Wet etching equipment of antenna baseband for interphone

Abstract

The invention relates to the technical field of interphones as digital products, and discloses wet etching equipment of an antenna baseband for an interphone. The wet etching equipment comprises a shell, wherein a rotating shaft is movably connected to the interior of the shell, a movable plate is movably connected to the surface of the rotating shaft, a sliding rail is formed in the movable plate, a compression spring is connected to the surface of the sliding rail in a sliding mode, a hollow rod is movably connected to the lower end of the compression spring, a feed pipe is movably connectedto the right end of the hollow rod, a spoiler is movably connected to one end, which is far from the hollow rod, of the feed pipe, an adjusting tank is movably connected to one end, which is far fromthe feed pipe, of the hollow rod, spring rods are movably connected to the interior of the adjusting tank and are located on both sides of a guide rod respectively, and a clamping plate is movably connected to one end, which is far from the guide rod, of an airflow pipe. An internal flowing space is narrowed, and therefore, chemical agents in a liquid storage bag can stop flowing out by utilizingsuction airflow when the flow direction of the chemical agents on the surface of a paster is changed, so that the effect of controlling the flow direction of corrosive liquid is achieved.

Description

technical field [0001] The invention relates to the technical field of walkie-talkies for digital products, in particular to an antenna baseband wet-etching manufacturing equipment for walkie-talkies. Background technique [0002] The walkie-talkie is a two-way mobile communication tool. It can talk without any network support, and there is no call fee. It is suitable for relatively fixed and frequent calls, such as construction sites. The existing walkie-talkies are divided into analog walkie-talkies, digital Walkie-talkies and IP walkie-talkies; among them, digital walkie-talkies are the most used, and the core component of the walkie-talkie is the antenna. The quality of the antenna determines the clarity of the walkie-talkie. [0003] The antenna used in the existing walkie-talkie is a microstrip antenna. The microstrip antenna is on a thin dielectric substrate, with a thin metal layer attached on one side as a grounding plate, and a metal patch of a certain shape is mad...

AI Technical Summary

Problems solved by technology

[0003] The antenna used in the existing walkie-talkies is a microstrip antenna. The microstrip antenna is on a thin dielectric substrate, with a thin metal layer attached on one side as a ground plate, and a metal patch of a certain shape is made on the other side by photolithography. The antenna composed of a microstrip line or a coaxial probe feeding the patch; wet etching is often used for the production of metal patches, and traditional wet etching equipment cannot accurately control the amount of chemical etching solution and its flow direction, the corrosive liquid cannot cover the surface of the patch to be etched, which affects the etching effect. Therefore, a wet etching production equipment for antenna basebands for walkie-talkies came into being.
