Since the first hot pressing control parameter includes the hot pressing control parameters of the same hot pressing forming stage, and the second hot pressing control parameter includes the hot pressing control parameters corresponding to different hot pressing forming stages, the influence of the hot pressing control parameters of different hot pressing forming stages on the film quality can be analyzed, and the hot pressing control parameters of different hot pressing forming stages can be dynamically adjusted to improve the film quality of the hot pressing equipment.

Description

Technical Field

[0001] The present invention relates to the technical field of equipment control, and in particular to a hot pressing equipment control method and system. Background Art

[0002] After surface treatment, carbon fiber needs to be glued, which is used to protect the surface activity generated by the surface treatment of carbon fiber and enhance the bonding strength between carbon fiber and matrix resin. The glue forms a smooth and tough film on the surface of filaments and fibers, which improves wear resistance and prevents the generation of hair. At the same time, it can maintain the original elasticity. The glue penetrates into the fiber and glues part of the fiber to increase the bonding force. At present, there are two main processes for the production of thermosetting resin matrix carbon fiber prepregs at home and abroad: solution impregnation and hot melt. The advantage of the solution impregnation method is that the reinforcing material is easily impregnated by the resin matrix; thin prepregs can be manufactured, as well as thick prepregs. The traditional hot pressing equipment control method mainly relies on parameters set by experience, and lacks precise control of the relationship between film quality and hot pressing parameters, resulting in unstable film quality and low efficiency.

[0022] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0023] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0024] The technical solution provided by the embodiment of the present invention can be applied to control scenarios of various hot pressing equipment. For example, the hot pressing equipment can be a hot pressing molding machine, such as a rolling hot pressing molding machine, or other types of hot pressing molding machines.

[0025] Thermoforming is a commonly used processing method in the plastic processing industry. Its core is to use a heated mold to inject plastic samples, then apply pressure at high temperature to melt and solidify the material, and finally cool and take out the molded product.

[0026] The process of thermoforming usually includes the following stages:

[0027] Material heating, first the material (such as plastic) is heated to its thermoplastic temperature, which is usually carried out in a heating furnace.

[0028] Mold preheating: The mold is preheated to the appropriate temperature to prepare for material injection and molding.

[0029] Compression molding: The heated material is placed in a preheated mold, and the necessary pressure and temperature are applied to form the material in the mold.

[0030] Cooling and solidification: the molded parts are placed in a cooling chamber to cool, and then taken out for use after solidification.

[0031] In addition, there are other hot press molding technologies, such as carbon fiber hot press molding, whose process involves placing prepreg into a mold, heating the mold through a heating system, and then applying pressure to shape the material.

[0032] Traditional hot pressing equipment control methods mainly rely on parameters set by experience and lack precise control over the relationship between film quality and hot pressing parameters, resulting in unstable film quality and low efficiency.

[0033] Based on this, an embodiment of the present invention provides a technical solution, in which a mathematical model between hot pressing control parameters and film forming quality is established, and based on the mathematical model, the hot pressing control parameters are dynamically adjusted to improve the film forming quality of the hot pressing equipment, thereby optimizing production efficiency.

[0034] Please refer to Figure 1 , is a schematic diagram of an application scenario of a hot pressing device control according to an embodiment of the present invention, such as Figure 1 As shown, in this application scenario, a hot pressing device and a control device are included, wherein the hot pressing device and the control device can be communicatively connected.

[0035] Regarding the hot pressing equipment, it can be different types of hot pressing equipment, such as: rolling hot pressing equipment, carbon fiber hot pressing molding equipment, etc.

[0036] Regarding the control device, it may include a control end and a user end, wherein the control end may control the hot pressing parameters of the hot pressing device, the control end may be mounted on the hot pressing device, or may be independent of the hot pressing device, and it is connected to various components of the hot pressing device to transmit control parameters, such as: connected to a heating device, a pressurizing device, etc. The user end may realize the human-computer interaction function, and it has various rich human-computer interaction functions such as displaying a human-computer interaction interface and receiving human-computer interaction instructions.

[0037] Please refer to Figure 2 , is a flow chart of a method for controlling a hot pressing device according to an embodiment of the present invention. Figure 2 As shown, the hot pressing equipment control method includes:

[0038] Step 201: Acquire a pre-established first mathematical model and a second mathematical model.

[0039] Step 202, obtaining real-time hot pressing control parameters corresponding to the hot pressing equipment in multiple hot pressing forming stages.

[0040] Step 203 , adjusting the real-time hot pressing control parameters of the hot pressing equipment corresponding to the multiple hot pressing forming stages according to the first mathematical model and the second mathematical model, so as to control the film forming of the hot pressing equipment.

[0041] In step 201, the first mathematical model is used to characterize the relationship between the first hot pressing control parameter and the film quality, and the second mathematical model is used to characterize the relationship between the second hot pressing control parameter and the film quality. The first hot pressing control parameter includes the hot pressing control parameters of the same hot pressing molding stage, and the second hot pressing control parameter includes the hot pressing control parameters corresponding to different hot pressing molding stages.

[0042] The first hot pressing control parameters include the hot pressing control parameters in the same hot pressing molding stage, that is, the first mathematical model is used to characterize the relationship between the hot pressing control parameters in the same hot pressing molding stage and the film forming quality.

[0043] For example, if three hot press forming stages are included, hot press forming stage 1 corresponds to one first mathematical model, hot press forming stage 2 corresponds to one first mathematical model, and hot press forming stage 3 corresponds to one first mathematical model. Therefore, the number of first mathematical models is the same as the number of hot press forming stages.

[0044] The second hot pressing molding parameters include hot pressing control parameters corresponding to different hot pressing molding stages, that is, the second mathematical model is used to characterize the relationship between the hot pressing control parameters in multiple hot pressing molding stages and the film quality.

[0045] For example, if there are three hot pressing molding stages, the hot pressing molding stage 1, the hot pressing molding stage 2 and the hot pressing molding stage 3 may correspond to one second mathematical model. Therefore, there is only one second mathematical model, and it can characterize the relationship between all hot pressing control parameters and film quality.

[0046] In the embodiment of the present invention, no matter whether it is the hot pressing control parameters of the same hot pressing molding stage or the hot pressing control parameters of multiple hot pressing molding stages, the corresponding relationship between them and the film forming quality can adopt multiple implementation methods.

[0047] As an optional implementation, the corresponding relationship may be a functional relationship between the hot pressing control parameters and the film forming quality.

[0048] For example, the film quality is Q, and the hot pressing control parameters include A, B and C. Then, for the first mathematical model, it can include: Q1 = F1 (A), Q2 = F2 (B) and Q3 = F3 (C). For the second mathematical model, it can be expressed as: Q3 = F4 (A|B|C).

[0049] As an optional implementation, the corresponding relationship may be a value range relationship between the hot pressing control parameter and the film forming quality.

[0050] For example, the film quality is Q, and the hot pressing control parameters include A, B and C. Then, for the first mathematical model, it can include: when A∈(A1, A2), Q∈(Q1, Q2); when B∈(B1, B2), Q∈(Q3, Q4); when C∈(C1, C2), Q∈(Q5, Q6) For the second mathematical model, it can be expressed as: when A∈(A1, A2), and B∈(B1, B2), and C∈(C1, C2), Q∈(Q6, Q7). Among them, A1, A2, B1, B2, C1, C2 are different hot pressing control parameter values, and Q1~Q6 are different film quality values.

[0051] As an optional implementation, the first mathematical model and the second mathematical model may also be machine learning models, and accordingly, the corresponding relationship is represented by the model.

[0052] For example, assuming that the film quality is Q, and the hot pressing control parameters include A, B, and C, the first mathematical model can determine the corresponding film quality according to A, B, or C. The second mathematical model can determine the corresponding film quality according to A, B, and C.

[0053] Regardless of which of the above-mentioned implementation methods is adopted, the model construction process may include: obtaining historical data of the hot pressing equipment, the historical data including: a first historical hot pressing control parameter with a film quality higher than a preset film quality and a second historical hot pressing control parameter with a film quality lower than the preset film quality, the first historical hot pressing control parameter and the second historical hot pressing control parameter both including hot pressing control parameters corresponding to different hot pressing molding stages; constructing a first mathematical model based on the first historical hot pressing control parameter; constructing a second mathematical model based on the first historical hot pressing control parameter and the second historical hot pressing control parameter.

[0054] It can be understood that the historical data is the historical production data of the current hot pressing equipment or the historical production data of the hot pressing equipment of the same type as the current hot pressing equipment.

[0055] In some embodiments, the preset film quality may be a film quality that can meet high production efficiency. For example, assuming that the film quality is proportional to the production efficiency, the film quality is a value between 0 and 100, the production efficiency is a value between 0 and 100%, and the high production efficiency is a value between 70% and 100%, then the preset film quality may be a value between 80 and 100.

[0056] In an embodiment of the present invention, the film quality can be determined by a mature film quality assessment method in the art, for example: the film quality is determined based on parameters related to the film quality, such as the uniformity of the film, the stability of the film, and the area of ​​the film.

[0057] Further, based on the relationship between the film forming quality and the preset film forming quality, the historical data is divided into a first historical hot pressing control parameter and a second historical hot pressing control parameter.

[0058] Based on the first historical thermal pressure control parameter, a first mathematical model can be constructed. Based on the first historical thermal pressure control parameter and the second historical thermal pressure control parameter, a second mathematical model can be constructed.

[0059] In the embodiment of the present invention, the hot pressing forming stage can be divided into three stages: a material heating stage, a mold preheating stage and a hot pressing stage.

[0060] Correspondingly, the hot pressing control parameters in the material heating stage may include: material heating temperature and material heating time; the hot pressing control parameters in the mold preheating stage may include: mold preheating temperature and mold preheating time; the hot pressing control parameters in the hot pressing stage may include: pressure and temperature.

[0061] As an optional implementation, the process of constructing the first mathematical model includes: constructing a mathematical model corresponding to the material heating stage according to the material heating parameters of the material heating stage and the film forming quality corresponding to the material heating parameters of the material heating stage; constructing a mathematical model corresponding to the mold preheating stage according to the mold preheating parameters of the mold preheating stage and the film forming quality corresponding to the mold preheating parameters of the mold preheating stage; constructing a mathematical model corresponding to the hot pressing stage according to the hot pressing parameters of the hot pressing stage and the film forming quality corresponding to the hot pressing parameters of the hot pressing stage; determine the first mathematical model according to the mathematical model corresponding to the material heating stage, the mathematical model corresponding to the mold preheating stage and the mathematical model corresponding to the hot pressing stage.

[0062] In this embodiment, mathematical models corresponding to the three hot pressing forming stages are constructed respectively according to the historical data of the three hot pressing forming stages. Then, the mathematical model corresponding to the material heating stage, the mathematical model corresponding to the mold preheating stage and the mathematical model corresponding to the hot pressing stage are integrated into the first mathematical model.

[0063] Please refer to Figure 3 , is a schematic diagram of a first mathematical model according to an embodiment of the present invention, such as Figure 3 As shown, the first mathematical model includes: a mathematical model corresponding to the material heating stage, a mathematical model corresponding to the mold preheating stage and a mathematical model corresponding to the hot pressing stage. These three mathematical models can be regarded as internal sub-models of the first mathematical model.

[0064] In addition, in combination with the above-mentioned definition and explanation of the first mathematical model, the three mathematical models can be machine learning models, function and value range correspondence models, etc. In combination with different implementations, different implementations can be used to construct the three mathematical models.

[0065] For example, for a machine learning model, a mathematical model can be obtained by model training, wherein the training data for model training is the historical data of the corresponding hot pressing forming stage.

[0066] For example, for a function, a function curve can be constructed according to the historical data of the corresponding hot pressing forming stage, and a function expression can be obtained according to the function curve.

[0067] For example, for the model corresponding to the value range, different film quality ranges and the corresponding value ranges of the hot pressing control parameters can be analyzed by statistically analyzing the rules of historical data of the corresponding hot pressing molding stage.

[0068] Furthermore, the first mathematical model is a single mathematical model, which can characterize the influence of the hot pressing control parameters of a single hot pressing molding stage on the film quality, and realize the adjustment of the hot pressing control parameters of a single hot pressing molding stage.

[0069] Regarding the second mathematical model, its construction process may include: constructing an initial second mathematical model based on the first historical hot pressure control parameters and the film formation quality corresponding to the first historical hot pressure control parameters; constructing a negative impact mathematical model for the initial second mathematical model based on the second historical hot pressure control parameters and the film formation quality corresponding to the second historical hot pressure control parameters, the negative impact mathematical model is used to characterize the relationship between the hot pressure control parameters with negative impact and the film formation quality; determining the second mathematical model based on the negative impact mathematical model and the initial second mathematical model.

[0070] In this embodiment, the construction method of the initial second mathematical model can refer to the construction method of the first mathematical model, the difference is that the second mathematical model corresponds to more parameters, which are the parameters of all hot pressing forming stages.

[0071] The construction method of the negative impact mathematical model can also refer to the construction method of the first mathematical model, the difference is that the negative impact mathematical model corresponds to more parameters, which are the parameters of all hot pressing molding stages. In addition, the negative impact mathematical model analyzes the negative impact of the hot pressing control parameters with negative impact on the film quality, which can be simply understood as the reduction value of the film quality.

[0072] Furthermore, the negative impact mathematical model and the initial second mathematical model are integrated to determine the second mathematical model.

[0073] Please refer to Figure 4 , is a schematic diagram of a second mathematical model according to an embodiment of the present invention, such as Figure 4 As shown, the negative impact mathematical model has a negative impact on the output result of the initial second mathematical model, and the integrated output result of the two models is the final output result of the second mathematical model.

[0074] In step 202, real-time hot pressing control parameters corresponding to the hot pressing equipment in multiple hot pressing forming stages are obtained. For example, the real-time hot pressing control parameters can be understood as the hot pressing control parameters given at time t.

[0075] These heat pressure control parameters may be system-given parameters or manually-given parameters, or may also be preset parameters, so real-time heat pressure control parameters may be obtained.

[0076] As the hot pressing equipment is running and the actual operating environment changes, the film quality of the hot pressing equipment is difficult to guarantee. Therefore, it is necessary to dynamically adjust the real-time hot pressing control parameters to improve the film quality.

[0077] For example, the hot pressing molding stage includes: material heating stage, mold prediction stage and hot pressing stage, and the real-time hot pressing control parameters include: material heating temperature and material heating time in the material heating stage; mold preheating temperature and mold preheating time of the hot pressing control parameters in the mold preheating stage; pressure and temperature in the hot pressing stage.

[0078] In step 203, the real-time hot pressing control parameters corresponding to the hot pressing equipment in the plurality of hot pressing forming stages are adjusted according to the first mathematical model and the second mathematical model.

[0079] As an optional implementation, step 203 includes: determining a first film quality prediction value based on the first mathematical model and the real-time hot pressing control parameters corresponding to the material heating stage; adjusting the real-time hot pressing control parameters corresponding to the material heating stage based on the first film quality prediction value; determining a second film quality prediction value based on the first mathematical model and the real-time hot pressing control parameters corresponding to the mold preheating stage; adjusting the real-time hot pressing control parameters corresponding to the mold preheating stage based on the second film quality prediction value; determining a third film quality prediction value based on the first mathematical model and the real-time hot pressing control parameters corresponding to the hot pressing stage; adjusting the real-time hot pressing control parameters corresponding to the hot pressing stage based on the third film quality prediction value; determining a fourth film quality prediction value based on the second mathematical model, the adjusted real-time hot pressing control parameters corresponding to the material heating stage, the adjusted real-time hot pressing control parameters corresponding to the mold preheating stage, and the adjusted real-time hot pressing control parameters corresponding to the hot pressing stage; and adjusting the real-time hot pressing control parameters of the hot pressing equipment corresponding to multiple hot pressing molding stages respectively based on the fourth film quality prediction value.

[0080] In this embodiment, the predicted value of film quality under the influence of a single hot pressing molding stage is first predicted based on the first mathematical model and the real-time hot pressing control parameters of each hot pressing molding stage. The real-time hot pressing control parameters of each stage are first adjusted using the predicted value of film quality under the influence of the single hot pressing molding stage. Then, the predicted values ​​of film quality under the influence of multiple hot pressing molding stages are predicted based on the second mathematical model and the adjusted real-time hot pressing control parameters. The real-time hot pressing control parameters are adjusted again using the predicted values ​​of film quality under the influence of multiple hot pressing molding stages.

[0081] In this way, the two-step adjustment method is adopted, combined with different impact levels, which can improve the parameter adjustment efficiency and parameter adjustment accuracy.

[0082] In some embodiments, adjusting the real-time hot pressing control parameters corresponding to the material heating stage according to the first film quality prediction value may include: if the gap between the first film quality prediction value and the aforementioned preset quality is small, then the real-time hot pressing control parameters corresponding to the material heating stage may not be adjusted; otherwise, adjusting the real-time hot pressing control parameters corresponding to the material heating stage, and based on the adjusted real-time hot pressing control parameters, combining the first mathematical model again to predict the film quality until the gap between the film quality prediction value and the aforementioned preset quality is small, and then stopping adjusting the parameters. Among them, the small gap referred to in the single hot pressing molding stage can be defined as the quality difference value is in the range of 0 to 1 in the embodiment of the present invention.

[0083] In the embodiment of the present invention, the value of the control parameter adjusted each time can be determined in combination with the size of the gap. For example, if the gap is large, the adjusted parameter value can be correspondingly large. Also, for the increase or decrease of the parameter, the parameter value can be increased first. If it is found that the adjustment result is not a positive impact, the parameter value can be reduced next time.

[0084] Correspondingly, the adjustment method of the real-time hot pressing control parameters in the other two hot pressing forming stages can refer to the adjustment method of the real-time hot pressing control parameters corresponding to the material heating stage, which will not be described in detail here.

[0085] In some embodiments, according to the fourth film quality prediction value, adjusting the real-time hot pressing control parameters corresponding to the hot pressing equipment in multiple hot pressing molding stages respectively may include: if the gap between the fourth film quality prediction value and the aforementioned preset quality is small, then the real-time hot pressing control parameters may no longer be adjusted; otherwise, adjusting the real-time hot pressing control parameters corresponding to multiple hot pressing molding stages, and based on the adjusted real-time hot pressing control parameters, predicting the film quality again in combination with the second mathematical model until the gap between the film quality prediction value and the aforementioned preset quality is small, and then stopping adjusting the parameters. Among them, the small gap here can be defined as the quality difference value being in the range of 0 to 0.1 in the embodiment of the present invention.

[0086] In some embodiments, when adjusting the real-time hot pressing control parameters corresponding to the multiple hot pressing molding stages, the parameters that have not been adjusted are adjusted first, or the parameters that have a greater impact on the film quality are adjusted first. Alternatively, the parameters that have been adjusted less strongly are adjusted first.

[0087] In addition, adjusting the parameters can be a step performed before the control. After the adjustment is completed, the final parameters are used to control the film formation of the hot pressing device. The film formation control of the hot pressing device can refer to the mature technology in the field, which will not be described in detail here.

[0088] In the embodiment of the present invention, human-computer interaction can also be combined to realize the control of hot pressing equipment. As an optional implementation, the hot pressing equipment control method also includes: feeding back the real-time hot pressing control parameters corresponding to the hot pressing equipment in multiple hot pressing molding stages to the user end; receiving the predicted film quality fed back by the user end; correspondingly, adjusting the real-time hot pressing control parameters corresponding to the hot pressing equipment in multiple hot pressing molding stages according to the first mathematical model and the second mathematical model, including: adjusting the real-time hot pressing control parameters corresponding to the hot pressing equipment in multiple hot pressing molding stages according to the first mathematical model, the second mathematical model and the predicted film quality.

[0089] According to the first mathematical model, the second mathematical model and the predicted film quality, the real-time hot pressing control parameters corresponding to the hot pressing equipment in multiple hot pressing molding stages are adjusted, including: determining a first film quality prediction value according to the first mathematical model and the real-time hot pressing control parameters corresponding to the material heating stage; adjusting the real-time hot pressing control parameters corresponding to the material heating stage according to the first film quality prediction value; determining a second film quality prediction value according to the first mathematical model and the real-time hot pressing control parameters corresponding to the mold preheating stage; adjusting the real-time hot pressing control parameters corresponding to the mold preheating stage according to the second film quality prediction value; determining a third film quality prediction value according to the first mathematical model and the real-time hot pressing control parameters corresponding to the hot pressing stage; adjusting the real-time hot pressing control parameters corresponding to the hot pressing stage according to the third film quality prediction value; determining a fourth film quality prediction value according to the second mathematical model, the adjusted real-time hot pressing control parameters corresponding to the material heating stage, the adjusted real-time hot pressing control parameters corresponding to the mold preheating stage and the adjusted real-time hot pressing control parameters corresponding to the hot pressing stage; and adjusting the real-time hot pressing control parameters corresponding to the hot pressing equipment in multiple hot pressing molding stages according to the fourth film quality prediction value and the predicted film quality.

[0090] In this implementation, the implementation of the first few steps can refer to the aforementioned embodiments.

[0091] Regarding adjusting the real-time hot pressing control parameters corresponding to the hot pressing equipment in multiple hot pressing molding stages according to the fourth film quality prediction value and the predicted film quality, it can include: if the fourth film quality prediction value is greater than the preset film quality and greater than the predicted film quality, no adjustment is required. Otherwise, adjustment is required. Compared with the aforementioned implementation, the parameter adjustment standard here also adds the predicted film quality, so the adjustment requirements are higher.

[0092] The first mathematical model and the second mathematical model may also be updated.

[0093] Therefore, as an optional implementation, the hot pressing equipment control method also includes: obtaining the real-time film forming quality of the hot pressing equipment; obtaining the adjusted real-time hot pressing control parameters corresponding to the hot pressing equipment in multiple hot pressing molding stages; obtaining the external influencing parameters corresponding to the real-time film forming quality, and determining the external influencing weight value according to the external influencing parameters; determining whether to update the first mathematical model and the second mathematical model according to the real-time film forming quality, the adjusted real-time hot pressing control parameters corresponding to the hot pressing equipment in multiple hot pressing molding stages, and the external influencing weight value; if it is determined to update the first mathematical model and the second mathematical model, update the first mathematical model and the second mathematical model according to the adjusted real-time hot pressing control parameters and the real-time film forming quality corresponding to the hot pressing equipment in multiple hot pressing molding stages.

[0094] It can be understood that the real-time film-forming quality of the hot pressing equipment is the film-forming quality of the product produced after the hot pressing equipment is controlled based on the adjusted hot pressing control parameters.

[0095] In some embodiments, the external influencing parameters may be material performance parameters, external temperature parameters, equipment performance parameters, etc.

[0096] The external influence weight value can be determined by the influence relationship between the external influence parameter and the external influence weight value. For example, K = f(x1, x2, x3, ... xn), where f(x) represents the influence relationship, x1 ~ xn represent the external influence parameters, and K represents the external influence weight value. In different application scenarios, the influence relationship can be determined by experiments, statistical historical data, etc.

[0097] Furthermore, if the external influence weight value is large, or the difference between the adjusted real-time hot pressing control parameters corresponding to the hot pressing equipment in multiple hot pressing molding stages and the real-time hot pressing control parameters before adjustment is not large, and the real-time film quality is higher than the preset film quality, the model is not updated. Otherwise, in other cases, the model needs to be updated.

[0098] Furthermore, if updating is required, the adjusted real-time hot pressing control parameters and real-time film forming quality corresponding to the hot pressing equipment in multiple hot pressing molding stages are used as new historical data to update the first mathematical model and the second mathematical model.

[0099] For example, train the machine learning model again; increase the corresponding relationship between the value range; change the function parameters, etc.

[0100] Through this implementation, the control parameters can be continuously optimized to form a closed-loop control system.

[0101] In some embodiments, some information may be fed back to inexperienced operators to assist them in learning operations.

[0102] Therefore, the hot pressing equipment control method may also include: in the process of film forming control of the hot pressing equipment, obtaining video data corresponding to multiple hot pressing forming stages respectively collected by the camera; determining key video data corresponding to multiple hot pressing forming stages respectively; generating video identifiers of key video data corresponding to multiple hot pressing forming stages respectively according to the adjustment of real-time hot pressing control parameters corresponding to the multiple hot pressing forming stages, and the video identifiers are used to characterize the changes in the hot pressing control parameters of the corresponding hot pressing forming stages; generating a hot pressing forming learning video according to the video data, key video data and video identifiers corresponding to the multiple hot pressing forming stages respectively; and feeding back the hot pressing forming learning video to the user end, so that the user of the user end can learn hot pressing forming knowledge based on the hot pressing forming learning video.

[0103] The key video data corresponding to the multiple hot pressing forming stages may be a start video frame, an end video frame and an intermediate video frame. The intermediate video frame may be a video frame where a state change occurs.

[0104] In some embodiments, the video identifiers of the key video data corresponding to the multiple hot pressing forming stages may be in the form of a graph or a table, which may represent the change of the parameters.

[0105] Taking the change curve graph as an example, if a parameter has not been adjusted, the change curve of the parameter is a line segment with a constant value. If a parameter has been increasing, the change curve of the parameter is a line segment with a slope.

[0106] Furthermore, according to the video data, key video data and video identifiers corresponding to the multiple hot press forming stages, a hot press forming learning video can be generated. For example, in the hot press forming learning video, a video identifier is added to the key video data, and when the video frame is played, the video identifier is also displayed accordingly.

[0107] For example, if it is a change curve, the change curve can be dynamically displayed according to the change mode of the change curve during the playback time of the video frame.

[0108] In addition, for some video frames, for example, the starting video frame of a stage, text identification information for introducing the stage can be added. For the ending video frame of a stage, identification information for summarizing the stage can also be added, for example, identification information for describing the final effect.

[0109] Then, the hot press forming learning video is fed back to the user end, so that the user at the user end can learn the hot press forming knowledge based on the hot press forming learning video. Therefore, the user can not only learn the operation method of each stage of hot press forming, but also learn the parameter adjustment method of each stage.

[0110] It can be seen from the introduction of the embodiments of the present invention that the technical solution can improve the quality of film formation: by precisely controlling the hot pressing parameters, the uniformity and quality of the film formation can be significantly improved. Optimize production efficiency: adjust parameters in real time to reduce ineffective time and resource waste in production. Enhance system stability: the closed-loop control system ensures the stability and repeatability of the film formation process. Reduce manual dependence: reduce dependence on operator experience and improve the level of production automation.
