下面参考附图对本发明的优选实施例进行描述。
如图 1所示, 为本发明压力点检查装置第一实施例的结构示意图。 本实施例中, 压力点检查装置包括交叉安装的横向调节板和竖向调节 板。 其中: 横向调节板包括两块形状相同,呈长条状的板体, 其分别是第一横板 11 和第二横板 12, 两横板 11 , 12相平行。
在第一横板 11和第二横板 12的中部分别设置长度相同的滑槽 111 , 121 , 其作用是对装配在其中的竖向调节板进行限位。
竖向调节板包括形状相同, 且位置相互平行的两板体, 其分别是第一竖 板 21和第二竖板 22。 以下以第一竖板 21为例,说明竖向调节板的结构及工 作原理。
第一竖板 21包括形状、尺寸规格相同的两条相铰接的支撑杆 21a, 21b, 两支撑杆 21a, 21b相铰接的位置上设置紧固螺栓 3。 由于两支撑杆 21a, 21b 相铰接, 两支撑杆 21a, 21b可以以铰接点 (如图所示紧固螺栓 3的位置) 进行折叠。
两支撑杆 21a, 21b的两个端头分别可转动的固定在第一横板 11和第二 横板 12的端部上。
第二竖板 22是设置与第一竖板 21在形状、规格尺寸上相同的折叠杆结 构, 其同样包括两个相铰接的支撑杆 22a, 22b, 其中, 一个支撑杆 22a的一 端可转动的限位在上述第一横板 11的滑槽 111中, 另一个支撑杆 22b的一 端可转动的限位在上述第二横板 12的滑槽 121中。
装配后, 第一竖板 21的两支撑杆 21a, 21b分别与第二竖板 22的两支 撑杆 22a, 22b相平行。
当第一竖板 21和第二竖板 22进行折叠时, 由于支撑杆 21a, 21b与第 一横板 11和第二横板 12的固定端、 以及支撑杆 22a、 22b与滑槽 111 , 121 可进行相对转动, 该首尾相连的结构能够实现联动。 在此过程中, 第一竖板 21和第二竖板 22可保持同步折叠, 同时, 第一横板 11和第二横板 12也能 够保持相平行的相对位置。
在支撑杆 21a, 21b以及支撑杆 22a、 22b往复折叠的过程中, 可以改变 第一横板 11和第二横板 12间的间距, 也就是第一横板 11和第二横板 12间 的纵向间距。
在第一竖板 21和第二竖板 22上设置紧固螺栓 3的作用是: 当第一横板 11和第二横板 12间的间距调整到合适的位置后, 就可以通过旋拧紧固螺栓 3, 将两支撑杆 21a, 21b以及支撑杆 22a、 22b间的相对折叠角度固定, 进 而实现横向调节板之间间距的固定。
本实施例中, 在支撑杆 21a, 21b以及支撑杆 22a、 22b与第一横板 11 和第二横板 12相连接的端部上设有检测头(图未示 ), 该四个检测头设置在 同一平面上。
本实施例中, 该检测头设置为按压用橡胶头。
第二竖板 22的两端分别可转动的限位在滑槽 111、 121中的作用是: 使第二竖板 22的两相铰接支撑杆 22a, 22b能够沿滑槽 111、 121进行 横向滑动, 这样, 固定在支撑杆 22a、 22b端部上的按压用橡胶头便可同步 横向滑动。 在支撑杆 22a、 22b往复滑动的过程中, 可以改变第一竖板 21和 第二竖板 22之间的横向间距。
综上,通过分别调整两块横向调节板之间的距离和两块纵向调节板之间 的距离调节四个按压用橡胶头的位置,实现按压用橡胶头能够对应 TFT-LCD 的多个区域。
进一步的,还可以在多块横向调节板上或多块纵向调节板上设置把手 4, 用以提起或按压整个装置。
本实施例中, 把手 4设置在第一横板 11和第一竖板 21的连接处。
进一步的, 多块横向调节板或多块纵向调节板使用透光材料制成, 如亚 克力材料。其作用是保证检查装置在按压时能够观察到待检查画面的变化情 况。
具体实施时, 通过旋松紧固螺栓 3, 使位于纵向调节板端部的按压用橡 胶头的位置间隔与 TFT-LCD待检查画面的压力点位置间隔一致, 然后旋拧 紧固螺栓 3, 使所有按压用橡胶头固定。
如图 2所示, 为本发明压力点检查装置第二实施例的结构示意图。
本实施例与实施例一的不同之处在于: 多块横向调节板还包括形状, 尺 寸与第一横板 11形状相同的第三横板 13, 其位于第一横板 11的下方。 第三 横板 13上开设与实施例一中滑槽 111 , 121位置相平行的滑槽 131。
第一竖板 21包括形状、尺寸相同的四条依次相铰接的支撑杆 21a, 21b, 21c和 21d;第二竖板 22包括形状、尺寸相同的四条依次相铰接的支撑杆 22a, 22b, 22c和 22d。 在两竖板 21 , 22与三横板 11 , 12, 13相连接的连接处共 设有六个处于同一平面上的按压用橡胶头,在相邻两支撑杆之间设有紧固螺 栓 3 , 其中:
第一竖板 21的中部, 也就是支撑杆 21b, 21c分别可转动的固定在第一 横板 21上; 第一竖板 21的两端, 也就是支撑杆 21a, 21d的端部可转动的 分别固定在第二横板 12端部和第三横板 13端部。
第二竖板 22的中部, 也就是支撑杆 22b, 22c的相铰接的位置可转动的 限位在第一横板 11的滑槽 111中; 第二竖板 22的两端, 也就是支撑杆 22a, 22d的端部可转动的分别限位在第二横板 12的滑槽 121和第三横板 13的滑 槽 131中。
如图 3所示, 为本发明压力点检查装置第三实施例的结构示意图。
本实施例与实施例一的不同之处在于: 多块竖向调节板还包括形状, 结 构与第一竖板 21相同, 并可进行折叠的第三竖板 23;
第一横板 11在其两侧开设两个滑槽 111 , 112, 第二横板 12在其两侧开 设两个滑槽 121 , 122, 第三竖板 23的两端分别可转动的限位在滑槽 112, 122中。 同时, 在三竖板 21 , 22, 23与两横板 11 , 12相连接的连接处同样 设有六个处于同一平面上的按压用橡胶头。
如图 4所示, 为本发明压力点检查装置第四实施例的结构示意图。
本实施例与实施例三的不同之处在于: 多块横向调节板还包括形状, 尺 寸与第一横板 11形状相同的第三横板 13 , 其位于第一横板 11的下方。 第三 横板 13上开设与实施例三中滑槽 111 , 112位置相平行的滑槽 131 , 132。
本实施例中的三条竖板采用与实施例二中第一竖板相同的结构。 这样, 在三块可折叠的竖板 21 , 22, 23与三块横板 11 , 12, 13相连接的连接处共 装设 9个处于同一平面上的按压用橡胶头。
具体实施时, 某液晶显示基板需要按压检查 9个压力点, 通过该实施方 式的压力点检查装置进行检查, 仅需要费时 1秒。 与手动逐点检查相比, 时 间可以节约 3秒左右, 提升检测效率。
综上,本发明的压力点检查装置可以根据实际的需要设计出不同数量的 按压用橡胶头, 并可根据检查画面的压力点间隔对间距进行调节, 实施对 TFT LCD多个区域上压力点的同步按压检查。
实施本发明的压力点检查装置, 具有如下有益效果: 由于多块横向调节 板之间的纵向间距设置可调, 多块纵向调节板之间的横向间距设置可调, 且 在多块横向调节板和 /或多块纵向调节板上装设有多个检测头;可将压力点检 查装置上的所有检测头同步按压在液晶显示面板的多个压力点上, 用以检查 画面显示情况。 能够节约检查时间, 避免遗漏压力点; 结构设置筒单, 可进 行灵活调节。
以上所揭露的仅为本发明较佳实施例而已, 当然不能以此来限定本发明 之权利范围, 因此等同变化, 仍属本发明所涵盖的范围。
