[0035] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0036] Electronic devices such as computers, mobile phones, and monitors will have logos on the display screen frame. Currently, the logos of product series on the display screen frame are usually printed with black high-gloss ink. High-gloss ink printing will have undesirable phenomena such as fat edges, pitting, and orange peel, and usually have poor quality. This embodiment of the electronic device takes a laptop as an example for description.

[0037] The present invention provides a process for preparing a display screen frame of an electronic device, comprising the following steps:

[0038] S1. Grinding and leveling the roller surface and then polishing it to prepare a high-gloss roller;

[0039] Specifically, the roller surface is first ground and leveled to remove impurities on the surface, and then the roller surface is polished to mirror level 14 to obtain a high-gloss roller.

[0040] S2, electroplating on the surface of the highlight roller to obtain a coating;

[0041] In one example, nickel is plated on the surface of a high-gloss roller to obtain a coating having a thickness of 8-10 μm;

[0042] The electroplating solution includes: nickel sulfate 250-350g / L, nickel chloride 35-40g / L, boric acid 40-50g / L, auxiliary brightener BNB-95A 8-12ml / L, brightener BNB-95B 0.5-0.8ml / L and pure water.

[0043] S3, polishing the surface of the coating, wherein the polishing thickness is less than the coating thickness;

[0044] In order not to damage the coating on the roller surface, the polishing thickness needs to be smaller than the coating thickness. The polishing thickness is preferably 4-5 μm, and the roller surface is polished to a mirror grade 14.

[0045] S4, preparing a logo on the polished coating;

[0046] Use a laser engraving machine with a power of no less than 1000W to laser engrave the logo on the polished coating. Compared with the ink printing method, laser engraving the logo with a laser engraving machine can not only shorten the process but also improve the quality of the logo.

[0047] In one example, in order to further improve the quality of the display screen frame, the display screen frame presents a fine texture to improve the quality of the electronic device product. Accordingly, the preparation process further includes:

[0048] Use a laser engraving machine to laser engrave textures on the coating outside the logo area, with the laser engraving energy being 80-160J.

[0049] Use a laser engraving machine with a power of 1000W or above to laser engrave the surface of the roller with the logo engraved on it, avoid processing the logo area, make the required texture, and adjust the required texture size through energy intensity.

[0050] S5, electroplating the surface of the roller with the prepared logo to obtain a logo roller;

[0051] In order to ensure the bright effect of the logo, electroplating is further carried out on the roller with the laser engraved logo. The concentration of the plating solution is 22-25%. The plating solution includes: nickel sulfate 250-350g / L, nickel chloride 35-40g / L, boric acid 40-50g / L, auxiliary brightener BNB-95A 8-12ml / L, brightener BNB-95B 0.5-0.8ml / L and pure water.

[0052] S6, heating the raw material of the display screen frame, extruding it through a Logo roller, cooling it, obtaining a raw material, and then cutting the raw material to obtain a display screen frame.

[0053] The raw material of the display screen frame is PC (polycarbonate) as an example. In one example, the display screen frame is obtained, including:

[0054] The raw material particles of the display screen frame are heated, dried and dehumidified, and then injected into the molding machine. After the raw material particles are melted, they are extruded through the screw, die head and mold, and then squeezed into sheets through the rubber roller and Logo roller. The temperature of the rubber roller and Logo roller is 260-300℃. During the molding process, the thickness of the sheet is controlled by the tightness of the roller pressure and the online thickness gauge.

[0055] A protective film is applied to the surface of the face frame raw material to obtain a face frame raw material with texture and logo; wherein the temperature of the cooling roller is 130-160°C;

[0056] According to the size of the display screen of the electronic device, the surface frame raw material containing the texture and the logo is cut to obtain the display screen surface frame.

[0057] The surface of the original face frame material is first covered with a PE protective film to facilitate CNC or die-cutting to the required size. After molding and before assembly, a CPP protective film is applied to protect the logo from getting dirty during subsequent processes and transportation.

[0058] The present invention provides an electronic device display screen frame and a preparation process thereof. First, a roller is ground, polished, and electroplated, and then the logo of the electronic device product series is directly laser engraved on the roller, and the roller with the logo is used as a mold. The roller with the logo laser engraved is electroplated again to keep the bright surface of the logo and protect the mold. In this way, when the raw material is formed, the display screen frame raw material with a bright surface logo can be directly formed. Finally, the display screen frame raw material is cut according to the size of the electronic device or the display screen, and a face frame with a bright surface logo effect is obtained after cutting. Compared with the printing technology in the prior art, the display screen frame with a bright surface effect prepared by the preparation process of the present invention has a better logo effect than that prepared by printing. The preparation process of the present invention replaces the traditional printing process and is applied to the entire series of products, which can not only save costs and processes, but also effectively save carbon emissions.

[0062] (2) Preparation of high-gloss roller: grinding and leveling the roller surface and then polishing it to mirror grade 14;

[0063] (3) Electroplating a highlight roller: nickel is plated on the surface of the highlight roller to obtain a nickel coating with a coating thickness of 8 μm;

[0064] The electroplating solution includes: 300g / L nickel sulfate, 35g / L nickel chloride, 45g / L boric acid, 8-12ml / L auxiliary brightener BNB-95A, 0.5-0.8ml / L brightener BNB-95B and pure water. The electroplating time is 12h.

[0065] (4) Polishing roller: polish the coating surface with a polishing thickness of 4 μm;

[0066] (5) The roller surface contains bright logo and texture: laser engraving is performed on the polished coating using a laser engraving machine. Figure 2 The logo "LEGION" is shown, and the laser texture is engraved again avoiding the logo area;

[0067] (6) The roller surface contains a protective coating: the roller surface with laser engraved logo and texture is electroplated again to obtain a logo roller, the logo roller surface contains a bright logo and texture;

[0068] (7) Molding: The raw material of the display screen frame is heated, extruded through a Logo roller, and cooled to obtain the raw material, which is then cut to obtain the display screen frame.

[0069] Comparative Example 1

[0070] A preparation process for a display screen frame, such as Figure 3 As shown, the following steps are included:

[0071] (1) Roller manufacturing: The roller is made of steel;

[0072] (2) Preparation of a high-gloss roller: grinding and leveling the roller surface and then polishing it to mirror grade 14 to prepare a high-gloss roller;

[0073] (3) Roller (with texture): Sandblast the surface of the high-gloss roller at a pressure of 6-8 kg to obtain a roller with texture;
