The machine vision system converts the captured target into an image signal through an image capture device, transmits it to a dedicated image processing system, obtains the morphological information of the captured target, and converts it into a digital signal based on pixel distribution, brightness, color and other information; the image system performs various operations on these signals to extract the characteristics of the target, such as area, quantity, position, length, and then outputs the results according to the preset tolerance and other conditions, including size, angle, number, qualified or unqualified, existence, etc., to achieve automatic recognition function, and then control the device action according to the judgment result.

[0003] In the process of automatic sorting of steel plates, since some steel plates are attached with a lot of impurities and oil stains, errors in curvature detection will be caused during machine vision recognition, which will reduce the accuracy of sorting. This will result in many steel plates that may meet the requirements being incorrectly screened out, causing great trouble to the work. Therefore, the present application proposes an automatic sorting device based on visual recognition. Utility Model Content

A collecting box 31 is arranged in the slot 30. The collecting box 31 is used to collect steel plates that meet the requirements. The collecting box 31 is connected to the guide channel 29. The steel plates that meet the requirements are transported from one side of the conveyor belt 2 to the guide channel 29 and enter the collecting box 31.

[0033] like Figure 1 and 2 As shown, the sorting device also includes: support columns 3 fixedly mounted on the operating table 1 and located on both sides of the conveyor belt 2, four support columns 3 are symmetrically fixed on both sides of the operating table 1, fixed plates 4 are fixedly mounted on the support columns 3, one fixed plate 4 is fixed on every two support columns 3, and a moving device is arranged on the fixed plate 4;

[0035] Furthermore, the driving motor 9 is started, the threaded rod 6 rotates, and under the guidance of the guide shaft 7, the movable plate 8 can move back and forth on the threaded rod 6.

[0036] like Figure 1-3 As shown, the sorting device also includes a cylinder 5 connected to the moving device, the piston rod of the cylinder 5 is connected to a connecting plate 10, and the connecting plate 10 is driven to descend by the extension of the piston rod of the cylinder 5, and a visual recognition component is provided on the operating table 1;

[0037] Furthermore, the visual recognition component includes a support rod fixedly mounted on the operating table 1, a horizontal plate 22 is connected to the support rod, a visual recognition sensor 23 is fixedly mounted on the bottom of the horizontal plate 22, a lens is arranged below the visual recognition sensor 23, and the visual recognition sensor 23 senses the steel plate passing by by scanning the lens, and the visual recognition sensor 23 is connected to a screening mechanism through a controller;
