[0059] The transmission mechanism can drive the hook 204 of the tray assembly 3 to move to release the constraint of the tray 203, and the tray 203 is tilted under the action of the gravity of the material to achieve unloading.

[0060] Specifically, this embodiment discloses a novel sorting device, the main body of which is a frame 1, and a transmission mechanism is integrated on the frame 1 to drive the conveyor belt to move continuously, thereby driving multiple tray assemblies 2 to move. During movement, the device of this embodiment integrates an identification and detection component 3 that rotates with the driven large sprocket 102 on the driven large sprocket 102, and uses multiple computers 307 and cameras 304 to work synchronously, taking photos of the materials on the tray 203 that moves to the specified position to identify the barcode information and transmit it through the computer 307. The single-chip microcomputer receives the information from the computer 307, starts to collect contact switch signals, and collects the information of the tray 203 to start counting. When the tray assembly 2 runs to the unloading port, the unlocking component 4 is used to release the constraint of the tray 203, and the tray 203 is flipped to realize unloading. The sorting device has a compact structure, a large number of tray assemblies 2, computers 307, and cameras 304, and high synchronous operation efficiency.

[0061] Preferably, a driving motor is integrated in the frame 1 of this embodiment, and the output end of the driving motor is connected to the driving large sprocket 101 to drive the driving large sprocket 101 to rotate.

[0062] Preferably, a plurality of chassis 306 are provided on the driven large sprocket 102 of this embodiment, and a computer 307 is placed on the chassis 306;

[0063] The driven large sprocket 102 is connected to a plurality of vertical rods 301 along its circumferential direction, and a top connecting ring 302 is fixed to the upper end of the plurality of vertical rods 301;

[0065] A fill light 305 is installed at the connection between the camera bracket 303 and the pole 301.

[0066] The driven large sprocket 102 of this embodiment drives the computer 307 and the camera 304 thereon to rotate so as to sequentially photograph and identify the materials on the tray 203 at the corresponding position;

[0067] The transmission chain 103 drives the tray 203 to rotate and work in a cycle, and the camera 304 on the driven large sprocket 102 always keeps moving synchronously with the tray 203 and keeps aiming for shooting.

[0068] First, this embodiment further defines the integrated structure and working principle of the identification and detection component 3, and is equipped with a fill light 305 for each camera 304 to ensure the clarity of the captured image; each computer 307 corresponds to a camera 304, so that the captured image and the identified barcode information are transmitted to the single-chip microcomputer for centralized processing.

In this embodiment, multiple computers 307, cameras 304 and unlocking components 4 adopt the same working mode to improve sorting efficiency. The model of the camera 304 in this embodiment is selected

[0071] The connection between the tray column 202 and the tray 203 is designed as an inclined structure. After the tray 203 is released from the constraint, it can be turned toward one side of the inclined structure through the rotation connection of the tray shaft to maintain an angle consistent with the inclination angle of the inclined structure;

Secondly, the electromagnet 401 can rise under the action signal of the relay. When the electromagnet 401 rises, it can push the lower part of the hook 204 to drive the hook 204 to flip a certain angle and disengage from the hanging rod 205, so that the constraint on the tray 203 is released. There is material on the tray 203, and the tray 203 can be driven to flip under the action of gravity to complete the unloading operation.

[0076] In order to reset the tray 203 after the tray 203 is unloaded, a tray reset structure 5 is provided on one side of the integrated ring of the unlocking assembly of this embodiment;

[0077] The tray resetting structure 5 includes a support rod 501; and a resetting rod 502 connected to the upper end of the support rod 501 and extending obliquely;

[0078] The tray 203 in the tilted state moves from the bottom end of the reset rod 502 to the top end of the reset rod 502 to be reset by the reset rod 502 .

[0079] Preferably, the number of tray assemblies 2 of the present embodiment is an integer multiple of the number of computers 307 and cameras 304; the number of sections of the transmission chain 103 is an integer multiple of the number of teeth of the driving large sprocket 101.

[0081] The sorting device of the present invention has high integration, multiple computers 307 and cameras 304 work synchronously, which improves the recognition efficiency and sorting efficiency, and designs a new tray structure to improve the problem of demanding requirements on the unloading port.

[0082] The sorting device of the present invention increases the number of trays 203, computers 307 and cameras 304, increases the number of items identified, transported and unloaded per unit time, and improves the sorting efficiency; and an unlocking component 4 and a hook 204 driven by a relay and an electromagnet 401 are designed, which can facilitate the unloading of items from the tray 203 and the resetting after unloading, thereby improving the degree of automation of the device.
