Detailed Implementation

[0015] The following are specific implementation cases and appendices. Figure 1-4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0016] A machine vision-based scallion sorting device, such as Figure 1-4As shown, the system includes: a feeding port 10, a sorting mechanism, a primary layered conveyor, a secondary conveyor, an industrial camera 11, four screens 12, a support frame 14, and four motors 15. The feeding port 10 is located on the primary layered conveyor, and a sorting mechanism is installed inside the feeding port 10. The secondary conveyor is located on one side of the primary layered conveyor. The industrial camera 11 is installed on the secondary conveyor. The support frame 14 is located on one side of the secondary conveyor. The four screens 12 are fixed to the top of the support frame 14, and each screen has multiple rollers 13. Some of the screens 12 are located above the secondary conveyor. The four motors 15 are fixed to the bottom of the support frame 14, and the outputs of the four motors 15 are connected to the four screens 12. A discharge channel is formed between two adjacent screens 12.

[0017] Using the above structure, scallions are fed into the feeding port 10, and under the action of the sorting mechanism, the stacked scallions are sequentially sent to the primary layer conveying device. The primary layer conveying device then orderly sends the scallions to the secondary conveying device. The industrial camera 11 monitors the scallions moving on the secondary conveying device in real time and grades them according to their quality. Four motors 15 drive four screens 12 to swing, so that scallions of different grades enter the corresponding discharge channels, thereby achieving the purpose of multi-level sorting of scallions.

[0018] Specifically, when the scallions are moved by the secondary conveyor, they rub against the rollers 13 on the screener 12, causing the rollers 13 to roll and push the scallions into the designated discharge channel, thereby realizing the automated operation of automatic identification and precise sorting of scallions and improving work efficiency.

[0019] In an embodiment of this utility model, the sorting mechanism includes: a rotating shaft 16, sorting blades 17, and a sorting drive mechanism 18; the rotating shaft 16 is disposed at the bottom of the feeding port 10 and rotatably connected to the feeding port 10, and four sorting blades 17 are evenly disposed on the outer wall of the rotating shaft 16; the sorting drive mechanism 18 is disposed on one side of the primary layering transmission device, and the sorting drive mechanism 18 includes a sorting motor 181, a sorting drive wheel 182, a sorting driven wheel 183, and a sorting belt 184.

[0020] The scallions fed through the feeding port 10 fall between two adjacent sorting blades 17. The sorting motor 181 operates, and the force is guided by the sorting drive wheel 182, the sorting driven wheel 183 and the sorting belt 184, causing the rotating shaft 16 to rotate. As the sorting blades 17 are turned, multiple scallions fall sequentially onto the primary layered conveyor device.

[0022] The operation of the primary transmission motor 23 drives the primary drive wheel 24 to rotate, and through the primary belt 26, the secondary driven wheel 33 rotates accordingly, thereby driving the primary drive roller 20 to rotate, and thus enabling the layered conveyor belt 22 to rotate around the primary drive roller 20 and the primary driven roller 21.

[0023] By using the separators on the layered conveyor belt 22, the scallions falling from the sorting blades 17 are placed sequentially between two adjacent separators, thus separating the scallions and preventing them from piling up in one place and affecting the recognition effect of the subsequent industrial camera 11.

[0024] In an embodiment of this utility model, the secondary conveying device includes a secondary conveying platform 27, a secondary driving roller 28, a secondary driven roller 29, a conveyor belt 30, a secondary conveying motor 31, a secondary driving wheel 32, a secondary driven wheel 33, and a secondary belt 34.

[0027] The guide roller 36 assists in the movement of the scallions, allowing them to smoothly enter the subsequent discharge conveyor 38.

[0028] In an embodiment of this utility model, it further includes two baffles 37, which are respectively disposed on both sides of the secondary conveyor 27.

[0029] By setting two baffles 37, the scallions can be prevented from falling off during movement.

[0030] In an embodiment of this utility model, it further includes: three discharge conveying devices 38, which are respectively positioned opposite to three guide rollers 36.

An industrial camera 11 monitors the scallions moving on the secondary conveyor in real time and grades them according to their quality. Four motors 15 drive four screens 12 to swing, allowing scallions of different grades to enter their corresponding discharge channels, thus achieving multi-level sorting of the scallions. As the scallions move on the secondary conveyor, they rub against the rollers 13 on the screens 12, causing the rollers 13 to roll and push the scallions into the designated discharge channels. This achieves automated operation of automatic identification and precise sorting of scallions, improving work efficiency.
