An environmental paper defect visual detection device
By designing an environmentally friendly visual inspection device for paper defects, a curved rod is used to push the paper material to arch up, which, combined with the movement of the visual inspection instrument, solves the problem that planar inspection technology cannot identify curved surface defects. This achieves efficient and accurate defect detection, meeting the needs of industrial production.

Abstract
本发明公开了一种环保纸张缺陷视觉检测装置，涉及新材料检测技术领域，包括门架，门架上设置有输送装置，输送装置包括支撑板，支撑板上设置有与传送机床相配合的输送带组件，支撑板上还开设有四个路径槽，本发明可通过曲杆的相对位移将待检测纸张拱起，模拟其实际应用中的曲面拉伸状态，让平展状态下难以识别的微小缺陷充分显现，显著提升漏印、纸张破损等隐性缺陷的检出率，同时曲杆移动前期可自动修正纸张偏移，配合曲块的偏转，保障检测过程不损坏纸张本身，而视觉检测仪的工作过程可视为始终保持与拱起纸张的法线对齐状态，配合可按需进行多次检测的功能，避免了单次采样带来的误差，大幅提升图像采集与缺陷判定的准确性。
