Description
技术领域
本发明涉及液晶面板制作过程中,HVA配向后盒内液晶检查机的整列系统。
背景技术
液晶面板制作过程中,HVA配向后盒内液晶检查机是通过对配向后基板施加设定电压,使基板点亮,用CCD取得配向后的影像,再与机台内部预先建立好的影像进行对比,从而判断配向是否合格。对于达到2200mmX2500mm这样大规格的基板来说,基板进入检查机后在整列时基板容易出现弯曲变形,在加电压装置上升时,容易造成探针与基板的接触不良,从而造成CCD取得的影像与实际不符,造成误判。

附图说明
图1本发明液晶基板配向检查系统俯视图。
图2本发明液晶基板配向检查系统的整列机构示意图。
图3本发明另一实施例液晶基板配向检查系统的整列机构示意图。
具体实施方式
下面将结合附图对本发明做进一步说明。
如图1、图2所示,这种液晶基板配向检查系统,检查系统包括设于大尺度基板10的四个角的多组整列机构,其中整列机构由水平整列机构20和压平装置30组成。水平整列机构20由机台21、水平整列轮22、与水平整列轮22连接的整列气缸23和用于控制整列气缸的第一控制装置24组成;其中整列气缸23连接于机台21上,第一控制装置24为电磁阀,由水平整列轮22对基板10的四角边沿对基板10的位置进行调整。当基板10发生弯曲时,使用压平装置30向基板10施加纵向的压力用于压平基板10。具体如下:
压平装置30包括作用在基板10上的压轮31、与压轮31连接的压轮气缸32和用于控制压轮气缸32的第二控制装置33;其中第二控制装置33为电磁阀,安装在机台21控制盘内,两端有气管连接到压轮气缸32的两进气管,机台21通过PLC控制电磁阀的打开和关闭,当电磁阀打开时压轮气缸32会推动压轮31前进到基板10上方,当电磁阀关闭时,压轮气缸32会将压轮31拉回到复原,避免基板10搬出时与压轮31发生干涉。所述压平装置30的压轮气缸32连接于机台21上。压轮31通过固定轴34固定在一力臂35上,力臂35通过自身重力活动连接于压轮气缸32上,本实施中,如力臂35设有一孔槽36,而压轮气缸32上设有一穿过孔槽36的定位柱37。
下面通过操作过程对本检查系统做更进一步说明,以便更清楚地理解本发明。
当基板10从入料处被送进操作室后,分置于基板10四个角的八台整列机构对四边两侧进行整列,其中每个角各有一台整列机构结构做了如上的改进,即压平装置30;在整列时,基板10由于尺寸太大,又比较薄,容易发生弯曲,这时,操作压平装置30对基板10施加纵向作用力,便基板10恢复平整。图中可以看出,本申请的平压装置30是通过增加了一组压轮气缸32和电磁阀(即第二控制装置33)来达到压轮31水平方向运动以达所需的位置,并且压轮31是通过固定轴34固定于一力臂35上,而力臂35是通过自身重力活动连接于压轮气缸33上的,即压轮31由于自身重力而位于最低的位置,在压轮气缸32驱动其水平运动以向基板10内伸进时,压轮31先是抵触到基板10的边沿,在压轮31向基板10内运动时,受基板边沿的作用力压轮31慢慢抬起,依靠其自身重力压在基板10上,如果基板10发生弯曲,在受到该作用力时将恢复平整,力臂35和压轮气缸32的连接是一种活动连接方式,即孔槽36在相对固定不动的定位柱37内上下移动。
在另外的实施例中,如图3所示,也可以设计压轮31与压轮气缸32的连接方式为:压轮31通过固定轴34固定在一力臂38上,力臂38通过一力臂气缸39连接于压轮气缸32上。
尽管已经参照其示例性实施例具体显示和描述了本发明,但是本领域的技术人员应该理解,在不脱离权利要求所限定的本发明的精神和范围的情况下,可以对其进行形式和细节上的各种改变。
