The watch industry is one of Liaoning's traditional industries. At present, Liaoning is accelerating the transformation and upgrading of traditional industries and promoting the rapid development of high-tech manufacturing.
Front desk reporter Yang Xue: This is the intelligent R&D and manufacturing platform for the movements of millions of high-end mechanical watches in Dandong, Liaoning. Now the masters are assembling the movements of double tourbillon watches. Maneuver is the heart of a mechanical watch. The movement of an ordinary mechanical watch has a large travel time error due to the influence of spring tightness, gravity and other factors. The tourbillon watch is equipped with a "rotary escapement speed regulating device", that is, a tourbillon speed regulator, which can greatly reduce the impact of gravity and other factors, and has higher travel accuracy.
The double tourbillon represents the highest level of mechanical watch manufacturing technology. At present, the highest level in the world is that the double tourbillon is at 5 o'clock and 7 o'clock. After many years of technical research, engineers from Dandong, an enterprise, independently developed the first domestic 5-point and 7-point double torque flywheel engine.
What we see at the moment is the model of this machine. You see, the double tourbillon is located at 5 o'clock and 7 o'clock, just like the big eyes of an owl, smart and beautiful.
The travel time error between square inches is less than 10 seconds
However, for ingenuity, the real skill contest lies in the subtlety. As you can see, this small part, called the escapement fork, is the escapement speed regulating device in the heart of the double toggle flying machine, and is one of the important parts that determine the travel accuracy of the watch.
This is a model magnified by 10 times. It can be seen that the process is very complicated.
In the past, the production of such a escapement fork had to go through multiple processes such as blanking and punching. Because the parts were very small and irregular in shape, the operation was very difficult. A master researched and produced the one-time forming mold of the escapement fork, which made the travel accuracy of the double tourbillon flywheel center reach an error of 10 seconds.
The combined application of high-precision equipment has a processing accuracy of only one twentieth of that of hair
However, a double tourbillon center is generally composed of more than 200 such tiny parts. Only when each part is infinitely close to the design accuracy can the final operation of the whole machine center be guaranteed to be perfect. To this end, this smart R&D and manufacturing platform has invested a variety of high-end equipment for joint R&D and application.
This is a high precision and high-speed machining center, with 72 cutters, which can complete the multi sequence machining of the original process at one time.
This equipment is an automatic flexible intelligent manufacturing unit, which has the functions of chip identification and high-precision positioning, and can realize intelligent, flexible and accurate feeding of various materials. The joint research and development of a variety of equipment can shorten the 70 day period for the trial production and development of new products to less than 10 days. At the same time, the processing accuracy is also improved from 0.02mm to 0.003mm, which is equivalent to one twentieth of the diameter of human hair.
High end intelligent manufacturing produces 1 million high-end machines annually
Key core technologies have been constantly tackled, and high-end equipment has been jointly applied, from traditional production to high-end intelligent manufacturing. Now, the traditional watch industry is accelerating its transformation and upgrading. In Dandong, an intelligent R&D and manufacturing platform for mobile phones, there are now 7 series, 30 basic mobile phones and more than 300 kinds of mobile phones. Every year, the platform develops 4 new products and launches 20 technologically improved products on average, and 1 million high-end computers go to the world from here.
The "new quality" password that enables robots to do thousands of things
As an old industrial base, Liaoning's traditional industries are accelerating transformation and upgrading, while emerging industries are also booming. During the investigation, the reporter came to a robot manufacturing enterprise in Shenyang to explore the "new quality" password of enabling thousands of industries with robots.
This intelligent robot "calligrapher" who is splashing ink can be so dexterous because of the installation of a newly developed intelligent interaction system. It is like having a flexible brain, which can independently analyze human voice and intonation. Through AI big model technology, it can accurately analyze the feelings or expectations of the voice initiator, and accurately present matching calligraphy works.
Han Tianwen, President of Xinsong Robot Artificial Intelligence Research Institute: Robot intelligence has always been our goal. This natural language interaction mode is a subversive change. For customers, from the perspective of using robots, there is no longer such a big professional barrier.
With the breakthrough of key core technologies, the functions and adaptability of robots continue to be optimized and improved. This robot is equipped with a self-developed multi-sensor integrated navigation system, which is currently used in a variety of complex scenes such as factory parks, airports, ports, etc.
Yu Jian, Deputy Director of the Mechanical Department of the General Equipment Business Department of Shinsong Robot Mobile Robot BG: It can realize rapid modeling and effective positioning in various complex environments on and off the field, and can also be applied to various complex weather and complex roads, effectively identifying various dynamic or static obstacles.
At the same time as enterprises strengthen scientific research, Shenyang also relies on the national key laboratory, facing the major national needs, and has made breakthroughs in the common key technologies and platform development of marine robots, aerospace robots, and land mobile robots, serving the national deep-sea exploration, aerospace engineering, emergency rescue and other fields.
Yu Haibo, head of the Science and Technology Department of Shenyang Institute of Automation, Chinese Academy of Sciences: Facing the world's leading edge of science and technology, we have made layout in such aspects as sensor computer control integrated robot system, life fusion robot and humanoid robot, and carried out systematic scientific research. At present, a number of original scientific research achievements have been made in basic theories such as life like robots and brain machine enhanced robots.
At present, there are 15 backbone robot enterprises in Shenyang, and a number of national public platforms, such as the National Robot Innovation Center, the Robotics and Intelligent Manufacturing Innovation Institute of the Chinese Academy of Sciences, have been established. In order to promote the high-quality development of the robot industry, Shenyang has drawn a map of the robot industry chain.
Mu Na, Director of the Equipment Department of Shenyang Municipal Bureau of Industry and Information Technology, Liaoning Province: Focusing on improving the industrial support capacity, support research and enterprise collaborative innovation, and constantly strengthen the strengths and weaknesses. At the same time, we will make good use of policy funds to promote innovation, breakthrough, promotion and application of major technical equipment, and accelerate the construction of the robot industry ecosystem.
