[0049] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0050] See also Figures 1 to 4 As shown;

[0051] A sorting device according to this embodiment includes:

[0052] Rack 1;

[0053] A transmission mechanism integrated into the frame 1; and

[0054] A conveyor belt connected to the transmission mechanism, with multiple tray assemblies 2 arranged at intervals on the conveyor belt, and the tray 203 at the upper end of the tray assembly 2 is used to carry materials;

[0055] The transmission mechanism includes a driving large sprocket 101 and a driven large sprocket 102, and a transmission chain 103 that cooperates with the driving large sprocket 101 and the driven large sprocket 102. The transmission chain 103 drives the conveyor belt to move;

[0056] The driven large sprocket 102 is integrated with an identification and detection component 3;

[0057] The identification and detection component 3 is a plurality of computers 307 and a plurality of cameras 304, which are used to detect and identify the materials on each pallet 203;

[0058] 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 tilts under the action of the gravity of the material to achieve unloading.

[0059] Specifically, this embodiment discloses a novel sorting device, comprising a main frame 1 with an integrated transmission mechanism to drive a conveyor belt, thereby driving multiple tray assemblies 2. During movement, the device integrates an identification and detection component 3 on the driven large sprocket 102, which rotates with the driven large sprocket 102. Multiple computers 307 and cameras 304 operate synchronously to photograph materials on trays 203 that have moved to designated positions, identify barcode information, and transmit it via computers 307. Upon receiving information from computers 307, a single-chip microcomputer begins collecting contact switch signals and information about trays 203, beginning to count. When tray assembly 2 reaches the unloading port, an unlocking component 4 is used to release the constraints on tray 203, causing it to flip over and unload. This sorting device has a compact structure, a large number of tray assemblies 2, computers 307, and cameras 304, and high synchronous operation efficiency.

[0060] 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.

[0061] 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;

[0062] 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;

[0063] A camera bracket 303 is provided along the circumference of the top connecting ring 302 and at a position corresponding to each upright pole 301. A camera 304 is installed in the camera bracket 303, and the camera lens of the camera 304 faces downward to capture the material in the tray 203 that has moved to the corresponding position.

[0064] A fill light 305 is installed at the connection between the camera bracket 303 and the pole 301.

[0065] 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 pallet 203 at the corresponding position; the transmission chain 103 drives the pallet 203 to rotate and work in a cycle, and the camera 304 on the driven large sprocket 102 always keeps moving synchronously with the pallet 203 and keeps shooting in alignment.

[0066] First, this embodiment further defines the integrated structure and operating principle of the identification and detection component 3. Each camera 304 is equipped with a fill light 305 to ensure clear images. Each computer 307 corresponds to a camera 304, transmitting the captured images and recognized barcode information to the microcontroller for centralized processing. Specifically, the front-end camera 304 takes a picture, uploads it to the computer 307 for information recognition, and transmits it to the Arduino Mega 2560 microcontroller via USB to TTL converter. The first program sequence collects the switch signals of the contact sensor and the counting information of the tray 203 until the tray assembly 2 reaches the unloading port. The unlocking component 4 then releases the restraint, and finally completes the unloading of the materials on the tray 203, repeating the cycle. In this embodiment, multiple computers 307, cameras 304, and unlocking component 4 utilize the same operating mode, improving sorting efficiency. The camera 304 model used in this embodiment is SKT-SL1600C-123ASM12-3.

[0067] Preferably, the tray assembly 2 of this embodiment includes a tray base 201; a tray 203 connected to the tray base 201 via a tray column 202; the tray 203 is hinged to the tray column 202 via a tray shaft, and the tray 203 can be flipped forward by the tray shaft to form an inclined state, or flipped backward by the tray shaft to form a horizontal state;

[0068] 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 the inclined structure through the rotation connection of the tray shaft to maintain an angle consistent with the inclined structure;

[0069] Specifically, the rear side of the pallet column 202 of this embodiment has a hook 204, and the pallet 203 has a hanging rod 205 at the position where it cooperates with the hook 204. When transporting materials, the hook 204 is hung on the hanging rod 205 to keep the pallet 203 in a horizontal state.

[0070] In addition, the inner side of the conveyor belt of this embodiment is provided with an unlocking assembly integrated ring that cooperates with the conveyor belt, and unlocking assemblies 4 are arranged at intervals on the unlocking assembly integrated ring;

[0071] The unlocking component 4 has an electromagnet 401 controlled by a relay, and when the unlocking component 4 matches the position of the tray 203, the controller controls the relay to drive the electromagnet 401 to rise. The raised electromagnet 401 can touch the bottom of the hook 204 to drive the hook 204 to disengage from the hanging rod 205 to release the constraint of the tray 203.

[0072] The tray assembly 2 of this embodiment is equipped with an unlocking assembly 4 for use during the unloading operation after identification. Since the tray 203 is connected to the tray column 202 via a hook 204 and a hanging rod 205, the tray 203 is kept horizontal. However, when unloading, the tray 203 needs to be tilted. Therefore, the unlocking assembly 4 of this embodiment is designed. The unlocking assembly 4 is connected to the single-chip microcomputer and connected via a conductive slip ring between the active large sprocket 101, completing the electrical connection between the single-chip microcomputer and electrical components such as the electromagnet 401. Secondly, the electromagnet 401 can be raised by the action signal of the relay. When the electromagnet 401 is raised, it pushes the lower part of the hook 204, thereby driving the hook 204 to flip a certain angle and disengage from the hanging rod 205. This releases the constraint on the tray 203. The tray 203, which has materials on it, can be driven to flip under the action of gravity, completing the unloading operation.

[0073] In order to be able to reset the tray 203 after unloading the tray 203, a tray reset structure 5 is provided on one side of the unlocking assembly integrated ring of this embodiment;

[0074] The tray restoring structure 5 includes a support rod 501; and a restoring rod 502 connected to the upper end of the support rod 501 and extending obliquely;

[0075] The tray 203 in the tilted state moves from the bottom end of the reset lever 502 to the top end of the reset lever 502 to be reset by the reset lever 502 .

[0076] Preferably, the number of tray assemblies 2 of this embodiment is an integer multiple of the number of computers 307 and cameras 304; the number of links of the transmission chain 103 is an integer multiple of the number of teeth of the driving large sprocket 101.

[0077] In the above technical solution, the present invention provides a sorting device with the following beneficial effects:

[0078] The sorting device of the present invention has high integration, multiple computers 307 and cameras 304 work synchronously, thereby improving recognition efficiency and sorting efficiency, and a new tray structure is designed to improve the problem of demanding unloading port requirements.

[0079] The sorting device of the present invention increases the number of trays 203, computers 307 and cameras 304, and increases the number of items identified, transported and unloaded per unit time, thereby improving sorting efficiency. In addition, the unlocking component 4 and hook 204 driven by a relay and an electromagnet 401 are designed to facilitate unloading and resetting of the tray 203 after unloading, thereby improving the degree of automation of the device.

[0080] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
