The invention discloses an electroplating device which comprises a rack, a number of anode boxes, a first electric cylinder, a second electric cylinder, a support plate, a support frame, an exhaust device, an electroplating liquid and a hanging basket. The upper end of the rack is provided with an electroplating cell chamber, the electroplating cell chamber is internally provided with the electroplating liquid, and the electroplating cell chamber is also internally provided with a number of anode boxes; the anode boxes are provided with side walls of the electroplating cell chamber; the upperend of the rack is provided with the support frame; the upper end of the support frame is provided with the support plate; one end of the support plate extends out of the rack, and the lower end of the support plate is fixedly connected with the first electric cylinder. The upper end of the rack is provided with the electroplating cell chamber and the electroplating liquid contained in the electroplating cell chamber is used for electroplating a workpiece, precipitation of the electroplating liquid is prevented by arrangement of a stirring device at the bottom of the electroplating cell chamber, and the electroplating effect is prevented from being affected; through arrangement of the exhaust device on the upper end of the rack, exhaust gas produced in the electroplating process is absorbed and discharged by an exhaust pipeline, and damage on an operator is reduced.
