Abstract
The invention discloses a manufacturing method of a glass grating, comprising the following steps of: step 1, horizontally placing a glass with clean surface on a lower mould frame of a grating mould, placing an upper mould frame of the grating mould above the glass, and making the upper mould frame near the glass and have certain distance from the surface of the glass, keeping four sides of the upper and lower mould frames of the mould sealed; step 2, heating the upper and lower mould frames of the mould, then, moving the upper mould frame downwards, stamping the surface of the glass by the mould at the lower surface of the upper mould frame to process the surface of the softened flat glass to be grating-shaped; and step 3, naturally annealing to normal temperature, opening the mould, and demoulding to get the glass grating. A column mirror grating manufactured by the method has wide selection range of refractive index, and a glass column mirror grating manufactured by the method is excellent in surface smoothness, high in precision and high in uniformity, and can be used in naked-eye stereoscopic display equipment.
Description
Technical field
The invention belongs to the optics manufacture field, relate in particular to a kind of making method of glass raster.
Background technology
In stereo display technique, especially in the bore hole stereo display technique, the use of column mirror grating more and more widely, the production technique of column mirror grating mainly contains three kinds at present: one, utilize the UV light binding to prepare the glass column mirror grating in the glass surface moulding; Two, utilize the glass calendering technology to prepare the glass column mirror grating; Three, utilize the molded preparation column mirror grating of plastic roller.The glass column mirror grating of first kind of prepared is simple, convenient, but the glass column mirror grating of processing be prone to come off, damage resistant not, long grating layer of time is prone to turn to be yellow; Though the glass column mirror grating of second kind of prepared solved first kind of technology be prone to come off, not damage resistant, be prone to shortcoming such as jaundice, glass column mirror original screen panel warpage, surface irregularity and the thickness that this prepared goes out shortcoming such as can not process less than the glass of 3mm.Though the column mirror grating planarization of the third prepared is good, precision is high, and light transmission is bad, yielding for a long time, easy jaundice.
Summary of the invention
The purpose of this invention is to provide a kind of making method of making the glass raster simple, that quality product is high.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of making method of glass raster comprises the steps:
Step 2, with the up and down framed heating of mould, make framed moving downward then, the die stamping glass surface of last framed lower surface makes the remollescent surface of plate glass become raster shape;
Step 3, be annealed to normal temperature naturally, the breakdown mold releasability, glass raster.
The temperature of framed up and down with the grating mould in the said step 2 is heated to 600 ℃-800 ℃.
Said grating mould comprises framed and low mold frame; Upper and lower framed being fastened and connected gone up framed lower surface and is provided with mould, around the mould and gapped between the patrix edge frame; The mould lower surface of going up framed lower surface is a column nick type array, and the low mold frame upper surface is a smooth flat.
Said framed material up and down is a steel alloy.
This process using hot stamping forming method is made glass raster, and simple to operate, production cost is low; Produce applied widelyly, can process glass (post mirror) grating of all thickness, (post mirror) the optional scope of grating index that can make is big, and the surfacing of the glass of producing (post mirror) grating, precision are high, good uniformity.
Description of drawings
Fig. 1 is a step 1 structural representation of the present invention;
Fig. 2 is a step 2 structural representation of the present invention;
Fig. 3 is a step 3 structural representation of the present invention.
Embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, preparation method of the present invention comprises the steps:
Step 2, as shown in Figure 2; Electric heating through the grating mould is heated to 690 ℃ with upper and lower framed 1,2 the temperature of mould, makes glass surface softening, makes framed 1 to move downward slowly then; Punching press glass 3 surfaces make the remollescent surface of plate glass form the column raster shape;
Step 3, as shown in Figure 3 is annealed to normal temperature naturally with whole grating mould, and the breakdown mould carries out the demoulding, takes out glass raster;
Step 4, detect the planeness and the slickness of glass raster, if the qualified finished product that is defective, polishes the level of making it with polishing machine to glass raster.
Among the present invention; The grating mould comprise framed 1 with low mold frame 2; Upper and lower framed 1,2 are fastened and connected, and go up framed 1 lower surface and are provided with mould 11, around the mould 11 and gapped between last framed 1 the frame; The lower surface of going up the mould 11 of framed 1 lower surface is a column nick type array, and the upper surface of low mold frame 2 is a smooth flat.Upper and lower framed 1,2 material is a steel alloy.
The optional scope of specific refractory power of the column mirror grating that this technology is made is big, and the profile pattern of the glass column mirror grating of producing is good, precision is high, and good uniformity can be applied to the bore hole stereoscopic display device.
Claims (4)
