INSTRUCTIONS: [Corresponding Cases Related to the Case] US Patent Application No. 61/264,017, filed on Nov. 24, 2009. TECHNICAL FIELD OF THE INVENTION The present invention generally relates to a method and apparatus for forming a glass sheet. More particularly, the invention relates to a method and apparatus for controlling the thickness of a glass sheet formed from molten glass. [Prior Art] A system for controlling the thickness of a glass sheet formed from molten glass is described in U.S. Patent No. 3,682,6G9 (S. M. D Gekeny). In the system of U.S. Patent No. 3,682,6G9, the molten glass flows downward on the opposite side of the forming member and joins at the wedge-shaped root of the forming member to form a glass sheet. The glass sheet passes between a pair of opposed housings having a front wall facing the glazing. The front wall is made of a material that has thermal conductivity, low ductility, and low emissivity (such as niobium carbide) 7 in Xingyou Ancient Putian. The fluid conduit is placed in the body. The nozzles of the fluid conduit are positioned in a spaced relationship on the back side of the front wall. ::: The fluid conduit has an associated flow meter that is provided with a control valve and a connection manifold. Each fluid channel & 1, the S delivers a cooling fluid or an additive fluid to the dorsal region of the adjacent front wall... ‘, 1 is deducted and δ, and the fluid delivered is a working emulsion. Heat exchange through pure shot occurs between the glass sheet and the front wall, 201125828 to control the thickness of the glass sheet. If the thickness of the glass sheet is recorded as a curve -), the area that does not span the width of the sheet is thicker than the desired thickness 1 through the area where the cooling glass is adjacent to the thicker area (i.e., the area where the cooling is thin) to correct the thickness recording curve. The fluid conduit corresponding to the adjacent zone is activated to cool the adjacent zone (i.e., the zone of (d)). The patent also creates a heated fluid that is passed to the back side of the front wall to be used as a conduit for the transfer of cooling fluid. In this example, the heated fluid is delivered through a fluid conduit corresponding to a thicker region. This will reduce the stickiness of the thicker areas and then thin the area. The heated fluid may be provided by an electrical winding associated with the fluid conduit. The above S is prepared and S, using the convection cooling centered wall (with / by, , , , conduction diffusion § hai effect) limits the resolution of the field of view of the device. Therefore, glass ribbon control during formation of higher resolution is required. The present invention satisfies this and other needs.

In operation, the device 201 is located at a portion 121 adjacent to the glass ▼ 113. The suction *', , and 201 are maintained at the specific glass portion 121. The lower temperature causes heat to be transferred from the glass ribbon portion (2) to the heat absorbing device 201 and absorbed into the suction rail.,, and the sill 201. The heating element 207 is used to shape the heat absorbing device 2〇1, 、, 刀Curve. How to mold The heat absorbing device, the force curve depends on the temperature curve of the glass ribbon portion 121 (or the 201125828 thickness curve). • Consider the imaginary example shown in Fig. 5, in which the glass ribbon portion 121 has the regions 5〇1, 503 , 505 and 506, these areas have temperature T5〇l, T5〇3, T505 and T506. T5〇1, T5〇3, T5〇5 and TS06 can vary in three dimensions, but for the sake of simplicity , Τ 5 (Η, τ 5 〇 3, Τ 505 and Τ 506 will be regarded as a single value. Now, suppose Τ 501 > Τ 503 > Τ 505 > Τ 506, that is, the temperature distribution in the glass ribbon portion 121 is non-uniform, and it is assumed that the problem is to make the glass ribbon The temperature distribution in the partial 丨2 1 is uniform. In this example, the thermal curve of the shapeable heat absorbing device 20 使得 causes the heat absorbing device 20 1 to absorb heat from the glass ribbon portion i 2 i in a different manner until T501=T503 = T505 = T506. Subsequently, it is assumed that the heat absorbing device 201 has regions 507, 509, 511 and 513 which individually have temperatures Τ 507, Τ 509, Τ 511 and Τ 513. Each of the heat absorbing device regions 507, 509, 5 11 and 513 One has more than one related plus Thermal element 207 and more than one associated temperature sensor 209. Further, assuming that the heat sink is sufficiently close to glass ribbon ι 21 that region 507 absorbs heat from glass ribbon region 501, heat sink region 509 absorbs from ribbon region 503. The heat, heat sink region 511 absorbs heat from the ribbon region 505, while the heat sink. region 513 absorbs heat from the ribbon region 506, as indicated by arrows 515, 517, 519, and 520. In order to achieve Τ501=Τ503=Τ5052Τ506 in the glass ribbon portion 121, Τ501, Τ503, Τ505, and Τ5 06 must be individually reduced by some quantities a, b, c, and d, where a>b>c>d. The output of the heating element 12 201125828 207 in the heat sink region 507, 509, 511, 513 can be adjusted such that T507, T509, T511 and T513 are individually from the glass ribbon regions 501, 503, 5〇5 and 5〇 at appropriate settings. 6 absorb the desired heat. In general, the following relationship is true: Τ 507 < Τ 5 〇 9 < Τ 511 < Τ 513. Adjusting the temperature distribution across the heat absorbing device 2〇1 so that the heat absorbing device 20 can absorb heat from the glass ribbon portion 121 in a different manner means “the thermal curve of the shaped heat absorbing device 2〇1”. Another way to consider the glass ribbon portion 12 is that the glass ribbon portion 121 has a hot zone and a cold zone. In order to average the thermal curve of the ribbon portion 121, more heat must be transferred from the hot zone than in the cold zone. Heat sink 201 can be used to control this heat transfer. By providing a relatively cold and hot region on the heat absorbing device 2, the heat absorbing device 2〇1 can absorb heat from the glass ribbon portion 121 in a different manner, so that the temperature distribution in the 12-inch portion of the ribbon portion becomes More evenly. Alternatively, it is considered that the glass ribbon portion ΐ2ι has a thick region and a thin region. & The thickness curve of the averaging glass ribbon portion 121 'more heat is transferred from the thin region' and less heat is transferred from the thick region. The heat absorbing device 201 can be redesigned to absorb heat 4' from the glass ribbon portion 121 in a different manner so that the thickness across the glass ribbon portion ΐ2ΐ becomes more uniform. The heat sink 201 is capable of absorbing heat from the glass ribbon portion 121 in a differential manner because it has a shaped heat profile. The thermodynamic curve of the glass ribbon can be actively shaped by controlling the heating element 2〇7. For example, some of the heating 70 207 can be controlled so that the areas of some of the heat absorbing devices 2 〇 1 are relatively hot, while some of the heating elements # 207 can be controlled 'to make certain heat absorbing devices 2 〇 1 Relatively cold. Pipeline 12 〇 (= 13 201125828 嗔 jet to the heat absorbing device 2 0 1 on the shape of the thermal curve. However, the shape resolution can not be as good as the degree of addition. 1) can also be used to transfer cooling fluid The shape-resolving heat-absorbing device 201, which is beneficial to the heat-absorbing device 20 1 and which is capable of transmitting the heat-receiving element by the cooling fluid jet alone, is a block of material having a high heat capacity and low thermal expansion. The surface of the heat absorbing device which is opposite to the glass ribbon portion (2) is continuous. This causes the heat sink 2〇1 to generate a heat dump for the glass ribbon portion (2). In some embodiments, the heat sink is a plate type (which may be flat as shown) or may have other shapes as will be further described below. In some embodiments, the material of the heat sink 201 is a ceramic material' such as, but not limited to, tantalum nitride and carbon carbide. Carbonized stone is an excellent heat spreader (spreade〇e gas cut has good high temperature strength, creep resisUnce and oxidation resistance. Compared with most ceramic materials including tantalum carbide, tantalum nitride It has good thermal shock resistance. The thermal conductivity of nitrogen cutting is less than half of the thermal conductivity of carbon cutting. Therefore, tantalum nitride can potentially provide a finer temperature curve than tantalum carbide. Other ceramic-based heat sink materials It can also be used for the heat absorbing device 20 1, for example, a material of a heat absorbing device based on an alloy or a nano material. Fig. 2, ', and the cross section of the heat device 2 〇 1. The heat sensor 207 is embedded in the heat absorbing as shown in the figure. In the device 201, the heating element 207 can be embedded in the heat sink 2 by, for example, forming a hole in the heat sink 2〇1 and inserting the heating element 207 into the hole. In an alternative embodiment, the heating element 207 It can be adjacent and very close to the surface of the heat sink 2〇1, and 14 201125828). This alternative embodiment can be easily replaced. In some embodiments the heating element 2 〇 7 is a resistive heating element made of a two-temperature material. High temperature materials can be inert materials

If the heating element is linearly heated by 70 pieces, the temperature profile across the heat sink 200 can be finely controlled by the small spacing between adjacent heating elements 207. The heating element 207 can be embedded in the heat sink 2?1 with or without a sheath depending on the material of the heat sink 201. For example, if the material of the heat sink 201 is an electrical insulator such as tantalum nitride, the heating element need not be sheathed. On the other hand, if the material of the heat absorbing device 2〇1 is an electrical conductor such as tantalum carbide, the heating element must be sheathed. Figure 3 shows an example of a sheathed heating element #2G7 comprising a high temperature conductor (or wire) 300 surrounded by a high temperature insulator 3G2 surrounded by a high temperature jacket 304. For example, the high temperature conductor 3 (9) may be made of platinum, a platinum alloy, a heavy metal alloy or the like. The high temperature insulator 3〇2 can be made of magnesium oxide, aluminum oxide, cerium oxide, cerium oxide or the like. The high temperature sheath 304 can be made of a platinum alloy or other high temperature metal or alloy. Other materials suitable for use as high temperature conductors, high temperature insulators and high temperature jackets can be used. The temperature sensor 209 is at least partially embedded in the heat sink 2〇1 of Fig. 2. The temperature sensor 2〇9 15 201125828 can be embedded in the suction 埶 by inserting a hole into the hole, for example, by inserting a temperature sensor 209 into the hole. n, 丄 · ', 01. In an alternative embodiment, the temperature sensor can be used on an endothermic surface. Temperature sensation (4) 209 can be, for example, a thermocouple or a thermistor (thermis called. - Generally, it is desirable that the sensibility measurement is made of a material that is inert in the oxidizing atmosphere and can withstand high temperatures. When the temperature sensor When 209 is a high temperature thermocouple, the thermocouple can be made of a starting, overturning alloy or a precious metal alloy. As in the example of heating element 207, between temperature sensor 209 (e.g., thermocouple) and heat sink 2〇 Electrical isolation may or may not be required depending on the material of the heat sink 2〇1. When electrical isolation is required (such as if the material of the heat sink 2〇 is carbonized stone), the heating element 2G7 is slightly covered. A similar solution can be used for the temperature sensor 209. The heating element 207 is designed to generate heat. For example, if the heating element 207 is a resistive heating element, electrical power can be transferred to the heating element... to induce the heating element 207 to generate heat. The heat generated by the heating element 2〇7 is dissipated to the heat sink 201. The fourth figure shows that the temperature sensor 2〇9 and the heating 7G#207 are exhausted to the controller. The controller has three functions: reading temperature, indicating power And lose Output power: The controller receives the output signal from the temperature sensing H 209. The output signal is used to generate a current thermodynamic curve for use by the heat absorbing device 2 〇 1. The current thermal curve for the heat absorbing device 201 and the desired heat absorbing device 2 The thermal curve of ι is compared. Subsequently, the (four) device 400 adjusts the output power to the heating element 2〇7. The signal is output through the control feedback loop, and the controller adjusts the current thermodynamic curve to match the desired thermal curve. The thermal curve of the heat absorbing device 2〇1 is determined by the temperature of the glass ribbon portion 121 (Fig. i), which is as explained above. The heat sink is indicated by the degree curve or the thickness curve as shown in Fig. 2 as a flat rectangle. In an alternative embodiment, the surface of the heat absorbing device 201 or the heat absorbing device 201 and the glass ribbon portion 121 (Fig. 1) may have a non-flat shape (e.g., a curved shape) to allow the heat absorbing device 2 The light-angle viewing angle factor between 〇1 and the glass ribbon portion (2) U 1 circle is maximized. The Xingchang shot angle factor is the ratio of the thermal energy leaving the surface of the glass ribbon ΐ2ι (the surface of the (4) to the surface of the heat sink i 2〇1, which is generally the heat sink 2〇1 and the glass ribbon part (2) The geometric calculation of (Fig. 1) is determined. The thickness of the heat sink 2〇1 depends on the conductivity of the material of the heat sink. In general, the heat of the material of the heat sink
導率愈低,則所需的吸熱裝置之厚度愈薄。例如H 化矽製成的吸熱裝置的厚度可為碳化矽所製成的吸熱裝 置的一半,並且傳遞與碳化矽相當的熱通量,其中q = ΚΔΤ/Χ,其中K是熱導率’ Δτ是溫度差而X是基材厚 度。例如’倘若寸(2 54㈣)厚的碳切傳遞特 定的q ’則欲傳遞相同的q需要G.5英州.27⑽)厚的氣 化矽。 回到第1圖,製做玻璃片的方法涉及形成玻璃帶113, 如前文所述。在形成玻璃帶113的同時,吸熱裝置201 定位在鄰接玻璃帶113的„部份121處,使得熱量透過 輻射從玻璃帶部份121傳送到吸熱裝置2G1。吸熱襄置 201基本上是做為玻璃帶部份121的吸熱體。玻填帶部 伤121瓜疋處於玻璃顯現黏性表現的溫度,同時吸熱 17 201125828 裝置2(H所處的溫度低於玻璃帶部份i2i溫度。玻璃帶 P伤121的位置-般是在接近楔形根部【冑(在楔形 根部1G7上方或下方),其中玻璃仍可能是在黏性的必須 衣士兄中。吸熱裝置201的寬度決定玻璃帶部份121的寬 度’因吸熱裝i 201是做為玻璃帶部份121的吸熱體。 一般而言,吸熱裝置201的寬度類似玻璃帶ιΐ3的寬度, 但在其他範例中可比玻璃帶113的寬度更短或更長Γ 吸熱裝i 201卩有差異的方式„及收來自玻璃帶部份 121的熱里。s玄差異式吸收是由吸熱裝置的熱力曲 線所決定,訪由加熱元件207以及視情況任選地由來 自管路120的冷卻流體喷射流所控制,其如前文所解 釋。在某些實施例中,吸熱裝置2〇1的熱力曲線是使得 熱3:從玻璃帶121的不同區域以一量值傳送到吸熱裝置 20卜該量值反比於在該些區域中的玻璃厚度。在某些實 施例中,吸熱裝置2〇 1的熱力曲線使得從玻璃帶部份^ 2 ^ 的較薄區域傳送至吸熱裝置2〇1的熱量多於從玻璃帶部 伤121的較厚區域傳送至吸熱裝置2〇1的熱量。最終結 果可為吸熱裝置201有以差異的方式從玻璃帶部份121 吸收熱量,使得玻璃帶部份121的溫度曲線或厚度曲線 更加均勻。 當玻璃帶113移動遠離形成構件1〇1的楔形根部1〇7 時,具有修改過的溫度曲線或厚度曲線的玻璃帶部份^ 2 ^ 會與玻璃帶113移動。新的玻璃帶部份將會取代舊的玻 璃帶部份121。吸熱裝置可從新的玻璃帶部份以有差異The lower the conductivity, the thinner the thickness of the desired heat sink. For example, a heat sink made of H bismuth can be half the thickness of a heat sink made of tantalum carbide and deliver a heat flux equivalent to that of tantalum carbide, where q = ΚΔΤ/Χ, where K is the thermal conductivity 'Δτ It is the temperature difference and X is the thickness of the substrate. For example, if the inch (2 54 (four)) thick carbon cut passes a specific q ′, then the same q is required to require G.5 Yingzhou.27(10)) thick gasification enthalpy. Returning to Figure 1, the method of making a glass sheet involves forming a glass ribbon 113 as previously described. While forming the glass ribbon 113, the heat absorbing device 201 is positioned adjacent to the portion 121 of the glass ribbon 113 such that heat is transmitted from the glass ribbon portion 121 to the heat absorbing device 2G1 through the radiation. The heat absorbing device 201 is basically used as a glass. The endothermic body with part 121. The glass-filled part of the wound is 121 in the temperature at which the glass shows viscous performance, and the endothermic heat is 17 201125828 device 2 (H is at a temperature lower than the temperature of the glass ribbon portion i2i. The position of 121 is generally near the wedge root [胄 (above or below the wedge root 1G7), where the glass may still be in the viscous must-have. The width of the heat sink 201 determines the width of the glass strip portion 121. 'Because the heat absorbing i 201 is a heat absorbing body as the glass ribbon portion 121. In general, the heat absorbing device 201 has a width similar to that of the glass ribbon ι 3, but in other examples may be shorter or longer than the width of the glass ribbon 113.吸 The heat sink i 201 has a different way „ and receives the heat from the glass ribbon part 121. The sin differential absorption is determined by the thermal curve of the heat sink, accessing the heating element 207 and optionally optionally The cooling fluid jet from line 120 is controlled as previously explained. In some embodiments, the thermal profile of heat sink 2〇1 is such that heat 3: is transmitted from a different region of glass ribbon 121 by a magnitude The amount to the endothermic device 20 is inversely proportional to the thickness of the glass in the regions. In some embodiments, the thermal profile of the heat sink 2〇1 is such that it is transferred from the thinner region of the glass ribbon portion to the endothermic portion The heat of the device 2〇1 is more than the heat transferred from the thicker region of the glass ribbon portion 121 to the heat absorbing device 2〇1. The end result is that the heat absorbing device 201 absorbs heat from the glass ribbon portion 121 in a different manner, so that The temperature profile or thickness curve of the glass ribbon portion 121 is more uniform. When the glass ribbon 113 moves away from the wedge-shaped root portion 1〇7 of the forming member 1〇1, the glass ribbon portion having the modified temperature profile or thickness curve ^ 2 ^ Will move with the glass ribbon 113. The new glass ribbon portion will replace the old glass ribbon portion 121. The heat sink can be different from the new glass ribbon portion.

Or, with a shaped heat koji 2G1 can be with the pipeline The cooling fluid jets of 120 are used together to control the thickness of the glass ribbon portion 121. As previously explained, the partial body jets may have the effect of the shape of the thermal curve of the endothermic cracking 2 ( (although such effects It can be comprehensive), while relying on the addition of the second _ 207 to finely control the shape of the thermodynamic curve. The pipe 1 can be similar to the fluid conduit described in U.S. Patent No. 3'682,6,9, and the flow rate is permeable.

The heat absorption, set 2〇1, may be used instead of the centering described in U.S. Patent No. 3,682,609. The thermal curve of the shaped heat absorbing device 201 to achieve the thickness control of the glass 12 15 1 requires the knowledge of the temperature I knife cloth or the thickness curve of some of the glass ribbon portions 12 1 . This may involve actively measuring the glass ribbon portion 1 or Based on the history of 201125828 obtained using a specific process setting and parameter set: The thermal device assembly 201 can be a single-unit having a width sufficient to cover the width of the glass portion 121, wherein the glass ribbon portion is 121% wide and glass The width W of the belt (1) is the same or different. Alternatively, the heat absorption may have a modular structure in which a plurality of modules can be arranged one after another to form a heat absorbing package of a desired width. Alternatively, the plurality of modules may be individually Arranged in a portion of the glass ribbon 113 that requires thickness control. In some embodiments, it is also possible to control the temperature of the heat sink such that at least a portion of the surface of the heat sink facing the glass ribbon has a higher heat absorption The temperature of the corresponding zone of the glass ribbon in the thermal field of view of the device. In these embodiments, heat is transferred from the heat sink to the glass ribbon, effectively increasing the temperature of the exposed area and the viscosity of the glass, thereby reducing the thickness of the glass ribbon. The invention has been described in terms of a limited number of embodiments, and it will be understood by those skilled in the art of this disclosure that the invention can be devised without departing from the scope of the invention disclosed herein.
