When people complain that they work like machines every day, machines can already work like people, even better than people.
Handling, sorting, palletizing, sanding, polishing, cutting, welding, painting, assembly... Industrial robots are almost omnipotent, â€œjust put the right operator in the end of the universal robot and write the correct program into the control box. In theory, it can do anything.â€ A senior industrial robot developer emphasized that the robot does not need to rest, does not squat the boss, does not require overtime pay, does not change jobs, and does not jump off the building.
From Foxconn, a foundry empire with nearly 100,000 employees, to a start-up small business with only a few people, industrial robots have quietly entered the production lines of more and more Chinese manufacturing companies.
The data shows that China is one of the countries with the highest growth rate of robot demand in the world. Last year, the sales volume was 22,600 units, the total number reached 70,000 units, a year-on-year increase of 51%, while the growth rate of countries such as Germany and Germany was below 40%. It is expected that China's industrial robot sales will become the world's number one in 2014.
Japan's FANUC, Germany's KUKA and other companies in China's robot sales have risen more than 100%, many international leading robot manufacturers that have not set up factories in China are brewing in China. At the same time, in the field of domestic industrial robot manufacturing, Shenyang Xinsong, Guangzhou NC and other old-fashioned powerhouses competed with imported brands, and the new recruits such as Zhongxingxing and Lixunda have sprung up. They all saw that under the attack of labor shortage and rising labor costs, the Chinese industrial robot market showed an explosive situation.
People's feelings for the machine are very complicated, there is love and hate. 80 years ago, in the "Modern Times", Chaplin vividly presented the opposition between man and machine. The simple task of the assembly line in the big industrial era made people almost become machines. The machine at that time was synonymous with simplicity.
For more than half a century, mankind has adapted to the convenience brought about by mechanization. From production to life, machines are everywhere.
Now, people and machines will face another confrontation. The emergence of intelligent robots has liberated people from simple, repetitive, single mechanization work, and also occupied the living space of labor workers.
More and more robots enter the production line
At the Shenzhen High-Tech Fair more than a month ago, a handling robot called AGV became the focus of attention. This machine is less than one meter long and looks like a metal suitcase. It runs 60 meters per minute. After installing the double-layer bracket, it only needs to follow the magnetic induction track laid under the foot to easily move the goods from the end of the workshop line. To the other end. The company's sales executives accounted for the client while demonstrating. This standard unmanned van is equivalent to three porters and drivers plus one transporter. If the monthly minimum of 3,500 yuan per person, the monthly salary of the three workers is 10,500 yuan. The application operation of a machine worker, after deducting maintenance costs, can save the enterprise a salary of 12,600 yuan a year. At the same time, it can increase production efficiency to more than 20%. "If calculated by a factory with a monthly output value of 100 million yuan, this is equivalent to a benefit space of 20 million yuan." It is understood that a large-scale foundry factory in Shenzhen has used this machine porter on the assembly line.
Shenzhen Leibo Technology was put into use in a new factory building in April 2012. The two orange-red small robots in the workshop window are working closely together, one for the mouse switch and the other for the film. Every few tens of seconds, the manipulator on the right side twists his body and bends it to 90 degrees. It touches the robot on the left side in the air and the docking is completed.
Laibo Technology is a company that produces wireless peripherals such as mouse and keyboard. In 2011, Leibai Technology made a huge adventure and purchased 75 industrial robots from Swiss robot manufacturer ABB. Today, the new plant of Leibo Technology is significantly different from the factories of thousands of other electronics companies in Shenzhen: the main characters in the production line of Leibai Technology are not rows of workers, but a new series of robotic arms, each production line. There are only a few workers left.
The founder of Raytheon Technology, Zeng Haoxue, who came from automation, knows that robots are several times more efficient than manual ones. For example, the robot's tact time on the USB socket production line is only 3 seconds, and the production efficiency is 60% higher than the manual. The production of two sets of workpieces can be carried out simultaneously, saving more than 10 labor. The recycling cost of these equipment is only two years, much cheaper than the labor cost.
What makes Raybow technology even more satisfying is that ABB's robotic manipulators work extremely accurately. "In the past, a tiny piece of iron on the mouse required workers to bend 90 degrees with a hand tool. Not only was it hard and inefficient, but it was broken when accidentally; the original automation equipment could not achieve this precision; but now these robots Can be completed in one time, with a success rate of almost 100%."
The rewards of using robots on a large scale are obvious. Through the natural loss of employees, the company has â€œslimmedâ€ the company by two-thirds. The current staff size is maintained at around 1,000, while the per capita productivity has increased four-fold. More importantly, because the robot is more stable in repeated production, the quality of the product is greatly improved, which is the guarantee for the company to obtain higher profits.
The total number of domestic industrial robots exceeds 100,000 units
Internationally, the level of automation in a country is usually measured by the density of manufacturing robots, which refers to the number of multi-functional robots owned by each 10,000 employed workers. According to data from the International Federation of Robotics (IFR), Chinaâ€™s figure for 2011 is 21, the international average is 55, and Chinaâ€™s 339 and Japanâ€™s 347 are still far behind. However, China's growth rate is very fast. From the perspective of installed capacity, from 1999 to 2008, the installed capacity of industrial robots in China has increased by more than 20% every year, from 550 in 1999 to more than 30,000 in 2008. . Even in 2009, when the global economy was in a depression, sales of Chinese industrial robots were on the rise. In 2010, China's installed capacity was 52,290 units, and in 2011 it rose to 74,317 units, achieving an annual growth of 42%. In terms of sales, China's robot sales increased from 14,978 in 2010 to 22,577 in 2011, an annual increase of more than 50%. According to industry insiders, at present, the actual domestic industrial robots should exceed 100,000 units. IFR expects China to become the world's largest industrial robot market.
Dr. Zhang Hui, Technical Director of ABB China Robotics R&D Center, believes that the large-scale application of robots instead of artificial fields is nothing more than the following three situations: First, for industries with extremely high precision and speed, robots can greatly improve production efficiency. Product rate; secondly, the work environment is harmful to workers' health. Robots can replace labor to complete those jobs that are detrimental to health; finally, countries or fields with extremely high labor costs, using robots can reduce labor costs.
Mr. Chen is a research and development personnel of an industrial robot manufacturing enterprise in Shenyang. He told reporters that although compared with foreign countries, China's industrial robot industry started late; but 20 years ago, the gap between China and the international level was not big, and later China was cheap. The labor costs have hindered the cultivation of the domestic industrial robot market. â€œWho is so cheap to spend so much money on machines?â€ He believes that in the next 20 years, China and Japan, Germany, Sweden and other countries will be in robot manufacturing. The gap in standards is getting bigger and bigger.
