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
以下结合说明书附图及具体实施例进一步说明本发明的技术方案。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及图2，图1是本发明阻挡装置较佳实施例的结构示意图，图2是图1的阻挡装置的侧面示意图。该阻挡装置100包括第一阻挡板101及与所述第一阻挡板101一端连接的第二阻挡板102，且所述第一阻挡板101与第二阻挡板102呈夹角设置。
上述第一阻挡板101与第二阻挡板102所形成的夹角为0-90°，本实施例中第一阻挡板101与第二阻挡板102之间的夹角优选为90°。而且，上述第一阻挡板101的长度比第二阻挡板102的长度长，本实施例中，第一阻挡板101的长度为28mm，第二阻挡板102的长度为15mm。
上述第二阻挡板102未与所述第一阻挡板101连接的一端向外延伸有与所述第一阻挡板101平行的第三阻挡板103，且所述第一阻挡板101自第二阻挡板102延伸的方向与第三阻挡板103自第二阻挡板102延伸的方向相同，即第一阻挡板101与第三阻挡板103设置在第二阻挡板102的同一侧。所述第一阻挡板101、第二阻挡板102及第三阻挡板103之间围合形成阻挡槽。
结合参照图3，图3是本发明搬运装置的吸附间隔片的示意图。该搬运装置用于将间隔片201从装料盒200中取出，并将间隔片201放置在液晶面板（图未示）上来间隔两片液晶面板。该搬运装置包括吸附臂110、控制吸附臂110运动的控制装置120以及上述阻挡装置100。该吸附臂110的一端与控制装置120连接，另一端设置用于吸附间隔片201的吸附部111。吸附臂110根据所述控制装置120的控制，吸附间隔片201并带动其进行上下运动使粘合在一起的间隔片201之间的粘合度被破坏，从而使由于间隔片201间的作用力粘合在一起的间隔片从被吸附臂110吸附的间隔片201上脱离，因此搬运装置只会搬运一片间隔片201至预定位置。
上述阻挡装置100可以通过卡持装置（图未示）固定在装料盒200上，当然也可以在第一阻挡板101上设有贯穿第一阻挡板101设置的安装孔1012，通过螺钉（图未示）穿过安装孔1012并安装在装料盒200上。
所述搬运装置还可包括感应器130，该感应器130与阻挡装置100之间具有间隙，且该间隙优选为6mm。该感应器130用于检测吸附臂110所吸附的间隔片201是否通过该阻挡装置100。
参照图4及图5，图4是本发明搬运装置带动间隔片向上运动时经阻挡装置的第一阻挡板的状态示意图；图5是本发明搬运装置带动间隔片向下运动时经阻挡装置的第一阻挡板的状态示意图。如图4所示，以两片粘合的间隔片201a及201b为例，吸附臂110吸附间隔片201a及201b向阻挡装置100移动，吸附臂110运动至阻挡装置100时，该向上运动的间隔片201a及201b自吸附臂110吸附的位置处因第一阻挡板101的阻挡而呈向下弯曲状。而且间隔片201a及201b受到第一阻挡板101的阻力而发生形变，相互之间形成作用力F1和F2，使得间隔片201a及201b之间的粘合力被破坏。如图5所示，以两片粘合的间隔片201a及201b为例，吸附臂110吸附间隔片201a及201b向阻挡装置100移动，运动至阻挡装置100时，该向下运动的间隔片201a及201b自吸附臂110吸附的位置处因第一阻挡板101的阻挡而呈向上翘曲状。而且间隔片201a及201b受到第一阻挡板101的阻力而发生形变，相互之间形成作用力F3和F4，使得间隔片201a及201b之间的粘合力被破坏。经过反复多次的上下运动，由于粘合力而粘合在被吸附部111的间隔片201a上的的间隔片201b的一端将会与间隔片201a分离。
参照图6，图6是本发明搬运装置带动间隔片经阻挡装置的第二阻挡板的状态示意图。以两片粘合的间隔片201a及201b为例，间隔片201a及201b经过第一阻挡板101的阻挡后，随吸附臂110继续向前运动，由于间隔片201b的一端已经与间隔片201b分离，在第一阻挡板101的阻挡后，再由第二阻挡板102的阻挡间隔片201b随间隔片201a前进，进而使间隔片201a与间隔片201b完全分离。
本发明实施例通过第一阻挡板101对粘连在一起的间隔片201a及201b进行阻挡，破坏间隔片201a及201b之间的粘合力，然后再通过第二阻挡板102的限位阻挡，进一步破坏了间隔片201a及201b之间的粘合度，使得间隔片上的间隔片201b从间隔片201a上脱离，从而避免了多片间隔片进入液晶面板的包装箱造成液晶面板的破裂异常现象。
参照图7，图7是本发明搬运装置带动间隔片经阻挡装置的第三阻挡板的状态示意图。当吸附臂110吸附间隔片201a及201b向前运动时，经过第一阻挡板101和第二组挡板102的阻挡后，粘合力较小的两片间隔片，已经分离；而粘合力较大的两片间隔片则会在吸附臂110的带动下继续移动，以粘合的间隔片201a及201b为例，当吸附臂110吸附间隔片201a及201b并上下运动时，吸附臂110所吸附的间隔片201a及201b经过第三阻挡板103的阻挡，从而可以进一步破坏间隔片之间的粘合度，使间隔片201b从间隔片201a上脱离。
本实施例中，通过设置第三阻挡版103进一步阻挡粘连在一起的间隔片201，从而可以更有效地防止多片间隔片201同时进入包装箱。
再参照图1及图2，上述第一阻挡板101未与第二阻挡板102连接的一端具有第一倒角部1011。通过设置第一倒角部1011，使得间隔片201经过该第一阻挡板101并向前运动时，避免第一阻挡板101阻挡间隔片201向前运动，而造成间隔片201无法向前移动，并且脱落的间隔片201也更容易沿该第一倒角部1011滑落至装料盒200中。同理，所述第三阻挡板103未与第二阻挡板102连接的一端具有第二倒角部1031。上述第一倒角部1011与第二倒角部1031上均设有防静电涂层，优选为UPE。该防静电涂层可以使得间隔片在经过第一倒角部1011及第二倒角部1031时，有效消除因相互摩擦而产生的静电。
参照图8，图8是本发明搬运方法第一实施例的流程示意图。该搬运方法所使用的搬运装置可参照前面所述及图3至图6所示，在此就不再赘述。该搬运方法包括以下步骤：
步骤S810、控制吸附臂110吸附间隔片；
步骤S820、控制吸附臂110带动间隔片向前运动，并在经过阻挡装置100的第一阻挡板101时，控制吸附臂110进行上下运动第一预置时间；
步骤S830、控制吸附臂110向前移动并经过阻挡装置100的第二阻挡板102的阻挡；
步骤S840、控制吸附臂110移动至预定位置后，控制吸附臂110与间隔片脱离。
以两片粘合的间隔片201a及201b为例，吸附臂110吸附间隔片201a及201b后向前运动，运动至阻挡装置时，上下运动的间隔片201a及201b经过阻挡装置100中第一阻挡板101的阻挡后，间隔片201a及201b受到第一阻挡板101的作用力而发生形变，相互之间形成作用力，使得间隔片201a及201b之间的粘合力被破坏。经过反复多次的上下运动，间隔片201b一端将会与间隔片201a分离。
然后吸附的间隔片201a及201b随吸附臂110向前运动，经过第二阻挡板102时，第二阻挡版102阻挡间隔片201b与间隔片201a分离的一端，从而阻挡间隔片201b移动。
本发明实施例通过控制吸附臂110的运动，使得被吸附臂110吸附的间隔片在第一阻挡板101及第二阻挡板102的作用，破坏了间隔片之间的粘合力，使得多余的间隔片从吸附臂110上脱离，从而避免了多片间隔片进入液晶面板的包装箱而造成液晶面板破裂的异常现象。
参照图9，图9是本发明搬运方法的第二实施例的流程示意图。在第一实施例的基础上，上述步骤S830之后还包括：
步骤S850、控制吸附臂110向前移动，并在经过阻挡装置100的第三阻挡板103时，控制吸附臂110进行上下运动第二预置时间。
当吸附臂110吸附间隔片向前运动时，经过第一阻挡板101和第二组挡板102的阻挡后，粘合力较小的两片间隔片，已经分离；而粘合力较大的两片间隔片则会在吸附臂110的带动下继续移动，以粘合的间隔片201a及201b为例，当吸附臂110吸附间隔片201a及201b并上下运动时，吸附臂110所吸附的间隔片201a及201b经过第三阻挡板103的阻挡，从而可以进一步破坏间隔片之间的粘合度，使间隔片201b从间隔片201a上脱离。
参照图10，图10是本发明搬运方法第三实施例的流程示意图。在第一实施例或第二实施例的基础上，上述步骤S830之后还包括：
步骤S860、检测吸附臂100吸附的间隔片是否通过阻挡装置，是则转入步骤S840；否则返回步骤S860。
在间隔片在从装料盒中取出后，由感应器检测该间隔片是否已经完全通过阻挡装置，从而使间隔片可以更精准地放置在包装箱中，减少间隔片对液晶面板的影响。
以上所述仅为本发明的优选实施例，并非因此限制其专利范围，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，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。
