Description

Technical Field

[0001] This application relates to the field of battery cells, and in particular to a method, apparatus, equipment and medium for printing the edges of a square battery cell. Background Technology

[0002] Inkjet printing technology for square battery cells involves inkjet printing on all six surfaces. Due to inherent limitations in the square cell manufacturing process, each surface's four edges are prone to defects such as protrusions, sharp edges, and burrs. Directly printing the entire surface not only results in poor printing quality in the edge areas but may also affect the overall product performance. To address this issue, multiple compensation prints must be performed on all edges before full-surface printing. However, this process can easily lead to excessive print thickness, exceeding permissible technical specifications, and also reducing the withstand voltage performance of the final insulating layer. Summary of the Invention

[0010] Based on the first printed graphic, control the printing device to perform the first print;

[0011] The printing device is controlled to continue printing until the preset number of prints is completed. Starting from the second print, each print is discretely filled with printable pixels that were not filled after the previous print based on the corresponding preset ink volume.

[0016] A template matching module is used to match a template graphic corresponding to each column of printable pixels in a preset printable graphic template library, using the ink volume of each column of printable pixels in the area to be printed. The printable graphic template library includes multiple template graphics. Each template graphic, the source printable graphic, and the outer contour shape of the area to be printed are identical, and each is set to multiple columns of printable pixels. Multiple template graphics correspond to multiple different template printing ink volumes.

[0017] The graphic generation module is used to determine the first print graphic based on the source print graphic and the template graphic corresponding to each column of printable pixels in the area to be printed;

[0018] The first printing module is used to control the printing device to perform the first printing based on the first printing pattern;

[0019] The second printing module is used to control the printing device to continue printing until the preset number of prints is completed.

[0023] The method, apparatus, device, and medium for printing the edge of a square battery cell according to the embodiments of this application determine the ink amount of each printable pixel in the area to be printed by combining the gradient printing column range and the gradient ink amount range.

This ensures the fit between the printed graphic and the edge contour, reduces the possibility of concentrated ink accumulation by controlling the ink amount of the template printing, and improves the ink dripping effect. Furthermore, subsequent printing cycles are used to discretely fill the previously unfilled pixels, effectively controlling the overall printing thickness and reducing the possibility of the thickness exceeding the allowable technical specifications.

[0037] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this application, not all embodiments.

[0038] like Figure 1 As shown, Figure 1 This is a flowchart of a method for printing the edge of a square battery cell according to an embodiment of this application. The method includes steps S100 to S700.

[0039] Step S100: Obtain the preset number of prints for the area to be printed, and the preset amount of ink required for each print.

[0040] Step S200: Obtain the source printable graphic;

[0041] Step S300: Based on the predetermined gradient printing column range of the area to be printed, the predetermined gradient ink volume range corresponding to the area to be printed, and the preset ink volume required for the first print, determine the ink volume of each printable pixel in the area to be printed.

[0042] Step S400: Using the ink volume of each column of printable pixels in the area to be printed, match the template graphic corresponding to each column of printable pixels in the preset print graphic template library; wherein, the print graphic template library includes multiple template graphics; each template graphic and source print graphic has the same outer contour shape as the area to be printed, and is set to multiple columns of printable pixels; multiple template graphics correspond to multiple different template print ink volumes; each template graphic is obtained by discretely filling multiple columns of printable pixels according to the corresponding template print ink volume, and the template print ink volume is the proportion of the printable pixels filled in each column of printable pixels;

[0043] Step S500: Based on the source print graphic and the template graphic corresponding to each column of printable pixels in the area to be printed, determine the first print graphic;

[0044] Step S600: Based on the first printed graphic, control the printing device to perform the first print;

[0045] Step S700: Control the printing device to continue printing until the preset number of prints is completed. Starting from the second print, each print is based on the corresponding preset ink volume to discretely fill the printable pixels that were not filled after the previous print.

[0046] In this embodiment, by combining the gradient printing column range and the gradient ink volume range to determine the ink volume of each printable pixel in the area to be printed, precise adaptation and compensation for edge defects can be achieved. At the same time, relying on the template graphic library based on discrete filling, the template graphic of each printable pixel in the area to be printed is matched, which not only ensures the fit between the printed graphic and the edge contour, but also reduces the possibility of concentrated ink accumulation through template printing ink volume control, and improves the ink dripping effect. Furthermore, subsequent printing times are used to discretely fill the previously unfilled pixels, effectively controlling the overall printing thickness and reducing the possibility of thickness exceeding the allowable technical specifications. Meanwhile, discrete filling optimizes the uniformity of ink volume distribution and improves the voltage resistance performance of the final insulation layer.

[0047] The above source printable graphic can be understood as having each bit of each column of printable pixels filled, such as... Figure 2 As shown.

[0048] The preset number of prints and the preset ink volume required for each print can be flexibly set according to actual needs. In some implementations, the total ink volume for the preset number of prints is 100% ink volume, but it can also be slightly increased or decreased according to actual needs.

[0049] The aforementioned 100% ink coverage can be understood as filling every single printable pixel in the area to be printed, while the remaining percentages can be understood as filling the corresponding percentage of printable pixels in the area to be printed. Figures 2 to 5 .

[0050] The above area to be printed can be used as a reference. Figure 7 To understand, Figure 7 The image shows the entire surface of one side of a square-shaped battery cell, where the edge portion is the ridge edge. Figure 7 The gray-filled area can be divided into four areas to be printed: upper, lower, left, and right. The square cell edge printing method in this application embodiment can be executed for each area to be printed.

[0051] When the area to be printed is selected from an edge or a similar rectangular region, it can be understood as a two-dimensional matrix composed of multiple columns of printable pixels, such as... Figures 2 to 6 As shown.

[0052] It should be noted that when there is a need for irregularly shaped printing, a two-dimensional matrix may not be used; that is, there is a possibility that the number of pixels in multiple columns to be printed may be different.

[0053] The aforementioned gradient printing column range can be understood as the number of columns in the area to be printed that need to be gradient-transformed. For example, ... Figure 6 As shown, the amount of ink gradually increases from the rightmost column to the leftmost column.

[0054] The aforementioned gradient ink volume range can be understood as the change from the lowest ink volume to the highest ink volume within a column constrained by the gradient printing column range. For example, ... Figure 6 As shown, the ink volume ranges from g% to 100%, where g can be flexibly set according to actual needs, and g is less than 100%.

[0055] The preset ink volume required for the first print is typically less than or equal to 50% to ensure that, during discrete distribution, all filled printable pixels are not directly connected. Figures 3 to 5 The diagram shows the filling percentages of 0%, 30%, and 50%.

[0056] The ink volume for each printable pixel in the aforementioned printable area can be understood as follows: Given a predetermined ink volume for the first print, the total ink consumption is known. Then, using the gradient print column range and gradient ink volume range, the specific number of columns in the gradient printable area and the corresponding ink volume or ink percentage for each column can be determined. This allows for the allocation of ink volume to these columns using the predetermined ink volume for the first print, resulting in the ink volume for each printable pixel. In practice, fixed constraints can be preset. Operators can automatically obtain the ink volume for each printable pixel by inputting the predetermined ink volume for the first print, the gradient print column range, and the gradient ink volume range.

[0057] The multiple template graphics in the aforementioned printable graphic template library can be understood as being similar to... Figure 3 The blank two-dimensional matrix shown is filled with multiple columns of printable pixels with different percentages of ink to obtain the graphic.

[0058] The ink volume for printing the above multiple template graphics can be determined according to actual needs. For example, it can be set from 1% to 100%, with each 1% interval, or with intervals of 0.5%, 2%, etc., or it can be set by yourself, for example, 20%, 40%, 60%, etc.

[0059] The edges of the aforementioned square battery cell can be predetermined, and the source print pattern can be determined based on the printing performance of the printing equipment. In a single printing process, the source print pattern, the area to be printed, and the template pattern can all be set as a two-dimensional matrix of multiple printable pixels.

[0060] Once the ink volume of each printable pixel column is determined, it can be directly matched with the ink volume of the template graphic corresponding to each template graphic. If the ink volume is consistent, the match is successful, without the need for further matching of the specific fill state of the template graphic.

[0061] The multiple columns of printable pixels in each of the above template graphics are filled with discrete randomness to minimize the possibility of ink dots sticking together between the filled printable pixels.

[0062] Once the template graphic corresponding to each column of printable pixels in the area to be printed is determined, and since each template graphic and the source printable graphic have the same outer contour shape as the area to be printed (i.e., they can all be understood as a two-dimensional matrix), the blank two-dimensional matrix can be filled column by column using the template graphic corresponding to each column of printable pixels in the area to be printed, thus obtaining the first printable graphic. This first printable graphic also has the characteristics of being discrete and having gradually changing column directions.

[0063] Specifically, such as Figures 3 to 6 As shown, Figure 4 The template graphic shown is 30% of the preset ink volume. Figure 5 A template graphic with 50% preset ink volume; if you need to obtain... Figure 6 The gradient effect shown needs to be determined. Figure 6 The template graphic corresponding to each column, for example, for Figure 6 If column 'a' requires 30% ink volume, then... Figure 4 Fill the corresponding column a in the middle. Figure 3 Similarly, for column a in the middle, the same applies to column 'a'. Figure 6 If column b requires 50% of the ink volume, then... Figure 4 Fill the corresponding column b to Figure 3 Using the method described in column b, you can fill each column until you get the desired result. Figure 6 Chinese graphic.

[0064] After the first printout of the graphic is completed, you can print sequentially according to the preset number of printouts and the preset ink volume for each printout. It should be noted that in order to reduce the possibility of ink dot overlap, starting from the second printout, select the printable pixels that have not yet been filled with ink dots after the previous printout to fill them. In addition, to make the ink dot distribution more uniform, you can also continue to use a discrete distribution method for discrete printing.

[0065] It should be noted that printing can be stopped after all printable pixels have been printed, or discrete printing can continue as needed to reduce the number of times a single printable pixel is repeatedly filled, thus reducing the thickness.

[0066] In some implementations, the ink amount for each printable pixel in the area to be printed is determined based on a predetermined gradient print column range, a pre-acquired gradient ink amount range corresponding to the area to be printed, and a preset ink amount required for the first print, including:

[0067] Based on the gradient printing column range of the area to be printed and the corresponding gradient ink volume range of the area to be printed, determine the ink volume ratio of each column of printable pixels.

[0068] Based on the ink volume ratio and the preset ink volume required for the first print, determine the ink volume of each column of printable pixels in the area to be printed.

[0069] The gradient printing column range mentioned above can determine the specific area that needs to be gradient printed, such as... Figure 6 As shown, from the rightmost column to the leftmost column, the gradient ink volume range can be understood as a pattern of gradually increasing ink volume from the lowest ink volume corresponding to the rightmost column to the lowest ink volume corresponding to the leftmost column.

[0070] Specifically, the formula for estimating ink volume for each column from the rightmost to the leftmost is as follows:

[0071] ;

[0072] In the formula, Ink_R can be understood as the estimated ink volume corresponding to the Rth column, g% can be understood as the ink volume usage being g percent, and w_g can be understood as the gradient column number corresponding to the gradient printing column range.

[0073] Based on the above formula, the estimated ink volume ratio of each column can be determined, and then the ink volume of each printable pixel position of the column to be printed can be determined based on the preset ink volume required for the first print.

[0074] In some implementations, the ink volume of each printable pixel in the area to be printed is used to match a template graphic corresponding to each printable pixel in a preset printable graphic template library, including:

[0075] The ink volume of each printable pixel in the area to be printed is matched with the ink volume of multiple template graphics, and the template graphics with matching ink volume are used as the corresponding template graphics.

[0076] In this embodiment, the ink volume of the column to be printed is directly matched with the ink volume of each of the multiple template graphics, without the need for additional complex parameter adjustments or intermediate conversion steps. This matching method simplifies the logical process, avoids efficiency losses caused by unnecessary operations, and can quickly identify templates with suitable ink volumes, accurately obtaining the template graphics corresponding to the printable pixels of each column, providing convenient support for the efficient advancement and quality control of subsequent edge printing.

[0077] In some implementations, multiple template graphics are obtained through the following steps:

[0078] Determine the number of template graphics required and the amount of ink to print for each template graphic; the ink amounts for printing multiple template graphics will be different.

[0079] Based on the source print graphic, determine the template fill graphic with the same number as the template graphic. Each template fill graphic has the same outer contour shape as the source print graphic and is set to multiple columns of printable pixels.

[0080] Based on the amount of ink for printing each template graphic, the printable pixels in multiple columns of the corresponding template graphic are randomly filled to obtain the corresponding template graphic.

[0081] The ink volume corresponding to each of the above template graphics is different, which can be understood as obtaining different ink volumes for different templates based on actual needs. Furthermore, each template graphic can be understood as being obtained by randomly filling multiple columns of pixels to be printed using a blank two-dimensional matrix.

[0082] The aforementioned discrete random filling can be implemented based on the weighted random number method. This method distributes discrete random numbers to generate a discrete integer distribution with uniform interval widths, where the probability is the same within each interval. In some implementations, this method can be used to generate 100 templates, or even more, corresponding to 0-100%.

[0083] In this embodiment, different ink volumes for printing templates are determined and corresponding template graphics are generated. This allows for the construction of a template library covering various ink volume requirements, accurately adapting to the gradual ink volume range of the area to be printed, and meeting the needs for edge difference compensation. Simultaneously, the template fill graphic matches the outer contour of the source print graphic, ensuring a high degree of fit between the final generated template graphic and the contour of the area to be printed, preventing printing misalignment due to contour deviations during subsequent printing. Furthermore, discrete random filling based on the template ink volume results in a more uniform filling distribution for each column of printable pixels, preventing ink accumulation, reducing the risk of exceeding thickness limits, optimizing the ink layer structure, and improving the dielectric strength of the insulation layer.

[0084] In some implementations, the first print pattern is determined based on the source print pattern and the template pattern corresponding to each column of printable pixels in the area to be printed, including:

[0085] For each column of printable pixels in the area to be printed, perform a bitwise AND operation with the source printable graphic to obtain the operation column graphic corresponding to each column of printable pixels in the area to be printed.

[0086] Based on multiple operation column graphics, the first print graphic is obtained.

[0087] The printable pixels in each column of the area to be printed have been determined in the template above. Therefore, the operation column graphic corresponding to each column can be obtained by performing a bitwise AND operation between the template graphic and the source print graphic. Alternatively, the graphic corresponding to that column can be directly determined from the template graphic to obtain the operation column graphic.

[0088] Each of the operation column graphics obtained above can correspond to a column of printable pixels in the area to be printed. Thus, multiple operation column graphics can be spliced ​​together based on the column order of multiple columns of printable pixels in the area to be printed to obtain the first printed graphic.

[0089] The above "AND operation" can be understood as follows: a pixel to be printed is "1" if it is filled with ink dots and "0" if it is not filled with ink dots. The source print graphic can be understood as fully filled, that is, all zeros. Therefore, by performing a bitwise AND operation between the template graphic and the source print graphic on the pixels to be printed, we can obtain an operation column graphic that is consistent with the template graphic.

[0090] In this embodiment, the operation column graphics are obtained by performing a bitwise AND operation between the template graphics and the source print graphics. This ensures that each column of graphics not only matches the outline reference of the source print graphics but also incorporates the ink volume control characteristics of the template graphics, reducing the possibility of deviations between the operation column graphics and the outline of the area to be printed or imbalances in ink volume distribution. Simultaneously, the first print graphics are generated by splicing multiple operation column graphics column by column, accurately corresponding to the printable pixels of each column in the area to be printed. This ensures the integrity of the overall graphics and the continuity between columns, effectively reducing the possibility of printing defects caused by splicing misalignment and laying a precise graphic foundation for subsequent discrete printing.

[0091] In some implementations, controlling the printing device to continue printing until a preset number of print runs are completed includes:

[0092] If the current number of prints is less than or equal to the preset number of prints, the printable pixels that were not filled after the previous print are discretely filled according to the preset ink volume corresponding to the current number of prints.

[0093] Printing stops when all printable pixels in each column of the area to be printed are filled.

[0094] In this embodiment, the ink volume is preset according to the current printing count, and only pixels that were not filled in the previous print are discretely filled. This allows for precise control of the ink volume input each time, avoiding ink accumulation caused by repeated filling and effectively preventing the problem of excessive printing thickness. At the same time, discrete filling ensures uniform ink distribution, helping to improve the voltage resistance performance of the insulation layer. The setting to stop printing after all pixels in a column are filled avoids invalid printing operations, improving printing efficiency and ensuring that edge defects in each column are fully compensated, further ensuring the stability of edge printing quality.

[0095] In some implementations, controlling the printing device to continue printing until a preset number of print runs are completed includes:

[0096] If the current number of prints is less than or equal to the preset number of prints, the printable pixels that were not filled after the previous print are discretely filled according to the preset ink volume corresponding to the current number of prints.

[0097] In this process, when all the printable pixels in each column of the area to be printed are filled, the already filled printable pixels are then filled discretely.

[0098] In this embodiment, the previously unfilled pixels are discretely filled according to the preset ink volume corresponding to the current printing count. This allows for precise control of the ink volume for each print, preventing ink accumulation and effectively preventing the overall printing thickness from exceeding the limit. Furthermore, after each column of the area to be printed has been filled, the already filled pixels are still discretely filled, which further optimizes the uniformity of ink layer distribution, reduces local thickness differences in the ink layer, and improves the voltage resistance of the final insulating layer.

[0099] The edge printing method for square battery cells provided in this application can be executed by a square battery cell edge printing device. This application uses the square battery cell edge printing device executing the edge printing method as an example to illustrate the square battery cell edge printing device provided in this application.

[0102] The original graphic acquisition module is used to acquire the source print graphic;

[0103] The single-column ink volume determination module is used to determine the printable column ink volume of each column of printable pixels in the printable area based on the pre-determined gradient print column range of the printable area, the pre-acquired gradient ink volume range corresponding to the printable area, and the preset ink volume required for the first print.

[0104] The template matching module is used to match the template graphic corresponding to each column of printable pixels in the pre-set print graphic template library by utilizing the ink volume of each column of printable pixels in the area to be printed. The print graphic template library includes multiple template graphics. Each template graphic and source print graphic has the same outer contour shape as the area to be printed and is set to have multiple columns of printable pixels. Multiple template graphics correspond to multiple different template printing ink volumes. Each template graphic is obtained by discretely filling multiple columns of printable pixels according to the corresponding template printing ink volume. The template printing ink volume is the proportion of printable pixels filled in each column of printable pixels.

[0105] The graphic generation module is used to determine the first print graphic based on the source print graphic and the template graphic corresponding to each column of printable pixels in the area to be printed;
