[0035] At present, judging from the development of the market situation, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields.

[0036] In a battery, a module can be formed by combining several battery cells, and the module composed of battery cells forms a battery pack through a shell or a bracket. In the process of battery cell grouping, several battery cells are usually connected by glue bonding, and the battery cells and the shell or bracket are also usually fixedly connected by glue bonding. In this scheme, if there are impurities such as oil on the surface of the battery cell, the curing adhesion of the glue applied on the surface of the battery cell will be low, which is easy to cause structural failure and thus affect the stability of the battery.

[0037] In order to improve the cleanliness of the surface of a 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 connect 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.

[0038] The battery cleaning device described in the embodiment of the present application is suitable for cleaning battery cells and parts in the battery that need to be bonded, and can remove impurities such as oil stains on the surface of these parts, improve the cleanliness of the surface of the battery and the parts in the battery that need to be bonded, so that these parts can be stably bonded with external parts. Among them, the single battery cell that needs to be cleaned can be directly used as a battery for charge and discharge, and 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 it is not limited to this. The battery cell can be cylindrical, flat, rectangular or other shapes.

[0039] 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 sprayed into the cleaning channel can clean the product.

[0040] The technical solutions of the battery cleaning device and production device provided in the specific implementation manner of the present application are further explained below.

[0041] The embodiment of the present application provides a battery cleaning device, which includes a cleaning cylinder 1 and an electrode device 2. The cleaning cylinder 1 is provided with a receiving chamber 11, such as Figure 1 As shown, the cleaning cylinder 1 forms a cleaning channel 12, and openings 121 are provided at both ends of the cleaning channel 12 along its own axial direction. The accommodating cavity 11 is used to communicate with an external air source, and a nozzle 131 is provided on the peripheral wall of the cleaning channel 12, and the nozzle 131 connects the accommodating cavity 11 and the cleaning channel 12. Figure 2 As shown, the electrode device 2 is arranged in the accommodating chamber 11 and is used to ionize the gas.

[0042] The cleaning cylinder 1 may be a device for cleaning the battery 100 in the battery cleaning device, and it can clean the battery 100 passing through it and remove stains on the surface of the battery 100 .

[0043] The cleaning channel 12 may be a space surrounded by the cleaning cylinder 1, which is used for the battery 100 to pass through. When the battery 100 passes through the cleaning channel 12, the stains on the surface of the battery 100 are also removed, thereby 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 axial direction, the openings 121 are connected to the cleaning channel 12, so that the battery 100 can enter the cleaning channel 12 from one opening 121 along the axial direction of the cleaning channel 12 and leave the cleaning channel 12 from the other opening 121, so that the battery 100 can move unidirectionally along the axial direction of the cleaning channel 12, which is conducive to improving the cleaning efficiency of the battery 100.

[0044] The nozzle 131 may be a hole-shaped structure opened on the peripheral wall of the cleaning channel 12. The nozzle 131 may penetrate the peripheral wall of the cleaning channel 12 along the radial direction of the cleaning channel 12 so as to connect the accommodating chamber 11 and the cleaning channel 12.

[0045] The accommodating chamber 11 may be a hollow structure provided inside the cleaning cylinder 1. By connecting it to an external gas source, the gas delivered from the external gas source can enter the accommodating chamber 11, and then enter the cleaning channel 12 through the nozzle 131. The accommodating chamber 11 can temporarily store the gas delivered from the external gas source, and 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 is conducive to making the gas clean the surface of the battery 100 more evenly.

[0046] The electrode device 2 can be a device for ionizing the gas delivered from the external gas source, and is used to convert the gas delivered from the external gas source into plasma gas. The electrode device 2 can contact the gas delivered from the external gas source, and use positive high voltage and negative high voltage to ionize the gas (mainly oxygen) to generate a large number of positive ions and negative ions, so as to obtain plasma gas.

[0047] 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 and discharging them with the airflow. 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 improve 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. Exemplarily, the external gas source can be compressed air, so that the electrode device 2 can ionize oxygen in the air to generate negative air ions.

[0048] 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 contacted with the plasma gas and removed, which is beneficial to improving the cleanliness of the surface of the battery 100.

[0049] In some embodiments, the battery 100 cleaned by the battery cleaning device may be a battery cell, and the battery cell may be a cylindrical battery cell, a prismatic battery cell, or other columnar battery cell. The battery cell passes through the cleaning channel 12 along its own axial direction, so that the plasma gas ejected from the nozzle 131 of the battery cleaning device can impact the outer peripheral surface of the battery cell, thereby cleaning the battery cell.

[0050] 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 .

[0051] By arranging the accommodating cavity 11 around the periphery of the cleaning channel 12 and arranging the plurality of nozzles 131 at intervals along the circumference of 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 surface area of ​​the battery 100, so that the outer peripheral surface of the battery 100 can be cleaned.

[0052] Exemplarily, 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 outer peripheral surface of the battery 100 , so that the outer peripheral surface of the battery 100 can be cleaned more evenly.

[0053] 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 disposed on the inner ring 13 , and the outer ring 14 and the inner ring 13 enclose a receiving chamber 11 .

[0054] Both the inner ring 13 and the outer ring 14 can be annular components in the cleaning cylinder 1, wherein the outer ring 14 is sealed and rotatably sleeved on the outer periphery of the inner ring 13 to form a receiving chamber 11 between the outer ring 14 and the inner ring 13. The inner ring 13 is provided with a hole-like structure extending along its own axial direction, and the hole-like structure forms a cleaning channel 12 with openings 121 at both ends, and the cleaning channel 12 is used to pass the battery 100. The wall of the inner ring 13 is provided with a nozzle 131 along its own radial direction, so that the nozzle 131 can connect the cleaning channel 12 and the receiving chamber 11 on the outer periphery of the cleaning channel 12, so that the head in the receiving chamber 11 can be sprayed into the cleaning channel.

[0055] 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 arranged 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 .

[0056] Exemplarily, the inner ring 13 may be rotatably connected to the outer ring 14 via the bearing 7, so that the inner ring 13 rotates 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 set it according to actual conditions.

[0057] In some embodiments, Figure 4 As shown, the cleaning cylinder 1 further comprises a sealing member 16 , which is sealingly and slidably connected between the outer ring 14 and the inner ring 13 .

[0058] 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 slidably 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.

[0059] Exemplarily, the seal 16 may be an annular sealing cover plate, the outer edge of which is fixedly connected to the end face of the outer ring 14, and the inner edge of which is sealingly slidably connected to the outer peripheral surface of the inner ring 13. In some embodiments, the inner edge of the sealing cover plate is slidably and sealingly connected to the outer peripheral surface of the inner ring 13 through a sealing rubber ring, so that the sealing member 16 has a better sealing performance on the accommodating cavity 11 between the outer ring 14 and the inner ring 13.

[0060] 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 .

[0061] By arranging a plurality of electrode devices 2 in the accommodating chamber 11, the gas in the accommodating chamber 11 can be ionized by the plurality of electrode devices 2, which is beneficial to improving the plasma concentration of the gas. By arranging the plurality of electrode devices 2 at equal intervals along the circumference of the cleaning cylinder 1, the plurality of electrode devices 2 can uniformly ionize the gas in the accommodating chamber 11, so that the plasma concentration in the gas is uniform.

[0062] In some embodiments, the electrode device 2 can be arranged 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.

[0063] In some embodiments, the battery cleaning device further includes an input pipe 3, and the input pipe 3 is used to connect the accommodating chamber 11 with an external gas source.

[0064] 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 smoothly flow into the accommodating chamber 11 .

[0065] 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 chamber 11 through a joint 15, and the lead-out portion 32 is used to communicate with an external gas source.

[0066] 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 may be a part connected to the outer ring 14, which is connected to the accommodating chamber 11; the lead-out portion 32 may be a part connected to an 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.

[0067] Exemplarily, the cleaning cylinder 1 further comprises 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.

[0068] In some embodiments, the connection portion 31 is disposed around the outer circumference of the cleaning tube 1 along the circumference of the cleaning tube 1 , a plurality of joints 15 are provided, and the plurality of joints 15 are disposed at intervals along the circumference of the cleaning tube 1 .

[0069] By arranging the connection part 31 around the outer circumference of the cleaning cylinder 1 along the circumference of the cleaning cylinder 1, the connection part 31 is made annular, so that the distance between the joints 15 of the cleaning cylinder 1 and the connection part 31 in its radial direction is equal, so that the gas in the connection part 31 can be evenly input into the accommodating chamber 11 through multiple joints 15.

[0070] In some embodiments, Figure 3 As shown, 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 drivingly connected to the inner ring 13 .

[0071] 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 .

[0072] The driving device 5 can be a device capable of outputting rotational power outward. By fixing the driving device 5 to the frame 4 and connecting its output end to the inner ring 13 in a transmission manner, the driving device 5 can drive the inner ring 13 to rotate relative to the frame 4.

[0073] In some embodiments, the battery cleaning device further comprises a transmission member 6 , which is provided with a through hole penetrating 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 .

[0074] The transmission member 6 may 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.

[0075] The through hole can be a hole-like structure in the transmission member 6, which is arranged along the axis of the cleaning channel 12 and is connected to the axial end face of the inner ring 13, 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 is convenient for cleaning the battery 100.

[0076] 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 .

[0077] 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 out of the frame 4, so that the output end of the extended drive device 5 can be connected to the transmission member 6 outside the frame, making the transmission connection between the output end of the drive device 5 and the transmission member 6 convenient.

[0078] Exemplarily, 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 transmission-connected to the transmission member 6.

[0079] In some embodiments, the driving device 5 includes a driving motor fixed on 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.

[0080] In some embodiments, Figure 5 As shown, a recessed structure 61 is provided on the outer wall of the transmission member 6, and the belt is arranged in the recessed structure 61. The belt fits the bottom wall of the recessed structure 61, and the belt drives the transmission member 6 to rotate through the friction between the belt and the bottom wall. In the axial direction of the through hole, the belt is limited by the two side walls of the recessed structure 61, which reduces the possibility of the belt detaching from the transmission member 6, which is conducive to improving the working stability of the battery cleaning device.
