When the turntable 2 rotates 30 degrees, the transparent carrier plate 6 Rotate 40 degrees. When there are nine detection stations 12 on the side wall, when the turntable 2 rotates by 30 degrees, that is, 1/12 of a circle, each transparent transparent carrier plate 6 is rotated by 40 degrees, or 1/12 of a circle, so that the product can be detected by shooting from 9 angles. Exterior.

As shown in FIG. 1 , a safety gate 101 and a protective grating 102 are set on the rack 1 , the images captured by the first detection camera 71 and the second detection camera 81 will be sent to the background for image analysis, and a display 103 is installed on the table top of the rack 1 To facilitate observation and detection, the front end of the rack 1 has an operating table 104, the operating table 104 is provided with a keyboard drawer 105, and a tri-color light 106 is installed on the top of the rack 1 to remind the operation of the equipment.

Use a fully automatic appearance inspection machine with five side wall inspection stations 12, one end face inspection station 13, one feeding station 11 and one unloading station 14 to describe the working process. The structure of the feeding manipulator 43 of the feeding mechanism 4 grabs the product to be tested from the product placement slot 4621 to the positioning fixture 62 of the transparent carrier plate 6 , the turntable power device 3 drives the main gear 31 to rotate, and the turntable 2 rotates with the main gear 31 , at the same time, the main gear 31 meshes with the transition gear 33 and the transition gear 33 meshes with the large gear 32, the transparent carrier plate 6 rotates with the large gear 32; the product to be tested moves counterclockwise with the turntable 2 from the feeding station 11 to the first A side wall detection station 12, at this time, the turntable 2 rotates 45 degrees, and at the same time, each transparent carrier plate 6 rotates clockwise, and the rotation angle of the transparent carrier plate 6 is 72 degrees; The first detection camera 71 of the side wall detection station 12 takes a picture of the side wall of the product to be tested and collects images. At this time, the feeding mechanism 4 continues to grab the product to be tested to the positioning of the transparent carrier 6 on the feeding station 11 Then the product to be tested moves counterclockwise from the first side wall detection station 12 to the second side wall detection station 12 with the turntable 2. At this time, the turntable 2 rotates 45 degrees, and at the same time, Each transparent carrier plate 6 rotates 72 degrees in the clockwise direction. After the rotation is in place, the first detection camera 71 of the second side wall detection station 12 takes pictures and collects images of the side wall of the product to be tested, and the feeding mechanism 4 is still transparent. The carrier plate 6 is loaded; and so on, when the product to be tested moves with the turntable 2 in the counterclockwise direction to the last side wall detection station 12, each transparent carrier plate 6 completes a circle, that is, rotates 30 degrees, and one circle of the side wall of the product All were photographed and collected by the first detection camera 71; the product to be tested moved with the turntable 2 counterclockwise from the last sidewall detection station 12 to the end face detection station 13, at this time, the turntable 2 rotated 45 degrees, At the same time, each transparent carrier plate 6 rotates 72 degrees in the clockwise direction. After the rotation is in place, the second detection camera 81 takes pictures of the end surface of the product, that is, the bottom surface to collect images; the detected product rotates 45 degrees counterclockwise with the turntable 2 The end face detection station 13 moves to the unloading station 14. At the same time, each transparent carrier plate 6 rotates 72 degrees in the clockwise direction. Go, the good product will be put into the good product box 51, and the bad product will be put into the bad product sum. The fully automatic appearance inspection machine can comprehensively inspect the appearance of the product from different angles, accurately determine whether the appearance of the product meets the standard, and ensure high-quality inspection. Once the equipment is turned on, all stations run simultaneously, which greatly improves work efficiency.
