Entering TJASSET, located in Tianjin Zhigu, the world's leading and China's first flexible intelligent assembly system for body door covers catches the eye. Only two robots "clear division of labor", smoothly complete the car body parts, bolt picking, installation and tightening operations, the production beat is only 51 seconds/car, and completely replace manual work, intelligent automation rate reached 100%. Seemingly easy behind the "big wisdom", the system is composed of machine vision, flexible positioning unit, 5G communication and other dozens of "innovative technologies".

"We take innovation as a consistent strategic development fulcrum." Li Hao, general manager of TJASSET, said, "This' domestic first 'confirms the innovation matrix effect of the TJASSET team, and the business agglomeration of various sectors gives enterprises unlimited power of intelligent manufacturing."

Machine vision allows the system to "see six ways"

In the absence of human participation, machine vision is the best "eye".

In 2019, "TJASSET" introduced the "Industrial online Measurement Technology" after 20 years of research by the State Key Laboratory of Precision Testing Technology and Instruments of Tianjin University, and applied it to the body door cover assembly for the first time.

"This technology enables precise positioning of the body, doors, door hinge mounting holes and precise measurement of the body door frame." Dong Hao, deputy general manager of TJASSET, said, "By analyzing the measurement results, the best assembly position is calculated by using the technology of break and surface difference matching, and the door is accurately positioned and assembled."

The machine vision measurement range is large, flexible, high precision, and in terms of quality control, the assembly data required for each body in white is feed-back to the big data acquisition system, and the fluctuation trend of data is analyzed through the cloud platform to provide data support for the realization of process monitoring and optimization. The pass rate reaches more than 99%, which greatly improves the production efficiency.

Dong Hao said: "The application of Tianjin University's scientific research results makes TJASSET like a fish in water, in the deep integration, we are now entering the engine, high-speed rail, coding recognition and other industries, and continue to expand the 'TJASSET visual map'."

Flexible positioning unit makes the system "smart"

Most of the domestic automobile manufacturing workshops adopt the mode of "one model and one production line", and the flexible positioning unit can be compatible with the installation procedures of various models through its own "deformation".

As early as 2010, "TJASSET" set up a research and development team of flexible positioning unit, focusing on the research and development of flexible manufacturing solutions for body. Every year, the company will put more than 5 million yuan into the research and development of technology, for the update of equipment, the upgrade of knowledge of members, and the trial and error testing of new technologies; Regularly organize team members to learn and communicate with upstream industries to achieve seamless matching of flexible positioning units and suppliers.

Today, the team has more than 20 invention patents in the field of engineering, to achieve the autonomous control of flexible technology, and implant it into the controller of each flexible positioning unit, so that users with zero experience can easily adjust the product freedom, range of motion and running speed, the number of control axes and other data, "steel" has "flexibility", can meet the customized needs of automobile manufacturing.

After years of technical cultivation, in 2016, the flexible positioning unit produced by "TJASSET" was used in the intelligent manufacturing comprehensive standardization and new mode application project identified by the Ministry of Industry and Information Technology, and quickly opened the market, less than three years, only the contract amount of the flexible positioning unit product exceeded 25 million yuan.

5G communication makes the system "blood flow"

"The first set of flexible intelligent assembly system for the body door cover in China embodies a large number of 'smart cells', and 5G communication is like fresh blood, leading the cells to' become active '," said Wu Xiaoming, deputy general manager of TJASSET.

The phenomenon of WIFI, Bluetooth, 4G and other network transmission methods is widespread in semi-automated automobile assembly and manufacturing production lines, and it is difficult to form an ideal state of "pushing to one place". The first flexible intelligent assembly system for body door cover in China uses 5G communication mode, enables machine vision and flexible positioning unit, and realizes the intelligent assembly of a car with four doors and two covers in 51 seconds. In addition, real-time data such as the number of work orders, production beats, visual inspection, and torque wrenches obtained by 5G networked devices are presented on the industrial big data platform independently developed by Tianjin Fuzhen to provide customers with online services such as remote operation and maintenance and predictive operation and maintenance.

As one of the first national high-tech enterprises specializing in providing intelligent manufacturing equipment and system integration solutions for the automotive industry, in June this year, "TJASSET" signed a cooperation agreement with China Unicom Tianjin Branch to build a "5G+ intelligent assembly Joint laboratory", enabling the world's first flexible intelligent assembly system for body door cover. At the same time, focusing on the integration of 5G technology and the existing R & D design system, production control system and service management system in assembly production, comprehensively promoting the profound transformation of production processes such as R & D design, production and manufacturing, and management services in 5G vertical industries, has made substantial progress.

Only the reformers advance, only the innovators are strong, and only the innovators win. 22 years of "TJASSET" to ride the wind and waves, and continue to integrate new ideas, new achievements, new technologies, 2018, 2019 two years of business income of more than 1.5 billion yuan, now, all domestic well-known brands of automobile manufacturing production lines and overseas more than 10 countries have "TJASSET" mark. In the future, TJASSET Company will rely on the intelligent gathering platform of Tianjin Zhigu · Hagong TJASSET Intelligent Industrial Park, which will be completed in 2022, to continue to promote the industrial intelligent strategic layout of "intelligent design + intelligent manufacturing + intelligent testing", so that more industrial equipment can achieve Fuzhen and made in China.
