Description

Technical Field

[0001] This application relates to the field of 3D printing technology, and in particular to a method, apparatus, equipment and medium for assembling composite structures. Background Technology

[0002] Composite material 3D printing technology, with its additive manufacturing characteristics of "points, lines, surfaces, and volumes," enables high-degree-of-freedom forming of complex components' materials and structures. This facilitates the manufacturing of functional composites with multiple material properties and innovative structures, finding numerous applications in the aerospace industry. In practical applications, different parts of a single part often have different usage requirements, necessitating the setting of different printing parameters for each part. To address this, many 3D printing slicing software programs have developed corresponding slicing functions, allowing for the setting of individual process parameters for different models when multiple models are simultaneously imported into the slicing software.

[0003] Cura is a commonly used open-source slicing software for composite material 3D printing. After importing the sub-models of multi-performance composite structural parts into Cura, their original coordinates are completely lost. Therefore, the sub-models are not placed according to their relative positions in the 3D software, but are arbitrarily placed in Cura based on the dimensions of each sub-model. The placement position and angle are different. If each sub-model is a standard cube or cuboid, it can be accurately reassembled by manually moving and rotating them. Otherwise, the existing method cannot guarantee the assembly accuracy, and the deviation of the assembled model is quite arbitrary. The assembly accuracy is related to the operator's personal skills, which makes it difficult to achieve accurate assembly of the sub-models of multi-performance composite structures in the slicing software, affecting work efficiency.

Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0022] Example 1 Reference Figures 1-6 This embodiment provides a composite structure assembly method, including the following steps: Step S10: Obtain the multi-layer reference planes for 3D printing the target workpiece model; wherein, the target workpiece model includes multiple sub-models assembled sequentially from bottom to top, and each sub-model has a reference plane corresponding to a height position; Step S20: Construct multiple reference bodies on each reference plane; Step S30: Combine each sub-model with multiple reference bodies of corresponding height to generate multiple process models; Step S40: Import multiple process models into the slicing software, and obtain the height setting parameters of multiple process models from bottom to top in order to complete the assembly.

[0023] Because the combined model of the various sub-models deviates somewhat from the original overall workpiece model, the printed workpiece will have a certain deviation in shape, making it impossible to guarantee part quality. Therefore, to achieve high-quality, high-performance 3D printing of multi-functional composite structures, the following two conditions must be met: first, the slicing software must have the function of setting slicing parameters for each sub-model individually; second, the slicing software must ensure accurate assembly of each sub-model. The former has been solved by slicing software developers, while a good solution for the latter is currently lacking.

[0024] Therefore, in this embodiment, different reference planes can be constructed according to the height position of each sub-model in the 3D model of the target workpiece. Then, multiple reference bodies can be constructed on each reference plane. Each reference body can contain the height position information of each sub-model. Each sub-model is then combined with multiple reference bodies of the corresponding height to generate multiple process models. Since the entire process model can contain the height position information of the corresponding reference bodies, the height setting parameters of multiple process models can be obtained from bottom to top when the multiple process models are imported into the slicing software. Based on the height setting parameters, the precise assembly of all sub-models can be completed, thereby realizing the precise assembly of each sub-model of the composite structure in the slicing software.

[0025] As an optional implementation, the multiple sub-models are denoted from bottom to top as first sub-model 1, second sub-model 2, ..., nth sub-model; In step S10, the multi-layer reference planes for 3D printing the target workpiece model are obtained, specifically including: Step S11: Obtain the first reference plane for 3D printing the target workpiece model; wherein the first reference plane is located below the lowest point of the target workpiece model 3D and has a preset distance; Step S12: Perform multiple offsets on the first reference plane from bottom to top to generate the second reference plane, ..., the nth reference plane located at the lowest point of the second sub-model 2, ..., the nth sub-model respectively.

[0026] In this embodiment, a first reference plane is first constructed based on the initial position of the target workpiece model during 3D printing (i.e., below the lowest point of the target workpiece model 3D). Then, according to the lowest point positions of the second sub-model 2, ..., and the nth sub-model, the first reference plane is shifted multiple times from bottom to top to construct the second reference plane, ..., and the nth reference plane respectively. This constructs the position reference reference planes corresponding to all sub-models, providing a prerequisite for the accurate construction of the reference body in the future.

[0027] As an optional implementation, in step S11, obtaining the first reference plane for 3D printing the target workpiece model specifically includes: Step S111: Combine the various sub-models into a single target workpiece model in the 3D modeling software; Step S112: Determine the placement position of the target workpiece model during printing, and construct the first reference plane for printing accordingly; wherein, the first reference plane is located 0-2mm below the lowest point of the 3D target workpiece model.

[0028] In this embodiment, the various sub-models can be combined into a whole target workpiece model in the 3D modeling software. Then, the placement position of the target workpiece model during printing can be determined, thereby constructing a first reference plane based on the lowest point of the 3D target workpiece model 0-2mm below.

[0029] As an optional implementation, in step S20, multiple reference bodies are constructed on each reference plane, including: Step S21: Project the target workpiece model onto the first reference plane to generate planar graphic 4; Step S22: Construct a first rectangle 5 that can enclose the planar figure 4; Step S23: Enlarge the first rectangle 5 to generate the second rectangle 6; Step S24: Construct a first reference body 7 of a preset size at each of the four corners of the second rectangle 6; Step S25: Construct four second reference bodies, ..., nth reference bodies respectively on the second reference plane, ..., nth reference plane, located directly above the corresponding first reference body 7.

[0030] In this embodiment, when constructing the reference body, the target workpiece model is first projected onto the first reference plane to generate a planar graphic 4. Then, a first rectangle 5 is constructed that can just enclose the planar graphic 4. The first rectangle 5 is then enlarged, with its length and width increased by 50mm-100mm respectively, to generate a new second rectangle 6. Then, a first reference body 7 of a preset size is constructed at each of the four corners of the second rectangle 6. At this point, the position of the first reference body 7 on the first reference plane represents the initial printing position of the first sub-model 1. Similarly, based on the position of the first reference body 7, the initial printing positions of the first sub-model 1 can be quickly established on the second reference plane, ... Four reference bodies, namely, the second reference body, ..., the nth reference body, are constructed on the nth reference plane and located directly above the corresponding first reference body 7. Since the first reference body 7, the second reference body, ..., the nth reference body and the corresponding first sub-model 1, second sub-model 2, ..., the nth sub-model are not spatially connected, during subsequent assembly, the assembly of each sub-model can be completed simultaneously by sequentially assembling the first reference body 7, the second reference body, ..., the nth reference body, which has height position information and is regular. Moreover, the target workpiece model formed after assembling each sub-model will not interfere with each reference body in space. Subsequently, each reference body can be hidden or eliminated, thus achieving the effect of balancing assembly accuracy and high efficiency.

[0031] It should be noted that the first datum body 7, the second datum body, ..., the nth datum body can all be 2*2*2mm cubes with regular shapes, which facilitates the extraction of their position information; the first datum body 7, the second datum body, ..., the nth datum body and the corresponding first sub-model, second sub-model, ..., the nth sub-model can be combined to form the corresponding first process model 8, second process model 9, ..., the nth process model; after combination, the first datum body 7, the second datum body, ..., the nth datum body and the corresponding first sub-model 1, second sub-model 2, ..., the nth sub-model must be in the same geometric model.

[0032] As an optional implementation, after constructing a first rectangle 5 that can encompass the planar graphic 4 in step S22, the method further includes: Step S221: Construct a local coordinate system based on the first rectangle 5; wherein the local coordinate system uses the long side of the first rectangle 5 as the X-axis and the short side as the Y-axis; Step S222: Transform the local coordinate system into a coordinate system consistent with the global coordinate system of the target workpiece model.

[0033] In this embodiment, after constructing the first rectangle 5, a local coordinate system can be constructed based on the first rectangle 5, and then the local coordinate system can be converted to be consistent with the global coordinate system of the target workpiece model. This will enable the subsequently constructed reference bodies to have corresponding position coordinate information. When multiple reference bodies are constructed, their corresponding position coordinate information can be saved. After being imported into the slicing software, the position coordinate information corresponding to the reference bodies can be retrieved to assist in completing rapid assembly.

[0034] As an optional implementation, after obtaining the multi-layer reference planes for 3D printing the target workpiece model, the method further includes: Obtain the distances L1, L2, ..., L from the first reference plane to the second reference plane, ..., the nth reference plane, respectively. n-1 .

[0035] In this embodiment, the distances from the first reference plane to the second reference plane, ..., the nth reference plane are calculated and denoted as L1, L2, ..., L... n-1 Saving this distance information can provide a data basis for subsequent calculations of the height setting parameters of each process model.

[0036] As an optional implementation, the multiple process models are referred to from bottom to top as the first process model 8, the second process model 9, ..., the nth process model; Import multiple process models into the slicing software, and sequentially obtain the height setting parameters of the multiple process models from bottom to top to complete the assembly, including: Obtain the height setting parameter H1 of the first process model 8; Based on the height setting parameter H1, the height setting parameters for the second process model 9, ..., the nth process model are obtained as H1+L1, ..., H1+L1, respectively. n-1 To complete the assembly.

[0037] In this embodiment, after importing multiple process models into the slicing software, during assembly, the position of the first process model is first set, and its height setting parameter H1 is the Z-axis coordinate (generally set to 0). Based on the position coordinate information of the corresponding reference body in the second process model 9, ..., the nth process model, the height setting parameters (i.e., Z-axis coordinates) of the second process model 9, ..., the nth process model can be obtained as H1+L1, ..., H1+L n-1 This allows for the accurate assembly of the first process model 8, the second process model 9, ..., the nth process model according to the Z-axis coordinate, which is efficient and fast.

[0038] In summary, the assembly method based on this embodiment has the following advantages: (1) It is simple to operate, realizing the transformation from manual assembly to digital precision assembly, and achieving zero error in the combination of sub-models of multi-performance composite structure; (2) It has a wide range of applications and is not limited by the number of combined sub-models or the configuration of the contact surface between sub-models; (3) It improves the efficiency and fault tolerance of the combination of sub-models of multi-performance composite structure.

[0039] Example 2 Reference Figures 1-6 This embodiment provides a typical multi-performance composite structure assembly method. The overall workpiece model of this typical multi-performance composite structure includes, from bottom to top, a first sub-model 1, a second sub-model 2, and a third sub-model 3. Due to application requirements, different process parameters need to be set for the three parts of the workpiece model: the first sub-model 1, the second sub-model 2, and the third sub-model 3. Please refer to... Figure 3 Based on the printing direction of the workpiece, determine the first reference plane of the workpiece (i.e., plane P1 in the figure). The gap between plane P1 and the lowest point of the workpiece is approximately 0.6mm. Please refer to... Figure 4 Project the workpiece onto plane P1 to form planar figure 4, and draw a first rectangle 5 that just encloses planar figure 4. Construct a local coordinate system using the length and short sides of the first rectangle 5. Use the coordinate transformation function in the 3D modeling software CATIA to transform this local coordinate system to be consistent with the global coordinate system; please refer to... Figure 5Enlarge the perimeter of the first rectangle 5 by 60mm to generate the second rectangle 6. Draw a first reference body 7 (cube D1 in the figure) with a diameter of 2*2*2mm at the four corners of the second rectangle 6. In CATIA, offset plane P1 so that the offset plane passes through the lowest point of the second sub-model 2 to generate the second reference plane (plane P2 in the figure). On plane P2, draw four identical second reference bodies (cube D2 in the figure) vertically above the first reference body 7. Similarly, generate the third reference plane (plane P3 in the figure) and draw the third reference body (cube D3 in the figure). Combine the first sub-model 1 and the first reference body 7 into a whole first process model 8. Combine the second sub-model 2 and the second reference body into a whole second process model 9. Combine the third sub-model 3 and the first reference body into a whole second process model 9. The three reference bodies are combined into a single third process model 10. The first process model 8, the second process model 9, and the third process model 10 are simultaneously imported into the slicing software Cura. First, the position of the first process model 8 is determined, and its Z-axis coordinate is set to 0. The X and Y axes of the second process model 9 are consistent with those of the first process model 8. By measuring the distance between plane P2 and plane P1, which is 11mm, the Z-axis of the second process model 9 is set to 11mm. The X and Y axes of the third process model 10 are consistent with those of the first process model 8. By measuring the distance between plane P3 and plane P1, which is 18mm, the Z-axis of the third process model 10 is set to 18mm. Thus, the precise assembly of the first process model 8, the second process model 9, and the third process model 10 in the slicing software is achieved.
