[0075] As described in the background section, the cleaning equipment in the aforementioned related technologies suffers from problems such as low cleaning efficiency and unstable quality, making it difficult to meet the needs of large-scale production.

[0076] The reason for this problem lies in the long-standing dilemma of balancing efficiency and quality in the field of aluminum-plastic film cleaning, under current technology. Traditional single-station cleaning devices require manual intervention in multiple operation steps, resulting in poor production continuity. On the other hand, multi-stage cleaning processes often rely on multiple devices arranged in series, leading to low space utilization. A lithium battery packaging workshop once tried to use conveyor belt cleaning equipment to process aluminum-plastic film, but due to waiting time between cleaning stations and the separation of the drying and cleaning processes, the overall processing cycle was prolonged, and the cleaned film material was susceptible to secondary contamination during transportation.

[0077] To address the aforementioned problems, this application provides a cleaning device. The cleaning mechanism integrates multiple ultrasonic cleaning tanks arranged along a first direction on a support frame. The cleaning device can transport the parts to be cleaned at each station according to the arrangement of the ultrasonic cleaning tanks via a transport mechanism, enabling multi-round cleaning of the parts. This avoids back-and-forth transport between multiple independently set cleaning tanks, eliminates waiting time between processes, increases throughput per unit time, and improves cleaning efficiency. Using ultrasonic cleaning tanks for cleaning parts reduces surface impurities and improves cleaning quality compared to existing spray cleaning methods. The transport mechanism saves labor and improves transport efficiency. The drying mechanism is positioned adjacent to the last ultrasonic cleaning tank, shortening the transfer distance of the cleaned parts and reducing moisture evaporation time.

[0078] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0079] refer to Figure 1 and Figure 2 This application provides a cleaning device, which may include a support 100, a cleaning mechanism 200, a drying mechanism 300, and a conveying mechanism 400.

[0080] The support 100 has a first direction (e.g.) Figure 1The loading section 110 and unloading section 120 are opposite each other in one direction. The loading section 110 is used to hold unwashed cleaning parts. In some embodiments, the loading section 110 may have a parking area where operators transport unwashed cleaning parts to the loading section 110 via trolleys. The unloading section 120 may also have a parking area where cleaned and dried parts are placed on trolleys in the parking area of ​​the unloading section 120, and operators can transport the cleaned and dried parts to other workshops via trolleys. In addition to parking trolleys, the parking areas of the loading section 110 and unloading section 120 can also be replaced with conveyor belt devices to facilitate the connection of the cleaning equipment with other processes via conveyor belt devices.

[0081] The first direction can be the length direction of the support 100, forming the main axis of material handling. The support 100 can refer to the main frame supporting each functional module, specifically implemented as a continuous support platform formed by welding steel structures. This frame divides the material handling area along its length. It is understood that the cleaning components can be aluminum-plastic film used for batteries or other parts that can be cleaned ultrasonically. The loading section 110 can refer to a station for holding uncleaned cleaning components transported from other processes to the cleaning equipment. The unloading section 120 can refer to a station for holding clean cleaning components that have been cleaned and dried by the cleaning equipment. The loading section 110 can be the beginning of the cleaning equipment, and the unloading section 120 can be the end of the cleaning equipment.

[0082] The cleaning mechanism 200 may include multiple ultrasonic cleaning tanks arranged along a first direction from the loading section 110 to the unloading section 120, all mounted on the support 100. Each ultrasonic cleaning tank is used to sequentially clean the parts. The ultrasonic cleaning tanks in the cleaning mechanism 200 can refer to workstations with independent cleaning functions, specifically implemented using stainless steel tanks and ultrasonic transducers. Multiple tanks are arranged sequentially along the direction of movement of the parts to be cleaned, forming a cleaning channel. Each ultrasonic cleaning tank contains a cleaning solution for cleaning the parts. The parameters of the cleaning solution in each ultrasonic cleaning tank can be individually configured according to cleaning needs.

[0083] In some embodiments, the multiple ultrasonic cleaning tanks may include two, three, or more. When there are three ultrasonic cleaning tanks, they can sequentially perform rough cleaning, fine cleaning, and rinsing on the parts to be cleaned, along the direction from the loading end to the unloading end. The ultrasonic cleaning tanks in the cleaning mechanism 200 are arranged in the process sequence of rough cleaning, fine cleaning, and rinsing, and each cleaning tank is equipped with an independent control system to adapt to different cleaning parameters.

[0084] The drying mechanism 300 is disposed on the support 100 and located between the cleaning mechanism 200 and the unloading part 120 along the first direction. The drying mechanism 300 is used to dry the cleaned parts after they have been cleaned by the cleaning mechanism 200.

[0085] The drying mechanism 300 refers to a treatment device for removing moisture from the surface of the cleaned parts. Specifically, it can be implemented using a hot air circulation system in conjunction with a sealed cavity. Its installation position ensures that the cleaned parts directly enter the drying process after completing the final cleaning step. The drying mechanism 300 is located adjacent to the last cleaning tank, reducing the moisture evaporation time by shortening the transfer distance of the cleaned parts.

[0086] The conveying mechanism 400 is mounted on the support 100 and is used to convey the cleaning parts on the multiple ultrasonic cleaning tanks, the drying mechanism 300 and the unloading section 120 along the direction from the loading section 110 to the unloading section 120.

[0087] Among them, the handling mechanism 400 can refer to the execution device that realizes the transfer of materials across workstations. Specifically, it can be achieved by using a track-type robotic arm in conjunction with a lifting mechanism, and its movement trajectory precisely corresponds to the spatial coordinates of each processing workstation.

[0088] In some embodiments, the conveying mechanism 400 can convey the cleaning parts from the loading section 110 to the first ultrasonic cleaning tank adjacent to the loading section 110 in the cleaning mechanism 200, and convey the cleaning parts to the next ultrasonic cleaning tank for cleaning when the previous ultrasonic cleaning process is completed. When the cleaning mechanism 200 has finished cleaning the cleaning parts, the conveying mechanism 400 will further convey the cleaning parts to the drying mechanism 300 for drying. When the cleaning parts are dried, the conveying mechanism 400 will finally convey the cleaning parts to the unloading section 120, waiting for the operator to convey the cleaning parts of the unloading section 120 to other workshops.

[0089] This application provides a cleaning device. The cleaning mechanism 200 integrates multiple ultrasonic cleaning tanks arranged along a first direction on a support 100. The cleaning device can transport the parts to be cleaned at each station according to the arrangement of the ultrasonic cleaning tanks via a transport mechanism 400, enabling multi-round cleaning of the parts. This avoids back-and-forth transport between multiple independently set cleaning tanks, eliminates waiting time between processes, increases throughput per unit time, and improves cleaning efficiency, thus helping to meet the needs of large-scale production. Using ultrasonic cleaning tanks for cleaning parts reduces surface impurities and improves cleaning quality compared to existing spray cleaning methods. The transport mechanism 400 saves manual labor and improves transport efficiency. The drying mechanism 300 is positioned adjacent to the last ultrasonic cleaning tank, reducing moisture evaporation time by shortening the transfer distance of the clean parts.

[0090] refer to Figure 1 and Figure 2In some embodiments, the cleaning equipment may also include a sealed cover 10 and an exhaust device 20 connected to each other. The sealed cover 10 covers the drying mechanism 300 and the cleaning mechanism 200. The exhaust device 20 can extract the atomized cleaning liquid during the cleaning process to a designated location for treatment, so as to avoid the evaporation of the cleaning solution and the resulting irritating gas filling the workshop.

[0091] refer to Figure 1 and Figure 2 In some embodiments, the cleaning equipment may also include a control mechanism, which can be mounted on the support 100 and electrically connected to a plurality of ultrasonic cleaning tanks, a drying mechanism 300 and a conveying mechanism 400 in the cleaning mechanism 200.

[0092] The control mechanism is used to control multiple ultrasonic cleaning tanks to clean the parts, control the conveying mechanism 400 to move along the direction from the loading section 110 to the unloading section 120, and control the drying mechanism 300 to clean the parts.

[0093] In some embodiments, the control mechanism can be used to control the cleaning time of the cleaning parts in each ultrasonic cleaning tank. For example, the control mechanism controls the dwell time and transfer rhythm of the cleaning parts between each station through a preset program. When the cleaning parts are transported from the loading section 110 to the first ultrasonic cleaning tank, the ultrasonic waves and the cleaning fluid work together to remove surface contaminants. After the current process is completed, the transport mechanism 400 transfers the cleaning parts to the next ultrasonic cleaning tank for deep treatment. Finally, the parts enter the hot air environment of the drying mechanism 300 to remove residual liquid, forming a continuous processing flow.

[0094] By setting up a control mechanism, the cleaning equipment can achieve continuous and automated processing of the parts to be cleaned, eliminating the waiting time of the parts in the process, increasing the throughput per unit time, and helping to meet the needs of large-scale production.

[0095] refer to Figure 1 and Figure 2 In some embodiments, the cleaning equipment may further include a laser sensor disposed in the loading section 110 and electrically connected to the control mechanism. The laser sensor is used to send an electrical signal to the control mechanism when it detects that there is a cleaning part in the loading section 110, so that the control mechanism controls the conveying mechanism 400 to convey the cleaning part to the cleaning mechanism 200.

[0096] By setting up laser sensors, the cleaning equipment can automatically identify the cleaning parts in the loading section 110, avoiding the need for manual monitoring of whether there are cleaning parts in the loading section 110. This reduces labor costs, improves the automation level of the cleaning equipment, and shortens the working time of the entire cleaning process, thereby improving the cleaning efficiency of the cleaning equipment.

[0097] refer to Figure 1 and Figure 3 In some embodiments, the drying mechanism 300 may include a drying tank 310 and an air supply assembly 320. The drying tank 310 is disposed on the support 100 and is used to hold the cleaned items after cleaning by the cleaning mechanism 200. The air supply assembly 320 is disposed at the opening of the drying tank 310 and is used to supply hot air to the cleaned items in the drying tank 310. The airflow direction supplied by the air supply assembly 320 to the cleaned items may be perpendicular to a first direction to achieve air supply for processing the cleaned items in the drying tank 310.

[0098] The drying tank 310 can refer to a container with a cavity, specifically a rectangular tank welded from stainless steel. Its internal space is used to hold the cleaning items, and a drain pipe 330 is installed at the bottom of the tank to drain condensate. The air supply assembly 320 can refer to a device that generates a directional hot airflow.

[0099] Specifically, after undergoing multi-stage cleaning in multiple ultrasonic cleaning tanks, the cleaning components are transferred by the conveying mechanism 400 to the drying tank 310. Upon activation of the air supply assembly 320, a hot airflow is generated along the second direction (e.g., ...). Figure 3 The airflow (in the Y direction) acts perpendicularly to the surface of the cleaned parts. The airflow penetrates the gaps in the basket 410, carrying away moisture, forming a unidirectional flow path from top to bottom within the tank, avoiding uneven drying caused by airflow turbulence. The layout, with the second direction orthogonal to the direction of the cleaned parts' transport, ensures that the drying stations are spatially perpendicular within the longitudinal arrangement of the equipment. This prevents hot air backflow from affecting upstream cleaning stations and reduces the lateral space occupied by the equipment. The air supply position above the tank opening shortens the hot air delivery distance, and the drain pipe 330 at the bottom of the tank promptly discharges condensate, preventing secondary adhesion.

[0100] This solution enhances airflow penetration through a vertical air delivery path and optimizes equipment space utilization through an orthogonal layout. Compared to single-station drying equipment, this structure can form a continuous production line with multi-stage cleaning stations, achieving automated integration of cleaning and drying processes.

[0101] Through the above technical solution, this application effectively solves the problem of residual moisture on the surface of the cleaned parts. The vertical air supply method ensures that hot air evenly covers the surface of the cleaned parts, and the orthogonal layout avoids wasting equipment space.

[0102] refer to Figure 1 and Figure 3 In some embodiments, the air supply assembly 320 may include a fan 321 and a heating element. The fan 321 is used to supply airflow to the drying chamber 310. The heating element is disposed between the fan 321 and the drying chamber 310, and is used to heat the airflow supplied to the drying chamber 310. The bottom wall of the drying chamber 310 has a drain pipe 330 communicating with the bottom wall of the drying chamber 310.

[0103] The fan 321 can refer to a device that generates directional airflow through mechanical movement, specifically an axial flow fan 321 or a centrifugal fan 321, which enhances the airflow efficiency within the drying tank 310 through forced airflow. The heating element can refer to a component that converts electrical energy into heat energy, specifically a finned heating tube 800 or a resistance wire heater, which preheats the airflow before it enters the drying tank 310 by being positioned in the airflow path. The drain pipe 330 can refer to a pipe connecting the bottom of the drying tank 310 to an external drainage system, specifically a PVC pipe with a filter screen, which continuously drains accumulated liquid from the tank to prevent residual liquid buildup.

[0104] Specifically, the airflow generated by the fan 321 is uniformly heated as it passes over the heating element, forming a stable temperature hot airflow that is then blown vertically into the drying tank 310 along the second direction. The axial arrangement of the heating element and the fan 321 shortens the heat conduction path, ensuring temperature stability of the airflow during transport. The drain pipe 330 at the bottom of the drying tank 310 forms a continuous drainage channel with the tank interior. During the hot air drying process, liquid detached from the surface of the cleaned parts flows to the bottom of the tank under gravity and is discharged in real time through the drain pipe 330. This structure simultaneously removes liquid during the hot air circulation process, preventing surface contamination caused by secondary evaporation of liquid and preventing water accumulation in the tank from corroding the heating element.

[0105] Through the above technical solution, this application effectively eliminates secondary pollution caused by cleaning fluid residue on the surface of the cleaned parts. The synergistic effect of directional hot air conveying and active drainage design ensures rapid evaporation and timely removal of moisture from the surface of the cleaned parts during the drying process. This structure improves drying efficiency while reducing equipment maintenance requirements and avoiding the risk of component damage due to liquid residue. It is particularly suitable for drying aluminum-plastic film materials with multi-layer composite structures.

[0106] refer to Figure 1 and Figure 3 In some embodiments, the drying mechanism 300 may further include a sealing cover 340 and a first lifting member 350. A heating element is disposed within the sealing cover 340, and a fan 321 is connected to the sealing cover 340. The first lifting member 350 is used to move the sealing cover 340 to open or seal the opening of the drying chamber 310.

[0107] The sealing cover 340 can refer to a closed structure covering the opening of the drying tank 310, and can be made of stainless steel and welded together. The first lifting component 350 can refer to an actuator that drives the sealing cover 340 to move vertically, and can be implemented by a cylinder or an electric push rod. The lifting trajectory is controlled by a linear guide rail to ensure that the sealing cover 340 is completely in contact with the tank opening plane.

[0108] Specifically, after the cleaned parts enter the drying tank 310, the first lifting component 350 drives the sealing cover 340 to press down to the opening of the tank, forming a sealed space. The fan 321 continuously injects heated airflow into the sealing cover 340, and the hot air circulates in the closed environment, causing the moisture on the surface of the cleaned parts to evaporate quickly. After drying is completed, the first lifting component 350 lifts the sealing cover 340 to release the seal, making it easier for the handling mechanism 400 to remove the cleaned parts.

[0109] Compared to existing technologies, traditional drying equipment often has its drying tank openings in an open state, resulting in significant heat loss and steam permeating the workshop. This solution uses a dynamic sealing structure to form a closed thermal circulation system during the drying stage, reducing heat loss; the lifting sealing cover 340 automatically releases the seal during non-working periods, preventing energy waste when the equipment is idling.

[0110] Through the above technical solution, this application effectively solves the problems of low heat energy utilization and workshop environment pollution during the drying process, and achieves energy saving while ensuring drying efficiency. The automatic lifting function of the sealing cover 340 is synchronized with the production line rhythm to meet the needs of continuous production.

[0111] refer to Figure 1 and Figure 4 In some embodiments, the transport mechanism 400 may include at least one basket 410, a moving component 420, and a detection sensor.

[0112] At least one basket 410 is used to hold the cleaning items. The basket 410 can refer to a carrier container used to fix the cleaning items, and can be implemented as a metal mesh basket structure with hooks. The hook design facilitates cooperation with the gripping mechanism of the moving component 420, thereby improving the connection stability between the basket 410 and the moving component 420.

[0113] There can be multiple baskets 410, with one basket 410 corresponding to each ultrasonic cleaning tank, and one basket 410 corresponding to each drying mechanism 300. The loading section 110 can also have baskets 410, and the parts to be cleaned can be placed directly into the baskets 410 of the loading section 110. Alternatively, baskets 410 can be used to transport the parts to be cleaned from other workshops to the loading section 110 of the cleaning equipment.

[0114] In some embodiments, both the ultrasonic cleaning tank and the drying tank 310 can be provided with positioning plates for limiting and positioning the basket 410. By providing positioning plates, the position of the basket 410 in the ultrasonic cleaning tank or the drying tank 310 can be limited, thereby improving the installation accuracy and installation stability of the basket 410 in the ultrasonic cleaning tank and the drying tank 310.

[0115] The moving component 420 is mounted on the support 100 and is used to move the basket 410 between the loading section 110, multiple ultrasonic cleaning tanks, drying mechanism 300 and unloading section 120 along the first direction.

[0116] The moving component 420 can refer to the mechanical structure that drives the spatial displacement of the suspended platform 410. Specifically, it can be implemented by a cross slide module driven by a servo motor. The suspended platform 410 is moved in three-dimensional space by the combined motion of the linear guide rail along the first direction and the lifting cylinder along the second direction.

[0117] A detection sensor is disposed on the moving component 420. The detection sensor moves with the moving component 420 along a first direction and is used to detect the position of the basket 410. A control mechanism can be electrically connected to the moving component 420 and the detection sensor so that the control mechanism can adjust the relative position of the moving component 420 and the basket 410 according to the positioning function of the detection sensor, so that the moving component 420 can grasp the basket 410 more accurately.

[0118] Among them, the detection sensor can refer to the detection device that monitors the position of the suspended platform 410 in real time. Specifically, it can be implemented by using a laser rangefinder or a photoelectric sensor, and its installation position is synchronized with the moving parts of the moving component 420.

[0119] Specifically, after the suspended basket 410 is connected to the gripping mechanism of the moving component 420 via a hook, the moving component 420 sequentially moves the suspended basket 410 to various ultrasonic cleaning tanks, the drying mechanism 300, and the unloading section 120 along a preset path. When the moving component 420 moves horizontally and needs to grip the suspended basket 410, the detection sensor, which moves synchronously with the moving component 420, continuously scans the real-time position of the suspended basket 410, and the control mechanism immediately corrects the movement trajectory of the moving component 420. During vertical lifting, the sensor synchronously monitors the distance between the suspended basket 410 and each cleaning tank, ensuring that the moving component 420 can accurately grip the suspended basket 410. This closed-loop system of position detection and motion control effectively eliminates positioning errors caused by manual operation.

[0120] This solution integrates the detection sensor onto the moving component 420, thereby synchronizing position detection and motion control and avoiding process interruptions caused by manual intervention.

[0121] Through the above technical solution, this application achieves fully automatic real-time detection of the position of the suspended platform 410, eliminating operational errors from manual calibration and improving the accuracy of the moving component 420 when gripping the suspended platform 410. The detection data is directly fed back to the control system, ensuring precise alignment between the moving component 420 and the suspended platform 410, and avoiding equipment downtime due to gripping failures. The synergistic effect of the detection sensors and the moving mechanism shortens the cleaning cycle time, increases the single-batch processing capacity, and meets the needs of continuous production.

[0122] refer to Figure 1 and Figure 4 In some embodiments, the moving component 420 may include a second lifting member 421 and a linear unit 422. The second lifting member 421 is used to drive the suspended basket 410 to move up and down along a second direction, which is perpendicular to the first direction. The linear unit 422 is connected to the second lifting member 421, and the linear unit 422 moves with the second lifting member 421 along the first direction, and the linear unit 422 is used to drive the second lifting member 421 and the suspended basket 410 to move along the second direction.

[0123] The second lifting component 421 can refer to a mechanism that vertically drives the suspended basket 410 to move along the second direction. Specifically, it can be implemented using a hydraulic cylinder, a lead screw driven by a servo motor, or a gear and rack mechanism. Its function is to adjust the contact position of the suspended basket 410 with cleaning tanks of different depths by vertically lifting and lowering it, ensuring that the suspended basket 410 remains stable when immersed in the cleaning solution or removed from the work station. The linear unit 422 can refer to a mechanism that drives the second lifting component 421 and the suspended basket 410 to move along the first direction. Specifically, it can be implemented using a linear motor, a ball screw, or a synchronous belt drive mechanism. Its function is to sequentially transport the suspended basket 410 to multiple ultrasonic cleaning tanks, the drying mechanism 300, and the unloading section 120 through horizontal linear motion, reducing positioning errors during multi-station switching.

[0124] Specifically, the second lifting component 421 and the linear unit 422 form an orthogonal motion system. When the linear unit 422 moves along the first direction, the second lifting component 421 simultaneously drives the basket 410 to complete the horizontal cross-station transport. When the basket 410 reaches the target station, the second lifting component 421 independently controls the basket 410 to rise and fall along the second direction, so that it is accurately immersed in the ultrasonic cleaning tank or lifted to the detachment position.

[0125] This solution separates and controls horizontal conveying and vertical positioning through orthogonal dual-axis coordinated motion. This eliminates mechanical interference during multi-station switching and ensures the synchronization accuracy of the two-axis motion through a rigid connection structure, thereby improving the transfer speed while avoiding positioning deviation.

[0126] Through the above technical solutions, this application achieves precise positioning and automated transfer of the suspended platform 410 between continuous workstations, solving the problem of low cleaning efficiency caused by insufficient positioning accuracy of traditional equipment. At the same time, the decoupling design of the motion axis reduces the frequency of manual intervention, ensuring continuous and stable operation of the cleaning process.

[0127] refer to Figure 1 and Figure 5 In some embodiments, the multiple ultrasonic cleaning tanks may include a first ultrasonic cleaning tank 210, a second ultrasonic cleaning tank 220, and a third ultrasonic cleaning tank 230.

[0128] The first ultrasonic cleaning tank 210, located near the loading section 110, is used for the first cleaning of the parts to be cleaned at the loading section 110. The second ultrasonic cleaning tank 220, located between the first ultrasonic cleaning tank 210 and the unloading section 120, is used for the second cleaning of the parts after the first cleaning. The third ultrasonic cleaning tank 230, located between the second ultrasonic cleaning tank 220 and the unloading section 120, is used for the third cleaning of the parts after the second cleaning. The first ultrasonic cleaning tank 210 can be used for rough cleaning of the parts, the second ultrasonic cleaning tank 220 can be used for fine cleaning of the parts, and the third ultrasonic cleaning tank 230 can be used for rinsing the parts.

[0129] The first ultrasonic cleaning tank 210 can refer to the primary treatment unit near the feeding section 110, and can be implemented using a tank structure with built-in ultrasonic transducers and cleaning fluid, used to remove large particulate contaminants from the surface of the parts being cleaned. The second ultrasonic cleaning tank 220 can refer to the intermediate treatment unit located between the primary treatment unit and the final treatment unit, used to decompose stubborn oil stains and micron-sized impurities. The third ultrasonic cleaning tank 230 can refer to the final treatment unit near the material output end, and can be implemented using a combination structure of a clean water circulation system and an ultrasonic generator, used to remove residual cleaning agent and complete surface purification.

[0130] Specifically, three cleaning tanks are arranged linearly along the material conveying direction to form a continuous processing channel. As the parts to be cleaned pass through the cleaning tanks sequentially via the conveying mechanism 400, the first ultrasonic cleaning tank 210 uses mechanical impact to remove surface contaminants, the second ultrasonic cleaning tank 220 uses chemical cleaning agents to penetrate and decompose deep-seated contaminants, and the third ultrasonic cleaning tank 230 uses clean water rinsing to remove chemical residues. Each cleaning tank is independently configured with ultrasonic frequency parameters. The parts to be cleaned undergo graded processing during continuous movement, avoiding efficiency losses caused by repeated soaking.

[0131] This solution utilizes a multi-stage cleaning tank design with spatial separation, allowing for simultaneous rough washing, fine washing, and rinsing processes. The transfer time between cleaning stations overlaps with the processing time, achieving true continuous production. Simultaneously, independently controlled cleaning parameters enable optimization of each processing stage for specific contaminants, overcoming the limitation of single cleaning conditions that cannot accommodate different types of contaminants.

[0132] Through the above technical solution, this application effectively solves the production efficiency bottleneck of single-station equipment. The staged treatment mechanism removes contaminants of different properties separately in a dedicated cleaning environment, achieving micron-level cleanliness on the surface of the cleaned parts and reducing the total amount of residue to one-tenth of that of traditional processes. The continuous assembly line operation mode eliminates waiting time between processes and improves the utilization rate of cleaning equipment.

[0133] refer to Figure 1 and Figure 5 In some embodiments, the cleaning equipment may also include a water source and a solution mixing tank.

[0134] The water source is used to inject clean water into the third ultrasonic cleaning tank 230. The water source can be a supply system that provides clean water for the rinsing stage. Specifically, it can be achieved by using a tap water pipeline in conjunction with a solenoid valve. The control mechanism is electrically connected to the solenoid valve, and the amount of clean water injected is adjusted by controlling the opening and closing of the valve to ensure that no clean water residue is used in the rinsing stage.

[0135] The mixing tank is connected to a water source and is used to prepare the cleaning solution. It also injects the cleaning solution into the first ultrasonic cleaning tank 210 and the second ultrasonic cleaning tank 220. The mixing tank can be a container for mixing the cleaning agent and water, specifically a sealed tank equipped with a stirrer and a level sensor 700. The concentration of the cleaning solution is controlled by a proportioning device to ensure that targeted cleaning agents are used in the rough and fine cleaning stages. The mixing tank is connected to the first ultrasonic cleaning tank 210 and the second ultrasonic cleaning tank 220 via pipelines, each equipped with a solenoid valve. A control mechanism is connected to these solenoid valves to control the injection volume of the cleaning solution into the first and second ultrasonic cleaning tanks 210 and 220.

[0136] Specifically, during the rinsing stage, clean water is continuously injected into the third ultrasonic cleaning tank 230 from the water source to remove the cleaning solution residue from the previous process; the prepared cleaning solution is injected into the first and second ultrasonic cleaning tanks 220 from the mixing tank to perform graded cleaning according to different levels of contamination.

[0137] In some embodiments, the first ultrasonic cleaning tank 210 is connected to the third ultrasonic cleaning tank 230, so that water from the third ultrasonic cleaning tank 230 is injected into the first ultrasonic cleaning tank 210. When the connection structure is activated, the water rinsed in the third ultrasonic cleaning tank 230 is transferred to the first ultrasonic cleaning tank 210 via a fluid exchange pump as a supplementary water source for the coarse cleaning stage. The two technical approaches can be implemented individually or in combination: when the mixing tank is used alone, the cleaning solution concentration is precisely controlled by a proportional adjustment device; when the connection structure is activated alone, the rinsing water enters the coarse cleaning tank via a circulation path for reuse; when both are combined, water resource utilization is maximized while ensuring a stable cleaning agent concentration.

[0138] This solution achieves precise concentration of cleaning solution through a mixing tank, avoiding fluctuations in cleaning quality caused by concentration deviations; it establishes a rinsing water circulation path through a connected structure of the cleaning pools, reducing the consumption of clean water; and it combines graded cleaning with recycling, improving cleaning quality while reducing water waste.

[0139] Through the above technical solutions, this application solves the problem of pollutant residue caused by cleaning fluid residue, reduces the risk of secondary pollution by rinsing with clean water and recycling; improves the decontamination efficiency by injecting cleaning fluid of different concentrations in stages, and ensures the cleanliness of the surface of the cleaned parts; and reduces the consumption of clean water by reusing the rinsing water in the third ultrasonic cleaning tank 230 to the coarse cleaning stage of the first ultrasonic cleaning tank 210, thereby achieving efficient utilization of resources.

[0140] refer to Figure 1 and Figure 5 In some embodiments, the cleaning device may also include an injection line 500 and an overflow line 600.

[0141] The injection pipeline 500 connects the liquid preparation tank and the first ultrasonic cleaning tank 210. The injection pipeline 500 is equipped with an injection pump and a solenoid valve. The injection pump delivers the cleaning solution from the liquid preparation tank to the first ultrasonic cleaning tank 210. Both the solenoid valve and the injection pump are electrically connected to a control mechanism, which controls the opening and closing of the solenoid valve and the start and stop of the injection pump, thereby controlling the injection volume in the first ultrasonic cleaning tank 210.

[0142] It is understood that there can be multiple injection lines 500, with each ultrasonic cleaning tank corresponding to one injection line 500 connected to a solution tank or a water source. Each injection line 500 can be equipped with an injection pump and a solenoid valve to control the injection volume in each ultrasonic cleaning tank via a control mechanism. For example, the second ultrasonic cleaning tank 220 can be connected to a solution tank via an injection line 500, and the third ultrasonic cleaning tank 230 can be connected to a water source via an injection line 500.

[0143] The overflow pipe 600 is connected to the first ultrasonic cleaning tank 210 and is used to discharge the cleaning fluid in the first ultrasonic cleaning tank 210 that is higher than the overflow pipe 600. The overflow pipe 600 can refer to a liquid discharge channel set on the side wall or bottom of the cleaning tank. The height of the overflow port is matched with the working depth of the ultrasonic transducer plate. Its function is to automatically start overflow discharge when the liquid level exceeds a set threshold, forming a dynamic liquid level balance mechanism.

[0144] In some embodiments, both the second ultrasonic cleaning tank 220 and the third ultrasonic cleaning tank 230 may be provided with an overflow pipe 600, and the overflow pipe 600 has the same function as the overflow pipe 600 on the first ultrasonic cleaning tank 210.

[0145] Specifically, the injection line 500 pumps the cleaning solution from the mixing tank into the first ultrasonic cleaning tank 210 via an injection pump. When the level sensor 700 detects that the liquid level has reached a preset height, the injection pump stops working. If excessive liquid is injected due to other reasons, the overflow line 600 discharges the excess liquid through an overflow port at a fixed height. This closed-loop control system ensures that the liquid level is always maintained within the optimal working depth range of the ultrasonic transducer through real-time liquid level monitoring and mechanical overflow. The liquid discharged from the overflow line 600 can be purified and then re-enter the mixing tank, forming a recycling path for the cleaning solution.

[0146] This solution, through the dual protection of a mechanical overflow structure and an electronic control system, can still maintain a safe liquid level through the overflow pipe 600 even if the liquid level sensor 700 fails.

[0147] Through the above technical solution, this application achieves precise closed-loop control of the liquid level in the first ultrasonic cleaning tank 210, effectively preventing equipment failure and waste of cleaning fluid caused by abnormal liquid level.

[0148] refer to Figure 1 and Figure 5 In some embodiments, the cleaning device may also include a liquid level sensor 700 and / or a heating element 800.

[0149] A liquid level sensor 700 is installed inside the first ultrasonic cleaning tank 210 to detect the liquid level inside the first ultrasonic cleaning tank 210. A heating tube 800 is installed inside the first ultrasonic cleaning tank 210 to heat the cleaning solution inside the first ultrasonic cleaning tank 210.

[0150] The liquid level sensor 700 can be a detection device used to monitor the liquid level in the cleaning tank in real time. Specifically, it can be a float-type liquid level sensor 700 or a capacitive liquid level sensor 700. The liquid level sensor 700 can be electrically connected to a control mechanism, which can acquire the liquid level data in the first ultrasonic cleaning tank 210 transmitted by the liquid level sensor 700 in real time and control the injection volume of the cleaning fluid in the first ultrasonic cleaning tank 210 based on the liquid level data. Furthermore, the liquid level sensor 700 triggers liquid level control logic by detecting changes in liquid level, preventing the heating element 800 from being exposed due to excessively low liquid levels. The heating element 800 can be a heating element that is directly immersed in the cleaning fluid for heat conduction, specifically a stainless steel electric heating element or a quartz heating element 800. The heating element 800 raises the temperature of the cleaning fluid through contact heating, ensuring the synergistic effect of the cleaning agent activity and the ultrasonic cavitation effect. The heating element 800 can also be connected to the control mechanism, which can adjust the temperature of the cleaning fluid in the first ultrasonic cleaning tank 210 according to the actual needs of the cleaning parts, so as to achieve the best cleaning effect on the cleaning parts.

[0151] In some embodiments, the second ultrasonic cleaning tank 220 and the third ultrasonic cleaning tank 230 are also respectively equipped with a liquid level sensor 700 and a heating tube 800, so as to ensure the amount and temperature of the cleaning fluid added to the second ultrasonic cleaning tank 220 and the third ultrasonic cleaning tank 230, and ensure the cleaning effect on the cleaning parts.

[0152] This solution achieves dual closed-loop control of liquid level and temperature by combining a built-in liquid level sensor 700 with an immersion heating tube 800, thus solving the problems of high heat loss and slow response to abnormal liquid level caused by external heating.

[0153] Through the above technical solution, this application effectively avoids the heating element 800 dry-burning accident caused by liquid level drop, extending the service life of the equipment. Simultaneously, by precisely controlling the cleaning fluid temperature, the ultrasonic cavitation effect and the chemical reaction efficiency of the cleaning agent are optimized, significantly improving the removal effect of grease contaminants on the surface of the cleaned parts. Automated control of liquid level and temperature reduces the need for manual intervention, ensuring the consistency and safety of the cleaning process.

[0154] In some embodiments, each ultrasonic cleaning tank may also be equipped with a drain pipe to drain the cleaning fluid from each ultrasonic cleaning tank, facilitating timed cleaning or replacement of the cleaning fluid. The drain pipe may also be equipped with a solenoid valve and a drain pump, which are electrically connected to a control mechanism. The control mechanism controls the draining process of each ultrasonic cleaning tank by controlling the opening and closing of the solenoid valve and the start and stop of the drain pump.

[0155] The cleaning equipment can also be equipped with a collection tank, which is connected to the drain pipe of each ultrasonic cleaning tank. The collection tank is used to collect the waste liquid discharged from each ultrasonic cleaning tank by the drain pipe, avoiding the random discharge of waste liquid and helping to protect the working environment.
