For the purpose of clarity and a concise description, all the features of the practical embodiments are not described in the specification.

In addition, it should be appreciated that, although the development work can be very complex and time-consuming, it is only a routine task for those skilled in the art who benefit from the content of the present application.

[0026] It should also be noted herein that, in order to avoid obscuring the present application with unnecessary details, only the device structures and / or processing steps closely related to the scheme according to the present application are shown in the accompanying drawings, and other details not closely related to the present application are omitted.

[0027] The following disclosure provides a plurality of different embodiments or examples for implementing the present application. In order to simplify the disclosure of the present application, the components and methods of a specific example are described below. Of course, they are only examples and the purpose is not to limit the present application. In the description of the embodiments of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] When a retired reactor is cut into a plurality of cut blocks, if the shapes and weights of the plurality of cut blocks are relatively close, the loading space and loading time can be saved when the cut blocks are loaded into a loading container. However, the structure of the reactor is relatively complex, and the shape difference at different positions is large, so it is very difficult to cut the reactor into cut blocks that meet the requirements.

[0029] In order to solve the above problems, referring to Figure 1 The embodiments of the present application provide a cutting method of a reactor component, comprising the following S1 step to S5 step:

[0030] S1: Obtain the geometric parameters and physical property parameters of the reactor.

[0031] S2: Determine a digital model of the reactor according to the geometric parameters and physical property parameters of the reactor.

[0032] S3: determining, according to the digital model, a geometric parameter of each cut piece after the reactor is cut.

[0033] S4: cutting the reactor according to the geometric parameter of each cut piece, to obtain each cut piece after cutting.

[0034] S5: verifying the geometric parameter of each cut piece, to determine that each cut piece meets the predetermined requirement.

[0035] The cutting method of the reactor component provided by the embodiment of the application can ensure that the weight and shape of each cut piece after cutting meet the requirements, so that the cut pieces with the weight and shape meeting the requirements are obtained in the actual cutting process, thereby facilitating subsequent loading work.

[0036] In some embodiments, in the step S3, the following steps S31 to S33 are further included:

[0037] S31: determining, according to the digital model, a relationship between the geometric parameter of each cut piece and the total number of cut pieces.

[0038] S32: determining the total number of cut pieces according to the value range of the geometric parameter of each cut piece and the relationship between the geometric parameter of each cut piece and the total number of cut pieces.

[0039] S33: determining the geometric parameter of each cut piece according to the total number of cut pieces.

[0040] The value range of the geometric parameter of each cut piece is limited by relevant parameters of a specific device. For example, when the number of cut pieces is too small, the weight of a single cut piece is too heavy, so that the cut piece cannot be lifted by a lifting device. Therefore, the weight of the cut piece, as the geometric parameter, is limited by the maximum lifting weight of the lifting device. The geometric parameter of each cut piece determined according to the above method can meet the parameter requirement of the specific device, so that the cutting work can be completed smoothly.

[0041] In some embodiments, in the step S32, the total number of cut pieces satisfies the following expression:

[0042]

[0043] In the expression, X is the total number of cut pieces; g1(X) is the chord length corresponding to the outer arc length of a single cut piece; b1 is the bottom side length of a loading container used for loading the cut pieces; g2(X) is the weight of a single cut piece; b2 is the maximum lifting weight of a lifting device used for lifting the cut pieces; T(X) is the total cutting time; Z(X) is the space utilization rate, and s.t. represents a linear constraint.

[0044] Through the above expression, the total cutting time, the space utilization, the side length of the loaded container, and the maximum lifting weight of the hoisting device can be multi-objectively optimized, so as to calculate the accurate total number of cuttings.

[0045] In some embodiments, in the step S31, the relationship between the chord length corresponding to the outer arc length of a single cutting and the total number of cuttings satisfies the following expression:

[0046]

[0047] In the formula, r is the radius of the outer arc of the cutting.

[0048] According to the above expression, the relationship between the chord length corresponding to the outer arc length of a single cutting and the total number of cuttings can be more accurately obtained, so as to more accurately determine the range of the total number of cuttings.

[0049] In some embodiments, in the step S31, the relationship between the weight of a single cutting and the total number of cuttings satisfies the following expression:

[0050]

[0051] In the formula, M is the mass of the structure to be cut.

[0052] According to the above expression, the relationship between the weight of a single cutting and the total number of cuttings can be more accurately obtained, so as to more accurately determine the range of the total number of cuttings.

[0053] In some embodiments, in the step S31, the relationship between the total cutting time and the total number of cuttings satisfies the following expression:

[0054]

[0055] In the formula, r1 and r2 are the radii of the outer arc and the inner arc to be cut respectively, d is the sum of the radial and axial movement distances of the cutting device, and v is the cutting speed of the cutting device.

[0056] According to the above expression, the relationship between the total cutting time and the total number of cuttings can be more accurately obtained, so as to more accurately determine the range of the total number of cuttings.

[0057] In some embodiments, in the step S32, the space utilization of the cuttings in the loading container is converted into the plane utilization of the cuttings in a two-dimensional plane.

[0058] By converting the space utilization of the cuttings in the loading container into the plane utilization of the cuttings in a two-dimensional plane, one dimension of variable can be reduced, and the calculation process can be simplified.

[0059] In some embodiments, the cutting method further comprises the following steps: replacing the cutting block with a polygon; generating a layout area, generating a critical polygon and an inner critical polygon according to the polygon replacing the cutting block; determining the position of the reference polygon in the layout area; determining the optimal layout position of the next polygon according to the layout position of the reference polygon; determining the optimal layout position of each polygon in turn, and obtaining the plane utilization of the cutting block in the two-dimensional plane according to the optimal layout position.

[0060] Through the above method, the optimal placement mode corresponding to different block numbers and the space utilization under the placement mode can be determined. By comparing the space utilization corresponding to different block numbers, the range of the total number of cutting blocks can be more accurately determined.

[0061] In some embodiments, in the S5 step, verifying the geometric parameters of each cutting block comprises: verifying the feasibility of cutting; verifying whether the cutting device will have spatial interference with the digital model of the reactor.

[0062] In the cutting process, in addition to considering the properties of the reactor, the relationship between the reactor and the cutting device also needs to be considered. For example, when the gap between the reactor components is not sufficient for the cutting device, such as a mechanical hand, to pass through, it means that the cutting device has spatial interference, although the total number of cutting blocks meets the requirements, but this cutting mode cannot be implemented. By verifying the feasibility of cutting, the cutting scheme that cannot be implemented can be modified in time to ensure the smooth completion of the cutting operation.

[0063] Figure 2 An effect diagram for verifying whether the cutting device will have spatial interference with the reactor is shown in one embodiment of the present application. As can be seen from the diagram, when the cutting device 10 cuts one of the reactor components 30, the cutting device 10 "passes through" another reactor component 30, which means that in the actual cutting process, the cutting device 10 will be blocked by another reactor component 30 when cutting one of the reactor components 30, and cannot be implemented. Therefore, in the actual cutting, this scheme is not used to cut the reactor.

[0064] In some embodiments, verifying the feasibility of cutting comprises: simulating the cutting laser; determining whether the simulated cutting laser can completely cut through the digital model of the reactor.

[0065] The length of the cutting laser is limited. If the thickness of the reactor in a certain direction is thick, the cutting laser cannot cut through the reactor, thereby causing the cutting to fail. By simulating the cutting laser and determining whether the cutting laser can completely cut through the digital model of the reactor, the above situation can be avoided, and the cutting operation can be completed smoothly.

[0066] Figure 3a andFigure 3b The effect schematic diagram of verifying the feasibility of cutting in two different embodiments is shown, wherein, in Figure 3a , the length of the cutting laser 20 is shorter than the thickness of the reactor assembly 30, so it is judged that the simulated cutting laser cannot cut through the reactor, and the reactor is not cut by this scheme in actual cutting. In Figure 3b , the length of the cutting laser 20 is longer than the thickness of the reactor assembly 30, so it is judged that the simulated cutting laser can cut through the reactor, and the reactor can be cut by this scheme in actual cutting.

[0067] In some embodiments, in the S1 step, the following steps are included: a plurality of reference devices are arranged inside and outside the reactor, a coordinate system about the reactor is established according to the positions of the reference devices; a plurality of scanning points are arranged inside the reactor, the coordinates of the scanning points are recorded, and the reactor is scanned at the scanning points, the photos obtained by scanning are converted into point cloud data, and the geometric parameters and physical property parameters of the reactor are obtained according to the point cloud data.

[0068] In some embodiments, in the S2 step, the following steps are included: the point cloud data is imported into modeling software, the modeling software is used to remove the contents in the point cloud data that are not the reactor, the processed point cloud data is spliced and colored according to the positions of the reference devices, and the spliced and colored point cloud data is converted into a digital model of the reactor.

[0069] As shown in Figure 4 , in some embodiments, the cut block is replaced by a polygon, specifically including: for the cut block 100 with a circular arc, a polygon 200 composed of the circumscribed polygon and the inscribed polygon of the circular arc is used to replace the cut block, and the polygon 200 composed of the two satisfies two conditions, one is to completely cover the cut block, and the other is to have the minimum area. Using the polygon 200 to replace the cut block 100 can simplify the calculation when determining the layout position of the cut block later.

[0070] As shown in Figure 5 , in some embodiments, according to the polygon 200 replacing the cut block, a critical polygon 300 is generated, specifically including: the polygon is numbered, for example, A, B, C, and so on, for two polygons A and C, a reference point is determined on the polygon C under the condition that the polygon A and the polygon C are in contact, the polygon C returns to the initial position after rotating around the polygon A for one turn, and the polygon C does not rotate during the movement, and the movement trajectory of the reference point is the critical polygon NFP AC . By establishing the critical polygon 300, the subsequent processing process can be simplified.

[0071] As shown in Figure 6As shown, in some embodiments, an inner critical polygon 400 is generated based on the polygon 200 that replaces the cut-out pieces. Specifically, this includes: establishing a layout region 500 to simulate the bottom of the loading container. The layout region 500 can be, for example, an inscribed decagon of a circular loading container. While polygon C remains in contact with the layout region 500 without intersecting, a reference point is determined on polygon C. Polygon C then returns to its initial position after one revolution around the layout region 500. During this movement, polygon C does not rotate. The trajectory of the reference point is the inner critical polygon INFP. C By establishing an inner critical polygon 400, it can be ensured that when polygon C moves on or inside the inner critical polygon, it will not exceed the range of the nesting area 500.

[0072] In some embodiments, determining the position of a reference polygon in the layout area 500 specifically includes: generating the layout area 500, first determining the position of the first polygon A in the layout area 500, and then determining the position of the second polygon B based on the critical polygon between polygon A and polygon B, wherein polygon A and polygon B are the reference polygons.

[0073] like Figure 7 and Figure 8 As shown, in some embodiments, the optimal layout position of the next polygon is determined based on the layout position of the reference polygon, specifically including: based on the critical polygon NFP between polygon C and polygon A. AC The critical polygon NFP between polygon C and polygon B BC And the inner critical polygon INFP between polygon C and the nesting area 500. C The proposed nesting position for polygon C is determined to be 600. Here, the proposed nesting position 600 is the critical polygon NFP. AC Critical polygon NFP BC and the inner critical polygon INFP C All vertices and their intersections.

[0074] Furthermore, based on the determined proposed layout position 600, the possible layout position 700 of polygon C is determined. Here, the possible layout position 700 is the inner critical polygon INFP within the proposed layout position 600. C Above, and located in the critical polygon NFP AC Critical polygon NFP BC Points other than those mentioned above.

[0075] like Figure 9a to Figure 9cAs shown, after the polygon C is arranged in one of the available nesting positions, the contour area S1, the envelope rectangle area S2 and the overlapping area S3 of all the polygons are obtained, wherein the contour area S1 is the area of the polygon formed by the contour line of all the polygons and the board contour, the envelope rectangle area S2 is the area of the smallest rectangle capable of covering all the polygons, and the overlapping area S3 is the overlapping area of the smallest rectangle capable of covering the current nesting polygon and the smallest rectangle capable of covering the adjacent polygon. The optimal nesting position of the polygon C is determined according to the following order: first, compare the contour area S1 of the polygon C arranged in different available nesting positions, when there is only one minimum value of S1, the position of the value is the optimal nesting position of the polygon C; when there are multiple positions that make S1 reach the minimum value, compare the envelope rectangle area S2 of the polygon C in these positions, when there is only one minimum value of S2, the position of the value is the optimal nesting position of the polygon C; when there are multiple positions that make S2 reach the minimum value, compare the overlapping area S3 of the polygon C in these positions, and the position of the maximum value of S3 is the optimal nesting position of the polygon C. In some embodiments, the polygon C can be arranged only at the vertices of the available nesting positions to reduce the amount of calculation.

[0076] According to the above steps, the optimal nesting position of each polygon is determined in turn, and when the optimal nesting position is determined each time, all the polygons whose positions have been determined need to be considered. When there is no nesting point for a certain polygon, the above steps are terminated, and the nesting diagram arranged according to the nesting method is output, Figure 10 FIG. 1 is a schematic diagram of the nesting diagram output by an embodiment of the present application, wherein the ratio of the sum of the areas of the polygons 200 to the total area of the nesting area 500 is the planar utilization rate of the cutting block in the two-dimensional plane.

[0077] In the above steps, the positions of the first polygon A and the second polygon B have a greater impact on the planar utilization rate of the cutting block in the two-dimensional plane, and based on the above reasons, in some embodiments, a plurality of nesting areas 500 can be generated, the position of the first polygon A in each nesting area 500 is randomly generated, the position of the second polygon B is randomly generated based on the critical polygon, and more nesting areas 500 are generated through operations such as crossover and mutation in the genetic algorithm. The planar utilization rate of each nesting area 500 is determined as described above, the planar utilization rates of the plurality of nesting areas 500 are taken as the fitness function, and the maximum value of the fitness function is output as the maximum planar utilization rate Z of the total number of cutting blocks when the maximum value is greater than or equal to the predetermined utilization rate. max(X) When the maximum value is less than the predetermined utilization rate, the existing layout area 500 is continuously operated to generate more layout areas 500 by crossover, mutation, etc., and the maximum value of the fitness function is recalculated. Each time a set of layout areas 500 is generated and the maximum value of the fitness function is calculated, it is called an iteration, and when the maximum value is greater than or equal to the predetermined utilization rate, or the number of iterations reaches the predetermined number of iterations, the maximum value of the fitness function under the condition is output as the maximum plane utilization rate Z of the total number of cuttings max (X).

[0078] Through the above steps, the best layout mode can be found from a plurality of layout modes, so that the total number of cuttings can be more accurately determined.

[0079] In some embodiments, in the S32 step, the method further comprises: generating a curve graph of the maximum plane utilization rate of the cuttings and the total cutting time and the total number of cuttings, and determining the total number of cuttings according to the curve graph and other constraint conditions.

[0080] As can be easily understood, when the total number of cuttings reaches a certain value, the plane utilization rate of the cuttings will not change substantially even if the total number of cuttings is increased, but the total cutting time will further increase with the increase of the total number of cuttings. By generating the curve graph, the best total number of cuttings can be obtained at a glance.

[0081] Referring to Figure 11 , Figure 11 is a curve graph of the maximum plane utilization rate of the cuttings and the total cutting time and the total number of cuttings generated by an embodiment of the present application. The curve L1 in the graph represents the total cutting time, and the curve L2 represents the plane utilization rate of the cuttings. As can be seen, when the total number of cuttings is 10, the plane utilization rate of the cuttings reaches the maximum of 76%, and with the further increase of the total number of cuttings, the plane utilization rate of the cuttings also basically does not change. However, the total cutting time continues to increase from 8.8 minutes when the total number of cuttings is 10 to 10.8 minutes when the total number of cuttings is 14. Through the above content, it can be obtained that when the remaining constraint conditions are met, 10 is the best total number of cuttings. However, when the other constraint conditions are not met, the best total number of cuttings needs to be determined in combination with the other constraint conditions. For example, in the above embodiment, if the lifting weight of the lifting device requires that the total number of cuttings be greater than or equal to 12, then 12 is the best total number of cuttings.

[0082] The cutting method of the reactor component provided by the present application will be described below in combination with specific embodiments.

[0083] A plurality of reference devices are arranged inside and outside the reactor, and a coordinate system about the reactor is established according to the positions of the reference devices; a plurality of scanning points are arranged inside the reactor, the coordinates of the scanning points are recorded, and the reactor is scanned at the scanning points, the photos obtained by scanning are converted into point cloud data, and the geometric parameters and physical property parameters of the reactor are obtained according to the point cloud data.

[0084] The point cloud data is imported into the modeling software, the content in the point cloud data which is not the reactor is removed using the modeling software, the processed point cloud data is spliced and colored according to the position of the reference device, and the spliced and colored point cloud data is converted into a digital model of the reactor. According to the digital model, the chord length corresponding to the outer arc length of the cut block, the weight of a single cut block, the space utilization rate of the cut block and the total cutting time are determined, and the total number of cut blocks is determined according to the above parameters. According to the total number of cut blocks, the geometric parameters of each cut block are determined. According to the geometric parameters of each cut block, the reactor is cut to obtain each cut block after cutting. The geometric parameters of each cut block are verified, whether the simulated laser can cut through the digital model of the reactor is verified, and whether the cutting device will have spatial interference with the digital model of the reactor is verified.

[0085] In the determination of the space utilization rate of the cut block, the cut block is replaced by a polygon, and according to the polygon replacing the cut block, a critical polygon and an inner critical polygon are generated, a plurality of layout areas are generated, the layout position of the reference polygon is determined in each layout area, and the optimal layout position of the next polygon is determined according to the layout position of the reference polygon. The optimal layout position of each polygon is determined in turn until there is no layout point in the new polygon, and the layout diagram corresponding to the layout position and the plane utilization rate are output. The maximum plane utilization rate is obtained by processing the plurality of layout areas through a genetic algorithm, and is taken as the space utilization rate under the total number of cut blocks.

[0086] After obtaining the space utilization rate under different total numbers of cut blocks, a curve graph of the maximum plane utilization rate and the total cutting time of the cut block and the total number of cut blocks is generated, and the total number of cut blocks is determined according to the curve graph combined with other constraint conditions.

[0087] For the embodiments of the present application, it should also be noted that the embodiments and features in the embodiments of the present application can be combined with each other to obtain new embodiments without conflict.

[0088] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and the protection scope of the present application should be subject to the protection scope of the claims.
