在本较佳实施例中， 所述待磨边玻璃基板 6固定于平台 8后与水平方 向所成的角度为 10。-60。， 优选为 30。， 可以使得从防尘隔板 2导入的冷却 水由于重力而自动流向砥石 4加工处， 进而润湿砥石 4, 并进一步冲走磨 边时产生的颗粒。
步骤 103、 从防尘隔板 2 中导入冷却水 9, 所述冷却水 9在第一缝隙
28处形成水帘， 并沿着待磨边玻璃基板 6流向砥石加工 4处；
在本较佳实施例中， 所述防尘隔板 2 包括： 第一、 第二及第三防尘隔 板 22、 24及 26, 所述第一、 第二、 第三防尘隔板 22、 24、 26并排设置， 所述第一、 第二防尘隔板 22、 24之间及第二、 第三防尘隔板 24、 26之间 分别形成第二缝隙 29 及第三缝隙 30。 所述第一、 第二及第三防尘隔板 22、 24及 26与待磨边玻璃基板 6形成的第一缝隙 28均为 0.5-2mm, 优选 为 lmm。 所述冷却水 9分别沿着第二缝隙 29、 第三缝隙 30及第三防尘隔 板 26上表面流下来， 并在第一、 第二、 第三防尘隔板 22、 24、 26下端形 成水帘， 从而形成三段式流出结构， 更好地堵死研磨时产生的颗粒进入非 研磨区 20的通道。
步骤 104、 导通吹气管形成一风帘区域 7, 将待磨边玻璃基板 6 边缘 处的研磨剩水吹落；
在实际研磨过程中， 待磨边玻璃基板 6会发生旋转， 若待磨边玻璃基 板 6边缘有研磨后的剩水， 其内的颗粒会因为待磨边玻璃基板 6的旋转随 着剩水滑入待磨边玻璃基板 6 的图案区域， 进而损伤待磨边玻璃基板 6。 针对上述情况， 把吹气管设于砥石 4前方， 从而在砥石 4前方形成一个风 帘区域 7 , 所述吹气管吹出高气压 （CDA ) 气体， 进而把依附在待磨边玻 璃基板 6边缘的带有颗粒的剩水吹落， 保证颗粒不会随着剩水滑入待磨边 玻璃基板 6图案区域。
步骤 105、 启动砥石 4, 进行研磨， 完成研磨加工， 在此过程中， 研 磨产生的颗粒被水帘及防尘隔板 2挡住， 防止其掉落到待磨边玻璃基板 6 上， 同时吹气管形成一风帘区域 7将待磨边玻璃基板 6边缘处的研磨剩水 吹落。
在本发明中通过防尘隔板 2及水帘挡住研磨时产生的颗粒， 并用吹气 管把待研磨玻璃基板 6边缘的带有颗粒的剩水吹落， 从而在研磨过程中很 好地保护待研磨玻璃基板 6上的图案， 以免被刮伤。
综上所述， 本发明提供一种玻璃基板磨边机的防尘方法， 通过在平台 的研磨区与非研磨区之间设置防尘隔板及水帘， 从而把研磨区与非研磨区 隔开， 并在砥石前方设置一吹气管， 从而把依附在待磨边玻璃基板边缘的 带有颗粒的剩水吹落， 防止该剩水滑入待磨边玻璃基板图案区域， 从而能 够很好地防止待磨边玻璃基板磨边时产生的颗粒掉落到玻璃基板上， 刮伤 待磨边玻璃基板上的图案， 确保了研磨出来的玻璃基板的品质。
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。
