( 1 ) 首先将液晶面板 2放置于支撑平台 3上, 参见图 5a;
( 2 ) 由伺服电机 4控制夹持机构 1的第一夹持臂 10a和第二夹持臂 10b相 对所述固定轴 20旋转, 使所述第一夹持臂 10a和第二夹持臂 10b相对抵近, 从 而使所述夹持部 102通过机械力夹持液晶面板 2, 参见图 5b;
( 3 )控制所述真空控制装置 5通过夹持部 102上的真空孔 103抽真空吸附 所述液晶面板 2, 提高夹持臂的夹持力;
(4)对液晶面板进行切割和裂片之后, 在所述夹持机构 1夹持液晶面板的 位置形成面板残材 201,通过所述夹持机构 1牵引使所述面板残材 201脱离所述 液晶面板 2, 参见图 5c。
( 5 ) 由夹持机构 1将所述面板残材 201传送至残材区域 6, 由真空控制装 置 5和伺服电机 4控制松开夹持机构 1的两个夹持臂 10a、 10b,使面板残材 201 脱落于残材区域 6中, 参见图 5d。 综上所述, 本发明提供的夹持机构, 在夹持部设置有真空孔, 在夹持液晶 面板时, 由真空控制装置通过真空孔抽真空吸附液晶面板, 提高夹持臂的夹持 力度和用力的均一性, 特别是对于厚度较薄的液晶面板残材具有良好的夹持效 果; 在一些优选的方案中, 本发明的夹持装置由伺服电机控制第一夹持臂和第 二夹持臂相对活动, 在液晶面板切割机安装有多个夹持机构时, 多个夹持机构 具有良好的同歩性; 在一些优选的方案中, 本发明增加了夹持部的长度和宽度, 增大了夹持机构的夹取量, 对于宽度较宽的液晶面板残材具有更好的夹持效果, 保证切割后的较宽的残材顺利的牵引脱离液晶面板, 提高工作效率, 节省作业 成本。 需要说明的是, 在本文中, 诸如第一和第二等之类的关系术语仅仅用来将 一个实体或者操作与另一个实体或操作区分开来, 而不一定要求或者暗示这些 实体或操作之间存在任何这种实际的关系或者顺序。 而且, 术语 "包括"、 "包 含"或者其任何其他变体意在涵盖非排他性的包含, 从而使得包括一系列要素 的过程、 方法、 物品或者设备不仅包括那些要素, 而且还包括没有明确列出的 其他要素, 或者是还包括为这种过程、 方法、 物品或者设备所固有的要素。 在 没有更多限制的情况下, 由语句 "包括一个…… " 限定的要素, 并不排除在包 括所述要素的过程、 方法、 物品或者设备中还存在另外的相同要素。
