Description

紫外光固化设备及承载平台 技术领域
本公开涉及一种紫外光固化设备及承载平台。
背景技术
曲面屏幕使人眼到屏幕上各点的距离相等，提供了更宽广的视野和更为强烈的临场感。基于上述特性，曲面屏幕应用在液晶电视中则可以使用户在客厅中也能享受到类似于IMAX(Image Maximum，巨幕电影)的观影感受，因此曲面液晶电视已经成为人们的研究热点之一。
在液晶面板的制程中，紫外光固化制程(UVM，Ultraviolet curing)对于液晶的配向过程起着关键的作用。紫外光固化制程的基本原理为：将液晶面板运送至UVM机台后，对液晶面板进行紫外线曝光，之后即可完成配向制程。因此，对于曲面液晶面板来说，如何设计适于制造曲面液晶面板的UVM制程是亟待解决的问题。
发明内容
本公开提供一种紫外光固化设备及承载平台。
一种紫外光固化设备，包括：
承载平台，设置为承载柔性液晶面板；以及
紫外线照射装置，设置为对所述柔性液晶面板利用紫外线进行照射，其中，所述承载平台的用于承载所述柔性液晶面板的表面为曲面。
一种承载平台，应用于紫外光固化设备中，且所述承载平台设置为承载柔性液晶面板，其中，所述承载平台的用于放置所述柔性液晶面板的表面为曲面。
一种紫外光固化设备，包括：承载平台，具有用于承载柔性液晶面板的可调节的承载表面；以及光源，设置为照射承载于所述承载平台的承载表面的柔性液晶面板。
所述承载平台包括多个垂直设置的支撑杆，所述多个支撑杆可沿着垂直方向移动，所述多个支撑杆的顶端构成所述可调节的承载表面。
附图说明
图1为一实施例提供的紫外光固化设备的结构图；
图2为利用图1所示实施例的紫外光固化机台对液晶面板进行紫外线曝光的运行过程示意图；
图3为另一实施例提供的包含承载平台的紫外光固化设备的结构图；

具体实施方式
除非另有定义，本文所使用的所有的技术和科学术语与属于公开的技术领域的技术人员通常理解的含义相同。本文中在公开的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在限制本公开。本文所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
请参考图1、图2，一实施例提供了一种紫外光固化设备100，包括紫外线照射装置110及承载平台120。其中，紫外线照射装置110设置为对待形成曲面 液晶面板的液晶面板200利用紫外线进行照射，即进行紫外线曝光。液晶面板200具有柔性(即非刚性)，在所有的制造工序完成之后就成为曲面液晶面板，因此，液晶面板200只是曲面液晶面板在制造过程中的一种状态，还没有进行弯曲定型。紫外线照射装置110可以包括紫外灯111、紫外灯遮板112及反射镜113。
承载平台120用于承载液晶面板200。并且，承载平台120用于放置液晶面板200的表面的形状为曲面状，且所述曲面状与液晶面板200制造完成后的形状相同。因此，承载平台120的表面的形状与所有制造工序完成后形成的曲面液晶面板的形状相同，故本公开实施例中承载平台120的表面是按照终端产品的形状来进行设计的。例如：承载平台120的表面的形状可以为弧面状，并且所述表面中间的部位相对于所述表面的边缘部位下凹。其中，弧面是指截面图形为弧线的曲面。
在UVM制程中，请参考图2，液晶面板200在未被送入紫外光固化设备100前呈现平铺状态。当液晶面板200被放置于承载平台120上后紫外光固化设备，由于液晶面板200具有柔性，因此液晶面板200则同样跟随承载平台120的表面而呈现相应的曲面状，从而与终端产品的形状相同。这时，紫外线照射装置110对液晶面板200进行UV曝光时即可模拟终端产品来进行配向制程。
因此，本公开实施例提供的上述紫外光固化设备100使得液晶面板200以更接近终端产品的形状进行配向，改善了曲面液晶面板的视角差异问题，故上述紫外光固化设备100使得UVM进程更适于曲面液晶面板的制造。
在其中一个实施例中，所述表面的形状可以调节。换言之，承载平台120的表面可以调节为不同的曲面状。那么，在终端产品具有不同形状的情况下，所述表面的形状可以根据终端产品的形状进行相应调节，从而适于不同类型的 曲面液晶面板的制造，提高了紫外光固化设备100的应用范围。
在其中一个实施例中，请参考图1和图2，承载平台120上设有多个支撑单元121，且所有支撑单元121的顶部共同构成的形状为所述曲面状。其中，所有支撑单元121的顶部共同构成承载平台120的表面。
因此，各支撑单元121的顶部用于承载液晶面板200，并且所有支撑单元121可以通过相互之间高度的差异来形成所述曲面状。例如：处在边缘的支撑单元121的高度最高，而越靠近中间部位，支撑单元121的高度越低，并且从边缘到中间部位的各支撑单元121的高度按照一定的弧度平滑降低。另外，支撑单元121之间可以均匀分布，从而使得各液晶面板200受力均匀。
可选地，各支撑单元121的高度可以调节。当支撑单元121的高度发生改变时，由所有支撑单元121的顶部构成的形状则会相应发生变化。因此，若待形成的曲面液晶面板的形状不同，那么可以通过调节各支撑单元121的高度，来改变所有支撑单元121的顶部共同构成的形状。例如：若终端产品对应的半径较小，那么可以降低中间部位附近的支撑单元121的高度。
所有支撑单元121的高度可以统一由控制器(例如PLC控制器)来自动控制。例如：各支撑单元121可以安装在一个高度调节装置上，所述高度调节装置可以包括动力结构(例如电机)及能够带动支撑单元121进行上下移动或伸缩的机械结构。因此，控制器则可以通过动力结构来控制机械结构带动各支撑单元121进行上下移动，从而对所有支撑单元121的高度统一进行调节，以使得承载平台120的表面的形状与终端产品的形状保持一致。
支撑单元121包括顶针。其中，顶针是塑胶模具配件，设置为塑胶模具中，顶针亦可叫推杆、镶针、中针、托针等。可以理解的是，支撑单元121还可以为其他类型能够起到支撑作用的机械元件。
另外，在所述支撑单元121中，还可以包括设定数量个的起模顶杆。所述起模顶杆可以在液晶面板200曝光完成之后，将液晶面板200顶起至一定高度，从而便于机械臂将液晶面板200运送至下一个工位。
另一实施例提供了一种承载平台320，请参考图3、图4。承载平台320设置在紫外光固化设备300中，且承载平台320用于承载待形成曲面液晶面板的液晶面板400，以使液晶面板400被紫外线进行照射。
其中，紫外光固化设备300包括紫外线照射装置310及承载平台320。紫外线照射装置310设置为对待形成曲面液晶面板的液晶面板400利用紫外线进行照射，即进行紫外线曝光。液晶面板400具有柔性(即非刚性)，在所有的制造工序完成之后就成为曲面液晶面板，因此，液晶面板400只是曲面液晶面板在制造过程中的一种状态，还没有进行弯曲定型。具体的，紫外线照射装置310可以包括紫外灯311、紫外灯遮板312及反射镜313。
本公开实施例中，承载平台320用于放置液晶面板400的表面的形状为曲面状，且所述曲面状与液晶面板400制造完成后的形状相同。因此，承载平台320的表面的形状与所有制造工序完成后形成的曲面液晶面板的形状相同，故本公开实施例中承载平台320的表面是按照终端产品的形状来进行设计的。例如：承载平台320的表面的形状可以为弧面状，并且所述表面中间的部位相对于所述表面的边缘部位下凹。其中，弧面是指截面图形为弧线的曲面。
在UVM制程中，请参考图4，液晶面板400在未被送入紫外光固化设备300前呈现平铺状态，而当液晶面板400被送入紫外光固化设备300后，由于液晶面板400具有柔性，因此当被放置于承载平台320上后，液晶面板400则同样跟随承载平台320的表面而呈现相应的曲面状，从而与终端产品的形状相同。这时，紫外线照射装置310对液晶面板400进行UV曝光时即可模拟终端产品 来进行配向制程。
因此，本公开实施例提供的上述承载平台320使得液晶面板400以更接近终端产品的形状进行配向，改善了曲面液晶面板的视角差异问题，故上述承载平台320使得UVM进程更适于曲面液晶面板的制造。
在其中一个实施例中，所述表面的形状可以调节。换言之，承载平台320的表面可以调节为不同的曲面状。那么，在终端产品具有不同形状的情况下，所述表面的形状可以根据终端产品的形状进行相应调节，从而适于不同类型的曲面液晶面板的制造，提高了紫外光固化设备300的应用范围。
在其中一个实施例中，请参考图3和图4，承载平台320上设有多个支撑单元321，且所有支撑单元321的顶部共同构成的形状为所述曲面状。其中，所有支撑单元321的顶部共同构成承载平台320的表面。
因此，各支撑单元321的顶部设置为承载液晶面板400，并且所有支撑单元321可以通过相互之间高度的差异来形成所述曲面状。例如：处在边缘的支撑单元321的高度最高，而越靠近中间部位，支撑单元321的高度越低，并且从边缘到中间部位的各支撑单元321的高度按照一定的弧度平滑降低。另外，支撑单元321之间可以均匀分布，从而使得各支撑单元321受力均匀。
可选地，各支撑单元321的高度可以调节。当支撑单元321的高度发生改变时，由所有支撑单元321的顶部构成的形状则会相应发生变化。因此，若待形成的曲面液晶面板的形状不同，那么可以通过调节各支撑单元321的高度，来改变所有支撑单元321的顶部共同构成的形状。例如：若终端产品对应的半径较小，那么可以降低靠近中间部位的支撑单元321的高度。
所有支撑单元321的高度可以统一由控制器(例如PLC控制器)来自动控制，例如：各支撑单元321可以安装在一个高度调节装置上，所述高度调节装 置可以包括动力结构(例如电机)及能够带动支撑单元321进行伸缩的机械结构。因此，控制器则可以通过动力结构来控制机械结构带动各支撑单元321进行上下移动，从而对所有支撑单元321的高度统一进行调节，以使得承载平台320的表面的形状与终端产品的形状保持一致。
支撑单元321包括顶针。顶针是塑胶模具配件，设置为塑胶模具中，顶针亦可叫推杆、镶针、中针、托针等。可以理解的是，支撑单元321还可以为其他类型能够起到支撑作用的机械元件。
另外，在所有支撑单元321中，还可以包括设定数量个起模顶杆。所述起模顶杆可以在液晶面板400曝光完成之后，将液晶面板400顶起至一定高度，从而便于机械臂将液晶面板400运送至下一个工位。
本公开还提供一种紫外光固化设备，包括：承载平台和光源。
承载平台具有用于承载柔性液晶面板的可调节的承载表面。光源设置为照射承载于所述承载平台的承载表面的柔性液晶面板。柔性液晶面板用于形成曲面液晶面板。
所述承载平台包括多个垂直设置的支撑杆，所述多个支撑杆可沿着垂直方向移动，所述多个支撑杆的顶端构成所述可调节的承载表面。
可选地，所述多个支撑杆阵列排布。
可选地，所述光源设置为提供用于照射所述承载于所述承载平台的承载表面的柔性液晶面板的紫外光。
可选地，所述多个支撑杆包括顶针。
可选地，所述光源包括紫外灯、紫外灯遮板及反射镜。
可选地，所述多个支撑杆包括起模顶杆。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对 上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本公开的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对公开专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本公开构思的前提下，还可以做出若干变形和改进，这些都属于本公开的保护范围。因此，本公开专利的保护范围应以所附权利要求为准。
