Problems solved by technology

[0004] Due to the characteristics of the production process and the characteristics of the surface coating on the surface of the existing coated metal plate, the front part of the surface cannot be electrically conductive after surface coating
[0005] The production of existing computer cases, such as using the traditional process of forming first and then spraying powder or painting, has complicated procedures, and the process of powder spraying or painting will cause serious pollution, and increase the manufacturing cost, and the final product after forming It is prone to dusting or uneven painting, making the appearance of the product rough

Abstract

The invention discloses a method for processing a coated metal plate, which comprises the following steps: performing surface chemical treatment on the facade of a substrate; coating a coating on the part outside edge areas of two opposite sides on the surface of a chemical treatment layer; and simultaneously coating a conductive coating on the rear of the substrate. The invention provides the method and a device for processing the coated metal plate, which are used for producing coated metal plates for shells of products such as computer cases subjected to an electromagnetic interference test.

Description

technical field [0001] The invention relates to a method for processing a coated metal plate, in particular to a method and equipment for processing a coated metal plate used for an electrical appliance housing that needs to be tested for electromagnetic interference of the whole machine. Background technique [0002] Traditional coated metal sheets include substrates, which can be made of steel sheets such as cold-rolled sheets, electro-galvanized sheets, hot-dip galvanized sheets, and galvanized sheets. There are chemically treated layers on the front and back of the substrate, and the chemically treated layers The outer layer has a paint protection layer. As the casing of household appliances, this kind of coated metal plate has no pollution to the environment, and is widely used in refrigerator casings, refrigerator side panels, microwave oven casings, air conditioner casings, washing machine casings and other products. However, since the surface of the traditional coat...
