As shown in fig. 1 and fig. 3, the battery plate electroplating apparatus includes at least two electroplating baths 10, at least two sets of power supply modules, a cleaning tank 20 and an electroplating carrier 30, wherein an anode plate 101 is disposed in each electroplating bath 10, the anode plate 101 is a metal to be plated for electroplating a battery plate 301, the anode plate 101 in each electroplating bath 10 is made of a different material, during the electroplating process, the anode plate 101 is parallel to and opposite to the battery plate 301 to be plated, and after the battery plate 301 is sequentially electroplated by the anode plates 101 in the plurality of electroplating baths 10, the surface of the battery plate is plated with a complete plating layer. The anode plate 101 may be one or a combination of a planar structure, a mesh structure, a linear structure, and a dot structure, and the specific structural form of the anode plate 101 is not limited in this embodiment.

The first conductive rail 401 may be an L-shaped steel, i-shaped steel, or a channel-shaped steel, and the specific structural form of the first conductive rail 401 is not limited in this embodiment. At least two sections of first conductive rails 401 are arranged at intervals in a direction parallel to the anode plate 101, every two adjacent sections of first conductive rails 401 are connected in an insulated mode to form a continuous first transmission rail 40, the first transmission rail 40 is distributed on one side of the electroplating tank 10 or in a frame of a tank body of the electroplating tank 10, the form of the first transmission rail 40 can be freely set according to the space size of a production workshop, and when the space of the production workshop is large enough, the adjacent first conductive rails 401 can be arranged in a straight line to form the linear first transmission rail 40; when the space of the production plant is small, the adjacent first conductive tracks 401 may be arranged along a curve to form the serpentine-shaped first transfer track 40. Two adjacent first conductive rails 401 are connected end to end in an insulated manner, and the connection parts can be isolated by using an insulating piece 402 made of insulating materials such as resin, ceramic or quartz.

If the current value set by the power supply is changed, the current magnitude of the corresponding battery piece 301 is changed, and the plating speed is changed accordingly. In the same electroplating time, if the current value set by the power supply is larger, the larger the negative electrode current on the cell 301 is, the faster the metal cations in the electroplating solution are attached to the cell 301, and the faster the corresponding electroplating speed is; if the current value set by the power supply is small, the smaller the current of the negative electrode on the cell piece 301 is, the slower the speed of the metal cations in the plating solution adhering to the cell piece 301 is, and the smaller the corresponding plating speed is. In addition, the sliding speed of the electroplating carrier 30 on the first transportation rail 40 can be set according to the requirement, and the electroplating time is influenced by the length of the first transportation rail 40, when the length of the first transportation rail 40 is longer, the electroplating time is correspondingly prolonged, and when the length of the first transportation rail 40 is shorter, the electroplating time is correspondingly shortened.

In one embodiment, the first conveying rail 40 is not disposed on the side of the cleaning tank 20, and the electroplating carrier 30 is directly immersed into the cleaning tank 20 for cleaning by using a clamping tool.

It should be noted that, in the process of lifting the electroplating carrier 30 by the hanger 80, the current on the electroplating carrier 30 can be controlled to gradually decrease, and in the process of lowering the electroplating carrier 30 by the hanger 80, the current on the electroplating carrier 30 can be controlled to gradually increase, so that the power consumption of the electroplating operation can be further saved by controlling the current.

Optionally, the hanger 80 is an insulating hanger 80, and wires are distributed in the insulating hanger 80 and used for transmitting current to the first conductive rail 401 and the second conductive rail respectively.

Specifically, the hanger 80 may be an insulating hanger 80 made of an insulating material, in order to achieve electrical connection between the battery piece 301 and the two sections of conductive rails, a wire may be laid in the insulating hanger 80, the wire may be two wires insulated from each other, one wire is used to connect the first conductive rail 401 with the front side of the battery piece 301, and the other wire is used to connect the second conductive rail with the back side of the battery piece 301, so as to avoid short circuit caused by circuit series connection. Therefore, the hanger 80 of the present embodiment can be used as a carrier for hanging the electroplating carrier 30, and can also transmit current to the conductive rails and the battery plates 301 by using the internal wires.

The embodiment of the utility model provides an electroplating device is still provided, electroplating device includes the electroplating device of any preceding embodiment.

Specifically, the electroplating device of this embodiment may use any one of the electroplating devices described above in cooperation with an air knife device, a conveyor, etc., after the battery piece 301 is plated with a metal coating by the electroplating device, the air knife device may blow dry the residual electroplating solution and the cleaning solution on the surface of the battery piece 301, so that the surface of the battery piece 301 is kept dry, and meanwhile, the battery piece 301 after being electroplated is conveyed to a storage location for storage by the conveyor.
