AI Technical Summary
In the existing technology, the abnormal area of the thermoformed door ring lacks precise positioning in the three-dimensional structure, which easily leads to deviation between the marking position and the abnormal area. In addition, the existing marking method may cover the surface morphology of the abnormal area, affecting the accuracy of subsequent rework positioning and quality traceability.
An automatic marking system for defects in thermoformed door rings is adopted, including data acquisition, coordinate mapping, surface detection and shape detection modules. A three-dimensional structural map is constructed through 3D data, and combined with image analysis, the surface and shape anomalies are accurately located and distinguished. The automatic marking module is used to mark the defects precisely.
It enables comprehensive and precise inspection of thermoformed door rings, ensuring accurate dot placement, avoiding surface morphology obstruction, and improving the accuracy of rework positioning and quality traceability.
