现有技术中，偏光板制作完成后通常都是利用传送滚轮将偏光板传送定位装置的定位机台上的目标位置处，再利用利用设置于定位机台上的定位柱对偏光板的位置进行粗调，使得偏光板可位于定位机台上的粗调位置处，而后利用CCD图像传感器对粗调位置上的偏光板的位置进行精确的调整，以确保偏光板在后续的搬移过程和撕离偏光板以及撕离离形膜的过程中的位置定位。然而，受定位机台表面、偏光板厚度及偏光板表面的影响，特定的传送滚轮通常无法将所有类型的偏光板准确地传送至定位机台上的目标位置处，导致定位柱无法将偏光板移动至粗调位置处，进而导致在精调程序中，CCD图像传感器无法对偏光板的位置进行精调，降低了液晶面板的生效效率。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
请参照图1，其为本发明较佳实施方式的定位装置的结构示意图。定位装置10邻近传送滚轮80而设置，用于接收传送滚轮80所传送过来的偏光板并对该偏光板进行粗定位，以确保后续定位程序中CCD图像传感器可对已粗定位的偏光板进行精确定位，进而确保偏光板可精确地贴附至玻璃基板上。在本实施例中，定位装置10包括定位机台100、皮带传送机构200、驱动机构（图未示）、第一传感器300、第二传感器400以及定位组件。
定位机台100邻近传送滚轮80而设置，用于接收传送滚轮所传送过来的偏光板并承载该偏光板。如图1所示，在本实施例中，定位机台100的台面略低于传送滚轮80。如此，由于偏光板为软性板，从传送滚轮80所传送过来的偏光板的端部可下垂至与定位机台100的台面相接触而进入定位机台100上。在本实施例中，进一步地，定位机台100上开设有开口（图未示）。
皮带传送机构200设置于定位机台100的下方与定位机台100上开设的开口相对应的位置处并连接至驱动机构。皮带传送机构200在驱动机构的驱动作用下可相对定位机台100上升至部分显露于定位机台100的台面上方。在本实施例中，皮带传送机构200包括滚轮组210及套设于滚轮组210之上的皮带220。滚轮组210包括第一滚轮组211及第二滚轮组212，其中，第一滚轮组211靠近传送滚轮80，包括上下间隔设置的第一滚轮211a及第二滚轮211b，而第二滚轮组212则远离传送滚轮80并与第一滚轮组211相对设置，包括上下间隔设置的第三滚轮212a及第四滚轮212b。第一滚轮组211与第二滚轮组212的高度相等，从而使得套设于其上的皮带220的表面可保持水平并与定位机台100的台面大致平行。在本实施例中，第一滚轮组211及第二滚轮组212分别包括上下间隔设置的两个滚轮，且这些滚轮可为张紧轮。可以理解的是，各滚轮组中所包含的滚轮的数量并不局限于本实施例中，在其他实施例中，各滚轮组中可仅包括一个滚轮或两个以上的滚轮。
第一传感器300固定至定位机台100并与定位机台100所开设的开口相对应的位置处连接至驱动机构，用于检测偏光板是否进入定位机台100上。第一传感器300可在检测到偏光板进入定位机台100上之后输出第一检测信号至驱动机构，以使驱动机构根据该第一检测信号而运作，驱动皮带传送机构200上升。在本实施例中，第一传感器300可为光电对管，当偏光板进入定位机台100时，偏光板对应第一传感器300并覆盖于第一传感器300上方，第一传感器300的发射管发射信号并经过偏光板反射后被接收管所接收，接收管在接收到反射回来的信号后输出用以表示偏光板进入定位机台100的第一检测信号。可以理解，第一检测信号可为红外信号、高电平信号或低电平信号。
第二传感器400设置于定位机台100上邻近第一滚轮组211的位置处，位于传送滚轮80与第一传感器300之间，同时连接至驱动机构，用于检测偏光板是否被传送至定位机台100上的目标位置处。第二传感器400在检测到所述偏光板被传送至该目标位置时输出第二检测信号至所述驱动机构，以使驱动机构根据该第二检测信号而运作，驱动皮带传送机构200下降至位于定位机台100下方。在本实施例中，第二传感器400可为光敏传感器，当偏光板的一端从传送滚轮80脱离开来而进入定位机台100之后，偏光板对应第二传感器400并覆盖于光敏传感器上方，而当偏光板被传送至目标位置时，则刚好经过第二传感器400并不再覆盖于第二传感器400上方，如此，第二传感器400可依据所感测到的光强度的不同而判断偏光板是否被传送至目标位置处。
定位组件设置于定位机台100上，用于将位于目标位置上的偏光板移动至粗调位置上。在本实施例中，定位组件包括第一定位柱510及第二定位柱520，其中，第一定位柱510固定于定位机台100上远离传送滚轮80的一端上，并由定位机台100的台面向上延伸而出，第二定位柱510设置于定位机台100的下表面并位于定位机台100靠近传送滚轮80的一端处。同时，第二定位柱520还可相对定位机台100上升和/或下降，并可相对定位机台100往靠近和/或远离第一定位柱510的方向移动至对应偏光板粗调位置处，从而带动位于目标位置上的偏光板往粗调位置移动。在液晶面板制作领域中，粗调位置可依据第一定位柱510及偏光板的尺寸而确定，当偏光板移动至其远离传送滚轮的一端与第一定位柱510相抵接时即可确定偏光板已被移动至粗调位置处。
如图1所示，偏光板被送入传送滚轮80之后，在传送滚轮80的作用下偏光板朝定位机台100传送，其靠近定位装置10的一端在移出传送滚轮80之后与定位机台100的台面相接触并与第一传感器300相对应。由于在本实施例中，第一传感器300为光电对管，因此，偏光板与第一传感器300相对应之后，第一传感器300输出第一检测信号至驱动机构，驱动机构接收第一检测信号并根据该第一检测信号驱动皮带传送机构200相对定位机台100上升。如图2所示，皮带传送机构200上升至定位机台100上方之后，皮带220显露于定位机台100之上并抵顶偏光板接触定位机台100的一端。皮带传送机构200开启之后，其滚轮组210开始转动，带动皮带220一起转动。此时，在皮带220和偏光板之间的摩擦力的作用下，偏光板接触皮带220的一端跟随皮带200的转动而朝向远离传送滚轮80的方向移动，带动整张偏光板从传送滚轮80中脱离开来而传送至定位机台100上，如图3所示。此时，偏光板覆盖于皮带传送机构200上且其两端覆盖于定位机台100的台面上。
随着皮带220的转动，偏光板相对定位机台100往前移动至目标位置处。在该过程中，偏光板由对应第二传感器400移动至不再对应第二传感器400。由于在本实施例中，第二传感器为光敏传感器，因此，当偏光板移动至目标位置处而不再对应第二传感器400时，第二传感器400依据其所感测到光强度的不同而输出第二检测信号至驱动机构，驱动机构接收该第二检测信号并依据该第二检测信号停止皮带传送机构200并驱动皮带传送机构200相对于定位机台100下降至位于定位机台100的下方，如图4所示。
此时，定位组件的第二定位柱520相对定位机台100上升至显露于定位机台100的台面之上并抵接住偏光板靠近传送滚轮80的一端。而后，第二定位柱520朝第一定位柱510移动，从而带动偏光板一起朝第一定位柱510移动至偏光板远离传送滚轮的一端与第一定位柱510相抵接，如图5所示。此时，偏光板处于粗调位置上，可确保CCD图像传感器在后续精调程序中对偏光板的位置进行精确的调整。
本发明的定位装置10，通过在定位机台100的下方设置皮带传送机构200，且皮带传送机构200可相对定位机台100上升至其皮带220显露于定位机台100之上，从而使得皮带传送机构200可与偏光板从传送滚轮80上移出的部分相接触，利用皮带220与偏光板之间的相对摩擦力传送偏光板，确保整张偏光板可顺利从传送滚轮80上进入定位机台100并被传送至目标位置处。如此，可避免由于偏光板与定位机台100之间的摩擦力过大而导致的偏光板无法完全由传送滚轮80上脱离开来的现象或由于偏光板与定位机台100之间的摩擦力过小而导致的偏光板在定位机台100上移动过快并与定位组件之间相互碰撞而发生反弹的现象。
本发明进一步提供一种利用上述定位装置10对偏光板进行粗定位的定位方法，如图6所示，该定位方法包括以下步骤：
在步骤S100中，判断偏光板是否进入定位机台，若是则执行步骤S200，若否返回步骤S100。在本实施例中，利用第一传感器300来检测偏光板是否进入定位机台100。第一传感器300设置于皮带传送机构上对应定位机台上开设的开口位置处并同时连接至驱动机构。第一传感器300在偏光板进入定位机台100上之后输出第一检测信号至驱动机构，以使驱动机构根据该第一检测信号而运作，驱动皮带传送机构200上升。
在步骤S200中，上升皮带传送机构至该皮带传送机构部分显露于该定位机台上方。在本实施例中，驱动机构在接收到第一传感器300所输出的第一检测信号之后，驱动皮带传送机构200上升至皮带220显露于定位机台100之上，如此，皮带220可与偏光板移出传送滚轮的一端相接触。
在步骤S300中，开启该皮带传送机构以传送该偏光板。在本实施例中，皮带传送机构200开启之后，其滚轮组210开始转动，带动皮带220一起转动。此时，在皮带220和偏光板之间的摩擦力的作用下，偏光板接触皮带220的一端跟随皮带200的转动而朝向远离传送滚轮80的方向移动，带动整张偏光板移出传送滚轮80而传送至定位机台100上。
在步骤S400中，判断该偏光板是否被传送至定位机台上的目标位置处，若是则执行步骤S500，若否返回步骤S400。在本实施例中，利用第二传感器400来检测偏光板是否被传送至定位机台100上的目标位置处。第二传感器400设置于定位机台100上邻近第一滚轮组211的位置处并连接至驱动机构。第二传感器400在偏光板被传送至目标位置时输出第二检测信号至驱动机构，以使驱动机构根据该第二检测信号而运作，驱动皮带传送机构200下降至位于定位机台100下方。
在步骤S500中，停止该皮带传送机构并下降该皮带传送机构至该定位机台下方。
在步骤S600中，上升定位组件的第二定位柱并移动第二定位柱，带动偏光板移动至粗调位置处。在本实施例中，第二定位柱520在朝第一定位柱510移动的过程中与偏光板相抵接，从而带到偏光板一起朝第一定位柱510移动至偏光板远离传送滚轮80的一端与第一定位柱510相抵接。此时，偏光板处于粗调位置上，可确保CCD图像传感器在后续精调程序中对偏光板的位置进行精确的调整。
本发明所提供的偏光板的定位方法，通过在定位机台的下方设置皮带传送机构，且皮带传送机构可相对定位机台上升至其皮带显露于定位机台之上，从而使得皮带传送机构可与偏光板从传送滚轮上移出的部分相接触，利用皮带与偏光板之间的相对摩擦力传送偏光板，确保整张偏光板可顺利从传送滚轮上进入定位机台并被传送至目标位置处。如此，可避免由于偏光板与定位机台之间的摩擦力过大而导致的偏光板无法完全由传送滚轮上脱离开来的现象或由于偏光板与定位机台之间的摩擦力过小而导致的偏光板在定位机台上移动过快并与定位组件之间相互碰撞而发生反弹的现象。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
