  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 visual defect detection has the advantages that cannot be surpassed by manual detection. There are many difficulties in the traditional manual detection
  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.
  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.
  Defect type and location: different surface defect shapes and locations pose a severe challenge to 100% quality control.
  Defects within geometric tolerance: due to the height and depth of some surface defects, defects less than the geometric tolerance cannot be detected.
  The 3D vision defect detection solution can complete the above manual inspection work, and completes the inspection task excellently.
  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.
  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).
  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.
  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.
  3D visual defect detection of automobile brake pads
  On line detection of brake pads, the detection accuracy of Z direction is as high as 1.1 μ M. The maximum and minimum heights are measured and averaged to determine the acceptable surface finish.
  In the application of automobile interior surface detection, 3D vision defect detection intelligent sensor is used to detect the surface of plastic molding products, such as instrument dial, inside of door panel, console and seat.
