Description

Technical Field

[0001] The utility model relates to the technical field of electroplating, in particular to vacuum cleaning electroplating equipment for workpieces with needle-shaped pores. Background Art

[0002] Electroplating is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, thereby changing the surface properties of the substrate and preventing metal oxidation and rust. Electroplating is mainly divided into rack plating, barrel plating, continuous plating and brush plating. Among them, barrel plating is mainly suitable for the electroplating of small parts that cannot or are not suitable for hanging due to factors such as shape and size. A certain number of small parts are placed in a special roller, and various metal or alloy coatings are deposited on the surface of the parts in an indirect conductive manner under the rolling state, so as to achieve surface protection, decoration and various functional purposes.

[0003] In actual applications, after a period of use, the plating of the workpiece will wear out or fall off, so the workpiece needs to be re-electroplated. Since the workpiece is contaminated with a lot of oil or dust during use, it needs to go through a cleaning process before electroplating. However, during the cleaning process, if the workpiece surface has needle-shaped pores, the gas remaining in the needle-shaped pores of the workpiece will cause the cleaning liquid to form a certain tension on the surface of the needle-shaped pores, making it impossible for the cleaning liquid to enter the needle-shaped pores of the workpiece, resulting in the workpiece cannot be completely cleaned, which also indirectly affects the quality of the plating formed on the workpiece in the subsequent electroplating process.
