Zusammenfassung: | To achieve efficient and highly accurate all-around inspection for a workpiece.SOLUTION: An inspection device 1 according to an embodiment includes a horizontal rotary conveyor 130, a buffer conveyor 110, an injection conveyor 120, a plurality of cameras 220, an AI inference device 30, and a control device 10. The horizontal rotary conveyor includes a low-speed conveyor 131 and a high-speed conveyor 132, which are provided so that their conveying surfaces are adjacent to each other on the same horizontal plane, and the workpiece W is transported while horizontally rotating on a boundary of the transport surface due to a speed difference between the low-speed conveyor and the high-speed conveyor. The buffer conveyor is provided upstream of the horizontal rotary conveyor. The plurality of cameras are provided at intervals along a conveyance direction so that images of an entire circumference of the workpiece on the horizontal rotary conveyor can be captured. The AI inference device performs AI inference on the captured image using a learning model learned from the image of the workpiece. The control device determines whether the workpiece is good or bad based on an inference result of the AI inference device.SELECTED DRAWING: Figure 5
【課題】効率的かつ高精度なワークの全周検査を実現すること。【解決手段】実施形態に係る検査装置1は、水平回転コンベア130と、バッファコンベア110と、射出コンベア120と、複数のカメラ220と、AI推論装置30と、制御装置10とを備える。水平回転コンベアは、それぞれの搬送面が同一水平面上で隣接するように設けられる低速コンベア131および高速コンベア132を有し、低速コンベアおよび高速コンベアの速度差によってワークWを搬送面の境界上において水平回転させつつ搬送する。バッファコンベアは、水平回転コンベアの上流に設けられる。複数のカメラは、水平回転コンベア上のワークの全周が撮像可能となるように搬送向きに沿って間隔を空けて設けられる。AI推論装置は、ワークの画像から学習された学習モデルを用いて撮像画像に対するAI推論を行う。制御装置は、AI推論装置の推論結果に基づいてワークの良否判定を行う。【選択図】図5 |
