Barrel plating process production line

The utility model discloses a barrel plating process production line which comprises a plurality of electroplating areas, each electroplating area comprises a plurality of electroplating tanks and the electroplating areas are arranged in a straight line, rollers are placed in the electroplating tanks, and liquids for barrel plating procedures are sequentially contained in the electroplating tanks of different electroplating areas. The number of the plating tanks in different plating areas is matched with the time required by the plating process of the plating areas, the plurality of plating areas are arranged into a plurality of plating tank arrangement lines, the plating areas are distributed on the plating tank arrangement lines, and an exchange travelling crane moving along the plating tank arrangement lines is arranged above the plating tank arrangement lines through a guide rail. According to the utility model, the number of the plating tanks arranged in the electroplating area is positively correlated w
