可挠性薄玻璃之自由外型切割的方法及设备;METHODS AND APPARATUS FOR FREE-SHAPE CUTTING OF FLEXIBLE THIN GLASS

摘要

提供一种方法与设备用于支撑来源玻璃板以及界定至少部分非笔直的切割线，该切割线建立封闭图案，该封闭图案外切期望最终外型；使用机械刻划装置在起始线上刻划玻璃板；开始于起始线上施加雷射光束至玻璃板，并沿着切割线相对于玻璃板连续移动雷射光束，以提高切割线上的玻璃板的温度至实质一致的温度，其中该雷射光束为圆形；以及在施加雷射光束的同时，施加冷却流体，使得该冷却流体至少降低该玻璃板的温度，以沿着切割线于玻璃板中传播裂口。; scoring the glass sheet at an initiation line using a mechanical scoring device; applying a laser beam to the glass sheet starting at the initiation line and continuously moving the laser beam relative to the glass sheet along the cutting line to elevate a temperature of the glass sheet at the cutting line to a substantially consistent temperature, where the laser beam is of a circular shape; and applying a cooling fluid simultaneously with the application of the laser beam, such that the cooling fluid at least reduces the temperature of the glass sheet in order to propagate a fracture in the glass sheet along the cutting line.
