Ultrasonic cleaning device of power battery aluminum shell

Abstract

The invention discloses an ultrasonic cleaning device of a power battery aluminum shell. The ultrasonic cleaning device comprises a cleaning mechanism, wherein the two opposite side walls of the cleaning mechanism are provided with first ultrasonic transduction elements which launch ultrasonic signals to each other, a plurality of second ultrasonic transduction elements are arranged on the bottomwall of a cleaning container, and the first ultrasonic transduction elements and the second ultrasonic transduction elements are different in ultrasonic frequency; and the first ultrasonic transduction elements and the second ultrasonic transduction elements are same in structure and both comprise bodies and heating pipes, wherein the bodies comprise front cover plates, rear cover plates and flanges which are connected in sequence, the bodies are wrapped around piezoelectric ceramic elements, and the heating pipes are fixedly inserted into the bodies through the flanges. In the working process, uniformly distributed reverberant sound fields are formed in the cleaning container, so that no blind cleaning area exists, and due to the fact that the piezoelectric ceramic elements are wrapped inthe bodies, the problem that the piezoelectric property of piezoelectric ceramics of heating parts is invalid due to the fact that an existing ultrasonic cleaning machine has cleaning blind areas andthe heat dissipation effect of a fan is poor is solved.

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...
