[0058] See also Figure 2 as well as Figure 3 , Figure 2 for Figure 1 The schematic diagram of the structure of the battery 10 is shown. Figure 3 for Figure 2 The partial cross-sectional schematic diagram of the battery 10 shown in FIG. 1 includes a housing 11, a first battery cell 12, and a second battery cell 13. The housing 11 is provided with an end cap 16. The first battery cell 12 and the second battery cell 13 are arranged in the housing 11, so as to protect the first battery cell 12 and the second battery cell 13 with the help of the housing 11. The first battery cell 12 and the second battery cell 13 are stacked along a first direction F1 parallel to the end cap 16, so that the space inside the housing 11 can be effectively utilized to increase the energy density of the battery 10.

[0059] The first battery cell 12 is provided with a first pole tab 121, and the second battery cell 13 is provided with a second pole tab 131. One end of the first pole tab 121 away from the first battery cell 12 and one end of the second pole tab 131 away from the second battery cell 13 are connected to the first position 161 of the end cover 16. Along the first direction F1, the first position 161 is located between the first battery cell 12 and the second battery cell 13. Exemplarily, one end of the first pole tab 121 away from the first battery cell 12 and one end of the second pole tab 131 away from the second battery cell 13 are welded to the first position 161 of the end cover 16.

[0060] In this way, the length of the first pole ear 121 and the length of the second pole ear 131 can be made more uniform, and the first pole ear 121 and the second pole ear 131 are subjected to the same force during the assembly process. In this way, the problems of breakage and damage of multiple pole ears due to different forces during the processing can be avoided, thereby reducing the quality fluctuation during the production process, improving the yield rate of the battery 10, improving the processing quality of the battery 10, and facilitating the processing of the battery 10.

[0080] See also Figure 4 , Figure 4The present application provides a schematic diagram of the structure of a battery processing device 200, and the present application also provides a battery processing device 200, including a fixing assembly 30 and an end cap driving assembly 40. The fixing assembly 30 is used to fix the battery 10 to ensure that the position of the battery 10 does not shift during the processing, thereby improving the processing accuracy and ensuring good contact between the end cap 16 and the battery cell. The battery 10 includes a shell 11, a battery cell and an end cap 16. The shell 11 is provided with an opening 111, and the end cap 16 is located on the side facing the opening 111. The battery cell is arranged in the shell 11, and the battery cell is provided with a pole ear, and the end of the pole ear away from the battery cell is connected to the end cap 16.

[0081] The end cap driving assembly 40 is used to drive the end cap 16 to move toward the opening 111, and fold the tab during the movement. In this way, during the movement of the end cap 16, the folding design of the tab can effectively reduce the space occupied, avoid damage to the tab during the assembly process, and ensure the reliability of the connection.

[0082] It should be noted that the number of the end cap drive assembly 40 can be one or two, and the present application does not limit this. For example, the present application takes the number of the end cap drive assembly 40 as two as an example for explanation. In this way, the end caps 16 on both sides of the battery 10 can be installed at the same time, and the installation efficiency is higher.

[0083] In some embodiments, see Figure 4 as well as Figure 5 , Figure 5 for Figure 4 An exploded schematic diagram of an end cap drive assembly 40 is shown, and the end cap drive assembly 40 includes a clamping assembly 41 and a clamping drive device 42. The clamping assembly 41 is used to clamp the end cap 16 to ensure that the end cap 16 will not loosen or fall off during the movement, thereby improving the stability and reliability of the assembly. The clamping drive device 42 is connected to the clamping assembly 41, and the clamping drive device 42 is used to drive the clamping assembly 41 to move toward the opening 111, so as to drive the end cap 16 to move toward the opening 111. In this way, the clamping and moving process can be automated, reducing the need for manual operation and improving production efficiency.

[0084] In some embodiments, continue to refer to Figure 5 The clamping assembly 41 includes a plurality of clamping jaws 411 and a limiting assembly 412. The plurality of clamping jaws 411 are used to limit the end cover 16 from the side of the end cover 16 facing the opening 111. The limiting assembly 412 limits the end cover 16 from the side of the end cover 16 facing away from the opening 111.

[0085] In this way, the multiple clamping jaws 411 can evenly distribute the clamping force to ensure that the end cover 16 remains stable during movement. The multiple clamping jaws 411 and the limiting assembly 412 can limit the position of the end cover 16 in multiple directions to reduce the displacement or deformation of the end cover 16.

[0086] It should be noted that the present application does not limit the number of the clamping jaws 411, which is set according to actual conditions. For example, the number of the clamping jaws 411 can be two, three, four, etc.

[0087] In some embodiments, the limiting assembly 412 includes a first limiting assembly 4121, a second limiting assembly 4122, and a limiting driving device 4123. The first limiting assembly 4121 includes a first limiting portion 4127 and a second limiting portion 4128, wherein the first limiting portion 4127 limits the end cover 16 by the side of the end cover 16 facing away from the opening 111, and the second limiting portion 4128 limits the end cover 16 by two adjacent edges of the end cover 16. The second limiting assembly 4122 includes a third limiting portion 4129, wherein the third limiting portion limits the end cover 16 by two other adjacent edges of the end cover 16. The limiting driving device 4123 is used to drive the second limiting assembly 4122 to move in a direction of approaching or moving away from each other in a plane parallel to the opening 111.

[0088] In this way, the first limiting assembly 4121 and the second limiting assembly 4122 can limit the edge of the end cover 16. The first limiting assembly 4121 and the second limiting assembly 4122 can be moved in a plane parallel to the opening 111 by the limiting driving device 4123 to adjust the clamping position. In this way, end covers 16 of different sizes can be clamped.

[0089] In some embodiments, the clamping assembly 41 further includes a pole clamping member 4124 and a pushing device 4125. The pole clamping member 4124 is located between the first limiting assembly 4121 and the second limiting assembly 4122, and the pole clamping member 4124 is used to clamp the pole 17 of the end cover 16. The pushing device 4125 is used to push the pole clamping member 4124 to drive the pole clamping member 4124 to move toward the opening 111, so as to drive the end cover 16 to move toward the opening 111.

[0090] In this way, the pole clamp 4124 is used to clamp the pole 17 of the end cover 16, ensuring the stability and accuracy of the pole 17 during the assembly process, and avoiding damage or deformation of the pole 17 due to improper clamping. In addition, during the installation of the end cover 16, the limit assembly 412 can be loosened, the limit on the peripheral side of the end cover 16 can be cancelled, and the end cover 16 can be clamped by the pole clamp 4124, which facilitates the installation of the end cover 16.

[0091] In some embodiments, a movable connection member 4126 is provided between the pushing device 4125 and the pole clamping member 4124 , and the movable connection member 4126 can be bent and deformed so as to enable the pole clamping member 4124 to move in a plane parallel to the opening 111 .

[0092] In this way, the bending deformation of the movable connecting member 4126 enables the pole clamping member 4124 to flexibly move in a plane parallel to the opening 111, adapting to different assembly requirements and environmental changes. The flexibility of the movable connecting member 4126 enables the pole clamping member 4124 to be more easily aligned with the opening 111 during the assembly process, simplifying the operation process and improving the assembly efficiency.

[0093] In some embodiments, the movable connecting member 4126 is a ball plunger. The ball plunger has a simple structure and can move freely in multiple directions, and is suitable for a variety of application scenarios.

[0094] See also Figure 6 , Figure 6 A partial cross-sectional schematic diagram of a battery cell installation provided in an embodiment of the present application, the battery cell includes a first battery cell 12 and a second battery cell 13. The first battery cell 12 and the second battery cell 13 are stacked along a first direction F1 parallel to the opening 111. The first battery cell 12 is provided with a first pole ear 121, and the second battery cell 13 is provided with a second pole ear 131. An end of the first pole ear 121 away from the first battery cell 12 and an end of the second pole ear 131 away from the second battery cell 13 are connected to a first position 161 of the end cover 16. The first battery cell 12 and the second battery cell 13 are stacked, which can effectively utilize the space inside the shell 11 and increase the energy density of the battery 10.

[0095] The first pole tab 121 and the second pole tab 131 are connected to the first position 161 of the end cap 16, so that the length of the first pole tab 121 and the length of the second pole tab 131 can be relatively uniform, and the first pole tab 121 and the second pole tab 131 are subjected to the same force during the assembly process. In this way, the problems of breakage and damage of multiple pole tabs due to different forces during the processing can be avoided, thereby reducing the quality fluctuation during the production process, improving the yield rate of the battery 10, improving the processing quality of the battery 10, and facilitating the processing of the battery 10.

[0096] See also Figure 6 Combined with Figure 7 , Figure 7 for Figure 4 The partial structural schematic diagram of the battery processing equipment 200 is shown. Figure 6The bending assembly 43 is in the first state. The battery processing equipment 200 further includes a bending assembly 43, and the bending assembly 43 includes a bending portion 431 and a driving portion 432. The bending assembly 43 has a first state. When the bending assembly 43 is in the first state, the bending portion 431 is located between the first pole lug 121 and the second pole lug 131. The driving portion 432 is used to drive the bending portion 431 to move along the first direction F1, so that the first pole lug 121 is bent in a direction away from the second pole lug 131.

[0097] By providing the bending assembly 43, the first pole ear 121 can be bent and the shape of the first pole ear 121 can be adjusted, so that the first pole ear 121 can be prevented from being irregularly bent during the assembly of the end cap 16, thereby affecting the output of electricity. This can reduce quality fluctuations during the production process, improve the assembly yield of the battery 10, and improve the processing quality of the battery 10.

[0098] It should be noted that the present application does not limit the number of bending components 43, which can be set according to actual needs.

[0099] For example, the bending assembly 43 may be one, two, three, or four. The present application is described with four bending assemblies 43. In this way, the tabs of the positive and negative electrodes of the battery 10 can be bent at the same time, and the contact area between the bending assembly 43 and the first tab 121 and the second tab 131 can be ensured, thereby improving the success rate of the tab bending.

[0100] In some other embodiments, when the bending assembly 43 is in the first state, the bending portion 431 is located between the first pole tab 121 and the second pole tab 131. The driving portion 432 is used to drive the bending portion 431 to move along the first direction F1, so that the second pole tab 131 is bent in a direction away from the first pole tab 121. By providing the bending assembly 43, the second pole tab 131 can be bent and the shape of the second pole tab 131 can be adjusted, so that the second pole tab 131 can be prevented from being folded multiple times during the assembly process of the end cover 16, thereby affecting the output of electricity.

[0101] It should be noted that the present application does not limit the number of the bending portions 431, which can be set according to actual needs. For example, the number of the bending portions 431 is two.

[0102] In some embodiments, the bending portion 431 includes a first bending unit 4311 and a second bending unit 4312. When the bending assembly 43 is in the first state, the first bending unit 4311 and the second bending unit 4312 are located between the first pole tab 121 and the second pole tab 131. The driving unit 432 is used to drive the first bending unit 4311 and the second bending unit 4312 to move along the first direction F1, so that the first pole tab 121 and the second pole tab 131 are bent in a direction away from each other.

[0103] In this way, the first bending unit 4311 and the second bending unit 4312 can bend the first pole tab 121 and the second pole tab 131 at the same time, thereby improving the bending efficiency and further improving the processing efficiency.

[0104] In some embodiments, continue to refer to Figure 7 The battery processing equipment 200 further includes a first driving device 50, and the bending assembly 43 is connected to the first driving device 50. The first driving device 50 is used to drive the bending assembly 43 to move along the second direction F2 to drive the bending assembly 43 to move to the second state. When the bending assembly 43 is in the second state, the bending assembly 43 is located outside the space between the end cover 16 and the opening 111.

[0105] In this way, by providing the first driving device 50 , the bending assembly 43 can be driven to move to the second state. The bending assembly 43 in the second state is a state where the bending assembly 43 does not need to bend the first pole tab 121 and the second pole tab 131 .

[0106] In some embodiments, the first driving device 50 includes a first driving unit 51 and a second driving unit 52. The bending assembly 43 is connected to the first driving unit 51, and the first driving unit 51 is used to drive the bending assembly 43 to move along the second direction F2. The first driving unit 51 is connected to the second driving unit 52, and the second driving unit 52 is used to drive the bending assembly 43 to move along the second direction F2.

[0107] In this way, through the coordinated work of the first drive unit 51 and the second drive unit 52, the bending component 43 can realize movement in the second direction F2. This can reduce the size of the first drive device 50 in the second direction F2 while ensuring a larger travel range of the bending component 43, thereby improving the compactness of the bending component 43.

[0108] In some embodiments, continue to refer to Figure 4 as well as Figure 7 The battery processing equipment 200 further includes a second driving device 60, and the first driving device 50 is connected to the second driving device 60. The second driving device 60 is used to drive the bending assembly 43 to move along the third direction F3. The third direction F3 is perpendicular to the opening 111.

[0109] By providing the second driving device 60 , the bending assembly 43 can be flexibly moved in the third direction F3 to adapt to different operation requirements and environmental conditions.

[0110] It is understandable that the battery has a shell, and the tabs are located inside the shell. In this way, the second drive unit 52 can drive the bending component 43 to approach the battery shell, and the second drive device 60 drives the bending component 43 to move along the third direction F3 toward the tab, so that the bending component 43 can be close to the edge of the tab. At this time, the first drive unit 51 drives the bending component 43 to continue to move, so that the bending component 43 is inserted into the position between the tabs, so that the precise positioning of the bending component 43 can be completed.

[0111] In some embodiments, the first driving device 50 and the second driving device 60 are driving cylinders. The driving cylinders have a simple structure and are easy to process.

[0112] In some other embodiments, the first driving device 50 and the second driving device 60 may also be motors or the like.

[0113] In some embodiments, see Figure 8 , Figure 8 for Figure 4 The structural schematic diagram of the fixing assembly 30 shown in the figure includes a battery placement rack 31 and an end cap placement rack 32. The battery placement rack 31 is used to place the battery 10. The end cap placement rack 32 is arranged on the first side and is located between the battery placement rack 31 and the end cap drive assembly 40. The end cap placement rack 32 is used to place the end cap 16 and drive the end cap 16 to move in the first direction F1. Among them, the first side refers to the lower side in the first direction F1.

[0114] It is understandable that after the battery cell is placed on the battery placement rack 31, since the end cap 16 and the battery cell are connected only by the pole piece, under the action of gravity, the end cap 16 and the battery cell will be misaligned. In this way, the end cap placement rack 32 can carry the end cap 16 and move the end cap 16 in the first direction F1 so that the end cap 16 and the battery cell are at the same height, which is convenient for the end cap drive assembly 40 to limit the end cap 16 and perform subsequent operations.

[0115] In some other embodiments, the fixing assembly 30 further includes a battery fixing member 33 , through which the battery cell can be limited in multiple directions to prevent the battery cell from being misplaced, thereby facilitating the installation of the end cover 16 .

[0116] It should be noted that when processing the battery 10, after the first battery cell 12 and the second battery cell 13 are placed in the battery placement rack 31, the battery 10 fixing parts complete the fixing of the first battery cell 12 and the second battery cell 13, and the end cover 16 is placed on the end cover placement rack 32. The end cover placement rack 32 moves in the first direction F1 to complete the positioning of the end cover 16 in the first direction F1. At this time, the end cover driving assembly 40 clamps the cover plate to complete the fixing of the cover plate. After completing the above actions, the end cover driving assembly 40 drives the cover plate to move away from the first battery cell 12 and the second battery cell 13 to pull the first pole ear 121 and the second pole ear 131 to a flat state, and there is enough space between the first pole ear 121 and the second pole ear 131 to facilitate the bending assembly 43 to move to the first state, that is, to be inserted between the first pole ear 121 and the second pole ear 131. When the bending assembly 43 moves to between the first pole lug 121 and the second pole lug 131, the end cap driving assembly 40 drives the cover plate to move toward the first battery cell 12 and the second battery cell 13, leaving a certain length margin for the first pole lug 121 and the second pole lug 131, so as to facilitate bending the first pole lug 121 and the second pole lug 131. At this time, the first bending unit 4311 is driven by the driving part 432 of the bending assembly 43 to move upward to bend the first pole lug 121, and the second bending unit 4312 is driven to move downward to bend the second pole lug 131. After the first pole lug 121 and the second pole lug 131 are bent, the bending assembly 43 moves to the second state, that is, the bending assembly 43 withdraws from between the first pole lug 121 and the second pole lug 131. At this time, the end cover driving assembly 40 drives the end cover 16 to move toward the first battery cell 12 and the second battery cell 13, the clamping assembly 41 releases the edge limit of the end cover 16, clamps the pole 17 through the pole clamping member 4124, and then drives the end cover 16 to be installed toward the first battery cell 12 and the second battery cell 13, completing the assembly of the entire battery 10.

[0117] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0118] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
