Description

Technical Field

[0001] This invention relates to the field of battery cleaning technology, and more particularly to a battery cleaning device. Background Technology

[0002] During the cleaning process of the cylindrical battery's outer circumference by the battery cleaning device, the battery is first placed on the conveyor roller in the battery cleaning device, and a friction plate is set below the conveyor roller. The friction plate is equipped with a water outlet for spraying cleaning water. The conveyor roller can contact the friction plate under the action of the battery's gravity, so that the water outlet on the friction plate sprays cleaning water onto the outer circumference of the battery for cleaning, ensuring the cleaning effect on the outer circumference of the battery.

[0003] However, due to the direct contact between the conveyor roller and the friction plate, the wear of the conveyor roller is easily aggravated during long-term use, making it impossible for the conveyor roller to fit and rotate, thus affecting the cleaning efficiency of the battery. Summary of the Invention

[0004] The purpose of this invention is to provide a battery cleaning device that provides elastic buffering between the conveying roller and the air knife component, ensuring that the air knife component can adapt to the conveying roller and preventing the problem of accelerated wear of the conveying roller during long-term use.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A battery cleaning apparatus includes a first cleaning assembly for cleaning the outer peripheral surface of a battery, the first cleaning assembly comprising:

[0007] A first support, on which a conveying roller is rotatably mounted;

[0008] The air knife is mounted on the first bracket at one end and located below the conveying roller at the other end. The length of the air knife extends along the conveying direction of the conveying roller. The air knife has multiple water outlets along its length. The conveying roller can elastically contact the air knife under the gravity of the battery.

[0009] As an optional solution, the air knife component includes:

[0010] The system comprises a base, an elastic element, and a friction plate. The base is mounted on the first bracket. The two ends of the elastic element are respectively connected to the base and the friction plate. The friction plate has a plurality of water outlets along its length. The conveying roller can contact the friction plate downward along the Z-axis under the gravity of the battery to compress the elastic element.

[0011] Optionally, the battery cleaning device further includes a second cleaning component, which is spaced apart from the first cleaning component on one side of the first cleaning component along the X-axis. The second cleaning component is used to clean both end faces of the battery. The second cleaning component includes:

[0012] A second support frame is provided, and a conveyor chain is rotatably mounted inside the second support frame. The conveying direction of the conveyor chain is the same as the conveying direction of the conveyor roller.

[0013] A protective fixture, one end of which is engaged with the conveyor chain, and the other end of which is used to place the battery. The protective fixture can be used to cover the explosion-proof valve on the end face of the battery.

[0014] As an optional solution, the protective fixture includes:

[0015] A support base, on which the battery is positioned, and at the bottom end of the support base is a sprocket that meshes with the conveyor chain;

[0016] The adjusting component includes a straight plate and a baffle. The straight plate is installed along the axial direction of the battery to one side of the support base. The baffle is connected to the opposite ends of the straight plate. The baffle is used to cover the explosion-proof valve on the end face of the battery. The axial direction of the battery is parallel to the Y-axis.

[0017] As an optional solution, the top of the support base is provided with an arc-shaped groove, and the battery is snapped into and limited within the arc-shaped groove.

[0018] As an optional feature, the mounting position of the straight plate on the support base is adjustable in the height direction of the support base, and the height direction of the support base is parallel to the Z-axis.

[0019] As an optional feature, the straight plate is provided with a U-shaped hole extending along the Z-axis, and the support base is provided with a mounting hole, and the fastener can be connected to either the mounting hole or the U-shaped hole.

[0020] As an optional solution, the battery cleaning device further includes a transfer assembly, which includes a support frame and a transfer module, the support frame being located between the first cleaning assembly and the second cleaning assembly; the transfer module includes:

[0021] A first driving component and a first mounting base, wherein the fixed end of the first driving component is disposed on the support frame, and the driving end of the first driving component is connected to the first mounting base, and the first driving component is used to drive the first mounting base to move relative to the support frame along the X-axis.

[0022] The second driving member and the second mounting base are provided. The fixed end of the second driving member is disposed on the first mounting base, and the driving end of the second driving member is connected to the second mounting base. The second driving member is used to drive the second mounting base to move along the Z-axis.

[0023] A plurality of gripper cylinders are provided on the second mounting base, and the plurality of gripper cylinders are spaced apart along the X-axis. The gripper cylinders are used to grip the battery on the second cleaning assembly.

[0024] As an optional solution, the transfer module further includes:

[0025] The first limiting member is disposed on the support frame and close to the second cleaning component. When the second driving member drives the second mounting seat to move downward along the Z-axis, the second mounting seat can abut against the top surface of the first limiting member so that the gripper cylinder can grip the battery on the second cleaning component.

[0026] The second limiting member is disposed on the support frame and close to the first cleaning component. When the first driving member drives the first mounting base to move relative to the support frame along the X-axis to the first cleaning component, and the second driving member drives the second mounting base to move downward along the Z-axis, the second mounting base can abut against the top surface of the second limiting member, so that the gripper cylinder places the gripped battery on the first cleaning component.

[0027] As an option, the top surface of the first limiting member may be flush with or not flush with the top surface of the second limiting member.

[0028] The beneficial effects of this invention are as follows:

[0029] By rotating a conveyor roller for transporting batteries on a first support, the length of the air knife extends along the conveying direction of the conveyor roller. One end of the air knife is mounted on the first support, and the other end is located below the conveyor roller. Multiple water outlets are provided on the air knife along its length. When the battery is placed on the conveyor roller for transport, the conveyor roller can elastically contact the air knife under the weight of the battery, so that the water outlets on the air knife spray cleaning water onto the outer circumference of the battery for cleaning, ensuring the cleaning effect on the outer circumference of the battery. Because the conveyor roller elastically contacts the air knife under the weight of the battery, there is an elastic buffer between the conveyor roller and the air knife, ensuring that the air knife can adapt to the conveyor roller. Compared with the direct contact between the conveyor roller and the air knife, the problem of accelerated wear of the conveyor roller is not likely to occur during long-term use, ensuring that the conveyor roller can fit against the air knife and rotate on the air knife, thereby ensuring the cleaning efficiency of the battery.

[0042] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0043] Any feature disclosed in this specification, unless specifically stated otherwise, may be replaced by other equivalent or similar features. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features. Throughout this specification, the same reference numerals indicate the same elements.

[0044] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0045] This embodiment presents a battery cleaning device that can clean the outer peripheral surface and both end faces of the battery with high cleaning efficiency, without damaging the explosion-proof valves on the battery end faces, thus improving the battery yield. The battery in this embodiment is specifically a cylindrical battery.

[0046] Specifically, such as Figures 1 to 7 As shown, the battery cleaning device includes a first cleaning assembly 1 for cleaning the outer peripheral surface 101 of the battery 10. The first cleaning assembly 1 includes a first support 11 and an air knife 12. A conveying roller 13 is rotatably mounted on the first support 11. One end of the air knife 12 is mounted on the first support 11, and the other end of the air knife 12 is located below the conveying roller 13. The length of the air knife 12 extends along the conveying direction of the conveying roller 13. Multiple water outlets 1221 are provided on the air knife 12 along its length. The conveying roller 13 can elastically contact the air knife 12 under the gravity of the battery 10.

[0047] By rotating a conveyor roller 13 for conveying the battery 10 on the first bracket 11, the length of the air knife 12 extends along the conveying direction of the conveyor roller 13. One end of the air knife 12 is mounted on the first bracket 11, and the other end is located below the conveyor roller 13. Multiple water outlets 1221 are provided on the air knife 12 along its length. When the battery 10 is placed on the conveyor roller 13 for transportation, the conveyor roller 13 can elastically contact the air knife 12 under the gravity of the battery 10, so that the water outlets 1221 on the air knife 12 spray cleaning water onto the outer peripheral surface 101 of the battery 10 for cleaning, ensuring the cleaning effect on the outer peripheral surface 101 of the battery 10.

[0048] Compared with the prior art, the battery cleaning device in this embodiment changes the contact method between the conveying roller 13 and the air knife 12. By making the conveying roller 13 elastically contact the air knife 12 under the gravity of the battery 10, there is an elastic buffer between the conveying roller 13 and the air knife 12, ensuring that the air knife 12 can adapt to the conveying roller 13. Compared with the direct contact between the conveying roller 13 and the air knife 12, the problem of accelerated wear of the conveying roller 13 is not likely to occur during long-term use. This ensures that the conveying roller 13 can fit against the air knife 12 and rotate on the air knife 12, thereby ensuring the cleaning efficiency of the battery 10.

[0049] It is worth noting that the first support 11 mentioned above may specifically include multiple spaced sub-supports or an integral support structure. The specific structure of the first support 11 is not limited here, as long as the conveying rollers 13 can be rotatably arranged on the first support 11, and multiple conveying rollers 13 are provided on the first support 11 to ensure the continuity of the conveying of the battery 10 on the first support 11.

[0050] Specifically, such as Figure 3 and Figure 4 As shown, the air knife component 12 includes a base 121, an elastic element 123, and a friction plate 122. The base 121 is fixedly mounted on the first bracket 11, meaning the base 121 can remain stationary. The two ends of the elastic element 123 are respectively connected to the base 121 and the friction plate 122. Multiple water outlets 1221 are provided on the friction plate 122 along its length. The conveying roller 13 can contact the friction plate 122 downwards along the Z-axis under the gravity of the battery 10, thereby compressing the elastic element 123. In this embodiment, the elastic element 123 can specifically be a compression spring.

[0051] Specifically, during the transport of the battery 10 on the conveying roller 13, the conveying roller 13 is subjected to the gravity of the battery 10, causing the conveying roller 13 to contact the friction plate 122 below along the Z-axis. At this time, the elastic element 123 is compressed. Since the elastic element 123 below the friction plate 122 can adjust the amount of compression according to the pressure of the friction plate 122, the friction plate 122 and the conveying roller 13 can maintain good contact. This is beneficial for the water outlet 1221 on the friction plate 122 to spray cleaning water to remove water stains on the outer peripheral surface 101 of the battery 10. Furthermore, the elastic element 123 can make the friction plate 122 adapt to the conveying roller 13, reducing the wear caused by the friction plate 122 on the conveying roller 13, ensuring that the conveying roller 13 can fit against the friction plate 122 and rotate on the friction plate 122, thereby ensuring the cleaning efficiency of the battery 10.

[0052] Furthermore, such as Figure 1As shown, the first cleaning assembly 1 also includes a third driving member 14, which is disposed on the first bracket 11. The third driving member 14 is used to drive the conveying roller 13 to rotate, so that the conveying roller 13 conveys the battery 10. In this embodiment, the third driving member 14 can specifically be a motor.

[0053] Specifically, the first cleaning assembly 1 further includes a first cleaning component and a drying component (not shown in the figure). The first cleaning component and the drying component are respectively located above the first support 11, so that the first cleaning component can clean the upper part of the outer peripheral surface 101 of the battery 10, and the drying component can dry the water stains on the outer peripheral surface 101 of the battery 10, thereby ensuring a good cleaning effect on the outer peripheral surface 101 of the battery 10. In this embodiment, the first cleaning component and the drying component can both adopt the existing cleaning and drying structures in batteries, and the first cleaning component and the drying component will not be described in detail here.

[0054] Furthermore, such as Figure 1 and Figure 2 As shown, the battery cleaning device also includes a second cleaning component 2, which is spaced apart from the first cleaning component 1 on one side of the X-axis. The second cleaning component 2 is used to clean the two end faces 102 of the battery 10, thereby ensuring the cleaning effect on the entire battery 10.

[0055] During the cleaning process of the second cleaning component 2 on the end face 102 of the battery 10, the cleaning water may damage the explosion-proof valve on the end face 102 of the battery 10, causing the battery 10 to malfunction and reducing the yield of the battery 10.

[0056] To solve the above problems, such as Figure 5 and Figure 6 As shown, the second cleaning assembly 2 in this embodiment includes a second support 21 and a protective fixture 23; wherein, a conveying chain 22 is rotatably provided inside the second support 21 so that the battery 10 can be conveyed through the conveying chain 22, and the conveying direction of the conveying chain 22 is the same as the conveying direction of the conveying roller 13; one end of the protective fixture 23 is engaged with the conveying chain 22 so that the protective fixture 23 can be conveyed on the conveying chain 22, and the other end of the protective fixture 23 is used to place the battery 10, and the protective fixture 23 can be used to cover the explosion-proof valve of the end face 102 of the battery 10.

[0057] By setting up the protective fixture 23, on the one hand, the battery 10 can be fixed and limited to ensure the stability of the battery 10 on the conveyor chain 22; on the other hand, the explosion-proof valve of the end face 102 of the battery 10 can be blocked, so as to avoid damage to the explosion-proof valve caused by the cleaning water during the cleaning of the end face 102 of the battery 10. This can better protect the explosion-proof valve and thus improve the yield of the battery 10.

[0058] Specifically, such as Figure 5 and Figure 6 As shown, the protective fixture 23 includes a support base 231 and an adjusting component 232. The battery 10 is fixedly positioned on the support base 231. A sprocket 2312, meshing with a conveyor chain 22, is rotatably mounted at the bottom of the support base 231. The meshing motion of the sprocket 2312 on the conveyor chain 22 ensures the linear movement of the entire protective fixture 23 along the X-axis on the second bracket 21. The adjusting component 232 includes a straight plate 2321 and a baffle 2322. The straight plate 2321 is mounted along the axial direction of the battery 10 to one side of the support base 231. Baffles 2322 are connected to opposite ends of the straight plate 2321 on the Y-axis. The baffles 2322 are used to shield the explosion-proof valve on the end face 102 of the battery 10, thus providing better protection for the explosion-proof valve. The axial direction of the battery 10 is parallel to the Y-axis.

[0059] Furthermore, such as Figure 5 and Figure 6 As shown, an arc-shaped groove 2311 is provided at the top of the support base 231. The battery 10 is snapped into and limited within the arc-shaped groove 2311, so that the battery 10 can be fixedly fixed on the support base 231. On the one hand, it makes the installation of the battery 10 on the support base 231 simple and convenient. On the other hand, the arc-shaped groove 2311 can snap into and limit batteries 10 with various outer diameters, which can be used to fix batteries 10 with various outer diameters, and has good versatility and applicability.

[0060] Specifically, in the height direction of the support base 231, the mounting position of the straight plate 2321 on the support base 231 is adjustable, so that the relative position between the baffle 2322 and the end face 102 of the battery 10 is adjustable. This allows the position of the baffle 2322 to be adjusted according to the different outer diameters of the batteries 10, thereby ensuring that the baffle 2322 covers the explosion-proof valves of batteries 10 with different outer diameters. This makes it applicable to the covering of explosion-proof valves of batteries 10 with various outer diameters, resulting in better versatility and applicability. The height direction of the support base 231 is parallel to the Z-axis.

[0061] Furthermore, such as Figure 6 As shown, a U-shaped hole 2323 extending along the Z-axis is provided on the straight plate 2321, and a mounting hole is provided on the support base 231. Fasteners can be connected to either the mounting hole or the U-shaped hole 2323, allowing the mounting position of the straight plate 2321 on the support base 231 along the Z-axis to be adjustable by connecting the fasteners to different positions of the U-shaped hole 2323. Specifically, the fasteners can be bolts. In other embodiments, a combination structure of a slide rail slider and a limiting member can be provided between the support base 231 and the straight plate 2321 to achieve adjustable mounting position of the straight plate 2321 on the support base 231; this is not specifically limited here.

[0062] It is worth noting that, such as Figure 5 and Figure 6 As shown, multiple protective fixtures 23 are provided on the conveyor chain 22 so that multiple batteries 10 can be conveyed simultaneously through each protective fixture 23, so as to ensure the cleaning of the end faces 102 of multiple batteries 10 during the conveying process, thereby improving the cleaning efficiency of the two end faces 102 of the batteries 10.

[0063] Furthermore, such as Figure 1 As shown, the second cleaning assembly 2 also includes a fourth driving member 24, which is mounted on the second bracket 21. The fourth driving member 24 is used to drive the conveyor chain 22 to rotate, so that the conveyor chain 22 conveys the battery 10. In this embodiment, the fourth driving member 24 can specifically be a motor.

[0064] Specifically, the second cleaning assembly 2 further includes second cleaning components (not shown in the figure). The second bracket 21 has second cleaning components disposed on opposite sides of each other along the Y-axis, enabling the two second cleaning components to spray and clean the two end faces 102 of the battery 10 respectively, thereby ensuring a good cleaning effect on the two end faces 102 of the battery 10. In this embodiment, the second cleaning components can adopt the cleaning structure found in existing batteries, and will not be described in detail here.

[0065] Furthermore, such as Figure 1 and Figure 2 As shown, the battery cleaning device also includes a transfer component 3, which is used to transfer the battery 10 after it has been cleaned by the end face 102 on the second cleaning component 2 to the first cleaning component 1, so that the first cleaning component 1 can clean the outer peripheral surface 101 of the battery 10.

[0066] Specifically, such as Figure 7 As shown, the transfer assembly 3 includes a support frame 31 and a transfer module 32; wherein, the support frame 31 is located between the first cleaning assembly 1 and the second cleaning assembly 2, and the transfer module 32 includes a first drive member 321, a first mounting base, a second drive member 322, a second mounting base 324, and a gripper cylinder 323; the fixed end of the first drive member 321 is disposed on the support frame 31, and the drive end of the first drive member 321 is connected to the first mounting base, which is slidably disposed on the support frame 31 along the X-axis. The first mounting base is driven to move relative to the support frame 31 along the X-axis by the fixed end of the second driving component 322, and the driving end of the second driving component 322 is connected to the second mounting base 324. The second driving component 322 is used to drive the second mounting base 324 to move along the Z-axis. A plurality of gripper cylinders 323 are provided on the second mounting base 324. The plurality of gripper cylinders 323 are spaced apart along the X-axis. The gripper cylinders 323 are used to grip the battery 10 on the protective fixture 23 in the second cleaning assembly 2.

[0067] Specifically, when the conveyor chain 22 transports the protective fixture 23 and the battery 10 on it along the X-axis to the transfer assembly 3, the second drive member 322 drives the second mounting base 324 and the gripper cylinder 323 to move downward along the Z-axis to the first preset position, so that the gripper cylinder 323 on the second mounting base 324 can grip the battery 10 in the arc-shaped groove 2311 in the protective fixture 23, thereby achieving the gripping of the battery 10 on the second cleaning assembly 2; and moves the gripper cylinder 323 upward along the Z-axis back to the initial position.

[0068] Subsequently, the first driving member 321 drives the first mounting base, the second driving member 322, the second mounting base 324, and the gripper cylinder 323 to move along the X-axis relative to the support frame 31 above the conveying roller 13 in the first cleaning assembly 1; then, the second driving member 322 drives the second mounting base 324 and the gripper cylinder 323 to move downward along the Z-axis to a second preset position, so that the gripper cylinder 323 on the second mounting base 324 places the gripped battery 10 on the conveying roller 13, so that the conveying roller 13 conveys the battery 10. In this embodiment, the first driving member 321 can specifically be a motor, and the second driving member 322 can specifically be a linear cylinder.

[0069] It is worth noting that, such as Figure 1 , Figure 2 and Figure 7 As shown, in order to improve the conveying and cleaning efficiency of the battery 10, two sets of the first cleaning component 1 and the second cleaning component 2 are respectively provided. The two sets of the first cleaning component 1 are arranged side by side, and the two sets of the second cleaning component 2 are arranged side by side, with one set of the first cleaning component 1 corresponding to one set of the second cleaning component 2. Correspondingly, two transfer modules 32 are also provided. The two transfer modules 32 are located on opposite sides of the support frame 31 on the Y-axis, so that one transfer module 32 can grab the battery 10 on one of the second cleaning components 2 and place it on the first cleaning component 1, thereby ensuring high conveying efficiency, transfer efficiency and cleaning efficiency of the battery 10. That is, the transfer component 3 in this embodiment is a double-row structure with two transfer modules 32.

[0070] It is worth noting that, such as Figure 1 and Figure 2 As shown, one end of the support frame 31 of the transfer assembly 3 is located between the two first supports 11, and the other end of the support frame 31 is located between the two second supports 21, so as to avoid the support frame 31 interfering with the conveying operation of the conveying roller 13 or the conveying chain 22.

[0071] Furthermore, such as Figure 7As shown, the transfer module 32 also includes a first limiting member 325 and a second limiting member 326; wherein, the first limiting member 325 is disposed on the support frame 31 and close to the second cleaning assembly 2. When the second driving member 322 drives the second mounting base 324 to move downward along the Z-axis, the second mounting base 324 can abut against the top surface of the first limiting member 325. At this time, the second mounting base 324 and the gripper cylinder 323 just move downward along the Z-axis to the first preset position, so that the gripper cylinder 323 can accurately grip the battery 10 on the protective fixture 23 in the second cleaning assembly 2; the second limiting member 325 is disposed on the support frame 31 and close to the second cleaning assembly 2. The component 326 is mounted on the support frame 31 and close to the first cleaning assembly 1. When the first driving component 321 drives the first mounting base to move relative to the support frame 31 along the X-axis to the first cleaning assembly 1, and the second driving component 322 drives the second mounting base 324 to move downward along the Z-axis, the second mounting base 324 can abut against the top surface of the second limiting component 326. At this time, the second mounting base 324 and the gripper cylinder 323 move downward along the Z-axis to the second preset position, so that the gripper cylinder 323 can accurately place the gripped battery 10 on the conveying roller 13 in the first cleaning assembly 1.

[0072] By setting the first limiting member 325 and the second limiting member 326, the distance that the second mounting base 324 moves downward along the Z-axis can be limited, which can ensure that the gripper cylinder 323 on the second mounting base 324 can accurately grip the battery 10 or accurately place the battery 10 on the conveying roller 13, thus ensuring the positional accuracy of the battery 10 during the transfer process.

[0073] Specifically, the top surface of the first limiting member 325 may be flush with or not flush with the top surface of the second limiting member 326. In this embodiment, the top surface of the first limiting member 325 is not flush with the top surface of the second limiting member 326, so as to accommodate the conveyor chain 22 and the conveyor roller 13 with uneven top surfaces. That is, the placement height of the battery 10 on the conveyor chain 22 is different from the placement height of the battery 10 on the conveyor roller 13, and the second driving member 322 drives the second mounting base 324 to descend to different heights on the Z-axis in the two separate instances.

[0074] By setting a first limiting member 325 and a second limiting member 326 with uneven top surfaces, batteries 10 at different placement heights can be transferred using a single second driving member 322. This eliminates the need to set the second driving member 322 as a double-stroke linear cylinder or to set two second driving members 322 with different strokes, saving costs and providing better flexibility in transferring batteries 10 at different placement heights. In this embodiment, the first limiting member 325 and the second limiting member 326 can specifically be limiting blocks.

[0075] It is worth noting that the top surfaces of the first limiting member 325 and the second limiting member 326 can also be made flush. This is not specifically limited here and needs to be determined according to the actual transport and placement height of the battery 10.

[0076] The specific working process of the battery cleaning device in this embodiment is as follows:

[0077] First, place the battery 10 in the arc-shaped groove 2311 of the protective fixture 23, and adjust the actual fastening position of the fastener on the U-shaped hole 2323 according to the actual position of the explosion-proof valve on the end face 102 of the battery 10, so as to adjust the height of the baffle 2322 on the Z-axis, so that the baffle 2322 covers the explosion-proof valve on the end face 102 of the battery 10; then place the entire protective fixture 23 on the conveyor chain 22, that is, the sprocket 2312 at the bottom end of the support 231 and the conveyor chain 2312 are connected. 2. Engagement connection, and the fourth drive member 24 drives the conveyor chain 22 to run, so as to transport the protective fixture 23 and the battery 10; as the battery 10 is conveyed along the conveyor chain 22, the second cleaning members on both sides of the second bracket 21 respectively clean the two end faces 102 of the battery 10 to complete the cleaning work of the two end faces 102 of the battery 10, and during the cleaning of the end faces 102 of the battery 10, the baffle 2322 can provide protection for the explosion-proof valve of the end faces 102 of the battery 10.

[0078] Then, when the conveyor chain 22 transports the protective fixture 23 and the battery 10 along the X-axis to the transfer assembly 3, the second drive member 322 drives the second mounting base 324 and the gripper cylinder 323 to move downward along the Z-axis to the first preset position. At this time, the second mounting base 324 abuts against the top surface of the first limiting member 325, so that the gripper cylinder 323 on the second mounting base 324 grips the battery 10 in the arc-shaped groove 2311 in the protective fixture 23. After that, the second drive member 322 drives the second mounting base 324 and the gripper cylinder 323 to move upward along the Z-axis back to their original position. Then, the first drive member 321 drives the first mounting base 23 to move downward along the Z-axis to the first preset position. The second mounting base, the second drive member 322, the second mounting base 324, and the gripper cylinder 323 move together relative to the support frame 31 along the X-axis to above the conveying roller 13 in the first cleaning assembly 1. Then, the second drive member 322 drives the second mounting base 324 and the gripper cylinder 323 together to move downward along the Z-axis to the second preset position. At this time, the second mounting base 324 abuts against the top surface of the second limiting member 326, so that the gripper cylinder 323 on the second mounting base 324 places the gripped battery 10 on the conveying roller 13, and the third drive member 14 drives the conveying roller 13 to run so that the conveying roller 13 conveys the battery 10.

[0079] During the conveying of the battery 10 by the conveying roller 13, the upper part of the outer peripheral surface 101 of the battery 10 is cleaned by the first cleaning component above the first bracket 11, and the water stains on the outer peripheral surface 101 of the battery 10 are dried by the drying component above the first bracket 11. In addition, the water outlet 1221 on the friction plate 122 sprays water onto the lower part of the outer peripheral surface 101 of the battery 10 to complete the cleaning of the outer peripheral surface 101 of the battery 10.

[0080] During the process of conveying the battery 10 by the conveying roller 13, the conveying roller 13 is subjected to the gravity of the battery 10, causing the conveying roller 13 to contact the friction plate 122 below along the Z-axis. At this time, the elastic element 123 is compressed. Since the elastic element 123 below the friction plate 122 can adjust the amount of compression according to the pressure of the friction plate 122, the friction plate 122 and the conveying roller 13 can maintain good contact. This is beneficial for the water outlet 1221 on the friction plate 122 to spray cleaning water to remove water stains on the outer peripheral surface 101 of the battery 10. Furthermore, the elastic element 123 can make the friction plate 122 adapt to the conveying roller 13, reducing the wear caused by the friction plate 122 on the conveying roller 13.

[0081] In this embodiment, the battery cleaning device uses an elastic element 123 between the friction plate 122 and the base 121 to adjust the compression amount of the elastic element 123 according to the pressure of the friction plate 122, so that the friction plate 122 and the conveying roller 13 can maintain good contact and reduce the wear of the conveying roller 13. At the same time, a baffle 2322 is provided to cover the explosion-proof valve of the end face 102 of the battery 10 to provide protection for the explosion-proof valve. Furthermore, by adjusting the installation position of the straight plate 2321 on the support 231, the baffle 2322 can provide protection for the explosion-proof valve of batteries 10 with different outer diameters. Moreover, by providing the first limiting element 325 and the second limiting element 326, the battery 10 can be transferred between different placement heights, which is more flexible.

[0082] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
