Ultrasonic cleaning device for power battery aluminum shell

Abstract

The invention discloses an ultrasonic cleaning device for an aluminum shell of a power battery, which includes a cleaning mechanism, and a first ultrasonic transducer element for mutual emission of ultrasonic signals is arranged on the opposite side walls of the cleaning mechanism, and a first ultrasonic transducer element is arranged on the cleaning container The bottom wall is provided with several second ultrasonic transducer elements, and the ultrasonic frequencies of the first ultrasonic transducer element and the second ultrasonic transducer element are different; the first ultrasonic transducer element is different from the second ultrasonic transducer element The elements have the same structure, and they all include a body and a heat pipe. The body includes a front cover, a rear cover, and a flange connected in sequence. The body wraps the piezoelectric ceramic element, and the heat pipe is fixed and inserted in the within the body. When working, an evenly distributed reverberation sound field is formed in the cleaning container, so that there is no blind area in the cleaning, and because the piezoelectric ceramic element is wrapped, it solves the existing cleaning blind area of ​​the existing ultrasonic cleaning machine and the heating caused by the poor cooling effect of the fan The problem of failure of piezoelectric properties of component piezoelectric ceramics.

Description

technical field [0001] The invention belongs to the technical field of power lithium battery production, and in particular relates to an ultrasonic cleaning device for a power battery aluminum case. Background technique [0002] As a new type of functional battery, power lithium battery has the advantages of high energy, high battery voltage, wide operating temperature range, and long storage life. It has been widely used in military and civilian small electrical appliances. [0003] Among them, square lithium batteries are used as the power source of new energy vehicles, and their shipments are increasing. The casing of the prismatic lithium battery is usually an aluminum casing. After the aluminum casing is punched and formed by a machine tool, a lot of oil stains and sundries will adhere to the surface, so it needs to be cleaned. The existing technology is to use the unique cavitation effect of ultrasound in the solution to wash away the stains on the surface of the shel...
