Description

如图 1 所示， 现有滚轮宽度 D 通常为 10mm , 滚轮间的间距为 190mm〜245mm, 设计简单， 轻便。 但因其滚轮本身宽度小， 玻璃基板传输 时滚轮与之的接触面积也小，几乎是线接触； 另夕卜，滚轮与滚轮的间距较大， 高世代的玻璃基板传输时所承受的应力相应的集中于与滚轮所接触的几条 线上， 导致因应力造成玻璃基板的局部带状色差问题（Mura问题）， 如此对 于玻璃基板品质的伤害较为严重， 甚至会造成整个玻璃基板报废。
发明内容

本发明所提供的滚轮及玻璃基板传输装置， 由于对滚轮进行了加宽设 计， 采用了緩冲性能更好的材料， 当用于玻璃基板传输时， 滚轮与玻璃基板 的接触面积增大， 并且缩小了滚轮的间距， 使得玻璃基板传送平稳， 应力平 均， 减少了对基板结构的损伤， 避免出现 Mura问题， 提升了玻璃基板等级 和品质。
附图说明 为了更清楚地说明本发明实施例或现有技术中的技术方案， 下面将对实 施例或现有技术描述中所需要使用的附图作简单地介绍， 显而易见地， 下面 描述中的附图仅仅是本发明的一些实施例， 对于本领域普通技术人员来讲， 在不付出创造性劳动的前提下， 还可以根据这些附图获得其他的附图。
图 1是现有滚轮的结构示意图。
图 2是本发明实施例——种用于玻璃基板传输的滚轮的立体结构示意 图。
图 3是本发明实施例——种用于玻璃基板传输的滚轮的侧面剖视图。 图 4是本发明实施例二一种玻璃基板传输装置的俯视示意图。
图 5是本发明实施例二一种玻璃基板传输装置的侧视示意图。
具体实施方式
下面参考附图对本发明的优选实施例进行描述。
请参照图 2所示，本发明实施例一提供一种用于玻璃基板传输的滚轮 1 , 包括圓柱形本体 10和包覆在本体 10侧面上的外层 11。 本体 10的轴心处设 有贯穿其顶面和底面的轴孔 12, 用于与滚轮轴 2 (参见图 4所示）装配。
本实施例对滚轮 1 的宽度进行了加宽设计， 将其宽度增加到 100〜120mm。 需要说明的是， 由于滚轮 1的本体 10为圓柱形， 滚轮 1的宽 度在本实施例中是指本体 10的顶面与底面的距离， 即圓柱的侧面长度， 如 图 3所示的 W。 图 3为滚轮 1的侧面剖视图。 本实施例中， W=100mm, 而 聚氨酯涂层 11的厚度 T=5mm。 对于本实施例中滚轮 1的宽度 W的选择， 系基于以下几个因素： 首先， 由于现有滚轮的宽度只有 10mm, 玻璃基板传 输时滚轮与之的接触面积较小， 因此本实施例需要加宽滚轮 1 的宽度， W>10mm ; 第二， 所传输的玻璃基板尺寸通常为 2200x2500mm , 因此 W<200mm; 第三， 滚轮也并非越宽越好， 如果滚轮过于宽大， 则整个玻璃 基板传输装置的重量增加， 由此可能增加驱动负担； 所以综合考虑， 并经实 际测试， 滚轮 1的宽度 W在 100〜120mm范围内是合适的。
本体 10采用铸型尼龙（MC Nylon )制成， 铸型尼龙具有良好的耐磨性 和自润滑性， 噪音低， 机械性能也较好。 外层 11 为聚氨酯涂层（Urethane Coating ), 聚氨酯有较高的机械强度、 卓越的耐磨性以及抗压缩性。 采用新 材料制成的滚轮 1具有良好的防冲击和緩冲效能。
本发明实施例一的滚轮系用于玻璃基板传输，据此本发明实施例二提供 一种玻璃基板传输装置， 如图 4所示， 包括相互平行且间隔设置的至少两根 转轴 2, 每一转轴 2上均共轴套设有至少两个滚轮 1 , 具体地， 转轴 2穿过 各滚轮上轴孔 12, 并通过固定轴环 ( Set Collar ) 20实现与滚轮 1的装配； 以及设置在转轴 2和滚轮 1下方的可升降平台 3。 其中， 滚轮 1的结构、 材 料等与实施例一相同， 此处不再贅述。 当然， 为保证玻璃基板 4顺利传输， 各滚轮 1的顶点需位于同一平面， 玻璃基板 4在该平面上传输。
再结合图 5所示，可升降平台 3包括多根支撑杆 30, 当上游机械手臂实 施放片操作时， 可升降平台 3升起， 支撑杆 30撑起玻璃基板 4, 然后可升降 平台 3下降， 玻璃基板 4放置于滚轮上进行传输； 当玻璃基板 4传输到下游 位置时， 可升降平台 3升起， 支撑杆 30撑起玻璃基板 4, 下游机械手臂实施 取片操作。 由于本实施例的滚轮 1 进行了加宽设计， 宽度为 100〜120mm, 为了避免可升降平台 3升降过程中滚轮 1与支撑杆 30发生干涉， 支撑杆 30 需设置在转轴与转轴之间以及滚轮与滚轮之间的空隙。 优选地， 支撑杆 30 可分为多组， 每组设置在相邻转轴 2之间， 同一组的支撑杆 30相互对齐并 呈直线排列。
另外， 为了克服现有同一转轴上滚轮之间间距较大而导致应力集中的缺 陷， 本实施例调小了同一转轴上滚轮的间距， 同时由于本实施例的滚轮相较 于现有滚轮变得更为宽大， 如果间距过小， 将不利于支撑杆 30的设置。 经 过实际测试， 本实施例中， 同一转轴上滚轮的间距设置为 25mm〜150mm是 合适的。
现有玻璃基板传输装置由于所采用的滚轮宽度小、 间距大， 传输过程中 玻璃基板会发生震动， 导致传输后有精度差异， 需要通过整列机构来进行精 度定位。 而本实施例的传输装置， 所用滚轮宽度增加， 滚轮与玻璃基板接触 面积增大， 并且采用了緩冲效能较高的材料， 使滚轮与玻璃基板之间的摩擦 力增加， 外围的整列机构可能无法推动玻璃基板进行定位。 而且， 如果强行 使用外围的整列机构进行机械定位，可能会由于摩擦力过大而导致玻璃基板 破损。 所以， 本实施例中并不采用外围整列机构来进行定位， 而是通过滚轮 的速度以及水平搭配来进行调整即可达到原有的精度水准， 稳定性较好。 实 际测试的运行效果显示玻璃基板传输稳定， 无震动以及跳动等现象。
本发明实施例提供的滚轮及玻璃基板传输装置， 由于对滚轮进行了加宽 设计， 采用了緩冲性能更好的材料， 当用于玻璃基板传输时， 滚轮与玻璃基 板的接触面积增大， 并且缩小了滚轮的间距， 使得玻璃基板传送平稳， 应力 平均， 减少了对基板结构的损伤， 避免出现 Mura问题， 提升了玻璃基板等 级和品质。
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， 因此依本发明权利要求所作的等同变化， 仍属本发明所涵盖的 范围。
