[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0029] See also Figures 1 to 8, a thermal transfer method of a thermal transfer printer, applied to the thermal transfer scene of the thermal transfer printer; the thermal transfer method of the thermal transfer printer includes:
[0030] Step S11: collecting pictures, and determining the thermal transfer area of the pictures according to the recognition of the pictures;
[0031] Step S12: determining a position calibration sub-area according to the thermal transfer area of the image and the moving system of the thermal transfer head;

[0033] Step S14: determining the thermal transfer logic of the thermal transfer head based on the heating sub-area, the calibration sub-area and the image;
[0034] Step S15: in the thermal transfer logic of the thermal transfer head, primary thermal transfer is performed on the heating sub-area, and multi-level temperature compensation logic is performed in the primary thermal transfer of the heating sub-area; a temperature distribution map of the heating sub-area is determined based on the heating sub-area and the corresponding temperature data;
[0035] Step S16: Determine the moving route of the thermal transfer head based on the temperature distribution map of the heating sub-area, the calibration sub-area and the thermal transfer head, determine multiple detection areas according to the moving route of the thermal transfer head and the thermal transfer area of the image, and match the corresponding thermal transfer optimization events according to the printing effect level of each detection area and the area of each detection area.
[0036] refer to Figure 2 , in step S11, a picture is collected, and a thermal transfer area of the picture is determined based on the recognition of the picture;
[0037] In the specific implementation process of the present invention, the specific steps may be:
[0038] S111: real-time monitoring of the thermal transfer data space of the thermal transfer printer;
[0039] S112: determining a picture according to the thermal transfer data space of the thermal transfer printer, and collecting the picture, which is used as a material for subsequent thermal transfer;
[0040] S113: recognizing the image, and determining a plurality of patterns according to the recognition of the image;
[0041] S114: Input multiple patterns, outer boundaries of pictures and blank areas into the corresponding recognition learning model, and output the thermal transfer area of the picture according to the recognition learning model. At this time, the recognition learning model is trained based on previous patterns, pictures and blank areas.
[0042] In an embodiment of the present application, the thermal transfer data space of the thermal transfer printer is monitored in real time; a picture is determined based on the thermal transfer data space of the thermal transfer printer, and the picture is collected. The picture is used as material for subsequent thermal transfer, and the thermal transfer data space of the thermal transfer printer is introduced. The thermal transfer data space of the thermal transfer printer is further controlled to ensure real-time acquisition of the picture.
[0043] Specifically, the thermal transfer data space refers to all the data sets involved in the printing process of the thermal transfer printer, including images, printing parameters (such as temperature, speed, pressure), equipment status (such as print head temperature, carbon ribbon tension), print task queue, etc. By real-time monitoring of these data, the corresponding pictures can be obtained. At the same time, by real-time monitoring of image data, the thermal transfer printer can automatically adjust the printing parameters according to the complexity of the image. For example, for high-resolution color images, the printer can reduce the printing speed and increase the temperature to ensure the printing quality.
[0044] In the thermal transfer printing process, "images as materials for subsequent thermal transfer" refers to images obtained in some way (such as real-time monitoring data, preset images, or user-entered images), which are stored and used for subsequent thermal transfer printing tasks. These images can be text, patterns, photos, or other graphic content, and they are the core input data in the thermal transfer process.
[0045] Furthermore, the image is recognized, and multiple patterns are determined based on the recognition of the image; the multiple patterns, outer boundaries of the image, and blank areas are input into the corresponding recognition learning model, and the thermal transfer area of the image is output according to the recognition learning model. At this time, the recognition learning model is trained based on previous patterns, images, and blank areas, and multiple patterns, outer boundaries of the image, and blank areas are introduced. Multiple patterns, outer boundaries of the image, and blank areas are trained accordingly in the recognition learning model, and corresponding results are output based on the recognition learning model. The result is the thermal transfer area of the image, which is compatible with the overall consideration of multiple patterns, outer boundaries of the image, and blank areas, and realizes multi-dimensional control of multiple patterns, outer boundaries of the image, and blank areas, thereby ensuring the accuracy of the thermal transfer area of the image.
[0046] Specifically, the image is autonomously recognized to identify multiple patterns in the image. For example, an image containing multiple independent patterns can be decomposed into multiple independent thermal transfer objects. These patterns can be text, graphics, or complex designs. During the recognition process, not only the pattern itself is recognized, but also the outer boundaries of the pattern and the blank areas in the image are detected. This information is crucial for the subsequent thermal transfer area division because they can help determine which parts need to be printed and which parts need to be retained.
[0047] At the same time, the recognition learning model is trained based on previous patterns, pictures, and blank areas. The training data includes multiple previous patterns, the outer boundaries of pictures, and blank areas. The pattern is the image content that needs to be printed and is the main object of thermal transfer. The outer boundary is the outline of the pattern, which is used to determine the range of the pattern. The blank area is the background area that does not need to be printed, which is used to optimize the printing path and improve the printing quality. At this time, by identifying the outer boundary of the picture, the area that needs to be printed is determined. According to the shape of the pattern and the distribution of the blank area, the movement path of the thermal transfer head is planned to improve printing efficiency. By distinguishing between patterns and blank areas, it is avoided to print in places that do not need to be printed, and the waste of ink or carbon ribbon is reduced.
[0048] For the training of recognition learning models, a large amount of labeled data is required, including patterns, outer boundaries, and blank areas. These data can be obtained from previous thermal transfer tasks; before training, the data needs to be preprocessed; the patterns, outer boundaries, and blank areas are converted into a format acceptable to the model, such as the YOLO format. At this time, the data set is divided into a training set and a validation set, usually with a ratio of 80% training set and 20% validation set. Load the pre-trained model or start training from scratch, set hyperparameters such as learning rate, batch size, and learning rate decay, use the training set data to train the model, and evaluate the model performance on the validation set to gradually form a recognition learning model.
[0049] refer to Figure 3 , in step S12, determining the position calibration sub-area according to the thermal transfer area of the image and the moving system of the thermal transfer head;
[0050] In the specific implementation process of the present invention, the specific steps may be:
[0051] S121: Obtaining a thermal transfer area of the image;
[0052] S122: Traversing the thermal transfer printer, and determining the thermal transfer head and the multi-dimensional moving module according to the traversal of the thermal transfer printer;
[0053] S123: determining a moving system of the thermal transfer head based on a thermal transfer range of the thermal transfer head and a moving range of the multi-dimensional moving module;
[0054] S124: performing multi-dimensional interaction on a thermal transfer area of the image and a moving system of a thermal transfer head;
[0055] S125: Determine a position calibration sub-area according to the thermal transfer area of the image and multiple interactions of the moving system of the thermal transfer head.
[0056] In an embodiment of the present application, the thermal transfer area of the image is obtained; the thermal transfer printer is traversed, and the thermal transfer head and the multi-dimensional movable module are determined according to the traversal of the thermal transfer printer; the moving system of the thermal transfer head is determined based on the thermal transfer range of the thermal transfer head and the moving range of the multi-dimensional movable module, which is compatible with the overall consideration of the thermal transfer range of the thermal transfer head and the moving range of the multi-dimensional movable module, realizes multi-dimensional control of the thermal transfer range of the thermal transfer head and the moving range of the multi-dimensional movable module, and ensures the accuracy of the moving system of the thermal transfer head.
[0057] At this time, the thermal transfer area of the image refers to the part of the image that needs to be transferred from the thermal transfer paper to the target medium (such as T-shirts, cups, label paper, etc.). At the same time, in a thermal transfer printer, "traversal" usually refers to the various components inside the printer (such as thermal transfer heads, conveyor rollers, multi-dimensional moving modules, etc.).
[0058] The thermal transfer head is the core component of the thermal transfer printer, responsible for transferring the ink on the carbon ribbon to the target medium. During the traversal process, the position and state of the thermal transfer head need to be accurately detected and calibrated; the thermal transfer head needs to switch between the engagement position (pressed on the conveyor roller) and the separation position (separated from the conveyor roller). The engagement position is used for printing, and the separation position is used to replace the carbon ribbon or medium; the heating element of the thermal transfer head ensures that the ink can be accurately transferred to the target medium by precisely controlling the temperature and pressure.
[0059] The multi-dimensional mobile module is used to control the movement of the thermal transfer head to ensure that it can accurately cover the entire printing area during the printing process. During the traversal process, the range and accuracy of the mobile module need to be calibrated: the thermal transfer head usually moves along the X-axis (horizontal direction) and the Y-axis (vertical direction) to cover the entire printing area. In some cases, the thermal transfer head also needs to move along the Z-axis (perpendicular to the printing plane) to adjust the distance from the target medium. For printed objects with curved surfaces or irregular shapes, the mobile module may need to support rotation.
[0060] At this time, the thermal transfer range of the thermal transfer head refers to the printing area it can cover, which is usually determined by the physical size and resolution of the thermal transfer head. For example, the thermal transfer head may have a fixed printing width and length, and its resolution determines the fineness of the printing; the multi-dimensional movement module is used to control the movement of the thermal transfer head to ensure that it can cover the entire printing area.
[0061] The movement system of the thermal transfer head is realized by combining the thermal transfer range of the thermal transfer head and the movement range of the multi-dimensional moving module. The specific steps are as follows: when starting the thermal transfer printer, the system will perform an initialization test to determine the initial position and state of the thermal transfer head and the moving module; through the sensor and control system, the movement range of the thermal transfer head on the X-axis, Y-axis and Z-axis is determined. For example, the movement range of the thermal transfer head can be accurately measured by a limit switch or an encoder; according to the thermal transfer range of the thermal transfer head and the movement range of the moving module, the movement parameters of the thermal transfer head are adjusted to ensure that it can cover the entire printing area. For example, by adjusting the driving current or speed of the motor, the movement speed and accuracy of the thermal transfer head can be optimized; during the printing process, the position of the thermal transfer head is monitored in real time by the position sensor and controller, and calibrated as needed. For example, the pressure between the thermal transfer head and the printing medium is detected by a pressure sensor to ensure the uniformity of the printing effect.
[0062] Therefore, multi-dimensional interactions are performed on the thermal transfer area of the image and the moving system of the thermal transfer head. The position calibration sub-area is determined based on the multiple interactions of the thermal transfer area of the image and the moving system of the thermal transfer head. The thermal transfer area of the image and the moving system of the thermal transfer head are introduced, and multiple interactions are performed on the thermal transfer area of the image and the moving system of the thermal transfer head, thereby ensuring the precise line of the position calibration sub-area and realizing the control of the side during the thermal transfer process.
[0063] Specifically, the movement system of the thermal transfer head needs to interact with the thermal transfer area in multiple ways to ensure that the thermal transfer head can cover the entire thermal transfer area. At the same time, during the movement of the thermal transfer head, its position is monitored in real time and calibrated according to the boundary of the thermal transfer area. This process can be achieved through sensors (such as photoelectric sensors or encoders) to ensure that the thermal transfer head always stays within the thermal transfer area during movement to avoid deviation or wrong transfer.
[0064] Optionally, the thermal transfer area of the image to be transferred is identified by image processing technology. The area includes the pattern to be printed and its outer boundary; the moving range of the thermal transfer head on the X-axis, Y-axis and Z-axis is determined to ensure that it can cover the entire thermal transfer area;
[0065] During the movement of the thermal transfer head, its position is monitored in real time and calibrated according to the boundaries of the thermal transfer area. Use sensors (such as photoelectric sensors or encoders) to ensure that the thermal transfer head always stays within the thermal transfer area during movement. During the thermal transfer process, ensure side control and monitor the distance and pressure between the thermal transfer head and the target media through real-time feedback to ensure uniform pressure during the transfer process.
[0066] refer to Figure 4, in step S13, determining the heating sub-area according to the thermal transfer area of the image and the temperature control system of the thermal transfer head;
[0067] In the specific implementation process of the present invention, the specific steps may be:
[0068] S131: Acquire the thermal transfer area of the image;
[0069] S132: Determine the model information, service life, and temperature control area of the thermal transfer head based on the traversal of the thermal transfer head;
[0070] S133: determining a temperature control effect level of the thermal transfer head according to the model information, service life, and temperature control area of the thermal transfer head;
[0071] S134: determining a temperature control system of the thermal transfer head based on a temperature control effect level of the thermal transfer head and a moving speed of the thermal transfer head;
[0072] S135: Determine a heating sub-area according to the thermal transfer area of the image and the multi-dimensional interaction of the temperature control system of the thermal transfer head.
[0073] In an embodiment of the present application, the thermal transfer area of the image is obtained, and the thermal transfer area of the image is controlled, and at the same time, the model information, service life and temperature control area of the thermal transfer head are determined based on the traversal of the thermal transfer head; the temperature control effect level of the thermal transfer head is determined according to the model information, service life and temperature control area of the thermal transfer head, which is compatible with the overall consideration of the model information, service life and temperature control area of the thermal transfer head, realizes multi-dimensional control of the model information, service life and temperature control area of the thermal transfer head, and ensures the accuracy of the temperature control effect level of the thermal transfer head.
[0074] At this point, the thermal transfer printer goes through the initialization and detection process to traverse the thermal transfer head to obtain the following information:
[0075] Model information: The model of the thermal transfer head determines its basic performance and applicable scenarios. For example, different models of thermal transfer heads may have different resolutions, number of heating elements, and layout.
[0076] Service life: Calculate service life based on the first use date and current date of the device. The service life of the thermal transfer head is affected by factors such as the use environment and maintenance.
[0077] Temperature control area: The temperature control area refers to the effective working range of the thermal transfer head heating element, which is usually determined by the design of the thermal transfer head.
[0078] At the same time, based on the model information, service life and temperature control area of the thermal transfer head, the temperature control effect level is comprehensively evaluated. Model information influence: Different models of thermal transfer heads have differences in design. For example, the density and layout of the heating elements will affect the temperature control accuracy. Service life influence: The performance of the thermal transfer head will decrease with use time. For example, long-term use may cause aging of the heating element and affect the temperature control effect. Temperature control area influence: The design of the temperature control area determines the range in which the thermal transfer head can accurately control the temperature. Reasonable temperature control area design can improve printing quality and efficiency. By comprehensively considering the above factors, the temperature control effect is divided into different levels (such as A, B, C), where level A represents the best temperature control effect and level C represents poor temperature control effect.
[0079] Specifically, turn on the power of the thermal transfer printer and start the initialization program. Thermal transfer head traversal: The printer automatically detects the status of the thermal transfer head, including model information, service life and temperature control area. Model information: The thermal transfer head model read through the device firmware is "Epson SureColor F10080". Service life: The device record shows that the thermal transfer head was first used in January 2023, the current date is January 2025, and the service life is 2 years. Temperature control area: The temperature control area of the thermal transfer head covers the entire printing width (22 inches), the heating elements are evenly distributed, and high-resolution printing is supported. Epson SureColor F10080 is a high-performance thermal transfer head designed to support high-precision temperature control. Although it has been used for 2 years, the equipment is well maintained and the degree of aging of the heating elements is low. The temperature control area is reasonably designed and can evenly heat the entire printing width. According to a comprehensive evaluation, the temperature control effect of the thermal transfer head is graded B (good). Although it has been used for 2 years, the performance of the equipment can still meet the needs of high-precision printing.
[0080] At this time, the temperature control system of the thermal transfer head is determined based on the temperature control effect level of the thermal transfer head and the moving speed of the thermal transfer head; the heating sub-area is determined according to the thermal transfer area of the image and the multi-dimensional interaction of the temperature control system of the thermal transfer head.
[0081] Specifically, the temperature control effect level of the thermal transfer head is evaluated based on the model information, service life and temperature control area of the thermal transfer head. For example, if the temperature control effect level of the thermal transfer head is Class B (good), the temperature control parameters need to be appropriately adjusted; the moving speed of the thermal transfer head will affect the heating time and temperature distribution. Faster moving speeds require higher heating power to ensure sufficient heat transfer, while slower speeds require appropriate power reduction to avoid overheating; the temperature control system of the thermal transfer head is determined in combination with the temperature control effect level and moving speed. For example, for a thermal transfer head with a Class B temperature control effect, if the moving speed is 50mm / s, the system can increase the heating power by 5% and shorten the heating time to ensure printing quality. Optionally, the temperature control system of the thermal transfer head refers to a complete system for accurately controlling the temperature of the thermal transfer head, which includes a combination of hardware (such as heating elements, temperature sensors, temperature controllers) and software (such as temperature control algorithms, PLC control systems). The core goal of the temperature control system of the thermal transfer head is to ensure that the thermal transfer head can transfer the pattern on the ink or ribbon to the target medium at a precise temperature during the printing process, thereby achieving high-quality printing effects.
[0082] Furthermore, a multi-dimensional interactive analysis is performed in combination with the temperature control system of the thermal transfer head and the thermal transfer area of the image. For example, the movement path and heating strategy of the thermal transfer head are adjusted according to the shape and size of the thermal transfer area; the specific parameters of each heating sub-area, including the heating temperature, heating time and movement speed, are determined through interactive analysis. For example, for the heating sub-area of a complex pattern, the temperature can be appropriately increased and the movement speed can be reduced to ensure the clarity of the pattern. Optionally, the heating sub-area refers to a local heating area divided according to the thermal transfer area of the image and the temperature control system of the thermal transfer head during the thermal transfer process. It is the area where the thermal transfer head actually acts during the printing process, and is used to ensure that the thermal transfer head can efficiently and accurately transfer the pattern or text from the thermal transfer paper to the target medium.
[0083] Specifically, the temperature control effect level of the thermal transfer head is Class B, and the service life is 2 years; the moving speed of the thermal transfer head is 50mm / s; according to the temperature control effect level and moving speed, the system will increase the heating power by 5% and adjust the heating time to 20ms for each heating cycle; the thermal transfer area of the image is divided into 4 heating sub-areas, each of which corresponds to a different pattern part; the system dynamically adjusts the moving path and heating strategy of the thermal transfer head according to the pattern complexity and temperature control system parameters of each heating sub-area. For example, for the heating sub-area of the text part, the moving speed is appropriately reduced and the temperature is increased to ensure the clarity of the text or pattern.
[0084] refer to Figure 5 , S14: determining the thermal transfer logic of the thermal transfer head based on the heating sub-area, the calibration sub-area and the image;
[0085] In the specific implementation process of the present invention, the specific steps may be:
[0086] S141: Acquire a heating sub-area, a calibration sub-area, and a picture;
[0087] S142: Determine a first matching weight based on dynamic matching of the image and the heated sub-region;
[0088] S143: Determine a second matching weight based on dynamic matching of the image and the calibrated sub-region;
[0089] S144: The first matching weight, the second matching weight, the overall area of the image, and the temperature control system of the thermal transfer head are input into the logic learning model, and multiple thermal transfer events are output based on further training of the logic learning model, and the thermal transfer logic of the thermal transfer head is determined based on the classification of the multiple thermal transfer events.
[0090] In an embodiment of the present application, a heating sub-region, a calibration sub-region and a picture are obtained; a first matching weight is determined based on a dynamic matching of the picture and the heating sub-region; and a second matching weight is determined based on a dynamic matching of the picture and the calibration sub-region.
[0091] At this time, the heating sub-area is the local area where the thermal transfer head actually acts during the printing process, and is used to transfer heat to the thermal transfer paper or target medium. The division of the heating sub-area is based on the thermal transfer area of the image and the temperature control system of the thermal transfer head; the calibration sub-area is a reference area for calibrating the position of the thermal transfer head, usually located at the edge or specific position of the thermal transfer area, to ensure the movement accuracy of the thermal transfer head. The picture is the image or text content that needs to be printed, and its thermal transfer area has been identified through image processing technology, and the heating sub-area, calibration sub-area and picture are further controlled.
[0092] At the same time, the matching strategy is dynamically adjusted according to the characteristics of the thermal transfer area and the heating sub-area of the image. For example, for complex patterns or high-resolution images, the division of the heating sub-area may be finer; the first matching weight is a weight value determined according to the dynamic matching result, which is used to evaluate the matching degree between the heating sub-area and the thermal transfer area of the image. The higher the weight value, the higher the matching degree; optionally, the first matching weight is usually calculated by an algorithm, which reflects the similarity or matching degree between the heating sub-area and the thermal transfer area of the image. The higher the weight value, the higher the matching degree between the heating sub-area and the thermal transfer area of the image, and the more guaranteed the printing quality.
[0093] Optionally, during the thermal transfer process, the first matching weight can be used to adjust parameters such as the heating temperature, movement speed, and dwell time of the thermal transfer head to ensure uniformity and consistency of the printing effect. For example, for patterns that require high-precision printing, the first matching weight may be higher, thereby triggering a more sophisticated temperature control and movement strategy.
[0094] Optionally, in thermal transfer technology, the second matching weight refers to a weight value assigned based on the dynamic matching degree between the thermal transfer area and the calibration sub-area of the image. It is used to quantify the matching degree between the calibration sub-area and the thermal transfer area, thereby optimizing the printing logic and parameter settings of the thermal transfer head; the second matching weight is calculated by an algorithm and reflects the matching degree between the calibration sub-area and the thermal transfer area. The higher the weight value, the higher the matching degree between the calibration sub-area and the thermal transfer area, and the higher the printing accuracy.
[0095] The first matching weight focuses on the matching degree between the heating sub-area and the thermal transfer area, which is used to optimize the heating strategy of the thermal transfer head. It focuses more on the temperature control effect and heating efficiency of the thermal transfer head. The second matching weight focuses on the matching degree between the calibration sub-area and the thermal transfer area, which is used to optimize the moving path and position calibration of the thermal transfer head. It focuses more on the positioning accuracy of the thermal transfer head and the optimization of the printing path. By combining the first matching weight and the second matching weight, the thermal transfer system can achieve more accurate temperature control and position calibration, thereby improving printing quality and efficiency.
[0096] Furthermore, the first matching weight, the second matching weight, the overall area of the image, and the temperature control system of the thermal transfer head are input into the logic learning model, and multiple thermal transfer events are output based on further training of the logic learning model, and the thermal transfer logic of the thermal transfer head is determined based on the classification of the multiple thermal transfer events.
[0097] At this point, the logical learning model can be built based on machine learning algorithms (such as logistic regression) or deep learning algorithms (such as neural networks). The purpose of the model is to output the optimal thermal transfer strategy based on the input weights, area, and temperature control system.
[0098] For the input features of the logic learning model, the input features are the first matching weight, the second matching weight, the overall area of the image, and the temperature control system of the thermal transfer head. At this time, the first matching weight represents the matching degree between the heating sub-area and the thermal transfer area. The second matching weight represents the matching degree between the calibration sub-area and the thermal transfer area; the overall area of the image represents the complexity of the thermal transfer task; the temperature control system of the thermal transfer head includes the temperature control capability, heating speed, and cooling speed of the thermal transfer head.
[0099] Furthermore, the above features are input into the logic learning model, and the model is trained through historical data and experimental data. The goal of the model is to minimize the error in the thermal transfer process while maximizing the print quality; the logic learning model outputs multiple thermal transfer events based on the input features. Each event contains the following information:
[0100] Heating temperature: The temperature value adjusted according to the complexity of the image and the temperature control system.
[0101] Moving speed: The speed at which the thermal transfer head moves during printing.
[0102] Dwell time: The dwell time of the thermal transfer head in each heating sub-area.
[0103] At the same time, the generated thermal transfer events are classified according to their characteristics. For example, events that require high-precision printing are classified into one category, and events that require large-area printing are classified into another category. Based on the classified thermal transfer events, the thermal transfer logic of the thermal transfer head is determined, and the logic includes:
[0104] Heating strategy: Adjust heating temperature and time according to the complexity of the image and the temperature control system.
[0105] Moving path: Optimize the moving path of the thermal transfer head according to the calibration sub-area and the first and second matching weights.
[0106] Real-time feedback: Dynamically adjust the thermal transfer process through the real-time feedback mechanism of the temperature control system.
[0107] Specifically, the first matching weight is 0.9 (indicating that the heating sub-area and the thermal transfer area have a high matching degree). The second matching weight is 0.85 (indicating that the calibration sub-area and the thermal transfer area have a high matching degree). The overall area of the image is 100 square centimeters. The temperature control system of the thermal transfer head: the temperature range is 180°C-200°C, the heating speed is 5°C / s, and the cooling speed is 3°C / s.
[0108] Based on these inputs, the logical learning model outputs the following thermal transfer events:
[0109] Event 1: heating temperature 190°C, moving speed 10mm / s, dwell time 20ms.
[0110] Event 2: heating temperature 185°C, moving speed 12mm / s, dwell time 18ms.
[0111] Based on the classification of these events, the thermal transfer logic is determined as:
[0112] Use the parameters of Event 1 for high-precision areas such as text and thin lines.
[0113] Use the parameters of event 2 for large areas (such as background patches).
[0114] Through this dynamic adjustment based on the logical learning model, the thermal transfer head can complete the printing task efficiently and accurately while ensuring the printing quality.
[0115] refer to Figure 6 , S15: in the thermal transfer logic of the thermal transfer head, performing primary thermal transfer on the heating sub-region, and executing multi-level temperature compensation logic in the primary thermal transfer of the heating sub-region; determining a temperature distribution map of the heating sub-region based on the heating sub-region and the corresponding temperature data;
[0116] In the specific implementation process of the present invention, the specific steps may be:
[0117] S151: In the thermal transfer logic of the thermal transfer head, the form of each pattern in the heating sub-region is determined based on the traversal of the heating sub-region;
[0118] S152: Associating the shape of each pattern in the heating sub-region, the area of the heating sub-region, and the thermal transfer head;
[0119] S153: determining the primary thermal transfer of the heating sub-region according to the shape of each pattern in the heating sub-region, the area of the heating sub-region and the thermal transfer head, and performing the primary thermal transfer on the heating sub-region;
[0120] S154: monitoring the primary thermal transfer of the heating sub-area in real time, and executing a multi-level temperature compensation logic in the primary thermal transfer of the heating sub-area;
[0121] S155: triggering multi-stage heating of each pattern in the heating sub-area according to the multi-stage temperature compensation logic, at this time, matching corresponding step-by-step heating information of multiple different temperatures according to the shape of each pattern, the color tone of each pattern and the area of each pattern, and directionally heating the pattern according to the step-by-step heating information of multiple different temperatures;
[0122] S156: Monitor the heating process of the heating sub-area, mark the corresponding heating position and heating data, associate the heating sub-area, heating position and heating data, and determine the temperature distribution diagram of the heating sub-area according to the heating sub-area, heating position and heating data.
[0123] In an embodiment of the present application, in the thermal transfer logic of the thermal transfer head, the shape of each pattern in the heating sub-area is determined based on the traversal of the heating sub-area; the shape of each pattern in the heating sub-area, the area of the heating sub-area and the thermal transfer head are associated; the primary thermal transfer of the heating sub-area is determined according to the shape of each pattern in the heating sub-area, the area of the heating sub-area and the thermal transfer head, and the primary thermal transfer is performed on the heating sub-area.
[0124] At this time, the heating sub-areas are traversed, and the thermal transfer head visits the heating sub-areas one by one according to the preset path. Each heating sub-area is the local area where the thermal transfer head actually acts during the printing process. In each heating sub-area, the morphology of each pattern is identified through image processing technology (such as edge detection, contour extraction, deep learning algorithm, etc.), and the morphological features of each pattern are extracted, including shape (circular, rectangular, irregular shape), size, direction, color depth, etc. At the same time, computer vision algorithms (such as OpenCV) or deep learning models (such as convolutional neural networks, CNN) are used to identify the contours and features of the pattern.
[0125] Furthermore, the shapes of each pattern in the heating sub-region, the area of the heating sub-region and the thermal transfer are introduced to control the shapes of each pattern in the heating sub-region, the area of the heating sub-region and the thermal transfer.
[0126] At this time, the primary thermal transfer parameters of each heating sub-area are determined according to the shape of the pattern, the area of the heating sub-area and the characteristics of the thermal transfer head. The primary thermal transfer parameters of each heating sub-area include heating temperature, heating time and moving speed; at this time, heating temperature: select a suitable initial temperature according to the color depth and area of the pattern. Heating time: select a suitable heating time according to the complexity of the pattern and the moving speed of the thermal transfer head. Moving speed: select a suitable moving speed according to the shape and area of the pattern.
[0127] For the primary thermal transfer of the heating sub-area, the thermal transfer head preliminarily heats the heating sub-area according to the determined parameters to transfer the pattern from the thermal transfer paper to the target medium. During the primary thermal transfer process, the temperature change of the heating sub-area is monitored in real time by the temperature sensor to ensure the uniformity and consistency of the heating process.
[0128] Specifically, in the heating sub-area, identify the text (rectangle) and icon (circle). Record the shape, area and position of each pattern. Adjust the division of the heating sub-area according to the shape and area of the pattern. Consider the characteristics of the thermal transfer head and select appropriate primary thermal transfer parameters. The thermal transfer head preliminarily heats the heating sub-area according to the determined parameters, monitors the heating process, and ensures that each pattern can obtain the best printing effect.
[0129] Further, the primary thermal transfer of the heating sub-area is monitored in real time, and a multi-level temperature compensation logic is performed in the primary thermal transfer of the heating sub-area.
[0130] At this time, during the thermal transfer process, real-time monitoring of the primary thermal transfer of the heating sub-area and performing multi-level temperature compensation logic are key steps to ensure printing quality and efficiency. High-precision temperature sensors are installed in the thermal transfer head and the heating sub-area to monitor the temperature changes during the heating process in real time. The temperature sensor can be a thermocouple, thermistor or other high-precision temperature detection device. The actual temperature data of the heating sub-area is collected by the sensor and transmitted to the control system in real time. The control system compares and analyzes the preset temperature curve and the actual temperature data.
[0131] At the same time, multi-level temperature compensation logic refers to multi-stage temperature adjustment of the heating sub-area based on real-time monitoring data. This logic can be divided into multiple levels, each corresponding to a different temperature compensation strategy.
[0132] First level compensation: When temperature deviation is detected, the system first makes quick adjustments, such as increasing heating power or adjusting heating time.
[0133] Second level compensation: If the temperature still does not reach the expected level after the first level compensation, the system will further adjust the moving speed or dwell time of the heating sub-area.
[0134] Third level compensation: In extreme cases, the system may adjust the global temperature setting of the thermal transfer head or suspend heating to avoid overheating or damage.
[0135] Further,
[0136] Dynamically adjust heating parameters based on real-time monitoring data. For example, if the temperature of a certain pattern area is low, the system will increase the heating power of that area. For complex patterns or large areas, the system will perform local optimization based on the morphology and area of the pattern. For example, dark areas may require higher temperatures, while light areas require lower temperatures.
[0137] Assume that during the primary thermal transfer process, the actual temperature of a certain heating sub-area is 5°C lower than the preset temperature. First level compensation: The system increases the heating power of this area to make the temperature rise quickly. Second level compensation: If the temperature still does not reach the preset value, the system will appropriately extend the heating time of this area. Third level compensation: If the temperature deviation is large, the system may adjust the movement speed of the thermal transfer head to ensure that the area receives enough heat.
[0138] At the same time, multi-level heating of each pattern in the heating sub-area is triggered according to the multi-level temperature compensation logic. At this time, the corresponding step-by-step heating information of multiple different temperatures is matched according to the shape of each pattern, the tone of each pattern and the area of each pattern, and the pattern is directionally heated according to the step-by-step heating information of multiple different temperatures.
[0139] At this time, during the thermal transfer process, multi-level temperature compensation logic is used to ensure that each pattern can achieve the best printing effect in the heating sub-area. This process not only takes into account the shape, area and color tone of the pattern, but also dynamically adjusts the heating parameters according to real-time monitoring data to achieve precise directional heating. The actual temperature of the heating sub-area is monitored in real time by a temperature sensor and compared with the preset temperature. When the actual temperature deviates from the preset temperature, the system triggers the multi-level temperature compensation logic.
[0140] Furthermore, different heating strategies are assigned according to the shape (such as text, icons, large-area backgrounds) and complexity of the pattern; complex patterns (such as text, fine lines): require higher temperatures and slower movement speeds to ensure clarity; the heating temperature is adjusted according to the color depth of the pattern. Dark patterns usually require higher temperatures, while light patterns require lower temperatures; large-area patterns may require heating in stages to ensure even heat distribution.
[0141] Text pattern:
[0142] Shape: thin lines, small area.
[0143] Tone: Dark.
[0144] Heating parameters: temperature 190°C, time 20ms.
[0145] Icon pattern:
[0146] Morphology: Medium area, regular shape.
[0147] Tone: Medium.
[0148] Heating parameters: temperature 185°C, time 18ms.
[0149] Background pattern:
[0150] Morphology: Large area, irregular shape.
[0151] Color tone: Light color.
[0152] Heating parameters: temperature 180°C, time 15ms.
[0153] Therefore, the heating process of the heating sub-area is monitored, and the corresponding heating position and heating data are marked, the heating sub-area, heating position and heating data are associated, and the temperature distribution diagram of the heating sub-area is determined according to the heating sub-area, heating position and heating data.
[0154] At this time, the heating process of the heating sub-area is monitored, the specific position of each heating sub-area is marked, and the temperature, heating time, heating power and other data of each heating position are recorded. These data can be used for subsequent analysis and optimization.
[0155] Associate the heating sub-areas, heating positions, and heating data to fully analyze the heating process, and associate the temperature data of each heating sub-area with the corresponding heating position. For example, record the temperature changes of each heating point through a coordinate system; at the same time, organize the temperature data of the heating sub-areas to ensure the integrity and accuracy of the data, and use professional software (such as Origin) or programming tools (such as Canvas) to draw a temperature distribution map. The temperature distribution can be intuitively displayed in the form of a heat map or contour map; set a color map for the temperature distribution map to quickly identify high and low temperatures. For example, high temperature areas are represented by red and low temperature areas are represented by blue.
[0156] refer to Figure 7 , S16: determining a moving route of the thermal transfer head based on the temperature distribution map of the heating sub-area, the calibration sub-area and the thermal transfer head, determining a plurality of detection areas according to the moving route of the thermal transfer head and the thermal transfer area of the image, and matching a corresponding thermal transfer optimization event according to the printing effect level of each detection area and the area of each detection area;
[0157] In the specific implementation process of the present invention, the specific steps may be:
[0158] S161: Obtaining a temperature distribution diagram of the heating sub-area;
[0159] S162: In the thermal transfer printer, marking the temperature distribution map of the heating sub-area, the calibration sub-area, and the current position of the thermal transfer head;
[0160] S163: determining a working route of the thermal transfer head according to the interaction between the temperature distribution map of the heating sub-area, the calibration sub-area and the current position of the thermal transfer head, and determining a moving route of the thermal transfer head according to the working route of the thermal transfer head and the moving system of the thermal transfer head;
[0161] S164: determining a plurality of detection areas based on a moving route of the thermal transfer head and a thermal transfer area of the image;
[0162] S165: Detect each detection area and determine the printing effect level of each detection area;
[0163] S166: Matching corresponding thermal transfer optimization events based on the printing effect level of each detection area and the area of each detection area.
[0164] In the specific implementation process of the present invention, a temperature distribution map of the heating sub-area is obtained; in the thermal transfer printer, the temperature distribution map of the heating sub-area, the calibration sub-area and the current position of the thermal transfer head are marked; the working route of the thermal transfer head is determined based on the interaction of the temperature distribution map of the heating sub-area, the calibration sub-area and the current position of the thermal transfer head, and the moving route of the thermal transfer head is determined based on the working route of the thermal transfer head and the moving system of the thermal transfer head.
[0165] At this time, the temperature distribution map of the heating sub-area is obtained, and the temperature distribution map of the heating sub-area is controlled. At the same time, the temperature distribution map of the heating sub-area is introduced. The temperature distribution map of the heating sub-area can intuitively display the temperature uniformity of the heating sub-area and help identify overheating or low-temperature areas. The calibration sub-area is usually located at the edge or specific position of the heating sub-area; the position of the calibration sub-area is marked on the temperature distribution map to ensure that the thermal transfer head can be accurately aligned during the movement, and the current position of the thermal transfer head is obtained in real time and marked on the temperature distribution map.
[0166] Furthermore, the optimal working path is analyzed by combining the temperature distribution map, the calibrated sub-area and the current position of the thermal transfer head. The temperature abnormality area is avoided to ensure that the thermal transfer head works in an area with uniform temperature, thereby improving the printing quality. According to the working route and moving system of the thermal transfer head (such as the moving range of the X-axis, Y-axis and Z-axis), the moving path of the thermal transfer head is optimized, and the working route and moving system of the thermal transfer head are compatible, thus ensuring the accurate line of the moving route of the thermal transfer head.
[0167] Specifically, the sub-area and the current position of the thermal transfer head are marked on the temperature distribution map, the temperature distribution map is analyzed, the working route of the thermal transfer head is determined, the overheating area is avoided, and the moving path of the thermal transfer head is optimized according to the working route and the moving system to ensure that it can move accurately.
[0168] At this time, an infrared thermal imager is used to generate a temperature distribution map of the heating sub-area, showing that the temperature of the central area is 200°C and the temperature of the edge area is 180°C; on the temperature distribution map, the position of the sub-area is calibrated with green marks (located at the four corners of the heating sub-area); the current position of the thermal transfer head is marked with yellow (updated in real time); the temperature distribution map is analyzed to determine the working route of the thermal transfer head to avoid the overheating area; the moving path of the thermal transfer head is optimized according to the working route and movement system; the moving route is designed to start from the edge area and gradually move to the center area to ensure printing quality; the thermal transfer head prints according to the optimized moving route to ensure that each area can obtain the best printing effect.
[0169] Therefore, multiple detection areas are determined based on the moving route of the thermal transfer head and the thermal transfer area of the image; each detection area is detected and the printing effect level of each detection area is determined; and the corresponding thermal transfer optimization event is matched based on the printing effect level of each detection area and the area of each detection area.
[0170] At this time, the entire printing area is divided into multiple detection areas according to the movement route of the thermal transfer head and the thermal transfer area of the image. These areas can be divided based on the complexity of the pattern, the depth of color or the size of the area; on the movement path of the thermal transfer head, the starting point and the end point of each detection area are marked, which helps to monitor the printing effect of each area in real time during the printing process. Optionally, assuming that the image contains text, pattern and background, the detection area can be divided into text area, pattern area and background area.
[0171] Furthermore, each detection area is tested in real time. The test contents include color uniformity, pattern clarity, stratification, etc. During the printing process, the printing effect of each detection area is monitored in real time. This can be done through the built-in detection system of the thermal transfer printer. At the same time, the printing effect of each detection area is rated according to the test results. The printing effect level can be divided into A (excellent), B (good), C (qualified), D (unqualified), etc. Example: The printing effect level of the text area is A, the pattern area is B, and the background area is C.
[0172] According to the printing effect level and area of the detection area, the corresponding thermal transfer optimization event is matched. The optimization event can include temperature adjustment, movement speed adjustment, heating time adjustment, etc. Example:
[0173] For the area with printing effect level A, keep the current parameters unchanged. For the area with printing effect level B, increase the heating time appropriately. For the area with printing effect level C, adjust the temperature and moving speed. Furthermore, according to the matching optimization event, dynamically adjust the parameters of the thermal transfer head. This can be done automatically by the control system of the thermal transfer printer. During the thermal transfer process, the optimized printing effect is fed back in real time to ensure the improvement of printing quality.
[0174] Specifically, the printing area is divided into text area, pattern area and background area. Each detection area is tested, the printing effect level is evaluated, and the corresponding optimization events are matched according to the printing effect level and area, and the parameters of the thermal transfer head are dynamically adjusted to ensure the improvement of printing quality.
