Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a liquid injection port cleaning mechanism and cleaning equipment. Background Technology

[0002] During automated battery production, electrolyte needs to be injected. After injection, electrolyte residue often remains around the injection port, which needs to be removed promptly to prevent corrosion of the battery surface. Operators typically use cleaning equipment to clean the electrolyte around the injection port. Related cleaning equipment usually includes multiple wiping mechanisms arranged side-by-side, simultaneously cleaning multiple battery cells on a cell tray. However, when cleaning cells on different cell tray models, the channel spacing varies, making existing cleaning equipment inapplicable and incompatible. In other words, different cleaning equipment is needed to clean cells on different cell tray models, leading to high cleaning costs. Utility Model Content

[0003] The purpose of this application is to provide a liquid injection port cleaning mechanism and cleaning equipment that is compatible with battery cells on battery cell trays with different channel spacing, thereby reducing cleaning costs.

[0004] To achieve the above objectives, in a first aspect, this application provides a liquid injection port cleaning mechanism, comprising:

[0005] Base;

[0006] At least two wiping assemblies, each wiping assembly including a wiping head located at the bottom side of the wiping assembly, the wiping head being configured to clean the injection port, the at least two wiping assemblies being disposed on a base and each capable of moving relative to the base along a first direction, the first direction being perpendicular to the direction from the top side of the wiping assembly to the bottom side of the wiping assembly; and

[0007] An adjustment assembly is connected to the base and is configured to correspond one-to-one with the wiping assembly. The adjustment assembly includes an adjustment rod located on one side of the corresponding wiping assembly along a first direction. The adjustment rod is configured to move relative to the base toward the wiping assembly under the drive of an externally applied force, so as to press the wiping assembly to move to the other side of the first direction.

[0008] As an optional implementation, the first direction includes opposite first and second sides;

[0009] The number of adjustment rods is at least two, and each wiping component and each adjustment component is located on the same side surface of the base;

[0010] One part of the adjustment rod is located on the first side of the wiping assembly and can press against the wiping assembly to move to the second side, while the other part of the adjustment rod is located on the second side of the wiping assembly and can press against the wiping assembly to move to the first side.

[0011] As an optional implementation, the adjustment assembly also includes a mounting base corresponding to the adjustment rod, the mounting base being connected to the base and threadedly connected to the corresponding adjustment rod;

[0012] When the adjusting rod rotates relative to the mounting base, the adjusting rod can move relative to the base in a first direction.

[0013] As an optional implementation, the adjusting rod is a screw;

[0014] The mounting base has a through hole, and a nut is connected to the surface of the mounting base facing the wiping component. The nut is coaxially arranged with the through hole.

[0015] One end of the adjusting rod passes through the through hole and the nut, and is threaded into the nut.

[0016] As an alternative implementation, the mounting base has an adjustable connection position relative to the base along a first direction.

[0017] As an optional implementation, the base includes a mounting plate, the surface of the mounting plate in the thickness direction being a first surface, and both the wiping assembly and the adjustment assembly are disposed on the first surface;

[0018] The first surface is also provided with at least two scales, which are set one-to-one with the wiping components, and the scales are used to mark the relative positions of the corresponding wiping components and the base.

[0019] As an optional implementation, the first surface is parallel to the first direction;

[0020] Each wiping assembly is arranged at intervals along a first direction on the first surface. At least a portion of the two scales corresponding to the two wiping assemblies located closest to the edge of the first surface along the first direction are located between the two wiping assemblies, and are staggered along a second direction from the top side of the wiping assembly to the bottom side of the wiping assembly.

[0021] As an optional implementation, the liquid inlet cleaning mechanism also includes a locking component; the locking component is disposed on the base, and the locking component is disposed in a one-to-one correspondence with the wiping component, the locking component being used to lock the corresponding wiping component to the base.

[0022] As an optional implementation, the locking assembly includes a locking member and a fastener. The locking member is fixedly connected to the corresponding wiping assembly, and the locking member is provided with an oblong hole, the length direction of which is along a first direction.

[0023] The fastener passes through the waist-shaped hole and connects to the base.

[0024] Secondly, this application also discloses a cleaning device, including the inlet cleaning mechanism described above.

[0025] Compared with the prior art, the beneficial effects of this application are:

[0026] In this application, by providing at least two wiping components, and the wiping head on the bottom side of the wiping component is configured to clean the liquid injection port, the at least two wiping components can simultaneously clean the liquid injection ports of at least two cells arranged in a row.

[0027] Furthermore, by providing adjustment components corresponding one-to-one with the wiping components, each adjustment component includes an adjustment rod located on one side of the corresponding wiping component along a first direction. The adjustment rod is configured to move relative to the base towards the wiping component under the drive of an externally applied force, thereby pressing the wiping component to move to the other side of the first direction. Thus, the adjustment rod can press the wiping component against one side of the wiping component, allowing the wiping component to move steplessly to the other side. If adjustment rods are provided on both sides of the wiping component along the first direction, the position of the wiping component on both sides of the first direction can be adjusted. In other words, the adjustment components are constructed to adjust the relative position of the corresponding wiping component and the base along the first direction, where the first direction is perpendicular to the direction from the top side of the wiping component to the bottom side of the wiping component. For each wiping component, its relative position with the base along the first direction can be adjusted by the corresponding adjustment component; that is, for adjacent wiping components, the spacing between them along the first direction can be adjusted. When the liquid injection port cleaning mechanism cleans the cells on the cell tray, as long as the first direction is aligned with the row direction of the cells to be cleaned, adjusting the spacing of each wiping component in the first direction can accommodate changes in the channel spacing of the cell tray. For example, when a change in the cell tray model causes a change in the channel spacing, the spacing of each cell along the row direction changes. Simply adjusting the relative position of each wiping component in the first direction, aligning each component with the corresponding cell, is sufficient to clean that cell. Therefore, the liquid injection port cleaning mechanism of this application is compatible with cells on cell trays with different channel spacings, thus reducing cleaning costs.

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0050] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0051] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0052] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0053] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0054] During automated battery production, after the battery cells and cover are sealed, electrolyte is injected into the battery through the injection port on the cover. After injection, electrolyte residue often remains around the injection port. This residue can corrode the battery casing, and crystallization can cause weld spalling during battery sealing. Therefore, after injection, operators typically use cleaning equipment to thoroughly clean the electrolyte around the injection port.

[0055] Cleaning equipment in related technologies typically includes a base and multiple wiping mechanisms arranged side by side. The wiping mechanisms are fixedly connected to the base and spaced apart from each other. The spacing between adjacent wiping mechanisms can correspond to the spacing between rows of battery cells on the battery cell tray. In this way, during the cleaning process, multiple wiping mechanisms can simultaneously wipe and clean the entire row of battery cells on the battery cell tray.

[0056] However, when cleaning cells on different types of cell trays, the varying channel spacing of these trays leads to incompatibility and unsuitability of the relevant cleaning equipment. Cleaning cells on different types of cell trays typically requires replacing different cleaning equipment or modifying existing equipment by replacing large components, which is not only time-consuming but also results in high cleaning costs.

[0057] In view of this, this application provides a liquid inlet cleaning mechanism and cleaning device. By setting adjustment components corresponding one-to-one with the wiping components, the adjustment components include adjustment rods located on one side of the corresponding wiping component along a first direction. The adjustment rods are configured to move relative to the base towards the wiping component under the drive of an externally applied force, thereby pressing the wiping component to move to the other side of the first direction. Thus, the adjustment rods can press the wiping component against one side of the wiping component, allowing the wiping component to move steplessly to the other side. With adjustment rods on both sides of the wiping component along the first direction, the position of the wiping component on both sides of the first direction can be adjusted. In other words, the adjustment components are constructed to adjust the relative position of the corresponding wiping component and the base along the first direction. For each wiping component, its relative position with the base along the first direction can be adjusted by the corresponding adjustment component, thereby adjusting the spacing between them. In actual use, when encountering different types of battery cell trays, each wiping component can be adjusted to align with the corresponding battery cell according to the different battery cell spacing, thus achieving cleaning of the corresponding battery cell. Therefore, the liquid inlet cleaning mechanism of this application can be compatible with cells on cell trays with different channel spacing, thus reducing cleaning costs.

[0058] The following will describe the scheme of this application in detail with reference to the accompanying drawings.

[0059] Please see Figure 1 , Figure 2 , Figure 3, Figure 1 This is a schematic diagram of the liquid inlet cleaning mechanism provided in this application embodiment applied to a cleaning device. Figure 2 yes Figure 1 A magnified view of a portion at point A. Figure 3 yes Figure 1 A magnified view of a portion of point B.

[0060] The liquid inlet cleaning mechanism 100 provided in this application includes a base 60, at least two wiping assemblies 10, and an adjusting assembly 20. Each wiping assembly 10 includes a wiping head 11 located at its bottom side, configured to clean the liquid inlet. At least two wiping assemblies 10 are disposed on the base 60 and are all movable relative to the base 60 along a first direction F, which is perpendicular to the direction from the top side of the wiping assembly 10 to the bottom side. The adjusting assembly 20 is connected to the base 60 and is configured to correspond one-to-one with each wiping assembly 10. The adjusting assembly 20 includes an adjusting rod 30 located on one side of the corresponding wiping assembly 10 along the first direction F. The adjusting rod 30 is configured to move relative to the base 60 towards the wiping assembly 10 under the drive of an externally applied force, thereby pressing the wiping assembly 10 to move towards the other side of the first direction F.

[0061] In this application, by providing at least two wiping components 10, and the wiping head 11 on the bottom side of the wiping component 10 is configured to clean the liquid injection port, the at least two wiping components 10 can simultaneously clean the liquid injection ports of at least two battery cells arranged in a row.

[0062] Furthermore, by providing adjustment components 20 corresponding one-to-one with the wiping components 10, the adjustment components 20 include adjustment rods 30 located on one side of the corresponding wiping component 10 along the first direction F. The adjustment rods 30 are configured to move relative to the base 60 towards the wiping component 10 under the drive of an externally applied force, thereby pressing the wiping component 10 to move towards the other side of the first direction F. Thus, the adjustment rods 30 can press against the wiping component 10 on one side, allowing the wiping component 10 to move steplessly to the other side. If adjustment rods 30 are provided on both sides of the wiping component 10 along the first direction F, the position of the wiping component 10 on both sides along the first direction can be adjusted. In other words, the adjustment components 20 can adjust the relative position of the corresponding wiping component 10 and the base 60 along the first direction F, where the first direction F is perpendicular to the direction from the top side of the wiping component 10 to the bottom side of the wiping component 10. Each wiping assembly 10 can be adjusted relative to the base 60 along the first direction F via a corresponding adjusting assembly 20. In other words, the spacing between adjacent wiping assemblies 10 along the first direction F can be adjusted. When the filling port cleaning mechanism 100 cleans the cells on the cell tray, as long as the first direction F is aligned with the row direction of the cells to be cleaned, adjusting the spacing of each wiping assembly 10 along the first direction F can accommodate changes in the channel spacing of the cell tray. For example, when a change in the cell tray model causes a change in the channel spacing, the spacing of each cell along the row direction changes. Simply adjusting the position of each wiping assembly 10 along the first direction F to align each wiping assembly 10 with the corresponding cell achieves cleaning of that cell. Therefore, the filling port cleaning mechanism 100 of this application is compatible with cells on cell trays with different channel spacings, thus reducing cleaning costs.

[0063] In this application, for ease of explanation, the direction from the top side of the wiping assembly 10 to the bottom side of the wiping assembly 10 is defined as the second direction S, and the direction perpendicular to both the first direction F and the second direction S is defined as the third direction T.

[0064] Please continue reading. Figure 1 The base 60 may include a mounting plate 61 and a support leg 62. The mounting plate 61 is connected to the support leg 62, which is used to connect to the frame 210 of the cleaning equipment 200. For example, the support leg 62 may be movable relative to the frame 210 along a third direction T, where the third direction T may be the column direction of the battery cells. In this way, after cleaning the battery cells in the same row, the multiple wiping assemblies 10 may move along the third direction T to align with the next row of battery cells for cleaning.

[0065] Figure 4 This is a schematic diagram of the wiping component 10 in the liquid inlet cleaning mechanism 100 provided in this application embodiment. Please refer to... Figure 1 and Figure 4 Referring to the reference, the bottom side of the wiping assembly 10 refers to the lowest position of the wiping assembly 10 in the height direction of the cleaning equipment during normal use. Generally, during cleaning, the wiping head 11 is positioned above the liquid inlet of the battery cell. Therefore, the wiping assembly 10 is usually located above the battery cell, and the liquid inlet of the battery cell is cleaned by the wiping head 11 located on the bottom side of the wiping assembly 10. The direction from the top side of the wiping assembly 10 to the bottom side of the wiping assembly 10 can be, for example, the direction from top to bottom in the height direction of the cleaning equipment. As mentioned above, during the cleaning process, multiple wiping assemblies 10 need to move along a third direction T under the drive of the base 60 to clean the battery cells in different rows. Here, the first direction F can be perpendicular to the third direction T. In other words, the third direction T can be along the column direction of the battery cells in the battery cell tray, and the first direction F can be along the row direction of the battery cells in the battery cell tray.

[0066] The number of wiping components 10 can be set as needed. In this application, we take a case where the number of wiping components 10 is 3 as an example. The same applies to other cases where the number of wiping components 10 is 3, and we will not repeat them here.

[0067] Please continue reading. Figure 4 The wiping assembly 10 may include a wiping head 11, which is configured to clean the liquid injection port. In this application, each wiping assembly 10 can clean one battery cell. Please refer to [link to relevant documentation]. Figure 4 The wiping assembly 10 may also include a base plate 12 and a rotary drive assembly 13. The base plate 12 is used to connect to the base 60, the rotary drive assembly 13 is rotatably connected to the base plate 12 and fixedly connected to the wiping head 11, and the rotary drive assembly 13 is configured to drive the wiping head 11 to rotate relative to the base plate 12 to perform rotary wiping on the injection port.

[0068] In this application, at least two wiping components 10 are disposed on the base 60 and are all movable relative to the base 60 in the first direction F. For example, a base plate 12 may be guided and connected to the base 60 and be able to reciprocate relative to the base 60 in the first direction F.

[0069] Please combine Figure 1 and Figure 2 By referring to the settings, the adjustment components 20 and the wiping components 10 are set one-to-one, so that the relative position of each wiping component 10 with respect to the base 60 along the first direction F can be adjusted.

[0070] Located in Figure 2Taking the wiping assembly 10 on the far left of the diagram as an example, the adjusting rod 30 corresponding to this wiping assembly 10 can be located on one side of the wiping assembly 10 along the first direction F, such as the left side. Thus, when the adjusting rod 30 moves along the first direction F to the other side, such as the right side, it can press against the wiping assembly 10 as it moves to the right along the first direction F. Alternatively, the adjusting rod 30 can be located on the other side of the wiping assembly 10 along the first direction F, such as the right side. Thus, when the adjusting rod 30 moves along the first direction F to one side, such as the left side, it can press against the wiping assembly 10 as it moves to the left along the first direction F. Figure 2 In the example, some adjustment rods 30 are located on the left side of the corresponding wiping assembly 10 along the first direction F, and other adjustment rods 30 are located on the right side of the corresponding wiping assembly 10 along the first direction F. This allows for stepless adjustment of the spacing between adjacent wiping assemblies 10. Alternatively, the adjustment rods 30 can be provided only on one side of the corresponding wiping assembly 10, with no adjustment rod 30 on the other side. For example, the adjustment rods 30 can be provided only on the left side of the corresponding wiping assembly 10, or only on the right side of the corresponding wiping assembly 10. This allows adjustment of the movement of the wiping assembly 10 relative to the base 60 along one side of the first direction F, and also adjusts the relative position of adjacent wiping assemblies 10.

[0071] Please continue reading. Figure 2 In some embodiments, the first direction F includes opposite first sides F1 and second sides F2. Each wiping assembly 10 and each adjusting assembly 20 is disposed on the same side surface of the base 60. A portion of the adjusting rods 30 are located on the first side F1 of the wiping assembly 10 and can press against the wiping assembly 10 to move towards the second side F2; another portion of the adjusting rods 30 are located on the second side F2 of the wiping assembly 10 and can press against the wiping assembly 10 to move towards the first side F1. With this configuration, each wiping assembly 10 can move relative to the base 60 along the first direction F towards the second side F2 under the drive of a portion of the adjusting rods 30, and can also move relative to the base 60 along the first direction F towards the first side F1 under the drive of the other portion of the adjusting rods 30. That is, each wiping assembly 10 can reciprocate relative to the base 60 along the first direction F, which makes it easier to flexibly adjust the spacing between adjacent wiping assemblies 10.

[0072] Of course, this application uses the example of two adjusting rods 30 included in the adjusting assembly 20, with the two adjusting rods 30 located on the first side F1 and the second side F2 of the wiping assembly 10, respectively. The same applies to other cases where the number of adjusting rods 30 is different, and will not be described in detail here. In specific implementation, the adjusting rods 30 can press against the side edge of the base plate 12 of the wiping assembly 10 along the first direction F.

[0073] Please see Figure 5 , Figure 6 and Figure 7 , Figure 5 This is a schematic diagram of the structure of the liquid inlet cleaning mechanism 100 provided in the embodiment of this application. Figure 6 yes Figure 5 A magnified view of a portion of point C. Figure 7 This is a top view of the liquid inlet cleaning mechanism 100 provided in this embodiment of the application.

[0074] In some embodiments, the adjusting assembly 20 further includes a mounting base 40 corresponding to the adjusting rod 30. The mounting base 40 is connected to the base 60 and threadedly connected to the corresponding adjusting rod 30. When the adjusting rod 30 rotates relative to the mounting base 40, the adjusting rod 30 can move relative to the base 60 along a first direction F. Because the adjusting rod 30 and the mounting base 40 are threadedly connected, when the adjusting rod 30 is driven by an external force and is twisted relative to the mounting base 40, the mounting base 40 remains fixed relative to the base 60, allowing the adjusting rod 30 to move relative to the base 60 along the first direction F. This configuration simplifies the adjustment operation of the adjusting rod 30.

[0075] For example, the mounting base 40 can be constructed as a plate, one end of the mounting base 40 can be connected to the base 60, so that the mounting base 40 is cantilevered to the base 60, and the adjusting rod 30 can be disposed through the cantilever end of the mounting base 40, and the axial direction of the adjusting rod 30 can be along the first direction F.

[0076] In some embodiments, the mounting base 40 has an adjustable connection position relative to the base 60 along a first direction F. Thus, during adjustment, the relative positions of the mounting base 40 and the base 60 can be adjusted so that the wiping assembly 10 is initially roughly aligned with the injection port, and then the position of the wiping assembly 10 can be precisely adjusted by adjusting the relative displacement of the adjusting rod 30 and the base 60. For example, the mounting plate 61 may have a first positioning hole 611, and the corresponding position on the mounting base 40 may have a second positioning hole 402. The mounting base 40 can be connected to the first positioning hole 611 by a fastener passing through the second positioning hole 402, thereby connecting the mounting base to the base 60.

[0077] The first positioning holes 611 on the mounting plate 61 can be configured into multiple groups as needed. These multiple groups of first positioning holes 611 can be arranged at intervals along the first direction F, for example. Thus, when fasteners are connected to different groups of first positioning holes 611, the mounting base 40 can be connected to different positions on the mounting plate 61 along the first direction F. Figure 6In the example, each mounting base 40 corresponds to five sets of first positioning holes 611 for illustration. Each set of first positioning holes 611 includes two first positioning holes 611. These five sets of first positioning holes 611 can be set at equal intervals along the first direction F, or the interval can be set according to actual needs. By connecting the mounting base 40 to different sets of first positioning holes 611, the relative position of the mounting base 40 on the mounting plate 61 can be adjusted.

[0078] In some embodiments, the adjusting rod 30 can be a screw. That is, the outer circumferential surface of the adjusting rod 30 can be provided with external threads. The mounting base 40 is provided with a through hole 401, and a nut 50 is connected to the surface of the mounting base 40 facing the wiping assembly 10. The nut 50 is coaxially arranged with the through hole 401. One end of the adjusting rod 30 passes through the through hole 401 and the nut 50 and is threadedly connected to the nut 50. As one possible implementation, the through hole 401 is provided with internal threads. In this way, the adjusting rod 30 is threadedly connected to both the through hole 401 and the nut 50, which can increase the length of the threaded connection between the adjusting rod 30 and the mounting base 40 and ensure the stability of the adjusting rod 30 during the tightening process. In another possible implementation, the through hole 401 is not provided with threads. In this way, the adjusting rod 30 is only threadedly connected to the nut 50. In this way, it is only necessary to open a smooth hole as the through hole 401 in the mounting base 40 and set the nut 50 on the mounting base 40 by welding or other means to achieve the threaded connection between the adjusting rod 30 and the mounting base 40. The processing of the mounting base 40 is relatively convenient.

[0079] As mentioned earlier, there can be two adjusting rods 30. Correspondingly, there are also two mounting bases 40 and two nuts 50. Please refer to the following: Figure 6 , Figure 7 The two adjusting rods 30 are defined as the first adjusting rod 31 and the second adjusting rod 32, the two mounting seats 40 are defined as the first mounting seat 41 and the second mounting seat 42, and the two nuts 50 are defined as the first nut 51 and the second nut 52. Thus, the first adjusting rod 31 is located on the first side F1 of the wiping assembly 10 and can press against the wiping assembly 10 to move towards the second side F2, and the second adjusting rod 32 is located on the second side F2 of the wiping assembly 10 and can press against the wiping assembly 10 to move towards the first side F1.

[0080] The first mounting base 41 is connected to the base 60 and is located on the first side F1 of the corresponding wiping assembly 10. The first mounting base 41 is threadedly connected to the first adjusting rod 31. When the first adjusting rod 31 rotates relative to the first mounting base 41, the first adjusting rod 31 can move relative to the base 60 in the first direction F toward the second side F2. The first nut 51 is connected to the surface of the first mounting base 41 facing the second side F2.

[0081] The second mounting base 42 is connected to the base 60 and located on the second side F2 of the corresponding wiping assembly 10. The second mounting base 42 is threadedly connected to the second adjusting rod 32. When the second adjusting rod 32 rotates relative to the second mounting base 42, the second adjusting rod 32 can move relative to the base 60 in the first direction F toward the first side F1. The second nut 52 is connected to the surface of the second mounting base 42 facing the first side F1.

[0082] In some embodiments, as described above, the base 60 includes a mounting plate 61, with one surface of the mounting plate 61 in the thickness direction being a first surface 610. Both the wiping assembly 10 and the adjusting assembly 20 are disposed on the first surface 610. The first surface 610 also has at least two scales 63, each scale 63 corresponding to a wiping assembly 10, and the scales 63 are used to calibrate the relative positions of the corresponding wiping assembly 10 and the base 60. This arrangement allows for precise control of the relative position of the wiping assembly 10 relative to the base 60 and facilitates accurate determination of the distance between two adjacent wiping assemblies 10. For example, the mounting plate 61 may have a calibration pointer (not shown). When the wiping assembly 10 moves, the calibration pointer points to different positions on the scales 63. The relative positions of the wiping assembly 10 and the base 60 can be obtained by observing and determining the pointer's indication of the scale on the scales 63.

[0083] exist Figure 6 In the example, each wiping component 10 is provided with a scale 63, which can be located on the bottom side of the mounting base 40 and extend along the first direction F.

[0084] Furthermore, please combine Figure 1 and Figure 6 Referring to some embodiments, the first surface 610 is parallel to the first direction F. Wiping assemblies 10 are spaced apart on the first surface 610 along the first direction F. At least a portion of the two scales 63 corresponding to the two wiping assemblies 10 closest to the edge of the first surface 610 along the first direction F are located between the two wiping assemblies 10, and are staggered along a second direction S from the top side of the wiping assembly 10 to the bottom side of the wiping assembly 10. For example, in Figure 1 In the example, located Figure 1 The two wiping components 10 on the second side F2 in the diagram have a scale 63 corresponding to one of them (the second one from the right) located on the second side F2 of the wiping component 10, and a scale 63 corresponding to the other wiping component 10 (the rightmost one) located on the first side F1 of the wiping component 10. That is, the scales 63 corresponding to the two wiping components 10 are arranged adjacent to each other and staggered in the second direction S, that is, the two scales 63 are set at different heights, so that the scale 63 corresponding to the rightmost wiping component 10 does not take up too much space.

[0085] In this application, as described above, the wiping assembly 10 and the base 60 can be guidedly connected along a first direction F. In some embodiments, the base 60 further includes a guide assembly 70. The guide assembly 70 includes a cooperating slide rail 71 and a slider 72. The slide rail 71 is connected to the first surface 610 and extends along the first direction F, and each wiping assembly 10 is connected to the slider 72. This arrangement limits the movement of the wiping assembly 10 relative to the base 60 to the first direction F.

[0086] Please see Figure 8 , Figure 8 This is a schematic diagram of the locking component 80 in the inlet cleaning mechanism 100 provided in this application embodiment. In some embodiments, the inlet cleaning mechanism 100 further includes a locking component 80. The locking component 80 is disposed on the base 60, and the locking component 80 is disposed in a one-to-one correspondence with the wiping component 10. The locking component 80 is used to lock the corresponding wiping component 10 to the base 60.

[0087] Exemplarily, the locking assembly 80 includes a locking member 81 and a fastener (not shown). The locking member 81 is connected to the corresponding wiping assembly 10, and has an oblong hole 810. The fastener passes through the oblong hole 810 and is connected to the base 60 to lock the corresponding wiping assembly 10 relative to the base 60. The oblong hole 810 can extend along a first direction F, allowing the fastener to be adjusted along the oblong hole 810 in the first direction F, thereby changing the connection position of the locking member 81 to the base 60 in the first direction F. The locking member 81 may include two connecting pieces 811 arranged at an included angle, one connecting piece 811 being fixedly connected to the wiping assembly 10, and the other connecting piece 811 being connected to the base 60. The oblong hole 810 is formed in the other connecting piece 811.

[0088] Please see Figure 1 This application also discloses a cleaning device 200, including the inlet cleaning mechanism 100 as described above. It is understood that the cleaning device 200 has the inlet cleaning mechanism 100 described above, which can bring the same or similar beneficial effects as the inlet cleaning mechanism 100. For details, please refer to the description of the embodiments of the inlet cleaning mechanism 100, which will not be repeated here.

[0089] Furthermore, the cleaning device 200 may also include a frame 210. The legs of the base 60 are slidably connected to the frame 210 along a third direction T to move the wiping assembly 10 along the third direction T. When the cleaning device 200 performs cleaning, each wiping assembly 10 can be used to wipe the rows of battery cells in the battery cell tray. After wiping, the base 60 moves relative to the frame 210 along the third direction T to align with the next row of battery cells, and continues wiping the next group of battery cells.
