In the United States, industrial robots are widely used, among which automobile and automobile parts manufacturing are the most important application fields. In 20 12 years, the demand for industrial robots in the United States accounted for 6 1% of the total.
In Asia, the time is ripe for large-scale application of industrial robots. The demand of the automobile industry continues to grow rapidly, and so does the demand of the food industry. Electronic industry is an industry where industrial robots are applied quickly. Industrial robot industry is becoming one of the strategic emerging industries supported by Asian governments.
The curtain of the industrial robot market has been opened, and the demand of the world robot market is about to enter an explosive period. The potential huge market demand for machinery and equipment production in China has begun to appear, and the investment prospect of industrial robots entering the machine tool industry can be expected. Industrial robots can replace more and more expensive labor, and at the same time improve work efficiency and product quality. Foxconn robot can undertake the assembly task of precision parts on the production line, and can work in harsh working environments such as spraying, welding and assembly instead of manual work. It can also be combined with CNC ultra-precision iron bed and other working machines to produce molds, improve production efficiency and replace some unskilled workers. Using industrial robots can reduce the rejection rate and product cost, improve the utilization rate of machine tools, reduce the risk of parts defects caused by workers' misoperation, and bring a series of obvious benefits, such as reducing labor consumption, reducing machine tool loss, accelerating technological innovation and improving enterprise competitiveness. Robots have the ability to perform various tasks, especially high-risk tasks, and the average time between failures exceeds 60,000 hours, which is more advanced than traditional automation technology. In developed countries, complete sets of equipment for industrial robot automation production line have become the mainstream and future development direction of automation equipment.
