Description

Technical Field

[0002] Inkjet printing technology refers to the technology of spraying ink droplets evenly onto the substrate through the nozzle on the print head. Currently, the common substrates on the market are mostly two-dimensional planes. With the development of technology, some three-dimensional substrates also need to be inkjet printed on their different surfaces.

[0003] Currently, inkjet printing of three-dimensional substrates mostly adopts single-sided printing, that is, the three-dimensional substrate is laid flat on the printing platform, one surface is first inkjet printed, and then the other surface is manually flipped over and printed until the three-dimensional substrate is inkjet printed on all surfaces.

[0004] First, this single-sided printing method requires multiple flipping, which not only has low printing efficiency, but the multiple flipping operations are more likely to cause pollution or damage to the surface of the three-dimensional substrate that has been inkjet printed. Secondly, this manual flipping method has inaccurate factors due to human errors, such as position offset, rotation angle change, etc., which may lead to inaccurate alignment between the two surfaces. Inaccurate alignment will cause the ink layer to not connect, affecting the printing quality. Therefore, the problem of low printing efficiency and poor printing quality caused by the single-sided printing and manual multiple flipping methods used in the prior art needs to be solved urgently.

[0048] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and Examples. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0050] At present, inkjet printing for three-dimensional substrates mostly adopts single-sided printing, where the three-dimensional substrate is laid flat on the printing platform to first inkjet print one surface, and then manually flipped over to print the other surface until the three-dimensional substrate has completed inkjet printing on all surfaces. This single-sided printing method requires multiple flipping, which not only has low printing efficiency, but also makes it easier for multiple flipping operations to cause contamination or damage to the surface of the three-dimensional substrate that has been inkjet printed. In the field of inkjet printing of power batteries, since the power battery is composed of multiple battery cells arranged closely, in order to provide each battery cell with anti-friction, insulation and protection effects for the battery cell, it is necessary to spray ink on the surface of each battery cell and form an ink layer of uniform thickness.

[0051] In order to solve the problem of ink layer contamination or damage on the surface of battery cells due to multiple manual flipping, and to improve printing efficiency, please refer to Figure 1 The embodiment of the present invention provides a method for printing three-dimensional substrates on different surfaces using multiple printing modules, and the method is as follows:

[0052] S1: Obtain printing module parameters and three-dimensional substrate surface information;

[0053] S2: obtaining printing parameters according to the printing module parameters and the surface information of the three-dimensional substrate;

[0054] S3: inkjet at least two surfaces of the three-dimensional substrate according to the printing parameters;

[0055] Among them, the printing module parameters include the number of printing modules and the position of each printing module; the three-dimensional substrate surface information includes the number of surfaces and the surface position; and the printing parameters include the corresponding relationship between the printing module and the three-dimensional substrate surface.

[0056] In this embodiment, each printing module includes at least one nozzle for inkjet. The printing parameters also include the distance between the printing module and the surface of the three-dimensional substrate, the ink output of the printing module, etc. The printing module is used for inkjet printing, and the number and position of the surface that needs inkjet are obtained by determining the number of printing modules and the positional relationship between the printing modules, and the printing module is matched with the surface one by one according to the information of the surface on the three-dimensional substrate, so that one printing module corresponds to one surface, and the positional relationship between the printing modules should correspond to the positional relationship between the surfaces. The above method has the following effects. The first point can improve the printing efficiency: optimize the configuration according to the shape and printing requirements of the three-dimensional substrate, and by reasonably arranging the printing module, multiple surfaces can be printed on a printing platform, reducing the number of flips and printing time, and improving the printing efficiency. The second point can improve the alignment accuracy: the surface information of the three-dimensional substrate gives the number and position of the surface. According to this information, the appropriate printing parameters can be determined, including alignment calibration and adjustment of the position of the printing module, to ensure the accurate alignment of each surface, so as to avoid offset or misalignment during the printing process and improve the printing quality. The third point is to improve the printing quality: by accurately setting the printing parameters, the consistency between multiple surfaces can be ensured. Secondly, by combining multiple printing modules to print multiple surfaces with inkjet and accurately setting the printing parameters, the ink layer transitioning between surfaces can be prevented from having seams, thereby improving the printing quality. The fourth point is to simplify the operation process: by obtaining the printing module parameters and the surface information of the three-dimensional substrate in advance, and determining the printing parameters based on this information, the printing operation process can be simplified. Operators can operate according to the pre-set parameters, reduce the time for debugging and adjustment, reduce the difficulty of operation, and improve printing efficiency. The fifth point is that it can be flexibly applied: the optimized printing parameter settings can better adapt to different types of three-dimensional substrates and printing requirements. By reasonably configuring the printing modules and surfaces, three-dimensional substrates with complex shapes or special requirements can be handled. This can expand the application field of printing technology and meet the needs of more different industries and fields.

[0057] Furthermore, the step of performing inkjet printing on at least two surfaces of the three-dimensional substrate according to the printing parameters includes:

[0058] S31: controlling the first printing module to spray ink on the first surface of the three-dimensional substrate according to the printing parameters;

[0059] S32: Controlling the second printing module to spray ink on the second surface of the three-dimensional substrate according to the printing parameters; wherein the first surface is adjacent to the second surface, and the ink spraying direction of the first printing module intersects with the ink spraying direction of the second printing module.

[0060] Embodiment 1:

[0061] like Figure 2 and Figure 6 In this embodiment, two printing modules with intersecting inkjet directions are set to spray ink on two adjacent surfaces, and the inkjet directions of the two printing modules intersect to form an angle of ≤90°. The printing order of the two printing modules is preferably printed simultaneously. The purpose of this setting is to improve the printing efficiency, and the two surfaces can be printed without turning over. Secondly, by setting the printing parameters, the position of the printing module is accurately adjusted. The simultaneous printing of the two printing modules can make the corners where the surfaces contact each other hang ink well, and there will be no problem of ink layer not being able to dock, thereby improving the printing quality. When the three-dimensional substrate is a battery cell, an electrode is provided on one side of the battery cell, which requires special treatment, so only five surfaces on the battery cell need to be printed. Furthermore, only the first printing module and the second printing module are used, and the printing process is to first spray ink on the two adjacent surfaces, then flip the battery cell, and after flipping, spray ink on the other two adjacent surfaces, and finally flip the battery again. After flipping, only the first printing module or the second printing module is enabled to spray ink on the remaining surface. Until the five surfaces to be printed on the three-dimensional substrate are printed.

[0062] Furthermore, after inkjetting at least two surfaces of the three-dimensional substrate according to the printing parameters, the method further comprises:

[0063] S41: performing a first pre-curing on the first surface and the second surface of the three-dimensional substrate.

[0064] In this embodiment, the first printing module and the second printing module are both equipped with pre-curing lamp beads. When the first surface and the second surface are ink-sprayed, the first surface and the second surface are pre-cured. The purpose of this arrangement is that the ink layer has been preliminarily dried after pre-curing, in preparation for subsequent flipping, and the damage or contamination of the ink layer caused by flipping is reduced. Similarly, after each ink-spraying is completed, the ink-sprayed surface is pre-cured, and when the five surfaces are ink-sprayed and pre-cured, a final curing is performed. Preferably, the final curing operation is performed after each pre-curing; that is, the three-dimensional substrate is firstly final-cured after pre-curing, and the three-dimensional substrate is flipped after the final curing, and then the flipped three-dimensional substrate is ink-sprayed, pre-cured, and finally cured until the five surfaces are ink-sprayed. The purpose of this arrangement is that the ink layer has been dry and firm after pre-curing and final curing before flipping, and the problem of damage to the ink layer caused by flipping is avoided to the greatest extent.

[0065] Furthermore, the step of performing inkjet printing on at least two surfaces of the three-dimensional substrate according to the printing parameters includes:

[0066] S311: controlling the first printing module to spray ink on the first surface of the three-dimensional substrate according to the printing parameters;

[0067] S312: Controlling the second printing module to spray ink on the second surface of the three-dimensional substrate according to the printing parameters; wherein the first surface is adjacent to the second surface, and the ink spraying direction of the first printing module intersects with the ink spraying direction of the second printing module.

[0068] S313: Controlling the third printing module to spray ink on the third surface of the three-dimensional substrate according to the printing parameters, wherein the third surface is adjacent to the first surface and / or the second surface.

[0069] S314: controlling the first printing module to spray ink on the fourth surface of the flipped three-dimensional printing object according to the printing parameters;

[0070] S315: Controlling the second printing module to spray ink on the fifth surface of the flipped three-dimensional substrate according to the printing parameters, wherein the fourth surface and the fifth surface are adjacent to each other.

[0071] Furthermore, after inkjetting at least two surfaces of the three-dimensional substrate according to the printing parameters, the method further comprises:

[0072] S42: performing a second pre-curing on the first surface, the second surface and the third surface of the three-dimensional substrate.

[0073] S43: performing a third pre-curing on the fourth surface and the fifth surface of the three-dimensional substrate.

[0074] Embodiment 2:

[0075] like Figure 3As shown, in this embodiment, the first printing module, the second printing module and the third printing module are first used to spray ink on the three surfaces of the three-dimensional substrate. When the three-dimensional substrate is not turned over, the number of printed surfaces is increased, the number of turns is reduced, and the printing efficiency is improved. The position of the printing module is adjusted by setting the printing parameters, and three printing modules are used to spray ink on the three surfaces. The corners between the surfaces can be well ink-hanging, which prevents the problem of multiple surface ink layers not being able to dock when the single-sided inkjet is sprayed, and improves the printing quality. After the first surface, the second surface and the third surface are ink-sprayed, the three-dimensional substrate is turned over, and the first printing module and the second printing module are used to spray ink on the remaining fourth surface and the fifth surface. The third surface is adjacent to the first surface and / or the second surface. When the third surface is adjacent to the first surface and the second surface, the first surface, the second surface and the third surface are in a mutually perpendicular positional relationship; when the third surface is adjacent to the first surface or the second surface, there is a situation where the second surface is adjacent to the first surface and the third surface, and the third surface is parallel to the first surface, or there is a situation where the third surface is adjacent to the first surface and the second surface, and the first surface is parallel to the second surface.

[0076] Preferably, after the first surface, the second surface and the third surface are all ink-sprayed, the three surfaces are pre-cured, and after the pre-curing, the three-dimensional substrate is turned over to spray ink on the remaining fourth surface and fifth surface, and after the ink-spraying of the fourth surface and the fifth surface is completed, the pre-curing is performed again, and finally the entire three-dimensional substrate is subjected to final curing. After the pre-curing, the ink layer can be initially fixed and dried to prevent contamination or damage to the ink-sprayed surface during the flipping. The final curing can completely fix and dry the ink layer to obtain a finished three-dimensional substrate.

[0077] Preferably, a final curing operation is added before turning over the three-dimensional substrate. Figure 5 , Figure 7 and Fig.10 , preferably, the first printing module is perpendicular to the second printing module, that is, the intersection angle is 90°, the third printing module is parallel to the first printing module, the first surface 1 is parallel to the third surface 3, the second surface 2 is perpendicular to the first surface 1 and the third surface 3 respectively, and the fourth surface 5 is perpendicular to the fifth surface 4. The first printing module, the second printing module and the third printing module are arranged on the first printing platform, and a first final curing area is arranged on one side of the first printing platform. When the three-dimensional substrate is a battery monomer, the inkjet curing process is as follows:

[0078] The first printing platform and the first final curing area are activated, the three-dimensional substrate, i.e., the battery cell, is fixed by being placed on the flip fixture and transported to the first printing platform by the transmission mechanism, and the first printing module, the second printing module, and the third printing module respectively perform the first inkjet corresponding to the first surface 1, the second surface 2, and the third surface 3, and each printing module is provided with a pre-curing lamp bead. After the inkjet is completed, the pre-curing lamp bead directly performs the first pre-curing. After the first pre-curing is completed, the battery cell is moved to the first final curing area by the transmission mechanism, and the first final curing is performed on the first surface 1, the second surface 2, and the third surface 3 after the inkjet is completed; at this time, the first final curing is completed, and the flip fixture is activated to flip the front side of the battery cell to the back side, that is, flip the second surface 2 upward to the fifth surface 4 upward, and then rotate the battery cell clockwise by 90° after flipping, so that the flipped battery cell is as shown in FIG. Figure 8 As shown, at this time, the transmission mechanism transports the flipped and rotated battery cell back to the first printing platform, and the first printing module and the second printing module respectively correspond to the fourth surface 5 and the fifth surface 4 for the second inkjet printing. After the second inkjet is completed, the second pre-curing is performed. After the second pre-curing, the battery cell is moved to the first final curing area for the second final curing. Since the sixth surface 6 is provided with electrodes, special treatment is required. Therefore, after the inkjet printing and curing of the first surface 1, the second surface 2, the third surface 3, the fourth surface 5 and the fifth surface 4 are completed, the inkjet printing process of a battery cell is completed. This setting can simplify the operation process, reduce the operation steps and manual intervention, and improve the simplicity and efficiency of the operation. Secondly, the alignment accuracy can be improved. First, the first printing module, the second printing module and the third printing module are used to perform the first inkjet on the first surface 1, the second surface 2 and the third surface 3. After the three-dimensional substrate is turned over, the first printing module and the second printing module are used to perform the second inkjet on the fourth surface 5 and the fifth surface 4. Both inkjet printings use the printing module on the first printing platform to perform inkjet printing, which can ensure that a high alignment accuracy is maintained, avoid printing deviations due to replacement of printing modules, and improve printing accuracy and consistency. Furthermore, the inkjet printing time can be reduced. The third printing module is set to be closed during the first final curing and the flipping of the flipping fixture. The first printing module and the second printing module are controlled to perform inkjet according to the printing parameters, which can reduce the waiting time in the entire production process, improve production efficiency, and shorten the delivery cycle.

[0079] Preferably, the first printing module and the second printing module are perpendicular to each other, that is, the intersection angle is 90°, and the third printing module is parallel to the first printing module, and can print three surfaces perpendicular to each other on one corner of the three-dimensional substrate. After the three surfaces are ink-sprayed, the three-dimensional substrate is turned over, and then the first printing module and the second printing module are ink-sprayed on the remaining two surfaces. This arrangement can improve the adaptability of the printing module and can be used for more specifications of three-dimensional substrates. In order to further improve the printing efficiency, it is preferred that the first printing module, the second printing module, and the third printing module print the first surface, the second surface, and the third surface simultaneously, and the first printing module and the second printing module also print the fourth surface and the fifth surface simultaneously.

[0080] Furthermore, the step of performing inkjet printing on at least two surfaces of the three-dimensional substrate according to the printing parameters includes:

[0081] S321: controlling the first printing module to spray ink on the first surface of the three-dimensional substrate according to the printing parameters;

[0082] S322: Controlling the second printing module to spray ink on the second surface of the three-dimensional substrate according to the printing parameters; wherein the first surface is adjacent to the second surface, and the ink spraying direction of the first printing module intersects with the ink spraying direction of the second printing module.

[0083] S323: Controlling the third printing module to spray ink on the third surface of the three-dimensional substrate according to the printing parameters, wherein the third surface is adjacent to the first surface and / or the second surface.

[0084] S324: controlling the fourth printing module to spray ink on the fourth surface of the three-dimensional printing object according to the printing parameters;

[0085] S325: Controlling the fifth printing module to spray ink on the fifth surface of the three-dimensional substrate according to the printing parameters, wherein the ink spraying direction of the fourth printing module intersects with the ink spraying direction of the fifth printing module, and the fourth surface is adjacent to the fifth surface.

[0086] Furthermore, after inkjetting at least two surfaces of the three-dimensional substrate according to the printing parameters, the method further comprises:

[0087] S44: performing a second pre-curing on the first surface, the second surface and the third surface of the three-dimensional substrate.

[0088] S45: performing a third pre-curing on the fourth surface and the fifth surface of the three-dimensional substrate.

[0089] Embodiment 3:

[0090] See also Figure 4 In this embodiment, the first printing module, the second printing module and the third printing module are first used to spray ink on the first surface, the second surface and the third surface of the three-dimensional substrate. When the three-dimensional substrate is not turned over, the number of printed surfaces at one time is increased, the number of turning times is reduced, and the printing efficiency is improved. In addition, three printing modules are used to spray ink on the three surfaces. The positions of the printing modules are adjusted by setting printing parameters so that the corners between the back and the surface of the inkjet can be well ink-coated, and the problem of multiple surface ink layers not being able to dock when single-sided inkjet is applied is prevented, thereby improving the printing quality. After the inkjet on the first surface, the second surface and the third surface is completed, the three-dimensional substrate is turned over, and the fourth printing module and the fifth printing module are used to spray ink on the remaining fourth surface and fifth surface.

[0091] Preferably, after the first surface, the second surface and the third surface are all ink-sprayed, the three surfaces are pre-cured, and after the pre-curing, the three-dimensional substrate is turned over to ink-spray the remaining fourth surface and the fifth surface, and after the ink-spraying of the fourth surface and the fifth surface is completed, the pre-curing is performed again, and finally the entire three-dimensional substrate is subjected to a final curing. After the pre-curing, the ink layer can be initially fixed and dried to prevent contamination or damage to the ink-sprayed surface during the flipping. The final curing can completely fix and dry the ink layer to obtain a finished three-dimensional substrate.

[0092] Preferably, a final curing operation is added before turning over the three-dimensional substrate. Figure 5 , Figure 7 , Figure 8 and Fig.10 , preferably, the first printing module is perpendicular to the second printing module, the third printing module is parallel to the first printing module, the fourth printing module is perpendicular to the fifth printing module, the first surface 1 is parallel to the third surface 3, the second surface 2 is perpendicular to the first surface 1 and the third surface 3 respectively, and the fourth surface 5 is perpendicular to the fifth surface 4. The first printing module, the second printing module and the third printing module are arranged on the first printing platform, and a first final curing area is provided on one side of the first printing platform. The fourth printing module and the fifth printing module are arranged on the second printing platform, and a second final curing area is provided on one side of the second printing platform. When the three-dimensional substrate is a battery cell, the inkjet curing process is as follows:

[0093] The first printing platform, the second printing platform, the first final curing area and the second final curing area are activated, the three-dimensional substrate, i.e., the battery cell, is fixed by being placed on the flip fixture and transported to the first printing platform by the transmission mechanism, and the first printing module, the second printing module and the third printing module respectively perform the first inkjet printing corresponding to the first surface 1, the second surface 2 and the third surface 3, each printing module is provided with a pre-curing lamp bead, after the inkjet is completed, the pre-curing lamp bead directly performs the first pre-curing, after the first pre-curing is completed, the battery cell is moved to the first final curing area by the transmission mechanism, and the first final curing is performed on the printed first surface 1, the second surface 2 and the third surface 3; at this time, the first final curing is completed, and the flip fixture is activated to flip the front side of the battery cell to the back side, that is, flip the second surface 2 upward to the fifth surface 4 upward, and then rotate the battery cell clockwise by 90° after flipping, so that the flipped battery cell is as shown in FIG. Figure 8As shown, at this time, the battery cell after flipping and rotating is transported to the second printing platform by the transmission mechanism, and the fourth printing module and the fifth printing module respectively correspond to the fourth surface 5 and the fifth surface 4 for the second inkjet printing. The fourth printing module and the fifth printing module are also provided with pre-curing lamp beads, so the second pre-curing is performed after the second inkjet is completed. After the second pre-curing, the battery cell is moved to the second final curing area for the second final curing. Since the sixth surface 6 is provided with electrodes, special treatment is required. Therefore, after the inkjet and curing of the first surface 1, the second surface 2, the third surface 3, the fourth surface 5 and the fifth surface 4 are completed, the inkjet printing process of one battery cell is completed. The advantage of such a setting is that the printing efficiency is further improved. Since the transmission mechanism transports the battery monomer in one direction through the first printing platform, the first final curing area, the second printing platform, and the second final curing area in sequence, when processing a large number of battery monomers, the first printing platform and the second printing platform can work at the same time, and the first final curing area and the second final curing area also work at the same time, forming an assembly line inkjet printing and curing process, which greatly shortens the time for the battery monomer to be transported back and forth to the first printing platform for inkjet printing, and shortens the printing cycle. Secondly, adding the fourth printing module and the fifth printing module can reduce the frequent use of the first printing module and the second printing module. The loss of the first printing module and the second printing module causes the inkjet effect of the first printing module and the inkjet effect of the second printing module and the third printing module deviates, thereby improving the life of the entire inkjet printing and curing equipment and improving the quality of three-sided simultaneous printing; further, using multiple printing platforms and printing modules during the printing process can disperse risks and failure rates. If a printing module fails, other printing modules can still continue to work and compensate for the failed printing module by setting it, reducing printing interruptions and downtime caused by the failure. Furthermore, the first printing platform and the second printing platform are activated at the same time. Since the printing parameters of the first printing platform and the second printing platform are fixed, the printing quality of the battery cells printed in the same batch can be guaranteed to be uniform.

[0094] Embodiment 4:

[0095] See also Fig. 9 In this embodiment, only one printing platform and one final curing area are started, and the five printing modules are arranged on the same printing platform. Fig.10As shown, four printing modules are controlled according to printing parameters to print the first surface 1, the second surface 2, the third surface 3 and the fifth surface 4 respectively, and the last printing module is controlled according to printing parameters to print the fourth surface 5. After printing, a pre-curing is performed, and after pre-curing, the battery cell is moved to the final curing area for final curing. The purpose of this setting is to complete the inkjet of five surfaces on a printing platform without flipping the three-dimensional substrate, further improve the printing efficiency, and avoid the problem of surface contamination or damage caused by the flipping operation. In this embodiment, the printing parameters need to be set. At this time, in addition to the corresponding relationship between the printing module and the surface, the printing parameters also include the distance between the printing module and the corresponding surface, the inkjet amount, the printing module adjustment distance, etc. By setting appropriate printing parameters, the printing quality is improved.
