Description

一种批量钻石快速筛查方法 技术领域
本发明涉及检测设备领域，具体涉及一种批量钻石快速筛查方法。
背景技术
钻石在紫外光的激发下会发出荧光。形有一部分钻石会发荧光，一般是蓝白色的荧光，也有少部分的钻石发黄色的荧光。
钻石具有荧光，部分还可能具有磷光。钻石在受到紫外光照射时，能发出强度不同的蓝色可见光，这就是荧光，如果撤去紫外光源，钻石仍能发出可见光，这就是磷光。
不同钻石的荧光在颜色、强弱上都有较明显的差别，所以成包的钻石在初步鉴定时，最简单的一种方法，就是把钻石在紫外灯的照射下，如果荧光强弱、颜色各不相同，那么就是真钻石，如果颜色强弱均一，则极有可能是钻石的仿制品。
现在经常有不法商贩将人造钻石混杂在天然钻石中，传统的检测手段检测速度慢，非常不利于快速将人造钻石从天然钻石中筛选出来，同时现有的设备和检测方法通常是针对大颗粒的钻石进行检测，而缺少针对碎钻的快速检测手段。通常采购商采购的碎钻数量多，采用传统手段检测任务重，同时对碎钻检测成本高，检测效率低，非常不利于降低采购到假钻石的风险。
发明内容
针对上述问题，本发明旨在提供一种低成本高效的批量钻石快速 筛查方法。

具体实施方式
下面结合附图和具体实施例对本发明做进一步详细说明。
如图1所示，本发明所述的具体实施例为一种批量钻石快速筛查 方法，包括光源1、成像装置2、工作台4、密室3，所述光源1、成像装置2和工作台4均设置在密室3内，具体步骤如下：
第一步，将待检钻石6放置在工作台4上，启动工作台4一侧设置的光源1，通过光源1对待检钻石进行照射，此时照射光为含可见光的光，并通过成像装置2进行拍摄记录钻石分布位置，获得基础成像图；为了获得最佳的效果，此时的照射光
第二步，切换光源1，将照射光切换为含有波长180-250nm的短波紫外线，保持光源照射一段时间后关闭，通过成像装置2进行拍摄记录发出磷光的钻石分布位置，获得磷光分布成像图。钻石的磷光是指钻石在离开紫外线光源的情况下，仍能发出可见光的现象。关闭光源后，通过成像装置能够很便捷的记录钻石在离开紫外光线下的发光现象。同时成像装置还可以记录发光时间和发光强度，通过发光时间和发光强度可提高鉴别的精度。所述短波紫外线功率为25w左右，照射时间约1s，由于磷光的发光时间在1-60s，需要在发光时间内对其拍摄记录。
第三步，将基础成像图、磷光分布成像图进行对照，获得磷光对照图，通过图像识别技术在磷光对照图上标记出发出磷光的钻石，随后通过人工或者设备将发出磷光的异常钻石筛选出来。通常发出蓝绿色磷光的为高温高压合成钻石；只要有蓝绿色磷光则一定认为是合成钻石。
为了获得荧光分布成像图，所述第二步的光源含有波长180-250nm的短波紫外线，将光源开启持续照射，通过成像装置进行 拍摄记录发出荧光的钻石分布位置，获得荧光分布成像图；
将基础成像图、荧光分布成像图进行对照，获得对照图，通过对照图标记出发出荧光的钻石。在可见光线下，具有很强荧光等级的钻石，可以感觉出来，轻微荧光等级同样也很难觉察出来，短波紫外线通过荧光可以作为评估钻石品质和真伪的辅助性指标。
为了方便识别异常钻石的位置，所述工作台上设置有工作格5，所述工作格5设置有标注和编号，所述第三步中对照图上显示有工作格和标注。通过计算机分析计算将蓝绿色磷光所在格子的编号和钻石分布的相对位置，快速标记找出有合成钻石。
为了方便进行人工筛选，避免误操作，所述工作台4上还设置有辅助定位装置7，所述辅助定位装置可以通过可见光线标记异常钻石，通过人工筛选出异常钻石。通过辅助定位装置，通过可见光线照射至标记异常钻石处，方便工作人员识别并筛选出异常钻石。
为了方便进行自动化筛选，所述工作台4上还设置有机械手8，所述机械手通过磷光对照图，将异常钻石筛选出来。通过机械手可以自动运行至标记的异常钻石上方，将异常钻石抓取出来。
一种批量钻石快速筛查设备，包括光源1、成像装置2、工作台4、密室3，所述光源4、成像装置2和工作台4均设置在密室3内，所述工作台4上方一侧设置有光源1，所述工作台4上方还设置有成像装置2，所述光源1包括短波紫外线模块和可见光模块。
为了提供稳定的短波紫外线，，所述光源为氙灯或者氘灯，或者波长为180-250nm的LED光源或者激光光源。如果选择氙灯或者氘 灯，由于氙灯或者氘灯可以发出可见光和紫外光，可在氙灯或者氘灯前设置滤光片即可获得短波紫外线。
为了进行良好的成像，所述成像装置为数码相机或者胶片相机或者摄像机。
为了方便钻石均匀划分分布，所述工作台4上设置有工作格5。
为了方便进行钻石的筛选，所述工作台4上还设置有辅助定位装置7或者机械手8。通过辅助定位装置，通过可见光线照射至标记异常钻石处，方便工作人员识别并筛选出异常钻石。通过机械手可以自动运行至标记的异常钻石上方，将异常钻石抓取出来。
本筛查方法，通过收集钻石的磷光对照图，检测速度快，而且能同时对多颗钻石同时进行筛查，能够大幅提高检查效率，降低筛查成本；而且本筛查方法适合各种状态的钻石的快速检测，能批量未镶嵌的钻石，也可以是镶嵌好的钻石，最小可以测量到0.001ct的钻石，任意形状的钻石均可以，适用范围广；与此同时，采用荧光成像图对照，可以提高筛查的准确率，降低误判概率。
以上所述，仅为本发明的较佳实施例，并不用以限制本发明，凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同替换和改进，均应包含在本发明技术方案的保护范围之内。
