Description

Technical Field

[0001] This utility model relates to the field of electroplating, and in particular to a drying device after electroplating. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It utilizes electrolysis to coat the surface of metal or other material parts with a metallic film, thereby preventing metal oxidation and improving wear resistance, conductivity, reflectivity, corrosion resistance, and aesthetics. During electroplating, the plating metal or other insoluble material acts as the anode, and the workpiece to be plated acts as the cathode. The cations of the plating metal are reduced on the surface of the workpiece to form the plating layer. To eliminate interference from other cations and to ensure a uniform and firm plating layer, a solution containing the cations of the plating metal is used as the electroplating bath to maintain a constant concentration of the plating metal cations.

[0003] However, after electroplating, the plated parts need to be dried to improve electroplating efficiency. Traditional electroplating drying equipment, such as the technical solution protected by the patent application number CN202110760089.1 entitled "A Uniform Drying Device for Electroplated Parts", does not remove the electroplating solution from the plated parts before drying and has low drying efficiency for small-volume workpieces.

[0029] During operation, the electroplating drying device 10 adds electroplated workpieces to be dried into the upper rotating drum 160 via the feeding valve 161. In the upper rotating mechanism 100, the drive motor 130 drives the rotating drum 160 to rotate via the drive disc 140 and two drive columns 150.

After the third preset time, once the electroplated workpieces in the lower rotating drum 160 are dried, the feeding valve 161 is opened, and the dried electroplated workpieces are discharged into an external storage box. The aforementioned post-plating drying device 10 removes the plating solution from the plated parts before drying and has high drying efficiency for small-volume workpieces. It should be noted that the duration of the first, second, and third preset times is related to the number of electroplated workpieces to be dried; those skilled in the art can set an approximate range based on experience. The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
