[0062] In the related art, especially in the step of curing the paint layer, the paint layer may partially volatilize due to environmental factors (for example, changes in air humidity, changes in air temperature) or poor heat dissipation of the equipment, which in turn leads to a mismatch between the set drying time and drying temperature and the partially volatilized paint layer, causing the curing effect of the painting equipment on the partially volatilized paint layer to become greater or lesser, thereby causing the internal stress of the paint layer of the enameled wire to increase, resulting in cracking of the paint layer, or incomplete curing, resulting in the paint layer falling off, and ultimately leading to problems such as a decline in the quality of the enameled wire products and a decrease in production efficiency.
[0063] To solve the above problems, an embodiment of the present application provides a method for painting an enameled wire. In the method, a drying temperature for reflecting the set temperature when drying the paint layer of the enameled wire and a drying time for reflecting the duration of the enameled wire at the drying temperature are first obtained, and then the drying parameters are analyzed to obtain a first temperature change image for reflecting the actual temperature change image of the enameled wire under the drying parameters, a surface image for reflecting the enameled wire at the drying temperature, and a second temperature change image for reflecting the temperature change image of the standard paint layer when the standard paint layer is dried under the drying parameters, and then according to the surface image, the drying parameters, the first temperature change image and the second temperature change image, an analysis is performed to obtain an adjusted temperature for reflecting the adjusted drying temperature and an adjusted time for reflecting the adjusted drying time, and finally, based on the adjusted temperature and the adjusted time, the control device controls the painting equipment to adjust the drying temperature to the adjusted temperature and the drying time to the adjusted time.
[0064] The enameled wire painting method provided in the embodiment of the present application can be applied to the enameled wire painting equipment. In this case, the enameled wire painting equipment is the executor of the enameled wire painting method provided in the embodiment of the present application. The embodiment of the present application does not impose any restrictions on the specific type of the enameled wire painting equipment.
[0065] The enameled wire painting equipment includes a painting device and a control device. The painting device is electrically connected to the control device. The painting device is used to heat and cure the paint layer of the enameled wire. For example, the painting device includes a heating mechanism and a detection mechanism. The heating mechanism is used to heat and cure the paint layer. For example, the heating mechanism can be a hot air dryer or an infrared curing furnace. The detection mechanism is used to detect the drying temperature and drying time of the paint layer and obtain the surface image of the paint layer. For example, the detection mechanism includes a temperature sensor, an image collector and a timer. The temperature sensor is used to detect the temperature of the paint layer. For example, the temperature sensor can be an infrared temperature sensor or an optical fiber temperature sensor. The image collector is used to collect the surface image of the paint layer. For example, the image collector can be an electron microscope, an infrared thermal imaging camera or a digital camera. The timer is used to time the duration of the drying temperature. For example, the timer can be an electronic timer, a digital timer or a mechanical clock. The control device is used to supervise and control the enameled wire painting process.
[0066] For example, the control device can be a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a smart large screen, a smart TV, a handheld device with wireless communication function, a desktop computer, a handheld device with wireless communication function, a computer, a laptop computer, a handheld computing device, etc.
[0067] In order to better understand the method for painting the enameled wire provided in the embodiment of the present application, the specific implementation process of the method for painting the enameled wire provided in the embodiment of the present application is exemplarily introduced below.
[0068] Figure 1 and Figure 2 A schematic flow chart of the method for painting an enameled wire provided in an embodiment of the present application is shown. Figure 1 and Figure 2 , the enameled wire painting methods include:
[0069] S100, obtaining drying parameters; wherein the drying parameters include drying temperature and drying time, the drying temperature is used to reflect the set temperature when drying the paint layer of the enameled wire, and the drying time is used to reflect the duration of the enameled wire at the drying temperature.
[0070] It can be understood that when the enameled wire is transported to the curing mechanism for curing, the curing stage of the enameled wire is usually to first raise the temperature of the enameled wire to the drying temperature, and then keep the enameled wire raised to the drying temperature at this temperature for a preset holding time to complete the curing of the enameled wire. The preset holding time refers to the insulation time of the enameled wire when it reaches the drying temperature during the drying time. The duration refers to the total time for the paint layer to complete the curing stage at the set drying temperature.
[0071] Exemplarily, the drying parameters can be manually input. The drying parameters can also be directly obtained through the curing database. The curing database refers to a database containing the drying time and drying temperature corresponding to different paint liquid states. These data can be obtained through laboratory experiments, on-site measurements and monitoring, and past experience. After obtaining, the collected data is sorted, classified and archived, useful information and rules are extracted, and the relevant data is saved in the database to form a curing database.
[0072] S200, obtaining a first temperature change image, a surface image and a second temperature change image; wherein the first temperature change image is used to reflect the actual temperature change image of the enameled wire under the drying parameters, the surface image is used to reflect the surface color image of the enameled wire under the drying temperature, and the second temperature change image is used to reflect the temperature change image of the standard paint layer when the standard paint layer is dried under the drying parameters.
[0073] It can be understood that the standard paint layer refers to the paint layer of the non-volatile enameled wire when it is dried under the drying parameters.
[0074] Exemplarily, the second temperature change image can be obtained by manual input. The second temperature change image can also be directly obtained through an image database. An image database refers to a database containing temperature change graphs of the paint layer surface corresponding to different drying parameters. These data can be obtained through laboratory experiments, on-site measurements and monitoring, and previous experience. After obtaining, the collected data is sorted, classified and archived, useful information and rules are extracted, and the relevant data is saved in the database to form an image database. The surface temperature of the paint layer can be obtained in real time through a temperature sensor and drawn through drawing software, and finally the first temperature change image is obtained. When the temperature of the paint layer reaches the drying temperature, the temperature sensor sends a start signal to the image collector, and the image collector takes a picture of the surface of the paint layer to obtain the surface image of the paint layer.
[0075] S300, analyzing the surface image, the drying parameters, the first temperature change image and the second temperature change image to obtain the adjustment temperature and the adjustment time; wherein the adjustment temperature is used to reflect the set temperature when the paint layer of the enameled wire is dried after adjustment, and the adjustment time is used to reflect the duration of the enameled wire at the adjustment temperature.
[0076] For example, the color state of the paint layer surface when the paint layer reaches the drying temperature can be analyzed by analyzing the surface image, and the difference between the color state of the paint layer surface when the paint layer reaches the drying temperature and the preset color state can be obtained. Finally, the difference, the drying parameter, the first temperature change graph, and the second change graph can be analyzed to obtain the adjustment temperature and the adjustment time. The color state refers to the color presentation of the paint layer surface when the paint layer temperature reaches the drying temperature.
[0077] The adjustment temperature and adjustment time can also be obtained through the analysis model, that is, the surface image, the drying parameters, the first temperature change image and the second temperature change image are input into the analysis model, and the analysis model then outputs the corresponding adjustment temperature and adjustment time. The training process of the analysis model can be performed by processing the surface image, the drying parameters, the first temperature change image and the second temperature change image, and the corresponding adjustment temperature and adjustment time as the training data set of the analysis model, and then the training data set of the analysis model is input into the analysis model for training and learning, and finally the analysis model is obtained.
[0078] In a possible implementation, in step S300, analyzing the surface image, the drying parameters, the first temperature change image, and the second temperature change image to obtain the adjustment temperature and the adjustment time includes:
[0079] S310, analyzing the surface image to obtain a color difference; wherein the color difference is used to reflect the difference between the surface image and a preset color value, and the preset color value refers to the color value of the surface of the enameled wire when the non-volatile enameled wire is dried under the drying parameters and reaches the drying temperature.
[0080] It can be understood that color value refers to a specific numerical value that describes the color. The standard color value refers to the color value of the paint layer when it reaches the drying temperature when the standard paint layer is cured under the drying parameters. The preset color value can be manually input. The preset color value can also be directly obtained through the color database. The color database refers to a database containing the color values of the surface of the standard paint layer corresponding to different drying parameters. These data can be obtained through laboratory experiments, on-site measurements and monitoring, and past experience. After obtaining, the collected data will be sorted, classified and archived, useful information and rules will be extracted, and the relevant data will be saved in the database to form a color database.
[0081] For example, the surface image may be processed to obtain a plurality of color values, and then the plurality of color values may be averaged to obtain an average value between the plurality of color values, and finally the color difference may be obtained by comparing the average value between the plurality of color values with a preset color value.
[0082] It is also possible to obtain multiple color values by processing the surface image, and then match the color value with a preset interval set and obtain the number of matches corresponding to each interval in the preset interval set, and then compare the number of matches corresponding to each interval with the total number of color values to obtain the color weight corresponding to each interval, and then perform mean calculation on multiple color values falling into each interval to obtain the color mean corresponding to each interval, and finally compare the color value obtained by weighted summation of the color mean corresponding to each interval and the corresponding color weight with the preset color value, and finally obtain the color difference. The preset interval set includes multiple preset intervals. The preset interval refers to a preset color value interval. The total number of color values refers to the total number of color values obtained after processing the surface image. Color weight = number of matches ÷ total number of color values.
[0083] In a possible implementation, in step S310, analyzing the surface image to obtain a color difference value includes:
[0084] S311, processing the surface image to obtain a plurality of color values; wherein the color values are used to reflect different characteristics of the color of the surface image.
[0085] It can be understood that the surface image can be converted from RGB color space to HSV, Lab or other color space by using the cv2.cvtColor function in the Python code, and then pixel analysis is performed on the converted surface image and multiple color values in the surface image are recorded. Pixel analysis refers to the process of analyzing each pixel in the image. Pixels are the basic units that make up a digital image, and each pixel has a specific color value (value in a color space such as RGB or HSV).
[0086] S312, performing mean operation on the multiple color values to obtain a color mean; wherein the color mean is used to reflect the average value among the multiple color values.
[0087] For example, if the color values of the pixels in the surface image are 122, 168, 154, 222, and 97 respectively, the color mean is 152.6 [(122+168+154+222+97)÷5], and so on.
[0088] S313, comparing the color mean value with the preset color value to obtain a color difference value.
[0089] It can be understood that color difference = color mean value - preset color value. For example, if the color mean value is 125 and the preset color value is 125, the color difference value is 0 (125-125); if the color mean value is 155 and the preset color value is 125, the color difference value is 30 (155-125); if the color mean value is 156 and the preset color value is 180, the color difference value is -24 (156-180), and so on.
[0090] With this setting, by performing the mean calculation on the extracted multiple color values, a value reflecting the overall level of these color values can be obtained. The color mean can be used to represent the color attribute of the paint layer surface image. By comparing the color mean with the preset color value, the color difference obtained can be used to judge the difference between the color in the image and the preset standard. By calculating the color difference, the judgment process of color difference can be simplified, and it can be quickly determined whether the paint layer state meets the preset standard.
[0091] S320, analyzing according to the color difference, the drying parameters, the first temperature change graph and the second temperature change graph to obtain an adjustment temperature and an adjustment time.
[0092] It can be understood that the color difference can reflect the state of the paint layer when it reaches the drying temperature. The drying temperature can be judged by the color difference. When the color difference is equal to 0, it means that the state of the paint layer when it reaches the drying temperature is equivalent to that of the standard paint layer at the drying temperature, and the drying temperature does not need to be adjusted. Then, according to the drying temperature, the first temperature change graph and the second stable change graph, an analysis is performed to obtain the difference between the time when the drying temperature is reached in the first temperature change graph and the time when the drying temperature is reached in the second temperature change graph. Finally, the adjustment time is obtained by analyzing the drying time and the difference. When the color difference is not equal to 0, the first temperature change graph is processed to obtain an image reflecting the continuous rise of the temperature in the first temperature change graph. Then, according to the second temperature change graph, an analysis is performed to obtain the total heat reflecting the continuous rise of the temperature in the second temperature change graph. Finally, the adjustment temperature and adjustment time are obtained by analyzing the second temperature change graph, the total heat when the temperature continues to rise in the second temperature change graph, and the image when the temperature continues to rise in the first temperature change graph.
[0093] A prediction model can also be established by selecting a suitable machine learning algorithm. The prediction model inputs the color difference, drying parameters, the first temperature change graph and the second temperature change graph, and then outputs the adjustment temperature and adjustment time. The types of prediction models include but are not limited to linear regression, decision tree, random forest and support vector machine (SVM) models. The training process of the prediction model can be to analyze the color difference, drying parameters, the first temperature change graph and the second temperature change graph, and process the corresponding adjustment temperature and adjustment time as the training data set of the prediction model, and then input the training data set of the prediction model into the prediction model for training and learning, and finally obtain the prediction model.
[0094] With this setup, the heat treatment process can be optimized by analyzing the color difference of the surface image to ensure that the performance of the paint layer meets the expected requirements. By analyzing the color difference and temperature change graph, the optimal drying temperature and time can be determined to ensure product quality.
[0095] In a possible implementation, in step S320, analyzing the color difference, the drying parameters, the first temperature change graph, and the second temperature change graph to obtain the adjustment temperature and the adjustment time includes:
[0096] S321, when the color difference is equal to 0, the drying temperature is confirmed as the adjustment temperature.
[0097] It can be understood that when the color difference is equal to 0, it means that the heat absorbed by the paint layer before the temperature continues to rise to the drying temperature is the same as the heat absorbed by the standard paint layer before the temperature continues to rise to the drying temperature, that is, the state of the paint layer when it reaches the drying temperature is equivalent to that of the standard paint layer at the drying temperature, so there is no need to adjust the already set drying temperature.
[0098] S322, analyzing the drying temperature, the first temperature change graph and the second temperature change graph to obtain a time difference; wherein the time difference is used to reflect the difference between the time when the drying temperature is reached in the first temperature change graph and the time when the drying temperature is reached in the second temperature change graph.
[0099] It can be understood that when the paint layer partially evaporates due to environmental factors (for example, changes in air humidity, changes in air temperature) or poor heat dissipation of the equipment, the insulating paint concentration of the paint layer increases, causing the temperature change rate in the first temperature change graph to be smaller than the temperature change rate in the second temperature change graph, thereby prolonging the time for the paint layer to reach the drying temperature.
[0100] Exemplarily, the first temperature change graph and the drying temperature can be analyzed to obtain the time when the drying temperature is reached in the first temperature change graph, and then the second temperature change graph and the drying temperature can be analyzed to obtain the time when the drying temperature is reached in the second temperature change graph. Finally, the time when the drying temperature is reached in the first temperature change graph is compared with the time when the drying temperature is reached in the second temperature change graph to obtain the time difference.
[0101] The timer can also start timing when it receives the start signal from the temperature sensor when it starts working, and end timing when the temperature sensor detects the end signal sent when the paint layer reaches the drying temperature. The time obtained is compared with the preset time value to obtain the time difference. The preset time value is the time when the preset standard paint layer reaches the drying temperature. The preset time value can be manually input. The preset time value can also be directly obtained through the time database. The time database refers to a database containing the time to reach the drying temperature corresponding to different paint liquid states. These data can be obtained through laboratory experiments, on-site measurements and monitoring, and previous experience. After obtaining, the collected data will be sorted, classified and archived, useful information and rules will be extracted, and the relevant data will be saved in the database to form a time database.
[0102] In a possible implementation, in step S322, analyzing the drying temperature, the first temperature change graph, and the second temperature change graph to obtain the time difference includes:
[0103] S3221, analyzing the first temperature change graph and the drying temperature to obtain a first time; wherein the first time is used to reflect the time when the drying temperature is reached in the first temperature change graph.
[0104] It is understandable that the first temperature change graph can be matched with the drying temperature to obtain the time point when the drying temperature is first reached in the first temperature change graph, and the time corresponding to the time point in the first temperature change graph can be obtained, which is the first time.
[0105] S3222, analyzing the second temperature change graph and the drying temperature to obtain a second time; wherein the second time is used to reflect the time when the drying temperature is reached in the second temperature change graph.
[0106] It is understandable that the time point at which the drying temperature is first reached in the second temperature change graph can be obtained by matching the second temperature change graph with the drying temperature, and the time corresponding to the time point in the second temperature change graph can be obtained as the second time.
[0107] S3223, obtaining a time difference by comparing the first time with the second time; wherein the time difference is used to reflect the difference between the first time and the second time.
[0108] It can be understood that because the temperature change rate in the first change graph is less than the temperature change rate in the second temperature change graph, the first time is greater than the second time. Time difference = first time - second time. For example, if the first time is 34s and the second time is 25s, the time difference is 9 (34s - 25s)s, and so on.
[0109] With this arrangement, by comparing the time it takes for the paint layer to reach the drying temperature with that of the standard paint layer, the difference between the paint layer and the standard paint layer during the continuous temperature rise stage can be evaluated, thereby optimizing the drying parameters, and ultimately more accurately controlling and adjusting the drying parameters.
[0110] S323, performing processing according to the drying time and the time difference to obtain an adjustment time.
[0111] It can be understood that the drying time is divided into temperature rise time and heat preservation time. From step S321, it can be understood that the heat absorbed by the paint layer before the temperature continues to rise to the drying temperature is the same as the heat absorbed by the standard paint layer between the temperature continues to rise to the drying temperature, and the paint layer and the standard paint layer need to reach the same state in the end, that is, the heat required for the paint layer to complete the curing is the same as the heat required for the standard paint layer to complete the curing. It can be explained that when the color difference is 0, the heat preservation time of the paint layer is the same as the heat preservation time of the standard paint layer, then the adjustment time = heat preservation time + first time = drying time - second time + first time, that is, the adjustment time = drying time + time difference. Exemplarily, for example, if the drying time is 25s and the time difference is 5s, the adjustment time is 30(25s+5s)s, and so on.
[0112] With such a configuration, during the enameled wire painting process, when the paint layer color meets the standard, the current drying temperature can be directly used without adjustment. By analyzing the first temperature change graph and the second temperature change graph, the difference in time required to reach the drying temperature between the first temperature change graph and the second temperature change graph can be obtained. By analyzing the time difference between the first temperature change graph and the second temperature change graph, the time difference required to reach the same drying temperature under different conditions of volatilization and non-volatilization of the paint layer can be reflected. According to the time difference, the drying process is optimized to improve production efficiency and consistency of product quality.
[0113] In a possible implementation, in step S320, analyzing the color difference, the first temperature change graph, and the second temperature change graph to obtain the adjustment temperature and the adjustment time further includes:
[0114] S324, when the color difference is not equal to 0, segment the first temperature change graph to obtain a rising graph; wherein the rising graph is used to reflect an image when the temperature in the first temperature change graph continues to rise.
[0115] It can be understood that when the color difference is not equal to 0, it can be explained that the heat absorbed by the paint layer when the temperature continues to rise to the drying temperature is different from the heat absorbed by the standard paint layer when the temperature continues to rise to the drying temperature, that is, the state of the paint layer when it reaches the drying temperature is different from that of the standard paint layer at the drying temperature, and the drying temperature that has been set needs to be adjusted. By performing image segmentation on the first temperature change graph, a graph in which the temperature is continuously rising in the first temperature change graph, that is, a rising graph, can be obtained. Image segmentation refers to the process of dividing the first temperature image into multiple non-overlapping areas or parts. The drying temperature can be selected as the segmentation anchor point and the first temperature image can be segmented to obtain a rising graph. The first temperature image can also be segmented to obtain a rising graph by using a point with a temperature change rate of 0 as a separation anchor point. Then through
[0116] S325, analyzing the second temperature change graph to obtain a rising heat value; wherein the rising heat value is used to reflect the total heat when the temperature in the second temperature change graph continues to rise.
[0117] It can be understood that the area of the second temperature change graph in the stage of continuous temperature rise can be obtained by performing an integral operation on the second temperature change graph, that is, the rising heat value. The integral operation is used to calculate the accumulated area value of the second temperature change graph in the second time, that is, the rising heat value. The integral operation formula is: Wherein Q1 is the rising heat value, t2 is the second time, and F1(x) is the second temperature change diagram.
[0118] S326, analyzing the second temperature change graph, the rising heat value and the rising graph to obtain the adjustment temperature and the adjustment time.
[0119] Exemplarily, the rising graph and the rising calorific value can be integrated to obtain the time reflecting the continuous rise in temperature during the adjustment time, and then the time reflecting the continuous rise in temperature during the adjustment time is matched with the rising graph to obtain the adjusted temperature. Finally, the adjusted temperature, the second temperature change graph and the time reflecting the continuous rise in temperature during the adjustment time are analyzed to obtain the adjusted time.
[0120] It is also possible to perform integral operation on the rising graph to obtain the heat of the rising image, and then compare the heat of the rising graph with the rising heat value to obtain the heat difference, and then analyze the heat difference with the rising graph to obtain the adjusted rising time, and then match the adjusted rising time with the rising graph to obtain the adjusted temperature, and finally analyze the adjusted temperature, the second temperature change graph and the adjusted rising time to obtain the adjusted time. The adjusted rising time refers to the time it takes for the temperature of the paint layer to reach the adjusted temperature after adjustment. The heat difference refers to the difference between the heat of the rising graph and the rising heat value.
[0121] In this way, when the color difference is not equal to 0, it can be said that there is a difference between the state of the paint layer when it reaches the drying temperature and the state of the standard paint layer at the drying temperature. At this time, the first temperature change graph is segmented, and the part where the temperature continues to rise is extracted. By controlling the calorific value, it can be ensured that the drying state between the paint layer and the standard paint layer is equivalent, which can better control and improve production efficiency and the consistency of enameled wire quality.
[0122] In a possible implementation, in step S326, analyzing the second temperature change graph, the rising heat value and the rising graph to obtain the adjustment temperature and the adjustment time includes:
[0123] S3261, performing an integral operation on the rising graph and the rising heat value to obtain a third time; wherein the third time is used to reflect the time during which the temperature continues to rise during the adjustment time.
[0124] It can be understood that when the paint layer is curing, the heat required to keep the paint layer in the temperature rising stage is the same as the heat required when the standard paint layer temperature rises to the drying temperature. This can ensure that the paint layer is in the same state as the standard paint layer when it starts to be heat-insulated, and can better cure the paint layer according to the preset state, thereby improving the stability of the painting process.
[0125] For example, the accumulated time of the rising heat value, that is, the third time, can be obtained by using the integral operation in the integral operation. The calculation process of the third time can be similar to the method of obtaining the rising heat value in step S325 to obtain the third time, which will not be repeated here.
[0126] S3262, matching the third time with the rising graph to obtain a matching temperature in the rising graph at the third time, and determining the matching temperature as the adjustment temperature.
[0127] It can be understood that the point corresponding to the third time can be found in the rising graph, and the matching temperature corresponding to the point in the rising graph at the third time can be obtained, and finally the matching temperature can be confirmed as the adjustment temperature.
[0128] S3263, analyzing the adjustment temperature, the second temperature variation graph and the third time to obtain the adjustment time.
[0129] Exemplarily, the second temperature change graph can be analyzed to obtain the total heat reflecting the temperature when the second temperature change graph remains unchanged, and then the adjustment time can be obtained based on the total heat reflecting the temperature when the second temperature change graph remains unchanged, the third time and the adjusted temperature.
[0130] The adjustment time can also be obtained by analyzing the time analysis model, that is, the adjustment temperature, the second temperature change graph and the third time are input into the analysis model, and the time analysis model then outputs the corresponding adjustment time. The training process of the time analysis model can be performed by using the data processed from the adjustment temperature, the second temperature change graph and the third time and the corresponding adjustment time as the training data set of the time analysis model, and then inputting the training data set of the time analysis model into the analysis model for training and learning, and finally obtaining the time analysis model.
[0131] With this setting, through integral operation, the time of continuous temperature rise can be accurately calculated to ensure the accuracy of the optimized adjustment time. Then, by matching the temperature values in the rising graph, the accuracy of the adjusted temperature can be ensured. Finally, by analyzing the adjustment stability, the second temperature change graph and the third time, a comprehensive analysis can be performed to obtain the optimized adjustment time in the drying process, thereby ensuring product quality.
[0132] In a possible implementation, in step S3263, analyzing the adjustment temperature, the second temperature variation graph, and the third time to obtain the adjustment time includes:
[0133] S32631, analyzing according to the second temperature change graph to obtain a stable calorific value; wherein the stable calorific value is used to reflect the total heat when the temperature in the second temperature change graph remains unchanged.
[0134] It can be understood that the stable calorific value refers to the total amount of heat continuously absorbed by the standard paint layer at the drying temperature and the holding time in the second temperature change graph. For example, the stable calorific value can be obtained in a manner similar to the rising calorific value obtained in step S325, which will not be described in detail here. The second temperature change graph can also be analyzed to obtain the holding time when the temperature remains unchanged in the second temperature change graph, and then the stable calorific value is obtained by multiplying the holding time when the temperature remains unchanged in the second temperature change graph with the drying temperature.
[0135] S32632, performing processing according to the stable heat value, the third time and the adjustment temperature to obtain the adjustment time.
[0136] It is understood that the stable calorific value and the adjusted temperature can be processed to obtain a duration reflecting that the temperature remains unchanged during the adjustment time. Then, the time and are calculated by summing the duration reflecting that the temperature remains unchanged during the adjustment time and the third time, and finally the time and are confirmed as the adjustment time. The time and are the sum of the duration reflecting that the temperature remains unchanged during the adjustment time and the third time.
[0137] In this way, by controlling the heat required for the paint layer to be consistent with that of the standard paint layer during insulation, it is possible to ensure that the paint layer reaches the same temperature as the standard paint layer during the insulation process, and to avoid inconsistent paint quality due to temperature differences, thereby improving product quality consistency and ensuring that the color and performance of the paint layer are consistent with the standard paint layer, improving the appearance and performance quality of the finished product, and by precisely controlling the temperature, it is possible to reduce rework caused by inconsistent temperatures and improve production efficiency. By precisely controlling the heat during the insulation process, overheating or underheating can be avoided, thereby optimizing energy use and reducing production costs.
[0138] In a possible implementation, in step S32632, processing is performed according to the stable heat value, the third time and the adjustment temperature to obtain the adjustment time, including:
[0139] S326321, processing is performed according to the stable calorific value and the adjusted temperature to obtain a fourth time; wherein the fourth time is used to reflect the duration of the unchanged temperature during the adjusted time.
[0140] It can be understood that the calculation formula for the fourth time can be Wherein Q is the stable calorific value, t4 is the fourth time, and T is the adjusted temperature. For example, if the stable calorific value is 1000 J and the adjusted temperature is 50° C., the fourth time is 20 seconds, and so on.
[0141] S326322, sum the third time and the fourth time to obtain time and, and confirm the time and, as the adjusted time.
[0142] It can be understood that the time and = the third time + the fourth time. For example, if the third time is 20s, the fourth time is 20s, and the time and is 40(20s+20s)s, then the adjustment time is 40s, and so on.
[0143] In this way, by controlling the insulation time of the paint layer and the standard paint layer so that the heat required for the paint layer and the standard paint layer is consistent, the consistency of the physical properties, electrical properties and appearance during the production of the enameled wire can be ensured, and the production cost can be reduced.
[0144] S400, the control device adjusts the drying temperature to the adjusted temperature, and adjusts the drying time to the adjusted time.
[0145] For example, if the drying temperature is 50°C, the drying time is 5 minutes, the adjustment temperature is 56°C, and the adjustment time is 6 minutes, then the drying temperature of 50°C in the drying parameters is adjusted to 56°C, and the drying time of 5 minutes in the detection conditions is adjusted to 6 minutes, and so on.
[0146] With such a setting, it is possible to effectively obtain in real time the drying temperature and drying time that are suitable for the partially volatilized paint layer based on the difference between the first temperature change graph obtained for the enameled wire under the initially set drying parameters and the second temperature change graph obtained for the standard paint layer under the initially set drying parameters. By targetedly adjusting the drying temperature and drying time of the current enameled wire, the quality of the enameled wire product can be improved.
