3d视觉缺陷检测系统能够精确地完成表面检测

浏览量
  3d视觉缺陷检测在汽车制造业的重要性不容小觑,在汽车制造的每一个环节都必须要保证产品外面及表面的完整与美观度。3d视觉缺陷检测系统能够准确的完成表面检测的过程,保证产品的合格率。
  The importance of 3D visual defect detection in the automobile manufacturing industry can not be underestimated. In every link of automobile manufacturing, it is necessary to ensure the integrity and beauty of the product exterior and surface. 3D vision defect detection system can accurately complete the process of surface detection and ensure the qualified rate of products.
  3d视觉缺陷检测有着人工检测无法超越的优势,传统的人工在检测环节存在很多困难,常见的有:
  3D visual defect detection has the advantages that cannot be surpassed by manual detection. There are many difficulties in the traditional manual detection
  人工检测的局限性:CMM能实现精确地进行表面检测,但对于高速在线过程而言,它不仅速度太慢,而且成本高昂。
  Limitations of manual inspection: CMM can realize accurate surface inspection, but for high-speed online process, it is not only too slow, but also expensive.
  材料表面变化:不同行业的材料表面属性存在着显著的差异——从低对比度的黑色橡胶表面、到诸如玻璃或塑料之类的高反射性或透明材料。
  Material surface changes: there are significant differences in material surface properties across industries - from low contrast black rubber surfaces to highly reflective or transparent materials such as glass or plastic.
  缺陷类型和位置:表面缺陷形状及位置不同,对于100%的质量控制提出了一项严峻的挑战。
  Defect type and location: different surface defect shapes and locations pose a severe challenge to 100% quality control.
  几何公差范围内的缺陷:由于一些表面缺陷的高度和深度,检测不到小于几何公差的缺陷。
  Defects within geometric tolerance: due to the height and depth of some surface defects, defects less than the geometric tolerance cannot be detected.
  3d视觉缺陷检测解决方案能够完成以上人工无法完成的检测工作,并且出色的完成检测任务。
  The 3D vision defect detection solution can complete the above manual inspection work, and completes the inspection task excellently.
  自动化非接触检测:非接触式3D智能传感器对表面材料没有损伤,能产生高精确和高度可重复的测量数据,并且能与在线生产速度相匹配。
  Automatic non-contact detection: the non-contact 3D intelligent sensor has no damage to the surface material, can produce high-precision and highly repeatable measurement data, and can match the online production speed.
  处理多种类型的表面材料:3D智能传感器提供多种曝光方法和数据处理算法,用于处理反光表面(如小型电子零件)和低对比度的表面(如轮胎面和侧壁)。
  Processing multiple types of surface materials: 3D smart sensors provide a variety of exposure methods and data processing algorithms for processing reflective surfaces (such as small electronic parts) and low contrast surfaces (such as tire tread and sidewall).
  缺陷识别与分析:3D智能传感器内置锚定和零件匹配功能,以确保在传送带上传送的每个零件的相同位置都被检测到,而不管零件位置如何变化。
  Defect identification and analysis: 3D intelligent sensor has built-in anchoring and part matching functions to ensure that the same position of each part transported on the conveyor belt is detected, regardless of how the part position changes.
  亚微米级的高分辨表面特征检测:为了实现更高的检测精度,使用计量级3D技术(例如结构光扫描检测)进行精度达亚微米级的表面分析。
  Sub micron level high resolution surface feature detection: in order to achieve higher detection accuracy, metrological level 3D technology (such as structured light scanning detection) is used for surface analysis with sub micron accuracy.
