Definitions
- the present invention relates to a method for manufacturing a glass film and a manufacturing apparatus therefor, and more particularly to a technique for manufacturing a long glass film that enables the glass film to be rolled up.
- FPDs flat panel displays
- LCDs liquid crystal displays
- PDPs plasma displays
- FEDs field emission displays
- OLEDs organic EL displays
- organic EL for example, is not limited to blinking the three primary colors with a TFT like a display, but is also used as a flat light source such as an LCD backlight or a light source for indoor lighting by emitting only a single color (for example, white). It's getting on.
- the light emitting surface can be freely deformed as long as the glass substrate can be provided with flexibility. For this reason, also for glass substrates used in this type of lighting device, significant thinning (making glass films) has been promoted from the viewpoint of ensuring sufficient flexibility.
- a glass film ribbon having a plate thickness of 30 ⁇ m to 2000 ⁇ m is formed by a down draw method, particularly a slot down draw method.
- the glass film ribbon pulled out vertically is bent (curved) in the horizontal direction, then both ends of the glass film ribbon are cut off using a laser, and then the glass film ribbon is cut into a predetermined length.
- a technique for cutting out a glass substrate having a predetermined size has been proposed. Further, it is described that a glass film ribbon having a plate thickness of 30 ⁇ m to 400 ⁇ m can be wound up (by a predetermined roller or the like) without cutting it to a predetermined length after cutting off both ends.
- Patent Document 2 proposes a technique for winding a glass film ribbon formed by a so-called float method, which is obtained by cutting both ends in the width direction of a glass film ribbon on a molten tin tank into a roll. ing.
- a glass film ribbon can be wound into a roll shape by taking advantage of its excellent flexibility, and supplied to a production system such as a Roll to Roll manufacturing method, for example. Is possible.
- the glass film ribbon is formed into a thin plate shape, and is further drawn while its viscosity is relatively low, and is formed into a predetermined width direction dimension and thickness dimension. At this time, the glass film ribbon may be warped or bend with a large curvature in the width direction of the glass film ribbon. In many cases, when a glass film ribbon is formed, these deformations appear in a combined form. And these deformation
- Patent Document 1 by incorporating a mechanism for monitoring and adjusting the degree of curved deformation (including the presence or absence of curved deformation) of the glass film ribbon into the glass film ribbon forming apparatus, A technique for preventing the glass film ribbon from being bent is disclosed.
- a device for monitoring the degree of curve deformation of the glass film ribbon is installed at a location where the glass film ribbon is sufficiently or cooled to some extent. As described above, the deformation of the glass film ribbon occurs until the molten glass is formed into the shape of the glass film ribbon and finishes cooling, and is fixed, so that the glass film ribbon already cooled by the monitoring device is fixed.
- the technology to be solved by the present invention to accurately manufacture a glass film ribbon that can be wound into a roll without causing a decrease in yield and without being deformed by bending.
- this manufacturing method forms a glass film ribbon from molten glass or a glass base material for secondary processing, winds the glass film ribbon drawn downward with cooling into a roll shape, and winds the position.
- the vertical distance from the glass film ribbon forming start position to the glass film ribbon cutting position is the width dimension of the glass film ribbon. It is characterized by a point that is more than 5 times.
- the “glass film ribbon forming start position” referred to here varies depending on the molding method employed. For example, when the slot down draw method is employed as the glass film ribbon molding method, the molten glass is drawn downward.
- the slot (slit) opening for this corresponds to the molding start position. If the overflow downdraw method is adopted, the lower end of the molded body where the overflowing molten glass joins corresponds to the molding start position, and if the redraw method is adopted, a secondary such as a burner is used. A position at which the glass base material for processing is heated to start stretching in a predetermined direction corresponds to the molding start position.
- the glass film ribbon drawn downward with cooling is subjected to glass drawn downward in addition to the pulling force by a roller for winding the glass film ribbon into a roll shape.
- the weight of the film ribbon is added to the glass film ribbon itself. That is, when viewed on the basis of a predetermined part (for example, a part being cooled) of the glass film ribbon drawn out along the vertical direction, the weight of the part located below the predetermined part is the above-mentioned value of the glass film ribbon. It becomes the pulling force in the vertically downward direction with respect to the predetermined part.
- This traction force should act evenly in the vertical direction and over the entire width direction of the glass film ribbon, but the glass film ribbon warps or deforms for some reason, so that its center of gravity is at the molding start position. May deviate from the virtual vertical line passing through. At this time, if the above-mentioned traction force is insufficient, such a state continuously occurs over a long period of time, and even if a force that tries to return the center of gravity of the glass film ribbon to the virtual vertical line is applied after that, Due to the time delay, the glass film ribbon remains largely deformed, which can lead to fatal defects in quality.
- the present inventor as described above, the ratio between the vertical distance from the glass film ribbon forming start position to the cutting position along the width direction of the glass film ribbon and the width dimension of the glass film ribbon.
- the ratio is a predetermined size or more, specifically, when the ratio is 5 or more, a glass film
- the force for returning the center of gravity of the ribbon to the vertical line acts quickly and effectively on the glass film ribbon before winding without causing a time delay. Therefore, for example, when producing a glass film ribbon having a predetermined width direction dimension, a glass film continuously formed by taking a large vertical distance according to the width direction dimension of the glass film ribbon.
- the deformation including the curved deformation of the glass film ribbon to be produced can be reduced as much as possible. Therefore, even if a monitoring device and an adjusting mechanism are not particularly provided, when the glass film ribbon is cut along the width direction and wound into a roll shape, it is not necessary to shift to a so-called bamboo shoot shape.
- the gravity center position of the glass film ribbon being pulled out is adjusted by its own weight, so once the ratio of the vertical distance to the width direction dimension is determined, It becomes possible to continue production of a long glass film ribbon stably. Accordingly, by winding up the long glass film ribbon, it is possible to stably obtain a highly accurate glass film winding roll in a state where the winding positions in the width direction are always aligned.
- the thickness dimension at the center in the width direction of the glass film ribbon may be 300 ⁇ m or less.
- the thickness dimension of the glass film ribbon to be rolled up exceeds 300 ⁇ m
- the inner diameter of the roll body of the glass film should theoretically be 420 mm or more (preferably 700 mm or more), and the glass after winding This is because the outer diameter of the roll tends to exceed 2000 mm, and it becomes practically difficult to transport the glass roll by a container or the like.
- the thickness dimension of the central portion in the width direction of the glass film ribbon is preferably 300 ⁇ m or less, more preferably 100 ⁇ m or less, and more preferably 50 ⁇ m or less. Further preferred.
- an overflow down draw method may be adopted as a method for forming a glass film ribbon from molten glass.
- a rolled product of a glass film obtained by winding a glass film ribbon into a roll is often supplied to a subsequent process related to the so-called Roll to Roll manufacturing method.
- An operation of providing fine elements and wiring on the surface of the film ribbon is performed. Therefore, very excellent smoothness (flatness) is required on the surface of the glass film ribbon.
- the shape of the inner surface of the molding nozzle slot is reflected on the surface of the glass film ribbon to be molded in order to discharge the molten glass from the molding nozzle. May end up. Therefore, it is difficult to obtain a smooth and highly accurate surface of the glass film ribbon.
- the surface of the glass film ribbon only needs to come into contact with the outside air (atmospheric gas in the molding apparatus), and thus a very smooth surface can be obtained. Similar effects can also be obtained by a so-called redrawing method in which the glass base material for secondary processing once solidified is heated and stretched in a predetermined direction.
- both ends in the width direction of the glass film ribbon may be cut by laser cleaving.
- the thickness dimension at both ends in the width direction is mainly the width direction center part used as a product part. It is often thicker than the thickness dimension. For this reason, when manufacturing a glass film ribbon for the purpose of obtaining the glass film product which has a fixed thickness dimension, the width direction both ends of the shape
- the method using laser cleaving can be mentioned as one of the suitable methods of cutting the width direction both ends of a glass film ribbon.
- the side end surfaces generated by cutting both ends in the width direction by laser cleaving are smooth and very few scratches, so that they are suitable for glass film ribbons for glass roll products.
- the laser cleaving means that a thermal stress caused by heating by a laser and cooling by a refrigerant is generated in the glass film ribbon, and the initial crack previously applied to the glass film ribbon is propagated by this thermal stress.
- the glass film ribbon is cut by. According to the present invention, since there is no fear that one of the both end portions in the width direction of the glass film ribbon is lifted at the time of cutting, the both end portions can be cut reliably and with high accuracy.
- the vertical distance of the slow cooling region located below the glass film ribbon molding start position is 50% to 80% of the vertical distance from the glass film ribbon molding start position to the glass film ribbon cutting position. The following should be set.
- the vertical distance of the slow cooling region is preferably 60% or more and 80% or less, more preferably 70% or more and 80% or less of the vertical distance from the glass film ribbon forming start position to the cutting position.
- this manufacturing apparatus winds a glass film ribbon forming apparatus for forming a glass film ribbon from molten glass or a glass base material for secondary processing, and a glass film ribbon drawn downward with cooling in a roll shape.
- a glass film manufacturing apparatus comprising: a winding device for taking up; and a width direction cutting device for cutting the glass film ribbon along the width direction before the winding position by the winding device. It is characterized by the fact that the vertical distance from the forming start position to the cutting position of the glass film ribbon by the width direction cutting device is 5 times or more the width direction dimension of the glass film ribbon.
