Description

Technical Field

[0001] The utility model relates to the technical field of chemical nickel-gold plating, in particular to a novel roll-to-roll chemical nickel-gold roller device. Background Art

[0002] Chemical nickel-gold, also known as nickel-gold, immersion nickel-gold or electroless nickel-gold, is a process of replacing palladium on the surface of copper through chemical reaction, and then chemically plating a nickel-phosphorus alloy layer on the basis of the palladium core, and then plating a layer of gold on the surface of nickel through replacement reaction. Chemical plating has attracted increasing attention for its simple process, excellent uniformity and excellent reliability, and has become the development trend of global surface treatment technology. The roll-to-roll production process, that is, the continuous conveying roller production process, is widely used because it can improve the degree of production automation and production efficiency. Traditional roll-to-roll chemical nickel-gold equipment uses conveying devices such as guide rollers or rollers. Therefore, during the conveying process, the product will be damaged by contact with conveying devices such as guide rollers or rollers, which will affect the product quality and reduce the yield of the product.

[0003] In order to reduce the contact between the product and the roller and reduce the damage to the coating, the existing roll-to-roll chemical nickel-gold production equipment opens air holes on the roller and connects a high-pressure air pump. Under the action of air pressure, the product and the roller are practically transported without contact during the continuous production process. However, since the high-pressure gas is blown to the surface of the coating, it will cause problems such as oxidation and contamination of the coating surface, resulting in product quality problems. In addition, the roll-to-roll chemical nickel-gold production method also has problems such as inflexible equipment and difficult cleaning and maintenance during the production process. Therefore, we need to propose a new type of roll-to-roll chemical nickel-gold roller device. Utility Model Content

[0032] It is worth noting that the chemical plating solution can be heated by the heater 11;
