Abstract
The utility model relates to a tape-shaped glass temperature control device which is characterized in that heaters (2) are mounted on both sides of a glass tape (1) to be cooled, and at least two rows of heaters (2) are arranged along the moving direction of the glass tape (1), wherein each row is at least composed of two heaters (2). According to the utility model, the multiple heaters are arranged in multiple rows in the height direction, the height of a single row of heaters is lower than 260 mm, the quantity of heaters of each row is greater than or equal to one, and every two adjacent rows of heaters are arranged in such a manner that non-heating parts of the heaters are staggered. By using the device provided by the utility model, the cooling effect is ensured, the uniformity of the temperature field in the cooling process is ensured, and non-uniform heating caused by the distribution of the heaters is avoided.
Description
Technical field
The utility model relates to a kind of ribbon glass temperature-control device.
Background technology
As an important component part of flat-panel display device, remaining each several part all need be attached on the sheet glass, so this sheet glass is also referred to as base plate glass in the production of flat-panel display device.And flat-panel display device is along with the continuous increase of size, and is also more and more higher for the requirement of the planeness of sheet glass and internal stress in producing and using.In the process that flat-panel display device is produced, three important mass parameters that require for base plate glass are: surface smoothness, planeness and internal stress.
Overflow downdraw obtains larger application in producing planar substrates glass.In the production process of overflow downdraw, melten glass after treatment, drainage is to having in the overflow groove, through behind the overflow groove, cross the weir on overflow groove both sides after, along the flow downwards of the wedge shape of overflow groove, converge in the bottom, flow downward and stretch downwards, obtain planar substrates glass.Because in this process, the glass part of contacted surface of overflow groove is embedded in inside of glass plate, outside the outside surface deacration of sheet glass, does not contact any other material.Thus, adopt overflow downdraw to produce planar substrates glass owing to its inborn principle reason, can obtain the good planar substrates glass of outer surface quality.
In other two parameters, planeness has determined the quality of the flat-panel monitor that can produce, and internal stress has then determined the quality and the good article rate that cut in the size of flat-panel monitor and the flat-panel monitor production process.
From the pure theory angle, in the process of sheet glass cooling, the speed of cooling is slow as much as possible, and it is bad to guarantee that sheet glass is not subject to planeness and internal stress that the violent variation of temperature causes.But in overflow downdraw, the glass ribbon treatment process is arranged on the bottom of overflow device, and in practice because a variety of causes such as factory building height, the length of glass ribbon treatment process can not be accomplished very large.In this process, just very important for the setting of glass ribbon treatment temp curve.Glass ribbon treatment temp curve setting good when can significantly reduce building of production line cost, running cost, can guarantee that also the planar substrates glass of producing has good planeness and internal stress parameter.And temperature curve must need suitable heat sink to cooperate.Usually in glass industry, choose the vitreum annealing temperature point (viscosity points 1013dPas) of molten state, qualified temperature curve should guarantee in the cooling rate below the annealing temperature point less than the cooling rate more than the annealing temperature point aborning, simultaneously according to the size of the manufacturing capacity rational equipment of equipment and factory building and the dimensions of well heater.
The utility model content
The purpose of this utility model provides a kind of ribbon glass temperature-control device, has both had desirable cooling-down effect, can guarantee again temperature field in the temperature-fall period evenly.
A kind of ribbon glass temperature-control device, its special feature is: be separately installed with well heater in glass ribbon both sides to be lowered the temperature, and be provided with at least 2 row's well heaters along the glass ribbon travel direction, wherein each row is equipped with at least one well heater.
Gao Du＜=the 260mm of single well heater wherein.
Wherein well heater is comprised of fire end and non-fire end, and in arbitrary neighborhood two row's well heaters, the fire end of a well heater is the non-fire end of close another well heater all the time.
A plurality of well heaters arrange short transverse minute many rows in the utility model, and single well heater height is less than 260mm, and the quantity of every row's well heater is more than or equal to one, and adjacent two row's well heaters are at the non-hot spots of arranging the well heater that is staggered.After adopting the utility model device so that cooling-down effect is guaranteed, also guaranteed temperature field in the temperature-fall period evenly, the heating of having avoided the reason owing to heater profile to cause is uneven.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of ribbon glass temperature-control device, be separately installed with well heater 2 in glass ribbon to be lowered the temperature 1 both sides, and be provided with at least two row's well heaters 2 along glass ribbon 1 travel direction, wherein each row is comprised of at least two well heaters 2, and namely at least respectively there is a well heater 2 glass ribbon 1 both sides.
Wherein Gao Du＜=the 260mm of single well heater 2, and well heater 2 is comprised of fire end and non-fire end, and in arbitrary neighborhood two row's well heaters 2, the fire end of a well heater 2 is the non-fire end of close another well heater 2 all the time.
