Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical canning machinery, and in particular to an automatic dispensing system for radionuclide medicine bottles. Background Technology

[0002] Radionuclide vials are specialized containers used to store or transport radionuclides (radiopharmaceuticals). These vials are primarily used in medicine for diagnostic imaging (such as PET / CT and SPECT) or radiotherapy (such as targeted therapy). The shielding material for radionuclide vials is typically a lead shell to reduce radiation leakage.

[0003] The existing automated production line for discharging radionuclide vials is a simple drawer platform structure. First, the operator pulls out the drawer platform; second, the lead canister is moved onto the drawer platform and then the drawer platform is pushed into the equipment; third, the radionuclide vial is fed into the lead canister, and finally the operator moves the lead canister to the storage area.

[0004] The area where radionuclide vials are transferred to lead containers is a high-risk operating area because radionuclide drugs are radioactive. When the lead containers are opened and closed, there is a section without lead shielding, posing a risk of radioactive leakage, which could harm the human body.

[0005] Commonly used lead containers are mostly shielded with 60mm lead. The weight of the lead container is around 50KG. Operators may experience fatigue from handling it for a long time, which can easily cause deformation and lead to accidents, resulting in radiation leakage. Utility Model Content

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0022] refer to Figure 1 As shown in the figure, this application discloses an automatic dispensing system for radionuclide vials, including a placement component 1, a transport component 2, a lead canister lid opening and closing component 3, and an input component 4. The placement component 1 includes a robot 11 and a tray 12. In this embodiment, there are two trays 12, which are respectively located on opposite sides of the robot 11. One is an incoming material tray, and the other is a finished product tray. The transport component 2 is located on one side of the robot 11. The transport component 2 includes a transport platform 21 and a power mechanism 22. The power mechanism 22 is located on the top of the transport platform 21. The lead canister lid opening and closing component 3 is located on the side of the power mechanism 22 away from the robot 11. The input component 4 for transferring radionuclide vials into lead canisters is located inside the transport platform 21.

[0023] The robot 11 is fixedly connected to the robot platform 111 at its bottom, and the robot 11 is fixedly connected to the ground through the robot platform 111.

[0024] Each pallet 12 is provided with a limiting block 121 near the robot 11. The limiting block 121 positions the pallet 12. The limiting block 121 is fixedly connected to the ground. The limiting block 121 is provided with a position sensor.

[0025] The power mechanism 22 includes a transport motor assembly 221 and a trolley 222. The power output end of the transport motor assembly 221 is connected to multiple trolleys 222. The output power causes the lead can trolleys 222 to move alternately in the circumferential direction. The spacing between adjacent trolleys is consistent. In this example, there are two trolleys 222 on the transport platform 21. The trolleys 222 stop at two positions and are used alternately. A position sensor is set at the stopping position of the trolleys 222 near the robot 11 at the top of the transport platform 21.

[0026] The lead can lid opening and closing assembly 3 includes an opening and closing assembly base 31, a horizontal moving mechanism 32, and a vertical moving mechanism 33. The opening and closing assembly base 31 is fixedly connected to the transport platform 21. The top of the opening and closing assembly base 31 is fixedly connected to the horizontal moving mechanism 32, and the top of the horizontal moving mechanism 32 is fixedly connected to the vertical moving mechanism 33. The horizontal moving mechanism 32 and the vertical moving mechanism 33 are respectively equipped with position sensors.

[0027] refer to Figure 2 As shown, the input component 4 includes a frame plate 41, a lifting device 42, and a channel 43. The lifting device 42 is located on the top and bottom surfaces of the transport platform 21. The output end of the lifting device 42 passes through the top of the transport platform 21 and is located inside the channel 43. The top of the channel 43 is fixedly connected to the frame plate 41. An opening 431 is provided at the connection between the channel 43 and the frame plate 41. A radionuclide vial is inserted through the opening 431. The lifting device 42 is equipped with a position sensor.

[0028] The input component 4 also includes a buffer device 44, the buffering end of which is located inside the channel 43 at the bottom of the opening 431. The buffer device 44 prevents the radionuclide vial from being damaged by falling. The buffer device 44 is equipped with a position sensor.

[0029] The robot 11 is equipped with a camera positioning device near its gripping part. After obtaining the signal that the pallet 12 is in place, the robot 11 controls the camera positioning device to locate the incoming pallet and the finished product pallet (the position of the lead can).

[0030] refer to Figure 3 As shown, the specific working method is as follows:

[0031] As a preferred technical solution, in this embodiment, a position sensor is installed on the limiting block 121 to detect whether the tray 12 is in place. A camera positioning device is installed on the robot 11. After obtaining the signal that the tray 12 is in place, the robot 11 controls the camera positioning device to locate the incoming material tray and the finished product tray (the position of the lead can). Finally, after receiving the signal that the trolley 222 is in place, the robot 11 performs the action of picking up and placing the lead can on the tray 12.

[0032] A position sensor is installed at the parking position of the trolley 222 on the top of the transport platform 21. After detecting that the trolley 222 is in place, the robot 11 performs the action of first picking up the lead cans from the finished product pallet and then picking up the lead cans from the incoming material pallet and placing them on the trolley 222. After the robot 11 completes the action, it sends a signal, and the transport motor assembly 221 starts to pull the trolley 222 to run until the trolley 222 is detected by the position sensor again, at which point the transport motor assembly 221 stops running.

[0033] In the lead can lid opening and closing assembly 3, the horizontal moving mechanism 32 and the vertical moving mechanism 33 are equipped with 4 sets of position sensors to detect the position signal. After obtaining the position signal of the trolley 222, the mechanism first moves horizontally to the right, then vertically upward, then horizontally to the left, and finally vertically downward. After completing the action, the lid opening completion signal is sent.

[0034] In the input component 4, the lifting device 42 is equipped with two position sensors. After receiving the signal that the opening is complete, the lifting device 42 pushes the lead can into the lead can channel 43. After it is in place, it sends a signal, and the radionuclide vial is put in from the opening 431 above the channel 43. The buffer device 44 is equipped with a position sensor to detect whether the radionuclide vial is in place and a signal indicating that the buffer device 44 is in place. After detecting the radionuclide vial, the buffer device 44 retracts, and the radionuclide vial falls down into the lead can. Then the buffer device 44 pushes out again (returns to its original position), and then the lifting device 42 resets (retracts). After it is in place, it performs the closing action.

[0035] In the lead can lid opening and closing assembly 3, the horizontal moving mechanism 32 and the vertical moving mechanism 33 are equipped with 4 sets of position sensors to detect the position signal. After obtaining the reset signal of the lifting device 42, they first move vertically upward, then horizontally to the right, then vertically downward, and finally horizontally to the left. After completing the action, a lid closing completion signal is sent.

[0036] As a preferred technical solution, in the mechanism of this embodiment, such as Figure 3 The diagram shows the complete workflow. Each tray 12 can hold 20 lead cans. Therefore, after each 20 pick-up and drop-off operations, a new tray 12 needs to be replaced. At the same time, the camera component of robot 11 needs to take a new picture of the new tray 12 and re-identify the position of the pick-up and drop-off of the lead cans (perform position positioning).

[0037] The beneficial effects are:

[0038] This utility model discloses an automatic dispensing system for radionuclide medicine bottles, which overcomes the shortcomings of the prior art and provides an automated mechanism that replaces manual operation. This system helps prevent personal injury caused by radionuclide radiation leakage in the production line and avoids existing safety hazards. The system also allows for faster and more stable handling of lead canisters, shortens the production cycle, and reduces the labor intensity of operators.
