Embodiment
Below in conjunction with the drawings and the specific embodiments light guiding film producing device and the method for making that the technical program provides is elaborated.
Referring to Fig. 1, the light guiding film producing device 100 that the technical program one embodiment provides comprises first delivery wheel 10, second delivery wheel 20, impression roller set 90, first template 50, second template 60, two coating units 70 and two solidification equipments 80.
See also Fig. 1 and Fig. 2, first template 50 is provided with first pattern transferring 51 of a plurality of array arrangements.In the present embodiment, this first pattern transferring 51 is a through hole.First template 50 and second template 60 all are circular, respectively around the side face 41 of the side face 31 that is fixed in first roller 30 and second roller 40.Second template 60 is provided with a plurality of array arrangements and second pattern transferring 61 spaced apart from each other.In the present embodiment, this second pattern transferring 61 is a projection.Each protruding 61 cross section is V-shaped.The spacing of every adjacent two projectioies 61 equates with the spacing of every adjacent two through hole 51.In addition, can directly link to each other between every adjacent two projectioies 61, promptly adjacent two projectioies 61 cooperate the formation v-depression.
Two coating units 70 relatively are located between first delivery wheel 10 and the impression roller set 90.Coating unit 70 can move around in the plane that is parallel to defeated material direction.The coating method of coating unit 70 can adopt but be not limited to the slit embrane method, scrape the skill in using a kitchen knife in cookery, method such as roller band glue or spraying.Two solidification equipments 80 also relatively are located between the impression roller set 90 and second delivery wheel 20.This two solidification equipment 80 can be light curring unit or thermal-curable system.
When using this light guiding film producing device 100 to make light guiding film, need at first provide substrate 15.These substrate 15 materials are high transparent plastic, as polycarbonate, polyethylene terephthalate, polymethylmethacrylate, or this area common plastics.After, this substrate 15 is delivered to second delivery wheel 20 by first delivery wheel 10 via impression roller set 90.Simultaneously, in this course of conveying, adopt relative two surface-coated first coat 25 and second coat 35 of this two coating unit 70 to substrate 15, and drive this two coating unit 70 and be parallel to the motion of defeated material direction, with smooth this first coat 25 and second coat 35.This first coat 25 and second coat, 35 materials can be polymethylmethacrylate, silica gel or epoxy resin.Be appreciated that, when first coat 25 during via first roller 30, first template 50 that is fixed in first side face 31 is depressed into predetermined thickness with this first coat 25, and in each through hole 51, form first pattern 45 with through hole 51 shapes and size, in the present embodiment, this first pattern 45 is cylindrical site.Meanwhile, second coat 35 is during via second roller 40, and second template 60 that is fixed in second side face 41 will form a plurality of and each protruding 61 shape and the second corresponding pattern 55 of size in second coat 35.In the present embodiment, this second pattern 55 is a groove.Each groove 55 is corresponding one by one with each site 45.After, when each projection 55 and each site 45 moulding that is cured during via solidification equipment 80, open light guiding film 65 greatly thereby make, and can pack up this light guiding film 65 by second delivery wheel, 20 rolling, be equipped with follow-up cutting according to actual needs.
This light guiding film producing device 100 directly with first template 50 and second template 60 respectively around being fixed in first roller 30 and second roller 40.When making light guiding film, can form site 45 and groove 55, save the plenty of time, enhance productivity greatly in the simultaneously disposable impression of defeated material.In addition, a plurality of grooves 55 will further improve light guide effect in the light guiding film 65 that makes.
In addition, first pattern transferring and second pattern transferring are not limited to structure shown in the present embodiment, and visual actual needs is done corresponding change.Distance also can be different from the spacing of adjacent two second pattern transferrings between adjacent two first pattern transferrings.
Be understandable that those skilled in the art also can do other variation etc. and be used for design of the present invention in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.The variation that these are done according to spirit of the present invention all should be included in the present invention's scope required for protection.
