Abstract

The invention discloses a precise alignment assembly device and method for a combined array element. Through careful analysis of the structural size of the combined array element, a special welding alignment tooling fixture for the combined array element is designed, and a positioning column is used to align the inner The position of the conductor is precisely positioned, and the butt slot of the inner conductor is designed according to the size of the alignment hole of the filter, and welding is performed after the butt joint to ensure that the position accuracy of the inner conductor meets the requirements; and the welding process is improved, and the inner conductor is added to the inner conductor cylinder before welding. The outer circular surface is tinned. When soldering, first solder at the position a of the inner conductor of the printed board, and then solder at the position b around the lower end of the inner conductor to ensure a good soldering between the inner conductor and the pad of the printed board. The shape of the spot ensures the strength of the solder joint; after the inner conductor is welded, it can be aligned with the filter accurately, preventing the inner conductor from being stressed after the assembly of the combined array element, and obtaining good assembly quality.

Description

technical field

[0001] The invention belongs to the field of precise installation of antennas, and in particular relates to a device and method for precise alignment and assembly of combined array elements. Background technique

[0002] The combined array element is an important part of an array antenna. The inner conductors of the combined array elements need to be welded on the array elements, and must be aligned with the filter components before being plugged in. Therefore, it is necessary to ensure that the inner conductor has a high position accuracy, so as to avoid the force on the solder joint of the inner conductor after the subsequent array element is connected with the filter component, which will affect the product quality.

[0003] At present, the welding of combined array elements faces the following problems:

[0004] Because the multiple inner conductors on the combined array element are on the same plane, they all need to be connected to the filter after th...
