INSTRUCTIONS: This application claims the priority of US Provisional Application No. 61/286,961, filed on Dec. 16, 2009. TECHNICAL FIELD OF THE INVENTION The present disclosure relates to a method and apparatus for separating a glass sheet from a curved glass ribbon that has been scored by laser. The following discussion relates to a glass ribbon that moves in a vertical direction, which is a typical application of the methods and apparatus disclosed herein. However, this direction is only intended to assist in the description and should not be construed as limiting the disclosure in any way. [Prior Art] It is customary to use mechanical tools to complete the marking of the glass. However, there are alternatives that use laser light strikes, for example, C 〇 2 laser radiation at a wavelength of 1 〇 6 to heat the glass and create a tensile stress via a temperature gradient. The use of lasers for the characterization of glass is described in US Patent No. 5,776,220, entitled "Method and apparatus for breaking brittle materials," and "rc〇ntr〇i of median crack depth in laser scoring". Discussed in U.S. Patent No. 6,327,875. As shown in Fig. 1, a vent is created in the major surface 114 of the glass 112 along the reticle 115 during laser scribing. In order to create the through hole, a small initial crack m is formed on the surface of the glass near one edge of the glass surface 201125671, and then a small initial is formed by diffusing the laser beam 121 generated by the laser 141 and having the footprint 113 across the glass surface. The crack 111 is converted into a through hole, and then a cooling zone is generated by cooling the nozzle 丨丨9. Heating the glass with a laser beam and then immediately quenching it with a coolant creates a thermal gradient and a corresponding stress field that is responsible for the formation of vias that cause the initial crack to grow. A system for laser scribing of a moving glass ribbon is described in US Patent Publication No. 2/8,994,994 (the '994 publication), in which a carriage is moved along a linear track, relative to The line that crosses the direction of motion of the glass ribbon is linearly oriented at an angle. tilt. Figures 2 and 3 of this application outline the solution and the system of the 994 publication. In these figures, the symbol 13 indicates a glass ribbon, the symbol 14 indicates that the bracket 'symbol 丨 5 indicates a linear track 'symbol 丨丨 indicates a support structure (support frame) for the track' and the symbol 9 indicates production glass. For example, a fusion draw machine. As discussed in the '994 petition, viewed from a fixed reference coordinate (for example, the xyz reference coordinate in Figure 2), the glass ribbon moves in the direction of the vector Μ in speed s glass, and the carriage is fast 纟The bracket moves in the direction of the vector ,, the middle „, 丫b breaking, the S bracket and the angle α satisfy the following relationship: S bracket = S "Wsina. Equation (1): In this mode, the bracket is kept in synchronization with the glass ribbon, or more precisely, the magnitude of the velocity component of the bracket parallel to the direction of movement of the ribbon is 201125671 (magnitude) is equal to ς ... ". So, from the glass belt, the bracket is simply given the following formula and S * '丨" moves in the direction of vector 18, that is, along the _ + + mouth perpendicular to the glass ribbon Ribbon: ▼ 妁 妁 方向 方向 7 7 7 7 7 7 7 7 7 7 7 7 7 S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S And the nozzles providing the cooling fluid (for example, water, &) are coupled to the bracket, and the carrier is moved along the linear track, and the __ temple forms a through hole spanning the width of the glass ribbon. In some embodiments, a 'm-ng head' (eg, a 'scratch wheel) also engages the bracket to form an initial crack in the glass ribbon. The 戎, 丄 丄 & The initial crack is formed by the equipment separated from the bracket. Figure 4 is a summary of the map, the 994 disclosure of these aspects, The component symbols 2b 22 and 23 represent (1) the footprint of the cooling fluid, (7) the footprint of the laser beam, and (7) the initial crack at the beginning of the scribing process, and the component symbols 31 and 32 represent the later after the initialization has been completed. The point in time, the footprint of the cooling fluid and the position of the footprint of the laser beam. In terms of cutting a separate piece of glass 13 from the glass ribbon 33, the 994 publication relates to the use of conventional bending techniques, and the automatic suction of the suction cup The machine grasps the glass ribbon under the engraved line and bends the glass ribbon, causing it to separate at the score line. According to the disclosure (see below), it has been found that the engraved line produced by the laser is separated from the mechanical scoring device. The resulting engraved lines have different characteristics of 201125671. Therefore, the bending technique of glass ribbons successfully used for mechanical scribing since the county's 々 入 has been found to cause poor edge quality for laser-scribed glass ribbons.

According to the thirteenth aspect, in the first to tenth methods, the convex portion is flat upward in either of the two sides of the glass ribbon. [Embodiment] As described above, the present disclosure relates to the discovery that the score line generated by the laser has a different characteristic from the score line produced by the mechanical scoring apparatus. Therefore, when the mechanical scoring device produces a score line, it physically moves the glass bowl on the surface of the glass surface, at the line and below. "There are many particles that can be found buried in the glass at the scribe line and near the scribe line. As a result, if the mechanically scribed glass is simply allowed to remain as it is, even if no bending force is applied. , which usually also spontaneously separates at the mechanical score line, that is, the physical damage suffered by the glass and the stress caused by the particles pressed into the glass at the score line by the mechanical scoring device will cause The result of spontaneous separation of the glass. The reticle formed by the laser is very different. First, the laser usually does not remove the glass material from the reticle 'it does not occur in the granules buried in the glass near the reticle Conversely, the laser operates by attenuating the chemical bonding at the point where the laser and cooling fluid act. If it is allowed to maintain the status quo, rather than spontaneously separating, the laser-engraved line actually heals, especially in wet conditions. In the atmosphere, the water in it can participate in the re-formation of chemical bonds. Therefore, it has been found to separate from the glass ribbon at the line marked by the laser. 201125671=The slab is substantially different from the Separating the glass at the line of mechanical scoring In particular, for glass ribbons with curvature, glass bending procedures that have long been successfully used for mechanical scribing lines have been found during the glass sheet separation process. When applied to a laser-engraved line, it produces poor edge quality, and all other cases are equal. In fact, it has been found that the edge product f becomes very poor and a large percentage of the product glass cannot be used in anticipation. Use, for example, as a substrate for a liquid crystal display. According to the disclosure of the present invention, by modifying the bending process, the portion of the glass ribbon containing the reticle is not substantially flattened before being laser-marked. The beginning of the separation at the line can overcome the situation where the traditional bending technique cannot be used for the laser-engraved line. In practice, where the glass is scratched and the separation occurs (usually referred to as "stretching the bottom" Bcm〇m 〇f ^心(四)" or B〇D), the glass ribbon has a non-flat across shape (across_the_draw shape), especially for thin glass (for example, having a thickness of 0.7 mm or less) This is especially true for glass ribbons that are composed of glass and have a large width (10), such as 0.5 meters or more. For example, the glass ribbon can be arcuate' its concave surface can be on either side of the glass ribbon. It is also possible for the glass ribbon to assume a more complex shape, such as a dome or a W shape. Figures 6 and 6 illustrate an example of an arcuate glass ribbon 33 in which the concave surface of the glass ribbon faces the suction cup 51 of the sheet engaging assembly 530 and the frame 52A. As shown in these figures, the suction cup 510 and the projection 540 engage the 13 201125671 first side 502 of the glass ribbon 33. Although the suction cup is used as the tape/sheet holding device in Figures 5 and 6, it should be understood that the 'holding device may have a variety of other configurations known or to be developed in the art to which the present invention pertains. For example, as shown in Figure 11 i 15 , the retaining device may comprise a pad of ###, and a pad of the second side of the glass ribbon, and a glass ribbon of the eleventh of the first side of the glass ribbon. The suction cup on the second side can be replaced by a blanket so that the glass ribbon is clamped between sets of profiles that are joined to opposite sides thereof as another variation. As shown in Fig. 7, during the separation process, the sheet-engaging assembly 530 can be used as a rotating terminator or fulcrum by, for example, the industrial robot 1700, rotating around the axis of the score line. In the figure, the "5th and 6th patterns" are laser-engraved at the first side 501' of the glass ribbon, that is, the side opposite the convex portion 54〇, and the frame and the tape/sheet holding device ( The suction cup in this particular embodiment rotates clockwise n as seen in the sixth® 'because the glass ribbon is not flat, there is a gap 56〇 between the convex portion 54〇 and the second side 502 of the glass ribbon. The sheet-engagement assembly 530 Rotate the bending moment to the score line of the glass ribbon. When the bending moment becomes large enough, that is, when the stress caused by the bending in the glass exceeds the breaking S stress of the glass, the glass ribbon breaks at the score line. The glass sheet is thus released from the glass ribbon. A further description of the bending process can be found in the 'U.S. Patent No. M16'025, the entire disclosure of which is incorporated herein by reference. 14 201125671 Initially, the unevenness of the glass ribbon at the convex portion, for example, the presence of the gap 560 in Fig. 6, is not considered to be related to the poor edge quality that can be seen by the laser scribing. However, through experimentation and computer analysis, it can be judged that flatness actually causes poor edge quality. In particular, it has been found that if the glass ribbon is in an uneven state at the beginning of the glass sheet separation process, a large amount of shear stress develops along the line of the laser-engraved line. When the separation of the glass sheets releases the shear stress, jagged edges are created. In the case of mechanical scoring, the relatively simple separation of the reticle limits the amount of stress including the amount of shear stress that can be generated after the knife is removed, so that even for non-flat glass ribbons, the resulting edge quality can be accept. On the other hand, in the case of laser scoring, the amount of stress allowed for a relatively difficult-to-separate reticle, including the amount of shear stress, grows to a degree sufficient to produce jagged edges. Experiments and computer analysis further show the stress at the reticle, which is related to the distance L between the scribe line and the closest strip/piece holder of the sheet-engagement assembly (in this particular embodiment, the suction cup) (see item 1) 〇图). In particular, it has been experimentally observed that the separation must always begin in the region of the score line, with the score being above or adjacent to the position of the holding device (e.g., the suction cup). Computer analysis shows that the principal stress intensity at the reticle at this location depends on the distance L. This effect is illustrated in Figure 8, where the vertical axis shows the first principal stress (arbitrary unit) at the calculated score line and the horizontal axis shows the distance (also in arbitrary units) calculated from the center of the glass ribbon. The inner and outer edges of the holding device 201125671 (suction cup) are indicated by vertical lines 810 and 82. Curve 800 shows the calculated stress distribution baseline for the L value suitable for mechanical scoring, while curves 801 & 802 show the effects of the decrease and the near (10), respectively. As shown, the increase in enthalpy reduces the stress at the reticle (curve 8G2)' while decreasing L increases the stress at the reticle (plot 801). From this analysis, it can be seen that by moving the closest tape/sheet holding device further away from the score line, the strength of the stress generated by the place can be reduced. This means that the sheet-engagement assembly can begin to advance along the separation of the glass sheets - steps around the score line. Because such rotation causes the glass ribbon to lie flat against the convex portion, and in particular, since the greater degree of rotation is equivalent to flattening, the stress generated by increasing the L reduction allows the rotation of the engaging member to be large enough. The top is completely flat against the tenon before the separation begins. The flattening effect associated with the rotation of the sheet-engagement assembly is illustrated in Fig. 9, wherein the gap 560 is substantially reduced as a result of the rotation as compared to Fig. 6. The stepwise rotation will bring the glass into contact with the six parts, thus providing the desired substantially complete flat configuration. In this way, that is, by the force increasing port L, when the stress caused by the rotation eventually exceeds the glass When the stress is broken, the glass ribbon will flatten against the projections and will therefore not be subjected to a large amount of shear stress. Without a large amount of shear stress, the edge of the glass piece will not be jagged, which is ... from the laser-engraved glass ribbon to produce two-edge quality 201125671 This method relies on the convex portion to remain flat across the glass ribbon. However, it has been found that the edge quality can be further improved if the convex portion has a cross-section and a secret cross-section such that the second side of the glass ribbon is in contact with the convex portion substantially along a single line. The convex portion thus curved is shown in the first figure. In the figure, the symbol 570 shows the direction of rotation of the sheet-engaging member 53A. The curved projections can be fixed or can be rotated about an axis parallel to the score line. A variety of materials are available for the projections. Among them, a suitable material is a broken rubber. Similarly, the convex portion of the f curvature can have a variety of curvatures. For example, it has been found that a diameter of 50 mm is suitable for a projection having a circular transverse section. Although it has a curved material to increase the edge, it can be used with other cross-sectional shapes (for example, square): = flattened aspect of the disclosure. In practice, 'the gap can be determined by observing the gap 560 and increasing L until the separation is blocked by a sufficient amount' causing the gap to close and the second side 502 of the glass ribbon to contact the protrusion before the separation begins. The strip/sheet maintains a distance W between the jaws which produces an acceptable edge quality. Alternatively, the edge quality itself can be determined as to whether L is large enough to increase the incidence of the jagged edges to a desired degree, for example, until there are substantially no dentate edges. In either case, the adjustment of 'L is simple and easy to understand, especially when the film-joining assembly is operated by the Weifang automaton, in which the change of L can be done by changing one or more operating parameters of the automaton. . 17 201125671 It should be noted that 'because the longer L means that the sheet joint assembly 530 needs to rotate further around the score line before the split occurs, the action rate of the glass ribbon 33 sets an upper limit on the increase in L. With respect to a given rate of rotation (e.g., a rate of rotation that can match the elastic properties of the glass), the rotating sheet assembly 530 takes longer and, therefore, at some point in time, the speed of the separation process Will be behind the speed of glass ribbon production. However, in practice, it has been found that L can be increased to the extent that substantially eliminates the problem of jagged edges while still maintaining the rate at which the ribbon operates. 11 through 16 illustrate a specific embodiment of an apparatus for carrying out the above method for enhancing the edge quality of a glass sheet separated from the glass ribbon at the line of the laser scribing. This apparatus also illustrates a further aspect of the present disclosure in which the projections are integrated with the glass sheet handling equipment, the glass sheet handling equipment: (1) applying a bending moment to separate the glass sheets from the glass ribbon, and (2) moving the separated glass sheets Leave the glass ribbon and (3) transfer the separated glass sheets to the conveyor equipment that engages the top of the glass sheets. Such integrated projection/glass sheet handling components reduce cost and simplify the equipment components at the bottom of the stretch. In addition to the use as a pivot (fulcrum) for the glass ribbon bending process, it is also possible to use the projection of the integrated component as a support (baeking) for forming an initial crack (see symbol 4 in Figure 4), or as A support for the entire scoring process that performs mechanical scoring rather than laser scribing. When used only for the formation of initial cracks in the first 18 201125671 and not as a mechanically scored slab of the full width of the glass ribbon, it is not necessary to extend across the full width of the glass ribbon, but only the initial crack. The fulcrum of the separation or as a span, the projections of the assembly need to be long enough to make the integration of the figures 11 to 16 and the parts can be operated by an industrial robot, where the components are, for example, the nominal center of the equipment (n〇minaUente〇67) The raft is attached to the automaton. As shown in Figure 15, the assembly may include a vacuum 帛 62〇' positioned above and below the projection to collect the shards of glass produced when the glazing is separated from the glass ribbon. A vacuum system (not shown) is connected through a vacuum duct (Chuan plenum) 630. The integrated assembly may also include a connector assembly 650 of the type described in U.S. Patent No. MA025, which relates to the above When it occurs, it can allow the separated glass sheets to automatically descend away from the traveling glass ribbon. As described above, in one embodiment, the assembly can use a glass wafer drop unit 660 that utilizes the second side of the glass ribbon 5 The suction cup of 〇2, and the clamping pad of the first side 5〇1 of the glass ribbon. The pneumatic cylinder 680 is used to move the clamping pad against the glass ribbon. In practice, the suction cup can be brought to the second of the glass ribbon. side And then let Xiao Yan hold the pressure to press the glass against the suction cup. The combination of the suction cup and the clamping pad can increase the support capacity and widen the process window. For example, the equipment can be used for stretching. The bottom shows a large and skewed ribbon of the bow and reduces the suction of the suction cup. When there are projections, the pad and the suction cup can be made of various material groups 201125671, including, for example, silicone rubber. Integrated convex/glass sheet operating components Also included is an air cylinder 64〇 that moves the tenon into and out of the plane defined by the glass gripping unit, that is, the nominal plane of the second side of the glass ribbon when the glass ribbon has been engaged with the glass gripping unit (n) 〇minal plane). In particular, when the glass ribbon is erected during mechanical scribing and separation of the glass sheets, the convex portion needs to be positioned in this plane, but during the transfer of the glass sheet to the subsequent operation, the convex portion needs to be located Outside this plane, to expose the top edge of the glass sheet. In an extended configuration (see Figures 11 through 14), the air vapor moves the convex part into the plane, in the retracted configuration (see Figure 15) ,allow #去软知m } The toilet cylinder moves the convex part away from the plane to expose the top edge 690. When the bran, 昤 筮,, Tian Ran, other linkages other than those shown in Figures 11 to 5 are also used Moving the convex portion between the two positions of the convex portion, for example, can be achieved by a servo motor. The representative action of the self-moving glass ribbon separating the glass sheet A and the integrated convex/glass sheet operating assembly 1% of the brothers 11 to 丨 5 in the figure. The nth picture shows the components before the glass material is joined, and the 12th riding shows the components after the connection with the glass ribbon. Once connected with the broken glass ribbon, along with the initial crack Formation and laser scoring, the motive moves down the component against the glass ribbon. Thereafter, the automaton rotates the assembly around the factory silver (or specifically around the leading edge of the projection) to first bring the ribbon卞—The sinner's convex part, and then separate the glass piece from the glass ribbon. Figure 13 is not the result of the system after the broken glass is separated from the glass ribbon. Thereafter, the automatic 20 201125671 machine moving assembly and the separated glass piece shown in Fig. 14 are separated from the glass ribbon. Finally, in Fig. 15, the gas 640 moves the convex portion away from the glass sheet/the side/the next operational device can engage the glass sheet from above. The automaton then returns to the position as shown in Fig. U, and repeats the above process for the τ_ patch. It will be apparent to those skilled in the art to which the present invention pertains that various modifications of the invention are possible without departing from the scope of the invention. The scope of the following patent application is intended to cover the specific embodiments of the invention, as well as the modifications, variations, and equivalents thereof. 21 201125671 [Simple description of the diagram] Figure 1 is a schematic diagram depicting the laser scribing process.
