Description

[0002] At present, the existing activity detection mechanisms usually use the design of cylinders and guide rails to control the movement of vials, and are specifically designed for the detection of vials. Due to the limitations of this design, these mechanisms often occupy a large amount of space in terms of height, especially inside the hot cell. Such an arrangement will cause obstacles during the operation of the robotic arm, and special consideration needs to be given to avoiding the activity detection mechanism, and even the size of the hot cell may need to be adjusted. This design limitation not only affects the operation of the robotic arm, but also imposes certain limitations and impacts on the design and layout of the overall dispensing equipment; moreover, generally, a cylindrical activity detector is arranged at the lower side of the nuclear medicine detection equipment.

[0026] Please refer to Figure 1 , Figure 1 which is a three-dimensional structural schematic diagram of a chain-type activity detection mechanism provided by an embodiment of the present invention; this mechanism can be applied to the equipment for nuclear medicine dispensing, automatically perform lamp inspection on the filled syringes and vials, and can be embedded into the nuclear medicine dispensing equipment, and can automatically perform activity detection on the dispensed nuclear medicine liquid. Compared with the existing activity detection mechanism in terms of height, it can be greatly reduced, effectively improving the space utilization rate of the hot cell chamber, increasing the fault tolerance rate of the equipment, and reducing the design cost.

[0027] Please refer to Figure 1 , the above-mentioned chain-type activity detection mechanism includes: a guide rail mounting seat 1, a power source 9, a chain drive assembly, and a bracket 7. The chain drive assembly is connected to the bracket 7, and the chain drive assembly is connected to the power source 9; the power source 9 is connected to the guide rail mounting seat 1.

[0028] By adopting a chain drive assembly, compared with the traditional cylinder-guide rail system, the chain drive assembly can more flexibly adapt to containers of different sizes and shapes, such as vials and syringes. The chain drive can perform smooth movement in the vertical direction without a large amount of up and down space to accommodate the complex cylinder-guide rail structure.

[0029] Due to the more compact and direct movement mode of the chain drive assembly, the height of the overall activity detection mechanism can be effectively reduced. In this way, the space occupied inside the hot cell will be significantly reduced, reducing the need for the robotic arm to avoid or plan space during operation.

[0030] The compactness and efficiency of the mechanism design mean that the space inside the hot cell can be better utilized, not only reducing the occupation in height but also making the overall layout more flexible and easier for robotic arm operation. In addition, the simplified structure design usually means fewer failure points and maintenance costs, improving the fault tolerance and reliability of the equipment.

[0031] By adopting a chain drive assembly, the cost and assembly complexity of the complex cylinder-guide rail system can be avoided, thus reducing costs in the overall design stage.

[0032] In one embodiment, please refer to Figure 1 , the above-mentioned chain drive assembly includes a chain 8, a driving sprocket 6, a follower sprocket assembly 5 and a guide rail assembly. The guide rail assembly is connected to a bracket 7; the bracket 7 is connected to the chain 8; the chain 8 is respectively connected to the driving sprocket 6 and the follower sprocket assembly 5; the guide rail assembly is connected to the bracket 7, and the driving sprocket 6 is connected to a power source 9.

[0033] In one embodiment, please refer to Figure 1 , the above-mentioned guide rail assembly includes a linear guide rail 10 and a slider adapter block 2. The guide rail is connected to a guide rail mounting seat 1; the slider adapter block 2 is connected to the linear guide rail 10; the slider adapter block 2 is connected to the bracket 7.

[0034] In one embodiment, please refer to Figure 1 , the above-mentioned power source 9 includes a servo motor.

[0035] In one embodiment, please refer to Figure 1 , on one side of the bracket 7 away from the chain 8, it is recessed towards the direction close to the chain 8 to form a mounting groove.

[0036] In one embodiment, please refer to Figure 1 , the above-mentioned follower sprocket assembly 5 is connected to the linear guide rail 10.

[0037] The above mechanism, together with the robotic arm, implements the corresponding activity detection process. Specifically, the robotic arm clamps the vial or syringe from the area to be filled and transfers it to the bracket 7; the bracket 7 is driven by the chain 8 to control the rotation of the servo motor, and the syringe or vial is sent into the activity detector; the activity detection function is completed in the activity detector; after the detection is completed, the servo motor rotates in the reverse direction to raise the bracket 7 to the position waiting to be taken away, waiting for the operation of the robotic arm.

[0038] In this embodiment, the power source 9 is a servo motor, and the lifting movement of the bracket 7 is realized through the driving sprocket 6, the chain 8 and the follower sprocket assembly 5. The linear guide 10, the slider adapter block 2 and the bracket 7 constitute the basis of the movement trajectory to ensure smooth lifting movement.

[0039] In one embodiment, please refer to Figure 1 , the upper limit block 4 is connected to the above-mentioned guide rail mounting seat 1.

[0040] In one embodiment, please refer to Figure 1 , the lower limit block 3 is connected to the above-mentioned linear guide 10.

[0041] In one embodiment, please refer to Figure 1 , the above-mentioned linear guide 10 is a ball linear guide 10.

[0042] In this embodiment, the upper limit block 4 is provided on the guide rail mounting seat 1 and the lower limit block 3 on the linear guide 10 to ensure that the bracket 7 will not exceed the safe range during the lifting process, guaranteeing the operation safety; the linear guide 10 adopts a ball linear guide to provide high-precision motion control and low friction, ensuring the smoothness and accuracy of the lifting process of the bracket 7.

[0043] The design of the bracket 7 is recessed towards the direction of the chain 8 on one side of the chain 8 to form a mounting groove. This design can effectively reduce the space occupation, making the overall equipment more compact and efficient.

[0044] Using the ball linear guide and the compactly designed mounting groove of the bracket 7, the space occupation of the equipment in the hot cell is minimized, improving the space utilization rate.

[0045] The power transmission link is through the servo motor and the chain 8, so that the lifting movement of the bracket 7 can be accurately controlled within the required range, ensuring the accuracy of the activity detection process.

[0046] The linear guide 10 with the upper limit block 4 and the lower limit block 3 and the bracket structure with safety design ensure the safety and stability during the operation process and reduce the possibility of operation errors.

[0047] In summary, this design not only realizes the functions of nuclear medicine liquid dispensing and activity detection, but also improves the efficiency, accuracy and safety of the equipment through an optimized structure and power transmission system, making it suitable for pharmaceutical production environments that require high automation and precise control.

[0048] In one embodiment, as Figure 2 shown, a sensor assembly 11 is further connected to the above-mentioned guide rail mounting seat 1; the sensor assembly 11 is used to detect whether the bracket 7 reaches the upper limit position, etc. The sensor assembly 11 can monitor the position of the bracket 7 in real time, including whether it reaches the upper limit, so as to ensure that the bracket 7 can accurately stop at a predetermined position during the movement process, improving the accuracy and reliability of the system.

[0049] By detecting the position of the bracket 7, especially the upper limit position, the system can prevent the bracket 7 from exceeding the safe range, prevent equipment damage or operation errors, and improve the safety of the equipment.

[0050] The working process of the above-mentioned chain-type activity detection mechanism is as follows:

[0051] After the nuclear medicine liquid dispensing is completed, the robotic arm will pick up a syringe or a vial from the loading area and then place it on the bracket 7. Then, the robotic arm releases the gripper to fix the syringe or vial on the bracket 7. At this time, the servo motor starts to rotate, drives the chain 8 through the driving sprocket 6, and then drives the follower sprocket assembly 5 to rotate. The chain 8 is connected to the bracket 7. As the motor rotates, the bracket 7 starts to move downward to send the liquid medicine sample into the activity detector for activity detection. After the detection is completed, the servo motor rotates in the reverse direction to raise the bracket 7 and wait for the robotic arm to operate again to pick up the liquid medicine sample.

[0052] For the above-mentioned chain-type activity detection mechanism, by setting the guide rail mounting seat 1, the power source 9, the chain drive assembly and the bracket 7, the power source 9 is connected to the bracket 7 through the chain drive assembly and is connected to the guide rail mounting seat 1; it can be embedded into the nuclear medicine dispensing equipment, automatically perform activity detection on the dispensed nuclear medicine liquid, and can greatly reduce the height compared with the existing activity detection mechanism, effectively improving the utilization rate of the hot cell chamber space, increasing the equipment fault tolerance rate, and reducing the design cost.
