The author:SIPO  Time:2018-04-03  Read: 181
With the switching of industrial robot applications, the future demand will be applied in a large number of new scenarios. The large-scale demand in the automobile, 3C, or home appliances era will focus on cutting, welding, loading and unloading, etc., at the production end. The application of links, such as logistics and packaging, has just started and the market investment environment is excellent.

According to statistics, from 2010 to 2015, China's industrial robot market sales increased at an average annual rate of 35.5%. In 2015, the sales volume of industrial robots reached 68,000 units, which accounted for more than 1/4 of global sales, and actual sales increased by 31.3% over the previous year. For three consecutive years, it has become the world's largest industrial robot market.

From the perspective of investment opportunities in industrial robots, the first is the motion controller market. The markets of medium and large-sized enterprises and multinational companies in China are relatively mature. The overall market size of China is about 7 billion yuan, and it will grow at an annual rate of 11% in the coming years.

Since last year, China has successively issued documents such as "Made in China 2025" and "Robot Industry Development Plan (2016-2020)" and strives to reach 150,000 sets of industrial robots with a holding capacity of 800,000 units by 2020. The annual output of the robot is up to 100,000 units, and the market share is 67%. The self-sufficiency rate of key components is over 50%, forming a relatively complete industrial system.

Recently, Yang Shuchang, Deputy Director of the Ministry of Industry and Information Technology of the Ministry of Industry and Information Technology, told the media that China will speed up the establishment of a national robot innovation center, and encourage regional establishment of regional robot innovation centers to break through key technologies.

Human-Machine Fusion is the Only Way for Robot Development

Gu Chunyuan, chairman and president of ABB China Co., Ltd., said that in today's world's most advanced flexible automated production line, a vehicle can be offline in less than one minute; in the Changan Ford plant, six different models can be produced on the same production line. The switching of each model takes only 18 seconds. The core technology is to organically integrate the robotic arm with surrounding fixtures and other related equipment through a three-dimensional system. “It's a very mature technology,” he said. “This is not a human-machine fusion, because the machine is completely separated from people. "The future of human-computer interaction and integration will enable people and people to connect organically through technical services, and from Chinese manufacturing to China's intellectual creation."

At present, it is impossible to completely replace humans with robots. However, through the integration of humans and robots, the simplicity of robots can be greatly improved and the entire application of robots can be qualitatively changed. Regarding the security of human-computer communion, according to international security standards, corresponding requirements have been put forward for security, but there are many ways to achieve this and various approaches. Only when it is truly fenceless and multiple technologies are combined can we achieve ultimate security.

How to combine people and machines is the only way for the development of the robot industry. At present, human-machine integration is the main trend of intelligent industrial robots. In order to make robots match people better, we need to study what people have? People first have absolute flexibility, followed by sight and touch. At present, the traditional robot is far more human than the human in terms of speed, accuracy, and reliability of simple tasks. However, the gap between flexibility, tactile and visual parts and people is still very large.

Professor Meng Qinghu of the Department of Electronic Engineering of the Chinese University of Hong Kong has raised the question: Can robots replace people? This problem stems from the following mythological classic phenomena: how accurate, efficient, and dexterous the robot in the industrial assembly line is, and how it can be extremely awkward when dealing with most life matters (such as simply stacking clothes, going up and down stairs, etc.). Meng Qinghu compared the human-machine comparison of mobile performance, flexibility, operability, sensing capabilities, and intelligence. He discovered that the main gap in current robotics is flexibility and intelligence, especially in intelligence. "There is still a long way to go to tell the truth." go". Human cognitive methods and process machines are still difficult to imitate, and the mechanism of interaction between the human brain and the body can't be perfectly reproduced. It contains enormous technical challenges in the fields of software and hardware. Therefore, we really want robots to integrate into our lives. "One prerequisite is that robots must know the existence of people and be able to survive with them." This requires that robots' identification and cognitive abilities are greatly improved, robots become part of society, and the era of human-machine integration really comes.


Foreign-funded enterprises frantically rush to eat Chinese market


Under the catalyzed “Made in China 2025” policy, the sales volume of Chinese domestic brand industrial robots will increase from 22,300 units in 2015 to about 31,000 units in 2016, and will also share the market of some Japanese and European brand industrial robots in China. Pie.

In addition to Japanese factories Epson, Yaskawa Electric and Fanuc, which have set up factories in China to produce and sell industrial robot products, ABB Switzerland and Kuka in Germany also set up factory cards in China.

Among them, the industrial robot products manufactured and sold by these robot manufacturers in the Chinese market are mainly based on automotive applications. Other applications include metal processing, electronic product assembly, and food, cosmetics, and other types of packaging.

In the past 10 years, China has become the world's factory for 3C electronic products. In addition, China has actively raised the salary level of labor in recent years, making these foundries face high personnel costs and squeeze their profitability.

As a result, these manufacturing companies began to make machine-for-machine moves in order to reduce the ever-increasing personnel costs.

For this reason, in addition to promoting small industrial robot products, global robot manufacturers also actively promote collaborative robot products with built-in sensors.

In addition to the global robot manufacturers who have flagged and promoted collaborative robots in the Chinese market, Japan Kawasaki, who announced duAro as a collaborative robot product in 2015, also seized the opportunity to set up factories in China to produce and sell its collaborative robot products. .

Kawasaki pointed out that in a production line that requires 10 people, five collaborative robots can be used instead of five humans to complete the assembly of electronic products and cosmetic packaging.

 

Kawasaki's 51% joint venture company in China will be responsible for the construction of a new factory in Chongqing, will fully supply the Chinese market demand, no longer imported from Japan.

The new plant is scheduled to be put into operation before the end of 2016. The capacity for the first year will be 1,000 units. In the future, the annual output will be increased to 5,000 units. Major components such as bearings, reducers, and motors will be imported from Japan, and some will be imported from China. Manufacturer purchases.

Robot industrialization has to grasp the core components

After the intelligent manufacturing booster robot became an important role, the core technology became the primary factor in the consolidation of the market position in the major robotics industry. In addition, the three core components of industrial robots account for half of its cost, and it has to be said that whoever owns the three core components will win one step at the starting line.

Driving China November 22, 2016 News After the intelligent manufacturing booster robot became an important role, the core technology became the primary factor in the consolidation of the market position of the major robotics industry. In addition, the three core components of industrial robots account for half of its cost, and it has to be said that whoever owns the three core components will win one step at the starting line.

The three core components of industrial robots are controllers, servo systems, and speed reducers. The controller is expected to have a market size of 1.2 billion yuan in 2020, a piece of fat. As the robot's brain, it releases and transmits action instructions. In the hardware part of our country has been basically grasped, but there is still a certain gap between software and foreign brands.

6365834525679604032184233.jpg

In 2015, China's controller market reached 2.31 billion yuan, an increase of 18% year-on-year, of which industrial robot controllers accounted for 15%, about 350 million yuan. However, the existing industrial robots in China need to be improved in terms of intelligence and flexibility. The development of standardized and open controllers has tremendous room for development. By 2020, China's industrial robot controller market is expected to reach 1.2 billion yuan, the compound growth rate in the next five years is about 27%.

Servo system is an important part of industrial automation. It is a necessary way to achieve accurate positioning and precise movement in the automation industry. The joint drive of the robot is inseparable from the servo system. In recent years, the rapid expansion of industrial robots, electronic manufacturing equipment and other industries has seen rapid growth in the application of emerging industries.

Currently, Japanese brands account for half of the market for servo systems in China. The share of foreign servo companies in China is 75%, of which Japanese brands account for 50%. However, with the improvement of the performance of domestic servo systems, the share of domestic servo products is expected to expand.

The last major pillar is the reducer, which is the intermediate device between the power source and the actuator. There are two types of reducers used in industrial robots: RV reducers and harmonic reducers.

With the development of industrial robots in the future, China Investment Consulting Industry Research Center predicts that by 2020 China's industrial robot reducer market will exceed RMB 4 billion, and its compound growth rate will be approximately 30% in the next five years. Despite the strong demand for China's industrial robot reducers, the production capacity of domestic reducers lags far behind Japan, the United States, and Europe.

In a comprehensive view, the industrialization of industrial robots in China needs to be further improved. The most important thing is that the core parts and components market has yet to be broken, because these basic resources will directly affect the upgrading of China's robot industry.

Machine vision is promising

As a key technology that brings visual functions to robots, machine vision is widely used. From industrial vision to computer vision, from human-computer interaction to automatic driving, from virtual reality to automatic object recognition, machine vision can play an important role.

Industry 4.0 is inseparable from intelligent manufacturing, intelligent manufacturing can not be separated from machine vision. If the industrial robot is an extension of the human hand and the vehicle is an extension of the human leg, then machine vision is equivalent to the extension of human vision on the machine and is an essential means to achieve industrial automation and intelligence. Machine vision has the advantages of high automation, high efficiency, high precision, and poor adaptability to the environment, opening up a "new horizon" for industrial automation in China.

The application of machine vision to robots is very necessary. Both industrial robots and service robots need robot vision as their own "eyes", but industrial robots and service robots have different requirements for robot vision.

Using the method of machine vision, you can quickly and accurately detect whether the pharmaceutical packaging is intact. By setting the image sensor, you can obtain the image information of the packaged object, and test each drug particle or vial through a preset area parameter. In contrast, in this way, broken pills or missing bottles will be detected and correctly passed.

The difference between machine vision and industrial robots is the application scenario. In the context of industrial robots, the scenes seen by computer vision are relatively single, but the application scenarios of service robots are much more complex. Outside the scene, it is the accuracy aspect. In industrial robots, the accuracy of computer vision recognition must be below the millimeter level, including static identification accuracy and dynamic identification accuracy. Static refers to the relative position of the camera or the observed item in a stationary state. It identifies this time. The accuracy depends on the resolution of the camera, including whether the edge of the item is clear and the differentiation is very clear. At this time, the accuracy can even reach the micron level. Most of the precision of the service robot is not very high and may be more than centimeters.
