Ultrasonic cleaning machine for cleaning residues left after laser engraving of plastic casing of mobile phone

Abstract

The invention relates to an ultrasonic cleaning machine for cleaning residues left after laser engraving of a plastic casing of a mobile phone. The ultrasonic cleaning machine comprises a cleaning machine casing, a cleaning tank, a side piezoelectric transducer, a bottom piezoelectric transducer, a left-right direction ultrasonic generator, a front-back direction ultrasonic generator, an up-down direction ultrasonic generator, a liquid storage tank, a circulating pump, a filter, a heating pipe, a condensing pipe and a temperature controller; the cleaning tank is mounted and fixed in the cleaning machine casing; the cleaning tank comprises a bottom plate and four side plates, and the bottom plate is quadrangular, is not parallel to the horizontal plane and is inclined; the four side platesextend upward from the four edges of the bottom plate, and are not vertical but inclined; and the left-right direction ultrasonic generator and the front-back direction ultrasonic generator are connected with and control the side piezoelectric transducer, and the up-down direction ultrasonic generator is connected with and control the bottom piezoelectric transducer. According to the ultrasonic cleaning machine provided by the invention, ultrasonic sound pressure distribution is uniform during cleaning, standing waves are improved, the solution temperature is easy to control, and the cleaningeffect is good.

Description

technical field [0001] The invention relates to an ultrasonic cleaning machine, in particular to a cleaning machine for cleaning residues left after laser engraving of plastic casings of various mobile phones. Background technique [0002] After the laser engraving, the plastic casing of the mobile phone will leave residues. The cleaning machine used to clean these residues is an ultrasonic cleaning machine using a regular tetrahedral cleaning tank. [0003] In the known technology, the ultrasonic cleaning machine structure of the regular tetrahedral cleaning tank is: the bottom of the inner cavity of the cleaning machine tank is flat-bottomed, the four walls of the inner cavity are perpendicular to the bottom, and the cleaning machine tank has a regular tetrahedral structure. The ultrasonic piezoelectric transducer is installed on the bottom or the outside of the four walls of the regular tetrahedron washing machine tank, and the heating pipe is installed on the washing mac...
