[0020] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The descriptions in this section are merely illustrative and explanatory, and should not be construed as limiting the scope of protection of this application. Specifically, the described embodiments are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the scope of protection of this invention.

[0021] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0022] It should be noted that a nuclear fuel assembly consists of a certain number of fuel rods arranged at certain intervals and fixed into a bundle. It mainly consists of an upper tube seat, a lower tube seat, a grid, control rod guide tubes, and fuel rods. The grid is mainly used to load and position the fuel rods and is composed of multiple first and second strips spliced ​​together. The strips have a plate-like structure with multiple parallel openings, the openings on the first and second strips facing opposite directions. In existing technology, multiple strips are spliced ​​into a grid manually using a limiting mold. During operation, the operator first clamps multiple first strips onto the mold in the same direction, with all openings facing upwards. Then, multiple second strips are spliced ​​onto the first strips, with the openings of the second strips facing downwards, and inserted into the openings of the first strips. This step is repeated until the grid is finally formed.

[0023] Example 1 As mentioned in the background section, to address the problems existing in the prior art, this embodiment provides an automated assembly system for nuclear fuel grids based on an adaptive clamping mechanism, used to splice the first strip 101 and the second strip into a grid along two mutually perpendicular directions. The assembly system includes: Base 1; A clamping mechanism is provided, in which multiple clamping mechanisms are equally spaced on the base 1 along a first direction. Each clamping mechanism includes a first partition 2 and a second partition 3, and there is a first gap between the first partition 2 and the second partition 3 in each group. The first partition 2 is fixed to the base 1, and multiple insertion slots are equally spaced on the first partition 2 and the second partition 3 along a second direction. The insertion slots of the first partition 2 and the second partition 3 correspond one-to-one along the first direction. The second direction is perpendicular to the first direction. Two drive components 4 are disposed on the base 1 along the second direction. The drive ends of the drive components 4 are respectively fixed to each of the second partitions 3, and are used to drive the second partitions 3 to move along the first direction to adjust the size of the first gap.

[0024] like Figure 1-4 As shown, the first direction is the vertical direction, and the second direction is the horizontal direction. The base 1 is the load-bearing structure of the assembly system. Multiple first partitions 2 are fixed at equal intervals along the first direction on the base 1. Multiple second partitions 3 are also set at equal intervals along the first direction and correspond one-to-one with the first partitions 2. A first gap is formed between the corresponding first partitions 2 and second partitions 3. The first gap is used to set the first strip 101. The first partitions 2 and second partitions 3 are both approximately plate-shaped structures and extend along the second direction. Multiple upward-facing insertion slots are opened along their length directions. Each insertion slot corresponds along the first direction and is used to set the second strip. The driving component 4 can be a cylinder in the prior art. Two cylinders are fixed on the base 1 along the second direction. The piston rod of the cylinder extends along the first direction and is fixed to one end of the multiple second partitions 3 along the second direction, thereby driving the multiple second partitions 3 to move synchronously along the first direction to achieve the effect of adjusting the size of the first gap. Furthermore, the first partitions 2 and second partitions 3 are both precision-machined, possessing both flatness and strength, and can withstand assembly pressure and ensure the stability of the strip during assembly.

[0025] By setting a first partition 2 and a second partition 3, a first gap is formed between the first partition 2 and the second partition 3 in each group. At the same time, the driving component 4 drives each second partition 3 to move synchronously, and together with the corresponding first partition 2, clamps the first strip 101, so that the first strip 101 is automatically aligned. After the second strip is inserted, it is clamped again to ensure the overall accuracy of the grid after splicing. Compared with the traditional manual splicing method, it avoids problems such as strip insertion failure and misalignment caused by human factors, saves manpower and ensures the stability of the grid after splicing.

[0026] In a preferred embodiment, the base 1 includes: The support platform is equipped with a first partition 2; The four columns 11 are respectively located at the four corners of the support platform, and the drive components 4 are provided on the columns 11.

[0027] like Figure 1-3 As shown, the bearing platform is approximately a cuboid platform. The bearing platform is usually made of rigid material and is used to support the clamping mechanism. The columns 11 are fixed at the four corners of the bearing platform. The driving component 4 is fixed on the column 11. The driving end of the driving component 4 passes through the column 11 along the first direction and extends between the two columns 11 to be fixed with each of the second partitions 3.

[0028] In a preferred embodiment, a guiding device is further included, the guiding device comprising: Guide posts 5, two guide posts 5 are distributed on the base 1 along the second direction, and the guide posts 5 extend along the first direction; Guide sleeve 6 is slidably sleeved on guide post 5, and guide sleeve 6 is fixed to the driving end of driving component 4.

[0029] like Figure 1-3 As shown, the guide post 5 is approximately cylindrical in structure. Two guide posts 5 are distributed along the second direction, and the two ends of the guide post 5 are respectively fixed to two columns 11 corresponding to the first direction. The guide sleeve 6 is slidably sleeved on the guide post 5 and located between the two columns 11. The bottom of the guide sleeve 6 is fixed to the driving end of the driving component 4. By setting the mutually cooperating guide posts 5 and guide sleeve 6, the driving end of the driving component 4 can move smoothly and accurately, minimizing locking failures caused by friction or jamming, while ensuring the movement accuracy of the second partition 3 under the drive of the driving component 4, and ensuring the accuracy of strip insertion.

[0030] In a preferred embodiment, the guide sleeve 6 is provided with a plurality of grooves 61 at equal intervals along the first direction, and the grooves 61 correspond one-to-one with the first gap along the second direction.

[0031] like Figure 1 As shown, the guide sleeve 6 is provided with a plurality of grooves 61 at equal intervals along the first direction. The openings of the grooves 61 are set facing upward and correspond one-to-one with the first gap. The grooves 61 are used to accommodate the end of the first strip 101 when the first strip 101 is inserted, so as to avoid interference between the first partition 2 and the guide sleeve 6.

[0032] Furthermore, the guide sleeve 6 is provided with positioning pins 7, and multiple positioning pins 7 are sequentially arranged in each groove 61; For details, please refer to Figure 3 and Figure 4 Multiple positioning pins 7 are fixed in each groove 61. When the first strip 101 is inserted into the first gap, the end of the first strip 101 is located in the groove 61 and corresponds to the positioning pin 7. By setting the positioning pin 7, the installation positioning of the first strip 101 during insertion can be assisted, and the installation deviation of the first strip 101 can be reduced.

[0033] Furthermore, multiple clamping mechanisms are provided with positioning plates on both sides along the first direction. Multiple positioning grooves are provided at equal intervals along the second direction on the positioning plates. The positioning grooves are arranged in accordance with the insertion grooves along the first direction. The positioning grooves are used to accommodate the end of the second strip and provide auxiliary positioning function to ensure that the second strip is inserted into place.

[0034] In a preferred embodiment, an elastic element 8 is sleeved on the guide post 5, and the elastic element 8 is located between the end of the column 11 and the guide sleeve 6 away from the drive element 4.

[0035] like Figure 3 As shown, the elastic element 8 is a spring in the prior art. The elastic element 8 is sleeved on the guide post 5. The two ends of the elastic element 8 abut against the column 11 and the guide sleeve 6 respectively. The elastic element 8 is used to provide a buffering effect when the driving element 4 drives the second partition 3 to move. When the grid splicing is completed and the driving element 4 stops, the elastic element 8 can assist the second partition 3 to reset through its own elastic force, thereby facilitating the separation of the grid from the assembly system.

[0036] In a preferred embodiment, the device further includes a demolding mechanism 9, which includes a first part, a second part, and a third part that are integrally connected. The first part can be sleeved on multiple clamping mechanisms in a vertical direction, and the second part and the third part are respectively located at both ends of the first part in a first direction.

[0037] like Figure 1 As shown, the demolding mechanism 9 is approximately a rectangular frame structure, including an integrally connected first part, second part, and third part. The first part can be sleeved on the outer periphery of multiple clamping mechanisms in the vertical direction, located on the bearing platform, and the height of the first part in the vertical direction is lower than the insertion slot. The second part and the third part are located at both ends of the first part in the first direction, which are used to provide gripping force points when the first part is moved. When the strips are inserted, the ends of the first strip 101 and the second strip are both placed on the first part. The first part is moved upward in the vertical direction by the second part and the third part, which can separate the spliced ​​grid from the assembly system, thereby completing the demolding work.

[0038] In a preferred embodiment, each group of first partition 2 and second partition 3 is provided with an arc-shaped groove 21 on the side that is close to each other, and the arc-shaped groove 21 is adapted to the outer surface contour of the first strip 101.

[0039] like Figure 4As shown, the arc-shaped grooves 21 are located on the side of the first partition 2 and the second partition 3 of each group that are close to each other. The multiple arc-shaped grooves 21 are evenly distributed along the length direction of the first partition 2 / second partition 3. The arc-shaped grooves 21 are adapted to the outer surface contour of the first strip 101, ensuring that the first strip 101 can be evenly stressed when the first partition 2 and the second partition 3 clamp the first strip 101. At the same time, the arc-shaped grooves 21 can effectively prevent the first strip 101 from deforming, thus improving the assembly quality.

[0040] In a preferred embodiment, the clamping mechanism is provided with a detection element, which is electrically connected to a controller. The detection element is used to detect the pressure at the first gap and generate a first detection signal. The controller is used to control the drive element 4 according to the first detection signal.

[0041] The detection component can be a pressure sensor from the prior art. The pressure sensor is set on the clamping mechanism and electrically connected to the controller. The pressure sensor is used to detect the pressure on the first strip 101 in the first direction when the drive 4 is working, and feeds back the first detection signal to the controller. The controller controls the drive 4 according to the first signal, thereby forming a closed-loop control to ensure that the first partition 2 and the second partition 3 can lock the first strip 101.

[0042] Furthermore, both the first partition 2 and the second partition 3 are equipped with standardized interfaces. Multiple first partitions 2 are detachably connected to the base 1, and multiple second partitions 3 are detachably connected to the drive end of the drive component 4. The assembly system is also equipped with a partition library containing different models of first partitions 2 and second partitions 3. When a change of model is required, a gantry robot can be used to grab the corresponding model of first partition 2 and second partition 3 from the partition library to replace the existing partitions on the assembly system, thereby realizing the modular design of the assembly system.

[0043] Example 2 Please refer to Figure 5 This embodiment provides a flowchart illustrating an automated assembly method for a nuclear fuel grid based on an adaptive clamping mechanism. The method employs the automated assembly system for a nuclear fuel grid based on an adaptive clamping mechanism as described in Embodiment 1. The assembly method includes: S1. Insert multiple first strips 101 sequentially into the first gap along the first direction, so that the opening of the first strip 101 corresponds to the insertion groove along the first direction; Multiple first strips 101 are sequentially inserted into the first gap, so that the two ends of the first strip 101 are respectively located in the grooves 61 of the guide sleeves 6 on both sides and aligned with the positioning pins 7. At the same time, the opening of the first strip 101 corresponds to the insertion groove along the first direction. Furthermore, in order to improve the automation level of grid splicing, a scaffolding robot can be used to grab the strips for splicing. The scaffolding robot can cooperate with the positioning pins 7 in the grooves 61 to ensure that the first strip 101 is accurately placed in the first gap.

[0044] S2. Drive each second partition 3 to move along the first direction by the driving component 4 until the pressure on the first belt 101 in the first direction reaches the first set pressure. After the first strip 101 is inserted, the controller adjusts the output pressure of the drive unit 4 to the first set pressure and starts the drive unit 4. The drive unit 4 drives each second partition 3 to move along the guide post 5 and approach the corresponding first partition 2. Then, the first partition 2 and the second partition 3 work together to clamp the first strip 101. During this process, the movement speed of the drive end of the drive unit 4 can be precisely controlled by controlling the airflow to avoid damage to the first strip 101. The detection element in the clamping mechanism detects the pressure on the first strip 101 when it is locked and feeds the data back to the controller to ensure reliable locking. The clamping mechanism clamps the first strip 101 to eliminate the cumulative error after the first strip 101 is assembled, ensuring the flatness and shape stability of the first strip 101.

[0045] S3. Insert multiple second strips into the insertion slots in sequence along the second direction, so that the opening of the second strip corresponds to the opening of the first strip 101 and they are spliced ​​together to form a grid. Make the opening of the second strip correspond one-to-one with the opening of the first strip 101, and insert multiple second strips into the insertion slots in sequence along the second direction. The two ends of the second strips are respectively located in the positioning slots of the positioning plates on both sides. Furthermore, this process can also be completed by a truss robot. The gripping device of the truss robot can be made of flexible material to prevent the strips from deforming or being damaged on the surface during gripping.

[0046] S4. Drive each second partition 3 again along the first direction by the drive component 4 until the pressure on the first belt 101 in the first direction reaches the second set pressure, and the second set pressure is greater than the first set pressure. After the second strip is inserted, the controller adjusts the output pressure of the drive unit 4 to the second set pressure. The drive unit 4 drives each second partition 3 to continue moving along the guide post 5, approaching the corresponding first partition 2. The first partition 2 and the second partition 3 further clamp the first strip 101. During this process, the detection unit continuously detects the pressure on the first strip 101 to accurately control the locking force, ensuring that the fit gap between all strips fully meets the design requirements, while avoiding overpressure that could cause strip deformation, thus ensuring the stable formation of the grid main structure.

[0047] S5, Stop drive unit 4, Separation grid and assembly system; The controller stops the drive unit 4, and the mold ejection mechanism 9 moves the entire grid frame upward in the vertical direction, separating it from the assembly system and placing the grid frame in the finished product area. At this point, the grid frame assembly is complete.
