Description

Technical Field

[0001] The present application relates to the field of battery processing technology, and in particular to an energy storage module production system, method, storage medium and program product. Background Art

[0002] When producing energy storage modules, one production line can only produce a single type of module, and cannot produce multiple types of module products at the same time. As an example, a single battery pack has two different types of modules to be assembled. In this case, the module manufacturer can only use two production lines to produce two different types of modules at the same time, and then assemble them. This production logic also increases the difficulty of production line management. It is necessary to ensure that the two production lines are in sync, otherwise there will be too much stacking of semi-finished products on the production line, and it will also increase the manpower for module transportation. The above combined increases the production and manufacturing costs.

[0003] Based on this, the present application provides an energy storage module production system, method, storage medium and program product to improve the existing technology and meet the needs of practical applications. Summary of the invention

[0004] The purpose of this application is to provide an energy storage module production system, method, storage medium and program product, which solves the problem of high production and manufacturing costs for assembling modules of various different models.

[0005] The purpose of this application is achieved by the following technical solutions:

[0006] In a first aspect, the present application provides an energy storage module production system, the energy storage module production system is used for the production of battery packs, and the energy storage module production system includes:

[0007] A conveyor production line, wherein the conveyor production line includes a material preparation station, a battery cell loading station, a module stacking station, a module extrusion station and a box entry inspection station arranged in sequence according to a production route;

[0008] A clamping and shifting device, wherein the clamping and shifting device is arranged on the production route of the conveying production line;

[0009] An extrusion device, the extrusion device is arranged at the module extrusion station;

[0010] The energy storage module production system further includes: a visual inspection device and a controller, wherein the controller is electrically connected to the conveying production line, the clamping and shifting device, and the visual inspection device, respectively, and the controller is configured to:

[0011] Acquire a battery pack parameter set of a battery pack, wherein the battery pack parameter set includes module information of each battery module in the battery pack;

[0012] The total number of cells of the battery pack is obtained according to the battery pack parameter set, and when the number of cells to be produced at the material preparation station is not less than the total number of cells, the clamping and shifting device is controlled to transfer each cell to be produced to the cell loading station according to the arrangement order of the battery modules;

[0013] The stacking of each battery module is realized at the module stacking station; the extrusion of each battery module is realized at the module extrusion station; when each battery module has completed the extrusion, the clamping and shifting device is controlled to move each battery module to the liquid cooling plate space of the box entry detection station to realize the box entry operation, and the actual position information of each battery module is obtained by using the visual acquisition device;

[0014] The actual position information is compared with the pre-acquired reference position information to determine whether the battery module in the battery pack is offset; when the determination result is offset, an alarm is issued using an alarm device.

[0015] The beneficial effect of the present technical solution is that the controller obtains a battery pack parameter set including module information to control the operation of the production line. When the number of battery cells at the preparation station meets the production requirements, the controller instructs the clamping and shifting device to transfer the battery cells to the battery cell loading station. At the module stacking station, the battery cells are assembled into modules. Subsequently, the modules are transferred to the module extrusion station for extrusion. After the extrusion is completed, the module is moved to the box entry inspection station for box entry. The visual inspection device obtains the actual position information of the module at this station, and compares it with the reference position information to detect whether the module is offset. If the module position offset exceeds the preset range, the controller triggers the alarm device to prompt the operator to intervene.

[0016] Therefore, through the automated conveying production line and clamping and shifting device, manual operations are reduced and production efficiency is improved. Visual inspection and position comparison ensure the correct assembly and position of the module, reducing production defects. It can handle battery packs containing modules of different models, realize the cyclic production of multiple modules, and improve the flexibility and adaptability of the production line. The energy storage module production system uses the battery pack parameter set to produce according to the battery pack as a unit, and cyclically produces multiple different types of battery modules in the battery pack. There is no need to consider the rhythm of multiple production lines, which reduces the difficulty of production line management. At the same time, it will also avoid the manpower of module transportation and reduce production costs.

[0017] In some possible implementations, the controller is configured to implement stacking and squeezing of the battery modules in the following manner:

[0018] The clamping and shifting device is controlled to sequentially transfer a corresponding number of battery cells to the stacking station for module stacking according to the arrangement order of each battery module in the module information, and after any battery module is stacked, it is transferred to the module extrusion station, and the extrusion device is controlled to extrude it.

[0019] The beneficial effect of this technical solution is that the automated stacking and extrusion process reduces manual operations, significantly improves production efficiency and production line throughput, and can flexibly adjust the production process according to module information to adapt to the production of battery modules of different models and configurations.

[0020] In some possible implementations, the battery pack is composed of two battery modules of different specifications, namely a first module and a second module; the module information includes the number of the first modules, the number of the second modules, the number of battery cells in the first module, the number of battery cells in the second module, the insulation requirements of the battery cell surface, and the arrangement order of each battery module in the battery pack.

[0021] The beneficial effect of this technical solution is that, through accurate module information and automated control, the accuracy of cell stacking and module arrangement is ensured, and the production accuracy of battery packs is improved. The production line can be flexibly adjusted according to the module information to meet the production needs of modules of different specifications, thus improving the adaptability and flexibility of the production line.

[0022] In summary, this technical solution achieves high efficiency, high precision and high reliability in the production of battery packs consisting of two battery modules of different specifications by integrating detailed module information and automated control.

[0023] In some possible implementations, the battery pack is composed of a plurality of first modules arranged side by side and a second module arranged adjacent to each first module; a tooling plate is provided on the battery cell loading station, and the tooling plate is used to place the battery pack for boxing operation; the controller is configured to compare the actual position information with the pre-acquired reference position information in the following manner to determine whether the battery module in the battery pack is offset:

[0024] Based on the 3D digital model of the battery pack and the tooling board information, the battery pack and the tooling board are simulated and combined to obtain a first reference position area and a second reference position area as reference position information;

[0025] Using the visual acquisition device to obtain a first actual location area where all first modules are located, and a second actual location area where all second modules are located, and using the first actual location area and the second actual location area as actual location information;

[0026] The actual position information is compared with the pre-acquired reference position information to determine whether the battery module in the battery pack is offset.

[0027] The beneficial effects of this technical solution are that real-time position detection and comparison enhance the control of product quality and help identify and correct deviations in the production process. Automated visual inspection reduces reliance on manual inspection and improves inspection speed and consistency. By combining 3D digital modeling, tooling board simulation combination and visual acquisition technology, precise control and quality assurance of battery module position are achieved, improving production efficiency and product quality.

[0028] In some possible implementations, the controller is configured to compare the actual position information with the pre-acquired reference position information in the following manner to determine whether the battery module in the battery pack is offset:

[0033] The beneficial effect of this technical solution is that through two-level offset calculation and judgment, the accuracy of module position detection is improved to ensure the correct installation of the module. Automated position comparison and offset judgment reduce the need for manual inspection and improve production efficiency. Rapid position detection and judgment reduce downtime in production and improve the overall efficiency of the production line.

[0037] Determining the second reference position area according to the second preset coordinate distance value between each of the first modules and each of the second modules;

[0038] The first reference location area and the second reference location area are used as reference location information.

[0039] The beneficial effect of this technical solution is that by using the reference points on the tooling plate and the preset coordinate distance values, the accuracy of module positioning is improved to ensure the accuracy of module installation. The reference position area setting enhances the control of the battery module installation quality and helps to improve the overall performance and reliability of the battery pack. Automated position area determination reduces the need for manual inspection and adjustment and improves production efficiency. Rapid reference position area determination and subsequent actual position comparison reduce downtime in production and improve the overall efficiency of the production line.

[0041] The controller is also configured to:

[0042] According to the insulation requirements of the battery cell surface, the battery cells meeting the total number of battery cells of the battery pack at the battery cell loading station are transferred to the insulating sheet installation station by using the clamping and shifting device;

[0043] The indicator lights of the auxiliary indicator device are controlled to indicate the surface insulation requirements of the corresponding battery cells, wherein the light is off to indicate that the surface of the battery cell is not treated, and the light is on to indicate that an insulating sheet is attached to the surface of the battery cell;

[0044] When the corresponding insulating sheets of each of the battery cells have been attached, the clamping and shifting device is used to transfer them to the module stacking station.

[0045] The beneficial effect of this technical solution is that the auxiliary indicator device ensures that the insulation treatment of each battery cell is carried out as required, thereby improving the accuracy and consistency of the insulation treatment. The intuitive indication of the indicator light reduces the operator's human errors during the insulation treatment process, such as missing or wrongly pasting the insulation sheet. The automated battery cell transmission and intuitive indication system reduce the operation time and improve the overall production efficiency.

[0062] System Embodiments.

[0063] See also Figure 1 , Figure 1 It is a structural schematic diagram of an energy storage module production system provided in an embodiment of the present application.

[0064] The energy storage module production system is used for the production of battery packs, and the energy storage module production system comprises:

[0065] A conveyor production line, wherein the conveyor production line includes a material preparation station, a battery cell loading station, a module stacking station, a module extrusion station and a box entry inspection station arranged in sequence according to a production route;

[0066] A clamping and shifting device, wherein the clamping and shifting device is arranged on the production route of the conveying production line;

[0067] An extrusion device, the extrusion device is arranged at the module extrusion station;

[0068] The energy storage module production system further includes: a visual inspection device and a controller, wherein the controller is electrically connected to the conveying production line, the clamping and shifting device, and the visual inspection device, respectively, and the controller is configured to:

[0069] Acquire a battery pack parameter set of a battery pack, wherein the battery pack parameter set includes module information of each battery module in the battery pack;

[0070] The total number of cells of the battery pack is obtained according to the battery pack parameter set, and when the number of cells to be produced at the material preparation station is not less than the total number of cells, the clamping and shifting device is controlled to transfer each cell to be produced to the cell loading station according to the arrangement order of the battery modules;

[0071] The stacking of each battery module is realized at the module stacking station; the extrusion of each battery module is realized at the module extrusion station; when each battery module has completed the extrusion, the clamping and shifting device is controlled to move each battery module to the liquid cooling plate space of the box entry detection station to realize the box entry operation, and the actual position information of each battery module is obtained by using the visual acquisition device;

[0072] The actual position information is compared with the pre-acquired reference position information to determine whether the battery module in the battery pack is offset; if the determination result is offset, an alarm is issued using an alarm device, such as an audible and visual alarm lamp.

[0073] The production line is set up according to the established production sequence, including multiple stations including material preparation station, battery cell loading station, module stacking station, module extrusion station and box inspection station. The stations work together to complete the entire production process from raw material preparation to final product inspection. The clamping and shifting device is set on the conveying production line to move the battery cell from one station to another to ensure that the battery cell is processed according to the established production route. The extrusion device is located at the module extrusion station and is used to extrude the battery module to fix the battery cell and form a structurally stable module. The controller is responsible for coordinating all operations on the production line, is connected to the conveying production line, the clamping and shifting device and the visual inspection device, and is configured with specific control logic.

[0074] The module information includes the number of battery cells in each battery module, the insulation requirements on the surface of each battery cell, and the arrangement order of the battery modules in the battery pack.

[0075] Specifically, the controller obtains a battery pack parameter set including module information and controls the operation of the production line. When the number of battery cells at the preparation station meets the production requirements, the controller instructs the clamping and shifting device to transfer the battery cells to the battery cell loading station. At the module stacking station, the battery cells are assembled into modules. Subsequently, the modules are transferred to the module extrusion station for extrusion. After the extrusion is completed, the module is moved to the box entry inspection station for box entry. The visual inspection device obtains the actual position information of the module at this station and compares it with the reference position information to detect whether the module is offset. If the module position offset exceeds the preset range, the controller triggers the alarm device to prompt the operator to intervene.

[0076] The advantage of this embodiment is that, through the automated conveying production line and clamping and shifting device, manual operations are reduced and production efficiency is improved. Visual inspection and position comparison ensure the correct assembly and position of the module, reducing production defects. It is able to handle battery packs containing modules of different models, realize the cyclic production of multiple modules, and improve the flexibility and adaptability of the production line. The energy storage module production system uses the battery pack parameter set to produce according to the battery pack as a unit, and cyclically produces multiple different types of battery modules in the battery pack, without having to consider the rhythm of multiple production lines, reducing the difficulty of production line management, while also avoiding the manpower of module transportation and reducing production costs.

[0077] In specific applications, each single-machine equipment (such as a clamping and shifting device, an extrusion device and a welding machine, which is used to weld the connecting plates or the tabs of the battery cells together to ensure that the electrical connection between the battery cells in the module is reliable and stable) automatically calls different programs to produce different modules, thereby solving the problem of producing different types of battery modules of a battery pack on the same production line at the same time, reducing the manpower wasted in module transportation and the risk of module mixing.

[0078] In a specific application, the gripping and shifting device may include a plurality of vacuum suction cups for handling the battery cells without damage, and moving the battery cells from one place to another by suction. It may also include a plurality of manipulators with multiple degrees of freedom for handling and positioning the battery cells in multiple directions.

[0079] In some embodiments, the controller is configured to implement stacking and squeezing of the battery modules in the following manner:

[0080] The clamping and shifting device is controlled to sequentially transfer a corresponding number of battery cells to the stacking station for module stacking according to the arrangement order of each battery module in the module information, and after any battery module is stacked, it is transferred to the module extrusion station, and the extrusion device is controlled to extrude it.

[0081] Specifically, the controller first obtains the module information of each battery module from the battery pack parameter set, including the arrangement order between the battery modules and the number of battery cells required for each battery module. According to the module information, the controller instructs the clamping and shifting device to sequentially transfer the corresponding number of battery cells to the stacking station. At the stacking station, the battery cells are stacked according to a predetermined arrangement order and structure to form a battery module. After the stacking is completed, the clamping and shifting device transfers each battery module to the module extrusion station. The controller synchronously controls the extrusion device to extrude each battery module according to preset parameters to fix the battery cells and form a module with a stable structure.

[0082] The advantage of this embodiment is that the automated stacking and extrusion process reduces manual operations, significantly improves production efficiency and production line throughput, and can flexibly adjust the production process according to module information to adapt to the production of battery modules of different models and configurations.

[0083] In some embodiments, the battery pack is composed of two battery modules of different specifications, namely a first module and a second module; the module information includes the number of the first modules, the number of the second modules, the number of battery cells in the first module, the number of battery cells in the second module, the insulation requirements of the battery cell surface and the arrangement order of each battery module in the battery pack.

[0084] According to the integrated module information, the controller automatically guides the production line to produce battery modules. The production process of battery modules includes controlling the clamping and shifting device to sequentially transfer the corresponding number of battery cells to the production station according to the arrangement order and quantity requirements in the module information. For example, at the stacking station, the battery cells are precisely stacked according to the quantity and arrangement order specified in the module information to form a plurality of first modules and second modules. At the same time, according to the insulation requirements in the module information, the surface of the battery cells can be insulated accordingly to ensure the safety and functionality of the battery module. The stacked modules are transferred to the extrusion station, and the controller guides the extrusion device to extrude the modules to fix the battery cells and form a structurally stable module.

[0085] The advantage of this embodiment is that accurate module information and automated control ensure the accuracy of cell stacking and module arrangement, thereby improving the production accuracy of battery packs. The production line can be flexibly adjusted according to the module information to meet the production needs of modules of different specifications, thereby improving the adaptability and flexibility of the production line.

[0086] In summary, this technical solution achieves high efficiency, high precision and high reliability in the production of battery packs consisting of two battery modules of different specifications by integrating detailed module information and automated control.

[0087] In some embodiments, the battery pack is composed of a plurality of first modules arranged side by side and a second module arranged adjacent to each first module; a tooling plate is provided on the battery cell loading station, and the tooling plate is used to place the battery pack for boxing operation; the controller is configured to compare the actual position information with the pre-acquired reference position information in the following manner to determine whether the battery module in the battery pack is offset:

[0088] Based on the 3D digital model of the battery pack and the tooling board information, the battery pack and the tooling board are simulated and combined to obtain a first reference position area and a second reference position area as reference position information;

[0089] Using the visual acquisition device to obtain a first actual location area where all first modules are located, and a second actual location area where all second modules are located, and using the first actual location area and the second actual location area as actual location information;

[0090] The actual position information is compared with the pre-acquired reference position information to determine whether the battery module in the battery pack is offset. 3D digital model is a three-dimensional model created using digital technology, which can describe in detail the geometric shape, size, structure and performance of an object. Tooling board information includes, for example: the geometric dimensions of the tooling board, the length, width, and height of the tooling board, as well as special shapes or contours to ensure that the battery pack is correctly placed on the tooling board; positioning feature points (MARK points), the coordinates of fixed points or feature points for precise positioning, used as a reference in the simulation combination to help determine the exact position of the module on the tooling board; surface features of the tooling board, texture and flatness features of the tooling board surface.

[0091] The battery pack is composed of multiple battery modules, and the multiple battery modules are placed in the liquid cooling plate space composed of the liquid cooling plate of the battery pack, and then the battery pack is placed on the tooling plate. In the related technology, when the product is changed, the actual assembly of the real object is required to adjust the equipment parameters and structure. A product is actually assembled as a standard template for change, and compared with this standard template during mass production. The actual assembled product itself has a certain deviation from the ideal size, and there will be a big difference when it is used as a standard template. This is because the actual assembled product is used as a standard template, and the tolerance cannot meet the deviation during mass production. The battery packs finally produced are prone to poor welding and low equipment utilization rate. In other words, when the product is changed, it can only be carried out by using the real object as a standard template, and the equipment parameters and position cannot be adjusted without the real object.

[0092] In this embodiment, the 3D digital model of the battery pack is used to simulate and combine with the tooling board to obtain digital model information, and the expected position area of ​​the first module and the second module is obtained through the digital model information for subsequent actual position comparison. This process avoids the deviation of the standard template made by the physical object. When the product (battery pack) is changed, it is not necessary to use the physical object as the standard template. As long as the 3D digital model of the battery pack is used to simulate and combine with the tooling board, the parameters and position of the tooling board can be adjusted when there is no physical object. Through the simulation combination, the first reference position area and the second reference position area are determined. The reference position area represents the position that each first module and the second module should occupy under ideal conditions. Use a visual acquisition device (such as a camera) to obtain the first actual position area where all first modules are located, and the second actual position area where all second modules are located. Since the actual position information is obtained in real time by the visual acquisition device, it reflects the actual placement position of the battery module. The actual position information is compared with the reference position information obtained in advance to determine whether the battery module has shifted. It can be considered that any deviation between the actual position and the reference position will be identified. If the comparison results show that the module position deviation exceeds the preset tolerance range, the alarm mechanism is triggered to prompt the operator to intervene.

[0093] The benefit of this embodiment is that real-time position detection and comparison enhances the control of product quality and helps to identify and correct deviations in the production process. Automated visual inspection reduces the reliance on manual inspection and improves inspection speed and consistency. By combining 3D digital modeling, tooling board simulation combination and visual acquisition technology, precise control and quality assurance of battery module position are achieved, improving production efficiency and product quality.

[0094] In some embodiments, the controller is configured to compare the actual position information with the pre-acquired reference position information to determine whether the battery module in the battery pack is offset in the following manner:

[0095] Acquire a first actual offset according to the first reference position area and the first actual position area;

[0096] When the first actual offset is within its corresponding offset control range, acquiring a second actual offset according to the second reference position area and the second actual position area;

[0097] When the first actual offset is not within the corresponding offset control range, the judgment result is considered to be offset;

[0098] When the second actual offset is within the corresponding offset control range, the judgment result is considered to be no offset; otherwise, the judgment result is considered to be offset.

[0099] First, according to the first reference position area and the first actual position area of ​​the first module, the first actual offset is calculated to represent the overall difference between the actual position of the first module and the expected position. Check whether the first actual offset is within the preset offset control range. The control range can be considered to be the maximum allowable deviation, which is set based on the tolerance requirements of module installation. If the first actual offset is within the control range, the second actual offset is calculated according to the second reference position area and the second actual position area of ​​the second module. Check whether the second actual offset is within the corresponding offset control range. If the second actual offset is also within the control range, it is considered that there is no offset; if it is not within the control range, it is considered that an offset has occurred. If the first actual offset is not within the control range, the second actual offset will not be calculated, saving the calculation process and directly judging that an offset has occurred. Based on the above judgment, the controller will draw a conclusion on whether the module is offset. If the judgment result is an offset, the controller can trigger an alarm or instruct the device to adjust.

[0100] The advantage of this embodiment is that the accuracy of module position detection is improved through two-level offset calculation and judgment, ensuring that the module is correctly installed. Automated position comparison and offset judgment reduce the need for manual inspection and improve production efficiency. Rapid position detection and judgment reduce downtime in production and improve the overall efficiency of the production line.

[0101] As an example, a simulated combination of a 3D digital model of a battery pack and a tooling board is used to determine the ideal or reference position area of ​​the first module, which can be specifically defined by a coordinate system in the 3D digital model. A visual sensor is used to obtain the actual position area of ​​the first module and provide the actual coordinates of the battery module on the tooling board. Data synchronization and reference points are used to ensure that the data obtained from the 3D digital model and the visual acquisition device are in the same coordinate system for accurate comparison. The feature points of the actual module are identified by image processing technology and matched with the corresponding feature points in the 3D digital model. The calculation of the offset includes: extracting the expected coordinates from the first reference position area and extracting the actual coordinates from the first actual position area. The deviation between the actual position and the expected position is determined by mathematical calculations (such as vector subtraction). The calculated offset is compared with a preset tolerance range to determine whether it is within an acceptable offset range. The second actual offset can be obtained according to the second reference position area and the second actual position area. The method of obtaining the first actual offset can be referred to, and no further details will be given.

[0102] In another embodiment, different from the previous embodiment, a first actual offset is obtained based on the first reference position area and the first actual position area; then a second actual offset is obtained based on the second reference position area and the second actual position area; a total actual offset is obtained based on the first actual offset and the second actual offset; when the total actual offset is within its corresponding offset control range, the judgment result is considered to be no offset; otherwise, the judgment result is considered to be an offset.

[0103] Obtaining the total actual offset according to the first actual offset and the second actual offset may be to take the sum of the first actual offset and the second actual offset as the total actual offset, compare the total actual offset with a preset offset control range, and if the total actual offset is within the control range, it is considered that the module has no offset. If the total actual offset exceeds the control range, it is considered that the module has offset.

[0104] In some embodiments, the controller is configured to obtain the reference position information in the following manner:

[0105] Using at least one characteristic point preset in the tooling plate as a reference point;

[0106] Determining a first reference position area according to a first preset coordinate distance value between the reference point and each of the first modules;

[0107] Determining the second reference position area according to the second preset coordinate distance value between each of the first modules and each of the second modules;

[0108] The first reference location area and the second reference location area are used as reference location information.

[0109] One or more feature points preset on the tooling board are used as reference points. The reference point is a fixed position on the tooling board for positioning and reference, which is used to ensure the accuracy of the entire module installation process. The feature point can be a bump or concave hole pre-set on the tooling board, preferably 4, respectively set at the four corners of the tooling board. It can also be 1, 2 or 3, respectively set at a corner or side of the tooling board. According to the first preset coordinate distance value between the reference point and the first module, the controller determines the reference position area of ​​the first module. The first preset coordinate distance value is pre-set based on the module design and the tooling board layout. Similarly, according to the second preset coordinate distance value between the first module and the second module, the reference position area of ​​the second module is determined, ensuring that the relative position between the modules is also accurately controlled. The first reference position area and the second reference position area (coordinates) are integrated to form complete reference position information for subsequent actual position comparison.

[0110] The benefit of this embodiment is that by using the reference points on the tooling board and the preset coordinate distance values, the accuracy of module positioning is improved, ensuring the accuracy of module installation. The reference position area setting enhances the control of the battery module installation quality and helps to improve the overall performance and reliability of the battery pack. Automated position area determination reduces the need for manual inspection and adjustment and improves production efficiency. Rapid reference position area determination and subsequent actual position comparison reduce downtime in production and improve the overall efficiency of the production line.

[0111] For easier understanding, see Figure 3 and Figure 4 , Figure 3 is a structural schematic diagram of a tooling plate provided in an embodiment of the present application, Figure 4 It is a structural schematic diagram of a clamping block provided in an embodiment of the present application.

[0112] The tooling plate includes a tooling table, a first fixed block and a second fixed block arranged at both ends of the tooling table along the length direction of the tooling table. And a plurality of third fixed blocks and a plurality of clamping blocks are arranged at both ends along the width direction of the tooling table, and the clamping blocks can be extended and retracted along the width direction of the tooling table. At the same time, a slide groove can be set in the length direction of the tooling table, and the first fixed block or the second fixed block is set on the slide groove and can be moved along the length direction of the tooling table. The movement of the clamping block and the fixed block can adapt to battery packs of different sizes. Among them, the characteristic points can be protrusions or recessed holes pre-set at both ends of the first fixed block and the second fixed block of the tooling plate, respectively, to provide four characteristic points.

[0113] In some embodiments, an insulating sheet installation station is further included between the battery cell loading station and the module stacking station; the insulating sheet installation station includes an auxiliary indicator device, and the auxiliary indicator device includes a plurality of indicator lights corresponding to the battery cells respectively arranged at the insulating sheet installation station; the controller is further configured to:

[0114] According to the insulation requirements of the battery cell surface, the battery cells meeting the total number of battery cells of the battery pack at the battery cell loading station are transferred to the insulating sheet installation station by using the clamping and shifting device;

[0115] The indicator lights of the auxiliary indicator device are controlled to indicate the surface insulation requirements of the corresponding battery cells, wherein the light is off to indicate that the surface of the battery cell is not treated, and the light is on to indicate that an insulating sheet is attached to the surface of the battery cell;

[0116] When the corresponding insulating sheets of each of the battery cells have been attached, the clamping and shifting device is used to transfer them to the module stacking station.

[0117] An insulating sheet installation station is set between the battery cell loading station and the module stacking station, which is responsible for installing the insulating sheet according to the insulation requirements of the battery cell. It can be understood that an auxiliary indication device is provided on the insulating sheet installation station, including multiple indicator lights, each indicator light corresponds to a battery cell, which is used to indicate the surface insulation requirements of the battery cell. According to the total number of battery cells required for the battery pack, the battery cell is transferred from the battery cell loading station to the insulating sheet installation station by using a clamping and shifting device. The indicator light of the auxiliary indication device is controlled according to the insulation requirements of the battery cell surface. If the light is off, it means that the surface of the battery cell does not need to be processed, and if the light is on, it means that an insulating sheet needs to be attached to the surface of the battery cell. Specifically, the light can also include constant light and flashing, and different lighting modes are used to indicate different types of insulating sheet installation requirements. The operator can perform corresponding insulation treatment on the battery cell according to the instructions of the indicator light. Once all the batteries have completed the attachment of the insulating sheet, the clamping and shifting device transfers them to the module stacking station.

[0118] The advantage of this embodiment is that the auxiliary indicator device ensures that the insulation treatment of each battery cell is carried out as required, thereby improving the accuracy and consistency of the insulation treatment. The intuitive indication of the indicator light reduces the operator's human error during the insulation treatment process, such as missing or wrongly pasting the insulation sheet. The automated battery cell transmission and intuitive indication system reduce the operation time and improve the overall production efficiency.
