[0044] Before the ink pump control method is described in detail, the hardware structure of an ink pump control system provided by another embodiment of the present invention is described.

[0045] Another embodiment of the present invention provides an ink pump control system, such as Figure 3 As shown, the ink pump control system 50 includes at least one processor 51 and a memory 52 ( Figure 3 A bus connection and a processor are used as an example). A person skilled in the art can understand that Figure 3 The structure shown is only for illustration and does not limit the structure of the electronic device. Figure 3 More or fewer components as shown, or with Figure 3 Different configurations are shown.

[0046] The processor 51 is used to provide computing and control capabilities to control the ink pump control system 50 to perform corresponding tasks, for example, to control the ink pump control system 50 to perform any one of the ink pump control methods provided in the following embodiments of the invention.

Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network and a combination thereof.

[0049] The ink pump control method provided by the embodiment of the present invention is described in detail below. Figure 4 , the method includes but is not limited to the following steps S101-S105:

[0050] S101: Monitor the ink level.

[0051] In this embodiment, the ink level in the ink cartridge is monitored.

[0052] In some embodiments, the ink cartridge includes a main ink cartridge and a sub-ink cartridge, the ink pump includes a first ink pump and a second ink pump, the first ink pump is connected to the main ink cartridge, and the second ink pump is connected to the main ink cartridge and the sub-ink cartridge respectively, and step S101, monitoring the ink level, includes:

[0053] S1011: Monitor the ink levels in the main ink cartridge and the auxiliary ink cartridge respectively.

[0054] Among them, the main ink cartridge is used to provide ink to the nozzle, the auxiliary ink cartridge is used to store the refluxed ink, the first ink pump is connected to the ink barrel and the main ink cartridge, and is used to transport the ink in the ink barrel to the main ink cartridge, and the second ink pump is respectively connected to the main ink cartridge and the auxiliary ink cartridge, and is used to transport the ink in the auxiliary ink cartridge to the main ink cartridge.

[0055] In some embodiments, a liquid level sensor, such as a float type liquid level sensor, is provided in the ink cartridge for real-time monitoring of the ink level.

[0056] In some embodiments, liquid level sensors are respectively provided in the main ink cartridge and the sub-ink cartridge to monitor the ink liquid level conditions in the main ink cartridge and the sub-ink cartridge.

[0057] S102: Determine whether the working conditions are met according to the ink level.

[0058] In this embodiment, whether the ink circuit system needs the ink pump to work is determined according to the ink level. For example, when the ink is insufficient and ink needs to be supplied or when the ink level in the ink cartridge is too high and ink needs to be transferred, the ink pump needs to work to transfer ink.

[0059] In some embodiments, the operating conditions include: the ink level is lower than a low level limit value; and / or the ink level is higher than a high level limit value.

[0060] In some embodiments, step S102, determining whether the working condition is met according to the ink level, includes:

[0061] S1021: Determine whether the first working condition is met based on the ink level in the main ink cartridge.

[0062] S1022: Determine whether the second working condition is met based on the ink level in the auxiliary ink cartridge.

[0063] In some embodiments, the first working condition includes: the ink level of the main ink cartridge is lower than a low liquid level limit value; the second working condition includes: the ink level of the auxiliary ink cartridge is higher than a high liquid level limit value.

[0064] In this embodiment, if the ink level of the main ink cartridge is lower than the low level limit value, that is, the main ink cartridge is out of ink, the first ink pump needs to be started to draw ink from the ink barrel to supply the main ink cartridge. When the ink level of the auxiliary ink cartridge is higher than the high level limit value, that is, there is too much ink in the auxiliary ink cartridge, the second ink pump needs to be started to draw ink from the auxiliary ink cartridge to the main ink cartridge to achieve ink transfer.

[0065] The low liquid level limit value and the high liquid level limit value are liquid level values ​​set in advance. For example, the low liquid level limit value can be set to the liquid level value when the ink in the ink cartridge is about to run out, for example, the low liquid level limit value is set to 20% of the ink cartridge capacity. For example, the high liquid level limit value can be set to the liquid level value when the ink in the ink cartridge is about to overflow, for example, the high liquid level limit value is set to 80% of the ink cartridge capacity.

[0066] In some embodiments, the low liquid level limit value and the high liquid level limit value can be a range, and a liquid level low signal area and a liquid level high signal area are set. When the ink level is in the liquid level low signal area, it is considered that the ink level is lower than the low liquid level limit value and ink needs to be supplied; when the ink level is in the liquid level high signal area, it is considered that the ink level is higher than the high liquid level limit value and ink needs to be transferred. For example, the liquid level low signal area is set to the 0%-25% area of ​​the ink cartridge capacity, and the liquid level high signal area is set to the 75%-100% area of ​​the ink cartridge capacity.

[0067] In this embodiment, when the ink level is lower than the low liquid level limit value, the ink pump needs to work to supply ink, and when the ink level is higher than the high liquid level limit value, the ink pump needs to work to transfer the ink. Therefore, when the ink level is lower than the low liquid level limit value or the ink level is higher than the high liquid level limit value, it is determined that the working conditions are met and the ink pump needs to work.

[0068] In this embodiment, by setting a low liquid level limit value and a high liquid level limit value, it is possible to automatically identify situations where the ink pump needs to work, thereby facilitating more accurate control of the ink pump.

[0069] S103: If the working conditions are met, the ink pump is started at a first rotation speed.

[0070] The first rotation speed is the lowest starting rotation speed. For example, the ink pump is started with a voltage value of the lowest starting voltage of the ink pump, so that the ink pump is started at the lowest starting rotation speed.

[0071] In some embodiments, if the working condition that the ink level is lower than the low liquid level limit value is met, the ink supply pump is started to draw ink from the ink barrel through the ink pump to supply the ink to the ink cartridge; if the working condition that the ink level is higher than the high liquid level limit value is met, the ink extraction pump is started to draw out and transfer the ink in the ink cartridge to reduce the amount of ink in the ink cartridge.

[0072] In some embodiments, in step S103, if the working condition is met, starting the ink pump at the first speed includes:

[0073] S1031: If the first working condition is met, start the first ink pump at a third rotation speed.

[0074] S1032: If the second working condition is met, start the second ink pump at a fourth rotation speed.

[0075] The third rotation speed is the lowest starting rotation speed of the first ink pump, and the fourth rotation speed is the lowest starting rotation speed of the second ink pump.

[0076] In this embodiment, when the ink pump is needed to work, the ink pump is first started at the lowest starting speed, rather than directly starting the ink pump at high power as in the traditional solution. The ink pump is started at a fixed speed to work. Starting the ink pump at the first speed first can reduce sudden impacts on the ink system and try to keep the pressure of the ink system stable.

[0077] S104: Obtain target rotation speed.

[0078] In this embodiment, the speed that the ink pump needs to reach is determined by obtaining the target speed. For example, the target speed can be obtained through testing, and the fluctuation effect of different target speeds on the negative pressure of the overall ink circuit system can be tested to finally select a suitable speed as the target speed. For example, the target speed set by the user can be obtained, such as the speed set by the user through experience.

[0079] In some embodiments, step S104, obtaining the target speed includes:

[0080] S1041: Obtain a first target rotation speed.

[0081] and / or

[0082] S1042: Obtain a second target rotation speed.

[0083] The first target speed is the speed that the first ink pump needs to reach, and the second target speed is the speed that the second ink pump needs to reach. The first target speed and the second target speed may be the same or different.

[0084] In this embodiment, if the first working condition is met, the first ink pump is started, and the first target rotation speed is obtained. If the second working condition is met, the second ink pump is started, and the second target rotation speed is obtained.

[0085] In some embodiments, the target rotation speed is calculated by a preset integration algorithm.

[0086] The preset integral algorithm is a method set in advance for calculating the target speed.

[0087] For example, the target speed can be calculated using an integral curve. For example, the preset integral algorithm can be a trapezoidal speed curve algorithm. The target speed can be calculated by obtaining the system maximum acceleration, the system maximum speed and the expected total time and then using the trapezoidal speed curve algorithm, wherein the system maximum acceleration and the system maximum speed are determined by the physical properties of the ink pump, and the expected total time is the expected time set by the user. For example, the preset integral algorithm can also be an S-shaped speed curve algorithm.

[0088] S105: increasing the speed of the ink pump until the speed of the ink pump reaches the target speed.

[0089] In this embodiment, the speed of the ink pump is controlled to increase, so that the speed of the ink pump increases from a first speed to a target speed, and is maintained at the target speed to operate.

[0090] In some embodiments, step S105, increasing the speed of the ink pump until the speed of the ink pump reaches a target speed includes:

[0091] S1051: Increase the rotation speed of the first ink pump until the rotation speed of the first ink pump reaches a first target rotation speed.

[0092] and / or

[0093] S1052: Increase the rotation speed of the second ink pump until the rotation speed of the second ink pump reaches a second target rotation speed.

[0094] In this embodiment, if the first working condition is met, the first ink pump is started at the lowest starting speed of the first ink pump, and the speed of the first ink pump is increased until the speed of the first ink pump reaches the first target speed.

[0095] If the second working condition is met, the second ink pump is started at the second ink pump's lowest starting speed, and the speed of the second ink pump is increased until the speed of the second ink pump reaches a second target speed.

[0096] In some embodiments, step S105, increasing the speed of the ink pump includes:

[0097] S201: Increase the speed of the ink pump according to the first step value.

[0098] Among them, the first step value is the value set in advance for each speed adjustment. For example, the output power can be controlled by controlling the ink pump voltage. The first step value can be a voltage value. For example, the first step value can be set to 0.1V, and the speed of the ink pump is gradually increased by changing the voltage value by 0.1V each time.

[0099] In some embodiments, the first step value is obtained by testing, and the influence of increasing the speed of the ink pump under different step values ​​on the fluctuation of the negative pressure of the overall ink circuit system is tested, and finally a suitable value is selected as the first step value. In some embodiments, the first step value can also be set by the user based on experience. In some embodiments, the first step value can be automatically set by big data. The specific selection method of the first step value is not limited in the embodiments of the present application.

[0100] In some embodiments, when the ink pump operates at the target rotation speed, an ink supply speed is greater than an ink consumption speed.

[0101] The ink supply speed refers to the speed at which ink enters the ink cartridge, and the consumption speed refers to the speed at which ink flows out of the ink cartridge. In some embodiments, the consumption speed can be calculated through the inkjet data of the nozzle.

[0102] In some embodiments, the speed at which the ink pump draws ink from the ink barrel to supply the main ink cartridge must be greater than the speed at which the main ink cartridge provides ink to the nozzle, so as to prevent the ink in the main ink cartridge from being consumed and air from entering the main ink cartridge, affecting the printing effect.

[0103] In some embodiments, the speed at which the ink pump draws ink from the auxiliary ink cartridge to the main ink cartridge is slower than the speed at which the nozzle delivers ink to the auxiliary ink cartridge, to prevent the situation where air is delivered to the main ink cartridge after the ink in the auxiliary ink cartridge is consumed, thereby affecting the printing effect.

[0104] In this embodiment, the rotation speed of the ink pump gradually increases until it maintains running at the target rotation speed, and then the ink supply speed and the ink consumption speed are detected. If the ink supply speed is lower than the consumption speed, the ink in the ink cartridge may be consumed, causing air to enter the ink cartridge and affecting the printing quality. Therefore, it is necessary to ensure that the ink supply speed is higher than the consumption speed to ensure that the ink left in the ink cartridge will not be completely used up.

[0105] In some embodiments, see Figure 5 , the method further comprises:

[0106] S106: Determine whether the working stop condition is met according to the ink level.

[0107] In this embodiment, the ink pump can be stopped according to the ink level to determine whether it has completed the working target. For example, after the ink supply is completed and there is no longer ink shortage or the ink transfer is completed and the ink level is normal, the ink pump can be controlled to stop working.

[0108] In some embodiments, step S106, determining whether the stop working condition is met according to the ink level includes:

[0109] S1021: Determine whether the first stop working condition is met based on the ink level in the main ink cartridge.

[0110] S1022: Determine whether the second stop working condition is met based on the ink level in the auxiliary ink cartridge.

[0111] In this embodiment, if the first ink pump is working, the ink level in the main ink tank is used to determine whether the first stop working condition is met, so as to determine whether the first ink pump can be stopped. If the second ink pump is working, the ink level in the auxiliary ink tank is used to determine whether the second stop working condition is met, so as to determine whether the second ink pump can be stopped.

[0112] In some embodiments, the stop working condition includes: the ink level increases from below the low level limit value to the normal level value; and / or the ink level decreases from above the high level limit value to the normal level value.

[0113] In some embodiments, the first stop working condition includes: the ink level of the main ink tank increases from below a low level limit value to a normal level value.

[0114] In some embodiments, the second stop working condition includes: the ink level of the auxiliary ink tank decreases from higher than the high level limit value to the normal level value.

[0115] The normal liquid level value is a liquid level value set in advance. For example, the normal liquid level value can be set to a value with a suitable amount of ink in the ink cartridge, such as setting the normal liquid level value to 50% of the ink cartridge capacity. For example, the normal liquid level value can also be a range, such as setting the normal liquid level value to 30%-70% of the ink cartridge capacity, and the ink level is considered normal within this range.

[0116] In this embodiment, if the ink level is lower than the low liquid level limit value, the working condition is met, and the ink pump is started until the ink level rises from below the low liquid level limit value to the normal liquid level value, then the stop working condition is met, and the ink pump can be controlled to stop working; if the ink level is higher than the high liquid level limit value, the working condition is met, and the ink pump is started until the ink level drops from above the high liquid level limit value to the normal liquid level value, then the stop working condition is met, and the ink pump can be controlled to stop working.

[0117] In some embodiments, whether the ink pump can stop working is determined by the ink level in the main ink cartridge and / or the auxiliary ink cartridge. For example, when the ink level in the main ink cartridge rises from below the low level limit value to the normal level value, that is, when the main ink cartridge is no longer short of ink, the stop working condition is met, and the ink pump can be controlled to stop working and stop delivering ink from the ink barrel to the main ink cartridge. For example, when the ink level in the auxiliary ink cartridge is higher than the high level limit value and drops to the normal level value, that is, when there is no more ink in the auxiliary ink cartridge, the stop working condition is met, and the ink pump can be controlled to stop working and stop delivering ink from the auxiliary ink cartridge to the main ink cartridge.

[0118] In this embodiment, by setting the normal liquid level value, it is possible to automatically identify the situation where the ink pump can stop working, so as to facilitate more accurate control of the ink pump.

[0119] S107: If the stop working condition is met, the speed of the ink pump is reduced until the ink pump stops.

[0120] In this embodiment, if the stop working condition is met, the rotation speed of the ink pump is reduced, so that the ink pump running at the target rotation speed gradually reduces the rotation speed until the ink pump stops.

[0121] In some embodiments, in step S107, if the stop working condition is met, reducing the speed of the ink pump until the ink pump stops includes:

[0122] S1071: If the first stopping condition is met, the rotation speed of the first ink pump is reduced until the first ink pump stops.

[0123] S1072: If the second stop working condition is met, the rotation speed of the second ink pump is reduced until the second ink pump stops.

[0124] In this embodiment, if the first stop working condition is met, the rotation speed of the first ink pump is reduced, so that the first ink pump running at the first target rotation speed gradually reduces the rotation speed until the first ink pump stops. If the second stop working condition is met, the rotation speed of the second ink pump is reduced, so that the second ink pump running at the second target rotation speed gradually reduces the rotation speed until the second ink pump stops.

[0125] In some embodiments, in step S107, reducing the speed of the ink pump includes:

[0126] S301: reducing the speed of the ink pump according to the second step value.

[0127] Among them, the second step value is the value set in advance for each speed adjustment. For example, the output power can be controlled by controlling the ink pump voltage. The first step value can be a voltage value. For example, the first step value can be set to 0.1V, and the speed of the ink pump can be gradually reduced by changing the voltage value by 0.1V each time.

[0128] In some embodiments, the first step value is obtained by testing, and the influence of reducing the speed of the ink pump under different step values ​​on the fluctuation of the negative pressure of the overall ink circuit system is tested, and finally a suitable value is selected as the second step value. In some embodiments, the second step value can also be set by the user based on experience. In some embodiments, the second step value can be automatically set by big data. The specific selection method of the second step value is not limited in the embodiments of the present application.

[0129] In some embodiments, in step S107, if the stop working condition is met, reducing the speed of the ink pump until the ink pump stops includes:

[0130] S401: If the stopping condition is met, the speed of the ink pump is reduced after a first period of time until the ink pump stops.

[0131] The first time is a time period set in advance. In some embodiments, the first time is obtained by testing. By testing the effect of reducing the rotation speed of the ink pump under different waiting times on the fluctuation of the negative pressure of the overall ink system, a suitable value is finally selected as the first time.

[0132] In this embodiment, after the stop working condition is met, the ink pump is not immediately controlled to reduce the speed. Instead, the ink pump works for a period of time before the speed is reduced until the ink pump stops. This can improve the stability of the system and reduce the pressure fluctuations caused to the system.

[0133] To summarize, the ink pump control method provided in the embodiment of the present invention monitors the ink liquid level and determines whether the working conditions are met according to the ink liquid level. If the working conditions are met, the ink pump is started at a first speed, wherein the first speed is the minimum starting speed. The target speed is obtained, and the speed of the ink pump is increased until the speed of the ink pump reaches the target speed. When the ink pump is working, the speed of the ink pump can be controlled to reduce the impact of the ink pump on the ink path system and reduce pressure fluctuations, thereby ensuring the inkjet effect and improving the printing quality.
