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。
参照图1，图1为本发明偏光板撕除的方法第一实施例的流程示意图。
在本实施例中，偏光板撕除的方法包括：
步骤S10，当贴附于面板上出现贴附缺陷的偏光板上的撕除角起撕后，开启保持风刀，通过保持风刀将撕除角保持在起撕后的状态；
步骤S20，移动保持风刀以及用于置放面板的撕除平台，至撕除角位于撕除组件中；
步骤S30，将撕除角夹持在撕除组件中，撕除偏光板。
当贴附偏光板的制程中出现缺陷，需要将偏光板撕除并重新进行贴附时，将贴附有偏光板的面板置放在撕除平台上，便进入偏光板撕除制程，即通过自动化的方式，在撕除平台移动的过程中，通过撕除组件将偏光板撕除。
请一并参照图3和图6a—6e，图3为保持风刀将撕除角保持在起撕后的状态的原理示意图；图6a至图6e为偏光板撕除制程中工序的进程示意图。
在本实施例中，当操作人员将出现贴附缺陷的偏光板10上的一角撕起后，该撕起的一角即可被定义为撕除角11；撕起的过程，可以通过小刀先切入偏光板10的撕除角11，再捏住撕除角11，撕起适当的长度；将贴附有偏光板10的面板20置放在撕除平台30上，本实施例为防止在偏光板10进入撕除组件的过程中撕除角无法保持在其起撕后的状态，可以通过保持风刀40，在偏光板10进入撕除组件的过程中，利用保持风刀40所吹出的高压空气，将撕除角11保持在起撕后的状态。
将贴附有偏光板10的面板20置放在撕除平台30上后，移动该撕除平台，即使其向撕除组件的方向移动，至偏光板10上的撕除角11位于撕除组件中。如图6a—6e中所示出，在本实施例中，撕除组件包括在撕除偏光板10的过程中用于夹持偏光板10的前撕除滚轮50和后撕除滚轮60，以及用于夹持撕除角11、将偏光板10撕除的撕除夹抓70。如图3中所示出，后撕除滚轮60与撕除平台的距离为h1。当偏光板10进入到撕除组件中后，在撕除平台继续沿相同的方向移动的过程中，通过撕除组件对偏光板10的夹持，及撕除平台30与撕除组件的相对运动，将偏光板10撕除。至此，完成偏光板10撕除制程。
本发明实施例，通过当贴附于面板20上的偏光板10的撕除角11起撕，并将面板20置放在撕除平台30上后，开启保持风刀40，通过保持风刀40所吹出的高压空气将撕除角11保持在起撕后的状态；移动撕除平台30和保持风刀40，至撕除角11位于撕除组件中，并在撕除组件夹持撕除角11后，通过撕除平台30与撕除组件的相对运动，将偏光板10撕除。采用这种方法来完成偏光板10撕除制程，能够满足偏光板10撕除制程的半自动化，从而可以简化人工作业，并且在保证降低工安风险的同时，能够提高偏光板10撕除制程的可控性。
参照图2，图2为图1中所示出的将撕除角保持在起撕后的状态的流程示意图。
在本实施例中，步骤S10包括：
步骤S11，将保持风刀对准撕除角撕离面板的一面；
步骤S12，开启保持风刀，通过其所吹出的高压空气，将撕除角保持在起撕后的状态。
请一并参照图3，图3为保持风刀将撕除角保持在起撕后的状态的原理示意图。
在撕除平台30上固定保持风刀40时，将其对准撕除角11从偏光板10撕离的一面，然后开启保持风刀40，使其吹出高压空气，本实施例中，保持风刀40所吹出的高压空气的压力，可以根据需要进行调节；并且，在选择保持风刀40时，选择角度可调节的保持风刀40。将保持风刀40吹出的高压空气的压力和角度调整至适当的大小，即可将撕除角11保持在起撕后的状态。
在本实施例中，如图中3所示出，在后撕除滚轮60的下方，还设置有用于在撕除偏光板10的过程中将面板20抵住的抵持滚轮（图中未示出），该抵住滚轮与撕除平台30的距离为h2；a为保持风刀40吹出高压空气的角度。
h2需要保持在适当的范围内，如h2过大，则在撕除偏光板10的过程中，面板20的弯曲度就会过大，从而容易发生面板20破片的现象；而如h2过小，则在撕除平台30前进的过程中，抵住滚轮距离面板20就会过近，因此，有可能会将面板20划伤。
当确定了h2的大小后，由于后撕除滚轮60位于抵住滚轮的上方，因此，首先需保证h1>h2。而如果h1过大，则偏光板10的撕除角11若要靠在后撕除滚轮60上，人工撕起的撕除角11的范围就需要越大，这样，面板20破片的风险就会相应提高，因此，h1在保证大于h2的前提下，可设置在较小的范围。
为满足偏光板10能够靠在后撕除滚轮60上的要求，保持风刀40吹出高压空气的角度a所在的直线，与撕除平台30的距离就需要大于h1。在实际的偏光板10撕除制程中，由于所选择的保持风刀40的角度可调节，即可以根据不同的需求对a进行相应的调整。
在撕除平台30移动的过程中，将保持风刀40对准撕除角11撕离面板20的一面；并开启保持风刀40，通过其所吹出的高压空气，不断地吹向偏光板10的撕除角11，从而将撕除角11始终保持在起撕后的状态。这就能够进一步保证满足偏光板10撕除制程的半自动化要求，并且在进一步保证提高偏光板10撕除制程的可控性的同时，可以提高制程良率。
参照图4，图4为图1中所示出的移动撕除平台和保持风刀的流程示意图。
在本实施例中，步骤S20包括：
步骤S21，同时移动保持风刀和用于置放面板的撕除平台，至撕除角靠在后撕除滚轮上；
步骤S22，将前撕除滚轮下压，至撕除角位于前撕除滚轮和后撕除滚轮之间。
参照图5，图5为图1中所示出的撕除偏光板的流程示意图。
在本实施例中，步骤S30包括：
步骤S31，将撕除夹抓移动至前撕除滚轮和后撕除滚轮上方；
步骤S32，当撕除角进入撕除夹抓后，将撕除角夹持在撕除夹抓中，将偏光板撕除。
请一并参照图6a和图6b，图6a为面板置放在撕除平台上、撕除角进入撕除组件之间的示意图；图6b为撕除角靠在后撕除滚轮上后将前撕除滚轮下压的示意图。
如图6a中所示出，当将偏光板10的撕除角11撕起适当的长度，将贴附有偏光板10的面板20置放在撕除平台30上后，同时移动撕除平台30和保持风刀40，使在撕除平台30的过程中，保持风刀40能够不断地吹出高压空气，来保持偏光板10撕除角11的起撕后的状态。在此过程中，如图6b中所示出，前撕除滚轮50远离后撕除滚轮60而位于其上方，当撕除角11靠在后撕除滚轮60上后，将前撕除滚轮50向下压，使前撕除滚轮50沿图中箭头所指示的方向移动至与后撕除滚轮60位于同一水平线上，并且将撕除角11夹紧在前撕除滚轮50和后撕除滚轮60之间。
当用于置放面板20的撕除平台30和保持风刀40同时移动至撕除角11靠在后撕除滚轮60上后，将前撕除滚轮50下压至撕除角11位于前撕除滚轮50和后撕除滚轮60之间，通过前撕除滚轮50和后撕除滚轮60将撕除角11夹紧。这样，就可以为撕除平台30继续前进的过程中，偏光板10的撕除角11能够顺利进入撕除夹抓70中，提供了有力的前提保证。
请一并参照图6c、图6d和图6e，图6c为撕除夹抓就位后的示意图；图6d为撕除角进入撕除夹抓后的示意图；图6e为撕除夹抓夹持撕除角，撕除偏光板过程的示意图。
如图6c中所示出，当将前撕除滚轮50下压至将撕除角11夹紧在前撕除滚轮50和后撕除滚轮60之间后，将撕除夹抓70就位，即将其移动至前撕除滚轮50和后撕除滚轮60的上方。如图6d中所示出，随着撕除平台30的继续移动，前撕除滚轮50和后撕除滚轮60夹紧偏光板10的撕除角11，逐渐将偏光板10贴附在面板20上的剩余部分撕起，偏光板10在前撕除滚轮50和后撕除滚轮60之间向上延伸，至撕除角11被送入至撕除夹抓70中。如图5e中所示出，此时，撕除夹抓70确认偏光板10进入后，夹持偏光板10，并随着撕除平台30同时且沿着相同的方向移动，而前撕除滚轮50和后撕除滚轮60是固定的，这样，通过撕除夹抓70的夹持作用，偏光板10在前撕除滚轮50和后撕除滚轮60之间继续向上延伸，最终被完全撕除。这就完成了偏光板10撕除制程。
在偏光板10的撕除角11被夹紧在前撕除滚轮50和后撕除滚轮60之间后，将撕除夹抓70移动至前撕除滚轮50和后撕除滚轮60上方；以便当撕除角11进入撕除夹抓70后，将撕除角11夹持在撕除夹抓70中，通过撕除夹抓70的夹持作用，将偏光板10完全撕除，从而完成偏光板10撕除制程。这样，既满足了偏光板10撕除制程的半自动化，并且能够进一步使人工作业更为简化，同时，也可以进一步保证降低工安风险，提高制程良率。

将贴附有偏光板10的面板20置放在撕除平台30上后，通过移动模块002移动该撕除平台，即使其向撕除组件的方向移动，至偏光板10上的撕除角11位于撕除组件中。如图6a—6e中所示出，在本实施例中，撕除组件包括在撕除偏光板10的过程中用于夹持偏光板10的前撕除滚轮50和后撕除滚轮60，以及用于夹持撕除角11、将偏光板10撕除的撕除夹抓70。如图3中所示出，后撕除滚轮60与撕除平台的距离为h1。当偏光板10进入到撕除组件中后，在撕除平台继续沿相同的方向移动的过程中，通过撕除模块003，利用撕除组件对偏光板10的夹持，及撕除平台30与撕除组件的相对运动，将偏光板10撕除。至此，完成偏光板10撕除制程。

参照图9，图9为图7中所示出的移动模块的结构示意图。
在本实施例中，移动模块002包括：
第一移动单元0021，用于同时移动保持风刀和用于置放面板的撕除平台，至撕除角靠在后撕除滚轮上；
下压单元0022，用于将前撕除滚轮下压，至撕除角位于前撕除滚轮和后撕除滚轮之间。
参照图10，图10为图7中所示出的撕除模块的结构示意图。
在本实施例中，撕除模块003包括：
第二移动单元0031，用于将撕除夹抓移动至前撕除滚轮和后撕除滚轮上方；
撕除单元0032，用于当撕除角进入撕除夹抓后，将撕除角夹持在撕除夹抓中，将偏光板撕除。
请一并参照图6a和图6b，如图6a中所示出，当将偏光板10的撕除角11撕起适当的长度，将贴附有偏光板10的面板20置放在撕除平台30上后，通过第一移动单元0021同时移动撕除平台30和保持风刀40，使在撕除平台30的过程中，保持风刀40能够不断地吹出高压空气，来保持偏光板10撕除角11的起撕后的状态。在此过程中，如图6b中所示出，前撕除滚轮50远离后撕除滚轮60而位于其上方，当撕除角11靠在后撕除滚轮60上后，通过下压单元0022将前撕除滚轮50向下压，使前撕除滚轮50沿图中箭头所指示的方向移动至与后撕除滚轮60位于同一水平线上，并且将撕除角11夹紧在前撕除滚轮50和后撕除滚轮60之间。
当用于置放面板20的撕除平台30和保持风刀40同时移动至撕除角11靠在后撕除滚轮60上后，将前撕除滚轮50下压至撕除角11位于前撕除滚轮50和后撕除滚轮60之间，通过前撕除滚轮50和后撕除滚轮60将撕除角11夹紧。这样，就可以为撕除平台30继续前进的过程中，偏光板10撕除能够顺利进入撕除夹抓70中，提供了有力的前提保证。
请一并参照图6c、图6d和图6e，如图6c中所示出，当将前撕除滚轮50下压至将撕除角11夹紧在前撕除滚轮50和后撕除滚轮60之间后，将撕除夹抓70就位，即通过第二移动单元0031将其移动至前撕除滚轮50和后撕除滚轮60的上方。如图6d中所示出，随着撕除平台30的继续移动，前撕除滚轮50和后撕除滚轮60夹紧偏光板10的撕除角11，逐渐将偏光板10贴附在面板20上的剩余部分撕起，偏光板10在前撕除滚轮50和后撕除滚轮60之间向上延伸，至撕除角11被送入至撕除夹抓70中。如图5e中所示出，此时，撕除夹抓70确认偏光板10进入后，夹持偏光板10，并随着撕除平台30同时且沿着相同的方向移动，而前撕除滚轮50和后撕除滚轮60是固定的，这样，通过撕除夹抓70的夹持作用，偏光板10在前撕除滚轮50和后撕除滚轮60之间继续向上延伸，最终被完全撕除。这就完成了偏光板10撕除制程。
在偏光板10的撕除角11被夹紧在前撕除滚轮50和后撕除滚轮60之间后，将撕除夹抓70移动至前撕除滚轮50和后撕除滚轮60上方；以便当撕除角11进入撕除夹抓70后，将撕除角11夹持在撕除夹抓70中，通过撕除单元0032，利用撕除夹抓70的夹持作用，将偏光板10完全撕除，从而完成偏光板10撕除制程。这样，既满足了偏光板10撕除制程的半自动化，并且能够进一步使人工作业更为简化，同时，也可以进一步保证降低工安风险，提高制程良率。
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。
