参见图 1 , 其为本发明全世代适用的真空贴合机一较佳实施例的模块 结构图。 本发明的全世代适用的真空贴合机, 可以在现有真空贴合机基础 上改进实现, 在机台 11上主要设置包括移载装置 12、 定位装置 13、 涂胶 装置 14、 翻转装置 15以及至少一个真空贴合装置 16, 其中, 所述机台 11 的尺寸足够大以适合于基板尺寸, 所述移载装置 12 具有可调节间距以适 合于基板尺寸的夹持头, 所述翻转装置 15 具有足够密的真空吸脚以适合 于基板尺寸, 所述定位装置 13 包括识别基板在机台上粗略位置的尺寸辨 识系统以及对基板进行精细对位的标记位置辨识系统。 本发明的全世代适用的真空贴合机在大尺寸机台的前提下, 使用尺寸 辨识系统确定基板尺寸, 定位基板所在位置, 然后使用标记进行精准对 位, 将 TFT基板与 CF基板对组在一起。
将机台做成 G10 甚至更大尺寸, 这一点与已有的真空贴合机设计不 同, 已有的真空贴合机机台与基板尺寸相适应, 本发明中使用大尺寸的机 台, 是为了让所有尺寸的基板都可以放在机台上进行贴合。
本发明的搬送基板的移载装置需要配合基板尺寸设计为可整式。 如图 2 所示, 其为本发明全世代适用的真空贴合机一较佳实施例的移载装置的 结构示意图, 移载装置 1 具有可调节间距的夹持头 2, 夹持头可按箭头方 向调节移动。 普通移载装置 (Robot )应可调整夹持头 (Fork ) 的间距, 便 于装载不同大小的基板; 真空移载装置的夹持头也应可调整夹持头间距, 便于装载翻转后不同尺寸的基板。
如图 3所示, 其为本发明全世代适用的真空贴合机一较佳实施例的吸 真空脚的结构示意图。 翻转装置应有较密的吸真空脚(Pin ) , 因为吸一片 基板需要多个吸真空脚的配合, 稀疏的吸真空脚无法满足小片基板的翻转 需求。 图 3 中吸真空脚 3的密度对于不同尺寸的基板 4、 5及 6分别为无 法满足、 刚好满足及完全满足的状态, 因此, 吸真空脚 3 的密度越大, 所 能支持的基板尺寸越小。 翻转装置还应可以控制吸真空脚的气流, 防止装 载大片基板时压力太小无法吸起, 或者是装载小片基板时气流力量过大造 成破片。
本发明全世代适用的真空贴合机具有尺寸辨识系统, 目的为识别基板 在机台上的粗略位置。 尺寸辨识系统具有预先编写的程序, 向使用者提供 工作界面。 如图 4所示, 其为本发明全世代适用的真空贴合机一较佳实施 例的尺寸辨识系统的工作过程示意图。 在尺寸辨识系统的工作过程, 控制 屏幕上所显示的工作界面中, 包括机台的模拟界面 7 , 基板的模拟框体 8, 以及探测器捕捉的基板直角和边线 9。 通过尺寸辨识系统为识别基板在 机台上的粗略位置时, 操作者首先手动输入基板尺寸, 尺寸辨识系统会在 控制屏幕上生成一个尺寸与基板相同的模拟框体 8, 机台上的探测器自动 识别出玻璃基板的直角和边线 9并显示在工作界面中。 然后, 如图 4中箭 头方向所指, 工作界面发生变化, 反映了尺寸辨识系统按预设程序将模拟 框体与捕捉到的直角和边线拟合的过程: 根据探测器识别出的直角或边 线, 尺寸辨识系统自动拟合模拟框体与直角或边线, 从而确定模拟框体的 位置; 模拟框体的位置即^ ϋ板在机台上的位置, 误差应在 10um以内。
本发明采用标记 (Mark ) 位置辨识系统做精细对位, 包括对位 CCD, 以及供操作者手动输入基板上标记的准确位置的界面, 对位 CCD 和真空贴合装置根据输入的标记位置信息移动到标记位置, 并根据标记对 基板进行精细对位。 精细对位。 标记位置辨识系统具有预先编写的程序, 向使用者提供工作界面。 使用者首先手动输入标记在基板的准确位置, 精 确至 10um; 然后对位 CCD和真空贴合装置根据输入的位置信息, 移动到 标记位置, 根据标记对基板进行精细对位。
如图 5所示, 其为本发明全世代适用的真空贴合机的工作方法的流程 图。 本发明提供了与全世代适用的真空贴合机相适应的工作方法, 包括: 步骤 10、 移载装置调节夹持头的间距以适合于基板尺寸;
步骤 20、 操作者手动输入基板尺寸, 尺寸辨识系统在控制屏幕上生成 一个尺寸与所输入的基板尺寸相同的模拟框体, 机台上的探测器自动识别 出机台上的基板的直角和边线, 尺寸辨识系统根据探测器识别出的直角或 边线自动拟合模拟框体与机台上的基板的直角或边线, 通过确定模拟框体 的位置来确定基板在机台上的位置;
步骤 30、 通过确定基板与机台的相对位置, 确定了将要进行精细对位 的基板区域, 移动对位 CCD 及真空贴合装置到基板区域; 确定了基板与 机台的相对位置, 就确定了将要进行精细对位的基板区域, 对位 CCD 是 精细对位工具, 应移动到基板区域; 真空贴合装置是贴合工具, 也应移动 到基板区域;
步骤 40、 在标记位置辨识系统中手动输入标记在基板的准确位置, 根 据输入的标记位置信息移动对位 CCD 和真空贴合装置到标记位置, 根据 标记对基板进行精细对位;
步骤 50、 精细对位完成后, 贴合开始。 从而将 TFT基板与 CF基板对 组在一起。
本发明的全世代适用的真空贴合机的工作方法可应用于如图 1 所示的 全世代适用的真空贴合机上, 在机台 11 上主要设置包括移载装置 12、 定 位装置 13、 涂胶装置 14、 翻转装置 15以及至少一个真空贴合装置 16, 其 中, 所述机台 11的尺寸足够大以适合于基板尺寸, 所述移载装置 12具有 可调节间距以适合于基板尺寸的夹持头, 所述翻转装置 15 具有足够密的 真空吸脚以适合于基板尺寸, 所述定位装置 13 包括识别基板在机台上粗 略位置的尺寸辨识系统以及对基板进行精细对位的标记位置辨识系统。
不论需要贴合的两块基板尺寸是不是标准尺寸 (G1~G10: 每种世代 均有一系列标准尺寸) , 也不论这两块基板是多少世代, 只要这两块基板 可以对组贴合, 都可以使用本发明全世代真空贴合机及其工作方法进行贴 合。
综上所述, 本发明的全世代适用的真空贴合机可对组贴合多种尺寸的
TFT与 CF基板, 特别是需要贴合不同尺寸基板的实验线。 本发明全世代 适用的真空贴合机的工作方法只需一台全世代真空贴合机即可满足多种尺 寸基板的需求, 节省机台采购成本。
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 都应属于本发明后附的权利要求的保护范围。
