Description

剥离装置和方法 技术领域
本发明涉及显示技术领域， 尤其涉及一种剥离装置和方法。 背景技术
传统的显示都是玻璃平板显示， 不可以随意弯曲。 未来显示的趋 势是希望在柔性体上实现展示大量的信息即柔性显示。 目前可以实现 柔性显示的显示技术有 LCD、 OLED、 EPD (电子纸显示）、 PDLC (聚 合物分散液晶） 、 CHLC (胆 相液晶）模式。 基板主要有超薄玻璃、 金 属箔片、 塑料这三种方式。
超薄玻璃基板的水汽、 氧阻隔性能好， 透明性好， 但是它对裂纹 缺陷很敏感， 抗沖击性、 弯折性很差， 不易实现卷对卷 （roll to roll ) 的工艺， 开发超薄可挠曲的玻璃很难实现。 金属箔片基板具有阻隔水 氧的功能， 耐高温低成本， 本身具有延展性， 易于实现卷对卷工艺， 但是箔片表面粗糙通常较大 (Ra=0.6um), 即使经过抛光处理后， 仍然需 要镀上平坦化层， 这增加了器件的厚度， 对于 TFT (薄膜晶体管） 特 性也会产生不利影响。 塑料基板柔韧性更好、 质量更轻、 更耐沖击， 是很有潜力的柔性显示基材。 制作时通常将塑料基材贴附到玻璃基板 上， 然后进行阵列工艺、 有机 EL (电致发光） 蒸镀工艺、 封装和 IC 接合等操作， 再将塑料基材从玻璃基板上剥离掉。 现有技术中的一种 机械剥离方法如图 1所示， 是用一个辊轮 1将塑料膜材 2卷带下来， 由于塑料膜材在与玻璃基板 3 接触的界面存在粘附层， 有一定的粘结 力， 在卷带的过程中会出现塑料膜材与辊轮下表面之间有小间隙导致 塑料膜材小角度弯折， 进而导致塑料膜材上表面的膜层结构出现微裂 纹， 影响器件性能， 甚至导致器件层间分离， 失效。 发明内容
本发明提供了一种剥离装置和剥离方法， 能够减少塑料膜材在被 剥离过程中产生的微裂纹， 提高塑料膜材的良品率。
本发明提供了一种剥离装置， 用于将塑料膜材从玻璃基板上剥离， 所述装置至少包括第一辊轮和第一支撑件， 其中所述第一支撑件置于 玻璃基板上与塑料膜材分离的位置处， 用于支撑和 /或张紧被剥离的塑 料膜材， 所述第一辊轮， 用于将经所述第一支撑件支撑和 /或张紧的塑 料膜材卷起。
优选的， 所述第一支撑件的外表面采用弧面设计并以其弧面支撑 和 /或张紧被剥离的塑料膜材。
优选的， 所述第一支撑件为第二辊轮， 且其轴线与所述第一辊轮 的轴线平行， 并以其圆辊面支撑和 /或张紧被剥离的塑料膜材。
优选的， 所述第二辊轮的直径小于所述第一辊轮的直径。
优选的， 所述第一辊轮的柱长与所述第二辊轮的柱长相等。
优选的， 所述剥离装置还包括连接杆， 且所述连接杆的一端连接 在第一辊轮的轮轴端上， 另一端连接在第一支撑件上， 用于固定所述 第一辊轮和所述第一支撑件之间的相对位置。
优选的， 所述连接杆为两个， 分别位于第一辊轮和第一支撑件的 两侧， 以在每一侧将第一辊轮和第一支撑件彼此连接。
优选的， 所述第一辊轮的圆辊面与所述第一支撑件不接触。
优选的， 所述剥离装置还包括： 第二支撑件， 所述第二支撑件通 过连接杆分别与第一支撑件和第一辊轮相连。
本发明提供了一种剥离方法， 采用上述任一项所述的剥离装置将 塑料膜材从玻璃基板上剥离， 该方法包括：
步骤 S 1 , 将待剥离的塑料膜材的边缘部段从玻璃基板上剥离； 步骤 S2 , 将第一辊轮和第一支撑件放置在玻璃基板上， 将所剥离 的塑料膜材绕过第一支撑件；
步骤 S3 , 将绕过第一支撑件的塑料膜材固定在第一辊轮上； 步骤 S4 , 转动所述第一辊轮以将所述塑料膜材剥离。
本发明提供的剥离装置中， 在玻璃基板上与塑料膜材分离的位置 处设置用于将被剥离的塑料膜材支撑和 /或张紧的第一支撑件。 由于在 将塑料膜材之前， 所述第一支撑件对所述塑料膜材具有张紧和 /或支撑 作用， 可以使得所述塑料膜材在从玻璃基板被剥离时， 弯折出来的角 为圆角， 减小弯折时在塑料膜材中出现的应力， 从而能够减少塑料膜 材出现裂纹， 提高塑料膜材的良品率。 附图说明 图 1为现有技术中的一种剥离装置的结构示意图；
图 2为本发明实施例一提供的一种剥离装置的结构示意图； 图 3为本发明实施例二提供的一种剥离装置的结构示意图； 图 4为本发明实施例提供的一种剥离方法的流程示意图。 具体实施方式
下面结合附图和实施例， 对本发明的具体实施方式作进一步描述。 以下实施例仅用于更加清楚地说明本发明的技术方案， 而不能以此来 限制本发明的保护范围。
实施例一
本发明实施例一提供了一种剥离装置， 用于将塑料膜材从玻璃基 板上剥离， 如图 2所示， 该装置包括第一辊轮 1和第一支撑件 4。
其中第一支撑件 4置于玻璃基板 3上与塑料膜材 2分离的位置处， 用 于支撑和 /或张紧被剥离的塑料膜材 2 ,第一辊轮 1用于将经第一支撑件 4 支撑和 /或张紧的塑料膜材 2卷起。
结合图 2可以看出， 由于第一支撑件 4的支撑和 /或张紧作用， 塑料 膜材 2被剥离的过程中被弯折的角为圆角或大的弯折角， 这样塑料膜材 2在被剥离的过程中就不会因为被弯折的角度过于尖锐而导致塑料膜 材 2上出现微裂纹， 从而提高了塑料膜材 2的良品率。
优选的， 第一支撑件 4的外表面采用弧面设计并以其弧面支撑和 / 或张紧被剥离的塑料膜材 2。 通过这种结构， 能够使塑料膜材 2被弯折 的角更加圆滑， 更好的避免塑料膜材 2在被剥离的过程中产生微裂纹。
需要指出的是， 本发明优选的实施方式并不能理解为本发明保护 范围的限定， 实际应用中， 第一支撑件可以不采用弧面设计， 采用内 角为钝角的多边形 （比如正六边形或者 12变形） 也可以避免塑料膜材 产生过于尖锐的角， 从而避免塑料膜材的微裂纹。
优选的， 如图 2所示， 第一支撑件 4为第二辊轮， 第二辊轮的轴线 与第一辊轮 1的轴线平行，并以其圆辊面支撑和 /或张紧被剥离的塑料膜 材 2。
使用辊轮作为第一支撑件能够减小塑料膜材 2与第一支撑件之间 的摩擦， 避免在塑料膜材 2上产生划痕。
优选的， 如图 2所示， 第二辊轮的直径小于第一辊轮 1的直径。 在避免塑料膜材上面的膜层结构出现微裂纹的前提下， 设置第二 辊轮的直径小于第一辊轮 1 , 能够减轻第二辊轮 4的重量， 降低剥离的 难度。
优选的， 第一辊轮 1的柱长与第二辊轮的柱长相等。
这样更有利于整个剥离装置结构的稳定。
优选的， 还可以设置一个如图 2所示的连接杆 5 , 且连接杆 5 , 且连 接杆 5的一端连接在第一辊轮 1的轮轴端上， 另一端连接在第一支撑件 4 上， 用于固定第一辊轮 1和第一支撑件 4之间的相对位置。
这样由于第一辊轮对第一支撑件的支撑和 /或张紧作用， 即使第一 支撑件的重量较小， 也不会翘起， 使得第一支撑件始终处于塑料膜材 从玻璃基板上被剥离的位置。 这样就能够允许在实际应用中， 将第一 支撑件设置的较小， 降低了制作第一支撑件的成本。
当第一支撑件为第二辊轮时， 可以在连接杆的两端各设置一个凹 槽 （或孔） ， 并在两个辊轮同一端端面的圆心位置各设置一个沿轴线 方向的突起， 连接杆的凹槽 （或孔） 套在突起上； 或者连接杆的两端 各设置一个垂直于所述连接杆的突起， 并在两个辊轮同一端端面的圆 心位置各设置一个凹槽， 将连接杆的突起插入到相应的凹槽中。
优选的， 上述的连接杆 5可以为两个， 分别位于第一辊轮 1和第一 支撑件 4的两侧 , 以在每一侧分别将第一辊轮 1和第一支撑件 4彼此连 接。 当第一支撑件 4为第二辊轮时， 可以将第一辊轮和第二辊轮的相同 侧的辊轴端两两连接。
具体连接的方式与上述的在一端的连接一致， 在此不再详细说明。 这样更有利于保持两个辊轮的相对位置。
优选的 , 第一辊轮 1的圆辊面与第一支撑件 4不接触。
实施例二
本实施例与实施例一的区别在于， 该装置如图 3所示包括第二支撑 件 6 , 第二支撑件 6和第一支撑件 4之间通过连接杆 7相连， 且与第一辊 轮 1通过连接杆 8相连。 由于第一支撑件、 第二支撑件、 第一辊轮之间 通过连接杆连接形成了稳定的三角结构， 能够使得第一支撑件 4在塑料 膜材 2被剥离的过程中不被塑料膜材掀起。
相应的， 如图 3所示， 第二支撑件 6也可以为一个辊轮， 其与第一 辊轮 1以及与第一支撑件 4之间的连接方式可以与上述的第一辊轮 1与 第一辊轮之间的连接方式一致， 在此不再详细说明。
基于相同的构思， 本发明还提供了一种剥离方法， 采用上述任一 项所述的剥离装置将塑料膜材从玻璃基板上剥离， 下面结合图 2和图 4 以第一支撑件为第二辊轮为例对本发明提供的剥离方法进行进一步说 明， 该方法包括：
步骤 S1 , 将塑料膜材 2的边缘部段从玻璃基板 3上剥离。
实际应用中， 可以使用薄刀片从一端将塑料膜材 2从玻璃基板 3上 剥离开来。
步骤 S2 , 将第一辊轮 1和第二辊轮放置在玻璃基板上， 将所剥离的 塑料膜材 2绕过第二辊轮， 以使该第一支撑件的部分外表面被塑料膜材 包络。
步骤 S3 , 将绕过第二辊轮的塑料膜材固定在第一辊轮 1上。
如图 2所示， 将已经剥离的部分绕过第二辊轮， 之后可以用胶带粘 在第一辊轮 1上。
步骤 S4 , 转动第一辊轮 1将塑料膜材剥离。
结合图 2 , 在步骤 S4中， 第一辊轮 1在玻璃基板上向右滚动， 并带 动第二辊轮向右滚动， 由于第一辊轮 1的支撑和 /或张紧作用， 塑料膜材 2在从玻璃基板 3上被剥离之后被折向反方向时， 弯折产生的角为圆角， 这样就可以避免塑料膜材 2上出现微裂纹， 从而提高了塑料膜材 2的良 品率。
本领域技术人员可以理解， 当上述的剥离装置还包括第二支撑件 时， 还需要将塑料膜材 2绕过第二支撑件， 其使用时的情况可如图 2所 示。
以上所述仅是本发明的优选实施方式， 应当指出， 对于本技术领 域的普通技术人员来说， 在不脱离本发明技术原理的前提下， 还可以 做出若干改进和润饰， 这些改进和润饰也应视为本发明的保护范围。 举例而言， 支撑件的数量不限于本申请所列举的两个或三个， 可以设 置四个或四个以上的支撑件。
