Current insulation treatment methods mostly employ electrodeless lamps to cure the cell's insulating coating.

[0097] Example 1

[0098] Please see Figure 1 , Figure 1 This is a schematic flowchart illustrating a method for printing and curing an insulating coating on a battery cell, as disclosed in an embodiment of this application. Optionally, this method can be implemented by a coating printing and curing device, which can be integrated into a coating printing and curing equipment, or it can be a local server or cloud server used to process the printing and curing process of the battery cell insulating coating, etc. This application embodiment does not impose any limitations. Figure 1 As shown, the inkjet printing and curing method for the battery cell insulating coating may include the following operations:

[0099] 101. Based on the insulation coating requirements of the battery cell to be treated, determine the target ink required for the battery cell to be treated, and obtain the basic parameters of the target ink.

[0100] In this embodiment of the application, the optional insulating coating requirement parameters include at least one of the following: insulating coating type requirement parameters, insulating coating thickness requirement parameters, insulating coating range requirement parameters, insulating coating insulation coefficient requirement parameters, insulating coating bubble requirement parameters, and insulating coating color depth parameters.

[0101] 102. Based on the basic parameters of the target ink, determine the target printhead that matches the target ink from the preset printhead set.

[0102] In the embodiments of this application, optionally, the basic parameters of the target ink include at least one of the following: color parameters, absorption spectrum, pull-out strength parameters, dielectric strength parameters, adhesion parameters, thermal conductivity, flame retardancy coefficient, shear strength parameters, composition parameters (such as the ratio parameters between the resin, photoinitiator, additives, monomers, pigments, etc. contained in the target ink), concentration parameters, viscosity parameters, density parameters, and surface tension parameters.

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

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

[0105] 104. Using a preset target light-emitting curing device, the insulating coating of the battery cell to be treated is cured to obtain the cured insulating coating of the battery cell.

[0106] In this application embodiment, optionally, the target light-curing device can be an electrodeless lamp or an LED lamp, etc. Among them, LED lamps have significant improvements over electrodeless lamps in terms of cost, lifespan, temperature rise, energy consumption, ease of operation, peak energy and pollutant generation, and are more feasible to realize a fully automated mass production line for six sides of square battery cells.

[0107] As can be seen, implementing the embodiments of this application can determine the target printhead that matches the target ink based on the insulation coating requirements of the battery cell to be processed and the basic parameters of the target ink, and determine the printing working parameters of the target printhead. Then, the insulation coating printing and curing operations of the insulation coating to be cured are performed on the battery cell to be processed to obtain the cured insulation coating of the battery cell to be processed. This improves the reliability and accuracy of determining the target printhead and the target light-emitting curing equipment for the battery cell to be processed, improves the intelligence of battery cell manufacturing, and reduces the occurrence of damage to the battery cell and equipment during the printing and curing process.

[0108] In an optional embodiment, step 102 above, which involves determining the target printhead matching the target ink from a preset set of printheads based on the target ink's basic parameters, includes:

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

[0110] Based on the basic parameters of the target ink and the printhead parameters of all printheads, calculate the printing matching degree between each printhead and the target ink;

[0111] Based on the printing matching degree between all printheads and the target ink, printheads with a printing matching degree greater than or equal to a preset printing matching degree threshold are identified as target printheads that match the target ink.

[0112] In this optional embodiment, the printhead parameters for each printhead may include at least one of the following: printhead model parameters, ink circulation mode parameters, and ink compatibility parameters. Matching the target printhead can result in more uniform printing of the target ink, reduce the generation of bubbles / excess particles, and improve the color density / viscosity of the target ink, etc.

[0113] In other words, determining the target nozzle requires focusing on the following aspects:

[0114] 1. Because the UV ink for battery cells is somewhat corrosive, when selecting a printhead, it is necessary to ensure that the printhead material is corrosion-resistant and durable;

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

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

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

[0118] 5. To ensure printing quality, it is necessary to maintain the consistency of the printhead nozzles to improve color density and printing uniformity, making the droplet volume of each nozzle, droplet, and printhead 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 flow rate printing conditions. The internal circulation technology can prevent sedimentation and nozzle clogging, and can also remove air bubbles and excess particles in the ink, thus preventing sedimentation and nozzle clogging, and making it more suitable for harsh industrial environments.

[0120] 7. Due to the high requirements for the coating of battery cells, the viscosity of the ink is very important, so the viscosity of the jetting fluid needs to be increased;

[0121] 8. The size of the ink droplets used in the printing must be appropriate.

[0122] Furthermore, the printing matching degree between each printhead and the target ink can be calculated based on the basic parameters of the target ink, the printhead parameters of all printheads, and the insulation coating requirements of the battery cell to be processed.

[0123] As can be seen, this optional embodiment can determine the target printhead that matches the target ink based on the basic parameters of the target ink and the printhead parameters of each printhead in the preset printhead set. This 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 insulation coating, thus meeting the high requirements of the battery cell printing coating standard; but also ensures that the printhead maintains stable performance even after long-term use. At the same time, good ink compatibility allows the printhead to adapt to different ink formulations, reducing nozzle clogging and thus improving the flexibility and efficiency of the production line.

[0124] In another optional embodiment, determining the printing operating parameters of the target printhead in step 103 above includes:

[0125] Obtain the printing test parameters of the target ink, and determine the printing working parameters of the target printhead based on the printing test parameters of the target ink.

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

[0127] Obtain the standard drive parameters for each printhead for the target ink;

[0128] Based on the standard drive parameters of all printheads for the target ink, the printhead parameters of each printhead in the pre-determined printhead set, and the basic parameters of the target ink, determine the printing situation of each printhead when printing with the target ink;

[0129] Based on the printing conditions of each printhead when printing with the target ink, the standard driving parameters of each printhead for the target ink are adjusted to obtain the adjusted driving parameters of each printhead for the target ink.

[0130] Based on the adjusted drive parameters of all printheads for the target ink, determine the printing test parameters for the target ink.

[0131] In this optional embodiment, it can be understood that before conducting printing tests using the UV inkjet printing system, a matching test needs to be performed on the target ink and each printhead. Optionally, the printing conditions include at least one of the following: ink bubble condition, ink particle condition, ink flow condition, ink opacity condition, ink splatter condition, ink color condition, and ink smudging condition. Further optionally, the standard drive operating parameters may include at least one of the following: 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 for each printhead for the target ink, the following should be observed:

[0133] 1. Increasing the pressurization rate may make the ink eject faster, but too high a rate may cause ink splatter or printhead damage; decreasing the pressurization rate may make the ink eject slower, affecting printing speed and quality. Therefore, for some scenarios that require high-precision printing, it is necessary to appropriately reduce the pressurization rate to ensure accurate ink ejection; while for situations that prioritize printing speed, you can try increasing the pressurization rate, but you should pay attention to the print quality.

[0134] 2. Extending the pulse duration usually increases the amount of ink ejected, but too long a duration may lead to excessive ink buildup; shortening the pulse duration will reduce the amount of ink ejected, which may make the image colors lighter.

[0135] 3. Adjusting the fit can better match the characteristics of the printhead after adjustment, thereby improving the stability and consistency of inkjet printing;

[0136] 4. Use the adjusted drive parameters to perform test prints. You can print some test patterns or simple images, and then carefully observe the print results to evaluate the print quality, including image sharpness, color accuracy, and whether there are any broken lines, smudging, or other problems.

[0137] As can be seen, this optional embodiment can perform matching tests between the target ink and each printhead, 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 pursuing printing speed), which can optimize printing efficiency while ensuring print quality and meet the diverse needs of different customers. In addition, it also reduces ink splashing or printhead damage caused by excessive pressure rate, as well as excessive ink accumulation caused by excessive pulse duration, thereby reducing maintenance costs and ink waste.

[0138] Example 2

[0139] Please see Figure 2 , Figure 2This is a schematic flowchart of another method for printing and curing the insulating coating of a battery cell disclosed in this application. Optionally, this method can be implemented by a coating printing and curing device, which can be integrated into a coating printing and curing equipment, or it can be a local server or cloud server used to process the printing and curing process of the battery cell insulating coating, etc., which is not limited in this application.

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

[0141] 201. Based on the insulation coating requirements of the battery cell to be treated, determine the target ink required for the battery cell to be treated, and obtain the basic parameters of the target ink.

[0142] 202. Based on the basic parameters of the target ink, determine the target printhead that matches the target ink from the preset printhead set.

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

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

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

[0146] Obtain the initial equipment parameters for each light-curing device in the preset set of light-curing devices;

[0147] The pre-printing status of the target ink on a preset substrate is obtained, and based on the pre-printing status and the initial equipment parameters of each light-curing device, the curing status of each light-curing device for the target ink is determined.

[0148] Based on the curing status of each light-curing device for the target ink, the initial equipment parameters of each light-curing device are adjusted to obtain the adjusted equipment parameters of each light-curing device for the target ink.

[0149] Based on the adjusted equipment parameters of all luminescent curing equipment for the target ink, determine the curing test parameters for the target ink.

[0150] In this optional embodiment, the initial equipment parameters of each light-emitting curing device may optionally include at least one of the following: initial luminescence intensity parameter, initial luminescence wavelength parameter, initial luminescence frequency parameter, and initial luminescence range parameter. Further optionally, the curing status of each light-emitting curing device for the target ink is used to indicate the flowability effect and / or thermal damage effect caused by the light-emitting curing device to the target ink.

[0151] It is important to note that the development of curing system inks requires selecting the energy level of the light-emitting curing equipment. This involves simultaneously determining the required curing energy range for different inks and optimizing various ink formulations at specific curing energy levels to achieve the optimal formulation and curing energy. The UV curing process generally consists of three stages: chain initiation, chain propagation, and chain termination. Under UV irradiation, the photoinitiator transitions to an excited state and then decomposes to generate active free radicals. These free radicals can initiate polymerization reactions with reactive oligomers and diluents. After the degree of polymerization reaches a certain level or the active material is exhausted, coupling or disproportionation between the active free radicals terminates the photoreaction, forming a three-dimensional network polymer structure. The final curing energy value is selected through adjustments to different curing system ink formulations and energy testing of the light-emitting curing equipment.

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

[0153] In this embodiment of the application, optionally, the curing parameters of the target luminescent curing device include at least one of the following: luminescence intensity parameter, luminescence wavelength parameter, luminescence frequency parameter, and luminescence range parameter.

[0154] 206. Using the target light-emitting curing equipment and curing parameters, the insulating coating of the battery cell to be treated is cured to obtain the cured insulating coating of the battery cell.

[0155] In this application embodiment, for other descriptions of steps 201-203, please refer to the detailed description of steps 101-103 in Embodiment 1. This application embodiment will not repeat them.

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

[0157] After obtaining the cured insulating coating of the battery cell to be treated, the treatment effect parameters of the cured insulating coating of the battery cell to be treated are determined.

[0158] Based on the insulation coating requirements of the battery cell to be processed and the processing effect parameters of the insulation coating after curing, determine whether the insulation coating after curing of the battery cell to be processed meets the preset printing and curing conditions.

[0159] When the judgment result is negative, the printing parameters of the target printhead are adjusted according to the processing effect parameters of the cured insulating coating of the battery cell to be processed, so as to obtain the adjusted printing parameters of the target printhead. The printing operation based on the target ink and the target printhead is triggered to perform the insulating coating printing operation on the battery cell to be processed, so as to obtain the insulating coating to be cured on the battery cell to be processed. The curing operation is performed on the insulating coating to be cured on the battery cell to be processed through the preset target light-emitting curing equipment, so as to obtain the cured insulating coating of the battery cell to be processed. The printing parameters are the adjusted printing parameters.

[0160] In this optional embodiment, determining whether the cured insulating coating of the battery cell meets the preset printing curing conditions involves determining whether the required parameters of the insulating coating of the battery cell match the processing effect parameters of the cured insulating coating. Optionally, the processing effect parameters of the cured insulating coating include at least one of the following: curing status, thickness parameters, range parameters, insulation coefficient, color depth parameters, and coating bubble condition.

[0161] As can be seen, by implementing the embodiments of this application, a matching target light-emitting curing device can be determined by the curing test parameters of the target ink, the target printing condition of the insulating coating to be cured on the battery cell to be treated, and the basic parameters of the target ink. The insulating coating to be cured on the battery cell to be treated can be cured by using the target light-emitting curing device and the curing working parameters. In this way, the matching degree between the insulating coating to be cured and the target light-emitting curing device can be improved, thereby improving the curing stability and consistency of the insulating coating to be cured on each battery cell to be treated, which is conducive to improving the overall performance of the battery cell to be treated.

[0162] In an optional embodiment, before adjusting the printing parameters of the target printhead based on the treatment effect parameters of the cured insulating coating of the battery cell to be treated in the above steps to obtain the adjusted printing parameters of the target printhead, the method further includes:

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

[0164] Based on the environmental parameters of the printing environment, determine the impact of the printing environment on the target ink.

[0165] Based on the impact of the printing environment on the target ink, determine the degree of impact of the printing environment on the target ink, and determine whether the degree of impact is greater than or equal to the preset threshold of the degree of impact.

[0166] When the judgment result is yes, adjust the printing working parameters of the target printhead according to the printing impact and the treatment effect parameters of the cured insulating coating of the battery cell to be processed, and obtain the adjusted printing working parameters of the target printhead.

[0167] When the judgment result is negative, the printing parameters of the target printhead are adjusted according to the treatment effect parameters of the cured insulating coating of the battery cell to be treated, so as to obtain the adjusted printing parameters of the target printhead.

[0168] In this optional embodiment, the environmental parameters of the printing environment may optionally include at least one of the following: ambient temperature, ambient humidity, and ambient airflow. Further optionally, the printing-related factors may include at least one of the following: ink flowability, ink splatter, and ink smudging.

[0169] It should be noted that environmental parameters of the printing environment, such as temperature and humidity, can also affect the printhead waveform. For example, in a low-temperature environment, the ink viscosity may increase, which may require appropriately increasing the pressurization rate or extending the pulse duration to ensure normal ink ejection; while in a high-humidity environment, the ink may be more prone to smudging, requiring adjustments to the corresponding parameters to control the ink ejection volume and speed.

[0170] As can be seen, this optional embodiment can determine the impact of the printing environment on the target ink based on the environmental parameters of the printing environment in which the battery cell to be processed is located. Then, if the impact on the printing environment is significant, the printing parameters of the target printhead can be further adjusted. This not only helps to prevent problems such as poor ink flow, splashing, or smudging caused by poor environment in advance, but also allows for dynamic adjustment of the printhead's printing parameters according to real-time environmental conditions, thereby ensuring a stable and high-quality insulating coating printing effect under various environmental conditions.

This not only ensures the uniformity of the ink during the printing process and reduces the generation of bubbles and excess particles, thus effectively improving the printing quality and color density / viscosity of the battery cell insulation coating, thereby meeting the high requirements of battery cell inkjet printing coating standards; but also ensures that the printhead maintains stable performance even after long-term use. At the same time, good ink compatibility allows the printhead to adapt to different ink formulations, reducing nozzle clogging and thus improving the flexibility and efficiency of the production line.
