Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a wiping mechanism. Background Technology

[0002] During the production of lithium batteries, electrolyte or other contaminants often remain around the filling port after the cell has been filled with electrolyte. To ensure the battery's sealing performance and the cleanliness of subsequent processes, the filling port must be cleaned before sealing.

[0003] Currently, the industry commonly uses automated equipment with wiping heads to complete this cleaning operation. Clean non-woven fabric or other wiping materials are drawn out from the unwinding assembly and cover the working surface at the bottom of the wiping head. Then, the wiping head moves under the drive mechanism and presses against the battery cell injection port. After wiping, the winding assembly actuates, winding up the used, soiled non-woven fabric and simultaneously pulling out new non-woven fabric from the unwinding assembly to cover the wiping head for the next cleaning. However, during the winding and changing of the non-woven fabric, because the wiping head is usually in a fixed extended position, the non-woven fabric rubs against the surface of the wiping head as it passes the bottom of the wiping head. This friction causes wear on the wiping head itself, shortening its service life. Utility Model Content

Furthermore, by avoiding friction between the wiping head and the wiping parts, it also indirectly prevents secondary contamination of the battery filling port by particles or fiber debris that may be generated due to wear of the wiping head or wiping parts, further improving the reliability of the cleaning process.

Detailed Implementation

[0022] 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 skilled in the art without creative effort are within the scope of protection of this application.

[0023] In this application, the terms "upper," "lower," "top," "bottom," "inner," "vertical," and "horizontal," 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.

[0024] 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.

[0025] Furthermore, the terms "set up," "equipped with," and "connected" 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.

[0026] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (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, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0027] In the lithium battery manufacturing process, the electrolyte injection process involves injecting a measured amount of electrolyte into the battery cell, allowing it to be activated in subsequent formation processes, thus enabling it to charge and discharge. However, during or after the electrolyte injection process, trace amounts of electrolyte or other impurities may remain around the injection port of the battery cell. If these residues are not thoroughly removed, they will affect the sealing effect of the subsequent injection port, potentially leading to leakage and threatening battery safety. Residual electrolyte is corrosive and may cause surface damage to the battery, affecting the quality and consistency of the final product.

[0028] Therefore, the battery cell injection port needs to be cleaned before entering the sealing station. Existing technologies generally employ automated cleaning equipment to accomplish this task. This equipment is equipped with a wiping head and integrates a non-woven fabric unwinding and rewinding system. Clean non-woven fabric is continuously drawn out from the unwinding assembly and smoothly covers the working surface at the bottom of the wiping head. During operation, the wiping head presses firmly against the battery cell injection port. After wiping, the wiping head separates from the battery cell injection port, the rewinding assembly activates, and the soiled non-woven fabric is wound back up. Simultaneously, the unwinding assembly releases a new section of clean non-woven fabric, covering the working surface of the wiping head and preparing it for the next wiping operation.

[0029] However, when the winding assembly pulls the nonwoven fabric, relative sliding and friction occur between the nonwoven fabric and the bottom surface of the wiping head. This continuous, direct friction leads to rapid wear of the wiping head itself (especially the contact surface at the bottom of the wiping head), significantly shortening its lifespan and increasing the frequency of spare parts replacement and the maintenance cost of the cleaning equipment. Furthermore, intense friction may scrape the nonwoven fabric material, generating tiny fiber fragments that may fall onto the surface of the battery cell or into the electrolyte inlet, causing secondary contamination and defeating the purpose of cleaning.

[0030] Based on this, this application discloses a wiping mechanism that drives the wiping head to retract to an avoidance position after wiping and then rolls up the nonwoven fabric, thereby realizing the automatic lifting and lowering of the wiping head and the automatic replacement of the nonwoven fabric. This avoids direct friction between the nonwoven fabric and the wiping head during the winding process and reduces the wear of the wiping head.

[0031] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0032] Please see Figures 1 to 3 , Figure 1 This is one of the structural schematic diagrams of the wiping mechanism 100 provided in the embodiments of this application; Figure 2 This is the second schematic diagram of the wiping mechanism 100 provided in the embodiments of this application; Figure 3 This is one of the structural schematic diagrams of the wiping assembly 2 provided in the embodiments of this application. This application discloses a wiping mechanism 100 for wiping the battery filling port. The wiping mechanism 100 includes: a support 1; and a wiping assembly 2, which is disposed on the support 1. The wiping assembly 2 includes a wiping head 21 and a moving module 22. The wiping head 21 is located at the bottom side of the wiping assembly 2 and is configured to wipe the battery filling port. The moving module 22 is connected to the wiping head 21 and is configured to drive the wiping head 21 vertically. The wiping head 21 moves between a wiping position and an avoidance position; an unwinding assembly 3 is provided on the support 1 and is used to provide a wiping component to the wiping head 21; a winding assembly 4 is provided on the support 1 and is used to retrieve the used wiping component from the wiping head 21; wherein, when the wiping head 21 is in the avoidance position, the wiping head and the wiping component are separated, the unwinding assembly 3 conveys the wiping component to the wiping head 21, and the winding assembly 4 receives the used wiping component that has passed through the wiping head 21.

[0033] The bracket 1 is the basic support structure of the entire wiping mechanism 100. The bracket 1 provides a stable and reliable mounting reference for the wiping assembly 2, the unwinding assembly 3, and the rewinding assembly 4, ensuring that each functional module maintains a precise relative position during high-speed, repetitive industrial operation. The bracket 1 guarantees the overall rigidity and stability of the wiping mechanism 100, preventing a decrease in wiping accuracy due to vibration or deformation under stress, and ensuring consistent cleaning results.

[0034] Furthermore, the bracket 1 can be connected to a cleaning device equipped with a wiping mechanism 100 to integrate the wiping mechanism 100 into the automated cleaning device, thereby improving the efficiency of cleaning the injection port.

[0035] The wiping assembly 2 is the core unit for performing the cleaning function. The wiping head 21 included in the wiping assembly 2 can contact the battery filling port and complete the wiping action. Optionally, the wiping assembly 2 can have various specific implementations. Optionally, the wiping head 21 can have various structural forms and materials to adapt to different cleaning needs and process scenarios. The wiping head 21 can be a rigid block made of wear-resistant and corrosion-resistant materials, with its bottom constructed as a flat wiping surface to provide uniform pressure and wiping effect.

[0036] The moving module 22 is connected to the wiping head 21 and configured to drive the wiping head 21 to move vertically between a wiping position and a clearance position. The wiping position is the working state during cleaning; when the wiping head 21 is in this position, it is in close contact with the liquid inlet. The clearance position is the working position where the wiping head 21 is raised and removed after cleaning. The moving module 22 gives the wiping head 21 the ability to dynamically clear obstacles, allowing it to move vertically. When the wiping element needs to be replaced, the wiping head 21 can be raised to the clearance position, thus creating space for the smooth, low-resistance passage of the wiping element.

[0037] The unwinding assembly 3 and the rewinding assembly 4 together constitute an automated supply and retrieval system for the wiping materials. The unwinding assembly 3 is responsible for storing and conveying clean wiping materials to the working surface of the wiping head 21, while the rewinding assembly 4 is responsible for retrieving used, contaminated wiping materials from the wiping head 21. The coordinated operation of the unwinding assembly 3 and the rewinding assembly 4 enables continuous automated replenishment of the wiping materials, ensuring that clean wiping material is used for each wiping operation, thereby guaranteeing the reliability and consistency of the cleaning effect.

[0038] Optionally, the unwinding assembly 3 and the winding assembly 4 can employ various methods to ensure smooth and controllable conveying of the wiping components. For example, the unwinding assembly 3 can be a passive unwinding mechanism, which can be a freely rotatable unwinding shaft equipped with a friction damper to provide appropriate reverse resistance, thereby preventing the wiping components from excessively loosening due to inertia and maintaining the strip tension. The winding assembly 4 can be an active winding mechanism, which can be a winding shaft driven by a power source to facilitate precise control of the winding length and speed.

[0039] Furthermore, the unwinding assembly 3 can also be an active unwinding mechanism, and the unwinding assembly 3 can be an unwinding shaft driven by a power source. Simultaneously, the winding assembly 4 can be an active winding mechanism, and the winding assembly 4 can be a winding shaft driven by a power source. When replacing the wiping component, the unwinding speed of the unwinding assembly 3 can be controlled to be the same as the winding speed of the winding assembly 4.

[0040] Alternatively, the wiping element can be a disposable, flexible absorbent material. For example, the wiping element can be non-woven fabric, special wiping paper, or other porous fiber products with good liquid retention and softness. These materials can effectively absorb contaminants such as electrolytes, and their softness will not scratch the surface of the injection port, making them suitable for frequent replacement in automated production.

[0041] After a wiping operation is completed, the moving module 22 first drives the wiping head 21 from the wiping position to the clearance position, thereby separating the wiping head 21 from the battery filling port and also disengaging it from the taut wiping piece. Subsequently, the winding assembly 4 activates, pulling the used wiping piece along. Since the wiping head 21 is now in the clearance position, there is no vertical pressure on the wiping piece as it moves below the wiping head 21, thus avoiding forced sliding friction between the wiping head 21 and the wiping piece. The unwinding assembly 3 and the winding assembly 4 respond synchronously, releasing a new clean wiping section and delivering it below the wiping head 21. After the wiping piece has been replaced, the moving module 22 then drives the wiping head 21 down to the wiping position, ready for the next cleaning operation.

[0042] Thus, the wiping mechanism 100 provided in this embodiment solves the problem of wear on the wiping head 21 caused by friction between the nonwoven fabric and the fixed wiping head 21 during non-wiping phases in the prior art. The wiping mechanism 100, controlled by the moving module 22, allows the wiping head 21 to actively avoid contact during non-wiping phases, ensuring that the replacement of the wiping component is completed without or with low interference. This extends the service life of the wiping head 21 and reduces maintenance costs and downtime caused by frequent replacements. Furthermore, by avoiding friction between the wiping head 21 and the wiping component, it indirectly prevents secondary contamination of the battery filling port by particles or fiber debris that may be generated due to wear of the wiping head 21 or the wiping component, further improving the reliability of the cleaning process.

[0043] Please see Figure 2 and Figure 6 In some embodiments, the moving module 22 includes a fixing member 221, which is disposed on the bracket 1; the wiping assembly 2 also includes a carrier member 23, which is disposed on the fixing member 221. The carrier member 23 is configured to carry the wiping member. The wiping member is conveyed to the carrier member 23 by the unwinding assembly 3 and then received by the winding assembly 4. The carrier member 23 is used to limit the distance between the wiping member and the fixing member 221 so that the wiping head 21 can be separated from the wiping member when it is in the avoidance position.

[0044] The fastener 221 is fixedly mounted on the bracket 1, providing a mounting base and load-bearing frame for the moving module 22. The fastener 221 avoids the cumulative assembly errors and structural deformation that may occur due to the connection of multiple components to the bracket 1, ensuring the reliability of the reference of the moving module 22 during long-term repetitive motion.

[0045] In one possible embodiment, the number of carriers 23 can be one, and the position layout of the unwinding assembly 3 or the winding assembly 4 can be adjusted accordingly. Specifically, the structural size of the unwinding assembly 3 can be designed to be larger, or the installation position of the unwinding assembly 3 can be appropriately lowered and offset to one side, so that the output end of the unwinding assembly 3 can form a complete wiping component transmission path together with the single carrier 23 set on the other side.

[0046] In this configuration, a clearance space is naturally formed between the output end of the unwinding assembly 3 and the carrier 23 on the other side. This clearance space provides sufficient range of motion for the lifting and lowering movement of the wiping head 21 so that the wiping head 21 can be separated from the wiping component when it is in the clearance position. At the same time, the output end of the unwinding assembly 3 itself plays a guiding and supporting role equivalent to the carrier on the other side.

[0047] In another embodiment, a separate support member 23 may not be required. The transmission and support of the wiping component can be achieved by arranging the positions of the unwinding assembly 3 and the winding assembly 4. Specifically, the unwinding assembly 3 and the winding assembly 4 are respectively arranged on one side and the other side of the wiping head 21, and the height and position of the output end and the input end are adjusted.

[0048] In this configuration, the output of the unwinding assembly 3 directly functions as one of the carriers 23, conveying the wiping material to the wiping head 21 area. The input of the rewinding assembly 4 directly functions as the other carrier 23, receiving the wiping material from the wiping head 21 area. The unwinding assembly 3 and the rewinding assembly 4 together replace the functions of the two independent carriers 23, forming a complete transmission path from unwinding to rewinding.

[0049] In another embodiment, there can be two carriers 23, both of which are disposed on the fixing member 221 and located on opposite sides of the wiping head 21. The carriers 23 serve as key fulcrums on the wiping component's transmission path, providing stable and symmetrical tension support. As the wiping component crosses between the two carriers 23, it forms a stable and flat working section that covers the bottom working surface of the wiping head 21, preventing loosening, wrinkling, or lateral shifting of the wiping component during transmission and use, thereby ensuring the uniformity and consistency of the contact area between the wiping head 21 and the battery filling port.

[0050] Both the unwinding assembly 3 and the rewinding assembly 4 are positioned above the wiping assembly 2. The wiping component is conveyed by the unwinding assembly 3 to one of the carriers 23, then passes through the working area of ​​the wiping head 21, and finally is guided by the other carrier 23 to the rewinding assembly 4 for reception. This high-level arrangement and specific path planning optimize the spatial layout of the wiping component. Concentrating the rewinding and unwinding functional modules above the wiping assembly 2 facilitates the integration of the drive source and control system, reduces the horizontal space occupied by the wiping mechanism 100, and makes the overall structure of the wiping mechanism 100 more compact.

[0051] Please see Figure 2 and Figure 6 In some embodiments, the height of the two carriers 23 is higher than the height of the wiping head 21 when it is in the wiping position, and the height of the two carriers 23 is lower than the height of the wiping head 21 when it is in the avoidance position.

[0052] When the wiping head 21 moves to the lower wiping position under the drive of the moving module 22 to perform the cleaning operation, since the actual height of the wiping head 21 is lower than the support members 23 on both sides, the wiping component forms a natural recessed area when it crosses the two support members 23 and passes the bottom of the wiping head 21. During the process of the wiping head 21 pushing the wiping component downward, a stable and appropriate tension is established inside the wiping component, ensuring that the wiping component can be flat and tightly attached to the working surface of the wiping head 21, avoiding wrinkles caused by material looseness, thus providing uniform and reliable contact for the cleaning operation, and ensuring the uniformity and thoroughness of the cleaning effect.

[0053] When the cleaning operation is completed, the moving module 22 drives the wiping head 21 to rise to the clearance position, at which point the height of the wiping head 21 will exceed the height of the two supporting members 23. At this time, the tension area of ​​the wiping component, which was originally pressed downward by the wiping head 21, is released, and the wiping component returns to a relatively relaxed state between the two supporting members 23 and separates from the wiping head 21. The height of the two supporting members 23 is lower than the height of the wiping component when it is in the clearance position, ensuring that the wiping component can be supported by the supporting members 23 when it moves upward to the clearance position. This prevents the wiping component from retracting during winding and causing it to come into contact with the wiping head 21, thereby further avoiding friction between the wiping component and the wiping head 21.

[0054] Please see Figure 2 and Figure 6 In some embodiments, the carrier 23 includes a roller configured to contact the wiping element. When the wiping element moves, the roller rotates under the influence of the wiping element. The contact between the roller and the wiping element, and its rotation during movement, reduces the resistance experienced by the wiping element during transport. When the winding assembly 4 pulls the wiping element for replacement, the relative motion between the wiping element and the carrier 23 is primarily converted into the rotation of the roller itself, thus avoiding potential sliding friction between the wiping element and the surface of the fixed carrier 23. This low-resistance operating mode makes the movement of the wiping element smoother and easier to control, reduces the traction force required by the winding assembly 4, helps reduce the load and energy consumption of the winding drive components, and improves the reliability and stability of the wiping element replacement operation.

[0055] Please see Figure 3 In some embodiments, the moving module 22 further includes: a first guide member 222, which is disposed on the fixing member 221; and a lifting drive member 223, the driving end of the lifting drive member 223 passing through the first guide member 222, and the driving end of the lifting drive member 223 being connected to the wiping head 21 to drive the wiping head 21 to move between the wiping position and the avoidance position.

[0056] The first guide member 222 is disposed on the fixed member 221, and the driving end of the lifting drive member 223 passes through the first guide member 222. The first guide member 222 constrains and guides the driving end of the lifting drive member 223, ensuring that the movement trajectory of the driving end is restricted to the expected vertical direction. This guiding effect can overcome the slight radial gap or sway tendency that may exist in the lifting drive member 223 itself, and prevent the wiping head 21 from unexpected horizontal deviation or torsion during the lifting process, so that the wiping head 21 can accurately descend from the avoidance position to the same wiping position every time, thereby ensuring the consistency and reliability of the cleaning effect.

[0057] Please see Figure 4 , Figure 4 for Figure 3 A partial enlarged view at point A. In some embodiments, the first guide member 222 has a connecting hole that extends vertically through the first guide member 222. The driving end of the lifting drive member 223 is connected to the wiping head 21 located below the first guide member 222 through the connecting hole. The moving module 22 also includes a support member 224 that extends vertically. The first end of the support member 224 is connected to the upper surface of the first guide member 222, and the second end of the support member 224 is connected to the non-driving end of the lifting drive member 223, so that the lifting drive member 223 is suspended.

[0058] The first guide member 222 has a connecting hole that extends vertically through it. The driving end of the lifting drive member 223 passes through this connecting hole and connects to the wiping head 21 located below the first guide member 222. This allows the first guide member 222 to not only serve as a guide but also as a physical isolation and limiting component for the movement path of the drive end. The connecting hole provides a channel for the vertical movement of the drive end and constrains its degree of freedom in the horizontal direction.

[0059] The moving module 22 also includes a support member 224, which extends vertically. The first end of the support member 224 is connected to the upper surface of the first guide member 222, and the second end is connected to the non-driving end of the lifting drive member 223, thus suspending the lifting drive member 223 in a suspended state. The support member 224 transmits the weight of the lifting drive member 223 and its reaction force during operation to the first guide member 222, which is ultimately borne by the fixing member 221 and the bracket 1, forming a clear path and a highly rigid frame system.

[0060] The suspended design of the lifting drive component 223 avoids interference between the lifting drive component 223 and the movement space of the wiping head 21 below, freeing up more space for the lifting stroke of the wiping head 21 and the layout of surrounding components, thus enhancing the compactness and flexibility of the wiping mechanism 100. At the same time, this suspended installation method also facilitates the maintenance and replacement of the lifting drive component 223 without disassembling the entire moving module 22 or the wiping head 21 assembly below.

[0061] Please see Figure 5 , Figure 5 This is a second schematic diagram of the structure of the wiping assembly 2 provided in an embodiment of this application. In some embodiments, the moving module 22 further includes: a connecting shaft 225, the first end of which is connected to the driving end of the lifting drive member 223, and the second end of which is connected to the wiping member; and a floating joint 226, which is movably disposed relative to the first guide member 222, and the connecting shaft 225 is connected to the driving end through the floating joint 226.

[0062] The floating joint 226 is movably configured relative to the first guide member 222, and the connecting shaft 225 is connected to the drive end via the floating joint 226. In actual assembly and operation, there may be slight alignment errors between the centerline of the drive end of the lifting drive member 223, the centerline of the connecting shaft 225, and the centerline of the connecting hole of the first guide member 222. The floating joint 226 can automatically compensate for these slight radial, angular, or axial deviations, avoiding the formation of an over-positioned statically unstable structure. This compensation reduces the risk of hard friction or jamming between the connecting shaft 225 and the inner wall of the connecting hole of the first guide member 222, and also reduces the additional radial load borne by the output shaft of the lifting drive member 223.

[0063] Optionally, the structure of the floating joint 226 can have various specific implementations to achieve automatic compensation for minor deviations. For example, the floating joint 226 can be a ball joint structure, in which the ball head and the socket cooperate to enable the connecting shaft 225 to achieve multi-degree-of-freedom deflection within a certain conical angle range, thereby compensating for the angular deviation between the drive end and the connecting shaft 225.

[0064] Alternatively, the floating joint 226 can also be a universal joint structure, connected by a cross shaft or hinge mechanism, allowing the connected components to produce relative angular displacement in two mutually perpendicular directions, suitable for applications requiring compensation for large angular deviations.

[0065] Optionally, the floating joint 226 may also adopt an elastic element structure, such as a rubber ring, polyurethane elastomer or diaphragm inside the joint, which uses the deformation of the elastic material to absorb the combined deviations of radial, angular and axial directions, and at the same time can play a role in buffering and vibration reduction. The structure of the floating joint 226 is not limited in the embodiments of this application.

[0066] Please see Figure 4 In some embodiments, the first guide member 222 has a floating groove 2221 that communicates with a connecting hole, and a floating joint 226 is floatingly disposed in the floating groove 2221. The floating groove 2221 extends along a first direction that is perpendicular to the vertical direction.

[0067] The first guide member 222 has a floating groove 2221 that communicates with the connecting hole. The floating joint 226 is floatingly disposed within the floating groove 2221, and the floating groove 2221 extends along a first direction, providing a controlled and directional floating space for the floating joint 226. The floating groove 2221 allows the floating joint 226 to no longer be completely rigidly constrained around the connecting hole, but to perform limited and controllable translational movements in a specific horizontal direction, i.e., the first direction.

[0068] The floating joint 226 is floatingly disposed within the floating groove 2221, which directionally guides and precisely limits the compensation capability of the floating joint 226. The floating groove 2221 allows the floating joint 226 to adaptively adjust its position in a first direction perpendicular to the vertical direction, thereby effectively absorbing and compensating for any alignment errors that may exist between the center line of the driving end of the lifting drive member 223 and the center line of the connecting hole of the first guide member 222 in the first direction. This directional floating mechanism avoids releasing other unnecessary degrees of freedom, ensuring that the vertical movement accuracy of the wiping head 21 is not affected, while eliminating assembly stress and movement interference in specific directions.

[0069] Please see Figure 3 In some embodiments, the moving module 22 further includes: a mounting member 227, which includes a first mounting part and a second mounting part connected to each other, the first mounting part being connected to the bracket 1, the second mounting part being connected to the first guide member 222, and the second mounting part being located below the first guide member 222; and a second guide member 228, which is connected to the second mounting part and is located below the second mounting part, and the driving end of the lifting drive member 223 passes through the second guide member 228 to connect with the wiping head 21 located below the second guide member 228.

[0070] The moving module 22 also includes a mounting member 227, which comprises a first mounting portion and a second mounting portion connected to each other. The first mounting portion is connected to the bracket 1, thus fixing the moving module 22 on the bracket 1. The second mounting portion is connected to the first guide member 222 and is located below the first guide member 222, forming a stable support frame. The location of the second mounting portion below the first guide member 222 allows the first guide member 222 to receive support from below, enhancing the rigidity of the first guide member 222 when subjected to the reaction force from the wiping head 21 and suppressing the deformation tendency of the first guide member 222.

[0071] The moving module 22 also includes a second guide 228, which is connected to the second mounting portion and located below it. The driving end of the lifting drive 223 passes sequentially through the connecting hole of the first guide 222 and the second guide 228, and finally connects to the wiping head 21 located below the second guide 228. The second guide 228 and the first guide 222 together constitute a multi-stage guiding system. The first guide 222 is located at the upper part of the movement stroke, and the second guide 228 is located at the lower part of the movement stroke and closer to the wiping head 21. This arrangement provides two-point guidance for the driving end of the lifting drive 223. The second guide 228 can provide additional supporting torque to ensure that the driving end always maintains a precise vertical movement trajectory.

[0072] Please see Figure 1and Figure 2 In some embodiments, the wiping mechanism 100 further includes a rotary drive 5, which is connected to the bracket 1 and is configured to drive the bracket 1 to rotate about the drive axis of the rotary drive 5.

[0073] The rotary drive unit 5 provides a rotary wiping function for the wiping operation. When the wiping head 21 is in the wiping position and contacts the battery filling port, the rotary drive unit 5 drives the entire bracket 1 and other components on the bracket 1 to rotate around the vertical drive axis. This rotational motion causes the wiping head 21 to generate circumferential friction relative to the filling port, achieving annular cleaning of the filling port end face and surrounding area. Rotary wiping can more effectively break down and remove dried or viscous electrolyte residues, improving the thoroughness and efficiency of cleaning.

[0074] The rotational motion is applied to the entire support 1 and the components mounted on it. The unwinding component 3 and the winding component 4 rotate together with the support 1, ensuring that the non-woven fabric segment on the wiping head 21 remains relatively stationary during the rotational wiping process. This avoids accidental friction or wrinkles caused by the relative movement of the two, and ensures the uniform distribution of wiping pressure and the stability of the cleaning action.

[0075] Please see Figure 3 In some embodiments, the fixing member 221 has a mounting hole, and the first guide member 222 is disposed within the mounting hole. A rotary bearing 6 is provided between the first guide member 222 and the mounting hole to allow the first guide member 222 to rotate relative to the mounting hole. The rotary bearing 6 enables the first guide member 222 to rotate smoothly and with low resistance relative to the mounting hole of the fixing member 221, thus integrating the lifting and guiding functions and the rotation function of the moving module 22. The first guide member 222 is firmly supported on the fixing member 221 through the mounting hole and the rotary bearing 6, ensuring the rigidity and stability of the first guide member 222 as a guiding component in the vertical direction, and ensuring the lifting and lowering trajectory of the wiping head 21. At the same time, the rotary bearing 6 allows the first guide member 222 and its connected components, such as the wiping head 21, to rotate freely about their own axis in the horizontal plane.

[0076] Please see Figure 5 and Figure 6 , Figure 6 This is a third schematic diagram of the structure of the wiping assembly 2 provided in the embodiments of this application. In some embodiments, the wiping mechanism 100 further includes: a liquid receiving tank 7, which is connected to the wiping head 21; and a liquid injection component 8, which is disposed on the wiping assembly 2 and configured to deliver cleaning liquid to the liquid receiving tank 7.

[0077] The connection between the receiving tank 7 and the wiping head 21 provides a dedicated container for the temporary storage and guidance of the cleaning fluid. The receiving tank 7 receives and temporarily holds the cleaning fluid from the filling port 8, and then, through its connection with the wiping head 21, allows the cleaning fluid to slowly and controllably permeate into the working area at the bottom of the wiping head 21. This process prevents the cleaning fluid from flowing haphazardly or splashing across the surface of the wiping head 21, ensuring that the cleaning fluid is concentrated and efficiently applied to the surface of the battery filling port that needs cleaning, while preventing potential contamination or corrosion of other non-target areas.

[0078] The liquid injection unit 8 is located on the wiping assembly 2 and is configured to deliver cleaning fluid to the receiving tank 7, achieving automatic and precise supply of cleaning fluid. The liquid injection unit 8 can be a precision valve or metering pump connected to an external liquid supply system, capable of injecting specific types of cleaning fluid, such as volatile solvents or specialized cleaning agents, into the receiving tank 7 at regular intervals and in precise quantities according to the needs of the cleaning process, thus achieving chemical assistance and automated integration of the cleaning process. By precisely controlling the supply of cleaning fluid, it ensures that sufficient cleaning fluid is available to dissolve and dilute stubborn electrolyte crystals, while preventing excessive liquid overflow that could lead to contamination of the battery surface or the inside of the equipment, thereby improving the precision and controllability of the cleaning process.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
