Description

[0001] Divisional application

[0002] The present application is a divisional application of the application with the application number 202410918540.1 and the title of "A intelligent parameter adjusting method and system for injection molding equipment, storage medium and program product" filed on July 5, 2024. TECHNICAL FIELD

[0003] The present application belongs to the technical field of injection molding equipment parameter adjustment, and particularly relates to a method and system for adjusting injection molding equipment process parameters based on historical data, and a storage medium. BACKGROUND

[0004] With the increasing richness of plastic products, the process requirements for injection molding processing are also continuously improved. A set of specific injection molding molds cannot meet the needs of production and processing for a single injection molding machine. Considering the universality, a single injection molding machine usually needs to be matched with multiple sets of injection molding molds, and different injection molding molds are used for processing according to different production and processing tasks arranged. However, different injection molding molds have different requirements for injection molding process parameters of the injection molding machine. A specific injection molding mold needs to be matched with specific injection molding process parameters such as injection speed, pressure and specific mold clamping force of the injection molding machine, so as to ensure that the molding precision of the product meets the processing requirements.

[0005] The existing parameter adjusting method is to adjust the equipment one by one by manual operation, which reduces the starting rate and processing rate on the one hand, and on the other hand, if the process parameters are found through trial production for each device, that is, the process standard parameters for producing good products are found through trial and error, which leads to more material waste and higher cost.

[0006] In addition, different equipment combinations may produce different injection molding products, so once the product is changed, it may need to be designed and adjusted again, which undoubtedly further increases the cost. Moreover, it is heavily dependent on manual experience. SUMMARY

[0007] The purpose of the present application is to provide a method and system for adjusting process parameters based on historical data, and a computer readable storage medium, which can match appropriate production equipment combinations and process parameters according to historical data.

[0008] In order to solve the above-mentioned technical problems, the present application specifically adopts the following technical solutions:

[0009] The first aspect of the present application is to provide a method for adjusting process parameters based on historical data, comprising:

[0010] Based on the production equipment combination and process parameters corresponding to the production of different injection molding products in the previous production process, a device pool and a standard process parameter pool are constructed; the production equipment combination includes an injection molding machine and several auxiliary equipment; the injection molding product is marked as a qualified injection molding product;

[0011] According to the type of injection molding product and the key parameters of the injection molding machine to be adjusted, several groups of production equipment combinations consistent with the key parameters are selected from the device pool as candidates, and one of them is recommended as the best production equipment combination; the key parameter is the tonnage of the injection molding machine;

[0012] The process parameters for producing the type of injection molding product by the best production equipment combination are matched from the standard process parameter pool, and the process parameters are updated to the injection molding machine to be adjusted and auxiliary equipment.

[0013] As an improvement, for the same injection molding product, the device pool includes a plurality of production equipment combinations whose batch quantity of historical processing of the same injection molding product is greater than a preset quantity threshold, and the average yield reaches a preset yield threshold;

[0014] Among them, when one of them is recommended as the best production equipment combination, according to the preset production plan, the total number of production batches, the total output and the preset yield of the current injection molding product to be produced are obtained, from the several groups of production equipment combinations selected as candidates, the historical production batch quantity and its historical total output are greater than or equal to the total number of production batches and its total output, and the average product yield is greater than or equal to the preset yield, then a production equipment combination is randomly selected from them as the best production equipment combination;

[0015] Based on the standard process parameter pool of the best production equipment combination, run once, and determine whether the injection molding product obtained by running is a qualified product, if not, re-match the best production equipment combination; if it is a qualified product, run a production batch or a preset number of times, and obtain the corresponding actual product yield;

[0016] Determine whether the actual product yield reaches the preset yield, if not, select one of the production equipment combinations with the highest average yield as the best production equipment combination.

[0017] As an improvement, in the case that the user does not accept the auxiliary equipment in the best production equipment combination, other auxiliary equipment is recommended from the candidate production equipment combination until the user accepts or the candidate production equipment combination recommendation is exhausted, or the user configures auxiliary equipment to form a new best production equipment combination.

[0018] As an improvement, if no production equipment combination is matched with the historical production batch quantity and its historical total output greater than or equal to the production batch total quantity and its total output, and the average product yield greater than or equal to the preset yield, at least one production equipment combination with the average product yield greater than or equal to the preset yield in the specified time period is matched, and the production equipment combination with the maximum average yield is selected as the best production equipment combination.

[0019] As a further improvement, for each injection molding product, the ratio of the number of times each production equipment combination is adopted to the number of times it is recommended is calculated as its reference index, and when a plurality of production equipment combinations with the historical production batch quantity and its historical total output greater than or equal to the production batch total quantity and its total output, and the average product yield greater than or equal to the preset yield are screened from the plurality of groups of production equipment combinations, the production equipment combination with the maximum reference index is selected as the best production equipment combination.

[0020] As an improvement, an identification is provided on the injection molding product, which contains the quality inspection result, the production equipment combination for producing the injection molding product, and the corresponding process parameters.

[0021] As an improvement, the identification is a two-dimensional code, and the information contained in the two-dimensional code can only be scanned out by a specific APP.

[0022] As an improvement, a data collector is used to collect the process parameters of the production equipment combination in the process of producing the injection molding product, and the production equipment combination and the process parameters for producing the qualified injection molding product are used to construct the device pool and the standard process parameter pool.

[0023] As an improvement, the key parameter is the tonnage of the injection molding machine.

[0024] The second aspect of the present application provides a parameter adjustment system based on historical data for adjusting process parameters, comprising:

[0025] A data construction module is used to construct a device pool and a standard process parameter pool based on the production equipment combinations and the process parameters corresponding to different injection molding products in the previous production process; the production equipment combination includes an injection molding machine and a plurality of auxiliary equipment; the injection molding product is marked as a qualified injection molding product;

[0026] A recommendation module is used to select a plurality of groups of production equipment combinations consistent with the key parameters of the injection molding product type and the injection molding machine to be adjusted as candidates in the device pool, and recommend one group as the best production equipment combination;

[0027] A parameter matching module is used to match the process parameters for producing the injection molding product of the type from the standard process parameter pool for the best production equipment combination, and update the process parameters to the injection molding machine to be adjusted and the auxiliary equipment.

[0028] The configuration module is configured to configure the auxiliary equipment by the user to form a new optimal production equipment combination when the user does not accept the auxiliary equipment in the optimal production equipment combination.

[0029] When the recommendation module recommends one of the groups as the optimal production equipment combination, the production batch number and the historical total output of the historical production batch are greater than or equal to the production batch total number and the total output, and the average product yield is greater than or equal to the preset yield, a plurality of production equipment combinations are selected from the plurality of groups of production equipment combinations, and then one of the production equipment combinations is randomly selected as the optimal production equipment combination; and when the injection molding product obtained by running the standard process parameter pool based on the optimal production equipment combination once is a qualified product, and the actual product yield obtained by running a production batch or a preset number of times again does not reach the preset yield, one of the production equipment combinations with the largest average yield is selected as the optimal production equipment combination.

[0030] As an improvement, the recommendation module recommendation is also used when no production equipment combination is matched, the number of historical production batches and the historical total output of which are greater than or equal to the production batch total number and the total output, and the average product yield is greater than or equal to the preset yield, to match at least one production equipment combination with an average product yield greater than or equal to the preset yield in a specified time period, and to select one of the production equipment combinations with the largest average yield as the optimal production equipment combination.

[0031] The third aspect of the present application provides a storage medium, the storage medium stores a computer program, the computer program is executed to implement the intelligent parameter adjustment method of the injection molding equipment.

[0032] The fourth aspect of the present application provides a computer system, including a processor and a memory, the memory stores a computer program, the computer program is executed to implement the intelligent parameter adjustment method of the injection molding equipment.

[0033] The advantages of this invention are as follows: This invention constructs an equipment pool and a standard process parameter pool based on historical data showing the production of qualified injection-molded products (or good products). When debugging newly purchased equipment, the key parameters of the injection molding machine and the type of injection-molded product are automatically matched from the standard process parameter pool to the process parameters for producing the corresponding qualified injection-molded products, automatically adapting them to the new injection molding equipment and its auxiliary equipment without manual parameter adjustment. Furthermore, during the equipment configuration stage, several production equipment combinations can be selected from the equipment pool for recommendation based on the key parameters of the injection molding machine and the type of injection-molded product. If the user accepts the recommendation, the corresponding process parameters are matched from the standard process parameter pool and synchronized to the corresponding production equipment combination. If the user does not accept the recommendation, production equipment combinations can continue to be recommended, or the user can configure auxiliary equipment matching the injection molding machine to form a production equipment combination. The corresponding process parameters are matched from the standard process parameter pool based on the user's self-configured production equipment combination and synchronized to the corresponding production equipment combination.

[0034] Furthermore, this invention incorporates QR codes on injection-molded products for digital traceability, thereby linking the injection-molded product with the production equipment, corresponding process descriptions, and quality assessments. The information obtained from these QR codes can only be scanned via a dedicated app, protecting the manufacturer's trade secrets.

[0035] The parameter tuning method of the present invention does not require complex means such as building models. It relies on historical data to match the corresponding equipment and parameters, which is simple and fast and applicable to the injection molding field. Attached Figure Description

[0046] The prior art CN115146875A discloses a process parameter recommendation method, device, system and medium based on historical data. In a specific embodiment, the method comprises: based on the current material attribute, retrieving historical data about the mapping relationship between the material attribute and the process parameter, obtaining the recommended process parameter corresponding to the historical material attribute closest to the current material attribute; taking the recommended process parameter as the optimization starting point, adjusting the process parameter based on the trained regression model until the local optimal process parameter satisfying the expected measurement result is obtained.

[0047] The prior art adjusts the process parameters by establishing a regression model to obtain the optimal process parameters. This method has high professional degree and is difficult to implement because a model needs to be established. In addition, in the field of injection molding technology, different equipment combinations can produce the same product, and the same equipment combination (except for the mold) can produce different products. Therefore, for the same product, different equipment combinations and process parameters can be selected.

[0048] Example 1: In order to adapt to the parameter adjustment of the injection molding equipment, as shown in the following table, the present application provides a method for adjusting the process parameters of the injection molding equipment based on historical data, comprising: Figure 1

[0049] S101, based on the production equipment combination and process parameters corresponding to the production of different injection molding products, a device pool and a standard process parameter pool are constructed; the production equipment combination includes an injection molding machine and several auxiliary equipment.

[0050] Specifically, in the previous production process, the data collector is used to collect the process parameters of the production equipment combination in the production of injection molding products, and the production equipment combination and the process parameters when the qualified injection molding products are produced are used to construct the device pool and the standard process parameter pool. The qualified injection molding products can be approved by quality inspection or by customers.

[0051] For example, the injection molding machine and auxiliary equipment such as mold temperature machine, temperature control box, etc. used to produce a certain injection molding product are recorded, and their model types such as tonnage, power, etc. are recorded at the same time, and the process parameters such as pressure, temperature, time, etc. in the production process are collected. If the injection molding product is finally determined to be qualified, the above recorded data is added to the device pool and the standard process parameter pool.

[0052] Generally, for the same injection molding product and the same set of production equipment combination, after adjustment, the production equipment will run under the same set of process parameters unless the equipment fails or the injection molding product is replaced, the mold is replaced, etc. Therefore, in this embodiment, only the process parameters of the production equipment combination that produce qualified injection molding products are recorded in the device pool, or the yield of a batch of injection molding products reaches the preset yield, and the equipment combination and the corresponding process parameters can be recorded in the device pool.

[0053] ​However, using single qualified injection molding product or single batch yield as the input standard, on the one hand, the construction of the device pool and the standard process parameter pool will make the number too large, and there may be a lot of repeated data, thereby increasing the workload of subsequent screening steps; on the other hand, the single qualified or single batch yield reaching the requirement cannot prove that the production equipment combination and its process parameters are reliable and stable. For example, if some production equipment combination is only used as an emergency for a batch or a period of time, or for other reasons, it only processes a very small batch of injection molding products, even if the injection molding products obtained meet the basic requirements, it does not mean that the production equipment combination and its process parameters are very reliable or can be stable and effective for a long time.

[0054] Therefore, in order to improve the reliability of each production equipment combination and its corresponding process parameters in the device pool, when constructing the device pool, for the same injection molding product, only the production equipment combinations that have processed more than a preset number of batches of the same injection molding product and have an average yield of a preset yield threshold are selected. Each production batch corresponds to a yield, so the average yield refers to the average value of the yield of all historical production batches of the production equipment combination (of course, the average value of the yield of historical production batches within a specified time period can also be specified).

[0055] S102, according to the type of injection molding product and the key parameters of the injection molding machine to be adjusted, select several groups of production equipment combinations consistent with the key parameters from the device pool as candidates, and recommend one of them as the best production equipment combination.

[0056] When purchasing new equipment or replacing products, the device needs to be parameter adjusted. At this time, according to the type of injection molding product to be produced and the key parameters (preferably tonnage) of the injection molding machine to be adjusted, the production equipment combination for producing the above injection molding product is selected from the device pool. The reason for taking tonnage as the key parameter is that generally the auxiliary equipment is configured with reference to the tonnage of the injection molding machine. The larger the tonnage of the injection molding machine, the larger the power of other auxiliary equipment that needs to be configured.

[0057] Of course, since there is more than one production equipment combination for producing the same injection molding product, multiple production equipment combinations can be selected. Then a group is randomly selected from the multiple production equipment combinations selected as the best production equipment combination.

[0058] In some other embodiments, a set of optimal production equipment combinations is matched for the type of injection molded product according to the yield and output of the type of injection molded product in historical data within a preset production period (e.g., the most recent month) from a plurality of sets of production equipment combinations. Specifically, according to the production scheduling plan, the total number of production batches and the total output (i.e., the sum of the output of each production batch in the total number of production batches) that the production equipment combination to be debugged will undertake in the production scheduling plan, and the preset yield, and according to the total output and the total number of production batches, and the preset yield, a plurality of production equipment combinations are further screened from the plurality of sets of production equipment combinations (specifically, the production equipment combinations in which the total number of historical production batches and the total historical output (i.e., the sum of the output of each historical production batch in the total number of historical production batches) are greater than or equal to the total number of production batches and the total output of the production equipment combination to be debugged in the production scheduling plan, and the average product yield is greater than or equal to the preset yield in one production scheduling plan), and then one of the production equipment combinations is randomly selected as the optimal production equipment combination. Generally, the production scheduling is based on the historical data of the factory, so the total number of production batches and the total output of the production equipment combination to be debugged can generally find at least one set of production equipment for benchmarking among the plurality of sets of production equipment combinations.

[0059] In addition, since there are still differences between the production equipment combination to be debugged and the existing production equipment combination, after setting the process parameters, the actual product yield of the new production equipment combination after trial operation can also be obtained (for example, from the perspective of reducing the cost of trial operation and saving materials, a production batch or a preset number of times can be trial operated, and whether the injection molded product obtained by trial operation is a qualified product is determined, if it is not a qualified product, the optimal production equipment combination is re-matched; if it is a qualified product, the actual product yield is obtained), and whether the actual product yield reaches the preset yield is determined, if it does not reach the preset yield, the production equipment combination with the highest yield is re-selected as the optimal production equipment combination.

[0060] Of course, if the actual production scheduling plan is adjusted or other circumstances make it impossible to match the production equipment combination in which the total number of historical production batches and the total historical output are greater than or equal to the total number of production batches and the total output, and the average product yield is greater than or equal to the preset yield, then at this time, the screening standard needs to be adjusted, and only the plurality of production equipment combinations in which the average product yield is greater than or equal to the preset yield within a specified time period (if the time interval is too long, the reliability as a reference will also decrease, so the most recent week or the most recent month can be specified) is matched.

[0061] Generally, a group of production equipment can only produce one injection molding product in the same production period, and different production quantities mean different working intensities of the equipment and different running states of the equipment. When the same injection molding product is produced in the same production quantity, the combination of the equipment with the highest yield indicates that the various process parameters of the equipment combination are optimal, and the equipment combination is in the best working state (of course, excluding factors such as breakdowns or human factors). Therefore, when an injection molding product needs to be produced, if a combination of production equipment can be found that has the same or larger production batch quantity and total production quantity and an average yield greater than or equal to a preset yield, the yield of the product can be ensured as much as possible by copying the process parameters of the equipment combination.

[0062] In some embodiments, for each injection molding product, the ratio of the number of times each production equipment combination is adopted to the number of times each production equipment combination is recommended is calculated as its reference index. When a plurality of production equipment combinations are filtered from the alternative production equipment combinations, the historical production batch quantity and the historical total production quantity of each production equipment combination are greater than or equal to the total production batch quantity and the total production quantity, and the average product yield is greater than or equal to the preset yield, the production equipment combination with the largest reference index is selected as the optimal production equipment combination.

[0063] At the beginning of the system operation, most users will directly adopt the production equipment combination recommended by the system without any prior reference or expert participation. However, after the system has been running for a period of time and a certain amount of historical data has been accumulated, users will usually decide whether to adopt the recommendation according to the actual situation, or, with the participation of experienced debugging staff, to filter a more suitable production equipment combination. Therefore, the ratio of the number of times each production equipment combination is adopted (including being recommended by the system and being adopted by the user, or not being recommended by the system but being actively selected by the user) to the number of times each production equipment combination is recommended can be used to measure whether the production equipment combination is suitable as a reference standard for debugging new production equipment combinations in the future. Specifically, the smaller the reference index, the more likely it is that the production equipment combination will not meet the user's expectations even if it is recommended, or that a more suitable production equipment combination will be filtered by experts, and therefore, in subsequent system recommendations, the production equipment combination will be gradually placed in a less favorable position. Of course, the larger the reference index, the more likely it is that the production equipment combination and its process parameters will be used as a reference standard for other production equipment, that is, the reliability of the process parameters is high, and a large amount of practice has proven this, and therefore, the production equipment combination with the larger reference index is preferably recommended.

[0064] S103、from the standard process parameter pool, match the process parameters of the production equipment combination for producing the type of injection molding product, and update the process parameters to the injection molding machine and auxiliary equipment to be debugged.

[0065] The process parameters of the production equipment combination as the best production equipment combination in producing the injection molding product have been added to the standard process parameter pool. Therefore, only the type of the injection molding product and the production equipment combination need to be input, and the corresponding process parameters can be matched from the standard process parameter pool, so as to match the process parameters to the injection molding machine to be adjusted and its auxiliary equipment.

[0066] In addition, in order to realize digital traceability, the injection molding product produced after the parameter adjustment by the above method in the embodiment can be provided with an identification, which contains the quality inspection result, the production equipment combination for producing the injection molding product, and the corresponding process parameters.

[0067] More specifically, the identification is a two-dimensional code, which can only be scanned by a specific APP to obtain the contained information, and the specific APP is only used by specific staff of the factory to avoid leakage of production process.

[0068] Embodiment 2: The application also provides another intelligent parameter adjustment method, which is described below with reference to Figure 2 which includes the following steps:

[0071] Of course, the user may agree or refuse the recommended best production equipment combination.

[0072] S203, in the case that the user approves the best production equipment combination, matching the process parameters of the injection molding product produced by the best production equipment combination from the standard process parameter pool, and updating the process parameters to the injection molding machine to be adjusted and the auxiliary equipment.

[0073] S204, in the case that the user does not accept the auxiliary equipment in the best production equipment combination, recommending other auxiliary equipment from the candidate production equipment combination until the user accepts or the candidate production equipment combination recommendation is exhausted, or the user configures the auxiliary equipment to form a new best production equipment combination.

[0074] The user can not accept the recommended auxiliary equipment in the optimal production equipment combination for some reason, at this time, the system can randomly select a group of production equipment combinations from the alternative production equipment combinations for recommendation. This process continues until the user accepts the recommendation or all alternative production equipment combinations are recommended. The production equipment combination accepted by the user becomes the optimal production equipment combination.

[0075] Of course, the user can also configure the auxiliary equipment by himself, and the auxiliary equipment configured by the user also becomes the optimal production equipment combination.

[0076] S205, matching the process parameters of the optimal production equipment combination for producing the type of injection molding product from the standard process parameter pool, and updating the process parameters to the injection molding machine to be adjusted and the auxiliary equipment.
