| 摘要:为实现烟用接装纸涂胶厚度的准确检测，搭建了光谱共焦检测系统，实现了接装纸表面胶黏剂厚度和分布均匀性的测量，通过对比扫描电子显微镜形貌分析结果，进一步验证了光谱共焦检测方法的准确性。结果表明，光谱共焦系统能够精准捕捉同一样品涂胶区域胶黏剂厚度的细微差异。不同类型接装纸的胶黏剂厚度有明显不同，所检测的3种类型接装纸表面的胶黏剂厚度范围为8.7~15.1 μm。光谱共焦检测结果的热力图能够直观展示烟用接装纸涂胶区的胶黏剂分布，涂胶区域的厚度变异系数能够有效表征该区域胶黏剂分布的均匀性，从而为评价涂胶质量提供量化依据。 |
| Abstract:To achieve accurate detection of the adhesive thickness of cigarette tipping paper， a spectral confocal detection system had been established. This system enabled the measurement of the thickness and distribution uniformity of adhesives on the surface of the tipping paper. By comparing the results with those obtained from scanning electron microscopy， the accuracy of the spectral confocal detection method had been further verified. The results showed that the spectral confocal system was capable of precisely capturing subtle differences in the thickness of adhesives in the gluing areas of the same sample. The adhesive thickness of different types of tipping paper had obvious difference， with the measured thickness ranging from 8.7 to 15.1 μm across three types of samples. The heatmaps generated from the spectral confocal detection results offered a visual representation of the distribution of adhesives in the gluing areas of cigarette tipping paper. The coefficient of thickness variation in the gluing areas effectively characterized the uniformity of adhesive distribution in that region， providing a quantitative basis for evaluating the gluing quality. |
