Description

Technical Field

[0001] This application relates to the field of tires, and in particular to an automatic support method, device, terminal, and medium suitable for tire models. Background Technology

[0002] The tire model includes the tread surface, bottom surface, and four sidewalls. Currently, when adding a honeycomb structure to the tire, technicians need to manually pick up the bottom surface of the tire and set the corresponding honeycomb structure. When automatically adding supports to the tire model, it is unavoidable to generate supports on the tread surface. After printing, it is not only difficult to remove the support structures on the tread surface, but it also affects the surface quality of the tread. The solution to the above problems is to manually remove the tread surface supports during preprocessing, but this method has a very high labor cost. Furthermore, when automatically adding supports to the tire model, it is not possible to add multiple types of supports with one click, and it is difficult to achieve structural supports with strict requirements, requiring manual addition of corresponding supports.

[0027] This application provides an automatic support method, device, terminal, and medium for tire models.

The unsupported areas of all surface patches on the tire model are cleared, and block supports are generated for the regions corresponding to each identified planar surface patch of the tire model.

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the invention.

[0029] like Figure 1The diagram shown is a flowchart of an automatic support method for tire models in an embodiment of the present invention.

[0030] The automatic support method applicable to tire models includes:

[0031] Step S101: Set all facets on the surface of the tire model to an unsupported region state.

[0032] The types of surface patches on the tire model include: flat surface patches and tread pattern surface patches.

[0033] In detail, the surface of the tire model includes: one tread pattern surface and five flat surface pieces; of the five flat surface pieces, four are side surface pieces, and the remaining one is the bottom surface piece.

[0034] In one specific embodiment, the patterned surface patch is Figure 2 The plane surface pointed to by arrow A includes: Figure 3 The planes pointed to by the middle arrow are plane 1, plane 2, plane 3, plane 4 and plane 5; among them, the side planes include: plane 2, plane 3, plane 4 and plane 5.

[0035] Optionally, when adding supports to a tire model, the area corresponding to a face that is set to an unsupported area cannot be supported.

[0036] Step S102: Using the identified bottom planar surface of the tire model as the opening surface, add a honeycomb structure to the interior of the tire model, set each honeycomb structure surface to an unmarked state, and keep all surfaces of the tire model in an unsupported area state.

[0037] Optionally, the method for identifying the bottom planar surface of the tire model includes: identifying the planar surface with the largest area among all the surface patches of the tire model, and using it as the bottom planar surface of the tire model. For example, such as Figure 3 As shown, the area corresponding to planar surface 1 in the tire model is the largest area in the tire model, so planar surface 1 is identified as the bottom planar surface of the tire model.

[0038] Optionally, the step of using the bottom planar surface of the identified tire model as an opening surface and adding a honeycomb structure to the interior of the tire model includes: using the bottom planar surface of the identified tire model as an opening surface and adding honeycomb structure pieces to the interior of the tire model with its normal direction as the extending direction.

[0039] Optionally, when adding supports to the tire model, supports can be added to the areas corresponding to each honeycomb structure patch that is set to an unmarked state.

[0040] It should be noted that the honeycomb structure in the above embodiments is... Figure 4 The honeycomb structure shown.

[0041] Step S103: Generate smart supports for each honeycomb structure patch area in the tire model that is set to an unmarked state, so as to add smart supports to the inside of the honeycomb structure.

[0042] Optionally, the method for generating the intelligent support includes:

[0043] The honeycomb structure is cut according to the set layer thickness to generate slices in each layer;

[0044] For slices that meet the support point generation conditions, corresponding support points are generated, and SLA supports with truss structures as the support body are generated based on each support point.

[0045] SLA support is a support structure that utilizes SLA (Stereolithography Appearance) technology. Stereolithography primarily uses photosensitive resin as raw material, leveraging the property that liquid photosensitive resin rapidly cures under ultraviolet laser irradiation. Photosensitive resin is generally liquid; under ultraviolet light of a specific wavelength (250nm–400nm), it immediately undergoes a polymerization reaction, completing curing. SLA focuses ultraviolet light of a specific wavelength and intensity onto the surface of the photocurable material, causing it to solidify sequentially from point to line, and from line to surface, thus completing the drawing of a layer's cross-section. Layers are then stacked in this way to complete the printing of a three-dimensional solid. The advantages of SLA technology are its fast molding speed and the high smoothness and precision of the produced solid surface.

[0046] Optionally, the number of slices generated by cutting the honeycomb structure into each layer is related to the set layer thickness.

[0047] It should be noted that the truss structure in this embodiment is as follows: Figure 5 As shown; the layer thickness is set according to actual needs, and the present invention does not limit the comparison.

[0048] Optionally, generating corresponding support points for slices that meet the support point generation conditions includes: obtaining redundant contours obtained by comparing the contours of the current layer slice and the previous layer slice; determining whether the tilt angle calculated by the maximum offset distance corresponding to the redundant contour and the set layer thickness is within the range of intelligent support angle; if it is within the range of intelligent support angle, then generating support points for the current layer slice; if it is not within the range of intelligent support angle, then not generating support points for the current layer slice.

[0049] Optionally, each slice corresponds to a Z-axis height; the order of the slices is the order of their corresponding Z-axis heights from smallest to largest; support points for each slice are generated according to the order of their Z-axis heights from smallest to largest.

[0050] For example, the first slice has the smallest height in the Z-axis direction, and the current slice has a greater height in the Z-axis direction than the previous slice.

[0051] Optionally, the two-dimensional contours corresponding to the current layer slice and the two-dimensional contours corresponding to the previous layer slice are compared to obtain redundant contours; wherein, the redundant contours are the extra two-dimensional contours obtained by comparing the two-dimensional contours corresponding to the current layer slice and the two-dimensional contours corresponding to the previous layer slice.

[0052] Optionally, the method for obtaining the maximum offset distance includes: offsetting the redundant contour until there is no contour, at which point the offset value is the maximum offset distance; wherein, the method for offsetting the redundant contour includes: compressing the region corresponding to the redundant contour; the redundant contour is two-dimensional. Optionally, the intelligent support angle range is the range of angles from which corresponding support points can be generated for the current layer slice.

[0053] Optionally, since there needs to be a certain distance between each support point, the number of support points corresponding to the current layer slice is also limited by the number of support points corresponding to all previous layer slices.

[0054] For example, if the current layer is layer 7, the number of support points corresponding to the slice of layer 7 is limited by the number of support points corresponding to the slices of layers 1 to 6. This is because the support points corresponding to the slice of layer 7 need to be at a certain distance from the support points corresponding to the slices of layers 1 to 6.

[0055] It should be noted that the range of intelligent support angles can be set according to actual needs, and this invention does not limit this.

[0056] The following will illustrate the method for generating corresponding support points for slices that meet the support point generation conditions, using the above embodiments as examples:

[0057] Example 1: Generate multiple support points for the first layer slice.

[0058] The redundant contour is obtained by comparing the 2D contour corresponding to the first layer slice with the 2D contour corresponding to the 0th layer slice. Since there is no 0th layer slice, it means that the 0th layer slice is empty, and the obtained redundant contour is the 2D contour corresponding to the first layer slice. It is then determined whether the tilt angle calculated from the maximum offset distance corresponding to the 2D contour corresponding to the first layer slice and the set layer thickness is within the range of the intelligent support angle. If it is within the range of the intelligent support angle, support points for the first layer slice are generated; otherwise, support points for the first layer slice are not generated.

[0059] Example 2: Generate multiple support points for the i-th layer slice.

[0060] The redundant contour is obtained by comparing the 2D contour corresponding to the i-th layer slice with the 2D contour corresponding to the (i-1)-th layer slice. It is then determined whether the tilt angle calculated from the maximum offset distance corresponding to the redundant contour and the set layer thickness is within the range of the intelligent support angle. If it is within the range, support points for the i-th layer slice are generated; otherwise, support points for the i-th layer slice are not generated.

[0061] In this embodiment, i represents the sequence number of each layer; the smaller i is, the smaller the height of the slice in the Z-axis direction corresponding to the i-th layer; the maximum value of i is the number of slices generated in each layer by cutting the honeycomb structure; the maximum value of i is related to the set layer thickness.

[0062] It should be noted that the present invention does not bias the redundant contours in the actual model until there are no contours.

[0063] Step S104: Clear the unsupported areas of all facets on the surface of the tire model, and generate block supports for the areas corresponding to the large flat facets of the identified tire model.

[0064] Optionally, the method for identifying the large flat surface of the tire model includes: identifying the flat surface of the tire model surface whose normal direction is consistent with the normal direction of the identified bottom flat surface of the tire model, together with the bottom flat surface, as the large flat surface.

[0065] For example, the bottom planar surface of the tire model is Figure 6 The planar surface pointed to by the middle arrow C has its normal direction aligned with the normal direction of the bottom planar surface of the tire model. Figure 6 The face pointed to by the middle arrow B is identified together with the bottom plane face as a large plane face. The area corresponding to this face and the area corresponding to the bottom plane face are the areas corresponding to the large plane face. Then, block supports are generated for the areas corresponding to the large plane face. Figure 6 The support pointed to by the middle arrow D.

[0066] Optionally, the block support adopts SLA support.

[0067] It should be noted that the addition of intelligent supports and generated block supports to the honeycomb structure in the above embodiments is to prevent material from sagging during printing, which would affect the success rate of tire model printing. The automatic support method applicable to tire models will be described in detail below with reference to the above embodiments:

[0068] First, Figure 2 The patterned surface area pointed to by the middle arrow A and Figure 3 Planar patches 1 to 5 are set as unsupported areas. The bottom surface of the identified tire model is used as the opening surface, i.e., planar patch 1 is used as the opening surface. The normal direction of planar patch 1 is determined and used as the extension direction to add a honeycomb structure into the tire. The honeycomb structure added into the tire can achieve tire weight reduction.

[0069] To prevent material sagging during printing and affecting the success rate of tire model printing, smart supports need to be added to the honeycomb structure. Since the honeycomb structure's individual honeycomb surface areas are in an unmarked state, and planar surfaces 1 to 5 are unsupported, smart supports are generated for the unmarked honeycomb surface areas during the smart support addition process, while planar surfaces 1 to 5 do not. This avoids generating supports on the tread pattern surface, which could negatively impact the surface support of the tread pattern after printing.

[0070] After generating the intelligent support, clear the unsupported areas of planar patches 1 to 5, and as follows: Figure 6 As shown, the surface of the tire model whose normal direction is consistent with the normal direction of the bottom plane surface of the tire model is... Figure 6 The patch pointed to by the middle arrow B is identified as a planar patch along with the bottom planar patch. Then, the regions corresponding to this patch and the regions corresponding to the bottom planar patch are generated as follows: Figure 6 The block support shown.

[0071] Similar to the principles of the above embodiments, the present invention provides an automatic support device suitable for tire models.

[0072] The following specific embodiments are provided in conjunction with the accompanying drawings:

[0073] like Figure 7 The diagram shown is a structural schematic of an automatic support device applicable to a tire model in an embodiment of the present invention.

[0074] The automatic support device 7 for tire models includes:

[0075] The state setting module 71 is used to set all the surface patches of the tire model to an unsupported area state; the types of surface patches include: flat surface patches and tread surface patches;

[0076] The honeycomb structure adding module 72 is connected to the state setting module 71 and is used to add a honeycomb structure into the interior of the tire model by taking the identified bottom plane of the tire model as the opening surface, and set each honeycomb structure of the honeycomb structure to an unmarked state, and keep all the surface pieces of the tire model in an unsupported area state.

[0077] The intelligent support addition module 73 is connected to the honeycomb structure addition module 72 and is used to generate intelligent supports for each honeycomb structure patch area in the tire model that is set to an unmarked state, so as to add intelligent supports into the honeycomb structure.

[0078] The block support addition module 74, connected to the intelligent support addition module 73, is used to clear the unsupported areas of all facets on the surface of the tire model and generate block supports for the areas corresponding to each plane facet of the identified tire model.

[0079] Since the device in this embodiment can achieve all the functions of the above embodiments, it will not be repeated here.

Alternatively, it can be stored as program code in the memory of the above device, and its function can be called and executed by a processing element of the above device. The implementation of other modules is similar. In addition, these modules can be fully or partially integrated together, or implemented independently. The processing element mentioned here can be an integrated circuit with signal processing capabilities.

[0081] For example, these modules can be one or more integrated circuits configured to implement the above methods, such as one or more Application Specific Integrated Circuits (ASICs), one or more digital signal processors (DSPs), or one or more Field Programmable Gate Arrays (FPGAs). As another example, when a module is implemented using processing element scheduler code, the processing element can be a general-purpose processor, such as a Central Processing Unit (CPU) or other processor capable of calling program code. Furthermore, these modules can be integrated together to form a system-on-a-chip (SOC).
