[0062] The Y-axis translation drive cylinder drives the first carrier to the exit state, and the product of the upstream process is placed on the first carrier through the manipulator. Then the Y-axis translation drive cylinder drives the first carrier to reach the bottom of the picking head of the first picking mechanism, and then the material lifting mechanism drives the material handling frame to descend. After that, the picking head of the first picking mechanism picks up the product on the first carrier and drives it to rotate 90° through the rotating cylinder (since the product obtained in the upstream process is not in the state required for visual inspection, it needs to be rotated). At the same time, other picking heads also pick up the products on the corresponding carriers. Then the material translation drive mechanism drives the material handling frame to move step by step along the X direction, and the first picking mechanism moves to the second carrier. The product is placed directly above the tool, then lowered into position to place the product on the second carrier, and then the Y-axis detection translation drive mechanism 62 drives the first camera 61 to translate along the Y-axis to detect the bottom surface of the product; then the product is moved to the third carrier in the same moving process as above, and the second visual inspection mechanism 7 detects the side of the product, and then the product on the third carrier is moved to the fourth carrier, and then the Z-axis detection translation drive mechanism 82 drives the third camera 81 to detect the upper surface of the product, and finally the product is moved to the turntable, and the turntable 51 is driven to rotate by the rotation drive mechanism 54, and according to the detection data recorded in the control system, the product is blown into the corresponding discharge box through the blowing nozzle to distinguish the discharge.
