Description

Technical Field

[0001] The utility model relates to the field of electroplating processing, in particular to an electroplating centrifugal drying device. Background Art

[0002] Electroplating is a process that uses the principle of electrolysis to plate a thin layer of other metals or alloys on the surface of certain metals or plastic materials. After the workpiece is electroplated, it can effectively prevent oxidation, improve the wear resistance, conductivity, corrosion resistance of the workpiece, and enhance the beauty of the workpiece.

[0003] In the electroplating process, the product needs to go through cleaning, polishing, water washing, passivation, water washing, centrifugal drying and other processes after electroplating. If a closed process is required, it also needs to go through a closed and centrifugal drying process. The current centrifugal dryer uses a flip cover structure, and hot air enters and exits from the side of the centrifugal chamber. This structure has the following defects:

[0004] 1. The flip-up cover structure requires a large operating space above. This structure has little effect on offline operations, but when used on an automated electroplating line, because the running track of the crane is located above it, the flip-up cover may interfere with the running rhythm of the crane, and the running rhythm of the crane needs to be adjusted, affecting the production rhythm;

[0005] 2. Hot air enters the centrifugal chamber from the side, and the drying effect is not as good as the top air inlet structure, but the flip cover structure affects the top air inlet design;

[0006] 3. The centrifugal chamber is not designed with a drain port, so the thrown liquid cannot be discharged in time, affecting the drying of the product. The equipment also needs frequent maintenance. The liquid contains passivation liquid, sealing agent and other substances. These substances will accumulate in the centrifugal chamber and solidify, affecting the use of the device.

[0007] Based on this, the present application provides a sliding cover type electroplating centrifugal drying device to solve the above problems. Utility Model Content
