[0036] Embodiment 1

[0037] The present invention is described below in conjunction with preferred implementation steps. Figure 1 is a flow chart of a method for generating a battery cell tooling drawing according to the first embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0038] Step S101, establishing at least one battery cell tooling model and storing it in a target file path.

[0039] The method for generating battery cell tooling drawings provided in the first embodiment of the present application can be applied to the tooling development software for battery cells. The system constructs a tooling model library through the staff inputting necessary reference information such as project information, battery cell size information and battery cell tooling design, which includes tooling models, engineering drawings, product size constraint equations and other data. Finally, the system automatically modifies and outputs the battery cell tooling drawings, tooling version information history and other information.

[0040] In the first embodiment of the present invention, in order to improve the manufacturing efficiency of battery cells, it is necessary to establish corresponding tooling models (i.e., the tooling model of at least one of the above-mentioned battery cells) according to different blueprint battery cells, and distinguish the tooling model of each battery cell according to the file path, that is, the tooling model of each battery cell is placed in the file path under the target file path, to prepare for the subsequent work of manufacturing the battery cells.

[0041] Exemplarily, the battery cells can be classified into Class A and Class B. Class A includes battery cells A1 and A2, and Class B includes battery cells B1 and B2. The tooling model of battery cell A1 can be stored in the file path "C:\Batteries\Class A\Battery Cell A1", the tooling model of battery cell A2 can be stored in the file path "C:\Batteries\Class A\Battery Cell A2", the tooling model of battery cell B1 can be stored in the file path "C:\Batteries\Class B\Battery Cell B1", and the tooling model of battery cell B2 can be stored in the file path "C:\Batteries\Class B\Battery Cell B2".

[0042] Step S102, constructing a constraint relationship between variables in a tooling model of at least one battery cell, and storing the constraint relationship in a target file path.

[0043] In the first embodiment, it is necessary to obtain the constraint relationship between the variables in the tooling model of each battery cell, and store the constraint relationship involved in the tooling model of each battery cell in the target file path corresponding to the battery cell.

[0044] Step S103, when a modification instruction is detected, detecting whether a target processing instruction is triggered, wherein the modification instruction is an instruction to modify the data under the target file path, and the target processing instruction is a processing instruction initiated by the target object.

[0045] In the first embodiment, in order to automatically trigger the modification of the tooling model of the battery cell, it is necessary to detect whether the staff (i.e. the target object mentioned above, which can also be the developer, manager, etc.) modifies the size information of the model variable under the target file path, that is, to detect whether the above modification instruction is triggered. If the target object triggers the modification instruction, it is necessary to detect whether the target object triggers the instruction to restart the tooling development software, that is, the above target processing instruction.

[0046] Step S104, when the target processing instruction is detected, the tooling model under the target file path is modified, and a tooling drawing of at least one battery cell is generated according to the modified tooling model.

[0047] In the first embodiment, in order to improve the efficiency of generating battery cell tooling drawings, if it is detected that the target object triggers the target processing instruction, it is determined that the battery cell tooling model needs to be modified according to the modified size information of the target object, and after the automatic modification process of the battery cell tooling model is completed, at least one battery cell tooling drawing is generated according to the updated battery cell tooling model, thereby avoiding the problem of battery cell modification work flowing between multiple parties and reducing the manufacturing efficiency of battery cells.

[0048] In summary, the method for generating a battery cell tooling drawing provided in the first embodiment of the present application establishes a tooling model of at least one battery cell and stores it in a target file path; constructs a constraint relationship between variables in the tooling model of at least one battery cell, and stores the constraint relationship in the target file path; when a modification instruction is detected, detects whether a target processing instruction is triggered, wherein the modification instruction is an instruction to modify the data under the target file path, and the target processing instruction is a processing instruction initiated by the target object; when a target processing instruction is detected, the tooling model under the target file path is modified, and a tooling drawing of at least one battery cell is generated based on the modified tooling model, thereby solving the problem in the related art that, in the manufacturing process of batteries, the tooling drawings of the battery cells need to be changed multiple times when the battery design is changed, and the battery cell change process requires the participation of multiple parties, which reduces the battery manufacturing efficiency. By obtaining the constraint relationship between the tooling model and model variables of each battery cell and storing them in the target file path, the tooling models of all battery cells can be managed uniformly and conveniently and quickly, thereby improving the efficiency of performing related operations on the tooling models of the battery cells. At the same time, by automatically detecting whether the model variables in the target file path are modified by the target object, the tooling models of all battery cells can be automatically modified according to the detection results, thereby achieving the technical effect of intelligently generating battery cell tooling drawings, thereby improving the work efficiency of battery product replacement, and further achieving the effect of improving the manufacturing efficiency of battery cells.

[0049] Optionally, in the method for generating a battery cell tooling drawing provided in the first embodiment of the present application, a constraint relationship between variables in a tooling model of at least one battery cell is constructed, and the constraint relationship is stored in a target file path, including: determining a variable set for each tooling model in the tooling model of at least one battery cell; for each tooling model, determining the constraint relationship between each variable in the variable set to obtain the constraint relationship of each tooling model; creating a constraint file for each tooling model according to the constraint relationship of each tooling model; and storing the constraint file of each tooling model in the file path corresponding to each tooling model under the target file path.

[0050] In the first embodiment, in order to automatically generate a tooling model of a battery cell, model variables involved in the tooling model of at least one battery cell can be determined to obtain a variable set for each tooling model, wherein the model variables can be parameters of the external structure of the battery cell, such as the length, width, height or diameter, radius and other parameters of a component of the battery cell.

[0051] Then, the variables with associated relationships in the variable set of each tooling model are determined, and the constraint relationships between the variables with associated relationships are determined. It should be noted that the constraint relationships between model variables can be constraint relationships within the same model or between tooling models of different cells.

[0052] Finally, a new file is created based on the constraint relationship of each tooling model, and the constraint files of each tooling model are written into the newly created files to obtain the constraint files of each tooling model, and the constraint files of each tooling model are stored in the file path corresponding to each tooling model under the target file path. If there is a constraint relationship between the tooling models of two different battery cells, the constraint files of the tooling models of the two battery cells can be written into the constraint files of the tooling models of the two battery cells at the same time.

[0053] Optionally, in the method for generating a battery cell tooling drawing provided in Example 1 of the present application, the above-mentioned variable set includes at least one of the following types: a first type, a second type, and determining the constraint relationship between each variable in the variable set includes: determining a first constraint relationship when there is a relationship between the values ​​of at least two variables of the first type; determining the physical entities corresponding to the variables of the second type; determining a second constraint relationship when there is a relationship between the positions of at least two physical entities; and determining the constraint relationship between each variable in the variable set based on the first constraint relationship and the second constraint relationship.

[0054] In the first embodiment of the present invention, there are at least two types of constraint relationships between the model variables of the battery cell tooling model: one is the numerical relationship between the model variables (i.e., the first constraint relationship mentioned above), for example, the numerical value of the model variable C1 (i.e., the first type of variable mentioned above) needs to be greater than the numerical value of the model variable C2, or the numerical value of the model variable C1 needs to be less than the numerical value of the model variable C2, or the numerical value of the model variable C1 needs to be equal to the numerical value of the model variable C2; ​​the other is the relative position relationship between the model variables (i.e., the second constraint relationship mentioned above), for example, the distance between the battery cell component D1 (i.e., the physical entity corresponding to the second type of variable mentioned above) and the battery cell component D2 needs to be equal to (or less than, greater than) a preset numerical value.

[0055] Optionally, in the method for generating battery cell tooling drawings provided in Example 1 of the present application, the above-mentioned target file path includes at least one sub-file path, and a tooling model of at least one battery cell is established and stored in the target file path, including: determining the tooling template of the battery cell; determining the interface information of each battery cell in at least one battery cell; adjusting the tooling template according to the size information of each battery cell and the interface information of each battery cell, respectively, to obtain a tooling model of each battery cell, wherein the tooling model includes at least: a three-dimensional tooling model, an engineering drawing model, and a tooling template; and storing the tooling model of each battery cell in each sub-file path in at least one sub-file path.

[0056] In the first embodiment, in order to centrally manage all battery cell tooling models involved in the battery manufacturing process, at least one battery cell tooling model can be established based on the equipment structure of the battery cell tooling and the blueprint battery cell size in the actual production process and stored in the target file path.

[0057] Exemplarily, a template of a battery cell tooling model, i.e., the tooling template of the battery cell mentioned above, can be generated by three-dimensional drawing software, so that the tooling model of each battery cell in the actual production environment can be established according to the tooling template of the battery cell. The detailed size information of the model variables in the tooling model of each battery cell in at least one battery cell (i.e., the size information of each battery cell mentioned above) is determined respectively, and the interface information of the connection part between each battery cell and the tooling equipment is determined respectively. Then, the tooling template is adjusted according to the size information of each battery cell and the interface information of each battery cell respectively, and the value of the model variable of the tooling model is adjusted to obtain file data such as a three-dimensional tooling model, an engineering drawing model, and a tooling template, i.e., the tooling model of each battery cell mentioned above. Finally, according to the rule of storing a tooling model of a battery cell in each file path, the tooling model of each battery cell is stored in each sub-file path of at least one sub-file path under the target file path.

[0058] Optionally, in the method for generating a battery cell tooling drawing provided in the first embodiment of the present application, the at least one battery cell mentioned above includes a first battery cell, and the first battery cell represents a battery cell whose tooling structure is different from the tooling structure of the tooling template. Before adjusting the tooling template according to the size information of each battery cell and the interface information of each battery cell, the method also includes: establishing a tooling model of the first battery cell according to the tooling structure of the first battery cell and the size information of the first battery cell; creating a first file path, wherein the first file path is a file path different from the target file path; and storing the tooling model of the first battery cell in the first file path.

[0059] In the first embodiment of the present invention, when constructing each battery cell tooling model, for battery cells whose tooling structure varies greatly from the battery cell tooling template, simply changing the size information of the tooling model cannot meet the usage requirements of the battery cell. Therefore, the tooling model of the battery cell needs to be redesigned and placed in different folders.

[0060] In an optional embodiment, the first battery cell is a battery cell whose tooling structure is different from the tooling structure of the tooling template. For example, the first battery cell can be a battery cell on the same side of the pole or on the opposite side of the pole. When constructing the tooling model of the first battery cell, modeling can be performed directly in a three-dimensional mapping software based on the tooling structure of the first battery cell in the actual production environment, and the tooling model of the first battery cell is established based on the tooling structure of the first battery cell and the size information of the first battery cell. Then, a new model library is established, and a file path different from the target file path is created (i.e., the first file path mentioned above), and the tooling model of the first battery cell is stored in the first file path.

[0061] It should be noted that the first battery cell can include multiple types of battery cells. When storing tooling models of multiple types of battery cells, corresponding first file paths can be created according to the battery cell categories, and the working model of each type of first battery cell can be stored in the first file path corresponding to each type of first battery cell. Multiple file paths can also be created for the first file path corresponding to each type of first battery cell, which are used to store the tooling model of each first battery cell in the same type of first battery cell.

[0062] Optionally, in the method for generating a battery cell tooling drawing provided in Example 1 of the present application, before detecting whether to trigger a target processing instruction, the method further includes: triggering a modification instruction when a change in a variable value in a three-dimensional tooling model, or a change in a variable value in an engineering drawing model, or a change in a variable value in a tooling template, or a change in a variable value in a constraint relationship is detected.

[0063] In the first embodiment, in order to promptly respond to the staff's operation of modifying model variables and improve the efficiency and accuracy of generating the battery cell tooling drawing, it is necessary to trigger a modification instruction after the staff modifies the file under the target file path, thereby triggering the tooling development software to automatically modify the battery cell tooling model. Exemplarily, when the staff modifies the variable value in the three-dimensional tooling model under the target file path, or modifies the variable value in the engineering drawing model, or modifies the variable value in the tooling template, or modifies the variable value in the constraint relationship, the modification instruction will be triggered.

[0064] Optionally, in the method for generating a battery cell tooling drawing provided in Example 1 of the present application, the tooling model under the target file path is modified, including: determining a first file based on a modification instruction, wherein the first file is a file that has been modified under the target file path; determining a second file based on a constraint relationship, wherein a constraint relationship exists between model variables in the second file and model variables in the first file; and modifying the tooling model under the target file path based on the first file, the constraint relationship, and the second file.

[0065] In the first embodiment, in order to improve the generation efficiency of the battery cell tooling drawing, when it is detected that the staff has restarted the tooling development software, the model file modified by the staff (i.e., the first file mentioned above) can be determined according to the modification instruction, and the first variable that has a constraint relationship with the model variable in the first file can be determined according to the constraint relationship, and then the file to which the first variable belongs (i.e., the second file mentioned above) can be determined. Finally, the variable values ​​of the model variables in the first file are calculated according to the constraint relationship in the constraint file to obtain the variable values ​​of the model variables in the second file, and the second file is modified according to the calculated variable values ​​of the model variables in the second file to obtain a new tooling model, including: a blueprint 3D tooling model, an engineering drawing model, a PDF template file, a constraint equation file, etc.

[0066] In an optional embodiment, the second variable modified in the model file modified by the staff can be determined according to the modification instruction, and the third variable that has a constraint relationship with the second variable can be determined according to the constraint relationship.
