slow to automate.

In recent years, China's robot industry has developed rapidly, and the domestic industrial robot market has achieved steady growth this year. The data shows that in the first half of 2015, a total of 11,275 industrial robots were sold, a year-on-year increase of 76.8%. It is estimated that the total sales of domestic industrial robots will exceed 22,000 units this year, an increase of about 30%.

However, Cai Hezhen, an academician of the Chinese Academy of Engineering, said at the 2015 China (Guangzhou) Robot Industry Development Conference: "China's robot industry has a big gap compared with developed countries." Mainly in the robots, high-precision motors and other products rely on imports. The core technology innovation capability is weak, the high-end product quality is low, the self-owned brand robot is difficult to promote and apply, the small, scattered and weak problems of the enterprise are prominent, the enterprise's competitiveness is lacking, and the system of robot standards and testing standards needs to be established.

Although China has been vigorously developing domestically produced robots in the past two decades, it has not yet established a robot industry with independent intellectual property rights, and has not been able to form a robot industry with a certain amount of production. So what is the reason for this situation?

The reporter interviewed relevant people in the industry. Xia Zhiyuan, a field application engineer of Vishay (China) Investment Co., Ltd., believes that the main reason is that there are many core devices that are not in the country at present. If foreign large enterprises dominate the entire core device market, domestic robots Production costs will be higher. Xia Zhiyuan said: "Now the entire robot industry needs more innovative companies to emerge. Robot manufacturers must also accept foreign manufacturers and cooperate with them. This will not only lower the overall cost, but also gain greater competitiveness. strengthen."

At present, the development of China's robot industry is still in its infancy. It must adhere to the enterprise as the mainstay and market-oriented, vigorously promote independent innovation, master core technologies, and have independent intellectual property rights. In addition to Xia Zhiyuan, Chen Peng, director of Shanghai Technology Department of Yokogawa Electric (China) Co., Ltd., believes that domestic robots are indeed criticized for not having independent intellectual property rights, and the main reason is that they do not have the core technology of the motor, which is needed by robots. High-precision motors have long relied on imports.

Chen Peng said: "Now we are also learning the technology of investing in the original factory in Japan, but the core technology of the motor is still difficult to master. As far as our profit level is concerned, it is difficult to achieve higher goals. The precision and reliability of the motor in the robot In terms of sex, there is still a certain gap between us and foreign robots. If we use Chinese motors, the accuracy is relatively poor. If foreign imported parts are used, the accuracy can be improved, but compared with foreign advanced robots. There is still a big gap."

With the "13th Five-Year Plan", China's robot industry is first and foremost thinking about how to break through the core technology of robotic motors and realize the autonomy of the industry, and then improve its level of intelligence, so that China can become a power producer from a large robot manufacturing country. .
