Furthermore, it should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Referring to fig. 1, a schematic block diagram of an electronic device 100 according to an embodiment of the present disclosure is shown. In the embodiment of the present application, the electronic device 100 may be a computer or a server, which is not limited in the embodiment of the present application.
Structurally, electronic device 100 may include a processor 110 and a memory 120.

The mechanical icon means includes at least one software module which may be stored in the memory 120 in the form of software or Firmware (Firmware) or solidified in an Operating System (OS) of the electronic device 100. The processor 110 is configured to execute executable modules stored in the memory 120, such as software functional modules and computer programs included in the mechanical icon annotating device, so as to implement the mechanical icon annotating method.
The processor 110 may execute the computer program upon receiving the execution instruction. The processor 110 may be an integrated circuit chip having signal processing capabilities. The Processor 110 may also be a general-purpose Processor, for example, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a discrete gate or transistor logic device, a discrete hardware component, which can implement or execute the methods, steps, and logic blocks disclosed in the embodiments of the present Application, and furthermore, the general-purpose Processor may be a microprocessor or any conventional Processor.

It should be understood that the structure shown in fig. 1 is merely an illustration, and the electronic device 100 provided in the embodiment of the present application may have fewer or more components than those shown in fig. 1, or may have a different configuration than that shown in fig. 1. Further, the components shown in fig. 1 may be implemented by software, hardware, or a combination thereof.
Please refer to fig. 2, which is a flowchart illustrating a mechanical icon annotation method according to an embodiment of the present disclosure, the method is applied to the electronic device 100 shown in fig. 1. It should be noted that, the mechanical icon notation method provided in the embodiment of the present application is not limited to the sequence shown in fig. 2 and the following, and the specific flow and steps of the mechanical icon notation method are described below with reference to fig. 2.
Step S100, after the target model is imported into the drawing software, the target model is obtained.
In the embodiment of the present application, the target model may be a mechanical model created by mapping software such as Creo parameter, 3Ds MAX, Solidworks, pro, and unicetics NX, and generally belongs to a three-dimensional model, and the "mapping software" described in step S100 of the embodiment of the present application may be any one of the mapping software such as Creo parameter, 3Ds MAX, Solidworks, pro, and unicetics NX. However, it should be noted that the "mapping software" described in step S100 of the embodiment of the present application and the software for creating the target model may be the same mapping software or different mapping software. For example, the target model is a mechanical model created by Solidworks, and the "cartographic software" described in step S100 of the embodiment of the present application may be Creo parameter, as long as the "cartographic software" described in step S100 can smoothly open the target model.
Further, the modeling types of the machine drawings are generally classified into a component class and a part class, and for the component class, which generally includes a plurality of parts, the part class is actually a machine model including one part, and the modeling types of the machine drawings are distinguishable by file formats, for example, the file format of the component class is "asm", "sldasm", or the like, and the file format of the part class is "prt", "sldprt", or the like. Based on this, the mechanical icon annotation method provided in the embodiment of the present application may further include step S001 and step S002 after step S100 is executed to import the target model into the drawing software.
And S001, judging whether the file format of the target model belongs to an agreed format.
Judging whether the file format of the target model is in an "asm" format, an "sldasm" format, a "prt" format or an "sldprt" format, if the file format of the target model is in the "asm" format, the "sldasm" format, the "prt" format or the "sldprt" format, indicating that the file format of the target model belongs to an agreed format, that is, the agreed format is in the "asm" format, the "sldasm" format, the "prt" format or the "sldprt" format, but not limited thereto.
And step S002, if the file format of the target model belongs to the agreed format, executing the step of judging whether the target model meets the preset labeling requirement.
In the embodiment of the present application, if the file format of the target model belongs to the agreed format, the subsequent steps are directly executed, that is, step S200, to determine whether the target model meets the preset labeling requirement, and if the file format of the target model does not belong to the agreed format, the labeling is ended and an error is reported.
In addition, in the embodiment of the present application, if the file format of the target model does not belong to the agreed format, for example, the file format is a general format such as "step" or "stp", the target model may be converted from the "step" format or "stp" format into the agreed format, then step S200 is performed to determine whether the target model meets the preset labeling requirement, and if the target model cannot be converted into the agreed format, the labeling is terminated and an error is reported, so as to avoid that the wrong execution affects the labeling efficiency.
And step S200, judging whether the target model meets the preset labeling requirement.
In general, a mechanical model with strong readability needs to be complete, and there is no overall interference with the target model, where the mechanical model is complete and can be understood as: with a modelled coordinate system, reference datum and full view etc. and incomplete mechanical models can be understood as: missing at least one of the modeled coordinate system, the reference datum and the full view, the global intervention with respect to the target model may be understood as: for example, if the model type of the target model is a component type, the interference between the parts in the plurality of parts included in the target model is not considered. However, during the processes of model splitting, model importing, model exporting, model format converting and the like, a modeling coordinate system, a reference plane or a complete view may be lost, and overall interference of the mechanical model with respect to the target model may also occur, and these situations all affect the labeling effect. Therefore, the mechanical icon annotation method provided by the embodiment of the application can also complete the target model, and has no integral interference about the target model as a perfect preset annotation requirement, so that after the target model is judged to meet the preset annotation requirement, the annotation effect can be ensured when the target model is integrally annotated.
Based on the above description, in the embodiment of the present application, the determining whether the target model meets the preset labeling requirement may specifically include: and judging whether the target model is complete and integrity interference about the target model does not exist, if the target model is complete and integrity interference about the target model does not exist, judging that the target model meets the preset labeling requirement, and if the target model is incomplete or integrity interference about the target model exists, judging that the target model does not meet the preset labeling requirement.
In order to further improve the annotation efficiency, the mechanical icon annotation method provided in the embodiment of the present application may further include step S003 and step S004 after step S200 is executed and whether the target model meets the preset annotation requirement is determined.
And S003, if the target model does not meet the preset labeling requirement, determining the error content causing the target model not to meet the preset labeling requirement.
With reference to step S200, it can be understood that, in the embodiment of the present application, the error content that causes the target model not to meet the preset labeling requirement may be at least one of a missing part of the modeling coordinate system, a missing part of the reference plane, and a missing part of the complete view, or an overall interference of the target model with respect to the target model, so that if the target model does not meet the preset labeling requirement, the error content that causes the target model not to meet the preset labeling requirement may be further determined, and meanwhile, a specific occurrence position of the error content may be calibrated.
And step S004, generating and displaying prompt information according to the error content.
After the error content causing the target model not to meet the preset labeling requirement is determined, prompt information is generated according to the error content, for example, the prompt information including the error content and the specific occurrence position of the error content can be generated and highlighted. Therefore, the operator can directly and manually correct the target model according to the prompt message without manually searching the error content and the specific occurrence position of the error content, and the labeling efficiency is further improved.
After the manual correction, step S200 may be executed again to determine whether the target model meets the preset labeling requirement, if the target model meets the preset labeling requirement after the manual correction, the subsequent steps are executed, that is, step S300 determines the modeling type of the target model to perform integral labeling on the target model by combining the modeling type, and if the target model does not meet the preset labeling requirement after the manual correction, through step S003 and step S004, the error content causing the target model not meeting the preset labeling requirement is determined again, and a prompt message is generated according to the error content and displayed to prompt the operator to perform manual correction on the target model again.
And step S300, if the target model meets the preset marking requirement, determining the modeling type of the target model, and marking the target model by combining the modeling type.
As mentioned above, for a mechanical model of a component class, which generally includes a plurality of parts, the part class is actually a mechanical model including one part, and therefore, in the actual labeling process, it is necessary to identify whether the modeling type of the target model is the component class or the part class, and a specific identification process can be implemented by identifying a file format of the target model, for example, the file format is "asm", "sldasm", etc., and then determining the modeling type of the target model is the component class, and the file format is "prt", "sldprt", etc., and then determining the modeling type of the target model is the part class.
If the modeling type of the target model is a component type, in this embodiment of the application, as a first optional implementation manner, it may be determined that the target model includes a plurality of parts, and for each part of the plurality of parts, a labeling form of the part is determined, and the part is labeled according to the labeling form, so as to complete the overall labeling of the target model. Based on this, it can be understood that, in the foregoing embodiment, if the modeling type of the target model is a component class, the labeling of each part in the target model may be considered to be completed only after the labeling of each part in the target model is completed.
If the modeling type of the target model is a component type, in this embodiment of the application, as a second optional implementation manner, the target model may also be wholly labeled, and it is determined that the target model includes a plurality of parts, and for each part of the plurality of parts, a labeling form of the part is determined, and the part is labeled according to the labeling form. Based on this, it can be understood that, in the foregoing embodiment, the whole labeling of the target model and the labeling of the plurality of parts included in the target model are performed independently, and in the foregoing embodiment, the whole labeling of the target model can be understood as: the target model is integrally used as an inseparable mechanical model, the visible part of the target model is subjected to integral marking, and when the target model is integrally marked, the adopted marking form can be preset according to business requirements, and the method is not limited in the embodiment of the application.
And if the modeling type of the target model is a part type, judging that the target model is a part, determining the marking form of the part, and marking the part according to the marking form to finish the overall marking of the target model. Based on this, it can be understood that, in the embodiment of the present application, if the modeling type of the target model is a part type, it is determined that the target model is a part, and then, it is only necessary to complete the labeling of the part to be considered to complete the overall labeling of the target model.
In addition, it should be noted that, in the embodiment of the present application, the labeling form may include a linear labeling and a coordinate labeling, but is not limited thereto.
In order to further improve the labeling efficiency, in the embodiment of the application, after the whole labeling of the target model is completed, the labeling result can be automatically corrected to avoid labeling errors such as interference and dislocation, and after the automatic correction is completed, the labeling error rate can be further reduced through manual correction.
Further, in the embodiment of the present application, a specific implementation process of "determining a labeling form of a part" includes: and acquiring the material number of the part to acquire a labeling form corresponding to the material number, namely, the corresponding relation between the material number and the labeling form is preset.
Each part has a unique corresponding material number, when a target model is introduced into drawing software, the material number can be introduced into the drawing software as model information of the target model, when the target model is displayed through the drawing software, the material number can be embodied in a design tree of the target model, and the corresponding relation between the material number and a labeling form can be set according to business requirements, for example, the labeling form corresponding to the material number 'BJ 20211156603' of a metal plate is 'linear labeling', and when the business requirements need to be changed, the labeling form corresponding to the material number 'BJ 20211156603' of the metal plate can be changed into 'coordinate labeling'. In addition, in the embodiment of the application, the corresponding relationship between the material number and the labeling form can be stored through a labeling form information table.
In the embodiment of the present application, the specific implementation process of "labeling a part according to a labeling form" is as follows: and calling the feature function library to perform feature recognition on the part through the feature data stored in the feature function library to obtain a feature recognition result, and labeling the part by combining the labeling form and the feature recognition result. The part feature recognition can be understood as recognizing part features such as holes, grooves and fillets on the part, and a large amount of feature data are stored in the feature function library, so that the part feature recognition can be performed through the feature data stored in the feature function library to obtain a feature recognition result, and then the part features represented by the feature recognition result can be labeled according to a labeling form.
Because the target model usually belongs to a three-dimensional model, after the target model is labeled, a three-dimensional labeling graph is usually obtained, and therefore, a mechanical engineering graph with labels at any required view angle can be output according to the requirements of an actual user in the subsequent graph guide process. Of course, if the modeling type of the target model is a component type, in the subsequent drawing guiding process, not only the mechanical engineering drawing with the label at any view angle of the target model itself can be output, but also the mechanical engineering drawing with the label at any view angle of each part in the target model can be output separately. Referring to fig. 3 and fig. 4, assuming that the target model is "a 01 rack class 1", the top view thereof is shown as the left part in fig. 3, and the left side view thereof is shown as the right part in fig. 3, after the target model is labeled, if only the labeled mechanical engineering drawing in the top view of the target model itself needs to be output in the subsequent drawing guiding process, the labeled mechanical engineering drawing shown in fig. 4 can be finally output.
As for the condition that the modeling type of the target model is a part type, because the target model is a part, the mechanical engineering drawing with the label at any view angle of the part can be output.
In order to ensure the comprehensiveness of the information included in the mechanical engineering drawing, in this embodiment of the application, if the modeling type of the target model is a component class, in the execution process of step S300, a Bill of Material (BOM) of the target model may also be called, so that after the target model is labeled, the mechanical engineering drawing including the labeling result and the BOM table is output, that is, the BOM table is appended to the mechanical engineering drawing of the target model itself. The labeling result is mainly determined according to the actual user requirement, namely, the mechanical engineering drawing with the label at any view angle of the target model is output according to the actual user requirement, and the mechanical engineering drawing with the label at any view angle of each part in the target model can also be independently output.
TABLE 1
As shown in Table 1, the BOM table may include the material number, drawing number, material name, material, specification, brand, quantity and remark information of each part in the target model. Based on this, the final output mechanical engineering drawing also comprises the BOM table besides the target model, so that the comprehensiveness of the information covered in the mechanical engineering drawing can be ensured.
A complete detailed description of the mechanical icon method provided by the embodiments of the present application will be described in conjunction with fig. 5.
