    • Methods for separating glass sheets from glass ribbons are disclosed. One method includes forming a glass ribbon having a curvature in a lateral direction. A conformable nosing is engaged with a first surface of the glass ribbon such that the conformable nosing conforms to the curvature of the glass ribbon. The glass ribbon is scored along a scoring line on a second surface of the glass ribbon. The conformable nosing is then at least partially disengaged from the first surface of the glass ribbon by adjusting a bow of the conformable nosing. A bending moment is applied to the glass ribbon to separate a glass sheet from the glass ribbon at the scoring line. Application of the bending moment conforms the curvature of the glass ribbon to the bow of the conformable nosing prior to the glass sheet separating from the glass ribbon.
    • 公开了从玻璃带分离玻璃板的方法。 一种方法包括在横向上形成具有曲率的玻璃带。 与玻璃带的第一表面接合,使得适形的配合符合玻璃带的曲率。 玻璃带沿着玻璃带的第二表面上的刻痕线刻划。 然后,通过调节适形鼻孔的弓形,至少部分地从玻璃带的第一表面脱离适形的鼻子。 弯曲力矩施加到玻璃带上,以在刻痕线上将玻璃板与玻璃带分离。 在玻璃板与玻璃带分离之前,弯曲力矩的应用将玻璃带的曲率符合到适形鼻孔的弓形。

    • Methods of using a laser to separate a glass sheet is presented that employs an elongated and, preferably, asymmetrically-truncated laser beam. The methods allow glass sheets suitable for use in modern display applications to be separated at speeds up to about 200 mm/s with low levels of residual stress, e.g., levels of residual stress which are less than or equal to 100 psi, and preferably less than 50 psi. Glasses with high coefficients of thermal expansion (e.g. greater than about 35×10−7/° C.) maybe separated at faster speeds. Such low levels of residual stress translate into low levels of distortion during the manufacture of display panels (e.g., LCD panels) as well as in improved properties (geometry, strength, defect-free etc.) of the separated edges. The methods can be used with glasses of various types including glasses having high coefficients of thermal expansion and also with glass sheets of different thickness.
    • 提出了使用激光器分离玻璃板的方法,其采用细长的,优选地,非对称截断的激光束。 这些方法允许适用于现代显示应用的玻璃板以高达约200mm / s的速度分离,具有低水平的残余应力,例如小于或等于100psi的残余应力水平,优选较小 超过50psi。 具有高热膨胀系数(例如大于约35×10 -7 /℃)的玻璃杯可能以更快的速度分离。 残余应力的这种低水平在显示面板(例如,LCD面板)的制造期间以及改进的分离边缘的性质(几何形状,强度,无缺陷等)转化为低水平的变形。 该方法可用于各种类型的玻璃,包括具有高热膨胀系数的玻璃以及不同厚度的玻璃板。

    • Experimental data is presented which shows that laser scoring of glass sheets (112) with existing techniques produces unacceptable levels of residual stress in the separated sheets as the scoring speed is increased. Methods for solving this problem are disclosed which employ elongated and, preferably, asymmetrically-truncated laser beams (13). The methods allow glass sheets (112) to be scored at speeds of 1000 mm/s and above with low levels of residual stress, e.g., levels of residual stress which are less than or equal to 500 psi. Such low levels of residual stress translate into low levels of distortion during the manufacture of display panels (e.g., LCD panels) as well as in improved properties of the separated edges. The methods can be used with glasses of various types including glasses having low coefficients of thermal expansion.
    • 实验数据显示,现有技术的玻璃板(112)的激光刻痕在分选片材中随着刻痕速度的提高而产生不可接受的残余应力水平。 公开了解决这个问题的方法,其采用细长的,优选的是非对称截断的激光束(13)。 该方法允许玻璃板(112)以低于或等于1000mm / s的速度以低水平的残余应力(例如残余应力的水平小于或等于500psi)进行刻痕。 这种低水平的残余应力在显示面板(例如LCD面板)的制造过程中转化为低水平的变形以及分离边缘的改进的性质。 该方法可用于各种类型的眼镜,包括具有低热膨胀系数的眼镜。
