步骤 2、 将偏光片 60撕去离型纸 64后， 与基板 40靠近， 使偏光片 60的贴合面 62和基板 40起始端贴合。 在实际操作中， 偏光片 60贴酎于 基板 40时， 所述基板 40可水平放置， 也可直立放置， 具体情况更具实际 的机台而定， 均可实现本发明的技术效杲。
步骤 3。 提供辊筒 80 , 并将该辊筒 80加热至 35 ；〜 70 °C， 优选的， 将 该辊筒 80加热至 60 。
所述辊筒 80包括本体 82及设于本体 82内的加热装置 84， 所述本体 82 由具有耐热性、 绝缘性及邵氏硬度 A型硬度值介于 10 98之间的材料 制成， 在本实施例中， 所述辊筒 80的本体 82由塑料制成， 可以为普通塑 料或者特殊塑料， 优选氟塑料铁氟龙， 这些材料硬度稍高于原本的橡胶材 料， 且耐热性绝缘性较好， 能提高对偏光片 60 的压力， 尽可能的避免偏 光片 60与基板 40之间气泡的产生。
所述加热装置 84可为热氷管路， 所述加热装置 84由外部水循环系统 (未图示）提供热水， 所述外部水循环系统包括水循环管路、 设于该水循 环管路内的加热设备、 设于该水循环管路内的冷却设备及电性连接于该加 热设备的控制系统。
所述热水管路及外部水循环系统均可通过现有技术实现， 仅以图 5 为 例进行原理描述， 图中加热装置 84 内的箭头方向便是水流方向， 外部水 循环系统的控制系统控制加热设备对水循环管路内的水进行加热， 加热后 的水由热水管路的进水口进入热水管路， 进而对辊筒 80的本体 82进行加 热， 然后， 水经由热水管路的出水口进入水循环管路, 经由冷却设备冷却 后储存， 以备下次使用。
步骤 4、 通过辊筒 89滚压偏光片 60， 实现偏光片 60与基板 40的贴 附压合。
在辊筒 80对偏光片 60进行压合时， 所述辊筒 80的温度保持在 35 〜70°C , 优选的， 所述辊筒 80的温度保持在 60 X：左右， 至贴附完成， 以使 该辊筒 80在压合偏光片 60的同时对偏光片 60进行加热， 使得偏光片 60 软化， 以减少或消除偏光片 60与基板 40之间的气泡， 进而缩短后续脱泡 制程的时间， 或者避免脱泡制程， 进而在很大程度上提高了生产效率， 降 低了生产成本。
综上所述， 本发明的偏光片贴附方法， 通过选用具有耐热性、 绝缘性 及特定硬度的材料制成的辊筒， 并在辊筒内设置加热装置， 使得辊筒在压 合偏光片于基板时的温度保持在 351：〜 7CTC之间， 在辊筒压合偏光片的过 程中， 对偏光片进行充分加热， 有效避免偏光片与基板之间产生气泡， 有 效缩短后续脱泡机的脱泡制程， 进而在很大程度上提高了生产效率， 降低 了生产成本。
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 都应属于本发明权利要求的保护范围。
