Description

Technical Field

[0001] The present invention relates to the technical field of injection molding machines, and in particular to a method, device, electronic equipment and storage medium for adjusting parameters of an injection molding machine. Background Art

[0002] In the production process of injection molded parts, the adjustment of the process parameters of the injection molding machine is a key step to ensure product quality. The traditional method of adjusting the parameters of the injection molding machine mainly relies on the experience and memory of the on-site technicians. The technicians need to manually judge the existing molding defects according to the molding conditions of the injection molded parts, and gradually adjust the various process parameters of the injection molding machine, such as pressure, speed, position, temperature, etc., based on experience until the product is qualified. However, this method has many shortcomings.

[0003] First, the injection molding workshop has a high frequency of transformation and production change, and there are many molding parameters, including mold opening and closing ejector parameters, sol parameters, injection parameters, barrel temperature parameters, and auxiliary machine parameters such as mold temperature controller. These parameters need to be input into the injection molding machine controller by the technician, which is not only labor-intensive but also prone to errors.

[0004] Secondly, the technical level of on-site technicians varies, and the debugging effects are also different. For inexperienced technicians, it may be difficult to accurately judge the type and degree of molding defects, and it is impossible to quickly find an effective adjustment plan, resulting in long machine adjustment time and low production efficiency.

[0005] Furthermore, the traditional parameter adjustment method of injection molding machines is highly dependent on the machine adjustment technicians. Once a complex product or molding defect is encountered, it may take multiple attempts and adjustments to find the best parameter combination, which not only increases production costs, but also affects the product delivery cycle.

[0006] Therefore, the industry urgently needs a method that can automatically, quickly and accurately adjust the parameters of injection molding machines to improve production efficiency, reduce production costs, and reduce dependence on on-site technicians. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The terms "first", "second", etc. in the present invention are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present invention can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0031] The process parameters in the operation process of the injection molding machine is actually a broad concept, which mainly refers to the sum of all process parameters related to the injection molding materials, injection molds, the injection molding machine itself and the injection molding auxiliary machines. The following parameters are mainly involved in the adjustment of the injection molding machine parameters: injection parameters, pressure holding process parameters, material storage part process parameters, temperature parameters, position parameters, pressure parameters, current ratio, injection molding machine lubrication system parameters, etc. The present invention does not make specific limitations on this.

[0032] In addition, in the description of the injection molding machine parameter adjustment method in the subsequent embodiments, the execution subject of the method can be understood as a machine adjustment system with a processor, which can realize the purpose of automatically recommending molding process parameters through feedback of the actual situation on site and executing data collection, data interaction, data processing, data analysis and other processes.

[0033] Combine the following Figure 1-Figure 5The invention describes an injection molding machine parameter adjustment method, device, electronic equipment and storage medium provided by the invention.

[0034] Figure 1 It is one of the flow charts of the method for adjusting parameters of an injection molding machine provided by the present invention, such as Figure 1 As shown, including but not limited to the following steps: Step 101, determining a target molding defect existing in an injection molded part produced by an injection molding machine in a current mold.

[0035] In the specific process of adjusting the injection molding machine, a set of initial process parameters can be determined through prior knowledge, and the initial process parameters can be used to control the injection molding machine to conduct trial production to obtain the injection molded parts of the current mold.

[0036] On-site monitoring or manual inspection can be used to determine whether the injection molded parts have some specific molding defects, such as missing materials, flash, bubbles, shrinkage marks, etc. Among them, on-site monitoring can collect images of injection molded parts produced by the current mold from different angles, and then use the trained deep network model to identify defects in the collected images.

[0037] It should be noted that there are many types of molding defects that may exist in injection molded parts, about more than 10 types. If it is identified that an injection molded part has multiple molding defects at the same time, a molding defect that needs to be improved first can be determined as a target molding defect through a pre-established judgment logic.

[0038] For example, the location of molding defects of injection molded parts can be divided into internal molding defects and external molding defects. The pre-established judgment logic can be to solve the internal molding defects by adjusting the machine first and then solve the external molding defects. The internal parts are usually hidden inside the product and are not easily seen by consumers directly, but once a failure occurs, the repair cost is high and may affect the overall performance of the product. After the internal parts problem is solved, it will turn to the debugging of complex products such as appearance parts. Although the problem of appearance parts does not affect the performance, it directly affects the consumer's willingness to buy.

[0039] Based on this judgment logic, if multiple molding defects exist at the same time, the internal molding defect is preferentially set as the target molding defect.

[0040] Step 102: determining a set of process parameters to be adjusted according to first defect information of the target molding defect.

[0041] The first defect information includes defect type, defect location and defect degree.

[0042] For each type of molding defect, the defect type of the molding defect can generally be defined, for example, it can be defined as material shortage, flash, etc. In the injection molding machine parameter adjustment method provided by the present invention, a molding defect library can be prepared in advance, in which different molding defects are classified and the characteristics of different types of molding defects are described, so that the user can quickly judge the defect type corresponding to the target molding defect.

[0043] The accuracy of the defect location of the molding defect is a key point for effective optimization. For example, after obtaining the target molding defect, the defect location can be defined as one of the regional locations such as the gate, main body, rib position, and end according to the molding structure characteristics of the injection molding machine.

[0044] For the degree of defects, the size, shape, location, quantity and distribution of the target molding defect can be comprehensively considered to define the degree of defects, such as mild, moderate, severe, etc. Specifically, the target molding defect can be compared with samples of different defect degrees in a pre-built defect database to match the defect degree corresponding to the target molding defect.

[0045] The set of process parameters to be adjusted includes process parameters to be adjusted that are related to solving the target molding defects, and all the process parameters to be adjusted are arranged in order of adjustment priority.

[0046] For example, if the target molding defect is a sink mark defect, the first defect information is collected first, including the defect type (sink mark), defect location (main body of the injection molded part), and defect degree (moderate). Based on this first defect information, the set of process parameters to be adjusted is determined to include injection pressure, injection time, holding pressure, and holding time. These parameters are closely related to the solution of the sink mark defect. Among them, based on historical experience, these process parameters to be adjusted are arranged in the order of adjustment priority, which are injection pressure, injection time, holding pressure, and holding time.

[0047] Step 103 : adjusting the process parameters to be adjusted in the process parameter set to be adjusted mold by mold according to the adjustment priority until it is determined that the injection molded part produced by the injection molding machine does not have the target molding defect.

[0048] Taking the above-mentioned optimization of the target molding defect of sink mark as an example, according to the adjustment priority order, the injection pressure is adjusted first. While keeping other parameters unchanged, the injection pressure is gradually increased, and the sink mark of the next injection molded part is observed. If the sink mark is improved but still exists, continue to adjust the injection pressure until the allowable value of the injection pressure is reached.

[0049] If the shrinkage defect still exists at this time, keep other parameters unchanged and continue to adjust the injection time and observe the shrinkage of the next molded part. If the shrinkage defect is further improved but still not completely eliminated, the injection time can be adjusted until the allowable value of the injection time is reached.

[0050] If the sink mark defect still exists at this time, continue to adjust the holding pressure and holding time in order of priority.

[0051] If after the above-mentioned multiple mold adjustments, it is finally found that when the injection pressure is increased to a certain value and the injection time is appropriately extended, the shrinkage mark defect on the injection molded part completely disappears, then it is determined that the injection molding machine parameter adjustment is completed, and the new molding defect can be determined as the target molding defect, and the subsequent machine adjustment steps can be continued.

[0052] As an optional embodiment, the above-mentioned judgment on molding defects (such as shrinkage defects, etc.) can be achieved by using visual recognition technology, that is, by collecting real-time images of the injection molded parts produced at various angles after each machine adjustment, and using an image recognition algorithm or a pre-trained image recognition model to perform defect detection on each real-time image, so as to judge whether the target molding defects still exist on the newly produced injection molded parts based on the detection results.

[0053] The injection molding machine parameter adjustment method provided by the present invention, during the process of adjusting the parameters of the injection molding machine, will analyze the molding defects of the injection molded parts in the previous mold to obtain detailed defect information, including the defect type, defect location and defect degree, and then determine the process parameters to be adjusted for the next mold according to the defect information, which can realize automatic optimization molding of the process parameters, effectively improve the efficiency of parameter adjustment, and reduce the debugging cost and time in the production process.

[0054] Figure 2 This is the second flow chart of the method for adjusting the parameters of the injection molding machine provided by the present invention. Figure 2 The following is a detailed introduction on how to adjust the process parameters to be adjusted in the process parameter set to be adjusted one by one according to the adjustment priority.

[0055] First, based on the defect type, defect location and defect degree of the target molding defect contained in the determined first defect information, a set of process parameters to be adjusted for optimizing the target molding defect can be determined, and all process parameters to be adjusted for optimizing the target molding defect are recorded in the set of process parameters to be adjusted in order of adjustment priority.

[0056] Furthermore, the first process parameter to be adjusted in the set of process parameters to be adjusted will be adjusted. If the target molding defect still exists after adjusting the first N-1 process parameters to be adjusted, the Nth process parameter to be adjusted for the current mold will continue to be selected.

[0057] Then, according to the Nth process parameter to be adjusted, the adjustment strategy related thereto is retrieved from the process parameter optimization database.

[0058] It should be noted that the process parameter optimization database is a database that pre-stores adjustment strategies for process parameters related to various molding defects, and the database can be obtained through computer-aided simulation experiments. These computer-aided (CAE) simulation experiments (Design of Experiments, DoE) simulate various molding defects that may occur during the injection molding process and test the effects of different process parameter combinations on molding defects. Through these experiments, the best adjustment strategy for each process parameter related to the molding defect can be determined and stored in the database for subsequent use.

[0059] After obtaining the adjustment strategy for the Nth process parameter to be adjusted, this adjustment strategy will be applied to adjust the value of the Nth process parameter to be adjusted, and a new, optimized value will be obtained to replace the original value of the Nth process parameter to be adjusted. The injection molding test of the next mold will be carried out again, and then the defect type, defect location and defect degree related to the injection molded parts obtained in the next mold will be detected to determine whether the target molding defect has been optimized or improved.

[0060] The following is an explanation in conjunction with specific embodiments: Assume that the defect type of the target molding defect is material shortage, the defect location is the main body of the injection molded part, and the defect degree is severe. You can first determine the process parameter set related to the target molding defect (material shortage) based on experience or simulation experiment results, including injection pressure, injection time, melt temperature, and mold temperature. Then, based on the adjustment priority of these process parameters to be adjusted, select the first process parameter that needs to be adjusted for the current mold, injection pressure.

[0061] The recommended adjustment strategy for adjusting the injection pressure to optimize the target molding defect of material shortage is retrieved from the process parameter optimization database. Assuming that the obtained adjustment strategy is: increase the injection pressure by 10%, the injection pressure setting of the injection molding machine is increased by 10% and the next mold production is run.

[0062] Collect the injection molded parts produced in the next mold. If it is found that the material shortage defect has improved but has not been completely eliminated, the injection pressure can be further adjusted until the allowable value of the injection pressure is reached or the preset number of continuous mold trials is reached.

[0063] For example, if the allowable value of injection pressure is aKP or the number of continuous mold trials for injection pressure is 2, when any of the termination conditions is met and the target molding defect has not been optimized, the adjustment of injection pressure will be stopped and the next process parameter to be adjusted, injection time, will be adjusted.

[0064] If the target molding defect has been eliminated or improved to an acceptable level, the process parameter values ​​for the current mold are stored and sent to the injection molding machine for subsequent normal production.

[0065] The injection molding machine parameter adjustment method provided by the present invention determines a set of process parameters to be adjusted with adjustment priority according to defect information of the injection molded part, and then obtains the adjustment strategy of the process parameters to be adjusted from the process parameter optimization database, so as to achieve accurate adjustment of the process parameters of the injection molding machine, thereby improving the molding quality of the injection molded part. Among them, by adjusting the process parameters mold by mold, the best process parameter combination can be quickly found, thereby shortening the debugging time and improving the production efficiency.

[0066] refer to Figure 2 As shown, as an embodiment, the injection molding machine parameter adjustment method provided by the present invention, after adjusting the Nth process parameter to be adjusted based on the adjustment strategy, further includes: Obtaining an injection molded part produced in the next mold run based on the adjusted Nth process parameter to be adjusted; If it is determined that the injection molded part has defects, whether the conditions for terminating the machine adjustment are met; When it is determined that the machine adjustment termination condition is met, if a continuing adjustment instruction is received, starting from the first process parameter to be adjusted in the process parameter set to be adjusted, the process parameters to be adjusted in the process parameter set to be adjusted are re-adjusted mold by mold until it is determined that the injection molded parts produced by the injection molding machine do not have the target molding defects; The condition for terminating the machine adjustment is that the total number of times the Nth process parameter to be adjusted related to the target molding defect has reached a first threshold or the adjusted value of the Nth process parameter to be adjusted has reached a preset allowable value.

[0067] Specifically, during the adjustment process of the injection molding machine, the target molding defects and the corresponding process parameter set to be adjusted are first determined according to the implementation methods mentioned in the above embodiments.

[0068] The present invention provides an injection molding machine parameter adjustment method, which aims to optimize the molding quality of injection molded parts by adjusting process parameters mold by mold. When a target molding defect is detected in an injection molded part, the process parameters to be adjusted in a process parameter set to be adjusted are adjusted one by one according to a preset adjustment priority.

[0069] If defects still exist in the injection molded parts produced in the next mold after the adjustment of a certain process parameter to be adjusted is completely executed, the next process parameter to be adjusted in the set of process parameters to be adjusted will be adjusted according to the priority.

[0070] In order to avoid an infinite cycle of adjustment process, the present invention sets a termination condition for machine adjustment. For example, when the number of adjustments to a process parameter to be adjusted reaches a preset number of continuous mold trials (first threshold), if the target molding defect has not been eliminated, the automatic machine adjustment is suspended. The termination condition for machine adjustment can also be added with the condition that the total number of machine adjustments reaches the preset number of mold trials.

[0071] Optionally, the continue debugging instruction is fed back by the user after receiving an inquiry on whether to continue debugging the machine.

[0072] Specifically, when the conditions for terminating machine adjustment are met, the machine adjustment system will ask the user whether to stop debugging. If the user chooses to continue debugging, a new round of adjustment process will start from the beginning, that is, starting from the first process parameter to be adjusted in the set of process parameters to be adjusted, and re-traversing each process parameter to be adjusted in the set of process parameters to be adjusted until the injection molded part meets the quality requirements or the user agrees to terminate automatic debugging.

[0073] As another optional embodiment, the continue debugging instruction is preset by the debugging system.

[0074] Specifically, when the conditions for terminating machine adjustment are met for the first time (or a preset number of times), a new round of adjustment process will automatically start from the beginning, that is, starting from the first process parameter to be adjusted in the set of process parameters to be adjusted, and re-traversing each process parameter to be adjusted in the set of process parameters to be adjusted until the injection molded part meets the quality requirements or the user agrees to terminate the automatic debugging.

[0075] If the above-mentioned termination condition is determined to be met again (or after exceeding the above-mentioned preset number of times), it is determined that the currently determined set of process parameters to be adjusted is not feasible for optimizing the target molding defect, and the current machine adjustment process will be automatically terminated.

[0076] Continue to refer to Figure 2 As shown, as an optional embodiment, the method for adjusting parameters of an injection molding machine provided by the present invention can perform the following operations when it is determined that the conditions for terminating the machine adjustment are not met: Re-acquiring the second defect information of the injection molded part, and retrieving the third defect information of the injection molded part in the previous mold; If it is determined based on the comparison between the second defect information and the third defect information that the defect types and defect positions included in the two are inconsistent, a new set of process parameters to be adjusted is re-determined based on the second defect information.

[0077] Specifically, after adjusting a process parameter to be adjusted, the present invention will perform molding defect detection on the injection molded parts produced in the next mold. If the detection result shows that there are molding defects, it is determined whether the termination adjustment conditions mentioned in the above embodiment are met.

[0078] If the conditions for terminating the machine adjustment are not met, continue to perform the subsequent automatic parameter adjustment steps: First, the injection molded parts will be inspected for molding defects in detail, and the defect type, defect location, and corresponding defect degree will be recorded as the second defect information. At the same time, the defect information of the previous injection molded parts, including the defect type, defect location, and defect degree, will be retrieved from the previous records or database as the third defect information.

[0079] Then, the defect type and defect location of the second defect information of the current mold will be compared with the third defect information of the previous mold. If the defect types and defect locations included in the two are inconsistent, it means that the current adjustment strategy may not be effective for the target molding defect, or new influencing factors have appeared in the injection molding process. At this time, all the process parameters to be adjusted that may be related to the second defect information of the current mold will be re-analyzed, and the adjustment strategies related to these parameters will be retrieved from the process parameter optimization database. Finally, a new set of process parameters to be adjusted will be determined based on all the process parameters to be adjusted and the adjustment strategies obtained from the new analysis, in which the adjustment priority between each process parameter to be adjusted has been set.

[0080] Finally, the new set of process parameters to be adjusted is used to restart and continue adjusting the process parameters of the injection molding machine mold by mold.

[0081] An example is as follows: Assume that during the injection molding process, the first target molding defect detected is the shrinkage defect on the surface of the injection molded part. Based on the shrinkage defect, the set of process parameters to be adjusted, which consists of injection pressure, injection time, melt temperature, etc., is determined. However, after adjusting the injection pressure, although the shrinkage phenomenon is alleviated, a new flash defect appears on the surface of the injection molded part. At this time, based on the comparison results of the second defect information (flash) and the third defect information (shrinkage), it can be determined that the two are inconsistent. Therefore, it is necessary to re-analyze which process parameters are related to the flash defect, and determine a new set of process parameters to be adjusted (such as adding mold gap, injection speed and other process parameters to be adjusted, and re-determine the adjustment priority between all these process parameters to be adjusted) to further improve the molding quality of the injection molded parts.

[0082] The injection molding machine parameter adjustment method provided by the present invention can dynamically adjust the process parameter set to be adjusted and its related adjustment strategy according to the defect changes in the actual machine adjustment process, so as to more efficiently solve the different molding defect problems of injection molded parts.

[0083] Continue to refer to Figure 2 As shown, as an optional embodiment, the method for adjusting parameters of an injection molding machine provided by the present invention, if the degree of defects is consistent, determines whether the Nth process parameter to be adjusted has been adjusted; If it is determined that the process parameter has been adjusted but the number of times of adjustment is less than the second threshold, and the adjusted Nth process parameter to be adjusted is within the preset condition range, a new set of process parameters to be adjusted is re-determined according to the second defect information; Otherwise, let N=N+1, and return to the step of determining the adjustment strategy for adjusting the Nth process parameter to be adjusted from the process parameter optimization database according to the first defect information, until the traversal of all the process parameters to be adjusted in the set of process parameters to be adjusted is completed.

[0084] The second threshold is used to determine whether a process parameter to be adjusted has been fully adjusted to an upper limit of the number of times, and the preset condition range means that the process parameter to be adjusted should be kept within a reasonable, adjustable or safe range after adjustment.

[0085] On the basis of the above embodiment, after the molding defect detection is performed on the injection molded part of the current mold, if it is found that the defect degree of the target molding defect is consistent with the defect degree of the previous mold or a certain reference defect, the following steps are performed: Check the records to see whether the process parameter to be adjusted (recorded as the Nth one) has been adjusted before. If it has not been adjusted before, continue to execute the subsequent steps to make the first adjustment.

[0086] If the Nth process parameter to be adjusted has been adjusted, it is checked whether the number of times it has been adjusted is less than the second threshold, and it is also checked whether the Nth process parameter to be adjusted is still within the preset condition range after adjustment.

[0087] If the number of adjustments is less than the second threshold and the parameter is within the preset range, it indicates that the parameter may have room for further adjustment. Under the above conditions, all process parameters to be adjusted that may be related to it can be re-analyzed based on the second defect information of the target molding defect determined by the current mold.

[0088] At the same time, a new adjustment strategy is retrieved from the process parameter optimization database, and a new set of process parameters to be adjusted is determined. It should be noted that the new set of process parameters to be adjusted may include some process parameters of the original set of process parameters to be adjusted, or may adopt a completely new set of process parameters.

[0089] Furthermore, if the Nth process parameter to be adjusted has been adjusted and reaches or exceeds the second threshold, or is not within the preset condition range after adjustment, it means that the adjustment of this process parameter to be adjusted cannot optimize the target molding defect, then N=N+1 will be set, that is, go to the next process parameter to be adjusted.

[0090] Repeat the steps from "determining the adjustment strategy according to the first defect information" to "determining the number of adjustments and the parameter range" until all the process parameters to be adjusted in the current process parameter set to be adjusted are traversed.

[0091] As an optional embodiment, after the machine adjustment system has completed the traversal of the current process parameter set to be adjusted, if an effective adjustment strategy has not been found or the injection molded part defect has not been eliminated, a query can be sent to the user to ask whether to continue adjusting the machine.

[0092] As another optional embodiment, after the machine adjustment system completes the traversal of the current set of process parameters to be adjusted, if no effective adjustment strategy is found or the injection molded part defects are not eliminated, the current machine adjustment process will be automatically stopped, and the machine adjustment results and manual parameter adjustment suggestions will be displayed on the user interface.

[0093] After the machine adjustment system asks the user whether to continue adjusting the machine, the user can choose to continue adjusting the machine according to the actual situation (possibly adopting a new adjustment strategy or adjustment method), or choose to terminate the adjustment (possibly manually setting certain process parameters or improving the entire injection molding process).

[0094] An example is as follows: Assume that during the injection molding process, the target molding defect of surface depression occurs in the injection molded part. Based on the first defect information, the set of process parameters to be adjusted related to the injection pressure and injection time is determined, and preliminary adjustments are made. However, after the adjustment, it is found that the degree of the defect has not improved, and the injection pressure has been adjusted many times (but still less than the second threshold), and it is still within the preset conditions after the adjustment. At this time, based on the second defect information (i.e., the defect information of the current mold), the process parameters related to the depression defect are re-analyzed, and a new set of process parameters to be adjusted (such as melt temperature, mold temperature, etc.) is determined. After traversing the new parameter set, if no effective adjustment strategy is found, a query is sent to the user, and the user decides whether to continue adjusting the machine.

[0095] The injection molding machine parameter adjustment method provided by the present invention can dynamically adjust the process parameter set to be adjusted and the adjustment strategy according to the defect degree in the actual production process and the historical adjustment process of each process parameter, so as to more efficiently solve the molding defect problem of injection molded parts and provide users with decision support on whether to continue adjusting the machine.

[0096] Continue to refer Figure 2As shown, as an optional embodiment, if a stop debugging instruction is received, the parameter adjustment for the target molding defect is terminated, and a manual parameter adjustment suggestion is output; The stop debugging instruction is fed back by the user after receiving the inquiry of whether to continue debugging.

[0097] Specifically, when the machine adjustment system is adjusting parameters for the target molding defect, if a stop debugging command is received, the current automatic debugging process will be terminated immediately and the current debugging status (such as the value of the adjusted process parameters, debugging progress, etc.) will be saved for subsequent reference.

[0098] Furthermore, after terminating the automatic debugging, the machine adjustment system will generate and output suggestions for manual adjustment of parameters based on the collected data and debugging experience. These suggestions are intended to help users manually adjust the machine to find the best parameter combination for optimizing the molding effect more quickly.

[0099] The injection molding machine parameter adjustment method provided by the present invention provides how to terminate the parameter adjustment for the target molding defect after receiving the stop debugging instruction, and output manual parameter adjustment suggestions. This improvement helps to improve the flexibility of the injection molding machine adjustment process.

[0100] Continue to refer Figure 2 As shown, as an optional embodiment, the determination of the target molding defects existing in the injection molded parts produced by the injection molding machine in the current mold mentioned in the above embodiment may include but is not limited to: Obtain all molding defects of the injection molded parts produced by the injection molding machine in the current mold; According to the product performance requirements of the injection molded part, all the molding defects are prioritized and then the target molding defect is determined.

[0101] During the injection molding production process, due to the influence of various factors, the injection molded parts may have various molding defects, such as flash, material shortage, bubbles, deformation, etc. In order to improve product quality and production efficiency, it is necessary to promptly discover and solve these molding defects. This embodiment aims to elaborate on how to determine the target molding defects existing in the injection molded parts produced by the injection molding machine in the current mold.

[0102] Specifically, after the injection molding machine completes the current mold test, the machine adjustment system will first obtain all molding defect information of the injection molded parts in the mold. This can be achieved in a variety of ways, including but not limited to image recognition, sensor detection or manual inspection.

[0103] Among them, image recognition can use a camera to capture images of injection molded parts and detect molding defects through image recognition algorithms, which will not be elaborated here.

[0104] Sensor detection can be achieved by installing sensors on the injection molding machine to monitor the changes in parameters during the injection molding process, such as pressure, temperature, etc., in real time to determine whether there are molding defects. Alternatively, sensors can be used to detect relevant parameters of the generated injection molded parts, such as the thickness, hardness, and light transmittance of the target part.

[0105] Manual inspection is performed by dedicated quality inspectors who visually inspect the injection molded parts and record any molding defects found.

[0106] After obtaining all molding defects, these defects can be prioritized according to the product performance requirements of the injection molded parts. Usually, the following steps can be used: First, according to the use scenarios and customer needs of injection molded parts, its key performance requirements, such as dimensional accuracy, appearance quality, mechanical strength, etc., are clarified.

[0107] Then, analyze the impact of each molding defect on product performance, including whether it affects function, reduces service life, affects appearance, etc.

[0108] Next, all molding defects are sorted according to the degree of influence of each molding defect, the priority of each molding defect is determined, and the priority sorting is completed.

[0109] Finally, according to the priority sorting results, the molding defect with the highest priority can be selected as the target molding defect, and the defect information of the target molding defect (such as defect type, defect location, defect degree, etc.) can be recorded in the machine adjustment system for subsequent analysis and processing.

[0110] The injection molding machine parameter adjustment method provided by the present invention elaborates in detail how to determine the target molding defects existing in the injection molded parts produced by the injection molding machine in the current mold. This process includes obtaining all molding defects, prioritizing the defects according to product performance requirements, and determining the target molding defects. This method helps to improve the quality and efficiency of injection molding production, reduce the defective rate, and improve customer satisfaction.

[0111] Based on the content of the above embodiment, as an optional embodiment, the first defect information of the target molding defect is obtained in the following manner: Acquire a sample image and / or a defect description vector of the injection molded part produced in the current mold; Inputting the sampled image and / or the defect description vector into an object recognition model to obtain the first defect information output by the object recognition model; The target recognition model is obtained after training based on image samples with defect information labels and vector samples with defect information labels.

[0112] During the adjustment process of the injection molding machine, detecting and identifying the molding defects of the injection molded parts in each adjustment mold is a key step to improve product quality and production efficiency. The present invention provides a specific implementation method.

[0113] First, collect the analysis basis for analyzing the molding defects of the injection molded parts produced by the current mold. Generally speaking, all quantifiable analysis basis can be constructed into a defect description vector. For the analysis basis that cannot be quantified, relevant sampling images can be obtained. Specifically: For the injection molded parts produced by the current mold (i.e., the current injection molding process), one or more sampling images at different angles are acquired through a camera or other image acquisition device. These sampling images should clearly show the surface features of the injection molded parts and possible molding defects.

[0114] In addition to acquiring sampling images, other sensors can be used to obtain defect description vectors about injection molded parts, such as quantifiable analysis data related to the size, shape, color, texture, transmittance, thickness, etc. of the injection molded parts, and the defect feature information obtained through specific algorithm processing.

[0115] Furthermore, the sampled image and / or defect description vector is input into a trained target recognition model, which can receive, process and analyze the image and / or vector data, and output first defect information about the target molding defect of the injection molded part, such as defect type, defect location, defect size, defect degree, etc.

[0116] Before training the target recognition model, the initial model needs to be trained using image samples with defect information labels and vector samples with defect information labels. These samples generally cover various types of defects that may occur in injection molded parts, and each sample should be accompanied by accurate defect information labels.

[0117] In the process of training the target recognition model using the prepared samples, the target recognition model will learn how to extract features from the input image and / or vector data, and determine whether the injection molded part has defects and the corresponding defect information based on these features.

[0118] The injection molding machine parameter adjustment method provided by the present invention proposes a method for obtaining the first defect information of the target molding defect of the injection molded part by using a target recognition model, which has the advantages of high efficiency, accuracy and reliability, and is of great significance for improving the production quality and production efficiency of injection molded parts.

[0119] The injection molding machine parameter adjustment method provided by the present invention can realize one-key saving and one-key issuing of determined molding process parameters. Figure 3 FIG. 3 is a flow chart of the method for adjusting parameters of an injection molding machine provided by the present invention. Figure 3 As shown, after adjusting the process parameters to be adjusted in the process parameter set to be adjusted mold by mold according to the adjustment priority until it is determined that the injection molded part produced by the injection molding machine does not have the target molding defect, the method may further include: Saving all process parameters, wherein the process parameters include one or more of injection molding material parameters, injection mold parameters, injection molding machine parameters, and injection molding auxiliary machine parameters; Receiving a parameter sending instruction from a user, wherein the sending instruction at least includes an address of a control system of a target injection molding machine; The process parameters are sent to the control system of the target injection molding machine according to the address.

[0120] Specifically, the machine adjustment system will obtain the initial process parameters for adjusting the injection molding machine from the background process card, such as the type of injection material, melting temperature, mold temperature and structure, injection pressure and speed of the injection molding machine, and process parameters of auxiliary machines.

[0121] The process parameters used by the current module can be displayed on the parameter recommendation main page, including displaying these initial process parameters on the parameter recommendation main page before starting to adjust the machine.

[0122] Furthermore, the injection molding machine parameter adjustment method provided in any of the above embodiments is run to adjust each of the process parameters to be adjusted in the process parameter set to be adjusted mold by mold according to the adjustment priority. After each adjustment, the injection molded parts produced by the injection molding machine are monitored to determine whether there are target molding defects, that is, during the adjustment process, the real-time parameters of the injection molding machine are used to monitor the production status, such as injection pressure, temperature, speed, etc., to ensure the accuracy and effectiveness of the adjustment.

[0123] It should be noted that in the actual machine adjustment process, the user can manually set the defect type of the target molding defect, and after setting the defect type, can further set other defect information such as defect location and defect degree. When the user operates on the system interface, after each defect information is set, it will automatically jump to the next setting area. The subsequent machine adjustment system will automatically perform machine adjustment tests based on the defect information set by the user, and output a set of optimized process parameters to the parameter recommendation main page on the system interface.

[0124] After determining that the injection molded part does not have the target molding defects, the machine adjustment system will save all the process parameters involved (including the process parameters that have been modified and not modified during the adjustment process).

[0125] In this way, it is possible to respond to the parameter sending instructions sent by the user through the system interface or other means, and according to the address (or identification number, etc.) of the control system of the target injection molding machine contained in the parameter sending instructions, send all the saved process parameters to the control system of the target injection molding machine, thereby ensuring that other injection molding machines can use these optimized parameters for production, thereby improving production efficiency and product quality.

[0126] The injection molding machine parameter adjustment method provided by the present invention can, on the one hand, display various real-time data in the machine adjustment process to the user in real time through the system interface, and can respond to the user's control of the machine adjustment process in real time through interaction with the user. In addition, by saving the process parameters during or at the end of the machine adjustment with one key, the injection molding machine process parameters can be sent with one key, which not only improves the efficiency and stability of injection molding production, but also reduces the workload and production costs of technicians.
