To facilitate understanding, please refer to fig. 1, where fig. 1 is a schematic flowchart of a first embodiment of a method for generating an electronic cam data table according to an embodiment of the present application.

The above is a first embodiment of a method for generating an electronic cam data table provided in the embodiment of the present application, and the following is a second embodiment of the method for generating an electronic cam data table provided in the embodiment of the present application.
Referring to fig. 2, fig. 2 is a flowchart illustrating a second embodiment of a method for generating an electronic cam data table according to the present application.
In this embodiment, a method for generating an electronic cam data table includes:
The electronic cam data table generating method is applied to a winding machine, the corresponding triggering method in the application is that when the battery cell material on the winding machine is changed, namely when the battery cell material on the winding machine is changed, the model of the battery cell is considered to be changed, and at the moment, the battery cell material to be analyzed is determined based on the changed battery cell material.
The change of the cell material means that the model, the specification and the like of the cell material are changed, and the cell material is not changed for the conventional cell material supplement (that is, the used cell material is supplemented by the same cell material).
It should be noted that the cell material to be analyzed includes: anode sheet material, cathode sheet material, and separator material. It can be understood that the cell material wound on the winding machine also includes three types of anode sheet material, cathode sheet material and diaphragm material, and when at least one of the three types of materials is changed, the cell material is considered to be changed, and at this time, the changed cell material and the cell material which is not changed are both used as the cell material to be analyzed, that is, when only the cathode sheet material is changed, the changed cathode sheet material, the anode sheet material which is not changed and the diaphragm material are used as the cell material to be analyzed.
After the cell material to be analyzed is determined in step 201, the input thickness of the cell material to be analyzed is determined, and it can be understood that, since the cell material to be analyzed includes multiple cell materials, the input thickness corresponding to each cell material is also obtained at this time.
And step 203, acquiring the actual thickness of the battery cell material to be analyzed.
In order to ensure the accuracy of the material thickness of the battery cell material to be analyzed in this embodiment, the material thickness is determined by comparing the actual thickness with the input thickness, so that the actual thickness is determined while the input thickness of the battery cell material to be analyzed is determined.
It can be understood that the actual thickness can be obtained by actual calculation after the image of the battery cell material to be analyzed is shot by the camera; or the actual thicknesses corresponding to different cell materials may be stored in a storage module in the winding machine, and the corresponding actual thicknesses are directly retrieved through material signals of the cell materials during specific use.
And 204, judging whether the actual thickness is consistent with the input thickness, if so, taking the input thickness as the material thickness corresponding to the battery cell material to be analyzed, and if not, taking the actual thickness as the material thickness corresponding to the battery cell material to be analyzed.
Specifically, when the actual thickness is compared with the input thickness, if the actual thickness is consistent with the input thickness, the input thickness is used as the material thickness corresponding to the battery cell material to be analyzed, and if the actual thickness is inconsistent with the input thickness, the actual thickness is used as the material thickness corresponding to the battery cell material to be analyzed.
And 205, calculating the diameter increment of the single turn of the corresponding battery cell when the material is wound for one turn based on the thickness of the material corresponding to each material.
Specifically, in this embodiment, based on the material thickness corresponding to each material, calculating the diameter increase of a single turn of the corresponding battery cell when the material is wound for one turn may be:
calculating the diameter increment of a single circle of the corresponding battery cell to be 2d1 when the anode sheet material is wound for one circle based on the material thickness d1 corresponding to the anode sheet material;
calculating the diameter increment of a corresponding cell circle to be 2d2 when the cathode sheet material is wound for one circle based on the material thickness d2 corresponding to the cathode sheet material;
and calculating the diameter increment of the single circle of the corresponding battery cell to be 4d3 when the diaphragm material is wound for one circle based on the material thickness d3 corresponding to the diaphragm material.
It can be understood that each material in the cell material to be analyzed increases in thickness by two times after one winding when the cell material is single-layer, and the layer ratio of the anode sheet material, the cathode sheet material and the diaphragm material in the cell material to be analyzed is 1.
And step 206, determining the winding turns of each material in the cell material at different time.
In this embodiment, determining the number of winding turns of each material in the battery cell material at different times specifically includes:
determining initial winding angles corresponding to all materials in the battery cell materials to be analyzed;
obtaining rotation angles of all materials in the battery cell materials to be analyzed at different times;
and calculating the number of winding turns of each material at different time according to the initial winding angle and the rotation angle corresponding to each material in the materials to be analyzed.
Specifically, the number of winding turns N is = (rotational angle-initial winding angle)/360 °.
And step 207, calculating the winding diameter increment of each material in different time according to the winding turns and the single-turn diameter increment corresponding to each material.
After the diameter increase of a single turn of each material after one turn of winding and the number of turns of winding at different times are clarified, the increase of the winding diameter of each material at different times can be determined. For example, if the number of turns of the anode sheet material at time t1 is 2, the corresponding increase in winding diameter is: 2 x 2d1. It is understood that the increment of the winding diameter corresponding to the cathode sheet material and the separator material can be calculated by the foregoing example, and will not be described in detail in this embodiment.
And step 208, calculating the diameters of the battery cores at different times by integrating the diameters of the winding needles and the winding diameter increment of each material at different times.
After the winding diameter increment D1 corresponding to the anode sheet material, the winding diameter increment D2 corresponding to the cathode sheet material and the winding diameter increment D3 corresponding to the diaphragm material are determined at different times, the sum of the three is integrated to determine the total winding diameter increment, and the sum of the three and the diameter of the winding needle is added to obtain the cell diameters of the cells at different times.
And 209, acquiring the angular speed of the winding needle when the material to be analyzed is wound.
And step 210, calculating the linear speed of the winding needle corresponding to the diameter of each battery cell by using a first relational expression corresponding to the angular speed of the winding needle.
Wherein the first relational expression is:
winding needle angular velocity =360 ° × winding needle linear velocity/(cell actual diameter × pi).
And step 211, generating an electronic cam data table when the battery cell material to be analyzed is wound by combining the angular speed of the winding needle, the battery cell diameter at different time and the linear speed of the winding needle.
In this embodiment, when the electronic cam data table is generated, the material thickness of the material to be analyzed is determined, according to the material thickness, the increment of the single-turn diameter of the electric core of the material of the electric core to be analyzed when the material of the electric core is wound for one turn can be known, and based on the increment of the single-turn diameter, the diameters of the electric core at different times can be determined, then, the corresponding linear speed of the winding needle under different diameters of the electric core can be calculated based on the diameters of the electric core, so that the electronic cam data table when the material of the electric core to be analyzed is wound is generated.
