Electroplating apparatus

Abstract

An apparatus for electroplating which is applicable to the electroplating of workpiece is disclosed. The apparatus includes: an electroplating solution container, a target, an absorbent piece, and a power supply. All the electroplating solution, workpiece, absorbent piece, and target are placed inside the electroplating solution container with at least partial portions of each workpiece, absorbentpiece and target submerged in the electroplating solution. The positive electrode of the power supply is electrically connected to the target while its negative electrode is electrically connected tothe workpiece and absorbent piece simultaneously. When the power supply imposes a current through the circuit, the target releases metal ions into the electroplating solution and metal ions reduce and a metal coating is formed on the workpiece. In the meantime, carbocations in the electroplating solution are adsorbed on the absorbent piece.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to an electroplating device which uses an adsorbent to adsorb carbon elements in an electroplating solution. Background technique [0002] Since the development of consumer electronic devices, in addition to the functional requirements, the appearance has also become one of the factors considered by consumers when purchasing consumer electronic devices. Most of the consumer electronic products seen at present are made of metal materials such as aluminum alloy or aluminum-magnesium alloy. In order to obtain decorative effects, the outer casings of electronic devices such as mobile phones, computers, and digital cameras are usually surface-treated. Among them, the appearance of the product processed by the electroplating process has a good metal texture and good wear resistance. [0003] Electroplating is one of the common surface treatment methods in modern times. The product...

Problems solved by technology

However, these additives contain carbon elements. During the electroplating process, the carbon elements are deposited on the electroplating workpiece in the form of ions due to electrochemical reactions, resulting in a lack of brightness on the surface of the electroplating workpiece, which compromises the aesthetics of the electroplating product.

[0005] What's more, if the electroplating solution uses an organic solution, the carbon content in the electroplating solution will be higher, and more carbon ions will be dissociated and deposited on the surface of the electroplated workpiece during the electroplating process, resulting in The appearance is carbon black, instead of the expected metal surface gloss, so it will not meet the appearance quality requirements of the current market for electroplated finished products
