[0074] The robotic arm 3 includes a support frame 301, a rotating frame 302, a lower clamping fork 303, and an upper clamping fork 304. A rotating disk 3011 is provided between the support frame 301 and the rotating frame 302. A third motor 3049 drives the rotating disk 3011 to rotate, thereby realizing the rotation of the rotating frame 302. A track 3021 is provided on the rotating frame 302. The lower groove 3041 of the upper clamping fork 304 is connected to the track 3021. A rotating wheel 3012 is provided at one end of the rotating disk 3011. A fourth motor 3014 is connected to the rotating wheel 3012 through a third transmission belt 3013. The upper clamping fork 304 is fixed on the third transmission belt 3013, so that the upper clamping fork 304 can move along the track 3021.

[0075] The upper clamping fork 304 is provided with a guide post 3042, and a downward pressure spring 3043 is provided on the guide post 3042. The lower clamping fork 303 passes through the guide post 3042. The lower clamping fork 303 is pushed open by the downward pressure spring 3043, thereby separating the lower clamping fork 303 from the upper clamping fork 304.

[0076] The fifth motor 3044 is fixedly mounted on the upper clamping fork 304 via the upright plate 3045. An eccentric wheel 3046 is provided on the output shaft of the fifth motor 3044, and a driven block 3047 is provided on the lower clamping fork 303. An eccentric hole 3048 is provided on the driven block 3047. The eccentric wheel 3046 cooperates with the eccentric hole 3048 to lift the lower clamping fork 303.

[0077] A rotating disk 3011 is installed between the support frame 301 and the rotating frame 302. A third motor 3049 drives the rotating disk 3011 to rotate, thereby rotating the rotating frame 302 to adjust the angle for gripping and placing the bill of lading. A track 3021 is installed on the rotating frame 302. The upper clamping fork 304 is connected to the track 3021 via a lower groove 3041. A fourth motor 3014 connects to the rotating wheel 3012 and the third transmission belt 3013, allowing the upper clamping fork 304 to move along the track 3021, with the lower clamping fork 303 following suit. The upper clamping fork 304 is equipped with guide posts. 3042 and a pressure spring 3043, the lower clamping fork 303 passes through the guide post 3042, and the lower clamping fork 303 is springed open by the pressure spring 3043, thus separating the lower clamping fork 303 from the upper clamping fork 304; the fifth motor 3044 is fixed on the upper clamping fork 304 through the upright plate 3045, and the eccentric wheel 3046 on its output shaft cooperates with the eccentric hole 3048 of the driven block 3047 on the lower clamping fork 303 to lift the lower clamping fork 303. Through this clamping fork structure, the bill of lading can be flexibly gripped and released, adapting to bills of lading of different thicknesses and materials, and ensuring the reliability of operation.

[0078] During the order retrieval process, the lower clamping fork 303 and the upper clamping fork 304 are in a spring-loaded state. The upper clamping fork 304 moves along the guide rail, moving the lower clamping fork 303 forward. The lower clamping fork 303 is inserted into the lower part of the hollow space in the M-shaped structure, and the upper clamping fork 304 is inserted from the top. The eccentric wheel 3046 rotates, lifting the lower clamping fork 303 onto the platform and clamping the bill of lading between the upper and lower clamping forks 303. The upper clamping fork 304 then drives the lower clamping fork 303 to move backward, and the rotating frame 302 rotates to complete the directional adjustment of the robot arm 3. The robot arm 3 moves to the designated position under the action of the forward and backward moving component 31 and the up and down moving component 32. When the robot arm 3 places the bill of lading on the order retrieval unit 21 or the shelf 42, the same placement process is performed. After the robotic arm 3 places the bill of lading on the delivery shelf 42, the upper and lower clamping forks 303 are adjusted to the correct height and only perform a forward pushing motion to push the bill of lading into the delivery box 41.

[0079] The shipping mechanism 4 includes a shipping container 41 and a shipping shelf 42. A robotic arm 3 places the bill of lading on the shipping shelf 42, and then uses its upper clamping fork 304 to retract the bill of lading into the shipping container 41. The customer can then retrieve the bill of lading from the shipping container 41. A detection sensor is installed inside the shipping container 41 to detect whether a bill of lading is present. The robotic arm 3 places the bill of lading on the shipping shelf 42, and then uses its upper clamping fork 304 to retract the bill of lading into the shipping container 41. The customer can then retrieve the bill of lading from the shipping container 41, completing the bill of lading retrieval process. The detection sensor inside the shipping container 41 is used to detect whether a bill of lading is present in the shipping container 41, so as to provide timely feedback on the bill of lading's shipping status.

[0080] The bill of lading machine is also equipped with an outer casing 5 to protect the internal structure and bill of lading materials; an interactive panel 51 is located on the front of the device, and a delivery port 52 is located below the interactive panel 51 for interaction with customers; a sliding door 53 is installed on the outside of the bill of lading storage rack 1. During the bill of lading storage process, the staff needs to push open the sliding door and place the bill of lading on the bill of lading storage rack 1.

[0081] In practical applications, when a bill of lading needs to be deposited, the staff places the bill of lading into the deposit unit 11 of the bill of lading deposit rack 1. The robotic arm 3 moves the bill of lading from the deposit unit 11 to the identification area 13. The bill of lading identification module 12 identifies the bill of lading number and records relevant information. The robotic arm 3 moves to the corresponding deposit unit 11 position of the bill of lading deposit rack 1 via the forward and backward moving component 31 and the up and down moving component 32, and uses the gripping components (lower clamping fork 303 and upper clamping fork 304) to grab the bill of lading. Then, the bill of lading is transferred from the identification area 13 to the corresponding waiting unit 21 of the bill of lading waiting rack 2. When the bill of lading needs to be retrieved, the robotic arm 3, according to the location number of the bill of lading, moves again to the corresponding position of the bill of lading waiting rack 2 via the forward and backward moving component 31 and the up and down moving component 32, grabs the bill of lading, and transfers it to the dispatch rack 42 of the dispatching mechanism 4. Finally, the robotic arm 3 pushes the bill of lading into the dispatch box 41, and the customer takes the bill of lading from the dispatch box 41, completing the bill of lading retrieval process.

[0082] This utility model of bill of lading machine achieves efficient and accurate storage and retrieval of bills of lading through the coordinated work of its various components, solving many problems existing in traditional bill of lading management methods and showing good application prospects.

[0083] The operational process includes the process of staff depositing orders and the process of customers retrieving orders.

[0084] During the deposit process, bills of lading are manually placed in batches into deposit unit 11. Driven by the forward and backward moving component 31 and the up and down moving component 32, the robotic arm 3 takes out the bills of lading from the deposit unit 11 and places them into the recognition area 13. The bill of lading recognition module 12, i.e., the camera, at the top of the recognition area 13 takes a picture of the bill of lading and recognizes the barcode or QR code on it. The system assigns a waiting unit 21, and the robotic arm 3 puts the bill of lading into the assigned waiting unit 21.

[0085] During the order retrieval process, the customer scans a code to identify or reads the bill of lading information to be retrieved by entering their ID card or mobile phone number. The system issues instructions to the robotic arm 3, which moves to the corresponding order retrieval unit 21 driven by the forward and backward moving component 31 and the up and down moving component 32. The robotic arm 3 retrieves the bill of lading and transports it to the delivery shelf 42. The robotic arm 3 pushes the bill of lading from the delivery shelf 42 into the delivery box 41, and the customer takes the bill of lading from the delivery box 41.
