Problems solved by technology

Among them, the raw materials used for window lens IMD are PC / ABS (polycarbonate / acrylonitrile-butadiene-styrene copolymer), PMMA (polymethyl methacrylate) and in-mold transfer film, and the process is complicated. The molding yield rate is low, and the cost of raw materials, molds, and machines is high
In addition, the three independent manufacturing processes all require different moulds, machines, production sites and raw materials. The production investment is large, the cost is high, and the entire production time of the product is greatly extended due to transportation, storage and other expenses.

Embodiment 1

[0035] The basic structure and principle of the mobile phone in this embodiment are the same as those of the prior art, including panels, keyboards, display screens, and main circuit boards. In this way, the shell area and the window area of ​​the panel sheet are integrally formed, and the pattern color layer covers the shell area of ​​the panel sheet.

[0036] Such as figure 1 , figure 2 as shown, figure 1 It is a schematic cross-sectional view of the mobile phone panel in this embodiment, which adopts a single-layer single-material structure.

[0037] The manufacturing of the mobile phone panel in this example adopts the method of one-time molding of the panel sheet, and the panel sheet used can be APET (heat-shrinkable polyester), PETG (ethylene glycol modified-polyethylene terephthalate) ), PC, PS (polystyrene) and other materials. The panel sheet material is required to have excellent optical properties and stretchability, and the thickness of the panel sheet is abou...

Embodiment 2

[0054] The difference from the first embodiment is that the mobile phone panel of this embodiment has a keypad support.

[0055] The molded mobile phone panel, in addition to the outer casing part 10 and the window part 20, also includes a keypad bracket 31 for realizing key installation. Such as Figure 5 As shown, at the time of printing, except for the window portion 20, the keypad 30 of the panel sheet is also left blank. Such as Figure 6 As shown, after the panel sheet is formed by hot pressing, a part of the material of the keypad 30 is punched out using a corresponding punching die, so as to punch out the keypad bracket 31 .

[0056] It can be seen from the above specific implementation manners that the mobile phone panel manufacturing method of the present invention is simple and practical, and its molding process is conducive to the improvement of the yield rate, and can effectively save the cost of raw materials, molds and machine tools.

Abstract

The invention discloses a mobile phone and a mobile phone panel thereof, the mobile phone panel of the mobile phone comprises a panel sheet which is made of transparent materials and a pattern color layer, the panel sheet comprises a shell body region and a visual window region, and the pattern color layer is covered on the shell body region of the panel sheet. The invention simultaneously discloses a manufacturing method of the mobile phone panel, and the method comprises the following steps: A. the color and the pattern of the shell body region are printed on the panel sheet, and the visual window region is maintained to be transparent; B. the panel sheet is cut into sizes which are applicable to the shaping of the panel; C. the shaping of the panel is realized by a high-temperature and high-pressure mode. The manufacturing method of the mobile phone panel of the invention is simple and practical, the shaping mode thereof is conductive to the improvement of the product yield, thereby effectively saving raw materials and saving cost of a mold and a machine.

Description

【Technical field】 [0001] The invention relates to a mobile phone, in particular to a structure and a manufacturing method of a mobile phone panel. 【Background technique】 [0002] At present, the traditional injection molding process is generally used in the manufacture of mobile phone panels, including three independent manufacturing processes: injection molding of mobile phone casings, IMD (in-mold transfer injection molding) for window lenses, and bonding of casings and lenses. Among them, the raw materials used for window lens IMD are PC / ABS (polycarbonate / acrylonitrile-butadiene-styrene copolymer), PMMA (polymethyl methacrylate) and in-mold transfer film, and the process is complicated. The molding yield rate is low, and the cost of raw materials, molds, and machines is high. In addition, the three independent manufacturing processes all require different moulds, machines, production sites and raw materials. The production investment is large, the cost is high, and the ...
