Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a cavitation effect enhancing device of an ultrasonic cleaning machine and a precise descaling method for multi-material workpieces. BACKGROUND

[0002] The ultrasonic cleaning machine realizes efficient non-contact cleaning by using cavitation effect and is widely used in the fields of mechanical manufacturing, electronic components, medical devices, optical lenses, etc. This equipment converts high-frequency electrical signals into high-frequency mechanical vibrations, and then makes the cleaning liquid produce a large number of micro cavitation bubbles. These bubbles continuously grow, shrink and eventually collapse under the action of the sound field, forming local micro-jets and shock waves, thereby effectively removing oil stains, impurities, oxide layers and fine particles on the surface of the workpiece.

[0003] The ultrasonic cleaning machine in the prior art generally adopts a single ultrasonic output structure with fixed frequency and fixed power, which may result in insufficient cavitation effect. Specifically, the dissolved gas in the cleaning liquid is difficult to be effectively removed, the sound field distribution is uneven, and the power density is low, thereby reducing the number of cavitation bubbles and weakening the collapse energy. In this case, the cleaning machine is prone to form cleaning blind areas in deep holes, blind holes and complex cavities, making it difficult to completely remove stubborn dirt.

[0004] In addition, the conventional ultrasonic cleaning machine also has consistency problems in cleaning effect: due to the obvious standing wave effect in the sound field and poor liquid flow circulation, the force received by the workpiece at different positions is uneven, resulting in inconsistent cleaning effect. In this case, the workpiece may have problems of local incomplete cleaning or local over-cleaning, especially when processing multi-material and multi-specification workpieces, batch stable cleaning is difficult to achieve.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: like Figures 1 to 5 As shown in one embodiment of the present invention, a cavitation effect enhancement device for an ultrasonic cleaner is installed on the ultrasonic cleaner and works in conjunction with the ultrasonic transducer and the cleaning tank. Specifically, it includes an intelligent control mechanism 1, a water jet mechanism 2, a monitoring mechanism 8, a swing component, a circulation component, and a sealing and protection component, which can realize dynamic enhancement of the cavitation effect and precise control of the cleaning effect.

[0023] Specifically, the intelligent control mechanism 1 is installed on the ultrasonic cleaner and can receive and analyze various monitoring signals from the monitoring mechanism 8 in real time. It then outputs control commands according to a preset algorithm to adjust the operating parameters of the water jet mechanism 2, the ultrasonic transducer, and the circulation components, achieving continuous stepless adjustment of the power of the ultrasonic transducer and each component. Furthermore, the intelligent control mechanism 1 integrates a storage module and a communication module. The storage module uses an SD card and can store at least 100 sets of cleaning parameter schemes for easy retrieval during batch cleaning. The communication module supports both RS485 and Bluetooth communication. RS485 communication enables centralized control of multiple cleaners, while Bluetooth communication allows for remote monitoring and parameter adjustment via a mobile app, improving operational convenience.

[0024] like Figures 1 to 7 As shown, the water jet mechanism 2 is located inside the cleaning tank. It is used to impact the workpiece within the tank by spraying water, suspending the workpiece in the cleaning solution and preventing it from contacting the tank walls to avoid creating cleaning blind spots. Simultaneously, it agitates the cleaning solution, promoting the generation and collapse of cavitation bubbles and enhancing the cavitation effect. The water jet mechanism 2 includes multiple jetting components, the number of which is determined by the volume and size of the cleaning tank. These components are evenly distributed within the tank to ensure that the water flow comprehensively covers the workpiece.

[0025] Specifically, the spraying assembly consists of multiple first water pipes 21. The first water pipes 21 are made of stainless steel with an outer diameter of 20-30mm and a wall thickness of 2-3mm. They are corrosion-resistant, high-temperature resistant, and pressure-resistant. Each first water pipe 21 is welded with multiple electrically controlled nozzles 22 to increase the contact area between the cleaning fluid and the workpiece, while also enhancing the impact of the water flow on the surface of the workpiece and promoting the removal of dirt.

[0026] The number of electrically controlled nozzles 22 is set according to the length of the first water pipe 21, and the distance between two adjacent electrically controlled nozzles 22 is 50-80mm to ensure the uniformity of water flow.

[0027] The machine body is equipped with a first water pump 5 and a water tank 7 in the mounting cavity. The first water pump 5 is a stainless steel centrifugal pump, which has the characteristics of stable flow, low noise and long service life. The inlet and outlet of the first water pump 5 are equipped with filter screens with a pore size of 50-100 mesh, which are used to filter large particles of dirt in the cleaning solution and prevent clogging of the nozzle and water pipe.

[0028] The water tank 7 is equipped with a liquid level sensor and a temperature sensor. The liquid level sensor is a float-type liquid level sensor, which can monitor the liquid level in the water tank 7 in real time. When the liquid level is lower than the preset value, it sends a signal to the intelligent control mechanism 1, which then issues an alarm to remind the operator to add cleaning fluid. The temperature sensor can monitor the temperature of the cleaning fluid in real time. The intelligent control mechanism 1 adjusts the heating device of the water tank 7 according to the temperature data to control the temperature of the cleaning fluid at 40-60℃. This temperature range can effectively improve the cavitation effect intensity while avoiding damage to the workpiece caused by high temperature.

[0029] A third water pipe 4 is welded onto the first water pump 5. The end of the third water pipe 4 away from the water tank 7 is connected to the swing assembly of the water jet mechanism 2 to realize the delivery of cleaning fluid.

[0030] In use, the intelligent control mechanism 1 controls the power of the first water pump 5 through the water pump drive circuit, thereby controlling the water flow rate and spray pressure of the electronically controlled nozzle 22. The water flow rate is adjusted between 0.5-2.0 m³ / h based on the material, size, and type of dirt on the workpiece. 3 The spray pressure is adjusted to 0.2-0.5 MPa per hour to ensure that the workpiece is stably suspended in the cleaning solution. The suspension height is controlled at 5-15 cm below the surface of the cleaning tank. This prevents the workpiece from floating too high and exposing part of its surface to the air, and also prevents the workpiece from sinking and contacting the bottom of the tank to form a blind zone. At the same time, the impact of the water flow can disturb the cleaning solution, promote the removal of dissolved gases in the cleaning solution, increase the number of cavitation bubbles, enhance the cavitation effect, and improve the cleaning ability.

[0031] Example 2: like Figures 1 to 8 As shown, in order to further enhance the water flow disturbance effect, break the standing wave effect in the sound field, enable the workpiece to move in all directions in the cleaning liquid, and eliminate cleaning blind spots, a swing component is set between the spray component and the third water pipe 4. During the cleaning process, the swing component controls the spray component to swing back and forth, disturbing the water flow in the cleaning tank, so that the workpiece moves up and down and left and right, achieving 360° cleaning without dead angles.

[0032] Specifically, the swing assembly includes a second water pipe 3, a motor 33, a first pulley 31, a second pulley 331, a belt 34, and a rotary joint 32. The motor 33 is welded to the outer wall of the intelligent control mechanism 1, and its rotating shaft is welded to the second pulley 331. The first pulley 31 is fixedly connected to the second water pipe 3 by welding. The diameter ratio of the first pulley 31 to the second pulley 331 is 1:1, ensuring that the motor 33's rotational speed can be converted into a suitable swing speed. A belt 34 is fitted between the first pulley 31 and the second pulley 331. The belt 34 is a synchronous belt with a toothed surface, achieving a transmission efficiency of ≥95% to prevent slippage during transmission and ensure precise control of the swing angle.

[0033] One end of the second water pipe 3 passes through the housing of the intelligent control mechanism 1 and the wall of the cleaning tank, extending into the interior of the cleaning tank. The second water pipe 3 is connected to the wall of the cleaning tank by a rotary seal. The sealing structure adopts a mechanical seal. The moving ring and stationary ring of the mechanical seal are made of silicon carbide. The surface roughness of the sealing surface is ≤Ra0.2μm, and the sealing pressure is ≥2.0MPa. This ensures the free rotation of the second water pipe 3 and effectively prevents the cleaning fluid from leaking.

[0034] A connecting pipe 214 is welded to the first water pipe 21 of the spray assembly. A flange 215 is provided at the end of the connecting pipe 214. The flange 215 is made of stainless steel and is integrally welded to the connecting pipe 214. A corresponding flange 215 is also provided at the end of the second water pipe 3. The two flanges 215 are connected by bolts. A fluororubber gasket is provided between the flanges 215. The gasket is 2-3mm thick and has good high temperature resistance, corrosion resistance and sealing performance to ensure that there is no leakage of cleaning fluid during transportation.

[0035] A rotary joint 32 is installed at the end of the second water pipe 3 away from the connecting pipe 214. One end of the rotary joint 32 is welded to the second water pipe 3, and the other end is welded to the third water pipe 4. The rotary joint 32 can achieve stable connection between the second water pipe 3 and the third water pipe 4 during rotation, avoid water pipe twisting and damage, and ensure continuous delivery of cleaning fluid.

[0036] During the cleaning process, the intelligent control mechanism 1 drives the motor 33 to rotate back and forth within the range of 0-15°. The motor 33 drives the second pulley 331 to rotate, which in turn drives the first pulley 31 to rotate via the synchronous belt. This, in turn, drives the second water pipe 3 and the spray assembly to swing back and forth at a frequency of 1-2 times / second. This causes the direction of the water flow sprayed from the electronically controlled nozzle 22 to change continuously, disturbing the cleaning liquid in the cleaning tank and forming irregular water vortices. This propels the workpiece to move up and down, left and right, and back and forth in the cleaning liquid, with a movement amplitude of 5-10cm. This avoids cleaning blind spots caused by the workpiece being in the same position for a long time. At the same time, it breaks the standing wave effect in the sound field, making the sound field distribution more uniform and improving the consistency of the cleaning effect.

[0037] Example 3: To further promote the flow of the cleaning fluid, remove cavitation bubbles and detached dirt from the cleaning tank, maintain the stability of the cavitation effect, and prevent dirt from accumulating in the cleaning fluid and affecting the cleaning effect, a second water pump 6 is fixedly installed in the mounting cavity inside the machine body. The second water pump 6 is the same model and has the same parameters as the first water pump 5 to ensure the balance of the circulating flow of the cleaning fluid.

[0038] The second water pump 6 is fixedly connected to the fourth water pipe 61, which is made of the same stainless steel as the other water pipes. One end of the fourth water pipe 61 is connected to the bottom drain of the cleaning tank, and the other end of the fourth water pipe 61 is connected to the return water port of the water tank 7 to realize the recycling of the cleaning liquid.

[0039] The intelligent control mechanism 1 controls the power of the second water pump 6 through the water pump drive circuit, so that the power of the second water pump 6 is always consistent with the power of the first water pump 5. This ensures that the flow rate of the cleaning fluid delivered by the first water pump 5 into the cleaning tank is equal to the flow rate of the cleaning fluid drawn from the cleaning tank by the second water pump 6, thus maintaining a stable liquid level in the cleaning tank and preventing overflow due to excessively high liquid level or excessively low liquid level from affecting the cleaning effect.

[0040] During the cleaning fluid circulation process, the second water pump 6 draws the cleaning fluid, containing detached dirt and cavitation bubbles, from the bottom of the cleaning tank to the water tank 7. The water tank 7 is equipped with a filtration device, which adopts a multi-layer filtration structure, including a coarse filter layer, a fine filter layer, and an activated carbon filter layer, to adsorb oil and odors in the cleaning fluid. After filtration, the cleaning fluid is transported back to the water jet mechanism 2 through the first water pump 5, realizing the recycling of the cleaning fluid. This not only saves water resources but also maintains the cleanliness of the cleaning fluid and ensures the stability of the cavitation effect.

[0041] In addition, a drain outlet is provided on the water tank 7. The drain outlet is located at the bottom of the water tank 7 and is equipped with a drain valve. After the cleaning fluid has been used for a period of time, the operator can open the drain valve to drain the dirt and waste cleaning fluid that has settled in the water tank 7, so as to facilitate the replacement of new cleaning fluid and ensure the cleaning effect.

[0042] Example 4: A sealing and protective assembly is provided on the water jet mechanism 2. The sealing and protective assembly includes a first sealing bladder 212 and a second sealing bladder 221, both of which are made of fluororubber. Fluororubber has good high temperature resistance, oil resistance, corrosion resistance and sealing performance. The applicable temperature range is -20℃ to 150℃, which can adapt to the working environment of the cleaning machine.

[0043] A baffle 211 is welded inside the first water pipe 21. The baffle 211 is made of stainless steel and is 2-3mm thick. It is tightly welded to the inner wall of the first water pipe 21. The welding is done using argon arc welding to ensure sealing performance. The baffle 211 divides the first water pipe 21 into a water flow section and an equipment section. The water flow section is located on one side of the baffle 211 and is used to transport cleaning fluid. It is connected to the spray end of the electrically controlled nozzle 22. The equipment section is located on the other side of the baffle 211 and is used to install electrical control components, avoiding contact with the cleaning fluid.

[0044] One end of the electrically controlled nozzle 22 penetrates the pipe wall of the equipment section and is inserted into the water flow section. A second sealing bladder 221 is sealed at the connection between the electrically controlled nozzle 22 and the pipe wall of the equipment section. The second sealing bladder 221 is fitted onto the outer wall of the electrically controlled nozzle 22 with an interference fit. Both ends are tightly fitted to the pipe wall of the equipment section and the electrically controlled nozzle 22, respectively, to ensure that the cleaning fluid in the water flow section does not leak into the equipment section. A first sealing bladder 212 is sealed at the connection between the partition 211 and the electrically controlled nozzle 22. The first sealing bladder 212 is also fitted onto the outer wall of the electrically controlled nozzle 22 with an interference fit. Both ends are tightly fitted to the partition 211 and the electrically controlled nozzle 22, respectively, to further enhance the sealing effect. The double sealing structure can effectively prevent the cleaning fluid from leaking and protect the electrical components inside the equipment section.

[0045] Multiple electric push rods 213 are fixedly installed inside the equipment section. The electric push rods 213 are characterized by small size, high precision and low noise, making them easy to install inside the equipment section of the first water pipe 21.

[0046] Specifically, each electrically controlled nozzle 22 is symmetrically equipped with a pair of electric push rods 213. One end of the electric push rod 213 is welded to the inner wall of the equipment, and the other end is connected to the outer wall of the electrically controlled nozzle 22 through a ball joint connection. The ball joint connection can realize multi-angle rotation between the electric push rod 213 and the electrically controlled nozzle 22, ensuring that the electric push rod 213 can drive the electrically controlled nozzle 22 to swing flexibly.

[0047] A pair of electric push rods 213 work in tandem, their extension and retraction speed controlled by the drive module of the intelligent control mechanism 1. This allows the electrically controlled nozzle 22 to oscillate flexibly within a 0-30° range, further agitating the cleaning fluid and ensuring the water flow precisely impacts all parts of the workpiece, especially areas prone to cleaning blind spots such as deep holes, blind holes, and complex cavities. Simultaneously, combined with the monitoring screen of the monitoring mechanism 8, the intelligent control mechanism 1 can adjust the movement of the electric push rods 213 in real time, controlling the direction and angle of the water flow from the electrically controlled nozzle 22, ensuring that every surface of the workpiece is thoroughly cleaned and improving the cleaning effect.

[0048] A method for precise descaling of multi-material workpieces includes the following steps: S1: Inject cleaning fluid to ensure the fluid level meets the standard; adjust the cleaning fluid temperature to 40-60℃ by calling the appropriate cleaning parameter scheme through the intelligent control mechanism; S2: Place the workpiece to be cleaned into the cleaning tank and start the water jet mechanism to spray water so that the workpiece is suspended 5-15cm below the surface of the cleaning solution, avoiding contact with the tank wall and bottom. S3: Turn on the ultrasonic transducer and oscillating assembly to make the spray assembly oscillate back and forth, and the electronically controlled nozzle can flexibly adjust the angle to disturb the cleaning fluid, enhance the cavitation effect, and clean the workpiece in all directions. S4: Circulates the cleaning solution, removes dirt and impurities through the water tank filter, maintains the cleanliness of the cleaning solution, and ensures the cleaning effect. S5: After cleaning, remove the workpiece, periodically open the drain valve of the water tank to drain the dirt and waste cleaning solution, and replace with new solution for later use.
