A rapid assembly method for a radiation unit with a special-shaped cavity

Abstract

The invention discloses a rapid assembling method of special-shaped cavity radiating units. The method is characterized by comprising the following steps that: S1, the assembling feature elements of radiating units are determined; S2, a feature element matching template library is created; S3, the images of assembling features are acquired and pre-processed; S4, the contours of the assembling features are recognized; S5, 3D reconstruction is performed for the assembling features; S6, the radiating units are grouped based on manufacturing precision; S7, the minimum variance of the selecting andmatching scheme of the radiating units is solved; and S8, assembling accuracy is predicted and controlled in real time based on actually measured data. With the rapid assembling method of the special-shaped cavity radiating units provided by the invention adopted, the accuracy and consistency of the assembling of the radiating units can be greatly improved; the batch stability of product qualitycan be ensured; the assembling features rapid measurement and assembling scheme automatic planning of the radiating units can be realized; assembling preparation cycles can be greatly reduced; an assembling process can be optimized automatically; the squeezing of the radiating units during an assembling process can be avoided; and repeated trail assembling and disassembling processes can be reduced.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a rapid assembly method for a radiation unit with a special-shaped cavity. Background technique [0002] Phased array technology has developed rapidly in recent years. Because of its unparalleled performance advantages, it has brought a profound impact on the development of radar systems and is widely used in various radar systems. With the development of military technology in the world, the requirements for the tactics and technical indicators of the phased array radar system are getting higher and higher. [0003] The radiation unit is the basic structural unit and key component of the phased array antenna. It can effectively radiate or receive radio waves. The demand for a single radar is huge (thousands to tens of thousands), and the three-dimensional assembly density and precision requirements are high. The assembly error of the radiating unit to the predetermined i...
