Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of barrel plating, in particular to a barrel plating device for processing of mobile phone metal accessories and a barrel plating process thereof. BACKGROUND

[0002] Barrel plating is a kind of electroplating method, which is suitable for small-sized and large-quantity parts (such as screws, nuts, washers, electronic components, etc.). It puts the parts to be plated into a specially designed and rotatable barrel (called "barrel"), which slowly rotates in the electroplating solution, so that the parts are evenly deposited with metal coating during the rolling process.

[0003] In the existing barrel plating technology, a hatch is arranged on the barrel, and the hatch is generally opened or closed manually to realize the entry and exit of the parts. However, since the barrel comes out of the electroplating solution, even after water washing and draining, there is still electroplating solution on the surface, so the manual opening or closing of the hatch is easy to cause the electroplating solution to adhere to the skin of the person, which will have adverse effects on the health of the person in the long run.

[0004] In addition, in order to avoid the A-pool electroplating solution from being brought into the B-pool, when the barrel is lifted from the A-pool, it will not be immediately moved into the B-pool, but will be suspended above the A-pool for a period of time (for example, 30-90 seconds) to allow the electroplating solution to fall back into the A-pool. That is, a period of time will be wasted, which will greatly affect the efficiency in mass production, so it is necessary to improve this point to improve the efficiency.
