Description

Technical Field

[0001] The utility model relates to a printing plate etching device, in particular to a quick-detachable etching nozzle spray rod. Background Art

[0002] Etching is a technique that uses chemical reactions or physical impacts to remove materials. Etching technology can be divided into two categories: wet etching and dry etching. Etching is usually referred to as photochemical etching, which refers to the removal of the protective film of the area to be etched after exposure and development. During etching, the area is exposed to chemical solutions to achieve the effect of dissolution and corrosion, forming a concave-convex or hollow-out effect. Usually, the larger the etching droplets sprayed on the substrate by the etcher, the more serious the side etching, and the side etching will seriously affect the accuracy of the printed conductors on the substrate. Therefore, in order to improve the accuracy of the printed conductors on the substrate, it is necessary to reduce the volume of the etching droplets sprayed on the substrate by the etcher during the etching process, which places higher requirements on the accuracy of the etcher. For this reason, a two-fluid etching device has appeared on the market, such as the authorization announcement number CN 212278554 U's utility model patent discloses "a two-fluid etching manifold", the two-fluid etching manifold comprises a manifold body and a plurality of spray devices arranged on the manifold body, wherein the plurality of spray devices are arranged in sequence along the length direction of the manifold body, each spray device comprises a spray body and a nozzle arranged on the spray body, wherein the spray body is installed on the manifold body; the spray body is provided with an air inlet and a liquid inlet, wherein the air inlet and the liquid inlet are arranged in sequence along the length direction of the spray body; the manifold body is provided with a gas inlet and a liquid inlet, wherein the gas inlet is communicated with the air inlet on each spray body through a gas delivery pipeline, and the liquid inlet is communicated with the liquid inlet on each spray body through a liquid delivery pipeline; the nozzle is installed on the spray body through a detachable connection structure, the spray body is provided with a limit groove for limiting the rotation of the nozzle at a position corresponding to the nozzle, and the nozzle is provided with a matching portion that matches the limit groove; when the nozzle is installed on the spray body through the detachable connection structure, the matching portion on the nozzle matches the limit groove on the spray body.
