 本发明的实施方式
以下各实施例的说明是参考附加的图示，用以例示本揭示可用以实施的特定实施例。本揭示所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本揭示，而非用以限制本揭示。在图中，结构相似的单元是用以相同标号表示。
实施例一
本揭示实施例一提供一种框胶涂布装置100，如图2所示，该框胶涂布装置100包括封框胶管101、覆盖于所述封框胶管101一端的封框胶管盖体102、喷嘴103以及位于所述封框胶管101另一端的支撑部104，所述支撑部104用于连接所述封框胶管101与所述喷嘴103，封框胶从所述封框胶管101内流经所述支撑部104，之后通过所述喷嘴103流出至基板上以进行后续地涂布过程。上述封框胶通常选用紫外线固化型封装胶。
由于封框胶的黏度不仅与其搁置的时间有关，还和温度有密切的关系，升高温度有利于降低封框胶的黏度。因此，该框胶涂布装置100进一步包括一加热装置105，所述加热装置105设置于所述支撑部104靠近所述喷嘴103的一端，用于对流经所述支撑部104内部的封框胶进行加热，能够降低封框胶的黏度，并有利于封框胶中残存气泡的破裂，从而减少在封框胶的涂布过程中，产生挂胶甚至断胶的现象。
为了方便控制封框胶的温度，还可在所述支撑部104外设置一温度传感器106，用于实时监控所述支撑部104的温度，确保封框胶的温度保持稳定状态。所述温度传感器106可选用红外线温度传感器或热电偶传感器，因此，对于所述支撑部104的温度进行实时监测的方法可选用红外探测或者热电偶等检测方法。
所述支撑部104的材料选用金属材质，由于金属导热速度快，因此在所述支撑部104上增加一加热装置105可以更加快速有效地控制封框胶的温度及温度稳定性。
同时，为了使所述加热装置105与所述支撑部104紧密接触，从而减少所述加热装置105对所述支撑部104内部的封框胶加热过程中热量的浪费，所述加热装置105可套接在所述支撑部104上，用于对所述支撑部104内的封框胶进行加热。所述加热装置105的高度小于所述支撑部104的高度，因此，所述加热装置105部分覆盖所述支撑部104的外表面，并且所述加热装置105与所述支撑部104的截面形状一致，使所述加热装置105的内表面与所述支撑部104的外表面能够紧密贴合在一起，防止热量流失。
所述加热装置105为金属材质，可选择电阻丝加热的方式，在所述加热装置105的外表面缠绕有电阻丝，利用该电阻丝产生的热量对位于所述支撑部104内部的封框胶进行加热。
实施例二
如图3所示为本揭示实施例二提供的一种框胶涂布装置200，该框胶涂布装置200包括封框胶管201、覆盖于所述封框胶管201一端的封框胶管盖体202、喷嘴203以及位于所述封框胶管201另一端的支撑部204，所述支撑部204用于连接所述封框胶管201与所述喷嘴203，封框胶从所述封框胶管201内流经所述支撑部204，之后通过所述喷嘴203流出至基板上以进行后续的涂布过程。上述封框胶通常选用紫外线固化型封装胶。
该框胶涂布装置200进一步包括一加热装置205，用于对流经所述支撑部204内部的封框胶进行加热。同时，为了方便控制封框胶的温度，还可在所述支撑部204外设置一温度传感器206，用于实时监控所述支撑部204的温度，确保封框胶的温度保持稳定状态。所述温度传感器206可选用红外线温度传感器或热电偶传感器，因此，对于所述支撑部204的温度进行实时监测的方法可选用红外探测或者热电偶等检测方法。
如图4、图5所示，本实施例二中的框胶涂布装置200是在实施例一提供的框胶涂布装置100的基础上，进一步在所述支撑部204的侧壁开设凹槽207，所述加热装置205与所述凹槽207的外表面相互贴合在一起。此种将所述加热装置205与所述凹槽207相互配合的方式，使得所述加热装置205与所述支撑部204通过所述凹槽207紧密贴附在一起，避免在涂布过程中所述加热装置205的脱落，同时可有效减少该框胶涂布装置200所占空间的大小。所述凹槽207的高度小于所述支撑部204的高度，因此，所述加热装置205可部分覆盖所述支撑部204的外表面。同时，所述支撑部204为中空状，内部为容纳封框胶的腔体（图中未视出），因此，所述凹槽207的内表面与所述支撑部204腔体的侧壁应保持一定的距离，避免当所述凹槽207与所述加热装置205装配完成后，所述加热装置205与位于所述支撑部204腔体内部的封框胶发生接触，影响封框胶的品质。
如图6所示，所述加热装置205的形状与所述凹槽207的形状保持一致，由于所述凹槽207开设于所述支撑部204侧壁上，因此，所述加热装置205的形状与所述支撑部204的截面形状保持一致。若所述支撑部204的截面形状为圆环形状，则所述加热装置205的形状为圆环形状；若所述支撑部204的截面形状为四边形，则所述加热装置205的形状为四边形。进一步地，为了使所述加热装置205与所述支撑部204能够快速、方便地进行组装，以及当该框胶涂布装置200停止工作时，需要将所述加热装置205轻易地拆卸下来，可将所述加热装置205的形状设置为开口形状。如图6所示，本实施例所提供的一种加热装置206的形状为开口的四边形。
本揭示提供一种框胶涂布装置，通过在连接封框胶管与喷嘴的支撑部上设置一加热装置，可以快速有效地提高封框胶温度，控制封框胶升温速度，从而提高胶框涂布装置的生产效率及稳定性。
综上所述，虽然本揭示已以优选实施例揭露如上，但上述优选实施例并非用以限制本揭示，本领域的普通技术人员，在不脱离本揭示的精神和范围内，均可作各种更动与润饰，因此本揭示的保护范围以权利要求界定的范围为准。
