[0052] In the production process of the battery monomer 30, it is usually necessary to carry out formation process, and in the formation process, gas will be generated inside the battery monomer 30. These gases need to be discharged to the outside of the battery monomer 30 in time. If the gas inside the battery monomer 30 is not discharged in time, the transmission of lithium ions and other metal ions will be affected during the formation process of the battery monomer 30, thereby causing the risk of black spots or lithium precipitation in some areas of the pole piece inside the battery monomer 30, which seriously affects the reliability of the produced battery monomer 30.

[0053] Therefore, in a first aspect, as shown in Figure 1 and Figure 2 The clamping and vibrating device 1 provided by the embodiments of the application is used for clamping the battery monomer 30 and providing a vibrating force for the battery monomer 30. The clamping and vibrating device 1 comprises a clamping assembly 20 and a vibrating assembly 10. The clamping assembly 20 is used for clamping the battery monomer 30. The vibrating assembly 10 is connected with the clamping assembly 20 and is used for providing an exciting force for the clamping assembly 20.

[0054] The clamping assembly 20 is used to clamp the battery cell 30, and can be provided in any suitable structure, and the clamping assembly 20 can clamp one or more battery cells 30 to provide a stable clamping force for the battery cell 30.

[0055] The vibration assembly 10 can include a vibrator or a vibration table, and the like, and can include an electromagnetic vibrator or a rotor vibrator, and the like.

[0056] The vibration assembly 10 is connected to the clamping assembly 20 and can provide an excitation force to the clamping assembly 20, so that when the clamping assembly 20 clamps the battery cell 30, the vibration assembly 10 can act as a vibration source, and the excitation force generated by the vibration assembly 10 is transmitted to the clamping assembly 20 and then to the battery cell 30 through the clamping assembly 20, so that the battery cell 30 vibrates.

[0057] It can be understood that the excitation force and frequency of the vibration assembly 10 can be set as needed to make the battery cell 30 have a suitable vibration frequency and vibration amplitude.

[0058] Specifically, during the production of the battery cell 30, after the battery cell 30 is injected with electrolyte, an excitation force can be provided to the battery cell 30 to make the battery cell 30 vibrate, and the electrolyte inside the battery cell 30 appears a physical phenomenon similar to boiling at a certain vibration frequency, thereby accelerating the electrolyte climbing rate, greatly improving the wettability of the electrolyte to the electrode assembly, greatly shortening the wettability process time in the production process of the battery cell 30, speeding up the production rhythm of the battery cell 30, and being beneficial to improving the production efficiency of the battery cell 30.

[0059] In addition, during the formation process of the battery cell 30, the electrode assembly inside the battery cell 30 will generate a lot of gas, which is usually first stored in the electrolyte between the electrode plates inside the electrode assembly. By clamping the battery cell 30 and providing an excitation force to the battery cell 30 to make the battery cell 30 vibrate, it is beneficial to accelerate the discharge of the gas in the electrolyte to the outside of the electrolyte, and then to the outside of the battery cell 30, thereby reducing the content of the gas in the electrolyte, and in the formation process, it is beneficial to improve the smoothness of the transmission path of lithium ions and other metal ions, and reduce the risk of black spots or lithium precipitation on the electrode plates of the battery cell 30.

[0060] Further, for some battery monomers 30, it is often necessary to inject electrolyte twice, and the compositions of the electrolyte injected twice are different. After the second injection of electrolyte to the battery monomer 30, the clamping and vibrating device 1 provides the battery monomer 30 with a vibration exciting force while clamping the battery monomer 30, so that the electrolyte inside the battery monomer 30 is mixed more quickly and uniformly, which is conducive to reducing the risk of stratification of the electrolyte inside the battery monomer 30, improving the interface problem inside the battery monomer 30, and improving the stability of the electrochemical performance of the battery monomer 30.

[0061] Optionally, the clamping and vibrating device 1 can include one clamping assembly 20 and one vibrating assembly 10, or the clamping and vibrating device 1 includes multiple clamping assemblies 20 and one vibrating assembly 10, and the vibrating assembly 10 provides vibration force for the multiple clamping assemblies 20. Of course, the clamping and vibrating device 1 can also include multiple clamping assemblies 20 and multiple vibrating assemblies 10, so that the clamping and vibrating device 1 can perform at least two processes of formation, electrolyte injection, and second injection of electrolyte on the battery monomer 30 at the same time.

[0062] The clamping and vibrating device 1 provided by the embodiment of the present application includes the clamping assembly 20 and the vibrating assembly 10, so that the battery monomer 30 is provided with a vibration exciting force while being clamped, so that the battery monomer 30 vibrates. In the formation process of the battery monomer 30, it is conducive to accelerating the discharge of the gas inside the battery monomer 30, improving the smoothness of the transmission of metal ions such as lithium ions, and reducing the risk of black spots or lithium precipitation of the pole piece of the battery monomer 30. In the process of injecting electrolyte, it is conducive to improving the wetting rate of the electrolyte to the pole piece and improving the production efficiency of the battery monomer 30. After the second injection of electrolyte, the battery monomer 30 vibrates, which is conducive to improving the mixing rate and uniformity of the electrolyte inside the battery monomer 30, improving the production efficiency of the battery monomer 30, and improving the electrochemical stability of the battery monomer 30, thereby improving the reliability of the battery monomer 30. Therefore, the clamping and vibrating device 1 provided by the embodiment of the present application improves the production efficiency of the battery monomer 30, and also improves the reliability of the produced battery monomer 30.

[0063] In some embodiments, as shown in Figure 1 The vibrating assembly 10 includes a vibrating piece 11 and a frame 12. The vibrating piece 11 is connected to the frame 12 and is used to provide a vibration exciting force. The frame 12 is arranged on the side of the clamping assembly 20.

[0064] Optionally, the vibrating piece 11 can be a vibrating motor or the like. The vibration generated by the vibrating piece 11 is transmitted to the frame 12, and the frame 12 transmits the vibration to the clamping assembly 20 and then to the battery monomer 30.

[0065] The vibration member 11 is connected to the frame 12, and the vibration member 11 can be fastened to the frame 12 to quickly and accurately transmit the vibration generated by the vibration member 11 to the clamping assembly 20 via the frame 12.

[0066] The frame 12 is arranged around the clamping assembly 20, and the frame 12 can quickly transmit the vibration force from the periphery of the clamping assembly 20 to the clamping member 21, and then to the battery monomer 30, thereby improving the stability and uniformity of the vibration of the battery monomer 30.

[0067] In some embodiments, the vibration member 11 includes a vibration motor.

[0068] There are various types of finished products of vibration motors on the market, and the price is relatively low. The vibration force provided is stable, which facilitates the manufacturing of the clamping vibration device 1, and is conducive to reducing the production cost of the clamping vibration device 1, and facilitates providing stable and reliable vibration force for the battery monomer 30, to further improve the production efficiency of the battery monomer 30, and is conducive to improving the reliability of the produced battery monomer 30.

[0069] In some embodiments, as shown in Figure 1 The clamping assembly 20 includes a frame 22 and a clamping member 21, the frame 22 has a receiving cavity 22a, and the clamping member 21 is arranged in the receiving cavity 22a and used to clamp the battery monomer 30, and the frame 12 is arranged around the periphery of the frame 22.

[0070] The clamping member 21 can be in the form of a plate or other shapes, and the clamping member 21 is arranged in the receiving cavity 22a. Optionally, the clamping member 21 can be directly or indirectly connected to the frame 22.

[0071] The frame 12 is arranged around the periphery of the frame 22, so that the vibration force of the vibration member 11 is transmitted to the frame 12, and then transmitted to the clamping member 21 along the periphery of the frame 22, and finally transmitted to the battery monomer 30. In this way, it is conducive to improving the stability and uniformity of the vibration force of the clamping vibration device 1 on the battery monomer 30.

[0072] The clamping assembly 20 includes the frame 12 and the clamping member 21, and the frame 12 is arranged around the periphery of the frame 22, so that the frame 12 can be detachably connected to the frame 22. During the production of the battery monomer 30, the clamping assembly 20 can clamp the battery monomer 30, so that the battery monomer 30 is transported together with the clamping assembly 20 from one station to another station without being disassembled, which is conducive to further improving the production efficiency of the battery monomer 30.

[0073] In some embodiments, as shown in Figure 1As shown, the frame 22 includes a bottom plate 221 and a side plate 222, the side plate 222 is arranged around the periphery of the bottom plate 221. The clamping assembly 20 further includes a buffer 26, the buffer 26 is arranged on the side of the bottom plate 221 facing the clamping piece 21, and is used to provide a buffer force for the battery monomer 30.

[0074] Optionally, the material of the buffer 26 can be rubber or other material with a lower elastic modulus.

[0075] The buffer 26 is arranged on the side of the bottom plate 221 facing the clamping piece 21, so that when the clamping piece 21 clamps the battery monomer 30, the excitation force generated by the vibration piece 11 is transmitted to the frame 22 through the frame 12, and then transmitted to the bottom of the battery monomer 30 through the bottom plate 221 of the frame 22 and the buffer 26, and then transmitted to the battery monomer 30 through the buffer 26 on the bottom of the battery monomer 30. In this way, the buffer 26 can filter out part of the unstable vibration force, which is conducive to improving the stability of the vibration of the battery monomer 30. Moreover, the existence of the buffer 26 can reduce the friction between the battery monomer 30 and the bottom plate 221, thereby reducing the damage to the battery monomer 30.

[0076] Therefore, by arranging the buffer 26, it is conducive to improving the stability of the vibration force transmitted to the battery monomer 30, and reducing the friction between the battery monomer 30 and the frame 22 during vibration, and reducing the damage of the frame 22 to the battery monomer 30.

[0077] In some embodiments as shown in Figure 1 and Figure 2 The clamping assembly 20 includes a guide rod 23, the guide rod 23 is supported on the frame 22, and the clamping piece 21 is arranged through the guide rod 23 and can move relative to the guide rod 23.

[0078] The guide rod 23 is supported on the frame 22, and the guide rod 23 can be fixedly connected to the frame 22. The clamping assembly 20 can include one or two guide rods 23, and one clamping piece 21 can be arranged through one or more guide rods 23, so that the clamping piece 21 moves along one or more guide rods 23.

[0079] By arranging the guide rod 23, the guide rod 23 can provide support for the clamping piece 21, which is conducive to improving the clamping stability of the clamping piece 21 to the battery monomer 30. By arranging the clamping piece 21 to pass through the guide rod 23, the guide rod 23 can provide a guide function for the movement of the clamping piece 21. The clamping piece 21 can move along the guide rod 23, so as to adjust the clamping force of the clamping piece 21 to the battery monomer 30. Moreover, during the process of loading the battery monomer 30 into the clamping assembly 20 or disassembling the battery monomer 30 from the clamping assembly 20, the movement of the clamping piece 21 along the guide rod 23 facilitates the loading of the battery monomer 30 into the clamping assembly 20 or the disassembly of the battery monomer 30 from the clamping assembly 20.

[0080] In addition, the sizes of the battery monomers 30 of different specifications are different, and the movement of the clamping members 21 along the guide rods 23 is provided so that the clamping members 21 clamp the battery monomers 30 of different specifications. Thus, the adaptability of the clamping vibration device 1 to the battery monomers 30 of different specifications is improved.

[0081] Therefore, by providing the guide rods 23 and arranging the clamping members 21 to pass through the guide rods 23, the clamping members 21 are provided with support to improve the clamping stability of the clamping members 21 to the battery monomers 30. The distance between the clamping members 21 can be adjusted by the movement of the clamping members 21 along the guide rods 23, so as to adjust the clamping force of the clamping members 21 to the battery monomers 30. While providing vibration to the battery monomers 30, the damage of the clamping members 21 to the battery monomers 30 is reduced. In addition, by moving the clamping members 21 along the guide rods 23, the battery monomers 30 can be conveniently loaded into or unloaded from the clamping assembly 20. The convenience of the installation and removal of the battery monomers 30 is improved, and the adaptability of the clamping vibration device 1 to the battery monomers 30 of different specifications is improved.

[0082] In some embodiments, as shown in Figure 2 , Figure 3 and Figure 4 , the clamping assembly 20 includes a plurality of guide rods 23, and one clamping member 21 passes through the plurality of guide rods 23.

[0083] Optionally, one clamping member 21 can pass through two, three or more guide rods 23. For example, the clamping member 21 can be arranged in a plate shape, and four guide rods 23 can be arranged to pass through four corners of the clamping member 21, respectively.

[0084] It can be understood that by arranging one clamping member 21 to pass through a plurality of guide rods 23, the plurality of guide rods 23 can provide guiding and supporting effects for the clamping member 21 during the movement of the clamping member 21 relative to the guide rods 23. Thus, the stability of the clamping member 21 in operation and the clamping stability of the clamping member 21 to the battery monomers 30 are further improved.

[0085] In some embodiments, as shown in Figure 1 , the clamping assembly 20 includes a plurality of clamping members 21, and the plurality of clamping members 21 are arranged at intervals. The clamping assembly 20 further includes an elastic member 24, and the elastic member 24 passes through the guide rods 23. The elastic member 24 is arranged between at least two adjacent clamping members 21.

[0086] The clamping assembly 20 includes a plurality of clamping members 21, so that the clamping assembly 20 can clamp a plurality of battery monomers 30. The plurality of battery monomers 30 can be simultaneously clamped and vibrated, so as to improve the production efficiency of the battery monomers 30.

[0087] Optionally, the elastic member 24 can be a spring, and the elastic member 24 can be arranged between any two adjacent clamping members 21, or the elastic member 24 can be arranged between part of the adjacent clamping members 21.

[0088] In this way, in the state that the clamping member 21 clamps the battery monomer 30, the elastic member 24 is compressed, and a force counteracting the clamping force is provided for the clamping member 21, which is beneficial to improve the clamping stability of the clamping member 21 to the battery monomer 30. When the battery monomer 30 needs to be disassembled, the clamping force is cancelled, and the clamping member 21 is subjected to the elastic force of the elastic member 24, so that the clamping member 21 is moved along the guide rod 23 away from the battery monomer 30, and the disassembly of the battery monomer 30 is facilitated.

[0089] Therefore, the elastic member 24 is arranged between the at least two clamping members 21, which is beneficial to improve the clamping stability of the clamping member 21 to the battery monomer 30 and facilitate the movement of the clamping member 21 away from the battery monomer 30 under the action of the restoring force of the elastic member 24, and facilitate the disassembly of the battery monomer 30 from the clamping assembly 20.

[0090] In some embodiments, as shown in Figure 1 and Figure 4 , the elastic member 24 is arranged between any two adjacent clamping members 21.

[0091] In this way, the elastic member 24 is arranged between any two adjacent clamping members 21, which is beneficial to further improve the clamping stability of the clamping member 21 to the battery monomer 30 and facilitate the movement of the clamping member 21 away from the battery monomer 30 under the action of the restoring force of the elastic member 24, and facilitate the disassembly of the battery monomer 30 from the clamping assembly 20.

[0092] Optionally, the movement of the clamping member 21 along the guide rod 23 can be manually driven, or a related structure can be arranged to drive the clamping member 21 to move along the guide rod 23, which can be set according to actual needs.

[0093] In some embodiments, as shown in Figure 1 , the clamping assembly 20 further comprises a driving adjusting member 25, and the driving adjusting member 25 is used to drive the clamping member 21 to move along the guide rod 23 to adjust the spacing between the adjacent clamping members 21.

[0094] The driving adjusting member 25 drives the clamping member 21 to move along the guide rod 23 to adjust the spacing between the adjacent clamping members 21, so that the clamping force of the clamping member 21 to the battery monomer 30 can be adjusted, and the installation and disassembly of the battery monomer 30 can be facilitated.

[0095] By setting the driving adjusting member 25, the clamping force can be adjusted more quickly, efficiently and labor-savingly, and the installation and dismounting of the battery monomer 30 can be realized more quickly, efficiently and labor-savingly.

[0096] In some embodiments, as shown in Figure 1 and Figure 4 The driving adjusting member 25 includes a nut 251, the nut 251 is threadedly connected with the frame 22, and the movement of the nut 251 relative to the frame 22 is configured to be able to drive the clamping member 21 to move along the guide rod 23.

[0097] Specifically, the nut 251 is threadedly connected with the frame 22, by twisting the nut 251, the clamping member 21 can be driven to move along the guide rod 23 to the direction close to the battery monomer 30 by the nut 251, and by twisting the nut 251 in the opposite direction, the force of the nut 251 on the driving member is cancelled, and the clamping member 21 can move along the guide rod 23 to the direction away from the battery monomer 30 under the action of the restoring force of the elastic member 24.

[0098] It can be understood that one nut 251 can drive multiple clamping members 21 to move along the guide rod 23, and specifically, the nut 251 drives one clamping member 21, and more clamping members 21 are driven to move along the same guide rod 23 by the one clamping member 21.

[0099] It can be understood that after the clamping member 21 is moved into position, the rotation of the nut 251 is stopped, and a certain locking function can be realized by the nut 251 to maintain the clamping state of the clamping member 21 on the battery monomer 30, without the need to set an additional locking mechanism.

[0100] Therefore, by setting the nut 251, the movement of the clamping member 21 along the guide rod 23 can be realized more quickly and efficiently, and the locking function of the clamping member 21 can be realized by the nut 251 to maintain the clamping force of the clamping member 21 on the battery monomer 30, which is beneficial to simplify the structure of the clamping vibration device 1.

[0103] By setting the heating member, the battery monomer 30 can be heated, which is beneficial to improve the infiltration rate of the electrolyte to the electrode assembly in the process of injecting the electrolyte into the battery monomer 30, and in the process of formation or aging, by heating the battery monomer 30, it is beneficial to improve the rate of gas discharge inside the battery monomer 30.

[0104] In some embodiments, the clamping vibration device 1 further comprises a distance measuring device for measuring the displacement of the vibration of the battery monomer 30.

[0105] Optionally, the distance measuring device can be a range finder or the like, which can be arranged on the upper part of the battery monomer 30.

[0106] By setting the distance measuring device, the vibration amplitude of the battery monomer 30 can be measured to measure the vibration amplitude of the battery monomer 30 in the vibration process, so as to monitor the vibration condition of the battery monomer 30 in real time, so that the vibration amplitude of the battery monomer 30 meets the design value.
