Description

Technical Field

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

[0002] In the printing process, print quality is primarily determined by the consistency of line thickness and width. While ensuring highly stable printing, air pressure regulation directly determines variations in line thickness and width. Furthermore, the amount of time the material remains in the barrel can lead to dynamic changes in material properties, particularly viscosity. This can cause drift in print output parameters, resulting in deviations from standard line thickness and width requirements, deteriorating product uniformity, and even leading to quality issues such as decreased yield, abnormal morphology, and non-discharge.

[0003] Furthermore, due to the nonlinear dynamic changes in material properties caused by the increasing time the material spends in the barrel, the air pressure data that ensures consistent line thickness and width at each moment during a long production cycle and the corresponding continuous printing time data at each moment also exhibit significant nonlinear characteristics. This means that the construction of the air pressure control function requires a large amount of fitting data to ensure its control effect.

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

[0006] The technical solution is as follows: In a first aspect, an embodiment of this specification provides a method for generating a printing air pressure control function, comprising: Obtaining a first printing pressure linear control function corresponding to the target characteristic printing material, which can guide printing to obtain the target line width and target line thickness in the initial time stage and is only related to the continuous printing time; When the end of the current time stage is reached, the stage line width and stage line thickness obtained by printing under the guidance of the first printing air pressure linear control function corresponding to the current time stage are obtained, and the stage air pressure value at this time is recorded; Adjusting the printing air pressure based on the preset compensation air pressure value to obtain the compensated line width and compensated line thickness printed after the air pressure adjustment, and recording the compensated air pressure value; Based on the compensated air pressure value, the compensated line width, the compensated line thickness, the stage air pressure value, the stage line width, and the stage line thickness, a second printing air pressure linear control function corresponding to the next time stage and only related to the product of the line width and the line thickness is obtained; 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 time and can guide printing to obtain the target line width and target line thickness in the next time stage; The corresponding steps above are repeated to sequentially generate the first printing pressure linear control function corresponding to each time stage.

[0012] As a preferred solution, the method 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 period based on the target pressure and the pressure compensation amount includes: Based on the target air pressure, a parameter of a first intercept term in a first printing air pressure linear control function corresponding to a previous time period is updated; The first proportional coefficient term in the first printing air pressure linear control function corresponding to the previous time period is updated based on the air pressure compensation amount.

[0013] As a preferred solution, the first printing pressure linear control function is Pa1=k1*t1+b1; Wherein, Pa1 represents the first printing pressure parameter item, k1 represents the first proportional coefficient item, b1 represents the first intercept item, and t1 represents the continuous printing time; The parameter of the first intercept term in the first printing pressure linear control function corresponding to the previous time period is updated based on the target pressure, that is, the parameter value corresponding to the first intercept term is replaced by the target pressure; The parameter of the first proportional coefficient term in the first printing pressure linear control function corresponding to the previous time period is updated based on the pressure compensation amount, that is, the pressure compensation amount is used as an increment of the parameter value of the first proportional coefficient term in the first printing pressure linear control function corresponding to the previous time period, so as to update the parameter of the first proportional coefficient term in the first printing pressure linear control function corresponding to the previous time period; The air pressure compensation amount is calculated as (target air pressure - stage air pressure value) / time stage duration.

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

[0027] First, a first linear pressure control function is obtained to guide printing to the target line width and thickness during the initial time period. At the end of each time period, based on the stage line width, stage line thickness, and stage pressure values ​​obtained under the guidance of the first linear pressure control function, combined with the compensated line width, compensated line thickness, and compensated pressure values ​​obtained after adjustment with a preset compensation pressure value, a second linear pressure control function related only to the product of line width and line thickness is derived. Finally, based on this second linear pressure control function and the target line width and target thickness, the parameters of the first linear pressure control function are updated to generate a new first linear pressure control function, thereby forming a dual closed-loop control mechanism. In other words, only the fitting data for constructing the first linear pressure control function corresponding to the initial time period needs to be obtained in the early stages. While ensuring control accuracy, the complexity of constructing the initial pressure control function is greatly reduced.

[0028] It should be noted that the above solution is applicable to scenarios where only line width and thickness need to be maintained during printing, without requiring personalized adjustments. Furthermore, only the printing pressure parameter is changed during the entire printing process, with other printing parameters remaining unchanged. The characteristics of the printing material may include, but are not limited to, viscosity, density, surface tension, and so on.

[0029] In addition, it should be noted that the implementation of the above solution must be based on the fact that if the line width and line thickness remain unchanged during the printing process, the printing pressure and the continuous printing time from the start of printing to the end of printing will still show a relatively stable linear relationship in a short period of time (that is, although the pressure value data that can ensure the consistency of line thickness and line width at each moment in a long production cycle and the corresponding continuous printing time data at each moment show relatively obvious nonlinear characteristics, the two still show a relatively stable linear relationship in a short period of time).

[0030] In some embodiments of the present specification, the first printing pressure linear control function corresponding to the target characteristic printing material, which can guide the printing to obtain the target line width and target line thickness in the initial time period and is only related to the continuous printing time, includes: For printing materials with target characteristics, during the initial time period, adjust the printing pressure at preset time intervals (the preset time intervals can be, for example, 20 minutes, 25 minutes, or 30 minutes, i.e., a time interval that can affect line width and thickness. Shorter time intervals such as 2 minutes, 3 minutes, or 5 minutes are not recommended, as otherwise they will be of little significance) so that the actual printed line width and thickness reach the target line width and thickness after each adjustment of the printing pressure. Record the corresponding printing pressure and continuous printing time each time the target line width and 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 printing pressure linear control function corresponding to the target characteristic printing material is obtained, which can guide the printing of the target line width and target line thickness in the initial time stage and is only related to the continuous printing time.

[0031] As you can understand, for the initial time period, it's still necessary to obtain the data necessary to fit the first printing pressure linear control function. This includes the printing pressure and printing duration corresponding to multiple time points. Furthermore, a linear regression algorithm can be used to fit the first printing pressure linear control function for the initial time period.

[0032] As you can understand, the length of the aforementioned time period is crucial in this solution. If it's too long, the print pressure and duration within that time period will likely exhibit a significant nonlinear relationship. Therefore, if the print pressure and duration within that time period are represented by a linear function, control accuracy will be reduced. If it's too short, the first print pressure linear control function will be updated too frequently.

[0033] Therefore, in some embodiments of this specification, the duration of each time stage is equal, and the duration setting of the time stage includes: Obtain printing materials with different characteristics; Performing a printing operation using each printing material, and adjusting the printing pressure at predetermined intervals so that the actual line width and thickness of the printed line reach the target line width and thickness after each adjustment of the printing pressure, and recording the corresponding printing pressure and continuous printing time each time the target line width and thickness are reached, thereby obtaining a printing data set corresponding to each printing material; Based on the printing data set corresponding to each printing material, a 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 (i.e., the time-pressure fitting curve is divided according to the preferred linear time length, and each divided line segment is substantially linear); The duration of the time phase is set based on the preferred linear time length corresponding to each printed material (ie, the minimum value of all preferred linear time lengths may be taken as the duration of the time phase).

[0034] That is, based on the time-pressure fitting curve corresponding to each printed material, a time period can be obtained so that each line segment formed by dividing the fitting curve by the time period is substantially linear. The time period can be set to, but is not limited to, 2 hours, 3 hours, etc.

[0035] For example, there are fitting curve 1, fitting curve 2, and fitting curve 3. Further: Fitting curve 1, fitting curve 2, and fitting curve 3 are divided into 0-2 hour intervals, 2-4 hour intervals, 4-6 hour intervals, etc. Finally, the line segments of each time interval on fitting curve 1, fitting curve 2, and fitting curve 3 are basically linear.

[0036] Furthermore, it should be noted that the curves obtained through the operations described in this embodiment also demonstrate the correctness of the result that, although the air pressure data and the corresponding continuous printing duration data at each moment, which ensure consistency in line thickness and width at each moment during a long production cycle, exhibit relatively obvious nonlinear characteristics, they still exhibit a relatively stable linear relationship over short periods of time. This further verifies the feasibility of the solutions provided in the embodiments of this specification.

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

[0038] Among them, the second printing pressure linear control function is: P a2 =k2*(W2*H2)+b2; Among them, P a2 represents the second printing pressure parameter item, k2 represents the second proportional coefficient item, b2 represents the second intercept item, W2 represents the second line width parameter item, and H2 represents the second line thickness parameter item; K2=(P1-P2) / (W1*H1-W2*H2), b2=P1-k*(W1*H1); Among them, P1 represents the stage air pressure value, P2 represents the compensated air 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 time stage reaches the end point. Therefore, the impact of the change in continuous printing time on the line width and line thickness during this time difference is almost negligible. Therefore, a linear relationship between the above-mentioned air pressure and the product of line width and thickness can be constructed (i.e., the second printing air pressure linear control function).

[0040] In actual operation, the following experimental operations can also prove the validity of the above linear relationship: (1) Obtain printing materials with different characteristics, and divide each into multiple parts, for example, 3 parts of printing material 1, 3 parts of printing material 2, and 3 parts of printing material 3; (2) Set different air pressure increments, such as 1psi, 2psi, 5psi, etc. (3) For each printing material, three different air pressure increments were used to perform the printing pressure increment operation. For example, for printing material 1, the air pressure increments of 1 psi, 2 psi, and 5 psi were used for printing, so there were a total of 9 experimental groups.

[0041] (4) For each experimental group, the air pressure data, line width data, and line thickness data in the process are taken as a data set at a short preset time interval (e.g., 10 min); (5) Finally, it can be found that for each data set, a linear relationship between air pressure and the product of line width and line thickness can be constructed.

[0042] Therefore, the conclusion that a linear relationship between air pressure and the product of line width and line thickness can be established in a relatively short time is correct, and the feasibility of the solution provided in the embodiments of this specification is verified.

[0043] In some embodiments of the present specification, the updating of parameters of the first printing pressure linear control function corresponding to the previous time stage based on the second printing pressure linear control function, the target line width, and the target line thickness corresponding to the next time stage to generate the first printing pressure linear control function related only to the continuous printing duration and capable of guiding printing to obtain the target line width and target line thickness in the next time stage includes: Substituting 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 the 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 is only related to the continuous printing time and can guide the printing to obtain the target line width and target line thickness in the next time stage.

[0044] Based on the above, we know that: Pa2=k2*(W2*H2)+b2, and further substituting the target line width and target line thickness into the target pressure can be obtained as: k2*(W 目标 *H 目标 The target air pressure is the air pressure value that can achieve the target line width and target line thickness at the current moment, and thus 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: because within the duration of the previous time stage, the difference between the final stage air pressure value and the target air pressure value that can originally achieve the target line width and target line thickness is (target air pressure-stage air pressure value), so the air pressure value averaged at each moment is: (target air pressure-stage air pressure value) / duration of the time stage, and then the air pressure value difference at each moment can be used as the air pressure compensation amount to update the parameters of the first proportional coefficient item in the first printing air pressure linear control function corresponding to the previous time stage, which can be used as the first proportional coefficient item in the first printing air pressure linear control function corresponding to the next time stage.

[0046] In some embodiments of the present specification, the updating of the first proportional coefficient term and the first intercept term in the first printing pressure linear control function corresponding to the previous time period based on the target pressure and the pressure compensation amount includes: Based on the target air pressure, a parameter of a first intercept term in a first printing air pressure linear control function corresponding to a previous time period is updated; The first proportional coefficient term in the first printing air pressure linear control function corresponding to the previous time period is updated based on the air pressure compensation amount.

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

[0048] The parameter of the first intercept term b1 in the first printing pressure linear control function corresponding to the previous time period is updated based on the target pressure, that is, the parameter value corresponding to the first intercept term b1 is replaced by the target pressure.

[0049] The parameter update of the first proportional coefficient term k1 in the first printing air pressure linear control function corresponding to the previous time period based on the air pressure compensation amount is performed by using the air pressure compensation amount as an 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 period to update the parameter of the first proportional coefficient term in the first printing air pressure linear control function corresponding to the previous time period. That is, assuming that the parameter value of the first proportional coefficient term in the first printing air pressure linear control function corresponding to the previous time period is 5 psi and the air pressure compensation amount is 2 psi at this time, the parameter value of the first proportional coefficient term in the first printing air pressure linear control function corresponding to the next time period is 7 psi.

[0050] The air pressure compensation amount is calculated as (target air pressure - stage air pressure value) / duration of the time stage.
