[0022] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention in a schematic manner, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0024] As shown in FIG1 , in view of the lack of a process intelligence system based on computer technology, advanced algorithms and artificial intelligence in the prior art, the present application provides a method for automatically generating a part manufacturing process executed by an electronic device, comprising the following steps:

[0025] S11: Obtain part information of the part to be processed.

[0026] In detail, the part information is divided into geometric information and non-geometric information. Geometric information includes: part category, part space size, etc., which are extracted by electronic equipment from the two-dimensional or three-dimensional model of the part to be processed. The two-dimensional model is, for example, a part model drawn by drawing software such as CAD, and the three-dimensional model is, for example, a part model drawn by drawing software such as SolidWorks. Non-geometric information includes: code, name, material, technical requirements, roughness, shape and position tolerance, etc., which are extracted by electronic equipment from the electronic drawings of the part to be processed. The formats of the electronic drawings include but are not limited to word, PDF, etc.

[0027] by Figure 2 For example, Figure 2 Based on the shape projection of the part 3D model, the extraction of part geometric information specifically includes the following steps:

[0028] I. Automatic identification of part categories: Obtain part dimensions and shape information through 3D projection, and determine part categories (such as rotary shafts, gears, plates, etc.) by comparing the dimensions and shape information of several parts in the part type library; After determining the part category, automatically generate blank information based on the part dimensions, including blank type and size, material quota, etc.;

[0029] II. Automatically identify the spatial dimensions of parts: obtain the length, width and height dimensions required for storage, and automatically calculate the weight of parts. These data are suitable for workstation equipment, intelligent warehousing, logistics and transportation, etc.

[0030] III. Automatic calculation of surface area: Calculate the surface area of ​​parts based on part category data and part space size data, thereby providing reference data for surface treatment processes such as plating and painting.

[0031] by Figure 3 For example, Figure 3 Part of the content of the electronic drawing in PDF format is displayed. The extraction of non-geometric information of parts specifically includes the extraction of ① coding and name information, ② material information, ③ technical requirement information, ④ roughness, shape and position requirements and other symbol recognition contained in the PDF drawing based on text recognition technology: Ra1.6, Ra0.8, parallelism, verticality, etc.

[0032] S12: Generate the blank information and process information of the part to be processed according to the part information.

[0033] Specifically, the process of generating the blank information of the part to be processed according to the part information includes: comparing the geometric part information of the part to be processed with the geometric part information in the part type library; identifying the type of the part to be processed according to the comparison result, and then generating the blank information according to the external dimensions of the part to be processed. Figure 2The principle of generating blank information has been introduced in detail in the example, so it will not be repeated here.

[0034] Specifically, the process of generating the process information of the part to be processed based on the part information includes: searching for processed parts that are identical or similar to the part to be processed, as well as the historical process information of the processed parts in a process relationship database; displaying the historical process information for user modification, and generating the process information of the part to be processed after modification.

[0035] It should be noted that the process relationship database is a database established based on the relevant information of each processed part, and the process relationship database at least stores the part information and historical process information of each processed part, and the process information includes but is not limited to the process flow, the processing equipment of each processing step, etc. This step compares the part information of the part to be processed with the part information of the processed part in the process relationship database, thereby finding the processed part that is the same or similar to the part to be processed, and then obtaining the historical process information corresponding to the processed part.

[0036] For similar processed parts, since their historical process information is not completely applicable to the parts to be processed, users are required to make fine adjustments based on the historical process information to form process information that is unique to the parts to be processed.

[0037] See also Figure 4 In one embodiment, when executing step S12, the process relationship database may contain more than one processed parts similar to the part to be processed. When the number of similar processed parts found is multiple, this step first sorts them from high to low according to the degree of similarity, and then displays the sorted processed parts and their historical process information for user selection and modification. It should be noted that the judgment of similarity can be based on algorithms such as cluster analysis and machine learning. Since these algorithms are not the focus of the present invention, they will not be introduced in detail here.

[0038] In this way, users only need to make minor adjustments based on the process information of the parts to be processed recommended by the electronic device to obtain the process information of the parts to be processed, which greatly improves work efficiency.

[0039] S13: Generate a process document based on the blank information and the process information, and use it for the production of the parts to be processed after being reviewed and approved.

[0040] Preferably, the process document can be used for the production of the parts to be processed after passing the manual review. In addition, the part information, blank information and process information of the parts to be processed can be added to the database, thereby continuously expanding the amount of information in the database, which is conducive to gradually improving the accuracy of information recommendation of big data. If the process document fails the manual review, the user can be notified to modify it, and then re-manually review it after the modification.

[0041] All or part of the steps of implementing the above-mentioned method embodiments can be completed by hardware related to the computer program. Based on such understanding, the present invention also provides a computer program product, including one or more computer instructions. The computer instructions can be stored in a computer-readable storage medium. The computer-readable storage medium can be any available medium that a computer can store or a data storage device such as a server or a data center that includes one or more available media integrated. The available medium can be a magnetic medium (such as a floppy disk, a hard disk, a magnetic tape), an optical medium (such as a DVD), or a semiconductor medium (such as a solid-state hard disk (SSD)), etc.

Since the technical principle of this embodiment is similar to that of the aforementioned method embodiment, the same technical details will not be repeated. The device 50 of this embodiment includes the following modules:

Moreover, these modules can be implemented in the form of software calling through processing elements, or in the form of hardware, or some modules can be implemented in the form of software calling through processing elements, and some modules can be implemented in the form of hardware.

[0049] The system bus mentioned above can be a Peripheral Pomponent Interconnect (PCI) bus or an Extended Industry Standard Architecture (EISA) bus, etc. The system bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, only one thick line is used in the figure, but it does not mean that there is only one bus or one type of bus. The communication interface is used to realize the communication between the database access device and other devices (such as clients, read-write libraries, and read-only libraries).
