[0027] Example 1

[0028] Figure 1 This is a flowchart of an inkjet control method provided in the first embodiment of the present invention. This embodiment is applicable to the case of adjusting and controlling the inkjet mode of an inkjet device. The method can be executed by an inkjet control device, which can be implemented in the form of hardware and / or software. The 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 an inkjet device is started, obtaining current device parameters of the inkjet device and current ink droplet parameters of the ejected ink droplets when an inkjet head in the inkjet device is performing an inkjet operation.

[0030] The inkjet device may be an inkjet printer, a dispensing machine, or other device capable of performing inkjet printing operations. Current device parameters may refer to operating parameters of the inkjet device during the current inkjet operation, such as the drive voltage of the inkjet device, pulse timing parameters, and the droplet temperature required to be reached when the inkjet device ejects ink droplets. Current droplet parameters may refer to parameters related to ink droplets ejected by an inkjet head in the inkjet device during the inkjet operation, such as the velocity of the ink droplets during flight, the shape and size of the ink droplets, or the number of satellite points of the ink droplets.

[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 an inkjet operation, the inkjet control device can obtain the current device parameters of the inkjet device by receiving device operating parameters pre-configured in the inkjet device and input by the user. At the same time, the inkjet control device can collect data on the ejected ink droplets through various pre-configured sensors to obtain the current ink 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 a set parameter adjustment model, the ejection mode of the inkjet head during the inkjet operation is controlled by adjusting the current device parameters.

[0033] The adjustment condition can be determined by examining the current ink droplet parameters to determine whether the current inkjet device's inkjet mode meets the expected operating state. The parameter adjustment model can be used to adjust the current device parameters of the inkjet device so that the inkjet device's inkjet mode, when performing inkjet operations based on the adjusted device parameters, meets the expected operating state.

[0034] For example, the inkjet control device can determine whether the current ink droplet parameters meet the adjustment conditions based on preset ink droplet parameters. If the current ink droplet parameters do not match the preset ink droplet parameters, it is determined that the current ink droplet parameters meet the adjustment conditions, which means that the current inkjet device's inkjet mode 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 obtained current device parameters into a set parameter adjustment model to obtain the adjusted device parameters output by the parameter adjustment model, thereby controlling the inkjet device's spray mode during inkjet operation based on the adjusted device parameters.

[0035] S103 , returning to repeatedly execute the acquisition operation of the current device parameters and the current ink drop parameters until an inkjet end instruction is received.

[0036] The inkjet end instruction may be a control instruction indicating that the inkjet device ends the inkjet operation, and is used to control the inkjet control device to end adjusting the inkjet mode of the inkjet device.

[0037] For example, after the inkjet control device adjusts the current device parameters of the inkjet device, it can continue to obtain the adjusted current device parameters of the inkjet device and the current ink droplet parameters of the ink droplets ejected by the adjusted inkjet device, thereby further monitoring whether the adjusted inkjet device can perform inkjet operations according to the expected working state. If the expected working state is still not achieved, the inkjet device can be further adjusted based on the set parameter adjustment model to control the inkjet device's ejection method during inkjet operation.

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

[0039] When the inkjet device completes an inkjet operation, or when the inkjet device is manually controlled to end / pause an inkjet operation, the inkjet device may generate an inkjet end instruction and send the inkjet end instruction to the inkjet control device. The inkjet control device may determine that the inkjet operation of the inkjet device has ended based on receiving the inkjet end instruction, thereby ending the detection and control of the inkjet device.

[0040] The above-mentioned technical solution of this embodiment obtains the current device parameters of the inkjet device and the current ink droplet parameters of the inkjet head in the inkjet device when performing inkjet operation after detecting that the inkjet device is started, and when the current ink droplet parameters meet the adjustment conditions, based on the set parameter adjustment model, controls the spraying mode of the inkjet head when performing inkjet operation by adjusting the current device parameters. It can automatically adjust the current device parameters of the inkjet device and control the inkjet device to perform inkjet operation in a suitable inkjet mode, which solves the problems of manpower waste and low efficiency caused by manual debugging of the inkjet mode of the inkjet device, saves human resources, and improves the efficiency of adjusting the inkjet mode of the inkjet device.

[0041] Based on the above embodiment, this embodiment proposes an optional embodiment, which can further optimize the above embodiment, including:

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

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

[0044] Satellite dots are typically smaller ink droplets separated from the main ink droplet, resulting from breakage and instability during the inkjet process. The current number of satellite dots refers to the number of satellite dots separated from the ink droplets ejected by the inkjet device during inkjet operation. The current droplet velocity refers to the flight speed of the ink droplets ejected by the inkjet device during inkjet operation. The current droplet volume refers to the volume of the ink droplets ejected by the inkjet device during inkjet operation.

[0045] It is understandable that when an inkjet device is performing an inkjet operation, if the flying speed of the ejected ink droplets is slow, the inkjet device's inkjet operation rate will be affected. If the volume of the ejected ink droplets is large or small, the amount of ink printed on the print medium will be greater or less, thereby affecting the printing effect of the inkjet-printed pattern. If there are satellite dots separated from the ejected ink droplets, the inkjet-printed image will be blurred, have color deviations, or lose details, thereby affecting the quality of the inkjet-printed image. Therefore, it is possible to determine whether the current droplet velocity, current droplet volume, and current number of satellite dots of the inkjet device during the inkjet operation meet the adjustment conditions to determine whether the ejection method of the inkjet device during the inkjet operation needs to be adjusted.

[0046] For example, if the current number of satellite points is greater than 0, then the inkjet method of the current inkjet device is determined to affect the quality of the inkjet-printed image, and the inkjet method of the current inkjet device needs to be adjusted. Alternatively, if the current ink droplet velocity is less than the target velocity, then the inkjet rate of the current inkjet device is determined to be low, and the inkjet method of the current inkjet device needs to be adjusted. Alternatively, if the current ink droplet volume is not equal to the target volume, then the inkjet method of the current inkjet device is determined to affect the printing effect of the inkjet-printed pattern, and the inkjet method of the current inkjet device needs to be adjusted.

[0047] Based on the above embodiment, this embodiment also proposes an optional embodiment, which can further optimize the above embodiment, including:

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

[0049] receiving the current device parameters sent by the inkjet device based on the communication connection with the inkjet device;

[0050] While controlling the inkjet head to perform inkjet operation based on the same frequency controller, controlling the point light source and the CCD camera to capture the target image of the inkjet device during the inkjet operation; the target image includes a continuous imaging image of the ink droplets in flight;

[0051] Performing image analysis on the target image to obtain the current ink droplet parameters.

[0052] The frequency synchronization 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 can be used to capture the target image 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 in flight.

[0053] Exemplarily, when an inkjet device performs an inkjet operation using device operating parameters pre-set by the user or adjusted by an inkjet control device, the inkjet device itself stores the current device parameters for the current inkjet operation. The inkjet control device can, based on a communication connection with the inkjet device, receive the current device parameters sent by the inkjet device to automatically acquire the current device parameters. Furthermore, the inkjet control device can simultaneously control the inkjet head to perform the inkjet operation using a frequency synchronization controller while controlling a point light source and a CCD camera to capture a target image of the inkjet device during the inkjet operation. This ensures that the inkjet operation and the target image capture operation occur at the same frequency, enabling high-precision capture of transient images of high-speed ink droplets through visual inspection methods, resulting in continuous imaging of the ink droplets during flight. Furthermore, based on the continuous imaging of the ink droplets during flight, the shape, size, or number of satellite points of the ink droplets can be determined using an image algorithm, the velocity of the ink droplets can be calculated based on the position changes of the ink droplets in the continuous imaging images, or various other parameters of the ink droplets can be determined using other image analysis methods.

[0054] It is understandable that obtaining the current device parameters of the inkjet device by receiving user-input device operating parameters pre-configured in the inkjet device requires the user to input the current device parameters. Furthermore, after adjusting the inkjet device's inkjet method, the user must confirm the adjusted device parameters and re-enter them into the inkjet device, resulting in poor flexibility and efficiency in obtaining the current device parameters. Furthermore, using various pre-set sensors to collect data on ejected ink droplets to obtain the current droplet parameters of the inkjet device's inkjet head in real time requires multiple types of sensors to collect a large number of droplet parameters, resulting in high costs. Furthermore, the sensor data collection accuracy is poor for ink droplets ejected at high speeds by the ejection head.

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

[0056] Example 2

[0057] Figure 2This is a flowchart of an inkjet control method provided in the second embodiment of the present invention. This embodiment is further optimized on the basis of the above embodiment, including: the current device parameters include: the current driving voltage, the current pulse time parameters and the current ink drop temperature; the current pulse time parameters include: the current pulse rise time, the current pulse hold time and the current pulse fall time. At the same time, this embodiment further refines the parameter adjustment model based on the settings on the basis of the above embodiment, and controls the specific implementation of the ejection method of the inkjet head during the inkjet operation by regulating the current device parameters. Figure 2 As shown, the method includes:

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

[0059] It should be noted that the current driving voltage may refer to the driving voltage used when the current inkjet device performs inkjet operation. The current ink droplet temperature may refer to the ink droplet temperature that the current inkjet device needs to reach when performing inkjet operation. The current pulse time parameter may refer to the time period during which the driving voltage changes from the starting value to the ending value, wherein the current pulse time parameter may also include the current pulse rise time, the current pulse hold time, and the current pulse fall time. The current pulse rise time may be the time period during which the driving voltage changes from low to high, the current pulse hold time may be the time period during which the driving voltage remains stable, and the current pulse fall time may be the time period during which the driving voltage changes from high to low.

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

[0061] The satellite point model in the parameter adjustment model can be used to control the number of satellite points of an ink droplet, forcing it to zero. It should be noted that in the field of inkjet printing, satellite points significantly impact the quality of the inkjet printed pattern. Therefore, this embodiment prioritizes using the satellite point model in the parameter adjustment model to forcibly return the number of satellite points to zero when the current ink droplet parameters meet the adjustment conditions. Once the number of satellite points is ensured to be zero, other parameters of the ink droplets ejected by the inkjet device are then adjusted.

[0062] It should be further noted that the current pulse fall time can affect the breakup speed of the ink tail column during inkjet operation, thereby affecting the number of satellite dots. For example, as the current pulse fall time increases, the breakup speed slows down, the breakup time increases, and the stability increases, which in turn reduces the number of satellite dots. Furthermore, the ink droplet temperature can affect the viscosity of the ink droplet, thereby affecting the number of satellite dots. For example, when the ink droplet temperature increases, the imbalance between the surface tension and viscosity of the ink droplet decreases, which in turn reduces the number of satellite dots. Therefore, the number of satellite dots can be controlled by adjusting the current pulse fall time and ink droplet temperature of the inkjet device.

[0063] Exemplarily, when the current ink droplet parameters meet the adjustment conditions, the number of satellite points in the current ink 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 ink droplet temperature of the inkjet device through the number of satellite points of the ink droplets ejected when the current inkjet device performs an inkjet operation, thereby regulating the current pulse fall time and the current ink droplet temperature of the inkjet device so that when the inkjet device performs an inkjet operation based on the adjusted pulse fall time and the adjusted ink droplet temperature, the number of satellite points of the ink droplets ejected is zero.

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

[0065] The velocity model in the parameter adjustment model can be used to control the flying velocity of ink droplets ejected by the inkjet device during inkjet operation.

[0066] It should be noted that the current driving voltage of the inkjet device determines the deformation of the piezoelectric element, which directly affects the ejection pressure of the inkjet head. The greater the ejection pressure, the faster the ink droplet's flight speed. However, the driving voltage of the inkjet device is not necessarily the higher the better. If the driving voltage is in the high voltage zone, the ink droplets ejected by the inkjet device will split violently, generating secondary satellite points. If the driving voltage is in the low voltage zone, the ejection pressure of the inkjet head is small, and the flight speed of the ink droplets is slow, affecting the inkjet printing rate. Therefore, the value of the driving voltage should be kept within the optimal voltage range pre-set by the technician. In addition, the pulse rise time of the inkjet device will affect the initial acceleration of the ink droplet during flight, thereby affecting the flight speed of the ink droplet. Therefore, the current driving voltage and the current pulse rise time of the inkjet device can be adjusted to control the ink droplet speed during the inkjet head's inkjet operation.

[0067] For example, the current pulse rise time and current driving voltage of the inkjet device can be input into the velocity model in the parameter adjustment model. The velocity model in the parameter adjustment model can determine the optimal pulse rise time and target driving voltage for the inkjet device based on a target ink droplet velocity that meets the rate requirements of the inkjet device, and regulate the current pulse rise time and current driving voltage of the inkjet device based on the optimal pulse rise time and target driving voltage, thereby controlling the ink droplet velocity when the inkjet head performs an inkjet operation.

[0068] S204 : regulating the current pulse holding time based on the volume model in the parameter adjustment model to control the volume of ink droplets when the inkjet head performs an inkjet operation.

[0069] The volume model in the parameter adjustment model can be used to control the volume of ink droplets ejected by the inkjet device during inkjet operation.

[0070] It should be noted that, assuming the inkjet device's hardware remains unchanged, the current pulse hold time of the inkjet device will affect the sustained thrust during inkjet ejection, thereby affecting the volume. For example, the longer the current pulse hold time, the longer the sustained thrust during inkjet ejection, and the larger the volume of the ejected ink droplets. Therefore, by adjusting the current pulse hold time of the inkjet device, the volume of the ink droplets ejected by the inkjet device during inkjet operation can be controlled.

[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 drop volume that meets the effect requirements of the inkjet printing pattern, and adjust the current pulse hold time of the inkjet device based on the optimal pulse hold time, thereby controlling the volume of ink drops when the inkjet head performs an inkjet operation.

[0072] S205 , returning to repeatedly execute the acquisition operation of the current device parameters and the current ink drop parameters until an inkjet end instruction is received.

[0073] The above-mentioned technical scheme of the embodiment of the present invention controls the number of satellite points when the inkjet head performs inkjet operation by regulating the current pulse fall time and the current ink droplet temperature based on the satellite point model in the parameter adjustment model, controls the current pulse rise time and the current driving voltage based on the speed model in the parameter adjustment model to control the ink droplet speed when the inkjet head performs inkjet operation, and controls the current pulse holding time based on the volume model in the parameter adjustment model to control the ink droplet volume when the inkjet head performs inkjet operation, thereby realizing automatic adjustment of the ink droplet speed, ink droplet volume and satellite point number of the ink droplets when the inkjet device performs inkjet operation, saving human resources, improving the efficiency of adjusting the ink droplet speed, ink droplet volume and satellite point number of the inkjet device, and ensuring the inkjet rate of the inkjet device and the quality and effect of the inkjet results.

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

[0075] Determining a pulse fall time adjustment amount and an ink drop temperature adjustment amount based on a dynamic adjustment coefficient in the satellite point model and the current number of satellite points, so as to control the current pulse fall time and the current ink drop temperature;

[0076] Controlling the inkjet head to perform inkjet operation based on the regulated pulse fall time and the regulated ink drop temperature, and detecting the regulated number of satellite dots;

[0077] If it is detected that the adjusted number of satellite points is not 0, the dynamic adjustment coefficient is adjusted, and based on the adjusted dynamic adjustment coefficient, the operation of adjusting the current pulse fall time and the current ink drop temperature is returned to be executed;

[0078] If it is detected that the number of satellite points after adjustment is 0, the operation of adjusting the current pulse fall time and the current ink drop temperature is terminated.

[0079] The dynamic adjustment coefficient may be an adjustment coefficient obtained after training the satellite point model or pre-calibrated, and is used to calculate the pulse fall time adjustment amount and the ink drop temperature adjustment amount of the inkjet device.

[0080] For example, the number of satellite points of the ink droplets ejected by the inkjet device can be input into the satellite point model. The satellite point model can determine the pulse fall time adjustment amount by the dynamic adjustment coefficient in the satellite point model and the input number of satellite points. For example, by Δt fall=α*S*t to calculate the pulse fall time adjustment, where Δt fall is the pulse fall time adjustment amount, α is the dynamic adjustment coefficient, S is the number of input satellite points, and t is the current pulse fall time of the inkjet device.

[0081] Furthermore, the satellite point model can also determine the ink drop temperature adjustment amount by inputting the number of satellite points and the predetermined increase in ink drop temperature for each decrease in the number of satellite points. To calculate the ink drop temperature adjustment amount, where ΔT is the ink drop temperature adjustment amount, The ink drop temperature is the predetermined amount to be increased each time the number of satellite dots is reduced, and S is the input number of satellite dots.

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

[0083] If it is detected that the adjusted number of satellite points is not 0, it means that the pulse fall time adjustment amount and the ink drop temperature adjustment amount are small. The dynamic adjustment coefficient can be increased, and the pulse fall time adjustment amount can be recalculated based on the adjusted dynamic adjustment coefficient, and the ink drop temperature adjustment amount can be recalculated based on the adjusted number of satellite points to enhance the parameter adjustment of the inkjet device, and return to the operation of adjusting the current pulse fall time and the current ink drop temperature until the adjusted number of satellite points is 0.

[0084] Based on the above embodiment, this embodiment further proposes an optional embodiment. This optional embodiment can further optimize the ink droplet velocity when the inkjet head performs an inkjet operation by regulating the current pulse rise time and the current driving voltage based on the velocity model in the parameter adjustment model based on the above embodiment, including:

[0085] Get the target ink drop velocity;

[0086] Determining an optimal pulse rise time corresponding to a maximum ink droplet velocity within a preset change interval of the current pulse rise time;

[0087] Based on the pre-established correlation between the pulse rise time, the ink droplet velocity, and the driving voltage in the velocity model, determining a target driving voltage according to the target ink droplet velocity and the optimal pulse rise time;

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

[0089] If yes, determining the optimal pulse rise time as a target pulse rise time, and controlling the inkjet head to perform inkjet operation based on the target pulse rise time and the target driving 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 driving voltage is returned to be executed again.

[0091] The target droplet velocity can refer to an ink droplet velocity set by the user based on experience to meet the inkjet device's inkjet ejection rate requirements. The current pulse rise time change interval can be a pulse rise time adjustment range determined with the inkjet device's current pulse rise time as the middle value of the interval. The preset range can be an optimal range of drive voltages set by the user to avoid affecting the secondary generation of satellite dots. The target pulse rise time and target drive voltage can be used to control the current pulse rise time and current drive voltage.

[0092] After determining the change interval of the current pulse rise time, the ink droplet velocities corresponding to each pulse rise time within the change interval of the current pulse rise time can be tested under the premise of a fixed voltage, and the pulse rise time corresponding to the maximum ink droplet velocity can be determined as the optimal pulse rise time. For example, the time period of the current pulse rise time change interval is determined to be 5-20us, and the ink droplet velocities corresponding to each pulse rise time are tested within the test interval of the current pulse rise time. It can be obtained that the corresponding ink droplet velocities of pulse rise times of 5us, 10us, 15us and 20us are 8.2m / s, 9.5m / s, 9.8m / s and 9.3m / s respectively. At this time, the pulse rise time of 15us corresponding to the maximum ink droplet velocity of 9.8m / s can be used as the optimal pulse rise time.

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

[0095] Where v is the ink droplet velocity. v is the nozzle coefficient, which is mainly determined by the physical parameters of the piezoelectric material of the inkjet device. U is the driving voltage. rise is the pulse rise time. rise，opt is the optimal pulse rise time.

[0096] For example, when it is determined that the ink droplet velocity of the ink droplets ejected by the inkjet device needs to be adjusted, the target ink droplet velocity v set by the user based on experience and capable of meeting the inkjet rate requirement of the inkjet device can be obtained first. targetAt the same time, within the preset change interval of the current pulse rise time, the ink droplet speeds corresponding to each pulse rise time within the change interval of the current pulse rise time can be tested respectively, and the pulse rise time corresponding to the maximum ink droplet speed can be determined as the optimal pulse rise time t rise，opt Then, the determined target droplet velocity v target And the optimal pulse rise time t rise，opt Substitute the pre-established relationship between pulse rise time, ink droplet velocity and driving voltage in the velocity model, and let the pulse rise time t rise =t rise，opt , thereby determining 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 preset optimal range of the driving voltage, it can be ensured that satellite points will not be generated a second time, and the inkjet head is controlled to perform inkjet operation based on the target driving voltage corresponding to the optimal pulse rise time. 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 reduced in sequence within the current pulse rise time change range, and re-substituted into the correlation relationship between the pulse rise time, ink droplet velocity and driving voltage pre-established 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 embodiment, this embodiment further proposes an optional embodiment. This optional embodiment can further optimize the volume of ink droplets when the inkjet head performs an inkjet operation by regulating the current pulse holding time based on the volume model in the parameter adjustment model based on the above embodiment, including:

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

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

[0100] The inkjet head is controlled to perform an ink ejection operation based on the target pulse holding time.

[0101] The target ink droplet volume may be a desired ink droplet volume preset by a user, and the target driving voltage may be a driving voltage output by a velocity model for controlling the ink droplet velocity when the inkjet head performs an inkjet operation.

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

[0103]

[0104] Where V is the volume of the ink drop. K V is the nozzle volume coefficient, which is mainly determined by the physical parameters of the piezoelectric material of the inkjet device. U is the driving voltage. hold is the pulse holding time. τ is the response time of the piezoelectric material.

[0105] For example, when determining that the droplet volume of an inkjet head during inkjet operation needs to be adjusted, 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. The target droplet volume and target drive voltage are then substituted into the pre-established relationship 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 operations based on the determined target pulse hold time.
