Description

Technical Field

[0001] The present invention belongs to the field of antenna reflector product assembly, and in particular relates to a multifunctional transportation, transfer and parking device suitable for antenna reflectors. Background Art

[0002] During the early stages of final assembly of antenna reflector products, the antenna reflector needs to be transported over long distances to the factory workstation. Due to the high requirements on the surface accuracy of the antenna reflector and the great influence of assembly stress, the coated surface is fragile and easily contaminated and damaged. Currently, foam boxes are commonly used for transportation and parking. However, there is a risk of contamination by excess objects and scratching of the foam by the reflector. Moreover, the reflector can only be taken out of the box by manual lifting, which involves uncontrollable factors. In addition to foam boxes, rigid transfer and parking tooling is also commonly used. However, rigid transfer and parking tooling has assembly stress that affects the surface accuracy of the reflector, and it only solves the problem of fixed parking of the reflector. It has a single function and low efficiency, and cannot meet the flexible flow requirements of the entire process of final assembly of the antenna reflector.

[0003] In the related prior art, a three-axis polarity test transport and parking device for satellites (patent document CN114572428A) provides a three-axis polarity test transport and parking device for satellites, which is used for attitude flipping during polarity testing of micro-satellites. Its satellite mounting plate is rigidly connected to the micro-satellite, and the micro-satellite is driven to undergo attitude change by shaking the handwheel. However, when the satellite flips to a certain angle, the following technical problems exist: there is stress at the connection between the satellite mounting plate and the micro-satellite, and a flexible stress-free connection and retention function cannot be achieved, and it cannot be used for long-distance stress-free transportation and parking of high-precision antenna reflectors.

[0004] In summary, the transportation of antenna reflectors presents high risks, high vibration, assembly stress on the reflector caused by tooling, difficulty in transporting between workstations in the factory, and the coating is easily contaminated and difficult to protect. A transport and parking device for the antenna reflector must simultaneously meet requirements such as stress-free parking, reliable long-distance, shock-absorbing transportation, coating surface protection, and flexible transport between workstations in the factory.
