With the switching of industrial robot application fields, future demand will be applied in large scale in some new scenarios. The large-scale demand in the era of automobiles, 3C or home appliances is concentrated in the production process of cutting, welding, loading and unloading, etc. Application links, such as logistics, packaging and other aspects of the application have just started, the market investment environment is good.
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, accounting for more than 1/4 of global sales. The actual sales volume increased by 31.3% over the previous year. It has become the world's largest industrial robot market for three consecutive years.
From the perspective of industrial robot investment opportunities, the first is the motion controller market. The market for China's medium and large-sized enterprises and multinational companies is relatively mature. The overall size of China's market is about 7 billion yuan, and there will be an annual growth rate of 11% in the next few 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 sell 150,000 industrial robots by 2020, holding 800,000 units, domestic industry. The annual output of robots reaches 100,000 units, with a market share of 67% and a self-sufficiency rate of over 50% for key components, forming a relatively complete industrial system.
Recently, Yang Yichang, deputy director of the Equipment Industry Department of the Ministry of Industry and Information Technology, told the media that China will accelerate the formation of the National Robot Innovation Center and encourage qualified regions to establish regional robot innovation centers to break through key technologies.
Human-machine integration is the only way for robot developmentGu Chunyuan, chairman and president of ABB China Ltd., said that in today's world's most advanced flexible automation production line, one car can be off the assembly line in less than a minute; in Changan Ford factory, six different models can be produced on the same production line. Switching between each model takes only 18 seconds. The core technology lies in the organic integration of the mechanical arm with the surrounding fixtures and other related equipment through the three-dimensional system. "It is already a very mature technology," he said. "But this is not a human-machine fusion, because the machine is completely separate from people. In the future, human-computer interaction and integration can realize the organic connection between things and people through technical services, and build from China to China.
At present, it is impossible to completely replace human beings with robots, but through man-machine integration, the simplicity of robots can be greatly improved, and the whole application of robots can be qualitatively changed. As for the safety of human-computer integration, the safety requirements have been put forward according to international safety standards, but how to implement a lot of methods, a variety of practices. Only by truly being fence-free and combining multiple technologies can the ultimate security be achieved.
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 industrial robot intelligence. In order to make robots better match people, what kind of capabilities do we need to study? People first have absolute flexibility, followed by vision and touch. At present, the traditional robots are far superior to humans in terms of speed, accuracy, and reliability of simple repetitive operations, but the gap between flexibility, touch and vision is still very large.
Meng Qinghu, a professor of electrical engineering at the Chinese University of Hong Kong, asks, can robots replace people? The problem stems from the following puzzling classics—accurate, efficient, and dexterous robots on industrial lines that perform awkwardly when dealing with most life issues (such as simple stacking, up and down stairs, etc.). Meng Qinghu's comparison of manpower and machine performance in terms of mobile performance, flexibility, operability, sensing capability and intelligence found that the main gap between current robots lies in flexibility and intelligence, especially in terms of intelligence. "To tell the truth, there is still a long way to go. go". Human cognition and process machines are still difficult to imitate, and the machine of the brain and body's linkage reaction mechanism can't be reproduced perfectly. It contains huge technical challenges in the field of software and hardware. So, really want robots to integrate into our lives, "One prerequisite is that robots must know the existence of people and be able to live with others." This requires the recognition and cognitive ability of the robot to be greatly improved, and the robot has become a part of society, and the era of human-computer integration has really come.
Foreign companies frantically rush to the Chinese marketUnder the catalysis of the "Made in China 2025" policy, the sales volume of Chinese domestic brand industrial robots will increase from 22,300 units in 2015 to approximately 31,000 units in 2016, and relatively share the market of some Japanese and European brand industrial robots in China. Big cake.
In addition to the Japanese factory Epson, Yaskawa Electric and Fanuc have set up factories in China to produce and sell industrial robot products, as well as Switzerland ABB and Germany Kuka also set up factory cards in China.
Among them, the industrial robot products produced and sold by these robot manufacturers in the Chinese market are mainly used in the automotive industry, and other applications are metal processing, electronic product assembly, food and cosmetics, and other related 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, which makes these foundries face high personnel costs and squeeze their profit margins.
As a result, these manufacturing companies began to take the action of machine substitution, in order to reduce the increasing personnel costs.
To this end, in addition to promoting small industrial robot products, global robot manufacturers are also actively promoting collaborative robot products with built-in sensors.
In addition to the global robot manufacturers in the Chinese market to flag and promote collaborative robots, Japan's Kawasaki, which released the collaborative robot product duAro 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, 5 cooperative robots can replace 5 human forces, and the assembly of electronic products and cosmetic packaging can be completed.
Kawasaki's 51% Chinese joint venture will be responsible for building a new plant in Chongqing, which will supply all of the Chinese market demand and no longer import from Japan.
The new plant is scheduled to go into production before the end of 2016. The first year's capacity will be 1,000 units, and the annual production will increase by 5,000 units. The main components such as bearings, reducers and motors will be imported from Japan, and some will be imported. Purchase from local manufacturers in China.
Robotic industrialization captures core componentsWith the intelligent manufacturing boosting robots playing an important role, the core technology has become 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 their cost. It must be said that whoever owns the market for these three core components will win a step on the starting line.
Driving China November 22, 2016 News With the intelligent manufacturing boosting robots playing an important role, the core technology has become 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 their cost. It must be said that whoever owns the market for these three core components will win a step on the starting line.
The three core components of industrial robots are controllers, servo systems, and reducers. The controller is expected to reach a market size of 1.2 billion yuan in 2020, a proper piece of fat. As the brain of the robot, the action instructions are issued and delivered. In China's hardware part has been basically mastered, but the software aspect is still a certain gap with foreign brands.
In 2015, the scale of 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 have to be improved in terms of intelligence and flexibility. There is a huge room for development in the development of standardized and open controllers. By 2020, the market size of China's industrial robot controllers is expected to reach 1.2 billion yuan, and the compound growth rate in the next five years is about 27%.
The servo system is an important part of industrial automation. It is the necessary way to achieve precise positioning and precise motion in the automation industry, and the joint drive of the robot cannot be separated from the servo system. In recent years, the industrial robots, electronic manufacturing equipment and other industries have expanded rapidly, and their application scale in emerging industries has grown rapidly.
At present, Japanese brands account for half of China's servo system market. Foreign servo companies have a market share of 75% in China, of which Japanese brands account for 50%. However, with the improvement of domestic servo system performance, 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 main types of reducers for industrial robots: RV reducers and harmonic reducers.
With the development of industrial robots in the future, CIC Consulting Industry Research Center predicts that by 2020, the market size of China's industrial robot reducers will exceed 4 billion yuan, and the compound growth rate in the next five years will be about 30%. Despite the strong demand for industrial robot reducers in China, the production capacity of domestic reducers is far behind Japan, the United States and Europe.
On the whole, the industrialization of industrial robots in China still needs to be strengthened. The most important thing is that the core parts market has yet to be broken, because these basic resources will directly affect the upgrading of China's robot industry.
Machine vision is very promisingAs 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 autonomous driving, from virtual reality to automatic object recognition, machine vision can play an important role.
Industry 4.0 is inseparable from intelligent manufacturing, and intelligent manufacturing is inseparable 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 a necessary 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 a new horizon for industrial automation in China.
The application of machine vision on 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 machine vision method, it is possible to quickly and accurately detect whether the pharmaceutical packaging is intact. By setting the image sensor, the image information of the packaged object is obtained, and each medicine or bottle is detected by a preset area parameter. In contrast, the damaged granules or the missing bottles will be detected and passed correctly.
The difference between machine vision and industrial robots is the application scenario. In the environment of industrial robots, the scenes seen by computer vision are relatively simple, but the application scenarios of service robots are much more complicated. Beyond the scene is the precision aspect. In industrial robots, the recognition accuracy of computer vision must be below the millimeter level, including static identification accuracy and dynamic identification accuracy. Static refers to the relative state of the camera or observation object in a static state. The accuracy depends on the resolution of the camera, including whether the edge of the item is clear, and whether the differentiation is clear. At this time, the accuracy can even reach the micron level. The accuracy of the service robot is not very high, and may be above the centimeter level.

Is your battery draining quickly? Does your battery percentage jump?
These are signs of a worn out battery. All lithium batteries, today's
standard battery type in electronics, wear out with time and with use. A
drop in capacity can usually be noticed after six months. After 12
months (~300 charge cycles), it's common that the battery has lost
10-30% of its original capacity. Eventually, the battery will fail to
keep the phone running stable and the phone could shut down in use or in
standby mode.
