In addition, due to the obstruction of the conveyor belt, it is also difficult to perform visual inspection on the bottom of the nut product, making the nut product yield detection not comprehensive enough.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1

[0024] Reference Figure 1-3 , a visual inspection device for nut product yield inspection, comprising a transparent conveyor belt 2 installed on a U-shaped frame 1, a nut double-sided visual inspection mechanism and a nut sorting mechanism;

[0025] In this embodiment, the nut double-sided visual inspection mechanism includes an L-shaped fixed rod 3 fixedly connected to the top outer wall of the U-shaped frame 1, an upper light source 4 and an upper industrial camera 5 fixedly installed on the top lower side wall of the L-shaped fixed rod 3 in sequence, a connecting rod 6 fixedly connected to the front lower inner wall of the U-shaped frame 1, and a lower light source 7 and a lower industrial camera 8 fixedly installed on the top outer wall of the connecting rod 6 in sequence. Through the cooperation of the upper light source 4 and the lower light source 7, a good light field of view can be provided to the upper industrial camera 5 and the lower industrial camera 8;

[0026] In this embodiment, the nut sorting mechanism includes an L-shaped support frame 10 fixedly connected to the top outer wall of the U-shaped frame 1, an electric push rod 11 fixedly installed on the top outer wall of the L-shaped support frame 10, a material blocking plate 12 fixedly connected to the telescopic end of the electric push rod 11, an electric push rod 2 13 fixedly connected to the rear outer wall of the U-shaped frame 1, a push plate 14 fixedly connected to the telescopic end of the electric push rod 2 13, a defective product discharge port 15 fixedly connected to the front outer wall of the U-shaped frame 1, and a good product push port 16 fixedly connected to the outer wall of one side of the U-shaped frame 1;

[0027] Furthermore, an image processing industrial controller 9 is fixedly installed on the front outer wall of the U-shaped frame 1, and the upper industrial camera 5, the lower industrial camera 8, the electric push rod 1 11 and the electric push rod 2 13 are all electrically connected to the image processing industrial controller 9;

[0028] In the specific implementation of this embodiment: first, the upper industrial camera 5 and the lower industrial camera 8 can be used to visually inspect the top and bottom surfaces of the nuts conveyed on the transparent conveyor belt 2, thereby improving the comprehensiveness of the nut product yield inspection;

[0029] Secondly, the upper industrial camera 5 and the lower industrial camera 8 will transmit the nut image information that has undergone visual inspection to the image processing industrial controller 9, which will process and analyze it to facilitate the determination of whether the nut is a good product. When the nut is detected to be a good product, the nut will automatically be rejected from the good product discharge port 16. When the nut is detected to be a defective product, the electric push rod 11 will drive the baffle plate 12 to move downward to block the nut, and then the electric push rod 2 13 will drive the push plate 14 forward to push the blocked nut to the defective product discharge port 15 for discharge. This makes it easy to sort the nuts after the visual inspection is completed, and is beneficial for automatically removing defective nuts.

[0033] Furthermore, the telescopic ends of the two electric push rods 3 20 are respectively fixedly connected to the two connecting rods 19, and the two electric push rods 3 20 are connected to the same control switch through the same wire;

[0034] During the specific implementation of this embodiment: the two limit plates 18 can be used to limit the nut products conveyed on the surface of the transparent conveyor belt 2, which can prevent the nut products from deviating during the conveying process, thereby helping to improve the efficiency of nut product yield detection, and the two limit plates 18 can be controlled to move away from or towards each other through the telescopic effect of the telescopic ends of the two electric push rods 20, so that the limit spacing between the two limit plates 18 can be flexibly adjusted, which can adapt to the use of limit and anti-deviation of nuts of different specifications.
