Portable etching inspection device {PORTABLE ELECTROLYSIS ETCHING APPARATUS}

The present invention relates to a portable etching inspection device, and more particularly, a portable etching device capable of simultaneously performing photographing and hardness inspection by mounting a mounting jig and exchanging a nozzle suitable for an area to be inspected for metal. It's about inspection equipment.

In general, when it is difficult to observe and analyze the metal surface by moving a product or material from the site to a laboratory or taking a specimen, the metal surface is electrochemically eroded (electrolytic etching) on the site using portable equipment and then corroded. The surface is photographed and the hardness is measured.

Since electrolytic etching is processed using a chemical reaction, non-uniform processing occurs if foreign substances are attached to the surface of the workpiece, so a cleaning process to remove foreign substances before and during processing is required.

In order to electrolytically etch a metal surface in the field, a worker must install suitable equipment for each part of the metal surface each time and replace it after the work is completed. In particular, since the nozzle, which is a corrosion equipment, is used in a limited area of the metal surface, it is moved up, down, left and right to etch a large area. At this time, friction between foreign substances on the metal surface causes damage to the metal surface, and thus accurate results are obtained. There is a problem that occurs when you can't get it.

On the other hand, Korean Patent Registration No. 10-1164596 discloses an electrolytic etching bath for performing an etching process on a metal layer formed on an insulating substrate, filling the electrolytic etching bath, an electrolyte solution having an etching power, and an electrolytic etching bath disposed in the etching process. A nozzle for spraying the used etchant, a first electrode for electrolytic etching disposed between the metal layer and the nozzle, a first rectifier for applying current by connecting the first electrode for electrolytic etching and the metal layer, and the metal of the metal layer etched by the etchant Disclosed is an electrolytic etching device capable of forming an ultra-fine pattern by providing an etching force close to vertical to a metal layer to be etched using an electric electrode, including a reducing device for reducing ions.
