Cathode plate and manufacturing method for manufacturing nickel buckle or cobalt buckle

Abstract

The invention aims at overcoming defects existing in an existing cathode plate, and provides a cathode plate and manufacturing method for a nickel buckle or cobalt buckle. The cathode plate is long inservice life and high in operability. A metal boss is directly machined on the metal substrate (cathode plate), the metal boss serves as the production face of the nickel buckle or cobalt buckle, andthe metal boss and a metal matrix are integrated. In the production process, the common problem that electric conduction is caused by poor contact in the original technology cannot happen, and production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a cathode plate for a nickel button or a cobalt button and a manufacturing method thereof. Background technique [0002] At present, nickel buckle, as a new type of electroplating nickel anode material, is favored by the majority of electroplating nickel users; cobalt, as a congener element of nickel, has very similar physical and chemical properties, and nickel-cobalt or cobalt-nickel alloys often appear in the electroplating and electroforming industries Coating, in the process of electroplating nickel-cobalt or cobalt-nickel alloy, cobalt is added in the form of cobalt sulfate or cobalt sulfamate, which is very expensive. If the cobalt button is added as an anode, the production cost can be greatly reduced, so the cobalt button will inevitably be used in the future There is a large market demand. However, the localization of nickel buttons or cobalt buttons is basically not possible in China. The reason is that the current ...

AI Technical Summary

Problems solved by technology

There are two shortcomings: one is that the metal cylinder and the metal substrate are connected by screws, which is prone to loosening during production, resulting in poor electrical conductivity and a low pass rate of nickel buckles; the other is that due to the difference in thermal conductivity, the gap between the metal cylinder and the insulating material Gaps are prone to appear between the gaps, and nickel buckles will be produced in the cracks, which will cause great difficulties for the later buckle removal. The insulation layer will be greatly damaged when the buckle is taken out, resulting in a reduction in the number of times the cathode plate can be used.
