通过与Keyence（泰国）的合作实现！为了降低成本而进行的外观检查自动化/YN2-TECH × KEYENCE

中村亮太

总经理

你好。我是YN2-TECH的中村。
对于致力于新产品制造的客户，本公司以全方位支持的业态，提出开发相关工具的销售和 DPE （Digital Production Engineering）的方案。并且，致力于使用3D数据和使用数字技术的生产技术开发和自动化。

此次，我想和FA（工厂自动化）的龙头企业“keyence”的住先生，以在泰国的《为了降低成本而进行的外观检查自动化》为主题进行对话。

开发影像检测仪
和keyence的住先生的相遇

中村：YN2-TECH 和 keyence 合作的关键是接受客户咨询的图像检查装置的开发。这难度非常大，而且是短期开发的案件。

住：因为是第一次的案件，所以担心是否真的能解决。

中村：在生产线中如何进行使用图像的分析是一项挑战。
即使用相机拍照，怎么进行分析呢？　分析部分的开发非常难。

住：使用 keyence 的图像处理算法进行实际测试时，在一定程度上确信分析部分的课题也能解决。

外观检查装置由“绘画”决定

中村：keyence 的技术水平非常优秀。
我想请教一下外观检查技术中的重点。

住：由绘画决定使用图像处理的外观检查是否成功。
keyence 正在关注如何制作出软件方面容易处理的画。

通过外观检查的“量化”降低成本

中村：请告诉我此次的主题，即关于通过外观检查的自动化来降低成本。

住：成本削减效果最大的是“目视检查的置换”。
将人海战术的大部分检查自动化，交给照相机。于是，需要5人的工作可以一个人完成，有很多类似的事例。

中村：住先生的提案给我留下印象的关键词是“外观检查的量化”这个词。
通过人进行的外观检查，即使有作为检查基准的样品，如果白天的班次和晚上的班次检查员不同，也会出现差异。搞不好因心情的不同也会产生差异。在这种情况下，我认为“可以定量化”是重要的关键词。

住：本来外观检查中OK和NG的分界线就非常模糊。
如果是图像处理，可以设定一定的数字，超过该数字后设定为NG，低于该数字则设定为OK。因为是机械地用数字判断，所以基本上不会发生漏掉的情况。

外观检查自动化提高的可靠性和未来的订单预计

中村：深入探讨自动化降低成本的问题。我想也有人工费以外的削减效果，您觉得如何？

住：让顾客高兴的例子是，一旦推出NG产品，回收费用就是巨额开支。以千万铢为单位会损失金钱。通过自动化，可以将NG产品造成的损失风险最小化。

中村：如果考虑到索赔品回收的地点不仅是泰国，费用的金额有可能是无法想象的金额。
对泰国等东南亚客户来说，外观检测装置可能成为稳定企业利润的设备。也就是说，“不仅是减少检查人员，而且是产生长期收益的设备”。

住：除了降低风险效果之外，引入后还会提高用户的信任度，有利于增加日后的订单。

中村：在因新冠肺炎疫情的影响市场逐渐缩小的情况下，在保护自身的同时，进行外观检查，现在才是需要引进的吧。
