Description
Technical Field
[0001] The present invention relates to the technical field of inkjet printing, and in particular to a printing and curing method, device, equipment and storage medium of an inclined nozzle. Background Art
[0002] In the process of inkjet printing, the ink needs to be quickly fixed after being sprayed onto the printing medium to ensure the clarity and durability of the image or text. The curing process is the process of converting the ink from liquid to solid, which is important for preventing the ink from spreading and mixing on the printing medium and increasing the drying speed of the printed product.
[0003] In the early days, ink curing mostly used natural drying methods, that is, relying on air flow and temperature changes to gradually dry the ink. However, this method is time-consuming, inefficient, and easily affected by environmental factors, resulting in unstable printing quality. With the advancement of science and technology, a variety of modern ink curing technologies have emerged. For example, ultraviolet (UV) curing technology uses ultraviolet rays to irradiate ink, triggering a chemical reaction inside it, causing the ink to dry and solidify quickly. This method has the advantages of fast curing speed, high efficiency, and environmental protection, so it has been widely used in the field of inkjet printing.
[0004] With the growth of digital technology and printing demand, the requirements for inkjet printing and curing are getting higher and higher. For example, in order to improve the printing accuracy of the nozzle in a specific direction, the technical means of tilting the nozzle at a certain angle relative to the moving direction of the printing medium can be used. However, in the related technology, the curing method based on the normal installation state of the nozzle is still used, which does not match the goal of higher accuracy and efficiency pursued by the tilted nozzle technology, resulting in problems such as high energy consumption during the curing process, which is difficult to meet the growing and diversified needs of the modern market.

It should be noted that, in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations.

If there is no conflict, the embodiments of the present invention and the various features in the embodiments can be combined with each other, all within the protection scope of the present invention.
[0062] In the process of inkjet printing, the ink needs to be quickly fixed after being sprayed onto the printing medium to ensure the clarity and durability of the image or text. The curing process is the process of converting the ink from liquid to solid, which is important for preventing the ink from spreading and mixing on the printing medium and increasing the drying speed of the printed product.
[0063] With the growth of digital technology and printing demand, the requirements for inkjet printing and curing are getting higher and higher. For example, in order to improve the printing accuracy of the nozzle in a specific direction, the technical means of tilting the nozzle at a certain angle relative to the moving direction of the printing medium can be used. However, in the related art, the curing method based on the normal installation state of the nozzle is still used, which makes it difficult to reconcile the curing range and the actual inkjet range. This does not match the goal of higher accuracy and efficiency pursued by the tilted nozzle technology. Therefore, there are problems such as high energy consumption in the curing process, which is difficult to meet the growing and diversified needs of the modern market.
[0064] Based on this, the embodiments of the present invention provide a printing and curing method, device, electronic device and storage medium of a tilted nozzle, which can adjust the curing range of the curing component according to the inkjet range of the tilted nozzle, set the lamp beads within the curing range to the working state during the curing process, and set the lamp beads outside the curing range to the off state during the curing process. The energy consumption during the printing and curing process of the tilted nozzle can be effectively reduced, and energy-saving and high-efficiency effects can be achieved to meet the growing and diversified needs of the modern market.
[0065] The embodiments of the present application provide a printing and curing method, device, electronic device and storage medium of a tilted nozzle, which are specifically described through the following embodiments.
[0066] Example 1
[0067] See also Figure 1 , Figure 1 is an optional flow chart of a printing and curing method using a tilted nozzle provided in an embodiment of the present invention. Figure 1 The method in the embodiment may include but is not limited to steps S101 to S105. Figure 1 The order of step S101 to step S105 is not specifically limited, and the order of steps can be adjusted or some steps can be reduced or added according to actual needs.
[0068] Step S101, obtaining the tilt angle of the tilted nozzle.
[0069] In some embodiments, the tilt angle is the tilt angle of the tilted nozzle relative to the scanning direction of the printing medium. Specifically, the scanning direction of the tilted nozzle on the printing medium is horizontally from left to right, and even if the tilt angles of different tilted nozzles are different, the scanning direction remains unchanged. It can be understood that the tilt angle can ensure that the basic data of subsequent calculations are correct, and provide a reliable basis for obtaining the inkjet range and the curing range.
[0070] It is understandable that the printing curing method of the tilted nozzle is applied to the curing component, which is an important part of the printing system and is responsible for curing the printed material on the printing medium. Specifically, in a curing lamp including a plurality of lamp beads, the lamp beads can be arranged in one or more rows to provide uniform and sufficient curing energy, which is not limited in this embodiment.
[0071] In some embodiments, the preset tilt angle ranges from 45° to 70°, and the device is installed by rotating clockwise or counterclockwise. Preferably, the preset tilt angle is 60° counterclockwise, which is not limited in this embodiment.
[0072] In some embodiments, it is supported to install the nozzle at different preset tilt angles for different printing tasks to achieve the best printing accuracy, nozzle utilization and printing efficiency. Specifically, obtaining the actual tilt angle of the printing task may include but is not limited to the following steps:
[0073] S110: Determine the rotation angle range of the inkjet nozzle according to the data accuracy of the printing task.
[0074] In some embodiments, different printing tasks have different requirements for the data accuracy of the printed image. For printing tasks with lower data accuracy requirements, the rotation angle range of the inkjet nozzle can be smaller, so as to improve the nozzle utilization and printing efficiency while ensuring the printing accuracy; correspondingly, for printing tasks with higher data accuracy requirements, the rotation angle range of the inkjet nozzle needs to be larger to ensure that the printed image meets the printing accuracy requirements. It is understandable that the rotation angle range can be set by those skilled in the art according to actual needs or obtained by establishing a mapping relationship query, and this embodiment does not limit this.
[0075] S120: Determine an actual tilt angle within the rotation angle range according to a priority parameter of the printing task.
[0076] In some embodiments, the priority parameters of the printing task may include but are not limited to: printing accuracy, printing efficiency and printing error. Specifically, the actual tilt angle is calculated by the following formula:
[0077] M=w1·Precision+w2·Efficiency-w3·Error
[0078] Among them, M is the (optimal) actual tilt angle, Precision is the printing accuracy, Efficiency is the printing efficiency, and Error is the printing error (such as overlapping area deviation and / or step error); w1, w2 and w3 correspond to the weights of each priority parameter, and the value of each weight can be adjusted according to the task requirements, which is not limited in this embodiment.
[0079] Step S102, acquiring a first position of the first inkjet channel and a second position of the second inkjet channel according to the tilt angle.
[0080] In some embodiments, the tilted nozzle includes at least a first inkjet channel and a second inkjet channel, and a first position corresponding to the first inkjet channel and a second position corresponding to the second inkjet channel can be calculated according to the tilt angle. The position information can be expressed in coordinate form to accurately reflect the actual layout of the inkjet channels in a tilted state.
[0081] Step S103, acquiring the ink jetting range of the tilted nozzle on the printing medium according to the first position and the second position.
[0082] In some embodiments, the inkjet range of a tilted nozzle scanning on a printing medium can be obtained based on the first position and the second position. For example, when the first position is at the upper right corner and the second position is at the lower left corner, a quadrilateral inkjet area with the first position and the second position as diagonal vertices can be formed. It can be understood that, referring to Figure 3 As shown, since the tilted nozzle moves from left to right along the scanning direction, it is only necessary to determine the upper and lower boundaries of the target inkjet range, and this embodiment does not impose any limitation on this.
[0083] Step S104, obtaining the curing range of the curing component based on the inkjet range, and using the lamp beads within the curing range as working lamp beads.
[0084] In some embodiments, the curing range of the curing component is further determined according to the inkjet range. When the inkjet range of the inclined nozzle is smaller than that of the normal nozzle, the curing range will be smaller corresponding to the inkjet range. When the inkjet range of the inclined nozzle is larger than that of the normal nozzle, the curing range will be larger corresponding to the inkjet range. Then, the lamp beads within the curing range are used as working lamp beads. The working lamp beads are in a working state during the curing process, while the lamp beads in the non-curing range remain in a closed state. By accurately controlling the range of the working lamp beads, energy consumption can be significantly reduced while ensuring the consistency and stability of the curing effect.
[0085] Step S105, controlling the curing assembly to move in the scanning direction, and controlling the working lamp beads to perform light curing on the ink on the printing medium.
[0086] In some embodiments, reference Figure 3 As shown, the curing assembly is installed behind the inclined nozzle. When the inclined nozzle moves from left to right along the scanning direction at an inclined angle, the curing assembly also moves synchronously. During this process, the working lamp beads will continue to irradiate the ink on the printing medium, triggering a UV curing reaction, so that the ink will quickly dry and fix. In order to ensure the quality of curing, the moving speed of the curing assembly should match the printing speed of the nozzle. At the same time, the light intensity and time of the working lamp beads can also be appropriately adjusted according to the specific ink type and printing requirements. If the curing assembly includes multiple columns of lamp beads, the light intensity of each column of lamp beads can also be dynamically adjusted according to the inclination angle of the nozzle and the inkjet distribution to achieve the best curing effect. It can be understood that those skilled in the art can set it according to actual needs, and this embodiment does not limit this.
[0087] Reference Figure 2 As shown, in some embodiments of the present application, before the above step S101: obtaining the tilt angle of the tilted nozzle, it may also include but not be limited to the following steps S201 to S202.
[0088] Step S201, taking the lower left corner of the initial position of the tilted nozzle as the origin and taking the scanning direction as the positive direction of the X-axis to establish a plane rectangular coordinate system.
[0089] In some embodiments, the initial position refers to the position of the nozzle when it is normally installed, and the lower left corner of the initial position of the tilted nozzle is used as the origin, and the scanning direction is used as the positive direction of the X-axis to establish a plane rectangular coordinate system. Specifically, in the initial position, each inkjet channel in the nozzle is arranged front and back from left to right in the scanning direction, and the arrangement direction of a column of nozzles in the inkjet channel is the nozzle column direction, and the nozzle column direction is the same as the Y-axis direction of the plane rectangular coordinate system. It can be understood that each inkjet channel includes at least one column of nozzles.
[0090] Step S202: rotating the tilted nozzle at an angle at the origin with an axis perpendicular to both the scanning direction and the nozzle array direction as the rotation axis.
[0091] In some embodiments, an axis perpendicular to both the scanning direction and the nozzle array direction is selected as the rotation axis. Figure 3 As shown, the tilted nozzle is rotated at an angle θ at the origin with the rotation axis as the center, and the tilted nozzle is in a tilted position. It can be understood that in the tilted position, each inkjet channel in the tilted nozzle is arranged front and back from bottom to top at an inclined angle, for example, the first inkjet channel A is above the second inkjet channel B, and the direction of the nozzle column is also tilted accordingly as the inkjet nozzle rotates.
[0092] Reference Figure 4As shown, in some embodiments of the present application, the above step S102: obtaining the first position of the first inkjet channel and the second position of the second inkjet channel according to the tilt angle may also include but not limited to the following steps S301 to S304.
[0093] Step S301, obtaining a first initial position of a first inkjet channel when the first inkjet channel is at an initial position.
[0094] In some embodiments, the first initial position of the first inkjet channel at the initial position is obtained, and the first initial position can be recorded as (x1, y1). Figure 3 As shown, when the tilted nozzle is installed at a counterclockwise tilt angle θ, the first initial position is the coordinate position of the first nozzle a in the first inkjet channel A at the initial position.
[0095] Step S302, performing calculation according to the tilt angle and the first initial position to obtain a first position.
[0096] In some embodiments, the first position corresponding to the first nozzle a in the first inkjet channel A after the tilted nozzle head is installed tilted can be calculated based on the tilt angle θ and the first initial position (x1, y1), and the first position can be recorded as (x1', y1'). Where: x1' = x1·cos(θ)-y1·sin(θ), y1' = x1·sin(θ)+y1·cos(θ).
[0097] Step S303, obtaining a second initial position of the second inkjet channel when it is at the initial position.
[0098] In some embodiments, the second initial position of the second inkjet channel when it is at the initial position is obtained, and the second initial position can be recorded as (x2, y2). Figure 3 As shown, when the tilted nozzle is installed at a counterclockwise tilt angle θ, the second initial position is the coordinate position of the last nozzle b in the second inkjet channel B at the initial position.
[0099] Step S304, performing calculation according to the tilt angle and the second initial position to obtain a second position.
[0100] In some embodiments, the second position corresponding to the last nozzle b in the second inkjet channel B after the tilted nozzle is installed can be calculated based on the tilt angle θ and the second initial position (x2, y2), and the second position can be recorded as (x2', y2'). Where: x2' = x2·cos(θ)-y2·sin(θ), y2' = x2·sin(θ)+y2·cos(θ).
[0101] In some embodiments, the tilted nozzle can also be installed at a clockwise tilt angle θ, and correspondingly, the first initial position is the coordinate position of the first nozzle b' in the second inkjet channel B when it is in the initial position, and the second initial position is the coordinate position of the last nozzle a' in the first inkjet channel A when it is in the initial position. It can be understood that those skilled in the art can set the first initial position and the second initial position according to actual needs, and only need to ensure that the maximum range point in a scanning process of the tilted nozzle is obtained, and this embodiment does not limit this.
[0102] In some embodiments of the present application, the curing lamp includes at least one column of lamp beads, and the inkjet range of the tilted nozzle is obtained according to the ordinate of the first position and the ordinate of the second position. Specifically, the range between the ordinate of the first position and the ordinate of the second position is directly used as the inkjet range, that is, y1' to y2', so that the lamp beads in the curing lamp whose ordinates are in the range of y1' to y2' are used as working lamp beads.
[0103] In summary, accurate nozzle position information provides a basis for setting the working range of the subsequent curing component, ensuring that the curing component can cover all effective inkjet areas and improve curing efficiency. In addition, this method is suitable for different tilt angles and nozzle designs, has good versatility and adaptability, and can meet diverse printing needs.
[0104] Reference Figure 5 As shown, in some embodiments of the present application, the printing and curing method of the inclined nozzle may also include but is not limited to the following steps S401 to S403.
[0105] Step S401 : calculating the overlapping area of the first inkjet channel and the second inkjet channel in the scanning direction according to the tilt angle.
[0106] In some embodiments, the overlapping area between different inkjet channels in the scanning direction can be calculated according to the tilt angle. Figure 6 As shown, since the nozzle is installed at an angle, the projections A' and B' of the first inkjet channel A and the second inkjet channel B in the scanning direction do not completely overlap, but have a drop to form a certain overlapping area.
[0107] Step S402: Acquire a first light power of an overlapping area and a second light power of a non-overlapping area.
[0108] In some embodiments, a first illumination power of the overlapping area and a second illumination power of the non-overlapping area are obtained, and the first illumination power is greater than the second illumination power. Illumination power refers to the energy density per unit area of the light emitted by the working lamp beads on the printing medium, which determines the curing speed and curing quality of the ink.
[0109] It can be understood that for the overlapping area, since different inkjet channels in this area will spray ink, the amount of ink in the overlapping area is larger, and a higher light power is required to ensure sufficient curing; for the non-overlapping area, that is, the part of the inkjet channel except the overlapping area, a lower light power can be used. Assume that the first light power is P1 and the second light power is P2. The values of P1 and P2 can be adjusted according to the specific ink type and printing requirements. P1 is greater than P2 to ensure that the ink in the overlapping area can be cured quickly to avoid quality problems caused by insufficient curing. Although P2 is less than P1, it is still sufficient to ensure that the ink in the non-overlapping area can be completely cured. Lower light power helps to reduce energy consumption and improve curing efficiency.
[0110] Step S403, controlling the working lamp beads to light-cure the ink on the printing medium according to the first light power and the second light power.
[0111] In some embodiments, the working lamp beads are controlled to light-cure the ink on the printing medium according to the first light power and the second light power. Furthermore, the light intensity, light time or light mode of the working lamp beads can be adjusted according to the light requirements of the overlapping area and the non-overlapping area to ensure that the ink in the entire printing area can be properly cured, which is not limited in this embodiment.
[0112] Therefore, the lighting requirements of the overlapping area and the non-overlapping area can be calculated according to the tilt angle of the tilted nozzle and the position of the inkjet channel, and the light curing process of the working lamp beads can be controlled according to these requirements. This not only improves the accuracy and controllability of the printing curing process, but also ensures the uniform curing of the ink in the printing area and the high-quality printing effect, which helps to reduce energy consumption and production costs, and improve overall production efficiency and economic benefits.
[0113] Reference Figure 7 As shown, in some embodiments of the present application, the inkjet channel includes at least one column of nozzles, and the above step S401: calculating the overlapping area of the first inkjet channel and the second inkjet channel in the scanning direction according to the inclination angle may also include but is not limited to the following steps S501 to S503.
[0114] Step S501, obtaining a distance parameter between the first inkjet channel and the second inkjet channel.
[0115] In some embodiments, a distance parameter between a first inkjet channel and a second inkjet channel is obtained. For a nozzle including multiple inkjet channels, a distance parameter between two adjacent inkjet channels is obtained. Specifically, the distance parameter is the shortest straight-line distance between two adjacent inkjet channels. It is understood that the distance parameters between the various inkjet channels are the same, that is, the inkjet channels in the inkjet nozzle are set to be spaced at the same distance.
[0116] Step S502, obtaining the total length parameter of a column of nozzles in the inkjet channel.
[0117] In some embodiments, a total length parameter of a row of nozzles in an inkjet channel is obtained. Specifically, the total length parameter refers to the total length of a row of nozzles in an inkjet channel along the nozzle row direction. For example, when the inkjet channel is composed of 30 nozzles in a row, the total length parameter is the length value of the 30 nozzles.
[0118] Step S503: Calculate according to the distance parameter, the total length parameter and the tilt angle to obtain the overlapping area of the first inkjet channel and the second inkjet channel in the scanning direction.
[0119] In some embodiments, the overlapping area of the first inkjet channel and the second inkjet channel in the scanning direction is obtained by calculation based on the distance parameter, the total length parameter and the preset tilt angle. Figure 8 As shown, the steps may include but are not limited to the following steps S601 to S603.
[0120] Step S601, calculating according to the distance parameter and the tilt angle to obtain the non-overlapping parameter of the first inkjet channel and the second inkjet channel.
[0121] In some embodiments, the non-overlapping parameter of the first inkjet channel and the second inkjet channel can be obtained by calculating based on the distance parameter and the tangent value of the tilt angle. Fig. 9 As shown, the distance parameter L1 is multiplied by the tangent value tanθ of the tilt angle, that is, L1*tanθ, and the product corresponds to the non-overlapping parameter of the first inkjet channel A and the second inkjet channel B. It can be understood that when the second inkjet channel B moves along with the inkjet head in the scanning direction, the non-overlapping parameter indicates the nozzle non-overlapping area of the second inkjet channel B and the first inkjet channel A.
[0122] Step S602: subtract the non-overlapping parameter from the total length parameter to obtain the overlapping parameter of the first inkjet channel and the second inkjet channel.
[0123] In some embodiments, reference Fig. 9 As shown, the first non-overlapping parameter L1*tanθ is subtracted from the total length parameter L2 to obtain the overlapping parameter of the second inkjet channel B and the first inkjet channel A, i.e., L2-L1*tanθ. It can be understood that when the second inkjet channel B moves along with the inkjet head in the scanning direction, the overlapping parameter indicates the nozzle overlap area of the second inkjet channel B and the first inkjet channel A.
[0124] Step S603: acquiring an overlapping area between the first inkjet channel and the second inkjet channel in the scanning direction based on the overlapping parameter.
[0125] In some embodiments, specifically, refer to Fig. 9 As shown, the overlap parameter corresponds to the overlap area of the head of the second inkjet channel B and the overlap area of the tail of the first inkjet channel A. The overlap area of the first inkjet channel and the second inkjet channel in the scanning direction can be obtained through the overlap parameter.
[0126] Therefore, by introducing the distance parameter and the total length parameter, combined with the inclination angle for calculation, the calculation of the overlapping area is ensured to be more accurate, avoiding the curing quality problems caused by inaccurate estimation. At the same time, it provides a reliable basis for the subsequent light power setting, ensuring that each area can be properly cured and improving the printing quality. It is also suitable for different nozzle designs and inclination angles, has good versatility and adaptability, and can meet diverse printing needs.
[0127] Reference Fig.10 As shown, in some embodiments of the present application, the inclined nozzle further includes a third inkjet channel, and the inkjet printing method of the inclined nozzle may further include but is not limited to the following steps S701 to S704.
[0128] Step S701, acquiring a first position of a first inkjet channel and a third position of a third inkjet channel according to an inclination angle.
[0129] In some embodiments, the first position of the first inkjet channel and the third position of the third inkjet channel are obtained according to the tilt angle. Similarly, the initial coordinates of each inkjet channel at the initial position can be determined first, and then a geometric transformation can be performed according to the tilt angle to obtain a new position after tilting. It is understandable that when the tilted nozzle includes multiple inkjet channels, only the two positions of the first inkjet channel and the last inkjet channel need to be obtained, and the positions of each intermediate inkjet channel are located between the two inkjet channels. It is understandable that when the tilted nozzle has only one inkjet channel, the positions of the first nozzle and the last nozzle in the inkjet channel can be obtained accordingly.
[0130] Step S702: acquiring a target inkjet range of the tilted nozzle on the printing medium according to the first position and the third position.
[0131] In some embodiments, after the positions of the first inkjet channel and the third inkjet channel are obtained, the target inkjet range of the tilted nozzle on the printing medium can be determined according to the two positions. Specifically, the upper and lower boundaries of the target inkjet range are determined by the ordinate of the first position and the ordinate of the third position. It can be understood that since the tilted nozzle moves from left to right along the scanning direction, it is only necessary to determine the upper and lower boundaries of the target inkjet range, and this embodiment does not limit this.
[0132] Step S703, obtaining a target curing range of the curing component based on the target inkjet range, and using the lamp beads within the target curing range as target working lamp beads.
[0133] In some embodiments, the target curing range of the curing component is obtained based on the target inkjet range. The target curing range should completely cover the target inkjet range to ensure that all inks sprayed onto the print medium can be fully cured. Assuming that the target inkjet range is y1' to y3', the target curing range should also be y1' to y3'. Then the lamp beads within the target curing range are used as target working lamp beads. The target working lamp beads are in a working state during the curing process, while the lamp beads outside the target curing range remain in a turned-off state. By precisely controlling the range of the target working lamp beads, energy consumption can be significantly reduced while ensuring the consistency and stability of the curing effect.
[0134] Step S704, controlling the curing assembly to move in the scanning direction, and controlling the target working lamp beads to perform light curing on the ink on the printing medium.
[0135] In some embodiments, the curing assembly is installed behind the tilted nozzle. When the tilted nozzle moves along the scanning direction at an inclined angle, the curing assembly also moves synchronously. During this process, the working lamp beads will continue to irradiate the ink on the printing medium, triggering a UV curing reaction, so that the ink will dry and fix quickly. In order to ensure the quality of curing, the moving speed of the curing assembly should match the printing speed of the nozzle. At the same time, the light intensity and time of the working lamp beads can also be appropriately adjusted according to the specific ink type and printing requirements. If the curing assembly includes multiple columns of lamp beads, the light intensity of each column of lamp beads can also be dynamically adjusted according to the tilt angle of the nozzle and the inkjet distribution to achieve the best curing effect. It can be understood that those skilled in the art can set it according to actual needs, and this embodiment does not limit this.
