[0023] In the specific implementation process, it is particularly worth noting that through the cooperation between the base 1, the first vision recognition camera 4, the fixing base 12, the vertical frame 13, the limiting groove 14, the connecting seat 15, and the fixing knob 16, through the limiting connection of the connecting seat 15 on the vertical frame 13 and fixation by the fixing knob 16, the connecting seat 15 is fixed above the base 1, thereby realizing the fixation of the first vision recognition camera 4 above the conveyor belt 2. Moreover, by adjusting the fixing position of the connecting seat 15 on the vertical frame 13, the height of the first vision recognition camera 4 can be adjusted, enabling the first vision recognition camera 4 to change the distance from the patch material;

[0024] Furthermore, adjusting plates 18 are rotatably connected to the mutually remote sides of the guide plates 3. A cross plate 17 is sleeved on the outer wall of the adjusting plate 18.

[0025] In the specific implementation process, it is particularly worth noting that through the cooperation between the base 1, the guide plates 3, the cross plate 17, the adjusting plate 18, and the adjusting knob 19, by fixing the cross plate 17 and the adjusting plate 18 with the adjusting knob 19, the guide plates 3 obtain stable support. By changing the fixing depth of the adjusting plate 18 within the cross plate 17, the angle of the guide plates 3 can be adjusted, changing the distance between the two guide plates 3, enabling the guide plates 3 to accurately guide patch materials of different sizes;

[0026] Furthermore, a fixing plate 20 is provided below the fixing base 12 where the first vision recognition camera 4 is located. A lighting lamp 21 is installed at the bottom of the fixing plate 20;

[0027] In the specific implementation process, it is particularly worth noting that round holes are provided at the central positions of the fixing plate 20 and the lighting lamp 21, enabling the first visual recognition camera 4 to take images through the round holes inside the fixing plate 20 and the lighting lamp 21. Through the cooperation among the fixing base 12, the fixing plate 20 and the lighting lamp 21, by arranging the lighting lamp 21 below the first visual recognition camera 4, the material below the first visual recognition camera 4 is illuminated, enhancing the brightness of the material, making the material image information captured by the first visual recognition camera 4 clearer, and improving the recognition accuracy of the material. The specific model of the lighting lamp 21 is not limited, as long as it meets the usage requirements;

[0028] Furthermore, a servo motor 22 is fixedly connected to one side of the bottom of the base 1. Synchronous wheels 23 are provided at the output end of the servo motor 22 and on one side of the conveyor belt 2, and a synchronous belt 24 is connected to the outer wall of the synchronous wheels 23 in a matching manner;

[0029] In the specific implementation process, it is particularly worth noting that through the cooperation among the base 1, the conveyor belt 2, the servo motor 22, the synchronous wheels 23 and the synchronous belt 24, by controlling the servo motor 22 and utilizing the meshing between the synchronous wheels 23 and the synchronous belt 24, the driving of the conveyor belt 2 is achieved, thereby driving the material to move. The specific model of the servo motor 22 is not limited, as long as it meets the usage requirements;

[0030] Specifically, when using the patch discharging device that can automatically sort and remove, after the patch materials are processed, they are conveyed to the end of the top of the conveyor belt 2 far from the robotic arm 10. The conveyor belt 2 rotates under the action of the servo motor 22, driving the patch materials to move. After the patch materials come into contact with the guiding plate 3, under the action of the guiding plate 3, the patch materials are moved to the middle position of the conveyor belt 2 and continue to be conveyed and moved. When the infrared sensor 5 senses that the patch materials pass by, it transmits the sensing information to the control system. When the patch materials move to the position below the first vision recognition camera 4, the control system stops the servo motor 22. At the same time, the first vision recognition camera 4 collects images of the patch materials and transmits the collected image information to the vision recognition system in real time. The vision recognition system identifies and analyzes the image information of the patch materials. When there are quality problems with the patches, it transmits the rejection signal to the control system. After the patches are screened and recognized, the control system controls the conveyor belt 2 to continue to move and convey the patch materials. When the patches with quality problems move to the position of the rejection push plate 7, the control system automatically controls the telescopic rod of the cylinder 6 to extend, so that the rejection push plate 7 pushes the patches with quality problems out through the material guiding groove 8. After the cylinder 6 completes the rejection operation, it automatically resets to complete the screening and rejection of the patch materials. The patch materials with qualified quality continue to move under the action of the conveyor belt 2. The second vision recognition camera 9 collects images of the positions of the patch materials and transmits the position information to the control system. The control system controls the robotic arm 10 and the gripper 11 to grab the patch materials and place them into the material storage device to complete the discharging of the patches. Through the cooperation among the base 1, the conveyor belt 2, the guiding plate 3, the first vision recognition camera 4, the infrared sensor 5, the cylinder 6, the rejection push plate 7, the material guiding groove 8, the second vision recognition camera 9, the robotic arm 10 and the gripper 11, the patch materials are discharged and conveyed through the conveyor belt 2, and during the conveying process, the first vision recognition camera 4 precisely collects images of the patch materials. The vision recognition control system is used to screen, inspect and identify the patch materials, improving the accuracy and detection efficiency of the quality detection of the patch materials during discharging, and being able to automatically remove the patch materials with quality problems, realizing the rapid screening and removal of the patches, reducing the manpower, and improving the product quality and discharging efficiency of the patch materials.
