The invention relates to an electroplating device for electroplating continuously delivered flexible substrates. The electroplating device comprises a sending wheel, a coiling wheel, an electroplating tank containing electroplating solution, a plurality of conductive delivery wheels and a plurality of anode plates, wherein the sending wheel and the coiling wheel are both arranged outside the electroplating tank; the plurality of delivery wheels and the plurality of anode plates are all arranged in the electroplating tank; the plurality of anode plates and the plurality of conductive delivery wheels are all immersed in the electroplating solution; the sending wheel is used for sending the flexible substrates to the electroplating tank; the plurality of delivery wheels are used for delivering the flexible substrates sent by the sending wheel to the coiling wheel by rotation and conducting power to the delivered flexible substrate; the plurality of anode plates are basically arranged in parallel; the flexible substrates are delivered between the neighboring two anode plates when being delivered by the two delivery wheels; and the coiling wheel is used for coiling the electroplated flexible substrates from the plurality of delivery wheels.
