[0027] Figures 1 to 3 An embodiment of the molybdenum-technetium generator packaging system of the utility model is shown. The molybdenum-technetium generator packaging system of this embodiment includes a shielding chamber 1, a feeding mechanism 3 for conveying the molybdenum-technetium generator 2 into the shielding chamber 1, a first conveying mechanism 5 for conveying a protective container 4 (such as a lead barrel) into the shielding chamber 1, and a transfer robot 6 that can transfer the protective container 4 to the inside of the shielding chamber 1. The shielding chamber 1 is provided with an activity detection mechanism 7 (such as an activity well), a material taking robot 8, and a cover taking and capping robot 9. It should be noted that in order to clearly show the structure of each component in the shielding chamber 1, Figure 2 and Figure 3 Part of the wall surface of the middle shielding chamber 1 is hidden.

[0028] In the molybdenum-technetium generator packaging system of this embodiment, the filled molybdenum-technetium generator 2 is conveyed to the shielding chamber 1 by the feeding mechanism 3, the material taking robot 8 grabs the molybdenum-technetium generator 2 and transfers it to the activity detection mechanism 7 for activity detection. At the same time, the empty protective container 4 is conveyed by the first conveying mechanism 5 to the vicinity of the shielding chamber 1, the transfer robot 6 grabs the empty protective container 4 and transfers it to the shielding chamber 1, the cover taking and capping robot 9 opens the upper cover of the protective container 4, and after the activity detection is completed, the material taking robot 8 transfers the molybdenum-technetium generator 2 to the protective container 4, and the cover taking and capping robot 9 presses the upper cover back into the protective container 4, thereby completing the inner packaging process of the molybdenum-technetium generator 2, with a high degree of automation and efficiency, which is conducive to reducing the risk of contamination.

[0029] Preferably, the feeding mechanism 3, the first conveying mechanism 5 and the second conveying mechanism 18 mentioned below can be, for example, a commonly used conveyor belt, and a support plate with positioning holes can be provided on the conveyor belt of the feeding mechanism 3 to keep the molybdenum-technetium generator 2 stable during the conveying process; Figure 1 The transfer robot 6, the material picking robot 8 and the cover removing and capping robot 9 can grab the protective container 4, the upper cover of the protective container 4 or the molybdenum-technetium generator 2 by means of claws, vacuum suction cups, etc. The transfer robot 6 has sliding, rotating and telescopic functions, which is convenient for driving the protective container 4 to transfer between the first conveying mechanism 5, the shielding chamber 1 and the second conveying mechanism 18. The material picking robot 8 has rotation and lifting functions, which is convenient for placing the molybdenum-technetium generator 2 into the activity well and taking it out from the activity well and putting it into the protective container 4. The cover removing and capping robot 9 only needs to have the lifting function to realize cover removing and capping. Compared with the screwing cover, the capping method can simplify the structure of the cover removing and capping robot 9 and reduce the cost.

[0030] Furthermore, in this embodiment, the shielding chamber 1 includes an activity detection area 10, a finished product discharge area 11 located below the activity detection area 10, and a partition door 12 arranged between the activity detection area 10 and the finished product discharge area 11, the feeding mechanism 3 is docked with the activity detection area 10, the activity detection mechanism 7, the material taking manipulator 8 and the cover taking and capping manipulator 9 are arranged in the activity detection area 10, the finished product discharge area 11 is provided with a finished product discharge device 13, and the first conveying mechanism 5 is docked with the finished product discharge area 11. The cleanliness of the surface of the protective container 4 is lower than that of the molybdenum-technetium generator 2. The partition door 12 is used to separate the shielding chamber 1 into the activity detection area 10 and the finished product discharge area 11, and the finished product discharge area 11 is located below the activity detection area 10, which is conducive to reducing the risk of contamination of the activity detection area 10, and at the same time facilitates the molybdenum-technetium generator 2 to be placed from top to bottom into the protective container 4, and the layout is reasonable. Before the cover taking and capping manipulator 9 takes the upper cover, the partition door 12 is opened. The molybdenum-technetium generator 2 is placed in the protective container 4. After the cover-taking and cover-pressing robot 9 presses the upper cover into the protective container 4, the partition door 12 is closed.

[0031] As a preferred embodiment, the activity detection mechanism 7 is arranged at the lower side of the activity detection area 10, so as to facilitate the material taking robot 8 to place the molybdenum-technetium generator 2 into the activity detection mechanism 7 from top to bottom.

[0032] Furthermore, in this embodiment, the activity detection area 10 is provided with a first scanning component 14 for scanning the molybdenum-technetium generator 2, and the finished product discharge area 11 is provided with a second scanning component 15 for scanning the protective container 4.

The protective container 4 is transmitted to the transfer robot 6 through the first conveying mechanism 5. The transfer robot 6 grabs the empty protective container 4 and puts it into the container placement portion 16. The second scanning component 15 scans the QR code on the protective container 4 and matches it with the information scanned by the first scanning component 14. The protective container 4 is driven by the moving mechanism 17 to the bottom of the partition door 12, and the lifting mechanism lifts the protective container 4 to a certain height to facilitate receiving the molybdenum-technetium generator 2. The structure is reasonable and effective. Among them, the moving mechanism 17 can be a mechanism such as a cylinder, an oil cylinder or a screw nut pair to drive the moving seat to move along the guide rail. A lifting seat is arranged on the moving seat. The lifting and lowering of the lifting seat has the same principle as the movement of the moving seat, but the direction is different, which will not be repeated.

After being in place, the transfer robot 6 grabs the protective container 4 and transfers it to the second conveying mechanism 18, which is convenient for subsequent processes.

[0036] Furthermore, in this embodiment, the second conveying mechanism 18 is provided with a radiation detection station 19 and a capping detection station 20. The radiation detection station 19 can perform an external radiation detection on the protective container 4 receiving the molybdenum-technetium generator 2 to prevent leakage; the capping detection station 20 can detect whether the upper cover is properly pressed.

[0037] Furthermore, in this embodiment, the second conveying mechanism 18 is provided with a labeling station 21 and a labeling inspection station 22 located downstream of the labeling station 21. The labeling station 21 labels the protective container 4, and the labeling inspection station 22 inspects the labeling effect. Finished products with unqualified labeling can be rejected by execution components such as a rejection cylinder to the rejection station 23, and qualified products continue to flow downward to the outer packaging station 24.

[0038] As a preferred embodiment, the first conveying mechanism 5 and the second conveying mechanism 18 are arranged in parallel, and the transfer robot 6 is disposed between the first conveying mechanism 5 and the second conveying mechanism 18. The overall layout is reasonable and compact, and occupies little space, which facilitates the transfer robot 6 to transfer the protective container 4 between the first conveying mechanism 5 and the second conveying mechanism 18.
