本实施例中,静电消除装置 6设置在每个棚位上述 B端侧上、 下棚位支 架 41的中部, 且与上下棚位支架 41相垂直。 静电消除装置 6能够以其两端 为轴自由转动, 其转动结构下述说明。
实施时, 堆垛机的起重机 1利用货叉 2的机械手向棚位 4放入或取出卡 匣 3 ,静电消除装置 6能够吹出带电离子风,在第一风机过滤装置 51吹出气 流的作用下, 离子风从 B端侧向卡匣 3进出棚位 4方向的 F侧端飘散,从而 达到消除卡匣内玻璃基板的静电, 提高产品良率的作用。
其中一组风机过滤装置, 也就是第二风机过滤装置 52装设在堆垛机的 天花板 8上, 第二风机过滤装置 52由天花板 8向下吹出气流, 与由第一风 机过滤装置 51吹出的气流在 F侧端的一侧汇合, 并使静电消除装置 6吹出 的离子风产生定向流动。
为加强离子风定向流动的效果,本实施例在与卡匣 3进出棚位 4的 F端 侧不远处设置另一组风机过滤装置 53 , 其采用立式的结构, 且能够朝向 F 端侧吹出气流。 这样, 三组风机过滤装置吹出的气流在距离 F侧端的不远处 进行汇合, 然后由储位墙的底部排出, 起到增强离子风消除卡匣及其内部玻 璃基板静电的作用。
静电消除装置 6设置在每个棚位 4上述 B端侧的作用是:将其装设在第 一风机过滤装置 51的前端, 紧邻第一风机过滤装置 51出风气流的位置。 这 样, 由静电消除装置 6吹出的离子风, 可随风机过滤装置产生的气流发生定 向流动, 使其能够飘散到卡匣 3及玻璃基板表面的各个角落, 提升静电消除 效率, 避免死角。
结合参见图 4所示, 为本发明静电消除装置的立体结构示意图, 静电消 除装置 6 包括可产生带电离子的方块状盒体 60, 其表面开设有长条形狭缝 61。 盒体 60内产生的带电离子可经由长条形狭缝 61吹出。
在盒体 60中贯穿设置有转轴 62, 该转轴 62与盒体 60固定连接, 其两 端分别延伸出盒体 60的顶面和底面, 与上、 下棚位支架 41旋转固定。 在盒 体 60顶面上, 一个驱动装置(图 3未示出)通过皮带轮 63与转轴 62相套 接, 进而可以通过传动皮带调整转轴 62的旋转方向。
实施时, 转轴 62旋转, 盒体 60即可相对所在的棚位支架 41 自由旋转, 扩大了带电离子的到达范围, 能够更大角度地清除玻璃基板上的静电。
请参照图 5所示, 为静电消除装置的内部结构示意图。 盒体 60内与转 轴 62平行设置有用于进风的竖管 64,在竖管 64的高度方向上设置有水平横 板 65。 水平横板 65上竖直设置离子发生器 66, 用以产生并释放带电离子, 在本实施例中该离子发生器 66为放电针。 与放电针 66的高度相适应, 在竖 管 64上还设有吹气装置 68,用以将带电离子经由长条形狭缝 61吹出方块状 盒体 60外, 在本实施例中该吹气装置 66为吹风器。 电源线 67分别与竖管 64和水平横板 65相连, 以分别为吹风器 66和放电针 68提供电能。 转轴 62 与皮带轮 63相套接, 在皮带轮 63上设置有驱动装置 69, 该驱动装置 69在 本实施例中为伺服电机。 进一步的, 堆垛机还包括用以控制静电消除装置自由转动角度的控制器
7, 该控制器 7与伺服电机相连, 其通过控制伺服电机使转轴 62在 0°-180° 之间自由旋转。
为本发明静电消除装置在具体使用时, 如图 6所示。 伺服电机 69接收 到控制器 7旋转角度的转动信号后, 将驱动皮带轮 63转动, 通过传动皮带 调整转轴 62的旋转方向。 由于转轴 62与方块状盒体 60为固定连接, 因此 也带动整个静电消除装置 6随着卡匣 3的进出在一定角度内旋转, 具体可以 是 30。、 90。、 150。或者 180。。
与此同时, 电源线 67接通, 竖管 64中通入压缩空气的从吹风器 68中 吹出, 将放电针 66生成的带电离子经由长条形狭缝 61吹向卡匣。 由于静电 消除装置 6装设在第一风机过滤装置 51的前端, 紧邻第一风机过滤装置 51 出风气流的位置。 这样, 由静电消除装置 6吹出的离子风, 可随风机过滤装 置产生的气流发生定向流动,使其能够飘散到卡匣 3及玻璃基板表面的各个 角落。
此外, 由于卡匣 3设为多层结构, 在竖管 64的高度方向上还可间隔设 置多层水平横板 65 ,这样,每层水平横板 65上放电针 66所产生的带电离子 可以对应吹向卡匣内每层的玻璃基板, 提高了清除静电的效率。
由于静电消除装置 6设置的位置刚好位于风机过滤装置 51的前端, 离 子风能够在定向流动气流的作用下进行静电消除,可以相应地减少安装静电 消除装置 6的个数。 也就是说, 可以仅在每个棚位 B端侧的棚位支架 41上 安装一个静电消除装置 6, 就可以达到在每个棚位两侧的上、 下棚位支架 41 上各安装有一个静电消除装置 6的消除静电的效果, 从而降低设备成本。
本发明静电消除装置的其它实施方式中, 静电消除装置 6两端转轴 62 安装的位置可以根据卡匣 3中放置夜晶玻璃的方式进行调整, 例如, 其也可 以装设在每个棚位 B侧端左、 右棚位支架 41上, 并不影响实施的效果。
此外, 还可以根据对离子风定向流动路径的需求, 仅设置上述第一风机 过滤装置 51或第一风机过滤装置 51和第二风机过滤装置 52,均能够达到使 静电消除装置 6吹出的离子风随风机过滤装置产生气流, 飘散到卡匣 3及玻 璃基板表面各个角落的目的。 本发明实施例分别公开了一种堆垛机和静电消除装置,其具有如下有益 效果: 由静电消除装置吹出的离子风, 可随风机过滤装置产生的气流发生定 向流动, 使能够飘散到卡匣及玻璃基板表面的各个角落, 有效消除玻璃基板 上的静电, 产品良率显著提升。 静电消除装置可以在控制器的控制下做
0。-180。的旋转运动并喷洒带电离子, 不会存在盲点与死角, 能够显著提升消 除卡匣及其中玻璃基板表面静电的效率, 且能够降低设备成本。
以上所揭露的仅为本发明较佳实施例而已, 当然不能以此来限定本发明 之权利范围, 因此等同变化, 仍属本发明所涵盖的范围。
