DETAILED DESCRIPTION

[0019] The embodiments of the present application will be further described in conjunction with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine the different embodiments or examples described in the present application and the features of the different embodiments or examples without contradiction.

[0024] In the field of deep space exploration and underwater scientific exploration, traditional energy cannot provide continuous power supply in deep space, deep sea and other harsh environments. As a device that converts the heat of radioactive isotope decay into electrical energy through thermoelectric effect, the isotope battery can provide continuous power supply in harsh environments. Among them, the isotope battery usually includes a heat source assembly for providing heat energy. As the core component of the isotope battery, the heat source assembly determines the comprehensive performance and structural characteristics of the isotope battery.

[0025] The powder metallurgy method is an important method for preparing the heat source assembly. The prepared heat source assembly is basically composed of a source core, a first cladding and a second cladding. By cold pressing and sintering the radioactive material, the volume of the source core can be reduced and the density of the source core can be improved. The sintered ceramicized source core has better environmental safety. The double-layer welding packaging of the first cladding and the second cladding ensures that the radioactive material does not leak to the outside during storage, transportation and use, and ensures the environmental safety of the radioactive source.

[0026] The powder metallurgy method is an important method for preparing the heat source assembly.

The sintered ceramicized source core has better environmental safety. The double-layer welding packaging of the first cladding and the second cladding ensures that the radioactive material does not leak to the outside during storage, transportation and use, and ensures the environmental safety of the radioactive source.

[0027] In the related art, in the production and manufacturing process of the heat source assembly, for the plutonium-238 isotope, although the external exposure dose rate is low, due to the large amount of operation, the complex process and the long operation time, the ionizing radiation safety of the operator still has great challenges. In addition, it is found in test and test that the damage of plutonium-238 material to the glove material is extremely obvious. In the case of contacting powder, ordinary lead gloves will be damaged and cracked after about 1 week of use, causing contamination or aerosol pollution risk. Therefore, it is risky and inefficient to produce and manufacture plutonium-238 isotope heat source assemblies in a glove box.

[0028] For strontium-90 isotope, due to strong ionization radiation, it must be prepared and operated in a hot cell environment. However, due to the limitation of the nearly 1-meter-thick glass window in the hot cell environment, the view is not clear, and the risk of large-scale contamination of the hot cell surface caused by spilling during the transfer of the pellets and the source core is extremely high. The assembly between the source core and the first cladding and the second cladding is difficult to implement due to the extremely small gap (generally <1mm). The use of a camera can improve the operation accuracy, but in a strong radiation environment, the camera sensor is extremely easy to damage, making it difficult to continue.

[0029] In order to ensure the safety of personnel and the environment, for the strong radiation or high activity of alpha, beta, gamma, neutron source, the powder metallurgy preparation (i.e. the preparation of the heat source assembly) should adopt the hot cell preparation to solve the problem of unreliable safety measures of the operator, and the higher precision mechanical automation control means should be used to assist in view of the high radiation dose and the poor operation precision of the hot cell manipulator, and the hot cell manipulator only participates in the transfer activities with low risk of spilling.

[0030] It should be noted that the hot cell manipulator is a pure mechanical structure, which is strong against radiation and has high reliability. It is particularly suitable for long-distance material transportation and is directly operated by an operator. Since it is manually operated, it is greatly affected by the technical level of the operator. It is very difficult to move (grip strength will damage the pellets) and assemble (first cladding and second cladding assembly, cladding and cover assembly, source core and first cladding assembly, etc.) of samples with small tolerances. In addition, it is not suitable for directly gripping the mechanical hand with strong surface pollution (such as pellets), which will pollute the mechanical hand clamps. Subsequent gripping of other objects will pollute other objects. The tool or clamp for gripping the source core and the pellets is special in principle. The suitable transferred objects include raw material tanks, sundries, disc pieces containing pellets / source cores, and welded first cladding and second cladding.

[0031] Based on the above, the embodiment of the present application provides a preparation device 10 of a heat source assembly 100. Please refer to Figures 1 to 17 The heat source assembly 100 includes a source core 101 and a first cladding 102. The first cladding 102 includes a first shell 1021 and a first cover 1022. The preparation device 10 includes a rack 11, a measurement module 12, an assembly table 13, a welding module 14, and a first transfer module 15. The measurement module 12 is arranged on the rack 11 and is used to measure the size of the source core 101. The assembly table 13 is arranged on the rack 11. The first shell 1021 is placed on the assembly table 13. The welding module 14 is arranged on the rack 11, and the welding module 14 is used to weld the assembled first shell 1021 and the first cover 1022 into the first cladding 102. The first transfer module 15 is movably arranged on the rack 11. The first transfer module 15 is used to transfer the measured source core 101 into the first shell 1021 on the assembly table 13, assemble the first cover 1022 and the first shell 1021, and transfer the assembled first shell 1021 and the first cover 1022 to the welding module 14.

[0032] It should be noted that the source core 101 in the heat source assembly 100 can also be referred to as a heat source. The source core 101 can generate heat energy through radioactive isotope decay.

[0033] The heat source assembly 100 is an ionizing radiation source prepared by using radioactive substances.

[0034] The heat source assembly 100 comprises a source core 101 and a first cladding 102, and the first cladding 102 comprises a first shell 1021 and a first cover 1022. The first shell 1021 is sleeved outside the source core 101, and the first cover 1022 can be combined with the first shell 1021 to completely cover the source core 101 inside the first shell 1021.

[0035] The rack 11 serves as a common platform for carrying the measuring module 12, the assembly table 13, the welding module 14 and the first transfer module 15, can assemble other components of the preparation device 10 into an integrated whole, and can improve the structural reliability and stability of the preparation device 10.

[0036] The rack 11 can be placed on the ground, fixed relative to the ground or slidable, thereby realizing the fixation and movement of the entire preparation device 10, which is not limited herein.

[0037] Exemplarily, the preparation device 10 further comprises a sintering furnace 20, which can perform high-temperature sintering on the core block 400 formed by powder compression molding, so that the core block 400 is ceramicized or alloyed to form the source core 101. The furnace door 201 of the sintering furnace 20 can be automatically opened and closed by an automatic support rod. The sintering furnace 20 can be selected according to process conditions such as use atmosphere, temperature zone, temperature rising capacity and use environment, and is a mature product on the market.

[0038] That is, the source core 101 in the present application is the core block 400 after high-temperature sintering, and the measurement of the size of the source core 101 and the subsequent assembly and welding are all processes after high-temperature sintering of the sintering furnace 20.

[0039] Exemplarily, the sintering temperature of the sintering furnace 20 can be set to 400℃ (for aluminum green body) or 500℃ (for strontium carbonate green body), and the process condition is vacuum sintering for 3-5 hours. After sintering is completed, cooling to room temperature is required.

[0040] The measuring module 12 is arranged on the rack 11 and is used for measuring the size of the source core 101. In this way, the source core 101 that does not meet the requirements can be excluded, the assembly of the source core 101 and the first cladding 102 can be improved, the situation that the source core 101 is too large to be assembled into the first shell 1021 can be avoided, and the assembly efficiency can be improved.

[0041] The shape of the source core 101 is not limited, and can be a cube, a cylinder, a prism or the like.

[0042] The assembly table 13 is arranged on the rack 11, and specifically, the assembly table 13 can be fixed on the rack 11.

[0043] The first shell 1021 is placed on the assembly table 13, specifically, a plurality of first shells 1021 can be placed on the assembly table 13, and the first shell 1021 is prepared on the assembly table 13.

[0044] The welding module 14 is arranged on the rack 11, which can be fixed on the rack 11 or movably arranged on the rack 11.

[0045] The welding module 14 is used to weld the assembled first shell 1021 and the first cover 1022 into the first package 102, so as to realize automatic welding, reduce manual operation and improve production efficiency.

[0046] The first transfer module 15 is movably arranged on the rack 11, which means that the first transfer module 15 can move on the rack 11.

[0047] The first transfer module 15 is used to transfer the measured source core 101 into the first shell 1021 on the assembly table 13, assemble the first cover 1022 and the first shell 1021, and transfer the assembled first shell 1021 and the first cover 1022 to the welding module 14, that is, the first transfer module 15 has at least the above three functions. The first transfer module 15 is used to transfer the measured source core 101 into the first shell 1021 on the assembly table 13, which means that the measured source core 101 is transferred from the measuring module 12 to the assembly table 13, and the source core 101 can be driven to be loaded into the first shell 1021; the first cover 1022 and the first shell 1021 are assembled, which can be assembled on the assembly table 13 or other workstations, so that the first cover 1022 and the first shell 1021 are temporarily fixed, so as to facilitate subsequent transfer and welding operations.

[0048] The preparation apparatus 10 provided in this application embodiment, by setting a measurement module 12 on the frame 11, can measure the dimensions of the source core 101 before assembly, improving the smoothness of assembly. By setting an assembly table 13 on the frame 11, the assembly table 13 can provide an operating platform and space for assembling the source core 101 and the first shell 102. By movably setting a first transfer module 15 on the frame 11, the first transfer module 15 can not only realize the material transfer between the measurement module 12 and the assembly table 13, and between the assembly table 13 and the welding module 14, but also assemble the source core 101 and the first shell 1021. Assembling the first cover 1022 with the first housing 1021 containing the source core 101 reduces manual operation during assembly and transfer, improves process stability, better realizes key process steps, enhances the automation level of the preparation device 10, and increases the production efficiency of the heat source component 100. This is conducive to the long-term mass production of high-dose radioactive sources. At the same time, it can also improve the difficulties in operation for production personnel caused by the low precision of the manipulator in the hot chamber and the situation where radioactive materials are easily spilled during the transfer of the source core 101, thereby reducing the risk of large-scale radioactive contamination on the surface of the hot chamber.

[0049] For example, the first transfer module 15 can be a PLC-controlled moving mechanism. A Programmable Logic Controller (PLC) is a general-purpose industrial automatic control device developed by integrating computer technology, automatic control technology, and communication technology, with a microprocessor as its core. The advantages of a PLC-controlled moving mechanism are precise control and, theoretically, the ability to move any object. However, for long-distance transport, it requires lead screws and long control lines, and its stability is poor in the hot chamber (the cables become brittle due to irradiation). Therefore, in this solution, it is best to use a PLC-controlled moving mechanism for moving fragile samples (such as core block 400) (too much gripping force will damage core block 400), assembling samples with small tolerances (assembling the first casing 102 with the second casing 103, the casing with the cover, the source core 101 with the first casing 102, etc.), and moving samples with strong surface contamination (such as core block 400). It can also be used in conjunction with a hot chamber robot to complete long and short-distance movements.

[0050] For example, the first transfer module 15 can transfer source cores 101 whose dimensions do not meet the requirements after measurement by the measurement module 12, specifically those whose dimensions are larger than the accommodating size of the first casing 102, from the measurement module 12 to the defective product area, thus excluding source cores 101 that do not meet the size requirements from the assembly process.

[0051] For example, three source cores 101 and one first cover 1022 can be picked up or clamped and assembled with the first housing 1021 on the assembly table 13.

[0052] In some embodiments, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 15 , the heat source assembly 100 further comprises a second cladding 103 sleeved outside the first cladding 102. The second cladding 103 comprises a second shell 1031 and a second cover 1032. The assembly station 13 has a first assembly station 13a and a second assembly station 13b. The first assembly station 13a is placed with the first shell 1021. The second assembly station 13b is placed with the second shell 1031. The first transfer module 15 is used to transfer the first cladding 102 into the second shell 1031 of the second assembly station 13b, and assemble the second shell 1031 and the second cover 1032 into the second cladding 103.

[0053] The second cladding 103 is a second layer of shell outside the heat source assembly 100. The heat source assembly 100 has the source core 101, the first cladding 102 and the second cladding 103 from inside to outside, so as to improve the safety of the heat source assembly 100 during transportation, storage and use by double-layer packaging, and reduce the probability of radioactive material leakage.

[0054] The first transfer module 15 is used to transfer the first cladding 102 into the second shell 1031 of the second assembly station 13b, and assemble the second shell 1031 and the second cover 1032 into the second cladding 103. That is to say, on the second assembly station 13b, the first transfer module 15 has at least two processes, one is to assemble the packaged source core 101 and the first cladding 102 into the second shell 1031, and the other is to assemble the second shell 1031 with the first cladding 102 and the second cover 1032.

[0055] The first assembly station 13a is placed with the first shell 1021, that is, the first shell 1021 is always placed on the assembly station, and the first transfer module 15 does not need to take the first shell 1021 from other places, which can simplify the process operation. The second assembly station 13b is placed with the second shell 1031, and the first transfer module 15 does not need to take the second shell 1031 from other places, which can further simplify and reduce the processes of the first transfer module 15, and improve the assembly efficiency.

[0056] In this embodiment, by setting the first assembly station 13a and the second assembly station 13b on the assembly table 13, the first cladding 102 and the second cladding 103 are assembled in different stations respectively, which can improve the situation that the first transfer module 15 is prone to process errors in the process of automatic assembly, and is conducive to the automatic operation of the first transfer module 15. At the same time, the first assembly station 13a and the second assembly station 13b are both on the assembly table 13, which can reduce the distance of transferring materials between the two positions, and is conducive to improving the assembly efficiency.

[0057] Exemplarily, the first assembly station 13a and the second assembly station 13b can be integrated on the same assembly table 13, or can be respectively set on different assembly tables 13. For being respectively set on different assembly tables 13, the first assembly station 13a and the second assembly station 13b can be placed in different hot chambers, so as to carry out partition management of different pollution levels of articles, which is conducive to reducing the pollution residues on the surface of the components of the heat source assembly 100 in the process of assembling the heat source assembly 100.

[0058] In some embodiments, referring to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 , the first transfer module 15 includes a moving seat 151, a clamping assembly 152, and a suction cup assembly 153. The moving seat 151 is movably arranged on the rack 11. The clamping assembly 152 is movably arranged on the moving seat 151. The clamping assembly 152 is used to clamp the assembled first shell 1021 and the first cover 1022 to transfer to the welding module 14, and to transfer the first cladding 102 to the second shell 1031 in the second assembly station 13b. The suction cup assembly 153 is movably arranged on the moving seat 151, and is used to suck the measured source core 101 and transfer it to the first shell 1021 on the first assembly station 13a, and to assemble the first cover 1022 and the first shell 1021, and to assemble the second shell 1031 and the second cover 1032 in the second assembly station 13b.

[0059] Movable arrangement means that relative motion can occur between two pieces. For example, the moving seat 151 is movably arranged on the rack 11, which means that the moving seat 151 and the rack 11 can move relative to each other. The clamping assembly 152 is movably arranged on the moving seat 151, which means that the clamping assembly 152 can move relative to the moving seat 151. The suction cup assembly 153 is movably arranged on the moving seat 151, which means that the suction cup assembly 153 can move relative to the moving seat 151. In this way, the moving seat 151 can indirectly move the suction cup assembly 153 and the clamping assembly 152 relative to the rack 11, while the suction cup assembly 153 and the clamping assembly 152 can independently move relative to the moving seat 151, which can improve the flexibility of the first transfer module 15.

[0060] The clamping assembly 152 can be used to clamp any object, for example, the first package 102, the first shell 1021, the first cover 1022, the source core 101, the second package 103, the second shell 1031 or the second cover 1032, etc.

[0061] Exemplarily, the clamping assembly 152 can also clamp the assembled second shell 1031 and the second cover 1032, i.e., the second package 103, and transfer to the welding module 14 for welding operation.

[0062] The suction cup assembly 153 can be used to suck any object, for example, the source core 101, the first cover 1022 or the second cover 1032. The source core 101 sucked can be before or after measurement. For the source core 101 sucked before measurement, it can be specifically that the sintered source core 101 is sucked from the disc 23 used to assemble the sintered source core 101, and is transferred to the measurement module 12 in cooperation with the movement of the moving seat 151.

[0063] The suction cup assembly 153 transfers the measured source core 101 into the first shell 1021 on the first assembly station 13a, including at least two processes of transferring the source core 101 from the measurement module 12 to the assembly table 13 and assembling the source core 101 into the first shell 1021.

[0064] Exemplarily, the suction cup assembly 153 can cooperate with the moving seat 151 to push the source core 101 into the first shell 1021 along the axial direction of the first shell 1021.

[0065] The suction cup assembly 153 can assemble the first cover 1022 and the first shell 1021, which means that the suction cup assembly 153 can cooperate with the moving seat 151 to assemble the first cover 1022 and the first shell 1021.

[0066] The suction cup assembly 153 can assemble the second shell 1031 and the second cover 1032 at the second assembly station 13b, which also means that the suction cup assembly 153 cooperates with the moving seat 151 to drive the second cover 1032 to abut and assemble with the second shell 1031.

[0067] Exemplarily, the suction cup assembly 153 can also cooperate with the moving seat 151 to drive the first package 102 to extend into the second shell 1031.

[0068] Exemplarily, the first assembly station 13a of the assembly table 13 is provided with a first limiting part 13c, which unidirectionally limits the first shell 1021 at least at one end in the axial direction of the first package shell 102, so that the suction cup assembly 153 does not need to be fixed by additional operation when pushing the source core 101 into the first shell 1021 or assembling the first cover 1022 along the axial direction of the first package shell 102, which is beneficial to the assembly of the source core 101 and the first shell 1021 or the assembly between the first cover 1022 and the first shell 1021.

[0069] Exemplarily, the second assembly station 13b of the assembly table 13 is provided with a second limiting part 13d, which unidirectionally limits the second shell 1031 at least at two ends in the axial direction of the second package shell 103, so that the suction cup assembly 153 does not need to be fixed by additional operation when assembling the second cover 1032 along the axial direction of the second package shell 103, which is beneficial to the assembly between the second cover 1032 and the second shell 1031.

[0070] In some embodiments, referring to Figure 5 and Figure 8 The moving seat 151 includes a first sliding table 1511 and a second sliding table 1512. The first sliding table 1511 is arranged on the rack 11 and slidably connected with the rack 11 along a first direction. The second sliding table 1512 is arranged on the first sliding table 1511 and slidably connected with the first sliding table 1511 along a second direction. The clamping assembly 152 and the suction cup assembly 153 are arranged on the second sliding table 1512. The first direction intersects the second direction.

[0071] It should be noted that while the first sliding table 1511 is arranged on the rack 11 and slidably connected with the rack 11 along the first direction, the second sliding table 1512 is arranged on the first sliding table 1511 and slidably connected with the first sliding table 1511 along the second direction, so that the second sliding table 1512 can indirectly move relative to the rack 11 along the first direction, realizing the movement of the second sliding table 1512 along the first direction and the second direction.

[0072] The first direction intersects the second direction, which means that the first direction is not parallel to the second direction. Exemplarily, the first direction is perpendicular or substantially perpendicular to the second direction.

[0073] Exemplarily, the first direction can be the width direction of the preparation device 10, and the second direction can be the length direction of the preparation device 10.

[0074] It should be noted that the dimensions of different components in the three directions of the same absolute coordinate system are different. Generally, the length, width and height of an object are determined according to the dimensions of the object in the three directions, and the length is usually greater than the width.

[0075] Exemplarily, Figures 1 to 16 R1 in the R1 direction can be a width direction of the preparation device 10, Figures 1 to 16 R2 in the R2 direction can be a length direction of the preparation device 10.

[0076] In this embodiment, by splitting the moving seat 151 into the first sliding table 1511 and the second sliding table 1512, the first sliding table 1511 and the second sliding table 1512 can move in two different directions respectively, so that the flexible movement of the clamping assembly 152 and the suction cup assembly 153 relative to the rack 11 is realized, and the flexibility of the clamping assembly 152 and the suction cup assembly 153 is improved.

[0077] In some embodiments, referring to Figure 5 and Figure 8 , the clamping assembly 152 includes a first lifting unit 1521 and a first clamping jaw 1522. The first lifting unit 1521 is arranged on the second sliding table 1512. The first lifting unit 1521 is used to drive the first clamping jaw 1522 to slide relative to the second sliding table 1512 along a third direction. The first direction, the second direction and the third direction intersect with each other.

[0078] Exemplarily, the first lifting unit 1521 can include a driving end and a fixed end. The fixed end is fixedly connected with the second sliding table 1512, and the driving end is movable relative to the fixed end and is connected with the first clamping jaw 1522, so as to drive the first clamping jaw 1522 to slide relative to the second sliding table 1512 along the third direction.

[0079] The first direction, the second direction and the third direction intersect with each other, which means that the first direction, the second direction and the third direction are not parallel to each other. Exemplarily, the first direction, the second direction and the third direction are completely perpendicular or approximately perpendicular to each other.

[0080] Exemplarily, the third direction can be a height direction of the preparation device 10.

[0081] Exemplarily, Figures 1 to 16 R3 in the R3 direction can be a height direction of the preparation device 10.

[0082] Exemplarily, the first lifting unit 1521 can be an execution unit such as a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc., which is not limited here.

[0083] Here, by arranging the first lifting unit 1521 and the first clamping jaw 1522, the first clamping jaw 1522 can slide relative to the second sliding table 1512 along the third direction, and the flexibility of the first clamping jaw 1522 can be further improved.

[0084] In some embodiments, referring toFigure 5 and Figure 8 The suction cup assembly 153 includes a second lifting unit 1531 and a suction cup unit 1532. The second lifting unit 1531 is arranged on the second sliding table 1512. The second lifting unit 1531 is configured to drive the suction cup unit 1532 to slide relative to the second sliding table 1512 along a third direction.

[0085] It can be understood that the second lifting unit 1531 can also include a driving end and a fixed end. The fixed end is fixedly connected with the second sliding table 1512, and the driving end is movable relative to the fixed end and connected with the suction cup unit 1532, so as to drive the suction cup unit 1532 to slide relative to the second sliding table 1512 along the third direction, thereby improving the flexibility of the suction cup unit 1532.

[0086] Exemplarily, the second lifting unit 1531 can be an execution unit such as a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc., which is not limited herein.

[0087] In some embodiments, referring to Figure 5 and Figure 8 The suction cup unit 1532 includes a suction cup seat 15321 and a suction cup execution element 15322. The suction cup seat 15321 is arranged on the second lifting unit 1531. The suction cup seat 15321 is configured to drive the suction cup execution element 15322 to rotate relative to the suction cup seat 15321.

[0088] In this embodiment, by arranging the suction cup seat 15321 and the suction cup execution element 15322, the suction direction of the suction cup execution element 15322 can be changed, thereby improving the flexibility of the suction cup unit 1532.

[0089] In some embodiments, referring to Figure 5 , 8 , 16, the measurement module 12 includes a measurement table 121, a first measurement unit 122, a second measurement unit 123, and a third measurement unit 124. The measurement table 121 is arranged on the rack 11. The first measurement unit 122 and the second measurement unit 123 are arranged on the measurement table 121 and can measure the size of the source core 101 along a first direction and a second direction, respectively. The third measurement unit 124 is arranged on the moving seat 151 and can measure the size of the source core 101 along a third direction. The first direction, the second direction, and the third direction intersect with each other.

[0090] The measurement table 121 is fixedly connected with the rack 11 and can be integrally formed with the rack 11 or can be a split design, which is not limited herein.

[0091] The measurement table 121 can be used to place the first cover 1022 and the second cover 1032 to be assembled in addition to the source core 101 to be measured.

[0092] In this embodiment, the sizes in two different directions are measured by the first measurement unit 122 and the second measurement unit 123 arranged on the measurement table 121, and the size in a third direction is measured by the third measurement unit 124 arranged on the moving seat 151 of the first transfer module 15. In this way, the sizes in at least three directions can be obtained, the measurement efficiency is improved, and the accuracy and reliability of the size evaluation of the source core 101 are improved, thereby improving the production efficiency.

[0093] For example, the third limiting part 121a and the fourth limiting part 121b are arranged on the measurement table 121, and the source core 101 can be limited when the first measurement unit 122 and the second measurement unit 123 measure the size of the source core 101 in the first direction and the second direction, respectively, thereby improving the measurement efficiency of the source core 101.

[0094] For example, after the measurement module 12 measures the size of the source core 101, the size of the source core 101 can be measured and reviewed by using the electronic vernier caliper, and the source core 101 can be returned to the original position after the review.

[0095] The third measurement unit 124 is arranged on the moving seat 151, and specifically, the third measurement unit 124 can be arranged on the second sliding table 1512.

[0096] For example, the third measurement unit 124 includes a third lifting unit 1241 and a measurement execution part 1242, the third lifting unit 1241 is connected with the second sliding table 1512 and can drive the measurement execution part 1242 to slide relative to the second sliding table 1512 in the third direction.

[0097] For example, the first measurement unit 122, the second measurement unit 123, and the third measurement unit 124 are respectively provided with displacement sensors, and real-time data can be obtained.

[0098] For example, the first measurement unit 122, the second measurement unit 123, and the third measurement unit 124 include a lead screw and a sliding block mechanism, and stepless measurement can be achieved.

[0099] Here, the third measurement unit 124 can be arranged on the second sliding table 1512 together with the clamping assembly 152 and the suction cup assembly 153, so that when the suction cup assembly 153 sucks and transfers the source core 101 to be measured to the measurement table 121, the third measurement unit 124 is also above the measurement table 121, which is beneficial to the direct size detection of the source core 101 by the third measurement unit 124, can reduce and simplify the control stroke and steps, and is beneficial to improving the production efficiency.

[0100] In some embodiments, please refer to Figures 1 to 4 , Figure 6 , Figure 14 and Figure 9The preparation device 10 further comprises a pressing module 16, a second transfer module 17 and a first placement table 18. The pressing module 16 and the first placement table 18 are arranged on the rack 11. The second transfer module 17 is movably arranged on the rack 11. The first placement table 18 is used for placing the powder bottle 300. The second transfer module 17 is used for transferring the powder bottle 300 to the pressing module 16. The pressing module 16 is used for pressing the powder in the powder bottle 300 into the briquette 400.

[0101] It should be noted that the pressing module 16 can include a frame body 161, a die 162, an upper pressing head 163, a lower pressing head 164, an upper cylinder body 165 and a lower cylinder body 166. The die 162 is formed with a pressing cavity 1621a. The frame body 161 is fixedly connected to the rack 11. The upper pressing head 163 and the lower pressing head 164 are respectively located on both sides of the die 162 along the third direction and are respectively in sliding fit with the frame body 161 along the third direction. The upper cylinder body 165 can drive the upper pressing head 163 to reciprocate along the third direction. The lower cylinder body 166 can drive the lower pressing head 164 to reciprocate along the third direction. The powder-like material in the pressing cavity 1621a is pressed into the briquette 400 by the movement of the upper pressing head 163 and the lower pressing head 164 towards each other. After pressing, the upper cylinder body 165 pulls the upper pressing head 163 back to the original position, and the lower cylinder body 166 continues to push the lower pressing head 164 along the third direction towards the upper pressing head 163, so as to push the briquette 400 out of the pressing cavity 1621a and achieve demolding.

[0102] Here, the travel of the upper pressing head 163 and the lower pressing head 164 can be detected by optical measurement or mechanical displacement, so as to confirm the size of the briquette 400 in the third direction.

[0103] It can be understood that the shape of the pressing cavity 1621a determines the shape of the briquette 400, and indirectly determines the approximate shape of the source core 101. The shape of the pressing cavity 1621a can be a cube, a cylinder, a prism, etc.

[0104] Exemplarily, the die 162 is divided into two layers of an inner ring 1621 and an outer ring 1622. The inner ring 1621 is formed with the pressing cavity 1621a. The material of the inner ring 1621 can be tungsten alloy. The high hardness of the tungsten alloy can improve the situation that the long-term use of the material causes the cavity wall of the pressing cavity 1621a to be scratched and the die 162 to be scrapped, thereby improving the problem that the die 162 is easily stuck and the briquette 400 cannot be formed. The material of the outer ring 1622 of the die 162 can be alloy steel, which has high tensile strength. The inner ring 1621 and the outer ring 1622 of the die 162 are connected by cold or hot nesting process. The exposed parts of the pressing module 16 are metal parts, and the whole is subjected to rust and corrosion prevention treatment, which can improve the situation that the parts are easily rusted in a radioactive environment and prolong the service life.

[0105] Exemplarily, the upper cylinder body 165 and the lower cylinder body 166 can be an execution unit such as a pneumatic cylinder, an electric cylinder or a hydraulic cylinder, which is not limited herein.

[0106] Exemplarily, the frame body 161 can include support plates 1611, sliding plates 1612 and sliding rods 1613. The three support plates 1611 are sequentially arranged along the third direction, and adjacent two support plates 1611 are connected by a plurality of sliding rods 1613. The sliding plate 1612 is arranged between the adjacent two support plates 1611 and can slide along the third direction with the sliding rod 1613. The two sliding plates 1612 are respectively connected with the upper pressing head 163 and the lower pressing head 164. The upper cylinder body 165 drives one sliding plate 1612 to reciprocate along the third direction through the upper pressing head 163, and the lower cylinder body 166 drives the other sliding plate 1612 to reciprocate along the third direction through the lower pressing head 164. In this way, the sliding rod 1613 can guide the upper pressing head 163 and the lower pressing head 164 through the sliding plate 1612, thereby improving the reliability and stability of the reciprocating movement of the upper pressing head 163 and the lower pressing head 164.

[0107] In an embodiment, the upper cylinder body 165 and the lower cylinder body 166 are electric cylinders. The electric cylinders can improve the service life by using radiation-resistant motors and taking anti-radiation reinforcement measures. For example, a shielding plate can be added to the support plate 1611 and the sliding plate 1612 between the motor and the mold 162 to shield the radiation from the radioactive material in the mold 162.

[0108] It should be noted that the second transfer module 17 can include a third sliding table 171, a fourth sliding table 172 and a fifth sliding table 173. The third sliding table 171 is arranged on the rack 11 and is in sliding cooperation with the rack 11 along the second direction. The fourth sliding table 172 is arranged on the third sliding table 171 and is in sliding cooperation with the third sliding table 171 along the third direction. The fifth sliding table 173 is arranged on the fourth sliding table 172 and is in sliding cooperation with the fourth sliding table 172 along the first direction.

[0109] The number of the fifth sliding table 173 is not limited and can be one or more.

[0110] The plurality in the embodiments of the present application refers to two or more.

[0111] Exemplarily, the preparation device 10 further includes a disc piece 23. The disc piece 23 is used to receive the pressed and formed briquettes 400 and can be placed in the sintering furnace 20 together with the briquettes 400 for high-temperature heating. The material of the disc piece 23 is not limited in particular and can be high-temperature-resistant ceramic or alloy.

[0112] Exemplarily, the second transfer module 17 can comprise a fixed jaw 174 disposed on the fifth sliding table 173, which can be used to take and place the disc piece 23.

[0113] Exemplarily, the second transfer module 17 can comprise a first rotary jaw 175 disposed on the fifth sliding table 173, which can rotate relative to the fifth sliding table 173 and be used to clamp the powder bottle 300 on the first placement table 18 and transfer the powder bottle 300 to the vicinity of the mold 162 of the pressing module 16. Here, the first rotary jaw 175 can directly pour the powder in the powder bottle 300 into the compression cavity 1621a of the mold 162 through rotation, or can transfer the powder in the powder bottle 300 to the compression cavity 1621a of the mold 162 through other mechanisms such as a funnel 251, which is not limited here.

[0114] Further, 10.0 g of aluminum powder or strontium carbonate powder can be weighed by a balance and loaded into the powder bottle 300 to complete the bottle filling of the powder bottle 300.

[0115] Further, the fixed jaw 174 and the first rotary jaw 175 are respectively disposed on two independent fifth sliding tables 173, which can realize independent actions of the fixed jaw 174 and the first rotary jaw 175 and improve the flexibility of the first transfer module 15.

[0116] Exemplarily, please refer to Figure 4 , Figure 6 and Figure 10 , the preparation device 10 further comprises a push rod assembly 22 comprising a push plate 221 and a second moving unit 222, which is movably disposed on the rack 11. The push rod assembly 22 can drive the push plate 221 to push the demolded core block 400 to the disc piece 23 through the second moving unit 222. The disc piece 23 is provided with a plurality of open grooves 23a for positioning the core block 400. After receiving a core block 400, the disc piece 23 moves away from the upper top surface of the mold 162 and rotates to align the empty open groove 23a with the upper top surface of the mold 162, ready for receiving the next core block 400. After continuously pressing, demolding, core block 400 size measurement, core block 400 transfer, preparation and collection of sufficient core blocks 400, the disc piece 23 with the core blocks 400 is grabbed by the second transfer module 17 or the hot cell manipulator, the remote control motor, electric cylinder or hydraulic cylinder opens the furnace door 201 of the sintering furnace 20, and the disc piece 23 is sent into the sintering furnace 20.

[0117] Exemplarily, please refer to Figures 1 to 6The manufacturing device 10 further comprises a second placement table 21, which can be used to place the disc piece 23 taken out from the sintering furnace 20. Specifically, the second transfer module 17 or the hot cell manipulator can take out the disc piece 23 that has completed sintering in the sintering furnace 20 and transfer it to the second placement table 21. The suction cup assembly 153 can suck the source core 101 that has not been measured in size from the disc piece 23 on the second placement table 21 to the measurement table 121, where the size of the source core 101 is measured.

[0118] For example, referring to Figures 1 to 6 The manufacturing device 10 further comprises a third placement table 24, which can be used to place the disc piece 23 that is not filled with the core block 400. The third placement table 24 can rotate to drive the disc piece 23 to rotate, so that the empty opening groove 23a is aligned with the upper top surface of the mold 162, and is ready to receive the next core block 400.

[0119] For example, referring to Figure 4 、 Figure 6 and Figure 17 The manufacturing device 10 further comprises a cleaning module 19, which is used to clean the pressing module 16.

[0120] In this way, the cleaning module 19 can clean the powder particles remaining on the surface of the pressing module 16, which can improve the situation that the pressing cavity 1621a of the mold 162 and the pressing head are easily stuck together after the residual powder on the pressing module 16 is extruded and compacted after multiple uses.

[0121] For example, the cleaning module 19 comprises a first moving unit 191, a rotating mechanism 192 and a brush head 193. The first moving unit 191 is arranged on the rack 11, the rotating mechanism 192 is arranged on the first moving unit 191, the first moving unit 191 can drive the rotating mechanism 192 to move relative to the rack 11, and the rotating mechanism 192 is connected with the brush head 193 and can drive the brush head 193 to rotate. The brush head 193 can extend into the mold 162 of the pressing module 16 to clean the powder particles remaining on the surface of the mold 162.

[0122] For example, the brush head 193 can be a soft brush, which can be made of metal, polymer material or the like, and the hardness of the brush head 193 is lower than that of the material of the mold 162.

[0123] Further, the first moving unit 191 can drive the rotating mechanism 192 to move relative to the rack 11 along a first direction, a second direction and a third direction, so as to improve the flexibility of the cleaning module 19 and facilitate the cleaning module 19 to move the brush head 193 into the pressing cavity 1621a of the mold 162.

[0124] Further, the brush head 193 can be provided with a hollow pipeline, and the powder brushed down can be sucked into the hollow pipeline and collected by a filter. In this way, the residual powder can be collected and transferred away from the pressing module 16, which can improve the situation that the powder scattered after being brushed off from the pressing module 16, and is beneficial to improve the cleanliness of the pressing module 16 and the rack 11, and further improve the cleanliness of the entire preparation device 10.

[0125] For example, referring to Figure 4 , Figure 6 and Figure 12 , the preparation device 10 further comprises a sweeping and knocking down material module 25, which comprises a hopper 251, a sweeping unit 252, a knocking unit 253, and a vibrating unit 254. The powder bottle 300 can be placed on the hopper 251, and the powder bottle 300 can be knocked from above by the knocking unit 253 to speed up the outflow of the powder in the powder bottle 300. At the same time, the vibrating unit 254 can vibrate the hopper 251 to shake off as much powder as possible remaining on the hopper 251 into the die cavity 1621a. The sweeping unit 252 can be wrapped around the upper punch 163 or the lower punch 164 and clean the upper punch 163 or the lower punch 164. The hollow pipeline can also be provided in the sweeping unit 252, and the powder brushed down can be sucked into the hollow pipeline and collected.

[0126] In some embodiments, referring to Figure 5 , Figure 7 and Figure 11 , the welding module 14 comprises a welding station assembly 141 and a welding gun assembly 142. The welding station assembly 141 is provided on the rack 11 and has a welding station 141a. The welding gun assembly 142 is movably provided on the rack 11. The welding gun assembly 142 is configured to weld the assembled first shell 1021 and the first cover 1022 into the first enclosure 102 at the welding station 141a.

[0127] It should be noted that the welding station assembly 141 has the welding station 141a, that is, the position of the welding station assembly 141 determines the position of the welding.

[0128] For example, the position of the welding station assembly 141 is adjustable along the third direction, which can improve the flexibility of the welding station assembly 141.

[0129] The welding gun assembly 142 can realize the welding sealing between the first shell 1021 and the first cover 1022 by girth welding or end welding, and be cooled to room temperature.

[0130] The welding gun assembly 142 can also be configured to weld the assembled second shell 1031 and the second cover 1032 into the second enclosure 103 at the welding station 141a.

[0131] For example, the welding torch assembly 142 can also achieve a weld seal between the second housing 1031 and the second cover 1032 by circumferential welding or end welding.

[0132] For example, the welding torch assembly 142 can perform either argon arc welding or laser welding. Argon arc welding is a welding technique that uses argon gas as a shielding gas, also known as argon gas shielded welding. It involves circulating argon gas around the arc welding area to isolate the weld zone from air and prevent oxidation. Laser welding is a method of welding that uses a focused laser beam as an energy source to bombard the workpiece with the heat generated.

[0133] For example, the welding station assembly 141 includes a first welding station unit 1411 and a second welding station unit 1412 disposed on the frame 11. The first welding station unit 1411 and the second welding station unit 1412 are disposed adjacent to each other. The first welding station unit 1411 is provided with a first groove 1411a, and the second welding station unit 1412 is provided with a second groove 1412a. The first groove 1411a and the second groove 1412a together define a welding station 141a. The first groove 1411a can move with the first welding station unit 1411 relative to the frame 11 in a third direction, and the second groove 1412a can move with the second welding station unit 1412 relative to the frame 11 in a third direction.

[0134] Exemplarily, the welding module 14 further includes a second rotating gripper 143 and an ejector pin unit 144 disposed on the frame 11. The second rotating gripper 143 is disposed on one side of the welding table assembly 141 along the second direction, and the ejector pin unit 144 is disposed on the other side of the welding table assembly 141 along the second direction. The second rotating gripper 143 is used to grip and fix the first housing 1021 or the second housing 1031, and the ejector pin unit 144 is used to press against the first cover 1022 or the second cover 1032 from the other side toward the second rotating gripper 143, preparing for welding of the welding assembly. It is understood that the second rotating gripper 143 can rotate the first housing 1021 or the second housing 1031 at the welding station 141a, thereby facilitating continuous welding of the welding module 14 and improving welding efficiency.

[0135] Exemplarily, in some embodiments, the second rotating gripper 143 is arranged at one end of the first soldering table unit 1411 away from the second soldering table unit 1412, the ejector pin unit 144 is arranged at one end of the second soldering table unit 1412 away from the first soldering table unit 1411, the clamping assembly 152 clamps the first shell 1021 and places it in the first groove 1411a, the suction cup assembly 153 sucks the measured source core 101 and places it in the second groove 1412a, the second rotating gripper 143 clamps the first shell 1021, and the ejector pin unit 144 can eject the source core 101 in the second groove 1412a into the first shell 1021, thereby completing the assembly of the source core 101 and the first shell 1021. That is, the assembly of the source core 101 and the first shell 1021 can be performed on the soldering station 141a instead of the first assembly station 13a.

[0136] Similarly, after the assembly of the source core 101 and the first shell 1021 is completed, the suction cup assembly 153 can directly suck the first cover 1022 and place it in the second groove 1412a, and the ejector pin unit 144 can drive the first cover 1022 to abut and assemble with the first shell 1021, or the suction cup assembly 153 can directly abut and assemble the first cover 1022 with the first shell 1021. After the abutment and assembly of the first cover 1022 by the ejector pin unit 144 is completed, the first cover 1022 can be directly welded by the welding module 14, thereby further improving the efficiency of assembly and welding.

[0137] The welding gun assembly 142 is movably arranged on the rack 11, that is, the welding gun assembly 142 can move and adjust the position on the rack 11, which is beneficial to improve the flexibility of the welding gun assembly 142 and facilitate the welding gun assembly 142 to avoid other components.

[0138] Exemplarily, referring to Figure 6 and Figure 11 , the welding gun assembly 142 comprises a sixth sliding table 1421, a seventh sliding table 1422, an eighth sliding table 1423, and a welding head 1424. The sixth sliding table 1421 is slidably arranged with the rack 11 along a second direction, the seventh sliding table 1422 is arranged on the sixth sliding table 1421 and can slide relative to the sixth sliding table 1421 along a third direction, the eighth sliding table 1423 is arranged on the seventh sliding table 1422 and can slide relative to the seventh sliding table 1422 along a first direction. The welding head 1424 is rotationally arranged with the eighth sliding table 1423. In this way, the flexibility of the welding gun assembly 142 can be improved, the orientation of the welding head 1424 can be flexibly adjusted, and the welding gun assembly 142 can be driven to avoid other components when the welding assembly is not working.

[0139] Exemplarily, referring to Figure 3 and Figure 13The rack 11 comprises a first sub-rack 111, a second sub-rack 112 and a third sub-rack 113 connected in sequence along the second direction. The first sub-rack 111 is used to arrange components required in the post-sintering process, such as the first transfer module 15, the measuring module 12, the assembly table 13 and the welding module 14. The second sub-rack 112 is used to arrange the sintering furnace 20. The third sub-rack 113 is used to arrange components required in the pre-sintering process, such as the second transfer module 17, the pressing module 16, the cleaning module 19 and the first placement table 18. In this way, the post-sintering process and the pre-sintering process can be separated, which is conducive to reducing the interference between components in the processes, improving the compact structure, and improving the overall efficiency of preparation. In addition, the rack 11 can be disassembled, facilitating transportation, quick disassembly, repair and assembly, reducing maintenance and repair time, and improving maintainability, Exemplarily, the preparation device 10 provided by the embodiment of the present application can be equipped with a remote control console for remote automatic control. The remote control console is arranged outside the hot cell and connected to the equipment in the hot cell through a wall passage of the hot cell.

[0140] Exemplarily, the welding module 14, the cleaning module 19, the first transfer module 15 and the second transfer module 17 are each realized by a PLC-controlled movable mechanism as a driving mechanism to realize the relative movement between each module and the rack 11.

[0141] In actual application, the preparation device 10 can be installed into the hot cell as a whole. In consideration of the stability of the strong radiation field transmission or electronic components, part of the PLC-controlled movable mechanism can be removed, and a hot cell manipulator is used to complete material transfer, thereby improving the overall stability.

[0142] Exemplarily, the second transfer module 17 is configured to be able to slide from the first sub-rack 111 to the second sub-rack 112 and the third sub-rack 113 along the second direction, thereby playing a role in transferring materials between the first sub-rack 111, the second sub-rack 112 and the third sub-rack 113.

[0143] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
