一种TFT玻璃基板研磨烧边的判定方法
摘要：
本发明公开了一种TFT玻璃基板研磨烧边的判定方法，包括如下步骤：S11：启动TFT玻璃基板研磨装置；S12：变频器控制主轴电机带动研磨轮旋转；S13：检测电机电流；S14：根据正常磨边时电机电流设定一个烧边电流判定值；S15：将检测到的电机电流与烧边电流判定值进行比较，如果检测到的电机电流小于或等于烧边电流判定值，则判定为TFT玻璃基板正常研磨，如果检测到的电机电流大于烧边电流判定值，则判定为TFT玻璃基板烧边；S16：如果TFT玻璃基板研磨正常，则对研磨后的TFT玻璃基板进行清洗，如果TFT玻璃基板烧边，则将烧边的TFT玻璃基板传送到就近的抽检工位抽出，避免了对烧边玻璃的清洗，提高生产效率。
摘要（英）：

The invention discloses a judgment method for grinding edge burning of a TFT glass substrate. The method includes the following steps that S11, a TFT glass substrate grinding device is started; S12, a frequency converter controls a main shaft motor to drive a grinding wheel to rotate; S13, the motor current is detected; S14, an edge burning current judgment value is set according to the motor current generated during normal edge grinding; S15, the detected motor current is compared with the edge burning current judgment value, if the detected motor current is smaller than or equal to the edge burning current judgment value, it is judged that grinding of the TFT glass substrate is normal, and if the detected motor current is larger than the edge burning current judgment value, it is judged that the TFT glass substrate is in edge burning; and S16, if grinding of the TFT glass substrate is normal, the ground TFT glass substrate is cleaned, and if the TFT glass substrate is in edge burning, the edge-burnt TFT glass substrate is transferred to a nearby spot check station to be drawn out, cleaning of edge-burnt glass is avoided, and the production efficiency is improved.
