[0001] The present application relates to the technical field of batteries, and in particular to a glue coating system and method. Background Art

[0002] With the rapid development of the lithium battery industry, the production efficiency requirements of batteries are getting higher and higher. However, in the process of battery production, glue coating, as an important manufacturing process, greatly affects the structural strength of the battery, and thus affects the product safety of the battery. In related technologies, a fixed thickness of glue coating amount or an interference glue coating method is usually used to coat the battery. Since the flatness of the bottom of the battery usually changes, the above glue coating methods will result in a mismatch between the flatness of the battery and the glue output amount, resulting in phenomena such as uneven glue amount, glue overflow or glue leakage. This will not only affect the glue coating quality of the battery, but also affect the sealing performance and stability of the battery.

[0039] Currently, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydraulic, thermal, wind and solar power stations, but also widely used in electric transportation such as electric bicycles, electric motorcycles, electric vehicles, as well as in multiple fields such as military equipment and aerospace. In fields such as electric transportation supply, military equipment, and aerospace, power is usually provided by batteries.

[0040] Among various types of power batteries, due to the advantages of high power density, high energy density, long cycle life, high output voltage, and environmental friendliness, lithium batteries are widely used in new energy vehicles, consumer electronics, energy storage systems and other fields.

[0041] With the rapid development of the lithium battery industry, the production efficiency requirements for batteries are getting higher and higher. However, in the process of battery production, glue coating, as an important manufacturing process, greatly affects the structural strength of the battery and thus affects the product safety of the battery. In related technologies, a fixed-thickness glue coating amount or an interference glue coating method is usually used to coat the battery. However, due to the variation in the flatness of the battery bottom, the above glue coating methods will result in a mismatch between the battery flatness and the glue output, causing phenomena such as uneven glue amount, glue overflow, or glue leakage. This will not only affect the glue coating quality of the battery but also affect the sealing and stability of the battery.

[0042] As Figure 1 shown, the current glue coating process usually adopts an interference glue coating method, that is, excessive glue coating is used to ensure the coverage area and pressing effect of the glue layer. However, interference glue coating will cause waste of the glue coating amount, increase the cost of the glue coating material, and the thickness of the glue layer is often uneven. Some areas to be coated may be coated too much, while other areas may be coated insufficiently. Secondly, interference glue coating is also prone to phenomena such as glue overflow and glue flow, which not only affect the glue coating effect but may also have a negative impact on the battery production process, reducing production efficiency and increasing the difficulty of subsequent processes. Therefore, the traditional interference glue coating method can no longer meet the requirements of high-precision glue coating and is difficult to ensure the sealing and stability of the battery module.

[0043] Based on the above problems existing in the related technologies, some embodiments of the present application propose a glue coating system, method, storage medium, and program product. The glue coating system includes: an image acquisition device, a processor, a controller, and a glue coating device; the image acquisition device is used to obtain the surface area and flatness of the glue coating area of the battery, and determine the glue coating volume corresponding to the glue coating area according to the surface area and the flatness; the processor is used to receive the glue coating volume sent by the image acquisition device, determine the glue coating amount of the battery according to the glue coating volume, and send a glue coating control instruction carrying the glue coating amount to the controller; the controller is connected to the glue coating device and is used to send a glue coating control instruction to the glue coating device, and the glue coating control instruction carries the glue coating area of the battery and the glue coating amount corresponding to the glue coating area; a plurality of glue output units are arranged on the glue output surface of the glue coating device, and the glue coating device is used to coat the glue coating area by enabling the number of glue output units corresponding to the glue coating amount according to the received glue coating control instruction.

[0044] In the technical solution of the embodiments of the present application, through the collaborative work of the image processing device, processor, controller, and glue coating device in the glue coating system, the automation and intelligence of the battery glue coating process are realized. Moreover, by arranging a plurality of glue output units on the glue output surface of the glue coating device, according to different glue coating requirements, the glue coating area and glue coating amount of the battery can be accurately controlled, the adaptive dynamic adjustment of the glue output amount can be realized, and the uniformity and accuracy of the glue coating can be ensured.

[0045] In some embodiments of the present application, the battery may be, but is not limited to, a battery cell, a single battery, a battery module, or a battery pack, etc. The battery may be a battery of any chemical type, such as a lithium-ion battery, a nickel-cadmium battery, a nickel-metal hydride battery, a lead-acid battery, etc. The battery may be a battery of any shape and structure, such as a cylindrical battery, a flat battery, a soft-pack battery, a square battery, etc. The battery may be applied to any application scenario where a battery is needed. The battery may be used as a consumer electronics battery, such as for mobile phones, laptops, etc. The battery may also be used as an energy storage battery, and the battery may also be used as a power battery, such as for electric vehicles, electric bicycles, electric aircraft, electric ships, etc.

[0046] In some embodiments of the present application, the battery gluing device is a device for precisely gluing various parts of the battery during the battery production process. The battery gluing device may be, but is not limited to, a battery cell gluing device, a module gluing device, a battery pack gluing device, etc. Among them, the battery cell gluing device may include, but is not limited to, an automatic dispensing machine, a high-speed gluing robot, etc. The module gluing device may include, but is not limited to, a module encapsulation gluing machine, an insulation gluing system, etc. The battery pack gluing device may include, but is not limited to, a battery pack encapsulation gluing machine, a battery pack insulation gluing system, etc.

[0047] The specific structure of the gluing device of the present application will be described in detail below through specific embodiments. Refer to Figure 2 The structural schematic diagram of the gluing device shown. The gluing device 12 includes: a plurality of glue dispensing units 121; specifically, the plurality of glue dispensing units 121 are arranged on the glue dispensing surface of the gluing device 12, and the gluing device 12 is used to enable the corresponding number of glue dispensing units 121 according to the received gluing control instruction to glue the gluing area.

[0048] Refer to Figure 3Schematic structural diagram of the glue application device shown. The glue application equipment in the related art only includes one glue outlet unit. It is difficult for a single glue outlet unit to precisely control the glue application amount in different areas. For workpieces with complex shapes or high-precision requirements that require fine glue application, the traditional glue application equipment may not achieve the ideal glue application effect. In the glue application device 12 of the embodiment of the present application, a plurality of glue outlet units 121 are arranged on the glue outlet surface. The controller sends glue application control instructions to each glue application device 12, and these instructions contain the glue application area of the battery and the corresponding glue application amount information, which can provide precise guidance for subsequent glue application operations. After receiving the glue application control instructions, the glue application device 12 will, according to the specified glue application amount in the instructions, activate the corresponding number of glue outlet units 121 to apply glue to the glue application area. In this way, it is realized to activate an appropriate number of glue outlet units 121 according to actual production requirements to quickly apply glue to the battery, effectively improving the battery production efficiency and meeting the requirements of mass production. It should be noted that the battery to be glued in the present application can be a battery cell, a single battery, a battery module, a battery pack (Pack), etc.

[0049] In the technical solution of the embodiment of the present application, by arranging a plurality of glue outlet units on the glue outlet surface of the glue application device, it is possible to precisely control the glue application area and glue application amount of the battery according to different glue application requirements, realize the adaptive dynamic adjustment of the glue output amount, and ensure the uniformity and accuracy of glue application. In addition, through the design of multiple glue outlet units, the efficiency of battery glue application can be improved, facilitating the rapid completion of glue application tasks for large areas or complex shapes; significantly improving the problems of uneven glue application or material waste caused by a fixed glue output amount in the traditional glue application process, with small limitations and high universality.

[0050] In one or more embodiments of the present application, as Figure 4 shown, the glue outlet ports 121a of the plurality of glue outlet units 121 are evenly distributed on the glue outlet surface of the glue application device 12.

[0051] In the embodiment of the present application, for example, the distance between adjacent two glue outlet ports 121a is the same. Through the design that the glue outlet ports 121a are evenly distributed on the glue outlet surface of the glue application device 12, it can make the glue be coated more evenly on the glue application surface of the battery, avoid the situation of uneven glue application, and improve the glue application quality of the battery. Moreover, the evenly distributed glue outlet ports contribute to achieving a more uniform glue coverage, thereby enhancing the battery bonding strength and improving the reliability and durability of the battery product.

[0052] In one or more embodiments, as Figure 5As shown, the glue discharging unit 121 further includes a glue discharging control valve 122, and the glue discharging control valve 122 is arranged on the glue discharging pipeline of each glue discharging unit 121; the glue discharging control valve 122 is connected to the controller, and the glue discharging control valve 122 is used to control the opening degree of the glue discharging port 121a of the affiliated glue discharging unit according to the glue coating control instruction sent by the controller.

[0053] Specifically, in the embodiment of the present application, after receiving the control instruction sent by the controller, the above-mentioned glue discharging control valve 122 controls the opening degree of the glue discharging port 121a of the affiliated glue discharging unit. The value range of the opening degree here can be from 0% to 100%.

[0054] As Figure 4 shown, in an example, for example, the glue coating device 12 includes 9 glue discharging units 121. After the controller determines the glue coating area of the battery and the corresponding glue coating amount information, it is determined that the glue coating amount in the current glue coating area is 9 mg. At this time, the controller sends glue coating control instructions to the 9 glue discharging units 121 respectively, and the glue discharging control valves 122 of the 9 glue discharging units 121 control the opening degrees of the glue discharging ports 121a of the affiliated glue discharging units to be in the fully open (100%) state; when it is determined that the glue coating amount in the current glue coating area is 5 mg, at this time, the controller sends glue coating control instructions to 5 of the 9 glue discharging units 121 respectively, and the glue discharging control valves 122 of the 5 glue discharging units 121 control the opening degrees of the glue discharging ports 121a of the affiliated glue discharging units to be in the fully open (100%) state; in another example, it is determined that the glue coating amount in the current glue coating area is 4.5 mg. At this time, the controller 11 sends glue coating control instructions to the 9 glue discharging units 121 respectively, and the glue discharging control valves 122 of the 9 glue discharging units 121 control the opening degrees of the glue discharging ports 121a of the affiliated glue discharging units to be in the half-open (50%) state.

[0055] In the embodiment of the present application, the glue discharging control valve accurately adjusts the opening degree of the glue discharging port according to the instruction of the controller, thereby realizing the precise control of the glue discharging amount, ensuring the uniformity and accuracy of the glue coating, and also being able to avoid the overuse of glue, reduce material waste, and lower the production cost. In addition, based on the glue discharging control valve dynamically adjusting the glue discharging amount according to real-time requirements, it can adapt to different glue coating tasks, improving the flexibility and adaptability of the glue coating system.

[0056] The embodiment of the present application also provides a glue coating system, as Figure 6 shown, the glue coating system 1 includes: an image acquisition device 30, a processor 20, a controller 11, and a glue coating device 12; The image acquisition device 30 is used to obtain the surface area and flatness of the glue coating area of the battery, and determine the glue coating volume corresponding to the glue coating area according to the surface area and the flatness; The processor 20 is configured to receive the glue application volume sent by the image acquisition device 30, determine the glue application amount of the battery according to the glue application volume, and send a glue application control instruction carrying the glue application amount to the controller 11; The controller 11 is connected to the glue application device 12 and is configured to send a glue application control instruction to each of the glue application devices 12. The glue application control instruction carries the glue application area of the battery and the glue application amount corresponding to the glue application area; A plurality of glue application units are arranged on the glue outlet surface of the glue application device 12. The glue application device 12 is configured to enable the number of glue application units corresponding to the glue application amount according to the received glue application control instruction to apply glue to the glue application area.

[0057] Specifically, in the embodiment of the present application, the image acquisition device 30 may be a three-dimensional line scanning laser measuring instrument, a 3D line laser profile measuring instrument, a lidar, or other devices. It should be noted that the above image acquisition device 30 is also configured with an image data processing system, which can analyze the shape, size, and flatness of the object surface, generate a high-precision surface contour model, and calculate the glue application volume according to the surface contour model, which can comprehensively reflect the flatness change of the surface of the object to be glued and provide basic data for subsequent glue application control operations.

[0058] As Figure 7 shown, in an example, the scanning area (battery pack Pack) is divided into multiple partitions. The 3D line scanner emits laser light and irradiates the bottom surface of the Pack. The laser beam is reflected back from the bottom surface of the Pack and captured by the receiving module of the scanner. By analyzing information such as the time, angle, and intensity of the reflected laser by the 3D line scanner, the three-dimensional data of each partition in the bottom surface of the Pack can be calculated more accurately; in an example, according to the above three-dimensional data, the average height value of multiple points in the partition is taken as the flatness corresponding to the partition. According to the flatness and the preset glue application thickness, the height corresponding to the partition can be determined, and the glue application volume of the partition can be determined by multiplying the height and the surface area of the partition. In another example, it may be to determine the flatness corresponding to the partition according to the preset fitting function and the height values of multiple points in the partition in the above three-dimensional data, and the glue application volume of the partition can be determined by multiplying the flatness and the surface area of the partition.

[0059] The above image acquisition device 30 is the front-end data acquisition and processing unit of the system, and its main function is to obtain detailed information of the battery glue application area, including the surface area and flatness. Through high-precision scanning or sensing technology, the device can generate a three-dimensional data model of the glue application area, providing a basis for subsequent glue application amount calculation.

[0060] The above-mentioned processor 20 serves as the intermediate control layer of the system. The processor 20 is connected to the image acquisition device 30 and the controller 11, playing the role of data transfer and instruction forwarding. In addition, the processor 20 also receives the glue application volume information from the image acquisition device 30, determines the specific glue application amount according to the preset algorithms and rules, and then sends the control instruction with the glue application amount to the controller 11. It should be noted that the processor 20 here can also be implemented by a host computer.

[0061] Combined with Figure 2 As shown, the glue application device 12 serves as the execution unit of the glue application system 1, and the glue application device 12 is directly responsible for the glue application operation. A plurality of glue outlet units 121 are provided on the glue outlet surface of the glue application device 12. The controller 11 receives the glue application control instruction sent by the host computer 20, analyzes the glue application area and the glue application amount, and controls the glue application device 12 to perform precise glue application operations according to the glue application area and the glue application amount.

[0062] The glue application system of the embodiments of the present application realizes the automation and intelligence of the battery glue application process through the coordinated work of the image acquisition device, the processor, the controller, and the glue application device. Moreover, while achieving precise control of the glue output amount, it can also improve the glue application quality and production efficiency, reduce the waste of glue application materials, lower the production cost, and can be widely applicable to multiple fields.

[0063] In some embodiments of the application, the image acquisition device 30 is used to obtain the partition surface area and partition flatness of each partition in the glue application area, and respectively determine the glue application volume corresponding to each partition according to the partition surface area and partition flatness of each partition; the processor 20 is used to receive the partition glue application volume corresponding to each partition sent by the image acquisition device 30, determine the glue application amount of each partition according to the partition glue application volume, and send a glue application control instruction carrying the glue application amount of each partition to the controller 11.

[0064] Specifically, in the embodiments of the present application, a three-dimensional data model of the glue application area is generated by the image acquisition device 30, and based on the three-dimensional data model, a surface calculation algorithm and a curvature analysis method are used to calculate the surface area and flatness of each partition. According to these parameters combined with the preset glue application thickness and glue properties, the glue application volume of each partition can be calculated.

[0065] The processor 20 receives the partition glue application volume sent by the image acquisition device 30 through the communication interface, analyzes and stores these data. Calculate the glue application amount of each partition according to the partition glue application volume. Package the calculation result into a glue application control instruction and send it to the controller 11 through the communication interface.

[0066] The glue - applying device 12 parses the glue - applying amount and glue - applying sequence of each partition based on the glue - applying control instruction sent by the processor 20 received by its controller 11. It enables the corresponding number of glue - discharging units 121 according to the glue - applying amount, and precisely controls the glue - discharging amount of each glue - discharging unit through the glue - discharging control valve 122. The glue - applying device 12 applies glue to each partition according to the preset glue - applying path and sequence. As Figure 8 shown, the glue - discharging amount per unit time is changed according to the surface area and flatness, which means that during the glue - applying process, the glue - discharging amount can be dynamically adjusted according to the surface area and flatness of each partition in the glue - applying area. In this way, the situation of glue overflowing from the edge can be significantly reduced.

[0067] In the embodiment of the present application, by dividing the glue - applying area into multiple partitions and calculating the glue - applying volume and glue - applying amount of each partition respectively, more precise glue - applying control can be achieved, ensuring the uniformity and accuracy of glue - applying for each partition. For a glue - applying area with a complex or irregular shape, partition processing can better adapt to the requirements of different areas, enabling the glue amount of each area to be independently adjusted according to the different thicknesses, structures, and design requirements of the bottom surface, further ensuring that the glue - applying amounts of different areas are more precise and uniform, effectively improving the glue - applying quality of the battery and avoiding situations such as uneven, excessive, or insufficient glue - applying.

[0068] The embodiment of the present application also provides a glue - applying method. Refer to Figure 9 the flowchart of the glue - applying method shown. This method specifically includes the following steps: S902, obtain the partition surface area and partition flatness of each partition in the glue - applying area of the battery, and determine the glue - applying volume corresponding to each partition according to the partition surface area and partition flatness; S904, obtain the glue - applying volume corresponding to each partition, and determine the partition glue - applying amount of each partition according to the glue - applying volume; S906, apply glue to each partition according to the partition glue - applying amount of each partition.

[0069] Specifically, in the embodiment of the present application, three - dimensional data of the glue - applying area of the battery is obtained according to the image acquisition device. The average height value of multiple points in the partition is taken as the flatness corresponding to the partition according to the above three - dimensional data. According to this flatness and the preset glue - applying thickness, the height corresponding to the partition can be determined. The glue - applying volume of the partition can be determined according to the product of this height and the partition surface area.

[0070] The processor receives the glue application volume data of each partition sent by the image acquisition device, and calculates the specific glue application amount of each partition according to the received glue application volume data, in combination with the preset glue application rules and algorithms. The processor encapsulates the calculated glue application amounts of each partition into glue application control instructions and sends them to the controller. The controller receives the glue application control instructions sent by the processor, parses out the glue application amounts and glue application order of each partition, enables the corresponding number of glue discharging units according to the glue application amounts, and precisely controls the glue discharging amount of each glue discharging unit through the glue discharging control valve. The glue application device performs precise glue application on each partition according to the preset glue application path and order, thereby ensuring the uniformity and accuracy of glue application.

[0071] An embodiment of the present application also provides a glue application method, which is applied to the glue application system in the above embodiment. The method specifically includes the following steps: S1. Obtain the partition surface area and partition flatness of each partition in the glue application area of the battery through the image acquisition device, and determine the glue application volume corresponding to each partition according to the partition surface area and partition flatness; S2. Receive the glue application volume corresponding to each partition sent by the image acquisition device through the processor, and determine the partition glue application amount of each partition according to the glue application volume; S3.

[0072] In one or more embodiments of the present application, the obtaining the partition surface area and partition flatness of each partition in the glue application area of the battery, and determining the glue application volume corresponding to each partition according to the partition surface area and partition flatness includes: Obtain the three-dimensional coordinate data corresponding to each partition, and obtain the partition surface area of each partition based on the three-dimensional coordinate data and the preset surface calculation algorithm; For any one of the partitions, determine the partition flatness of the any one partition based on the three-dimensional coordinate data; Determine the glue application thickness corresponding to the any one partition according to the partition flatness of the any one partition, and determine the product of the partition surface area and the glue application thickness corresponding to the any one partition as the partition glue application volume corresponding to the any one partition.

[0073] Through the three-dimensional coordinate data and the surface calculation algorithm, the embodiment of the present application can accurately obtain the surface area and flatness of each partition, thereby accurately calculating the glue application volume of each partition, and performing precise glue application on the battery according to the glue application volume of each partition. While improving the glue application quality and production efficiency, it can also reduce material waste and lower the production cost of the battery.

[0074] In some embodiments of the application, the surface calculation algorithm includes a first surface calculation algorithm and a second surface calculation algorithm; Obtaining the partition surface area of each partition based on the three-dimensional coordinate data and a preset surface calculation algorithm includes: For any one of the partitions, based on the three-dimensional coordinate data, obtain the first surface area corresponding to the any one of the partitions according to the first surface calculation algorithm; based on the three-dimensional coordinate data, obtain the second surface area corresponding to the any one of the partitions according to the second surface calculation algorithm; Take the maximum value of the first surface area and the second surface area as the partition surface area of the any one of the partitions.

[0075] In the implementation of this application, the surface areas are calculated respectively by two different surface calculation algorithms, and the maximum value is taken as the final result, which can effectively reduce the calculation error and ensure sufficient glue application amount, improving the accuracy of battery glue application and the quality of battery production.

[0076] In some embodiments of the application, obtaining the first surface area corresponding to the any one of the partitions based on the three-dimensional coordinate data according to the first surface calculation algorithm includes: For the any one of the partitions, determine the projection coordinates and height coordinates of each point in the projection plane according to the three-dimensional coordinate data corresponding to each point in the any one of the partitions; the projection plane is the plane where any two coordinate axes are located in the three-dimensional coordinate system where the three-dimensional coordinate data is located; Create a surface equation function with the height coordinate as the dependent variable and the projection coordinate as the independent variable; Calculate the partial derivative of the surface equation function with respect to the projection coordinate; Determine the projection area of the any one of the partitions on the projection plane; On the projection area, calculate the partition surface area of the any one of the partitions based on the partial derivative through integration.

[0077] Specifically, in the implementation of this application, the first surface calculation algorithm can be an explicit function for calculating the surface of the curved surface; Suppose the surface is represented by the explicit function where x, y, and z respectively represent the coordinate values of any point in the three-dimensional coordinate system, then the surface area of the partition can be expressed as:

[0078] In the formula, and are the partial derivatives of the function with respect to and ; D is the projection area of the surface corresponding to the partition on the xy plane (projection plane).

[0079] In the embodiments of the present application, by projecting three-dimensional coordinate data onto a two-dimensional plane and using a surface equation and integral to calculate the surface area, the surface area of each partition in the battery glue application area can be accurately calculated, and it can also well adapt to partitions with complex or irregular shapes, significantly improving the accuracy of calculating the surface area of the battery glue application area.

[0080] In some embodiments, obtaining the second surface area corresponding to any partition based on the three-dimensional coordinate data according to the second surface calculation algorithm includes: For any partition, determining a first parameter and a second parameter corresponding to each point in the any partition, where the first parameter is the position parameter of the three-dimensional data processing device in the moving direction, and the second parameter is the position parameter in the direction perpendicular to the moving direction; Constructing a parameter equation according to the three-dimensional coordinate data corresponding to each point in the any partition, and the first parameter and the second parameter; Calculating a first partial derivative vector corresponding to the parameter equation and the first parameter, and a second partial derivative vector corresponding to the parameter equation and the second parameter; Obtaining the vector cross product result of the first partial derivative vector and the second partial derivative vector; Performing a double integral on the modulus of the vector cross product result in the parameter domain to obtain the partition surface area of the any partition; the parameter domain includes the first parameter and the second parameter.

[0081] Specifically, in the implementation of the present application, the first surface calculation algorithm may be to calculate the parameter equation of the surface; For the form of the parameter equation, the bottom surface equation is as follows:

[0082] Where and are two parameters describing the surface position, and these two parameters are the motion parameters of the image acquisition device, that is is defined as the main direction of the scanning path of the image acquisition device, is defined as the position within each scan line. The calculation formula for the bottom surface area A of each partition in the area to be glued is:

[0083] Where and are the partial derivatives of the bottom surface of the partition, represents the cross product of vectors, represents the modulus of the vector, that is, the cross product result, D is and 's domain.

[0084] In the embodiments of the present application, through the methods of parametric equations and vector cross products, the surface area of each partition in the battery gluing area can be accurately calculated, and it can well adapt to partitions with complex or irregular shapes, significantly improving the accuracy of calculating the surface area of the battery gluing area.

[0085] In an embodiment of the application, after the surface area model of the bottom surface of the battery to be glued is established, based on the partition gluing height obtained by the three-dimensional data processing device in the above embodiment and the partition surface area , the total gluing amount of the entire surface of the battery to be glued can be obtained by cumulative calculation, and its calculation formula is , where n is the number of divided partitions. By calculating the total gluing amount of the surface of the battery to be glued, the flatness fluctuation situation after battery gluing can be evaluated, avoiding the situation that the volume of the battery suddenly becomes very large or very small after gluing, and improving the production quality of the battery.

[0086] In one or more embodiments of the application, the step of gluing each partition according to the partition gluing amount of each partition includes: For any one of the partitions, according to the partition gluing amount of the partition, determine the number of target glue outlet units corresponding to the partition gluing amount; Control the target glue outlet units to glue the partition.

[0087] Specifically, in the embodiments of the present application, as shown in Figure 4 and Figure 6 , in an example, for example, the gluing device 12 includes 9 glue outlet units. Assume that after the controller 11 determines the gluing area of the battery and the corresponding gluing amount information, and determines that the gluing amount of the current partition is 9 mg. At this time, the controller 11 sends gluing control instructions to the 9 glue outlet units respectively, and controls the 9 glue outlet units to glue the current partition.

[0088] Assume that when the controller 11 determines that the gluing amount of the current partition is 5 mg, at this time, the controller 11 sends gluing control instructions to 5 of the 9 glue outlet units, and the glue outlet control valves 122 of the 5 glue outlet units control the 5 glue outlet units to glue the current partition.

[0089] In the embodiments of the present application, by determining the number of target glue outlet units according to the partition gluing amount and accurately controlling the glue output amount of each glue outlet unit, the accuracy of the gluing amount of each partition can be ensured. By controlling multiple glue outlet units to work simultaneously, the gluing task for a large area or complex shape can be completed quickly, significantly improving the gluing efficiency of the battery.

[0091] Specifically, in an embodiment of the application, as Figure 4 shown, in an example, for example, the glue application device 12 includes 9 glue outlet units 121. After the controller 11 determines the glue application area of the battery and the corresponding glue application amount information, when it is determined that the glue application amount of the current partition is 9 mg, the controller 11 sends glue application control instructions to the 9 glue outlet units 121 respectively. The glue outlet control valves 122 of the 9 glue outlet units 121 control the glue outlets 121a of their respective glue outlet units to apply glue to the current partition in a state where the target opening degree is fully open (100%).

[0092] In another example of the application, when it is determined that the glue application amount of the current glue application area is 4.5 mg, the controller 11 sends glue application control instructions to the 9 glue outlet units 121 respectively. The glue outlet control valves 122 of the 9 glue outlet units 121 control the glue outlets 121a of their respective glue outlet units to apply glue to the current partition in a state where the target opening degree is half open (50%).

[0093] The embodiment of the application determines the target opening degree of each glue outlet unit according to the glue application amount of the partition, and accurately controls the glue output amount of each glue outlet unit, which can ensure the accuracy of the glue application amount of each partition, avoid excessive use of glue, reduce waste of glue application materials, and reduce the production cost of the battery.

[0094] Based on the above embodiments, in an application embodiment, as Figure 10 shown, the above glue application method includes: Scanning the contour of the bottom surface of the PACK using a 3D line scanner (image acquisition device) to obtain accurate geometric data. Subsequently, a three-dimensional volume model of the glue amount is established according to the scanning result and the preset glue application height. During this process, the bottom surface of the PACK is partitioned to improve the accuracy of the volume model.

[0095] After the glue amount volume model is completed, the data is transmitted to the host computer, and then the host computer controls through a Programmable Logic Controller (PLC) to transmit the data to the glue application robot. According to the established volume model, the corresponding glue output amounts are calculated for different partitions, and finally an adaptive variable glue application process is realized.

As Figure 7 shown, through 3D laser line scanning technology, the bottom surface of the battery pack PACK is scanned with high precision to obtain all-round geometric data of the bottom surface. After the scanning is completed, the geometric data is uploaded to the image data processing system, and then the shape, size, and flatness of the PACK bottom surface are analyzed to generate a high-precision bottom surface contour model, comprehensively reflecting the flatness change of the PACK bottom surface, providing basic data for subsequent adaptive variable glue coating control.

[0098] S2. Determine the glue coating volume corresponding to each partition according to the scanned three-dimensional data.

[0099] The image data processing module performs real-time analysis and processing on the three-dimensional data obtained by 3D scanning. The analysis process includes but is not limited to the following: First, shape and surface analysis: The system automatically identifies the geometric shape of the PACK bottom surface and accurately calculates the surface features of each region. Second, glue coating amount requirement calculation: By analyzing the bottom surface geometric shape and characteristic regions, the system calculates the required glue volume for the overall and local regions according to the preset glue coating standard. This process can accurately match the glue coating requirements and avoid insufficient or excessive glue amount.

[0100] After the 3D line scanning is completed, the control system uses the display function and parametric equation to model and calculate the bottom surface.

[0101] Suppose the surface is represented by the explicit function , where x, y, and z represent the coordinate values of any point in the three-dimensional coordinate system; the surface area of the PACK bottom surface can be expressed as:

[0102] In the formula, and are the partial derivatives of the function with respect to and ; D is the projection area of the surface on the xy plane.

[0103] For the form of the parametric equation, the bottom surface equation is as follows:

[0104] where and are arbitrary parameters describing the position of the 3D laser line surface. These two parameters are the motion parameters of the scanning device, that is, is defined as the main direction of the scanning path, is defined as the position within each scan line. The calculation formula for the bottom surface area A of the Pack is:

[0105] where, and are the partial derivatives of the surface, represents the cross product of vectors, represents the magnitude of the vector, that is, the result of the cross product, D is a parameter and are the domains of definition.

[0106] After establishing the bottom surface area model, based on the local glue application height and the local surface area obtained by the 3D line scanning device in the previous step, the final glue application amount can be obtained through cumulative calculation, and its calculation formula is , where n is the number of divided regions.

[0107] In specific operations, a professional library for scientific computing is embedded in the controller system, which is specifically used for accurate calculation of numerical integration. By processing the 3D line scanning data, the obtained results are accurately input into the above bottom surface area model, and the outputs of the two calculation methods are compared and analyzed, and the larger calculation result is selected as the basis for the glue application volume to ensure sufficient and appropriate glue application amount.

[0108] S3. Send the data corresponding to the above glue application volume to the host computer.

[0109] S4. Perform adaptive variable glue application for each partition of the area to be glued.

[0110] The glue application device has multiple independently controllable partition nozzles. Through connection with the data processing system, the glue output amount and output rate of the nozzles can be automatically adjusted according to the requirements of each partition. The specific implementation method is: the calculation result of the glue application amount in the previous step is transmitted to the host computer, and the host computer converts the data into PLC signals and sends them to the glue application robot. The glue application robot realizes adaptive glue application according to the written glue application program.

[0111] S5. Each partition nozzle of the glue application adjusts its glue output amount in real time according to the glue application volume and system feedback.

[0112] The glue - applying robot is equipped with multiple glue nozzles that can be independently controlled in zones. Each zone's glue nozzle adjusts its glue output in real - time according to the glue - applying volume and system feedback to ensure the uniform distribution of the glue - applying volume in different areas. According to the high - low and undulating areas identified in the scanned data, the system can dynamically adjust the spraying rate and glue volume of the glue nozzles. For example, in a sunken area, the system will automatically increase the glue volume to ensure coverage; while in a convex area, the glue volume will be reduced to ensure the uniformity of the coating.

[0113] This application combines 3D scanning technology to establish a glue - volume model, enabling the glue - applying robot to achieve adaptive variable glue - applying and realizing precise control of the glue - applying process on the battery bottom surface. The system can automatically adjust the glue - volume distribution according to features such as the bottom - surface shape and defective areas, ensuring the uniformity and high quality of glue - applying, and reducing the waste of structural glue.
