There is the first small satellite intelligent production line in China characterized by “flexible intelligence, digital twins, and cloud manufacturing”.
With the rapid development of Satellite constellation such as communication and remote sensing, satellite research and production has moved from traditional single and small batch to large-scale batch. Through 6 production information systems, including process management systems, manufacturing execution management systems, and intelligent logistics management systems, automatic distribution, intelligent assembly, and efficient testing of production lines have been realized. In 2 years, this production line has completed 10+ satellites and several 10+ single-system tasks in total.
The first glance in the park is the satellite parts warehouse. The system can automatically number, type identification codes, and match warehouse locations based on the size and weight of materials. After the production line issues production instructions, the parts warehouse transports the necessary materials for production to the intelligent assembly system via an automatic guided vehicle.
Part assembly production mainly adopts a human-machine cooperation mode. The manipulator works according to the standardized operation process set by the precise process parameters, which can improve efficiency and eliminate personal error by manual operation. The automation rate of the production line has reached over 50% jobs, it increase the production efficiency of small satellites by over 40%, shorten the single satellite cycle by over 80%, and realized the magnificent transformation from “manufacturing” to “intelligent manufacturing”.
After installing the satellite, it undergoes a series of testing tests, such as comprehensive testing, load testing, accuracy testing, quality characteristic testing, and mechanical and thermal-related tests. After the product is produced and qualified, it is taken offline and stored, waiting for subsequent tasks.
In order to ensure the reliability of the entire process of satellite production quality, the whole factory has reached ISO8. The annual mass production can reach 240 satellites.
