Description

Technical Field

[0001] This invention relates to the field of ultrasonic cleaning technology, and more specifically to an ultrasonic cleaning machine. Background Technology

[0002] Oil stains, dust, metal shavings, and other impurities on the surface of workpieces can directly affect the subsequent assembly accuracy and product lifespan. Therefore, ultrasonic cleaning machines are needed to clean workpieces. Ultrasonic cleaning machines convert high-frequency electrical energy into mechanical vibrations through ultrasonic generators, which can efficiently remove contaminants from the surface and crevices of workpieces. Compared with traditional manual wiping and spray cleaning methods, it not only improves cleaning efficiency but also avoids scratches, deformation, and other damage to the workpiece surface. It is especially suitable for cleaning precision and complex structural workpieces.

[0003] For example, Chinese invention patent CN119909981B provides a tank-type ultrasonic cleaning machine device for cylinder processing. During the cleaning process, the device uses a blower pipe to continuously blow air, causing impurities and oil suspended on the liquid surface directly above the cylinder workpiece to collect on the inner wall of the cleaning tank on the side away from the blower pipe from the baffle. After the cylinder workpiece is cleaned, it will not carry any oil suspended on the liquid surface after being moved out of the liquid by the lifting plate. At the same time, when the lifting plate moves up to the top of the baffle, the cylinder workpiece on the support plate will lose the restraint of the baffle, resulting in an automatic unloading effect.

[0004] However, currently, ultrasonic cleaning of workpieces requires the use of multiple devices for cleaning and drying. As a result, workers need to transfer the workpieces between multiple devices, making it impossible to automatically switch between ultrasonic cleaning and drying functions. This increases the labor intensity of workers and reduces cleaning efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes an ultrasonic cleaning machine to solve the technical problem mentioned in the background art: currently, when ultrasonically cleaning workpieces, multiple devices are needed for cleaning and drying operations. This requires workers to transfer the workpieces between multiple devices, making it impossible to automatically switch between ultrasonic cleaning and drying functions, thus increasing the labor intensity of workers and reducing cleaning efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ultrasonic cleaner, comprising: The frame is equipped with the main body of the cleaning machine connected by a telescopic rod; A holding frame is detachably mounted on the frame, and the frame is also provided with a first driving mechanism for driving the holding frame to shake. The mounting bracket is slidably mounted on the frame, and multiple sets of drying heads are oscillatingly mounted on the mounting bracket. The mounting bracket is also provided with a second drive mechanism that drives the multiple sets of drying heads to oscillate back and forth. A linkage mechanism, disposed on the main body of the cleaning machine, converts the lifting and lowering of the main body of the cleaning machine into driving the mounting bracket to slide to one side of the holding frame; and A switching drive mechanism is mounted on the frame to selectively provide power to the first drive mechanism and the second drive mechanism after the main body of the cleaning machine is raised or lowered.

[0007] Furthermore, the first driving mechanism includes: A receiving base is provided on the frame, and the holding frame is detachably provided on the receiving base; A first connecting plate, rotatably mounted on the frame and connectable to the switching drive mechanism, can be driven to rotate by the switching drive mechanism after the main body of the cleaning machine is raised; and A first transmission component is disposed on the first connecting plate and connected to the receiving seat to convert the rotation of the first connecting plate into driving the receiving seat to sway.

[0008] Furthermore, the first transmission component includes: Two sets of rocker arms are provided, which are rotatably mounted on the frame and each of them is provided with a first drive column. The receiving seat is provided with a sliding groove. One set of the first drive columns is hinged to the receiving seat, and the other set of the first drive columns is slidably locked in the sliding groove. One set of the rocker arms is provided with a first gear. The second gear is rotatably mounted on the frame and meshes with the first gear; and The first synchronous belt mechanism is connected to the second gear and another set of rocker arms.

[0009] Furthermore, the linkage mechanism includes: The second drive column is disposed on the main body of the cleaning machine; and An inclined track is provided on the mounting bracket, and its end is connected to a first straight groove, in which the second drive column is slidably engaged.

[0010] Furthermore, the second drive mechanism includes: The mounting base is provided in multiple sets, all of which are swingably mounted on the mounting frame. The drying head is mounted on the mounting base, and the mounting base is also provided with a sliding frame. The drive frame is slidably mounted on the mounting frame and is provided with multiple sets of third drive columns, which are slidably engaged in multiple sets of sliding frames. The second connecting plate is rotatably mounted on the mounting bracket and can be connected to the switching drive mechanism. After the main body of the cleaning machine is lowered, the second connecting plate can be driven to rotate via the switching drive mechanism. The second transmission component is disposed on the second connecting plate and connected to the drive frame to convert the rotation of the second connecting plate into driving the drive frame to reciprocate.

[0011] Furthermore, the second transmission component includes: The drive disk is mounted on the second connecting disk; and The connecting rod is eccentrically hinged at one end to the drive disk and hinged at the other end to the drive frame.

[0012] Furthermore, the switching drive mechanism includes: The carriage is slidably mounted on the frame and is equipped with a drive motor. The third connecting plate is disposed on the output shaft of the drive motor and is engaged with the second connecting plate. A fourth connecting disc, rotatably mounted on the carriage, is connected to the third connecting disc via a second synchronous belt mechanism. The fourth connecting disc is in a disengaging connection with the first connecting disc. A switching component is mounted on the frame and connected to the carriage to convert the sliding of the main body of the cleaning machine into driving the carriage to slide.

[0013] Furthermore, the third connecting disc is connected to the second connecting disc by friction or by toothed connection; the fourth connecting disc is connected to the first connecting disc by friction or by toothed connection.

[0014] Furthermore, the switching component includes: The fourth drive column is disposed on the main body of the cleaning machine; and A straight track is arranged on the carriage, and both ends of the track are connected to parallel inclined grooves. When the main body of the cleaning machine is at its highest position, the fourth drive column is engaged at the top of the topmost set of inclined grooves.

[0015] Furthermore, the bottom of the inclined track is connected to a second straight groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In use, the workpiece to be cleaned is placed in a holding frame, which is then mounted on the frame. The lifting of the telescopic rod raises the main body of the cleaning machine, immersing the workpiece in the cleaning solution. The machine then performs ultrasonic cleaning. A first drive mechanism controls the holding frame to sway within the machine, dislodging impurities from the workpiece without manual agitation, thus improving cleaning efficiency. After cleaning, the machine body is lowered using the telescopic rod to remove the workpiece from the cleaning solution. During descent, a linkage mechanism controls the sliding of the mounting frame, allowing multiple sets of... The drying head moves to both sides of the holding frame and dries the workpiece by spraying gas from the drying head. Multiple sets of drying heads can be controlled to swing back and forth through the second drive mechanism to improve the drying effect. The switching drive mechanism provides power to the first drive mechanism and the second drive mechanism respectively after the main body of the cleaning machine is raised and lowered, without the need for additional control. This ensures that the movement of the holding frame and the movement of the drying head do not interfere with each other, so as to achieve the purpose of automatic cleaning and rapid drying. There is no need for the staff to transfer the workpiece between multiple devices. The ultrasonic cleaning function and the drying function are automatically switched, thereby effectively reducing the labor intensity of the staff and improving the cleaning efficiency.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0020] Example: like Figure 1 , 4 As shown in Figure 5, the present invention provides an ultrasonic cleaner, including a frame 1, a cleaner body 3 connected to the frame 1 by a telescopic rod 2, a detachable holding frame 7 on the frame 1, and a first driving mechanism for driving the holding frame 7 to shake on the frame 1. The first driving mechanism includes a receiving seat 6 on the frame 1, the holding frame 7 is detachably mounted on the receiving seat 6, and a first connecting plate 14 is rotatably mounted on the frame 1. The first connecting plate 14 is provided with a first transmission component connected to the receiving seat 6, and the rotation of the first connecting plate 14 by the first transmission component is converted into driving the receiving seat 6 to shake. The first transmission assembly includes two sets of rocker arms 9 rotatably mounted on the frame 1. Each rocker arm 9 has a first drive column 10 at its end. A slide groove 8 is provided on the receiving seat 6. One set of first drive columns 10 is hinged to the receiving seat 6, and the other set of first drive columns 10 is slidably locked in the slide groove 8. One set of rocker arms 9 is provided with a first gear 11, and a second gear 12 is rotatably mounted on the frame 1. The second gear 12 meshes with the first gear 11. The second gear 12 and the other set of rocker arms 9 are connected by a first synchronous belt mechanism 13.

[0021] In use, the device mounts the holding frame 7 containing the workpiece to be cleaned onto the receiving seat 6, and controls the telescopic rod 2 to rise, thereby raising the main body 3 of the cleaning machine and immersing the workpiece in the cleaning solution. The rotation of the first connecting plate 14 drives one set of rocker arms 9 and the first gear 11 above them to rotate. During rotation, the first gear 11 controls the rotation of the other set of rocker arms 9 via the second gear 12 and the first synchronous belt mechanism 13. The two sets of rocker arms 9 rotate in opposite directions. During rotation, one set of rocker arms 9 controls the movement of the receiving seat 6 and the holding frame 7 via the first drive column 10, causing the other set of first drive columns 10 to slide within the groove 8. This causes the holding frame 7 to sway in multiple directions within the ultrasonic cleaning machine, allowing impurities to quickly detach from the workpiece surface during ultrasonic cleaning, preventing impurities from remaining in the gaps of the workpiece and effectively improving cleaning efficiency.

[0022] like Figure 1 , 3 As shown, in this embodiment, a mounting frame 21 is slidably mounted on the frame 1. Multiple drying heads 23 are oscillatingly mounted on the mounting frame 21. A second drive mechanism is also provided on the mounting frame 21 to drive the multiple drying heads 23 to reciprocate. The second drive mechanism includes multiple oscillating mounting seats 22 mounted on the mounting frame 21. The drying heads 23 are mounted on the mounting seats 22. A sliding frame 24 is also provided on the mounting seats 22. A drive frame 25 is slidably mounted on the mounting frame 21. Multiple third drive columns 26 are provided on the drive frame 25. The multiple third drive columns 26 are slidably locked in the multiple sliding frames 24. A second connecting plate 29 is rotatably mounted on the mounting frame 21. A second transmission component connected to the drive frame 25 is provided on the second connecting plate 29. The rotation of the second connecting plate 29 through the second transmission component is converted into the reciprocating sliding of the drive frame 25. The second transmission assembly includes a drive disk 27 disposed on the second connecting disk 29, one end of the connecting rod 28 being eccentrically hinged to the drive disk 27, and the other end being hinged to the drive frame 25.

[0023] During the rotation of the second connecting plate 29, the drive plate 27 can be driven to rotate. During the rotation of the drive plate 27, the drive frame 25 can be controlled to slide back and forth on the mounting frame 21 through the arrangement of the connecting rod 28. This causes multiple sets of third drive columns 26 to slide back and forth in the slide frame 24. The cooperation between the third drive columns 26 and the slide frame 24 controls the mounting base 22 and the drying head 23 to swing back and forth. The drying head 23 sprays gas to dry the workpiece. The movement of the drying head 23 increases the contact area between the gas and the workpiece, reduces the drying dead corners, and avoids the cleaning liquid remaining in the gaps of the workpiece, effectively improving the drying effect.

[0024] like Figures 1 to 3As shown, in this embodiment, a linkage mechanism is provided on the main body 3 of the cleaning machine. The lifting and lowering of the main body 3 of the cleaning machine is converted into driving the mounting frame 21 to slide to one side of the holding frame 7 through the linkage mechanism. The linkage mechanism includes a second drive column 4 provided on the main body 3 of the cleaning machine. An inclined rail 30 is provided on the mounting frame 21. The end of the inclined rail 30 is connected to a first straight groove 31. The second drive column 4 is slidably locked in the first straight groove 31.

[0025] After the workpiece is cleaned by the main body 3 of the cleaning machine, the main body 3 of the cleaning machine can be lowered by controlling the extension rod 2 to retract. During the descent of the main body 3 of the cleaning machine, the second drive column 4 first slides in the first straight groove 31. At this time, the mounting frame 21 is not controlled to slide. When the main body 3 of the cleaning machine is lowered to the lowest point below the mounting frame 21, the second drive column 4 slides from the first straight groove 31 into the inclined track 30. The mounting frame 21 can then be controlled to slide by the cooperation of the second drive column 4 and the inclined track 30, so that multiple drying heads 23 move to one side of the holding frame 7 to dry the workpiece. There is no need for the staff to transfer the workpiece, which can effectively reduce the labor intensity of the staff when drying heavy workpieces.

[0026] like Figure 2 , 3 As shown in Figure 5, in this embodiment, a switching drive mechanism is provided on the frame 1. This switching drive mechanism selectively provides power to the first drive mechanism and the second drive mechanism after the main body 3 of the cleaning machine is raised or lowered. The first connecting plate 14 is connected to the switching drive mechanism and can be driven to rotate after the main body 3 of the cleaning machine is raised. The second connecting plate 29 is also connected to the switching drive mechanism and can be driven to rotate after the main body 3 of the cleaning machine is lowered. The switching drive mechanism includes a slide 15 that can slide laterally on the frame 1. A drive motor 17 is mounted on the slide 15. A third connecting plate 16, which is disengaged from the second connecting plate 29, and a fourth connecting plate 33, which is disengaged from the first connecting plate 14, are rotatably mounted on the slide 15. The fourth connecting plate 33 and the third connecting plate 16 are connected via a second synchronous belt mechanism 18. The output shaft of the drive motor 17 is connected to the third connecting plate 16.

[0027] The third connecting disk 16 can be rotated by controlling the drive motor 17. During the rotation of the third connecting disk 16, the fourth connecting disk 33 can be rotated by the second synchronous belt mechanism 18. The third connecting disk 16 and the second connecting disk 29 are connected by friction or by toothed connection. The fourth connecting disk 33 and the first connecting disk 14 are connected by friction or by toothed connection. This allows the third connecting disk 16 to control the rotation of the second connecting disk 29 when it is engaged with the second connecting disk 29, and the fourth connecting disk 33 to control the rotation of the first connecting disk 14 when it is engaged with the first connecting disk 14. It can be understood that in the toothed connection, multiple sets of teeth are arranged circumferentially on one side of the disk. When the two sets of disks are close, the teeth engage to achieve power transmission.

[0028] like Figure 2 , 3 As shown in Figure 5, in this embodiment, the switching drive mechanism further includes a switching component disposed on the frame 1 and connected to the slide 15. The switching component converts the sliding of the cleaning machine body 3 into the sliding of the drive slide 15. The switching component includes a fourth drive column 5 disposed on the cleaning machine body 3. A straight track 19 is arranged on the slide 15. Both ends of the straight track 19 are connected to parallel inclined grooves 20. When the cleaning machine body 3 is at its highest position, the fourth drive column 5 is engaged at the top of the top set of inclined grooves 20.

[0029] When the main body 3 of the washing machine is at its highest point, the fourth connecting plate 33 is engaged with the first connecting plate 14 to drive the holding frame 7 to shake. The third connecting plate 16 is separated from the second connecting plate 29. When the main body 3 of the washing machine is controlled to move down, the fourth drive column 5 slides in the topmost set of inclined grooves 20 to separate the fourth connecting plate 33 from the first connecting plate 14. When the fourth drive column 5 slides in the straight track 19, the second drive column 4 slides in the first straight groove 31 and the inclined track 30. The linkage mechanism controls multiple sets of drying heads 23 to move to one side of the holding frame 7. The bottom of the inclined track 30 is connected to the second straight groove 32. When the main body 3 of the washing machine continues to move down, the fourth drive column 5 slides in the bottom set of inclined grooves 20, and the second drive column 4 slides in the second straight groove 32. Thus, without controlling the sliding of the mounting bracket 21, the slide 15 can be controlled to slide again through the cooperation of the fourth drive column 5 and the bottom set of inclined grooves 20, so that the third connecting plate 16 engages with the second connecting plate 29 to control the reciprocating swing of multiple drying heads 23.

[0030] Specific usage and beneficial effects of the present invention: In use, the ultrasonic cleaner places the workpiece to be cleaned in the holding frame 7, which is then mounted on the frame 1. The extension rod 2 is raised to lift the main body 3 of the cleaner, immersing the workpiece in the cleaning solution within the holding frame 7. The main body 3 then performs ultrasonic cleaning on the workpiece. A first drive mechanism controls the holding frame 7 to sway within the main body 3, removing impurities from the workpiece without requiring manual agitation, thus improving cleaning efficiency. After cleaning, the extension rod 2 lowers the main body 3 to remove the workpiece from the cleaning solution. During the descent, a linkage mechanism controls the sliding of the mounting frame 21, allowing the workpiece to... Multiple drying heads 23 move to both sides of the holding frame 7, and the workpiece is dried by the gas sprayed from the drying heads 23. The multiple drying heads 23 can be controlled to swing back and forth by the second drive mechanism to improve the drying effect. The switching drive mechanism provides power to the first drive mechanism and the second drive mechanism respectively after the main body 3 of the cleaning machine is raised and lowered. No additional control is required, and the movement of the holding frame 7 and the movement of the drying heads 23 do not interfere with each other, so as to achieve the purpose of automatic cleaning and rapid drying. There is no need for the staff to transfer the workpiece between multiple devices. The ultrasonic cleaning function and the drying function are automatically switched, thereby effectively reducing the labor intensity of the staff and improving the cleaning efficiency.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
