Driven by the wave of new technological innovations, such as the new generation of information technology, artificial intelligence, and advanced manufacturing technology, the global manufacturing industry is undergoing major changes in organizational mode, production mode, and service mode. The innovative mode of intelligent manufacturing, represented by Germany's "industry 4.0", is favored by all countries in the world. The rapid promotion of intelligent manufacturing technology provides a huge market opportunity for the development of industrial robot industry. As a rising star of the industrial robot family, collaborative robots have seen their innovative application models emerge and their application scenarios become increasingly diversified in recent years under the continuous attention of major manufacturers and the capital market. , however, the process of rapid rise in new market, opportunities and challenges often becomes the norm, especially in the face of the current driven by innovation as the core, with 5 g communications, big data and cloud computing, smart Internet of things, such as artificial intelligence for technical support, promote to cross-border integration between between different industries, industry in the development of "intelligent economy" new era of collaborative robot how to grasp the "smart" economic development opportunities, fast accurate market positioning, promote the industrialization process, worth collaborative robot manufacturers deep thinking and exploration.
I. definition and classification of cooperative robots
Cooperative robot refers to the intelligent robot with automatic control and programming ability, and can interact with human beings in the same workspace in a close distance, cooperative work. Compared with traditional industrial robots, cooperative robots break the limitation that can only be used in industrial scenes. With the advantages of low self-weight, high flexibility, easy programming, rapid configuration and small limitation of operation space, cooperative robots also have a broad application prospect in the service industry scenes such as medical treatment, education and training, and new retail.
From the point of view of the mainstream collaborative robot product classification, the first is according to the structure classification, mainly including the two-arm robot and the one-arm robot. Among them, the dual-arm robot has a relatively wide operating range and can adapt to relatively complex work scenarios, but its production and application costs are relatively high. In particular, from the perspective of the main application scenarios of cooperative robots, the main industries are 3C electronics, household appliances, food and beverage production lines with intensive point positions, high production flexibility requirements, single operation and high repetitive action frequency. The applicability and application cost performance of dual-arm robots are relatively low. One-arm robot has great advantages in production and application cost and placement space. Second, according to the load capacity classification of cooperative robots, it mainly includes three categories: the payload < 5kg, the payload ≤10kg and the payload > 10kg.
From the point of view of the industrial chain, the industrial chain of cooperative robot is basically the same as that of industrial robot, which mainly includes four links: core parts, ontology manufacturing, system integration and downstream application.
Among them in terms of core parts, due to the collaborative robot in the process of operation and artificial contact closely, the operation of the safety guarantee for collaborative robot accuracy, operating flexibility, and zero torque control and collision detection technology put forward higher requirements, so the collaborative robot core parts slightly different product types and industrial robots. It mainly includes hollow dc motor, safety controller, torque sensor, reducer, brake, encoder and so on.
The process of ontology manufacturing mainly refers to the manufacturing of robot body and robot arm.
System integration mainly refers to the integrated application of robot body with spraying, welding, loading and unloading, assembly and other production links. Suppliers of comprehensive solutions are mainly ontology manufacturers. Downstream applications mainly include 3C electronics, automobiles, home appliances, mechanical equipment, logistics, food and beverage, commercial services and other industries.
Ii. Overview of global cooperative robot development
Since 2016, with the support of technologies such as big data and cloud computing, the artificial intelligence industry has started to break out, helping the industrial robot industry to open a new era of 2.0. Man-machine collaboration and man-machine integration have become the mainstream trend of the market, constantly pushing collaborative robots to the forefront of the market. Therefore, the global sales volume of cooperative robots showed an explosive growth in 2016. The global sales volume of cooperative robots exceeded 10,000 units that year, with a year-on-year growth of more than 90%. At the same time, as most of the cooperative robot manufacturers are in the stages of product polishing, trial and error, solution optimization and technical route selection, rapid iteration of new products and new models forces the industry to accelerate into the shuffling period of "survival of the fittest". From the perspective of global sales volume of cooperative robots from 2017 to 2019, the sales growth of the cooperative robot market tends to slow down. In 2019, the global sales volume is 30,000, with a year-on-year growth of 36.4%.
In terms of the global sales volume of cooperative robots, the global sales volume of cooperative robots reached 5 billion yuan in 2019, with a year-on-year growth of 31.6%.
From the perspective of the global competition pattern of cooperative robots, u-ao robot is the world's leading cooperative robot enterprise. According to the company's public data, the global cumulative sales volume of u-ao cooperative robots has exceeded 37,000, ranking the first place in the global market share of cooperative robots. At the same time, with the strong entry of leading traditional industrial robot enterprises represented by ABB, yaskawa and fanuc, the global market competition has become increasingly fierce.
Iii. Overview of the development of cooperative robots in China
On the one hand, with the decrease of the working-age population and the increase of labor cost in China, there is an increasingly significant trend for manufacturers to use robots to replace low-end labor. Compared with traditional industrial robots, cooperative robots have prominent advantages of low cost, light weight and high safety performance. Therefore, the accelerated adjustment of China's labor structure will further drive the application demand of cooperative robots in the market. , on the other hand, under the background of the transformation and upgrading of industrial structure in our country, the traditional manufacturing industry and electronic technology, automation technology, the development trend of information fusion technology has become increasingly apparent, constantly leading manufacturing companies for intelligent manufacturing, flexible manufacturing, networked collaborative manufacturing, etc. The application of advanced manufacturing technology, from the point of technology trends, highly collaborative robot fit manufacturing enterprise demand for the transformation of man-machine coordinated, flexible manufacturing, market development potential is tremendous. In 2019, the scale of China's cooperative robot market reached 1.3 billion yuan, with a year-on-year growth of 42.9%. Under the overall "cold" situation of the industrial robot market, the development trend of countertrend growth was maintained.
From the perspective of China's cooperative robot market structure, in recent years, cooperative robot enterprises, such as oubo, jieka, dazu, luoshi, daming and xinsong, have gradually broken the market monopoly of foreign brands by constantly strengthening technology and product innovation, and their market share in China's cooperative robot continues to grow.
