Description

Automatic electro-polishing apparatus The present invention relates to an electrolytic polishing device, and more specifically, to an electrolytic polishing device for performing electrolytic polishing on a welded area. Polishing is generally a process of smoothing the surface of a metal and can be classified into mechanical polishing and electrochemical polishing. Among these, electrochemical polishing, primarily known as electrolytic polishing, refers to a polishing method performed through the selective dissolution of the metal surface using a solution and electrical action. Electropolishing of this type has the advantage of flattening the surface and enhancing gloss by selectively dissolving micro-protrusions on the metal surface, and increasing corrosion resistance by forming a passivation film, which is a thin oxide film. Accordingly, electropolishing has recently become essential in various fields, including the semiconductor sector, and is particularly being performed for the post-treatment of welded parts of various workpieces. However, conventional electrolytic polishing devices and electrolytic polishing systems have low efficiency because the user must manually immerse the object to be polished in the electrolyte and apply power to perform polishing on the surface, and there is a problem in that they cannot perform partial polishing on a small area such as a welded part. Accordingly, conventional electrolytic polishing devices and systems have a problem in that the solution provided for performing electrolytic polishing on limited welded areas is excessively wasted. In addition, conventional electrolytic polishing devices and systems have a problem of low versatility because, even when performing selective automatic electrolytic polishing on welded areas, they cannot perform precise polishing in response to various welded areas of the object to be polished. In addition, conventional electrolytic polishing devices and systems have the problem of low process efficiency because the processes before and after electrolytic polishing are handled manually or sequentially.
