All the factory’s processes are operated by computer-controlled robots, computer numerical control machining equipment, unmanned transport trucks and automated warehouse equipment. The technical staff just sits at the computer and monitors through a central control system.
At the workshop of Changying Precision Technology Company in Dongguan, known as the “world factory”, which manufactures cell phone modules, 60 robot arms at 10 production lines are polishing the modules day and night. Each line has an automatic belt and three workers who are just responsible for checking lines and monitoring.
A few months ago, it required 650 workers to finish this process. A robot arm can replace six to eight workers, now there are 60 workers and the number will be reduced to 20 in the future. Data shows that since the robots came to the factory, the defect rate of products has dropped from over 25 percent to less than 5 percent and the production capacity increased from 8,000 monthly pieces per person to 21,000 pieces.
