Display Panel Surface Micro-Defect AOI Machine
A two-cabinet AOI machine for surface micro-defects on display panels, with a 2D inspection station and a 3D inspection station, each on its own XY linear-motor marble platform. Panels are loaded manually, the panel ID is read and the panel goes through USC cleaning; the 2D station inspects for scratches, dimples and chipping, a transfer robot moves the panel to the 3D station for dimple and dent depth inspection, and the panel is unloaded with an OK/NG result. Model changeover covers 7～17.3 inch panels.

- Algorithm
- CV algorithm + AI deep learning
See it in action
Silent clips from our 3D machine animations. While a clip is playing, you can pause it from the corner button.
3D animation Transfer: the robot lifts the panel off the 2D station and sets it down on the stage of the 3D station.
Highlights
2D + 3D inspection in one machine: a 2D station for scratches, dimples and chipping, and a 3D station for dimple and dent depth
Each station runs on its own XY linear-motor marble platform; XY repeat positioning accuracy ±2um
Detects scratch, dimple and chipping defects with length/width ≥10um
3D station scans the panel with a laser line and inspects defect depth ≥1um
CV algorithm + AI deep learning
Defect mapping: defect positions are plotted on a map of the panel
Panel ID reading and USC cleaning before inspection
Model changeover for 7～17.3 inch panels
Down-flow air inside the enclosure
Overkill rate <5%, escape rate <0.05%
Typical application
Surface micro-defect inspection of display panels
