Problems solved by technology

However, there are some problems in this method. For example, the protrusions are tightly attached to the target board, which leads to the consumption of a large amount of etching solution to etch the protrusions in the subsequent etching process, thereby increasing the production cost; the sharpness of the processed antenna >20μm, the sharpness of the antenna will cause the antenna to be unable to stably retract the microwave signal, resulting in the antenna being unable to achieve stable transmission of the signal

Abstract

The invention discloses a machining device and method for the sharpness of an antenna target plate. The machining device comprises a target plate transferring mechanism, a conveying mechanism, a sand blasting mechanism and a protective shell. The protective shell comprises a target plate bottom support and a target plate upper cover, the target plate upper cover is buckled on the target plate bottom support, and the protective shell is used for placing a target plate; the target plate transferring mechanism is used for transferring the protective shell to the conveying mechanism; the sand blasting mechanism comprises a sand blasting pool and a plurality of sand nozzles, and the sand nozzles are used for blasting sands to the target plate; and the conveying mechanism comprises two groups of conveying plates which are oppositely arranged, two conveying chains and a second motor, each group of conveying plates comprises an outer plate and an inner plate which are oppositely arranged, one conveying chain is located between the outer plate and the inner plate, and the conveying chains are used for placing the protective shell and enabling the protective shell to move from one end of the sand blasting mechanism to the other end of the sand blasting mechanism. By using the machining device and method disclosed by the invention, uniform sand blasting can be independently conducted on bulges, so that the mechanical strength of each bulge is weakened; and after etching treatment, an antenna with the sharpness smaller than 20 microns can be obtained.

Description

technical field [0001] The invention relates to the technical field of radar antenna processing, in particular to a processing device and method for sharpness of an antenna target plate. Background technique [0002] In order to ensure the stable transmission of signals by the antenna, it is necessary to control the sharpness of the antenna target board within an appropriate range. The method in the prior art is to process a triangular, circular or square shape on the four PAD positions of the target board by means of gain compensation. bump, and then the target board is subjected to copper reduction, copper deposition, exposure, electroplating, and etching. However, there are some problems in this method. For example, the protrusions are tightly attached to the target board, which leads to the consumption of a large amount of etching solution to etch the protrusions in the subsequent etching process, thereby increasing the production cost; the sharpness of the processed ant...
