Description

Technical Field

[0002] During the production process, the battery cells need to be assembled using battery cell processing equipment. After the end cap and the shell are welded, the battery cell processing equipment is used to bend the end cap relative to the shell and cover the opening of the shell. Specifically, in the initial state of the cylindrical battery cell, the end cap is arranged parallel to the opening and does not cover the opening of the shell, that is, the axis of the shell coincides with the axis of the end cap.

[0003] In the prior art, a bending assembly is used to continuously bend the end cap 180 degrees relative to the shell to cover the opening. However, during the continuous bending process, the end cap accumulates excessive stress, which makes it easy for the end cap to break relative to the shell. In addition, since the continuous bending stroke of the end cap is large, the springback rate of the end cap bending is large, resulting in poor closing accuracy of the battery cell during assembly. In summary, the processing yield rate of cylindrical battery cells is low. Utility Model Content

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] In the prior art, a bending assembly is used to continuously bend the end cap 180 degrees relative to the shell to cover the opening. However, during the continuous bending process, the end cap accumulates excessive stress, which makes it easy for the end cap to break relative to the shell. In addition, since the continuous bending stroke of the end cap is large, the springback rate of the end cap bending is large, resulting in poor closing accuracy of the battery cell during assembly. In summary, the processing yield rate of cylindrical battery cells is low.

[0045] In view of this, the first embodiment of the present invention provides a battery cell processing device 10, which can ensure the yield rate of the battery cell. The battery cell processing device 10 is used to process the cylindrical battery cell 20. Figures 1 to 3 The cylindrical battery cell 20 includes a shell 201 and an end cap 202. The shell 201 is provided with an opening 2011 along its axis 2012. The battery cell processing device 10 is used to make the end cap 202 cover the opening 2011. Figures 4 to 8 The battery cell processing device 10 according to the embodiment of the present application is introduced. Specifically, the battery cell processing device 10 includes a fixing portion 100, a first bending assembly 200 and a second bending assembly 300.

[0046] Reference Figure 4 and Figure 5 The fixing part 100 is used to fix the housing 201, so that the end cover 202 can be stably bent relative to the housing 201. The specific configuration of the fixing part 100 can refer to the related known technology.

[0047] Reference Figure 4 and Figure 5, the first bending assembly 200 is used to make the end cover 202 perform the initial bending. Specifically, when the end cover 202 needs to be bent, the first bending assembly 200 can be connected to the end cover 202. The first bending assembly 200 can drive the end cover 202 to bend at a first angle relative to the shell 201 around the first axis a. It should be noted that the first axis a is perpendicular to the axis 2012 of the shell 201. The specific size of the first angle depends on the actual situation. Some embodiments of the present application are described by taking the first angle of 90 degrees as an example. It can be understood that before the end cover 202 is bent by the first bending assembly 200, the axis 2012 of the end cover 202 is parallel to the axis 2012 of the shell 201 (the end cover 202 does not cover the opening 2011); after the end cover 202 is bent by the first bending assembly 200, the axis 2012 of the end cover 202 is perpendicular to the axis 2012 of the shell 201 (the end cover 202 does not cover the opening 2011).

[0048] Reference Figure 4 and Figure 6 , the second bending assembly 300 is used to bend the end cover 202 for a second time. Specifically, when the end cover 202 that has completed the initial bending needs to be bent for a second time, the second bending assembly can be connected to the end cover 202. The second bending assembly 300 is used to drive the end cover 202 to bend a second angle around the second axis b relative to the shell 201. It should be noted that the second axis b is parallel to the first axis a, and thus the second axis b is also perpendicular to the axis 2012 of the shell 201. The size of the second angle may depend on the actual situation. Some embodiments of the present application are described by taking the second angle of 90 degrees as an example. Similarly, after the end cover 202 is bent by the first bending assembly 200 and before it is bent by the second bending assembly 300, the axis 2012 of the end cover 202 is perpendicular to the axis 2012 of the shell 201 (the end cover 202 does not cover the opening 2011); refer to Figure 2 When the end cap 202 is bent by the second bending assembly 300, the axis 2012 of the end cap 202 is parallel to the axis 2012 of the housing 201 (when viewed along the axis 2012 of the housing 201, the housing 201 covers the opening 2011). Figure 4 It should be noted that the first bending assembly 200 and the second bending assembly 300 can jointly drive the end cover 202 to bend relative to the shell 201, so that the end cover 202 covers the opening 2011 to complete the assembly of the battery cell.

[0049] In the technical solution of the utility model, the battery core processing equipment 10 includes a fixing part 100, a first bending assembly 200 and a second bending assembly 300. The fixing part 100 is used to fix the shell 201. Compared with the solution in the prior art that the bending assembly makes the end cover continuously bend 180 degrees relative to the shell to cover the opening, in this solution, the first bending assembly 200 can drive the end cover 202 to bend at a first angle around the first axis a relative to the shell 201, and the second bending assembly 300 can drive the end cover 202 to bend at a second angle around the second axis b relative to the shell 201, that is, the first bending assembly 200 and the second bending assembly 300 jointly drive the end cover 202 to make the end cover 202 cover the opening 2011, so the end cover 202 will be bent twice, that is, the stress on the bending part connected to the end cover 202 will not be excessively accumulated, and the possibility of the end cover 202 breaking is smaller than that of the shell 201. In addition, since the end cap 202 is bent twice, the bending stroke of the end cap 202 is smaller, that is, the springback rate of the bending of the end cap 202 is smaller, which facilitates the adjustment of the bending angle of the end cap 202 and ensures the closing accuracy of the battery cell. That is, the cylindrical battery cell 20 of this solution has a high yield rate.

[0050] In some embodiments, reference Figure 1 The cylindrical battery cell 20 includes a connecting portion 203, one end of the connecting portion 203 is connected to the end cover 202, and the other end is connected to the housing 201. It can be understood that the cover plate can be welded to the housing 201 through the connecting portion 203. The connecting portion 203 has a first bending portion 2031 close to the housing 201 and a second bending portion 2032 away from the housing 201. The specific positions of the first bending portion 2031 and the second bending portion 2032 can be determined according to actual conditions.

[0051] The first bending assembly 200 drives the first bending portion 2031 to bend around the first axis a, so that the end cover 202 is bent at a first angle relative to the housing 201, that is, the end cover 202 can complete the initial bending. The second bending assembly 300 drives the second bending portion 2032 to bend around the second axis b, so that the end cover 202 is bent at a second angle relative to the housing 201, that is, the end cover 202 can complete the secondary bending.

[0052] In this solution, the second axis b is spaced from the first axis a, that is, the bending position of the first bending portion 2031 is different from the bending position of the second bending portion 2032. Therefore, the stress accumulation at a single bending position of the connecting portion 203 can be reduced, and the possibility of the connecting portion 203 breaking when the end cover 202 is bent relative to the shell 201 is further reduced, thereby improving the yield rate of the cylindrical battery cell 20.

[0053] Reference Figure 4 and Figure 5, the specific setting of the first bending assembly 200 is introduced below. In some embodiments, the first bending assembly 200 includes a first positioning portion 210 and a first guiding portion 220. The first positioning portion 210 is used to abut the first bending portion 2031 to accurately control the bending position of the first bending portion 2031. It can be understood that in order to prevent the first positioning portion 210 from affecting the normal bending of the first bending portion 2031, the cross-sectional area of ​​the end of the first positioning portion 210 close to the first bending portion 2031 can be made smaller than the cross-sectional area of ​​the end of the first positioning portion 210 away from the first bending portion 2031. The first guiding portion 220 is used to drive the end cover 202 to bend at a first angle relative to the housing 201. The specific movement trajectory of the first guiding portion 220 can be determined according to the bending angle of the end cover 202. By setting the first positioning portion 210 and the first guiding portion 220, this solution facilitates accurate control and adjustment of the bending position and bending accuracy of the connecting portion 203, thereby ensuring the closing quality of the cylindrical battery cell 20.

[0054] Reference Figure 4 and Figure 5 In some embodiments, the battery core processing equipment 10 further includes a first driving assembly 400, and the first driving assembly 400 is used to increase the driving force for the first bending assembly 200. Specifically, the first driving assembly 400 includes a first driving part 410 and a second driving part 420. In order to facilitate the description and understanding of the specific driving process of the first driving assembly 400, a first direction X is defined. The first driving part 410 drives the first positioning part 210 to move along the first direction X to abut against the first bending part 2031. The second driving part 420 drives the first guiding part 220 to move along the first direction X to bend the end cover 202 relative to the shell 201. Among them, the first direction X intersects with the axis 2012 direction of the shell 201. It should be noted that in some embodiments, the first direction X can be arranged obliquely with the axis 2012 direction of the shell 201. In other embodiments, the first direction X can be arranged perpendicularly with the axis 2012 direction of the shell 201. Some embodiments of the present application are described by taking the first direction X and the axis 2012 direction of the shell 201 as an example. In this solution, the movement directions of the first positioning portion 210 and the first guiding portion 220 are parallel, which can enhance the overall stability of the first driving assembly 400. Moreover, since the first direction X is inclined with the axis 2012 of the shell 201, the driving stroke of the first driving assembly 400 can be shortened, thereby improving the bending efficiency.

[0055] Reference Figure 4 and Figure 6, the specific configuration of the second bending assembly 300 is introduced below. In some embodiments, the second bending assembly 300 includes a second positioning portion 310, a third positioning portion 320 and a second guiding portion 330. The second positioning portion 310 is used to abut against the first bending portion 2031, and the third positioning portion 320 is used to abut against the second bending portion 2032. The second guiding portion 330 is used to drive the end cover 202 to bend at a second angle relative to the shell 201. The second bending assembly 300 of this solution can make the connecting portion 203 fold in a Z shape, so that the axis of the end cover 202 is parallel to the axis 2012 of the shell 201, thereby ensuring the accuracy of closing the cover.

[0056] Reference Figure 4 and Figure 6 In some embodiments, the battery core processing device 10 further includes a second driving assembly 500, which is used to increase the driving force for the second bending assembly 300. The second driving assembly 500 includes a third driving unit 510, a fourth driving unit 520, and a fifth driving unit 530. In order to facilitate the description and understanding of the specific driving process of the second driving assembly 500, a second direction Y and a third direction Z are defined. The second direction Y intersects with the axis 2012 of the housing 201, and the third direction Z is perpendicular to the axis 2012 of the housing 201.

[0057] The third driving part 510 drives the second positioning part 310 to move along the second direction Y to abut against the first bending part 2031. The fourth driving part 520 drives the third positioning part 320 to move along the third direction Z to abut against the second bending part 2032. The fifth driving part 530 drives the second guiding part 330 to move along the second direction Y to bend the end cover 202 relative to the housing 201. The above driving process can effectively shorten the movement stroke of the second guiding part 330 and improve the bending efficiency of the second bending assembly 300.

[0058] Reference Figure 4 , Figure 7 and Figure 8 In some embodiments, the battery cell processing equipment 10 further includes a cover assembly 600, which is used to drive the end cover 202 to cover the opening 2011 so as to realize the assembly of the cylindrical battery cell 20. The specific configuration of the cover assembly 600 is described below. The cover assembly 600 includes an adjustment portion 610, which is used to drive the end cover 202 to move along a fourth direction V so that the axis 2012 of the end cover 202 coincides with the axis 2012 of the shell 201, thereby ensuring the cover accuracy of the battery cell. It should be noted that the fourth direction V intersects with the axis 2012 of the shell 201, and some embodiments of the present application are described by taking the fourth direction V and the axis 2012 of the shell 201 as an example of an inclined arrangement.

[0059] Reference Figure 7 and Figure 8In some embodiments, the cover assembly 600 includes a clamping portion 620 and a pushing portion 630. The clamping portion 620 surrounds and fixes the end cap 202, and can ensure the stability of the connection between the end cap 202 and the cover assembly 600. Along the axis 2012 parallel to the shell 201, the pushing portion 630 drives the end cap 202 to approach the shell 201, that is, the end cap 202 can cover the opening 2011 of the shell 201, and the cylindrical battery cell 20 is assembled.

[0060] Reference Figure 8 In some embodiments, the lid closing assembly 600 further includes a connecting rod 640. One end of the connecting rod 640 is connected to the clamping portion 620, and the other end is connected to the propulsion portion 630. By adding the connecting rod 640, this solution can not only ensure the propulsion accuracy of the propulsion portion 630, but also reduce the movement stroke of the clamping portion 620, thereby improving the lid closing efficiency.

[0061] The second embodiment of the present invention provides a production line, which includes the battery cell processing equipment 10 as described in the above embodiment. The production line of this solution can improve the accuracy of the battery cell cover and ensure the yield rate of the cylindrical battery cell 20.
