At the academician meeting of the two academies on June 9, 2014, President Xi Jinping said that the "robot revolution" is an important entry point for the third industrial revolution. It is necessary to make great efforts to bring Chinese robots up, as much as possible. Dominate the market. There is something good, it will be even worse. A vigorous robot revolution has been carried out vigorously in major cities in China.
The situation in which companies enter the robot industry in different ways is almost crazy. According to incomplete statistics, as of the end of 2014, more than 70 listed companies have acquired or invested in robotics and intelligent automation projects, and the number of Chinese robot-related companies has exceeded 4,000. It is predicted that by 2020, the domestic robotic system integration market will reach 200 billion yuan, including 140 billion yuan for general manufacturing and 60 billion yuan for the automotive industry. It is expected that the automation demand of general manufacturing will grow rapidly in the next five years, and market demand will obviously exceed that of automobiles. In the industry, the market size will reach 70%.
However, the rapid development of China's robot industry is not a good thing for the industry, and even expressed concern. While China is vigorously promoting the development of the robot industry, China has also seen several negative factions that hinder the development of the Chinese robot industry.
The mediocrity: have been too much and not enterprising
China's robot market is in full swing, and there are many robot companies in China, but in fact, it is difficult for Chinese robots to come up with completely domestic robot products. China is guarding a world's largest robot market, but it is squeezed by foreign brands and is in a passive position.
Among the cost of industrial robots, the highest cost is the reducer, which accounts for about 35%, the servo motor accounts for about 25%, the controller accounts for about 15%, and the robot body accounts for less than 25% of the total cost. In the absence of core technology, the ontology robot enterprise can control the profit is limited.
Insiders in the industry do not blame the lack of core technology. The core component technology of industrial robots such as RV reducer, harmonic reducer, servo motor and drive, controller is still quite different from foreign brands. Most domestic robot companies gather on the robot body. The field is vying for meager profits and struggling on the profit and loss line.
Adding all kinds of factors, the purchase price of core components by self-owned brand industrial robot manufacturers is usually much higher than that of international brand industrial robot manufacturers. The price is not very strong or can only choose independent brands whose performance is difficult to guarantee. component.
At present, only a few companies such as Guangzhou NC, Nanjing Eston, and Shenyang Xinsong Robot are conducting independent research and development of core components such as control systems, drives and servo motors. Many domestic companies only integrate imported robots after purchasing imported parts, lacking core technology. The industry is concerned that in the long run, the "short core components" will cause the survival space of local enterprises to be squeezed. Due to the lack of core component technology, the bargaining space of Chinese enterprises in procurement is narrow, resulting in high cost and weak market competitiveness. .
朦胧派: just talk about ideals regardless of reality
The competition of industrial robots mainly focuses on three aspects of integrated application, mainframe cost and reliability. The technology of foreign-funded manufacturers keeps leading, and large-scale production has always maintained absolute cost advantage. At present, the main technical bottleneck of domestic robots is core technology and international The gap between the main competitors, if the core technology is solved through imports, the inevitable result is an increase in costs, which ultimately makes the products lack competitiveness.
The real gap between domestic and foreign is not in the robot body. The robot is only a third, but there is still a lot of application development, and the special technology of each industry is different. Taking welding as an example, there are several kinds of electric welding and arc welding. Each processing part is different. Does the technical application support keep up?
However, the reality is that the robots currently built in China may not be put into use in practice. "It is like a toy, the form is a robot, but the production line technology has not been solved, and the end user has stability problems. The robots that are made now have one hundred pieces in one hundred sets. How to achieve stability?"
The key to the development of robots is the application, the technical application package has not kept up, and who is it sold to? If it is not handled properly, who can guarantee that the robot industry will not fall into a similar situation with the automobile industry?
Robots instead of labor, mainly solve three levels of problems, that is, people can not do (special robots), people do not work well (high-end areas such as automobiles) and people do not want to do (domestic general manufacturing), "now to the stage where people do not want to do Need to use a lot of robots."
Not every field has to replace humans with robots. People do not have the high precision of robots, but they are adaptable. In some fields, it is very complicated to make robots. It is necessary to add a lot of sensors and measurement strengths. Only when the amount of information is large enough can be digitized, but many application fields are Can't be mathematically modeled.
