[0097] Embodiment 1

[0098] See also Figure 1 , Figure 1 It is a flow chart of a method for printing and curing a battery cell insulating coating disclosed in an embodiment of the present application. Optionally, the method can be implemented by a coating printing and curing device, which can be integrated in a coating printing and curing device, or a local server or cloud server for processing the printing and curing process of the battery cell insulating coating, etc., which is not limited in the embodiment of the present application. Figure 1 As shown, the printing and curing method of the battery core insulating coating may include the following operations:

[0099] 101. According to the insulation coating requirement parameters of the battery cell to be processed, determine the target ink required for the battery cell to be processed, and obtain the basic parameters of the target ink.

[0100] In an embodiment of the present application, optionally, the insulating coating requirement parameters include at least one of an insulating coating type requirement parameter, an insulating coating thickness requirement parameter, an insulating coating range requirement parameter, an insulating coating insulation coefficient requirement parameter, an insulating coating bubble requirement parameter, and an insulating coating color depth parameter.

[0101] 102. According to basic parameters of the target ink, a target nozzle matching the target ink is determined from a preset nozzle set.

[0102] In an embodiment of the present application, optionally, the basic parameters of the target ink include at least one of the color parameters of the target ink, an absorption spectrum, a pull-out strength parameter, a dielectric strength parameter, an adhesion parameter, a thermal conductivity coefficient, a flame retardancy coefficient, a shear strength parameter, a component parameter (such as a ratio parameter between the resin, photoinitiator, additive, monomer, color powder, etc. contained in the target ink), a concentration parameter, a viscosity parameter, a density parameter and a surface tension parameter.

[0103] 103. Determine the printing working parameters of the target nozzle, and based on the target ink and the printing working parameters of the target nozzle, perform an insulating coating printing operation on the battery cell to be processed to obtain the insulating coating to be cured of the battery cell to be processed.

[0104] In the embodiment of the present application, optionally, the printing operating parameters of the target nozzle include electrical signal parameters (the electrical signal parameters are given to the piezoelectric ceramics inside the nozzle to eject ink droplets, and the electrical signal parameters can control the printing intensity, printing duration, printing range, printing speed, etc. of the target nozzle), movement control parameters and at least one of the printing temperature control parameters.

[0105] 104. Perform a curing operation on the insulating coating to be cured of the battery cell to be processed by a preset target light-emitting curing device to obtain the cured insulating coating of the battery cell to be processed.

[0106] In the embodiment of the present application, optionally, the target light-emitting curing equipment can be an electrodeless lamp, or an LED lamp, etc. Among them, compared with electrodeless lamps, LED lamps have greatly improved in terms of cost, life, temperature rise, energy consumption, ease of operation, energy peak and pollutant generation, and are more feasible for realizing a fully automated mass production line for six-sided square battery cells.

[0107] It can be seen that the implementation of the embodiment of the present application can determine the target nozzle that matches the target ink according to the insulation coating requirement parameters of the battery cell to be processed and the basic parameters of the target ink, and determine the printing working parameters of the target nozzle, and then perform insulation coating printing on the battery cell to be processed and curing operation on the insulation coating to be cured to obtain the cured insulation coating of the battery cell to be processed, thereby improving the reliability and accuracy of determining the target nozzle and the target light-emitting curing equipment for the battery cell to be processed, and improving the intelligent production and manufacturing of the battery cell, thereby reducing the damage to the battery cell and equipment during the printing and curing process.

[0108] In an optional embodiment, the step 102 of determining a target nozzle matching the target ink from a preset nozzle set according to the basic parameters of the target ink includes:

[0109] Determine the nozzle parameters of each nozzle in the preset nozzle set;

[0110] According to the basic parameters of the target ink and the nozzle parameters of all nozzles, the printing matching degree between each nozzle and the target ink is calculated;

[0111] According to the printing matching degree between all the nozzles and the target ink, a nozzle whose printing matching degree is greater than or equal to a preset printing matching degree threshold is determined from all the nozzles as a target nozzle matching the target ink.

[0112] In this optional embodiment, the nozzle parameters of each nozzle optionally include at least one of the nozzle model parameter, ink circulation mode parameter and ink compatibility parameter of the nozzle. The matching target nozzle can make the target ink print more uniformly, reduce the generation of bubbles / excess particles, and improve the color density / viscosity of the target ink.

[0113] In other words, it can be understood that the determination of the target nozzle needs to focus on the following parts:

[0114] 1. Because the UV ink of the battery cell is corrosive to a certain extent, when selecting a nozzle, you need to pay attention to the corrosion resistance of the nozzle material to ensure durability;

[0115] 2. To ensure excellent printing quality, a high-resolution printhead is required;

[0116] 3. Because different ink formulas may be used in the production process, the printhead must have good ink compatibility to ensure that the ink compatibility is stable and reliable;

[0117] 4. For easy operation, the nozzle must be plug-and-play, quick and easy;

[0118] 5. To ensure the printing effect, the consistency of the nozzles must be ensured to improve the color density and printing uniformity, so that the droplet volume of each nozzle, droplet, and print head is more consistent;

[0119] 6. The printhead must have true internal circulation technology to ensure that the liquid can flow through the back of the nozzle under high-speed printing conditions. The internal circulation technology can prevent precipitation and nozzle clogging, and can also take away bubbles and excess particles in the ink, prevent precipitation and nozzle clogging, and can be more used in harsh industrial environments;

[0120] 7. Due to the high requirements of the battery core printing coating, the viscosity of the ink is very high, and the viscosity of the jetting fluid needs to be increased;

[0121] 8. The size of the printed droplets must be appropriate.

[0122] Furthermore, the printing matching degree between each nozzle and the target ink can be calculated according to the basic parameters of the target ink, the nozzle parameters of all nozzles and the required parameters of the insulating coating of the battery cell to be processed.

[0123] It can be seen that this optional embodiment can determine the target nozzle that matches the target ink based on the basic parameters of the target ink and the nozzle parameters of each nozzle in the preset nozzle set. In this way, it not only ensures the uniformity of the ink during the printing process and reduces the generation of bubbles and excess particles, thereby effectively improving the printing quality and color density / viscosity of the battery cell insulating coating, thereby meeting the high-demand battery cell printing coating standards; it also ensures that the nozzle maintains stable performance after long-term use. At the same time, good ink compatibility allows the nozzle to adapt to different ink formulas and reduce the occurrence of nozzle clogging, thereby improving the flexibility and efficiency of the production line.

[0124] In another optional embodiment, determining the printing working parameters of the target nozzle in step 103 includes:

[0125] The printing test parameters of the target ink are obtained, and the printing working parameters of the target nozzle are determined according to the printing test parameters of the target ink.

[0126] In this optional embodiment, further, the printing test parameters of the target ink are obtained by:

[0127] Obtain the standard driving working parameters of each printhead for the target ink;

[0128] Determine the printing condition corresponding to each nozzle when printing with the target ink according to the standard driving working parameters of all nozzles for the target ink, the nozzle parameters of each nozzle in the predetermined nozzle set and the basic parameters of the target ink;

[0129] According to the printing conditions corresponding to each nozzle when printing with the target ink, the standard driving working parameters of each nozzle for the target ink are adjusted to obtain the adjusted driving working parameters of each nozzle for the target ink;

[0130] Determine the printing test parameters of the target ink based on the adjusted driving working parameters of all printheads for the target ink.

[0131] In this optional embodiment, it can be understood that before the UV printing system is used to perform a printing test on the machine, the target ink and each nozzle need to be matched. Optionally, the printing condition includes at least one of ink bubble condition, ink particle condition, ink fluidity condition, ink shielding condition, ink splash condition, ink color condition and ink smudge condition. Further optionally, the standard drive working parameters may include at least one of standard electrical signal parameters, standard movement control parameters and standard printing temperature control parameters.

[0132] It should be noted that when adjusting the standard drive parameters of each printhead for the target ink, please pay attention to:

[0133] 1. Increasing the pressurization rate may make the ink eject faster, but too high a rate may cause ink splashing or damage to the nozzle; reducing the pressurization rate may make the ink eject slower, affecting the printing speed and effect. Therefore, for some scenes that require high-precision printing, it is necessary to appropriately reduce the pressurization rate to ensure accurate ink ejection; and for the situation of pursuing printing speed, you can try to increase the pressurization rate, but pay attention to the print quality;

[0134] 2. Extending the pulse duration usually increases the amount of ink ejected, but too long may cause excessive ink accumulation; shortening the pulse duration will reduce the amount of ink ejected and may make the image lighter;

[0135] 3. Adjusting the fit can make the adjusted driving working parameters better match the characteristics of the nozzle and improve the stability and consistency of inkjet;

[0136] 4. Use the adjusted driver working parameters to perform test printing. You can print some test patterns or simple images. Then, carefully observe the printing results and evaluate the print quality, including image clarity, color accuracy, whether there are broken lines, blurring, and other problems.

[0137] It can be seen that this optional embodiment can perform a matching test between the target ink and each nozzle, and adjust the standard drive operating parameters according to the printing situation. In this way, the standard drive operating parameters can be flexibly adjusted according to the needs of different scenarios (such as high-precision printing or the pursuit of printing speed), which can optimize the printing efficiency while ensuring the printing quality and meet the diverse needs of different customers; in addition, it also reduces ink splashing or nozzle damage caused by excessive pressurization rate, and excessive ink accumulation caused by too long pulse duration, thereby reducing maintenance costs and reducing ink waste.

[0138] Embodiment 2

[0139] See also Figure 2 , Figure 2It is a flow chart of another method for printing and curing the insulating coating of a battery cell disclosed in an embodiment of the present application. Optionally, the method can be implemented by a coating printing and curing device, which can be integrated in a coating printing and curing device, or a local server or cloud server for processing the printing and curing process of the insulating coating of the battery cell, etc., which is not limited in the embodiment of the present application.

[0140] like Figure 2 As shown, the printing and curing method of the battery core insulating coating may include the following operations:

[0141] 201. According to the insulation coating requirement parameters of the battery cell to be processed, determine the target ink required for the battery cell to be processed, and obtain the basic parameters of the target ink.

[0142] 202. According to basic parameters of the target ink, a target nozzle matching the target ink is determined from a preset nozzle set.

[0143] 203. Determine the printing working parameters of the target nozzle, and based on the target ink and the printing working parameters of the target nozzle, perform an insulating coating printing operation on the battery cell to be processed to obtain the insulating coating to be cured of the battery cell to be processed.

[0144] 204. Obtain curing test parameters of the target ink, and obtain target printing conditions of the insulating coating to be cured of the battery cell to be processed.

[0145] In the embodiment of the present application, further, the curing test parameters of the target ink are determined by the following method:

[0146] Obtaining initial device parameters of each light-emitting curing device in a preset light-emitting curing device set;

[0147] Acquire the pre-printing condition of the target ink on the preset substrate, and determine the curing condition of each light-emitting curing device for the target ink based on the pre-printing condition and the initial device parameters of each light-emitting curing device;

[0148] According to the curing condition of each light-emitting curing device for the target ink, the initial device parameters of each light-emitting curing device are adjusted to obtain the adjusted device parameters of each light-emitting curing device for the target ink;

[0149] Determine the curing test parameters of the target ink according to the adjusted device parameters of all the light-emitting curing devices for the target ink.

[0150] In this optional embodiment, optionally, the initial device parameters of each light-emitting curing device include at least one of an initial light-emitting intensity parameter, an initial light-emitting wavelength parameter, an initial light-emitting frequency parameter, and an initial light-emitting range parameter of the light-emitting curing device. Further optionally, the curing condition of each light-emitting curing device for the target ink is used to indicate the fluidity influence and / or thermal damage influence caused by the light-emitting curing device for the target ink.

[0151] It should be noted that in the process of developing curing system inks, it is necessary to select the energy of the light-emitting curing equipment, that is, to simultaneously carry out the required curing energy value range under different inks and the different ink formulas under the determined curing energy value, and continuously optimize and improve to achieve the optimal formula and curing energy. Because the UV curing process can generally be divided into the following three stages: chain initiation, chain growth and chain termination, under UV irradiation, the photoinitiator transitions to the excited state and then decomposes to produce active free radicals. The free radicals can trigger reactive polymers and active diluents to undergo polymerization reactions. After the degree of polymerization reaches a certain level or the active substances are exhausted, coupling or disproportionation termination reactions occur between the active free radicals, ending the photoreaction and forming a polymer with a three-dimensional network structure. The final curing energy value is selected by adjusting the formula of different curing system inks and testing the energy of the light-emitting curing equipment.

[0152] 205. According to the curing test parameters of the target ink, the target printing condition of the insulating coating to be cured of the battery cell to be processed and the basic parameters of the target ink, determine the target light-emitting curing device that matches the insulating coating to be cured from the preset light-emitting curing device set, and determine the curing working parameters of the target light-emitting curing device.

[0153] In the embodiment of the present application, optionally, the curing working parameters of the target light-emitting curing device include at least one of the light-emitting intensity parameter, light-emitting wavelength parameter, light-emitting frequency parameter and light-emitting range parameter of the light-emitting curing device.

[0154] 206. Perform a curing operation on the insulating coating to be cured of the battery cell to be processed by using a target light-emitting curing device and curing working parameters to obtain the cured insulating coating of the battery cell to be processed.

[0155] In the embodiment of the present application, for other descriptions of step 201 to step 203, please refer to the detailed description of step 101 to step 103 in embodiment 1, and the embodiment of the present application will not be repeated.

[0156] In the embodiment of the present application, further, the method also includes:

[0157] After obtaining the cured insulating coating of the battery cell to be processed, determining the processing effect parameters of the cured insulating coating of the battery cell to be processed;

[0158] According to the insulation coating requirement parameters of the battery cell to be processed and the treatment effect parameters of the insulation coating of the battery cell to be processed after curing, it is judged whether the insulation coating of the battery cell to be processed after curing meets the preset printing curing conditions;

[0159] When the judgment result is no, according to the processing effect parameters of the insulating coating of the battery cell to be processed after curing, the printing working parameters of the target nozzle are adjusted to obtain the adjusted printing working parameters of the target nozzle, and the printing working parameters based on the target ink and the target nozzle are triggered to perform an insulating coating printing operation on the battery cell to be processed to obtain the insulating coating to be cured of the battery cell to be processed; through the preset target light-emitting curing equipment, the insulating coating to be cured is cured to obtain the insulating coating of the battery cell to be processed; the printing working parameters are the adjusted printing working parameters.

[0160] In this optional embodiment, it is determined whether the insulating coating of the treated battery cell after curing meets the preset printing curing conditions, that is, whether the insulating coating requirement parameters of the treated battery cell and the processing effect parameters of the insulating coating of the treated battery cell after curing match each other. Optionally, the processing effect parameters of the insulating coating after curing include at least one of the curing condition, thickness parameter, range parameter, insulation coefficient, color depth parameter and coating bubble condition of the insulating coating after curing.

[0161] It can be seen that the implementation of the embodiment of the present application can determine the matching target light-emitting curing equipment through the curing test parameters of the target ink, the target printing conditions of the insulating coating to be cured of the battery cell to be processed, and the basic parameters of the target ink, and cure the insulating coating to be cured of the battery cell to be processed through the target light-emitting curing equipment and the curing working parameters. In this way, the matching degree between the insulating coating to be cured and the target light-emitting curing equipment can be improved, thereby improving the curing stability and consistency of the insulating coating to be cured of each battery cell to be processed, which is beneficial to improving the overall performance of the battery cell to be processed.

[0162] In an optional embodiment, before adjusting the printing working parameters of the target nozzle according to the processing effect parameters of the insulating coating of the battery cell to be processed after curing and obtaining the adjusted printing working parameters of the target nozzle in the above steps, the method further includes:

[0163] Determine the environmental parameters of the printing environment where the battery cells to be processed are located;

[0164] According to the environmental parameters of the printing environment, determine the printing impact of the printing environment on the target ink;

[0165] Determine the printing influence degree of the printing environment on the target ink according to the printing influence of the printing environment on the target ink, and judge whether the printing influence degree is greater than or equal to a preset printing influence degree threshold;

[0166] When the judgment result is yes, adjusting the printing working parameters of the target nozzle according to the printing influence and the processing effect parameters of the insulating coating of the battery cell to be processed after curing, to obtain the adjusted printing working parameters of the target nozzle;

[0167] When the judgment result is no, the printing working parameters of the target nozzle are adjusted according to the processing effect parameters of the insulating coating of the battery cell to be processed after curing, so as to obtain the adjusted printing working parameters of the target nozzle.

[0168] In this optional embodiment, the environmental parameters of the printing environment include at least one of the environmental temperature parameters, environmental humidity parameters and environmental air flow parameters of the printing environment. Further, the printing influence includes at least one of the ink flow influence, ink splash influence and ink bloom influence.

[0169] It should be noted that environmental parameters of the printing environment, such as temperature and humidity, may also affect the effect of the nozzle waveform. For example, in a low temperature environment, the viscosity of the ink may increase, and it may be necessary to appropriately increase the pressurization rate or extend the pulse duration to ensure normal ink ejection; while in a high humidity environment, the ink may be more easily blurred, and the corresponding parameters need to be adjusted to control the ink ejection amount and speed.

[0170] It can be seen that this optional embodiment can determine the printing impact of the printing environment on the target ink according to the environmental parameters of the printing environment in which the battery cell to be processed is located, and then further adjust the printing working parameters of the target nozzle when the printing impact is large. This not only helps to prevent problems such as poor ink fluidity, splashing or smudging caused by poor environment in advance, but also can dynamically adjust the printing working parameters of the nozzle according to the real-time environmental conditions, thereby ensuring stable and high-quality insulating coating printing effects under various environmental conditions.
