　本発明は、カッタホイールとガラス板とを、または、カッタホイールを平面座標系において輪郭線移動させながらカッタホイールを上記平面座標系に直交する軸線の回りに角度制御して上記カッタホイールの刃面を、常に上記輪郭線の法線方向に向けて移動させ、ガラス板にスクライブを行うスクライブ装置であって、上記カッタホイールを、上記法線方向においてガラス板面に対して傾斜させた姿勢で、閉曲線の矩形、楕円形等の輪郭線をスクライブすると、スクライブ線の全周に渡って、そのスクライブ線下に、ガラス板の厚み方向において、上記カッタホイールの傾斜角度に沿って傾斜したスクライブ溝が形成される。 The present invention relates to the blade surface of the cutter wheel by controlling the angle of the cutter wheel and the glass plate or by controlling the angle of the cutter wheel around an axis perpendicular to the planar coordinate system while moving the contour line of the cutter wheel in the planar coordinate system. Is a scribing device that always moves toward the normal direction of the contour line and scribes the glass plate, and the cutter wheel is inclined with respect to the glass plate surface in the normal direction, When scribing a contour line such as a closed curve rectangle or ellipse, a scribe groove inclined along the inclination angle of the cutter wheel in the thickness direction of the glass plate is formed under the scribe line over the entire circumference of the scribe line. It is formed.
　次に、上記ガラス板に曲げ応力となる圧力プッシュ衝撃等の方法により、スクライブ溝をガラス板下面まで進展させることにより、スクライブ線下に抜き勾配が形成される。すると、スクライブ線の内側領域を外側領域に対して持上げるか、外側領域を内側領域に対して持上げることにより、内側領域と外側領域とを簡単に分断できる。即ち、製品である外側領域ガラス板に矩形、楕円形等の開口部を簡単に形成することができる。 Next, a draft is formed under the scribe line by advancing the scribe groove to the lower surface of the glass plate by a method such as pressure push impact which becomes a bending stress on the glass plate. Then, the inner region and the outer region can be easily divided by lifting the inner region of the scribe line with respect to the outer region or lifting the outer region with respect to the inner region. That is, an opening such as a rectangle or an ellipse can be easily formed in the outer region glass plate as a product.
　スクライブ線の内側領域側に傾斜したカッタホイールにより閉曲線の矩形、楕円形等の輪郭線をスクライブすると、スクライブ線の全周に渡って、そのスクライブ線下に、ガラス板の厚み方向において、外側領域側に傾斜したスクライブ溝が形成される。 When scribing a contour line such as a rectangle or ellipse with a closed curve with a cutter wheel inclined toward the inner area side of the scribe line, the outer area in the thickness direction of the glass plate is placed under the scribe line over the entire circumference of the scribe line. A scribe groove inclined to the side is formed.
　次に、上記ガラス板に曲げ応力となる圧力プッシュ衝撃等の方法により、スクライブ線をガラス板下面まで進展させることにより、スクライブ線の内側領域を押えた状態で、同スクライブ線の外側領域を吸着して持上げることにより、製品である外側領域のガラス板に開口部を形成することができる。 Next, by adhering the outer area of the scribe line while holding the inner area of the scribe line by advancing the scribe line to the lower surface of the glass sheet by a method such as pressure push impact that becomes a bending stress on the glass plate. Then, the opening can be formed in the glass plate in the outer region that is the product.
　また、逆に、スクライブ線の外側領域側に傾斜したカッタホイールにより閉曲線の矩形、楕円形等の輪郭線をスクライブすると、スクライブ線の全周に渡って、そのスクライブ線下に、ガラス板の厚み方向において、内側領域側に傾斜したスクライブ溝が形成される。 Conversely, when a contour line such as a closed curve rectangle or ellipse is scribed by a cutter wheel inclined to the outer region side of the scribe line, the thickness of the glass plate is placed under the scribe line over the entire circumference of the scribe line. In the direction, a scribe groove inclined toward the inner region is formed.
　次に、上記ガラス板に曲げ応力となる圧力プッシュ衝撃等の方法により、スクライブ線をガラス板下面まで進展させることにより、スクライブ線の外側領域を押えた状態で、同スクライブ線の内側領域を吸着して持上げることにより、製品である外側領域のガラス板に開口部が形成される。 Next, by adhering the inner area of the scribe line while holding the outer area of the scribe line by advancing the scribe line to the lower surface of the glass sheet by a method such as pressure push impact that becomes a bending stress on the glass plate. As a result, an opening is formed in the glass plate in the outer region that is the product.
　下端にカッタホイールを備えたスクライブヘッドは、上面にガラス板を支持してＹ軸移動するスクライブテーブルのはるか上方において、Ｘ軸移動する軸受装置に、軸線が上記ガラス板面に直交して保持され、角度制御され回動をする回転軸の直下において、該回転軸にブラケットを介して取付けられているため、回転軸の軸線上にカッタホイールを合せてスクライブヘッドの傾斜取付けができる。また、回転軸の下端とスクライブテーブル上のガラス板との高さ距離が十分に確保されているため、スクライブヘッドをガラス板面に対して角度変更自在に傾斜取付けできる。さらに、スクライブ線の内側領域の側に向って傾斜させるか、外側領域の側に向って傾斜させるか自由に傾斜取付けできる。従って、スクライブヘッドの下端に備えたカッタホイールのガラス板面に対する傾斜角度の変更、調節、また傾斜方向の変換が簡単に行える。また、上記の如く、回転軸の下端とガラス板面との高さ距離が確保されているため、縦長のスクライブヘッドを取付けることができ、カッタホイールを傾斜方向に沿ってガラス板面に直線押圧でき、スクライブ溝を精確に形成できる。 A scribing head with a cutter wheel at the lower end is supported by a bearing device that moves in the X-axis so that the axis is orthogonal to the glass plate surface, far above the scribe table that supports the glass plate on the upper surface and moves in the Y-axis. Since the angle-controlled rotating shaft is mounted directly below the rotating shaft via a bracket, the scribe head can be mounted at an inclination by aligning the cutter wheel on the axis of the rotating shaft. In addition, since the height distance between the lower end of the rotating shaft and the glass plate on the scribe table is sufficiently secured, the scribe head can be inclined and attached to the glass plate surface so that the angle can be changed. Further, it can be tilted toward the inner region side of the scribe line, inclined toward the outer region side, or can be freely tilted. Therefore, it is possible to easily change and adjust the inclination angle of the cutter wheel provided at the lower end of the scribe head, to adjust the inclination direction, and to change the inclination direction. In addition, as described above, since the height distance between the lower end of the rotating shaft and the glass plate surface is secured, a vertically long scribe head can be attached, and the cutter wheel is linearly pressed against the glass plate surface along the tilt direction. And scribe grooves can be accurately formed.
　本発明によれば、カッタホイールを傾斜させてセットし、閉曲線である矩形、楕円形等異形をスクライブし、そのスクライブ線の全周に渡って、スクライブ線下に、ガラス板の厚み方向に向って傾斜したスクライブ溝を形成するガラス板のスクライブ装置を提供することができる。 According to the present invention, the cutter wheel is tilted and set, and a closed curve such as a rectangle or an ellipse is scribed, and the entire circumference of the scribe line is placed below the scribe line in the thickness direction of the glass plate. It is possible to provide a scribing device for a glass plate that forms a scribe groove that is inclined.
