For example, in the food industry, a visual inspection sorting device can be used to detect and sort out defective or foreign foods. In the manufacturing industry, it can be used to detect and sort out parts or products with quality problems.

[0003] For example, a fruit and vegetable sorting device based on visual inspection disclosed in the authorization announcement number CN219519616U includes a feed hopper, a sorting controller, a gas nozzle and a flexible conveyor belt. A bracket is welded at the lower end of the feed hopper, a feed pipe is connected to the lower part of the feed hopper, transmission rollers are installed at both ends of the flexible conveyor belt, a controller support frame is welded on the side of the mounting base, and a sorting controller is installed at the upper end of the controller support frame. After adopting the above technical solution, the beneficial effects of the utility model are as follows: due to the setting of the inner diameter of the feed pipe, it is ensured that fruits and vegetables can fall on the surface of the flexible conveyor belt one by one, and at the same time, the gas nozzle is used to screen the identified defective products according to the fruit and vegetable images taken by the camera, with a high degree of automation, reduced manpower expenditure, and cost savings.

[0004] Although the above patent can use a gas nozzle to screen the identified defective products according to the fruit and vegetable images taken by the camera, and the qualified fruits and vegetables selected fall into the qualified product receiving box and are protected by the sponge layer for shock absorption, the next fruit and vegetable that enters will still collide with the previous fruit and vegetable that entered the qualified product receiving box, causing damage to the fruits and vegetables.

[0024] In this embodiment, when the device is used to sort fruits and vegetables, the fruits and vegetables are put into the belt conveyor 1 from the end away from the frame 3, and then the fruits and vegetables are conveyed to the bottom of the visual camera 8 by the belt conveyor 1 and then stopped. At this time, the fruits and vegetables are visually inspected by the visual camera 8, and the height of the visual camera 8 can be adjusted by controlling the lifting platform 7 to rise and fall by the second electric push rod 6, so that fruits and vegetables of different heights can be adapted for inspection.

[0025] like Figure 1 and Figure 3As shown, the sorting mechanism also includes a first electric push rod 11, a push block 12 and a through slot 13. The first electric push rod 11 is fixedly connected to the outside of the left bottom end of the bracket 2. The output shaft of the first electric push rod 11 is fixedly connected to the push block 12. The through slot 13 is penetrated through the right bottom end of the bracket 2. A waste box 14 is provided at the outer bottom end of the belt conveyor 1 near the through slot 13.

[0026] In this embodiment, when the detected fruits and vegetables are unqualified, the first electric push rod 11 is started, and the first electric push rod 11 controls the push block 12 to push forward, so that the fruits and vegetables enter the through groove 13 from the belt conveyor 1, and then fall into the waste box 14 on the other side for centralized collection.

When the detected fruits and vegetables are unqualified, the first electric push rod 11 is started, and the first electric push rod 11 controls the push block 12 to push forward, so that the fruits and vegetables enter the groove 13 from the belt conveyor 1, and then fall into the waste box 14 on the other side for centralized collection. When the fruits and vegetables are detected to be qualified, the belt conveyor 1 is started, and the belt conveyor 1 controls the fruits and vegetables to enter the guide plate 5. The fruits and vegetables slide from the guide plate 5 to the side of the material stripping plate 17 at the top of the roller conveyor 4 and are blocked, and the apple hits the soft pad 18 on the outside of the material stripping plate 17 to avoid damage, and then the motor 16 is started, and the motor 16 controls the material stripping plate 17 to flip 90°. At this time, the first fruit and vegetable is pushed to the other side of the roller conveyor 4, and the second fruit and vegetable will be blocked by the second material stripping plate 17.
