[0002] Ultrasonic cleaning equipment utilizes the cavitation, acceleration, and linear flow effects of ultrasound in liquids to directly and indirectly clean liquids and contaminants. Widely used across a wide range of industrial sectors, ultrasonic cleaning equipment typically positions workpieces stationary within the cleaning chamber. This fixed position may prevent the workpiece from fully contacting the cleaning fluid, resulting in poor cleaning results in certain areas. This can also affect difficult-to-reach areas of complex structures and porous structures. Utility Model Content

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1-8 As shown, an ultrasonic cleaning device includes a housing 1, and a spray assembly 2 for spraying a workpiece is provided on one side of the inner wall of the housing 1;

[0028] A rotating drum 4 is rotatably mounted inside the outer shell 1 via several bearings 3. An ultrasonic transducer 401 and an ultrasonic generator 402 are provided inside the rotating drum 4. An outer gear ring 5 is rotatably mounted on one end of the rotating drum 4 via several support columns. A driving assembly 6 for driving the rotating drum 4 to rotate is provided on one side of the outer shell 1.

[0029] The spray assembly 2 includes a connecting column 201, which is fixedly mounted on one side of the inner wall of the housing 1. One end of the connecting column 201 extends into the interior of the drum 4. A water inlet pipe 202 is fixedly mounted on one end of the connecting column 201. One end of the water inlet pipe 202 extends into the interior of the drum 4 and is fixedly mounted with a first spray pipe 203.

[0030] A second spray pipe 204 is fixedly installed on the water inlet pipe 202 .

[0031] The driving assembly 6 includes a motor 601 , which is fixedly mounted on one side of the housing 1 . One end of the output shaft of the motor 601 extends into the interior of the housing 1 and is sleeved with a gear 602 , which meshes with the outer gear ring 5 .

[0032] The staff positions the workpiece inside the drum 4, and then starts the motor 601 so that its output shaft drives the gear 602 to rotate. Under the meshing action of the gear 602 and the outer gear ring 5, the drum 4 rotates back and forth at a certain angle, so that the workpiece inside the drum 4 rotates back and forth with it. Then the staff pours clean water into the water inlet pipe 202, and then starts the ultrasonic transducer 401 and the ultrasonic generator 402. The high-frequency sound waves are converted into mechanical energy through the ultrasonic transducer 401 and transmitted to the liquid, so that the clean water can fully clean the reciprocating workpiece, increase the cleaning range, and enhance the cleaning effect.

[0033] After cleaning is completed, the staff introduces air flow into the water inlet pipe 202, so that the first spray pipe 203 and the second spray pipe 204 spray gas to dry the workpiece.

[0034] In another embodiment of the present invention, a rotating frame 7 is rotatably mounted on the connecting column 201 , and a plurality of right-angle frames 8 are fixedly mounted between the rotating frame 7 and one side of the inner wall of the rotating drum 4 .

[0035] By providing the right-angle frame 8, it is possible to guide and limit the storage rack of the workpiece, and the staff does not need to use tools such as bolts to limit the workpiece, which saves time and effort.

[0036] In another embodiment of the present invention, a connection groove 9 is formed through the surface of each right-angle frame 8 close to the first spray pipe 203, and a plurality of rollers 10 are rotatably installed between the two sides of the inner wall of each connection groove 9.

[0037] By providing the rollers 10, the sliding friction generated when the workpiece moves along the right-angle frame 8 is converted into rolling friction, thereby avoiding excessive wear of the workpiece and the right-angle frame 8, which would affect the quality of the workpiece.

[0038] In another embodiment of the present invention, a plurality of positioning rollers 1001 are rotatably mounted on one end of the rotating drum 4 , and a positioning ring 11 is fixedly mounted on one side of the inner wall of the shell 1 , and the roller body of each positioning roller 1001 is in contact with the inner wall of the positioning ring 11 .

[0039] By arranging the positioning roller 1001 to fit the inner wall of the positioning ring 11 , the stability of the rotating drum 4 during operation can be increased to prevent it from deflecting or shaking.

[0040] In another embodiment of the present invention, a support base 12 is fixedly mounted on one side of the housing 1 , and a plurality of guide rollers 13 are rotatably mounted between two sides of the inner wall of the support base 12 .

[0041] By providing the support seat 12 and the guide roller 13 , it is convenient for the staff to control the workpiece to enter the housing 1 , and no manual movement is required, which further reduces the workload of the staff.

[0042] In another embodiment of the present invention, each guide roller 13 is commonly provided with a material rack 14, and positioning rails 15 are fixedly installed on both sides of the inner wall of the material rack 14. Two wire mesh clamps 16 are slidingly provided between adjacent positioning rails 15, and adjacent wire mesh clamps 16 are hingedly connected by hinges 17 respectively. A positioning block 1601 is fixedly installed on one side of the upper wire mesh clamp 16, and a positioning hole 18 is opened through one side of the positioning block 1601. A spring rod 19 is provided on one side of the lower wire mesh clamp 16, and the movable end of each spring rod 19 is respectively inserted and matched with the corresponding positioning hole 18.

[0043] By setting up a material rack 14 with a positioning track 15, it is convenient for the staff to quickly store the wire mesh clamp 16 containing the workpiece. The staff pulls the movable end of the spring rod 19 to disengage the movable end from the positioning hole 18. Under the action of the hinge 17, the staff can quickly open the adjacent wire mesh clamp 16, which is convenient for the staff to quickly take and place the workpiece, and convenient for the staff to quickly access the workpiece.

[0044] The working principle of this ultrasonic cleaning equipment:

[0045] During use, the staff positions the workpiece inside the drum 4, and then starts the motor 601 so that its output shaft drives the gear 602 to rotate. Under the meshing action of the gear 602 and the outer gear ring 5, the drum 4 rotates back and forth at a certain angle, so that the workpiece inside the drum 4 follows its reciprocating rotation. Then the staff pours clean water into the water inlet pipe 202, and then starts the ultrasonic transducer 401 and the ultrasonic generator 402. The high-frequency sound waves are converted into mechanical energy through the ultrasonic transducer 401 and transmitted to the liquid, so that the clean water can fully clean the reciprocating workpiece, increase the cleaning range, and enhance the cleaning effect.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
