Description

Ultrasonic cleaning device for removing plating solution {ULTRASONIC WAVES WASHER FOR REMOVING PLATING SOLUTION}

The present invention relates to an ultrasonic cleaning device for removing a plating solution, and more particularly, to an ultrasonic cleaning device for removing a plating solution from a portion in which a plating solution may remain, such as a gap or a portion having a different thickness at a junction in a product that has been plated. .

In general, plating is to apply a thin layer of another metal or alloy on a metal surface, and various plating methods are used as needed.

After plating, a process of removing the plating solution is performed. In the case of a flat object to be plated, it can be completely removed by the plating solution, but the object to be plated is not simple in shape, such as a bent portion or a difference in thickness. In this case, the plating solution is not completely removed and remains in the bent portion or gap.

The plating solution that is not removed in this way may cause rust on the object to be plated, which may cause poor appearance, and may cause a situation requiring additional management, such as contamination of the drying device due to the spilled plating solution.

Therefore, depending on the shape of the liquid to be plated, additional processes such as drying and visual inspection are required for the complete removal of the plating liquid.
