Description
Technical field
The present invention relates to a kind of cutting method, relate in particular to a kind of cutting method that improves the spectral filter of substrate utilization ratio.
Background technology
Color block filter is that the color separation filter by red, green, blue, one chip fan-shaped ring such as white forms through glue bond.Spectral filter is one of element important in the colour wheel device, and it is after cutting into a plurality of one chip fan-shaped ring substrates by the transparency carrier that glass material or quartzy material are made, and glues together to form after plated film is made again.
As Fig. 1 and shown in Figure 2, the cutting method of existing a kind of spectral filter, utilize cutting machine (figure do not show) that quadrate substrate 10 is cut into several circular substrates 12 earlier, utilize the glass clipper this circular substrate 12 to be cut into the color block filter substrate 16 of a plurality of required one chip fan-shaped rings according to the predetermined angular size again.
Yet, adopting the cutting method of above-mentioned spectral filter, described quadrate substrate 10 can produce clout 14 after cutting into several circular substrates 12 simultaneously.If clout 14 can not cut into a complete circle, during the cutting machine cutting, can cut to the edge 15 of substrate 10, because there is certain thickness at the edge 15 of substrate 10, so, cutting machine can not can produce the limit problem that collapses in the equal-height position cutting of substrate 10 during incising circular substrate 12.Therefore, can only slattern this clout 14, so just reduce the utilization ratio of substrate 10.
Summary of the invention
In view of this, be necessary to provide a kind of cutting method that improves the spectral filter of substrate utilization ratio.
A kind of cutting method of spectral filter, it may further comprise the steps:
One eyeglass substrate to be cut is provided, and this eyeglass substrate to be cut comprises a plurality of sides, at least one pad is positioned over respectively by at least one side of eyeglass substrate to be cut;
Eyeglass substrate cut to be cut is become a plurality of first circular substrates, and described eyeglass substrate to be cut remains a plurality of clouts district;
The clout district and the pad of eyeglass substrate to be cut are cut into a plurality of second circular substrates;
First circular substrate is cut into circular substrate;
Described circular substrate cut is become a plurality of fan-shaped ring substrates;
Remove the pad on second circular substrate, second circular substrate is cut into a plurality of fan-shaped ring substrates.
With respect to prior art, described second circular substrate is formed by the clout district and the pad cutting of eyeglass substrate to be cut, and therefore, second circular substrate comprises a part of pad.Because spectral filter is to be formed through the adjacency gummed behind the plated film respectively by a plurality of fan-shaped ring substrates again, after second circular substrate is removed pad, the clout district of described eyeglass substrate to be cut also can cut into a plurality of fan-shaped ring substrates, these a plurality of fan-shaped ring substrates are through forming spectral filter behind gummed, so, improved the utilization ratio of eyeglass substrate to be cut.

Embodiment
See also Fig. 3 to Fig. 7, be the cutting method of spectral filter of the present invention, it may further comprise the steps:
Step S301 provides an eyeglass substrate 20 to be cut, and this eyeglass substrate 20 to be cut comprises a plurality of sides 21, will to be positioned at least one side 21 of eyeglass substrate 20 to be cut other with the contour pad 30 of eyeglass substrate to be cut 20;
Described pad 30 is in the same plane with described eyeglass substrate 20 to be cut, and preferably, described pad 30 and described eyeglass substrate 20 to be cut are that the thickness of the thickness of identical material and this pad 30 and this eyeglass substrate 20 to be cut is identical.In the present embodiment, described at least one pad 30 is two pads 30, and these two pads 30 do not have the gap respectively and are positioned over 20 2 opposed side edges of described eyeglass substrate to be cut, 21 sides.In the practical application, described at least one pad 30 can be different materials with described eyeglass substrate to be cut 20 also, this at least one pad 30 also can be a pad 30, this pad 30 is positioned over any side 21 of described eyeglass substrate 20 to be cut, it is other that described pad 30 also can be positioned over each side 21 of described eyeglass substrate 20 to be cut respectively, is not limited to present embodiment.
Step S302 cuts into a plurality of first circular substrates 24 with eyeglass substrate 20 to be cut, a plurality of clouts of described eyeglass substrate to be cut 20 residues district 23;
In the present embodiment, utilize first circular substrate 24 of cutting machine (figure does not show) with a plurality of predetermined radiis of eyeglass substrate to be cut 20 cuttings.
Step S303 cuts into a plurality of second circular substrates 25 with the clout district 23 and the pad 30 of eyeglass substrate 20 to be cut;
In the present embodiment, described pad 30 and described eyeglass substrate 20 to be cut at grade, and the thickness of the two is identical.Therefore, cutting machine on the clout district 23 of eyeglass substrate 20 to be cut and pad 30 during cutting second circular substrate 25 under sustained height, can not produce and collapse the limit phenomenon.The radius of described second circular substrate 25 is identical with the radius of described first circular substrate 24.
Step S304 cuts into circular substrate 241 with first circular substrate 24;
Center of circle o with first circular substrate 24 is the disk 246 that the center of circle cuts away a predetermined radii earlier, obtains a plurality of circular substrates 241.Described disk 246 is generally waste material.
Step S305 cuts into fan-shaped ring substrate 243 with described circular substrate 241;
Angle between described two adjacent pre-calibration paths 244 equates, for example, when needs cut into the same five of angle when fan-shaped, angle between described adjacent two pre-calibration paths 244 is 72 degree, when needs cut into the same six of angle when fan-shaped, the angle between described adjacent two pre-calibration paths 244 is 60 degree.Certainly also can cut described pre-calibration path 244 according to the arbitrarily angled size of required segmental.In the present embodiment, the angle between described two adjacent pre-calibration paths 244 is 72 degree.
Step S306 removes the pad 30 on second circular substrate 25, and second circular substrate 25 is cut into a plurality of fan-shaped ring substrates 243.
The method of 24 one-tenth a plurality of fan-shaped ring substrates 243 of 25 one-tenth a plurality of fan-shaped ring substrates 243 of described cutting second circular substrate and described cutting first circular substrate is identical, repeats no more here.
Described second circular substrate 25 is formed with pad 30 cuttings by the clout district 23 of eyeglass substrate 20 to be cut, therefore, second circular substrate 25 comprises a part of pad 30, because spectral filter is to be formed through the adjacency gummed behind the plated film respectively by a plurality of fan-shaped ring substrates 243 again, after second circular substrate 25 is removed pad 30, the clout district 23 of described eyeglass substrate 20 to be cut also can cut into a plurality of fan-shaped ring substrates 243, these a plurality of fan-shaped ring substrates 243 are through forming spectral filter behind gummed, so, improved the utilization ratio of eyeglass substrate 20 to be cut.
Those skilled in the art will be appreciated that; above embodiment only is to be used for illustrating the present invention; and be not to be used as limitation of the invention; as long as within connotation scope of the present invention, appropriate change and variation that above embodiment is done all drop within the scope of protection of present invention.
