请参阅图 5 (图中箭头方向表示各部件的移动方向）和图 6, 在本实 施例中， 玻璃基板 40朝向研磨装置的研磨砥石 24进行运输， 玻璃基板 40 的研磨区域 402 与研磨装置的研磨砥石 24 相接触后， 第一与第二挡板 26、 28 分别朝向玻璃基板 40 移动， 至图 6 所示位置， 第一与第二挡板 26、 28的第一与第二緩冲体 262、 282分别抵靠于玻璃基板 40的上表面及 下表面。 在本实施例中， 所述第一与第二挡板 26、 28 的移动相对独立， 优选的， 所述第二挡板 28的移动上限为与玻璃基板 40的下表面相平齐， 而通过第一挡板 26的移动来适用不同厚度的玻璃基板 40。
步骤 4、 进行磨边操作。
所述步骤 4包括： 喷水汽， 然后转动研磨砥石 24研磨玻璃基板 40, 同时排出水汽与研磨时产生的碎屑。
请参阅图 7 , 步骤 4中研磨装置的研磨砥石 24对玻璃基板 40的研磨 区域 402进行研磨时， 可使用喷汽装置 27向玻璃基板 40研磨区域 402上 下表面喷洒水汽， 该水汽冲洗玻璃基板 40 的同时还起到冷却作用， 以避 免研磨装置的研磨砥石 24与玻璃基板 40之间的摩擦产生的热量导致玻璃 基板 40的变形， 同时使用排汽装置 29 , 用于将喷汽装置 27喷洒的水汽及 研磨装置的研磨砥石 24研磨产生的玻璃碎屑排出， 进而对玻璃基板 40的 研磨区域 402进行清理。
该喷汽装置 27可设于第一、 第二挡板 26、 28与研磨装置的研磨砥石 24之间 , 而排汽装置 29可设于研磨装置的研磨砥石 24的后方。 研磨时， 喷汽装置 27及排汽装置 29可配合第一与第二挡板 26、 28使用进一步清 理剥离碎屑。
当然， 步骤 4 完成之后， 移动第一与第二档板 26、 28 离开玻璃基板 40, 然后搬运玻璃基板 40离开该研磨工位。
综上所述， 本发明的显示面板的玻璃基板磨边方法， 通过在玻璃基板 研磨区域与非研磨区域之间设置挡板， 研磨过程中挡板对玻璃基板进行防 尘， 有效避免研磨装置在对玻璃基板的研磨区域进行研磨时所产生的玻璃 屑飞溅到玻璃基板的非研磨区域， 进而有效保护非研磨区域表面， 避免了 由于玻璃基板非研磨区域表面损伤对后续制程产生的影响， 大幅度降低了 成本， 同时， 由于在挡板朝向玻璃基板的端面设置緩冲体， 有效緩冲玻璃 基板与研磨装置之间摩擦所产生的震动， 大幅度降低该震动对玻璃基板所 造成的损坏。
以上所述， 对于本领域的普通技术人员来说， 可以根据本发明的技术 方案和技术构思作出其他各种相应的改变和变形， 而所有这些改变和变形 都应属于本发明权利要求的保护范围。
