Referring to Fig. 12, there is shown a schematic view of an electroplating bath of the present invention applied to an automated electroplating apparatus 90 having a plurality of electroplating baths 80 arranged in a two-row electroplating arrangement A, B having thermal desorption, water washing, electrolysis The steps of pickling, etc., between the two rows A and B are a walkway C for the operator to walk when necessary. Each column electroplating arrangement A, B is equipped with a hanging device (not shown) and a transmission device (not shown), the hanging device suspends each plating barrel to a different plating tank; and the transmission device and the plating barrel The gears are meshed to rotate the plating barrel. After completing each plating process in column A, the plating tank is translated to column B by the trolley at position D to continue the subsequent plating flow path. After the plated parts are plated, the material is cut at the position E, and then paralleled to the front end of the column A. After the plated parts are placed in the plating barrel, another plating operation is performed.

Conventional electroplating barrels are provided with gears only at one end, so when the electroplating barrel is in column A, the gear train is located on the outer side a1 of column A, so the transmission of column A is built. It is arranged on the outer side of column A. When the conventional plating tank is translated to column B, its gear is located on the inner side b1 of column B, close to the walkway C; the transmission device of column B is constructed on the inner side of column B. The missing feature of the conventional structure is that the first transmission is constructed on the outside of one column of plating arrangements (for example, the outer side a1 of column A), and the second transmission is constructed in another column of plating. The inside of the configuration (for example, the inner side b1 of column B), because the walkway C is narrow, is not conducive to maintenance personnel to repair the second transmission. When the electroplating barrel is driven by only one gear, the gear wears faster.

The present invention is provided with a transmission assembly (an external gear, an internal gear and a toothed disc) at both ends of the plating barrel. Therefore, when the plating barrel 10 is located in the A column, the transmission assembly (the external gear 55a) located outside the A1 of the column A can be utilized. To rotate the plating barrel, when the plating barrel 10 is in the B column, the plating barrel can be rotated by the transmission assembly (the external gear 55b) located on the outer side b2 of the column B. Therefore, by using the electroplating barrel of the present invention, two transmission devices can be disposed on the outer sides a1 and b2 of the two columns A and B to facilitate maintenance of the transmission device without having to be in the walkway C. Moreover, when the different gears 55a and 55b rotate the plating barrel, the wear rate of the bottom gear can be reduced, the wear state of the gear can be halved, and the service life can be prolonged.

The electroplating barrel provided by the invention can be assembled into three different electrode structures, which can be adjusted according to different plating conditions. In particular, only one type of electroplating barrel can be converted into different electrode forms, and the manufacturer does not need to prepare various forms of electroplating barrels, which can greatly reduce the cost of production equipment, and can reduce the storage space and electroplating plant required for electroplating barrels. Furthermore, the present invention is provided with a transmission assembly (an external gear, an internal gear and a toothed disc) at both ends of the plating barrel, which is advantageous for repairing the transmission device and reducing the wear rate of the member.

The above examples are merely illustrative of the invention and not limitation. The electroplating barrel provided by the invention is the first structure of the same kind of articles, and has the progressive effect, and is applied according to law.
