Since the notch 1215 is located at the end surface 121 At the front end, the cleaning solvent 500 discharged through the notch 1215 first reaches the cleaning object 200 to soften the impurities 400. The softening time is increased, and the impurity removal rate of the ultrasonic cleaning machine 100 is further improved.

It can be understood that when the ultrasonic cleaning machine 100 is cleaning, the ultrasonic cleaning machine 100 moves relative to the cleaning object 200 in the first direction, and the orientation of the notch 1215 is the same as the first direction or deviates from the first direction by less than 90 degrees.

The edge of the sub-end surface 1210 at least partially overlaps the edge of the end surface 121 of the second end portion 12 and forms a partial edge of the notch 1215. In this embodiment, the end surface 121 is substantially circular, and the radius of the end surface 121 is D. The sub-end surface 1210 is circular, and the radius of the sub-end surface 1210 is d, where d is smaller than D. The suction area 1213 is provided around the sub-end face 120.

Please refer to FIG. 3, which is a schematic diagram of the area distribution of the end surface 121 of the second end 12 of the frame of the ultrasonic cleaning machine according to an embodiment of the present invention. The end surface 121 is substantially rectangular, and the length of the long side of the end surface 121 is D. The sub-end surface 1210 is substantially rectangular, and the length of the long side of the sub-end surface 1210 is d, where d is smaller than D. One long side of the sub-end surface 1210 overlaps with a long side of the end surface 121. The notch 1215 is adjacent to the edge of the end surface 121 and the edge of the sub-end surface 1210. That is, the notch 1215 is located at a position where the outer peripheral edge of the sub-end surface 1210 partially overlaps the outer peripheral edge of the second end portion 12, and the notch 1215 extends along the outer peripheral edge of the sub-end surface 1210.

It can be understood that the shape of the end surface 121 is not limited to circular and rectangular, and the shape of the end surface 121 may also be other shapes; the shape of the sub-end surface 1210 is not limited to circular and rectangular, and the shape of the sub-end surface 1210 may also be other shapes. For example, please refer to FIG. 4, which is a schematic diagram of the area distribution of the end surface 121 of the second end 12 of the frame of the ultrasonic cleaning machine according to an embodiment.

In addition, by providing a notch 1215 on the end surface 121 of the second end portion 12 of the frame 10, the notch 1215 is disposed adjacent to the edge of the end surface 121 of the second end portion 12 and the edge of the sub-end surface 1210. The compressed air flow carrying the cleaning solvent 500 is less affected by the vacuum suction part 50, so that the compressed air flow carrying the cleaning solvent 500 discharged from the notch 1215 has a greater impact force, and it is easier to remove impurities adhering to the surface of the cleaning object 200 , Thereby improving the impurity removal rate of the ultrasonic cleaning machine 100. Further, when the ultrasonic cleaning machine 100 is cleaning, the notch 1215 is located at the front end of the end surface 121, because the notch 1215 is located at the front end of the end surface 121, that is, the portion where the cleaning object 200 first arrives along the conveying direction of the conveying device, passes the notch The cleaning solvent discharged at 1215 first reaches the cleaning object 200 to soften the impurities 400. As the softening time is increased, the impurity removal rate is further improved.
