Abstract
本申请公开了一种丁腈手套生产缺陷在线识别方法及系统，涉及橡胶手套制造及缺陷检测技术领域。该识别方法包括：在丁腈胶乳配制阶段加入荧光示踪剂；将手模浸入混合胶乳形成湿膜状态的丁腈手套初品；在进入烘干硫化工序前，通过紫外光源对移动中的手套初品进行激发照射；采用图像采集装置获取荧光图像；对荧光图像进行处理，提取荧光特征并基于此识别凝胶和 / 或气泡缺陷。本申请利用凝胶区域对示踪剂的富集作用形成高亮实心特征，以及气泡气液界面的折射散射作用形成暗心亮环特征，将湿膜状态下低对比度的缺陷转化为高对比度的荧光信号，实现了非接触式早期在线识别，并结合缺陷分类与工艺闭环调整，显著提升了缺陷检出率与生产良率。
