Embodiment
Below in conjunction with accompanying drawing the present invention being done one specifically introduces.
See also Fig. 1, be depicted as the synoptic diagram of the light guiding film manufacturing installation 100 of first embodiment of the invention, this light guiding film manufacturing installation 100 comprises that a 10(of feed portion is reciprocating type dispense tip herein, can be scraper in other embodiments), first roller 20, second roller 30, a pinch roller 40 and a reel 50.
This feed portion 10 is used for supplying with the starting material of making light guiding film 200, and in the present embodiment, the starting material of light guiding film 200 are the UV resin 12 of molten condition.This feed portion 10 roughly is a funnel-form, and it comprises charging aperture 102 and corresponding discharge nozzle 104, and UV resin 12 enters this feed portion 10 from this charging aperture 102, and flows out along this discharge nozzle 104.
In the present embodiment, this first main body 22 and second main body 32 are the hollow cylinder that adopts quartz material.Quartz material can allow the UV light transmittance of 365nm wavelength around more than ninety percent.This first main body 22 and second main body 32 are installed on respectively on the fixing rack structure 222, and fixing rack structure 222 does not rotate with the rotation of first main body 22 and second main body 32.
This first roller 20 and second roller 30 impress the UV resin 12 that flows into this shaping channel 103 respectively, and this first microstructure 242 and this second microstructure 342 are transferred to 12 two outside surfaces of this UV resin.
Present embodiment is in order to make the 12 two-sided curing more equably of UV resin, at this first roller 20 and second roller, 30 inside a UV light source 60 is installed respectively, this UV light source 60 is installed on the fixing rack structure 222, namely this UV light source 60 is with the rotation campaign of this roller, and the direction of illumination of this UV light source 60 is all the time towards another roller.Be appreciated that if consider the cost problem, also UV light source 60 can only be installed in this first roller 20, or UV light source 60 only is installed in this second roller 30.When in this first roller 20 UV light source 60 being installed, this UV light source 60 is all the time towards this second roller 30; When in this second roller 30 UV light source 60 being installed, this UV light source 60 is all the time towards this first roller 20.
This pinch roller 40 is arranged at the below of this second roller 30, is used for guiding and pressing light guiding film 200 to change light guiding film 200 outbound courses and to prevent that light guiding film 200 is in the distortion of transport process.This pinch roller 40 is cylindric, and its central shaft is parallel to the central shaft of this second roller 30, and this pinch roller 40 can roll along its central shaft.Light guiding film 200 after the light guiding film 200(that this reel 50 passes through pinch roller 40 for reeling namely solidifies, is shaped).
See also Fig. 2, be the process flow diagram of light guiding film manufacture method of the present invention, it comprises the steps:
S21 is positioned over the UV resin 12 of fusion in the feed portion 10, and the UV resin 12 that makes fusion flows out along the discharge nozzle 104 of feed subordinate side;
S22, first roller 20 and this second roller 30 are rolled along the direction of arrow shown in Figure 1 respectively, and make the UV light source 60 that is arranged in first roller 20 and second roller 30 send UV light, UV resin 12 flow to the irradiation area of UV light source and the shaping channel 103 between first roller 20 and second roller 30 successively along discharge nozzle 104, when UV resin 12 solidifies, first roller 20 and second roller 30 impress the UV resin 12 in the shaping channel 103 respectively, at this moment, first microstructure 242 and this second microstructure 342 are transferred to two outside surfaces of this UV resin 12 respectively, form light guiding film 200.
S23 provides a pinch roller 40, be used for after light guiding film 200 forms, being wound take turns 50 roll before, this light guiding film 200 of pressing is to prevent the distortion of light guiding film 200 in transport process.
S24 provides a reel 50, in order to the light guiding film 200 of the solidified forming of reeling.
In said method, this first roller 20, this second roller 30 and this reel 50 all can be driven by the motor (not shown), its rotating speed is coordinated mutually, so that this manufacturing after being shaped light guiding film 200 unlikely tensions or excessively pine be advisable, the coating speed of this feed portion 10 is coordinated mutually with the rotating speed of this first roller 20, this second roller 30 and this reel 50, with the uniform UV resin 12 of coating thickness.In the present embodiment, this first roller 20 clockwise rotates, and this second roller 30 rotates counterclockwise, and this reel 50 rotates counterclockwise.In addition, when making light guiding film 200, the viscosity of this UV resin 12 will make it can break away from this first roller 20 and this second roller 30 smoothly after curing, owing to need not use carrier, therefore, the allotment of the viscosity of this UV resin 12 is more easy.
See also Fig. 3, it is the synoptic diagram of the light guiding film manufacturing installation 110 of second embodiment of the invention.The light guiding film manufacturing installation 110 of second embodiment is similar with the light guiding film manufacturing installation 100 of first embodiment, its difference is that the feed portion 10 of this embodiment is accurate coating machine (Slot Die), to be easier to controlling diaphragm thick because of accurate coating machine ratio, so adopt vertical mode to install at this first roller 20 and second roller 30, namely first roller 20 be positioned at this feed portion 10 under, second roller 30 be positioned at first roller 20 under and with this first roller 20 preset distances at interval.When making light guiding film 200, the UV resin 12 of molten is from flowing to after feed portion 10 flows out on first roller 20 and along with the rotation of first roller 20 moves between first roller 20 and second roller 30.Because the feed portion 10 coated film layer thicknesses of accurate coating machine are generally tens of microns, therefore, before entering shaping channel 103, be coated on that UV resin 12 on first roller 20 still can be adsorbed on first roller 20 basically and unrestrained.Light guiding film manufacturing installation 110 remaining structure and manufacturing process can here just repeat no more with reference to first embodiment in the present embodiment.
This light guiding film manufacturing installation and manufacture method make UV resin 12 directly in shaping channel 103 by the duplex transfer printing pattern, avoided use PET thin-film carrier, be conducive to further reduce the thickness of light guiding film 200, thereby promote light leading diaphragm slimming degree, light transmittance and light guide effect.
Be understandable that those skilled in the art also can do other variation and wait 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 within the present invention's scope required for protection.
