However, in actual printing processes, uneven ink droplet impact angles in the curved transition area and delayed UV curing response often lead to drip defects. This results in ink accumulation or incomplete coverage in the R-corner area where the cylindrical surface of the battery connects to the explosion-proof valve surface or the terminal surface, leading to low yield rates on the production line.

[0065] like Figure 1 and Figure 2 As shown, this application embodiment proposes a laser curing module, including a mounting bracket 1 and a laser emitting device 2;

[0066] Mounting bracket 1 is set on the main frame of the cylindrical battery printing system and located below the clamping and rotating mechanism 3 of the cylindrical battery printing system; the clamping and rotating mechanism 3 is used to clamp and fix the cylindrical battery.

[0067] A laser emitting device 2 is mounted on the mounting bracket 1. The laser emitting device 2 includes two laser pointers, and the laser beams emitted by the two laser pointers are respectively aimed at the R-angles at both ends of the cylindrical battery.

[0068] In this embodiment, a laser curing module is added during the cylindrical battery printing process. The laser emitting device 2, while printing ink onto the cylindrical battery, irradiates the R-corners at both ends of the cylindrical battery with a laser beam, thereby achieving rapid pre-curing of the ink at the R-corners of the battery. This avoids ink loss due to untimely final curing, resulting in uneven ink coverage and ink spreading, reducing ink accumulation or incomplete coverage, thereby improving the yield rate of the production line, reducing rework, reducing equipment wear and tear, and saving economic costs.

[0069] The aforementioned R-angle refers to the junction between the battery terminal surface or explosion-proof valve surface and the cylindrical curved surface.

[0070] The aforementioned laser pointer can achieve instant correction of the surface morphology of rounded corners using a non-contact photothermal effect. The power of the laser pointer can be controlled by adjusting the duration of coil energization and the power supply. Because the laser spot diameter is ≤0.5mm, the printhead ejection starting point error can be reduced from ±1.0mm to ±0.05mm, effectively eliminating structural white spots caused by misalignment.

[0071] In some embodiments, a mounting frame 1 is provided on the main frame of the cylindrical battery printing system, and a laser emitting device 2 is provided on the mounting frame 1. The mounting frame 1 may include a mounting frame body and an adjustment bracket provided on the mounting frame body. The number of adjustment brackets is the same as the number of laser pointers, and each laser pointer is provided on one adjustment bracket.

[0072] In this embodiment, the adjustable bracket allows for flexible adjustment of the specific position and angle of the laser pointer in the laser emitting device 2, better adapting to the printing needs of different types of cylindrical batteries. Since different types of cylindrical batteries differ in parameters such as diameter and length, this setup ensures that the laser beams emitted by the two laser pointers are precisely aligned with the corresponding R-angle positions at both ends of the cylindrical battery, achieving effective printing and curing of batteries of different specifications.

[0073] In some embodiments, the laser curing module includes multiple laser emitting devices 2 arranged side by side on the mounting frame 1.

[0074] In this embodiment, since multiple batteries are typically placed side-by-side for simultaneous printing in the system, the laser curing module can include multiple laser emitting devices 2 arranged side-by-side on the mounting bracket 1. The side-by-side arrangement of these laser emitting devices allows for simultaneous irradiation and pre-curing of multiple batteries, improving printing efficiency and facilitating unified control and management of batteries in different positions, making the entire printing and curing process more orderly and efficient. Furthermore, the spacing between the multiple laser emitting devices 2 can be flexibly adjusted according to the battery arrangement, further enhancing the system's adaptability to printing batteries of different specifications.

[0075] like Figure 3 As shown, this application also proposes a laser curing method for controlling a laser curing module as described in any of the above embodiments. The laser curing method includes the following steps:

[0076] Step 101: In response to the clamping position command, control the laser curing module to start; wherein, the laser curing module is initialized in advance according to the acquired laser curing parameters, including preset laser power and preset working time;

[0077] Step 102: When the working time of the laser curing module reaches the preset working time, control the laser curing module to stop working.

[0078] In this embodiment, the parameters related to the power and irradiation time of the laser curing module, specifically the laser emitting device 2, can be preset according to the battery production speed and printing requirements. For example, when the production speed is high, the power of the laser emitting device 2 can be appropriately increased and the irradiation time shortened to ensure that the pre-curing of the ink at the battery's R-corner is completed in a short time; when the production speed is slow, the power can be reduced and the irradiation time extended to ensure a more uniform and stable ink pre-curing effect.

[0079] Understandably, the preset working time corresponds to the printing process duration. In some cases, the preset working time is equal to the printing process duration, meaning the laser pointer is only turned on and illuminates the screen during the printing process. In other cases, the preset working time can be longer than the printing process duration, meaning the laser pointer can be turned on before printing begins or illuminate the screen for a period of time after printing ends before being turned off.

[0080] In some embodiments, the laser curing method may further include adjusting the angle of the adjustment bracket according to the battery model of the cylindrical battery, so that the laser beam emitted by the laser pointer is precisely aligned with the R-angles at both ends of the cylindrical battery.

[0081] In this embodiment, the adjustment bracket on the mounting frame 1 can be controlled to flexibly adjust the specific position and angle of the laser pointer set on the adjustment bracket, so as to better adapt to the printing needs of different types of cylindrical batteries. Since the diameter, battery length and other parameters of different types of cylindrical batteries are different, this setting can ensure that the laser beam emitted by the laser pointer is accurately aligned with the R-angle positions at both ends of the cylindrical battery, so as to achieve effective printing and curing of batteries of different specifications.

[0082] The laser curing method provided in this application can be executed by a laser curing device 200. This application uses the laser curing device 200 executing the laser curing method as an example to illustrate the laser curing device 200 provided in this application.

[0083] Please see Figure 4 This is a schematic diagram of the structure of a laser curing device 200 provided in an embodiment of this application. Figure 4 As shown, the laser curing device 200 includes:

[0084] The startup module 201 is used to control the laser curing module to start in response to the clamping position command; wherein, the laser curing module is initialized in advance according to the acquired laser curing parameters, including preset laser power and preset working time;

[0085] The stop module 202 is used to control the laser curing module to stop when the working time of the laser curing module reaches the preset working time.

[0086] Since the laser curing device 200 adopts all the technical solutions of the laser curing method of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0087] like Figures 5 to 8 As shown, this application also proposes a cylindrical battery printing system, including a magnetic levitation transport module, a lifting mechanism 4, a clamping and rotating mechanism 3, a printing module 5, a laser curing module as described in any of the first aspect embodiments above, a final curing module 6, and a control module.

[0088] The magnetic levitation conveyor module includes a conveyor belt and a tray located on the conveyor belt, the tray being used to load cylindrical batteries to be printed;

[0089] Lifting mechanism 4 is used to lift the cylindrical batteries on the tray to a preset height;

[0090] The clamping and rotating mechanism 3 is used to clamp and fix the two ends of the cylindrical battery at a preset height, and rotates around the central axis during the printing process so that the clamped cylindrical battery rotates.

[0091] Printing module 5 is used for cylindrical printing of cylindrical batteries;

[0092] The laser curing module as described in any of the embodiments of the first aspect above;

[0093] Final curing module 6 is used to irradiate and solidify the cylindrical battery after printing is completed;

[0094] The control module is electrically connected to the magnetic levitation conveying module, the lifting mechanism 4, the clamping and rotating mechanism 3, the printing module 5, the laser curing module, and the final curing module 6. The control module is used to coordinate and control the lifting mechanism 4, the clamping and rotating mechanism 3, the printing module 5, the laser curing module, and the final curing module 6 to perform cylindrical printing and curing operations on the cylindrical battery.

[0095] In this embodiment, by adding a laser curing module during the cylindrical battery printing process, the laser curing module irradiates the R-corners at both ends of the cylindrical battery while printing ink onto the battery. This achieves rapid pre-curing of the ink at the R-corners, thereby preventing ink loss due to untimely final curing, which can lead to uneven ink coverage and ink spreading. It also reduces ink accumulation or incomplete coverage, thereby improving the yield rate of the production line, reducing rework, lowering equipment wear and tear, and saving economic costs.

[0096] It is understandable that the cylindrical battery printing system, including the main frame, magnetic levitation conveying module, lifting mechanism 4, clamping and rotating mechanism 3, printing module 5, laser curing module, final curing module 6, and human-machine interaction module 7, can all be mounted on the main frame, specifically as follows: Figure 5 As shown. It should be noted that, in Figures 6 to 8 The mainframe rack was not shown in the image. Figure 7 Printing module 5 is not shown in the image. Figure 8 The printing module 5 and the final solidification module 6 are not shown in the document.

[0097] The aforementioned magnetic levitation conveyor module uses magnetic levitation technology to enable efficient and stable transport of battery-loaded trays between workstations on the production line via conveyor belts.

[0098] The aforementioned lifting mechanism 4 can vertically lift the battery from the tray to a preset height after the battery tray arrives at the printing station and is precisely positioned, detaching it from the tray surface. This ensures that the printing operation is performed directly on the cylindrical surface of the battery, avoiding ink contamination of the tray surface, eliminating the risk of cross-contamination, and ensuring the tray's reusability. Specifically, as shown... Figure 2 or Figure 8 As shown, the lifting mechanism 4 can include two lifting supports, each used to support both ends of the cylindrical battery. The top of each lifting support has a groove to accommodate the cylindrical battery, facilitating easier lifting. It is understood that the magnetic levitation transport module is not shown in the figure, but its actual position should be between the two lifting supports.

[0099] The aforementioned rotating clamping mechanism can reliably clamp both ends of the battery after it has been lifted off the tray by the lifting mechanism 4 and reached a preset height. After clamping, it can drive the cylindrical battery to rotate precisely and uniformly around its central axis. This provides a stable cylindrical curved surface printing reference for the printing execution system, ensuring the continuity and consistency of the printed graphic in the circumferential direction. Specifically, as... Figure 1 , Figure 2 or Figure 8 As shown, the above-mentioned rotating clamping mechanism may include two horizontally placed clamping columns and a rotary motor that can control the rotation of the clamping columns. When clamping a cylindrical battery, the end faces of the two clamping columns press against the two end faces of the cylindrical battery. It can be understood that the central axis of the clamping column coincides with the central axis of the cylindrical battery. Therefore, after clamping and fixing the cylindrical battery, the clamping column only needs to rotate around the central axis to drive the cylindrical battery to rotate.

[0100] The aforementioned printing module 5 can perform cylindrical printing on a uniformly rotating cylindrical battery. Printing module 5 can actually include a printing module motion system and a printing actuator. The control module can control the servo drivers of the corresponding module axes in the printing module motion system to achieve module operation, support and drive the printing actuator to perform high-precision, high-stability linear motion along a preset trajectory. Subsequently, the control module can control the printing actuator to complete the printing. It can be understood that the preset trajectory of the printing module motion system is parallel to the central axis of the cylindrical battery, so that the printing actuator can move along the axial direction of the battery's cylindrical surface to complete the printing on the cylindrical surface. Figure 5 or Figure 6 As shown, the printing actuator includes a print control board and a print head assembly. The print control board, acting as a lower-level device, receives instructions from the upper-level device (control module) to control the print head assembly, controlling the ink ejection from the corresponding print heads to achieve precise inkjet printing. Specifically, it can control the timing, position, and volume of ink droplets ejected from the print heads to achieve high-precision graphic printing on the target surface.

[0101] The aforementioned curing module 6 can perform curing by irradiating the cylindrical battery after printing. Curing module 6 can use UV curing, i.e., ultraviolet light irradiation to cure the ink on the surface of the cylindrical battery. It is understood that curing module 6 can also include a curing module motion system, similar in structure to the printing module motion system. It can also use a PLC to control the servo driver of the corresponding module axis to achieve module operation, supporting and driving the curing device to perform high-precision, high-stability linear motion along a preset trajectory to complete the curing. The preset trajectory is parallel to the central axis of the cylindrical battery, allowing it to scan at a uniform speed along the axial direction of the battery's cylindrical surface, ensuring that the entire printed surface receives uniform curing energy, or stopping at a designated position for curing, such as... Figure 5 , Figure 6 or Figure 7 As shown.

[0102] The aforementioned laser curing module, such as Figure 1 , Figure 2 or Figure 8 As shown, the system may include a mounting bracket 1 and a laser emitting device 2. The laser emitting device 2 is mounted on the mounting bracket 1 and includes two laser pointers. The laser beams emitted by the two laser pointers are respectively aimed at the R-angles at both ends of the cylindrical battery. The function of the laser curing module, as described above, is to irradiate the R-angles at both ends of the cylindrical battery while printing inkjet, achieving rapid ink pre-curing. In practical applications, the installation and debugging of the laser curing module are crucial. During installation, it is essential to ensure that the laser emitting device 2 is positioned accurately and that the laser beams emitted by the two laser pointers are precisely aimed at the R-angles at both ends of the cylindrical battery. During debugging, parameters such as the power and working time of the laser pointers need to be adjusted according to the characteristics of different cylindrical battery models to achieve the best pre-curing effect. Simultaneously, the laser emitting device 2 should be regularly inspected and maintained to ensure its normal operation and avoid affecting the printing quality and efficiency of the battery due to equipment failure.

[0103] It is understandable that, such as Figure 1 , Figure 2 or Figure 8 As shown, the printing process for each cylindrical battery requires a lifting mechanism 4, a clamping and rotating mechanism 3, and a laser curing module. The cylindrical battery printing system includes multiple lifting mechanisms 4, clamping and rotating mechanisms 3, and laser curing modules, enabling simultaneous batch printing of multiple cylindrical batteries. In some cases, the laser curing module includes a mounting frame 1 and a laser emitting device 2; the laser emitting device 2 is mounted on the mounting frame 1, which is located below the clamping and rotating mechanism 3 of the cylindrical battery printing system. When the clamping and rotating mechanism 3 is not holding a battery and printing is not required at this position, the corresponding laser emitting device 2 below must avoid directly irradiating the print head, because the print head energy cannot exceed a certain value, specifically 50 μW / cm². 2 The laser will directly irradiate the print head, and the energy of the laser pointer will cause the print head to become clogged. Therefore, the laser pointer at the corresponding position can be turned on only when there is a battery waiting to be printed at the current printing station. Alternatively, although the laser pointers can be turned on in batches, they can be raised to the corresponding upward irradiation angle only when there is a battery waiting to be printed at the current printing station, so as to avoid the laser irradiating the print head when printing without a battery.

[0104] The aforementioned control module, as the core of the entire cylindrical battery printing system, directly impacts the quality and efficiency of the printing and curing operations through its coordinated control capabilities. This control module can utilize a Programmable Logic Controller (PLC) or an industrial computer, employing precise control programs to achieve accurate control of the magnetic levitation conveyor module, lifting mechanism 4, clamping and rotating mechanism 3, printing module 5, laser curing module, and final curing module 6. During actual operation, the control module needs to monitor the working status of each module in real time and adjust control parameters promptly based on feedback information to ensure the stability and reliability of the entire printing and curing process.

[0105] In some cases, the control module can control the entire cylindrical battery printing system. When the cylindrical battery to be printed is transported to the printing station via the magnetic levitation conveyor module, the control module, after obtaining the corresponding information or instructions, specifically controls the battery printing and laser control through the following steps: It calls the corresponding battery parameters to control the lifting mechanism 4 to lift the battery to the corresponding printing height; it controls the clamping and rotating mechanism 3 to clamp the battery, and once the battery is clamped, it controls the rotating motor to rotate; simultaneously, it controls the movement of the printing actuator to bring the print head to the designated printing position and controls the print head to dispense ink; while dispensing ink, it also obtains the battery model and calls the corresponding battery parameters to control the laser emitting device 2 to emit light according to the corresponding parameters, achieving rapid curing of the battery's radius (R-angle).

[0106] In some implementations, such as Figure 5 As shown, the cylindrical battery printing system can also include a human-machine interface module 7, facilitating operation and management by operators. The human-machine interface module 7 can be a display screen, keyboard and mouse, or a touch screen, and a corresponding human-machine interface (HMI) should be developed. The HMI serves as the control and operation interface for the entire system, including operation interfaces for each actuator, parameter setting interfaces, alarm interfaces, etc. It can intuitively display the system's working status, parameter settings, and fault information, and facilitate operators in setting working parameters, starting and stopping the operation of each module, and diagnosing and troubleshooting system faults. For example, the PLC can automatically adapt battery parameters based on the selected battery model obtained from the HMI, meeting the requirements of different battery lengths or different workstations for the spraying trajectory, enabling rapid model changeover.

[0107] In some implementations, to improve the intelligence and automation of the entire cylindrical battery printing system, sensors and monitoring devices can be added to the system. For example, a position sensor can be installed on the magnetic levitation transport module to monitor the position and operating status of the tray in real time; a pressure sensor and a flow sensor can be installed on the printing module 5 to monitor the working pressure of the print head and the ink flow rate; and a temperature sensor and a light sensor can be installed on the laser curing module and the final curing module 6 to monitor parameters such as irradiation intensity and temperature. These sensors and monitoring devices can transmit the collected data to the control module in real time. The control module analyzes and processes this data to achieve intelligent control and optimization of the system.

[0108] like Figure 9 As shown in the embodiments of this application, a cylindrical battery printing method is also proposed, applied to a cylindrical battery printing system as described in any of the above embodiments. The cylindrical battery printing method includes the following steps:

[0109] Step 301: Obtain printing process parameters, including battery model, rotation speed, laser curing parameters, printing speed, and number of passes;

[0110] Step 302: Control the magnetic levitation conveying module to transport the battery to the printing station, and control the lifting mechanism 4 to lift the cylindrical battery to be printed to the preset height;

[0111] Step 303: According to the battery model, control the clamping and rotating mechanism 3 to clamp the cylindrical battery, and drive the cylindrical battery to rotate at a constant speed according to the rotation speed.

[0112] Step 304: In response to the clamping position command, control the laser curing module to work;

[0113] Step 305: In response to the start printing signal, control the printing module 5 to print the cylindrical battery on the cylindrical surface according to the battery model, printing speed and number of passes.

[0114] Step 306: After printing is completed, control the final curing module 6 to irradiate and cure the cylindrical battery until the ink on the cylindrical surface of the battery is cured.

[0115] Step 307: After the ink on the cylindrical surface has solidified, control the clamping rotation mechanism 3 to stop rotating and release the clamp;

[0116] Step 308: Control the lifting mechanism 4 to lower the cylindrical battery to the magnetic levitation conveying module, and control the magnetic levitation conveying module to move the cylindrical battery to the next work station.

[0117] In this embodiment, by adding a laser curing module during the cylindrical battery printing process, the laser curing module irradiates the R-corners at both ends of the cylindrical battery while printing ink onto the battery. This achieves rapid pre-curing of the ink at the R-corners, thereby preventing ink loss due to untimely final curing, which can lead to uneven ink coverage and ink spreading. It also reduces ink accumulation or incomplete coverage, thereby improving the yield rate of the production line, reducing rework, lowering equipment wear and tear, and saving economic costs.

[0118] In some cases, operators can select the battery model via the HMI. The HMI will load pre-set process parameters into the PLC, including printing speed, rotation speed, laser curing parameters, and number of passes. After pressing the start button, the system waits for the magnetic levitation conveyor module to transport the tray carrying the battery to the printing station. The servo-driven lifting mechanism 4 vertically lifts the battery to the preset height, completely detaching the bottom of the battery from the tray plane to prevent ink contamination. Once the battery reaches the preset height, the clamping and rotating mechanism 3 clamps the battery according to the length corresponding to the selected battery model and drives the battery to rotate precisely and uniformly around its central axis. After the battery is clamped and rotated, the laser curing module turns on the laser at the set power. The printing module 5 transports the print head from the ink pressure stop position to the printing start position, waits for the printing software to start printing signal, and then begins printing. It moves to the printing end position according to the preset battery length, and the laser pointer turns off after a set delay after printing begins. In some cases, after printing is completed, it can be determined whether the printing station needs to print multiple times. If multiple printing is required, the module will print the cylindrical battery multiple times according to the preset number of prints, i.e., the number of times it will print. Otherwise, the final solidification module 6 will move to the battery printing station to solidify the ink on the cylindrical surface of the printed battery. After completion, the clamping and rotating mechanism 3 will stop rotating and open, the lifting mechanism 4 will lower to receive the material, place the battery in the tray, and move it to the next station via the conveyor belt for subsequent processing.

[0119] In some implementations, the laser curing module is controlled to operate in response to a clamping positioning command, including:

[0120] In response to the clamping position command, the laser curing module is started; the laser curing module is pre-initialized according to the acquired laser curing parameters, including preset laser power and preset working time;

[0121] When the laser curing module has been in operation for the preset time, the laser curing module will stop working.

[0122] In this embodiment, the parameters related to the power and irradiation time of the laser curing module, specifically the laser emitting device 2, can be preset according to the battery production speed and printing requirements. For example, when the production speed is high, the power of the laser emitting device 2 can be appropriately increased and the irradiation time shortened to ensure that the pre-curing of the ink at the battery's R-corner is completed in a short time; when the production speed is slow, the power can be reduced and the irradiation time extended to ensure a more uniform and stable ink pre-curing effect.

[0123] In some implementations, the corresponding laser curing parameters can be obtained based on the pre-known battery model. A scalable process parameter database can be established. Initially, specific parameters are manually input into the HMI. During the battery production and printing process, the data for different batteries is automatically switched through the interaction of PLC and MES. Currently, flexible parameter configuration is supported for different models of cylindrical batteries, such as cylindrical batteries with diameters of 6-40mm and curvature radii of 0.5-3mm.

[0124] In some implementations, industrial-scale verification has shown that adding laser curing to conventional cylindrical battery printing methods can improve the uniformity of the black layer in the R-corner area to over 98.5%, increase the production line yield to over 99.2%, and increase unit capacity by 30% and reduce overall energy consumption by 18% by reducing rework steps. Compared to traditional hot air blowing or mechanical polishing solutions, this method has advantages such as strong process adaptability, low equipment wear and tear, and significant environmental benefits, providing a key process innovation path.
