Embodiment Construction
[0040] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0041] see figure 1 , which is a schematic diagram of the manufacturing equipment of the flat display backlight functional module of the present invention. As shown in the figure, the manufacturing equipment of the flat display backlight functional module includes an injection rolling nozzle 200 and two counter-rotating rollers 100, and a certain gap is left between the rollers and the injection rolling nozzle (of course, the roller and the injection rolling nozzle Both can also be touched). When the raw material enters the space formed by the roller and the injection nozzle through the injection nozzle, after being rolled and pressed by the roller gap, a flat display backlight functional module is formed, which is peeled off with the rotat...

The invention discloses a manufacturing facility and a manufacturing method of flat panel display backlight function modules. The manufacturing facility comprises injection rolling mouths connected with an extrusion mechanism and two rollers rotating reversely, the surface of the rollers is provided with micro-structures; the roller and the injection rolling mouths are close or contacted, raw materials enter the space formed by the rollers and the injection rolling mouths through the injection rolling mouths, form a flat panel display backlight function module after the roll compacting of the roller clearance, and are peeled off with the rotation of the rollers. According to the manufacturing facility and the manufacturing method of flat panel display backlight function modules, injection molding mechanism and rolling molding are organically combined, compared with the existing injection molding technique, about over 20% to 80% of time is saved, simultaneously, the mould changing time is effectively shortened, automation rate is improved, labor cost is reduced, and damage of flat panel display backlight function modules with micro structures caused by human factors are avoided, accordingly, rate of finished products is improved, and flat panel display backlight function modules with micro structures and stable quality are manufactured.
Description
technical field [0001] The invention relates to the technical field of plane display, in particular to a manufacturing equipment and a manufacturing method of a backlight functional module of a plane display. Background technique [0002] As a special functional material, liquid crystal has extremely wide application value. With the emergence and development of various liquid crystal products based on liquid crystal display devices, liquid crystals have penetrated into all walks of life and every corner of social life. In recent years, liquid crystal display screens have become thinner and thinner, and the internal optical structures of flat-panel display modules have been continuously integrated into one board to reduce the volume. Flat display backlight functional modules with surface optical microstructures emerge as the times require, and there are various manufacturing methods, the most common method being injection molding. [0003] Injection molding is to melt the t...
