Abstract
The utility model relates to a kind of micro-structural of roller, has roller; The outer peripheral edge of described roller is evenly equipped with microstructure unit, the adjacent spacing 25-100um of described microstructure unit; Described microstructure unit is semicircle or triangle or polygon; Solve the production cost that can not reduce light guide plate and the problem of enhancing productivity; Technique is simple, finished product yield is high.
Description
Technical field
The utility model belongs to electronics field, is specifically related to a kind of micro-structural of roller.
Background technology
Current light guide plate manufacturing technology is mainly divided into: injection moulding, and printing, hot pressing, ink-jet four kinds, wherein only has injection moulding can manufacture section micro-structure light guide plate by the mode of mould, and other three kinds of modes all cannot manufacture.But injection moulding production efficiency is very low, and equipment investment cost is very high, the production cost of light guide plate can not be reduced and enhance productivity.Another end face processing mode is processing micro structure above rectangular piece of stainless steel at present, by rectangular piece of stainless steel and light guide plate end contact, make microstructure transfer printing on piece of stainless steel on light guide plate, this kind of processing mode is too high to light guide plate flatness requirement, adds man-hour fraction defective too low.
Utility model content
The purpose of this utility model is to provide the micro-structural of the roller that a kind of technique is simple, finished product yield is high.
The technical scheme realizing the utility model object is: a kind of micro-structural of roller, has roller; The outer peripheral edge of described roller is evenly equipped with microstructure unit, the adjacent spacing 25-100um of described microstructure unit.
Preferred described microstructure unit is semicircle or triangle or polygon.
Preferred when described microstructure unit is semicircle, radius is 1-100um.
Preferred when described microstructure unit is triangle, drift angle is rounding, and rounding radii is 0.5-20um, and two base angles are 50-130 degree.
The utility model has positive effect: (1) this roller process technology technique is simple, and easy to operate, finished product yield is very high; Effectively can reduce the cost of whole backlight, and improve the production efficiency of light guide plate 3 times.
(2) steel plate is by chemical attack and laser mode processing micro structure, and is applied on roller, is heated to 60-120 degree by roller, and when light guide plate end face contacts with steel plate, light guide plate is heated and makes surface of steel plate microstructure transfer printing to light guide plate end face; By heating roller, the microstructure aspects on it is transferred to light guide plate end face, makes LED light increase into angular through the light guide plate end face of band micro-structural, solve because LED spacing causes greatly firefly phenomenon.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is a kind of structural representation of micro-structural of roller.
1 is roller, and 2 is microstructure units
Detailed description of the invention
See Fig. 1, the utility model has a kind of micro-structural of roller, has roller 1; The outer peripheral edge of described roller 1 is evenly equipped with microstructure unit 2, the adjacent spacing 25-100um of described microstructure unit 2.
Further described microstructure unit 2 is semicircle or triangle or polygon.
Further when described microstructure unit 2 is semicircles, radius is 1-100um.
Further when described microstructure unit 2 is triangles, drift angle is rounding, and rounding radii is 0.5-20um, and two base angles are 50-130 degree.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
