"Smart Eyes" Tracking Precision Intelligent Manufacturing
——【ATINY】 seizes the beach in industrial intelligent manufacturing
Our reporter Yu Jingwen
In daily life, people often see that welders wear protective equipment and perform welding work between "electric flints". At this time, passing pedestrians usually choose to stay away.
The main reason is that the smoke, arc, electromagnetic, splash, poisonous gas, etc. formed during the welding process will cause a certain degree of harm to the human body.
In addition, welders are also faced with many dangerous factors such as electric shock, poisoning, fire, explosion, etc.
during the welding operation, and the types of welders are therefore listed as high-risk industries.
Today, with the rapid development of industrial automation, welders are active in more professional subdivisions, serving high-precision equipment and instruments,
and part of the daily work can be completed through assembly lines.
In 2016, as Alpha Go defeated the top human players, the wheel of history also began to enter the time of artificial intelligence.
The word difference between "manufacturing" and "intelligent manufacturing" has made it difficult for many domestic welding factories to undergo transformation and upgrading.
The work of welders requires the cooperation between eye-brain-hands.
If you want to realize unmanned intelligent operation, you need to break the technical bottleneck, so that the robot can see, think, and act like a human.
This is precisely Industry 4.0.
The core: through the "sensing-decision-execution" approach, the intelligent and informatization upgrade of the entire life cycle process of the industrial chain.
"At that time in China, most of the intelligent transformation factories used foreign technology and equipment for weld tracking and weld recognition.
The equipment was not only expensive, but also because of the'unacceptable water and soil', the production line was stagnant."
After investigating many factories in the south, Ling Qing, general manager of【ATINY】 , outlined the company's development direction in the past five years-the field of intelligent welding. Nowadays, 【ATINY】 laser displacement sensor technology has achieved "two-dimensional" success in technical and commercial applications in the field of intelligent welding.
After solving the "stuck-neck" technical dilemma, 【ATINY】 will move towards a broader market for smart sensors.
In 2012, Ling Qing participated in a domestic exhibition with tracking technology.
"Five Resistance Technology" Solve the Difficulties of Intelligent Welding
"Young man, can you use your technology to weld these two steel plates."
Not long after the launch, a visitor came to the booth and asked Ling Qing to feel that "a gap should not be difficult."
Soon, the steel plate welding was completed, and the visitor immediately sought cooperation to purchase the tracking product.
In word of mouth, Ling Qing gained the "first pot of gold" since its founding, and it was also this "mistyped collision" that made Ling Qing realize that due to technology,
domestic enterprises that can truly engage in the research and development of intelligent welding technology Very few,
and the factory can only buy imported equipment, but the price is ridiculously expensive.
Under the "blue ocean", Ling Qing decided to set up the【ATINY】 in Haidian Pioneer Park and quickly set up a core technical team.
With the three technologies of tracking, high-speed processing board and high-precision detection, it launched at the end of 2013.
The first generation laser welding seam tracking system of 【ATINY】 .
The system has the characteristics of small size and low power consumption, but the price is only 1/4 of the price of foreign products.
Since the end of 2015, this system has ranked first in the domestic market share in the industry, breaking the technological monopoly of foreign companies.
The laser weld tracker is installed on the front end of the robotic arm to replace the human eye to measure the weld, guide and control the positioning of the welding torch.
The industrial robot starts a wonderful welding "dance" at the welding site, and continuously adjusts it in real time with the input of sensor data Your own route is always high and sometimes low, sometimes fast and sometimes slow.
During the welding process, the tracker is not affected by the solder joints, splashed fire and smoke, and can still be accurately positioned and draw a beautiful arc,
effectively ensuring production efficiency and product quality.
Ling Qing told reporters that at present, there are not many domestic companies engaged in the research and development of intelligent welding products,
but they can simultaneously have the five "anti-" capabilities of anti-arc, anti-smoke, anti-splash, anti-spot welding, and anti-electromagnetic interference.
【ATINY】 can do it, and the tracking accuracy can reach 0.04 mm, and the response time can reach 1 millisecond,
which has reached or exceeded the technical parameters of similar foreign products.
According to Ling Qing, at present,
the laser displacement sensor and visual seam tracker independently developed by 【ATINY】 have been adapted to more than 40 industrial robot brands,
establishing an intelligent ecosystem in the global welding field.
He emphasized that “this kind of adaptation ensures the integration of industrial robots and displacement sensors, that is,
the dialogue between the'brain' and the'eyes', and the unmanned operation of the welding process can be realized without any on-site customization of the docking and debugging."
Mass production of self-developed and self-made high-precision sensors into the market
After great success in the field of intelligent welding, Ling Qing decided to improve the accuracy of the sensor and make a general-purpose laser displacement sensor.
Once this type of sensor is successfully developed, the built-in highly integrated digital signal processor can not only be used for displacement, distance and position measurement,
but also not affected by the material, color and emission light source of the surface object, and it has a wide range of applications.
"The application market for this kind of general-purpose laser displacement sensor is very large, but at present, the domestic market share of foreign brands has reached 99.87%."
Ling Qing also gave an example,
"During the assembly process of mobile phones, due to high precision Requirements are limited, and many steps need to be completed by special robots instead of humans.
For example, the robot arm needs to glue a glass panel to the fuselage, not only to bypass the tiny holes, but also to apply the glue thin enough,
which requires the operator It can only be implemented if it is visible. Precise scanning of the laser displacement sensor in advance can solve this problem."
In 2015, the intelligent welding business of【ATINY】 showed a steady upward trend, and the company began to focus on the research and development of general-purpose laser displacement sensors. "The technology research and development progress of the sensor itself is very fast, the accuracy has reached 5 microns, and the supply chain for mass production has also been set up.
When【ATINY】 decided to open up the market, the calibration table required for mass production became a big problem.
"The calibration table can be regarded as a ruler or a reference object. With it, the time for producing sensors will be shortened from a week for manual calibration to a few hours.
Only the speed has been qualitatively improved, and mass production To become a reality."
And such basic automation equipment can only rely on foreign imports.
It is at the critical moment when the factory is ready to start work, and Creative Intelligent Control is "stuck" and is stuck in a difficult-to-buy situation with money.
"Let's make it ourselves!"
In 2019, 【ATINY】 Laser Displacement Sensor entered the stable mass production stage and officially entered the market.
Nowadays, the self-developed calibration platform of 【ATINY】 is the third generation, with more and more complete functions and faster and faster.
At the Jinan factory of 【ATINY】 , the output of general-purpose laser displacement sensors has reached 2,400 units per year.
At present,【ATINY】 has established five subsidiaries in Jiaxing, Shenzhen, Chengdu, Jinan, and Changsha,
which are "four arrows" in technology research and development, marketing, after-sales, and corporate internal management.
"To take the road of core technology innovation is very difficult and full of challenges. However, in order to achieve the goal of【ATINY】 ， we must do the most core, difficult, and high-value link." In the second five years, 【ATINY】 will plan The direction is set in the field of smart sensors, extending to a wider field.
