Description

Technical Field

[0001] Several embodiments of this specification relate to the field of printing technology, specifically to a method, apparatus, and printing device for generating a printing air pressure control function. Background Technology

[0002] In the printing process, print quality primarily depends on the consistency of line thickness and linewidth. Assuming a stable printing height, air pressure control directly determines variations in line thickness and linewidth. Simultaneously, the increased accumulation time of material in the feed tube leads to dynamic changes in material properties, particularly viscosity. This, in turn, causes drift in print output parameters, resulting in line thickness and linewidth deviations from standard requirements, deterioration of product uniformity, and even quality issues such as decreased yield, abnormal morphology, and material failure.

[0003] Furthermore, the dynamic changes in material properties due to the increasing cumulative time the material spends in the feed tube exhibit non-linearity. Therefore, the air pressure values ​​that ensure consistent line thickness and line width at each moment throughout a long production cycle, as well as the corresponding continuous printing duration at each moment, also show significant non-linear characteristics. This necessitates acquiring a large amount of fitting data during the construction of the air pressure control function to ensure its control effect.

[0004] Therefore, there is an urgent need for a solution that can efficiently generate printing air pressure control functions. Summary of the Invention

[0005] This specification provides a method, apparatus, and printing device for generating a printing air pressure control function.

[0006] The technical solution is as follows: Firstly, embodiments of this specification provide a method for generating a printing air pressure control function, including: The first linear control function of printing air pressure, which is only related to the continuous printing time, is obtained to guide the printing of target line width and target line thickness in the initial time stage and can be used to print the target printing material with target characteristics. When the current time phase ends, obtain the phase line width and phase line thickness printed under the guidance of the first printing pressure linear control function corresponding to the current time phase, and record the phase pressure value at this time. The printing air pressure is adjusted based on the preset compensation air pressure value to obtain the compensation line width and compensation line thickness after the air pressure is adjusted, and the compensation air pressure value is recorded. Based on the compensated air pressure value, compensated line width, compensated line thickness, stage air pressure value, stage line width, and stage line thickness, the second printing air pressure linear control function corresponding to the next time stage is obtained, which is only related to the product of the line width and the line thickness. Based on the second printing pressure linear control function, target line width, and target line thickness corresponding to the next time stage, the parameters of the first printing pressure linear control function corresponding to the previous time stage are updated to generate a first printing pressure linear control function that is only related to the continuous printing duration and can guide the printing of the target line width and target line thickness in the next time stage. Repeat the above steps to generate the first linear control function for the printing pressure corresponding to each time stage.

[0007] As a preferred embodiment, the first linear control function of printing air pressure, which is only related to the continuous printing time and corresponds to the target characteristic printing material and can guide the printing of target linewidth and target line thickness in the initial time stage, includes: For printing materials with target characteristics, the printing air pressure is adjusted at preset time intervals during the initial time phase to ensure that the actual line width and actual line thickness obtained after each printing air pressure adjustment reach the target line width and target line thickness. The printing air pressure and continuous printing time corresponding to each time the target line width and target line thickness are reached are recorded. Based on the printing pressure and continuous printing time corresponding to each time the target line width and target line thickness are reached, a first linear control function of printing pressure, which is only related to the continuous printing time, is obtained to guide the printing of the target line width and target line thickness in the initial time stage.

[0008] As a preferred option, the duration of each time phase is equal, and the duration of each time phase is set as follows: Obtain printing materials with different properties; Each printing material is used for printing operations, and each printing operation includes adjusting the printing air pressure at preset time intervals to ensure that the actual line width and actual line thickness reach the target line width and target line thickness after each printing air pressure adjustment. The printing air pressure and continuous printing time at each time the target line width and target line thickness are reached are recorded, thereby obtaining the printing dataset corresponding to each printing material. Based on the printing dataset corresponding to each printing material, the time-pressure fitting curve corresponding to each printing material is obtained; Based on the time-pressure fitting curve corresponding to each printing material, the optimal linear time length corresponding to each printing material is obtained. The duration of each time stage is set based on the preferred linear time length corresponding to each printing material.

[0009] As a preferred embodiment, the step of obtaining the second printing pressure linear control function, which is only related to the product of the line width and line thickness, based on the compensated air pressure value, compensated line width, compensated line thickness, stage air pressure value, stage line width, and stage line thickness, for the next time stage includes: Based on the compensated air pressure value, compensation line width, compensation line thickness, stage air pressure value, stage line width, and stage line thickness, the second proportional coefficient term in the second printing air pressure linear control function is obtained; Based on the obtained second proportional coefficient term, stage air pressure value, stage line width, and stage line thickness, the second intercept term in the second printing air pressure linear control function is obtained. Based on the obtained second proportional coefficient term and second intercept term, the second linear control function of printing air pressure corresponding to the next time stage is obtained, which is only related to the product of line width and line thickness.

[0010] As a preferred option, the second linear control function for printing air pressure is Pa2=k2*(W2*H2)+b2; Wherein, Pa2 represents the second printing air pressure parameter, k2 represents the second proportional coefficient parameter, b2 represents the second intercept parameter, W2 represents the second line width parameter, and H2 represents the second line thickness parameter. k2=(P1-P2) / (W1*H1-W2*H2), b2=P1- k2*(W1*H1); Wherein, P1 represents the stage pressure value, P2 represents the compensated pressure value, W1 represents the stage line width, W2 represents the compensated line width, H1 represents the stage line thickness, and H2 represents the compensated line thickness.

[0011] As a preferred embodiment, the step of updating the parameters of the first printing pressure linear control function corresponding to the previous time stage based on the second printing pressure linear control function, target line width, and target line thickness corresponding to the next time stage, to generate a first printing pressure linear control function that can guide the printing of the target line width and target line thickness in the next time stage and is only related to the continuous printing duration, includes: Substitute the target line width and target line thickness into the second printing pressure linear control function corresponding to the next time stage to obtain the target pressure; Based on the target air pressure, the stage air pressure value, and the duration of the time stage, the air pressure compensation amount is obtained. Based on the target air pressure and air pressure compensation amount, the first proportional coefficient term and the first intercept term in the first printing air pressure linear control function corresponding to the previous time stage are updated to generate a first printing air pressure linear control function that can guide the printing of the target line width and target line thickness in the next time stage and is only related to the continuous printing time.

[0012] As a preferred embodiment, the step of updating the parameters of the first proportional coefficient term and the first intercept term in the first printing pressure linear control function corresponding to the previous time stage based on the target air pressure and the air pressure compensation amount includes: The parameters of the first intercept term in the linear control function of the first printing pressure corresponding to the previous time stage are updated based on the target air pressure. The parameters of the first proportional coefficient term in the first linear control function of the first printing air pressure corresponding to the previous time stage are updated based on the air pressure compensation amount.

[0013] As a preferred option, the first linear control function for printing air pressure is Pa1=k1*t1+b1; Where Pa1 represents the first printing air pressure parameter, k1 represents the first proportional coefficient, b1 represents the first intercept, and t1 represents the continuous printing duration. The parameter update of the first intercept term in the linear control function of the first printing pressure corresponding to the previous time stage based on the target air pressure is to replace the parameter value corresponding to the first intercept term with the target air pressure. The parameter update of the first proportional coefficient term in the first printing air pressure linear control function corresponding to the previous time stage based on the air pressure compensation amount is that the air pressure compensation amount is used as the increment of the parameter value of the first proportional coefficient term in the first printing air pressure linear control function corresponding to the previous time stage, so as to update the parameter of the first proportional coefficient term in the first printing air pressure linear control function corresponding to the previous time stage. The formula for calculating the air pressure compensation is (target air pressure - stage air pressure value) / duration of the time stage.

[0014] Secondly, embodiments of this specification provide a printing air pressure control function generation device, comprising: The first function acquisition module acquires the first linear control function of printing air pressure, which is only related to the continuous printing time and corresponds to the target characteristic printing material, and can guide the printing of the target line width and target line thickness in the initial time stage. The first printing parameter acquisition module, when reaching the end of the time stage, acquires the stage line width and stage line thickness printed under the guidance of the first printing air pressure linear control function corresponding to the time stage that has reached the end of the time stage, and records the stage air pressure value at this time. The second printing parameter acquisition module adjusts the printing air pressure based on the preset compensation air pressure value to obtain the compensation line width and compensation line thickness printed after the air pressure adjustment, and records the compensation air pressure value. The second function acquisition module obtains the second printing pressure linear control function corresponding to the next time stage based on the compensated air pressure value, compensated line width, compensated line thickness, stage air pressure value, stage line width, and stage line thickness. This function is only related to the product of the line width and line thickness. The function update module updates the parameters of the first printing pressure linear control function corresponding to the previous time stage based on the second printing pressure linear control function, target line width, and target line thickness corresponding to the next time stage. This generates a first printing pressure linear control function that is only related to the continuous printing duration and can guide the printing of the target line width and target line thickness in the next time stage.

[0015] Thirdly, embodiments of this specification provide a printing apparatus, including: The first linear control function for printing air pressure corresponding to each time stage is generated by the method described in the first aspect of the above embodiments, so as to guide the control of printing air pressure in each time stage.

[0016] Fourthly, embodiments of this specification provide an electronic device, including a processor and a memory; the processor is connected to the memory; the memory is used to store executable program code; the processor reads the executable program code stored in the memory to run a program corresponding to the executable program code, so as to perform the steps described in the first aspect of the above embodiments.

[0017] Fifthly, embodiments of this specification provide a computer storage medium storing a plurality of instructions adapted for loading by a processor and executing the steps described in the first aspect of the above embodiments.

[0018] The beneficial effects of the technical solutions provided in some embodiments of this specification include at least the following: First, a first linear control function for printing air pressure is obtained to guide the initial printing time stage and determine the target line width and thickness. At the end of each time stage, based on the stage line width, stage line thickness, and stage air pressure values ​​obtained under the guidance of the first linear control function, and combined with the compensated line width, compensated line thickness, and compensated air pressure values ​​after adjustment using a preset compensation air pressure value, a second linear control function for printing air pressure, which is only related to the product of line width and line thickness, is derived. Finally, based on this second linear control function and the target line width and target line thickness, the parameters of the first linear control function are updated to generate a new first linear control function for printing air pressure, thus forming a dual closed-loop control mechanism. That is, only the fitting data for constructing the first linear control function for the initial time stage needs to be obtained in the early stages. While ensuring control accuracy, this significantly reduces the complexity of constructing the air pressure control function and the data acquisition cost in the early stages, reduces system startup and debugging time, and also improves the dynamic response capability and adaptability of air pressure control throughout the printing process, providing strong technical support for efficient and high-precision printing production.

[0026] Reference Figure 1 As shown, Figure 1 A flowchart illustrating a method for generating a printing air pressure control function, provided in an embodiment of this specification, may include at least: Step 102: Obtain the first linear control function of printing air pressure corresponding to the target characteristic printing material, which can guide the printing of target line width and target line thickness in the initial time stage and is only related to the continuous printing time. Step 104: When the current time stage ends, obtain the stage line width and stage line thickness printed under the guidance of the first printing pressure linear control function corresponding to the current time stage, and record the stage pressure value at this time. Step 106: Adjust the printing air pressure based on the preset compensation air pressure value to obtain the compensation line width and compensation line thickness after the air pressure adjustment, and record the compensation air pressure value. Step 108: Based on the compensated air pressure value, compensated line width, compensated line thickness, stage air pressure value, stage line width, and stage line thickness, obtain the second printing air pressure linear control function corresponding to the next time stage, which is only related to the product of the line width and the line thickness. Step 110: Based on the second printing pressure linear control function, target line width, and target line thickness corresponding to the next time stage, update the parameters of the first printing pressure linear control function corresponding to the previous time stage to generate a first printing pressure linear control function that can guide the printing of the target line width and target line thickness in the next time stage and is only related to the continuous printing duration. Step 112: Repeat the above steps to generate the first linear control function for printing air pressure corresponding to each time stage.

[0027] First, a first linear control function for printing pressure is obtained to guide the initial printing time stage, determining the target line width and thickness. At the end of each time stage, based on the stage line width, thickness, and pressure values ​​obtained under the guidance of this first linear control function, and combined with the compensated line width, thickness, and pressure values ​​after adjustment using a preset compensation pressure value, a second linear control function for printing pressure is derived, which is only related to the product of the line width and thickness. Finally, based on this second linear control function and the target line width and thickness, the parameters of the first linear control function are updated to generate a new first linear control function for printing pressure, thus forming a dual closed-loop control mechanism. This means that only the fitting data for constructing the first linear control function for the initial time stage needs to be obtained initially. While ensuring control accuracy, this significantly reduces the complexity of constructing the initial pressure control function.

[0028] It should be noted that the above solution is applicable in scenarios where only the line width and thickness need to remain constant during the printing process, without requiring any personalized adjustments. Furthermore, the entire printing process only changes the printing air pressure parameters, without altering other printing parameters. The properties of the printing material can include, but are not limited to, viscosity, density, surface tension, etc.

[0029] Furthermore, it should be noted that the implementation of the above scheme is based on the premise that if the line width and line thickness remain unchanged during the printing process, the printing air pressure and continuous printing time will still show a relatively stable linear relationship in the short term from the start to the end of printing (that is, although the air pressure data and the corresponding continuous printing time data at each moment can maintain the line thickness and line width at each moment in a long production cycle show a relatively obvious non-linear characteristic, the two still show a relatively stable linear relationship in the short term).

[0030] In some embodiments of this specification, the first linear control function of printing air pressure, which is only related to the continuous printing time and corresponds to the target characteristic printing material and can guide the printing of target linewidth and target lineth in the initial time stage, includes: For printing materials with target characteristics, during the initial time phase, the printing air pressure is adjusted at preset time intervals (the preset time intervals can be, for example, 20 min, 25 min, or 30 min, i.e., set to a duration that can affect the line width and line thickness; shorter durations such as 2 min, 3 min, or 5 min are not recommended as they are not very meaningful). This ensures that the actual line width and actual line thickness obtained after each printing air pressure adjustment reach the target line width and target line thickness, and the corresponding printing air pressure and continuous printing duration are recorded each time the target line width and target line thickness are reached. Based on the printing pressure and continuous printing time corresponding to each time the target line width and target line thickness are reached, a first linear control function of printing pressure, which is only related to the continuous printing time, is obtained to guide the printing of the target line width and target line thickness in the initial time stage.

[0031] In other words, it is understandable that for the initial time stage, it is still necessary to obtain the data required for fitting the linear control function of the first printing pressure. That is, the printing pressure and continuous printing duration corresponding to each of the multiple time points. Furthermore, the linear control function of the first printing pressure corresponding to the initial time stage can be obtained by fitting a linear regression algorithm.

[0032] Understandably, the length of the aforementioned time period is crucial in this scheme. If it's too long, the printing pressure and continuous printing duration within that time period will likely exhibit a significant non-linear relationship. Therefore, representing the printing pressure and continuous printing duration within this time period using a linear function would reduce the control precision. If it's too short, the first linear control function for printing pressure will be updated too frequently.

[0033] Therefore, in some embodiments of this specification, the duration of each time phase is equal, and the duration setting of the time phase includes: Obtain printing materials with different properties; Each printing material is used for printing operations, and each printing operation includes adjusting the printing air pressure at preset time intervals to ensure that the actual line width and actual line thickness reach the target line width and target line thickness after each printing air pressure adjustment. The printing air pressure and continuous printing time at each time the target line width and target line thickness are reached are recorded, thereby obtaining the printing dataset corresponding to each printing material. Based on the printing dataset corresponding to each printing material, the time-pressure fitting curve corresponding to each printing material is obtained; Based on the time-pressure fitting curve corresponding to each printing material, the preferred linear time length corresponding to each printing material is obtained (that is, the time-pressure fitting curve is divided by the preferred linear time length, and each segment basically shows a linear state). Based on the preferred linear time length corresponding to each printing material, the duration of the time stage is set (i.e., the minimum value among all preferred linear time lengths can be taken as the duration of the time stage).

[0034] Based on the time-pressure fitting curve corresponding to each printing material, a time length can be obtained so that the line segments obtained by dividing each fitting curve through this time length are basically linear. The duration of the time segment can be set to, but is not limited to, 2 hours, 3 hours, etc.

[0035] For example, if there are fitted curve 1, fitted curve 2, and fitted curve 3, further: The fitted curves 1, 2, and 3 were each divided into time intervals of 0–2 hours, 2–4 hours, 4–6 hours, and so on. Ultimately, the line segments for each time interval on the fitted curves 1, 2, and 3 exhibited essentially a linear relationship.

[0036] Furthermore, it should be noted that the curve results obtained through the operation described in this embodiment also prove the correctness of the result that although the air pressure data and the corresponding continuous printing duration data at each moment exhibit relatively obvious non-linear characteristics, ensuring that the line thickness and line width remain consistent throughout the long production cycle, they still show a relatively stable linear relationship in a short period of time. This also verifies the feasibility of the solution provided in the embodiments of this specification.

[0037] In some embodiments of this specification, the step of obtaining the second printing pressure linear control function, which is only related to the product of the line width and the line thickness, based on the compensated air pressure value, compensated line width, compensated line thickness, stage air pressure value, stage line width, and stage line thickness, for the next time stage includes: Based on the compensated air pressure value, compensation line width, compensation line thickness, stage air pressure value, stage line width, and stage line thickness, the second proportional coefficient term in the second printing air pressure linear control function is obtained; Based on the obtained second proportional coefficient term, stage air pressure value, stage line width, and stage line thickness, the second intercept term in the second printing air pressure linear control function is obtained. Based on the obtained second proportional coefficient term and second intercept term, the second linear control function of printing air pressure corresponding to the next time stage is obtained, which is only related to the product of line width and line thickness.

[0038] The second printing air pressure linear control function is: P a2 =k2*(W2*H2)+b2; Among them, P a2 The second printing air pressure parameter is represented by k2, the second proportional coefficient parameter is represented by b2, the second intercept parameter is represented by W2, the second line width parameter is represented by H2, and the second line thickness parameter is represented by H2. k2=(P1-P2) / (W1*H1-W2*H2), b2=P1- k2*(W1*H1); Wherein, P1 represents the stage pressure value, P2 represents the compensated pressure value, W1 represents the stage line width, W2 represents the compensated line width, H1 represents the stage line thickness, and H2 represents the compensated line thickness.

[0039] It should be noted that the preset compensation air pressure value is used to adjust the printing air pressure immediately after the end of the time period. Therefore, the impact of the continuous printing time variation on the line width and line thickness during this time difference is almost negligible. Thus, a linear relationship between the air pressure and the product of line width and line thickness can be constructed (i.e., the second printing air pressure linear control function).

[0040] Furthermore, the above linear relationship can be proven through the following experimental procedures: (1) Obtain printing materials with different properties, and divide each type into multiple parts, for example, it can be divided into 3 parts of printing material 1, 3 parts of printing material 2, and 3 parts of printing material 3; (2) Set different pressure increments, such as 1 psi, 2 psi, 5 psi, etc.; (3) For each type of printing material, three different pressure increments were used to increase the printing pressure. For example, for printing material 1, the printing operation was carried out with pressure increments of 1 psi, 2 psi, and 5 psi, resulting in a total of 9 experimental groups.

[0041] (4) For each experimental group, the air pressure data, line width data, and line thickness data during the process are collected as a data group at short preset time intervals (e.g., 10 min). (5) It can be found that each set of data can be used to construct a linear relationship between the product of air pressure and line width and line thickness.

[0042] Therefore, the conclusion that a linear relationship between the product of air pressure and linewidth / thickness can be established in a relatively short time is demonstrated. This also verifies the feasibility of the solution provided in the embodiments of this specification.

[0043] In some embodiments of this specification, the step of updating the parameters of the first printing pressure linear control function corresponding to the previous time stage based on the second printing pressure linear control function, target line width, and target line thickness corresponding to the next time stage, to generate a first printing pressure linear control function that can guide the printing of the target line width and target line thickness in the next time stage and is only related to the continuous printing duration, includes: Substitute the target line width and target line thickness into the second printing pressure linear control function corresponding to the next time stage to obtain the target pressure; Based on the target air pressure, the stage air pressure value, and the duration of the time stage, the air pressure compensation amount is obtained. Based on the target air pressure and air pressure compensation amount, the first proportional coefficient term and the first intercept term in the first printing air pressure linear control function corresponding to the previous time stage are updated to generate a first printing air pressure linear control function that can guide the printing of the target line width and target line thickness in the next time stage and is only related to the continuous printing time.

[0044] Based on the above, we know that Pa2 = k2*(W2*H2) + b2. Substituting the target line width and target line thickness further, we can obtain the target air pressure = k2*(W...). 目标 *H 目标 )+b2. This target air pressure is the air pressure value that can achieve the target line width and target line thickness at the current moment, and therefore can be used as the first intercept term in the first printing air pressure linear control function corresponding to the next time stage.

[0045] Furthermore, the principle of obtaining the air pressure compensation amount based on the target air pressure, the stage air pressure value, and the duration of the time stage is as follows: because within the duration of the previous time stage, the difference between the final stage air pressure value and the original target air pressure value that could achieve the target line width and target line thickness is (target air pressure - stage air pressure value), therefore, the average air pressure difference at each moment is: (target air pressure - stage air pressure value) / duration of the time stage. Thus, the air pressure difference at each moment can be used as the air pressure compensation amount to update the first proportional coefficient term in the first printing air pressure linear control function corresponding to the previous time stage, which can then be used as the first proportional coefficient term in the first printing air pressure linear control function corresponding to the next time stage.

[0046] In some embodiments of this specification, updating the parameters of the first proportional coefficient term and the first intercept term in the first printing pressure linear control function corresponding to the previous time stage based on the target air pressure and the air pressure compensation amount includes: The parameters of the first intercept term in the linear control function of the first printing pressure corresponding to the previous time stage are updated based on the target air pressure. The parameters of the first proportional coefficient term in the first linear control function of the first printing air pressure corresponding to the previous time stage are updated based on the air pressure compensation amount.

[0047] In some embodiments of this specification, the first printing air pressure linear control function is: P a1 =k1*t1+b1; Among them, P a1 The first printing air pressure parameter is represented by k1, the first proportional coefficient is represented by b1, the first intercept is represented by t1, and the continuous printing duration is represented by t1. (Note: The duration of continuous printing for each time period should be recalculated from 0.)

[0048] The parameter update of the first intercept term b1 in the linear control function of the first printing pressure corresponding to the previous time stage based on the target air pressure is to replace the parameter value corresponding to the first intercept term b1 with the target air pressure.

[0049] The parameter update of the first proportional coefficient term k1 in the first printing pressure linear control function corresponding to the previous time stage is based on the air pressure compensation amount. Specifically, the air pressure compensation amount is used as the increment of the parameter value of the first proportional coefficient term in the first printing pressure linear control function corresponding to the previous time stage, thereby updating the parameter of the first proportional coefficient term in the first printing pressure linear control function corresponding to the previous time stage. For example, assuming the parameter value of the first proportional coefficient term in the first printing pressure linear control function corresponding to the previous time stage is 5 psi, and the air pressure compensation amount is 2 psi, then the parameter value of the first proportional coefficient term in the first printing pressure linear control function corresponding to the next time stage is 7 psi.

[0050] The formula for calculating the air pressure compensation is (target air pressure - stage air pressure value) / duration of the time stage.

[0051] The foregoing has described specific embodiments of this specification. Other embodiments are within the scope of the appended claims.

The second printing parameter acquisition module 203 adjusts the printing air pressure based on the preset compensation air pressure value to obtain the compensation line width and compensation line thickness after the air pressure adjustment, and records the compensation air pressure value. The second function acquisition module 204 obtains the second printing pressure linear control function corresponding to the next time stage based on the compensated air pressure value, compensated line width, compensated line thickness, stage air pressure value, stage line width, and stage line thickness, which is only related to the product of the line width and line thickness. The function update module 205 updates the parameters of the first printing pressure linear control function corresponding to the previous time stage based on the second printing pressure linear control function, target line width, and target line thickness corresponding to the next time stage, so as to generate a first printing pressure linear control function that can guide the printing of the target line width and target line thickness in the next time stage and is only related to the continuous printing duration.
