New energy battery case cleaning technology

Abstract

The invention discloses a new energy battery case cleaning technology. The new energy battery case cleaning technology sequentially comprises the cleaning working procedures of the first time of water base cleaning, the second time of water base cleaning, the third time of water base cleaning, the first time of water draining cleaning, the first time of ultrasonic saponification, the second time of water draining cleaning, the first time of ultrasonic hydrocarbon cleaning, the second time of ultrasonic hydrocarbon cleaning, the first time of vacuum bathing and drying, and the second time of vacuum bathing and drying, wherein a distillation recovery working procedure is arranged between the first time of ultrasonic hydrocarbon cleaning and the second time of ultrasonic hydrocarbon cleaning, a leaching recovery working procedure is arranged between the first time of water base cleaning and the second time of water base cleaning, and a leaching recovery working procedure is arranged between the second time of water base cleaning and the third time of water base cleaning. According to the new energy battery case cleaning technology, precleaning is carried out through the action of emulsification, permeation, cleaning and the like of surfactants, then metathesis is carried out with a hydrocarbon water draining agent, water draining is carried out after ultrasonic saponification is carried out, and at last, strengthened cleaning is carried out with a vacuum hydrocarbon cleaning agent so that dirt on a highlight surface can be thoroughly removed. The new energy battery case cleaning technology is good and stable in quality, and furthermore, the cleaning agent is recyclable, the cost is low, and the influence on the environment is little.

Description

technical field [0001] The invention relates to the field of workpiece surface cleaning, in particular to a new energy battery case cleaning process. Background technique [0002] The pollutants on the aluminum shell or stainless steel shell of the new energy battery are mainly zinc stearate, lifting oil, etc., while the traditional cleaning method is solvent ultrasonic cleaning-solvent ultrasonic cleaning-solvent ultrasonic cleaning-drying, and the solvent used It is trichlorethylene or tetrachlorethylene. The principle is to achieve the purpose of cleaning through the similar compatibility of solvents. However, after this traditional cleaning method, the cleaning quality of the aluminum or stainless steel shell of the new energy battery is unstable and prone to cleaning. Incomplete, such as incomplete removal of oxidized macula, black dust, powder stain residue, etc., the defect rate is about 7-10%, which greatly affects the subsequent processing of the aluminum or stainle...
