Step 3, prepare LGP
By the first mould 50 Rotate 180 degree, the first mould 50 and the second mould 60 is involutory in the second place on the 3rd surface 61 of the second mould 60, the second outstanding frame 54 of the second place on the 3rd surface 61 of the second mould 60 stretches into die cavity 51 inside that comprise backboard 2, the second base materials are injected in framework 3 and the second outstanding frame 54 inside in die cavity 51, make the second base material and framework 3 combinations, solidify the second base material, obtain that the second base material with framework 3 one forms LGP, because the first surface 11 of backboard 2 is provided with concave point 12, the surface of the LGP that such the second base material forms will form corresponding bump structure.
The embodiment of the manufacture method of backing structure of the present invention, wherein, for improving operating efficiency, production operation when can utilize two die cavities 51 on the second surface 57 of the first mould 50 to carry out two backing structures, when a backboard 2 is placed in a die cavity 51 of the first mould 50, while being prepared framework, another backboard 2 ' (now 2 ' for the formed backboard glue of completing steps two frame integrative-structure) is placed in another die cavity 51 of the first mould 50, the second outstanding frame 54 of the second place of the second mould 60 stretches in the die cavity 51 that comprises backboard 2 ', complete third step, backboard 2 ' is taken out after (ejecting), again by the first mould 50 Rotate 180 degree, while carrying out step 3 in backboard 2 is placed in another die cavity 51 of the first mould 50, another backboard 2 " be placed in a die cavity 51 of the first mould 50, the first outstanding frame 52 of the primary importance of the second mould 60 stretches into and comprises backboard 2 " die cavity 51 in, complete above-mentioned second step, with this, circulate, realize the manufacture of high efficiency backing structure.
The embodiment of the manufacture method of backing structure of the present invention, wherein, the curing shrinkage factor of the second base material is within the scope of 0.5%-0.7%.
The manufacture method of backing structure of the present invention adopts the solution of integrated injection moulding.
By glue iron integrated injection molding mode, complete the one-body molded of backing structure.Again by full-automatic production of realization that group film machine just can be real automatically.
Backing structure of the present invention by double-shot moulding, is molded over glue frame on backboard on the backboard of specially treated together with LGP.
High reflecting metal layer need to be plated in backboard inner side (with LGP to right face, i.e. first surface), thereby replaces traditional reflective sheet.
In the embodiment of the manufacture method of backing structure of the present invention, can be in backboard inner side (with LGP to right face, be first surface) silver-plated, after silver-plated, need to plate two-layer diaphragm, ground floor forms for being mainly Ti, Na or Nb (niobium), the in the situation that of in high-temperature atmosphere, by ground floor diaphragm, can well silver-colored reflectance coating and airborne oxygen and sulphur be separated, suppress oxygen reaction in silver and air; Second layer diaphragm is the oxides such as titanium oxide or zirconia, and Main Function is to improve reflectance coating heat resistance.The alternative reflector plate of this mode, saves cost.
Injection machine is double coloured plastic injection machine, a barrel is TPE material (for the preparation of framework), a barrel is transparent PC material (for the preparation of LGP), and this LGP injected plastics material need to be selected high shrinkage material (PC1500, the shrinkage factor of this material is at 0.5%-0.7%).Back plate surface is electroplated, and PC material is not easy to be combined with backboard, and after injection moulding completes, LGP can be filled air between backboard and LGP because shrinkage is separated with backboard, and the total reflection that is beneficial to LGP is carried out.
Frame material need to, with for example material of TPE, can well merge with PC and metal.Backboard metal used is combined by the mode of iron encapsulate with thermoplastic elastomer (TPE) (framework), and then utilize thermoplastic elastomer (TPE) to have can binding characteristic with PC material, again by PC in framework combination, metal (backboard), PC (LGP) and TPE (framework) just form an overall structure like this.
At the first surface of described backboard, a plurality of concave points being set can complete by punching press, is made in advance in diel and makes bump structure, is transferred in the first surface of backboard by punching press later.The first surface of backboard presents concave point, LGP injection moulding (light guide panel material need select high shrinkage material) on backboard after, the bottom side of LGP (contacting a side with backboard) can the corresponding bump structure that occurs, forms thus lattice point structure.
Framework (glue frame) and LGP, by double-shot moulding mode, are filled in backboard.This framework material need to, by the softwood matter that can follow PC or PMMA to merge, be beneficial to the effective integration with LGP and backboard.
Technical scheme dorsulum of the present invention, glue frame and LGP one-body molded, thus personnel's assembling procedure removed from, realize production of machinery.
Technical scheme of the present invention has the following advantages: integrated injection molding is removed the operation of personnel's assembling from, increases production efficiency, and saves production cost.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
