Description

液晶显示器中玻璃基板的目视检查机及检查方法 技术领域
本发明属于液晶显示器生产技术领域,特别是涉及一种液晶显示器中玻璃基板的目视检查机,还涉及一种液晶显示器中玻璃基板的检查方法。
背景技术
液晶显示技术的不断发展,对液晶显示器的生产提出了很高的要求。
以薄膜场效应晶体管(Thin Film Transistor,TFT)的显示器为例,随着TFT显示屏幕的尺寸越来越大,大规格的玻璃基板也开始被广泛的应用。
现有技术中的检查基台,在对玻璃基板进行检查之前,检测者往往是通过目测的方式获取玻璃基板的坐标。
请参阅图1,所述目视检查机包括检查基台100,所述检查基台100包括检查基台主体101,待检查的玻璃基板固定于检查基台主体101上。所述目视检查机还包括两刻度器件102,所述两刻度器件102相互垂直设于检查基台主体101两侧。在将待检查的玻璃基板放置到检查基台主体101上后,检测者通过两侧的刻度器件102读出待检查的玻璃基板上某一点坐标的目测值。
现有的液晶显示器中玻璃基板的检查方式存在以下缺点:
1)、不同检查者有不同的读取结果;
2)、由于待检查玻璃基板的坐标无法精准,使得实际读取的坐标值往往与真实的坐标值之间有极大的误差,最大可达50mm。
3)、由于读取的玻璃基板的坐标资料不准确,很容易产生错误的源信息,而且一旦出现需要进行特殊检查的斜角时,只能利用光折射才能测量出,影响异常问题的解析效率;
4)、由于现有的检查仪器的倍率较大,使得视野减小,一般视野最大约5mm,经常导致无法准确检查玻璃基板上的盲区,请参阅图2,其中,图2为现有技术中目视检查机侧边。图2中的a为目视检查机侧边上的凹陷区,即为盲区。

本发明的最佳实施方式
以下各实施例的说明是参考附加的图式,用以例示本发明可用以实施的特定实施例。
图3为本发明中液晶显示器中玻璃基板的目视检查机的第一较佳实施例的结构图。
在图3所示的第一较佳实施例中,所述目视检查机包括检查基台100,检查基台100包括检查基台主体101。
请参阅图3,所述目视检查机还包括滑轨和坐标读取器(图未标)。其中,所述坐标读取器包括沿横向B1延伸的移动式标尺301以及沿纵向B2延伸的移动式标尺302。对应的,所述滑轨包括沿纵向B2延伸的滑轨303和滑轨304,以及沿横向B1延伸的滑轨305和滑轨306。
其中,移动式标尺301滑动连接滑轨303和滑轨304,移动式标尺302滑动连接滑轨305和滑轨306。
在具体实施过程中,还可以将移动式标尺301仅滑动连接滑轨303,移动式标尺302仅滑动连接滑轨305,由于原理类似,不再一一赘述。
在图3所示的第一较佳实施例中,移动式标尺301的长度方向垂直于滑轨303和滑轨304的长度方向;移动式标尺302的长度方向垂直于滑轨305和滑轨306的长度方向,且滑轨303和滑轨304的长度方向,以及滑轨305和滑轨306的长度方向均平行于检查基台主体101的水平面。
在图3所示的第一较佳实施例中,在将待检查的玻璃基板放置到检查基台主体101上后,控制移动式标尺301沿滑轨303和滑轨304的延伸方向即纵向B2滑动,同时控制移动式标尺302沿滑轨305和滑轨306的延伸方向即横向B1滑动,在移动式标尺301和移动式标尺302滑动到某一位置后,移动式标尺301和移动式标尺302在所述检查基台主体101的水平面上方交互形成一定位点D,检测者通过移动式标尺301和移动式标尺302上的刻度读取定位点D的坐标,定位点D的坐标即为待检查的液晶面板上相应的坐标,显然,本实施例实现了对待检查的液晶面板的准确定位。
而且,在图3所示的第一较佳实施例中,由于滑轨贴近所述检查基台主体101,且设置于检查基台主体101的至少相邻的两侧,因此可以获取放置在检查基台主体101上待检查的玻璃基板的任一位置的坐标,避免了由于存在图2中的读取盲区造成的检查错误的问题,保证了读取结果的准确性。
请参阅图4,图4为本发明中液晶显示器中玻璃基板的目视检查机的第二较佳实施例的结构图。
在图4所示的第二较佳实施例中,所述目视检查机包括检查基台100,检查基台100包括检查基台主体101。
其中,相对于图3所示的第一较佳实施例,在图4所示的第二较佳实施例中,所述滑轨包括沿横向C1延伸的滑轨403和沿纵向C2 延伸的滑轨404,所述坐标读取器包括发射器401,发射器402,刻度尺405以及刻度尺406。
请参阅图4,发射器401滑动设置在滑轨403上,并与刻度尺405对应;发射器402滑动设置在滑轨404上,并与刻度尺406对应。
在图4所示的第二较佳实施例中,刻度尺405的长度方向平行于滑轨403的长度方向;刻度尺406的长度方向平行于滑轨404的长度方向,且滑轨403的长度方向和滑轨404的长度方向均平行于检查基台主体101的水平面。
在图4所示的第二较佳实施例中,在将待检查的玻璃基板放置到检查基台主体101上后,控制发射器401沿滑轨403的延伸方向即横向C1滑动,同时控制发射器402沿滑轨的延伸方向即纵向C2滑动,在发射器401和发射器402滑动到某一位置后,发射器401和发射器402的光线交互形成一定位点E,检测者通过发射器401的光线对应的刻度尺405的刻度以及发射器402的光线对应的刻度尺406的刻度读取定位点E的坐标,定位点E的坐标即为待检查的液晶面板上相应的坐标,显然,本实施例实现了对待检查的液晶面板的准确定位。
而且,在图4所示的第二较佳本实施例,由于滑轨和刻度尺贴近所述检查基台主体101,且滑轨设置于检查基台主体101的相邻的两侧,刻度尺对应设置于另外两侧,因此可以获取放置在检查基台主体101上待检查的玻璃基板的任一位置的坐标,避免了由于存在图2中的读取盲区造成的测量错误的问题。
请参阅图5,图5示出了本发明中液晶显示器中玻璃基板的检查方法的第一较佳实施例的流程。
在步骤S501中,将待检查的玻璃基板固定在检查基台主体101上。
在步骤S502中,控制第一移动式标尺沿第一滑轨和第二滑轨滑动,同时控制第二移动式标尺沿第三滑轨和第四滑轨滑动。
当然,在具体实施过程中,还可以控制第一移动式标尺仅沿第一滑轨滑动,控制第二移动式标尺仅沿第三滑轨滑动,由于原理类似,此处不一一赘述。
其中,所述第一移动式标尺的长度方向垂直于所述第一滑轨的长度方向;所述第二移动式标尺的长度方向垂直于所述第三滑轨的长度方向。
其中,所述第二滑轨的长度方向平行于所述第一滑轨的长度方向,且所述第一滑轨和所述第二滑轨分居所述检查基台主体的相对两侧;所述第四滑轨的长度方向平行于所述第三滑轨的长度方向,且所述第四滑轨和所述第三滑轨分居所述检查基台主体的相对两侧。
在步骤S503中,在第一移动式标尺和第二移动式标尺滑动到某一位置后,通过第一移动式标尺和第二移动式标尺上的刻度读取相应的坐标。
在步骤S504中,根据读取的坐标以及玻璃基板的检查标准对所述待检查的玻璃基板进行处理。
其中,本发明中玻璃基板的检查标准为厂商针对玻璃基板的切割标准,或者是切割后的玻璃基板的尺寸规格等,此处不再赘述。
本发明实施例中,在将待检查的玻璃基板放置到检查基台主体上后,检测者就可以通过坐标读取器准确的读出待检查的玻璃基板上某一点的坐标,避免了现有技术中通过估测获取坐标带来的准确率低的问题。
图6示出了本发明中液晶显示器中玻璃基板的检查方法的第二较佳实施例的流程。
在步骤S601中,将待检查的玻璃基板固定在检查基台主体上。
在步骤S602中,控制第一发射器沿第五滑轨滑动,同时控制第二发射器沿第六滑轨滑动。
在步骤S603中,在第一发射器和第二发射器滑动到某一位置后,通过第一发射器的光线对应的第一刻度尺的刻度以及第二发射器的光线对应的第二刻度尺的刻度读取相应的坐标。
在步骤S604中,根据读取的坐标以及玻璃基板的检查标准对所述待检查的玻璃基板进行处理。
其中,所述第一刻度尺的长度方向平行于所述第五滑轨的长度方向,且对应所述第一发射器;所述第二刻度尺的长度方向平行于所述第六滑轨的长度方向,且对应所述第二发射器。
优选的,所述第一发射器和第二发射器均为激光笔,当然也可以是其它的能够发射光线的仪器,此处不一一列举。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
