Description

Technical Field

[0001] This invention relates to the field of seed source sorting technology, specifically to a sealed automatic seed source sorting system and device. Background Technology

[0002] In the field of nuclear medicine, the precise sorting of sealed seed sources (such as iodine [125I] sealed seed sources) is a core element in ensuring the safety and effectiveness of radiotherapy. With increasing demands for diverse seed source specifications and higher sorting efficiency in clinical applications, the technological iteration of automated sorting equipment has become a focus of industry attention. In existing technologies, automated sealed seed source activity sorting systems often use hollow glass tubes as the feeding channel, combined with a feeding push rod and a feeding cylinder to achieve precise supply of single seed sources. Activity is then detected through an ionization chamber, and finally, a hollow pipette is used to dispense the seed sources into pre-set containers. This technical solution demonstrates good automation capabilities in single-specification seed source sorting scenarios.

[0003] However, the above-mentioned technical architecture has the following inherent limitations: the single-channel feeding system can only be adapted to a single specification of titanium tube, which means that the equipment needs to be stopped to replace components when facing the sorting needs of multiple specifications, directly causing production interruption; the feeding mechanism relies on mechanical cylinders for propulsion, and the sorting cycle is limited by the cylinder response speed. A single sorting generates two coordinated actions, the process and the return, which is difficult to meet the rapid sorting needs of high-activity seed sources. The mechanical action links are redundantly designed, which manifests as low equipment utilization, obvious bottlenecks in sorting efficiency, and high demand for manual intervention in application. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic sorting system for sealed seed sources, which is used for dynamic sorting and packaging of seed sources of various specifications, thereby improving efficiency and reducing the risk of human exposure to radiation.

[0005] To achieve the above objectives, the present invention provides a sealed seed source automatic sorting system, comprising: a dual-channel feeding module, a single-seed source separation feeding module, an activity detection module, and an automatic dispensing module. The dual-channel feeding module is used for synchronous vibration sorting and directional conveying of seed sources of two specifications. The single-seed source separation feeding module is used to receive the directionally conveyed seed sources of two specifications and control the alternating capture and airflow jet output of the seed sources of the two specifications through dynamic station switching via a switching plate. The activity detection module is used to receive the seed sources output by airflow jet and measure the activity of the seed sources through flow direction control of a Y-shaped inlet pipe and a retention mechanism in the detection tube. The automatic dispensing module is used to release the seed sources that have completed the activity measurement by inserting and mounting seed source collection bottles and injection conduits positioned in the target activity range by a rotating placement plate, thereby collecting the seed sources by graded activity.

[0006] Optionally, the synchronous vibration sorting and directional conveying of the dual-specification seed sources includes: controlling the vibration of the first seed source circular vibrating plate and the second seed source circular vibrating plate, using track guidance to sort the dual-specification seed sources in a single column; and using the first and second flat vibration conveying tracks, which are respectively connected to the first and second seed source circular vibrating plates, to convey the sorted seed sources to the corresponding feed bins.

[0007] Optionally, the step of receiving the dual-specification seed source delivered by the directional conveyor and controlling the alternating capture and airflow jet output of the dual-specification seed source through dynamic station switching of the switching plate includes: setting the initial position of the switching plate to a first station; when the first-specification seed source is detected to have landed in the first feeding chamber of the feeding hopper, sending a station switching signal to trigger the station switching; controlling the switching plate to rotate from the first station to a second station; the second feeding chamber of the feeding hopper captures the second-specification seed source, and controlling the first feeding chamber to rotate to the air blowing pipe position; when the second-specification seed source is detected to have landed in the second feeding chamber of the feeding hopper, controlling the switching plate to rotate back to the first station, the first feeding chamber captures the first-specification seed source, and controlling the second feeding chamber to rotate to the air blowing pipe position.

[0008] Optionally, the step of receiving the dual-specification seed source delivered by the directional conveyor and controlling the alternating capture of the dual-specification seed source and the air jet output of the seed source through the switching plate dynamic station switching further includes: when the first feeding chamber or the second feeding chamber is rotated to the position of the air blowing pipe, controlling the air pump to inject compressed air into the feeding chamber through the air blowing pipe, so that the seed source is pushed into the coaxial output air pipe by the air flow.

[0009] Optionally, the seed source receiving the air jet output is used to measure seed source activity through flow direction control of the Y-type inlet pipe and retention mechanism of the detection tube. This includes: after the seed source output by the air jet enters the Y-type inlet pipe through the flexible air tube, when a signal indicating that the seed source has arrived in the Y-type inlet pipe is detected, the seed source flow path is switched from the discharge channel to the detection channel; after the channel switching is completed, the seed source enters the detection mechanism through the detection channel, and the detection mechanism keeps the seed source centered and triggers the activity measurement; the detector in the detection mechanism performs the activity measurement on the centered seed source; after the activity measurement is completed, the seed source flow path is switched from the detection channel to the discharge channel.

[0010] Optionally, the step of collecting seed sources that have completed the seed source activity measurement by rotating the placement plate to position the seed source collection bottle and the injection conduit in the target activity range for graded collection includes: receiving the seed sources that have completed the seed source activity measurement; positioning the seed source collection bottle in the target activity range below the injection conduit by rotating the placement plate; controlling the injection conduit to release the seed source after inserting it into the seed source collection bottle; and performing a three-stage counting to complete the graded collection of seed source activity.

[0011] Optionally, the three-stage counting includes: after the seed source enters the injection conduit, controlling the obstruction to prevent the seed source from falling, detecting the seed source position signal, and initializing the counter; when the injection conduit is inserted into the seed source collection bottle, controlling the seed source obstruction to retract, and triggering the sensor to perform counting when the seed source falls through the detection zone; after the seed source passes through the detection zone, performing the same sensor counting result and expected value verification.

[0012] On the other hand, the present invention provides a sealed seed source automatic sorting device, including a sealed seed source automatic sorting system. The device includes: a housing, a control panel, and a label printer. The housing is provided with: a dual-channel feeding assembly, including a first seed source circular vibrating plate and a second seed source circular vibrating plate arranged side by side, and a first and a second horizontal vibrating conveyor rail respectively connected to each other; a single seed source separation feeding assembly, including a mounting frame with a fan-shaped cavity, and a switching plate sealed and rotatably arranged in the fan-shaped cavity. The mounting frame has a blowing pipe and an output air pipe coaxially arranged on both sides. Two openings are opened on one side of the blowing pipe, and the two openings are respectively located on both sides of the blowing pipe. A first feeding chamber and a second feeding chamber are opened on the switching plate; an activity detection assembly, including a detector, a Y-shaped inlet pipe, and a bracket and a detection tube coaxially arranged inside the detector; and an automatic dispensing assembly, including a rotating placement plate driven by a motor. The rotating placement plate has multiple placement slots distributed circumferentially on the rotating placement plate. Seed source collection bottles are placed in the placement slots. The assembly also includes a vertically arranged electric guide rail, and a sliding block on the electric guide rail is fixedly installed with an injection conduit.

[0013] Optionally, the outlet ends of the first and second vibrating conveyor tracks are respectively aligned with two openings; the output air pipe is connected to the inlet end of the Y-shaped inlet pipe through a flexible air pipe; and the outlet end of the Y-shaped inlet pipe is connected to the injection conduit through a flexible air pipe.

[0014] Optionally, the mounting bracket is equipped with an electric cylinder for driving the switching plate to deflect. Under the control of the electric cylinder, the switching plate has two positions: a first position where the first feeding chamber is aligned with the outlet of the first flat vibrating conveyor track, and the second feeding chamber is aligned with the air blowing pipe and the output air pipe; and a second position where the second feeding chamber is aligned with the outlet of the second flat vibrating conveyor track, and the first feeding chamber is aligned with the air blowing pipe and the output air pipe.

[0015] The aforementioned technical solution employs a dual-channel parallel feeding mechanism, enabling simultaneous processing and dynamic adaptation of seed sources of different specifications. This eliminates the waiting time associated with traditional sequential operations, significantly improving overall capacity. Simultaneously, the use of airflow jet transmission instead of mechanical propulsion ensures high efficiency and low failure rate in seed source transport, avoiding jamming issues. In terms of safety, the combination of a container design and automated dispensing process drastically reduces the frequency of operator contact with radiation sources, effectively ensuring a safe working environment. Furthermore, the integrated intelligent sorting and collection function, through precise activity detection and positioning release, ensures the accuracy and reliability of seed source dispensing, providing a stable and reliable sorting solution for the nuclear medicine field. Overall, this system not only optimizes sorting efficiency but also enhances radiation protection and ease of operation, addressing the challenges of processing multi-specification seed sources.

[0037] The following is in conjunction with the appendix Figure 1 - Appendix Figure 18 The specific implementation methods of the embodiments of the present invention will be described in detail below. It should be understood that the specific implementation methods described herein are only for illustrating and explaining the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0038] It should be noted that the acquisition, transmission, storage, use, and processing of data in the technical solution of this application all comply with the relevant provisions of national laws and regulations. In the embodiments of this application, certain existing industry solutions such as software, components, and models may be mentioned. These should be considered exemplary, intended only to illustrate the feasibility of implementing the technical solution of this application, and do not imply that the applicant has already used or necessarily used such solutions.

[0039] In the process of realizing this invention, the inventors of this application discovered that existing seed source sorting equipment only supports sorting of a single specification of seed source. Switching specifications requires stopping the machine to replace components, resulting in interruption of production capacity and loss of efficiency. The packaging process requires manual operation of the seed source collection bottle, and the operator is directly exposed to the radiation environment. In addition, manual sorting has a high probability of missing detection, which can easily lead to errors in activity grading.

[0040] Example 1

[0041] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a sealed seed source automatic sorting system, including: a dual-channel feeding module, a single-seed source separation feeding module, an activity detection module, and an automatic dispensing module. The dual-channel feeding module is used for synchronous vibration sorting and directional conveying of seed sources of two specifications; the single-seed source separation feeding module is used to receive the directionally conveyed seed sources of two specifications, and controls the alternating capture of seed sources of two specifications and the airflow jet-type output of seed sources through dynamic station switching of a switching plate; the activity detection module is used to receive the seed sources output by airflow jet, and performs seed source activity measurement through flow direction control of a Y-type inlet pipe and a detection tube retention mechanism; the automatic dispensing module is used to release the seed sources that have completed the seed source activity measurement by inserting and releasing seed source collection bottles and injection conduits positioned in the target activity range by a rotating placement plate, and to collect the seed sources by grade according to their activity.

[0042] In a preferred embodiment of the present invention, the synchronous vibration sorting and directional conveying of dual-specification seed sources includes: controlling the vibration of the first seed source circular vibrating disk and the second seed source circular vibrating disk, using track guidance to sort the dual-specification seed sources in a single column; and using the first and second flat vibration conveying tracks respectively connected to the first and second seed source circular vibrating disks to convey the sorted seed sources to the corresponding feed bins.

[0043] Specifically, the entire system process is centrally controlled by the PLC program on the control panel. During the system startup phase, initialization configuration is performed first. This initialization configuration includes setting task parameters and equipment self-checks. The task parameters set include the current operator's name, product name, batch number, specifications, grading range, number of gradings, and quantity per bottle, and these settings are saved. Equipment self-checks include verifying the empty status of the rotating tray, detecting air pump pressure, and calibrating various sensors. If two specifications of seed material are fed and tested simultaneously, two grading ranges are set to correspond to different specifications.

[0044] Furthermore, the first and second seed source vibrating discs process seed sources of different specifications respectively. Sealed seed sources of the first (0.6mm) and second (0.8mm) specifications are fed into the first and second seed source vibrating discs respectively. This achieves synchronous feeding and sorting of seed sources of different specifications. In actual use, if sorting of different specifications of seed sources is not required, seed sources of the same specification can be fed into both the first and second seed source vibrating discs to improve subsequent sorting efficiency. The vibration motors of the first and second seed source vibrating discs are started via the control panel, causing the seed sources to be sorted in a single row within the guide grooves on the disc surface. The sorted seed sources automatically slide into the corresponding flat vibration track.

[0045] Preferably, the first flat vibrating conveyor track conveys a seed source of the first specification (0.6mm), and the second flat vibrating conveyor track conveys a seed source of the second specification (0.8mm). The first seed source circular vibrating disk corresponds to the first flat vibrating conveyor track, and the second seed source circular vibrating disk corresponds to the second flat vibrating conveyor track. The vibration frequencies of the first flat vibrating conveyor track and the second flat vibrating conveyor track are both constant values.

[0046] Preferably, the dual-channel feeding module achieves synchronous vibration sorting and conveying of seed sources of different specifications through the independent parallel operation of dual circular vibrating discs and flat vibrating tracks. This can eliminate the downtime of traditional equipment specification switching, significantly improve overall production capacity, and solve the problem of material jamming caused by friction differences by dynamically adjusting vibration parameters to adapt to the physical characteristics of seed sources. The precision track design ensures the stability of conveying.

[0047] In a preferred embodiment of the present invention, receiving directionally conveyed dual-specification seed sources and controlling the alternating capture of the dual-specification seed sources and the airflow jet output of the seed sources through dynamic station switching via a switching plate includes:

[0048] S110: Set the initial position of the switching plate to the first station. When the first specification seed source is detected to be in the first feeding chamber of the feeding hopper, a station switching signal is sent to trigger the station switching.

[0049] Specifically, the switching plate is equipped with a first feeding chamber and a second feeding chamber. The initial position of the switching plate is set at the first station, where the first feeding chamber is aligned with the first vibrating conveyor track (receiving 0.6mm seed sources), and the second feeding chamber is aligned with the air blowing pipe and the air conveying pipe. The first specification (0.6mm) seed sources on the first vibrating conveyor track are conveyed into the first feeding chamber. When the photoelectric sensor in the first feeding chamber detects that the first specification (0.6mm) seed sources have been positioned, the system sends a switching signal to the switching plate.

[0050] S120: Control the switching plate to rotate from the first station to the second station.

[0051] Specifically, after the switching board control component receives the switching signal sent by the system, it drives the switching board to rotate to the second station. The second station is where the second feeding chamber is aligned with the outlet of the second vibrating conveyor track, and the first feeding chamber is aligned with the air blowing pipe and the air conveying pipe.

[0052] Preferably, the switching board control assembly may include an electric cylinder, a drive rack, and a pull gear.

[0053] S130: The second feeding chamber of the feeding hopper captures the second-specification seed source and controls the first feeding chamber to rotate to the position of the air blowing pipe.

[0054] Specifically, after the switching plate rotates to the second position, 0.8mm seed material is fed into the second feeding chamber. When the 0.8mm seed material enters the second feeding chamber, a feedback signal is sent after the photoelectric sensor detects the seed material's placement. The first feeding chamber (which already contains the previously entered 0.6mm seed material) then rotates to the air blowing pipe position. The control panel starts the air pump, and compressed air is injected to transport the 0.6mm seed material to the activity detection component via the air delivery pipe.

[0055] S140: When the second specification seed source is detected to be in the second feeding chamber of the feeding hopper, the control switch plate is turned back to the first position, the first feeding chamber captures the first specification seed source, and the control switch is turned to the air blowing pipe position.

[0056] Specifically, after the second-specification seed source is positioned and the photoelectric sensor completes its detection, the system sends a switching signal to the switching board. The switching board control component drives the switching board to reverse, returning it to the first station. At this point, the first feeding chamber aligns with the first vibrating conveyor track, and the new 0.6mm seed source enters the first feeding chamber. The second feeding chamber moves to the position of the air blowing pipe. The control panel starts the air pump, injecting compressed air to transport the second-specification (0.8mm) seed source to the activity detection component via the air delivery pipe. If the station switching is successful, the "Equipment Abnormality" section on the control panel remains gray (no alarm content displayed). If the switching fails (e.g., the seed source does not enter the first or second feeding chamber), the "Equipment Abnormality" section on the control panel displays an alarm log.

[0057] Preferably, the alarm log may include the time when the anomaly was detected, the alarm content, and the alarm code.

[0058] Preferably, the single-seed source separation feeding module achieves parallel processing of dual-specification seed source feeding and airflow jet output through a dynamic station switching mechanism of the switching plate. Photoelectric sensors monitor the seed source placement status within the feeding chamber in real time, generating feedback signals to drive the control unit and trigger the rotating mechanism to precisely switch stations. Once the first-specification seed source enters the feeding chamber and is confirmed to be in place, the rotating mechanism immediately rotates the switching plate to the second station, aligning the second feeding chamber with the corresponding track inlet. Simultaneously, the first feeding chamber moves to the air blowing pipe position. The pneumatic jetting device is activated synchronously during the station switching process, rapidly outputting the positioned seed source through the air delivery pipe. This design, through the coordination of photoelectric sensor closed-loop control and mechanical action, ensures continuous processing of dual-specification seed sources under physically isolated conditions, significantly reducing equipment idle time. Furthermore, the pneumatic jetting replaces the traditional mechanical push rod structure, significantly shortening the transmission time of a single seed source and ensuring the efficiency and purity of the sorting process.

[0059] In a preferred embodiment of the present invention, seed sources receiving air jet output are used to measure seed source activity through flow direction control of the Y-type inlet pipe and retention mechanism of the detection tube. This includes: after the air jet output seed sources enter the Y-type inlet pipe through the flexible air tube, when a signal indicating that the seed sources have arrived in the Y-type inlet pipe is detected, the seed source flow path is switched from the discharge channel to the detection channel; after the channel switching is completed, the seed sources enter the detection mechanism through the detection channel, and the detection mechanism keeps the seed sources centered and triggers the activity measurement; the detector in the detection mechanism performs the activity measurement on the centered seed sources; after the activity measurement is completed, the seed source flow path is switched from the detection channel to the discharge channel.

[0060] Specifically, the seed source, delivered via an air jet, enters the side pipe of the Y-shaped inlet connector through the air supply pipe. It is blocked by a movable baffle. After a photoelectric sensor inside the side pipe detects the seed source's arrival, it sends a signal to the control panel. Upon receiving this signal, the control panel displays "Detecting" in the status bar and energizes the electromagnet. The movable baffle switches from the discharge state to the detection state. At this time, the outlet end of the Y-shaped inlet connector is blocked, while the inlet end and feed end of the Y-shaped inlet connector are opened, connecting them. The seed source enters the detection tube inside the detector for radioactivity detection. The detector is a radioactivity meter, and the size of the detection tube is designed to allow individual seed sources to enter vertically while preventing them from tipping over. The diameter of the constricted orifice at the bottom of the detection tube is smaller than that of all seed source sizes, such as less than 0.6mm, so that 0.6mm and 0.8mm seed sources can be detected at the constricted orifice.

[0061] Furthermore, after the seed source testing is completed, the control panel de-energizes the electromagnet, and the movable baffle switches from the testing state to the discharge state. In the discharge state, the inlet end of the Y-type inlet pipe is blocked, while the inlet end and outlet end of the Y-type inlet pipe are connected. Simultaneously, an external air pump connected to the backflush airflow pipe blows out a reverse airflow. The backflush air pressure for 0.6mm seed sources is set to the base value, and the backflush air pressure for 0.8mm seed sources is set to the base value × 1.3. The tested seed sources are then discharged from the outlet end of the Y-type inlet pipe and conveyed to the automatic dispensing assembly.

[0062] Preferably, the constricted-hole airflow suspension design of the activity detection module ensures that the seed source is centered and non-contact for detection, avoiding deviations in activity values ​​caused by mechanical interference. The movable baffle allows for rapid switching, supporting an efficient detection cycle. The same detection tube is compatible with two types of seed sources, and the adaptive adjustment of backflush air pressure significantly reduces the risk of jamming, achieving non-destructive and high-precision activity measurement.

[0063] In a preferred embodiment of the present invention, the seed source whose activity has been measured is released by rotating the placement plate to position the seed source collection bottle and the injection conduit in the target activity range, and the seed source activity is collected in stages. This includes: receiving the seed source whose activity has been measured; positioning the seed source collection bottle in the target activity range below the injection conduit by rotating the placement plate; controlling the injection conduit to be inserted into the seed source collection bottle and releasing the seed source, and performing a three-stage counting to complete the staged collection of seed source activity.

[0064] Furthermore, after the seed source enters the injection conduit, the control block prevents the seed source from falling, detects the seed source position signal, and initializes the counter; when the injection conduit is inserted into the seed source collection bottle, the control block retracts, and when the seed source falls through the detection zone, the sensor is triggered to perform counting; after the seed source passes through the detection zone, the same sensor counting result and expected value are verified.

[0065] Specifically, after the activity detection component completes the activity detection of the current seed source, the detected seed source is divided into grades and then packaged. The PLC obtains the activity value of the current seed source and the corresponding grade range. If two specifications of seed source materials are fed and tested at the same time, two grades should be set, each corresponding to a different specification of seed source.

[0066] Preferably, the grading is set starting from an activity value of 400 microcells, with grading intervals of 50 microcells and a maximum value of 1400 microcells, forming multiple grading zones of 401-450 microcells, 451-500 microcells, 501-550 microcells...1351-1400 microcells.

[0067] Furthermore, the PLC matches the target grading based on the current seed source activity value. The target bottle number is updated synchronously on the control panel, and the rotating tray, on which the seed source collection bottles are placed, is driven to rotate.

[0068] Preferably, the number of seed source collection bottles corresponds to the number of graded zones. Typically, four additional special seed source collection bottles are set up to collect seed sources exceeding the lower limit or the upper limit, calibration titanium tubes for standard activity recovery and calibration, and seed sources with no activity. After the radioactivity meter receives a signal, it monitors the change in the activity value of the seed source. If the change in the activity value of the seed source is less than a set threshold (e.g., the activity value fluctuation is less than 1%), the seed source is determined to be a seed source with no activity after a delay and the countdown ends. The seed source is then placed in the seed source with no activity bottle.

[0069] Furthermore, the target seed source collection bottle is aligned with the injection conduit. Subsequently, the seed source enters the injection conduit through the discharge channel of the detection component. At this point, the retractable stop block immediately extends to block the seed source from falling. After the photoelectric sensor above the retractable stop block confirms that the seed source is in place, it sends a signal to the PLC, and the PLC initializes the counter.

[0070] Furthermore, the injection conduit is inserted into the mouth of the target seed collection bottle. After insertion, the retractable stop retracts, the seed falls, and the photoelectric sensor below the retractable stop triggers a counter when the seed passes through the detection zone. The count below the corresponding segment is updated. After the seed passes through the detection zone, the same photoelectric sensor performs a count verification. If the photoelectric sensor signal is "on → off → on", it is determined that a single seed has passed (count is valid); if the photoelectric sensor signal is continuously (e.g., >1 second) "off", it is determined that the conduit is empty (count is invalid). The PLC compares the photoelectric sensor count result (actual value) with the expected value (expected to count 1 seed). If they match, the segment count is incremented by 1 and updated to the segment count displayed on the control panel interface; if they do not match, an alarm is triggered, and the control panel displays the alarm log.

[0071] Preferably, when the number of a single bottle reaches a preset value (e.g., 100 seeds), the "No Full Bottle Dispensing" status on the control panel changes, for example, from green to red. The rotating tray is moved to the dispensing station, where the operator picks up the seed source collection bottle, labels it, and replaces it with a new seed source collection bottle.

[0072] Preferably, the automatic dispensing module automatically positions the target seed source collection bottle according to the seed source activity value by rotating the storage tray. The three-stage counting mechanism achieves a low dispensing error rate through closed-loop control of hindrance, fall detection and value verification. Moreover, the sealed dispensing reduces the risk of radioactive leakage to below the safety threshold and ensures that the dispensing process is accurate and reliable.

[0074] Reference Figures 3-18The second embodiment of the present invention provides a sealed seed source automatic sorting device, including: a sealed seed source automatic sorting device, including a box 1, a control panel 2 and a label printer 3, wherein the control panel 2 integrates a capacitive touch panel and a PLC programmable controller.

[0075] Please see Figure 3 - Figure 4 The housing 1 is equipped with a dual-channel feeding assembly 10, a single-seed source separation feeding assembly 20, an activity detection assembly 30, and an automatic dispensing and packaging assembly 40. The dual-channel feeding assembly 10, the single-seed source separation feeding assembly 20, the activity detection assembly 30, the automatic dispensing and packaging assembly 40, the label printer 3, and the photoelectric sensors installed on each component are all electrically connected to the control panel 2 to form a communication. The control panel 2 centrally controls the dual-channel feeding assembly 10, the single-seed source separation feeding assembly 20, the activity detection assembly 30, and the automatic dispensing and packaging assembly 40 to realize operations such as feeding, dispensing, detection, packaging, and labeling, and complete the automatic sorting of sealed seed sources.

[0076] Please see Figure 4 - Figure 6 The dual-channel feeding assembly 10 includes a first seed source circular vibratory plate 101 and a second seed source circular vibratory plate 102 arranged side by side, and a first flat vibratory conveyor track 103 and a second flat vibratory conveyor track 104 respectively connected to them. Sealed seed sources of 0.6mm and 0.8mm titanium tubes are respectively fed into the first seed source circular vibratory plate 101 and the second seed source circular vibratory plate 102, achieving synchronous feeding and sorting of seed sources of different specifications. In actual use, if it is not necessary to sort seed sources of different specifications, the same type of seed source can be fed into both the first seed source circular vibratory plate 101 and the second seed source circular vibratory plate 102. To improve the efficiency of subsequent sorting, a single-specification seed source is used. The first seed source circular vibrating plate 101 and the second seed source circular vibrating plate 102 arrange the seed sources in an orderly manner and transport them to the corresponding flat vibrating conveyor track through vibration. Compared with the traditional single-channel feeding method, the dual-channel feeding greatly improves the feeding efficiency and can process two batches of seed sources at the same time, reducing the overall sorting time. The first flat vibrating conveyor track 103 and the second flat vibrating conveyor track 104 use the principle of flat vibration to make the seed sources move forward smoothly and at a uniform speed on the track, ensuring that the seed sources can enter the subsequent components accurately.

[0077] Please see Figure 6 - Figure 10The single seed source separation feeding assembly 20 includes a mounting frame 201 with a fan-shaped cavity and a switching plate 202 that is rotatably and sealed within the fan-shaped cavity. The mounting frame 201 is perpendicular to the conveying direction of the first flat vibration conveying track 103 and the second flat vibration conveying track 104 in a plane and is located at the conveying end of the first flat vibration conveying track 103 and the second flat vibration conveying track 104. The first flat vibration conveying track 103 and the second flat vibration conveying track 104 are fitted with the side wall of the mounting frame 201 with a clearance to prevent the seed source from falling off. The specific clearance is set to 1 to 2 mm.

[0078] The mounting bracket 201 has an air blowing pipe 203 and an air output pipe 204 coaxially arranged on both sides. The air blowing pipe 203 is connected to an external air pump (not shown in the figure). Two openings are opened on one side of the air blowing pipe 203, respectively on both sides of the air blowing pipe 203. A first feeding chamber 205 and a second feeding chamber 206 are opened on the switching plate 202. The first feeding chamber 205, the second feeding chamber 206, and the two openings are all located on an arc trajectory with the rotation axis of the switching plate 202 as the center. The first feeding chamber 205... The distance between the first and second feeding chambers 205 and 206 on the arc trajectory is half the distance between the two openings on the arc trajectory. The outlet ends of the first and second vibrating conveying tracks 103 and 104 are respectively aligned with the two openings. By rotating the switching plate 202, the positions of the first feeding chamber 205 and 206 are changed, so that the first feeding chamber 205 and 206 alternately overlap with the outlet ends of the first and second vibrating conveying tracks 103 and 104 for feeding.

[0079] Please see Figure 4 - Figure 10 The switching plate 202 is fan-shaped and rotates coaxially with the fan-shaped cavity to ensure that the switching plate 202 can rotate normally within the fan-shaped cavity. The included angle of the switching plate 202 is smaller than that of the fan-shaped cavity. The rotation angle of the switching plate 202 is limited by the included angle of the fan-shaped cavity. The axial projection positions of the air blowing pipe 203 and the output air pipe 204 are located on the moving paths of the first feeding chamber 205 and the second feeding chamber 206. Therefore, when the switching plate 202 rotates, the first feeding chamber 205 can be coaxially aligned with the outlet end of the first flat vibration conveying track 103, and can also be coaxially aligned with the air blowing pipe 203 and the output air pipe 204. The second feeding chamber 206 can be coaxially aligned with the outlet end of the second flat vibration conveying track 104, and can also be coaxially aligned with the air blowing pipe 203 and the output air pipe 204.

[0080] Specifically, the mounting bracket 201 is equipped with an electric cylinder 207 for driving the switching plate 202 to deflect. Under the control of the electric cylinder 207, the switching plate 202 has two working positions:

[0081] First station: The first feeding chamber 205 is aligned with the outlet of the first flat vibrating conveyor track 103, and the second feeding chamber 206 is aligned with the air blowing pipe 203 and the output air pipe 204. At this time, the seed source on the first flat vibrating conveyor track 103 can enter the first feeding chamber 205, while the second feeding chamber 206 is in the air blowing and output state, blowing the previously entered seed source into the output air pipe 204 and sending it into the activity detection component 30 for activity detection.

[0082] Second station: The second feeding chamber 206 is aligned with the outlet of the second vibrating conveyor track 104, and the first feeding chamber 205 is aligned with the air blowing pipe 203 and the output air pipe 204. At this time, the seed source on the second vibrating conveyor track 104 can enter the second feeding chamber 206, while the first feeding chamber 205 is in the air blowing and output state, blowing the previously entered seed source into the output air pipe 204 and sending it into the activity detection component 30 for activity detection.

[0083] The electric cylinder 207 drives the switching plate 202 to switch between two workstations. The switching plate 202 achieves one feeding and one discharge during both the forward and return strokes, realizing the alternating separation and feeding of dual-channel seed sources, which further improves work efficiency. Compared with the traditional single-station feeding method, this dual-station design makes full use of time, reduces equipment idle time, and makes the entire sorting process smoother.

[0084] A rotating shaft is installed at the center of the switching plate 202, and a drive gear 2021 is fixedly installed on the rotating shaft. A drive rack 2071 is fixedly installed at the extension end of the electric cylinder 207. The drive gear 2021 meshes with the drive rack 2071. When the electric cylinder 207 extends or retracts, the drive rack 2071 drives the drive gear 2021 to rotate, thereby causing the switching plate 202 to rotate around the rotating shaft. The gear and rack transmission method has the characteristics of smooth transmission and high precision, which can accurately control the rotation angle and position of the switching plate 202, ensuring that the switching plate 202 accurately switches between two workstations.

[0085] It should be noted that when the switching plate 202 is in the first and second working positions, the side of the switching plate 202 abuts against the side of the fan-shaped cavity. The fan-shaped cavity limits the deflection angle of the switching plate 202, thereby achieving accurate switching between the two working positions and ensuring precise alignment of the first feeding cavity 205 and the first flat vibrating conveying track 103, as well as the second feeding cavity 206 and the second flat vibrating conveying track 104.

[0086] Both the first feeding chamber 205 and the second feeding chamber 206 are equipped with photoelectric sensors that are communicatively connected to the control panel 2. These sensors are used to trigger the switching between the first and second working positions. When the seed source enters the first feeding chamber 205 or the second feeding chamber 206, the photoelectric sensor detects that the seed source is in place and transmits a signal to the control panel 2. The control panel 2 controls the electric cylinder 207 to operate according to a preset program, thereby switching the working position of the switching plate 202. This automatic triggering method improves the automation level of the equipment, reduces manual intervention, and makes the sorting process more intelligent and efficient.

[0087] Specifically, the switching plate 202 is initially located at the first station. The first feeding chamber 205 is aligned with the outlet of the first flat vibrating conveyor track 103. 0.6mm seed material is fed into the first feeding chamber 205. The second feeding chamber 206 (which already contains the previously entered 0.8mm seed material) is aligned with the air blowing pipe 203 and the output air pipe 204. The air blowing pipe 203 blows air, blowing the previously entered 0.8mm seed material into the output air pipe 204 and sending it into the activity detection component 30 for activity detection. The switching between the first station and the second station is triggered when the photoelectric sensor in the first feeding chamber 205 detects that the 0.6mm seed material has been placed.

[0088] The switching plate 202 switches from the first station to the second station. The second feeding chamber 206 is aligned with the outlet of the second flat vibrating conveyor track 104. 0.8mm seed material is fed into the second feeding chamber 206. The first feeding chamber 205 (which already contains the previously entered 0.6mm seed material) is aligned with the air blowing pipe 203 and the output air pipe 204. The air blowing pipe 203 blows air, blowing the previously entered 0.6mm seed material into the output air pipe 204 and sending it into the activity detection component 30 for activity detection. The switching between the first station and the second station is triggered when the photoelectric sensor in the second feeding chamber 206 detects that the 0.8mm seed material has been placed.

[0089] Please see Figure 4 , Figure 11 - Figure 15 The activity detection component 30 includes a detector 301, a Y-type inlet pipe 302, and a bracket 303 and a detection tube 304 coaxially arranged inside the detector 301. The output air pipe 204 is connected to the inlet end of the Y-type inlet pipe 302 through a flexible air pipe. The single seed source transported from the output air pipe 204 enters the Y-type inlet pipe 302 and is transported into the detector 301 through the Y-type inlet pipe 302. After detection, it is transported into the automatic dispensing component 40 through the Y-type inlet pipe 302 for dispensing.

[0090] The Y-type inlet pipe 302 includes a vertical pipe 3021 and a side pipe 3022 installed at an angle. The top of the vertical pipe 3021 serves as the outlet end of the Y-type inlet pipe 302 and is connected to the injection conduit 404. The bottom of the vertical pipe 3021 serves as the inlet end of the Y-type inlet pipe 302 and is connected to the inlet of the detector 301. The open end of the side pipe 3022 serves as the inlet end of the Y-type inlet pipe 302 and is connected to the output air pipe 204.

[0091] The detector 301 is a radioactivity meter with an opening at the top. The bracket 303 is installed at the opening, and the detection tube 304 is inserted into the bracket 303 to form the feed port of the detector 301. The detection tube 304 is a hollow glass tube, which stays in the detection tube 304 during seed source detection.

[0092] The bottom end of the detection tube 304 has a constriction hole 3041. The inner diameter of the detection tube 304 is adapted to a single seed source, and the inner diameter is set to 0.9-1.0 mm, allowing a single seed source to enter vertically while preventing the seed source from tipping over. The diameter of the constriction hole 3041 is less than 0.6 mm, so the seed source can stay at the position of the constriction hole 3041. A backflush airflow pipe 305 is connected to the bottom end of the detection tube 304. The backflush airflow pipe 305 is connected to an external air pump. After the test is completed, the backflush airflow pipe 305 blows out a reverse airflow, so that the tested seed source is discharged from the detector 301 under the action of the airflow.

[0093] A movable shaft 306 is rotatably installed at the small included angle at the connection between the vertical pipe 3021 and the side pipe 3022. A movable baffle 307 is fixedly installed on the movable shaft 306. When the movable shaft 306 rotates, it will drive the movable baffle 307 to rotate synchronously, thereby switching the position of the movable baffle 307. When the movable baffle 307 deflects upward, it will block the outlet end of the Y-type inlet pipe 302. When the movable baffle 307 deflects downward, it will block the inlet end of the Y-type inlet pipe 302.

[0094] The Y-type inlet pipe 302 is equipped with a torsion spring and an electromagnet (not shown in the figure) for controlling the rotation of the movable shaft 306. The movable baffle 307 is deflected by the electromagnet and the torsion spring. Under normal conditions, the elastic force of the torsion spring drives the movable baffle 307 to deflect downward. After the electromagnet is energized, it generates a magnetic force to attract the iron piece located on the movable baffle 307, causing the movable baffle 307 to deflect upward. This allows the movable baffle 307 in the Y-type inlet pipe 302 to be in two states.

[0095] Detection status: The outlet end of the Y-type inlet pipe 302 is blocked, while the inlet end of the Y-type inlet pipe 302 is open and connected to the feed end of the Y-type inlet pipe 302.

[0096] Discharge status: The inlet end of the Y-type inlet pipe 302 is blocked, and the feed end of the Y-type inlet pipe 302 and the outlet end of the Y-type inlet pipe 302 are connected.

[0097] The switching between detection and discharge states is achieved by deflecting the movable baffle 307. A photoelectric sensor connected to the control panel 2 is installed at the side tube 3022 for switching between detection and discharge states. When the seed source enters the side tube 3022, the photoelectric sensor detects that the seed source is in place and transmits a signal to the control panel 2. The control panel 2 controls the electromagnet to move according to the preset program, thereby deflecting the movable baffle 307 and switching between detection and discharge states. This improves the automation level of the equipment, reduces manual operation, and makes the sorting process more intelligent and efficient.

[0098] Specifically, firstly, the movable baffle 307 inside the Y-type inlet pipe 302 is in the discharge state, blocking the inlet end of the Y-type inlet pipe 302. Single-grain seed sources from the output air pipe 204 enter the side pipe 3022 of the Y-type inlet pipe 302 and are blocked by the movable baffle 307. After the photoelectric sensor detects the material's arrival, the electromagnet is energized, and the movable baffle 307 switches from the discharge state to the detection state. At this time, the inlet end and the feed end of the Y-type inlet pipe 302 are connected, and the seed source... The feed material enters the detection tube 304 inside the detector 301 through the feed end of the Y-type inlet pipe 302 for radioactivity detection. After the detection is completed, the electromagnet is de-energized, and the movable baffle 307 switches from the detection state to the discharge state, blocking the inlet end of the Y-type inlet pipe 302 to prevent the seed source from being accidentally discharged from the inlet end. The feed end of the Y-type inlet pipe 302 is opened to connect with the outlet end of the Y-type inlet pipe 302. The seed source is discharged from the outlet end of the Y-type inlet pipe 302 by the back-blowing airflow and finally enters the automatic discharge and packaging component 40 for packaging.

[0099] After testing, the seed sources are categorized and packaged according to their test values. In this embodiment, the categorization starts from an activity value of 400 μC, with a categorization range of 50 μC and a maximum value of 1400 μC, forming multiple categorization zones such as 401-450 μC, 451-500 μC, 501-550 μC, ... 1351-1400 μC. It should be noted that if seed source materials of two specifications are fed and tested at the same time, the categorization range should be set in two parts, corresponding to the different specifications of seed sources.

[0100] Please see Figure 4 , Figure 16 - Figure 18The automatic dispensing component 40 includes a rotating tray 401 driven by a motor. Multiple placement slots 405 are distributed around the circumference of the rotating tray 401. Seed source collection bottles 402 are placed in the placement slots 405. The number of seed source collection bottles 402 corresponds to the number of grading zones. Usually, four special seed source collection bottles 402 are set up to collect seed sources below the lower limit and above the upper limit, calibration titanium tubes for standard activity recovery and calibration, and inactive seed sources. Inactive seed sources give a feeding signal to the control panel 2. After the radioactivity meter receives the signal, it monitors the change in the activity value of the seed source. If the change in the activity value of the seed source is less than the set threshold (e.g., the activity value fluctuation is less than 1%), the seed source is determined to be an inactive seed source after a delay and the countdown ends. The seed source is then placed into the inactive bottle.

[0101] It also includes a vertically set electric guide rail 403, on which a slider 406 is fixedly installed with a material inlet conduit 404. The outlet end of the Y-shaped inlet pipe 302 is connected to the material inlet conduit 404 through a flexible air tube. The electric guide rail 403 controls the raising and lowering of the material inlet conduit 404. During material discharge, the material inlet conduit 404 can be controlled to be inserted into the seed source collection bottle 402 to ensure that the seed source falls stably into the seed source collection bottle 402. After the seed source is tested, according to its test reading, the rotating placement plate 401 is driven by a motor to rotate, so that the seed source collection bottle 402 of the corresponding grade zone moves to below the material inlet conduit 404. For example, if the activity is detected as 920 Bq, the seed source collection bottle 402 corresponding to 901-950 Bq will rotate to below the material inlet conduit 404 to prepare for receiving the material.

[0102] The inlet conduit 404 is equipped with a retractable stop 407, which is driven by a miniature cylinder 408 mounted on the slider 406. The retractable stop 407 is used to block the seed source until the inlet conduit 404 is inserted into the seed source collection bottle 402. When the inlet conduit 404 has not yet been inserted into the seed source collection bottle 402, the miniature cylinder 408 drives the retractable stop 407 to extend, blocking the seed source from falling and preventing the seed source from falling out of the inlet conduit 404. When the inlet conduit 404 is inserted into the seed source collection bottle 402, the miniature cylinder 408 drives the retractable stop 407 to retract, and the seed source falls smoothly into the seed source collection bottle 402, avoiding the dropping and waste of the seed source during the dispensing process and improving the accuracy and reliability of dispensing.

[0103] Furthermore, a photoelectric sensor for detecting the dropping of seed source is installed above the retractable stop 407. When the seed source enters the injection conduit 404 and blocks the photoelectric sensor, the photoelectric sensor transmits the signal of the seed source's arrival to the control panel 2. The control panel 2 can monitor the dropping of seed source in real time to ensure the normal operation of the dispensing process.

[0104] The photoelectric sensor installed above the retractable stop 407 can count the number of collected seeds. When the seed collection bottle 402 reaches the specified number, the motor drives the rotating tray 401 to rotate, so that the full seed collection bottle 402 is rotated to a position that is easy for the operator to pick up and put down. At the same time, the label printer 3 prints out the label to complete the labeling and sorting.

[0105] Working principle: After the device is started, the control panel 2 initializes the dual-channel feeding assembly 10, the single seed source separation feeding assembly 20, the activity detection assembly 30, and the automatic dispensing assembly 40. In the dual-channel feeding assembly 10, the first seed source circular vibrating disk 101 and the second seed source circular vibrating disk 102 start to vibrate. If it is necessary to sort different specifications of seed sources, sealed seed sources of 0.6mm and 0.8mm titanium tubes are put in respectively. If it is not necessary to sort, the same specification of seed source can be put in to improve efficiency. They arrange the seed sources in an orderly manner through vibration and transport them to the corresponding first flat vibration conveying track 103 and second flat vibration conveying track 104. The first flat vibration conveying track 103 and the second flat vibration conveying track 104 use the principle of flat vibration to make the seed sources move forward smoothly and at a uniform speed.

[0106] Initially, the switching plate 202 of the single seed source separation feeding assembly 20 is in the first position. At this time, the first feeding chamber 205 is aligned with the outlet of the first flat vibration conveying track 103, and the second feeding chamber 206 is aligned with the air blowing pipe 203 and the output air pipe 204. The 0.6mm seed source on the first flat vibration conveying track 103 is fed into the first feeding chamber 205. When the photoelectric sensor at the first feeding chamber 205 detects that the 0.6mm seed source has fallen into place, it transmits the signal to the control panel 2. The control panel 2 controls the electric cylinder 207 to move according to the preset program. The drive rack 2071 fixed at the extension end of the electric cylinder 207 drives the drive gear 2021 fixed on the rotating shaft to rotate, so that the switching plate 202 rotates around the rotating shaft to switch to the second position.

[0107] During the switching process of the switching plate 202 to the second station, the second feeding chamber 206 is aligned with the outlet of the second flat vibrating conveyor track 104, and 0.8mm seed source is conveyed into the second feeding chamber 206. At the same time, the first feeding chamber 205 (which already contains the previously entered 0.6mm seed source) is aligned with the air blowing pipe 203 and the output air pipe 204. The air blowing pipe 203 blows air, blowing the previously entered 0.6mm seed source into the output air pipe 204 and conveying it to the activity detection component 30.

[0108] In the activity detection assembly 30, the movable baffle 307 inside the Y-type inlet pipe 302 is in a discharge state under normal conditions due to the force of the torsion spring, blocking the inlet end of the Y-type inlet pipe 302. A single 0.6mm seed source delivered from the output gas pipe 204 enters the side pipe 3022 of the Y-type inlet pipe 302 and is blocked by the movable baffle 307. After the photoelectric sensor at the side pipe 3022 detects the seed source's arrival, it transmits a signal to the control panel 2. The control panel 2 controls the electromagnet to be energized, and the movable baffle 307 switches from the discharge state to the detection state. At this time, the inlet end of the Y-type inlet pipe 302 is connected to the feed end, and the seed source enters the detection tube 304 inside the detector 301 through the feed end for radioactivity detection. The diameter of the constricted hole 3041 at the bottom of the detection tube 304 is less than 0.6mm, causing the seed source to stop and be detected at the constricted hole 3041.

[0109] After the 0.6mm seed source is tested, the control panel 2 controls the electromagnet to be de-energized, the movable baffle 307 switches from the testing state to the discharge state, blocks the inlet end of the Y-type inlet pipe 302, opens the feed end and the outlet end to connect, and at the same time the backflush airflow pipe 305 external air pump blows out the reverse airflow, and discharges the tested 0.6mm seed source from the outlet end of the Y-type inlet pipe 302.

[0110] Meanwhile, at the second work station, the second flat vibrating conveyor track 104 continues to feed 0.8mm seed material into the second feeding chamber 206. When the photoelectric sensor in the second feeding chamber 206 detects that the 0.8mm seed material has been placed, it transmits the signal to the control panel 2. The control panel 2 then controls the electric cylinder 207 to move, so that the switching plate 202 switches back to the first work station.

[0111] During the switchback to the first station, the first feed chamber 205 is aligned with the outlet of the first flat vibrating conveyor track 103 and begins to receive 0.6mm seed sources again. The second feed chamber 206 (which already contains the previously entered 0.8mm seed sources) is aligned with the air blowing pipe 203 and the output air pipe 204. The air blowing pipe 203 blows air, blowing the 0.8mm seed sources into the output air pipe 204 and conveying them to the activity detection component 30.

[0112] The activity detection component 30 performs the same detection process for 0.8mm seed sources as for 0.6mm seed sources. Detection and discharge are achieved by switching the movable baffle 307. After the photoelectric sensor at the side tube 3022 detects the seed source in place, the movable baffle 307 switches to the detection state, and the seed source enters the detection tube 304 for detection. After the detection is completed, the movable baffle 307 switches back to the discharge state, and the backflushing airflow discharges the seed source.

[0113] After testing, the seed sources are graded and then packaged. The grading starts from an activity value of 400 microcubic units, with grading intervals of 50 microcubic units and a maximum value of 1400 microcubic units, forming multiple grading zones. If seed source materials of two specifications are fed and tested at the same time, the grading intervals are set in two parts to correspond to different specifications.

[0114] In the automatic dispensing and packaging component 40, the electric guide rail 403 controls the injection conduit 404 fixed on the slider 406 to be in the initial position. The retractable stop 407 extends under the drive of the micro cylinder 408, blocking the seed source from falling. When the seed source discharged from the activity detection component 30 enters the injection conduit 404 and blocks the photoelectric sensor installed above the retractable stop 407, the photoelectric sensor transmits the seed source arrival signal to the control panel 2. The control panel 2 controls the electric guide rail 403 to move, so that the injection conduit 404 descends and inserts into the seed source collection bottle 402 of the corresponding sorting area on the rotating tray 401. At the same time, the micro cylinder 408 drives the retractable stop 407 to retract, and the seed source falls smoothly into the seed source collection bottle 402.

[0115] Based on the signal from the photoelectric sensor above the retractable stop 407, the control panel 2 counts the number of collected seeds. When the seed collection bottle 402 reaches the specified collection quantity, the motor drives the rotating tray 401 to rotate, moving the full seed collection bottle 402 to a position easily accessible to the operator. Simultaneously, the control panel 2 controls the label printer 3 to print labels, completing the labeling and sorting process. The entire process is cyclical, and through precise timing control of the various photoelectric sensors, the automatic sorting of sealed seeds is ensured to be completed efficiently, accurately, and without interference.
