[0077] In this embodiment, before the magazine 2 is sent, the robotic arm 52 grabs the target magazine 2 in the storage box 1. Through the cooperation of the X-axis motor 44, Y-axis motor 54, and Z-axis motor 56, the robotic arm 52 grabs the magazine 2 to below the barcode scanner 6, and the barcode scanner 6 scans the QR code on the magazine 2 to obtain the logistics information of the magazine 2.

[0078] The specific working process of the above embodiment of the present invention is as follows:

[0079] Sample sending process:

[0080] The sending point sends the magazine 2 through the conveying pipeline. The magazine 2 enters the first transceiver module through the receiving end 31. At this time, the capacitive proximity switch 35 senses the arrival of a sample. The telescopic cylinder drives the transceiver cylinder 34 to move upward until the end face of the transceiver cylinder 34 is completely fitted with the end face of the conveying pipeline. The buffer air circuit connected to the bottom of the transceiver cylinder 34 works, and the magazine 2 is smoothly received into the transceiver cylinder 34. At this time, the telescopic cylinder falls back, driving the transceiver cylinder 34 to move downward. Since in the idle condition, the transfer module is located at the second end of the device, that is, the end close to the second transceiver module. After the magazine 2 in the transceiver cylinder 34 is in place, the X-axis motor 44 drives the conveying chain 42 to rotate towards the first end, and the manipulator 52 moves to the front of the first transceiver module with the magazine 2. The Y-axis motor 54 drives the manipulator to move in a direction perpendicular to the running guide rail 43, so that the manipulator 52 stops at a position where it can just grasp the magazine 2. The manipulator jaw 53 closes to clamp the magazine 2. The Y-axis motor 54 drives the manipulator 52 to move back and forth again, and the conveying chain 42 transports the manipulator 52 along the running guide rail 43 to the front of the storage box 1. The Z-axis motor 56 drives the manipulator 52 to move downward to place the magazine 2 into the storage box 1 in sequence and wait for sending. When the device receives the sending instruction, the manipulator 52 picks up the magazine 2 in the storage box 1. Under the control of the motor and the conveying chain 42, the magazine 2 is moved to below the barcode scanner 6. The Z-axis motor 56 drives the manipulator 52 to move up and down to a suitable position to perform barcode scanning on the magazine 2. The barcode scanner 6 scans the QR code information on the magazine 2 to obtain the sending logistics information of the magazine 2. The manipulator 52 transfers the magazine 2 to one of the transceiver cylinders 34 in the two second transceiver modules according to the obtained sending logistics information to prepare for sending the magazine 2. After the capacitive proximity switch 35 located on one side of the transceiver cylinder 34 senses that the magazine 2 is placed in the transceiver cylinder 34, the telescopic cylinder carried by the transceiver cylinder 34 performs an upward movement to ensure that the conveying pipeline is in a fully sealed state and at the same time ensure that the conveying gas does not leak. The main blowing circuit connected to the lower part of the transceiver cylinder 34 sends the sample, and the receiving point receives the sample sent by the conveying pipeline.

[0081] Sample return process:

[0082] The receiving point sends the sample through the conveying pipeline. Then, the capacitive proximity switch 35 senses the arrival of the sample. At this time, the receiving and sending cylinder 34 moves upward driven by the telescopic cylinder and fits completely with the conveying pipeline. The receiving and sending cylinder 34 receives the magazine 2. The manipulator 52 moves to the front of the second receiving and sending module with the magazine 2 driven by the conveying chain 42. Then, it clamps the magazine 2 driven by the Y-axis motor 54 and the Z-axis motor 56 and transfers the magazine to the storage box 1 to wait for return. When the device receives the return command, the manipulator 52 clamps the magazine 2 in the storage box 1 and moves the magazine 2 under the control of the motor and the conveying chain 42 to the scanner 6 to perform the scanning work on the magazine 2 to obtain the return logistics information of the magazine 2. The manipulator 52 transfers the magazine 2 to one of the receiving and sending cylinders 34 in the three first receiving and sending modules according to the obtained return logistics information. After the capacitive proximity switch 35 senses that the magazine 2 is placed in the receiving and sending cylinder 34, the telescopic cylinder carried by the receiving and sending cylinder 34 performs an upward movement to ensure that the conveying pipeline is in a fully sealed state. The main air blowing path connected to the lower part of the receiving and sending cylinder 34 sends the sample, and the sending point receives the sample sent by the conveying pipeline.

[0083] In the above embodiments of the present invention, by designing a modular and automated transfer receiving and sending device, the automatic sending process of nuclear material samples is made more intelligent, realizing automatic receiving and sending of samples, reducing manual intervention, simplifying the design of the sample conveying pipeline, reducing the number of receiving points, being convenient for maintenance in the glove box, saving labor and material costs, and ensuring the safety and reliability of the automatic sending process of radioactive samples.

[0084] The above is the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art of the present technology, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
