The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

The anode box provided by the embodiment is arranged in a plating tank of the plating device, and discharges electricity to change copper in the plating solution into copper ions in the plating process.

As shown in fig. 1, an embodiment of the anode box provided in this embodiment includes: the anode plate 4 is provided with a plurality of small electrode plates 1 which are arranged in sequence along the transverse direction, and when the anode plate 4 is used, each small electrode plate 1 is respectively communicated with a power supply. And at least part of the two adjacent small polar plates 1 are arranged in a staggered way along the moving direction of the product to be plated, so that the potential difference generated in the transverse direction when the whole anode plate 4 is adopted is reduced, and the electroplating effect is more uniform and better.

As shown in fig. 1, in the anode box provided by this embodiment, the staggered edge between two adjacent small plates 1 is a bevel edge. Through the arrangement of the bevel edge, the problem that an electroplating blind area appears between two adjacent small polar plates 1 when products to be electroplated are electroplated can be avoided. In addition, as an alternative embodiment, the staggered edge between two adjacent small electrode plates 1 may also be an arc-shaped edge, such as an S-shaped edge.

As shown in fig. 1, in the anode box provided by this embodiment, an insulating plate 2 is disposed between two adjacent small electrode plates 1. The insulation between two adjacent small polar plates 1 can be improved through the insulating plate 2, and the electroplating effect is ensured. In addition, as an alternative embodiment, the insulating plate 2 may be omitted, and the insulating property may be improved by spacing a certain distance between two adjacent small electrode plates 1.

As shown in fig. 1, in the anode box provided in this embodiment, the insulating plate 2 is a vertical partition plate, so that the anode box can be more conveniently installed.

As shown in fig. 1, in the anode box provided by this embodiment, the anode plate 4 has a plurality of plate groups 3 arranged in sequence along the moving direction of the product to be coated, and each of the plate groups 3 has a plurality of small plates 1 arranged in sequence along the transverse direction. Through the arrangement of the plurality of the electrode plate groups 3, the length of the anode box in the moving direction of the product to be coated can be increased, so that the size of one anode box is increased, and the number of the anode boxes arranged in the electroplating device is reduced.

As shown in fig. 1, in the anode box provided by this embodiment, the front edge of the electrode plate group 3 facing the incoming direction of the product to be coated and the back edge facing the moving direction of the product to be coated are arranged in parallel. By such arrangement, the anode plate 4 can be integrally designed into a rectangular structure, thereby facilitating installation.

As shown in fig. 1, in the anode box provided by this embodiment, the lengths of the small plates 1 in the moving direction of the product to be coated are equal. Through the arrangement, after the small polar plates 1 are combined to form a whole anode plate 4, the anode plate 4 can form a rectangular structure, so that the assembly of the anode box is convenient. In this embodiment, the small electrode plates 1 have the same area. In this way, the currents flowing through the respective small electrode plates 1 can be equalized, and the plating effect can be further improved.

As shown in fig. 1, in the anode box provided by this embodiment, a frame is disposed on the periphery of an anode plate 4 composed of a plurality of small electrode plates 1, a horizontal bar and a vertical bar are disposed inside the frame, and the horizontal bar and the vertical bar can be used to strengthen the support of each small electrode plate 1, thereby ensuring the overall stability of the anode plate 4.

As shown in fig. 1, in the anode box provided in this embodiment, a plurality of connecting rods extending upward are sequentially disposed at the side of the frame, and the connecting rods can be used for fixing and installing the anode box.

As shown in fig. 2, the present embodiment further provides an electroplating apparatus, including: and a plurality of groups of the anode boxes are arranged in the electroplating bath along the moving direction of the product to be plated. When the electroplating tank works, a product to be plated sequentially passes through the bottom of the anode box in the electroplating tank, so that electroplating is performed.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
