6,如图 4所示，通过控制部件 6控制光纤 3在垂直于封装基板 1所在平面的 方向上垂直移动， 以调节光纤 3出光一端距离封装基板 1的高度， 使得光纤 3 可将紫外光引导至靠近封装基板上待固化封框胶位置处， 进一步提高固化 效率。
进一步可选择地， 本发明实施例中的控制部件 6例如包括： 与每一光纤
3对应设置的光感应器 61 , 以及与光感应器 61和光纤 3连接的控制器 62; 光感应器 61通过封装基板反射的光,感应并确定与其对应的光纤相对封装基 板 1的位置信息， 其中， 反射光为光感应器发射的光经光纤反射后得到的； 控制器 62通过光感应器 61确定的光纤 3相对封装基板 1的位置信息， 根据 实际情况控制光纤移动。
本发明第三实施例提供的封框胶固化装置， 通过在密封箱顶部设置若干 个光纤， 光纤排布方式灵活设置， 能够减少固化时间， 提高固化效率。
本发明上述实施例提供的封框胶固化装置， 利用光纤引导紫外光源部件 发出的紫外光至封装基板的设定位置处， 并在该设定位置处曝光， 使得紫外 光源部件发出的光不会散射到其他部位， 因而不需要单独设置掩模板进行遮 挡， 因而在封框胶固化装置中无需设置掩模板， 筒化了制作工艺， 并且避免 了更换掩模板带来的产品良率下降， 固化时间长的问题。
虽然上文中已经用一般性说明及具体实施方式， 对本发明作了详尽的描 述， 但在本发明基础上， 可以对之作一些修改或改进， 这对本领域技术人员 而言是显而易见的。 因此， 在不偏离本发明精神的基础上所做的这些修改或 改进， 均属于本发明要求保护的范围。
