Description

Technical Field

[0001] The present application relates to the field of cylindrical battery grooving, and particularly to a cylindrical battery grooving adjustment method, an electronic device, and a computer-readable storage medium. Background Art

[0002] Cylindrical batteries are generally divided into laser sealing and mechanical sealing. In the mechanical sealing process, the grooving process before sealing is particularly crucial and plays a role in determining the compliance of the semi-finished product structure before sealing. Therefore, the grooving process is a key process that needs to be strictly controlled in battery assembly. However, when adjusting its process parameters, a slight change will affect the whole, and the process window is small and there are many change factors, making the grooving adjustment process of cylindrical batteries relatively complex and the adjustment efficiency of the grooving process relatively low. Summary of the Invention

[0003] The purpose of the present application is to provide a cylindrical battery grooving adjustment method, which can solve the technical problem that when adjusting the process parameters of the cylindrical battery grooving process, a slight change will affect the whole, and there are many change factors, making the grooving adjustment process of cylindrical batteries relatively complex.

[0004] To achieve the above purpose, the present application provides a cylindrical battery grooving adjustment method, including: S1. Determine the grooving processing profile of the battery, and sequentially divide the housing of the battery into a core accommodating part, a grooving part, and a shell mouth part in a first direction; the core accommodating part is used to accommodate the core of the battery, the side wall of the grooving part is formed with a groove by a grooving tool, the shell mouth part is used to fix the cover plate of the battery, and a sealing ring for sealing the shell mouth part is sleeved on the cover plate; S2. Judge whether the deformation amount of the insulating sheet of the core is within a first preset range. If so, determine the length of the core accommodating part in the first direction and the feed amount of the grooving tool, and execute step S3; S3. Judge whether the difference between the thickness of the sealing ring and the length of the shell mouth part in the first direction is within a second preset range. If so, determine the length of the shell mouth part in the first direction.

[0005] Compared with the prior art, in this application, by determining the grooving processing profile of the battery, it is judged whether the deformation amount of the insulating sheet of the core is within the first preset range. If so, the length of the core accommodating part in the first direction and the feed amount of the hob are determined; it is judged whether the difference between the thickness of the sealing ring and the length of the shell opening part in the first direction is within the second preset range. If so, the length of the shell opening part in the first direction is determined. By first determining the length of the core accommodating part in the first direction and the feed amount of the hob, and then determining the length of the shell opening part in the first direction, that is, by first orderly determining some of the change factors of the cylindrical battery and then adjusting other change factors, it is possible to avoid the situation where a single adjustment in the grooving process affects the whole, simplify the grooving adjustment process of the cylindrical battery, and improve the adjustment efficiency of the grooving process. And because when adjusting some of the parameters, there is no need to pay attention to other parameters, it is possible to concentrate on the adjustment, thus effectively dealing with the problem of the small process window of the grooving adjustment process.

[0006] Optionally, before the step S2, it further includes: Initializing the length of the core accommodating part in the first direction according to the length of the core in the first direction, the thickness of the bottom wall of the housing, and the thickness of the side wall of the housing.

[0007] Optionally, the initial value of the length of the core accommodating part in the first direction is equal to the sum of the length of the core of the battery in the first direction, the thickness of the bottom wall of the housing, and the thickness of the side wall of the housing.

[0008] Optionally, the judgment of whether the deformation amount of the insulating sheet of the core is within the first preset range further includes: If the judgment result is negative, adjust the processing position of the hob on the housing in the first direction to adjust the length of the core accommodating part in the first direction, adjust the feed amount of the hob, and re-execute the step S2.

[0009] Optionally, when the deformation amount of the insulating sheet is less than the lower limit of the first preset range, reduce the length of the core accommodating part in the first direction and increase the feed amount of the hob; Optionally, when the deformation amount of the insulating sheet is greater than the upper limit of the first preset range, increase the length of the core accommodating part in the first direction and reduce the feed amount of the hob.

[0010] Optionally, the deformation amount of the insulating sheet of the core is obtained by analyzing the cross-section of the battery intercepted in the first direction.

[0012] Optionally, before the step S3, it further includes: Initialize the length of the housing opening in the first direction, and the initial value of the housing opening is equal to the length of the battery cover plate in the first direction.

[0019] To describe in detail the technical content, structural features, achieved objects and effects of the present application, the following is described in detail in conjunction with the embodiments and with reference to the drawings.

[0020] Please refer to Figure 1 And Figure 2 , the present application discloses a cylindrical battery rolling groove adjustment method, including: Step S1: Determine the grooving processing profile of the battery. The housing 1 of the battery is sequentially divided into a core accommodating portion 11, a grooving portion 12, and a housing opening portion 13 in the first direction. The core accommodating portion 11 is used to accommodate the battery core 2. The side wall of the grooving portion 12 is formed with a groove 121 by a hob. The housing opening portion 13 is used to fix the battery cover plate 4, and a sealing ring 5 for sealing the housing opening portion 13 is sleeved on the cover plate 4. Among them, the grooving portion 12 is the transition area between the core accommodating portion 11 and the housing opening portion 13, which plays a role in adjusting the process window and is used to control the length of the battery in the first direction when the battery is caulked after sealing. When the hob processes the battery, the groove width of the groove 121 can be adjusted by adjusting the width of the cutter face of the hob and the feed amount of the hob (i.e., the depth at which the hob cuts into the housing 1).

[0021] When the hob processes the battery, the housing 1 will be extruded by the hob, and part of the side wall of the housing 1 will be pressed into the groove by the hob. The length of the housing 1 in the first direction will be reduced, and the reduced length is approximately equal to twice the feed amount of the hob. Therefore, the length of the housing 1 in the first direction before grooving is:

[0022] Among them, is the length of the housing 1 in the first direction after processing, is the length of the housing opening portion 13 in the first direction, is the groove width of the groove 121, is the feed amount of the hob, is the length of the core accommodating portion 11 in the first direction. Thus, in the process of adjusting the groove, the above parameters are all determined, and the radius of the housing is fixed, so the basic shape of the housing can also be determined.

[0023] Therefore, when the length of the core accommodating portion 11 in the first direction, the feed amount of the hob, and the length of the housing opening portion 13 in the first direction are determined, the position of the groove 121, the groove width of the groove 121, and the length of the housing in the first direction before processing can be determined. At this time, the grooving processing of the battery can be formally carried out.

[0024] It should be noted that in this application, the first direction refers to the axial direction of the cylindrical battery.

[0025] Step S2: Determine whether the deformation of the insulating sheet 3 on the bobbin 2 (provided at one end of the bobbin 2 away from the bottom wall of the housing 1) is within the first preset range. If so, determine the length of the bobbin accommodating portion 11 in the first direction and the feed amount of the hob, and execute Step S3. When the hob processes the battery, the housing 1 will be extruded by the hob, and its length in the first direction will decrease. At this time, the insulating sheet 3 of the bobbin 2 is easily deformed due to the extrusion of the bobbin 2 and the housing 1. If the deformation of the insulating sheet 3 is controlled within a suitable range, the bobbin 2 can be ensured to be in a suitable pressure state (when the external pressure on the bobbin 2 is too large, its diaphragm and pole pieces are easily damaged, resulting in the risk of internal short circuit of the bobbin 2), and remain in a fixed state. Moreover, if the bobbin 2 retains sufficient deformation compression margin, it can also avoid excessive pressure on the bobbin 2 during the caulking sealing of the battery.

[0026] In some embodiments, before Step S2, it further includes: Initialize the length of the bobbin accommodating portion 11 in the first direction according to the length of the bobbin 2 in the first direction, the thickness of the bottom wall of the housing 1, and the thickness of the side wall of the housing 1.

[0027] Specifically, the initial value of the length of the bobbin accommodating portion 11 in the first direction is equal to the sum of the length of the bobbin 2 of the battery in the first direction, the thickness of the bottom wall of the housing 1, and the thickness of the side wall of the housing 1.

[0028] Please refer to Figure 2 and Figure 3 In some embodiments, determining whether the deformation of the insulating sheet 3 of the bobbin 2 is within the first preset range further includes: If the judgment result is no, adjust the processing position of the hob on the housing 1 in the first direction to adjust the length of the bobbin accommodating portion 11 in the first direction, and adjust the feed amount of the hob and re-execute Step S2.

[0029] Specifically, when the deformation of the insulating sheet 3 is less than the lower limit of the first preset range, reduce the length of the bobbin accommodating portion 11 in the first direction and increase the feed amount of the hob.

[0030] Specifically, when the deformation of the insulating sheet 3 is greater than the upper limit of the first preset range, increase the length of the bobbin accommodating portion 11 in the first direction and reduce the feed amount of the hob.

[0031] Optionally, the first preset range is 0.5 - 1.0 mm.

[0032] Optionally, the feed amount of the hob is between 1.5 - 3 mm.

[0033] Optionally, the side wall thickness at the location of the rolling groove 121 on the housing 1 is greater than or equal to 70% of the side wall thickness at this position on the housing 1 before the hob machining, to avoid the risk of liquid leakage due to excessive stretching of the housing 1.

[0034] In some embodiments, the deformation amount of the insulating sheet 3 of the core 2 is obtained by analyzing the cross-section of the battery intercepted along the first direction.

[0035] Step S3: Determine whether the difference between the thickness of the sealing ring 5 and the length of the housing opening 13 in the first direction is within a second preset range. If so, determine the length of the housing opening 13 in the first direction.

[0036] In some embodiments, before step S3, it further includes: Initialize the length of the housing opening 13 in the first direction. The initial value of the length of the housing opening 13 in the first direction is equal to the length of the cover plate 4 of the battery in the first direction.

[0037] Please refer to Figure 2 and Figure 4 , in some embodiments, determining whether the difference between the length of the sealing ring 5 of the cover plate 4 of the battery and the length of the housing opening 13 in the first direction is within a second preset range further includes: If the judgment result is negative, adjust the width of the cutting face of the hob to adjust the length of the housing opening 13 in the first direction, and re-execute step S3.

[0038] Optionally, the second preset range is 0.5 - 1.5 mm, to ensure that the sealing ring 5 appropriately extends beyond the housing opening 13, so as to ensure that after sealing the housing opening 13 with the sealing ring 5, the sealing ring 5 leaks outside the edge of the housing 1, to ensure the sealing airtightness.

[0039] Compared with the prior art, in this application, by using a hob to process the battery, it is determined whether the deformation amount of the insulating sheet 3 of the core 2 is within a first preset range. If so, the length of the core accommodating portion 11 in the first direction and the feed amount of the hob are determined; it is judged whether the difference between the thickness of the sealing ring 5 and the length of the shell opening portion 13 in the first direction is within a second preset range. If so, the length of the shell opening portion 13 in the first direction is determined. By first determining the length of the core accommodating portion 11 in the first direction and the feed amount of the hob, and then determining the length of the shell opening portion 13 in the first direction, that is, by first orderly determining some change factors of the cylindrical battery and then adjusting other change factors, it is possible to avoid the situation where a single change in the process of parameter adjustment in the grooving 121 process affects the whole situation, simplifies the adjustment process of the grooving 121 of the cylindrical battery, improves the adjustment efficiency of the grooving 121 process, and since when adjusting some of the parameters, there is no need to pay attention to other parameters, it is possible to concentrate on the adjustment, thereby effectively coping with the problem of the small process window of the grooving adjustment process. In addition, the grooving adjustment method of the cylindrical battery of this application is applicable to all cylindrical structure designs with mechanical sealing by grooving, and is not limited to the shells made of materials such as steel shells and aluminum shells, and has a wide application range.

[0040] It can be understood that the grooving adjustment method of the cylindrical battery of this application can be carried out in reality or simulated on electronic devices such as computers.

[0041] Please refer to Figure 5 , this application also discloses an electronic device, including: A processor 30; A memory 40, in which executable instructions of the processor 30 are stored; Wherein, the processor 30 is configured to execute the above-mentioned grooving adjustment method of the cylindrical battery.

[0042] This application also discloses a computer-readable storage medium, on which a program is stored, and when the program is executed by the processor 30, the above-mentioned grooving adjustment method of the cylindrical battery is implemented.

[0043] The above-disclosed are only the preferred embodiments of this application, and of course, the scope of rights of this application cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of this application still fall within the scope covered by this application.
