Rubber iron frame, back light, mobile terminal and rubber iron frame forming method

Abstract

The invention relates to a rubber iron frame, a back light, a mobile terminal and a rubber iron frame forming method. Specifically, the rubber iron frame comprises a rubber frame and a stainless steelback plate, a plurality of great wall positions extend from one end inner side of the rubber frame facing an LED light bar, the great wall positions are sequentially arranged, and a rubber reducing gap is reserved between every two adjacent great wall positions. On the basis, the rubber frame is relatively fixed on the surface of the stainless steel back plate by utilizing the plurality of divided great wall positions, due to the fact that the great wall positions are short, the glue consumption is small, and the pulling force generated in the contraction process is small, the deformation ofthe stainless steel back plate is reduced, the process of shaping a glue iron frame after forming by a glue-iron integrated shaping machine is omitted, and the cost is reduced. The problems that in the injection molding process, when the temperature is reduced to a normal temperature, due to plastic shrinkage, thin stainless steel, no enough strength support, a rubber iron frame just stripped froma mold is seriously warped, a rubber iron integrated frame shaping machine is generally used for shaping the rubber iron frame in the prior art to make up for the problem and the cost is high are solved.

Description

technical field [0001] The invention relates to the technical field of backlight sources, in particular to a rubber iron frame, a backlight source, a mobile terminal and a molding method for the rubber iron frame. Background technique [0002] The backlight (Back Light) is a light source located behind the liquid crystal display (LCD), and its luminous effect will directly affect the visual effect of the liquid crystal display module (LCM). Backlights are widely used in touch screens, backlights, LCD / LCM, mobile phones, tablet computers, GPS and solar cells and other industries; they are mainly composed of light sources, light guide plates, optical modules and structural parts; among them, the light sources mainly include EL, CCFL and LED backlight types; light guide plates are divided into printing, chemical etching (Etching), precision mechanical characterization (V-cut), light lithography (Stamper), internal diffusion, and hot pressing; optical dies: light-enhancing film ...

AI Technical Summary

Problems solved by technology

[0006] Based on this, it is necessary to address the above technical problems and provide a method capable of forming at least one rubber frame, backlight, mobile terminal and plastic frame, aiming at improving the shrinkage of the plastic when the temperature drops to normal temperature during the injection molding process. However, stainless steel is thin and does not have enough strength support, which leads to serious warping of the rubber iron frame just out of the mold. In the prior art, plastic iron frame shaping machine is usually used to make up for this problem, and the cost is relatively high.
