[0023] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

In addition, although the functional modules are divided in the device schematic diagram, and the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from the module division in the device schematic diagram or the order in the flowchart.
[0025] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs.

The term "and / or" used in the present application includes any and all combinations of one or more related listed items.
[0026] Piezoelectric inkjet printing technology is a printing technology that uses piezoelectric effect to achieve ink ejection. Its working principle is mainly that a piezoelectric ceramic sheet is located inside the inkjet head. When ink ejection is needed, the control circuit applies a voltage signal to the piezoelectric ceramic sheet. The piezoelectric ceramic sheet changes in size and rapidly contracts or expands to produce high-frequency vibrations when subjected to an electric field. This vibration force pushes the ink from the ink channel to the vicinity of the nozzle and ejects it out. By controlling the frequency and amplitude of the voltage signal, the ink ejection amount and ejection speed can be accurately controlled, thereby achieving high-quality printing.
[0027] However, if the time of waveform superposition between the waveforms generated by the piezoelectric ceramic sheet is set arbitrarily, it will have a significant impact on printing. The time of waveform superposition refers to the interval time between two or more waveforms, i.e., the time interval between adjacent waveforms. The length of this time interval will affect the ink ejection and printing quality.
[0028] To solve the above problems, the embodiment of the present application provides a kind of inkjet printing control method, device, inkjet printer and storage medium, by accurately adjusting the time of waveform superposition, ensure that the main wave waveform energy of second waveform can be with the afterwave waveform energy of first waveform in the ink channel before ink is not ejected from nozzle waveform energy of ink superposition, produce a superimposed total waveform energy to neutralize the afterwave waveform energy of first waveform, to eliminate the interference of afterwave waveform energy to inkjet printing, ensure the stability and consistency of ink ejection, improve the printing quality.
[0029] Please refer to Figure 1 , Figure 1 It is the flow chart of a kind of inkjet printing control method provided by the embodiment of the present application, as Figure 1 The inkjet printing control method provided by the embodiment of the present application is applied to inkjet printer, the piezoelectric ceramic piece is provided on the inkjet printer, and the method comprises:
[0030] S11: the oscillation frequency of the piezoelectric ceramic piece is acquired;
[0031] S12: the superposition time of the main wave waveform energy of second waveform and the afterwave waveform energy of first waveform is calculated according to the oscillation frequency;Wherein, the first waveform and the second waveform are adjacent waveforms generated when the piezoelectric ceramic piece deforms;
[0032] S13: the waveform starting time of the second waveform is set according to the superposition time;
[0033] S14: the piezoelectric ceramic piece is controlled to generate deformation at the waveform starting time, so that the main wave waveform energy of the second waveform and the afterwave waveform energy of the first waveform are superimposed in waveform energy.
[0034] Specifically, please refer to Figure 2 And Figure 3 , Figure 2 It is the schematic diagram of waveform energy motion track, Figure 3 It is the schematic diagram of waveform change process and waveform superposition time. As Figure 2 And Figure 3As shown, the piezoelectric ceramic sheet deforms up and down to generate wave energy when subjected to an electric field, which is transmitted in the ink channel (arrow indicates the direction of energy propagation) to further eject ink from the nozzle. That is, after the first wave of the piezoelectric ceramic sheet deforms to generate a first wave, the wave energy of the first wave begins to transmit in the ink channel (a wave stage). Among them, the wave energy of the first wave is divided into main wave energy and residual wave energy, the main wave energy of the first wave transmits to the nozzle direction, and the residual wave energy of the first wave continues to transmit in the ink channel, and transmits to the end of the ink channel away from the nozzle (b wave stage; wherein 1 represents the main wave energy of the first wave, and 1' represents the residual wave energy of the first wave). When the residual wave energy of the first wave encounters the end (seal), it will turn around to form a reflected energy moving towards the nozzle. At this time, the main wave energy of the first wave pushes the ink out of the nozzle (C wave stage). It can be understood that the best opportunity for the main wave energy of the first wave to transmit to the nozzle and further eject ink droplets from the nozzle is Figure 3 As shown, the first wave peak of the A wave represents the main wave energy of the first wave pushing the ink out of the nozzle to form a main point (at this time the piezoelectric ceramic sheet bends to the highest point in the ink channel), wherein the wave energy of the first wave generated by the piezoelectric ceramic sheet is similar to a swing, and the main point generated by the first ejection of ink from the nozzle is similar to pulling the swing with a person sitting on it to the highest point, and then pushing it forward until it swings to the highest point, and then continuously swings back and forth in a free state (at this time the residual wave energy of the first wave is generated).
[0035] Among them, if the piezoelectric ceramic sheet deforms to generate a second wave immediately after the main wave energy of the first wave disappears, the residual wave energy of the second wave will collide with the residual wave energy of the first wave, thereby generating disturbance in the ink channel and affecting normal ink ejection. It can be understood that if the residual wave energy of the second wave generated by the second wave deforming immediately after the main wave energy of the first wave ends will collide with the residual wave energy of the first wave, which is similar to pushing the swing back when it swings to the highest point and passes the middle position, at this time part of the pushing force needs to overcome the swing force to provide the forward pushing force, so it is necessary to accurately control the superposition time of the wave energy of adjacent waves to effectively avoid the above situation.
[0036] It can be understood that, since the main wave energy of the second wave is much larger than the residual wave energy of the first wave, if the superposition time of the wave energy of adjacent waves is too short, the main wave energy of the second wave will catch up with and exceed the residual wave energy of the first wave (i.e. Figure 2In the d-wave stage, the dominant waveform energy of the second waveform exceeds the residual waveform energy of the first waveform (where 2 represents the dominant waveform energy of the second waveform and 2' represents the residual waveform energy of the second waveform). This prevents the dominant waveform energy of the second waveform from achieving optimal waveform energy superposition with the residual waveform energy of the first waveform, thus failing to eliminate the interference of the residual waveform energy of the first waveform on inkjet printing. If the superposition time of the waveform energies of adjacent waveforms is controlled for too long, the dominant waveform energy of the second waveform cannot catch up with the residual waveform energy of the first waveform in time. Consequently, the residual waveform energy of the first waveform ejects ink from the nozzle in the ink channel before the dominant waveform energy of the second waveform to form satellite dots (e.g., ...). Figure 3 The second peak of waveform A shown represents the residual wave energy of the waveform generated by the deformation of the piezoelectric ceramic sheet. This residual wave energy, after the ink in the ink channel is ejected from the nozzle, forms satellite dots, which can cause wood grain and airflow phenomena. Based on this, by precisely controlling the superposition time of the waveform energy of adjacent waveforms, the main wave energy of the second waveform catches up with the residual wave energy of the first waveform, thus performing wave energy chasing superposition and forming a total waveform energy that propels the ink in the ink channel to be ejected from the nozzle (waveform e stage). It can be understood that the total waveform energy formed is generated by the main wave energy of the second waveform minus the residual wave energy of the first waveform, eliminating the disturbance of the residual wave energy of the first waveform to inkjet printing. It should be noted that if the superposition time of the waveform energy of adjacent waveforms is not precisely controlled, both main dots and satellite dots will be generated; if the superposition time of the waveform energy of adjacent waveforms is precisely controlled, only main dots will be generated, and no satellite dots will be generated. In addition, the wave energy chasing superposition process is completed before the ink in the ink channel is ejected from the nozzle.
[0037] It should be noted that the waveforms mentioned above include, but are not limited to, the first and second waveforms, and may also include the third and fourth waveforms. The number of waveforms is not limited here, as long as the condition of adjacent waveforms is met.
[0038] This embodiment precisely controls the superposition time of waveform energy, ensuring that the main waveform energy of the second waveform catches up with the residual waveform energy of the first waveform just before the ink in the ink channel is ejected from the nozzle. This ink-chasing superposition of waveform energy forms a total waveform energy that forces the ink in the ink channel out of the nozzle. This method eliminates the interference of residual waveform energy generated by the deformation of the piezoelectric ceramic sheet on the ink ejection point, improving the accuracy and clarity of inkjet printing.
[0039] In some embodiments, such as Figure 4 As shown, the superposition time of the main point of the second waveform and the satellite point of the afterwave of the first waveform based on the oscillation frequency includes:
[0040] S121: set a waiting time according to the interval time;
[0041] S122: set a waiting time according to the interval time;
[0042] S123: calculate the superposition time according to the interval time and the waiting time.
[0043] It can be understood that by setting the interval time, the piezoelectric ceramic piece is prevented from deforming to generate the second waveform immediately after the main wave energy of the first waveform disappears, so that the residual wave energy of the second waveform will collide with the residual wave energy of the first waveform, thereby generating disturbance in the ink channel and affecting normal inkjet. In addition, the main wave energy of the second waveform generated by the deformation of the piezoelectric ceramic piece will be stronger and propagate faster than the residual wave energy of the first waveform, so a certain time delay is required before the deformation to generate the second waveform, that is, the waiting time is set according to the interval time, and then the time sum of the interval time and the waiting time is calculated as the best superposition time. Therefore, the waveform starting time of the second waveform can be accurately calculated, that is, the time sum of the waveform duration of the first waveform and the superposition time. It can be understood that when the piezoelectric ceramic piece deforms to generate the second waveform at the waveform starting time, the main wave energy of the second waveform can be superimposed with the residual wave energy of the first waveform. The present embodiment sets the interval time and the waiting time reasonably, calculates the best superposition time according to the interval time and the waiting time, so that the piezoelectric ceramic piece deforms to generate the second waveform at the waveform starting time, thereby realizing the effect of ink dot superposition and improving the accuracy and clarity of inkjet printing.
[0044] In some embodiments, the oscillation frequency of the piezoelectric ceramic sheet ranges from 30 KHz to 150 KHz. In the field of inkjet printing technology, the oscillation frequency affects the oscillation period of the piezoelectric ceramic sheet and the speed of waveform superposition. According to the oscillation frequency, the superposition time of the waveform is adjusted appropriately, so that the stable ejection of ink can be maintained, and the situation of uneven ejection or splashing can be avoided. For example, taking the Ricoh 5 printer as an example, the oscillation frequency of the piezoelectric ceramic sheet is set to 60 KHz, and it can be known that the oscillation period is 16.7us (1 / 60). The interval time between waveforms is 16.7 / 2 = 8.33us, and if the waveform time used is 40us; the printing single-point time is 40+8.33 = 48.33us, plus the phase shift of 2.08us, that is, the waveform starting time of the second waveform is 50.41us. It can be understood that, due to the difference in oscillation frequency, the superposition time of the waveform needs to be adjusted correspondingly. According to the oscillation frequency, the oscillation period can be calculated, the interval time is set to half of the oscillation period, that is, 8.33us, the waveform duration is 40us, and the waiting time is set to 2.08us. The waveform starting time of the second waveform can be calculated as 50.41us, and then the piezoelectric ceramic sheet deforms to generate the second waveform at 50.41us to achieve the effect of ink chasing superposition of waveform energy. In this embodiment, by setting a certain range of oscillation frequency, the superposition time between waveforms is adjusted according to different oscillation frequencies, so as to ensure that the waveforms can achieve the effect of ink chasing superposition of waveform energy, thereby improving the printing quality of the inkjet printer under different oscillation frequencies.
[0045] In some embodiments, the interval time of the first waveform is set according to the oscillation frequency, including:
[0046] According to the oscillation frequency, the oscillation period of the first waveform is calculated;
[0047] According to the oscillation period, the interval time of the first waveform is set, so that the interval time of the first waveform satisfies the first range.
[0048] The first range is: 2 / 5H≤Q≤2 / 3H;
[0049] Wherein, H is the oscillation period, and Q is the interval time.
[0050] It can be understood that, as shown in Figure 3 , Figure 3A schematic diagram of a waveform superposition time is shown. When the oscillation frequency is 60KHz, the oscillation period is 16.7us, the piezoelectric ceramic piece deforms to generate a first waveform under the action of an electric field, the waveform duration of the first waveform is 40us, and the residual waveform energy of the first waveform is absorbed by waiting for a quarter of a period. The absorbed residual waveform energy changes direction and provides energy to the ink in the ink channel, i.e. the interval time is half a period (8.33us). Therefore, the interval time of half a period is needed to absorb the residual waveform energy and change the direction of the residual waveform energy. In this embodiment, the interval time of the first waveform is set according to the oscillation period to absorb the residual waveform energy and change the direction of the residual waveform energy to provide energy to the ink in the ink channel. This effectively avoids the piezoelectric ceramic piece deforming to generate a second waveform immediately after the main waveform energy of the first waveform disappears, so that the residual waveform energy of the second waveform collides with the residual waveform energy of the first waveform, thereby generating disturbance in the ink channel and affecting normal ink ejection. It should be noted that the above-described interval time includes but is not limited to half a period. The interval time can be adjusted according to the different oscillation frequencies, as long as it meets the first range provided in this embodiment.
[0051] In some embodiments, the waiting time and the interval time meet the following second range:
[0052] The second range is: 1 / 5Q≤T≤1 / 3Q;
[0053] Wherein, T is the waiting time, and Q is the interval time.
[0054] After the waiting interval time, the main waveform energy of the second waveform generated by the deformation of the piezoelectric ceramic piece is stronger and propagates faster than the residual waveform energy of the first waveform. Therefore, a delay time is needed before the deformation to generate the second waveform. That is, the waiting time is set according to the interval time, and then the time sum of the interval time and the waiting time is calculated as the optimal superposition time, so as to calculate the waveform start time of the second waveform, i.e. the time sum of the waveform duration of the first waveform and the superposition time. In this embodiment, the waiting time is set according to the interval time, so that the adjacent waveforms can better superimpose the waveform energy, which helps to improve the printing accuracy and to a certain extent, alleviate the crosstalk problem. It should be noted that the above-described waiting time is not limited, as long as it meets the second range provided in this embodiment.
[0055] In some embodiments, the method further comprises:
[0056] After the control of the piezoelectric ceramic piece to deform at the waveform start time, the printing speed is adjusted in real time.
[0057] It can be understood that, in the inkjet printing technology, the adjustment of the waveform superposition time and the change of the printing speed are both for optimizing the printing quality and efficiency. Generally, the adjustment of the two parameters is interrelated, and the change of one may affect the other. Therefore, when the waveform superposition time is adjusted, the printing speed needs to be adjusted accordingly to ensure that the ink is stably ejected and excessive splashing is not generated, so as to achieve the best balance between the production efficiency and the printing quality. It should be noted that the printing speed is not limited in the embodiment, and the printing speed can be adjusted according to the specific actual application scenario.
