CIMS-led manufacturing development trend of five technological transformations (4)
The robot does not replace manual labor in a simple sense, but a kind of anthropomorphic electromechanical device that combines human characteristics and machine characteristics. It has a quick response and analysis and judgment ability to the environment, and the machine can be used for a long time. The ability to work continuously, with high precision and resistance to harsh environments, in a sense, is also a product of the evolutionary process of the machine, an important production and service equipment in the industry, and an indispensable automation device in the field of advanced manufacturing technology.

In China, the real use of industrial robots has been around for 20 years now. Starting from the "seventh five-year" scientific and technological breakthroughs in the 1980s, with the support of the state, the design and manufacturing technology of robotic manipulators, control system hardware and Software design technology Kinematics and trajectory planning technology, the production of some key components of the robot, the development of painting, arc welding, spot welding, assembly, handling and other robots, some of which have achieved scale applications.
Among the many manufacturing sectors, the most widely used field of industrial robots is also the automotive and auto parts manufacturing industry. In 2005, the demand for industrial robots in the automotive and auto parts manufacturing industry in the Americas accounted for 61% of the demand for industrial robots in all industries in the region; the proportion in the Asian region also reached 33%, ranking first in various industries.
Although industrial robots are also the most widely used in China's automobile manufacturing industry, due to the labor cost factor, there is still a gap between the use of industrial robots and foreign counterparts. However, there are some application examples, such as the Beijing Benz-Daimler Chrysler Automobile Factory, which uses a large number of robotics in the production of the domestic Chrysler 300C.
In addition to the automobile manufacturing industry, China has more applications for robots in IT and information appliances. SVA and NEC and Beijing BOE have used hundreds of MOTOMAN robots for dust-free handling of large-size LCD glass.
In recent years, in order to ensure that products have strong competitiveness in the market, large and medium-sized state-owned enterprises in China's manufacturing industry have been continuously increasing the procurement of industrial robots for technological transformation. Some private enterprises have gradually realized the advantages of using industrial robots to help produce high-quality products at reasonable prices, and the adoption of industrial robots has gradually increased.
At present, China's industrial robot technology and its engineering application level still have a certain distance compared with foreign countries. For example, the reliability is lower than that of foreign products, the robot application engineering starts late, the application field is narrow, and the production line system technology has a gap with foreign countries. . The above reasons are mainly due to the lack of the formation of the robot industry. At present, the production of robots in China is aimed at users. “One customer, one redesignâ€, with many varieties and specifications, small batch size, low generalization of parts, long lead time and cost. Not low, and the quality and reliability are unstable. Therefore, it is urgent to solve the key technologies in the early stage of industrialization, comprehensively plan products, do a good job in serialization, generalization, and modular design, and actively promote the industrialization process.
Green manufacturing
In the 1990s, the concept of green manufacturing was introduced internationally, also known as cleaner production and environmentally oriented manufacturing. It is a modern manufacturing model that takes into account the environmental impact and resource efficiency under the premise of ensuring the function, quality and cost of the product, so that the product does not produce environmental pollution or environmental pollution during the life cycle of the product from design, manufacture, use to end-of-life. Minimized, in line with environmental protection requirements, harmless or less harmful to the ecological environment, the highest resource utilization and lowest energy consumption.
Green manufacturing is essentially a manifestation of the sustainable development strategy of human society in modern manufacturing. In green manufacturing, the goal is no longer limited to only fulfilling the functions of the product and meeting the needs of users, but must meet the requirements of environmental protection and energy conservation in terms of production and consumption.
Green manufacturing is vital to the sustainable development of the future manufacturing industry, and has attracted the attention of global manufacturing industry. It has become the main content of advanced manufacturing technology and research projects that countries have prioritized and supported. At present, the world has carried out a lot of research and development work on green product design, green clean production, recycling and remanufacturing of waste products, and achieved initial results. In the early 1990s, the United States established the National Remanufacturing and Resource Recovery Center, as well as the Remanufacturing Institute and the Remanufacturing Industry Association. Europe has also adopted relevant laws and regulations to support remanufacturing. Fuji Xerox, Canon and other companies in Japan have established recycling points for discarded copiers.
