The utility model provides an automated electroplating production line which comprises the following steps: during work, putting a clock shell in an ultrasonic cleaning tank by using a first electroplating trolley and a shell clamping device for performing primary cleaning; then, feeding the clock shell into a normal temperature water rinsing tank by virtue of a circulating conveyer belt on a conveying bracket in the ultrasonic cleaning tank for cleaning for the second time; then, feeding the clock shell into a hot water rinsing tank by virtue of a circulating conveyer belt on a conveying bracket in an ultrasonic rinsing tank; and finally, feeding the clock shell onto a second electroplating trolley by virtue of a circulating conveyer belt on a conveying bracket in the hot water rinsing tank, wherein the second electroplating trolley drives the clock shell to enter into the electroplating tank for electroplating treatment. By cleaning the clock shell by ultrasonic waves twice, normal temperature water once and hot water once, impurities such as dirt, ash and clingage on the surface of the clock shell are cleaned to prevent the condition that the subsequent electroplating layer is poor in quality and is bubbled, peeled and floated as impurities exist on the surface of the clock shell, so that the electroplating layer of the clock shell is uniform, difficult to fall and good in wear resistance.
