Description

具有太阳能电池组的发光元件检测机台及其检测方法 【技术领域】
本发明是关于一种发光元件检测机台及其检测方法，特别是具有太阳能 电池组的发光元件检测机台及其检测方法。 【背景技术】
为获取发光元件的全光通量， 业界常以积分球撷取发光元件受致能后发 出的光能， 进而分析求取发光元件的全光通量值。 量测环境如图 1所示， 积 分球 11通过光纤连结光谱能量分析仪， 积分球 11内部更包括一遮板 13， 待 测 LED是定位于积分球 11的下方输入部处，而输入部的大小为输入部截面 积；积分球 11相对于输入部的另一端具有一位于其上方处的输出部，而输出 部的大小为输出部截面积。
当待测 LED受致能点亮， 光能由输入部进入积分球 11 , 再透过积分球 11的内部折射， 将光能由输出部收取并输出， 即由光纤传递至光谱能量分析 仪， 经标准光源于相同环境量测比对后可得待测 LED 的全光通量， 此检测 模式较适用于具有指向性的光源。 而积分球 11 的大小造成需设置时有所限 制， 通常仅见规划于实验室中， 且不断置入 /取出待测光源， 进行不同待测 LED的量测也相当耗费时间， 积分球 11的造价也不低。
因此，如图 2所示的全光通量检测系统，光接收装置 20的内侧六面设置 有六片太阳能电池，输出部为光接收装置 20的输出点，受测的待测光棒载放 于移动装置上的置放座， 通过空缺区 28循序进入光接收装置 20中， 当受测 待测光棒受置放座致能而点亮， 待测光棒的光能即透过太阳能电池接收。
随后于光接收装置 20中，待测光棒的光能经两个路径传送，一路径为经 传输装置传输至处理器； 另一路径为通过光纤传送至光谱能量分析仪， 再由 光谱能量分析仪经传送装置至处理器； 结合两路径数据由处理器进行分析， 可获得待测光棒的全光通量值。
与图 1中的积分球系统相比， 图 2结构不仅太阳能电池取得容易、 价格 低廉、 易于维修保养， 将待测光棒循序经移动装置的置放座送进光接收装置 20中的动作， 更大幅节省检测时间， 结合光谱能量分析仪与处理器， 可获得 待测光棒更精确的全光通量值。
然而， 该公知技术仅论及其全光通量， 而本发明不仅可以太阳能电池对 待测光源就感测定位后静态感测整个待测光源是否为良品， 更能通过动态亮 度感测， 细部论究整个待测光源内拥有众多发光元件时， 众多发光元件中何 者有误； 亦即， 一旦发现某发光组件出现问题， 无须额外经由一个步骤确认 发光有误的元件何在， 即可正确分辨待测发光组件的所有发光元件是否均为 符合检测标准的良品， 迅速确认出非良品的受测元件， 将可加速后续修正处 理速度，就此提升产出良率；尤其当此种分辨是经由相同的自动化作业流程， 更能迅速在检测过程中， 大量检验待测发光组件而具备实用价值， 解决生产 发光组件与检测发光组件厂商的困境， 实为最佳的解决方案。 【发明内容】

利用上述机台的检测方法即为一种具有多个发光元件的发光组件检测方 法， 其中发光组件中的发光元件是沿着一个长度方向配置， 并由一具检测机 台检测发光组件中发光元件发光状态， 其中检测机台包括一个基座； 一组设 于基座、 具有一个可涵盖多个发光元件的感测范围、 用以感测发光元件发光 并转换为感测讯号输出的太阳能电池组； 及一组将发光组件与太阳能电池组 沿一个预定移动方向相对移动的移动装置， 该方法包括下列步骤： a)将发光 组件之一以长度方向吻合于预定移动方向方式置放， 并以基座致能待测发光 组件的发光元件发光； b)以移动装置将发光组件与太阳能电池组沿预定移动 方向移动，使得待测发光组件的发光元件循序进入及 /或脱离太阳能电池组的 感测范围；及 c)由太阳能电池组感测依照发光元件进入及 /或脱离感测范围状 态， 输出所感测发光量随感测范围内发光元件状态及时间变化的感测讯号。
承上所述， 本发明提出一种具有太阳能电池组的发光元件检测机台及其 检测方法，藉由让发光组件中的多个发光元件循序进 Λ/脱离感测范围，使感 测所得的发光亮度， 循序简单递增或递减， 一旦增减状态与预期不符， 则依 照进入 /脱离的速度， 立即推算得知发生问题的发光元件在发光组件中位置， 进一步达成在自动化检测作业中， 立即分辨错误的单一元件， 加速后续修补 或处理流程， 提升产出速率； 尤其不受待测发光组件的长度限制， 更能切合 需求

【具体实施方式】
有关本发明的技术内容、 特点与功效， 在以下配合说明书附图的较佳实 施例的详细说明中，将可清楚地呈现； 且为方便说明，文内所提的发光组件, 其所具有的多个发光元件沿一个长度方向配置， 并省略必备于机台基座的支 架线路， 以免图面紊乱。
敬请参考图 3， 所示内容为本发明第一实施例的方块图， 检测机台的架 构包括检测时致能与承载用的基座 30， 移动装置 32则供批次输入与输出待 测物， 太阳能电池组 33包括至少一片太阳能电池 331， 经太阳能电池组 33 接收的检测讯号则传送至处理装置 35进一步处理与分析。 本案第一实施例的实际结构如图 4及图 5所示， 其中待测发光元件 70 是以发光二极管晶粒为例， 发光元件 70是由晶圆 (WAFER)阶段分割， 并被 分离置放于基座 30上,移动装置 32在本例中则是负责移动基座 30的二维移 动载台， 可将整片晶圆所切割出的数千至数万颗发光元件 70批次移动。
本例中的太阳能电池组 33是以单一片太阳能电池 331为例，并为说明起 见翻转 180°绘示，太阳能电池 331以其作用面 622面向受测发光元件 70，且 在作用面 622朝向发光元件 70侧更配置例释为一片滤色片 624的滤色片组， 在此，选择滤色片组的透射函数系与太阳能电池 331的波长响应函数相乘后， 对应于标准视效函数， 藉以求得与视觉效果相对应的发光亮度； 为使量测误 差缩小， 太阳能电池 331将接近受测发光元件 70， 使得发光元件 70所发光 量主要照射于太阳能电池 331的作用面 622，且远大于逸散至太阳能电池 331 以外的发光量。
如图 6及图 7所示， 此为本发明第二实施例， 发光组件检测机台 3'系供 量测具有多个发光元件 70的发光组件 7的发光状态，并包括:一个用以承载、 致能发光组件 7的基座 30'、 一组可同时感测多个发光元件 70的感测装置及 一组移动装置 32'。
承上所示， 以太阳能电池组 33'为感测装置， 及以具有多个发光二极管 的光棒作为具有多个发光元件 70的例证。 当检测机台 3'开始进行检测时， 先将待测发光组件 7置放于移动装置 32'， 使待测发光组件 7发光面朝上， 并坐落于远离太阳能电池组 33'感测范围的预备位置 0; 续由基座 30'致能待 测发光组件 7， 使多个发光元件 70发光。
在此需强调， 若以一条光棒上具有 60颗 LED晶粒， 并被区分为彼此间 隔交错的六组，则所谓致能多个发光元件发光，并非限制所有 LED晶粒都必 须同时发光， 亦可选择例如一组十颗晶粒同时被致能发光， 其余五组则暂时 不点亮， 其依照时序循序检测， 并无不可。
为便于说明起见， 定义下文步骤中， 移动装置 32'如图 8所示驱动发光 组件 7移动的方向， 称为预定移动方向， 此预定移动方向必然对应于上述发 光组件 7的长度方向， 使得本例的待测发光组件 7中， 被点亮的第一个发光 元件 70由上述预备位置进入太阳能电池组 33'的感测范围。 且被点亮的发光 元件 70是以例如一恒定速度依序加入感测范围中。直到如图 9所示，所有受 测发光元件 70完全进入太阳能电池组 33'感测范围， 并称此位置为完全感测 位置 81。 假设所有被量测的发光元件亮度均正常， 彼此发光亮度差异甚低， 则量得的亮度将如图 12所示，由预备位置 0的全无亮度，递增至标示为对应 完全感测位置 81的极大值。
当然， 如熟悉本技术领域者所能轻易理解， 上述量测发光递增的程序， 亦可被反向操作为递减量测程序。为便于说明，将图 10所示被点亮的各发光 元件中的第一颗即将脱离太阳能电池组 33'的感测范围时， 称为预备脱离位 置 82; 并逐步量测直到如图 11所示， 受测发光元件 70到达全数脱离太阳能 电池组 33'感测范围的完测位置 E; 从而取得如图 12后半程所示， 量得亮度 由对应预备脱离位置 82的极大值， 逐步递减至对应完测位置 E的原始基准 亮度。
如图 11所示，随后将前述两种度量感测过程中任选一者 (或两者皆处理)， 由处理装置 35'依照彼此对应的感测讯号与时间顺序， 于后， 由感测讯号推 算太阳能电池组 33' (太阳能电池)对应受测物发光状态反应的电性状态变化， 检知发光组件是否为良品。 一旦有任何发光元件 70未达预定标准， 则如图 13所示，原先的递增上升趋势 (或递减的下降曲线)将产生一处非理想的折曲， 即可依时间顺序 (t)计算出此未达良品标准的发光元件位置在何处。
由于例如光棒的长度有日渐增长的趋势， 故如本发明第三实施例图 14 所示， 当检测机台 3"受到空间限制， 太阳能电池组 33"的感测范围无法同时 涵盖发光组件 7"内所有发光元件； 则感测结果将如图 15或图 16所示，仍可 由上述预备位置 0至所有被点亮发光元件中的最末一位进入感测位置的完全 感测位置， 或由预备脱离位置至完测位置 E的状态， 清楚分析出不合格发光 元件位置。
尤其，由于机械移动的速度远逊于电讯号切换速度，故当图 14所示左右 两侧的发光元件分别属于不同发光组别， 或者是将例如两条 (甚至更多条)光 棒如图 14的左右排列接受检测，亦可轮流点亮左右两排的晶粒、或轮流点亮 两 (或更多)条光棒， 藉以进一步加速感测的产出效率。
由此可见， 本发明可在各款式发光组件检测中， 循元件顺序所反应的发 光状态， 迅速检测其所具未符合标准的发光元件发光状态， 并保持检测机台 检验结果的正确性， 且无须付出过多的成本， 能立即分辨出不良品元件。
惟以上所述者， 仅为本发明的较佳实施例而已， 当不能以此限定本发明 实施和保护的范围， 即凡依本发明申请专利范围及发明说明内容所作简单的 等效变化与修饰， 皆仍属本发明专利涵盖的范围内。
