本发明实施例提供了一种显示模组端子清洗装置，其能克服现有显示模组端子清洗装置中存在的技术缺陷，从而进一步提升对显示模组端子的清洗效果。此外，该显示模组端子清洗装置结构简单，未额外增加费用，成本较低。以下分别进行详细说明。
请参阅图1，图1为本发明实施例提供的显示模组端子清洗装置的正面结构示意图。本发明的显示模组端子清洗装置100用以对显示模组200的端子区域210进行清洗，该显示模组端子清洗装置100包括吹气组件10以及擦拭组件30。其中，所述吹气组件10用以将所述端子区域210上颗粒状异物(例如颗粒状的无机异物)吹走，以对所述显示模组200上的杂物进行清理。所述擦拭组件30用以清除所述端子区域210上残留的其它异物(例如残胶等有机异物)。进一步地，所述擦拭组件30是在吹气组件10作业后再执行操作，确保擦拭过程中所述端子区域210没有颗粒状异物，进一步增加对显示模组端子的清洗效果，即可防止在擦拭过程中带动端子区域210上的颗粒状异物刮伤端子下方的衬底基板。传统的擦拭布+溶剂的清洁方式由于无法提前清除大颗粒无机异物(如粉尘颗粒)而容易造成OLED的柔性衬底划伤；而超声波水洗的清洗方式又由于无法彻底清除粘胶等有机异物以及端子背面的异物，容易出现压着异物及基板崩裂导致产生不良品。
本实施例提供的显示模组端子清洗装置，先通过所述吹气组件10吹扫掉端子区域210上的粉尘等颗粒状异物(例如颗粒状的无机异物)，再通过所述擦拭组件30擦拭端子区域210，能有效清除该端子区域210上残留的其它异物(例如残胶等有机异物)的同时，不会再由于颗粒状异物的存在而划伤该端子区域210的衬底基板。显然，本发明的显示模组端子清洗装置不仅能保证良好的清洗效果，还能确保安全清洗而不会损伤显示模组。
在本发明一实施方式中，所述吹气组件10为一干净干燥空气(Clean Dry Air，CDA)模组，其可提供高压并且干燥、干净的气体，以通过所提供的干燥、干净的高压气体吹去所述端子区域210上的颗粒状异物，防止后续所述擦拭组件30擦拭所述端子区域210时，所述擦拭组件30摩擦所述颗粒状的无机异物而刮伤所述端子区域210的衬底基板。在本发明的实施例中，所述吹气组件10包括送气管道11以及气泵(图未示)，所述送气管道11与所述气泵相连，用以将所述气泵产生的高压气体输出至所述端子区域210的表面，即该送气管道11输出的高压气流可吹走所述端子区域210表面的颗粒状异物。
在本发明一实施方式中，所述吹气组件10直接固定至对准所述显示模组200的端子区域210的位置。在本发明另一实施方式中，所述吹气组件10还可通过一可移动的固定座固定后，再通过该固定座将所述吹气组件10调节至对准所述端子区域210的位置。
在本发明一实施方式中，所述擦拭组件30配合清洗溶剂来清除所述端子区域210上残留的其它异物(例如残胶等有机异物)。
在本发明一实施方式中，所述清洗溶剂包括以下中的至少一种：酒精、丙醇、异丙胺等，并且本发明中不对所述清洗溶剂做具体限定，可根据所述端子区域210上残留的异物来选取一种或多种对应的清洗溶剂。
在本发明一实施方式中，所述擦拭组件30包括至少两个擦头31、设置在所述擦头31上的出液通道33以及包覆在所述擦头31末端的擦拭布(图未示)。所述出液通道33连接至清洗溶剂供应部(图未示)，用以输出清洗溶剂至所述擦拭布上。至少两个所述擦头31在平行于所述所述端子区域210的方向相对间隔设置，即，至少两个所述擦头31分别排列在所述端子区域210的相对两侧，且位于该端子区域210一侧排列的擦头31与位于该端子区域210另一 侧排列的擦头31相对间隔设置，进一步地，位于所述端子区域210相对两侧的擦头31在位置上一一对应，使得该擦头31上包覆的擦拭布相正对，用以分别接触并抵持夹设于两个擦头31中间的端子区域210的相对表面，即可通过包覆于所述擦头31上的擦拭布同时擦拭所述端子区域210的两相对表面。
在本发明一实施方式中，所述擦头31大致呈圆柱体状，其末端为一擦拭平面311，所述擦拭布包覆所述擦拭平面311，所述擦头31即可通过擦拭平面311带动擦拭布清洗与所述擦拭平面311相接触的端子区域210。
在本发明一实施方式中，所述出液通道33贯穿设置在所述擦头31内，其一端连接至清洗溶剂供应部，另一端贯穿所述擦拭平面311，用以输出清洗溶剂至包覆在所述擦拭平面311上的擦拭布，使擦拭布上能浸透清洗溶剂而增强清洁效果。在本发明的其他实施例中，所述出液通道33不限于设置在所述擦头31内，也可以设置于所述擦头31的侧面，本发明也不对所述出液通道33与所述擦头31之间的相对位置做具体限定，只要能通过所述出液通道33将清洗溶剂输出至所述擦拭布上，能浸湿所述擦拭布进行后续的擦拭操作即可。
进一步的，所述出液通道33呈“L”字形，其一端贯穿所述擦头31的侧面，以方便连接清洗溶剂供应部，另一端贯穿所述擦拭平面311，以方便将清洗溶剂输出至所述擦拭平面311上的擦拭布上。可以理解的是，可以将所述出液通道33设置为一个，也可以设置为多个，以增强对所述擦拭布的供液能力。
在本发明一实施方式中，为了获得更好的清洗效果，可以对应每一擦拭组件30分别设置至少一吹气组件10，但本发明中不对所述吹气组件10的数量做具体限定，也可以仅设置一个吹气组件10，也可以对应一个擦拭组件30设置多个吹气组件10，只要能确保通过所述擦拭组件30擦拭所述端子区域210时，所述吹气组件10已经将端子区域210上颗粒状异物清除即可。
在本发明一实施方式中，所述送气管道11也内置于所述擦头31内，其结构与所述出液通道33相似，其一端贯穿所述擦头31的侧面并连接至所述气泵，另一端贯穿所述擦拭平面311，以将气泵产生的干净、清洁的高压气体从所述擦拭平面311输出，则该送气管道11输出的高压气流可吹走与所述擦拭平面311相对的所述端子区域210表面的颗粒状无机异物。
可以理解的是，所述送气管道11不限于内置于所述擦头31内，也可以固 定在所述擦头31侧壁上。本发明中，不对所述送气管道11与擦头31之间的相对位置做具体限定，只要所述送气管道11能在所述擦拭组件30擦拭所述端子区域210之前，清除所述端子区域210表面的颗粒状异物即可。
在本发明一实施方式中，所述显示模组端子清洗装置还包括安装部(图未示)，用以实现所述擦拭组件30的安装固定，并带动所述擦拭组件30相对所述端子区域210移动，即可擦洗与所述擦拭组件30相接触的端子区域210。
在本发明一实施方式中，所述显示模组端子清洗装置还包括承载部(图未示)，用以承载待清洗的显示模组，并可带动所述显示模组相对所述擦拭组件30和/或所述吹气组件10移动，即可通过所述吹气组件10与所述擦拭组件30清除所述端子区域210表面的异物。
请一并参阅图2，图2为使用图1所示显示模组端子清洗装置来清洗显示模组的端子区域的清洗方法流程图。本发明的清洗方法包括以下步骤：
S1：将待清洗的显示模组固定至所述显示模组端子清洗装置上。
S2：调节所述端子区域210在所述显示模组端子清洗装置上的位置，使所述擦拭组件30以及所述吹气组件10均对准所述端子区域210。
具体的，调节所述端子区域210相对所述吹气组件10与所述擦拭组件30的位置，使所述送气管道11的出气口以及所述擦头31均对准所述端子区域210，并且所述擦头31上的擦拭布抵持于所述端子区域210的表面。其中，当所述端子区域210的尺寸较大，需要控制所述吹气组件10与擦拭组件30相对所述端子区域210移动才能完成整个端子区域210的清洗时，则沿清洗方向(图1中箭头所指方向，即所述吹气组件10与擦拭组件30相对所述端子区域210移动的方向)设置所述吹气组件10在前、所述擦拭组件30在后，后续通过该显示模组端子清洗装置清洗所述端子区域210时，即可先通过所述吹气组件10清除所述端子区域210的颗粒状异物后，再通过所述擦拭组件30擦拭所述端子区域210残留的其它异物(例如残胶等有机异物)。
S3：控制所述吹气组件吹走所述端子区域上的颗粒状异物。
S4：控制所述擦拭组件清除所述端子区域残留的其他异物。
具体的，先控制所述吹气组件10通过送气管道11输出高压、干净、干燥的气流至所述端子区域210表面，以去除表面的颗粒状异物后，再启动所述擦 拭组件30擦拭相抵持的所述端子区域210表面，即可通过浸透有清洗溶剂的擦拭布将所述端子区域210表面残留的其它异物(例如残胶等有机异物)擦除。当所述端子区域210的尺寸较大时，则控制所述吹气组件10与擦拭组件30相对所述端子区域210移动，并在移动的过程中先通过所述吹气组件10吹走表面的颗粒异物，再通过所述擦拭组件30擦拭表面残留的异物，即可完成所述端子区域210的清洗。
本发明的显示模组端子清洗装置及其清洗方法，先通过所述吹气组件10产生的高压气体吹走所述端子区域210表面的颗粒状异物后，再通过所述擦拭组件30配合清洗溶剂来擦除所述端子区域210上残留的异物，不仅能使清洗后的端子区域210表面的水滴角度达到小于15°的清洁效果，还能规避在清洗过程中刮伤显示模组的问题。
