[0073] Please refer to Figure 2, which is an exploded view of a battery pack 100 provided in some embodiments of the present application. The battery pack 100 includes a housing 110 and a battery module disposed within the housing 110. The battery module includes a plurality of battery cells 3, which are housed within the housing 110. The housing 110 is used to provide a storage space for the battery cells 3 and can have various structures. In some embodiments, the housing 110 can include a first portion 111 and a second portion 112, which overlap with each other and together define a storage space for the battery cells 3. The second portion 112 can be a hollow structure with one end open. The first portion 111 can be a plate-like structure, which overlaps the open side of the second portion 112, so that the first portion 111 and the second portion 112 together define a storage space. Alternatively, the first portion 111 and the second portion 112 can each be a hollow structure with one end open, with the open side of the first portion 111 overlapping the open side of the second portion 112. Of course, the box body 110 formed by the first part 111 and the second part 112 can be in various shapes, such as a cylinder, a cuboid, etc.

[0074] In the battery pack 100, there can be multiple battery cells 3, and the electrode terminal conductive connectors of two battery cells 3 are connected to realize the series connection or parallel connection of the two battery cells 3. Multiple battery cells 3 can be connected in series, in parallel, or in mixed connection. Mixed connection means that multiple battery cells 3 are connected in series and in parallel. Multiple battery cells 3 can be directly connected in series, in parallel, or in mixed connection, and then the whole formed by the multiple battery cells 3 is accommodated in the box 110; of course, the battery pack 100 can also be a battery module formed by first connecting multiple battery cells 3 in series, in parallel, or in mixed connection, and then the multiple battery modules are connected in series, in parallel, or in mixed connection to form a whole, and accommodated in the box 110. The battery pack 100 can also include other structures. For example, the battery pack 100 can also include a busbar component for realizing electrical connection between multiple battery cells 3.

[0075] Each battery cell 3 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 3 can be cylindrical, flat, rectangular, or in other shapes.

[0076] Please refer to Figure 3, which is a schematic diagram of the exploded structure of a battery cell 3 provided in some embodiments of the present application. A battery cell 3 is the smallest unit that makes up a battery pack 100. As shown in Figure 3, a battery cell 3 includes an end cap 32, a housing 35, a cell assembly 34, and other functional components.

[0077] The end cap 32 is a component that fits over the opening of the housing 35 to isolate the internal environment of the battery cell 3 from the external environment. The shape of the end cap 32 can be adapted to the shape of the housing 35 to fit the housing 35. Optionally, the end cap 32 can be made of a material with a certain degree of hardness and strength, such as an aluminum alloy. This prevents the end cap 32 from deforming when subjected to compression or collision, providing the battery cell 3 with greater structural strength and improved safety. Functional components such as electrode terminals 31 can be provided on the end cap 32. The electrode terminals 31 can be used to electrically connect to the battery cell assembly 34 to transmit or receive electrical energy from the battery cell 3. In some embodiments, the end cap 32 can also be provided with a pressure relief mechanism to release internal pressure when the internal pressure or temperature of the battery cell 3 reaches a threshold. The end cap 21 can also be made of a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and this is not particularly limited in the present embodiments. In some embodiments, an insulating member may be provided inside the end cap 32 to isolate the electrical connection components in the housing 35 from the end cap 32 to reduce the risk of short circuit. For example, the insulating member may be made of plastic, rubber, or the like.

[0078] The housing 35 is a component that cooperates with the end cap 32 to form the internal environment of the battery cell 3. This internal environment can accommodate the battery cell assembly 34, electrolyte, and other components. The housing 35 and end cap 32 can be separate components. An opening can be provided in the housing 35, and the end cap 32 is closed over the opening to form the internal environment of the battery cell 3. Alternatively, the end cap 32 and housing 35 can be integrated. Specifically, the end cap 32 and housing 35 can form a common connection surface before other components are inserted into the housing. When the interior of the housing 35 is to be enclosed, the end cap 32 is closed over the housing 35. The housing 35 can be of various shapes and sizes, such as a rectangular parallelepiped, a cylinder, or a hexagonal prism. Specifically, the shape of the housing 35 can be determined based on the specific shape and size of the battery cell assembly 34. The housing 35 can be made of a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and this embodiment of the present application does not impose any particular limitations on this.

[0079] The cell assembly 34 is the component within the battery cell 100 where the electrochemical reaction occurs. The housing 35 may contain one or more cell assemblies 34. The cell assembly 34 is primarily formed by winding or stacking electrode sheets, including positive and negative electrodes, with a separator typically positioned between the positive and negative electrodes.

[0080] The electrode sheets primarily consist of a thin sheet of current collector and an active material coated on the current collector. The active material portions of the positive and negative electrode sheets constitute the main body of the battery cell assembly, while the portions of the positive and negative electrode sheets without active material each constitute a tab 33. The positive and negative tabs can be located together at one end of the main body or separately at both ends. During the charge and discharge process of the battery pack 100, the positive and negative active materials react with the electrolyte, and the tabs 33 connect to the electrode terminals 31 to form a current circuit.

[0081] During battery production, the electrode terminals of multiple battery cells need to be connected via conductive connectors to connect two battery cells in series or in parallel. The electrode terminals of a battery cell and the conductive connectors are typically welded together. Before welding the electrode terminals to the conductive connectors, the electrode terminals of the battery cell need to be cleaned to improve weld quality. Currently, manual cleaning of the electrode terminals is often performed, but manual cleaning of the electrode terminals is prone to poor cleaning consistency and ineffective cleaning results, leading to problems such as punctures and loose welds during welding of the electrode terminals and the conductive connectors.

[0082] In order to improve the problem of poor effect and poor consistency in manual cleaning of electrode terminals, this embodiment provides a battery electrode terminal cleaning device.

[0083] As shown in Figures 4 to 7, the battery electrode terminal cleaning equipment of this embodiment includes a frame 1 and a cleaning device 2. The frame 1 includes a carrying platform 11 for carrying a battery cell 3 whose electrode terminals need to be cleaned; the cleaning device 2 includes a carrying component 21 installed on the frame 1 and a wiping member 22 installed on the carrying component 21. The carrying component 21 is configured to move relative to the carrying platform 11 to drive the wiping member 22 to wipe the electrode terminals 31 of the battery cell 3.

[0084] In this embodiment, the supporting component 21 that supports the wiping member 22 drives the wiping member 22 to move to wipe the electrode terminal 31 of the battery 3. The electrode terminal 31 of the battery cell 3 is cleaned by mechanized equipment, which is beneficial to ensuring the cleaning quality, stability and consistency of the cleanliness, and further beneficial to avoiding quality problems such as welding blowouts or cold welds due to dirt on the electrode terminal 31 and the conductive connector or poor contact between the two when welding the electrode terminal 31 and the conductive connector. Therefore, the battery electrode terminal cleaning equipment of this embodiment is beneficial to improving and ensuring the welding quality of the electrode terminal 31 and the conductive connector.

[0085] In some embodiments, wipe 22 comprises a non-woven fabric.

[0086] In some embodiments, the support member 21 is configured to be movable relative to the frame 1 to drive the wiping member 22 to wipe the electrode terminal 31. Further, the support member 21 can be moved relative to the frame 1 to move the wiping member 22 to another electrode terminal to be wiped. In this embodiment, the same motion mechanism can achieve the functions of wiping and replacing the electrode terminal 31 to be wiped, which helps to simplify the structure of the device and improve the practicality of the device.

[0087] In other embodiments, the support member 21 is configured to rotate relative to the frame 1. The rotation of the support member 21 drives the wiping member 22 to wipe the electrode terminal 31 and also replace the wiping member 22 in contact with the electrode terminal 31. The support member 21 can rotate relative to the frame 1 to achieve the function of wiping the electrode terminal 31 and also replace the wiping member 22 in the wiping position. The same motion mechanism can achieve the functions of wiping and replacing the wiping member 22, which helps to simplify the structure of the device and improve the practicality of the device.

[0088] Referring to Figure 4 , the carrier 21 includes a base 211, a take-up wheel 212, and a release wheel 213. The base 211 is mounted on the frame 1. The take-up wheel 212 is rotatably mounted on the base 211; the release wheel 213 is rotatably mounted on the base 211, with the axis of the release wheel 213 parallel to the axis of the take-up wheel 212. The wiper 22 comprises a belt-like member, one end of which is wound around the take-up wheel 212 and the other end around the release wheel 213.

[0089] In this embodiment, the base 211 is configured to be movable relative to the carrying platform 11 to drive the wiping member 22 to wipe the electrode terminal 31 .

[0090] The supporting platform 11 extends along a first direction to accommodate a plurality of battery cells 3 arranged side by side along the first direction. Electrode terminals 31 are provided at both ends of the battery cells 3 along a second direction perpendicular to the first direction. The axes of the winding wheel 212 and the release wheel 213 are parallel to the first direction. In some embodiments, the winding wheel 212 and the release wheel 213 are arranged side by side along the second direction.

[0091] The reeling wheel 212 and the releasing wheel 213 are both spaced apart from the carrying platform 11. The cleaning device 2 further includes a guide wheel 28 for guiding the wiping member 22 to a position flush with the electrode terminal 31 of the battery cell 3.

[0092] A guide wheel 28 is provided at each end of the battery cell 3 along the second direction. The wiping member 22 located between the two guide wheels 28 at both ends of the battery cell 3 along the second direction wipes the electrode terminals 31 at both ends of the battery cell 3 simultaneously.

[0093] The cleaning device 2 also includes two parallel and spaced guide wheels 28. The wiper 28 extends from the take-up wheel 212 around the two guide wheels 28 to the release wheel 213. The axis of the guide wheel 28 is parallel to the surface to be cleaned of the electrode terminal 31, guiding the wiper 22 into contact with the surface to be cleaned. This facilitates surface contact between the wiper 22 and the surface to be cleaned of the electrode terminal, ensuring cleaning quality.

[0094] The wiping member 22 between the two guide wheels 28 wipes the two electrode terminals 31 located at both ends of the battery. The wiping member 22 can wipe the two electrode terminals 31 of the battery cell 3 at the same time, which is beneficial to improving the cleaning efficiency.

[0095] In this embodiment, the base 211 is configured to be movable relative to the frame 1 in a first direction to wipe the electrode terminals 31, and after wiping the electrode terminals 31 of one battery cell 3, it is moved in the first direction to wipe the electrode terminals 31 of another battery cell 3. After wiping the electrode terminals 31 of one or more battery cells 3, the winding wheel 212 rotates to move a new wiping member 22 to a wiping position corresponding to the electrode terminals of the battery cells 3.

[0096] In other embodiments, the reel 212 rotates to drive the wiping member 22 to wipe the electrode terminals 31 of the battery cell 3. After wiping the electrode terminals 31 of one battery cell 3, the base 211 moves along the first direction to move the cleaning device 2 to another battery cell 3.

[0097] In this embodiment, the cleaning device 2 also includes a pressing mechanism 23 installed on the base 211 and configured to push the strip-shaped component toward the electrode terminal 31. The pressing mechanism 23 presses the wiping member 22 onto the electrode terminal 31 to be cleaned, which is beneficial to ensuring effective contact between the wiping member 22 and the electrode terminal 31, and further beneficial to ensuring the cleaning quality of the electrode terminal 31 by the wiping member 22.

[0098] In some embodiments, the cleaning device 2 includes two pressing mechanisms 23, each configured to push the strip-shaped member toward the electrode terminals 31 at each end of the battery. The two pressing mechanisms 23 are located between the two guide wheels 28. The two pressing mechanisms 23 respectively push the wiping member 22 located between the two guide wheels 28 toward the two electrode terminals 31 of the battery cell 3, so that the cleaning device 2 can simultaneously clean both electrode terminals 31 on a single battery cell 3, thereby improving the cleaning efficiency of the electrode terminals 31.

[0099] In some embodiments, the distance between the two pushing members 23 is adjustable so that the cleaning device 2 can be applied to battery cells 3 with different electrode terminal distances.

[0100] In some embodiments, the cleaning device 2 further includes a first adjustment mechanism 24 that drives the pressing mechanism 23 to move relative to the base 211 to adjust the distance between the two pushing members 23. In some embodiments, the first adjustment mechanism 24 is provided in a one-to-one correspondence with the pressing mechanism 23, so that the cleaning device 2 can be applied to battery cells 3 with different electrode terminals 31.

[0101] Referring to Figure 6, the first adjusting mechanism 24 includes a first screw 241 connected to the pressing mechanism 23, and a screw sleeve 242 threadedly engaged with the first screw 241 and installed on the base 211. During the rotation of the first screw 241, the first screw 241 drives the pressing mechanism 23 to move relative to the base 211 to adjust the position of the pressing mechanism 23.

[0102] In some embodiments, the first adjustment mechanism 24 further includes a first rotating handle 243 connected to the first screw 241 , and the operator can use the first rotating handle 243 to rotate the first screw 241 to drive the pressing mechanism 23 to adjust the position.

[0103] Referring to Figure 5, in some embodiments, the pressing mechanism 23 includes a pressing component 231. In some embodiments, the pressing mechanism further includes a pressing component guide component 232, which is configured to guide the pressing component 231 to move toward the electrode terminal 31. The pressing component guide component 232 can effectively prevent the pressing component from deviating from the electrode terminal 31, thereby effectively ensuring sufficient contact between the wiping member 22 and the electrode terminal, thereby ensuring the wiping quality. The pressing component 231 is used to press the wiping member 22 against the electrode terminal 31 to complete wiping cleaning. Optionally, the pressing component 231 presses the wiping member 22 dipped in cleaning liquid against the electrode terminal 31 to improve the cleaning effect.
