[0034] The embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0035] See Figure 1 to Figure 2 As shown, the electroplating device includes a sub-tank 1 and a mother tank 8, and a liquid return pipe 3 is arranged in the sub-tank 1. One end of the liquid return pipe 3 is communicated with the mother tank 9 through the return pipe 7, and the mother tank 9 passes the liquid inlet. The pipe 6 and the liquid feed pump 8 installed on it communicate with the sub-tank 1 ; it also includes an ampere-hour metering pump 5 for cobalt supplementation, and the outlet end of the ampere-hour metering pump 5 corresponds to the subtank 1 . During electroplating, the mold copper plate 4 is used as the cathode, and the nickel-buttoned titanium basket 2 is filled as the cathode and placed in the electroplating solution of the sub-tank 1 to conduct electroplating of the cobalt content layer of the mold copper plate. In this embodimen...
