[0067] 具体地, 所述第二光源 21的部分光线直接照射于所述显示屏 9的正面 901, 所述 第二光源 21的部分光线由第三反射镜 22反射至所述显示屏 9的正面 901, 提高了 第二光源 21的光线利用率, 照射至显示屏 9的正面 901的光线强度增加, 光固化 效果佳。
[0068] 具体地, 所述显示屏 9通过所述承载装置 3的第一传动带 31由上一工位依次传送 至第一光源 11下方、 第二光源 21下方或依次传送至第二光源 21下方、 第一光源 1 1下方, 再进入下一工位, 由第二光源 21下方或第一光源 11下方传送至下一工位 的过程中 (即在光固化工位的末段行程) , 连接于显示屏 9且下垂的柔性电路板 由第二传动带 332传送至与显示屏 9平齐, 第二传动带 332沿第二传动带 332的传 送方向斜向上设置, 整个过程无需人工搬动显示屏 9, 有利于提高生产效率、 降 低生产成本, 且可以避免人工搬运显示屏 9而导致显示屏 9受损, 而且柔性电路 板可以与显示屏 9平齐进入下一工位。
[0069] 具体地, 通过位于所述第一光源 11、 第二光源 21的下方且位于显示屏 9上方的 挡板 5对显示屏 9进行隔热, 且第二光源 21发出的光线可以通过挡板 5上的透光孔 501射向显示屏 9的正面 901, 所述挡板 5既可以避免温度过高导致显示屏 9产品不 良, 又不影响对显示屏 9的正面 901进行照射。
[0070] 本发明实施例所提供的显示屏光固化方法, 其过程可以参考如下, 将显示屏 9
由承载装置 3的第一传动带 31传送依次经过第一光源 11、 第二光源 21下方或依次 经过第二光源 21、 第一光源 11下方; 显示屏 9经过第一光源 11的下方的过程中, 第一反射镜 121将第一光源 11斜向向下射出的部分光线直接反射至显示屏 9的侧 面 903, 第二反射镜 122将第一光源 11向上射出的部分光线反射至第一反射镜 121 , 第一反射镜 121再将由第二反射镜 122反射而来的光线反射至显示屏 9的侧面 90 3, 从显示屏 9的侧面 903对显示屏 9中的 UV胶进行光固化。 在显示屏 9经过第一光 源 11的下方的过程中, 为避免温度过高, 通过在第一光源 11的正下方设置挡板 5 , 以避免第一光源 11直接照射显示屏 9的正面 901 ; 在显示屏 9经过第二光源 21的 下方的过程中, 第二光源 21直接照射或通过挡板 5的透光孔 501直接照射显示屏 9 的正面 901, 第三反射镜 22将第二光源 21向上射出的部分光线直接反射至或透过 透光孔 501反射至显示屏 9的正面 901, 从显示屏 9的正面 901对显示屏 9中的 UV胶 进行光固化。 可以理解地, 若取消挡板 5, 显示屏 9在经过第一光源 11、 第二光 源 21下方或依次经过第二光源 21、 第一光源 11下方的过程中, 其侧面 903、 正面 901可能被同吋照射。 显示屏 9在第一传动带 31上向下一工位 (下一工位可为洗 净工位) 传送的过程中, 连接于显示屏 9的柔性电路板自然下垂于第一传动带 31 一侧的间隙 300中, 显示屏 9在接近下一工位吋, 柔性电路板由位于间隙 300内且 斜向上设置的第二传动带 332承托至与显示屏 9平齐, 显示屏 9和柔性电路板可以 以平齐的状态进入下一工位, 自动化程度高。
[0071] 本发明实施例所提供的显示屏光固化方法, 其通过采用第二光源 21对显示屏 9 的正面 901进行照射以对 UV胶进行固化, 并先后或同吋采用第一光源 11对显示屏 9的侧面 903进行照射以对 UV胶进行辅助固化, 固化率高, 产品质量佳。
[0072] 以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在本发明的 精神和原则之内所作的任何修改、 等同替换或改进等, 均应包含在本发明的保 护范围之内。
