All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-4 The present invention provides a technical solution: an ultrasonic cleaning machine and its spraying system, comprising a frame 1, a cleaning tank 2, an auxiliary washing mechanism, and a spraying system.

The slide plate 43 is movably arranged between the slide rails 41. The hanging rods 44 are spaced on the slide plate 43 and have hooks 441 on the left and right sides. The feeding plate 45 is fixed to the front end of the slide rail 41 and is arranged in accordance with the position of each hanging rod 44. The material tray 46 is arranged at the bottom of the slide rail 41.

[0032] The hook 441 is made of elastic material. The holes of the stamped parts are hung on the hook 441 so that each stamped part hangs naturally, avoiding overlapping and making the surface of the part to be cleaned completely exposed.

[0034] The surface of the tray 46 is designed with a grid structure to prevent cleaning water and dirt from accumulating on its surface.

[0035] In actual operation, after the ultrasonic cleaning of the stamped parts is completed, the lifting assembly 3 lifts the loading and unloading assembly 4 to prepare for unloading. During the lifting process, when each hook 441 contacts the unloading part 452, it bends under the influence of downward pressure, and the stamped parts lose support and fall onto the material tray 46. Finally, the stamped parts in the material tray 46 are transferred to the spray system for post-processing.

[0036] The lifting assembly 3 includes a fixed frame 31, a connecting frame 32, and a second cylinder 33, wherein the second cylinder 33 is fixed on the fixed frame 31 and the drive end is connected to the connecting frame 32. The connecting frame 32 is used to fix the loading and unloading assembly 4.

[0037] The cleaning tank 2 includes a housing 21, an ultrasonic generator 22, and a water tank 23. The housing 21 is configured with an inner and outer layer structure. The inner housing is used for cleaning operations, and the ultrasonic generator 22 is located at the bottom of the inner housing. The outer housing is used to protect the internal structure.

The liquid cutting assemblies 6 and spraying assemblies 7 are staggered on both sides of the conveying assembly 5. The drying assembly 8 is located at the outlet of the last set of liquid cutting assemblies 6. The liquid cutting assemblies 6 are used to remove cleaning liquid from the upper and lower surfaces of the stamped parts. The spraying assemblies 7 are used to wash the stamped parts with clean water. The drying assembly 8 is used for the final drying of the stamped parts before they are discharged.

[0044] S1. Feeding: The operator hangs the stamped part on the hanging rod 44;

[0045] S2, Ultrasonic Cleaning: Enter cleaning solution of appropriate temperature into cleaning tank 2, and start ultrasonic generator 22 to begin cleaning operation;

[0046] S3. Transfer: After ultrasonic cleaning, the loading and unloading assembly 4 lifts the entire stamped part and transfers each stamped part to the material tray 46, and finally transfers it to the spray system for post-processing.

[0047] S4. Post-processing: After ultrasonic cleaning, the stamped parts will undergo multiple processes of liquid cutting and spraying to completely remove the surface cleaning liquid before drying and unloading.

[0048] S41, Liquid Removal: High-pressure gas is delivered to the surface of the workpiece through an air knife to remove the liquid on the surface of the workpiece, achieving a rapid drying effect. The cleaning object in this case is a thin sheet stamped part. During conveying, the workpiece is laid flat on the conveyor belt at intervals. The conveyor belt adopts a mesh structure to ensure vertical continuity. The air outlet of the first air knife 61 is set at an angle to the input direction. Under the force applied by the first air knife 61 on both the upper and lower sides, the workpiece will shift in the opposite direction to the input direction, so that the bottom part that is covered can be exposed and thus fully dried.

[0049] S42, Spraying: The water outlet of the spray head 71 is tilted in the input direction. Under the force applied by the upper and lower spray heads 71, the workpiece will shift in the opposite direction of the input direction, so that the bottom part that is covered can be exposed and thus thoroughly cleaned.

[0050] S43. Drying: The air outlet of the second air knife 82 is set at an angle to the input direction. Under the force applied by the second air knife 82 on both the upper and lower sides, the workpiece will shift in the opposite direction to the input direction, so that the part that is covered at the bottom can be exposed and thus fully dried.

[0051] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
