In recent years, under the influence of factors such as increasing labor productivity and accelerating technological innovation, the global manufacturing landscape is changing. The global increase in labor costs and the acceleration of the transformation and upgrading of the manufacturing industry have made all countries step up the implementation of smart manufacturing and automated production plans. The deep integration of a new generation of information technology and manufacturing is triggering far-reaching industrial changes, forming new production methods, industrial forms, business models and economic growth points. In terms of manufacturing methods, intelligent manufacturing based on cyber-physical systems, such as smart equipment and smart factories, is leading new changes. Industrial robots, high-end CNC machine tools and other equipment, as carriers of smart manufacturing and digital factories, have become important driving forces for economic growth in various countries.
In the context of Industry 4.0, countries and regions represented by the United States, Japan, and Germany have attached great importance to promoting the development of the robotics industry, and have achieved high industry concentration and market share by virtue of their technological first-mover advantages. In recent years, the global industrial robot industry has maintained rapid development. According to IFR statistics, the global sales of industrial robots will reach 376,000 units in 2020. Although it has fallen from the high point in 2018, the overall trend is still increasing.
