APPEARANCE DETECTION DEVICE AND APPEARANCE DETECTION METHOD FOR PRODUCT TO BE DETECTED

Disclosed are an appearance detection device and an appearance detection method for a product to be detected (1'). The appearance detection device includes a conveying system (600), and the conveying system (600) comprises a conveying track (640) as well as feeding and blanking clamps (610, 620) and a transfer device (630) located on the conveying track (640). A main surface detection system (100), a middle frame detection system (200), a concave detection system (300) and a convex detection system (400) are arranged along the conveying track (640). The main surface detection system (100) is configured to detect the main surfaces (11', 12') of the product to be detected (1'); the middle frame detection system (200) is configured to detect a middle frame portion (13') of the product to be detected (1'); the concave detection system (300) is configured to detect grooves disposed in the main surfaces (11', 12'); and the convex detection system (400) is configured to detect planes protruded on the main surfaces (
