How does the digital twin smart factory empower the four workshops of heavy trucks through digital technology?

I just visited Beiqi Heavy Duty Truck Digital Gemini Smart Factory last month. Tell me what I saw.

The first is the digital twin factory. If the existing "black factory" and "unmanned factory" are in the form of smart factory 1.0, then the digital twin empowerment factory is basically smart factory 2.0.

The new factory, BAIC Heavy Truck, was planned from the top-level design at the initial stage, taking the lead in establishing the first digital twin intelligent factory, DT@ifactory, and building the China manufacturing demonstration base in 2025, so as to achieve high quality and low cost through digital intelligent innovation.

Stamping workshop: introduce the world's leading high-speed automatic stamping production line, avoid design defects and improve the quality of the whole vehicle through digital simulation analysis of stamping; It is the first automatic blue-light intelligent scanning device with 360 automatic measurement. The measurement accuracy reaches 0.02mm digital measurement of parts, ensuring the quality qualification rate of stamping parts 100%.

Welding workshop: fully automatic welding production line, all robots can weld and pick up parts. German KUKA robot adopts digital simulation technology combined with MES system for real-time interaction, with accurate welding and stable quality. The qualified rate of solder joint positioning is 99.8%, and the qualified rate of full-size body is 95%. Three-coordinate detection runs through the whole process, and 100% monitors the accuracy and quality of the body in white; The industry's first quantitative glue filling process, isv glue coating visual guidance, online detection, make the cab stronger and better sealed.

Painting workshop: The painting workshop is designed by the electrophoretic turnover conveying technology first applied in domestic commercial vehicles, and the green film pretreatment material is applied to effectively improve the anti-corrosion ability of the car body. The body gluing is completed by 8 multi-joint gluing robots, and the high-precision gluing makes the body sealing excellent. The painting operation is completed by 18 six-axis painting robot. Adopt 32B+2 varnish spraying process with the best appearance and performance in the industry, and introduce international first-class paint suppliers. Make the appearance quality of paint reach the advanced level of the industry.

Assembly workshop: it has the largest digital twin assembly workshop in Asia, and realizes the twin mapping between production state and real scene through data transmission process parameters; Visualize real-time production data, even accurate to the torque of the screw; The process and monitoring data are homomorphic, and the assembly qualification rate is 100%.
