Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hardware workpiece electroplating processing, in particular to a hardware workpiece electroplating tank processing system. BACKGROUND

[0002] As one of the important processes of metal surface treatment, electroplating is widely used in corrosion protection, wear resistance improvement and appearance decoration treatment of hardware workpieces. The basic principle is that the metal workpiece to be treated is used as the cathode in the electroplating tank, and the electroplating tank contains an electrolyte containing specific metal ions. Under the condition of applying an external electric field, the metal ions on the workpiece surface undergo a reduction reaction, thereby forming a uniform and dense metal plating layer. In practical applications, hardware workpieces are diverse, including screws, fasteners, handles, structural parts, etc., with complex structure, variable size and dense quantity. In order to improve the electroplating efficiency and surface quality, batch or continuous electroplating tanks are usually used to process hardware workpieces.

[0003] According to the search, the utility model patent with publication number CN114574934A discloses a hardware workpiece electroplating processing system. After the workpiece enters the electroplating tank, the workpiece is first driven to rotate forward and then reverse in the electroplating tank through the cooperation of the parts, thereby improving the contact efficiency of the workpiece and the electroplating liquid, increasing the electroplating processing effect, and not needing to add an additional motor to provide power.

[0004] In the above-mentioned scheme, the electroplated workpieces are placed in the discharge frame, and are placed non-fixedly.

If a fixed clamping method is used, the surface of the workpiece is blocked in the local area, the electroplating liquid cannot uniformly contact, the plating layer thickness is uneven, plating is missed or the density is insufficient. Therefore, the present application provides a hardware workpiece electroplating tank processing system. SUMMARY
