Description

Technical Field

[0001] This invention relates to the field of ultrasonic cleaning technology, specifically to an ultrasonic processing device. Background Technology

[0002] Ultrasonic cleaning technology is a highly efficient, environmentally friendly, and non-contact cleaning method. It utilizes an ultrasonic generator to convert electrical energy into ultrasonic frequency mechanical vibrations, which are then converted into ultrasonic vibrations within the cleaning tank by a transducer. These ultrasonic waves generate tiny bubbles in the cleaning solution. Under the influence of the ultrasonic waves, these bubbles vibrate and expand rapidly, then suddenly burst, generating shock waves. These shock waves dislodge dirt and impurities from the surface of the object, while the flow and agitation of the cleaning solution further enhance the cleaning effect.

[0003] For example, the Chinese authorized patent CN217289575U, entitled "An Ultrasonic Cleaning Device," describes a cleaning box and a control box fixed to a trolley by iron feet. An ultrasonic generator is movably placed at the bottom of the cleaning box, and a cleaning frame is movably placed at the top. An ultrasonic transducer is placed inside the control box, and the ultrasonic transducer and ultrasonic generator are connected by pipes. This ultrasonic cleaning device, through the ultrasonic generator located inside the cleaning box, utilizes the cavitation, acceleration, and direct flow effects of ultrasound in liquids to directly and indirectly act on the liquid and contaminants, dispersing, emulsifying, and peeling off the contaminant layer to achieve the cleaning purpose.

[0004] While the aforementioned existing technologies utilize ultrasonic cleaning equipment to achieve cleaning functions, their workpiece feeding and discharging structures are relatively simple and cannot meet diverse cleaning needs. Existing feeding and discharging structures typically employ simple conveyor belts or robotic arms, which not only limits the adaptability and flexibility of the cleaning equipment but also affects cleaning efficiency and production benefits. Therefore, to address the current demands for high efficiency, automation, and low cost, we propose an ultrasonic processing device. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention features a feeding transmission structure consisting of a lifting reciprocating mechanism and a pushing reciprocating mechanism. The lifting reciprocating mechanism drives the connecting frame to move the lifting platform vertically back and forth. The lifting platform immerses the mesh cage containing the workpiece into the cleaning tank, where it undergoes ultrasonic treatment in conjunction with the ultrasonic mechanism. During this process, a linkage mechanism causes the push plate to move back and forth. When the lifting platform is at the bottom, the feeding mechanism feeds the mesh cage above to the temporary platform. As the lifting platform rises, the push plate gradually pushes the mesh cage above the temporary platform towards the cleaning tank. When the mesh cage on the lifting platform is aligned with the discharge mechanism, the bottom of one side of the mesh cage on the temporary platform contacts the top of the other side of the mesh cage on the lifting platform. Under the pushing force, the mesh cage on the lifting platform moves to the discharge mechanism, while the mesh cage on the temporary platform gradually enters the lifting platform. This process repeats continuously, forming automated feeding and discharging. This structure, employing the linkage of the lifting reciprocating mechanism and the pushing reciprocating mechanism, achieves high-efficiency ultrasonic treatment of the workpiece. Furthermore, the transmission structure is stable, resulting in low subsequent maintenance costs.

[0021] 2. This invention utilizes a mesh cage with adjustable space. The mesh plate is placed inside the cage, and due to the limited space, alignment is unnecessary. Releasing the lever allows the spring to reposition the insert into the slot of the limiting block, fixing the mesh plate at that position. The remaining mesh plates and floating plates are then installed sequentially. During ultrasonic treatment, the lifting platform gradually immerses in the cleaning fluid. Because the floating plate has a vacuum chamber, it floats on the cleaning fluid due to buoyancy. As the lifting platform descends, the floating plate gradually pulls up the fork-shaped lifting bracket, causing the space between adjacent mesh plates and between the mesh plate and the floating plate to gradually expand equidistantly. This increased spacing allows the workpiece to contact the cleaning fluid more fully, and combined with the tiny water bubbles generated by the ultrasound, achieves efficient cleaning. This not only reduces waste of cleaning fluid but also facilitates subsequent drying, further improving drying efficiency.

[0022] 3. This invention features a cleaning fluid circulation and filtration mechanism. During the circulation process, impurities within the cleaning fluid are blocked by the filter screen, ensuring the purity of the cleaning fluid and preventing any impact on workpiece processing. Simultaneously, as the water flows through the circulation pipe, it comes into contact with the impeller. The force conversion between the two causes the impeller to rotate, which in turn drives the rotating shaft to rotate the wheel, causing the brush to rotate at high speed. The rotating brush generates intense friction with the filter screen, thus cleaning away residual dirt and preventing clogging and ensuring effective filtration. When the circulation pump stops, the first valve is closed, and the dirt inside the circulation pipe gradually settles under gravity, flowing into the drain pipe. Finally, the operator simply needs to open the second valve to discharge the dirt. This cleaning structure requires no power intervention, effectively reducing energy consumption, and its simple structure makes maintenance and operation convenient. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Please see Figure 1-9 An embodiment of the present invention provides an ultrasonic processing device, comprising a base 1, a first fixing platform 2 disposed on one side of the front end face of the base 1 and tightly fitted to the base 1, a feeding mechanism 3 mounted above the first fixing platform 2, a temporary platform 4 disposed on one side of the upper end face of the base 1, and a second fixing platform 14 disposed on the other side of the base 1 and tightly fitted to the base 1, and a discharging mechanism 15 mounted on the upper end face of the second fixing platform 14; further comprising:

[0035] The cleaning tank 13 is located in the middle of the base 1. The height of the temporary platform 4 is higher than the upper surface of the cleaning tank 13. The height of the discharge mechanism 15 is lower than the upper surface of the cleaning tank 13. An ultrasonic mechanism is provided at the bottom of the cleaning tank 13.

[0036] The transmission box 5 is located at the rear end of the base 1 and is welded and fixed to the base 1. The transmission box 5 is equipped with a feeding transmission structure, which includes a lifting reciprocating mechanism and a pushing reciprocating mechanism. A first guide groove 6 is provided on the upper side of one side of the front end face of the transmission box 5, and a second guide groove 11 is provided on the lower side of the other side of the front end face of the transmission box 5.

[0037] The net cage 40 is installed inside the cleaning pool 13. Fork-shaped lifting brackets 30 are installed on the inner walls on both sides of the net cage 40. The net cage 40 has net plates 32 and float plates 33 arranged from bottom to top inside. There are three net plates 32. The float plates 33 have vacuum chambers 34 inside. The net plates 32 and float plates 33 have plug-in adjustment mechanisms on both sides inside.

[0038] In use, during ultrasonic cleaning, the mesh cage 40 containing the workpiece is positioned above the lifting platform 9. By turning on the drive motor, the lifting reciprocating mechanism causes the connecting frame 8 to drive the lifting platform 9 to move vertically back and forth. When the lifting platform 9 immerses the mesh cage 40 containing the workpiece into the cleaning tank 13, ultrasonic treatment is performed in conjunction with the ultrasonic mechanism. During this process, the push plate 12 moves back and forth back and forth through the linkage mechanism. When the lifting platform 9 is at the bottom, the feeding mechanism 3 sends the mesh cage 40 above to the temporary platform 4. As the lifting platform 9 rises, the push plate 12 gradually pushes the mesh cage 40 above the temporary platform 4 toward the cleaning tank. When the mesh cage 40 on the lifting platform 9 is aligned with the discharge mechanism 15, the bottom of one side of the mesh cage 40 on the temporary platform 4 contacts the top of one side of the mesh cage 40 on the lifting platform 9. Under the pushing force, the mesh cage 40 on the lifting platform 9 moves to the discharge mechanism 15. At the same time, the mesh cage 40 on the temporary platform 4 gradually enters the lifting platform 9, repeating this process to form automated feeding and discharging.

[0039] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The lifting and reciprocating mechanism includes a vertical guide rod 22, which is fixed to the transmission box 5 by bolts. A first slider 7 is installed on the outside of the vertical guide rod 22. The inner hole of the first slider 7 is slidably connected to the vertical guide rod 22, and the two sides of the outer wall of the first slider 7 are slidably limited by the first guide groove 6. A connecting frame 8 is installed at the front end of the first slider 7, and the cross frame above the connecting frame 8 is fixed to the first slider 7 by screws. A lifting platform 9 is fixedly installed at the bottom of the connecting frame 8. A drive arm 23 is installed above the rear end of the vertical guide rod 22, and one end of the drive arm 23 is connected to the vertical guide rod 22 by a connecting shaft. A first swing arm 24 is installed at the other end of the drive arm 23, and the two ends of the first swing arm 24 are respectively connected to the other end of the drive arm 23 and the rear end of the first slider 7 by rotating shafts. A drive motor is fixedly installed on the rear end face of the transmission box 5, and the output shaft of the drive motor is fixed to the connecting shaft of the drive arm 23 and the vertical guide rod 22 by a coupling.

[0040] By turning on the drive motor, the drive arm 23 is rotated through its output shaft. It works in conjunction with the first swing arm 24 and the vertical guide rod 22 to form a linkage structure. When the drive arm 23 rotates clockwise downwards, the first slider 7 moves downwards on the vertical guide rod 22 through the first swing arm 24. This causes the lifting platform 9 to immerse the mesh cage 40 containing the workpiece into the interior of the cleaning pool 13 through the connecting frame 8.

[0041] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The reciprocating feeding mechanism includes a transverse guide rod 25, a second slider 18 is mounted on the outside of the transverse guide rod 25, the inner hole of the second slider 18 is slidably connected to the transverse guide rod 25, and the upper and lower parts of the outer wall of the second slider 18 are slidably limited by the second guide groove 11. A push plate 12 is mounted on the front end of the second slider 18, and the push plate 12 is fixed to the second slider 18 by screws. A driven arm 26 is mounted on one side of the rear end of the transverse guide rod 25. A connecting shaft is fixedly mounted on one end of the driven arm 26, and the connecting shaft is rotatably engaged with the transverse guide rod 25. A second swing arm 27 is mounted on the other end of the driven arm 26, and the two ends of the second swing arm 27 are rotatably engaged with the driven arm 26 and the second slider 18, respectively. A transmission wheel 28 is fixedly mounted at the middle position of the connecting shaft on the drive arm 23 and the driven arm 26, and the two transmission wheels 28 are driven by a belt 29.

[0042] The connecting shaft of the drive arm 23 drives the transmission wheel 28 to rotate, which in turn drives the shaft at one end of the driven arm 26 to rotate under the transmission of the belt 29, so that the driven arm 26 rotates on the horizontal guide rod 25. Together with the second swing arm 27 and the vertical guide rod 22, a linkage structure is formed. When the lifting platform 9 is at the bottom, the driven arm 26 moves clockwise to a position that is close to the horizontal guide rod 25, so that the push plate 12 moves away from the washing pool 13. At this time, the upper mesh cage 40 is sent to the temporary platform 4 through the feeding mechanism 3.

[0043] Please see Figure 5 , Figure 6 , Figure 7 and Figure 8 The insertion adjustment mechanism includes a telescopic cavity, which is located at the middle of the inner walls on both sides of the mesh plate 32 and the float plate 33. An insert block 36 is installed inside the telescopic cavity, and the insert block 36 slides and limits the telescopic cavity. A movable groove 39 is provided above the telescopic cavity, and a lever block 35 is installed inside the movable groove 39. The lever block 35 is slidably connected to the movable groove 39, and its lower end extends into the telescopic cavity and is fixed to the upper end of the insert block 36. A spring 37 is fixedly installed between the inner side of the insert block 36 and the telescopic cavity. Limiting blocks 31 are installed on the rotating shafts at the intersection of the fork-shaped lifting bracket 30's arms. The side of the limiting block 31 closest to the fork-shaped lifting bracket 30 at the intersection of the arms... The rotating shaft is connected by bearings, and the front and rear ends of the limiting block 31 are slidably limited by the sliding grooves on the inner wall of the side plate of the mesh cage 40. The limiting block 31 is provided with a slot 38 on the side away from the fork-shaped lifting bracket 30, and the slot 38 is inserted into the plug block 36. When the fork-shaped lifting bracket 30 is retracted, the distance between the mesh plates 32 and the distance between the mesh plates 32 and the floating plate 33 are both between 2-4cm. When the fork-shaped lifting bracket 30 is unfolded, the distance between the mesh plates 32 and the distance between the mesh plates 32 and the floating plate 33 are both between 8-10cm. As the distance increases, the workpiece can be more fully contacted with the cleaning fluid, and with the tiny water bubbles generated by the ultrasonic waves, efficient cleaning treatment can be achieved.

[0044] When placing the workpiece, prioritize placing it at the bottom of the mesh cage 40. Then, take a mesh plate 32 and pull the lever 35 inwards so that the insert block 36 is located inside the mesh plate 32. Place the mesh plate 32 inside the mesh cage 40. Due to the spatial limitation of the mesh cage 40, no alignment work is required. After reaching the set height, release the lever 35. Under the elastic reset of the spring 37, the insert block 36 is pushed into the slot 38 of the limiting block 31, thus fixing the mesh plate 32 at that position. Then, sequentially place the remaining mesh plates 32 and floats... During the ultrasonic treatment process, the lifting platform 9 is gradually immersed in the cleaning fluid. As the floating plate 33 has a vacuum chamber 34 inside, it can float on the cleaning fluid under the action of buoyancy. As the lifting platform 9 descends, it gradually pulls up the fork-shaped lifting bracket 30 in conjunction with the floating plate 33, thereby making the space between the adjacent mesh plates 32 and between the mesh plates 32 and the floating plate 33 gradually expand to an equal distance. As the distance increases, the workpiece can be more fully contacted with the cleaning fluid, and with the tiny water bubbles generated by the ultrasonic waves, efficient cleaning treatment can be achieved.

[0045] After cleaning, the lifting platform 9 lifts the net cage 40 until the cleaning fluid is removed. Under the action of gravity, the float and the net plate drive the fork-shaped lifting bracket to retract and reset. If the cleaned object is a flexible material, the residual cleaning fluid can be squeezed out under pressure, which not only reduces the waste of cleaning fluid, but also facilitates the subsequent drying process and further improves the drying efficiency.

[0046] Please see Figure 1 and Figure 2 The bottom of the cage 40 is made of iron. A magnet 10 is installed in the middle of the inside of the lifting platform 9, and the bottom of the magnet 10 is fixed to the lifting platform 9. The bottom of the cage 40 is magnetically attracted to the upper surface of the magnet 10.

[0047] Since the bottom of the mesh cage 40 is made of iron, when it comes into contact with the magnet block above the lifting platform 9, the magnetic force causes the two to become fixed. When the mesh cage 40 descends, it provides forces in two directions to the fork-shaped lifting bracket 30, which facilitates its stretching and avoids instability of the mesh cage 40 during ultrasonic treatment.

[0048] Please see Figure 2 The ultrasonic mechanism includes a stainless steel base plate 19, which is sealed and fixed to the bottom of the cleaning tank 13. Several transducers 20 are arranged in a rectangular array at the lower end of the stainless steel base plate 19, and the upper end face of the transducers 20 is in contact with the bottom of the stainless steel base plate 19. An ultrasonic generator 21 is provided on one side inside the base 1, and the output end of the ultrasonic generator 21 is electrically connected to the input end of the transducers 20 through wires.

[0049] The ultrasonic generator 21 converts electrical energy into ultrasonic mechanical vibration, and the transducer 20 converts the ultrasonic mechanical vibration into ultrasonic vibration in the cleaning tank 13, thereby generating tiny bubbles in the cleaning fluid. These bubbles vibrate and expand rapidly under the action of ultrasonic waves, and then suddenly burst, generating shock waves. The shock waves shake off dirt and impurities from the surface of the workpiece.

[0050] Please see Figure 1 An observation window 16 is provided at the middle position of the front end face of the base 1, and the observation window 16 is sealed to the base 1. A maintenance cabinet door 17 is provided on one side of the front end face of the base 1, and one side of the maintenance cabinet door 17 is connected to the base 1 by a hinge. A handle is installed at the front end of the maintenance cabinet door 17. The staff can observe the ultrasonic treatment of the workpiece through the observation window 16, and can also open the maintenance cabinet door 17 periodically to maintain the ultrasonic generator 21 inside.

[0051] Furthermore, the feeding mechanism 3 and the discharging mechanism 15 are composed of a frame, a transmission roller, a conveyor belt, and a servo motor. The two sets of frames are respectively fixed on the upper end face of the first fixed platform 2 and the second fixed platform 14. The transmission roller is rotatably installed on both sides of the frame, and the transmission roller forms a transmission cooperation through the conveyor belt. The output shaft of the servo motor drives one of the transmission rollers to rotate. Under the tension cooperation with the conveyor belt, it forms a movement of the upper mesh cage 40, thereby cooperating with the feeding transmission structure to achieve high-efficiency processing.

[0052] Please see Figure 1 and Figure 2 When the lifting platform 9 is in a low position, the push plate 12 maintains the maximum distance from the cleaning tank 13. Conversely, when the lifting platform 9 is in a high position, the push plate 12 is close to the cleaning tank 13. This prevents the discharge mechanism 15 from blocking the wire mesh cage 40 on the temporary platform 4 when it comes into contact with the wire mesh cage 40, thus avoiding jamming. This structure enables the wire mesh cage 40 on the temporary platform 4 to be fed while the lifting platform 9 discharges the wire mesh cage 40, thereby meeting the requirements of high-efficiency continuous ultrasonic treatment.

[0053] Please see Figure 9A water outlet pipe 41 is installed below the rear end of the cleaning tank 13. A circulation pump 42 is installed on one side of the water outlet pipe 41, and a first valve 43 is installed on the other side of the water outlet pipe 41. A circulation pipe 46 is installed at the outer end of the water outlet pipe 41, and the upper end of the circulation pipe 46 is connected to the upper end of the rear end of the cleaning tank 13. A filter screen 47 is fixedly installed inside the circulation pipe 46. A rotating wheel 49 is installed at the middle position of the upper surface of the filter screen 47, and the rotating wheel 49 is connected to the filter screen 47 through a bearing. Brushes 50 are installed on both sides of the outside of the rotating wheel 49, and the lower end of the brushes 50 is in contact with the filter screen 47. A rotating shaft 48 is installed at the bottom of the rotating wheel 49, and the rotating shaft 48 is fixedly connected to the rotating wheel 49. An impeller 51 is fixedly installed at the lower end of the rotating shaft 48. A sewage pipe 44 is installed at the lower end of the circulation pipe 46, and the sewage pipe 44 is integrally formed with the circulation pipe 46. A second valve 45 is installed at the lower end of the outside of the sewage pipe 44.

[0054] During the ultrasonic treatment process, the second valve 45 is closed, and the circulation pump 42 and the first valve 43 are turned on. The cleaning solution inside the cleaning tank 13 is sent to the outlet pipe 41, and then from the outlet pipe 41 to the circulation pipe 46. During the movement of the circulation pipe, impurities inside the cleaning solution are blocked by the filter screen 47, thereby ensuring the purity of the cleaning solution and avoiding any impact on the workpiece processing. At the same time, when the water flows in the circulation pipe 46, it comes into contact with the impeller 51. Under the conversion of force, the impeller 51 rotates, and then drives the rotating wheel 49 to rotate through the rotating shaft 48, which drives the brush 50 to rotate at high speed. The brush 50 rotates and generates intense friction with the filter screen 47, thereby cleaning the residual dirt and preventing dirt and impurities from clogging the filter screen 47 and affecting the filtration effect. When the circulation pump 42 stops, the first valve is closed. The dirt inside the circulation pipe 46 gradually forms a precipitate under the action of gravity, and then enters the interior of the drain pipe 44. Finally, the staff only needs to open the second valve 45 to discharge the dirt inside.
