Description

Technical Field

[0001] This utility model relates to the technical field of lithium-ion battery manufacturing equipment, and in particular to a battery filling port cleaning device. Background Technology

[0002] In the manufacturing process of lithium-ion batteries, electrolyte injection (referred to as "electrolyte injection") is a crucial step. The quality of electrolyte injection directly affects the battery's electrochemical performance, safety performance, and lifespan. However, in actual production, a small amount of electrolyte often remains in the injection port area after injection. Because electrolyte is highly corrosive, its residue on the battery casing surface can cause corrosion damage to the casing material, especially aluminum casings or aluminum-plastic films. In severe cases, it can even lead to casing perforation and seal failure, resulting in safety hazards such as leakage, short circuits, and bulging. Furthermore, residual electrolyte can interfere with subsequent soldering processes, affecting solder joint quality and sealing effectiveness, reducing battery consistency and yield.

[0003] Therefore, the cleaning process after battery electrolyte filling is particularly important. Currently, the industry commonly uses manual wiping, where workers use non-woven fabrics or other absorbent materials to clean the area around the filling port to remove electrolyte residue. While this method has low technical barriers and requires little equipment investment, it is inefficient and has several significant drawbacks: First, the manual operation is arduous and unsuitable for the pace of large-scale, continuous production lines, and the cleaning quality is greatly affected by the operator's skill level, resulting in poor stability; second, electrolytes are volatile and somewhat toxic, and prolonged manual contact can easily cause health damage to operators, which is detrimental to safe production management; third, the repetitive nature of manual labor is difficult to standardize and digitize, which is inconsistent with the current trend of intelligent upgrading in manufacturing.

[0004] To address the aforementioned technical issues, existing technologies have introduced an automatic wiping device. While this solves the problem of high manual labor intensity and unsuitability for large-scale, continuous production, most commercially available automatic wiping devices currently use threaded connections or other structures such as snap-fit ​​or plug-in connections between the rotating head and its base. Although these structures can meet some replacement needs, they generally suffer from cumbersome replacement procedures, difficult alignment, and long processing times. This hinders rapid model switching on the production line, impacting overall production cycle time and operational efficiency.

[0005] Therefore, how to achieve efficient, stable, and automated cleaning of residual electrolyte at the injection port, while optimizing the wiping head structure, simplifying the replacement process, and shortening the changeover time, has become an urgent technical challenge.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0035] like Figures 1 to 3 As shown, in order to achieve the above objectives, this utility model proposes a battery filler neck cleaning device, comprising:

[0036] Rotating component 10;

[0037] The first telescopic member 11 is connected to the rotating member 10 and can rotate with the rotating member 10;

[0038] The fixing member 12 has a mounting groove for installing a wiping component, and the fixing member 12 is connected to the first telescopic member 11; and

[0039] The wiping assembly 13 is snapped into the mounting groove. The first telescopic member 11 drives the fixing member 12 to move closer to or away from the battery filling port, so that the wiping assembly 13 wipes the battery filling port.

[0040] Specifically, the rotating component 10 is an electric rotary table or a rotating shaft structure equipped with a motor drive structure, and its output end is fixedly connected to a first telescopic component 11. The rotating component 10 is mounted on the base structure of the device and can rotate around a set angle.

[0041] The first telescopic member 11 is an electric push rod or pneumatic cylinder structure, with one end fixedly connected to the rotating member 10 and the other end fixedly connected to the fixing member 12. The first telescopic member 11 is used to control the extension or retraction of the fixing member 12 in the vertical direction to achieve the approach or distance from the battery filling port, thereby controlling the contact state between the wiping assembly 13 and the battery filling port.

[0042] The fixing member 12 is a shell structure or frame component, which has a mounting groove for installing the wiping assembly 13. The groove opening is provided with positioning protrusions or snap-fit ​​components to facilitate the insertion and positioning of the wiping assembly 13 on the fixing member 12, preventing it from shaking or falling off during operation.

[0043] The wiping assembly 13 includes a housing, an insertion head 131, and an electrolyte wiping cloth 40 for cleaning, which is wrapped around the outer surface of the wiping assembly 13. The insertion head 131 is provided with a snap-fit ​​structure for engaging with the mounting groove of the fixing member 12, thereby stably mounting the wiping assembly 13 on the fixing member 12.

[0044] During use, the operator or control system first controls the first telescopic member 11 to extend, causing the fixing member 12 and its wiping assembly 13 to move towards the battery filling port until the electrolyte wiping cloth 40 of the wiping assembly 13 contacts the surface of the filling port. Then, the rotating member 10 drives the wiping assembly 13 to rotate, thereby effectively wiping away electrolyte residue or stains from the surface of the filling port. After wiping, the first telescopic member 11 is retracted, moving the fixing member 12 and the wiping assembly 13 away from the filling port.

[0045] To facilitate the replacement of the wiping component 13, the mounting slot is designed as a quick-plug structure. When the wiping cloth 40 is heavily soiled or reaches its replacement cycle, the operator can directly remove the original wiping component 13 and insert the new wiping component 13 into the mounting slot without tools, making the operation simple.

[0046] By adopting the above technical solution, the battery filling port cleaning device of this utility model realizes the contact control between the wiping component 13 and the battery filling port through the first telescopic component 11, ensuring the accuracy and flexibility of the wiping action; at the same time, the wiping component 13 adopts a detachable design, which is convenient for maintenance and replacement, greatly improving the cleaning efficiency and automation level, and reducing the burden of manual operation.

[0047] In one embodiment of this application, a first through hole 122 and a second through hole 123 are provided on one side of the mounting groove. The first through hole 122 and the second through hole 123 are coaxially arranged and communicate with each other. One end of the first through hole 122 communicates with the outside of the mounting groove, and one end of the second through hole 123 communicates with the inside of the mounting groove. The diameter of the first through hole 122 is smaller than the diameter of the second through hole 123.

[0048] A pull rod 124 is provided in the first through hole 122 and the second through hole 123. A pull plate 125 is provided at the end of the pull rod 124 away from the mounting groove. A three-sided sliding panel 126 is provided at the end of the pull rod 124 near the mounting groove. A compression spring is sleeved on the pull rod 124. The first end of the spring abuts against the connection between the first through hole 122 and the second through hole 123, and the second end of the spring abuts against the three-sided sliding panel 126.

[0049] Specifically, a mounting groove is provided on one side of the fastener 12, and a first through hole 122 and a second through hole 123 are sequentially formed on the mounting groove. The first through hole 122 and the second through hole 123 are arranged along the same axis and are connected to each other. One end of the first through hole 122 is connected to the external space of the mounting groove for inserting and pulling the limiting structure, and one end of the second through hole 123 is connected to the internal space of the mounting groove for limiting the insertion head 131 of the wiping assembly 13. To achieve a guiding transition during the limiting assembly process, the diameter of the first through hole 122 is smaller than the diameter of the second through hole 123, thereby forming an inner shoulder surface at the abrupt change in diameter for supporting the spring compression.

[0050] A limiting pull rod 124 is slidably installed within the channels of the first through hole 122 and the second through hole 123. The pull rod 124 passes through both through holes and has two end components: a limiting pull plate 125 is provided at the end near the outside of the mounting groove for manual operation by the user to pull out or release the limiting device; a three-sided sliding panel 126 is provided at the end near the inside of the mounting groove, and the three limiting surfaces of the three-sided sliding panel 126 respectively form sliding or contact engagement with the inside of the mounting groove, the insertion head 131 of the wiping assembly 13, and the inner wall of the second through hole 123, thereby achieving lateral limiting of the insertion head 131 of the wiping assembly 13.

[0051] To achieve the automatic reset function, a compression spring is also sleeved on the outside of the limiting pull rod 124. The first end of the compression spring abuts against the stepped surface (inner shoulder surface) formed at the connection position of the first through hole 122 and the second through hole 123, and the second end abuts against the back of the three-sided sliding panel 126. When the user pulls the limiting pull plate 125, the compression spring is compressed, and the three-sided sliding panel 126 moves outward with the limiting pull rod 124, thereby releasing the limitation on the insertion head 131 of the wiping assembly 13. After the wiping assembly 13 is replaced and inserted into place, the user releases the spring, and the compression spring releases its elastic force to push the three-sided sliding panel 126 to automatically reset, thereby locking the wiping assembly 13 again.

[0052] By adopting the above technical solution, a first through hole 122 and a second through hole 123 are provided on the fixing component 12 for coaxial conduction, and a pull rod 124, a pull plate 125, a three-sided sliding panel 126 and a compression spring are provided inside them. This allows the user to release the limiting pull plate 125 to release the limiting of the wiping component 13, realizing the quick disassembly and replacement of the wiping component 13. After release, it will automatically reset under the action of the compression spring and re-limit the wiping component 13. This significantly improves the convenience and stability of the installation of the wiping component 13, ensures that the wiping head will not fall off during high-speed operation of the device, and effectively enhances the safety, reliability and practicality of the device.

[0053] In one embodiment of this application, the wiping assembly 13 includes:

[0054] Insertion head 131 can be inserted into the mounting slot. The insertion head 131 is provided with a blind hole that cooperates with the three-sided sliding panel 126 to lock the insertion head 131.

[0055] A rotating wiping head 132 is connected to the insertion head 131, and the rotating wiping head 132 can cover the wiping cloth 40; and

[0056] A clamping cap 133 is fitted onto the rotating wiping head 132. The clamping cap 133 has a threaded hole, and a threaded rotating rod 134 that mates with the threaded hole is provided in the threaded hole. One end of the threaded rotating rod 134 near the rotating plug has a pressing plate 136 that can press the wiping cloth 40 against the rotating wiping head 132. The pressing plate 136 and the threaded rotating rod 134 are connected by a bearing.

[0057] Specifically, the insertion head 131 is a columnar structure, and its outer diameter matches the internal dimensions of the mounting groove, allowing for plug-in and pull-out installation. The outer wall of the insertion head 131 has at least one blind hole, the position and size of which correspond to the limiting protrusion of the three-sided sliding panel 126. When the wiping assembly 13 is inserted into the mounting groove, the three-sided sliding panel 126 resets under the action of a compression spring and engages with the blind hole on the insertion head 131, thereby locking and positioning the insertion head 131 and preventing axial or rotational sliding during wiping.

[0058] The rotating wiping head 132 is located at the bottom of the insertion head 131. It has a cylindrical disk structure and can rotate around its own central axis. The rotation is driven by the rotating component 10. The outer wall of the rotating wiping head 132 is an annular friction surface, which is used to cover the electrolyte wiping cloth 40. The wiping cloth 40 covers its outer surface to achieve the cleaning function of the battery filling port.

[0059] To ensure that the wiping cloth 40 does not loosen or fall off during high-speed rotation, the wiping assembly 13 also includes a clamping cap 133. The clamping cap 133 is a sleeve-shaped structure that is fitted onto the outside of the rotating wiping head 132, and its outer shell has a threaded hole. A threaded rotating rod 134 is installed in the threaded hole.

[0060] The threaded rotating rod 134 is a one-end driven structure. Its end near the rotating wiping head 132 is connected to the pressing plate 136 via a bearing, allowing the pressing plate 136 to advance or retract axially when the threaded rotating rod 134 is rotated. The pressing plate 136 is arc-shaped or panel-shaped, with its pressing surface in contact with the outer surface of the wiping cloth 40 between the rotating wiping heads 132. By rotating the threaded rotating rod 134, the pressing plate 136 can be controlled to press or release the wiping cloth 40, enabling quick replacement, secure positioning, and uniform pressure on the wiping cloth 40. The bearing ensures that the pressing plate 136 can move with the threaded rotating rod 134 but will not rotate with it, thus avoiding the risk of entanglement or damage to the wiping cloth 40.

[0061] The wiping assembly 13 can be quickly inserted into the mounting slot and automatically locked by the three-sided sliding panel 126 and the blind hole limit. At the same time, it is convenient for maintenance personnel to quickly disassemble and fix the wiping cloth 40 by means of the clamping cap 133 mechanism.

[0062] By adopting the above technical solution, by setting a blind hole structure on the insertion head 131 that cooperates with the three-sided sliding panel 126, the wiping assembly 13 can be automatically limited and locked after being inserted into the mounting slot, preventing it from loosening; the rotating wiping head 132 provides effective wiping power; and the design of the clamping cap 133, together with the threaded rotating rod 134 and the squeezing plate 136, can efficiently press the wiping cloth 40 onto the surface of the rotating wiping head 132, and can realize the quick replacement of the wiping cloth 40. The operation is convenient and the positioning is stable, which effectively improves the structural reliability and service life of the device under high-frequency use.

[0063] In one embodiment of this application, a turntable 135 is provided at the end of the threaded rod 134 away from the rotary plug.

[0064] Specifically, the turntable 135 is a circular, flat disc with its central shaft hole coaxial with the axis of the threaded rotating rod 134, and is fixedly installed at the end of the threaded rotating rod 134. The diameter of the turntable 135 is larger than the diameter of the threaded rotating rod 134, and its outer edge is provided with anti-slip texture or raised dots to facilitate manual rotation. The turntable 135 engages with the threaded hole on the pressure cap 133 through the threaded rotating rod 134, allowing the user to rotate the threaded rotating rod 134 by rotating the turntable 135.

[0065] When the user needs to replace the electrolyte wiping cloth 40, simply rotate the turntable 135 to drive the threaded rod 134 outward in the threaded hole of the clamping cap 133, thereby causing the pressure plate 136 to retract and release the wiping cloth 40. After replacing the wiping cloth 40, rotate the turntable 135 again to push the threaded rod 134 inward, causing the pressure plate 136 to press the wiping cloth 40 and fix it to the outer surface of the rotating wiping head 132, achieving an efficient and tool-free fastening operation.

[0066] The turntable 135 in this structure can be injection molded from metal or engineering plastic, offering high strength and wear resistance to meet the requirements of frequent operation in industrial settings. Furthermore, because it is located externally to the device, operators can directly and manually adjust the turntable 135 without touching the threaded rod body, improving operational convenience and safety.

[0067] By adopting the above technical solution, a turntable 135 is provided at the end of the threaded rotating rod 134 away from the rotating wiping head 132. This allows the user to quickly adjust the position of the pressing plate 136 simply by rotating the turntable 135 without the aid of any tools, thereby achieving efficient pressing or releasing of the wiping cloth 40. This structure simplifies the operation process of replacing the wiping cloth 40 and improves the efficiency and comfort of the equipment.

[0068] In one embodiment of this application, the extrusion plate 136 is provided with a guide slider 137.

[0069] Specifically, the guide slider 137 is a sliding fit structural element, fixedly installed on the upper surface or both sides of the extrusion plate 136. The outer surface of the guide slider 137 forms a sliding fit with the inner wall of the clamping cap 133 or the auxiliary structure. The guide slider 137 can be made of a low coefficient of friction material, such as polytetrafluoroethylene, nylon, or a metal slider coating, which ensures smooth sliding and improves wear resistance.

[0070] As the threaded rotating rod 134 drives the extrusion plate 136 to move axially, the guide slider 137 always adheres to and slides within the guide rail surface or limiting groove surface inside the clamping cap 133. This restricts the extrusion plate 136 to move only along the axial direction of the threaded rotating rod 134, preventing unstable movements such as tilting or swaying on the surface of the rotating wiping head 132. This guiding structure further improves the uniformity of the extrusion effect, allowing the electrolyte wiping cloth 40 to stably and uniformly adhere to the outer surface of the rotating wiping head 132, ensuring consistent and reliable wiping results.

[0071] Each extrusion plate 136 may be equipped with one or more guide sliders 137, which may be symmetrically arranged according to structural requirements to maintain force balance during the pressing process. The guide sliders 137 and the pressing caps 133 may be fitted together by limiting grooves or guide slots to form sliding constraints.

[0072] By adopting the above technical solution, and by setting a guide slider 137 on the extrusion plate 136, the movement direction of the extrusion plate 136 can be effectively restricted, ensuring that it slides smoothly along the axis of the threaded rotating rod 134, avoiding skewing or shaking during movement, thereby improving the uniformity of pressing and the firmness of the electrolyte wiping cloth 40. This structure improves the overall wiping stability of the device and reduces the risk of the wiping cloth 40 becoming loose.

[0073] In one embodiment of this application, it further includes:

[0074] The second telescopic member 20 is connected to the rotating member 10 and is used to drive the rotating member 10 to move in the horizontal direction.

[0075] Specifically, the second telescopic member 20 is preferably an electric push rod, a lead screw slide, or a pneumatic cylinder structure, with one end fixedly installed on the device base plate or base structure, and the other end fixedly connected to the rotating member 10. The second telescopic member 20 is arranged along the horizontal axis, and its working axis is perpendicular to the movement direction of the first telescopic member 11, thereby forming a three-dimensional adjustable structure, which facilitates the adjustment of the position of the wiping assembly 13 on the horizontal plane.

[0076] When the second telescopic component 20 is activated, its extension or retraction will cause the rotating component 10 to move horizontally on the base plate. Through precise control of the second telescopic component 20, the wiping assembly 13 can be precisely aligned between multiple different battery filling ports, forming a two-dimensional positioning capability in conjunction with the rotation function of the rotating component 10 itself.

[0077] By adopting the above technical solution, by setting a second telescopic member 20 between the rotating member 10 and the base plate, the rotating member 10 not only has a rotation function, but can also move in the horizontal direction, thereby expanding the wiping range of the entire cleaning device.

[0078] In one embodiment of this application, it further includes:

[0079] The second rotating member 30 is connected to the second telescopic member 20, and the length direction of the second rotating member 30 is parallel to the length direction of the first telescopic member 11.

[0080] Specifically, the second rotating member 30 is a rotary connection structure, with one end connected to the output end of the second telescopic member 20 and the other end connected to the rotating member 10 or the mounting platform supporting the first telescopic member 11, thereby forming a rotatable intermediate connection part. The length direction of the second rotating member 30 is parallel to the length direction of the first telescopic member 11; in other words, their axial directions correspond to each other and are coplanar and parallel.

[0081] By adopting the above technical solution, by setting a second rotating member 30 parallel to the first telescopic member 11 in the length direction, the rotation of the second rotating member 30 can drive the first telescopic member 11 and the second rotating member 30 to rotate, thereby cleaning the battery cells at different positions and greatly improving the cleaning efficiency of different battery cells.

[0082] In one embodiment of this application, it further includes:

[0083] A support platform 50 is provided, and the second rotating component 30 is disposed on the support platform 50. The support platform 50 is provided with an arc-shaped guide rail that can hold multiple wiping components 13. The second rotating component 30 is located at the center of the arc-shaped guide rail.

[0084] Specifically, the support platform 50 is an integral frame structure used to support the installation of the second rotating component 30 and its related parts. The second rotating component 30 is mounted on the center position of the support platform 50 via a mounting base and is perpendicularly connected to the upper surface of the support platform 50.

[0085] One or more arc-shaped guide rails are provided on the upper surface of the support platform 50. The arc-shaped guide rails are distributed in an arc around the central axis of the second rotating member 30. The arc-shaped guide rails are used to place multiple spare wiping components 13. Each wiping component 13 is snapped onto the corresponding position on the guide rail by its insertion head 131 and is kept in the same direction as the tangent of the guide rail to facilitate subsequent picking actions.

[0086] The arc-shaped guide rail may be provided with several evenly distributed positioning slots or grooves to ensure that each wiping component 13 is clearly positioned and securely installed on the guide rail, avoiding slippage or collision during movement. The second rotating component 30 is located at the center of the arc-shaped guide rail, allowing the wiping component 13 it drives to be precisely aligned with any position on the guide rail by rotation, completing the recycling of the old wiping component 13 or the picking up of the new wiping component 13.

[0087] During operation, when the wiping task is completed, the first telescopic component 11 retracts the wiping component 13 to the designated height, and the second rotating component 30 rotates so that it faces the empty space on the arc-shaped guide rail, and the wiping component 13 can be released and fall into the guide rail recycling slot; then it rotates again to the position of the new wiping component 13, the first telescopic component 11 descends, inserts and engages the new wiping component 13, and the automatic replacement is completed.

[0088] By adopting the above technical solution, and by setting an arc-shaped guide rail on the support platform 50 and positioning the second rotating component 30 at the center of the arc-shaped guide rail, the orderly storage and precise switching of multiple wiping components 13 are achieved. This structure allows the replacement process of the wiping components 13 to be completed automatically by the device itself without manual intervention, greatly improving the continuity and efficiency of cleaning tasks. At the same time, it avoids misalignment and jamming problems during frequent replacements, and enhances the automation level and adaptability of the entire machine.

[0089] In one embodiment of this application, a collection groove 60 for collecting waste wiping components 13 is provided on one side of the support platform 50.

[0090] Specifically, the collection tank 60 is an upward-facing accommodating structure, with its opening edge located in the edge region of the support platform 50, and is fixedly connected to the support platform 50 by screws, welding, or snap-fit ​​structures. The accommodating space of the collection tank 60 is adapted to the external dimensions of the wiping assembly 13, and can receive multiple used wiping assemblies 13, maintaining their stable stacking state within the tank.

[0091] After the wiping task is completed, the first telescopic component 11 drives the fixing component 12 to lift the wiping assembly 13, which has completed the cleaning task, to a safe height. Then, the second rotating component 30 rotates to position the wiping assembly 13 above the collection tank 60 on one side of the support platform 50. Next, the limiting structure (such as the three-sided sliding panel 126) releases the limiting force, causing the wiping assembly 13 to automatically detach from the mounting slot and fall into the collection tank 60 under the action of gravity, completing the automatic recycling process of the waste wiping assembly 13.

[0092] The inside of the collection tank 60 can be equipped with a cushioning pad or a partition to reduce the impact when the wiping component 13 falls and to organize it neatly. If necessary, a transparent window or a sensor can also be installed to monitor the collection status.

[0093] By adopting the above technical solution, by setting a collection trough 60 for collecting waste wiping components 13 on one side of the support platform 50, the automatic detachment and centralized collection of wiping components 13 after use are realized, reducing manual operation links and avoiding cross-interference between contaminated wiping components 13 and spare components or clean areas, significantly improving the automation level of the cleaning device and the cleanliness of the site.

[0094] In one embodiment of this application, a support plate 70 for supporting battery cells is provided on one side of the support platform 50.

[0095] Specifically, the support plate 70 is a horizontally arranged load-bearing structure, and its material can be a metal plate, stainless steel plate, or engineering plastic plate, possessing a certain strength and wear resistance. The support plate 70 is fixed to one side of the support platform 50 by welding, bolting, or modular insertion, forming a relatively fixed positional relationship with the entire wiping device.

[0096] The upper surface of the support plate 70 may be provided with several positioning grooves, limiting blocks or clamping mechanisms for precise positioning of the outer contour of the battery cell. The position of the support plate 70 is consistent with the working path of the wiping assembly 13, so that when the first telescopic member 11 extends and drives the wiping assembly 13 to move, the electrolyte wiping cloth 40 can accurately cover the electrolyte injection port area on the battery cell.

[0097] The battery cells can be manually placed onto the support plate 70 by an operator, or they can be combined with an automatic loading and unloading mechanism to achieve continuous loading and wiping operations. Depending on the model and size of the battery cells, the structure of the support plate 70 can also be designed as a replaceable module to easily adapt to various battery cell specifications.

[0098] To improve safety and compatibility, the support plate 70 may also be equipped with auxiliary structures such as an insulating layer, buffer pads, or battery cell clamping rails to further enhance load-bearing stability and operational reliability.

[0099] By adopting the above technical solution, by setting a support plate 70 for supporting the battery cell on one side of the support platform 50, the battery cell to be wiped can maintain a stable position during the operation of the device, which makes it easy for the wiping component 13 to accurately align with the battery cell liquid injection port for wiping operation, significantly improving the wiping accuracy and the overall reliability of the device operation, while reducing the risk of wiping failure or equipment damage caused by battery cell position deviation.

[0100] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
