Description
Technical field
The utility model relates to a kind of structure of glass stack roll surface.
Background technology
The grain roller decorative pattern used in current photovoltaic glass production process is not of uniform size, and light penetration is unstable, easily produces the problem of stress concentration in the process of the not high and roll extrusion of yield rate.
Though more existing glass stacks have decorative pattern but be all that vertical bar type decorative pattern is if Authorization Notice No. CN203451350U (a kind of vertical bar glass roll) or heptahedron decorative pattern are as Authorization Notice No. CN202898215U (a kind of woven design flower pattern roller).With water chestnut limit (i.e. non-arc chord angle) on the inner-wall surface of the pit that the decorative pattern of these shapes extrudes on glass basal plane, the refraction of light can be caused, add the diffusion of light, decrease the transmitance of light, be unfavorable for the utilization of luminous energy.
In addition when adopting above-mentioned two kinds of decorative patterns, the pulling force in calender line between roll surface and bath of glass is large, is unfavorable for deviating from of glass.
Utility model content
The utility model is intended to solve the problem, and provide a kind of structure of glass stack roll surface, that reduce the diffusion of light, be beneficial to the utilization of luminous energy, the pulling force in calender line between roll surface and bath of glass is little, and its technical scheme adopted is as follows:
A kind of surface structure of novel glass stack, it is characterized in that: its roll surface is evenly equipped with the elliptical cylinder-shape decorative pattern that several shapes, size are all identical, the projection that described decorative pattern is cross section ovalize, vertical section is rectangle, the major axis of described projection and the axis being parallel of glass stack, between the projection that left and right is adjacent, major axis connects, and between neighbouring projection, minor axis connects.
On technique scheme basis, the distance of summit to its bottom surface of described projection is 80 ~ 300 microns.
On technique scheme basis, on described roll surface, palmar density is 20 orders/inch to 50 order/inch (referring to the quantity of single decorative pattern in 1 inchage).
Optionally, when on described roll surface, palmar density is 20 orders/inch, long 1.275 millimeters of protruding major axis, long 1.06 millimeters of minor axis.
Optionally, when on described roll surface, palmar density is 25 orders/inch, long 1.02 millimeters of protruding major axis, long 0.85 millimeter of minor axis.
Optionally, when on described roll surface, palmar density is 40 orders/inch, long 0.64 millimeter of protruding major axis, long 0.53 millimeter of minor axis.
The utility model tool has the following advantages:
One, at the glass calendering initial stage, make glass basal plane form elliptical cylinder-shape pit, reduce glass tension and the pulling force between roll surface and bath of glass in calender line, the glass decorative pattern produced is full, not yielding, improves glass finished-product rate.
Two, can extend as cylindrical pit in the process that elliptical cylinder-shape pit glass basal plane formed is pulled at glass subsequently, glass basal plane is formed several concavees lens, sunlight converges to polysilicon film and carries out transform light energy after superrefraction, due to the inner-wall surface of pit not having water chestnut limit, decrease the diffusion of light, improve the transmitance of light.
Accompanying drawing explanation
Fig. 1: the local structure schematic diagram of glass stack roll body outwardly deploying described in the utility model;
Fig. 2: convex cross section described in the utility model;
Fig. 3: protruding vertical section described in the utility model;
Nomenclature:
1. protruding, 2. roll surface.
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
Here it should be noted that, the upper and lower, left and right of the noun of locality described in literary composition are all define for benchmark with the view shown in Fig. 1, should be appreciated that the protection domain that the use of the described noun of locality should not limit the application and asks.
Embodiment 1
As shown in Figure 1 to Figure 3, the surface structure of a kind of novel glass stack of the present embodiment, it is characterized in that: its roll surface is evenly equipped with the elliptical cylinder-shape decorative pattern unit that several shapes, size are all identical, the projection that described decorative pattern is cross section ovalize, vertical section is rectangle, the major axis of described projection and the axis being parallel of glass stack, between the projection that left and right is adjacent, major axis connects, and between neighbouring projection, minor axis connects.The distance of summit to its bottom surface of described projection is 80 microns.On described roll surface, palmar density is 20 orders/inch, long 1.275 millimeters of protruding major axis, long 1.06 millimeters of minor axis.
Embodiment 2
As shown in Figure 1 to Figure 3, a kind of surface structure of novel glass stack, it is characterized in that: its roll surface is evenly equipped with the elliptical cylinder-shape decorative pattern that several shapes, size are all identical, the projection that described decorative pattern is cross section ovalize, vertical section is rectangle, the major axis of described projection and the axis being parallel of glass stack, between the projection that left and right is adjacent, major axis connects, and between neighbouring projection, minor axis connects.The distance of summit to its bottom surface of described projection is 300 microns.Optionally, on described roll surface, palmar density is 40 orders/inch, long 0.64 millimeter of protruding major axis, long 0.53 millimeter of minor axis.
During calendering, glass stack first extrudes elliptical cylinder-shape pit on bath of glass, because pulling force (pulling the power of glass) is along the short-axis direction of pit, because semi-solid state glass has ductility, the minor axis of pit can be stretched the cylindrical pit of final pit (minor axis is stretched to equal with long axis length), by the long axis length of above-mentioned also known projection and minor axis length setting not arbitrarily, need a large amount of experiments just can obtain, and the decorative pattern of elliptical cylinder-shape is more excellent than columniform decorative pattern, the inner-wall surface of the cylindrical pit formed do not have water chestnut limit, decrease the diffusion of light, improve the transmitance of light, glass basal plane is formed several concavees lens, sunlight converges to polysilicon film and carries out transform light energy after superrefraction, efficiency of conversion is high.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
