Description

Technical Field

[0001] The present invention relates to the field of satellite technology, and in particular to a flipping and parking integrated device suitable for small satellites. Background Art

[0002] With the continuous improvement of basic technological capabilities, the diversified development of the application market, and the strong support of national policies, the industrialization and commercialization of small satellites are becoming increasingly evident, and they are widely used in communications, space science, Earth observation, and technology demonstration. Multi-satellite coordination and network formation are the most prominent features of small satellites. The demand for satellite constellation construction has led to a significant increase in the development of small satellites.

[0003] Small satellites are significantly smaller in mass and volume than large and medium-sized satellites, resulting in shorter development cycles and lower costs. During the final assembly and integration process, large and medium-sized satellites are parked and transported using transfer and parking vehicles, with attitude flips achieved using a two-axis turntable. This requires the constant switching of tooling to meet the satellite's varying state requirements at different stages. This is a time-consuming and labor-intensive process, with numerous operational risks, and cannot meet the low-cost, rapid development needs of small satellites. Therefore, it is necessary to develop an integrated flip and parking device suitable for small satellites that can meet the requirements for parking, test transport, and attitude flips during active component deployment testing or polarity testing during the final assembly and integration process.

[0004] Patent document CN215469230U discloses an automatic flipping platform for satellite installation and debugging, comprising a base frame, a vertical plate fixedly connected to one side of the top of the base frame, a slider having a gap in the inner wall of the vertical plate, a first threaded rod threadedly connected to the inner wall of the slider, and the top of the first threaded rod rotatably connected to the inner wall of the vertical plate via a bearing. This utility model relates to the field of flipping platform technology. This automatic flipping platform for satellite installation and debugging has a stable structure, is easy to operate, and has a high degree of automation, reducing labor costs. Its specific beneficial effects are as follows: through the cooperation of a servo motor, a second threaded rod, and a clamping rod, the position of the second robotic arm can be freely adjusted, facilitating operation by staff and improving work efficiency. The clamping rod also serves to limit the second robotic arm, ensuring that the second robotic arm does not deviate during operation, thereby improving the working quality of the equipment. However, this device cannot achieve adjustment of small satellites along three linear directions. Summary of the Invention
