[0001] This invention relates to the field of inkjet printing control technology, and in particular to an inkjet control method, apparatus, equipment, medium, and program product. Background Technology

[0002] In the field of inkjet printing control technology, droplet velocity affects inkjet printing efficiency, while droplet volume and the number of satellite dots affect the printing effect and quality. Therefore, controlling droplet data is a crucial part of the inkjet printing control process. Specifically, controlling droplet data such as droplet velocity, droplet volume, and the number of satellite dots can be achieved by adjusting the inkjet printing mode of the inkjet equipment.

[0003] In existing technologies, technicians can adjust the inkjet printer's parameters to modify the inkjet printing mode, thereby changing the droplet data during inkjet printing. However, this process typically requires technicians to continuously adjust the printhead's inkjet printing mode, simulate various inkjet printer parameters, and conduct inkjet tests based on these simulated parameters to obtain suitable inkjet printer parameters, thus controlling the inkjet printer to achieve appropriate droplet parameters during inkjet printing.

[0004] Because existing technical solutions require technicians to conduct continuous simulation tests, it leads to a waste of a lot of manpower, and the efficiency of adjusting parameters is very low. Summary of the Invention

[0005] This invention provides an inkjet control method, apparatus, device, medium, and program product, which realizes automatic adjustment of the current equipment parameters of the inkjet equipment and controls the inkjet equipment to perform inkjet operation in a suitable inkjet mode, thereby solving the problems of wasting a lot of manpower and low efficiency of parameter adjustment in the prior art.

[0007] After detecting that the inkjet device has started, the current device parameters of the inkjet device and the current ink droplet parameters of the ejected ink droplets are obtained when the inkjet head of the inkjet device is performing inkjet operation.

[0008] When the current ink droplet parameters meet the adjustment conditions, based on the set parameter adjustment model, the inkjet head is controlled to perform inkjet operation by adjusting the current device parameters;

[0009] Return to the previous state and repeat the process of acquiring the current device parameters and current droplet parameters until an inkjet termination command is received.

[0010] According to a second aspect of the present invention, an inkjet control device is provided, characterized in that it comprises:

[0011] The acquisition module is used to acquire the current device parameters of the inkjet device and the current ink droplet parameters of the ejected ink droplets when the inkjet head of the inkjet device is performing inkjet operation after the inkjet device is detected to be started.

[0012] The control module is used to control the inkjet head's inkjet ejection mode when the current ink droplet parameters meet the adjustment conditions, based on a set parameter adjustment model;

[0013] The instruction receiving module is used to repeatedly execute the acquisition operation of the current device parameters and the current ink droplet parameters before receiving the inkjet end instruction.

[0014] According to a third aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0015] At least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores a computer program executable by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the inkjet control method according to any embodiment of the present invention.

[0018] The technical solution of this invention, after detecting the start of the inkjet equipment, acquires the current equipment parameters of the inkjet equipment and the current droplet parameters of the ejected ink droplets when the inkjet head performs inkjet operation. When the current droplet parameters meet the adjustment conditions, based on a set parameter adjustment model, the inkjet head's ejection mode is controlled by adjusting the current equipment parameters. This automatically adjusts the current equipment parameters of the inkjet equipment and controls the inkjet equipment to perform inkjet operation in a suitable inkjet mode. This solves the problem of wasted manpower and low efficiency caused by manually adjusting the inkjet equipment's inkjet mode, saves human resources, and improves the efficiency of adjusting the inkjet equipment's inkjet mode.

[0027] Example 1

[0028] Figure 1 This is a flowchart of an inkjet control method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where the inkjet mode of an inkjet device is adjusted and controlled. The method can be executed by an inkjet control device, which can be implemented in hardware and / or software. This inkjet control device can be configured in an electronic device, and the electronic device establishes a communication connection with the inkjet device. Figure 1 As shown, the method includes:

[0029] S101. After detecting that the inkjet device has started, obtain the current device parameters of the inkjet device and the current ink droplet parameters of the ejected ink droplets when the inkjet head of the inkjet device is performing inkjet operation.

[0030] The inkjet equipment can be an inkjet printer, dispensing machine, or other equipment capable of inkjet printing. Current equipment parameters refer to the operating parameters of the inkjet equipment during the current inkjet operation, such as the drive voltage, pulse timing parameters, and the droplet temperature required for ink ejection. Current droplet parameters refer to the parameters of the ink droplets ejected by the printhead during inkjet printing, such as the droplet's velocity during flight, droplet shape and size, or the number of satellite dots.

[0031] For example, the inkjet control device can detect the startup status of the inkjet device in real time through a communication connection established with the inkjet device. After detecting that the inkjet device is started, when the inkjet device is performing inkjet operation, the inkjet control device can obtain the current device parameters of the inkjet device by receiving the device operating parameters pre-configured in the inkjet device by the user. At the same time, it can collect data on the ejected ink droplets through various pre-set sensors to obtain the current droplet parameters of the ink droplets ejected by the inkjet head of the inkjet device in real time.

[0032] S102. When the current ink droplet parameters meet the adjustment conditions, based on the set parameter adjustment model, the inkjet head is controlled to perform inkjet operation by adjusting the current device parameters.

[0033] The adjustment conditions can be used to determine whether the inkjet printing mode of the current inkjet equipment meets the expected operating state by examining the current ink droplet parameters. The parameter adjustment model can be used to adjust the current equipment parameters of the inkjet equipment so that the inkjet printing mode of the inkjet equipment based on the adjusted equipment parameters achieves the expected operating state.

[0034] For example, the inkjet control device can determine whether the current droplet parameters meet the adjustment conditions by preset droplet parameters. If the current droplet parameters do not match the preset droplet parameters, it is determined that the current droplet parameters meet the adjustment conditions, meaning that the inkjet mode of the current inkjet device does not meet the expected working state, and the current device parameters of the inkjet device need to be adjusted. At this time, the inkjet control device can further input the acquired current device parameters into the set parameter adjustment model to obtain the adjusted device parameters output by the parameter adjustment model, thereby controlling the inkjet device to perform the inkjet operation based on the adjusted device parameters.

[0035] S103. Return to repeatedly execute the operation of obtaining the current device parameters and the current ink droplet parameters until the inkjet end command is received.

[0036] Among them, the inkjet end command can be a control command that indicates that the inkjet device has ended the inkjet operation, and is used to control the inkjet control device to stop adjusting the inkjet mode of the inkjet device.

[0037] For example, after the inkjet control device adjusts the current equipment parameters of the inkjet equipment, it can continue to acquire the adjusted current equipment parameters of the inkjet equipment and the current droplet parameters of the ink droplets ejected by the adjusted inkjet equipment. This allows for further monitoring of whether the adjusted inkjet equipment can perform inkjet operation as expected. If the expected operating state is still not achieved, the inkjet equipment can be controlled again to perform inkjet operation by further adjusting the adjusted current equipment parameters based on a set parameter adjustment model.

[0038] It should be noted that even if the adjusted inkjet equipment can achieve the expected working state, it is still necessary to return and repeat the operation of obtaining the current equipment parameters and the current ink droplet parameters. This is so that when the inkjet equipment performs inkjet operation, it can use the real-time obtained current ink droplet parameters to determine whether the inkjet operation of the inkjet equipment has been affected by environmental factors or other factors, and thus determine whether it is necessary to readjust the inkjet mode of the inkjet equipment.

[0039] When the inkjet printer completes its inkjet operation, or when the inkjet printer is manually stopped / paused, it can generate an inkjet end command and send it to the inkjet control device. Based on the received inkjet end command, the inkjet control device can determine that the inkjet operation has ended, thereby ceasing its monitoring and control of the inkjet printer.

[0040] The above-described technical solution of this embodiment, after detecting the start of the inkjet equipment, acquires the current equipment parameters of the inkjet equipment and the current droplet parameters of the ejected ink droplets when the inkjet head performs inkjet operation. When the current droplet parameters meet the adjustment conditions, based on the set parameter adjustment model, the inkjet head is controlled to perform inkjet operation by adjusting the current equipment parameters. This can automatically adjust the current equipment parameters of the inkjet equipment and control the inkjet equipment to perform inkjet operation in a suitable inkjet mode. This solves the problem of manpower waste and low efficiency caused by manually adjusting the inkjet mode of the inkjet equipment, saves human resources, and improves the efficiency of adjusting the inkjet mode of the inkjet equipment.

[0041] Based on the above embodiments, this embodiment proposes an optional embodiment, which can be further optimized from the above embodiments, including:

[0042] The current droplet parameters include the current droplet velocity, the current droplet volume, and the current number of satellite points;

[0043] The current ink droplet parameters meet the adjustment conditions, including: the current number of satellite points is greater than 0; or, the current ink droplet velocity is less than the target velocity; or, the current ink droplet volume is not equal to the target volume.

[0044] Satellite dots are typically smaller ink droplets that separate from the main droplet during inkjet printing, formed by droplet breakage and instability. The current number of satellite dots refers to the number of satellite dots that have separated from the ejected ink droplet during inkjet printing. The current droplet velocity refers to the flight speed of the ejected ink droplet during inkjet printing. The current droplet volume refers to the size of the ejected ink droplet during inkjet printing.

[0045] Understandably, during inkjet printing, a slow droplet velocity affects the inkjet printing speed. Conversely, large or small droplet sizes result in varying ink volumes on the printing medium, impacting print quality. Furthermore, the presence of satellite dots (split dots) can cause blurring, color deviations, or loss of detail in the printed image, affecting overall image quality. Therefore, adjusting the inkjet printing method can be determined by assessing whether the droplet velocity, droplet volume, and number of satellite dots meet adjustment criteria.

[0046] For example, if the current number of satellite dots is determined to be greater than 0, it is determined that the inkjet printing mode of the current inkjet device will affect the quality of the inkjet printed image, and the inkjet printing mode of the current inkjet device needs to be adjusted. Alternatively, if the current droplet velocity is determined to be less than the target velocity, it is determined that the inkjet printing rate of the current inkjet device is low, and the inkjet printing mode of the current inkjet device needs to be adjusted. Or, if the current droplet volume is determined to be different from the target volume, it is determined that the inkjet printing mode of the current inkjet device will affect the printing effect of the inkjet printed pattern, and the inkjet printing mode of the current inkjet device needs to be adjusted.

[0047] Based on the above embodiments, this embodiment also proposes an optional embodiment, which can be further optimized from the above embodiments, including:

[0048] Optionally, obtaining the current device parameters of the inkjet equipment and the current droplet parameters of the ejected ink droplets when the inkjet head performs inkjet operation includes:

[0049] Based on the communication connection with the inkjet device, the current device parameters sent by the inkjet device are received;

[0050] While the inkjet head is controlled to perform inkjet operation by the synchronous frequency controller, the point light source and CCD camera are controlled to acquire target images of the inkjet device during inkjet operation; the target images include continuous imaging images of ink droplets during flight.

[0051] The current ink droplet parameters are obtained by performing image analysis on the target image.

[0052] The frequency controller coordinates the inkjet head, point light source, and CCD camera to operate synchronously at the same frequency. The point light source and CCD camera capture target images of the high-speed ink droplets ejected by the inkjet head. The target image can be a continuous image of the high-speed ink droplets during their flight.

[0053] For example, when an inkjet printer performs inkjet printing operations using parameters preset by the user or adjusted by the inkjet control device, the printer itself stores the current device parameters for the current inkjet operation. The inkjet control device can receive these current device parameters via a communication connection with the printer, thus automatically acquiring them. Furthermore, the inkjet control device can simultaneously control the inkjet head to perform inkjet printing operations via a synchronous controller, while also controlling a point light source and a CCD camera to acquire target images during the inkjet operation. This ensures that the inkjet printing operation and target image acquisition are performed at the same frequency, enabling high-precision capture of transient images of high-speed ink droplets using visual inspection methods, resulting in continuous imaging images of the ink droplets during their flight. Furthermore, based on these continuous imaging images, image algorithms can be used to determine the shape and size of the ink droplets or the number of satellite points; the velocity of the ink droplets can be calculated by analyzing their positional changes in the continuous imaging images; or other various parameters of the ink droplets can be determined using other image analysis methods.

[0054] Understandably, obtaining the current device parameters of an inkjet printer by receiving pre-configured device operating parameters input by the user requires the user to manually output these parameters. Furthermore, after adjusting the inkjet printing mode, the user must confirm the adjusted parameters and re-enter them into the printer, resulting in poor flexibility and efficiency. Additionally, using pre-set sensors to collect data on the ejected ink droplets and obtain real-time droplet parameters requires a large number of sensor types when collecting a large number of droplet parameters, leading to high costs. Moreover, the accuracy of sensor data acquisition is poor for high-speed ink droplets ejected by the printhead.

[0055] However, the technical solution in this optional embodiment improves the efficiency of obtaining the inkjet equipment parameters by receiving the current equipment parameters sent by the inkjet equipment based on the communication connection with the inkjet equipment. Furthermore, by obtaining the current droplet parameters of the ink droplets ejected by the inkjet equipment using visual detection methods such as a synchronous controller, point light source, and CCD camera, the accuracy of obtaining the current droplet parameters of the ink droplets ejected by the inkjet equipment can be improved.

[0056] Example 2

[0057] Figure 2This is a flowchart of an inkjet control method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment further optimizes the method by including: the current device parameters include: current driving voltage, current pulse time parameter, and current droplet temperature; the current pulse time parameter includes: current pulse rise time, current pulse hold time, and current pulse fall time. Furthermore, based on the above embodiments, this embodiment further refines the implementation of the inkjet head's inkjet operation mode by adjusting the current device parameters based on a set parameter adjustment model. Figure 2 As shown, the method includes:

[0058] S201. After detecting that the inkjet device has started, obtain the current device parameters of the inkjet device and the current droplet parameters of the ejected ink droplets when the inkjet head of the inkjet device is performing inkjet operation; the current device parameters include: current driving voltage, current pulse time parameter and current droplet temperature; the current pulse time parameter includes: current pulse rise time, current pulse hold time and current pulse fall time.

[0059] It should be noted that the current driving voltage can refer to the driving voltage used by the inkjet device during inkjet operation. The current droplet temperature can refer to the droplet temperature that the inkjet device aims to reach during inkjet operation. The current pulse time parameter can refer to the time period from the initial value to the final value of the driving voltage. This parameter can further include the current pulse rise time, the current pulse hold time, and the current pulse fall time. The current pulse rise time can be the time period during which the driving voltage changes from low to high, the current pulse hold time can be the time period during which the driving voltage remains stable, and the current pulse fall time can be the time period during which the driving voltage changes from high to low.

[0060] S202. When the current droplet parameters meet the adjustment conditions, the current pulse fall time and the current droplet temperature are adjusted based on the satellite point model in the parameter adjustment model to control the number of satellite points when the inkjet head performs inkjet operation.

[0061] The satellite dot model in the parameter adjustment model can be used to force the number of satellite dots in the ink droplet to zero. It should be noted that in the field of inkjet printing technology, satellite dots significantly affect the quality of inkjet printed patterns. Therefore, in this embodiment, when the current ink droplet parameters meet the adjustment conditions, the satellite dot model in the parameter adjustment model is used first to force the number of satellite dots to zero. Only after ensuring that the number of satellite dots is zero are other parameters of the ink droplets ejected by the inkjet equipment adjusted.

[0062] It should be further noted that the current pulse fall time can affect the breakup speed of the ink column at the tail end during inkjet printing, thus affecting the number of satellite dots. For example, increasing the current pulse fall time results in a slower breakup speed, a longer breakup time, and higher stability, thereby reducing the number of satellite dots. Furthermore, droplet temperature can affect droplet viscosity, thus influencing the number of satellite dots. For instance, increasing droplet temperature reduces the imbalance between droplet surface tension and viscous forces, thus reducing the number of satellite dots. Therefore, the number of satellite dots can be controlled by adjusting the current pulse fall time and droplet temperature of the inkjet printer.

[0063] For example, when the current droplet parameters meet the adjustment conditions, the number of satellite points in the current droplet parameters can be input into the satellite point model in the parameter adjustment model. The satellite point model in the parameter adjustment model can determine the adjustment amount of the current pulse fall time and the current droplet temperature of the inkjet device by the number of satellite points of the ink droplets ejected when the inkjet device performs inkjet operation. This allows for the regulation of the current pulse fall time and the current droplet temperature of the inkjet device, so that when the inkjet device performs inkjet operation based on the adjusted pulse fall time and the adjusted droplet temperature, the number of satellite points of the ejected ink droplets is zero.

[0064] S203. Based on the speed model in the parameter adjustment model, the current pulse rise time and the current driving voltage are adjusted to control the ink droplet speed when the inkjet head performs inkjet operation.

[0065] Among them, the velocity model in the parameter adjustment model can be used to control the flight speed of the ink droplets ejected by the inkjet equipment during inkjet operation.

[0066] It's important to note that the current driving voltage of an inkjet printer determines the deformation of the piezoelectric element, directly affecting the ejection pressure of the printhead. Higher ejection pressure results in faster droplet velocity. However, a higher driving voltage isn't always better. High voltage can cause severe droplet splitting, producing secondary satellite dots. Conversely, low voltage results in lower ejection pressure and slower droplet velocity, impacting printing speed. Therefore, the driving voltage should be maintained within the optimal range preset by technicians. Furthermore, the pulse rise time affects the initial acceleration of the droplet during flight, thus influencing its velocity. Therefore, adjusting the current driving voltage and pulse rise time allows for control of droplet velocity during inkjet printing.

[0067] For example, the current pulse rise time and current drive voltage of the inkjet device can be input into the speed model in the parameter adjustment model. The speed model in the parameter adjustment model can determine the optimal pulse rise time and target drive voltage of the inkjet device based on the target droplet speed that can meet the rate requirements of the inkjet device, and adjust the current pulse rise time and current drive voltage of the inkjet device based on the optimal pulse rise time and target drive voltage, thereby controlling the droplet speed when the inkjet head performs inkjet operation.

[0068] S204. The current pulse holding time is adjusted based on the volume model in the parameter adjustment model to control the ink droplet volume when the inkjet head performs inkjet operation.

[0069] Among them, the volume model in the parameter adjustment model can be used to control the size of the ink droplets ejected by the inkjet equipment during inkjet operation.

[0070] It should be noted that, without changing the hardware of the inkjet printer, the current pulse hold time affects the continuous thrust during inkjet printing, thus affecting the droplet size. For example, a longer current pulse hold time results in a longer continuous thrust during inkjet printing, leading to a larger droplet size. Therefore, the size of the ink droplets ejected during inkjet printing can be controlled by adjusting the current pulse hold time.

[0071] For example, the current pulse hold time of the inkjet device can be input into the volume model in the parameter adjustment model. The volume model in the parameter adjustment model can determine the optimal pulse hold time of the inkjet device based on the target ink droplet volume that meets the effect requirements of the inkjet printed pattern, and adjust the current pulse hold time of the inkjet device based on the optimal pulse hold time, thereby controlling the ink droplet volume when the inkjet head performs inkjet operation.

[0072] S205. Return to repeatedly execute the operation of obtaining the current device parameters and the current ink droplet parameters until the inkjet end command is received.

[0073] The above-described technical solution of this invention controls the number of satellite points during inkjet printing by adjusting the current pulse fall time and the current droplet temperature based on the satellite point model in the parameter adjustment model, controlling the current pulse rise time and the current driving voltage based on the velocity model in the parameter adjustment model, controlling the droplet velocity during inkjet printing, and controlling the current pulse hold time based on the volume model in the parameter adjustment model, controlling the droplet volume during inkjet printing. This achieves automatic adjustment of the droplet velocity, droplet volume, and number of satellite points during inkjet printing, saving manpower, improving the efficiency of adjusting the droplet velocity, droplet volume, and number of satellite points, and ensuring the inkjet printing rate and the quality and effect of the inkjet printing results.

[0074] Based on the above embodiments, this embodiment proposes an optional embodiment. This optional embodiment can further optimize the number of satellite points when the inkjet head performs inkjet operation by adjusting the current pulse fall time and the current droplet temperature based on the satellite point model in the parameter adjustment model, in addition to the above embodiments.

[0075] The pulse descent time adjustment and droplet temperature adjustment are determined based on the dynamic adjustment coefficient in the satellite point model and the current number of satellite points, so as to regulate the current pulse descent time and the current droplet temperature.

[0076] The inkjet head is controlled to perform inkjet operation based on the adjusted pulse fall time and adjusted droplet temperature, and the number of adjusted satellite dots is detected.

[0077] If the adjusted number of satellite points is detected to be non-zero, the dynamic adjustment coefficient is adjusted, and based on the adjusted dynamic adjustment coefficient, the operation of adjusting the current pulse descent time and the current droplet temperature is re-executed.

[0078] If the number of satellite points after adjustment is detected to be 0, the operation of adjusting the current pulse descent time and the current droplet temperature is terminated.

[0079] The dynamic adjustment coefficient can be obtained after training the satellite point model or pre-calibrated, and is used to calculate the pulse fall time adjustment and droplet temperature adjustment of the inkjet equipment.

[0080] For example, the number of satellite dots of the ink droplets ejected by the inkjet device can be input into the satellite dot model. The satellite dot model can determine the pulse fall time adjustment amount using dynamic adjustment coefficients in the satellite dot model and the input number of satellite dots. For example, through Δt fallThe pulse fall time adjustment is calculated using α*S*t, where Δt fall α is the pulse fall time adjustment amount, S is the number of input satellite points, and t is the current pulse fall time of the inkjet device.

[0081] Furthermore, the satellite dot model can determine the droplet temperature adjustment amount by using the input number of satellite dots and a pre-determined increase in droplet temperature for each reduction in the number of satellite dots. For example, through... To calculate the droplet temperature adjustment amount, where ΔT is the droplet temperature adjustment amount. The ink droplet temperature is increased by a predetermined amount for each reduction in the number of satellite points, where S is the number of satellite points input.

[0082] After calculating the pulse fall time adjustment and the droplet temperature adjustment, the current pulse fall time and the current droplet temperature of the inkjet equipment can be adjusted, and the number of satellite points when the inkjet equipment performs inkjet operation with the adjusted pulse fall time and the adjusted droplet temperature can be detected by visual inspection.

[0083] If the adjusted number of satellite points is not zero, it indicates that the adjustment amount of pulse fall time and droplet temperature is too small. The dynamic adjustment coefficient can be increased, and the adjustment amount of pulse fall time and droplet temperature can be recalculated based on the adjusted dynamic adjustment coefficient to enhance the parameter adjustment of the inkjet equipment. Then, the operation of adjusting the current pulse fall time and droplet temperature is returned until the adjusted number of satellite points is zero.

[0084] Based on the above embodiments, this embodiment also proposes an optional embodiment. This optional embodiment can further optimize the control of the ink droplet speed during inkjet printing by adjusting the current pulse rise time and the current driving voltage based on the speed model in the parameter adjustment model, in addition to the above embodiments. This includes:

[0085] Obtain the target ink droplet velocity;

[0086] Within the preset range of changes in the current pulse rise time, determine the optimal pulse rise time corresponding to the maximum ink droplet velocity;

[0087] Based on the pre-established correlation between pulse rise time, droplet velocity, and driving voltage in the velocity model, the target driving voltage is determined according to the target droplet velocity and the optimal pulse rise time.

[0088] Determine whether the target driving voltage is within a preset range;

[0089] If so, the optimal pulse rise time is determined as the target pulse rise time, and the inkjet head is controlled to perform inkjet operation based on the target pulse rise time and the target drive voltage.

[0090] If not, the optimal pulse rise time is reduced, and based on the reduced optimal pulse rise time, the operation of determining the target drive voltage is returned to be performed again.

[0091] The target droplet velocity refers to the droplet velocity that the user, based on experience, sets to meet the inkjet rate requirements of the inkjet equipment. The current pulse rise time adjustment range can be a time interval determined by using the current pulse rise time of the inkjet equipment as the midpoint of the interval. The preset range can be the optimal range of the drive voltage preset by the user to avoid affecting the secondary generation of satellite points. The target pulse rise time and target drive voltage can be used to adjust the current pulse rise time and current drive voltage.

[0092] After determining the range of changes in the current pulse rise time, the droplet velocity corresponding to each pulse rise time within the range can be tested under the premise of a fixed voltage. The pulse rise time corresponding to the maximum droplet velocity can then be determined as the optimal pulse rise time. For example, if the range of changes in the current pulse rise time is determined to be 5-20µs, the droplet velocity corresponding to each pulse rise time within this range can be tested. The droplet velocities corresponding to pulse rise times of 5µs, 10µs, 15µs, and 20µs are 8.2m / s, 9.5m / s, 9.8m / s, and 9.3m / s, respectively. In this case, the pulse rise time of 15µs corresponding to the maximum droplet velocity of 9.8m / s can be taken as the optimal pulse rise time.

[0093] The pre-established relationship between pulse rise time, droplet velocity, and driving voltage in the velocity model can be:

[0094]

[0095] Where v can be the droplet velocity. v t represents the nozzle coefficient, which is primarily determined by the physical parameters of the piezoelectric materials in the inkjet printer. U represents the driving voltage. rise t represents the pulse rise time. rise，opt This is the optimal pulse rise time.

[0096] For example, when it is determined that the droplet velocity of the ink jet ejected by the inkjet device needs to be adjusted, the target droplet velocity v set by the user based on experience that meets the inkjet rate requirements of the inkjet device can be obtained first. targetSimultaneously, within a pre-set range of changes in the current pulse rise time, the droplet velocity corresponding to each pulse rise time within that range can be tested, and the pulse rise time corresponding to the maximum droplet velocity can be determined as the optimal pulse rise time t. rise，opt Then, the determined target ink droplet velocity v can be determined. target And the optimal pulse rise time t rise，opt Substitute these values ​​into the pre-established correlation between pulse rise time, droplet velocity, and driving voltage in the velocity model, and let the pulse rise time t... rise =t rise，opt This process determines the target driving voltage corresponding to the optimal pulse rise time. Finally, if the target driving voltage corresponding to the optimal pulse rise time is within the pre-set optimal range of driving voltages, ensuring that satellite dots are not generated twice, then the inkjet head is controlled to perform inkjet operation based on the target driving voltage corresponding to the optimal pulse rise time. However, if the target driving voltage corresponding to the optimal pulse rise time is not within the optimal range, the value of the optimal pulse rise time can be successively decreased within the current pulse rise time variation range, and the value can be re-substituted into the pre-established correlation formula between pulse rise time, droplet velocity, and driving voltage in the velocity model to determine the corresponding target driving voltage, until the determined target driving voltage meets the optimal range.

[0097] Based on the above embodiments, this embodiment also proposes an optional embodiment. This optional embodiment can further optimize the control of the ink droplet volume during inkjet operation by adjusting the current pulse hold time based on the volume model in the parameter adjustment model, in addition to the above embodiments, including:

[0098] Obtain the target droplet volume and the target driving voltage output by the velocity model in the parameter adjustment model;

[0099] Based on the pre-established correlation between driving voltage, pulse holding time, and droplet volume in the volume model, the target pulse holding time is determined by the target droplet volume and the target driving voltage.

[0100] The inkjet head is controlled to perform inkjet operation based on the target pulse hold time.

[0101] The target droplet volume can be the desired droplet volume preset by the user. The target drive voltage can be the drive voltage output from the speed model used to control the droplet speed during inkjet printing.

[0102] The pre-established relationship between driving voltage, pulse holding time, and droplet volume in the volume model can be:

[0103]

[0104] Where V is the ink droplet volume. K V t represents the nozzle volume factor, which is primarily determined by the physical parameters of the piezoelectric materials in the inkjet printer. U represents the driving voltage. hold τ is the pulse hold time. τ is the response time of the piezoelectric material.

[0105] For example, when it is determined that the droplet volume needs to be adjusted during inkjet printing, a user-preset target droplet volume can be obtained. Simultaneously, the velocity model in the parameter adjustment model is retrieved to determine the target drive voltage. Then, the target droplet volume and target drive voltage are substituted into the pre-established correlation between drive voltage, pulse hold time, and droplet volume in the volume model to determine the target pulse hold time corresponding to the target droplet volume. Finally, the inkjet head is controlled to perform inkjet printing based on the determined target pulse hold time.

[0109] The control module 32 can be used to control the inkjet head's inkjet operation mode by adjusting the current device parameters based on a set parameter adjustment model when the current ink droplet parameters meet the adjustment conditions.

[0110] The instruction receiving module 33 can be used to return and repeatedly execute the acquisition operation of the current device parameters and the current ink droplet parameters before receiving the inkjet end instruction.

[0111] This embodiment provides an inkjet control device that, upon detecting the start of the inkjet device, acquires the current device parameters and the current droplet parameters of the ejected ink droplets during inkjet operation. When the current droplet parameters meet the adjustment conditions, based on a set parameter adjustment model, it controls the inkjet mode of the inkjet head during inkjet operation by adjusting the current device parameters. This automatically adjusts the current device parameters of the inkjet device, controlling it to perform inkjet operation in a suitable inkjet mode.

[0117] Optionally, the control module 32 may include: a satellite point control unit, a velocity control unit, and a volume control unit;

[0118] The current device parameters may include: current driving voltage, current pulse time parameter, and current droplet temperature; the current pulse time parameter may include: current pulse rise time, current pulse hold time, and current pulse fall time.

[0120] The speed control unit can be used to adjust the current pulse rise time and the current driving voltage based on the speed model in the parameter adjustment model, so as to control the ink droplet speed when the inkjet head performs inkjet operation.

[0121] The volume control unit can be used to adjust the current pulse hold time based on the volume model in the parameter adjustment model, so as to control the ink droplet volume when the inkjet head performs inkjet operation.

[0122] Optionally, the satellite point control unit can be specifically used to determine the pulse fall time adjustment amount and the droplet temperature adjustment amount based on the dynamic adjustment coefficient and the number of satellite points in the satellite point model, so as to control the current pulse fall time and the current droplet temperature;

[0123] The inkjet head is controlled to perform inkjet operation based on the adjusted pulse fall time and adjusted droplet temperature, and the number of adjusted satellite dots is detected.

[0124] If the adjusted number of satellite points is detected to be non-zero, the dynamic adjustment coefficient is adjusted, and based on the adjusted dynamic adjustment coefficient, the operation of adjusting the current pulse descent time and the current droplet temperature is re-executed.

[0125] If the number of satellite points after adjustment is detected to be 0, the operation of adjusting the current pulse descent time and the current droplet temperature is terminated.

[0126] Optionally, the speed control unit can be specifically used to obtain the target ink droplet speed;

[0127] Within the preset range of changes in the current pulse rise time, determine the optimal pulse rise time corresponding to the maximum ink droplet velocity;

[0128] Based on the pre-established correlation between pulse rise time, droplet velocity, and driving voltage in the velocity model, the target driving voltage is determined according to the target droplet velocity and the optimal pulse rise time.

[0129] Determine whether the target driving voltage is within a preset range;

[0130] If so, the optimal pulse rise time is determined as the target pulse rise time, and the inkjet head is controlled to perform inkjet operation based on the target pulse rise time and the target drive voltage.

[0131] If not, the optimal pulse rise time is reduced, and based on the reduced optimal pulse rise time, the operation of determining the target drive voltage is returned to be performed again.

[0132] Optionally, the volume control unit can be specifically used to obtain the target ink droplet volume and the target driving voltage output by the velocity model in the parameter adjustment model;

[0133] Based on the pre-established correlation between driving voltage, pulse holding time, and droplet volume in the volume model, the target pulse holding time is determined by the target droplet volume and the target driving voltage.
