Description

Technical Field

[0001] This application relates to the field of battery energy storage technology, and in particular to a cleaning device. Background Technology

[0002] Lithium-ion batteries, as crucial energy storage components in the new energy field, are widely used in electric vehicles, energy storage power stations, power tools, and consumer electronics. During the production, storage, transportation, and use of lithium-ion batteries, the surface of the battery pack is highly susceptible to the accumulation of dust, particulate matter, and other minute contaminants due to environmental factors such as airflow, electrostatic adsorption, and workshop dust. These contaminants not only affect the cleanliness of the lithium-ion battery pack but, more importantly, can have numerous adverse effects on its performance and lifespan.

[0003] Currently, there are two main methods for cleaning the surface of lithium battery packs. One is manual cleaning with a brush, which is not only inefficient but also difficult to thoroughly remove contaminants from all parts of the battery pack surface, especially for some complex lithium battery packs, where manual cleaning is unlikely to achieve the desired cleaning effect. The other method uses a cleaning device that only blows dust away, but this method cannot effectively collect dust. The blown-up dust may re-adhere to the lithium battery pack or other equipment, causing secondary pollution. Furthermore, for some firmly adhered dust and other contaminants, simple blowing is insufficient to remove them. Summary of the Invention

[0004] The purpose of this application is to provide a cleaning device that can prevent dust and other contaminants from flying in the cavity and causing secondary pollution to the battery, and ensure the cleaning effect of the battery; at the same time, it can prevent contaminants from escaping to the external environment and causing secondary pollution to other equipment.

The fixing frame includes a first plate and a second plate, which are located on both sides of the air intake. The first plate is provided with a limiting groove. The filter screen passes through the limiting groove and contacts the second plate. The connecting plate is connected to one side of the filter screen. The connecting plate is detachably connected to the side of the first plate that faces away from the second plate and covers the limiting groove.

[0011] In an optional embodiment, a sealing gasket is sandwiched between the connecting plate and the first plate portion.

[0012] In an optional embodiment, the clamping assembly includes a placement platform and a pushing member spaced apart along the length of the brush member, the pushing member being able to approach or move away from the placement platform to clamp or release the battery together with the placement platform.

[0013] In an optional embodiment, the clamping assembly further includes a second motor connected to the placement platform for driving the placement platform to rotate relative to the housing.

[0014] In an optional embodiment, the accommodating cavity is provided with a partition, which divides the accommodating cavity into a cleaning area and a driving area.

The positive pressure side of the fan is connected to the housing cavity, and the negative pressure side is connected to the air intake. This allows the fan to generate airflow through the battery during operation, so that the swept contaminants are quickly sucked into the air intake and intercepted by the filter. They are then adsorbed on the surface of the filter, preventing dust and other contaminants from flying around in the housing cavity and causing secondary pollution to the battery, and ensuring the battery's cleanliness. At the same time, since the entire cleaning process is completed inside the housing, it can prevent contaminants from escaping into the external environment and causing secondary pollution to other equipment.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] refer to Figures 1 to 3 This application discloses an embodiment of a cleaning device, which includes a housing 1, a cleaning component 2, a clamping component 3, and a fan 27; The housing 1 has a receiving cavity 11 and an air intake 10 communicating with the receiving cavity 11; Both the cleaning component 2 and the clamping component 3 are disposed in the receiving cavity 11, and the clamping component 3 is used to clamp the battery located in the receiving cavity 11; The cleaning component 2 includes a brush and a filter. The filter is located at the air intake 10, and the brush is located on the side of the filter away from the air intake 10. The brush and the clamping assembly 3 can move relative to each other so that the brush can remove contaminants from the surface of the battery; The fan 27 is fixed on the outside of the housing 1, and the negative pressure side of the fan 27 is connected to the air intake 10, while the positive pressure side is connected to the accommodating cavity 11.

[0029] In this way, by setting the brush and clamping assembly 3 to be relatively movable, the brush can make contact with and clean the surface of the battery in the clamped state, effectively removing contaminants from the battery surface. The positive pressure side of the fan 27 is connected to the accommodating cavity 11, and the negative pressure side is connected to the suction port 10. When the fan 27 is running, it can generate airflow through the battery, so that the swept contaminants are quickly sucked into the suction port 10 and intercepted by the filter, and finally adsorbed on the surface of the filter, preventing dust and other contaminants from flying in the accommodating cavity 11 and causing secondary pollution to the battery, and ensuring the cleaning effect of the battery. At the same time, since the entire cleaning process is completed inside the housing 1, it can prevent contaminants from escaping to the external environment and causing secondary pollution to other equipment.

[0030] The shape of box 1 is not specifically limited. For example, it can be a cuboid as shown in the figure, or it can be an ellipse or other polygonal shape not shown in the figure, etc.

[0031] The brush component can be rotatably connected to the housing 1. Specifically, refer to... Figures 2 to 4 The brush component includes a roller 24 and a plurality of bristles 240 distributed on the outer peripheral surface of the roller 24. The roller 24 is rotatably mounted on the housing 1. When the roller 24 rotates relative to the housing 1, the bristles 240 can brush the battery held by the clamping assembly 3 to remove contaminants from the battery surface.

[0032] The brush assembly also includes a first rotating shaft 28, and the fixed frame 21 is connected to a support plate 26. The idler roller 24 is coaxially mounted outside the first rotating shaft 28. The first rotating shaft 28 is rotatably connected to the support plate 26, so that the idler roller 24 can be driven to rotate by applying torque to the first rotating shaft 28.

[0033] The rotation of the brush can be automated by a power component. Specifically, the cleaning component 2 also includes a first motor 25, which is connected to the roller 24 via a first rotating shaft 28 to drive the first rotating shaft 28 to rotate. In this way, the first rotating shaft 28 can drive the roller 24 to rotate relative to the housing 1.

[0034] It is understood that in some embodiments, a handwheel may be connected to the first rotating shaft 28, and the rotation of the roller 24 may be achieved by manually turning the handwheel.

[0035] refer to Figure 5 The cavity 11 is provided with a partition, which divides the cavity 11 into a cleaning area 110 and a driving area 111. The cavity 11 is provided with a partition, which divides the cavity 11 into a cleaning area 110 and a driving area 111. The air intake 10 is connected to the cleaning area 110, and the positive pressure side of the fan 27 is connected to the cleaning area 110. The brush assembly is located within the cleaning zone 110, that is, the roller 24 and the bristles 240 are located within the cleaning zone 110, and the first rotating shaft 28 is rotatably mounted through the partition; the first motor 25 is located within the drive zone 111.

[0036] This opening divides the accommodating cavity 11 into a clean zone 110 for high-dust environments and a drive zone 111 for clean operation, forming a physical isolation barrier. The precision drive component, the first motor 25, is located within the drive zone 111, preventing direct exposure to dusty airflow. This effectively prevents contaminants from entering the first motor 25 and causing winding contamination, bearing wear, poor heat dissipation, or electrical short circuits, thus improving the operational reliability and service life of the drive system.

[0037] Of course, it is understandable that a dynamic seal design can be used between the first rotating shaft 28 and the partition to prevent contaminants from entering the drive area 111 through the gap between them.

[0038] During the cleaning process, dust, fibers, and tiny particles on the battery surface can easily get embedded in the gaps between the bristles 240, causing the bristles 240 to clump together and lose elasticity, thus affecting the cleaning effect.

[0039] Therefore, continue to refer to Figure 3 and Figure 4 In this embodiment, the cleaning component 2 also includes a scraper located between the filter and the roller 24. The scraper includes a fixing rod 23 and a plurality of comb teeth 230 disposed on the fixing rod 23. The plurality of comb teeth 230 are distributed along the length direction of the roller 24 and extend into the bristles 240.

[0040] In this way, by setting up a scraper with comb teeth 230, the bristles 240 can periodically pass through the gaps between the comb teeth 230 as they rotate with the roller 24, effectively removing the dust stuck at the base of the bristles 240 and in the gaps, maintaining the fluffiness and elasticity of the bristles 240, ensuring that the brush maintains its high-efficiency cleaning ability for a long time, and ensuring that the cleaning force on the battery surface is uniform and stable. Moreover, while cleaning the bristles 240, the comb teeth 230 also push or shake off the loosened dust into the airflow path, making it easier for the negative pressure airflow of the fan 27 to capture and guide it to the filter, thus preventing dust from accumulating near the brush body.

[0041] The filter element is located in the clean area 110. Specifically, the filter element includes a mounting bracket 21, a filter screen 29, and a connecting plate 22. The fixing frame 21 is located between the air intake 10 and the brush component. The fixing frame 21 includes a first plate portion 211 and a second plate portion 212. The first plate portion 211 and the second plate portion 212 are located on both sides of the air intake 10, wherein the first plate portion 211 is provided with a limiting groove 213. The filter screen 29 passes through the limiting groove 213 and contacts the second plate portion 212; The connecting plate 22 is connected to one side of the filter screen 29. The connecting plate 22 is detachably connected to the side of the first plate portion 211 that is opposite to the second plate portion 212, and covers the limiting groove 213.

[0042] Thus, the fixed frame 21, acting as the main load-bearing structure, spans across both sides of the air intake 10, forming a stable support frame. The filter screen 29, through the limiting groove 213 of the first plate 211, achieves axial positioning and lateral constraint, preventing it from shifting or shaking under airflow impact. Simultaneously, the filter screen 29 contacts the second plate 212, and the connecting plate 22 covers the limiting groove 213, creating a tight fit between the filter screen 29 and the fixed frame 21. This effectively seals the gaps around the air intake 10, preventing dust-laden airflow from bypassing the filter screen 29 and directly entering the fan 27, ensuring all airflow is filtered, improving dust removal efficiency and emission cleanliness. The connecting plate 22 is detachably connected to the outer side of the first plate 211 (e.g., by screws, clips, or quick-release strips), allowing the filter screen 29 to be easily removed along the limiting groove 213 when cleaning or replacement is needed. This simple operation eliminates the need to disassemble the housing 1 or other components, shortening maintenance time and improving equipment availability.

[0043] The specific material of the filter 29 can be selected according to actual needs, such as primary non-woven fabric, medium-efficiency F8 filter cotton, HEPA high-efficiency filter 29 or metal mesh, etc. Quick replacement can be achieved through the unified limiting groove 213 and connection structure to meet different cleanliness levels.

[0044] A sealing gasket is sandwiched between the connecting plate 22 and the first plate portion 211. The sealing gasket fills the tiny gap between the connecting plate 22 and the first plate portion 211, forming a reliable static sealing barrier, completely blocking the bypass airflow path, and ensuring that all airflow is forced to pass through the filter screen 29, thereby improving dust removal efficiency and emission cleanliness.

[0045] The sealing gaskets can be made of elastic materials that are resistant to aging, temperature, and corrosion (such as rubber, silicone, EPDM, or polyurethane foam), which can maintain sealing performance for a long time, are not easy to crack or harden, and ensure that the equipment maintains a high sealing level during long-term continuous operation.

[0046] In this embodiment, the clamping assembly 3 is used to clamp the battery located in the cleaning area 110. Specifically, the clamping assembly 3 includes a placement platform 31 and a pushing member that are spaced apart along the length of the brush member. The pushing member can move closer to or away from the placement platform 31 to clamp or release the battery together with the placement platform 31.

[0047] In this way, the placement platform 31 and the pushing component are distributed along the length of the brush component. By adjusting the stroke or position of the pushing component, lithium battery packs of different heights can be adapted without changing the fixtures, meeting the needs of multi-model mixed production lines and enhancing the flexibility and compatibility of the equipment.

[0048] Continue to refer to Figure 5 The clamping assembly 3 also includes a second motor 35, which is connected to the placement platform 31 and drives the placement platform 31 to rotate relative to the housing 1. Thus, by driving the placement platform 31 to rotate via the second motor 35, the clamped battery can be adjusted in angle or rotated 360 degrees during the cleaning process. For example, the battery can be flipped from front to side or back, allowing the brush to sequentially remove dust from different surfaces without manual intervention or repeated clamping, improving the comprehensiveness and automation of the cleaning process. Furthermore, the rotational motion of the placement platform 31 and the rotation of the brush create a composite motion trajectory, resulting in more complex relative sliding between the bristles 240 and the battery surface, enhancing the ability to peel off firmly attached dust.

[0049] The second motor 35 is specifically located within the drive area 111 of the accommodating cavity 11; this avoids direct exposure to dusty airflow, effectively preventing contaminants from entering the interior of the second motor 35 and causing winding contamination, bearing wear, poor heat dissipation, or electrical short circuits, thereby improving the operational reliability and service life of the drive system.

[0050] The clamping assembly 3 also includes a second rotating shaft 34, a first gear 36 and a second gear 37. One end of the second rotating shaft 34 is connected to the placement platform 31. The first gear 36 is mounted on the output shaft of the second motor 35, and the second gear 37 is mounted on the second rotating shaft 34. The first gear 36 and the second gear 37 mesh.

[0051] In this way, the rotational power of the second motor 35 is accurately and smoothly transmitted to the second rotating shaft 34 through the meshing of the first gear 36 and the second gear 37, thereby driving the placement platform 31 to rotate. The gear meshing has the characteristics of strong load-bearing capacity, constant transmission ratio, and no slippage, ensuring smooth operation of the battery during the flipping process.

[0052] Of course, it is understandable that a dynamic seal design can be used between the second rotating shaft 34 and the partition to prevent contaminants from entering the drive area 111 through the gap between them.

[0053] The pushing component includes a connected electric push rod 32 and a pressure plate 33. The electric push rod 32 passes through the box wall of the box body 1, and the pressure plate 33 is located in the clean area 110 of the accommodating cavity 11 and is opposite to the placement table 31.

[0054] Thus, by using an electric push rod 32 as the actuator, its extension and retraction stroke and speed can be precisely controlled by electrical signals to achieve automatic clamping and release of the battery by the pressure plate 33. This process can be programmed in conjunction with the dust removal process without manual intervention, meeting the high automation and unmanned operation requirements of lithium battery production lines. Moreover, the output force of the electric push rod 32 is stable and adjustable, and the appropriate clamping pressure can be set according to different battery models. This ensures that the battery does not shift or vibrate during cleaning, and also prevents shell deformation, coating scratches, or internal structural damage caused by excessive clamping force, effectively protecting the battery.

[0055] Additionally, it should be noted that in some embodiments, the brush can move in a circular motion around the placement platform 31 to achieve relative movement between the brush and the clamping assembly 3. Alternatively, the brush can move in a straight line, and the battery can be rotated by the rotation of the placement platform 31, thus achieving the dust removal operation. A handwheel can also be connected to the second rotating shaft 34, allowing the placement platform 31 to rotate manually.

[0056] Understandably, there is no specific limit to the number of cleaning components 2; it can be two as shown in the diagram, or one or more not shown in the diagram.

[0057] exist Figures 1 to 5 In the embodiment shown, the fan 27 can be installed on the top side wall of the housing 1, and the air inlet 10 can be located on the left and right side walls of the housing 1. The corresponding cleaning components 2 are also distributed left and right in the accommodating cavity 11. At this time, the clamping component 3 is located between the two cleaning components 2, and the two fans 27 are located on both sides of the electric push rod 32. In this way, the two cleaning components 2 can clean the battery surface from two directions at the same time, realize multi-angle and all-round contact cleaning of the battery surface, effectively remove dust accumulation in gaps and dead corners, and improve cleaning coverage and uniformity.

[0058] Of course, in order to facilitate the placement of batteries into the cleaning area 110 for cleaning or the removal of batteries that have been cleaned, an open structure is provided on one side wall of the housing 1, and a hinged door 5 is provided. This allows batteries to be placed or removed when the door 5 is open, and the door 5 is closed when cleaning is performed, thereby ensuring the airtightness of the entire housing 11.

[0059] The negative pressure side of the fan 27 and the air inlet 10 can be connected by the air pipe 4 to ensure the airtightness of the internal circulation of the entire device.

[0060] The working principle of the cleaning device of this application is illustrated below: Open the box door 5, place the lithium battery pack to be dusted on the top of the placement platform 31, start the electric push rod 32, the push rod end of the electric push rod 32 pushes the pressure plate 33 downward to press and fix the lithium battery pack on the placement platform 31 to prevent the lithium battery pack from moving during the dust removal process; When the second motor 35 is started, its output shaft drives the first gear 36 to rotate. The first gear 36 meshes with the second gear 37, which is fixedly sleeved on the outside of the second rotating shaft 34, thereby driving the second gear 37 to rotate, which in turn drives the second rotating shaft 34 to rotate. The placement platform 31 rotates accordingly, which causes the lithium battery pack placed on the placement platform 31 to start rotating. The first motor 25 is started, and the output shaft of the first motor 25 drives the first rotating shaft 28 to rotate. The roller 24 rotates accordingly. As the roller 24 rotates, the bristles 240 continuously contact the surface of the rotating lithium battery pack, brushing off the dust on the surface of the lithium battery pack. At the same time, the fan 27 is controlled to work. The dust falling from the surface of the lithium battery pack is adsorbed and enters the inner side of the fixed frame 21 with the airflow, and finally adsorbs on the surface of the filter screen 29, preventing dust from flying in the box 1 and causing secondary pollution. The clean airflow is sent to the negative pressure side of the fan 27 through the air pipe 4. During the rotation of the bristles 240, the comb teeth 230 scrape off the hair and other impurities attached to the surface of the bristles 240, ensuring the cleanliness of the bristles 240 and improving the cleaning effect. The impurities scraped off on the comb teeth 230 can be cleaned periodically. After the surface of the lithium battery pack is cleaned, the first motor 25, the second motor 35 and the fan 27 are turned off in sequence. The electric push rod 32 is started so that its push rod end retracts, driving the pressure plate 33 to move upward, releasing the pressure on the lithium battery pack. The box door 5 is opened, and the cleaned lithium battery pack is taken out from the placement table 31, completing the entire dust removal process.

[0061] After the cleaning device has been running for a period of time, the connecting plate 22 can be removed, the filter screen 29 can be pulled out from the limiting groove 213, the filter screen 29 can be cleaned, and the dust adsorbed on the surface of the filter screen 29 can be removed. After cleaning, the filter screen 29 can be reinstalled in its original position.

[0062] 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.
