Definitions
- the present invention relates to an improvement in a technique for cleaving a glass film by local heating along a planned cutting line in the glass film and thermal stress generated with cooling of the heating region.
- a flat panel display represented by a liquid crystal display, a plasma display, an organic EL display and the like has become the mainstream as a video display device in recent years. Since the weight reduction of these FPDs is promoted, the glass substrate used for the FPD is currently being made thin (glass film).
- organic EL is being used as a flat light source such as a light source for indoor lighting by causing only three colors (for example, white) to emit light without causing the three primary colors to be flickered by TFT as in a display.
- the organic EL lighting device can freely deform the light emitting surface if the glass substrate is flexible, the glass substrate used in the lighting device also has sufficient flexibility. In view of this, a significant reduction in thickness is being promoted.
- a thin glass plate such as a glass film is also used to reduce the weight of window glass by bonding it to both surfaces of an organic resin transparent plate.
- glass films used in various fields are cut into a predetermined size according to the product size.
- a method is adopted in which the glass film is locally heated and cooled, and the initial crack formed in the glass film is advanced and cleaved by the thermal stress generated at that time (for example, see Patent Document 2). ).
- the glass film is locally heated by irradiating a laser along a planned cutting line of the glass film. Later, the heated area is locally cooled by a cooling device. Thereby, while producing a thermal stress in a glass film, the initial stage crack previously formed in the front-end
- the glass plate is blown and floated from below so that the back surface of the glass plate is not in contact with the processing table or the like. It is conceivable to apply thermal stress along the planned cutting line of the glass plate.
- JP-A-6-915 Japanese Patent Laid-Open No. 2003-034545 JP 2007-246298 A
- Patent Document 3 if the technique of levitating a glass plate with gas at the time of cleaving is applied to a thin glass film, the following problem newly arises.
- the glass film is rich in flexibility as it is thinned, but is easily damaged. Therefore, as shown in FIG. 6, when a gas is blown directly onto the glass film G from below, as the cleaving operation progresses, the glass film G rises from the gap between the cleaved surfaces of the individual glass films Ga after the cleaving is completed.
- the glass film Ga flutters greatly while the glass film Ga flutters due to the gas leaked into the glass (arrow A in the figure). Therefore, the cleaved end faces of the glass film Ga adjacent to each other in the width direction rub against each other, and the cleaved end face of the glass film Ga has a defect that causes breakage such as chipping or cracking. There is a risk of cleaving defects such as.
- an object of the present invention is to efficiently cleave a glass film with thermal stress without causing cleaving defects.
- the glass film cleaving method according to the present invention which was created to solve the above-mentioned problems, is the thermal stress generated in the glass film by local heating along the planned cutting line intersecting the width direction of the glass film and cooling of the heating region.
- the initial crack formed at the tip of the cleaving line is advanced along the cleaving line, and the glass film is cleaved.
- the glass film is cleaved in a state where it is lifted and supported while covering the cleaved portion including the cleaved planned line of the glass film from below with the floated resin sheet. .
- the glass film is lifted and supported by the resin sheet levitated by the gas at the time of cutting. And in this state, the cleaving part including the cleaving line of the glass film is covered from below by the resin sheet. Even if the glass sheet is cleaved using thermal stress, the resin sheet is not cut by local heating with a laser or the like, so the sprayed gas is blocked by the resin sheet and flows into the gaps between the cut surfaces of the glass film. There is no. As a result, the broken glass glass does not vibrate greatly while fluttering due to the blown gas, so that the attitude of the glass film is also stabilized.
- the resin sheet is more flexible than the glass sheet.
- the resin sheet may be wider than the glass film, and may protrude to both outer sides in the width direction of the glass film.
- the entire width direction of the lower surface of the glass film is surely covered with the resin sheet. Therefore, when the glass film is cleaved by thermal stress, it is possible to more reliably prevent the gas blown to the resin sheet from flowing into the gaps between the cut sections of the glass film.
- the glass film is curved in the width direction by lifting and supporting the resin sheet, and a non-floating region that is not lifted and supported by the resin sheet is formed in a region excluding the cleaved portion of the glass film. Good.
- the glass film may be curved in the width direction, and a non-floating region that is not lifted and supported by the resin sheet may be formed in a part of the width direction of the glass film. If it does in this way, since the weight of the glass film which must be lifted and supported by the resin sheet is reduced, even if the weight of the glass film is increased, the cleaving operation can be continued without any problem.
- the ears are preferably included in the non-floating region.
- the ear portion is relatively thicker than the center portion (effective portion) in the width direction that can be a product, and the weight per unit length in the width direction is increased. Therefore, the attitude
- the resin sheet will move with the glass film, so it will rub between the glass film and the resin sheet. Therefore, the ratio of scratches caused by rubbing on the lower surface of the glass film, that is, the contact surface of the glass film with the resin sheet, can be reliably reduced.
- the resin sheet is floated by gas at a fixed position, and only the glass film is slid on the resin sheet. You may make it send.
- the resin sheet is preferably formed of a foamed resin.
- the resin sheet has innumerable cavities derived from the foamed resin, the air present in the cavities serves as a heat insulating material. Therefore, the amount of heat generated by local heating or cooling applied to the glass film at the time of cleaving becomes difficult to be radiated to the resin sheet side. Therefore, it is possible to efficiently apply a thermal stress to the glass film, and it is possible to improve the cleaving efficiency of the glass film.
- the local heating is preferably performed by a laser.
- the local heating of the glass film can be efficiently performed by the heat of laser irradiation.
- the laser a carbon dioxide laser is preferably used.
- the absorption wavelength of the glass can be made appropriate, and local heating can be easily performed in a stable state, and the cost is low. It becomes.

Therefore, if the glass film which passed through such a cleaving process is wound up in a roll shape to produce a glass roll, a glass roll having high end face strength can be produced, which is extremely advantageous in practice.
- the supply source for example, a glass roll obtained by winding a glass film in a roll shape, a molding apparatus for continuously forming the glass film, or the like can be used.
- the glass film cleaving apparatus according to the present invention which was created to solve the above-described problems, is the above-mentioned cleaving due to local heating along the planned cutting line intersecting the width direction of the glass film and the thermal stress generated by cooling of the heating region.
- the initial crack formed at the tip of the planned line is advanced along the cleaving planned line, and the resin sheet disposed in the cleaving region of the glass film and the resin
