Embodiment 1

[0018] The electroplating method for the face shell of the display device includes the following steps: (1) ultrasonic cleaning, adding a cleaning agent to hot water, and cleaning the plated parts in an ultrasonic environment; (2) anode electrolysis, adding Degreasing powder, electrolytically degreasing and / or dewaxing the plated parts, and then washing with water; (3) derusting the plated parts with hydrochloric acid, and then washing with water; (4) cathodic electrolysis, adding degreasing powder in water, The plated parts are deoxidized by cathode electrolysis, and then washed with water; (5) nickel plating, put the plated parts into hot water, and add nickel sulfate with a concentration of 200g / t, nickel chloride at 55g / t and 50g / t at the same time. The boric acid of t carries out electroplating, then cleans with water; (6) copper plating, plating part is put into water, adds concentration and is the copper sulfate of 200g / t, the sulfuric acid of 70g / t carries out electropl...

Embodiment 2

[0029] In step (6), copper plating can also be replaced with black nickel plating, and black nickel salt with a concentration of 150g / t is added to the plating tank at a temperature of 55°C. After washing twice with water, the surface of the display device presents a black metal texture effect.

Embodiment 3

[0031] In step (6), it is also possible to replace the copper plating with nickel plating. Adding concentrations of 200g / t nickel sulfate, 55g / t nickel chloride, and 50g / t boric acid into the plating tank respectively After 10 minutes of electroplating, pick up the water and wash it 3 times, so that the display device surface shell has a silver metal texture effect.

Abstract

The invention provides a method for electroplating a face shell of display equipment. The method comprises the following steps of: (1) performing ultrasonic cleaning, namely adding a cleaning agent and cleaning a plated part in the ultrasonic environment; (2) performing anode electrolysis, namely adding oil removal powder, and performing electrolysis on the plated part to remove oil or wax, and cleaning; (3) removing rust from the plated piece by using hydrochloric acid, and cleaning; (4) performing cathode electrolysis, namely adding oil removal powder, performing cathode electrolysis on a cathode of the plated part to remove an oxidized film, and cleaning; (5) plating nickel, namely adding 200g / t nickel sulfate, 55g / t nickel chloride and 50g / t boric acid for electroplating, and cleaning; and (6) plating copper, namely putting the plated part in water, adding 200g / t copper sulfate and 70g / t sulfuric acid for electroplating, and cleaning. The method has the advantages that a high-end strong rose gold texture surface effect can be achieved by face shells of the display equipment such as televisions, advertising machines, touch screens, monitors and displayers.

Description

【Technical field】 [0001] The invention relates to an electroplating method, in particular to an electroplating method for a display device cover. 【Background technique】 [0002] The display devices on the market today, such as TVs, advertising machines, touch screens, monitors, monitors, etc., are basically made of plastic or unplated metal, which looks poor in color, lacks texture, and is not high-end. 【Content of invention】 [0003] The object of the present invention is to provide an electroplating method that can obtain a rose gold texture surface effect on the surface shells of display devices such as televisions, advertising machines, touch screens, monitors, and displays.
