[0027] Combine the following Figure 1-Figure 6 The utility model describes an automated preparation system for radioactive capsules.

[0028] like Figure 1 As shown, in an embodiment of the utility model, the automated preparation system of radioactive capsules includes: a rotating device 100, a feeding device 10, a separating device, a filling device 30, a drug solution dripping device 40 and a capsule closing device 50. The rotating device 100 includes a material tray 101 and a push rod 102. The material tray 101 is provided with a plurality of material holes 1011 in a ring shape. Each material hole 1011 is provided with a push rod 102. A receiving block 103 is provided at one end of each push rod 102. The receiving block 103 is provided with a receiving hole 1031. The push rod 102 can drive the receiving block 103 to move so that each receiving hole 1031 is aligned with or staggered with a material hole 1011. The unloading device 10 is used to transport the empty capsule shells to the receiving hole 1031 and the material hole 1011. The separating device is arranged below the material tray 101. The separating device is used to separate the empty capsule shells so that the capsule body 401 is received in the material hole 1011 and the capsule cap 402 is received in the receiving hole 1031. The filling device 30 is used to fill capsule powder into the capsule body 401, the liquid medicine dripping device 40 is used to drip radioactive liquid medicine into the capsule body 401, and the capsule closing device 50 is used to fit the capsule cap 402 and the capsule body 401, wherein the material tray 101 can rotate to drive the material hole 1011 to move to the feeding device 10, the filling device 30, the liquid medicine dripping device 40 and the capsule closing device 50 in sequence. When the material hole 1011 is located at the feeding device 10 and the capsule closing device 50, the material hole 1011 is aligned with the receiving hole 1031, and when the material hole 1011 is located at the filling device 30 and the liquid medicine dripping device 40, the material hole 1011 is staggered with the receiving hole 1031.

[0029] Specifically, if Figure 2As shown, the rotating device 100 includes: a material tray 101, a plurality of push rods 102 and a third motor 104. The third motor 104 is used to drive the material tray 101 to rotate. The material tray 101 is provided with a plurality of material holes 1011 in a ring shape along its circumferential direction. Each material hole 1011 is provided with a push rod 102 correspondingly. A receiving block 103 is provided at one end of each push rod 102. The receiving block 103 is provided with a receiving hole 1031. Both the receiving hole 1031 and the material hole 1011 are through holes. A rotary pneumatic joint is installed at the center of the material tray 101 to provide power for the push rod 102 to extend and retract. When the push rod 102 is extended and retracted, it can drive the receiving block 103 to move so that the receiving hole 1031 is aligned or staggered with the material hole 1011. Optionally, in an embodiment of the utility model, the third motor 104 is a rotary servo motor.

[0030] In actual operation, first, the third motor 104 rotates to rotate any material hole 1011 to the position where the unloading device 10 is located, and the push rod 102 drives the accommodating block 103 to move so that the accommodating hole 1031 is aligned with the material hole 1011. The unloading device 10 unloads the empty capsule shell into the accommodating hole 1031 and the material hole 1011. At this time, the capsule body 401 and the capsule cap 402 are in a nested state. In this embodiment, the separation device and the unloading device 10 are in the same position, and the separation device is located below the material tray 101. A part of the separation device extends into the material hole 1011 and is attracted to the capsule body 401, and then this part moves in a direction away from the capsule cap 402, thereby separating the capsule body 401 from the capsule cap 402. After separation, the capsule body 401 is located in the material hole 1011, and the capsule cap 402 is located in the accommodating hole 1031.

[0031] The third motor 104 drives the material tray 101 to rotate to the position where the filling device 30 is located, and the push rod 102 contracts to stagger the capsule cap 402 and the capsule body 401. The capsule body 401 is aligned with the filling device 30, and the capsule powder enters the capsule body 401 from the filling device 30.

[0032] The third motor 104 drives the material tray 101 to continue rotating to the position where the liquid medicine dripping device 40 is located, and the liquid medicine dripping device 40 drips the radioactive liquid medicine into the capsule body 401. Then, the third motor 104 drives the material tray 101 to rotate to the position where the capsule closing device 50 is located, and the push rod 102 drives the accommodation block 103 to move, so that the accommodation hole 1031 is aligned with the material hole 1011 again, that is, the capsule cap 402 is aligned with the capsule body 401 filled with capsule powder and radioactive liquid medicine. The capsule closing device 50 pushes the capsule body 401 to move upward, thereby making the capsule body 401 and the capsule cap 402 fit together.

[0033] The automated preparation system for radioactive capsules provided by the embodiment of the utility model realizes automatic transportation and separation of empty capsule shells, filling of capsule powder into capsule bodies, dripping of radioactive liquid medicine and automatic capsule closing by arranging a rotating device, a feeding device, a separating device, a filling device, a liquid medicine dropping device and a capsule closing device, thereby realizing fully automated preparation of radioactive capsules, having high production efficiency and a high qualified rate of reflective capsules, and at the same time reducing the radiation to which operators are exposed during the production process.

[0034] Furthermore, in the embodiment of the present utility model, the automated preparation system for radioactive capsules has a total of 6 preparation stations, and each station is described in detail one by one in the order of the stations.

[0035] like Figure 3 As shown, the feeding device 10 comprises: a first bracket 11, a first funnel 12, a driving mechanism and a pressing mechanism. The first funnel 12 is arranged on the first bracket 11, and the first funnel 12 is used to convey the empty capsule shell. The driving mechanism is arranged on the first bracket 11, and the driving mechanism is used to push part of the capsule body 401 into the receiving hole 1031, and the pressing mechanism is used to press the empty capsule shell into the receiving hole 1031 and the material hole 1011.

[0036] Specifically, the unloading station is the first station of the automated preparation system, and the unloading station is provided with an unloading device 10. The first funnel 12 is connected to a conveying pipe 13, and the first funnel 12 contains empty capsule shells, which are conveyed to the connecting plate of the first bracket 11 by the first funnel 12 and the conveying pipe 13, and abut against the driving mechanism, and the driving mechanism pushes the empty capsule shells to move onto the accommodating block 103, and part of the capsule body 401 automatically falls into the accommodating hole 1031, and the pressing mechanism moves downward to press the empty capsule shells into the accommodating hole 1031 and the material hole 1011.

[0037] Further, in the embodiment of the utility model, the driving mechanism includes: a first driving member 14 and a guide block 15. The first driving member 14 is disposed on the first bracket 11, and the first driving member 14 is retractable. The guide block 15 is connected to the first driving member 14, and the guide block 15 is used to guide the empty capsule shell, so that under the push of the first driving member 14, part of the capsule body 401 can fall vertically into the receiving hole 1031. The pressing mechanism includes: a fourth driving member 16 and a second ejector pin 17, and the fourth driving member 16 is used to drive the second ejector pin 17 to move, and the second ejector pin 17 is used to press the empty capsule shell into the receiving hole 1031 and the material hole 1011.

[0038] Specifically, in this embodiment, the receiving hole 1031 is aligned with the material hole 1011, and the empty capsule shells can be discharged one by one by the first funnel 12 and the conveying pipe 13. After being conveyed out by the conveying pipe 13, the empty capsule shells fall onto the connecting plate of the first bracket 11, and the side of the empty capsule shells abuts against the guide block 15. The guide block 15 is used to guide the empty capsule shells so that the empty capsule shells are perpendicular to the connecting plate. The first driving member 14 pushes the guide block 15 to move, pushes the empty capsule shells onto the receiving block 103, and then makes part of the empty capsule shells fall into the receiving hole 1031. The fourth driving member 16 drives the second ejector pin 17 to move downward, and the second ejector pin 17 abuts against the empty capsule body, pushing the entire empty capsule body into the receiving hole 1031 and the material hole 1011.

[0039] Furthermore, the unloading device 10 is the first station of the automated preparation system, at which not only the unloading of empty capsule shells is realized, but also the separation of empty capsule shells is realized. The separation device includes: a second driving member 71 and a first suction cup 72. The second driving member 71 is arranged below the material tray 101, and the first suction cup 72 is connected to the second driving member 71. The second driving member 71 is used to drive the first suction cup 72 to move in a direction close to the capsule body 401 so as to be sucked with the capsule body 401; the second driving member 71 is also used to drive the first suction cup 72 to move in a direction away from the capsule cap 402 after the first suction cup 72 is sucked with the capsule body 401, so as to separate the capsule body 401 from the capsule cap 402.

[0040] Specifically, after the empty capsule shell is located in the receiving hole 1031 and the material hole 1011, the second driving member 71 drives the first suction cup 72 to move upward, and after the first suction cup 72 abuts against the capsule body 401, it is sucked together with the capsule body 401, and the second driving member 71 drives the first suction cup 72 to move downward, thereby separating the capsule body 401 from the capsule cap 402. After separation, the capsule body 401 is located in the material hole 1011, and the capsule cap 402 is located in the receiving hole 1031. Then, the push rod 102 contracts, driving the receiving block 103 away from the material hole 1011, so that the capsule cap 402 is away from the capsule body 401.

[0041] like Figure 4 As shown, the second station of the automated preparation system is a rejection station, and the rejection station is provided with a rejection device 20, which is used to reject unseparated empty capsule shells. The rejection device 20 includes: a plurality of photoelectric sensors 21, an ejection mechanism and a suction pipe 24. The plurality of photoelectric sensors 21 are arranged above the material tray 101, and the plurality of photoelectric sensors 21 are respectively used to detect the capsule body 401 and the capsule cap 402. The ejection mechanism is arranged below the material tray 101, and the ejection mechanism is used to eject the unseparated empty capsule shells. The suction pipe 24 is arranged above the material tray 101, and the suction pipe 24 is used to cooperate with the ejection mechanism to eject the unseparated empty capsule shells out of the receiving hole 1031.

[0042] Specifically, in the process of the separation device separating the capsule body 401 from the capsule cap 402, since the capsule cap 402 has no fixing device, for the partially tightly fitted empty capsule body, when the second driving member 71 moves downward, the empty capsule shell may be driven to move downward as a whole, so that the empty capsule shell cannot be separated. Two photoelectric sensors 21 are arranged above the material tray 101. When one of the two photoelectric sensors 21 detects the capsule cap 402 and the other detects the capsule body 401, it indicates that the capsule body 401 is separated from the capsule cap 402; when one of the photoelectric sensors 21 detects the capsule cap 402 and the other photoelectric sensor 21 does not detect the capsule body 401, it indicates that the capsule body 401 and the capsule cap 402 are not separated. When the capsule body 401 and the capsule cap 402 are not separated, the ejection mechanism cooperates with the straw 24 to eject the empty capsule shell from the material hole 1011 and the accommodating hole 1031.

[0043] Further, in this embodiment, the ejection mechanism includes: a fifth driving member 22 and a third ejector pin 23, the fifth driving member 22 and the third ejector pin 23 are located below the material tray 101, the fifth driving member 22 drives the third ejector pin 23 to move upward, the third ejector pin 23 extends into the material hole 1011, and pushes the capsule body 401 upward, and the suction pipe 24 sucks the empty capsule shell by suction, and the two work together to push the empty capsule shell out of the accommodating hole 1031. Further, the suction pipe 24 is connected to the accommodating box 25, and the sucked empty capsule shell enters the accommodating box 25 for storage.

[0044] The third station of the automated preparation system is a filling station, which is provided with a filling device 30, such as Figure 5 As shown, the filling device 30 includes: a second bracket 31, a second funnel 32, a first motor 33 and a screw 34. The second funnel 32 is arranged on the second bracket 31, and capsule powder is arranged in the second funnel 32. The first motor 33 is arranged above the second funnel 32, and the first motor 33 is connected to the screw 34. One end of the screw 34 passes through the second funnel 32 and can extend into the capsule body 401. The first motor 33 is used to drive the screw 34 to rotate to stir the capsule powder, so as to make the capsule powder leak into the capsule body 401.

[0045] Specifically, after the empty capsule shell is separated, the push rod 102 contracts, driving the capsule cap 402 to leave the material hole 1011, and the material tray 101 rotates to the third station. The material hole 1011 is aligned with the discharge port of the second funnel 32. The second funnel 32 is filled with capsule powder. When the first motor 33 rotates, it can drive the screw 34 to rotate. The screw 34 passes through the discharge port of the second funnel 32 and extends into the capsule body 401. The screw 34 stirs the capsule powder so that the capsule powder leaks out of the second funnel 32 into the capsule body 401.

[0046] Furthermore, in the embodiment of the utility model, the filling device 30 further includes: a sixth driving member 35 and a partition 36. The sixth driving member 35 is connected to the second bracket 31, and is used to drive the partition 36 to move. The partition 36 is located above the material tray 101. When the amount of capsule powder in the capsule body 401 is filled appropriately, the sixth driving member 35 drives the partition 36 to move, and the partition 36 blocks the discharge port of the second funnel 32 to prevent the capsule powder in the second funnel 32 from leaking out.

[0047] After the capsule body 401 is filled with capsule powder, the material tray 101 rotates to the fourth station, which is a medicine drop processing station, and is provided with a medicine drop adding device 40. The medicine drop adding device 40 includes: a medicine bottle 41 and an injection needle 43. The medicine bottle 41 contains radioactive medicine liquid, and the injection needle 43 is connected to the medicine bottle 41. The injection needle 43 is used to inject the radioactive medicine liquid into the capsule body 401 filled with capsule powder.

[0048] Specifically, after the material hole 1011 rotates to the fourth position, the injection needle 43 draws the radioactive liquid medicine from the liquid medicine bottle 41 and injects the radioactive liquid medicine into the capsule body 401 .

[0049] Further, in this embodiment, the liquid medicine dripping device 40 also includes: a pump 42, a third bracket 44, a seventh driving member 45, a clamping block 46 and a cleaning bottle 47. The pump 42 is used to pump the radioactive liquid medicine in the liquid medicine bottle 41 into the injection needle 43. The seventh driving member 45 is arranged on the third bracket 44 and can slide along the third bracket 44. The seventh driving member 45 is connected to the clamping block 46 to drive the clamping block 46 to move. The clamping block 46 is used to clamp the injection needle 43. After the injection needle 43 injects the radioactive liquid medicine into the capsule body 401, the material hole 1011 rotates to the fifth station. The seventh driving member 45 slides along the third bracket 44 to align the injection needle 43 with the cleaning bottle 47. The seventh driving member 45 drives the injection needle 43 to extend into the cleaning bottle 47 for cleaning. Optionally, in this embodiment, the pump 42 can be a peristaltic pump or a syringe pump.

[0050] like Figure 5 As shown, the fifth station of the automated preparation system is a capsule closing station, which is provided with a capsule closing device 50, which includes a third driving member 51, a first ejector pin 52 and a cover plate 53. The third driving member 51 is located below the material tray 101, and the first ejector pin 52 is connected to the third driving member 51. Driven by the third driving member 51, the first ejector pin 52 can extend into the material hole 1011 to push the capsule body 401 and the capsule cap 402 to fit together.

[0051] Specifically, after the material hole 1011 rotates to the fifth position, the push rod 102 extends to push the accommodating block 103 to move, so that the accommodating hole 1031 is aligned with the material hole 1011 again. The third driving member 51 drives the first ejector pin 52 to move upward, and the first ejector pin 52 extends into the material hole 1011 to push the capsule body 401 to move upward, so that the capsule body 401 and the capsule cap 402 are fitted.

[0052] Furthermore, in the present embodiment, the push rod 102 is provided with a cover plate 53. When the capsule body 401 and the capsule cap 402 are fitted together, the cover plate 53 moves to above the accommodating hole 1031. When the first ejector pin 52 pushes the capsule body 401 to move upward, the cover plate 53 abuts against the capsule cap 402, thereby preventing the capsule cap 402 from moving upward, so that the capsule body 401 and the capsule cap 402 are fitted together.

[0053] After the capsule body 401 and the capsule cap 402 are fitted together to form a capsule, the material tray 101 rotates to the sixth station, which is a testing station and is provided with a testing device 60. The testing device 60 is used to test the appearance quality of the capsule.

[0054] like Figure 6 As shown, the detection device 60 includes: a sliding mechanism, a second motor 63, a second suction cup 64 and a detection mechanism. The second motor 63 is connected to the sliding mechanism, and the sliding mechanism can drive the second motor 63 to move in the horizontal and vertical directions. The second suction cup 64 is connected to the second motor 63, and the second suction cup 64 is used to suck the capsule after being put on. The detection mechanism is used to detect the appearance quality of the capsule.

[0055] Specifically, the sliding mechanism includes: a first slide 61 and a second slide 62. The second slide 62 can slide along the first slide 61 to drive the second suction cup 64 to move horizontally. The second slide 62 can also move longitudinally to drive the second suction cup 64 to move longitudinally, so as to move the second suction cup 64 to the position of the capsule. The second suction cup 64 sucks the capsule out of the accommodating hole 1031. After being sucked out, the second motor 63 drives the capsule to rotate so that the detection mechanism can detect the appearance quality of the capsule.

[0056] Furthermore, in this embodiment, the detection mechanism includes: a visual camera 65, a light source 66 and a background plate 67, the background plate 67 is arranged opposite to the visual camera 65, and the light source 66 provides illumination for the visual camera 65. The second slide 62 can drive the capsule to rise and fall so that the capsule is opposite to the visual camera 65. When the second motor 63 rotates, it drives the capsule to rotate. The visual camera 65 performs high-speed shooting and comparison on the rotating capsule, and judges the appearance quality of the capsule through the software algorithm to remove unqualified products.

[0057] At this point, the preparation of a single radioactive capsule is completed. While this radioactive capsule is being prepared, other workstations can simultaneously carry out the preparation operation of the next radioactive capsule.

[0058] Optionally, in this embodiment, the first slide 61 and the second slide 62 may be electric slides or pneumatic slides. It is understandable that in this embodiment, the first slide 61 and the second slide 62 are prior art, and those skilled in the art may configure them according to the relevant structures in the prior art, so they will not be described in detail.

[0059] Further, in the embodiment of the present utility model, the first driving member 14, the second driving member 71, the third driving member 51, the fourth driving member 16, the fifth driving member 22, the sixth driving member 35 and the seventh driving member 45 can be cylinders, electric cylinders or hydraulic cylinders.

[0060] like Figure 1 As shown, in an embodiment of the utility model, the automated preparation system further includes a control cabinet 200, on which a display screen 300 is disposed. The control cabinet 200 is a control system of the automated preparation system, and production operations or parameter settings can be performed through the display screen 300 to achieve automated preparation of radioactive capsules.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
