Description

TECHNICAL FIELD

[0001] The utility model relates to dust removal equipment technical field, concretely is a kind of ultrasonic suspension dust removal device. BACKGROUND

[0002] With the sustained and rapid development of new energy vehicle industry, the requirements for battery capacity, performance and stability are higher. Composite current collector is one of indispensable electrode materials of lithium ion battery, and its main function is to conduct electricity. The composite current collector not only serves as a carrier for positive and negative active materials, but also serves as a positive and negative electrode electron collection and conduction body. Its function is to collect the current generated by the battery active material to generate greater output current. The composite current collector has high electrical conductivity, good stability, good mechanical strength, low cost and other comprehensive properties. During the production of the composite current collector, cutting is required, which will inevitably produce conductive powder, and burrs will also exist in the cutout. The cutout dust has static electricity, which is difficult to remove by simple negative pressure adsorption, seriously affecting the quality of lithium battery finished products.

[0003] A kind of ultrasonic suspension surface treatment device is disclosed in Chinese invention patent with application publication number CN102496695A, which includes an ultrasonic powder cleaning mold, and the ultrasonic powder cleaning mold is connected to an ultrasonic transducer through a fixing seat at least at one end. The ultrasonic powder cleaning mold includes at least one long and narrow powder cleaning through hole opened along the longitudinal direction of the ultrasonic powder cleaning mold and a negative pressure exhaust hole communicating with the powder cleaning through hole. The negative pressure exhaust hole and the powder cleaning through hole are vertically arranged. Although the surface of the thin sheet-shaped lithium battery electrode material and the cutout position can be effectively treated, the pollutants on the surface of the coated battery material and the burrs on the cutout position can be completely removed, ensuring the quality and reliability of the lithium battery. However, the above structure is relatively complex, the ultrasonic efficiency is low, and the dust removal and powder cleaning effect needs to be improved. UTILITY MODEL CONTENTS
