[0056] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0057] In existing technologies, when cleaning aluminum shells, the aluminum shell is typically placed in a cleaning tank, a cleaning solution is injected into the tank, and then an ultrasonic cleaner is used to ultrasonically clean the aluminum shell. However, after the aluminum shell is cleaned in the cleaning tank, contaminants on the aluminum shell will fall into the cleaning solution. When the aluminum shell is removed from the cleaning solution, it may come into contact with contaminants in the cleaning solution again, causing the contaminants to adhere to the aluminum shell, resulting in secondary contamination and poor cleaning effect.

[0058] Based on this, this application provides a cleaning device, including a support frame, a fixing mechanism, a rinsing mechanism, a spraying mechanism, and an ultrasonic mechanism. The support frame has a cleaning chamber, and the fixing mechanism is disposed within the cleaning chamber to fix the part to be cleaned. The rinsing mechanism, spraying mechanism, and ultrasonic mechanism are mounted on the support frame. The rinsing mechanism sprays cleaning fluid onto the part to be cleaned, the spraying mechanism sprays cleaning fluid into the interior of the part to be cleaned, and the ultrasonic mechanism performs ultrasonic cleaning on the part to be cleaned. By providing the fixing mechanism, the part to be cleaned is fixed within the cleaning chamber, facilitating cleaning by the rinsing and spraying mechanisms. The rinsing mechanism, spraying mechanism, and ultrasonic mechanism respectively perform rinsing, spraying, and ultrasonic cleaning on the part to be cleaned, using different cleaning methods to clean the part. Simultaneously, the rinsing mechanism sprays cleaning fluid onto the part to be cleaned for large-area rinsing, thereby washing away contaminants on the surface of the part to be cleaned. The spraying mechanism sprays cleaning fluid into the interior of the part to be cleaned, thereby removing contaminants from the interior and preventing secondary contamination. This results in better cleaning performance from the cleaning equipment.

[0059] The embodiments of this application are described below with reference to the accompanying drawings.

[0060] Reference Figures 1 to 6 This application provides a cleaning device, including: a support frame 100, a fixing mechanism 200, a rinsing mechanism 300, a spraying mechanism 400, and an ultrasonic mechanism 500. The support frame 100 has a cleaning chamber 110, and the fixing mechanism 200 is disposed in the cleaning chamber 110 for fixing the part to be cleaned. The rinsing mechanism 300, the spraying mechanism 400, and the ultrasonic mechanism 500 are disposed on the support frame 100. The rinsing mechanism 300 is used to spray cleaning fluid onto the part to be cleaned, the spraying mechanism 400 is used to spray cleaning fluid into the interior of the part to be cleaned, and the ultrasonic mechanism 500 is used to perform ultrasonic cleaning on the part to be cleaned.

[0061] In this embodiment, the part to be cleaned can be a machined part, such as a battery casing 10. The battery casing 10 has a hollow structure and openings at both ends. For example, the battery casing 10 is an aluminum casing. The aluminum casing has a wall thickness of 0.1mm-1.2mm, a length of 200mm-1400mm, a cross-sectional width of 80mm-310mm, a cross-sectional height of 10mm-30mm, and a width-to-height ratio of 2-15:1.

[0062] The cleaning fluid in this embodiment can be adapted to the parts to be cleaned and actual needs. The cleaning fluid can be water or other cleaning solvents, and this embodiment does not limit it.

[0063] In practice, the part to be cleaned is first fixed in the cleaning chamber 110 by the fixing mechanism 200, and then the part to be cleaned can be cleaned by at least one of the rinsing mechanism 300, the spraying mechanism 400 and the ultrasonic mechanism 500.

[0064] It is understandable that when cleaning the workpiece is performed by two or more of the rinsing mechanism 300, spraying mechanism 400 and ultrasonic mechanism 500, the cleaning sequence can be adapted to actual needs.

[0065] For example, the cleaning solution can first be sprayed onto the workpiece to be cleaned by the rinsing mechanism 300 to rinse the workpiece, then the cleaning solution can be injected into the cleaning chamber 110 to immerse the workpiece in the cleaning solution, and then the ultrasonic mechanism 500 can be used to perform ultrasonic cleaning on the workpiece. Finally, the cleaning solution can be sprayed onto the workpiece to be cleaned by the spraying mechanism 400.

[0066] The cleaning equipment provided in this embodiment uses a fixing mechanism 200 to fix the part to be cleaned within the cleaning chamber 110, facilitating cleaning by the rinsing mechanism 300 and the spraying mechanism 400. The rinsing mechanism 300, the spraying mechanism 400, and the ultrasonic mechanism 500 respectively perform rinsing, spraying, and ultrasonic cleaning on the part to be cleaned, employing different cleaning methods. Simultaneously, the rinsing mechanism 300 sprays cleaning fluid onto the part to perform large-area rinsing, thereby removing contaminants from the surface. The spraying mechanism 400 sprays cleaning fluid into the interior of the part to remove internal contaminants and prevent secondary contamination. Therefore, the cleaning equipment achieves good cleaning results.

[0067] Reference Figure 1 and Figure 2 In some embodiments, the support frame 100 includes a support plate 120 located at the bottom of the cleaning chamber 110, and a fixing mechanism 200 is disposed on the support plate 120. The support plate 120 has a first end 121 and a second end 122 opposite to each other, and the height of the first end 121 is greater than the height of the second end 122.

[0068] In this configuration, the first end 121 is higher than the second end 122, meaning the support plate 120 is inclined relative to the horizontal plane. When the battery casing 10 is fixed by the fixing mechanism 200, the inclination direction of the support plate 120 is the same as the extension direction of the battery casing 10. The rinsing mechanism 300 sprays cleaning fluid toward the opening on the side of the battery casing 10 closest to the first end 121, and the spraying mechanism 400 also sprays cleaning fluid toward the opening on the side of the battery casing 10 closest to the first end 121. The cleaning fluid inside the battery casing 10 can flow along the battery casing 10 under the action of gravity and flow out through the opening on the side of the battery casing 10 closest to the second end 122, thereby cleaning the battery casing 10. At the same time, the used cleaning fluid flows out of the battery casing 10 in a timely manner, reducing the contact between the battery casing 10 and the used cleaning fluid, and reducing secondary contamination of the battery casing 10 by contaminants in the used cleaning fluid.

[0069] For example, the angle between the support plate 120 and the horizontal plane is greater than or equal to 10 degrees and less than 90 degrees.

[0070] Reference Figure 1 , Figure 2 and Figure 4 In a specific implementation, the rinsing mechanism 300 includes at least one first mounting member 310 and at least one first spray member 320. The first spray member 320 is disposed on the first mounting member 310. The first mounting member 310 is connected to the support frame 100. The first spray member 320 is used to spray towards the first end 121.

[0071] The first mounting component 310 connects to the support frame 100, thereby connecting the flushing mechanism 300 to the support frame. The first spray component 320 sprays cleaning fluid toward the opening at the higher end of the battery casing 10. The cleaning fluid with a certain pressure enters the battery casing 10 through the opening at the higher end of the battery casing 10 and forms turbulence on the inner surface of the battery casing 10. The turbulence can quickly and effectively remove contaminants from the inner surface of the battery casing 10, and the cleaning effect is good.

[0072] Reference Figure 4 In a specific implementation, the first spraying component 320 includes a first spray bar 321 and a first nozzle 322 communicating with the first spray bar 321. The first spray bar 321 is connected to the first mounting component 310, and the end face of the first nozzle 322 is used to be parallel to the end face of the component to be cleaned.

[0073] The end face of the first nozzle 322 is parallel to the end face of the battery case 10 near the first end 121. The end face of the battery case 10 is perpendicular to the extension direction of the battery case 10. In other words, the plane containing the end face of the first nozzle 322 is perpendicular to the extension direction of the battery case 10, so that the direction in which the cleaning fluid is sprayed from the first nozzle 322 is the same as the extension direction of the battery case 10, thereby facilitating the entry of the cleaning fluid sprayed from the first nozzle 322 into the battery case 10.

[0074] Specifically, the cleaning fluid flows through the first spray bar 321 into the first nozzle 322 and is sprayed out through the first nozzle 322. The first nozzle 322 has a nozzle, and the cleaning fluid in the first nozzle 322 is sprayed out through the nozzle. The end face of the first nozzle 322 is the end face where the nozzle is located.

[0075] Furthermore, the rinsing mechanism 300 also includes at least one inlet pipe 350, which is connected to each of the first spray bars 321 to provide cleaning fluid to the first spray bars 321. The rinsing mechanism 300 also includes at least one connecting pipe, which connects each of the first spray bars 321 and the inlet pipe 350.

[0076] For example, the shape of the end face of the first nozzle 322 is the same as the shape of the end face of the battery casing 10 near the first end, and the size of the end face of the first nozzle 322 is slightly smaller than the size of the end face of the battery casing 10 near the first end, so that the cleaning fluid sprayed from the first nozzle 322 can enter the battery casing 10. For example, the shape of the end face of the first nozzle 322 and the shape of the end face of the battery casing 10 near the first end 121 are both rectangular, the length and width of the end face of the first nozzle 322 are smaller than the length and width of the end face of the battery casing 10 near the first end 121, and the difference between the length and width of the end face of the first nozzle 322 and the length and width of the end face of the battery casing 10 near the first end 121 can be 1mm-6mm.

[0077] Reference Figure 1 and Figure 4 In some embodiments, the rinsing mechanism 300 is located above the support plate 120. The rinsing mechanism 300 also includes at least one lifting member 330. The lifting member 330 connects the first mounting member 310 and the support frame 100. The lifting member 330 drives the first mounting member 310 and the first spraying member 320 to rise and fall relative to the support frame 100 so that the first spraying member 320 is opposite to the part to be cleaned.

[0078] Specifically, both the rinsing mechanism 300 and the spraying mechanism 400 are located around the first end 121 to allow the rinsing mechanism 300 and the spraying mechanism 400 to spray cleaning fluid toward the opening of the battery casing 10 near the first end 121. To prevent interference between the rinsing mechanism 300 and the spraying mechanism 400 and thus affect the spraying of cleaning fluid by the spraying mechanism 400 toward the battery casing 10, a lifting member 330 is provided on the rinsing mechanism 300, allowing the rinsing mechanism 300 to move up and down along the support frame 100, thereby allowing the rinsing mechanism 300 to avoid the spraying mechanism 400.

[0079] Furthermore, the rinsing mechanism 300 also includes at least a first connecting plate 360, and the lifting component 330 includes at least one first cylinder 331, at least one first guide rod 332, and at least one first linear bearing 333. The first connecting plate 360 ​​is connected to the support frame 100, the first guide rod 332 connects the first mounting component 310 and the first connecting plate 360, the first linear bearing 333 is connected to the first guide rod 332, and the first cylinder 331 connects the first connecting plate 360 ​​and the first mounting component 310. By setting the first guide rod 332 and the first linear bearing 333, the stability of the lifting of the first mounting component 310 and the first spray component 320 is improved. The floating joint of the first cylinder 331 is connected to the first mounting component 310.

[0080] For example, there are two lifting components 330, and the two lifting components 330 are respectively connected to opposite sides of the first mounting component 310. The first connecting plate 360 ​​is correspondingly provided with the lifting components 330.

[0081] In some examples, the first cylinder 331 may also be replaced by a hydraulic cylinder or other drive structure.

[0082] In a specific implementation, the first mounting component 310 has a first clearance hole 311, and one side of the cleaning chamber 110 has a second clearance hole 114. The first spraying component 320 extends into the cleaning chamber 110 in sequence through the first clearance hole 311 and the second clearance hole 114, and can move up and down along the first clearance hole 311 and the second clearance hole 114.

[0083] Reference Figure 1 and Figure 4 In a specific implementation, the rinsing mechanism 300 also includes a first moving member 340, which connects the first mounting member 310 and the first spraying member 320. The first moving member 340 drives the first spraying member 320 to move relative to the first mounting member 310.

[0084] The first moving member 340 can drive the first spraying member 320 to move along the setting direction of each battery case 10, so that the first nozzle 322 is opposite to different battery cases 10, thereby facilitating the rinsing mechanism 300 to clean different battery cases 10.

[0085] For example, the first moving member 340 is a linear module. The linear module can be connected to the first mounting member 310 via a mounting plate.

[0086] In some examples, both the lifting member 330 and the first moving member 340 are connected to the side of the first mounting member 310 away from the cleaning chamber 110, thereby blocking the cleaning fluid through the periphery of the first clearance hole 311 and the second clearance hole 114, preventing the cleaning fluid from splashing onto the lifting member 330 and the first moving member 340.

[0087] ReferenceFigure 1 , Figure 2 , Figure 5 and Figure 6 In some embodiments, the spraying mechanism 400 includes at least one second moving member 410 and at least one second spraying member 420. The second moving member 410 connects the second spraying member 420 to the support frame 100. The second spraying member 420 is used to spray cleaning liquid into the part to be cleaned. The second moving member 410 drives the second spraying member 420 to move relative to the support frame 100 so that the second spraying member 420 extends into the part to be cleaned through the first end 121 and moves along the part to be cleaned.

[0088] Specifically, the second spray nozzle 420 extends into the battery casing 10 and reciprocates along the battery casing 10 to clean the inner surface of the battery casing 10. In particular, the second spray nozzle 420 sprays cleaning fluid onto the weld seams inside the battery casing 10 under pressure, effectively removing burrs and weld slag from the weld seams inside the battery casing 10, thus preventing short circuits caused by burrs and weld slag from the weld seams inside the battery casing 10.

[0089] For example, the second spraying element 420 is inclined relative to the horizontal plane, and the extending direction of the second spraying element 420 is the same as the extending direction of the battery housing 10. The second moving element 410 drives the second spraying element 420 to move along the extending direction of the second spraying element 420. It can be understood that the second spraying element 420 can be configured in a one-to-one correspondence with the battery housing 10.

[0090] In some examples, the second moving part 410 is a linear module.

[0091] In a specific implementation, the second spraying component 420 includes a second spray bar 421 and a second nozzle 422, with the second nozzle 422 connected to the second spray bar 421.

[0092] The second nozzle 422 has at least one spray hole 423 for spraying cleaning fluid onto the inner wall of the battery casing 10. The cleaning fluid flows into the second nozzle 422 via the second spray bar 421 and is sprayed onto the inner surface of the battery casing 10 through the spray hole 423. The spray hole 423 has clearance grooves on at least two sides to allow the cleaning fluid to be sprayed through at least two sides of the spray hole 423, thereby expanding the spray coverage area of ​​the spray hole 423.

[0093] It is understood that the specific shape of the nozzle 423 can be adapted to actual needs to adjust the spray coverage range of the nozzle 423, and this embodiment does not impose any restrictions on it.

[0094] In a specific implementation, the shape of the second nozzle 422 is used to match the battery housing 10, and the projection of the second spray bar 421 on the second nozzle 422 is located inside the second nozzle 422.

[0095] The second nozzle 422 has the same cross-sectional shape as the battery casing 10, but its cross-sectional size is slightly smaller than that of the battery casing 10, allowing it to enter the battery casing 10 more easily. The second spray bar 421 has a smaller cross-sectional size than the second nozzle 422, ensuring that it does not contact the inner surface of the battery casing 10 when the second nozzle 422 moves within the battery casing 10, thus preventing damage to the battery casing 10.

[0096] For example, the hardness of the second nozzle 422 is less than that of the battery casing 10, so as to avoid damage to the battery casing 10 when the second nozzle 422 moves inside the battery casing 10.

[0097] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 In some embodiments, the spraying mechanism 400 further includes a second mounting member 430 and at least one guide member 440. The second mounting member 430 connects the support frame 100 and the second movable member 410, and the guide member 440 connects the second mounting member 430 and the second spray bar 421. The guide member 440 is configured to provide guidance for the second spray bar 421 when it moves.

[0098] The second mounting member 430 is provided to facilitate the connection between the second movable member 410 and the support frame 100. A guide member 440 is provided on the second mounting member 430 to guide the second spray bar 421, thereby ensuring that the second spray bar 421 can move stably and accurately along its extension direction. This ensures that the second nozzle 422 and the second spray bar 421 are less likely to collide with the battery housing 10 when moving within the battery housing 10, preventing damage to the battery housing 10.

[0099] For example, the second mounting member 430 is inclined relative to the horizontal plane and parallel to the support plate 120. The second mounting member 430 is located on the side of the first end 121 away from the second end 122. The second moving member 410 and the second spraying member 420 are connected to the second mounting member 430. The second moving member 410 drives the second spraying member 420 to move toward the support plate 120 so that the second spraying member 420 extends into the battery case 10, thereby cleaning the inside of the battery case 10.

[0100] Furthermore, the spraying mechanism 400 also includes at least one liquid inlet, which is connected to each of the second spray bars 421 to provide cleaning fluid to the second spray bars 421.

[0101] In some examples, the guide 440 includes a slide rail 441, and the spray mechanism 400 further includes at least one third mounting member 450, which is slidably connected to the slide rail 441. The third mounting member 450 connects the second moving member 410 and a plurality of second spray bars 421. The second moving member 410 drives the third mounting member 450 to slide along the slide rail 441, thereby causing the second spray bars 421 to slide along the slide rail 441, thus ensuring that the movement of the second spray bars 421 is relatively accurate.

[0102] The guide 440 also includes at least one limiting block 442, which is connected to at least one end of the slide rail 441 to limit the movement of the third mounting member 450 on the slide rail 441.

[0103] The third mounting component 450 includes a pressure plate 451, a side plate 452, and a base plate 453. The pressure plate 451 is located above and connected to the base plate 453. The side plate 452 is located on one side of the pressure plate 451 and the base plate 453, and is connected to at least one of the pressure plate 451 and the base plate 453. The pressure plate 451 is connected to a plurality of second spray bars 421, the side plate 452 is connected to a second moving member 410, and at least one of the base plate 453 and the side plate 452 is slidably connected to a slide rail 441.

[0104] The spraying mechanism 400 also includes a mounting base 460 and multiple limiting wheels 470. The limiting wheels 470 are mounted on the mounting base 460, which is connected to the side of the second mounting member 430 near the support plate 120. The second spray bars 421 are connected to the limiting wheels 470 one by one and can roll on the limiting wheels 470. By setting the limiting wheels 470, the movement direction of the second spray bars 421 is further restricted to ensure that the movement direction of the second spray bars 421 is accurate, thereby avoiding collision between the second spray bars 421 and the second nozzles 422 and the battery casing 10.

[0105] Reference Figure 1 , Figure 2 and Figure 8 In some embodiments, the cleaning device provided in this application further includes at least one first sealing mechanism 600. The cleaning chamber 110 has at least one first opening 111 on the side near the first end 121. The first opening 111 is located between the cleaning chamber 110 and the spraying mechanism 400. The second spraying element 420 can be moved at least partially into the cleaning chamber 110 through the first opening 111. The first sealing mechanism 600 is used to open or close the first opening 111.

[0106] Specifically, when the spraying mechanism 400 needs to clean the battery case 10 inside the cleaning chamber 110, the first opening 111 is opened by the first sealing mechanism, allowing the second spraying component 420 to move into the cleaning chamber 110 through the first opening 111 and extend into the battery case 10 to clean it. When the spraying mechanism 400 is not needed to clean the battery case 10, the first opening 111 is closed by the first sealing mechanism 600 to prevent the cleaning liquid inside the cleaning chamber 110 from splashing out or overflowing through the first opening 111.

[0107] In a specific implementation, the first closing mechanism 600 includes at least one first closing member 610, at least one first driving member 620, at least one second driving member 630, and at least one first connecting member 640. The first connecting member 640 is connected to the support frame 100. The first driving member 620 connects the second driving member 630 and the first connecting member 640. The second driving member 630 is connected to the first closing member 610. The first driving member 620 drives the second driving member 630 and the first closing member 610 to move along a first direction. The second driving member 630 drives the first closing member 610 to move along a second direction, so that the first closing member 610 opens or closes the first opening 111.

[0108] The first opening 111 and the first closing member 610 are respectively provided. Both ends of the first connecting member 640 are connected to the support frame 100 to ensure good stability of the connection between the first connecting member 640 and the support frame 100.

[0109] For example, the first driving member 620 drives the second driving member 630 and the first closing member 610 to move vertically, and the second driving member 630 drives the first closing member 610 to move horizontally. Both the first driving member 620 and the second driving member 630 can be cylinders or hydraulic cylinders.

[0110] Specifically, when it is necessary to open the first opening 111, the second driving member 630 drives the first closing member 610 to move toward the side away from the first opening 111, so that the first closing member 610 opens the first opening 111. At this time, the first closing member 610 is located between the first opening 111 and the spraying mechanism 400. In order to avoid interference between the spraying mechanism 400 and the first closing member 610 and affect the spraying of the spraying mechanism 400, the first driving member 620 drives the second driving member 630 to move in the vertical direction. The second driving member 630 can drive the first closing member 610 to move in the vertical direction, thereby causing the first closing member 610 to move away from the first opening 111 and the spraying mechanism 400.

[0111] In some embodiments, the first closure mechanism 600 further includes a third connector 660 and a fourth connector 670. The first drive member 620 includes at least one second cylinder 621, at least one second guide rod 622, and at least one second linear bearing 623. The second drive member 630 includes at least one third cylinder 631, at least one third guide rod 632, and at least one third linear bearing 633. The third connector 660 is connected to the first connector 640, the second cylinder 621 and the second guide rod 622 connect the third connector 660 to the fourth connector 670, and the second linear bearing 623 is connected to the second guide rod 622. The third cylinder 631 and the third guide rod 632 connect the fourth connector 670 to the first closure member 610, and the third linear bearing 633 is connected to the third guide rod 632. By providing the second guide rod 622, the second linear bearing 623, the third guide rod 632, and the third linear bearing 633, the stability of the movement of the first closure member 610 is improved.

[0112] Furthermore, the fourth connector 670 includes a second connector 671 and a third connector 672. The second connector 671 is connected to one side of the third connector 672. The first drive member 620 is connected to the second connector 671, and the second drive member 630 is connected to the third connector 672.

[0113] In a specific implementation, the first sealing mechanism 600 further includes at least one first sealing member 650, which is disposed on the side of the first sealing member 610 facing away from the second driving member 630. The first sealing member 650 is used to seal the connection between the first sealing member 610 and the first opening 111.

[0114] The first seal 650 has a compression amount of 2-6 mm to compensate for the flatness of the sealing surface of the first opening 111, thereby sealing the first opening 111.

[0115] Thus, by setting the first sealing element 650, the sealing performance of the first opening 111 is improved, further preventing the cleaning fluid in the cleaning chamber 110 from seeping out or leaking through the first opening 111.

[0116] Reference Figure 1 and Figure 2 In some embodiments, the ultrasonic mechanism 500 is disposed on the side of the support plate 120 opposite to the cleaning chamber 110.

[0117] For example, the ultrasonic mechanism 500 includes an ultrasonic generator and an ultrasonic transducer, the ultrasonic transducer being disposed on one side of the Berry cleaning chamber 110 of the support plate.

[0118] Specifically, cleaning fluid can be injected into the cleaning chamber 110 through at least one of the rinsing mechanism 300 and the spraying mechanism 400. When the battery case 10 is completely immersed in the cleaning fluid, the ultrasonic mechanism 500 is activated to perform ultrasonic cleaning on the battery case 10.

[0119] Reference Figure 1 and Figure 2 In some embodiments, the support frame 100 has a drain port 130, which is connected to the cleaning chamber 110 and is located on the side of the second end 122 away from the first end 121.

[0120] Specifically, the second end 122 is lower than the first end 121, and a drain port 130 is provided on the side of the second end 122 away from the first end 121, so that the cleaning fluid in the cleaning chamber 110 can flow to the second end 122 under gravity and be discharged through the drain port 130. While the battery case 10 in the cleaning chamber 110 is being cleaned by the rinsing mechanism 300 and the spraying mechanism 400, the used cleaning fluid can be discharged through the drain port 130, thereby preventing the battery case 10 from coming into contact with the used cleaning fluid and avoiding secondary contamination of the battery case 10 by contaminants in the used cleaning fluid.

[0121] Reference Figure 1 , Figure 2 and Figure 9 In a specific implementation, the battery casing cleaning device provided in this application embodiment further includes at least one second sealing mechanism 700. The cleaning chamber 110 has at least one second opening 112 on the side near the second end 122. The second opening 112 connects the cleaning chamber 110 and the drain port 130. The second sealing mechanism 700 is used to open or close the second opening 112.

[0122] When the second opening 112 is open, the cleaning chamber 110 is connected to the drain port 130, so that the cleaning fluid in the cleaning chamber 110 can be discharged through the drain port 130. When the second opening 112 is closed, the cleaning chamber 110 is not connected to the drain port 130, so that the cleaning fluid in the cleaning chamber 110 cannot flow out through the drain port 130.

[0123] Specifically, when the battery casing 10 is ultrasonically cleaned by the ultrasonic mechanism 500, the second opening 112 is closed by the second sealing mechanism 700 to prevent the cleaning fluid in the cleaning chamber 110 from being discharged sequentially through the second opening 112 and the drain port 130. When the battery casing 10 is cleaned by the rinsing mechanism 300 and the spraying mechanism 400, the second opening 112 is opened by the second sealing mechanism to allow the cleaning fluid in the cleaning chamber 110 to be discharged sequentially through the second opening 112 and the drain port 130.

[0124] Reference Figure 2 and Figure 8In a specific implementation, the second closing mechanism 700 includes at least one second closing member 710, at least one second connecting member 720, and at least one third driving member 730. The second connecting member 720 connects the third driving member 730 to the second closing member 710. The second connecting member 720 is connected to the support frame 100. The third driving member 730 drives the second closing member 710 to move toward the second connecting member 720 or toward the side away from the second connecting member 720, so as to open or close the second opening 112 through the second closing member 710.

[0125] For example, the third drive member 730 includes at least one fourth cylinder 731, at least one fourth guide rod 732, and at least one fourth linear bearing 733. The fourth cylinder 731 and the fourth guide rod 732 are connected to the second closure member 710 and the second connecting member 720. The fourth linear bearing 733 is connected to the fourth guide rod 732. The fourth cylinder 731 drives the second closure member 710 to move.

[0126] In some embodiments, the second closing mechanism 700 further includes a synchronizing element 750, and the number of third driving elements 730 is multiple. The synchronizing element 750 connects each third driving element 730 so that each third driving element synchronously drives the second closing element 710 to move.

[0127] In some examples, the fourth cylinder 731 may also be replaced by a hydraulic cylinder or other drive structure.

[0128] In a specific implementation, the second sealing mechanism 700 further includes at least one second sealing member 740, which is disposed on the side of the second sealing member 710 facing away from the second connecting member 720. The second sealing member 740 is used to seal the connection between the second sealing member 710 and the second opening 112.

[0129] The second seal 740 has a compression amount of 2-6 mm to compensate for the flatness of the sealing surface of the second opening 112, thereby sealing the second opening 112.

[0130] Thus, by providing a second seal 740, the sealing performance of the second opening 112 is improved, further preventing the cleaning fluid in the cleaning chamber 110 from seeping out or leaking through the second opening 112.

[0131] Reference Figure 1 In some embodiments, the cleaning equipment provided in this application further includes a filtration mechanism 800, which is connected to the drain port 130 and at least one of the rinsing mechanism 300 and the spraying mechanism 400. The filtration mechanism 800 is used to filter the cleaning liquid discharged through the drain port 130 and deliver it to at least one of the rinsing mechanism 300 and the spraying mechanism 400.

[0132] The cleaning solution is filtered by the filtration mechanism 800 and then transported to the rinsing mechanism 300 and the spraying mechanism 400 for reuse. This allows for the recycling of the cleaning solution, reducing its discharge and loss.

[0133] In some embodiments, the support frame 100 has a receiving groove 140 located below the drain port 130. The receiving groove 140 is used to receive cleaning fluid, and the filter mechanism 800 is in communication with the receiving groove 140.

[0134] The cleaning fluid discharged through the drain port 130 is collected in a receiving tank 140 for temporary storage. The cleaning fluid in the receiving tank 140 is filtered by a filtration mechanism 800.

[0135] Immediately upon starting to clean the battery casing 10, cleaning fluid can be injected into the receiving tank 140 to provide cleaning fluid to the rinsing mechanism 300 and the spraying mechanism 400 through the filtering mechanism 800. Alternatively, the rinsing mechanism 300 and the spraying mechanism 400 can be connected to an external cleaning fluid to provide cleaning fluid to the rinsing mechanism 300 and the spraying mechanism 400.

[0136] In a specific implementation, the filtration mechanism 800 includes a filter element 810, a first pipeline 820 and at least one second pipeline 830. The first pipeline 820 connects the cleaning chamber 110 and the filter element 810, and the second pipeline 830 connects the filter element 810 and at least one of the rinsing mechanism 300 and the spraying mechanism 400. The filter element 810 is used to filter the cleaning liquid.

[0137] It is understood that the specific structure of the filter element 810 can be adapted to the type of cleaning fluid and actual needs, and this embodiment does not impose any restrictions here.

[0138] Specifically, the first pipeline 820 delivers the cleaning fluid in the receiving tank 140 to the filter element 810. After the filter element 810 filters the cleaning fluid, the cleaning fluid is delivered to the second pipeline 830, and then delivered to the rinsing mechanism 300 and the spraying mechanism 400 through the second pipeline 830.

[0139] In some embodiments, the filtration mechanism 800 further includes at least one liquid pump 840, which is disposed on at least one of the first conduit 820 and the second conduit 830.

[0140] The cleaning fluid in the receiving tank 140 is driven by the liquid pump 840 to flow to the filter element 810. At the same time, the liquid pump 840 can provide pressure to the cleaning fluid, so that the cleaning fluid delivered to the rinsing mechanism 300 and the spraying mechanism 400 has a certain pressure, thereby improving the cleaning effect of the rinsing mechanism 300 and the spraying mechanism 400, and also facilitating the formation of turbulence within the battery casing 10.

[0141] For example, the pressure range of the cleaning fluid delivered to the rinsing mechanism 300 and the spraying mechanism 400 by the liquid pump 840 can be 0.2MPa-2.0MPa.

[0142] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the fixing mechanism 200 includes at least one mounting assembly, which includes two first mounting beams 210 and a plurality of first limiting members 220. The first mounting beams 210 are connected to the support plate 120, and the space between the two first mounting beams 210 is used to accommodate the battery case 10. The arrangement direction of the two first mounting beams 210 is the same as the extension direction of the battery case 10. The first limiting members 220 are sequentially spaced on the first mounting beams 210, and the space between two adjacent first limiting members 220 is used to accommodate the battery case 10.

[0143] Specifically, a first limiting member 220 is provided to clamp the battery casing 10, thereby limiting the position of the battery casing 10. A first mounting beam 210 is provided to connect the first limiting member 220 and the support frame 100, so as to fix the first limiting member 220 on the support frame 100.

[0144] It is understood that the distance between two adjacent first limiting members 220 can be set according to the specific size of the battery case 10, and this embodiment does not impose any restrictions here.

[0145] For example, the first limiting member 220 is cylindrical to minimize the contact area between the first limiting member 220 and the battery casing 10, thereby increasing the area of ​​the battery casing 10 that can be cleaned and preventing the first limiting member 220 from affecting the cleaning effect of the battery casing 10. The hardness of the outer surface of the first limiting member 220 is less than the hardness of the battery casing 10 to prevent damage to the battery casing 10 when the first limiting member 220 contacts the battery casing 10.

[0146] In some examples, the first mounting beam 210 has at least one clearance groove 212 located between two adjacent first limiting members 220. The clearance groove 212 is used to avoid the battery case 10, so as to prevent the first mounting beam 210 from contacting the battery case 10 and affecting the cleaning effect of the battery case 10.

[0147] In a specific implementation, the mounting assembly also includes two second limiting members 230, which are connected to the first mounting beam 210. Each first limiting member 220 is located between the two second limiting members 230, and the second limiting members 230 are used to limit the battery case 10.

[0148] The battery casing 10 is located between two second limiting members 230 to limit the battery casing 10 and prevent it from falling between the two first limiting members 220.

[0149] For example, the extension direction of the first limiting member 220 is perpendicular to the extension direction of the second limiting member 230. The extension direction of the second limiting member 230 is the same as the extension direction of the first mounting beam 210.

[0150] Furthermore, the first mounting beam 210 has two connecting seats, which are connected to the second limiting member 230.

[0151] The second limiting member 230 is cylindrical to minimize the contact area between it and the battery casing 10, thereby increasing the area of ​​the battery casing 10 that can be cleaned and preventing it from affecting the cleaning effect. The hardness of the outer surface of the second limiting member 230 is less than the hardness of the battery casing 10 to prevent damage to the battery casing 10 when in contact.

[0152] In some embodiments, the fixing mechanism 200 further includes at least two second mounting beams 240 and at least one support member 250. The second mounting beams 240 connect the two second mounting beams 240 of the mounting assembly, and the support member 250 connects the two second mounting beams 240 and is located between the two second mounting beams 240 of the mounting assembly. The support member 250 is used to support the battery case 10.

[0153] The support member 250 abuts against the bottom of the battery casing 10 to support the battery casing 10. The two ends of the support member 250 are connected by a second mounting beam 240 to fix the support member 250.

[0154] For example, the support member 250 is cylindrical to minimize the contact area between the support member 250 and the battery casing 10, thereby increasing the area of ​​the battery casing 10 that can be cleaned and preventing the support member 250 from affecting the cleaning effect of the battery casing 10. The hardness of the outer surface of the support member 250 is less than the hardness of the battery casing 10 to prevent damage to the battery casing 10 when the support member 250 contacts the battery casing 10.

[0155] In some embodiments, the second mounting beam 240 has a plurality of mounting portions 241, which are arranged sequentially at intervals. The first mounting beam 210 has at least one mounting block 211, which is movable along the second mounting beam 240 to connect with any of the mounting portions 241.

[0156] The mounting block 211 is connected to different mounting parts 241 to adjust the distance between the two first mounting beams 210, thereby making the length range of the battery case 10 that can be accommodated between the two first mounting beams 210 wider and improving the applicability of the fixing mechanism 200.

[0157] For example, the second mounting beam 240 also has at least one limiting plate, and each mounting part 241 is arranged sequentially at intervals on the same side of the limiting plate. The mounting block 211 moves along the limiting plate and connects with one of the mounting parts 241.

[0158] Specifically, the mounting block 211 of one of the first mounting beams 210 can be fixed on the second mounting beam 240, and the distance between the two first mounting beams 210 can be adjusted by moving the other first mounting beam 210.

[0159] In a specific implementation, the cleaning device provided in this application embodiment also includes a third sealing mechanism 900. The upper part of the cleaning chamber 110 has a third opening 113. The third sealing mechanism 900 is used to close or open the third opening 113. When the third opening 113 is open, the fixing mechanism 200 can be installed in the cleaning chamber 110 through the third opening 113.

[0160] When cleaning the battery casing 10, the third opening 113 can be closed to prevent the cleaning fluid in the cleaning chamber 110 from splashing out or the mist from overflowing.

[0161] For example, after the third opening 113 is opened by the third closing mechanism 900, the fixing mechanism 200 containing the battery case 10 can be mounted on the support plate 120. Alternatively, the fixing mechanism 200 can be fixed on the support plate 120, and after the third opening 113 is opened, the battery cases 10 can be placed one by one on the fixing mechanism 200.

[0162] In some embodiments, the third closing mechanism 900 includes a cover plate 910 and a fourth drive member 920 connected to the cover plate 910. The fourth drive member 920 drives the cover plate 910 to move relative to the support frame 100 to open or close the third opening 113.

[0163] The third opening 113 is located on the upper side of the cleaning chamber 110. A fourth driving member 920 is provided to drive the cover plate 910 to open or close the third opening 113.

[0164] For example, the fourth drive unit 920 includes a drive chain and a control unit, which controls the movement of the drive chain, thereby driving the cover plate 910 to rise and fall relative to the support frame 100.
