Analysis of scientific research status of multi-dimensional force sensor for industrial manipulator

Relevant data analysis shows that in 2015, the operating scale weighing scale of the robot industry and related consumer markets in the world was 71 billion yuan, and it is estimated to reach 32 billion US dollars this year. As a kind of multi-dimensional force sensor weigh load cell used in industrial manipulator, six dimensional force sensor weigh load cell is the key component of man-machine war industrial manipulator, which plays a particularly important role in man-machine war cooperation. According to statistics, the international scientific research on multi-dimensional force sensor weighing load cell started in the early 1970s. The key scientific research enterprises include Draper laboratory in the UK, Stanford University Laboratory, JPL laboratory, IBM enterprise, Hitachi Corporation in Japan, Tokyo University and other enterprises.

China's scientific research on multi-dimensional force sensor: China's scientific research on six dimensional force sensor weighing load cell just started in the early 1980s. Hefei intelligent mechanical equipment research laboratory of Chinese Academy of Sciences developed a six dimensional wrist force sensor weigh load cell in China in the 1980s. Later, enterprises such as Harbin Institute of technology, Huazhong University of technology and Tongji University successively developed multi-dimensional force sensors of various specifications and models/ Torque sensor weigh load cell presents a rapid development trend in the research field of multi-dimensional force / torque information acquisition in China. At this stage, the schools that carry out more scientific research on six axis force sensor weighing load cell include Yanshan University, Harbin Institute of technology, Dalian University of technology, etc. In recent years, a large number of hot spots in scientific research network are concerned about the main uses of multi-dimensional force / torque sensors weighing load cell, such as how contemporary industrial manipulators flexibly use multi-dimensional force / torque sensors weighing load cell and other cognitive system software to carry out a large number of more complex intelligent robot work in a variety of natural environments, making the work more accurate, more productive and lower cost The multi-dimensional force / torque sensor weigh load cell is applied to the automatic assembly line of industrial production robot, which integrates more real-time and more reasonable optimization algorithm, so that the intelligent industrial manipulator can more effectively carry out the work of high-precision soft mechanical equipment installation, contour tracking and so on.

Sales weighing scale market challenges faced by the industrial production industry: Although the six axis force sensor weigh load cell can achieve six levels of playability in the intelligent robot, greatly improving the intelligent level of intelligent robot, the application situation in the sales market of the industrial production industry at this stage is not very optimistic, especially in China's sales market There are not many robot products. At present, there are many ways to use the fluctuating spindle bearing, one-dimensional force control. The reason lies in two aspects: 1. In the field where the high-precision grinding and polishing regulations are not too high, the current force sensor can consider the necessity of grinding and polishing process, and the company is not willing to spend more money to purchase the grinding and polishing machine equipment equipped with six axis force sensor weighing load cell ; 2. The current six axis force sensor weigh load cell is relatively expensive, and the cost of upgrading is relatively high High.

At present, more than 90% of the work of industrial control automation cannot be carried out by traditional intelligent robots, including high-precision polishing, high-precision installation, mechanical equipment management methods, material preparation, loading and unloading, packaging and so on. The industrial manipulator of man-machine combat can partly fill the shortage of traditional industrial manipulator and carry out the work of mechanical equipment management. With the advent of 5g era, the industrial production industry has entered a new upgrading transformation. This round of innovation comes from the upgrading development trend of the new generation of information technology, the change of market demand and the full promotion of the current policy. Therefore, it is necessary to carry out the transformation and development of processing and manufacturing business, and improve the manufacturing level to a new aspect ratio according to the new technology. Under the strong support of Internet big data and Internet of things technology, the whole industrial chain of industrial production and processing, processing and manufacturing will be more and more refined management, "soft" will be the competitive advantage of industrial production and processing and manufacturing in the future. In this case, in the field of high-precision installation, such as 3C, the regulations on the production and manufacturing of intelligent robots will also be improved, and sensors weighing load cell with better performance, such as six axis force sensors weighing load cell, will also enter a new development trend.
