Description

Technical Field

[0001] The invention relates to the technical field of gold plating, in particular to a gold plating device. Background Art

[0002] Gold plating is a process of plating a thin layer of gold on the surface of an object, mainly used for decoration and protection. Gold plating not only gives the product a unique appearance and performance, but also increases the product's attractiveness and value. Gold plating methods can be divided into electroplating and chemical gold plating. Chemical gold plating is a surface treatment technology that uses a chemical reducing agent to reduce gold ions in a gold salt solution into metallic gold and deposit it on a substrate. It is not limited by the shape of the substrate and can form a uniform and dense coating on both flat and curved surfaces. By adjusting the composition of the plating solution and the process parameters, the thickness of the coating can be precisely controlled to meet different application requirements. The coating and the substrate are tightly bonded through chemical reactions and are not easy to fall off, which reduces the emission of harmful substances and is more environmentally friendly. Gold plating can effectively extend the service life of the material and can make the surface of the object It presents a golden color, which increases the beauty and visual effect of the object and can greatly reduce the production cost, because only a thin layer of metal needs to be covered on the surface to achieve an appearance similar to that of solid metal. For high-precision devices such as electronic components, gold plating can form a dense oxide layer on the surface, improve the electrical properties of electronic components, prevent the metal surface from being oxidized, ensure the stable operation of components, and improve electrical performance. After the metal material is gold-plated, a dense oxide layer can be formed on its surface, which can prevent the metal from being oxidized in the air, has strong corrosion resistance and oxidation resistance, and greatly improves the durability and stability of the material. Therefore, a gold plating device is needed.

[0003] When operators perform gold plating on workpieces, they often use corresponding gold plating devices. When gold plating is performed, electroplating and chemical gold plating are mostly adopted. When chemical gold plating is performed, it is often necessary to manually place the gold-plated workpiece in the solution and then clean it and air-dry it. This operation method increases the labor intensity of the operators, which may reduce the efficiency of gold plating. In addition, when gold plating is performed, it is necessary to frequently manually take and lift between the gold plating solution and the cleaning solution, and the workpiece needs to be manually fixed when clamping it, and the degree of automation is low.
