Description
Technical Field
[0001] This invention relates to the field of dose measurement technology, specifically to an automated thermoluminescent personal dose measurement system and method. Background Technology
[0002] Currently, in the routine thermoluminescent dosimetry measurement process in the nuclear industry system, used thermoluminescent (TLD) crystals are manually placed into a special dosimetry card, which is then placed into a magazine. Finally, the magazine filled with dosimetry cards is placed into a dedicated thermoluminescent personal dosimetry measuring device for measurement. After the measurement, the dosimetry tablet must be manually removed, the crystal removed from the tablet, placed in a crucible, and annealed in an annealing furnace. Finally, the annealed TLD crystal is placed back into the dosimetry card to make a new tablet, which is then distributed to process personnel for use. This traditional method often suffers from drawbacks such as susceptibility to statistical errors, potential dosimetry tablet leakage, difficulty in visually identifying defective tablets, and high manpower requirements.
[0003] A search revealed that there are currently no automated measurement systems in this field in China. Therefore, this study proposes designing an automated thermoluminescence personal dosimetry measurement system. This system would replace the entire manual operation process with a high-precision automated machine, significantly improving work efficiency, reducing labor costs, enhancing measurement stability, and minimizing human error. This would fill a gap in the field and realize the automation transformation of thermoluminescence personal dosimetry measurement. Summary of the Invention
[0004] The purpose of this invention is to provide an automated thermoluminescence personal dosimetry measurement system and method, which automates the entire process of personal dosimetry tablet measurement, from statistics, cartridge loading, sample loading, measurement reading, sample unloading, tablet removal, dosimetry tablet heating and cooling, dosimetry tablet screening, and preparation of new tablets. This reduces the measurement error rate, reduces manpower, and improves measurement quality and efficiency.
[0005] The technical solution of the present invention is as follows: an automated thermoluminescence personal dosimetry measurement system, comprising an automatic slide loading module, an automatic transfer module, an automatic disassembly and assembly module, an automatic annealing module, and an automatic analysis module;
[0006] The automatic tablet loading module loads the dose tablets into the magazine; the dose tablets contain thermoluminescent crystals.
[0007] The automatic transfer module is used for magazine transfer;
[0008] The automatic disassembly and assembly module is used for disassembling and assembling thermoluminescent crystals;
[0009] The automatic annealing module is used for the annealing of thermoluminescent crystals;
[0010] The automatic analysis module is used for sorting annealed thermoluminescent crystals.
[0011] The dosing plate consists of two thin sheets with a sliding plate sandwiched between them, and the thermoluminescent crystal is embedded in the sliding plate.
[0012] The automatic loading module includes an automatic stacking device and an automatic filling device; the automatic stacking device includes a feeding device and a four-axis robotic arm. The feeding device is connected to a hopper, and the hopper is connected to a flexible vibrating plate; the automatic filling device includes a parallel motion device, an electric gripper, a slot, and a parallel electric cylinder. The parallel electric cylinder is installed on the parallel motion device. The electric gripper drives the parallel motion device, which in turn drives the parallel electric cylinder.
[0013] The automatic loading module also includes an infrared photoelectric switch and a vision device.
[0014] The automatic transfer module includes a six-axis robotic arm and grippers, an empty magazine placement area, a thermoluminescent crystal detection area, a magazine retrieval area for the thermoluminescent crystal detection equipment, and a magazine unloading box. The six-axis robotic arm and grippers place the magazines in the empty magazine placement area into the automatic loading device, and then the six-axis robotic arm and grippers transfer the magazines to the thermoluminescent crystal detection area.
[0015] The automatic transfer module also includes multiple sets of industrial cameras to observe whether there are magazines in the empty magazine placement area, automatic loading device, thermoluminescent crystal detection area, magazine unloading box, and thermoluminescent crystal disassembly and assembly device.
[0016] The automatic assembly and disassembly module includes a four-axis robotic arm, an industrial camera, a thermoluminescent crystal assembly and disassembly device, a crucible, a vibratory feeder, and a hopper; the vibratory feeder is connected to the hopper and holds the annealed thermoluminescent crystal.
[0017] The magazine is installed into the thermoluminescent crystal disassembly and assembly device. The slider in the dose tablet slides out, and the thermoluminescent crystal is located in the groove. The thermoluminescent crystal is pushed out by a parallel electric cylinder, and then placed into the crucible by a four-axis robotic arm.
[0018] The automatic annealing module includes a heating zone, a cooling zone, and a six-axis robotic arm. The six-axis robotic arm places the crucible into the heating zone for heating, and the heated thermoluminescent crystal is placed into the cooling zone for cooling and annealing before being sent to the automatic analysis module.
[0019] The automatic analysis module distinguishes between good and defective thermoluminescent crystals after firing. The good crystals are transferred to silo 308 and vibrated into a vibrating plate.
[0020] An automated method for thermoluminescent personal dosimetry measurement includes the following steps:
[0021] S1: The six-axis robotic arm and grippers place the magazines in the empty magazine placement area into the automatic loading device;
[0022] S2: Using a vision device, the four-axis robotic arm is guided to pick up the dose tablet from the flexible vibrating plate and place it into the slot of the automatic filling device.
[0023] S3: The electric gripper drives the parallel motion device, which in turn drives the parallel electric cylinder to push the dose tablet on the slot into the magazine, thus completing the dose tablet loading.
[0024] S4: After the magazine is filled with dose tablets, the six-axis robotic arm and grippers transfer the magazine to the magazine release area of the thermoluminescent crystal detection equipment. The magazine is measured in the magazine release area of the thermoluminescent crystal detection equipment. After the measurement is completed, the six-axis robotic arm and grippers transfer the magazine to the thermoluminescent crystal disassembly and assembly device.
[0025] S5: The slider in the dose tablet is slid out, and the thermoluminescent crystal is located in the groove. The thermoluminescent crystal is pushed out by the parallel electric cylinder, and the pushed-out thermoluminescent crystal is placed into the crucible by the four-axis robotic arm. The annealed thermoluminescent crystal in the vibratory plate is placed into the groove by the four-axis robotic arm, so that the annealed thermoluminescent crystal is embedded in the slider. The slider is then pushed back into the dose tablet by the parallel electric cylinder, so that the dose tablet returns to the magazine. The magazine is then moved to the magazine unloading box by the six-axis robotic arm and grippers. The individual dose tablet is knocked out of the magazine by the six-axis robotic arm and grippers and placed in the magazine unloading box.
[0026] S6: The six-axis robotic arm places the crucible into the heating zone for heating. After heating, the thermoluminescent crystal is placed into the cooling zone to cool and complete the annealing. The six-axis robotic arm then sends the annealed thermoluminescent crystal to the automatic analysis module for testing, distinguishing between good and defective products. The good products are transferred to the silo and vibrated into the vibrating plate to become new thermoluminescent crystals.
[0027] The significant advantage of this invention is that it can realize automatic loading of thermoluminescent dosing tablets, automatic dosing tablet replenishment, and complete the dosing tablet positioning, barcode scanning, and dosing tablet loading into the magazine with one click.
[0028] It can realize fully automated transfer of magazines from the empty magazine placement area to the shrapnel loading area, the magazine release area of the thermoluminescent crystal detection equipment, the crystal replacement area, the shrapnel unloading area, and the empty magazine placement area.
[0029] It can automatically disassemble old crystals in the dosimeter while simultaneously loading new crystals. It provides a crucible placement function for old crystals, ensuring they are neatly arranged in the crucible for subsequent annealing. For new crystals, it provides an automatic feeding function, automatically replenishing the container when there are no more crystals to be picked up in the flexible vibrating plate. The entire process is fully automated, with disassembly and assembly occurring simultaneously. Furthermore, it can directly remove the TLD crystal from the magazine, eliminating the need for manual removal of the dosimeter card and TLD crystal sequentially.
[0030] It can achieve automatic transfer and annealing cooling of thermoluminescent crystals without manual intervention.
[0031] This system enables automated analysis of crystals in thermoluminescent dosimeters, automatically detecting and analyzing the crystals to distinguish between good and defective products. Good crystals are recycled, while defective ones are discarded. The entire process utilizes artificial intelligence algorithms and a four-axis robotic arm to fully automate the analysis of crystal states. It can operate continuously for extended periods, effectively improving crystal analysis efficiency. Attached Figure Description

[0049] The specific technical content of the present invention will now be described with reference to the accompanying drawings;
[0050] An automated thermoluminescence personal dosimetry measurement system includes an automatic slide loading module 001, an automatic transfer module 002, an automatic disassembly and assembly module 003, an automatic annealing module 004, and an automatic analysis module 005. The automatic slide loading module 001 is responsible for personal dosimetry slide counting and magazine loading; the automatic transfer module 002 is responsible for the magazine loading and unloading processes; the automatic disassembly and assembly module 003 is responsible for the disassembly and assembly of thermoluminescent crystals; the automatic annealing module 004 is responsible for crystal heating and cooling; and the automatic analysis module 005 is responsible for sorting the annealed crystals according to their quality. These five modules work together to complete the fully automated thermoluminescence personal dosimetry measurement process.
[0051] Specifically, the magazine 110 is used to hold the dose tablet, which consists of two thin sheets with a slider 305 sandwiched between them, and the thermoluminescent crystal is embedded in the slider 305.
[0052] like Figure 2As shown, the automatic tablet loading module 001 includes an automatic stacking device and an automatic filling device 120. The automatic stacking device includes a feeding device 101, a four-axis robotic arm 102, a pneumatic component 103, and a vision device 104. The feeding device 101 is connected to a hopper 111, and the hopper 111 is connected to a flexible vibrating plate 112. Using the vision device 104, the four-axis robotic arm 102 is guided to pick up the tablets from the flexible vibrating plate 112. After completing the barcode reading function, the tablets are placed into the slots 108 of the automatic filling device 120.
[0053] Specifically, the pneumatic component 103 provides power to the four-axis robotic arm 102;
[0054] like Figure 3 As shown, the automatic loading device 120 includes a parallel motion device 105, an electric gripper 106, and a parallel electric cylinder 109. The parallel electric cylinder 109 is mounted on the parallel motion device 105. The electric gripper 106 drives the parallel motion device 105, which in turn drives the parallel electric cylinder 109 to push the dose tablet on the slot 108 into the magazine 110, thus completing the automatic loading of the dose tablet.
[0055] Specifically, the parallel electric cylinder 109 is J-shaped, with the top used to push the dosage tablet into the magazine 110;
[0056] Specifically, the infrared photoelectric switch 107 serves as an infrared identification device;
[0057] The specific process is as follows:
[0058] 1) The staff puts the tablets into the hopper 111, which is tilted at 5° to the flexible vibrating plate 112. The hopper will automatically replenish the tablets into the flexible vibrating plate 112 at an average speed of 3cm / s through the vibration of the motor below at regular intervals. The vibration lasts for 3 seconds.
[0059] 2) The expected probability of the dose tablets being face up when poured from the hopper 111 into the flexible vibrating plate 112 is 1 / 2. The four-axis robotic arm 102 will automatically identify the face-up dose tablets and pick them up one by one from top to bottom and from left to right. After all the face-up dose tablets in the plate have been picked up, the flexible vibrating plate 112 will automatically vibrate. The vibration frequency is just enough to make the dose tablets flip over. The vibration lasts for 3 seconds. With the hopper 111 being automatically replenished periodically, the number of dose tablets in the plate can be kept in dynamic balance, and the expected probability of face up remains at 1 / 2. The four-axis robotic arm 102 picks up the dose tablets in the next round, and so on.
[0060] 3) An industrial camera is installed above the flexible vibrating plate 112. The industrial camera uses deep learning to input a large number of sample dose tablets (face up) into the large model simulation software, which can simulate the precise shape of the dose tablets. When the camera recognizes the dose tablet again, it will mark the target point position of the dose tablet (at 1 / 2 of the length and 1 / 2 of the width of the dose tablet) in the image coordinate system of the camera coordinate system, and set it as (a0, b0, h0). Through the coordinate system scaling factor K1 and the deviation factor K2, the coordinates of the target point (a, b, h0) in the coordinate system of the four-axis robotic arm 102 are obtained, where h0 is fixed. The coordinates are input into the four-axis robotic arm 102 for the four-axis robotic arm to pick up and turn the dose tablet attitude to the set position.
[0061] 4) After the four-axis robotic arm 102 picks up the dose tablet, it moves above the barcode reader 113 to scan and identify the barcode of the dose tablet, and matches the dose tablet and barcode ID one by one and saves it to the database.
[0062] 5) An industrial camera is installed below the automatic loading device 120. The four-axis robotic arm 102 clamps the dose tablet to this location. The industrial camera performs secondary positioning compensation on the absorbed dose tablet to ensure that the attitude of the dose tablet and the attitude of the magazine 110 are kept horizontal. Then the dose tablet is placed into the slot 108.
[0063] 6) An infrared photoelectric switch 107 is provided on the slot 108. When the dose tablet is placed into the slot 108, the infrared photoelectric switch 107 will be triggered and a start command will be fed back to the motor control system. Upon receiving the command, the parallel electric cylinder 109 will push the dose tablet into the magazine 110 for loading. When the magazine is full, the parallel electric cylinder 109 will repeat the pushing operation to prevent the dose tablet from popping out due to vibration of the flexible vibrating plate 112, which could cause the magazine 110 to fail to close.
[0064] The magazine has 18 layers, each holding one dose tablet. After the previous dose tablet is loaded, the slot partition moves down one notch and repeats the first step until the magazine is completely full.
[0065] like Figure 4 As shown, the automatic transfer module 002 includes a six-axis robotic arm and gripper 201, multiple sets of industrial cameras 202, an empty magazine placement area 204, a thermoluminescent crystal detection area 206, a magazine retrieval area for thermoluminescent crystal detection equipment 207, and a magazine unloading box 208.
[0066] Specifically, multiple sets of industrial cameras 202 are used to observe whether there is a magazine 110 in the empty magazine placement area 204, automatic loading device 120, thermoluminescent crystal detection area 206, magazine unloading box 208, and thermoluminescent crystal disassembly and assembly device 303, thereby determining the gripping action of the six-axis robotic arm and gripper 201.
[0067] Specifically, such as Figure 9 As shown, the automatic transfer module 002 supports five control commands, C1 to C5, with each command corresponding to a set of control actions. For example, when the host computer sends command C2, the six-axis robotic arm and gripper 201 pick up the magazine 110 from the automatic loading device 120, transfer it to the thermoluminescent crystal detection area 206, and then place it down.
[0068] The above 5 steps complete the closed loop of the entire process, from the empty magazine placement area (origin) back to the empty magazine placement area (end point).
[0069] The six-axis robotic arm and gripper 201 place the magazine 110 in the empty magazine placement area 204 into the automatic loading device 120. After the magazine 110 is filled with dosage tablets, the six-axis robotic arm and gripper 201 transfer the magazine 110 to the thermoluminescent crystal detection area 206. The magazine 110 is measured in the thermoluminescent crystal detection area 206. After the measurement is completed, the six-axis robotic arm and gripper 201 transfer the magazine 110 to the thermoluminescent crystal disassembly and assembly device 303.
[0070] like Figure 5 As shown, the automatic disassembly and assembly module 003 includes a four-axis robotic arm 301, an industrial camera 302, a thermoluminescent crystal disassembly and assembly device 303, a crucible 306, a vibratory feeder 307, and a hopper 308; wherein the vibratory feeder 307 is connected to the hopper 308 and holds the new thermoluminescent crystal after annealing.
[0071] like Figure 6 As shown, the magazine 110 is located in the thermoluminescent crystal loading and unloading device 303. The slider 305 in the dose sheet slides out, and the thermoluminescent crystal is located in the groove 309. The thermoluminescent crystal is pushed out by the parallel electric cylinder 304, and the old thermoluminescent crystal is placed into the crucible 306 by the four-axis robotic arm 301. The new (annealed) thermoluminescent crystal in the vibratory plate 307 is placed into the groove 309 by the four-axis robotic arm 301, thereby embedding the new thermoluminescent crystal in the slider 305. The parallel electric cylinder 304 pushes the slider 305 back into the dose sheet, so that the dose sheet returns to the magazine 110. The magazine 110 is then moved to the magazine unloading box 208 by the six-axis robotic arm and the gripper 201, and the single dose sheet is knocked out of the magazine 110 and placed in the magazine unloading box 208 by the six-axis robotic arm and the gripper 201.
[0072] Specifically, the thermoluminescent crystals in crucible 306 are arranged neatly, and when a certain number of thermoluminescent crystals are arranged in crucible 306, they are used for subsequent annealing.
[0073] Specifically, the dynamic balance between the annealed thermoluminescent crystal and the thermoluminescent crystal used for subsequent annealing;
[0074] like Figure 7As shown, the automatic annealing module 004 includes a heating zone 403, a cooling zone 404, and a six-axis robotic arm 405. The six-axis robotic arm 405 places the crucible 306 into the heating zone 403 for heating (250 degrees Celsius, ten minutes). The heated thermoluminescent crystal is then placed in the cooling zone 404 to cool and complete the annealing. The six-axis robotic arm 405 sends the annealed thermoluminescent crystal to the automatic analysis module 005 for testing to distinguish between good and defective products. The good products are transferred to the silo 308 and vibrated into the vibrating plate 307 to become new thermoluminescent crystals. Then, 301 places the new thermoluminescent crystals into the thermoluminescent crystal assembly / disassembly device 303 for assembly.
[0075] The specific analysis process of the automatic analysis module 005 is as follows:
[0076] 1. Crystal defect analysis: Some crystals are in normal condition on both sides after annealing and cooling, but are missing some areas. In this case, computer vision algorithm is used to identify and calculate the area of the 2D image of the crystal. If the crystal area is smaller than the normal value, the subsequent detection algorithm can be skipped and the crystal can be discarded directly, thereby simplifying and speeding up the identification process.
[0077] 2. Crystal front analysis: After the crystal is annealed and cooled in a high-temperature furnace, a detection algorithm is used to locate the crystal in the crucible. A classification and recognition algorithm is used to analyze the upper surface of the crystal to determine the crystal state. When the upper surface is determined to be defective, a four-axis robotic arm is guided to the top of the crystal and picks it up. The crystal is then directly discarded to the waste position. If the upper surface is determined to be good, the state of the lower surface needs to be judged.
[0078] 3. Crystal reverse side analysis: When the front side of the crystal is good, the robotic arm picks up the crystal and moves it to the secondary judgment position. The lower camera 505 analyzes the reverse side of the crystal. If the reverse side of the crystal is defective at this time, the crystal is discarded to the waste position. If it is judged to be good, the crystal is moved to the material storage area 506 for recycling.
[0079] Specifically, such as Figure 8 As shown, when the thermoluminescent crystal is white and has no obvious discoloration (usually yellowing), and the surface is not roughened and there is no obvious damage, it is judged as a good product; while if any of the following occurs, such as discoloration, surface roughness, or damage, it is judged as a defective product.

An automated method for thermoluminescent personal dosimetry measurement, using the automated thermoluminescent personal dosimetry measurement system as described in claim 6, characterized in that, Includes the following steps: S1: The six-axis robotic arm and gripper (201) place the magazine (110) in the empty magazine placement area (204) into the automatic loading device (120); S2: By using a vision device (104), the four-axis robotic arm (102) is guided to pick up the dose tablet from the flexible vibrating plate (112) and then place the dose tablet into the slot (108) of the automatic filling device (120); S3: The electric gripper (106) drives the parallel motion device (105), which in turn drives the parallel electric cylinder (109) to push the dose tablet on the slot (108) into the magazine (110), thus completing the dose tablet loading. S4: After the magazine (110) is filled with dose tablets, the six-axis robotic arm and gripper (201) transfer the magazine (110) to the thermoluminescent crystal detection area (206). The magazine (110) is measured in the thermoluminescent crystal detection area (206). After the measurement is completed, the six-axis robotic arm and gripper (201) transfer the magazine (110) to the thermoluminescent crystal disassembly and assembly device (303). S5: The slider (305) in the dose tablet is slid out, and the thermoluminescent crystal is located in the groove (309). The thermoluminescent crystal is pushed out by the parallel electric cylinder (304), and the pushed-out old thermoluminescent crystal is placed into the crucible (306) by the four-axis robotic arm (301). The annealed thermoluminescent crystal in the vibrating plate (307) is placed into the groove (309) by the four-axis robotic arm (301), so that the annealed thermoluminescent crystal is embedded in the slider (305). The slider (305) is pushed back into the dose tablet by the parallel electric cylinder (304), so that the dose tablet returns to the cartridge (110). The cartridge (110) is moved to the cartridge unloading box (208) by the six-axis robotic arm and the gripper (201), and the single dose tablet is knocked out from the cartridge (110) by the six-axis robotic arm and the gripper (201) and placed in the cartridge unloading box (208). S6: The six-axis robotic arm (405) places the crucible (306) into the heating zone (403) for heating. The heated thermoluminescent crystal is placed in the cooling zone (404) for cooling to complete the annealing. The six-axis robotic arm (405) sends the annealed thermoluminescent crystal to the automatic analysis module (005) for detection to distinguish between good and defective products. The good products are transferred to the silo (308) and vibrated into the vibrating plate (307) to become new thermoluminescent crystals.
