Description

Technology Field

[0001] This invention relates to a method and system for managing the entire mold manufacturing process, and more specifically, to a mold manufacturing management method and system that allows for a comprehensive overview of the mold manufacturing status of multiple parts and enables easy management of the mold manufacturing stages of each part. Background Technology

[0002] In modern manufacturing, the efficient management of the mold manufacturing process and quality assurance are becoming increasingly important alongside the growing demand for multi-product, small-batch production. The mold manufacturing process typically involves a client commissioning a design, a supplier manufacturing the mold according to the design, and then delivering it. If systematic management of the time, cost, and quality involved in this process is not implemented, it can lead to issues such as production schedule delays and quality defects.

[0003] In particular, the mold manufacturing process requires the exchange of various information, such as design drawings, quotations, and production status, between the client and multiple suppliers. During this process, problems frequently arise, including inefficiencies in information exchange, errors caused by manual work, and quality degradation resulting from incomplete inspections. Furthermore, tasks such as analyzing drawing information, generating quotations, and managing production status are primarily performed manually and heavily dependent on the experience and skills of the workers; this is one of the major causes of reduced productivity and a lack of consistency in quality control.

[0004] Existing mold management systems primarily focus on individual functions, such as saving and sharing drawing files and requesting quotes, and have limitations in comprehensively managing and automating the entire mold manufacturing process. Furthermore, they lack the capability to systematically accumulate various data generated during the manufacturing process and optimize mold design and quotation processes based on this information. These limitations make it difficult for manufacturers to proactively eliminate uncertainties that may arise during production or to identify and respond to problems in real time.

[0005] Therefore, there is an urgent need for an integrated mold manufacturing management system that supports seamless information exchange between the client and the supplier, systematically manages the entire mold production process, and enables data-driven automated design and cost estimation. In particular, the introduction of a system capable of monitoring data from each stage of the mold manufacturing process in real time and supporting efficient decision-making based on this data can significantly contribute to simultaneously improving both the productivity and quality of mold production.

[0021] Hereinafter, in order to enable a person skilled in the art to easily practice the present invention, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0022] The embodiments of the present invention described below relate to a method and system for managing the entire mold manufacturing process. Hereinafter, the method for managing the entire mold manufacturing process may be briefly referred to as the “mold manufacturing management method,” and the system for managing the entire mold manufacturing process may be referred to as the “mold manufacturing management system.”

[0023] FIG. 1 is a schematic diagram showing the configuration of a mold manufacturing management system (1) according to an embodiment of the present invention. Referring to FIG. 1, the mold manufacturing management system (1) according to the present embodiment is composed of a mold manufacturing management server (10), an ordering company terminal (20), and a plurality of supplier terminals (30). The mold manufacturing management server (10), the ordering company terminal (20), and the plurality of supplier terminals (30) are connected to each other so as to be able to communicate through a communication network. At this time, the communication network can be configured regardless of the mode of communication, such as wired or wireless, and can be implemented in various forms so that communication between servers and between servers and between terminals is performed.

[0024] The mold manufacturing management server (10) creates and provides a mold manufacturing management platform (510) to the ordering company to support the ordering company in conveniently managing the mold manufacturing process of multiple parts, and processes various steps involved in mold manufacturing based on information received from the ordering company terminal (20) and the supplier terminal (30) through the mold manufacturing management platform (510), thereby enabling the ordering company to manage it easily. The specific configuration and operation of the mold manufacturing management server (10) will be explained in more detail below.

[0025] The ordering company terminal (20) is a terminal used by an ordering company that wants to manufacture molds. By accessing the mold manufacturing management platform (510) through the ordering company terminal (20), the ordering company can request the creation of a quotation for each part through the mold manufacturing management platform (510) and check the current progress status of each part at a glance.

[0026] Each supplier terminal (30) is a terminal used by a supplier that creates molds for each part at the request of the ordering company, and the supplier receives a request for a quote or a quote creation from the mold manufacturing management server (10) through the supplier terminal (30), and in response, can transmit quote information to the mold manufacturing management server (10) through the supplier terminal (30).

[0027] In this embodiment, the ordering company terminal (20) and the supplier terminal (30) may be one of various devices capable of communicating with the mold manufacturing management server (10), such as a smartphone, tablet, laptop, or desktop computer.

[0028] FIG. 2 is a configuration diagram of a mold manufacturing management server (10) according to an embodiment of the present invention. Referring to FIG. 2, the mold manufacturing management server (10) is composed of a processor (11), memory (12), a network unit (13), and a database (14).

[0029] The processor (11) is a type of central processing unit that controls the entire process related to the mold manufacturing management method. Each step performed by the processor (11) according to the present embodiment will be described later with reference to FIGS. 3 to 8. In the present embodiment, the processor (11) may include all types of devices capable of processing data. Here, 'processor' may refer to a data processing device embedded in hardware that has a physically structured circuit to perform a function expressed by code or instructions included in a program, for example. Examples of such data processing devices embedded in hardware may include microprocessors, central processing units (CPUs), processor cores, multiprocessors, ASICs (application-specific integrated circuits), FPGAs (field programmable gate arrays), etc., but the scope of the present invention is not limited thereto.

[0030] The memory (12) can store a program for the stage of the processor (11) and can also temporarily or permanently store input / output data.

[0031] The network section (13) may include wired / wireless internet modules for network access. Wireless internet technologies such as WLAN (Wireless LAN) (Wi-Fi), Wibro (Wireless broadband), WiMAX (World Interoperability for Microwave Access), and HSDPA (High Speed ​​Downlink Packet Access) may be used. Wired internet technologies such as XDSL (Digital Subscriber Line), FTTH (Fibers to the home), and PLC (Power Line Communication) may be used.

[0032] Various information related to the ordering company's mold manufacturing management is stored in the database (14). For example, the database (14) may store drawings of molds previously manufactured by the ordering company and information regarding at least one part included in the drawings of the molds. In addition, the database (14) may store the unit price of each part from multiple suppliers and the quality score of each supplier. The aforementioned components are exemplary and the scope of the present invention is not limited to the aforementioned components. That is, depending on the implementation mode of the embodiments of the present invention, additional components may be included or some of the aforementioned components may be omitted.

[0033] FIG. 3 is a flowchart of a mold manufacturing management method performed by a mold manufacturing management server (10) according to an embodiment of the present invention, and FIG. 5 is a drawing illustrating a mold manufacturing management platform (510) provided by a mold manufacturing management server (10) according to an embodiment of the present invention. Referring to FIG. 5, the mold manufacturing management platform (510) provided by the mold manufacturing management server (10) lists information regarding each part to be molded. For example, the mold manufacturing management platform (510) discloses various information related to the mold manufacturing of each part, such as the part number, part name, photo, drawing image, material, size, and current status information for each part. In this embodiment, the mold drawing may be a drawing of a single part, a drawing of a state in which multiple parts are combined, or a drawing of a state in which multiple parts are listed without being combined. Through this mold manufacturing management platform (510), the ordering company can conveniently grasp various information related to the mold manufacturing of each part at a glance.

[0034] Referring to FIG. 3, a mold manufacturing management method using a mold manufacturing management platform (510) is described. In step 301, the mold manufacturing management server (10) receives at least one mold drawing from the ordering company terminal (20) through the mold manufacturing management platform (510). The received mold drawing is posted on the mold manufacturing management platform (510) in a state where it can be downloaded.

[0035] In step 302, the mold manufacturing management server (10) obtains at least one part information corresponding to the mold drawing received from the ordering company terminal (20) in step 301. In this embodiment, the part information obtainable from the mold drawing includes various information related to mold manufacturing, such as the type, material, specifications, and tolerance of each part. The mold manufacturing management server (10) can obtain at least one part information corresponding to the mold drawing by receiving information about each part from the ordering company terminal (20) through the mold manufacturing management platform (510).

[0036] In step 303, the mold manufacturing management server (10) receives a request to generate a quotation for each part from the ordering company terminal (20) and, in response, transmits the request to generate a quotation for each part to each supplier terminal (30). The supplier that receives the request to generate a quotation for each part from the mold manufacturing management server (10) creates a quotation for each part and sends it back to the mold manufacturing management server.

[0037] In step 304, the mold manufacturing management server (10) transmits the quotation received from each supplier terminal (30) to the ordering company terminal (20). In another embodiment of the present invention, the mold manufacturing management server (10) may upload the quotation received from each supplier terminal (30) to the mold manufacturing management platform (510) by matching it to each part, thereby allowing the ordering company to check the quotation details for each part through the mold manufacturing management platform (510).

[0038] In step 305, the mold manufacturing management server (10) receives the supplier selection results for each part from the ordering company terminal (20). In this embodiment, the ordering company can select a supplier by accessing the mold manufacturing management platform (510) and selecting one of the multiple supplier quotations uploaded that are matched to each part. Then, in step 306, the mold manufacturing management server (10) can cause the selected supplier to start mold manufacturing by sending a notification requesting mold manufacturing to the supplier selected in step 305.

[0039] According to the mold manufacturing management method of the present embodiment, the entire mold manufacturing process of each part can be managed using the mold manufacturing management platform (510), making it very convenient.

[0040] Meanwhile, in another embodiment of the present invention, the mold manufacturing management server (10) can automatically perform a plurality of steps related to mold manufacturing. Referring to FIG. 4, in step 401, the mold manufacturing management server (10) receives a mold drawing from the ordering company terminal (20). The ordering company can provide the mold drawing to the mold manufacturing management server (10) by accessing the mold manufacturing management platform (510) and uploading the mold drawing.

[0041] In step 402, the mold manufacturing management server (10) obtains part information for at least one part from the mold drawing received in step 401. In this embodiment, the mold manufacturing management server (10) can automatically obtain part information from the received 2D drawing using artificial intelligence. More specifically, the mold manufacturing management server (10) can obtain information about each part included in the drawing by inputting the 2D drawing into an artificial intelligence model trained using multiple drawings containing key information such as various materials, tolerances, symbols, and guide lines as training data. The information about each part obtained in this way can be matched to the mold drawing and automatically input into the mold manufacturing management platform (510).

[0042] In step 403, the mold manufacturing management server (10) automatically generates an estimate based on the information of each part obtained in step 402. In this embodiment, the mold manufacturing management server (10) automatically generates an estimate based on the information of each part obtained in step 402 and the supply unit price table of each supplier stored in the database (14). The ordering party can request the generation of an estimate for each part by clicking the 'Generate Estimate' button (not shown) placed for each part on the mold manufacturing management platform (510). Of course, it is also possible to check at least some of the multiple parts and request the generation of estimates for the checked parts all at once.

[0043] FIG. 6(a) is a supply unit price table for each supplier stored in a database (14) according to an embodiment of the present invention. Referring to FIG. 6(a), a supply unit price table (610) is stored in the database (14) in which the supply unit price of each supplier for each part is matched. At this time, the supply unit price for each part may be the same or different depending on the supplier, and there may be parts for which molds cannot be made depending on the supplier. According to the supply unit price table (610) of FIG. 6(a), it can be seen that supplier B cannot supply molds for part c, and supplier D cannot supply part b. Meanwhile, FIG. 6(a) simply illustrates a supply unit price table (610) in which a single supply unit price is matched for each part for convenience of illustration, but it is also possible to form a supply unit price table (610) by matching detailed supply unit prices for multiple sizes and processes for each part.

[0044] In one embodiment of the present invention, the mold manufacturing management server (10) can extract the supply unit prices of multiple suppliers for each part from the supply unit price table (610) stored in the database (14), and generate an estimate by setting the average value of the extracted multiple supply unit prices as the estimated amount for the part. Referring to FIG. 6(b), which shows the estimated amount automatically calculated by the mold manufacturing management server (10) according to one embodiment of the present invention, the mold manufacturing management server (10) calculates the estimated amount for each part (a, b, c, d, e, f) that requires mold manufacturing, and it can be confirmed that the estimated amount for each part is set as the average value of the supply unit prices of each part listed in the supply unit price table (610). For example, it can be seen that the estimated price of part a is 460 won, which is the average of the supply unit prices of suppliers (A, B, C, D) supplying part a ((500+450+490+400) / 4), and the estimated price of part b is 350 won, which is the average of the supply unit prices of suppliers (A, B, C) supplying part b ((320+330+400) / 3). The mold manufacturing management server (10) can generate an estimate (710) showing the estimated price for each part determined in this way.

[0045] In this embodiment, the quotation (710) generated by the mold manufacturing management server (10) may include not only the quotation amount for each part, but also an input interface that allows each supplier to input whether to approve the quotation amount and the proposed price for each part, as shown in FIG. 7.

[0046] In step 404, the mold manufacturing management server (10) transmits the quotation generated in step 403 to each supplier terminal (30). Each supplier that receives the quotation from the mold manufacturing management server (10) reviews the quotation amount of each part in the received quotation through the supplier terminal (30) and inputs whether to supply the mold at the quotation amount of each part in the quotation through the input interface in the quotation.

[0047] At this time, if the supplier wishes to propose a different amount different from the quoted amount presented in the quote (710), it may send a quote response (810) regarding the quote to the mold manufacturing management server (10) by entering the proposed amount into the input interface. In this embodiment, if the mold manufacturing management server (10) has approved the supply for the quoted cost of a part in the quote response (810) received from the supplier terminal (30) but the proposed amount is not separately entered, it may be considered that the supplier has proposed the price as the quoted amount for that part. That is, for parts for which the supply was approved in the quote response (810) but the proposed amount is not entered, the mold manufacturing management server (10) determines that the supplier has entered the quoted amount as the proposed amount.

[0048] FIG. 8(a) is a drawing illustrating a quote response (810) sent to the mold manufacturing management server (10) by the supplier terminal (30) of supplier A. Referring to FIG. 8(a), supplier A did not approve the supply of part a, approved the supply of parts b and d by proposing 330 won and 120 won, respectively, which are lower than the quoted amount, and approved the supply of parts c, e, and f at the quoted amount on the quote sheet.

[0049] In step 405, the mold manufacturing management server (10) receives a quote response (810) from each supplier terminal (30) in response to the quote sent to each supplier terminal (30) in step 404, and can select a supplier to supply each part based on the received quote response (810).

[0050] In this embodiment, the mold manufacturing management server (10) obtains information on suppliers who have approved supply for each part from the quotation response (810) received from each supplier terminal (30), and then selects a supplier to manufacture and supply the mold for each part based on at least one of the proposed price and the quality score of each supplier. In this embodiment, the quality score is a value calculated based on the results of inspecting the mold of the part previously supplied by each supplier. The supplier has a higher quality score if the mold supplied by the supplier has no error compared to the design drawing and has a lower defect rate, and conversely, if the mold provided by the supplier has an error compared to the design drawing or has a high defect rate, it has a lower quality score. The quality score is information accumulated by continuously continuing transactions related to mold manufacturing with each supplier.

[0051] In one embodiment of the present invention, the mold manufacturing management server (10) can select a supplier to supply the mold for each part based on the price offered by the supplier in the quotation response (810). Specifically, the mold manufacturing management server (10) obtains information on suppliers who have approved the supply for each part, and among the suppliers who have approved the supply, the supplier with the lowest price offered can be selected as the supplier to supply the mold for the corresponding part. Accordingly, if four suppliers (A, B, C, D) all approved the supply for part d, but suppliers A, B, and C approved the supply at the quoted price, and supplier D approved the supply by offering a price lower than the quoted price, the mold manufacturing management server (10) can select supplier D as the supplier to supply the mold for part d (i.e., the supplier). If there are multiple suppliers that offered the lowest price, the mold manufacturing management server (10) can select the supplier with the higher quality score among them as the supplier to supply the mold for the corresponding part.

[0052] In another embodiment of the present invention, the mold manufacturing management server (10) can select a supplier to supply the mold for each part based on the quality score of each supplier. Specifically, the mold manufacturing management server (10) can obtain information on suppliers who have approved the supply for each part and select the supplier with the highest quality score among the suppliers who have approved the supply as the supplier to supply the mold. Accordingly, when four suppliers (A, B, C, D) all approve the quoted amount for part d, regardless of the amount proposed by each supplier, the supplier with the highest quality score can be selected as the supplier to supply the mold for part d by comparing the quality scores of each supplier.

[0053] In another embodiment of the present invention, the mold manufacturing management server (10) can select a supplier to supply molds for each part based on the price offered by the supplier and the quality score of each supplier in the quotation response (810). Specifically, the mold manufacturing management server (10) can obtain information on suppliers that have approved the supply of each part and normalize the price offered and the quality score of each supplier that has approved the supply. At this time, the mold manufacturing management server (10) normalizes the price offered so that the higher the price offered by the supplier for each part, the closer the value is to 0, and the lower the price offered, the closer the value is to 1, and normalizes the quality score so that the lower the quality score of the supplier, the closer the value is to 0, and the higher the quality score, the closer the value is to 1.

[0054] Subsequently, the mold manufacturing management server (10) assigns weights to the normalized proposed price and quality score, and can select a supplier with a high weighted sum as the supplier to supply the mold for the corresponding part. In this embodiment, the weights of the proposed price and quality score can be set by the ordering company. For example, an ordering company that prioritizes a lower price over quality may set a high weight for the proposed price and a low weight for the quality score. On the other hand, an ordering company that prioritizes quality over price may set a high weight for the quality score and a low weight for the proposed price.

[0055] In an embodiment of the present invention, when a supplier to supply molds for each part is selected, the mold manufacturing management server (10) updates the supply unit price table (610) stored in the database (14) so ​​that the amount proposed by the selected supplier in the quotation response (810) for the part becomes the supply unit price of the supplier for the part.

[0056] For example, in step 405, if Supplier A is selected as the supplier to supply the molds for parts b and c, the supplier unit price table (610) is updated as shown in FIG. 8(b). Referring to FIG. 8(b), it can be seen that in the unit price table (610), Supplier A’s unit price for part b is updated to 330 won, which is what Supplier A proposed for part b in the quotation response (810), and Supplier A’s unit price for part c is updated to 490 won, which is the amount approved by Supplier A in the quotation response (810). Supplier A’s unit price for parts a, d, e, and f remains unchanged because Supplier A was not selected as the supplier for parts a, d, e, and f. The unit prices of the remaining suppliers selected to supply parts a, d, e, and f are updated in the same manner.

[0057] In this way, the mold manufacturing management server (10) provides a quotation (710) capable of presenting prices for each part through a quotation response (810) to each supplier terminal (30), selects a mold supplier based on the amount presented by the supplier, and obtains the latest price information of each supplier by reflecting the amount of the selected supplier in the supply unit price table of the database (14) and updating it as a supply unit price for each part, and by calculating the quotation amount of the next quotation based on this latest information, a reasonable quotation can be dynamically generated.

[0058] The mold manufacturing management server (10) requests the supplier terminal (30) of each selected supplier to manufacture and provide the mold for each part.

[0059] In step 406, the mold manufacturing management server (10) inspects the molds of each part received from each supplier selected in step 405. In this embodiment, the inspection of the molds by the mold manufacturing management server (10) can be performed by an artificial intelligence model. For example, the mold manufacturing management server (10) can inspect external defects of the mold (e.g., scratches, cracks, etc.) using a computer vision model such as YOLO or Faster R-CNN, verify information (numbers, symbols, etc.) engraved on the surface of the mold using OCR (Optical Character Recognition) such as EasyOCR or Tesseract, and compare dimensions and tolerances based on 3D data.

[0060] More specifically, the mold manufacturing management server (10) first acquires 2D or 3D scan data of the mold to inspect the mold received from each supplier. This scan data is digitized data representing the overall characteristics of the mold, including its external shape, dimensions, tolerances, and material, and the mold manufacturing management server (10) can inspect the quality of the mold by inputting this into an artificial intelligence model. In this embodiment, the mold manufacturing management server (10) utilizes computer vision technology to detect external defects of the mold, identifies the location and type of defects such as scratches, cracks, and deformation based on the scan data, and evaluates the design suitability of the mold by comparing it with reference design data. Additionally, the mold manufacturing management server (10) compares the 3D scan data with a reference design drawing to verify the dimensions and tolerances of the mold, and confirms the suitability of the dimensions by detecting areas that exceed the tolerance range. In the case of material verification, the mold sample is analyzed or component data regarding the mold material is collected, and then processed by an artificial intelligence model to evaluate whether the analysis result matches the reference specifications.

[0061] The mold manufacturing management server (10) synthesizes these inspection results to determine a quality score for each supplier. The quality score determined in this way can be considered as a selection factor along with the supply unit price of each supplier obtained from the supply unit price table (610) when selecting a supplier later. In addition, the mold manufacturing management server (10) posts these inspection results on the mold manufacturing management platform (510) so that the ordering company can check the inspection results for each supplier.

[0062] The status of each production stage performed by the mold production management server (10) according to the present embodiment can be reflected in the mold production management platform (510) in real time. For example, if the mold production management server (10) has currently generated a quotation for each part and sent it to each supplier, it can display a 'waiting for quotation response' indicator on the mold production management platform (510) in real time by matching it to each part; if a supplier has been selected and the supplier is producing the part, it can display a 'waiting for receipt' indicator. Through this, the ordering company can easily identify and manage all stages related to mold production.

[0063] Meanwhile, according to the present embodiment, data accumulated in the mold manufacturing management platform generated by the mold manufacturing management server (10) may be used to increase the efficiency of mold manufacturing and management. More specifically, the mold manufacturing management platform (510) can automatically classify new drawing files uploaded from the ordering company and automatically extract basic information such as part number, material, dimensions, and tolerances of each part from the drawing through OCR technology. The information extracted in this way is compared with the data of the existing system stored in the database (14), and the mold manufacturing management server (10) can review the accuracy of the information extraction results and reflect them in the mold manufacturing process.

[0064] In addition, when a request for mold production for multiple parts is made by an ordering company, the mold production management platform (510) reduces the burden of manual input by workers and supports the automation of drawing information and the process of generating estimates. For example, the mold production management server (10) generates an estimate for each part based on information extracted from the drawing, and the generated estimate is exchanged between the ordering company and the supplier through the platform. This prevents input errors by workers and reduced work efficiency that repeatedly occurred in existing systems.

[0065] In addition, the mold manufacturing management platform (510) can support the generation of basic layout design documents required for mold manufacturing based on existing drawing data and extracted key information. According to this embodiment, the mold manufacturing management server (10) can automatically generate basic data for layout design and process design required in the mold design process using the extracted key information, and store this in a database so that it can be utilized in the future mold manufacturing process. In this process, the burden of repetitive work on mold manufacturing experts can be reduced, and errors that may occur during the mold design process can be minimized.

[0066] In conclusion, the mold manufacturing management platform (510) of the present invention can be used to efficiently manage information exchange and work processes related to mold manufacturing between the ordering company and the supplier, and to increase the accuracy and efficiency of the overall mold manufacturing process through data-based automated design and quotation.

[0067] Additionally, the mold manufacturing management server (10) can generate an alarm if necessary at each stage of mold manufacturing for each part being carried out through the mold manufacturing management platform (510). More specifically, the mold manufacturing management server (10) stores a threshold period for each stage in advance, and can generate an alarm to the stage performer if each stage is longer than the threshold period. For example, if the mold manufacturing management server (10) maintains a 'waiting for quotation response' status for a certain part for more than one week, it can automatically send a reminder alarm requesting the supplier terminal (30) of the supplier that received the quotation but has not yet replied to the quotation response to send the quotation response.
