Abstract

A self-rotation cleaning device has outer and inner housings, a workpiece rotating system, an ultrasonic cleaning system and a fluid perfusion system. The inner housing is in the outer housing in a horizontal direction. A cylindrical cavity is inside the inner housing. One end of the inner housing has a sealing cover detachably connected thereto, and the other end is closed. The workpiece rotating system is in the cavity for fixing a member to be cleaned, and realizes self-rotation of the member. The ultrasonic cleaning system supplies mechanical energy to the cleaning liquid in the inner housing to generate bubbles therein. The bubbles remove residual resin attached to the cleaned member surface by continuous vibration and burst. The fluid perfusion system provides self-rotation power for the cleaned member, and continuously delivers the cleaning liquid to the inside of the cleaned member, and the cleaning liquid is carried out after cleaning.
