Description

V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a flat plate breaking formation stronger than a flat plate breaking manufacturing by an overflow process. Apparatus' and especially related to [prior art] The present invention relates to a kind of flat glass which is currently used for the identification of display devices ... for the manufacture of flat glass for tft / lcd m devices, in which TFT / LCD displays F g It is expected to be used in televisions in the future. For the semiconducting quality, the flat glass of the device No. 6 9 6 is successful. This patent teaches that the glass breaks the glass and overflows and needs to be ground. The US patent is used. However, the device must be filled with non-applied semiconductor materials. U.S. Patent No. 3,318, the content of which is incorporated herein by reference.) When it is formed, it does not require post-processing to have the highest glass mouth. "This is called an overflow manufacturing method. ^ Key flow of overflow method In and out of glass forming equipment, untouched, raw, and glass-forming outer surfaces. Soil-damaged and / or polished by other methods, so does not have a fine smooth surface. No. 3, 338, 696 The content of the teaching is still limited by the industry. The main disadvantage of the current overflow method is that the manufacturing speed of the existing device is limited. According to simple mathematical operations, the glass flow is accurately manufactured and broken.螭 The tangent of viscosity and oblique angle must be fixed so that the existing device can produce glass with uniform thickness. In application, the tilt and angle have practical restrictions, and because of the non-linear structure, it is impossible to have a simple Mathematical assumptions, thus limiting the range of manufacturing rates. Even if the thickness of the flat glass is curved or uneven, there is no

V. Description of the invention (2) The material of the device is subject to the uniform thickness of the plate, and is uniform. Righteousness must operate for several years. It takes a month to regenerate and operate, so the knowledge used may need to be adjusted. Stop method adjustment. During manufacturing, the forming device is deformed due to rot # and thermal creep. This uneven plate thickness cannot be adjusted and adjusted. It is possible to use the 'broken glass formation method' to stop the production line for a month, and then start it again. Because the entire system is at extreme temperatures, the material is under fixed stress, and the material is often abrasive and production can cause unnecessary adjustments or repairs. " Overflow method "device can produce excellent glass under stable operation conditions, but the recovery rate from transition conditions is very slow. $ ^ This is because the glass flowing through the forming device The flow is quite uneven. The time flow of the glass flowing into the glass, forming the flat glass = the machine glass and the breaking glass forming the far end of the flat glass is not close. When flowing from one end to the other, the far end of the flat glass The 10% glass-based glass is at least slow—orders. The increase in time difference is improper.] The cross section of the flow channel caused by the flow channel has a region where the glass velocity bites. Another disadvantage of the 3'338,696 patent is that its material is larger and larger as the manufacturing speed increases. The device usually needs to make part 7 made of or covered with refractory metal. ': That is, platinum) to make it durable. However, increasing the size of the system will increase the cost of manufacturing equipment. The deflector overflow process device will increase as the manufacturing speed increases, because the material flow Guide the glass along the overflow < the flow of the plate depends on the flow of gravity. With the increase of glass, glass, the flow tank must be larger, the slope of the deflector is steeper or the glass:

5. Description of the invention (3) Low enough to accommodate the increased glass fluid. As a result, there is a limited range of manufacturing speeds that are already tolerated. Another disadvantage of this device is that it can only be made in fixed width glass. [Summary of the Invention] The present invention includes design features that can be used individually or in combination to make the glass sentence flow through the device and adjust the thickness of the flat glass. The distal end of the trough and the viscosity range of the tilting device are used together to produce more satisfactory changes to the glass screed. The thickness of the broken glass is wedge-shaped, which provides a larger flow rate of the glass fluid and can lift the flat glass. Similarly, the area of the stream is minimized. The hole set on the top of the flow tank is narrow at the feed end, but the static pressure difference caused by the end. Holes with extra holes on the sides or sides can effectively make the irregular thickness of the shaped part can be adjusted by the deflector or the hole of the outer glass, and the small device can be set as a plate glass overflow device. For flow, to increase the glass flow rate and the flow device, the device can be tilted to adjust the glass viscosity (temperature). The device can be non-linear. The cross-section formed by adjusting the time-dependent flow into the tube can make the static flow forming device can include force. Glass access device. The width of the holes to tolerate slope flow to the forming device can be greater at the bottom. Extra glass increases the amount of slope glass. The formed sloping sloping glass in the hopper is heated to selectively heat the flowing down device to make the product together faster and more evenly. Overflow and change. In addition, the shape range. For more uniform holes and uneven grooves, use pressure to make holes at the far end to make the plate thick.

The purpose of this project is to manufacture a flat screen with a display device. • The glass must have a very high surface quality, and the flat glass produced by the overflow process must also have a high-quality surface. The overflow process is defined as: 1) moving molten glass into the flow tank; 2) meeting the broken glass on each side of the overflow, so that the outer surface of the flat glass is formed by / on the surface of the glass forming device that is not in contact (Post-fixing step). This untouched, original glass '' is formed into an extremely uniform and clean outer surface of flat glass. Any method or device modification must provide such a high-quality glass surface. The fluid mechanics system in all the specific embodiments of the present invention is: the outer surface of the flat slope soil is formed by the uniformly mixed original glass, which comes from the center of the glass flow flowing into the forming device, and thus does not contact the refractory material or refractory Metal surface. This results in the highest possible surface quality. The original glass (pristine) surface is a basic requirement for manufacturing LCD / TFT semiconductor display devices.

564240 V. Description of the invention (8) The bottom and sides of the groove (4) have a certain shape so that the glass is more evenly distributed on the deflector (5) on each side. The glass (2) mainly flows through the upper surface of the deflector (5) on each side, flows down to the mother side of the wedge-shaped part forming the device (1), and then meets at the bottom of the wedge to form the fused glass (2) board. Then, the fused glass (2) is cooled to form a solid flat glass with almost uniform thickness. A small part of the glass (2) flows out of the other end through the overflow device (1 0) by forming a flow trough (4). The overflow device (10) integrated at the far end of the stream 9 trough (4) is tilted f with the device (i) to change the double glass flow rate and viscosity to adjust the thickness curve of the flat glass. The flat glass forming device is designed to be operated at a fixed temperature in the area where the flow trough (4) and the deflector (5) are formed. From: :::: ^ ㈤㈤ ... The thickness of a linear plate resistant to ⑴ is called a wedge. It should be a function of the shape of the L section groove (4) and the shape of the deflector (5) on the flow material.

V. Description of the invention (9) Correct both wedge and curvature. This can result in longer production activities for existing forming devices, thereby reducing manufacturing time and saving costs. ^ Green Correction Grave The conventional technology requires the flow channel (4) to be rectangular, and other components are not considered except for the straight deflector. Figures 3a to 3d show a specific embodiment, which is the same as the specific embodiments shown in Figures 2a to 2d, except that the two deflectors and the bottom of the flow channel (4) have a certain embodiment. This shape allows the fluid flowing through the entire length of the deflector (5) to flow uniformly. Figures 4a to M are the same as the specific embodiments shown in Figures 2a to 2d, except that the flow channel (4) has a flat bottom and only the deflector (5). Shaped 'makes the fluid flow uniform across the entire length of the baffle. The bottom of the heading trough (4) is shown horizontally, but it can also be inclined. The precise shapes of the flow trough (4) and the deflector (5) can be calculated using any number of computational fluid power package software, such as CFD2000TM, FluentTM, Flow 3DTM, and solving the Navier Stokes equation. The criterion for a satisfactory design is a nearly uniform flow distribution in the longitudinal direction of the pointed portion (2 5) of the glass follower (1) at the desired flow rate. In order to understand the equation, a spatial frame is constructed to reproduce the desired internal geometry of the inflow pipe (3), the recessed part of the flow channel (4) and the shape of the upper surface of the deflector (5). The fluid properties, together with the boundary conditions, represent the walls, free surfaces, and desired process glass flow rates. The trial solution is executed and the component size and shape are corrected 'until the solution produces a fluid distribution that meets the design criteria at the pointed portion (25) of the device (1).

The section of the inflow tube (3) is determined by the requirements of the application, including considerations such as fluid adjustment, heat loss, and ease of manufacture. Non-rectangular flow In the same purpose, the section of the trough wants to shorten the time gap between the near end and the far end of the flat glass. This is mainly achieved by changing the rectangular section of the trough (4) to reduce the area of very slow glass flow. The glass π plate forming device 11 of the patent No. 3,3 3,8,6 9 6 requires a rectangular plate to form the cross section of the flow channel, which itself generates an unnecessary slow flow area. However, the present invention can allow the flow tube (4 ) The cross section has a certain shape to minimize the static flow area. Figures 7a, 7b, and 7c show the cross section of the head of the forming device. The shape of the cross section of the head (4) is also determined by The needs of the application, the main factor is the fluid distribution from the flow channel (4) to the deflector (5). Other considerations, such as the main determinant factor, is through the flow channel (4)-to the deflector (5) ) Fluid distribution.

The V item, the neck, and the ten-kilometer mouth can reduce the manufacturing rate for the durability of the device, which can increase the manufacturing rate ^ The use of the equipment will cause the flow rate of the glass to be mainly controlled by the feed pressure of the glass, the glass structure, and the mouth structure, and the second is controlled by gravity. _ $ Coupling / claw limbs within the target range and glass viscosity range is conducive to process development, and can use the same device to manufacture almost different products. In all the specific embodiments described below, 'from the inflow tube into the device The glass has a static pressure of 0.025-5. 0 bar. The specifications of low or high pressure are related to this defined pressure range. Figures 8a to 8c show the specific implementation of the overflow glass forming device (1) For example, the overflow glass forming device (丨) is typically a system that operates under Aida's low feed pressure. The glass (2) enters from the inflow pipe (3)) to the farm (1). The flow trough (4) faces The distal end is tilted to allow flow to the device: end, glass residence time Short. The hole (20) is located on the device, m2m ^ plane and extends horizontally from near the feed end to the near end.

Female surface ship, tender-V. Description of the invention (13) The inlet end with the higher pressure is very narrow, but the static pressure difference at the moment. The effect of static pressure difference caused by the less exaggerated in the hole embodiment is smaller. The fine fluid distribution of the dagger hole (20) is very heavy, or in order to improve the hole ((aluminum oxide) reinforcement, it is made from a molten platinum spray method material plate. It is formed. It can cover the previous layer and can be sprayed directly when The surface tension shadow body moves toward the forming device (1. In the free space below, the holes (20) are adjusted to cope with the surface opening position of the surface to form a device (for the pointed part (2 5)) in the shape of each hole (20) The cloth (wedge) at the bottom of the wedge is mainly a system that operates under the pressure of the material. The hole (20) is slightly wider at the far end of the feed to allow the glass (2) to flow to this / same (20) The pointed structure is specific at this higher pressure because the glass flowing through the sloping stream in the flow channel (4) flows through the hole (20) to the side of the device (1). The mechanical structure is uniform for the required during manufacturing. Yes. The hole (20) can be made of refractory material, and the durability of 2) can be made of refractory metal (platinum) if necessary.

Any wedge shape change can be achieved by tilting the thickness of the intermediary plate, which will allow more slope glass (2) to flow to: the thickness of the lower distal end increases. The result is that the sloping flat plate is broken -4 to Figure 10c is the reflow material of the overflow soil breaking formation device (!), &Quot; Λ 'glass enters the formation device from the inflow pipe (3) (".

The hole (20) is wider at the end of the inlet to compensate for the difference in static when the glass flows to that end.

Note the change in width It is smaller than the specific embodiments shown in Figures 8a «to 8c and Figures 10a to 10c.

10356twf.ptd Page 19 V. Description of the invention (15) The static pressure difference of the glass (2) entering the distal end is compensated by the method of increasing the static pressure of the distal end by gravity. The hole (20) also has a more complex shape due to the interaction of fluid and gravity. The holes (20) are designed to produce the desired uniform flow from the head (4) to the side of the device (1). The advantage of this specific embodiment is that the holes (20) are cut so that their exposed surfaces face the flow channel (4) or outside the device. This general design will provide a geometric structure ‘by which’ the surface of the head (4) and the holes (20) may be coated with refractory metal by spray coating. However, this embodiment has a wider range of operating fluid conditions due to the effect of gravity, as in the device described in Patent No. 3,338,696. In some applications, such as this embodiment, the practice of tilting and having a certain shape of the hole (20) beyond the horizontal plane can produce very good fluid characteristics and / or simplify the structure. Normal and ancient, this only pays the price of limiting the operating range of the existing device (1).

The flow control bolt (3 0) (the shape of the k k is from two) is designed to adjust the flow production in the flow hopper (4), and the static pressure of the entire length to the hole (20) shown in Figures 13a and 13c is not change. \ Make the feed end along the text. The hole (20) runs along it

The individual glass was changed to use} Zheng and Yuan} to compensate for production 564240 Description of the invention (16)-The lengths are narrow and the widths are almost the same. Because the static pressure of the glass flowing through the hole (20) changes the same throughout the length of the flow, the uniform-width hole (20) flow channel (4) to the side of the device produces the desired uniform flow. The flow control pin (30) can move vertically in the flow channel (4), change the fluid distribution, and cause a concave or convex shape of the plate thickness. This can compensate for changes in the plate thickness distribution caused when the performance of the device deteriorates. Although Figures 1a to 13c show one of the shapes of the flow control plug (30), the flow control plug (30) can also have other shapes, so that the plug (30) is beneficial to the operating system. Theoretical and empirical operation improvements allow rapid adjustment of system changes by making certain devices have several readily available flows. For example: = 3 3; calibrate the parts that are about to wear, you can depict what may happen ;; make new bolts (30) to prepare for occasional needs. Shapes of other flow control pins (30) for special purposes such as pyramids, cones or prisms. Unique irregular flow control pin with eccentric circular shaft (30 can be located in the center of the flow tank (4) or partially buried at the bottom of the flow tank (4). The pin (30) can be rotated around its axis to change The fluid distribution and thus make up the thickness variation of the plate. It can also be tilted and / or moved horizontally or vertically to produce the desired plate thickness distribution. Multiple holes-bottom holes 4 The method of overflow is limited by the plate thickness that can be generated by the system It is rarely able to improve the thickness of the plate during the operation of the manufacturing method. A specific embodiment of the present invention provides a forming device with a plurality of holes.

564240 V. Description of the invention (17) makes the thickness of the plate change greatly. The forming device suitably includes two independent sides, where the sides may, but need not, be mirror images of each other. The outer shape is basically an elongated wedge with the tip facing down. The glass enters one end of the flow trough formed by the pressure of the two forming device sides and flows out of the top and bottom of the hole formed by the two plates. Effectively, the bottom hole increases the amount of glass in the middle of the plate glass formed. Figures 14a to 14c are a top view, a side view, and a feeding area of a specific embodiment with a horizontal top hole (20), a horizontal bottom hole (3 5), and a flow channel (4) having a certain shape. view. The glass (2) enters the device from the inflow pipe (3). The flow trough (4) is formed by two independently installed side edges (36) and an end cover (34). It gradually sharpens to the far end, minimizing the residence time of the glass flowing to that end of the device (1). The independent sides (36) are shown in Figures 15a-15c. The hole (20) above the upper surface of the device (1) extends horizontally from near the feed end to near the far end. The distal end is wide to compensate for the static pressure difference caused by the glass fluid in the flow channel (4). The holes (3 5) on the bottom of the distal end are also wide, and their shape causes a specific fluid distribution along the entire length of the hole. Most of the glass forming the flat glass flows out of the bottom hole (3 5). The glass flowing out of the top hole (20) flows down along the inclined side of the wedge, and merges with the bottom hole (3 5) at the bottom (the pointed portion (2 5)) to form a smooth plate of molten glass.
