AI Technical Summary
During the production of surface mount resistors, nickel slag and suspended impurities in the nickel plating solution tend to adhere to and deposit on the inner wall of the nickel plating tank and the outer wall of the barrel plating cylinder, causing blockage of the flow holes and affecting the uniformity of the plating layer and product quality.
An electroplating device was designed, including a cleaning mechanism and a unclogging component. The cleaning mechanism cleans the inner wall of the nickel plating tank and the outer wall of the outer nickel rolling cylinder with a concave brush and soft bristles. The unclogging component automatically unclogs the flow holes with a unclogging column and an arc-shaped extrusion plate, and removes impurities by combining a fixing ring and cleaning soft bristles to prevent impurities from entering the inner nickel rolling cylinder.
It enables simultaneous cleaning of the nickel plating tank and the outer nickel roller, as well as automatic unblocking of the flow holes, improving the flow efficiency of the nickel plating solution, ensuring the uniformity of the plating layer and product quality, and enhancing the protection performance and yield of chip resistors.
