[0038] Currently, judging by market developments, batteries are increasingly being used. They are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace.

[0039] In a battery, several battery cells can be combined to form a module, which is then assembled into a battery pack via a housing or bracket. During the battery cell grouping process, the cells are typically connected using glue. The cells and the housing or bracket are also typically secured together using glue. In this solution, impurities such as oil on the cell surface can cause poor adhesion after the glue is applied to the cell surface and cured, potentially leading to structural failure and compromising battery stability.

[0040] In order to improve the cleanliness of the surface of the battery cell, an embodiment of the present application provides a battery cleaning device, which includes a cleaning cylinder and an electrode device. The cleaning cylinder forms a cleaning channel, and the cleaning channel is provided with openings at both ends along its own axis. The accommodating cavity in the cleaning cylinder is used to communicate with an external gas source. A plurality of nozzles connecting the accommodating cavity and the cleaning channel are provided on the peripheral wall of the cleaning channel. The electrode device is arranged in the accommodating cavity and is used to ionize the gas, so that the gas transported from the external gas source is converted into plasma gas by the electrode device and then sprayed into the cleaning channel from the nozzle, so that the battery surface passing through the cleaning channel can be cleaned by the plasma gas, which is beneficial to improving the cleanliness of the battery.

[0041] The battery cleaning device described in the embodiments of the present application is suitable for cleaning battery cells and components in the battery that need to be bonded. It can remove impurities such as oil stains on the surface of these components, improve the cleanliness of the surface of the battery and the components in the battery that need to be bonded, and enable these components to be stably bonded to external components. Among them, the single battery cell that needs to be cleaned can be directly charged and discharged as a battery. The battery cell 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 to these. The battery cell can be cylindrical, flat, rectangular, or other shapes.

[0042] The battery cleaning device described in the embodiment of the present application can also be used to clean other products that can pass through the cleaning channel, so that the plasma gas injected into the cleaning channel can clean the product.

[0043] The technical solutions of the battery cleaning device and production device provided in the specific embodiments of this application are further explained below.

[0044] An embodiment of the present application provides a battery cleaning device, comprising a cleaning cylinder 1 and an electrode device 2. A receiving chamber 11 is provided within the cleaning cylinder 1. As shown in FIG1 , the cleaning cylinder 1 encloses a cleaning channel 12. The cleaning channel 12 has openings 121 at both ends along its axis. The receiving chamber 11 is configured to communicate with an external gas source. A nozzle 131 is provided on the peripheral wall of the cleaning channel 12, connecting the receiving chamber 11 and the cleaning channel 12. As shown in FIG2 , the electrode device 2 is disposed within the receiving chamber 11 and configured to ionize gas.

[0045] The cleaning cylinder 1 may be a device for cleaning the battery 100 in the battery cleaning device, and can clean the battery 100 passing through it and remove stains on the surface of the battery 100.

[0046] The cleaning channel 12 can be the space enclosed by the cleaning cylinder 1, which is used to pass the battery 100. As the battery 100 passes through the cleaning channel 12, stains on the surface of the battery 100 are also removed, improving the cleanliness of the surface of the battery 100. By providing openings 121 at both ends of the cleaning channel 12 along its own axis, the openings 121 are connected to the cleaning channel 12, allowing the battery 100 to enter the cleaning channel 12 along the axis of the cleaning channel 12 through one opening 121 and exit the cleaning channel 12 through the other opening 121. The battery 100 only needs to move in a single direction along the axis of the cleaning channel 12, which helps to improve the cleaning efficiency of the battery 100.

[0047] The nozzle 131 may be a hole-shaped structure formed on the peripheral wall of the cleaning channel 12. The nozzle 131 may penetrate the peripheral wall of the cleaning channel 12 in the radial direction of the cleaning channel 12 so as to connect the accommodating chamber 11 and the cleaning channel 12.

[0048] The accommodating chamber 11 can be a hollow structure provided within the cleaning cylinder 1. By connecting it to an external gas source, gas delivered from the external gas source can flow into the accommodating chamber 11 and then into the cleaning channel 12 through the nozzle 131. The accommodating chamber 11 can temporarily store the gas delivered from the external gas source. The pressure of the gas obtained by the nozzle 131 connecting the accommodating chamber 11 and the cleaning channel 12 is relatively close and stable, which facilitates the gas to clean the surface of the battery 100 more evenly.

[0049] The electrode assembly 2 can be a device for ionizing gas delivered from an external source, thereby converting the gas delivered from the external source into plasma gas. The electrode assembly 2 can come into contact with the gas delivered from the external source and utilize positive and negative high voltages to ionize the gas (primarily oxygen) to generate a large number of positive and negative ions, thereby producing plasma gas.

[0050] Plasma gas can clean organic matter on the surface of the battery, converting the organic matter into gases such as carbon monoxide and carbon dioxide, which are discharged with the air flow. After the organic matter on the surface of the battery is reduced, the adhesion of the glue on the surface of the battery is enhanced, which is beneficial to improving the bonding strength of the glue to the battery. Since the plasma gas is in a gaseous state, it can be more evenly distributed in the cleaning channel 12 after being filled into the cleaning channel 12, so that the cleaning effect on each surface of the battery located in the cleaning channel 12 is more uniform. The external gas source can be a gas source with a preset pressure, so that the gas ejected from the nozzle 131 can have a certain impact force, which can better remove stains on the surface of the battery 100. For example, the external gas source can be compressed air, so that the electrode device 2 can ionize the oxygen in the air to generate negative air ions.

[0051] Through the above structure, the gas delivered from the external gas source is converted into plasma gas by the electrode device 2 and then sprayed into the cleaning channel 12 from the nozzle 131, so that the stains on the surface of the battery 100 passing through the cleaning channel 12 are in contact with the plasma gas and are removed, which is beneficial to improving the cleanliness of the surface of the battery 100.

[0052] In some embodiments, the battery 100 cleaned by the battery cleaning device may be a battery cell, which may be a cylindrical battery cell, a prismatic battery cell, or other cylindrical battery cell. As the battery cell passes through the cleaning channel 12 along its own axis, the plasma gas ejected from the nozzle 131 of the battery cleaning device can impact the outer circumference of the battery cell, thereby cleaning the battery cell.

[0053] In some embodiments, a plurality of nozzles 131 are arranged at intervals along the circumference of the cleaning channel 12 , and the accommodating cavity 11 is arranged around the outer circumference of the cleaning channel 12 .

[0054] By arranging the accommodating cavity 11 around the periphery of the cleaning channel 12 and arranging the plurality of nozzles 131 at circumferential intervals along the cleaning channel 12, the gas sprayed from the plurality of nozzles 131 toward the battery 100 located in the cleaning channel 12 can cover a larger area of ​​the surface of the battery 100, so that the outer peripheral surface of the battery 100 can be cleaned.

[0055] Illustratively, the plurality of nozzles 131 are arranged at equal intervals along the circumference of the cleaning channel 12 , so that the plurality of nozzles 131 can evenly spray gas toward the peripheral surface of the battery 100 , so that the peripheral surface of the battery 100 can be cleaned more evenly.

[0056] In some embodiments, the cleaning cylinder 1 includes an inner ring 13 and an outer ring 14 . The outer ring 14 is rotatably connected to the inner ring 13 . The inner ring 13 forms a cleaning channel 12 . The nozzle 131 is provided on the inner ring 13 . The outer ring 14 and the inner ring 13 form a receiving chamber 11 .

[0057] Both the inner ring 13 and the outer ring 14 can be annular components within the cleaning cartridge 1. The outer ring 14 is sealed and rotatably mounted on the outer circumference of the inner ring 13, forming a receiving chamber 11 between the two rings. The inner ring 13 is provided with an axially extending hole-like structure, which forms a cleaning channel 12 with openings 121 at both ends. The cleaning channel 12 is used to pass the battery 100. The inner ring 13 is provided with radially extending nozzles 131 on its wall. These nozzles 131 connect the cleaning channel 12 with the receiving chamber 11 surrounding the cleaning channel 12, allowing fluid in the receiving chamber 11 to be sprayed into the cleaning channel.

[0058] By rotatably connecting the outer ring 14 and the inner ring 13 , the inner ring 13 can rotate relative to the outer ring 14 , so that the nozzle 131 provided on the inner ring 13 can rotate around the cleaning channel 12 , so that the gas ejected from the nozzle 131 can clean the entire periphery of the battery 100 .

[0059] For example, the inner ring 13 may be rotatably connected to the outer ring 14 via the bearing 7, so that the inner ring 13 can rotate smoothly relative to the outer ring 14. In some embodiments, the bearing 7 may be either a rolling bearing 7 or a sliding bearing 7, and those skilled in the art may configure the bearing according to actual conditions.

[0060] In some embodiments, as shown in FIG. 4 , the cleaning cartridge 1 further includes a sealing member 16 , which is sealingly and slidingly connected between the outer ring 14 and the inner ring 13 .

[0061] The seal 16 can be a component used to seal the accommodating cavity 11 between the outer ring 14 and the inner ring 13. The seal 16 is sealingly and slidingly connected between the inner ring 13 and the outer ring 14, so that the outer ring 14 is sealed and slidably mounted on the outer peripheral surface of the inner ring 13, facilitating the formation of the accommodating cavity 11 between the two.

[0062] For example, seal 16 may be an annular sealing cover plate, the outer edge of which is fixedly connected to the end surface of outer ring 14, and the inner edge of which is sealingly slidably connected to the outer circumferential surface of inner ring 13. In some embodiments, the inner edge of the sealing cover plate is slidingly and sealingly connected to the outer circumferential surface of inner ring 13 via a sealing rubber ring, thereby improving the sealing performance of seal 16 on accommodating cavity 11 between outer ring 14 and inner ring 13.

[0063] In some embodiments, a plurality of electrode devices 2 are provided, and the plurality of electrode devices 2 are arranged in the accommodating cavity 11 at intervals along the circumference of the cleaning cylinder 1 .

[0064] By disposing multiple electrode devices 2 in the accommodating chamber 11, the gas in the accommodating chamber 11 can be ionized by the multiple electrode devices 2, which is beneficial for increasing the plasma concentration of the gas. By disposing the multiple electrode devices 2 at equal intervals along the circumference of the cleaning cylinder 1, the multiple electrode devices 2 can uniformly ionize the gas in the accommodating chamber 11, making the plasma concentration in the gas uniform.

[0065] In some embodiments, the electrode device 2 can be set at the nozzle 131 in the accommodating chamber 11, so that the gas enters the accommodating chamber 11 after ionization, which is beneficial to increase the plasma concentration of the plasma gas in the accommodating chamber 11 and helps to improve the cleaning effect of the battery cleaning device.

[0066] In some embodiments, the battery cleaning device further includes an input pipe 3 , which is used to connect the accommodating chamber 11 with an external air source.

[0067] The input pipe 3 may be a tubular component for conveying gas provided by an external gas source. The input pipe 3 connects the accommodating chamber 11 with the external gas source so that the gas provided by the external gas source can flow smoothly into the accommodating chamber 11 .

[0068] In some embodiments, the input pipe 3 includes a connecting portion 31 and a lead-out portion 32 that are interconnected. The connecting portion 31 is connected to the accommodating cavity 11 through a joint 15 , and the lead-out portion 32 is used to communicate with an external gas source.

[0069] The connecting portion 31 and the lead-out portion 32 respectively refer to different parts of the input pipe 3 that are interconnected, wherein the connecting portion 31 can be the part connected to the outer ring 14, which is connected to the accommodating chamber 11; the lead-out portion 32 can be the part connected to the external gas source, through which the gas from the external gas source can be transported to the connecting portion 31 so as to be transported to the accommodating chamber 11.

[0070] Exemplarily, the cleaning cylinder 1 further includes a joint 15 , and the connecting portion 31 is connected to the outer ring 14 via the joint 15 , so that the connection of the connecting portion 31 to the outer ring 14 is convenient.

[0071] In some embodiments, the connecting portion 31 is disposed around the outer circumference of the cleaning cylinder 1 along the circumference of the cleaning cylinder 1 , and a plurality of connectors 15 are provided, and the plurality of connectors 15 are disposed at intervals along the circumference of the cleaning cylinder 1 .

[0072] By arranging the connecting portion 31 around the outer circumference of the cleaning cylinder 1 along the circumference of the cleaning cylinder 1, the connecting portion 31 is made annular, so that the distance between the joints 15 of the cleaning cylinder 1 and the connecting portion 31 in its own radial direction is equal, so that the gas in the connecting portion 31 can be evenly input into the accommodating chamber 11 through multiple joints 15.

[0073] In some embodiments, as shown in FIG3 , the battery cleaning device further includes a frame 4 and a driving device 5 , the outer ring 14 is connected to the frame 4 , and the driving device 5 is transmission-connected to the inner ring 13 .

[0074] The frame 4 may be a frame structure in the battery cleaning device, and the outer ring 14 is fixedly connected to the frame 4 , so that the inner ring 13 can rotate relative to the frame 4 by rotating relative to the outer ring 14 .

[0075] The driving device 5 can be a device that can output rotational power outward. By fixing the driving device 5 to the frame 4 and connecting its output end to the inner ring 13 through transmission, the driving device 5 can drive the inner ring 13 to rotate relative to the frame 4.

[0076] In some embodiments, the battery cleaning device further includes a transmission member 6 , which is provided with a through hole extending along the axis of the cleaning channel 12 of the transmission member 6 . The transmission member 6 is connected to the axial end face of the inner ring 13 , and the through hole is communicated with the opening 121 .

[0077] The transmission member 6 can be a component fixedly connected to the inner ring 13 and can rotate synchronously with the inner ring 13. The transmission member 6 is connected to the end face of the inner ring 13 in its own axial direction and protrudes out of the cleaning cylinder 1 along the axial direction of the inner ring 13.

[0078] The through hole can be a hole-like structure in the transmission part 6, which is arranged along the axis of the cleaning channel 12 and is connected to the end face of the inner ring 13 in its own axial direction, so that the through hole is connected with the opening 121. Not only can the through hole extend the cleaning channel 12, which is beneficial to extend the time taken for the battery 100 to pass through the cleaning channel 12 and improve the cleaning effect of the battery 100 in the cleaning channel 12, but it also allows the battery 100 to enter and exit the cleaning channel 12 through the through hole, which facilitates the cleaning of the battery 100.

[0079] In some embodiments, the transmission member 6 passes through the frame 4 , and the output end of the driving device 5 is connected to the transmission member 6 .

[0080] The transmission member 6 protrudes axially along the inner ring 13 toward the outside of the cleaning cylinder 1, and the transmission member 6 extends outside the frame 4, so that the output end of the extended driving device 5 can be connected to the transmission member 6 outside the frame, making the transmission connection between the output end of the driving device 5 and the transmission member 6 convenient.

[0081] For example, the transmission connection between the output end of the driving device 5 and the transmission member 6 can be that the output end of the driving device 5 is connected to the transmission member 6 through a coupling, or that the output end of the driving device 5 is connected to the transmission member 6 through a gear system. Those skilled in the art can make a selection based on actual conditions so that the driving device 5 can be connected to the transmission member 6 through transmission.

[0082] In some embodiments, the driving device 5 includes a driving motor fixed to the frame 4 , and the output shaft of the driving motor is connected to the transmission member 6 through a belt drive, so that the output shaft of the driving motor can drive the transmission member 6 to rotate.

[0083] In some embodiments, as shown in FIG5 , a recessed structure 61 is provided on the outer wall of the transmission member 6, and a belt is disposed in the recessed structure 61. The belt fits against the bottom wall of the recessed structure 61, and the friction between the belt and the bottom wall drives the transmission member 6 to rotate. In the axial direction of the through hole, the belt is limited by the two side walls of the recessed structure 61, reducing the possibility of the belt detaching from the transmission member 6, thereby improving the operating stability of the battery cleaning device.

[0084] Some embodiments of the present application further provide a battery production device, which includes the battery cleaning device provided by the aforementioned technical solution. Since the battery production device includes the battery cleaning device provided by the aforementioned technical solution, the battery 100 produced by the battery production device has a higher degree of cleanliness.

[0085] According to some embodiments of the present application, a battery cleaning device is provided, comprising a cleaning cylinder 1, an electrode assembly 2, an inlet pipe 3, a frame 4, and a drive assembly 5. The cleaning cylinder 1 comprises an inner ring 13 and an outer ring 14 sealingly and slidingly sleeved on the outer circumference of the inner ring 13. The inner ring 13 and the outer ring 14 define a receiving chamber 11. Multiple electrode assemblies 2 are spaced apart circumferentially around the inner ring 13 within the receiving chamber 11 for ionizing gas within the receiving chamber 11. The inner ring 13 is provided with a cleaning channel 12 extending axially therethrough, with openings 121 at both ends. The outer ring 14 and the drive assembly 5 are both fixedly connected to the frame 4, and the drive assembly 5 is drivingly connected to the inner ring 13 to drive the inner ring 13 in rotation. The inner ring 13 is provided with a plurality of circumferentially spaced nozzles 131, which communicate with the cleaning channel 12 and the receiving chamber 11. The connection portion 31 of the input tube 3 is disposed around the outer circumference of the outer ring 14 of the transmission member 6 and is connected to the accommodating chamber 11 via a plurality of connectors 15 spaced apart along the circumference of the outer ring 14. The outlet portion 32 of the input tube 3 is connected to the connection portion 31 and is used to communicate with an external gas source. Compressed gas from the external gas source can be delivered into the accommodating chamber 11 through the input tube 3. Through this structure, the gas delivered from the external gas source is converted into plasma gas by the electrode assembly 2 in the accommodating chamber 11 and then sprayed into the cleaning channel 12 from the nozzle 131.
