Further, referring to fig. 1, the front side detecting unit 21 and the back side detecting unit 22 each include a camera and a light source. In particular, the camera is an area-array camera. Thus, when the conveying line 10 conveys the product 90 to be detected through the front detection mechanism 21 and the back detection mechanism 22, the cameras of the front detection mechanism 21 and the back detection mechanism 22 respectively shoot the top and the bottom of the product 90 to be detected, so that the shooting detection is realized. Moreover, by arranging the light source, the light source can provide light rays for covering the product to be detected 90, the camera can be ensured to clearly and completely shoot the image of the product to be detected 90, and the detection precision is improved.
Further, the visual inspection device 20 further includes a fourth elevating mechanism, and the front surface inspection mechanism 21 is mounted on the fourth elevating mechanism. Thus, when the front detection mechanism 21 needs to detect the appearance defect at the top of the product to be detected, the fourth lifting mechanism drives the front detection mechanism 21 to move along the direction close to the product to be detected so as to detect the appearance defect at the top of the product to be detected; after the detection is finished, the fourth lifting mechanism drives the front detection mechanism 21 to move in the direction away from the product to be detected, so that the movement interference is avoided.
Specifically, in this embodiment, the reverse side detection mechanism 22 and the front side detection mechanism 21 are respectively disposed at intervals along the conveying direction of the conveying line 10, that is, the bottom defect of the product 90 to be detected is detected by the reverse side detection mechanism 22, and then the top defect of the product 90 to be detected is detected by the front side detection mechanism 21.
