Embodiment
See Fig. 1 to Fig. 8, below in conjunction with accompanying drawing, the present invention is described in detail.
A kind of guide structure of the present invention, include support, also include light guide body 1, described support is metal support 2, described light guide body 1 is the light guide body 1 adopting high temperature resistant material to make, metal support 2 inserts in the colloid forming light guide body 1, forms light guide body 1 and links all-in-one-piece guide structure 3 with metal support 2; Wherein, described metal support 2 is being provided with binding end 21 with connector shell 4 junction.In the present invention, inventor passes through Creative Thinking, change the PC plastics that current light guide body 1 generally adopts, resistant to elevated temperatures material is used for light guide body 1, thus replace the material of the PC plastics that current light guide body 1 uses, and be equipped with metal support 2 and be connected with connector shell 4, guide structure 3 thermotolerance produced by said structure is strong, the phenomenon of melting is there will not be in the pyroprocess that light guide body 1 is heated, thus the quality of LED is ensured, there will not be the phenomenon of dead lamp, light-out effect is good, and effectively improve the aesthetic feeling of whole product.
As preferred embodiment, the high temperature resistant material that described light guide body 1 adopts includes epoxy resin and rigidizer.Material that this is high temperature resistant is the high performance lED liquid type potting resin for characteristic institute development & production such as resistance to UV, high Tg, high transmission rate and sealings, and for day by day strict European Union environmental protection requirement, the high temperature resistant material that the utility model adopts also can meet as Rohs, HalogenFree([Br completely] <900ppm, [CI] <900ppm, [Br]+[CI] <1500ppm) etc. requirement.
As everyone knows, PC plastics due to viscosity not high, various difform light guide body 1 can be formed with the installation of matching connector housing 4 by the mode such as injection moulding or ejection formation, but the high temperature resistant material after improving includes epoxy resin and rigidizer, because epoxy resin has superpower toughness, injection moulding or ejection formation cannot be adopted as PC plastics to become the light guide body 1 of various shape, can be combined with connector shell 4 for ease of the light guide body 1 after improving, the present invention by arranging a metal support 2 in light guide body 1, be combined with connector shell 4 by this metal support 2.Guide structure 3 of the present invention includes and adopts the light guide body 1 that high temperature resistant material is made and the metal support 2 be combined with connector shell 4, not only solve light guide body 1 to be heated the problem of easy softening transform, and this metal support 2 is by arranging a binding end 21, simultaneously at connector shell 4 to molding button bit 41 in binding end 21 place, when light guide body 1 coordinates with LED pin, LED pin and light guide body 1 is facilitated to position, this metal support 2 can also effectively solve light guide body 1 and connector shell 4 in conjunction with problem, convenient and practical, marketable value is huge, social agency is obvious, be worthy to be popularized.In the present invention, the embodiment of this binding end 21 set by metal support 2 can for as shown in Figure 1 offer one in " ㄩ " shape or the opening of other shapes, or the embodiment of this binding end 21 also can for as shown in Figure 2 offer a rectangular closed notch, can also be the closed notches such as circle, triangle, as long as the function realizing light guide body 1 and connector shell 4 being carried out combining can be convenient to.
Further, described light guide body 1 is being provided with locating piece 11 with connector shell 4 joint.In the present invention, by arranging locating piece 11 in described light guide body 1 with connector shell 4 joint, be convenient to position when light guide body 1 is assembled with LED, installation process is simple and convenient.
The method for making of a kind of guide structure of the present invention, includes following steps:
(1), glue is joined: extraction includes epoxy resin, the high temperature resistant material of rigidizer stirs, and forms glue;
(2), mould bar 5 installs: getting out be provided with the mould bar 5 of light guide body model 6 and the aluminum ship for installing mould bar 5, being fixedly installed in aluminum ship by the mould bar 5 being provided with light guide body model 6, and pushed in glue pouring machine by mounted mould bar 5 and carry out preheating;
(3), spray from: release agent is sprayed to mould bar 5 inside of preheating;
(4), encapsulating: the glue prepared is injected to mould bar 5 inside of having sprayed release agent;
(5), insert support: inserted in the mould bar 5 filling glue by qualified metal support 2 and encapsulate, form the encapsulating structure that light guide body 1 is combined with metal support 2, wherein, one end that metal support 2 injects glue is provided with through hole;
(6), solidify: the encapsulating structure being plugged metal support 2 is pushed in glue pouring machine again and carries out baking primary solidification;
(7), from mould: through the encapsulating structure that light guide body 1 is combined with metal support 2 being separated from mould bar 5 from mould station;
(8), shear: the redundance of metal support 2 is excised from the encapsulating structure that light guide body 1 is combined with metal support 2, form guide structure 3, described guide structure 3 includes light guide body 1, described light guide body 1 is being inserted with metal support 2 with one end that connector shell 4 is combined, and described metal support 2 is provided with the binding end 21 be combined with connector shell 4.
Further, also include step (9), described step (9) is carried out row to the guide structure 3 obtained in step (8) and is surveyed, and removes unacceptable product.
In the present invention, in described step (1), the composition of glue mainly includes epoxy resin and rigidizer, certainly, can also include toner, diffusant etc., be carried out by weight stirring by mentioned component when joining glue; Wherein, spray release agent in step (3) to mould bar 5 inside of preheating, to be that support in order to allow encapsulating complete is easier carry out from mould in its effect, avoids glue bond with mould bar 5 after solidification and damage product.
Further, in step (1), obtained glue is put into vacuum drier and is carried out heating vacuum deaeration, prevents having bubble to produce in the glue configured; In step (2), the mould bar 5 being fixedly installed in aluminum ship pushes in glue pouring machine and carries out preheating, avoids glue to produce bubble in encapsulating process, affects the shaping of light guide body 1, thus affects the brightness of guide structure 3 of the present invention and the angle of bright dipping; In step (5), after metal support 2 inserts and completes encapsulation in the mould bar 5 filling glue, then metal support 2 is pressed down, further metal support 2 is inserted into position, ensures the quality of production of guide structure 3 of the present invention.
Again further, in described step (7), when the encapsulating structure of light guide body 1 and metal support 2 after separating from mould station from mould bar 5, put into baking oven and carry out Post RDBMS.In the present invention, fully solidified to allow epoxy resin, also heat ageing is carried out to product simultaneously, the present invention is after completing from mold process, further light guide body 1 is put into baking oven with the encapsulating structure of metal support 2 and carry out Post RDBMS, thus improve the bond strength of epoxy resin and metal support 2.
The foregoing is only the present invention's comparatively preferred embodiment, and be not used to limit practical range of the present invention, therefore any do not depart from the present invention design prerequisite under any apparent replacement all within protection scope of the present invention.
