Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a coating system and method. Background Technology

[0002] With the rapid development of the lithium battery industry, the requirements for battery production efficiency are becoming increasingly stringent. However, in the battery production process, adhesive coating, as a crucial manufacturing process, significantly impacts the structural strength of the battery, and consequently, its safety. Related technologies typically employ a fixed thickness of adhesive or interference fit coating to coat the battery. However, because the flatness of the battery's bottom surface often varies, these coating methods can lead to a mismatch between the battery's flatness and the amount of adhesive applied. This results in uneven adhesive application, overflow, or leakage, affecting not only the coating quality but also the battery's sealing and stability.

[0003] The above statements are for the purpose of providing background information in relation to this application only and do not necessarily constitute prior art. Summary of the Invention

[0004] In view of the above problems, this application provides a coating system and method that can solve the technical problem of difficulty in accurately controlling the amount of adhesive applied to batteries in related technologies.

[0005] In a first aspect, this application provides a coating system, comprising: an image acquisition device, a processor, a controller, and a coating device; the image acquisition device is used to acquire the surface area and flatness of the coating area of ​​a battery, and determine the coating volume corresponding to the coating area based on the surface area and the flatness; the processor is used to receive the coating volume sent by the image acquisition device, determine the amount of coating for the battery based on the coating volume, and send a coating control command carrying the amount of coating to the controller; the controller is connected to the coating device and is used to send the coating control command to the coating device, the coating control command carrying the coating area of ​​the battery and the amount of coating for the coating area; the coating device has a plurality of dispensing units on its dispensing surface, and the coating device is used to activate a number of dispensing units corresponding to the amount of coating to coat the coating area according to the received coating control command.

[0006] In the technical solution of this application embodiment, the battery coating process is automated and intelligent through the coordinated work of the image processing device, processor, controller, and coating device in the coating system. Furthermore, by setting multiple dispensing units on the dispensing surface of the coating device, the coating area and amount of adhesive on the battery can be precisely controlled according to different coating requirements, achieving adaptive dynamic adjustment of the dispensing amount and ensuring the uniformity and accuracy of the coating. In addition, the design of multiple dispensing units improves the efficiency of battery coating, facilitating the rapid completion of coating tasks for large areas or complex shapes. It significantly improves the problems of uneven coating or material waste caused by fixed dispensing amounts in traditional coating processes. While achieving precise control of the dispensing amount, it can also improve coating quality and production efficiency, reduce coating material waste, lower production costs, and has few limitations and high versatility.

[0007] In some embodiments of the application, the image acquisition device is used to acquire the partition surface area and partition flatness of each partition in the adhesive coating area, and determine the adhesive coating volume corresponding to each partition based on the partition surface area and partition flatness of each partition; the processor is used to receive the partition adhesive coating volume corresponding to each partition sent by the image acquisition device, determine the adhesive coating amount of each partition based on the partition adhesive coating volume, and send an adhesive coating control command carrying the adhesive coating amount of each partition to the controller.

[0008] This application embodiment divides the coating area into multiple zones and calculates the coating volume and amount for each zone separately, enabling more precise coating control and ensuring uniformity and accuracy of coating in each zone. For coating areas with complex or irregular shapes, zoned processing can better adapt to the needs of different areas, allowing the amount of adhesive in each area to be independently adjusted according to the different thicknesses, structures, and design requirements of the bottom surface. This further ensures more precise and uniform coating in different areas, effectively improving the coating quality of the battery and avoiding uneven, excessive, or insufficient coating.

[0009] In some embodiments of the application, the image acquisition device is used to acquire the surface area and flatness of each partition in the adhesive coating area of ​​the battery, determine the adhesive coating thickness of each partition according to the flatness of each partition, and determine the adhesive coating volume of each partition by multiplying the partition surface area and the adhesive coating thickness of each partition.

[0010] The processor is configured to receive the partition coating volume corresponding to each partition sent by the image acquisition device, determine the coating amount of each partition based on the partition coating volume, send a coating control command carrying the coating amount of each partition to the controller, determine the coating amount of the battery based on the coating volume, and send a coating control command carrying the coating amount to the controller.

[0011] The controller is connected to the glue coating device and is used to send a glue coating control command to the glue coating device. The glue coating control command carries the glue coating area of ​​the battery and the glue coating amount corresponding to the glue coating area.

[0012] The adhesive applicator has multiple adhesive dispensing units on its dispensing surface. The adhesive applicator is used to activate a number of dispensing units corresponding to the amount of adhesive to apply adhesive to the adhesive area according to the received adhesive control command.

[0013] In some embodiments, the dispensing ports of the plurality of dispensing units are evenly distributed on the dispensing surface of the adhesive applicator.

[0014] In this embodiment, the design of evenly distributed adhesive outlets on the adhesive dispensing surface of the coating device enables more uniform application of adhesive on the battery coating surface, avoiding uneven application and improving the coating quality of the battery. Furthermore, the evenly distributed outlets contribute to more uniform adhesive coverage, thereby enhancing battery bonding strength and improving the reliability and durability of the battery product.

[0015] In some embodiments of this application, the dispensing unit further includes a dispensing control valve, which is disposed on the dispensing pipeline of each dispensing unit; the dispensing control valve is connected to the controller, and is used to control the opening degree of the dispensing port of the dispensing unit according to the dispensing control command sent by the controller.

[0016] This embodiment of the application uses a dispensing control valve to precisely adjust the opening of the dispensing nozzle according to the controller's instructions, thereby achieving precise control of the dispensing amount. This ensures the uniformity and accuracy of the adhesive application, avoids excessive use of adhesive, reduces material waste, and lowers production costs. Furthermore, by dynamically adjusting the dispensing amount based on real-time demand, the dispensing control valve can adapt to different adhesive application tasks, improving the flexibility and adaptability of the adhesive application system.

[0020] Apply adhesive to each partition according to the amount of adhesive applied to each partition.

[0021] In some embodiments of this application, obtaining the surface area and flatness of each partition in the adhesive coating area of ​​the battery, and determining the adhesive coating volume corresponding to each partition based on the surface area and flatness of the partition, includes:

[0024] The adhesive thickness corresponding to any partition is determined based on the partition flatness of any partition, and the product of the partition surface area and the adhesive thickness corresponding to any partition is determined as the partition adhesive volume corresponding to any partition.

[0025] This application embodiment utilizes three-dimensional coordinate data and surface calculation algorithms to accurately obtain the surface area and flatness of each partition, thereby accurately calculating the adhesive coating volume for each partition. Based on the adhesive coating volume of each partition, the battery is precisely coated with adhesive. This improves coating quality and production efficiency while reducing material waste and lowering battery production costs.

[0026] In some embodiments of the application, the surface calculation algorithm includes a first surface calculation algorithm and a second surface calculation algorithm;

[0029] The maximum value between the first surface area and the second surface area is taken as the partition surface area of ​​any partition.

[0030] This application embodiment calculates the surface area using two different surface calculation algorithms and takes the maximum value as the final result. This can effectively reduce calculation errors and ensure sufficient adhesive application, thereby improving the accuracy of battery adhesive application and battery production quality.

[0031] In some embodiments of the application, obtaining the first surface area corresponding to any partition based on the three-dimensional coordinate data and according to the first surface calculation algorithm includes:

[0032] For any given partition, based on the three-dimensional coordinate data corresponding to each point in that partition, determine the projected coordinates and height coordinates of each point in the projection plane; the projection plane is the plane containing any two coordinate axes in the three-dimensional coordinate system where the three-dimensional coordinate data is located.

[0035] Determine the projection area of ​​any of the partitions on the projection plane;

[0036] On the projected region, the surface area of ​​any partition is calculated by integration based on the partial derivative.

[0037] This application embodiment projects three-dimensional coordinate data onto a two-dimensional plane and uses surface equations and integrals to calculate the surface area, which can accurately calculate the surface area of ​​each partition of the battery coating area. It can also adapt well to partitions with complex or irregular shapes, significantly improving the accuracy of surface area calculation of the battery coating area.

[0038] In some embodiments of this application, obtaining the second surface area corresponding to any partition based on the three-dimensional coordinate data and according to the second surface calculation algorithm includes:

[0039] For any given partition, determine a first parameter and a second parameter corresponding to each point in the given partition.

[0044] The embodiments of this application can accurately calculate the surface area of ​​each partition of the battery coating area by using parametric equations and vector cross products. It can also adapt well to partitions with complex or irregular shapes, significantly improving the accuracy of surface area calculation of the battery coating area.

[0045] In some embodiments of this application, applying adhesive to each partition according to the amount of adhesive applied to each partition includes:

[0046] For any partition among the partitions, based on the amount of adhesive applied to any partition, determine the number of target dispensing units to be activated corresponding to the amount of adhesive applied to that partition;

[0047] The target glue dispensing unit is controlled to apply glue to any of the partitions.

[0048] The embodiments of this application determine the target number of dispensing units based on the amount of adhesive applied to each zone and precisely control the amount of adhesive dispensed by each dispensing unit. This ensures the accuracy of the amount of adhesive applied to each zone. By controlling multiple dispensing units to work simultaneously, it is possible to quickly complete the adhesive application task for large areas or complex shapes, significantly improving the adhesive application efficiency of the battery.

[0049] In some embodiments of this application, applying adhesive to each partition according to the amount of adhesive applied to each partition includes:

[0050] For any of the partitions, the target opening of the dispensing port of each dispensing unit of the dispensing equipment is determined based on the amount of adhesive applied to any partition.

[0051] Each glue dispensing unit is controlled to apply glue to any of the partitions at its corresponding target opening.

[0057] This application embodiment achieves precise control of the coating area by working together with the image acquisition device, processor and coating device. This not only significantly improves the coating quality and production efficiency of the battery, but also reduces the waste of coating materials and lowers the production cost of the battery.

[0079] Currently, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. In electric transportation, military equipment, and aerospace, batteries are typically used to provide power.

[0080] Among various types of power batteries, lithium batteries are widely used in new energy vehicles, consumer electronics, energy storage systems and other fields due to their advantages such as high power density, high energy density, long cycle life, high output voltage and green environmental protection.

[0081] With the rapid development of the lithium battery industry, the requirements for battery production efficiency are becoming increasingly stringent. However, in the battery production process, adhesive coating, as a crucial manufacturing process, significantly impacts the structural strength of the battery, and consequently, its safety. Related technologies typically employ a fixed thickness of adhesive or interference fit coating to coat the battery. However, because the flatness of the battery's bottom surface often varies, these coating methods can lead to a mismatch between the battery's flatness and the amount of adhesive applied. This results in uneven adhesive application, overflow, or leakage, affecting not only the coating quality but also the battery's sealing and stability.

[0082] like Figure 1 As shown, current coating processes typically employ interference coating, which uses excessive adhesive to ensure adequate coverage and sealing. However, interference coating leads to wasted adhesive, increased material costs, and uneven adhesive thickness, with some areas receiving too much adhesive while others receive too little. Furthermore, interference coating easily causes overflow and dripping, affecting not only the coating effect but also potentially impacting battery production, reducing efficiency, and increasing the difficulty of subsequent processes. Therefore, traditional interference coating methods can no longer meet the demands of high-precision coating and fail to ensure the sealing and stability of battery modules.

[0083] Based on the aforementioned problems in related technologies, some embodiments of this application propose a coating system, method, storage medium, and program product. The coating system includes: an image acquisition device, a processor, a controller, and a coating device; the image acquisition device is used to acquire the surface area and flatness of the coating area of ​​the battery, and determine the coating volume corresponding to the coating area based on the surface area and flatness; the processor is used to receive the coating volume sent by the image acquisition device, determine the amount of coating for the battery based on the coating volume, and send a coating control command carrying the amount of coating to the controller; the controller is connected to the coating device and is used to send the coating control command to the coating device, the coating control command carrying the coating area of ​​the battery and the amount of coating for the coating area; the coating device has multiple dispensing units on its dispensing surface, and the coating device is used to activate a number of dispensing units corresponding to the amount of coating to coat the coating area according to the received coating control command.

[0084] In the technical solution of this application embodiment, the battery coating process is automated and intelligent through the coordinated work of the image processing device, processor, controller and coating device in the coating system. Moreover, the multiple dispensing units set on the dispensing surface of the coating device can accurately control the coating area and amount of the battery according to different coating requirements, realize adaptive dynamic adjustment of the dispensing amount, and ensure the uniformity and accuracy of the coating.

[0085] In some embodiments of this application, the battery can be, but is not limited to, a cell, a single cell, a battery module, or a battery pack. The battery can be of any chemical type, such as a lithium-ion battery, nickel-cadmium battery, nickel-metal hydride battery, or lead-acid battery. The battery can be of any shape and structure, such as a cylindrical battery, a flat battery, a pouch battery, or a prismatic battery. The battery can be applied in any application scenario requiring battery use. It can be used as a consumer electronics battery, such as in mobile phones and laptops. The battery can also be used as an energy storage battery, and as a power battery, such as in electric vehicles, electric bicycles, electric aircraft, and electric ships.

[0086] In some embodiments of this application, the battery coating equipment is used to precisely coat various parts of the battery during the battery production process. The battery coating equipment can be, but is not limited to, cell coating equipment, module coating equipment, and battery pack coating equipment. Cell coating equipment may include, but is not limited to, automatic dispensing machines and high-speed coating robots. Module coating equipment may include, but is not limited to, module packaging coating machines and insulation coating systems. Battery pack coating equipment may include, but is not limited to, battery pack packaging coating machines and battery pack insulation coating systems.

[0087] The specific structure of the adhesive coating equipment of this application is described in detail below through specific embodiments. See also... Figure 2 The schematic diagram of the adhesive application device shown shows that the adhesive application device 12 includes: a plurality of adhesive dispensing units 121; specifically, the plurality of adhesive dispensing units 121 are disposed on the adhesive dispensing surface of the adhesive application device 12, and the adhesive application device 12 is used to activate the number of adhesive dispensing units 121 corresponding to the amount of adhesive to apply adhesive to the adhesive application area according to the received adhesive application control command.

[0088] See Figure 3 The schematic diagram of the coating device shown illustrates that traditional coating equipment in related technologies only includes one dispensing unit. A single dispensing unit makes it difficult to precisely control the amount of adhesive applied to different areas. For complex shapes or high-precision workpieces requiring fine coating, traditional coating equipment may not achieve the desired coating effect. However, in this embodiment, the coating device 12 has multiple dispensing units 121 on its dispensing surface. The controller sends coating control commands to each coating device 12. These commands include information on the coating area of ​​the battery and the corresponding amount of adhesive applied, providing precise guidance for subsequent coating operations. After receiving the coating control command, the coating device 12 activates the corresponding number of dispensing units 121 to apply adhesive to the coating area according to the specified amount of adhesive. This allows for the activation of an appropriate number of dispensing units 121 based on actual production needs, enabling rapid coating of the battery and effectively improving battery production efficiency, meeting the requirements of large-scale production. It should be noted that the battery to be coated in this application can be a cell, a single cell, a battery module, a battery pack, etc.

[0089] In the technical solution of this application embodiment, by setting multiple dispensing units on the dispensing surface of the coating device, the coating area and amount of the battery can be precisely controlled according to different coating requirements, realizing adaptive dynamic adjustment of the dispensing amount, and ensuring the uniformity and accuracy of the coating. Furthermore, the design of multiple dispensing units can improve the efficiency of battery coating, facilitating the rapid completion of coating tasks for large areas or complex shapes; it significantly improves the problems of uneven coating or material waste caused by a fixed dispensing amount in traditional coating processes, and has few limitations and high versatility.

[0090] In one or more embodiments of this application, such as Figure 4 As shown, the glue outlets 121a of the plurality of glue dispensing units 121 are evenly distributed on the glue dispensing surface of the glue coating device 12.

[0091] In this embodiment, for example, the spacing between adjacent adhesive outlets 121a is the same. The design of the adhesive outlets 121a being evenly distributed on the adhesive application surface of the coating device 12 allows for more uniform application of adhesive on the battery coating surface, avoiding uneven application and improving the coating quality of the battery. Furthermore, the evenly distributed outlets contribute to more uniform adhesive coverage, thereby enhancing battery bonding strength and improving the reliability and durability of the battery product.

[0092] In one or more embodiments, such as Figure 5 As shown, the dispensing unit 121 further includes a dispensing control valve 122, which is disposed on the dispensing pipeline of each dispensing unit 121. The dispensing control valve 122 is connected to the controller and is used to control the opening degree of the dispensing port 121a of the dispensing unit according to the dispensing control command sent by the controller.

[0093] Specifically, in this embodiment, the dispensing control valve 122, upon receiving a control command from the controller, controls the opening degree of the dispensing port 121a of its respective dispensing unit. The opening degree can range from 0% to 100%.

[0094] like Figure 4 As shown, in one example, the coating device 12 includes nine dispensing units 121. After the controller determines the coating area of ​​the battery and the corresponding coating amount, it determines that the coating amount of the current coating area is 9mg. At this time, the controller sends coating control commands to each of the nine dispensing units 121. The dispensing control valves 122 of the nine dispensing units 121 control the opening degree of the dispensing port 121a of their respective dispensing units to be fully open (100%). When the coating amount of the current coating area is determined to be 5mg, the controller sends coating control commands to five of the nine dispensing units 121. The dispensing control valves 122 of the five dispensing units 121 control the opening degree of the dispensing port 121a of their respective dispensing units to be fully open (100%). In another example, the coating amount of the current coating area is determined to be 4.5mg. mg, at this time the controller 11 sends glue application control commands to the nine glue dispensing units 121 respectively, and the glue dispensing control valve 122 of the nine glue dispensing units 121 controls the opening degree of the glue outlet 121a of the respective glue dispensing unit to be half open (50%).

[0095] This embodiment of the application uses a dispensing control valve to precisely adjust the opening of the dispensing nozzle according to the controller's instructions, thereby achieving precise control of the dispensing amount. This ensures the uniformity and accuracy of the adhesive application, avoids excessive use of adhesive, reduces material waste, and lowers production costs. Furthermore, by dynamically adjusting the dispensing amount based on real-time demand, the dispensing control valve can adapt to different adhesive application tasks, improving the flexibility and adaptability of the adhesive application system.

[0096] This application also provides an adhesive application system, such as... Figure 6 As shown, the adhesive application system 1 includes: an image acquisition device 30, a processor 20, a controller 11, and an adhesive application device 12;

[0097] The image acquisition device 30 is used to acquire the surface area and flatness of the adhesive coating area of ​​the battery, and to determine the adhesive coating volume corresponding to the adhesive coating area based on the surface area and the flatness.

[0098] The processor 20 is used to receive the adhesive volume sent by the image acquisition device 30, determine the amount of adhesive applied to the battery based on the adhesive volume, and send an adhesive application control command carrying the amount of adhesive applied to the controller 11.

[0099] The controller 11 is connected to the glue application device 12 and is used to send glue application control instructions to each of the glue application devices 12. The glue application control instructions carry the glue application area of ​​the battery and the glue application amount corresponding to the glue application area.

[0100] The glue applicator 12 has multiple glue dispensing units on its glue dispensing surface. The glue applicator 12 is used to activate a number of glue dispensing units corresponding to the amount of glue to apply glue to the glue application area according to the received glue application control command.

[0101] Specifically, in this embodiment, the image acquisition device 30 can be a three-dimensional line scan laser measuring instrument, a 3D line laser profile measuring instrument, a lidar, or other similar equipment. It should be noted that the image acquisition device 30 is also equipped with an image data processing system, which can analyze the shape, size, and flatness of the object's surface to generate a high-precision surface profile model. Based on this surface profile model, the adhesive volume can be calculated, comprehensively reflecting the flatness changes of the object's surface to be coated, providing basic data for subsequent adhesive coating control operations.

[0102] like Figure 7As shown, in one example, the scanning area (battery pack) is divided into multiple partitions. A 3D line scanner emits a laser beam, which is then directed onto the bottom surface of the pack. The laser beam reflects off the bottom surface of the pack and is captured by the scanner's receiving module. By analyzing information such as the time, angle, and intensity of the reflected laser beam using the 3D line scanner, the 3D data of each partition on the bottom surface of the pack can be calculated more accurately. In one example, the average height value of multiple points in the partition is taken based on the aforementioned 3D data as the flatness of the partition. Based on this flatness and a preset adhesive thickness, the height of the partition can be determined. The adhesive volume of the partition can be determined by multiplying this height by the partition's surface area. In another example, the flatness of the partition can be determined by taking the height values ​​of multiple points in the partition based on a preset fitting function and the aforementioned 3D data. The adhesive volume of the partition can be determined by multiplying this flatness by the partition's surface area.

[0103] The image acquisition device 30 described above is the front-end data acquisition and processing unit of the system. Its main function is to obtain detailed information about the battery coating area, including surface area and flatness. Through high-precision scanning or sensing technology, this device can generate a three-dimensional data model of the coating area, providing a basis for subsequent coating amount calculation.

[0104] The processor 20 described above serves as the intermediate control layer of the system. Connected to the image acquisition device 30 and the controller 11, the processor 20 transmits data and forwards instructions. Furthermore, the processor 20 receives adhesive volume information from the image acquisition device 30, determines the specific amount of adhesive to be applied based on preset algorithms and rules, and then sends a control instruction containing the adhesive amount to the controller 11. It should be noted that the processor 20 can also be implemented using a host computer.

[0105] Combination Figure 2 As shown, the glue applicator 12 serves as the execution unit of the glue applicator system 1, and is directly responsible for the glue applicator operation. The glue applicator 12 has multiple glue dispensing units 121 on its dispensing surface. The controller receives the glue applicator control command sent by the host computer 20, parses the glue applicator area and glue amount, and controls the glue applicator 12 to perform precise glue applicator operations based on the glue applicator area and glue amount.

[0106] The coating system of this application embodiment achieves automation and intelligence in the battery coating process through the coordinated work of an image acquisition device, a processor, a controller, and a coating device. Moreover, while achieving precise control of the amount of adhesive dispensed, it can improve coating quality and production efficiency, reduce waste of coating materials, and lower production costs. It can be widely applied in multiple fields.

[0107] In some embodiments of the application, the image acquisition device 30 is used to acquire the partition surface area and partition flatness of each partition in the adhesive coating area, and determine the adhesive coating volume corresponding to each partition based on the partition surface area and partition flatness of each partition; the processor 20 is used to receive the partition adhesive coating volume corresponding to each partition sent by the image acquisition device 30, determine the adhesive coating amount of each partition based on the partition adhesive coating volume, and send an adhesive coating control command carrying the adhesive coating amount of each partition to the controller 11.

[0108] Specifically, in this embodiment, a three-dimensional data model of the adhesive application area is generated by the image acquisition device 30. Based on the three-dimensional data model, a surface calculation algorithm and curvature analysis method are used to calculate the surface area and flatness of each partition. According to these parameters combined with the preset adhesive thickness and adhesive properties, the adhesive volume of each partition can be calculated.

[0109] The processor 20 receives the partitioned adhesive application volume sent by the image acquisition device 30 through the communication interface, parses and stores this data. It calculates the adhesive application amount for each partition based on the partitioned adhesive application volume. The calculation results are encapsulated into adhesive application control commands and sent to the controller 11 through the communication interface.

[0110] The adhesive applicator 12 receives adhesive control commands from the processor 20 via its controller 11, and parses the adhesive amount and order for each zone. Based on the adhesive amount, it activates a corresponding number of dispensing units 121, and precisely controls the dispensing amount of each dispensing unit via the dispensing control valve 122. The adhesive applicator 12 applies adhesive to each zone according to a preset adhesive path and order. Figure 8 As shown, the glue dispensing rate per unit time is changed according to the surface area and flatness. This means that during the glue application process, the glue dispensing rate can be dynamically adjusted according to the surface area and flatness of each zone in the glue application area, which can significantly reduce the situation of glue overflowing from the edges.

[0111] This application embodiment divides the coating area into multiple zones and calculates the coating volume and amount for each zone separately, enabling more precise coating control and ensuring uniformity and accuracy of coating in each zone. For coating areas with complex or irregular shapes, zoned processing can better adapt to the needs of different areas, allowing the amount of adhesive in each area to be independently adjusted according to the different thicknesses, structures, and design requirements of the bottom surface. This further ensures more precise and uniform coating in different areas, effectively improving the coating quality of the battery and avoiding uneven, excessive, or insufficient coating.

[0115] S906, Apply adhesive to each partition according to the amount of adhesive applied to each partition.

[0116] Specifically, in this embodiment of the application, the three-dimensional data of the adhesive coating area of ​​the battery is acquired by the image acquisition device. The average height value of multiple points in the partition is taken as the flatness of the partition based on the three-dimensional data. The height of the partition can be determined based on the flatness and the preset adhesive coating thickness. The adhesive coating volume of the partition can be determined based on the product of the height and the surface area of ​​the partition.

[0117] The processor receives adhesive volume data for each zone from the image acquisition device. Based on this data and pre-defined adhesive application rules and algorithms, it calculates the specific amount of adhesive to be applied to each zone. The processor then encapsulates the calculated adhesive amounts for each zone into adhesive application control commands and sends them to the controller. The controller receives these commands, parses the adhesive amount and application sequence for each zone, and activates the corresponding number of dispensing units based on the required amount. The controller precisely controls the dispensing volume of each dispensing unit via dispensing control valves. The adhesive application device then applies adhesive precisely to each zone according to the pre-defined path and sequence, ensuring uniformity and accuracy of the adhesive application.

[0149] Specifically, in this application, the first surface calculation algorithm can be used to calculate the parametric equations of the surface;

[0150] For the parametric equations, the base equations are as follows:

The calculation formula is as follows: Where n is the number of partitions. By calculating the total amount of adhesive applied to the battery surface, the flatness fluctuation of the battery after adhesive application can be evaluated, avoiding sudden large or small volumes in the battery after adhesive application, thus improving the production quality of the battery.

[0158] For any partition among the partitions, based on the amount of adhesive applied to any partition, determine the number of target dispensing units to be activated corresponding to the amount of adhesive applied to that partition;

[0159] The target glue dispensing unit is controlled to apply glue to any of the partitions.

[0160] Specifically, in the embodiments of this application, combined with Figure 4 and Figure 6 As shown, in one example, the adhesive applicator 12 includes 9 adhesive dispensing units. Assuming that the controller 11 determines the adhesive application area of ​​the battery and the corresponding adhesive amount information, and determines that the adhesive amount of the current partition is 9mg, the controller 11 sends adhesive application control commands to the 9 adhesive dispensing units respectively, and controls the 9 adhesive dispensing units to apply adhesive to the current partition.

[0161] Assuming that the controller 11 determines that the amount of glue applied to the current partition is 5mg, the controller 11 sends a glue application control command to 5 of the 9 glue application units. The glue application control valve 122 of the 5 glue application units controls the 5 glue application units to apply glue to the current partition.

[0166] Specifically, in the embodiments of this application, such as Figure 4As shown, in one example, the coating device 12 includes 9 dispensing units 121. After the controller 11 determines the coating area of ​​the battery and the corresponding coating amount information, it determines that the coating amount of the current partition is 9mg. At this time, the controller 11 sends coating control commands to the 9 dispensing units 121 respectively. The dispensing control valves 122 of the 9 dispensing units 121 control the dispensing ports 121a of their respective dispensing units to apply adhesive to the current partition with the target opening degree of all being fully open (100%).

At this time, the controller 11 sends glue application control commands to the nine glue dispensing units 121 respectively. The glue dispensing control valves 122 of the nine glue dispensing units 121 control the glue outlets 121a of their respective glue dispensing units to apply glue to the current partition with the target opening degree of half open (50%).

Then, based on the scan results and the preset adhesive application height, a three-dimensional volumetric model of the adhesive volume is created. During this process, the bottom surface of the PACK is divided into sections to improve the accuracy of the volumetric model.

[0171] Once the adhesive volume model is completed, the data is transmitted to a host computer. The host computer then uses a Programmable Logic Controller (PLC) to control the transmission of the data to the adhesive application robot. Based on the established volume model, the corresponding adhesive dispensing amount is calculated for different zones, ultimately achieving an adaptive adhesive application process.

After scanning, the geometric data is uploaded to the image data processing system, which then analyzes the shape, size, and flatness of the bottom surface of the pack to generate a high-precision bottom surface contour model. This model comprehensively reflects the flatness variations of the bottom surface of the pack, providing basic data for subsequent adaptive variable adhesive coating control.

The calculation formula is as follows: , where n is the number of regions to be divided.

[0186] In practical operation, the controller system incorporates a specialized library for scientific computing, specifically designed for precise numerical integration calculations. By processing the 3D line scan data, the results are accurately input into the aforementioned bottom surface area model. The outputs of the two calculation methods are compared and analyzed, and the larger result is selected as the basis for determining the adhesive volume, ensuring a sufficient and appropriate amount of adhesive is applied.

[0189] The glue application equipment has multiple independently controllable zone nozzles. Through connection with the data processing system, the glue dispensing volume and dispensing rate of the nozzles can be automatically adjusted according to the needs of each zone. Specifically, the glue amount calculation result in the previous step is transmitted to the host computer, which converts the data into PLC signals and transmits them to the glue application robot. The glue application robot then performs adaptive glue application according to the pre-programmed glue application program.

[0190] S5. Glue application: Each zone nozzle adjusts its glue dispensing volume in real time based on the glue volume and system feedback.

[0191] The adhesive application robot is equipped with multiple nozzles that can be independently controlled for each zone. Each nozzle adjusts its dispensing volume in real time based on the adhesive volume and system feedback to ensure uniform adhesive distribution in different areas. Based on the high and low elevations identified in the scanned data, the system can dynamically adjust the nozzle's spray rate and adhesive volume. For example, in recessed areas, the system automatically increases the adhesive volume to ensure coverage; while in raised areas, it reduces the adhesive volume to ensure a uniform coating.

[0192] This application utilizes 3D scanning technology to establish a volumetric adhesive model, enabling an adhesive application robot to perform adaptive variable adhesive application and achieving precise control of the adhesive application process on the bottom surface of the battery. The system can automatically adjust the adhesive distribution based on the bottom surface shape, defect areas, and other characteristics, ensuring uniform and high-quality adhesive application while reducing waste of structural adhesive.
