Description

Technical Field

[0001] The utility model relates to the technical field of electroplating processing, in particular to a surface pretreatment device for electroplating coating processing. Background Art

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto a metal surface using electrolysis. This process involves depositing a thin layer of metal onto the surface of a metal or other material, thereby preventing oxidation (such as rust), improving wear resistance, electrical conductivity, reflectivity, corrosion resistance (such as copper sulfate), and enhancing aesthetics. Many coins also have an electroplated coating.

[0003] Currently, the workpiece surface needs to be cleaned before electroplating to remove oil, dust and other contaminants, and then before electroplating, it must be ensured that the workpiece is completely dry to prevent water droplets from forming stains or bubbles during the electroplating process.

[0004] However, most of the current surface pretreatment devices for electroplating coating processing use an immersion and brushing method to pretreat the workpiece surface. The reaction speed is slow, and the surface needs to be manually brushed. The cleaning liquid also needs to be stirred, which is very troublesome, resulting in low cleaning efficiency and is not conducive to batch electroplating processing of workpieces.
