Description

玻璃面板支撑装置及玻璃面板减薄设备 技术领域
本发明的实施例涉及一种玻璃面板支撑装置及玻璃面板减薄设备。
背景技术
目前, 液晶显示器的发展趋势向着薄型化和轻型化的方向发展, 为了适 应这种发展趋势, 单片玻璃面板的厚度也逐渐变薄, 从 0.7毫米(mm, 也可 表示为 t ) 、 0.63mm逐渐减薄为 0.5mm、 0.4mm甚至 0.3mm以下。
从生产制造工艺考虑玻璃面板减薄主要有以下两种途径: 第一种是直接 制造薄型玻璃面板, 该方法产工艺复杂, 且需要对现有的生产线进行升级, 花费巨大; 第二种方法是利用已有的生产线系统生产玻璃基板后对产品进行 减薄处理, 以得到目标厚度的薄型玻璃面板。
目前大多釆用第二种方法处理, 其中, 减薄处理分为物理研磨减薄和化 学蚀刻减薄两种技术。 主流的减薄工艺为以化学蚀刻为主, 以物理研磨抛光 为辅。 其中, 蚀刻工艺是应用氢氟酸(HF )与二氧化硅(Si02 )发生反应并 使其溶解生成四氟化硅的原理达到减薄的目的, 其化学反应式为:
6HF+ Si02=¾SiF6+2¾0。
玻璃面板在进行蚀刻时有喷洒式和浸泡式两种, 目前多釆用多片直立喷 洒式, 如附图 la和附图 lb所示分别为玻璃支撑装置的正视图和侧视图, 多 片玻璃面板 103并排摆放于支撑架 104上, 刻蚀液 102从顶部的喷淋装置的 刻蚀液喷淋头 101中喷出后, 与支撑架中的玻璃接触并反应。
但是, 由于玻璃面板 103是固定于支撑架 104上, 且支撑架 104是固定 于小车 105中, 因此, 刻蚀液首先与玻璃面板的上半部分接触并反应, 然后 再与玻璃面板的下半部分接触并反应, 从刻蚀液的浓度上来讲, 玻璃面板的 下半部分的刻蚀液的浓度要明显低于上半部分, 从反应时长上来讲, 玻璃面 板的下半部分的反应时长要明显小于上半部分, 所以造成刻蚀后的玻璃面板 下半部分的厚度要大于上半部分, 厚度差能够达到 ± 15微米。 发明内容
本发明的实施例提供了一种玻璃面板支撑装置及玻璃面板减薄设备, 在 进行玻璃面板减薄处理时使用, 能够使得刻蚀液能够均匀分布于玻璃面板表 面, 保证减薄处理后的玻璃面板厚度均匀。
本发明一方面提供了

所述至少一个支撑架与所述转动部固定连接, 所述转动部带动所述支撑 架及固定于所述支撑架上的玻璃面板转动。
本发明另一方面还提供了一种玻璃面板减薄设备, 所述减薄设备包括上 述的玻璃面板支撑装置。
本发明实施例提供的支撑装置将固定玻璃面板的支撑架固定于转动部 上, 在将该支撑装置用于玻璃面板减薄处理时, 固定于支撑架中的玻璃面板 能够在转动部的带动下转动, 从而使得喷洒的刻蚀液能够均匀分布于玻璃面 板上, 从而能够使得减薄处理后的玻璃面板厚度均匀。 附图说明

其中, 转动轴 702上固定的支撑架 701的数量根据生产需要确定, 图 7 中仅以转动轴 702上固定 4个支撑架为例, 并不用于限定本发明。 图 7所示 的刻蚀液喷淋头 101从玻璃面板支撑装置的上方喷洒刻蚀液 102, 位于其下 方的玻璃面板支撑装置中的转动轴转动带动固定于支撑架中的玻璃面板绕转 动轴转动, 使得刻蚀液可以均匀喷洒于各玻璃面板表面, 保证了刻蚀后的玻 璃面板厚度均匀。
其中, 在转动轴上固定支撑架时, 只要并行固定的每组支撑架之间保持 一定的角度, 即可保证刻蚀液均勾喷洒在玻璃面板上。
