Description

  INDUSTRIAL APPLICABILITY The present invention is used for a glass plate peeling apparatus for peeling a glass plate that is closely adhered to a substrate or laminated at an extremely narrow interval, for example, a glass plate when forming a transfer type black matrix for a color filter using a glass plate, and a color filter The present invention relates to an apparatus for separating a glass substrate.

  As a method for forming a black matrix of a color filter substrate, there are many photolithography methods.

  In order to reduce the cost of the black matrix formation process in the color filter manufacturing process, there is a method that replaces the conventional photolithography method. This is a method of transferring a black matrix to a color filter glass substrate using a glass plate, as in Patent Document 1. Technology.

  This is a method of forming a black matrix for a color filter using a glass intaglio, and a black matrix material and an adhesive are placed on the intaglio and the adhesive and the black matrix material are transferred to a glass substrate for a color filter. After the transfer, the glass intaglio must be peeled off from the glass substrate provided with the color filter. However, when peeling off, since the glass plate has almost no elastic region, it can only be bent and peeled off little by little, or peeled off at once.

The patent literature is as follows.
Japanese Patent Laid-Open No. 5-66305

  However, it cannot be peeled at a time due to the influence of atmospheric pressure, and there is a limit to peeling using slight bending. Particularly when an adhesive is used, it is extremely difficult.

  If the substrate is a small plate and the glass plate is also small, it peels off almost without being affected by atmospheric pressure. However, if the size exceeds 300 mm square, peeling using bending becomes difficult.

  In order to solve the above problems, the present invention provides a glass plate peeling apparatus for peeling a glass plate in close contact with a substrate from the substrate in the invention of claim 1. Glass plate peeling having a mechanism, a wedge-shaped peeling start auxiliary mechanism provided on the peeling start side of the substrate and the glass plate, and a blower mechanism that is located at least on the peeling start side and blows air to the gap between the substrate and the glass plate A device is provided.

  Moreover, in invention of Claim 2, the said ventilation mechanism provides the glass plate peeling apparatus of Claim 1 provided also in the side of a glass plate.

  Moreover, in invention of Claim 3, the said ventilation mechanism provides the glass plate peeling apparatus of Claim 1 or 2 provided so that a movement in the peeling direction was possible.

  Moreover, in invention of Claim 4, the said board | substrate is a glass plate, The glass plate peeling apparatus in any one of Claims 1-3 is provided.

  Conventionally, peeling that is difficult to peel off with a glass plate has become possible.

  For example, a black matrix for a color filter has been formed by a photolithography method. However, when this method is realized, a black matrix can be formed using a glass substrate, and a cost reduction of about 30% is achieved. .

  Hereinafter, for example, a glass plate used for forming a transfer type black matrix for a color filter using a glass plate and a glass substrate used for a color filter are closely adhered to each other or laminated at an extremely narrow interval when used as an apparatus for separating the glass substrate. An embodiment of the present invention will be described in detail with reference to the drawings, using an example when applied to a glass plate peeling apparatus for peeling a glass plate.

  Usually, in order to separate and peel two closely bonded or pressure-bonded glasses, the better the adhesion, the less air there is between the two glass plates, so the glass plates are mechanically supported and peeled off. It is difficult.

  If it is to be peeled off, it must be peeled off slowly and then slowly as the air naturally flows into the gap. If you try to force it off, the glass plate will be damaged.

  Therefore, the peeling device of this method makes the flow of air with high-pressure air or the like, and blows it between two pieces of glass to eliminate the vacuum state between the glasses, and the air surface of the glass surface Swelling causes the glass to bend slightly and separates the two pieces of glass.

  As a form of the apparatus, the glass plate and the two glass substrates that are in close contact with each other are fixed from the back surface of the glass substrate so as not to move by a method such as vacuum suction. In order to allow air to enter easily, a wedge-shaped blade is used to divide the gap between the two sheets on the side of the glass substrate or two adjacent corners to create a gap. The following peeling is started from this side or a side between the corners.

  An air nozzle is mounted so as to be movable along the outer periphery of the glass substrate, and separated and moved while blowing air.

  In addition, when a large glass is used, the air pressure does not reach far, so the upper surfaces of the combined glass plates are sucked by vacuum suction, and the separated glass is lifted so that it can be separated.

  Several adsorbing places on the upper surface are arranged evenly on this side so that they can be lifted up and lifted from the vicinity of the two adjacent sides with the separation of the two glass corners described above.

  When the one side is separated almost evenly by the high-pressure air, the one side of the glass is slightly lifted by the suction pad supporting the upper glass plate.

  The air nozzle that separates one side sandwiched between two adjacent corners is supported by a guide mounted in parallel outside the two sides perpendicular to this, and between the two separated glasses. You can go around.

  In this way, high-pressure air is blown to start peeling from one end of the upper glass, and an air nozzle is inserted into the gap between the peeled glass to further peel off and lift the one end of the upper glass. Peel and separate.

  FIG. 1 and FIG. 2 are diagrams of an apparatus for actually peeling two pieces of glass having a thickness of 360 mm × 460 mm × 0.7 mm.

  In addition, a layer with a black matrix of 0.7 μm is partially provided between the two sheets, and an adhesive is provided in another part of the area. It is in a state.

  (1) indicated by diagonal lines is a lower frame formed by two bonded glass plates (360 mm × 460 mm) to be peeled and (2) which is assembled with a frame for placing it. (3) is an upper frame for lifting the peeled upper glass plate. The upper frame (3) can be rotated in the direction of the arrow (A) by a hinge (4) attached to the lower frame (2).

  Vacuum pads (5) and (6) are attached to four positions of the lower frame (2), and after the glass plate (1) is mounted, the vacuum pads (5) and (6) are sucked and fixed to the lower frame (2). Similarly, a vacuum pad (7) is attached to the upper frame (3) to fix the upper surface of the glass plate (1). The vacuum pad (7) can be slid in the direction of the arrow (B) by the linear guide (8), and the pad neck can swing freely.

  The two bonded glass plates (1) set on the lower frame (2) are fixed on the upper surface and the lower surface as described above, and then, from the two corners by the cutter blades (9) and (10). Separated from the seam of the two glasses.

  First, air nozzles (17) and (18) attached to the cutter blades (9) and (10) blow high-pressure air to the separated corners to increase the separation area of the corners. Next, the separation area is expanded by the air nozzle (11). In addition, the air nozzles (13) and (14) mounted on the side perpendicular to the side also move the side perpendicular to the side on which the air nozzle (11) is mounted while being separated by air.

  Thus, when the glass separation area is increased to some extent, the upper frame (3) is lifted together with the upper glass, and the gap is slightly widened. While being supported by the slide guides (15) and (16) and moving in the gap, the air nozzle (11) is swallowed to blow air and further increase the peeling area.

  Finally, as shown in FIG. 3, the upper glass (22) is absorbed by the structure of the vacuum pad (7), and the upper glass (22) and the lower glass (21) can be separated in the bent state. .

It is an external appearance top view of a peeling apparatus. It is a peeling apparatus external appearance side view. It is a side view which shows the bending state of glass.
