With the advent of Industry 4.0, this prediction is gradually becoming a reality. In the huge workshop of SAIC-GM's Jinqiao plant, there are only more than 10 workers who are actually paid. They manage 386 robots and cooperate with robots to produce 80 Cadillacs every day. Jingdong "Asia One" unmanned warehouse is at the leading level in the industry in terms of order processing capabilities and comprehensive matching capabilities of automation equipment. Midea's central air conditioner has core components and fully automated assembly lines. The number of people on the production line has dropped by 50%, the human-machine ratio has reached over 4%, and the product qualification rate has reached 99.9%. The development of artificial intelligence has brought many changes to people's lives. While the efficiency and operating standards of unmanned factories have been rapidly improved, they have freed the hands of workers and given people the opportunity to engage in non-repetitive mechanical labor. Unmanned, intelligent and automated have become an unstoppable development trend of modern manufacturing. Therefore, the unmanned chemical factory model must be a major development trend in the future. China’s "machine substitution" is not a slogan. In the future, traditional manufacturing will actively transform and continue to develop in the direction of Internet intelligent manufacturing, and can achieve more Great brilliance!
