Description
Technical field
The present invention relates to light guide plate processing technique field, the processing method of more particularly to a kind of Wedge shape light conduction board and for giving birth to
Produce the pressure roller group of Wedge shape light conduction board.
Background technology
Light guide plate is a kind of acrylic PMMA (polymethyl methacrylate)/PS (polystyrene)/MS (poly- third of optical grade
Olefin(e) acid ester)/PC (but being not limited to above material) sheet material, there is the characteristics of high reflectivity and not extinction, be widely used in LCD
On (LCDs) and LED (light emitting diode) display screen, it draws what is issued from lamp using optical grade acryl plates
Light, when light is mapped to each light guiding points, reflected light can spread toward all angles, then be projected by light guide plate front, by each
Kind density, light guiding points not of uniform size, can make light guide plate uniformly light-emitting, realize line source being converted to area source.
Existing Wedge shape light conduction board is fabricated by the way of ejection formation mostly, and its principle is Jet forming machine by optics
Level PMMA/PS/MS/PC (but being not limited to above material) particle is injected in mould and is cooled and shaped with high temperature, high pressure.It is general next
Say, the Wedge shape light conduction board of injection type easily produces burr, easily produces and is molded irregular situation, causes Stress non-homogeneity, soft
Toughness is poor, easily loses during bending, and briliancy is low, and product yield is low, and particularly die cost is very expensive, as long as the conversion angle of chamfer
Degree and product size etc. then have to open different moulds again, and die cost is high and pretty troublesome.
The content of the invention
The invention provides a kind of processing method of Wedge shape light conduction board and the pressure roller group of angle adjustable, as long as adjustment pressure roller group
Roller between angle and the distance between roller, you can realize the Wedge shape light conduction board of different bevel angles and different thick
The production of the Wedge shape light conduction board of degree, it is not necessary to mould is all opened up for the light guide plate of each specification, substantially reduces production cost, and
And continuous production, stable production process, efficiency high can be realized.
In order to solve the above technical problems, one aspect of the present invention is：A kind of adding for Wedge shape light conduction board, is provided
Work method, carry out in accordance with the following steps：
Step S1. will be melt into liquid resin for the solid feed for processing light guide plate；
The resin of liquid is extruded to pressure roller group, the pressure roller group and is provided with least one set by step S2. using plastic extruder,
Every group of pressure roller group all includes the first roller and the second roller being not parallel to each other, and has folder between the first roller and the second roller
Angle, extruded by the first roller and the second roller when the liquid resin is through between the first roller and the second roller, formed after cooling
Wedge shape light conduction board.
Further say, the adjustable angle of the angle between first roller and second roller.
Further say, the light guide plate is the Wedge shape light conduction board that section is right-angled trapezium；In step S2, first roller
Cylinder and second roller are all cylinder.
Further say, the light guide plate includes the wedge-shaped light guide section that section is right-angled trapezium and positioned at the wedge shape leaded light
At least entering light adjustment portion of side in the height both sides in portion, the rectangular cross-section of the entering light adjustment portion；
In step S2, first roller is cylinder, and the centre of second roller is cylinder, and second roller
End forms the round platform to match with the entering light adjustment portion of the light guide plate.
Further saying, in step S2, the pressure roller group includes the first roller, the second roller and third roll, and described
Two rollers and the third roll are symmetrical arranged；The liquid resin first passes through tentatively shapes between the first roller and the second roller
Again by being shaped again between the first roller and third roll, light guide plate is formed.
Further say, in step S2, the surface of at least one of both described first roller and second roller
Provided with decorative pattern, the liquid resin passes through between the first roller and the second roller, and the decorative pattern is suppressed in the table of the light guide plate
Face forms guide-lighting decorative pattern and forms continuous light guide plate, afterwards the light guide plate of size needed for cleaved formation.
Further say, in step S2, the surface of first roller and second roller is all shiny surface, the liquid
Body resin is by forming continuous and smooth surface light guide plate between the first roller and the second roller；Size needed for cleaved formation afterwards
Light guide plate.
Further say, under at least one side of the light guide plate of the smooth surface has guide-lighting decorative pattern, and the guide-lighting decorative pattern is
One kind in three kinds of structures of row：
First, the guide-lighting decorative pattern is in the decorative pattern on the surface of the light guide plate by laser dotting technological forming；
2nd, the guide-lighting decorative pattern is the decorative pattern on the surface that the guide-lighting laminate is taken shape in by printing ink printing art；
3rd, the guide-lighting decorative pattern is the embossing technological forming by hot pressing in the decorative pattern on the surface of the light guide plate.
Further say, the entering light adjustment portion is provided with two, and is respectively the of the low avris positioned at wedge-shaped light guide section
Second entering light adjustment portion of one entering light adjustment portion and high avris positioned at wedge-shaped light guide section；
In step S2, first roller is cylinder, and the centre of second roller is cylinder, and second roller
One end forms the round platform to match with the first entering light adjustment portion of the light guide plate, and the other end is also formed to be entered with described second
The round platform that light adjustment portion matches.
