Description of drawings
Be further to disclose concrete technology contents of the present invention, carry out below that embodiment and accompanying drawing describe in detail as after, wherein:
Fig. 1 is known light guide plate modular structure figure;
Fig. 2 is the sectional drawing after light guide plate module of the present invention is shaped;
Fig. 3 is the schematic flow sheet of manufacture method of the present invention.
Embodiment
As shown in the figure, basically, manufacture method of the present invention is by a kind of material preparation step 1, and pressing steps 2, one cooling press rib steps 3 and/or a cutting step 4 are formed altogether.
Wherein, material preparation step 1 is for preparing the required material of optical waveguide layer A respectively, and it is with the clear, colorless macromolecular material, as acryl, PC etc. are good, only not as limit, and it can be inserted among the hopper A1, for the usefulness of extruding, and this extruding is a known technology, so do not intend giving unnecessary details, the material of diffusion layer B, then for being same as the material of the optical waveguide layer A that advances, only it adds light diffusing agent, and this light diffusing agent can be as titania (TiO
2), lime carbonate (CaCO
3), silicon dioxide (SiO
2), alundum (Al (Al
2O
3) ... etc. small heat-resistant particles, then, then insert in the hopper B1, for its extrusion modling; Prism lamella C is the transparent polymer material, its preferably with optical waveguide layer A, B identical materials, only also can be other transparent polymer materials material C placed in the hopper C1.
Co-extrusion pressure step 2 is the layers of materials of being ready for aforementioned, behind extruder A2, B2, C2 difference heating and melting, sends into co-extrusion pressure die head D extrusion modling, makes three layers to integrate, and forms the stock of integrated slice plate body.
Cooling press rib step 3 be with aforementioned by extrude one-body molded of die orifice stock, cooling wheel E1, E2, E3 through adjacent retrograde rotation each other press cooling mutually, wherein, on cooling wheel E2 that rhombus lens layer C contacts, must be carved with the prism rag, therefore normal stock by the time, then via the pressurization embossing of the prismatic rag of cooling wheel E2, make prism lamella C form the prism F of portion, promptly form outboard profile as shown in Figure 2.
Cutting step 4 is intended to cutting of size for light guide plate module that tool prismatic that will obtain is carved grave, and only this is a known technology, so do not give unnecessary details.
Actually, during with this co-extrusion pressure mode moulding, if optical waveguide layer, when diffusion layer is unlike material with the prism lamella, then can press from both sides with the now material therebetween and be the common mode extrusion, like this, also can get the stock that five-layer structure is formed in one, then, give the cooling press rib again.
And that the sheet material of cooling press rib step pin 3 carries out with processing mode is a lot of, is not limited to embodiments of the invention, forms effective prismatic rag making only basically.
So, via enforcement of the present invention, it is with the formed light guide plate module of one-body molded mode, on adaptation, oneself knows that laminating type is good certainly, and exempts the shortcoming improperly of fitting, especially, cost of manufacture is low, and even in scheduling of production and the allotment, also need not for each layer stock or half-finished stock with allot.
Disclosed, be that preferred embodiment is a kind of, the change of every part or modification and come from technological thought of the present invention and be ripe stay that this skill carves the people was easy to know by inference, all do not take off patent right category of the present invention.
