Abstract
Description
Technical Field
[0001] This application relates to the field of printing technology, and in particular to a printing calibration method, apparatus, electronic device, and computer storage medium. Background Technology
[0002] In practical applications of printing equipment, especially in cable labeling in industries such as power, communications, and automation control, it is often necessary to print labels on conduits. Conduits, as a commonly used cable protection material, have characteristics such as elasticity and shrinkability. While these characteristics give conduits flexibility and adaptability in the installation and wiring process, they also bring challenges to the printing process of printing equipment.
[0003] Specifically, when a printer is printing, the tubing often needs to be stretched or bent according to the printer's guide path. Because the tubing itself has a certain degree of elasticity, if the tubing cannot maintain a stable state during the printing process, this stretching or bending may cause the actual length of the tubing during printing to deviate from the preset value.

[0064] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0065] The terms "first," "second," "third," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.
[0066] Please refer to the following. Figure 1 The illustration shows a schematic diagram of the structure of a printing device provided in an embodiment of this application. Figure 1 As shown, the printing device 100 may include, but is not limited to, a controller 110, a stepper motor 120, and a printhead 130. Wherein:
[0067] The aforementioned printing equipment 100 can be a wire marking machine, which can be used, but is not limited to, for printing characters on materials such as PVC tubing, heat shrink tubing, and self-adhesive labels. Examples include, but are not limited to, stand-alone wire marking machines, online wire marking machines, and Bluetooth wire marking machines. Its working principle is mainly based on thermal printing technology, where heating the thermal paper produces a chemical reaction, thereby displaying text or images. The wire marking machine uses thermal paper as the printing medium; its thermal coating is heat-sensitive and changes color when exposed to heat. When the print head of the wire marking machine is heated, the thermal paper changes color, thus forming the desired text or image.
[0068] The controller 110 is the brain of the printing device 100. It is mainly responsible for receiving and processing printing instructions from a computer or other device (such as a terminal), converting them into control signals suitable for the printer, and controlling the print head 130, stepper motor 120 and other components to work together to complete the printing task according to the control signals.
[0069] Specifically, when the controller 110 receives the print calibration command, it can first obtain the target print calibration coefficient corresponding to the tube to be printed. The target print calibration coefficient is the stretching and compression ratio between the actual length of the tube to be printed after printing and the theoretical length before printing. Then, it determines the target stepping cycle corresponding to the printing device 100 according to the target print calibration coefficient. Finally, it controls the print head 130 of the printing device 100 to print according to the target printping cycle, and controls the stepper motor 120 of the printing device 100 to drive the tube to be printed to move forward according to the target stepping cycle.
[0070] The stepper motor 120 is mainly responsible for driving the precise movement of components such as the print head 130 and the mechanical transmission mechanism. It is typically composed of components such as a stator, rotor, and driver, and has a simple structure that is easy to maintain. In this embodiment, the rotation of the stepper motor 120, after passing through the mechanical transmission mechanism, can drive the rubber roller to rotate, which in turn drives the tubing to move.
[0071] The printhead 130 is one of the core components of the printing device 100. It is responsible for transferring printing materials such as ink or toner onto the printing tube to form text, images, or charts. Depending on the printing technology, the structure and working principle of the printhead 130 may vary, and this embodiment does not limit this.
[0072] Understandably, the aforementioned printing device 110 may also include, but is not limited to, one or more buttons, a display screen, indicator lights, etc.
[0073] It is understood that the printing calibration method provided in this application embodiment can be executed by the controller 110 of the printing device 100, or by the controller 110 of the printing device 100 and a terminal that is communicatively connected to the printing device 100. This application embodiment does not limit this.
[0074] Next, combine Figure 1 This application describes a printing calibration method provided by an exemplary embodiment. Please refer to [reference needed] for details. Figure 2 The example illustrates a flowchart of a printing calibration method provided in an embodiment of this application. Figure 2 As shown, this print calibration method includes the following steps:
[0075] S201, obtain the target printing calibration coefficient corresponding to the tube to be printed. The target printing calibration coefficient is the stretching and compression ratio between the actual length of the tube after printing and the theoretical length before printing.
[0076] Optionally, when a user finds that the actual printed length of the tube to be printed deviates, such as the printed tube being compressed or stretched compared to before printing, the user can, based on experience, input the target printing calibration coefficient corresponding to the tube to be printed into the printing device through the display screen or buttons of the printing device.
[0077] Optionally, such as Figure 3 As shown, the process of obtaining the target printing calibration coefficient corresponding to the tube to be printed in S201 above may include, but is not limited to, the following steps:
[0078] S301 controls the printing device to print a section of the theoretical length of the tube to be printed based on the target printing cycle and the initial stepping cycle, thus obtaining a section of the test tube.
[0079] Specifically, in line-number printing scenarios, the printed image content is printed pixel by pixel. After printing one line of image content, a stepper motor rotates, moving the tube forward one pixel's distance, and then the next line of image content is printed. All lines of image content are printed to form a complete image. The time required to print one line of image content is the printing cycle, and the time required for the stepper motor to move the tube forward one pixel's distance is the stepping cycle. Normally, the printing cycle and the stepping cycle are equal. That is, printing is initiated once per printing cycle, and the stepper motor moves the tube one pixel's distance per stepping cycle. The printing cycle and the stepping cycle are synchronized (starting and ending simultaneously) to complete the printing of one pixel. In this case, the ratio of the printing cycle to the stepping cycle is 1.0. For example, if printing a 10mm long tube takes 1 second, and the printing cycle is executed 100 times, the printing cycle = 1 / 100 = 0.01s. Similarly, the corresponding stepping cycle also needs to be executed 100 times, with a stepping cycle = 1 / 100 = 0.01s. In other words, during the testing phase, the initial stepping cycle used to print a section of the theoretically required length of the tube to be printed is equal to the target printing cycle. The theoretical length refers to the length of the tube to be printed before printing during the testing phase; it can also be understood as the target length of the tube to be printed during the testing phase. During the testing phase, the print head of the printing device can be controlled to print according to the target printing cycle, and the stepper motor of the printing device can be controlled to move the tube to be printed forward according to an initial stepping cycle equal to the target printing cycle, until a section of the theoretically required length of the tube is printed, resulting in a completed test tube.
[0080] S302, obtain the actual length of the test conduit.
[0081] Optionally, the printing equipment may be equipped with a ranging component (e.g., but not limited to, a laser rangefinder). After printing a section of the theoretical length of the tube to be printed to obtain a section of the test tube, the printing equipment may, but is not limited to, use its ranging component to scan the section of the test tube to obtain the actual length of the test tube after printing.
[0082] Optionally, the printing device may also be equipped with an image acquisition component (e.g., but not limited to, a camera). After printing a section of the theoretical length of the test tube to be printed, the printing device may, but is not limited to, use its image acquisition component to acquire an image of the test tube and use image detection technology to detect the length of the test tube in the acquired image to obtain the actual length of the test tube after printing.
[0083] Optionally, after the printing device prints a section of test tubing of theoretical length, the user can use, but is not limited to, measuring tools (such as rulers, vernier calipers, etc.) to physically measure the printed test tubing to obtain its actual length, and input the actual length into the printing device through the display screen or buttons of the printing device or a terminal connected to the printing device.
[0084] S303 calculates the target printing calibration coefficient corresponding to the tube to be printed based on the actual length and theoretical length.
[0085] Specifically, after obtaining the actual length of the tube to be printed after printing and its theoretical length before printing, the stretching-compression ratio between the actual and theoretical lengths can be directly calculated to obtain the target printing calibration coefficient. This target printing calibration coefficient can be used to adjust the stepping cycle of the printing equipment to more accurately print the tube of the target length.
[0086] Understandably, the aforementioned target printing calibration coefficient can be the ratio between the actual length and the theoretical length, or it can be an adjustment factor calculated based on the difference between the actual length and the theoretical length. This application does not limit this.
[0087] In some possible embodiments, the process of obtaining the target printing calibration coefficient corresponding to the duct to be printed in S201 may include, but is not limited to, obtaining the target material type corresponding to the duct to be printed. For example, but not limited to, obtaining the model, specifications, and other information of the duct to be printed, and then querying the corresponding target material type through the above information; or directly receiving the target material type input by the user through the display screen or buttons of the printing device or a terminal connected to the printing device; or, but not limited to, using an image acquisition component to acquire an image of the duct to be printed, and using image detection technology to detect the material type of the duct to be printed in the acquired image to obtain the target material type corresponding to the duct to be printed. The above target material type refers to the type of material used in the duct to be printed. Then, according to the above target material type, a query is performed in a preset coefficient mapping relationship to obtain the corresponding target printing calibration coefficient. The above preset coefficient mapping relationship is used to characterize the correspondence between the material type of the duct and the printing calibration coefficient. The above preset coefficient mapping relationship may be, but is not limited to, a database or table used to store and query the correspondence between the duct material type and the printing calibration coefficient. With the development of new materials and printing technology, the above preset coefficient mapping relationship can be updated regularly to ensure its accuracy and applicability. The aforementioned printing calibration coefficients are predetermined coefficients used to correct errors caused by differences in material type and liner movement during the printing process.
[0088] In this embodiment, the target printing calibration coefficient of the duct to be printed can be obtained quickly and accurately by querying the target material type of the duct through a preset coefficient mapping relationship, thereby improving printing efficiency and accuracy.
[0089] Understandably, the target material types corresponding to the above-mentioned ducts to be printed are different, and their corresponding target printing calibration coefficients are different. This allows for differentiated printing calibration based on the target material type of the duct to be printed, improving the targeting and accuracy of printing calibration, and thus further enhancing the printing effect.
[0090] In some possible embodiments, the process of obtaining the target printing calibration coefficient corresponding to the duct to be printed in S201 may include, but is not limited to, obtaining the target printing calibration coefficient corresponding to the duct when a change in the material type of the duct to be printed is detected. That is, the printing device may be equipped with a sensor to detect the material type of the duct to be printed. When a change in the material type of the duct to be printed is detected, i.e., when a new material type of duct needs to be printed, the acquisition of the target printing calibration coefficient corresponding to the duct can be automatically triggered. This allows the printing device to automatically adapt to the printing requirements of different material types without manual parameter adjustment, reducing printing errors caused by material differences and improving the flexibility, ease of use, and printing accuracy of the printing device.
[0091] Please continue to refer to the following. Figure 2 ,like Figure 2 As shown, after obtaining the target printing calibration coefficient corresponding to the tube to be printed in S201 above, the printing calibration method may also include, but is not limited to, the following:
[0092] S202, determine the target stepping cycle corresponding to the printing device based on the target printing calibration coefficient.
[0093] Specifically, after obtaining the target print calibration coefficient, the target stepping cycle can be calculated based on the obtained target print calibration coefficient. For example, but not limited to, adjusting the reference stepping cycle of the printing device based on the target print calibration coefficient to obtain the target stepping cycle. The aforementioned reference stepping cycle is the rotation cycle of the stepper motor of the printing device under default settings, for example, but not limited to, the initial stepping cycle used when testing the target print calibration coefficient.
[0094] In some possible embodiments, the target printing calibration coefficient can be, but is not limited to, the stretching-compression ratio between the actual length of the duct to be printed after printing under the target printing cycle and the initial stepping cycle and the theoretical length before printing. The process of determining the target stepping cycle corresponding to the printing device based on the target printing calibration coefficient in S202 can include, but is not limited to, adjusting the initial stepping cycle according to the target printing calibration coefficient to obtain the target stepping cycle corresponding to the printing device.
[0095] Optionally, the process of adjusting the initial stepping cycle according to the target printing calibration coefficient to obtain the target stepping cycle corresponding to the printing device may include, but is not limited to:
[0096] When the target printing calibration coefficient is less than 1, such as Figure 4AAs shown, the actual length of the printed tube is less than the theoretical length before printing, indicating compression. Therefore, the initial stepping cycle needs to be reduced to a target multiple (i.e., the target printing calibration coefficient) to obtain the target stepping cycle for the printing device. This allows a target printing cycle to contain more stepping cycles, thus lengthening the printed content to compensate for the compression. For example, ideally, printing a 100mm long tube requires a target printing cycle T1 = initial stepping cycle T2 = 1000 cycles, with one initial stepping cycle corresponding to a tube movement of 0.1mm. During the testing phase, if the theoretical length is 100mm and the actual length is 95mm, a compression phenomenon occurs in the printed length. In one initial step cycle, the actual distance the stepper motor moves the tube is less than the distance of one line of pixels. That is, without calibration, after 1000 initial step cycles, the actual printed tube length is 95mm, meaning the tube only moves 0.095mm in one initial step cycle. If the target print cycle to step cycle ratio remains 1.0 (i.e., the target print cycle and target step cycle are equal), the actual printed length after one target print cycle is less than one... Based on the row pixel distance, the target print calibration coefficient P1 = 0.95 can be determined. After performing the above segment length calibration according to the target print calibration coefficient, a 100mm long tube is printed. The target print cycle is executed 1000 times. The target step cycle is executed 1000 / 0.95 times because it is reduced to 0.95 times of the initial print cycle. The length of the tube moved by each target step cycle is 0.095mm. Therefore, the actual total printed length of the tube in the 1000 / 0.95 target step cycle is L = (1000 / 0.95) × 0.095 = 100mm, thus achieving the print segment length calibration.
[0097] When the target printing calibration coefficient is greater than 1, such as Figure 4BAs shown, the actual length of the printed tube is greater than the theoretical length before printing, indicating a stretching phenomenon. Therefore, the initial step cycle needs to be increased to a target multiple (i.e., the target print calibration coefficient) to obtain the target step cycle corresponding to the printing device. This allows for fewer step cycles within a single target print cycle, compressing the printed content to compensate for the stretching. For example, if the theoretical length is 100mm and the actual length is 105mm, the stretching phenomenon occurs. In one initial step cycle, the stepper motor moves the tube a distance greater than one line of pixels. That is, without calibration, if the stepper motor steps for 1000 initial step cycles, the actual printed tube length is 105mm, but the tube only moves 0.105mm in one initial step cycle. If the target print cycle to step cycle ratio remains 1.0 (i.e., the target print cycle and target step cycle are equal), the actual printed length after one target print cycle is greater than one line of pixels. Therefore, the target printing calibration coefficient P1 = 105 / 100 = 1.05. After performing the above segment length calibration according to the target printing calibration coefficient, a 100mm long tube is printed. The target printing cycle is executed 1000 times. The target step cycle is increased to 1.05 times the initial printing cycle and is executed 1000 / 1.05 times. The length of the tube moved by each target step cycle is 0.105mm. Therefore, the actual total printed length of the tube in the 1000 / 1.05 target step cycle is L = (1000 / 1.05) × 0.105 = 100mm, thus achieving the printing segment length calibration.
[0098] Optionally, such as Figure 5A As shown, under ideal printing conditions, the ratio between the target printing cycle T1 and the initial stepping cycle T2 used by the printing device is 1. In this case, precise segment length printing can be achieved without calibration. However, when the actual printed length is compressed, printing calibration is performed, as shown... Figure 5B As shown, due to the reduced step cycle, the ratio between the target printing cycle T1 and the adjusted target step cycle T3 will be greater than 1. However, when stretching occurs in the actual printed length, after printing calibration, as... Figure 5C As shown, due to the increased step cycle, the ratio between the target printing cycle T1 and the adjusted target step cycle T3 will be less than 1. The target printing cycle includes heating time t1 and cooling time t2. Different ratios between heating time t1 and cooling time t2 result in different print densities. To maintain consistent print density on the tube before and after calibration, the ratio between the heating and cooling times of the print head will remain unchanged before and after the initial step cycle adjustment. This ensures both the actual printing length of the calibrated tube and the printing quality on the tube.
[0099] In some possible embodiments, the process of determining the target stepping cycle corresponding to the printing device based on the printing calibration coefficient in S202 above may include, but is not limited to, calculating the product between the target printing cycle and the target printing calibration coefficient to obtain the target stepping cycle corresponding to the printing device. For example, when the target printing calibration coefficient under the target printing cycle T1 is P1, the calibrated target stepping cycle T3 = T1 × P1 can be calculated.
[0100] S203 controls the print head of the printing equipment to print according to the target printing cycle, and controls the stepper motor of the printing equipment to drive the tube to be printed to move forward according to the target stepping cycle.
[0101] Specifically, after determining the target stepping cycle, the printer's controller will control the print head's printing operation according to the target printing cycle, and simultaneously control the stepper motor's rotation according to the target stepping cycle, thereby driving the printable line tube forward at an appropriate speed and step size. The control of the print head and stepper motor is performed synchronously to ensure printing accuracy and continuity.
[0102] In this embodiment, the stepping cycle of the stepper motor that drives the tube to be printed forward is adjusted by using the stretching and compression ratio between the actual length of the tube after printing and the theoretical length before printing, i.e., the target printing calibration coefficient corresponding to the tube. This adjusts the compression or stretching amount of the tube during printing, compensating for the compression or stretching during the printing process. This solves the problem of the actual printed tube length being too long or too short in tube printing scenarios, achieving segment length calibration, improving the accuracy and reliability of the printed segment length, and enabling the printing equipment to be applicable to more types of tube printing needs.
[0103] Please refer to the following. Figure 6 The illustration shows a schematic diagram of the implementation process of a printing calibration method provided in an embodiment of this application. Figure 6 As shown, when the user manually triggers or the printing device automatically triggers segment length calibration (print calibration), after the printing device starts segment length calibration (print calibration), it can directly query the target printing calibration coefficient of the tube to be printed based on the target material type corresponding to the obtained tube through a preset coefficient mapping relationship. Alternatively, the printing device can first print a theoretical length of the tube to be printed, then measure the actual length of the tube after printing, and calculate the target printing calibration coefficient of the tube to be printed based on the actual length and the theoretical length. Then, a target stepping cycle can be determined based on the target printing calibration coefficient, but not limited to, following a process similar to S202.
