Description

技术领域
本发明涉及液晶显示技术领域，特别涉及一种异向导电膜拉伸夹取装置及其夹取滚筒和夹取头。

在液晶面板的覆膜封装技术中，为了搭载电子组件，需要在面板、覆晶薄膜（Chip On Flex，COF）和印刷电路板装配（Printed Circuit Board Assembly，PCBA）的基板上贴附异向导电膜（Anisotropic Conductive Film，ACF），通常采用如图1所示的ACF附着系统，其基本原理为，异向导电膜拉伸夹取装置10中的夹取滚筒11与夹取头12配合夹取纸带13，拉伸夹取装置10的气缸14控制夹取移动路径，进而控制纸带13的行走长度；在纸带13行走过程中，ACF供给滚筒15将ACF叠置于纸带13的剥离层上；当到达指定长度时，切割刀16阻断ACF；当拉伸夹取装置10停止夹取时，纸带13停止行走，压接头17下压，使ACF贴附于位于压接头17下方的基板（图中未示出）上，且贴附的ACF长度为指定长度；拉伸夹取装置10继续夹取纸带13，直至纸带13回到回收部件18内。目前，传统的夹取滚筒11采用树脂材料，其形状为圆柱体状；夹取头12采用不锈钢材料，其形状为棱锥状。但是，在高频率夹取使用过程中，由于夹取滚筒11磨损较大，摩擦系数下降，造成夹取叠置有异向导电膜的纸带13时打滑，拉出的异向导电膜长度不符合产品制程规格，从而导致异向导电膜贴附不良及压痕不良，产品重工和设备宕机损失，严重影响产品的品质良率和设备的稼动率，以致产品的制造成本升高。

附图说明
图1为现有技术中的异向导电膜拉伸夹取装置的结构示意图；
图2为本发明异向导电膜拉伸夹取装置的第一实施例的结构示意图；
图3为本发明异向导电膜拉伸夹取装置的第二实施例的结构示意图。
本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图2所示，图2为本发明异向导电膜拉伸夹取装置的第一实施例的结构示意图，该实施例提出的夹取滚筒21，与夹取头22配合完成异向导电膜的定位和压接，夹取滚筒21呈正棱柱状，例如，呈正八棱柱状或正六棱柱状，本实施例以夹取滚筒21呈正八棱柱状为例，呈正八棱柱状的夹取滚筒21的一侧表面对应于夹取头22的前端，夹取头22的与前端相对的一端连接一伸缩装置24，伸缩装置24使夹取头22朝夹取滚筒21运动，或使夹取头22背离夹取滚筒21运动。
在初始位置，伸缩装置24带动夹取头22朝夹取滚筒21运动，叠置有异向导电膜的纸带23被加紧在夹取滚筒21与夹取头22之间，气缸25控制夹取滚筒21与夹取头22向回收部件26方向运动，带动纸带23移动，同时，ACF供给滚筒27将ACF叠置于纸带23的剥离层上，即实现ACF的拉伸；当ACF的拉伸长度达到指定长度时，切割刀28阻断ACF；当叠置有指定长度ACF的一段纸带23到达基板（图中未示出）待贴附位置上方时，夹取滚筒21与夹取头22停止移位，压接头29下压纸带23，使ACF贴附于位于压接头29下方的基板（图中未示出）上，且贴附的ACF长度为指定长度；夹取滚筒21与夹取头22继续向回收部件26方向运动，到达回收部件26前端的终止位置，纸带23回到回收部件26内，伸缩装置24带动夹取头22背离夹取滚筒21运动，放开纸带23，气缸25控制夹取滚筒21与夹取头22向背离回收部件26方向运动，回到初始位置。
由于采用了正棱柱结构的夹取滚筒21，在拉伸夹取叠置有异向导电膜的纸带23时，使夹取滚筒21的一侧面与叠置有异向导电膜的纸带23接触，相较于传统的圆柱体结构的夹取滚筒，增加了夹取滚筒21与叠置有异向导电膜的纸带23的接触面积，增加了夹取滚筒21的摩擦系数，避免夹取打滑的情况发生，使拉出的异向导电膜长度符合产品制程规格，拉伸夹取精度和稳定性得到改善，有效提高异向导电膜的贴附良率，降低生产成本。另外，还可在夹取滚筒21的各侧面贴附铁氟龙薄膜，进一步增加夹取滚筒21的摩擦系数。为了提高夹取滚筒21的耐磨性，还可采用不锈钢材质制作夹取滚筒21。
此外，夹取滚筒21沿其转动轴可转动，可预先设定夹取次数阈值，当夹取次数达到夹取次数阈值时，夹取滚筒21自动转动一角度，或者采用手动的方式转动夹取滚筒21的角度，使正棱柱的另一侧面切换至与夹取头22对应，由于拉伸夹取操作并非始终在夹取滚筒21的一个侧面，通过定时切换夹取滚筒21与叠置有异向导电膜的纸带23的接触面，有利于减少对夹取滚筒21的磨损。
如图3所示，图3为本发明异向导电膜拉伸夹取装置的第二实施例的结构示意图，该实施例提出的夹取头32，与夹取滚筒31配合，夹取滚筒31的结构可参照图2所示实施例中的夹取滚筒结构，在此不作赘述。本实施例的夹取头32可呈长方体状或圆柱体状，当夹取头32呈长方体状时，长方体的与夹取滚筒31的表面相对应的一端面作为夹取头32的前端；当夹取头32呈圆柱体状时，圆柱体的一端面与夹取滚筒31的表面相对应，作为夹取头32的前端。由于采用了长方体结构或圆柱体结构的夹取头32，在夹取叠置有异向导电膜的纸带33时，使长方体或圆柱体的端面与叠置有异向导电膜的纸带33接触，相较于传统的三棱柱结构的夹取头，增加了夹取头32与叠置有异向导电膜的纸带33的接触面积，增加了夹取头32的摩擦系数，避免夹取打滑的情况发生，使拉出的异向导电膜长度符合产品制程规格，拉伸夹取精度和稳定性得到改善，有效提高异向导电膜的贴附良率，降低生产成本。此外，可将夹取头32的前端的端面设计为粗糙表面，例如，在夹取头32的前端的端面上设置多个条纹凹槽，进一步增加夹取头32与叠置有异向导电膜的纸带33的摩擦系数，避免打滑。
本实施例还提出一种异向导电膜拉伸夹取装置，包括夹取滚筒和夹取头，其中，夹取滚筒的结构可参照图2或图3所示实施例中的夹取滚筒结构，夹取头的结构可参照图2或图3所示实施例中的夹取头结构，在此不作赘述。由于采用了前述实施例的结构，本实施例中异向导电膜拉伸夹取装置相较于传统的异向导电膜拉伸夹取装置来讲，可有效提高拉伸夹取装置与叠置有异向导电膜的纸带23之间的摩擦系数，避免夹取打滑的情况发生，使拉出的异向导电膜长度符合产品制程规格，拉伸夹取精度和稳定性得到改善，有效提高异向导电膜的贴附良率，降低生产成本。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
