Abstract
The invention relates to a manufacturing method for a light guide plate mold insert. The manufacturing method comprises the following steps of: providing a cylindrical roller, wherein a layer of base membrane is plated on the outer peripheral surface of the roller; plating an intermediate layer on the surface of the base membrane; electroplating a layer of female die to be formed on the intermediate layer; carving a plurality of dots on the female die to be formed by using an electronic engraving technique, thereby obtaining a formed female die; stripping the formed female die from the roller and stretching into a flat shape; and copying a plurality of light guide plate mold inserts by using the formed female die and an electroforming method. Both of the electronic engraving and the electroforming methods are much more quickly than a laser processing method, therefore, production efficiency can be greatly improved according to the manufacturing method for the light guide plate mold insert.
Description
Technical field
The present invention relates to a kind of manufacture method of light guiding board mould core.
Background technology
Current light guiding board mould core is generally by the method manufacture of laser processing.But because the speed of laser processing is slow, if the light guiding board mould core of process larger sized needs the longer time of cost, efficiency ratio is lower.Simultaneously owing to can forming the chip of crateriform molten metal the site processing around after laser processing, thereby affect the planarization on light guiding board mould core surface, need to carry out the cleaning of long period, waste the plenty of time.
Summary of the invention
In view of this, be necessary to provide a kind of manufacture method of the light guiding board mould core that can effectively enhance productivity.
A manufacture method for light guiding board mould core, it comprises the steps: to provide a columned roller, is coated with a hypoglyph on the outer circumference surface of this roller; In the plated surface last layer middle layer of this counterdie; On this middle layer, electroplate one deck master mold to be formed; Use electronic engraving technology multiple sites of carve on this master mold to be formed, to obtain a moulding master mold; This moulding master mold is peeled off from this roller, and pulled into a tabular; Use electrocasting method, utilize this moulding master mold to produce multiple light guiding board mould cores.
Compared with prior art, the manufacture method of light guiding board mould core of the present invention, first forms a moulding master mold by the method for electronic engraving, then uses the method for electroforming, utilizes this moulding master mold to produce multiple light guiding board mould cores.Because the method for electronic engraving and electroforming is all a lot of soon than the method for laser processing, therefore can greatly enhance productivity.
Brief description of the drawings
Fig. 1 is the schematic diagram of the manufacture method of the light guiding board mould core of preferred embodiments of the present invention.
Fig. 2 is the schematic diagram that forms protective membrane in the manufacture method of light guiding board mould core of Fig. 1 on moulding master mold.
Main element nomenclature
Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1, the manufacture method of a kind of light guiding board mould core providing for embodiment of the present invention, it comprises the steps:
S1: a columned roller 10 is provided, is coated with a hypoglyph 20 on the outer circumference surface 101 of this roller 10.In the present embodiment, this counterdie 20 is copper film.
S2: in the plated surface last layer middle layer 30 of this counterdie 20.In the present embodiment, the material in this middle layer 30 is Silver Nitrate.
S3: electroplate one deck master mold 40 to be formed on this middle layer 30.In the present embodiment, this master mold 40 to be formed is made up of hard copper.In the present embodiment, the thickness of this master mold 40 to be formed is 150 microns (micrometer, μ m).
S4: use electronic engraving technology multiple sites 401 of carve on this master mold 40 to be formed, to obtain a moulding master mold 50.Electronic engraving technology is to utilize electronic engraving machine 402, according to photovoltaic principals, controls graver, in the technology of the required pattern of cylinder surface carve.The process velocity of electronic engraving is fast more a lot of than laser processing, and the chip carving out just can clean out by suction cleaner, does not need to carry out the cleaning of long period, and therefore working (machining) efficiency is effectively improved.
S5: mark an opening along being parallel to these roller 10 axial direction dues at this moulding master mold 50, thereby conveniently this moulding master mold 50 is peeled off from this roller 10, and pull into a tabular.This middle layer 30 makes to separate than being easier between this moulding master mold 50 and this roller 10.
S6: use electrocasting method, utilize this moulding master mold 50 to produce multiple light guiding board mould cores 80.Galvanoplastics is to utilize the electrolytic deposition principle of metal accurately to copy the physical process method of some complexity or special shape workpiece.The ultimate principle of electroforming is using the moulding master mold of making by desired shape in advance as negative electrode, as anode, together puts into the metal salt solution identical with anode material with electroforming material, passes to direct current.Under electrolytic action, moulding master mold surface deposits metal electric cast layer gradually, takes out after reaching required thickness from solution, and electroformed layer is separated with moulding master mold, just obtains the metal duplicate corresponding with moulding master mold shape.In the present embodiment, this light guiding board mould core 80 is made by nickel.Being appreciated that the plurality of light guiding board mould core 80 is respectively installed on multiple Jet forming machines (not shown) can produce multiple light guiding plates.
Shown in Fig. 2; in the present embodiment; in step S4, also comprise step: the method by electroforming forms layer protecting film 60 (such as nickel film) on this moulding master mold 50; prevent that this moulding master mold 50 from being scratched, thereby improve the product yield of the made light guiding board mould core of this moulding master mold 50 80.In step S5, in this protective membrane 60 is together with this moulding master mold 50, peel off from this roller 10.In step S6, need first this protective membrane 60 to be departed from from this moulding master mold 50, and then utilize this moulding master mold 50 to produce multiple light guiding board mould cores 80.In the present embodiment, the thickness of this protective membrane 60 is 1 μ m.Certainly, in other embodiments, this protective membrane 60 also can save.
Compared with prior art, the manufacture method of light guiding board mould core of the present invention, first forms a moulding master mold by the method for electronic engraving, then uses the method for electroforming, utilizes this moulding master mold to produce multiple light guiding board mould cores.Because the method for electronic engraving and electroforming is all a lot of soon than the method for laser processing, therefore can greatly enhance productivity.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to the claims in the present invention with distortion.
