Description

一种镭射纸的检测方法 技术领域
本发明涉及检测技术领域，更具体地说，涉及一种镭射纸的检测方法。
背景技术
目前，光棒光柱镭射纸经常存在光柱歪斜的现象，这种歪斜会造成转移膜歪斜，进一步造成造纸光柱歪斜，最终导致印刷废品。行业内进行来料检测时主要通过人的眼睛进行观察和计数，这种检测方法的缺陷主要有：（ 1 ）检测精度不高，细微的偏斜很难检测出来；（ 2 ）眼睛识别时容易造成眼睛视力疲劳；（ 3 ）检测效率极低，大批量生产很难做到全面检测；（ 4 ）不能对光柱歪斜程度是否影响产品质量做出直观判断，导致容易误判。
发明内容
本发明要解决的技术问题在于，针对现有技术中镭射纸的检测存在精度不高且检测效率较低的缺陷，提供一种镭射纸的检测方法，能够对镭射纸进行精确高效地检测。
本发明解决其技术问题所采用的技术方案是：一种镭射纸的检测方法，包括以下步骤： S1 ：制作一种菲林，所述菲林包括间隔设置的多个非透光条，相邻所述非透光条之间通过透光条隔开； S2 ：通过光线照射所述菲林，光线通过所述透光条形成入射光线 b1 ，所述入射光线 b1 照射到镭射纸上被反射形成光线 b1´ ； S3 ：光线照射在所述镭射纸的光棒光柱上被反射形成光线 b2´ ；如果所述光线 b1´ 与所述光线 b2´ 相互干扰形成干涉纹，则所述镭射纸上的光棒光柱偏斜；如果所述光线 b1´ 与所述光线 b2´ 未形成干涉纹，则所述镭射纸上的光棒光柱没有偏斜。
本发明镭射纸的检测方法，优选的，所述镭射纸是通过模压将转移膜上的光棒光柱转移到纸上形成。
本发明可达到以下有益效果：该检测方法能够精确且方便地检测光棒光柱是否歪斜，避免造成印刷次品废品；同时能够提高检测效率，适合大批量检测。
附图说明
下面将结合附图及实施例对本发明作进一步说明，附图中：
图 1 是本发明的镭射纸的检测原理示意图；
图 2 是本发明的镭射纸的检测方法的流程示意图。
附图标号说明：

11 、光棒光柱
2 、菲林
21 、非透光条
22 、透光条
具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
如图 2 所示，为本发明提供的一个实施例，一种镭射纸 1 的检测方法，包括以下步骤： S1 ：制作一种菲林 2 ，所述菲林 2 包括间隔设置的多个非透光条 2221 ，相邻所述非透光条 2221 之间通过透光条 22 隔开，此处菲林（ film ）是指印刷制版中的感光底片；参照图 1 所示， S2 ：通过光线照射所述菲林 2 ，光线通过所述透光条 22 形成入射光线 b1 ，所述入射光线 b1 照射到镭射纸 1 上被反射形成光线 b1´ ； S3 ：光线照射在所述镭射纸 1 的光棒光柱 11 上被反射形成光线 b2´ ；如果所述光线 b1´ 与所述光线 b2´ 相互干扰形成干涉纹，则所述镭射纸 1 上的光棒光柱 11 偏斜；如果所述光线 b1´ 与所述光线 b2´ 未形成干涉纹，则所述镭射纸 1 上的光棒光柱 11 没有偏斜。
在上述技术方案的基础上，进一步的，镭射纸 1 是通过模压将转移膜上的光棒光柱 11 转移到纸上形成。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，这些均属于本发明的保护之内。
