Description

一种液晶屏检测连接装置 技术领域
本实用新型属于液晶屏生产检测领域，尤其涉及液晶屏的检测设备领域 。
 背景技术
液晶显示屏在方方面面的应用给人们带来了方便实用，由于液晶屏本身所具有的特性，液晶显示屏在生产过程中需要必要的检测步骤以保证其合格率，现有技术中对液晶显示屏的检测工作采用插卡模式进行，所谓插卡模式是将检测设备的连接件设计成插槽式的连接槽，将需检测的液晶显示屏的连接电极插入连接槽中，然后通过检测设备对液晶显示屏进行检测，连接槽中设有与液晶显示屏的连接电极相对应的多个连接弹片，显示屏进入连接槽中，所述连接弹片具有向下的压力，迫使连接弹片分别与连接电极的各个电极点紧密连接，检测完毕之后将液晶显示屏从连接槽中取出，此类检测设备的连接槽具有三个缺点：
1液晶显示屏的连接电极受到至少两次连接弹片的磨损，由于连接电极的镀层很薄，在受磨损后容易脱落，检测时没有问题，但拔出连接电极的时候镀层的脱落容易致使显示屏成为一个标注为合格品的问题显示屏；
2检测过程对连接弹片也会构成磨损，连接弹片上的电极涂层也会在长期使用后发生脱落的现象，容易导致检测结果出现错误，另外也容易发生弹片弹力不足，连接出现虚连同样出现检测结果错误；
3连接槽具有多个连接弹片，其生产成本较高，同时又具有上述第2点的问题，在出现了问题后，其更换成本高，整体会提高液晶显示屏的生产成本。
 技术问题
本实用新型的目的在于提供一种液晶屏检测连接装置，旨在解决现有技术中液晶显示屏的连接电极容易受到检测设备的连接槽磨损的问题。
 技术解决方案

优选地，设一与所述压板相连接的压杆，任意一个所述限位卡档的外侧设有一个固定端，所述压杆一端连接于所述固定端并且可以所述固定端为圆心进行旋转。
优选地，所述压板中心点与所述压杆的中心点活动连接。

 本发明的实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
实施例一，
参照图1和图2所示，本实用新型实施例提供一种液晶屏检测连接装置，包括压板2a和导电胶棒1a，所述导电胶棒1a具有多个可与液晶屏3的连接电极31分别相对应的导电环11a，所述压板2a设于所述导电胶棒1a的上方，依借上述技术方案，本实用新型所提供的液晶屏检测连接装置在使用时，将需要检测的液晶屏3置于工作平台上，所述导电胶棒1a置于所述液晶屏3的连接电极31上方，并且使所述导电环11a与所述连接电极31一一对应，所述导电环11a通过电缆与检测设备连接，所述压板2a对导电胶棒1进行下压，促使所述导电环11a与液晶屏3的连接电极31紧密连接充分接触，能够良好的将检测设备的检测信号通过所述导电环11a输入到液晶屏中从而进行检测，由于导电胶棒1a的本身物理特性，在受到所述压板2a的下压力时，所述导电胶棒1a会发生轻微变形，可保证所述导电环11a与液晶屏3的连接电极31紧密连接充分接触，达到了避免液晶屏3连接电极31被磨损的效果。
参照图3所示，由于所述导电胶棒1a上的导电环11a通过电缆连接到检测设备上，而导电环11a往往采用在导电胶棒1a上缠绕导电丝的方式构成，用电缆连接导电环11a具有一定的难度，所以进一步地将所述压板2a上设有与所述导电环11a相对应的压板导电极21a，所述压板导电极21a通过电缆连接检测设备，而检测设备通过压板导电极21a与所述导电环11a的全面连接向位于所述导电胶棒1a下方的连接电极31传输信号，进行液晶屏3的检测工作。
参照图1所示，所述导电胶棒1a的两边设有可对液晶屏3连接电极31限位的限位卡档12a，所述限位卡档12a的上还设有可方便液晶屏连接电极31置入的导向端121a，方便所述连接电极31的定位，配合所述导电环11a与所述连接电极31准确对应。
参照图1所示，为了方便给所述压板2a施加向下的压力，设一与所述压板2a相连接的压杆6a，任意一个所述限位卡档12a的外侧设有一个固定端7a，所述压杆6a一端连接于所述固定端7a并且可以所述固定端7a为圆心进行旋转，当所述连接电极31就位后，通过所述压杆6a施加压力压迫压板2a向下施压，检测完毕后，抬起所述压杆6a，所述压杆6a一端围绕固定端7a进行最大一百八十度旋转，更方便了检测者的操作工作。
为了能够让所述压杆6a提供给所述压板2a的向下力作用在所述压板2a的中间，使导电胶棒1a均匀受压，将所述压板2a中心点与所述压杆6a的中心点活动连接，所述压板2a的受力点为其中心点，受力更均匀，使所述导电胶棒1a变形更加均匀。
为了在检测过程将所述压杆6a固定在所述压板2a上方并且同时施加向下的压力，与所述固定端7a相对的另一个限位卡档的外侧设有固定扣8a，所述固定扣8a设在工作平台之上，可通过所述固定扣8a将压杆6a的自由端固定，当检测完毕后打开所述固定扣8a，抬起压杆6a，方便将液晶屏3取出，本实施例可以采用活动导电胶棒1a，或者采用将所述限位卡档12a固定于工作台面，将所述导电胶棒1a两端固定在所述限位卡档12a上，所述导电胶棒1a下表面到工作台面的距离小于液晶屏3的连接电极31厚度，每次检测时将连接电极31挤入所述导电胶棒1a与工作台面之间，亦或者将所述导电胶棒1a两端活动固定在所述限位卡档12a上，所述限位卡档12a上设有活动槽，所述导电胶棒1a的两端具有卡轴，所述卡轴活动置入所述限位卡档12a的活动槽中，当将液晶屏3的连接电极31置入限位卡档12a内后，再将所述导电胶棒1a的卡轴置入到限位卡档12a的活动槽中，而所述压杆6a的固定端7a和所述固定扣8a都是固定在所述工作台面上，整体的连接机构制造成本远远低于现有技术中的连接槽，另外也不会发生现有技术中的连接槽内弹片失去弹性或者受到磨损电联失效而导致检测数据出错的现象，更不会发生磨损液晶屏的连接电极的现象。
实施例二，
参照图2和图4所示，本实施例提供一种液晶屏检测连接装置，包括压板2和导电胶棒1，所述导电胶棒1具有多个可与液晶屏3的连接电极31分别相对应的导电环11，所述压板2设于所述导电胶棒1的上方，依借上述技术方案，本实用新型所提供的液晶屏检测连接装置在使用时，将所述导电胶棒1置于工作平台上，然后将所述液晶屏3的连接电极31向下与所述导电胶棒1的导电环11一一对应，所述压板2对所述连接电极31的背面进行下压，迫使所述连接电极31与所述导电环11紧密连接充分接触，能够良好的将检测设备的检测信号通过所述导电环11输入到液晶屏3中从而进行检测，由于导电胶棒1的本身物理特性，在受到所述压板2通过连接电极31向下施加的压力时，所述导电胶棒1会发生轻微变形，可保证所述导电环11与液晶屏3的连接电极31紧密连接充分接触，达到了避免液晶屏3连接电极31被磨损的效果。
由于所述导电胶棒1上的导电环11通过电缆连接到检测设备上，而导电环11往往采用在导电胶棒1上缠绕导电丝的方式构成，用电缆连接导电环11具有一定的难度，所以进一步地，在所述导电胶棒1的下方设有底座5，所述底座5具有与所述导电环11相对应的底座导电极（未示出），所述底座导电极通过电缆连接检测设备，而检测设备通过底座导电极与所述导电环11的全面连接向位于所述导电胶棒1上方的连接电极31传输信号，进行液晶显示屏的检测工作。
所述导电胶棒1的两边设有可对液晶屏3连接电极31限位的限位卡档12，所述限位卡档12的上部设有可方便液晶屏3连接电极31置入的导向端121，方便所述连接电极31的置入和定位，配合所述导电环11与所述连接电极31准确对应。
为了方便给所述压板2施加向下的压力，设一与所述压板2相连接的压杆6，任意一个所述限位卡档的外侧设有一个固定端7，所述压杆6一端连接于所述固定端7并且可以所述固定端7为圆心进行旋转，当所述连接电极31就位后，通过所述压杆6施加压力压迫压板2向下施压，检测完毕后，抬起所述压杆6，所述压杆6一端围绕固定端7进行最大一百八十度旋转，更方便了检测者的操作工作。
为了能够让所述压杆6提供给所述压板2的向下力作用在所述压板2的中间，使导电胶棒1均匀受压，将所述压板2中心点与所述压杆6的中心点活动连接，所述压板2的受力点为其中心点，受力更均匀，使所述导电胶棒1变形更加均匀，为了在检测过程将所述压杆6固定在所述压板2上方并且同时施加向下的压力，与所述固定端7相对的另一个限位卡档的外侧设有固定扣8，可通过所述固定扣8将压杆6的自由端固定，当检测完毕后打开所述固定扣8，抬起压杆6，方便将液晶屏3取出，本实施例可以采用将所述限位卡档12固定于所述底座5上，每次检测时将连接电极31置入所述限位卡档12之间，而所述压杆6的固定端7和所述固定扣8可以采用固定在工作台面上或者是固定在所述底座5上，整体的连接机构制造成本远远低于现有技术中的连接槽，另外也不会发生现有技术中的连接槽内弹片失去弹性或者受到磨损电联失效而导致检测数据出错的现象，更不会发生磨损液晶屏的连接电极的现象。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
