Description

Technical Field

[0001] The present application relates to the field of trial mold tracking technology, and in particular to a trial mold tracking system. Background Art

[0002] Mold trial is a key step in verifying whether the mold design and production process are reasonable. By tracking mold trial data, design and process defects can be quickly discovered to prevent unqualified molds from entering the mass production stage. Traditional mold trial tracking methods rely on manual records or paper forms, which are prone to handwriting errors or data loss. Therefore, this application proposes a mold trial tracking system.

[0003] The prior art, such as the invention application patent with announcement number: CN119526545A, discloses a concrete test block mold, a demoulding device and a demoulding production line, wherein the concrete test block mold includes a membrane box, a pinhole is provided at the bottom wall of the membrane box, and the pinhole passes through the bottom wall of the membrane box, the demoulding device includes a base, a positioning block matching the positioning groove and a positioning seam matching the positioning edge is provided on the top of the base, a pin is provided at the center of the top of the positioning block, and a plurality of ventilation holes are provided around the top of the positioning block, an air compressor connected to the ventilation hole is provided in the base, and the demoulding production line includes a control center, a transfer robot, a demoulding device, a static rack, a mold conveyor belt and a coding workstation. This application has the effect of improving the demoulding quality of the test block.

[0004] Existing technology, such as the invention patent application with publication number CN110705826A, discloses a method and system for tracking and managing construction quality using QR codes. This method aims to address the technical problem that existing construction control systems can only access data in the control room, and cannot provide real-time information on construction status and responsible personnel when problems arise at the construction site or after construction is completed. The key points of the technical solution are: Step S1: Divide the area, establish a corresponding database based on the construction scope, and pre-enter the construction status; Step S2: Generate a QR code pointing to the corresponding area database using a QR code generator and post it for public display; Step S3: The construction party scans the corresponding QR code according to the public display to obtain the construction area and carry out the corresponding construction, then writes the construction information into the database; Step S4: The quality inspection party conducts quality inspection and acceptance of each area and records the quality inspection information in the database. This achieves the effect of being able to understand the status of construction personnel by scanning QR codes at the construction site, facilitating timely accountability when problems arise at the construction site.

[0005] The above solution has the following technical problems: 1. The current technology mainly considers the demoulding quality of the test block, but does not take into account that when the number of molds is large, the number of test blocks produced will also be large. At this time, the test blocks produced by each mold may be mixed up due to improper management, which will affect the subsequent analysis of the mold production situation.

[0006] 2. Current technology does not consider quality analysis of each test block produced based on each mold, and thus does not consider the quality of each test block to reflect the production quality of each mold. When each mold is subsequently put into mass production, different molds are selected based on the requirements of the production order. The current technology's neglect of this aspect may lead to the inability to accurately detect the production quality of the mold, thereby affecting the quality of subsequent products. Summary of the Invention

[0007] The purpose of this application is to provide a trial mold tracking system that solves the problems existing in the background technology.

[0008] In order to solve the above technical problems, the present application adopts the following technical solutions: The present application provides a trial mold tracking system, including: a QR code generation module, a QR code printing module, a trial mold tracking module and an order matching module.

[0009] QR code generation module: used to number each mold and obtain the working parameters of each mold from the control center, generate a QR code for each mold based on the number and working parameters of each mold, and after the production of each test block is completed, generate a QR code for each test block based on the production information of each test block.

[0010] QR code printing module: used to spray code on each mold and each test block, and trace the information of each mold and each test block through scanning traceability software.

[0011] Test mold tracking module: used to analyze the performance defect parameters of each test block, and then analyze and obtain the production defect parameters of each mold, and grade each mold based on the production defect parameters of each mold, and update the QR code information of each test block and each mold based on the performance defect parameters of each test block and the production defect parameters and grading information of each mold.

[0012] Order matching module: used to obtain product parameters in each production order from the production center, and then classify each production order, so as to match each production order with each mold.

[0013] The beneficial effects of this application are: 1. The present application provides a test mold tracking system, which generates a QR code for each mold based on the number and working parameters of each mold, prints and posts it on the outer layer of each mold, and then generates a QR code for each test block based on the production information of each test block, and sprays it on the surface of each test block, thereby effectively avoiding data falsification and handwriting errors or data loss caused by traditional manual records or paper forms, effectively improving data authenticity. At the same time, it is equipped with code scanning and traceability software to view the test block information in real time, and finally classifies the molds corresponding to the defect information of each test block. After each mold is put into the production line, the molds at each level are matched according to the production requirements of each production order, effectively improving production flexibility and convenience.

[0014] 2. This application obtains the working parameters and numbers of each mold from the control center, and obtains the production information of each test block after each test block is demolded, laying the foundation for subsequent test mold tracking. Then, based on the working parameters and numbers of each mold, a QR code of each mold is generated, affixed to the outer layer of each mold, and the QR code of each test block is sprayed on the surface of each test block through a QR code printing system. Each test block has the same QR code as the corresponding mold. This can effectively avoid data falsification and improve data authenticity. It can also scan the QR code through the code scanning and traceability software to accurately track the information of each test block and each mold in real time, thereby improving the convenience and accuracy of test mold tracking and avoiding manual records or paper form records, which are prone to handwriting errors or data loss.

[0015] 3. This application analyzes the performance defects of each test block produced by each mold, and further analyzes the production defects of each mold. Based on this, the QR code of each mold and each test block is updated to ensure the accuracy and timeliness of the data. At the same time, each mold is graded based on its production defects. When each mold is put into mass production, the appropriate mold is matched according to the requirements of the production order, which ensures the production rate while also ensuring the production quality, which is beneficial to the long-term development of the factory.

Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0017] Figure 1 This is a schematic diagram of the system structure connection for this application. DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] Reference Figure 1 As shown, the present application provides a trial mold tracking system, which includes the following modules: a QR code generation module, a QR code printing module, a trial mold tracking module and an order matching module.

[0020] QR code generation module: used to number each mold and obtain the working parameters of each mold from the control center, generate a QR code for each mold based on the number and working parameters of each mold, and after the production of each test block is completed, generate a QR code for each test block based on the production information of each test block.

[0021] In a specific example, the working parameters of each mold include structural parameters, process parameters, material parameters and precision parameters. The structural parameters include dimensional parameters and mechanical parameters; the process parameters include the mold's tolerable temperature range, pressure range, speed range and time range; the material parameters include mold materials and various machinable materials.

[0022] It should be noted that the dimensional parameters include the mold cavity size, template size and draft angle; the mechanical parameters include mold weight, mold force and ejector stroke; the precision parameters include the mold cavity surface roughness and the dimensional error threshold of the mold corresponding test block.

[0023] In a specific example, the production information of each test block includes basic information and process information of each test block, and the basic information includes the production batch of each test block and the corresponding mold; the process information includes basic attribute parameters and production process, and the basic attribute parameters include geometric parameters and materials.

[0024] It should be noted that the materials of the test blocks include metal materials, polymer materials, composite materials or ceramic and glass materials, etc.; the production processes include slip casting, melt molding or autoclave molding, etc.

[0025] In a specific example, the process of generating the QR code of each test block based on the production information of each test block is as follows: first, a unique QR code corresponding to each mold is generated based on the number and working information of each mold.

[0026] The corresponding test blocks are placed in the mold and demolded after each test block is formed. At the same time, a QR code printing system is equipped. After each test block is demolded, the QR code printing system generates a QR code corresponding to each test block based on the QR code of the mold corresponding to each test block and the production process information of each test block. The QR code of each test block is the same as the QR code of the corresponding mold.

[0027] It should be noted that the "one code, multiple connections" model of using the same QR code for the test block and the corresponding mold not only solves the problems of inefficient traceability and chaotic data management, but also saves data storage space.

[0028] QR code printing module: used to spray code on each mold and each test block, and trace the information of each mold and each test block through scanning traceability software.

[0029] In a specific example, the coding of each mold and each test block is performed in the following specific process: for each mold, the staff prints out the QR code of each mold and sticks it on the outer layer of each mold.

[0030] For each test block, the QR code printing system automatically identifies the production process of each test block. When it is identified that each test block has been demolded, the QR code printing system obtains the size of each test block identified, reduces the size of each test block according to a preset ratio to obtain the QR code size of each test block, and sprays the QR code on the outer layer of each test block based on the QR code size corresponding to each test block. At the same time, the QR code printing system generates a unique UID for each test block and sprays the UID of each test block under the QR code. The QR code of each test block is the same as the QR code of the corresponding mold, but the information queried after scanning the code is different.

[0031] It should be noted that the QR code printing system adjusts the QR code size according to the size of each test block, ensuring the flexibility of the test mold tracking system.

[0032] It should be noted that the preset ratio is set by relevant staff. For example, it can be 50% of the test block size, 60% of the test block size, or 70% of the test block size. No specific limitation is made here.

[0033] In a specific example, the code scanning and traceability software performs information traceability on each mold and each test block. The specific process is as follows: when the staff scans the QR code on the outer layer of each mold and each test block through the code scanning and traceability software, the staff can choose to view the mold information or the test block information. When the staff chooses to view the mold information, the code scanning and traceability software displays the relevant information number and working parameters of the corresponding mold.

[0034] When the staff chooses to view the test block information, they need to enter the UID of the relevant test block. After successful input, the traceability software will display the relevant information of the corresponding test block. If the input is incorrect, it will prompt you to re-enter.

[0035] Test mold tracking module: used to analyze the performance defect parameters of each test block, and then analyze and obtain the production defect parameters of each mold, and grade each mold based on the production defect parameters of each mold, and update the QR code information of each test block and each mold based on the performance defect parameters of each test block and the production defect parameters and grading information of each mold.

[0036] It should be noted that the performance defect parameters of each test block include the geometric parameter error, defect quantity and quality error of each test block; the production defect parameters of each mold include the geometric parameter error, production defect quantity and production quality error growth value of each mold.

[0037] In a specific example, the performance defect parameters of each test block are analyzed, and then the production defect parameters of each mold are analyzed. The specific process is as follows: first, the geometric parameters of each test block are detected, and the standard values ​​of the geometric parameters corresponding to each test block are obtained based on the production specification table, and then the geometric parameter errors of each test block are calculated, and the average value of the geometric parameter errors of each test block produced by each mold is statistically calculated, and the average value of the geometric parameter errors of each test block produced by each mold is recorded as the geometric parameter error corresponding to each mold.

[0038] It should be noted that the average value of the difference between the geometric parameters of a test block and the standard value of the geometric parameters of the test block is recorded as the geometric parameter error of the test block, and the geometric parameter error of each test block is obtained based on this.

[0039] Then, an industrial camera is used to collect images of each test block, and the number of defects of each test block is obtained through image processing technology. The average number of defects of each test block produced by each mold is calculated, and the average number of defects of each test block produced by each mold is recorded as the production defect number corresponding to each mold.

[0040] It should be noted that the industrial cameras include high-precision area array CCD / CMOS cameras, line array cameras and multi-camera vision systems.

[0041] It should be noted that the number of defects of each test block is obtained by image processing technology. First, the test block is placed in the detection area, and the camera distance is adjusted to ensure that the test block occupies at least 70% of the screen. The camera is triggered to capture the test block image, and then the captured test block image is preprocessed, including denoising, grayscale conversion and image enhancement. The defect features of the preprocessed test block image are then extracted through steps such as edge detection and threshold segmentation. Finally, the number of defects is counted through a defect recognition algorithm and the defect number data is output. Among them, denoising, grayscale conversion, image enhancement, edge detection, threshold segmentation and defect recognition algorithms are all existing technologies and will not be repeated here.

[0042] It should be noted that the defects of the test block include gaps and bubbles.

[0043] At the same time, after each mold continuously produces several test blocks, a high-precision measuring instrument is used to measure the quality parameters of each test block, and the standard value of the quality parameters of each test block is obtained based on the production specification table, and then the quality error of each test block is calculated, and the production quality error growth value corresponding to each mold is calculated.

[0044] It should be noted that the average value of the difference between the quality parameter of a test block and the standard value of the quality parameter corresponding to the test block is recorded as the mass error of the test block, and the mass error of each test block is obtained based on this.

[0045] It should be noted that due to mold wear, tiny debris will be generated and attached to the test block, and the test block material will have additional loss due to mold wear, which will lead to changes in the quality of the test block. Therefore, testing the quality of the test block can analyze the wear of the mold.

[0046] In a specific example, the molds are graded based on the production defect parameters of each mold. The specific analysis process is as follows: the production defect parameters of each mold are normalized and recorded as , where K is the number of each mold, k is a positive integer, m is the number of each production defect parameter, m=1, 2, 3, where number 1, number 2, and number 3 represent the geometric parameter error, number of production defects, and production quality error growth value of the mold, respectively. Substitute the production defect parameters of each mold into the mold grade evaluation module, according to the mold grade evaluation model expression: Output the working performance characteristic value of the mold numbered k , where M is the total number of performance parameters of the mold, M=3, is the weight factor corresponding to the performance parameter numbered m, and They represent the first-class threshold and second-class threshold of the mold working performance evaluation coefficient respectively.

[0047] When the performance characteristic value is 1, it indicates that the mold performance is good, and each mold with a performance characteristic value of 1 is recorded as a first-level mold. When the performance characteristic value is 0, it indicates that the mold performance is average, and each mold with a performance characteristic value of 0 is recorded as a second-level mold. When the performance characteristic value is -1, it indicates that the mold performance is poor, and each mold with a performance characteristic value of -1 is recorded as an unqualified mold.

[0048] It should be noted that the first-class threshold and the second-class threshold of the mold performance evaluation coefficient are both obtained by consulting the production instructions of the mold.

[0049] It should be noted that the weight factors of the performance parameters are obtained by analyzing the hierarchical analysis method, and the weight factors of the performance parameters are obtained by building a hierarchical structure, constructing a judgment matrix, consistency testing and weight calculation. The hierarchical analysis method is an existing technology and will not be described in detail.

[0050] It should be noted that production orders are matched for each mold according to its grade. For example, first-level molds are used to produce high-value-added products and large-scale stable production, and are preferentially equipped with automated testing equipment. Second-level molds are suitable for conventional products and are regularly calibrated for precision and undergo preventive maintenance.

[0051] It should be noted that defects in each unqualified mold are repaired. Geometric parameter defects are repaired through mechanical processing, electrospark machining and other methods, among which mechanical processing includes grinding, milling and boring. For the number of production defects and production quality errors, surface treatment technology is used to repair defects, among which surface treatment technology includes chrome plating, nickel plating, nitriding and laser cladding. For example, when the die-casting mold is worn, chrome plating is used to improve wear resistance and demoulding properties. After defect repair and completion, each unqualified mold is re-tested to ensure the quality of each mold and reduce the waste of mold materials.

[0052] Order matching module: used to obtain product parameters in each production order from the production center, and then classify each production order, so as to match each production order with each mold.

[0053] It should be noted that the product parameters include the geometric parameter error threshold, the allowable defect quantity threshold and the allowable quality error threshold of the product in each production order.

[0054] In a specific example, the classification of each production order is as follows: the product parameters in each production order are normalized and recorded as , where i is the number of the production order, i is a positive integer, j is the number of each product parameter, j = 1, 2, 3, number 1, number 2 and number 3 represent the geometric parameter error threshold, the allowable defect number threshold and the allowable quality error threshold respectively. Substitute the product parameters in each production order into the product grade evaluation model, and the product grade evaluation model expression is: Output product grade characteristic values ​​in each production order , where J is the total number of production orders, J=3, is the threshold of the product performance evaluation coefficient, is the weight factor corresponding to the product parameter numbered j; It should be noted that the threshold of the product performance evaluation coefficient is set by the relevant staff. For example, the threshold of the product performance evaluation coefficient of each production order can be normally distributed, and the middle value after the normal distribution can be used as the threshold of the product performance evaluation coefficient. No specific restrictions are made here.

[0055] It should be noted that the setting method of the weight factor corresponding to the product parameter numbered j is the same as the setting method of the weight factor corresponding to the performance parameter numbered m, so it will not be repeated here.

[0056] When the product grade characteristic value is 1, it indicates that the production requirements of the product are high, and each production order with a product grade characteristic value of 1 is recorded as a Class I order. When the product grade characteristic value is -1, it indicates that the production requirements of the product are average, and each production order with a product grade characteristic value of -1 is recorded as a Class II production order.

[0057] In a specific example, the matching of each production order with each mold is specifically represented by using each first-level mold to produce each type of production order, and using each second-level mold to produce each type of production order.

[0058] It should be noted that each mold is tested according to a preset cycle, and then each mold is re-graded in each preset cycle to ensure the quality of the products produced by each mold.

[0059] The present application provides a test mold tracking system, which generates a QR code for each mold according to the number and working parameters of each mold, prints and posts it on the outer layer of each mold, and then generates a QR code for each test block according to the production information of each test block, and sprays it on the surface of each test block, thereby effectively avoiding data falsification and handwriting errors or data loss caused by traditional manual records or paper forms, effectively improving data authenticity. At the same time, it is equipped with code scanning and traceability software to view the test block information in real time, and finally classifies the molds corresponding to the defect information of each test block. After each mold is put into the production line, the molds at each level are matched according to the production requirements of each production order, effectively improving production flexibility and convenience.

[0060] The above content is merely an example and explanation of the concept of the present application. Technicians in this technical field may make various modifications or additions to the described specific embodiments or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined in this application, they should all fall within the scope of protection of this application.
