Description

Technical Field

[0001] This invention relates to the field of satellite assembly and storage technology, and in particular to an intelligent satellite assembly and storage system and its operating method. Background Technology

[0002] With the rapid development of microelectronics, communication, and materials technologies, the maturity of the satellite manufacturing industry chain and the speed of technological iteration are improving in tandem. Many manufacturers now possess the capability to independently develop and manufacture various types of satellites. As the satellite application market expands, the demand in the satellite production, manufacturing, and assembly sectors is also increasing. This is mainly reflected in the shortening of satellite development cycles and the increased number of satellites produced in batches, which places higher demands on assembly production capacity, such as the efficiency and accuracy of satellite assembly. These factors have a crucial impact on the satellite development cycle.

[0003] Warehousing is a crucial part of satellite assembly. Traditional warehousing systems consist of multiple racks, each with stacked shelves. Each shelf can hold materials, allowing for the storage of large quantities of different types. However, the sheer variety and lack of a clear storage pattern of materials lead to significant time-consuming sorting processes when retrieving items. Furthermore, even when retrieving materials from the same batch, their locations differ, resulting in wasted time searching and inefficient retrieval. This manually assisted warehousing model is not only resource-intensive but also inefficient, failing to meet the ever-increasing demands of satellite production. Summary of the Invention

[0054] Based on the above structure, the present invention also provides a method for operating an intelligent satellite assembly and storage system, comprising the following steps:

[0055] S1. Computer 2 transmits the required material information to controller 13. Controller 13 feeds back the location information of the required material to computer 2. Computer 2 sends the location information to controller 13. Controller 13 then controls the turntable mechanism 15 through motor 22 to rotate the designated material box 26 to the correct position where the robotic arm 12 can pick up the material. Then controller 13 sends a command to robotic arm 12 and drives robotic arm 12 to take out the material box 26, pass it through the inlet / outlet channel 9, and place it on the picking platform 8.

[0056] S2. After the assembly personnel take out the material from the material box 26 at the location of the platform 8, the computer 2 sends a message to the controller 13 that the material has been taken.

[0057] S3. The computer 2 receives the signal from the controller 13 and drives the robotic arm 12 to grab the material box 26 at the position of the picking platform 8. At the same time, the turntable mechanism 15 drives the material box 26 to rotate from its placement position to the picking position, and the robotic arm 12 puts the material box 26 back on the turntable mechanism 15.

[0058] S4. The assembly personnel can view the installation information of the stand-alone unit through the digital model display module 3 of the computer 2, and then carry out the installation of the satellite products according to the guidance of the computer information;

[0059] S5. After the single-unit installation is completed, the inspection personnel check the installation status of the single unit according to the process specifications, fill in the tracking record card on computer 2, and submit the confirmation information on computer 2 after confirming that there are no errors.

[0061] This invention enables automated material management. When assembly personnel retrieve materials, the computer automatically issues instructions to control the robotic arm and turntable mechanism to return the empty material box to its original position, thus achieving automated material management.

[0062] Through this intelligent, digital, and automated working method, the system can greatly improve the efficiency and accuracy of satellite assembly, reduce manpower consumption, and meet the needs of modern satellite manufacturing.
