[0038] In one embodiment, if Figure 1 As shown, a schematic diagram of the structure of an electroplating rack is provided, including: a rack body 01 and a fixing member 02; wherein:
[0039] The fixing part 02 is arranged on the rack body 01, and is used to fix the plate 03 to be electroplated inside the rack body 01; the inner side of the rack body 01 exposes a drainage surface, which is used to improve the uniformity of electroplating when electroplating the plate 03.
[0040] In actual applications, the bracket body 01 can be made of stainless steel so that the bracket can drain through the drainage surface exposed on its inner side; optionally, in actual applications, the inner side of the bracket body 01 is not fitted with rubber packaging to expose the drainage surface. In actual applications, it is not limited to this and depends on the specific application environment. It is all within the protection scope of this application.
[0041] The working process of the above-mentioned electroplating rack is as follows: when electroplating is being carried out, the plate 03 to be electroplated is fixed inside the rack body 01, and the plating liquid in the plating tank electroplates the plate 03. At this time, the drainage surface exposed on the inner side of the rack body 01 distributes the plating current during the electroplating process through the drainage surface, avoiding the current concentration on the edge of the plate 03, resulting in uneven coating thickness on the plate 03, thereby achieving uniform copper plating.
[0042] The electroplating rack of this embodiment includes: a rack body 01 and a fixing part 02, wherein the fixing part 02 is arranged on the rack body 01, so that the plate 03 to be electroplated can be fixed inside the rack body 01 through the fixing part 02, and the inner side of the rack body 01 is provided with an exposed drainage surface, so that when the plate 03 is electroplated, the current in the electroplating process can be distributed through the drainage surface, thereby reducing the electroplating thickness at the edge of the plate and improving the electroplating uniformity of the plate 03.

At this time, the first drainage surface 11 on the rack body 01 distributes the electroplating current during the electroplating process to achieve uniform copper plating; and by bonding the rubber coating on the first rubber coating surface 21, the second rubber coating surface 22 and the third rubber coating surface 23, the loss of the rack body 01 is reduced.
[0047] The electroplating rack of this embodiment adopts the first drainage surface 11 to distribute the electroplating current during the electroplating process, so as to avoid the current being concentrated on the edge of the plate 03, resulting in uneven coating thickness on the plate 03, thereby achieving uniform copper plating; and the first rubber-coated surface 21, the second rubber-coated surface 22 and the third rubber-coated surface 23 on the rack body 01 are bonded with rubber to reduce the corrosion of the electroplating solution to the rack body 01, thereby reducing the loss of the rack body 01.
