JP 2004-351655 A

  For example, Patent Document 1 proposes a glass plate perforating method and apparatus for forming holes in a glass plate.

  By the way, when drilling a relatively thin glass plate such as for a plasma display (PDP) or a liquid crystal display (LCD) using a diamond drill, the rotationally driven diamond drill contacts the surface of a hard glass plate. In doing so, for example, as shown in FIG. 6, there is a possibility that the diamond drill 2a will oscillate with respect to its rotational axis, and the peripheral edge of the hole formed in the glass plate 1a may be chipped. Further, during the formation of the hole in the glass plate by the diamond drill, for example, as shown in FIG. 7, the peripheral edge 31a of the hole 3a formed in the glass plate 1a by the cutting powder 32a discharged from the hole 3a being formed. There is a risk of chipping. In the case of forming fine holes in the glass plate, since a diamond drill having a small diameter is used, the probability that the peripheral edge of the fine holes formed in the glass plate is chipped can be increased. Since glass plates for plasma display (PDP), liquid crystal display (LCD), etc. can be commercialized without chamfering the periphery of the hole, it is not desirable that there is a risk of chipping as described above. . In addition, when drilling a glass plate with a synthetic resin resin film, such resin film is also ground by a diamond drill that is rotationally driven. There is a possibility of clogging due to (cutting powder), particularly cutting powder of a resin-based film containing an adhesive.

  The present invention has been made in view of the above points, and the object of the present invention is to eliminate the possibility of chipping at the periphery of the hole in the glass plate and to eliminate clogging of the diamond drill. It is an object to provide a method and an apparatus therefor and a bonding member used therefor.

  In the method for perforating a glass plate of the present invention, a diamond drill is formed between a synthetic resin-based film disposed at a site where a hole is to be formed on one side of the glass plate and one side of the glass plate. Forming a hole by arranging a rubber plate for dressing and forming a hole in the part of the glass plate on which the rubber plate is arranged through a hole in the resin-based film and the rubber plate by a rotationally driven diamond drill The diamond drill is later extracted from the hole formed in the glass plate.

  According to such a method of drilling a glass plate, the rotation of the diamond drill that is driven to rotate with respect to the surface of the hard glass plate is prevented by the resin-based film from rotating with respect to the rotation axis of the diamond drill. When the driven diamond drill comes into contact with the surface of the hard glass plate, it is possible to eliminate the possibility of chipping at the peripheral edge of the hole formed in the glass plate. By using the diamond drill having a small diameter, for example, a liquid crystal display for a plasma display (PDP) can be eliminated. Even when micropores are formed in a glass plate for (LCD) etc., chipping occurs at the periphery of the micropores formed in the glass plate. The probability can be eliminated in the same manner as described above, and since the rubber plate for dressing is interposed between the glass plate and the resin film, the resin resin film made of synthetic resin is driven to rotate in the opening of the glass plate. The clogging of the diamond drill due to the chip of the resin-based film made of an adhesive synthetic resin that can occur when grinding with a diamond drill can be removed by dressing the diamond drill with a rubber plate.

  In another method for punching a glass plate of the present invention, a rubber member for dressing a diamond drill and a resin member made of a synthetic resin are bonded to each other, and the rubber plate is a glass plate and a resin film. The hole on one surface of the glass plate is to be formed so as to be interposed between the glass plate, and the hole in the resin film and the rubber plate is formed in the portion of the glass plate by a diamond drill that is driven to rotate. A hole is formed through the hole, and after the hole is formed, the diamond drill is extracted from the hole formed in the glass plate.

  According to another method for punching such a glass plate, in particular, a rubber plate for the bonding member is formed by bonding a rubber plate for dressing a diamond drill and a resin film made of a synthetic resin. Since the hole is formed on one surface of the glass plate so as to be interposed between the glass plate and the resin-based film, the rotationally driven diamond drill is placed on the surface of the hard glass plate. The resin-based film can prevent the diamond drill from wobbling with respect to the rotation axis when contacting, and the periphery of the hole formed in the glass plate when the rotationally driven diamond drill contacts the surface of the hard glass plate. The possibility of chipping can be eliminated, and the chips produced in the holes being formed are discharged through the resin film, so that It is possible to eliminate the possibility of chipping at the periphery of the hole formed in the glass plate. For example, by using a diamond drill with a small diameter, fine holes are formed in a glass plate for plasma display (PDP), liquid crystal display (LCD), etc. Even in the case of forming, the probability of causing chipping at the periphery of the fine holes formed in the glass plate can be eliminated in the same manner as described above, and the rubber plate for dressing is interposed between the glass plate and the resin film. In addition, in the drilling of a glass plate, the diamond drill's eyes are formed by cutting a synthetic resin resin film containing an adhesive that may be generated when a synthetic resin resin film is ground by a rotationally driven diamond drill. The clog can be removed by dressing a diamond drill with a rubber plate.

  In yet another method of drilling a glass plate of the present invention, a synthetic resin resin film is rotated by a diamond drill that is rotationally driven to the portion of the glass plate that is attached to a portion where a hole is to be formed on one surface. A hole is formed through a resin film, and after forming the hole, a diamond drill is removed from the hole formed in the glass plate, and a diamond drill dressing rubber plate is prepared separately. After completion, in order to dress the diamond drill, a step of punching the separately prepared rubber plate with the diamond drill is provided.

  According to such another drilling method, when the rotationally driven diamond drill comes into contact with the surface of the hard glass plate, the rotation of the diamond drill with respect to its rotational axis is prevented by the resin film. When the driven diamond drill comes into contact with the surface of the hard glass plate, it is possible to eliminate the possibility of chipping at the peripheral edge of the hole formed in the glass plate. By using the diamond drill having a small diameter, for example, a liquid crystal display for a plasma display (PDP) can be eliminated. Even when micropores are formed in a glass plate for (LCD) etc., chipping occurs at the periphery of the micropores formed in the glass plate. In addition, the rubber plate for dressing the diamond drill can be prepared separately, and after the hole forming process, the diamond drill can be dressed after the hole forming process by using the diamond drill. Since it is equipped with a process of opening, clogging of the diamond drill due to synthetic resin resin film chips caused by grinding with a rotationally driven diamond drill can be caused by dressing the diamond drill with a rubber plate. Can be removed.

  The glass plate perforating apparatus of the present invention is provided with a rubber plate for dressing a diamond drill at a portion where a hole is to be formed on one surface of the glass plate, and a synthetic resin resin system on the rubber plate. A hole is made in the portion of the glass plate on which the film is arranged through a hole in the resin film and the rubber plate by rotation of the diamond drill.

  Another punching device of the glass plate of the present invention is a bonding member in which a rubber plate for dressing a diamond drill and a resin-based film made of synthetic resin are bonded together, and the rubber plate of the bonding member is a glass plate. Perforating the resin film and rubber plate in the part of the glass plate placed on the part where the hole is to be formed on one surface of the glass plate so as to be interposed between the resin film and the resin film. A hole is made by rotation of the diamond drill.

  Still another punching device for the glass plate of the present invention is a method in which a synthetic resin-made resin-based film is placed on a portion of a glass plate on which a hole on one surface is to be formed with a diamond through the resin-based film. A drilling device for a glass plate configured to perform drilling by rotating a drill, and dressing a drilled diamond drill after drilling a portion of a glass plate of a resin-based film by rotating the diamond drill In addition, holes are made in a separately prepared rubber plate, and other portions of the glass plate are made through a resin film by rotation of a diamond drill that has made holes in the rubber plate. .

  A laminating member for perforating a glass plate according to the present invention includes a resin-based film made of a synthetic resin and a rubber body bonded to one surface of the resin-based film. According to such a bonding member, it is possible to eliminate the possibility of chipping at the periphery of the hole of the glass plate in which the hole is formed by the diamond drill, and it is possible to remove clogging that may occur in the grinding of the resin-based film by the diamond drill. The glass plate can be perforated in a short time.

  According to the present invention, it is possible to eliminate the possibility of chipping at the peripheral edge of the hole in the glass plate, and also to provide a method and apparatus for drilling a glass plate that can eliminate clogging of a diamond drill, and a laminating member used therein Can be provided.

  Next, the present invention will be described in more detail based on an example of a preferred embodiment shown in the drawings. The present invention is not limited to these examples.

  1 to 5, reference numeral 1 is a glass plate for a plasma display (PDP) or a liquid crystal display (LCD), reference numeral 2 is a diamond drill for forming a hole 3 in the glass plate 1, and reference numeral 4 is a glass plate 1. It is the bonding member affixed on one side 5 of.

  In this example, the diamond drill 2 has a small diameter so that fine holes (fine holes) 3 can be formed in the glass plate 1. Such a diamond drill 2 is rotationally driven in the R direction by rotational driving means comprising an electric motor or the like. The diamond drill 2 may be always driven to rotate by a rotation driving means, and is rotated immediately before the start of grinding for forming the hole 3 in the glass plate 1 (immediately before the contact of the diamond drill 2 with the bonding member 4). The rotation drive may be terminated after the driving is started and the hole 3 is formed or after the diamond drill 2 is extracted from the hole 3.

  In this example, the bonding member 4 includes a resin-based film 11 made of synthetic resin and a rubber plate (rubber dress plate) 13 bonded to the surface 12 of the resin-based film 11 on the glass plate 1 side. In the rubber plate 13 for dressing the diamond drill 2, it is attached to a portion 14 where the hole 3 in the surface 5 of the glass plate 1 is to be formed. The rubber plate 13 is attached to the surface 5 of the glass plate 1 on the surface 15 on the glass plate 1 side. The surface 15 of the bonding member 4 and the surface 16 on the diamond drill 2 side only need to have an area enough to cover the region 14 and the peripheral edge thereof. In this example, the surface 15 of the glass plate 1 It has the same or larger area. The bonding member 4 may be bonded to all areas of the surface 5 by the surface 15.

  In the method for punching a glass plate of this example, as shown in FIG. 1, first, a glass plate 1 having a bonding member 4 attached to a surface 5 is prepared and the glass plate 1 is provided with a support base for forming holes ( (Not shown). The glass plate 1 may be supported by a support base for hole formation (not shown) after the pasting member 4 is pasted on the glass plate 1 in advance, and further pasted after being supported by such a support base. The member 4 may be affixed.

  Next, with respect to the glass plate 1 on which the laminating member 4 is placed and pasted, the diamond drill 2 is moved in the XY plane coordinates by the drill moving means so that the tip 21 of the diamond drill 2 is the glass plate 1. It arrange | positions above the site | part 14 so that the site | part 14 may be opposed in the Z direction orthogonal to the surface 5. Next, the arranged diamond drill 2 is rotationally driven in the R direction around the rotational axis 22 extending in the Z direction by the rotational driving means, and the rotationally driven diamond drill 2 is moved toward the glass plate 1 by the drill moving means toward the glass plate 1. The tip 21 of the diamond drill 2 is brought into contact with the surface 16 of the resin film 11 of the bonding member 4 attached to the surface 5 of the glass plate 1 as shown in FIG.

  The diamond drill 2 in contact with the resin film 11 further moves in the Z direction toward the glass plate 1, grinds while pressing the resin film 11, and subsequently grinds the rubber plate 13 to remove the glass. It reaches the surface 5 of the plate 1.

  The diamond drill 2 that has reached the surface 5 of the glass plate 1 starts grinding the portion 14 following grinding of the rubber plate 13. At this time, since the bonding member 4 is present around the diamond drill 2 as shown in FIG. 3, the bonding member 4 prevents the deflection of the rotation axis 22 of the diamond drill 2 from occurring.

  Since the diamond drill 2 for grinding the portion 14 of the glass plate 1 is moved in the Z direction toward the glass plate 1, the resin-based film 11 pressed in the Z direction toward the glass plate 1 by this movement It bites into one side, is interposed between the rubber plate 13 and the diamond drill 2, and bites into the peripheral edge 31 in the middle of formation in the glass plate 1 as shown in FIG. The resin film 11 digging in in this way prevents the chips 32 generated in the holes 3 of the glass plate 1 being formed by the diamond drill 2 from coming into contact with the peripheral edge 31 and promotes the discharge of the chips 32.

  As described above, the hole 3 is formed in the portion 14 of the glass plate 1 by grinding with the diamond drill 2 as shown in FIG. After the formation of the hole 3, the diamond drill 2 is moved in the Z direction so as to be separated from the glass plate 1 by the drill moving means and is extracted from the hole 3. In this extraction, the bite portion of the resin film 11 is separated from the glass plate 1 and is also extracted from between the rubber plate 13 and the diamond drill 2. As a result, the rubber plate 13 is exposed to the diamond drill 2, so that when the diamond drill 2 is driven to rotate, it is ground again by the diamond drill 2, and the diamond drill 2 is caused by this grinding. The clogging is obtained, and in particular, the clogging due to the chips 32 caused by the adhesive applied to the resin film 11 is removed. The bonding member 4 is peeled off from the glass plate 1 in which the holes 3 are formed.

  According to the method for perforating the glass plate of this example, the bonding member 4 formed by bonding the rubber plate 13 for dressing the diamond drill 2 and the resin-based film 11 made of synthetic resin is used as the rubber of the bonding member 4. The plate 13 is placed between the glass plate 1 and the resin film 11 so that the hole 3 in the one surface 5 of the glass plate 1 is to be formed, and the bonding member 4 is placed. The portion where the hole 3 in the one surface 5 of the glass plate 1 is to be formed in the Z direction intersecting the one surface 5 of the glass plate 1 with the diamond drill 2 that is rotationally driven with respect to the placed glass plate 1 The hole 3 is formed in the portion 14 through the holes made in the resin film 11 and the rubber plate 13 by moving relatively to the position 14, and after the formation of the hole 3, the diamond drill 2 is reverse to the above movement. Moved in the direction In order to extract the diamond drill 2 from the hole 3 formed in the glass plate 1 through the resin film 11 and the rubber plate 13, the surface of the hard glass plate 1 is rotated. When the diamond drill 2 that is driven to rotate contacts the surface 5 of the hard glass plate 1 by preventing the resin-based film 11 from shaking the diamond drill 2 when the diamond drill 2 contacts the surface 5. The possibility of chipping in the peripheral edge 31 of the hole 3 formed in the plate 1 can be eliminated, and the chip 32 generated in the hole 3 being formed is discharged through the resin film 11, whereby the chip 32 can eliminate the possibility of chipping in the peripheral edge 31 of the hole 3 formed in the glass plate 1, for example, using a diamond drill 2 having a small diameter, Even when the fine holes 3 are formed in the glass plate 1 for a display (PDP), a liquid crystal display (LCD) or the like, the probability that the peripheral edge 31 of the fine hole 3 formed in the glass plate 1 is chipped is the same as described above. Furthermore, since the rubber plate 13 for dressing is interposed between the glass plate 1 and the resin film 11, the resin film 11 made of synthetic resin is driven to rotate when the glass plate 1 is perforated. The clogging of the diamond drill 2 due to the chips 32 of the resin-based film 11 made of a synthetic resin that can occur when the diamond drill 2 is ground can be removed by dressing the diamond drill 2 with the rubber plate 13. The dressing mentioned above and below will mean the process of exposing the cutting edge on the grinding surface of the diamond drill 2.

  Moreover, it replaces with the above-mentioned, and the diamond drill 2 rotationally driven with respect to the glass plate 1 in which the resin-type film 11 made from a synthetic resin was affixed in the site | part 14 which should form the hole 3 in the one surface 5 is used for the said glass. In the Z direction intersecting one surface 5 of the plate 1, the hole 3 in the one surface 5 of the glass plate 1 is moved relatively toward the portion 14 where the hole 3 is to be formed, and the hole 3 is formed in the portion 14, After the hole 3 is formed, the diamond drill 2 is moved in the direction opposite to the above movement, and the diamond drill 2 is extracted from the hole 3 formed in the glass plate 1, and a rubber plate 13 for dressing the diamond drill 2 is separately prepared. After the hole forming step, the diamond drill 2 is moved relative to the prepared rubber plate 13 to place the diamond drill 2 on the rubber plate 13 and arranged. Unpleasant Mondo drill 2 may be in the Z direction crossing one surface of the rubber plate 13 is moved toward to the rubber plate 13 to dress the diamond drill 2. According to such a method for drilling a glass plate, the resin-based film 11 causes a vibration of the diamond drill 2 with respect to the rotational axis 22 when the diamond drill 2 to be rotated contacts the surface 5 of the hard glass plate 1. By preventing the diamond drill 2 that is rotationally driven from coming into contact with the surface 5 of the hard glass plate 1, it is possible to eliminate the possibility of chipping in the peripheral edge 31 of the hole 3 formed in the glass plate 1. The chip 32 generated in the inner hole 3 is discharged through the resin film 11, thereby eliminating the possibility of chipping in the peripheral edge 31 of the hole 3 formed in the glass plate 1 by the chip 32. When a fine hole 3 is formed in a glass plate 1 for a plasma display (PDP), a liquid crystal display (LCD), etc. using a diamond drill 2 having a small diameter , The probability of chipping of the peripheral edge 31 of the fine hole 3 formed in the glass plate 1 can be eliminated in the same manner as described above, and the rubber plate 13 for dressing the diamond drill 2 is separately prepared, and the hole forming step is completed. Later, the diamond drill 2 is moved relative to the prepared rubber plate 13 to place the diamond drill 2 on the rubber plate 13, and the arranged diamond drill 2 intersects one surface of the rubber plate 13. In order to dress the diamond drill 2 by moving it toward the rubber plate 13 in the Z direction, the eyes of the diamond drill 2 that can be generated when the synthetic resin-based film 11 is ground with the diamond drill 2 that is rotationally driven. The clogging can be removed by dressing the diamond drill 2 with the rubber plate 13.

  In the above example, the rubber plate 13 for dressing the diamond drill 2 is disposed between the resin film 11 and the one surface 5 of the glass plate 1. Instead of this, the rubber plate 13 and the glass plate are used. Alternatively, a resin film 11 may be provided between the one surface 5 and the hole 3 may be formed in the glass plate 1 in the same manner as described above.
