[0051] See also Figure 1 , an embodiment of the present invention provides a speaker mesh modeling method, comprising:

[0056] S50, continue to identify closed curves in the target area, and use the identified closed curves as boundaries to make holes in the entity until the closed curves in the target area are completely identified.

[0057] In the speaker mesh modeling method of the embodiment of the present invention, the surface without holes is thickened to generate a solid body to be holed; the holed surface is superimposed on the surface of the solid body; a closed curve is identified in a target area on the holed surface, the target area being the current holed area; holes are made in the solid body with the identified closed curve as the boundary according to the type of holes to be made; closed curves are continuously identified in the target area, and holes are made in the solid body with the identified closed curve as the boundary until the closed curves in the target area are completely identified. The embodiment of the present invention can automatically thicken the surface of the hole to be made to produce a solid body, and by automatically identifying the closed curves on the holed surface, holes are made in the solid body with the closed curve as the boundary according to the type of holes to be made, thereby realizing modeling automation, reducing the repetitive work of designers, and saving human resources and time costs.

[0058] In some embodiments, thickening the surface without holes to generate the entity to be opened may include: selecting the speaker mesh area before the opening as the surface without holes, and thickening the surface without holes based on the thickening direction and thickness parameters to obtain the entity. The designer can select the specific speaker mesh area before the opening as the surface without holes through the interactive interface, and can set the thickening direction and the total thickness of the entity through the interactive interface, so that the entity with the set thickness can be automatically thickened according to the surface without holes, the thickening direction and the thickness parameters.

[0059] In an embodiment of the present invention, the types of holes to be opened on a solid body may include through holes, stepped holes, and blind holes. When the types of holes to be opened on a solid body include stepped holes and / or blind holes, thickening the surface without holes to generate a solid body to be opened may include: setting a parting surface in the solid body according to the parameters of the stepped holes and / or blind holes. Setting the parting surface in the solid body can quickly and accurately realize the opening of stepped holes and / or blind holes in the solid body. The parameters of the stepped holes and / or blind holes include the step depth of the stepped holes and the depth of the blind holes.

[0060] In some embodiments, the surface without a hole is thickened to generate a solid body to be drilled, including: the hole to be drilled includes a stepped hole, and a first parting surface is set in the solid body according to the step depth of the stepped hole, so that the step surface of the stepped hole is located on the first parting surface. The first parting surface is set in the solid body according to the step depth of the stepped hole, and when the stepped hole is drilled in the solid body, the step surface of the stepped hole can be positioned according to the first parting surface, so that the stepped hole can be drilled quickly and accurately in the solid body.

[0061] In some embodiments, the surface without a hole is thickened to generate a solid body to be drilled, including: the hole to be drilled includes a blind hole, and a second parting surface is set in the solid body according to the depth of the blind hole, and the second parting surface divides the solid body into a first part and a second part, and the thickness of the first part is equal to the depth of the blind hole. The second parting surface is set in the solid body according to the depth of the blind hole, and when the blind hole is drilled in the solid body, the bottom of the blind hole can be located according to the second parting surface, so that the blind hole can be drilled quickly and accurately in the solid body.

[0062] Designers can select a specific speaker mesh area before the opening as the un-opened surface through the interactive interface, and can set the thickening direction, the total thickness of the entity, and the depth of the parting surface in the entity through the interactive interface. Thus, a solid of a set thickness can be automatically thickened and generated according to the un-opened surface, the thickening direction, the thickness parameters, and the depth of the parting surface, and the solid includes the first parting surface and / or the second parting surface.

[0063] When there are multiple types of holes to be opened on a solid, different types of holes are in different areas of the opening surface. When opening holes, one of the areas is selected as the target area for opening holes, and the type of holes in the area can be determined. If the types of holes to be opened in the area are the same, the opening operation of all holes of the same type can be automatically completed.

[0064] For example, the types of holes to be opened on the entity include stepped holes and blind holes, the stepped holes are in the first area of ​​the opening surface, and the blind holes are in the second area of ​​the opening surface, and opening the entity with the identified closed curve as the boundary may include determining the type of opening according to the current opening area. When the current opening area is the first area, the type of hole to be opened is a stepped hole, and when the current opening area is the second area, the type of hole to be opened is a blind hole.

[0065] Alternatively, the types of holes to be opened on the entity include through holes and blind holes, the step holes are in the third area of ​​the opening surface, the blind holes are in the fourth area of ​​the opening surface, and opening the entity with the identified closed curve as the boundary may include determining the type of opening according to the current opening area. When the current opening area is the third area, the type of hole to be opened is a step hole, and when the current opening area is the fourth area, the type of hole to be opened is a blind hole.

[0066] Designers can select the current opening area through the interactive interface to complete the opening operation of all holes in the target area.

[0067] In the embodiment of the present invention, the opening surface has a designed hole layout, and the entity is opened according to the hole layout. When identifying a closed curve on the opening surface, a boundary recognition method can be used. In a specific implementation, identifying a closed curve in a target area on the opening surface may include: pixel by pixel recognition along the X direction, when the grayscale value of the pixel is recognized to reach a set value, it can be determined that the pixel is located on a closed curve, and the coordinates of the pixel are recorded, and the pixels adjacent to it are continuously identified until the pixel whose grayscale value reaches the set value coincides with the first pixel identified, that is, the coordinates of the two pixels are the same, and a complete closed curve is identified.

[0068] In some embodiments, when the type of hole to be opened is a through hole, the entity is opened with the identified closed curve as the boundary, including: inserting the entity into a cavity with the closed curve as the boundary to form a through hole on the entity, and drafting the through hole to form a through hole on the entity. Inserting the entity into a cavity with the closed curve as the boundary can form a through hole on the entity. For example, a cavity can be generated with the closed curve as the boundary, and then the cavity is inserted into the entity along the thickening direction. Drafting the through hole can complete the opening of a through hole.

[0069] In some embodiments, when the type of hole to be opened is a through hole, the entity is opened with the identified closed curve as the boundary, including: stretching the closed curve, trimming the entity with the stretched body formed by stretching, forming a through hole on the entity, and drafting the through hole to form a through hole on the entity. By stretching the closed curve, a stretched body with a circumferential closed surface can be formed, and by trimming the entity with the stretched body, the entity inside the stretched body can be trimmed away, thereby forming a through hole on the entity. Drafting the through hole can complete the opening of a through hole.

[0070] In some embodiments, when the type of hole to be opened is a step hole, the entity is opened with the identified closed curve as the boundary, including:

[0071] A through hole is formed on a solid with a closed curve as the boundary;

[0072] The surface of the through hole is divided into a first hole area and a second hole area by a first parting surface, the first hole area is connected to the front mold, and the second hole area is connected to the rear mold;

[0073] The first hole area or the second hole area is biased so that a step is formed between the first hole area and the second hole area;

[0074] Drafting is performed on the first hole area or the second hole area to obtain a stepped hole.

[0075] The stepped hole runs through the two sides of the entity. When the opening type is a stepped hole, a through hole is first formed on the entity with a closed curve as the boundary, and then the surface of the through hole is divided into a first hole area and a second hole area by the first parting surface. For example, the first hole area is above the first parting surface, and the second hole area is below the second parting surface. The first hole area or the second hole area can be offset to achieve hole expansion in the first hole area or the second hole area, and the first hole area or the second hole area after expansion is demolded to complete the opening of the stepped hole. The offset size can be determined according to the parameters of the stepped hole. For example, if the radius difference between the two sections of the stepped hole is 0.1mm, the offset size is set to 0.1mm. After the offset, a step surface with a width of 0.1mm is directly formed in the first hole area and the second hole area.

[0076] In the step of drilling the step hole, the method of forming the through hole may be the same as the method of drilling the through hole.

[0077] In some embodiments, forming a through hole on a solid body with a closed curve as a boundary includes: inserting a cavity into the solid body with a closed curve as a boundary to form a through hole on the solid body. Inserting a cavity into the solid body with a closed curve as a boundary can form a through hole on the solid body. For example, a cavity can be generated with a closed curve as a boundary, and then the cavity is inserted into the solid body along a thickening direction to form a through hole on the solid body.

[0078] In some embodiments, forming a through hole on a solid body with a closed curve as a boundary includes: stretching the closed curve, trimming the solid body using the stretched body formed by the stretching, and forming the through hole on the solid body. By stretching the closed curve, a stretched body with a circumferential closed surface can be formed, and by trimming the solid body using the stretched body, the solid inside the stretched body can be trimmed away, thereby forming a through hole on the solid body.

[0079] In some embodiments, when the type of the hole to be opened is a blind hole, the entity is opened with the identified closed curve as the boundary, including:

[0080] Use the second parting surface to split the entity into a first part and a second part, with the opening surface located in the first part;

[0081] forming a through hole on the first portion according to the identified closed curve;

[0082] Draft the through holes;

[0083] Merges the first part with the second part to form a blind hole in the solid.

[0084] Only one end of the blind hole extends to the surface of the entity. The entity is split by the second parting surface to obtain a relatively independent first part and a second part. A through hole is formed on the first part according to the identified closed curve, and demolding is performed. Then the two parts are merged to form a blind hole on the entity. The second parting surface is set in the entity according to the depth of the blind hole. Therefore, the thickness of the first part split by the second parting surface is equal to the depth of the blind hole. The method of forming a through hole on an entity is relatively simple, convenient and quick. The embodiment of the present invention uses a parting surface to split the entity to form a through hole, and then merges it into one entity, so that the opening of the blind hole can be easily realized.

[0085] In the step of drilling the blind holes, the method of forming the through holes may be the same as the method of drilling the through holes.

[0086] In some embodiments, forming a through hole on the first part according to the identified closed curve includes: inserting a cavity into the first part with the closed curve as a boundary to form a through hole on the first part. Inserting the first part into the cavity with the closed curve as a boundary can form a through hole on the first part. For example, a cavity can be generated with the closed curve as a boundary, and then the cavity is inserted into the first part along the thickening direction to form a through hole on the first part.

[0087] In some embodiments, forming a through hole on the first part according to the identified closed curve includes: stretching the closed curve, trimming the first part using the stretched body formed by the stretching, and forming the through hole on the first part. By stretching the closed curve, a stretched body with a circumferential closed surface can be formed, and by trimming the first part using the stretched body, the entity inside the stretched body can be trimmed away, thereby forming the through hole on the first part.

[0088] The method of the embodiment of the present invention can be implemented based on NX / UIStyler and NX / Block UI open interfaces.

[0089] When implementing the modeling method of the embodiment of the present invention, the designer can input the corresponding parameters through the interactive interface, and the electronic device executing the method of the present invention can automatically build the model, which can be done during the idle time of the electronic device, thereby improving the modeling efficiency. In addition, it can reduce the manpower input, avoid problems caused by human errors due to repeated manual operations, and improve the design quality. The operation flexibility is high.

[0090] In the method of the present invention, automatic saving can also be performed at a fixed time to prevent problems from occurring during the process, which may cause the completed work to be invalidated.
