[0034] The conversion device 2 is provided with a plurality of devices, which are connected to the fluoride ion receiving bottle 13 through a pipeline. The conversion device 2 includes a three-way pipe 21 connected to the pipeline, a conversion head 22 for controlling the opening and closing of different valves of the three-way pipe 21, and a first driving component 23 connected to the conversion head 22.

[0035] During use, the fluoride ions are first introduced into the fluoride ion receiving bottle 13. At this time, the staff specifies the amount (volume) of fluoride ions, which are extracted through the syringe 4. The valve direction of the three-way pipe 21 is adjusted through the conversion device 2 to send the fluoride ions to the target shooting device 5. The fluoride ions are then adjusted through the three-way pipe 21 and passed into the synthesizer 6. The fluoride ions are then passed into the designated synthesizer 6 for synthesis. The remaining fluoride ions in the fluoride ion receiving bottle 13 can be passed into other synthesizers 6 through the three-way pipe 21 for synthesis of other drugs. This operation avoids repeated shooting, has a compact structure, and reduces the floor space required for the device, so that it can adapt to more experimental environments.

[0036] Reference Figure 2 and Figure 3The first drive assembly 23 is installed on the device body 1. The first drive assembly 23 includes a first drive motor 231 installed in the device body 1 and a valve seat 232 installed on the output shaft of the first drive motor 231. The conversion head 22 is fixed to the valve seat 232. A mounting plate 233 is installed inside the device body 1. A plurality of first drive motors 231 are installed on the mounting plate 233 at intervals. The first drive motor 231 is fixed to the mounting plate 233 by bolts 3.

[0037] The mounting plate 233 serves as a supporting structure, providing a stable mounting platform for the first drive motor 231, ensuring the stability and safety of the first drive motor 231 during operation. Multiple first drive motors 231 are spaced apart, and air circulates between the motors, improving heat dissipation efficiency, avoiding damage to the motor due to overheating, and extending the service life of the motor. The first drive motor 231 is fixed to the mounting plate 233 by bolts 3, which not only ensures the firm installation of the motor, but also provides the possibility of adjusting the position of the motor, facilitating the installation, disassembly and maintenance of the motor.

[0038] The first drive motor 231 is used as a power source. Through the connection between its output shaft and the valve seat 232, the motor's rotational power is transmitted to the valve seat 232, thereby controlling the rotation of the conversion head 22 to achieve valve conversion of the three-way pipe 21. Through the precise control of the first drive motor 231, the valve seat 232 and the conversion head 22 can be precisely controlled and positioned to ensure the accuracy and stability of the equipment operation.

[0039] A bearing 7 is arranged outside each valve seat 232, and the bearing 7 drives the valve seat 232 and the conversion head 22 to rotate concentrically. The use of the bearing 7 significantly reduces the friction between the valve seat 232 and the conversion head 22 during the rotation process, reduces wear, and prolongs the service life of the equipment. In order to ensure a concentric rotation, the accuracy of the rotation is guaranteed. At the same time, the low friction characteristics of the bearing 7 improve the rotation efficiency, making the rotation of the valve seat 232 and the conversion head 22 smoother and reducing energy loss.

[0040] Reference Figure 2 and Figure 3 The device body 1 is also provided with a pulling device 8 for driving the syringe 4 to extract fluoride ions. The pulling device 8 includes a lifting assembly 81 provided in the device body 1 and a second driving assembly 82 driving the lifting assembly 81 to lift. The lifting assembly 81 includes a lead screw 811 connected to the second driving assembly 82 and a moving block 812 passing through the lead screw 811. The moving block 812 is connected to the injection push rod of the syringe 4.

[0041] When in use, the second drive assembly 82 controls the rotation of the lead screw 811 by connecting with the lead screw 811, and the lead screw 811 converts the rotational motion into the linear motion to realize the up and down movement of the moving block 812, so that the advancement and retreat of the injection push rod can be accurately controlled, thereby realizing accurate control of the syringe 4. Through the accurate control of the second drive assembly 82, the position of the moving block 812 can be accurately adjusted, and then the injection volume and injection speed of the syringe 4 can be accurately controlled.

[0042] The use of the pulling device 8 realizes the automated operation of extracting fluoride ions from the syringe 4, reduces the need for manual operation, and improves the efficiency and safety of the operation. Through the precise control of the pulling device 8, the amount of fluoride ions extracted from the syringe 4 can be precisely controlled to ensure the accuracy and consistency during the experiment or production process. The combination of automated operation and precise control significantly improves the efficiency of the experiment or production process, reduces the operation time, improves the overall work efficiency, and reduces the risk of contamination that may be introduced during the operation.

[0043] The second driving assembly 82 includes a fixed plate 821 connected to the inner wall of the device body 1, a second driving motor 822 inserted through the fixed plate 821, a driving wheel 823 inserted through the output shaft of the second driving motor 822, and a driven wheel 824 meshed with the driving wheel 823 via a pulley (not shown in the figure), and the driven wheel 824 is inserted through the lead screw 811.

[0044] When in use, the second drive motor 822 is driven, and the output shaft of the second drive motor 822 drives the driving wheel 823 to rotate, and the driving wheel 823 drives the driven wheel 824 to rotate through the belt, and the driven wheel 824 drives the screw 811 to rotate, so that the sliding block can slide along the screw 811, thereby pulling the injection push rod of the syringe 4, thereby realizing the transfer of fluoride ions.

[0045] The second drive motor 822 is electrically connected to a controller (not shown in the figure), and the controller is also connected to the target shooting device 5 and the synthesizer 6. The multiple controllers are electrically connected to the touch screen 9. Due to the large number of points, the touch screen 9 is selected as the host computer control. The touch screen 9 can well interact with the user and display the operation status of the equipment. At the same time, considering that there are two production areas (target shooting device 5 and synthesizer 6), two touch screens 9 are selected and installed in the two production areas to realize partition control. During operation, the staff clicks on the touch screen 9 to issue a command, and the controller controls the synthesizer 6, the target shooting device 5 and the second drive motor 822 to start moving respectively to realize the switching of fluoride ions.

[0047] When the second drive motor 822 drives the active wheel 823 to rotate, and the active wheel 823 drives the driven wheel 824 to rotate, the moving block 812 moves along the length direction of the screw 811, so that the moving block 812 moves along the guide rail at the same time. The guide rod 10 can limit the path of the moving block 812 to avoid slight rotation of the moving block 812 during the movement, thereby ensuring the push-pull accuracy of the syringe 4. The end of the guide rod 10 is connected to the fixed plate 821, which further increases the fixing strength of the guide rod 10.

[0049] By providing the first reinforcement plate 11 and the second reinforcement plate 12 at both ends of the guide rod 10, the structural stability of the guide rod 10 can be significantly improved, and deformation or damage caused by uneven force or vibration during the operation of the device can be prevented. The connection between the guide rod 10 and the moving block 812 and the fixed plate 821 is strengthened by the second reinforcement plate 12, ensuring the strength of the connection part and avoiding equipment failure caused by loose connection or insufficient strength. The connection design between the second reinforcement plate 12 and the top of the screw 811 optimizes the force transmission path, so that the screw 811 can more smoothly transmit force to the guide rod 10 when rotating, thereby improving the accuracy and efficiency of the equipment operation.

[0050] The implementation principle of a fluoride ion switching device in an embodiment of the present application is as follows: when in use, fluoride ions are first introduced into the fluoride ion receiving bottle 13. At this time, the staff specifies the amount of fluoride ions (volume). The output shaft of the second drive motor 822 drives the driving wheel 823 to rotate. The driving wheel 823 drives the driven wheel 824 to rotate through the belt. The driven wheel 824 drives the lead screw 811 to rotate, so that the sliding block can slide along the lead screw 811, thereby pulling the injection push rod of the syringe 4. The second drive component 82 controls the rotation of the lead screw 811 by connecting with the lead screw 811. The lead screw 811 converts the rotational motion into linear motion to realize the up and down movement of the moving block 812. The first drive motor 231 transmits the rotational power of the motor to the valve seat 232 through the connection between its output shaft and the valve seat 232, thereby controlling the rotation of the conversion head 22 to realize the switching of fluoride ions.
