Technical Field

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

[0002] Battery cells are widely used in electronic devices such as mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes, and power tools. Battery cells can include nickel-cadmium battery cells, nickel-metal hydride battery cells, lithium-ion battery cells, and rechargeable alkaline zinc-manganese battery cells, among others.

[0003] In the development of battery technology, how to reduce the manufacturing cost of individual battery cells is a technical problem that urgently needs to be solved. Utility Model Content

[0004] This application provides a battery cleaning device and a battery production apparatus, which aim to reduce the manufacturing cost of individual battery cells to a certain extent.

[0005] In a first aspect, this application proposes a battery cleaning device, which includes a cleaning mechanism, a cleaning medium feeding mechanism, and a recycling mechanism. The cleaning mechanism is used to clean battery cells and includes multiple cleaning components and multiple clamping components. Each cleaning component and each clamping component is correspondingly arranged. The multiple cleaning components are used to clean different areas of the outer surface of the battery cells. Each cleaning component includes a cleaning chamber and a spray plate. The cleaning chamber has an open cavity, and the spray plate is disposed in the cavity. The clamping components are used to clamp the battery cells and drive the battery cells to extend into the cavity through the opening. The cleaning medium feeding mechanism is connected to the spray plate and is used to provide cleaning medium and spray it through the spray plate. The recycling mechanism is connected to the cavity and is used to collect cleaning waste from the cleaning chamber.

[0006] The battery cleaning device provided in this application, through a cleaning mechanism and a cleaning medium feeding mechanism, sprays the cleaning medium provided by the cleaning medium feeding mechanism onto the outer surface of the battery cells via a spray nozzle. Under the impact of the high-pressure jet, the insulating adhesive and insulating film on the outer surface of the battery cells are rapidly peeled off, improving the recycling efficiency of battery cells, reducing the recycling cost of battery cells, promoting the recycling of waste battery cell resources, and thus reducing the manufacturing cost of battery cells. By setting up a cleaning chamber, the spray nozzle cleans the battery cells within the cleaning chamber, which can effectively limit the diffusion range of water mist during high-pressure water jet cleaning and reduce the spread of water mist to other functional areas. By setting up a recycling mechanism, the contamination of the cleaning mechanism by cleaning waste and secondary contamination of the battery cells are reduced. The battery cleaning device not only improves the cleaning efficiency of battery cells and reduces labor intensity, but also further improves the cleanliness and reliability of battery cells.

[0007] According to one embodiment of this application, the cleaning assembly further includes a delivery pipeline, at least a portion of which is located within a cavity. The delivery pipeline rotates relative to the cleaning chamber and moves along a first direction. A spray disc is disposed at one end of the delivery pipeline along the first direction. A delivery channel is provided within the delivery pipeline, communicating with the spray disc and a cleaning medium feeding mechanism. A clamping assembly is configured to move the battery cells along a second direction within the cavity, the first direction being perpendicular to the second direction. The delivery pipeline drives the spray disc to move along the first direction, thereby achieving precise adjustment of the target distance between the spray disc and the battery cells to adapt to the cleaning requirements of battery cells of different sizes. The clamping assembly is configured to move the battery cells along the second direction within the cavity, enabling the spray disc to rinse different areas of the battery cells during the cleaning process, effectively mitigating damage to the battery cells caused by localized force concentration and reducing the damage to the battery cell structure during the cleaning process.

[0008] According to one embodiment of this application, the cleaning assembly includes a first driving member and a second driving member; the first driving member is disposed outside the cleaning chamber and connected to the conveying pipeline, and is used to drive the conveying pipeline to rotate; the second driving member is disposed outside the cleaning chamber and connected to the conveying pipeline, and is used to drive the conveying pipeline to move along a first direction. The two driving members respectively realize the rotation of the spray disc and the adjustment of the target distance, which can not only adapt to battery cells of different sizes, but also improve the uniformity of cleaning.

[0009] According to one embodiment of this application, the cleaning assembly includes two spray discs arranged opposite each other along a first direction, and at least a portion of the clamping assembly moves between the two spray discs along a second direction. This achieves simultaneous cleaning of the battery cells on both sides in the first direction, improving cleaning efficiency and shortening the processing cycle of the battery cells. Furthermore, the impact forces on both sides are balanced, mitigating structural damage to the battery cells caused by concentrated force on one side.

[0010] According to one embodiment of this application, the cleaning assembly includes multiple spray disc units configured to be arranged along a second direction, with the spray discs of the multiple spray disc units having different diameters. The cleaning chamber is equipped with spray discs of different diameters, which can adapt to the cleaning needs of battery cells of different sizes, thereby effectively improving the applicability of the battery cleaning device.

[0011] According to one embodiment of this application, the clamping assembly includes a base, a robotic arm, and a clamping member. The robotic arm is movably mounted on the base; the clamping member is mounted on the robotic arm and is used to clamp individual battery cells and drive the battery cells to move relative to the cleaning assembly. The robotic arm is movably mounted on the base to allow the clamping member to flexibly adjust the position and orientation of the battery cells, thereby effectively adapting to the cleaning range of the spray nozzle. The clamping member can stably clamp the battery cells, reducing the risk of battery cells shifting, shaking, or getting stuck.

[0012] According to one embodiment of this application, the clamping component includes a support frame, two connecting rods, and a third driving member; the support frame is connected to a robotic arm; the two connecting rods are arranged opposite to each other and rotatably mounted on the support frame; the third driving member is disposed on the support frame and connected to the two connecting rods, and is used to drive the two connecting rods to rotate to clamp the battery cell. By driving the two connecting rods to rotate through the third driving member, the clamping distance can be adjusted, flexibly adapting to battery cells of different sizes and improving the applicability of the battery cleaning device.

[0013] According to one embodiment of this application, the connecting rod includes a rotating part and a clamping part. The rotating part is rotatably mounted on a support frame, one end of the rotating part is connected to a third driving member, and the other end of the rotating part is connected to the clamping part, which is used to clamp a single battery cell. This simplifies the structure of the connecting rod and reduces the overall space occupied by the connecting rod.

[0014] According to one embodiment of this application, the clamping member further includes a seal, which is disposed on the support frame and at least a portion of the seal is located between the two connecting rods. The seal is used to seal the electrode terminals of the battery cell. By providing the seal, the electrode terminals of the battery cell are protected during the cleaning process, effectively preventing contact between the cleaning medium and the electrode terminals.

[0015] According to one embodiment of this application, the cleaning mechanism further includes a feeding component, a transfer component, and a receiving component; the feeding component is used to provide battery cells; the transfer component is located downstream of the feeding component and is used to transfer the battery cells provided by the feeding component; the receiving component is located downstream of the transfer component and is used to receive the battery cells transferred by the transfer component; and a clamping component is used to clamp the battery cells received by the receiving component. This configuration enables precise transfer of battery cells to the receiving component.

[0016] According to one embodiment of this application, the transfer component includes a gripper, a fourth drive component, and a fifth drive component. The gripper is used to grip the battery cells provided by the feeding component. The fourth drive component is connected to the gripper and is used to drive the gripper to move along a third direction. The fifth drive component is connected to the fourth drive component and is used to drive the fourth drive component and drive the gripper to move along a second direction, which is perpendicular to the third direction. The fourth and fifth drive components adjust the battery cells in two directions through the gripper, so that the battery cells can be accurately positioned at the centering position of the receiving component, so that the subsequent clamping component can smoothly clamp the battery cells into the cleaning chamber and place the battery cells at a preset target distance position.

[0017] According to one embodiment of this application, the receiving component includes a receiving platform and a sixth driving member; the receiving platform is used to receive the battery cell transferred by the transfer component; the sixth driving member is used to drive the receiving platform to move along a first direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other. This reduces the frequency of position adjustment after the clamping component clamps the battery cell, thereby enabling the battery cell to be accurately positioned at a preset target distance, improving the stability and efficiency of target distance positioning.

[0018] According to one embodiment of this application, the feeding assembly includes a conveyor belt, two guide members, and a seventh drive member. The conveyor belt is used to transport battery cells; the two guide members are disposed on both sides of the conveyor belt along a first direction, the first direction being perpendicular to the conveying direction of the conveyor belt; the seventh drive member is used to drive the guide members to move along the first direction. The two guide members form a limiting guide channel, which can limit the movement trajectory of the battery cells on the conveyor belt and reduce the risk of displacement or slippage during the conveying process. By driving the relative movement of the two guide members by the seventh drive member, the spacing between the guide members can be flexibly adjusted to accommodate battery cells of different sizes and specifications.

[0019] According to one embodiment of this application, the cleaning mechanism further includes a temporary storage component, which is disposed between two adjacent cleaning components. The temporary storage component is used to receive the battery cells cleaned by the upstream cleaning component and drive the battery cells to move along a first direction, which is perpendicular to the arrangement direction of the two adjacent cleaning components. Placing the battery cells in the temporary storage component facilitates clamping by the clamping component of the downstream cleaning component. The clamping component of the downstream cleaning component can smoothly clamp the battery cells into the cleaning chamber and position the battery cells at a preset target distance.

[0020] According to one embodiment of this application, the cleaning medium feeding mechanism includes a cleaning medium pipeline, a pressurizing pump, and a pressure detection device. The cleaning medium pipeline is connected to the spray nozzle and is used to transport the cleaning medium. The pressurizing pump is disposed in the cleaning medium pipeline and is used to pressurize the cleaning medium. The pressure detection device is disposed in the cleaning medium pipeline, downstream of the pressurizing pump, and is used to detect the pressure of the cleaning medium in the cleaning medium pipeline. By monitoring the pressure of the cleaning medium in real time through the pressure detection device, the spray nozzle can be adjusted to stably spray the cleaning medium within a preset pressure range. This also reduces the impact damage to the battery cells caused by abnormal cleaning medium pressure, thereby protecting the battery cells.

[0021] Secondly, this application proposes a battery production apparatus, which includes the aforementioned battery cleaning apparatus. The battery cleaning apparatus is used to remove the insulating film attached to the outer surface of the battery cell; or, the battery cleaning apparatus is used to remove the insulating adhesive attached to the outer surface of the battery cell; or, the battery cleaning apparatus is used to remove both the insulating film and the insulating adhesive attached to the outer surface of the battery cell.

[0042] Currently, judging from market trends, the application of batteries is becoming increasingly widespread. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace, among other fields.

[0043] With the rapid development of the battery industry, battery devices have entered a large-scale retirement cycle. Although most of the battery cells inside have experienced capacity decay, they still meet the needs of secondary use scenarios. Even among batteries with individual failed cells, the remaining cells still possess high recycling value. Disassembling and recycling these cells can help reduce manufacturing costs. However, disassembled battery cells suffer from problems such as damaged insulating films and residual high-strength insulating adhesive at the bottom, making them unsuitable for direct reuse and posing risks such as short circuits and leakage. Due to the high peel strength of the insulating film and the strong adhesion of the insulating adhesive, manual handling by operators is time-consuming, labor-intensive, and inefficient. The above statements are only for providing background information related to this application and do not necessarily constitute prior art.

[0044] The battery cleaning device provided in this application, through a cleaning mechanism and a cleaning medium feeding mechanism, sprays the cleaning medium provided by the cleaning medium feeding mechanism onto the outer surface of the battery cells via a spray nozzle. Under the impact of the high-pressure jet, the insulating adhesive and insulating film on the outer surface of the battery cells are rapidly peeled off, improving the recycling efficiency of battery cells, reducing the recycling cost of battery cells, promoting the recycling of waste battery cell resources, and thus reducing the manufacturing cost of battery cells. By setting up a cleaning chamber, the spray nozzle cleans the battery cells within the cleaning chamber, which can effectively limit the diffusion range of water mist during high-pressure water jet cleaning and reduce the spread of water mist to other functional areas. By setting up a recycling mechanism, the contamination of the cleaning mechanism by cleaning waste and secondary contamination of the battery cells are reduced. The battery cleaning device not only improves the cleaning efficiency of battery cells and reduces labor intensity, but also further improves the cleanliness and reliability of battery cells.

[0045] For ease of explanation, the following embodiments use a battery cleaning device according to an embodiment of this application as an example.

[0046] See Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a battery cleaning device provided in an embodiment of this application; Figure 2 This is a schematic diagram of the cleaning mechanism of a battery cleaning device provided in an embodiment of this application; Figure 3 This is a schematic diagram of the cleaning component of a battery cleaning device provided in an embodiment of this application.

[0047] Firstly, such as Figures 1 to 3As shown, this application proposes a battery cleaning device, which includes a cleaning mechanism 10 and a cleaning medium feeding mechanism 20. The cleaning mechanism 10 is used to clean the outer surface of a battery cell 100. The cleaning mechanism 10 includes multiple cleaning components 11 and multiple clamping components 12, with each cleaning component 11 and each clamping component 12 correspondingly arranged. The multiple cleaning components 11 are used to clean different areas of the outer surface of the battery cell 100. Each cleaning component 11 includes a cleaning chamber 111 and a spray disc 112. The cleaning chamber 111 has a cavity 1112 with an opening 1111. The spray disc 112 is disposed within the cavity 1112. The clamping components 12 are used to clamp the battery cell 100 and drive the battery cell 100 to extend into the cavity 1112 through the opening 1111. The cleaning medium feeding mechanism 20 is connected to the spray disc 112 and is used to provide cleaning medium and spray it through the spray disc 112.

[0048] The battery cell 100 includes a housing, which includes an outer peripheral surface. The cleaning mechanism 10 is used to clean the outer surface of the battery cell 100 to remove the insulating film and insulating adhesive attached to the outer surface.

[0049] In some examples, the cleaning chamber 111 may be a hollow structure with an opening on one side; or, the cleaning chamber 111 may be a hollow structure with openings on both sides.

[0050] In some examples, the cleaning chamber 111 can be of various shapes, such as cylinder, cuboid, etc.

[0051] The cleaning chamber 111 can be made of various materials, such as steel, aluminum alloy, or other composite materials. One option is carbon fiber composite material, which has the advantages of being lightweight, high-strength, and impact-resistant.

[0052] In some examples, the cleaning chamber 111 includes two first walls disposed opposite each other along a first direction x, two second walls disposed opposite each other along a second direction y, and a bottom wall connected to the two first walls and the two second walls, the first walls being connected to the two second walls, and an opening 1111 disposed opposite to the bottom wall.

[0053] In some examples, the bottom wall is curved or conical.

[0054] In some examples, the spray disc 112 includes a disc body and a plurality of nozzles. The disc body has a cavity communicating with the plurality of nozzles, which are disposed within the disc body. The cavity is used for the flow of cleaning media.

[0055] During the cleaning process of the battery cell 100, the cleaning medium is evenly sprayed onto a specific area of ​​the battery cell 100 through the spray nozzle 112.

[0056] Optionally, the material can be sprayed onto the outer surface of the battery cell 100 to remove the insulating film and insulating adhesive adhering to the outer surface.

[0057] For example, the cleaning assembly 11 includes two spray discs 112 disposed opposite to each other. At least a portion of the battery cell 100 held by the clamping assembly 12 is located between the two spray discs 112.

[0058] Optionally, the two spray nozzles 112 are configured to clean the two large surfaces of the battery cell 100.

[0059] In some examples, the cleaning assembly 11 includes multiple spray discs 112, each with a different diameter.

[0060] In some examples, the cleaning medium feeding mechanism 20 may be directly connected to the spray disc 112; alternatively, the cleaning medium feeding mechanism 20 may be connected to the spray disc 112 via other components, such as pipes.

[0061] In some embodiments, the cleaning medium may be one of water, ethanol, or acetone.

[0062] Optionally, the cleaning medium is water.

[0063] The battery cleaning device includes a recycling mechanism 30. The recycling mechanism 30 is connected to the cavity 1112 and is used to collect cleaning waste inside the cleaning chamber 111.

[0064] In some examples, the recycling mechanism 30 includes a recycling pipeline and a filter assembly. The recycling pipeline is connected to the cavity 1112 of the cleaning chamber 111, and the filter assembly is connected to the recycling pipeline. The filter assembly is used to filter cleaning waste. The recycling pipeline recycles the cleaning waste after the cleaning medium has cleaned the battery cells 100, and the filter assembly is used to filter the cleaning waste.

[0065] Specifically, the cleaning waste includes the cleaning medium and the insulating adhesive and insulating film rinsed from the battery cell 100 by the cleaning medium.

[0066] For example, the recovery mechanism 30 also includes a circulation pipeline connected to the filter assembly and the spray plate 112. The filter assembly achieves solid-liquid separation and is used to transport the recovered and filtered cleaning medium to the spray plate 112, thereby enabling the recycling of the cleaning medium.

[0067] For example, the battery cell 100 includes two first surfaces opposite each other along a first direction x, two second surfaces opposite each other along a second direction y, and a top surface and a bottom surface opposite each other along a third direction z. The cleaning mechanism 10 includes three cleaning components 11: one cleaning component 11 for cleaning the two first surfaces of the battery cell 100, one cleaning component 11 for cleaning the two second surfaces of the battery cell 100, and one cleaning component 11 for cleaning the bottom surface of the battery cell 100. By employing multiple cleaning components 11 for zoned targeted cleaning, each cleaning component 11 cleans a different area of ​​the outer surface of the battery cell 100, improving cleaning quality and reliability.

[0068] The battery cleaning device provided in this application, through a cleaning mechanism 10 and a cleaning medium feeding mechanism 20, sprays the cleaning medium provided by the cleaning medium feeding mechanism 20 onto the outer surface of the battery cell 100 via a spray nozzle 112. Under the impact of the high-pressure jet, the insulating adhesive and insulating film on the outer surface of the battery cell 100 are rapidly peeled off, improving the recycling efficiency of the battery cell 100, reducing the recycling cost of the battery cell 100, promoting the recycling of waste battery cell 100 resources, and thus reducing the manufacturing cost of the battery cell. By setting up a cleaning chamber 111, the spray nozzle 112 cleans the battery cell 100 within the cleaning chamber 111, which effectively limits the diffusion range of water mist during the high-pressure water jet cleaning process and reduces the spread of water mist to other functional areas. By setting up a recycling mechanism 30, the contamination of the cleaning mechanism 10 by cleaning waste and secondary contamination of the battery cell 100 are reduced. The battery cleaning device not only improves the cleaning efficiency of the battery cell 100 and reduces labor intensity, but also further improves the cleanliness and reliability of the battery cell 100.

[0069] According to one embodiment of this application, such as Figure 3 As shown, the cleaning assembly 11 also includes a delivery pipe 13, at least a portion of which is located within the cavity 1112. The delivery pipe 13 rotates relative to the cleaning chamber 111 and moves along a first direction x. A spray disc 112 is disposed at one end of the delivery pipe 13 along the first direction x. A delivery channel is provided within the delivery pipe 13, which communicates with the spray disc 112 and the cleaning medium feeding mechanism 20. The clamping assembly 12 is configured to drive the battery cell 100 to move along a second direction y within the cavity 1112, where the first direction x is perpendicular to the second direction y.

[0070] In some examples, the delivery pipeline 13 includes a first pipeline and a second pipeline. The first pipeline is movably disposed in the cleaning chamber 111 and located within the cavity 1112. The first pipeline is connected to the second pipeline and the spray disc 112. The second pipeline is disposed outside the cleaning chamber 111 and is connected to the cleaning medium feeding mechanism 20.

[0071] For example, the cleaning assembly 11 also includes a drive member for driving the delivery line 13 and causing the spray disc 112 to rotate and move along the first direction x.

[0072] In these alternative embodiments, the delivery conduit 13 drives the spray disc 112 to move along the first direction x, thereby achieving precise adjustment of the target distance between the spray disc 112 and the battery cell 100 to adapt to the cleaning needs of battery cells 100 of different sizes. The clamping assembly 12 is configured to drive the battery cell 100 to move along the second direction y within the cavity 1112. During the cleaning process, the spray disc 112 can rinse different areas of the battery cell 100, effectively improving the damage to the battery cell 100 caused by localized force concentration and reducing the damage to the structure of the battery cell 100 during the cleaning process.

[0073] According to one embodiment of this application, such as Figure 3 As shown, the cleaning assembly 11 includes a first driving member 14 and a second driving member 15. The first driving member 14 is disposed on the outside of the cleaning chamber 111 and connected to the conveying pipeline 13, and is used to drive the conveying pipeline 13 to rotate. The second driving member 15 is disposed on the outside of the cleaning chamber 111 and connected to the conveying pipeline 13, and is used to drive the conveying pipeline 13 to move along a first direction x.

[0074] Based on the size of the battery cell 100, the first drive member 14 drives the conveying pipe 13 to move the spray plate 112 to a predetermined position. The first drive member 14 stops driving, and the cleaning medium feeding mechanism 20 provides cleaning medium to the spray plate 112 through the conveying pipe 13. The first drive member 14 drives the conveying pipe 13 to rotate the spray plate 112, and the cleaning medium is sprayed from the spray plate 112 onto the battery cell 100.

[0075] For example, the first driving component 14 includes a rotary motor, which is connected to the delivery pipe 13 and drives the delivery pipe 13 to rotate the spray disc 112.

[0076] For example, the second drive unit 15 includes a target distance adjustment motor and a lead screw, the lead screw being connected to a rotary motor and a conveying pipeline 13, the lead screw driving the conveying pipeline 13 to move along a first direction x.

[0077] In some examples, the cleaning assembly 11 also includes a frame, on which the first drive 14, the second drive 15 and the cleaning chamber 111 are all disposed.

[0078] In these alternative embodiments, the two drive components respectively realize the rotation of the spray disc 112 and the target distance adjustment, which can not only adapt to battery cells 100 of different sizes, but also improve the uniformity of cleaning.

[0079] According to one embodiment of this application, such as Figure 3As shown, the cleaning assembly 11 includes two spray discs 112, which are arranged opposite each other along a first direction x, and at least a portion of the clamping assembly 12 moves between the two spray discs 112 along a second direction y.

[0080] In some examples, the clamping assembly 12 is configured to clamp the battery cell 100 and move it at a constant speed along a second direction y between two spray discs 112. This allows for rinsing of both sides of the battery cell 100, improving rinsing efficiency.

[0081] In some examples, the cleaning assembly 11 includes a first spray disc, a second spray disc, a first delivery pipe, and a second delivery pipe. The first and second spray discs are arranged opposite each other along a first direction x. The first delivery pipe is connected to the first spray disc, and the second delivery pipe is connected to the second spray disc. This allows for simultaneous cleaning of both surfaces of the battery cell 100, accelerating the removal rate of insulating adhesive and insulating film.

[0082] For example, the battery cell 100 has two opposing first surfaces along a first direction x and two opposing second surfaces along a second direction y. The clamping assembly 12 clamps the two second surfaces, and two spray discs 112 are respectively disposed opposite to the two first surfaces.

[0083] In these alternative embodiments, the battery cell 100 is simultaneously cleaned on both sides in the first direction x, improving cleaning efficiency and shortening the processing cycle of the battery cell 100. Moreover, the impact forces on both sides are balanced, mitigating structural damage to the battery cell 100 caused by concentrated force on one side.

[0084] According to one embodiment of this application, such as Figure 3 As shown, the cleaning assembly 11 includes a plurality of spray disc units 112a, which are configured to be arranged along the second direction y, and the diameters of the spray discs 112 of the plurality of spray disc units 112a are different.

[0085] For example, the cleaning assembly 11 includes a first spray disc unit and a second spray disc unit, the first spray disc unit and the second spray disc unit are arranged along the second direction y, the two spray discs 112 of the first spray disc unit are arranged opposite each other along the first direction x, the two spray discs 112 of the second spray disc unit are arranged opposite each other along the first direction x, and the diameter of the spray disc 112 of the first spray disc unit is larger than the diameter of the spray disc 112 of the second spray disc unit.

[0086] In these alternative embodiments, the cleaning chamber 111 is equipped with spray discs 112 of different diameters, which can adapt to the cleaning needs of battery cells 100 of different specifications, thereby effectively improving the applicability of the battery cleaning device.

[0087] See also Figure 4 , Figure 4This is a partial structural schematic diagram of the clamping assembly of a battery cleaning device provided in one embodiment of this application.

[0088] According to one embodiment of this application, such as Figure 2 and Figure 4 As shown, the clamping assembly 12 includes a base 121, a robotic arm 122, and a clamping member 123; the robotic arm 122 is movably disposed on the base 121; the clamping member 123 is disposed on the robotic arm 122, and the clamping member 123 is used to clamp the battery cell 100 and drive the battery cell 100 to move relative to the cleaning assembly 11.

[0089] The battery cell 100 is clamped by the clamping assembly 12 and moved along the second direction y within the cavity 1112. Compared to using a conveyor belt 161 to drive the battery cell 100 along the second direction y within the cavity 1112, the latter is prone to unstable movement speed or jamming of the battery cell 100 due to friction fluctuations or the falling of insulating film, insulating adhesive, etc., from the battery cell 100 onto the surface of the conveyor belt 161, which can lead to battery cell 100 breakdown or structural damage. The clamping assembly 12 clamps the battery cell 100, which can effectively improve the defects of unstable movement speed or jamming of the battery cell 100 and improve the smoothness and reliability of the movement process of the battery cell 100.

[0090] For example, the battery cell 100 includes two first surfaces opposite each other along a first direction x, two second surfaces opposite each other along a second direction y, and a top surface and a bottom surface opposite each other along a third direction z.

[0091] When the clamping member 123 clamps the two second surfaces, the two spray discs 112 are respectively arranged opposite to the two first surfaces; or, the spray discs 112 are arranged opposite to the bottom surface.

[0092] When the clamping member 123 clamps the two first surfaces, the two spray discs 112 are respectively arranged opposite to the two second surfaces; or, the spray discs 112 are arranged opposite to the bottom surface.

[0093] In some examples, the robotic arm 122 drives the gripper 123 to move relative to the base 121 along a first direction x, a second direction y, and a third direction z.

[0094] In these alternative embodiments, the robotic arm 122 is movably mounted on the base 121 to drive the gripper 123 to flexibly adjust the position and orientation of the battery cell 100, thereby effectively adapting to the cleaning range of the spray nozzle 112. The gripper 123 can stably hold the battery cell 100, reducing the risk of displacement, shaking, or jamming of the battery cell 100.

[0095] According to one embodiment of this application, such as Figure 2 and Figure 4As shown, the clamping member 123 includes a support frame 1231, two connecting rods 1232, and a third driving member 1233. The support frame 1231 is connected to the robotic arm 122. The two connecting rods 1232 are arranged opposite to each other and are rotatably mounted on the support frame 1231. The third driving member 1233 is mounted on the support frame 1231 and connected to the two connecting rods 1232, and is used to drive the two connecting rods 1232 to rotate in order to clamp the battery cell 100.

[0096] In some examples, the third drive element 1233 includes a telescopic cylinder.

[0097] For example, during the transition from the retracted state to the extended state of the telescopic cylinder, two connecting rods 1232 are rotated, with at least portions of the two connecting rods 1232 moving away from each other to release the battery cell 100. During the transition from the extended state to the retracted state of the telescopic cylinder, two connecting rods 1232 are rotated, with at least portions of the two connecting rods 1232 moving closer to each other to clamp the battery cell 100.

[0098] In some examples, two links 1232 are used to clamp the two opposite outer surfaces of the battery cell 100.

[0099] In these alternative embodiments, the clamping distance can be adjusted by driving the two connecting rods 1232 to rotate via the third driving member 1233, which can flexibly adapt to battery cells 100 of different sizes and improve the applicability of the battery cleaning device.

[0100] According to one embodiment of this application, such as Figure 2 and Figure 4 As shown, the connecting rod 1232 includes a rotating part 12321 and a clamping part 12322. The rotating part 12321 is rotatably mounted on the support frame 1231. One end of the rotating part 12321 is connected to the telescopic cylinder, and the other end of the rotating part 12321 is connected to the clamping part 12322. The clamping part 12322 is used to clamp the battery cell 100.

[0101] In some examples, the rotating part 12321 and the clamping part 12322 are arranged vertically. The vertical arrangement of the rotating part 12321 and the clamping part 12322 effectively saves the layout space of both, thereby reducing the overall space occupied by the connecting rod 1232.

[0102] In some examples, the end of the rotating part 12321 near the clamping part 12322 is connected to the support frame 1231 pin.

[0103] In these alternative embodiments, the structure of link 1232 is simplified, and the overall space occupied by link 1232 is reduced.

[0104] According to one embodiment of this application, such as Figure 2 and Figure 4As shown, the clamping member 123 also includes a sealing member 1234, which is disposed on the support frame 1231. At least a portion of the sealing member 1234 is located between the two connecting rods 1232, and the sealing member 1234 seals the electrode terminal 101 of the battery cell 100.

[0105] In some examples, the seal 1234 is provided with a cavity having an opening 1111. One end of the seal 1234 forming the opening 1111 is used to abut against the battery cell 100. That is, during the cleaning process of the battery cell 100, the opening 1111 of the seal 1234 abuts against the battery cell 100.

[0106] In these alternative embodiments, by providing a seal 1234, the electrode terminals 101 of the battery cell 100 are protected during the cleaning process, effectively preventing the cleaning medium from contacting the electrode terminals 101.

[0107] See also Figure 5 , Figure 5 This is a partial structural schematic diagram of the cleaning mechanism of a battery cleaning device provided in an embodiment of this application.

[0108] According to one embodiment of this application, such as Figure 1 , Figure 2 and Figure 5 As shown, the cleaning mechanism 10 also includes a feeding assembly 16, a transfer assembly 17, and a receiving assembly 18. The feeding assembly 16 is used to provide battery cells 100. The transfer assembly 17 is located downstream of the feeding assembly 16 and is used to transfer the battery cells 100 provided by the feeding assembly 16. The receiving assembly 18 is located downstream of the transfer assembly 17 and is used to receive the battery cells 100 transferred by the transfer assembly 17. The clamping assembly 12 is used to clamp the battery cells 100 received by the receiving assembly 18.

[0109] The feeding assembly 16 may include multiple transmission channels, which can transport multiple battery cells 100 separately. The transmission paths of each transmission channel may be the same or different to achieve synchronous transport of multiple battery cells 100, thereby accelerating the transport of battery cells 100.

[0110] For example, the feeding assembly 16 may include gear drive, chain drive, belt drive, shaft drive, etc.

[0111] In some examples, along the second direction y, the transfer component 17 is located between the feeding component 16 and the receiving component 18.

[0112] Optionally, the transfer component 17 can reciprocate between the feeding component 16 and the receiving component 18 to transfer the battery cell 100 and transfer the battery cell 100 onto the receiving component 18.

[0113] For example, the transfer assembly 17 may be a hoisting assembly to hoist the battery cell 100 onto the receiving assembly 18.

[0114] For example, the transfer component 17 may be a pushing component to push the battery cell 100 onto the receiving component 18.

[0115] In these alternative embodiments, this configuration enables precise transfer of the battery cell 100 to the receiving assembly 18.

[0116] According to one embodiment of this application, such as Figure 2 and Figure 5 As shown, the transfer assembly 17 includes a gripper 171, a fourth drive member 172, and a fifth drive member 173. The gripper 171 is used to grip the battery cell 100 provided by the loading assembly 16. The fourth drive member 172 is connected to the gripper 171 and is used to drive the gripper 171 to move along a third direction z. The fifth drive member 173 is connected to the fourth drive member 172 and is used to drive the fourth drive member 172 and drive the gripper 171 to move along a second direction y, which is perpendicular to the third direction z.

[0117] In these optional embodiments, the fourth drive member 172 and the fifth drive member 173 adjust the battery cell 100 in two directions through the gripper 171, so that the battery cell 100 can be accurately positioned at the centering position of the receiving component 18, so that the subsequent clamping component 12 can smoothly clamp the battery cell 100 into the cleaning chamber 111 and place the battery cell 100 at the preset target distance position.

[0118] According to one embodiment of this application, the receiving assembly 18 includes a receiving platform 181 and a sixth driving member 182. The receiving platform 181 is used to receive the battery cell 100 transferred by the transfer assembly 17. The sixth driving member 182 is used to drive the receiving platform 181 to move along a first direction x, wherein the first direction x, the second direction y, and the third direction z are perpendicular to each other.

[0119] In these alternative embodiments, the frequent adjustment of the position of the battery cell 100 after the clamping assembly 12 clamps it is reduced, thereby enabling the battery cell 100 to be accurately positioned at the preset target distance, improving the stability and efficiency of target distance positioning.

[0120] According to one embodiment of this application, such as Figure 2 and Figure 5As shown, the feeding assembly 16 includes a conveyor belt 161, two guide members 162, and a seventh drive member 163. The conveyor belt 161 is used to transport battery cells 100. The two guide members 162 are disposed on both sides of the conveyor belt 161 along a first direction x, which is perpendicular to the transport direction of the conveyor belt 161. The seventh drive member 163 is used to drive the guide members 162 to move along the first direction x.

[0121] In some examples, a seventh drive 163 is used to drive two guides 162 to move relative to each other along a first direction x. This adjusts the gap between the two guides 162 to accommodate battery cells 100 of different sizes.

[0122] In some examples, guide 162 includes a baffle and a roller, with the roller rotatably mounted on the baffle. The low frictional resistance between the roller and the battery cell 100 effectively facilitates the smooth transport of the battery cell 100, reducing the risk of scratches or displacement of the battery cell 100 surface due to excessive friction during transport.

[0123] For example, the baffle extends along the transmission direction.

[0124] For example, guide 162 includes a plurality of rollers arranged along the transport direction.

[0125] In these optional embodiments, the two side guide members 162 form a limiting guide channel, which can limit the movement trajectory of the battery cell 100 on the conveyor belt 161 and reduce the risk of displacement or slippage during the conveying process. The relative movement of the two side guide members 162 is driven by the seventh drive member 163, and the distance between the guide members 162 can be flexibly adjusted to accommodate battery cells 100 of different sizes and specifications.

[0126] According to one embodiment of this application, such as Figure 1 As shown, the cleaning mechanism 10 also includes a temporary storage component 19, which is disposed between two adjacent cleaning components 11. The temporary storage component 19 is used to receive the battery cell 100 cleaned by the upstream cleaning component 11 and drive the battery cell 100 to move along the first direction x, which is perpendicular to the arrangement direction of the two adjacent cleaning components 11.

[0127] In these optional embodiments, the battery cell 100 is placed in the temporary storage component 19, which facilitates clamping by the clamping component 12 of the downstream cleaning component 11. The clamping component 12 of the downstream cleaning component 11 can smoothly clamp the battery cell 100 into the cleaning chamber 111, and enable the battery cell 100 to be positioned at a preset target distance.

[0129] According to one embodiment of this application, such as Figure 6 As shown, the cleaning mechanism 10 also includes a feeding assembly 40, which includes a conveyor belt 41, two limiting members 42, and an eighth driving member 43. The conveyor belt 41 is used to transport the battery cells 100. The two limiting members 42 are disposed on both sides of the conveyor belt 41 along a first direction x, which is perpendicular to the transmission direction of the conveyor belt 41. The eighth driving member 43 is used to drive the limiting members 42 to move along the first direction x.

[0130] In some examples, the unloading assembly 40 also includes a positioning carrier 44 and a push rod 45. The positioning carrier 44 is located upstream of the conveyor belt 41 and is used to receive the battery cells 100 cleaned by the cleaning mechanism 10. The push rod 45 moves along the second direction y to push the battery cells 100 on the positioning carrier 44 onto the conveyor belt 41.

[0131] See also Figure 7 , Figure 7 This is a schematic diagram of the cleaning medium feeding mechanism of a battery cleaning device provided in an embodiment of this application.

[0132] According to one embodiment of this application, such as Figure 1 and Figure 7 As shown, the cleaning medium feeding mechanism 20 includes a cleaning medium pipeline 21, a pressurizing pump 22, and a pressure detection element 23. The cleaning medium pipeline 21 is connected to the spray disc 112 and is used to transport the cleaning medium. The pressurizing pump 22 is located in the cleaning medium pipeline 21 and is used to pressurize the cleaning medium. The pressure detection element 23 is located in the cleaning medium pipeline 21, downstream of the pressurizing pump 22, and is used to detect the pressure of the cleaning medium in the cleaning medium pipeline 21.

[0133] Based on the size of the battery cell 100, a predetermined pressure of the cleaning medium is set. When the pressure of the cleaning medium in the cleaning medium pipeline 21 is detected by the pressure detection element 23 as exceeding the predetermined pressure range, the supply of cleaning medium to the spray nozzle 112 is suspended to protect the battery cell 100.

[0134] In some examples, the pressure of the cleaning medium in the cleaning medium line 21 is greater than or equal to 2 MPa.

[0135] In some examples, the cleaning medium feeding mechanism 20 also includes a filter 24, which is connected to the cleaning medium line 21 and located upstream of the pressure pump 22. The filter 24 is used to filter the cleaning medium.

[0136] In these optional embodiments, the pressure of the cleaning medium is monitored in real time by the pressure detection element 23, and the spray disc 112 is adjusted to spray the cleaning medium stably within the preset pressure range. This can also reduce the impact damage to the battery cell 100 caused by abnormal pressure of the cleaning medium, thereby protecting the battery cell 100.
