Description

针头清洁装置及带该装置的框胶涂布机
Figure imgf000002_0001
现今科技蓬勃发展， 信息商品种类推陈出新， 满足了大众不同的需 求。 早期显示器多半为阴极射线管 （Cathode Ray Tube, CRT )显示器， 由 于其体积庞大与耗电量大， 而且所产生的辐射对于长时间使用显示器的使 用者而言， 有危害身体的问题。 因此， 现今市面上的显示器渐渐将由液晶 显示器 ( Liquid Crystal Display , LCD )取代 i日有的 CRT显示器。
液晶显示器具有机身薄、 省电、 无辐射等众多优点， 得到了广泛的应 用。 现有市场上的液晶显示器大部分为背光型液晶显示器， 其包括壳体、 设于壳体内的液晶显示面板及设于壳体内并相对液晶显示面板设置的背光 模组（backlight module ) 。 液晶显示面板的工作原理是在两片平行的玻璃 基板当中放置液晶分子， 并在两玻璃基板上施加驱动电压来控制液晶分子 的旋转， 从而将背光模组的光线折射出来产生画面。
目前液晶显示面板制造技术日益成熟， 液晶显示面板的生产需要经过 "前段阵列 （Ai'ray )制程、 中段成盒（ Ceii )制程、 后段模组组装" 三个 复杂的过程。 先分别制作有图形的有源阵列基板 ( TFT基板） 与彩色滤光 片基板（CF基板） ， 并将两者在液晶滴注 ( One Drop Filling, ODF )制程 中进行贴合。 在两片基板相应的位置上涂布边框胶， 并在涂布好边框胶的 有源阵列基板上的边框胶内注入液晶材料， 将两基板贴合， 并在加热作用 的同时釆用 UV光照射边框胶， 从而使得边框胶固化， 进而密封住液晶材 料。
涂布边框胶一般使用框胶涂布机来完成， 框胶涂布机针头在对一定数 量的基板完成涂胶后， 容易在针头位置产生胶材的堆积， 如图 1 所示， 图 中示出了： 针管 100, 针头 200， 及堆积的胶材 300， 该堆积的胶材 300会 造成以下影响：
a、 框胶涂布机涂布边框胶的过程中出现异常， 产生缺口 （gap ) ， 机 台停止， 用无尘布擦拭针头 200后再进行涂布， 间断地完成涂布动作会影 响产品品质。 b > 框胶涂布机针头 200运动过程中会因加速减速而使得堆积的胶材 300掉落在液晶显示面板的显示区内， 造成产品报废。
c、 清洁框胶涂布机针头 200 时需打开设备门， 人工使用无尘布擦拭 针头 200， 增加产品粒子问题（ particle issue ) 的风险。 发明内容
本发明的目的在于提供一种针头清洁装置， 可根据设定自动清洁针 头， 无需人工清洁， 提高工作效率。
本发明的另一目的在于提供一种带针头清洁装置的框胶涂布机， 可根 据设定自动清洁涂胶组件的针头， 无需人工清洁， 提高工作效率的同时， 减少打开设备门清洁针头带来的粒子问题， 减少框胶涂布机针头上的堆积 的胶材对产品造成的不良影响。
为实现上述目的， 本发明提供一种针头清洁装置， 包括： 相对设置的 两导轨、 分别可滑动安装于两导轨上的两支撑杆 , 分别固定连接所述两支 撑杆的两马达。 以及分别安装于两支撑杆上且相对设置的两挡片， 所述两 挡片相对两侧面分别对应设置一凹部， 所述支撑杆在马达的驱动下沿着导 轨来回运动， 带动两档片相互靠近或背离， 进而使两凹部闭合形成一通孔 或打开， 在所述两凹部打开时， 待清洁的针头移动到两凹部之间 , 接着两 档片在在两马达的驱动下相互靠近移动， 直至将待清洁的针头收容于所述 两凹部形成的通孔内， 然后待清洁的针头沿通孔轴线向外移动， 在待清洁 的针头向外移动的过程中， 所述档片刮掉待清洁的针头上的积胶， 完成对 待清洁的针头的清洁动作。
