AI Technical Summary

Technical Problem

The airtightness detection method of aluminum alloy battery tray in the prior art has low accuracy and cannot accurately locate the leakage position, especially for complex structures or large pallets.

Method used

An aluminum alloy battery tray leak test equipment is adopted. The tray is fixed by clamping the cylinder, and the airflow containing fluorescent liquid is used to fill the cavity under the action of the booster assembly. Combined with the detection mechanism and the opaque protection plate, the surface of the tray is observed for signs of fluorescent liquid leakage, and the scraper and connecting rod mechanism are used to clean the water mist to improve the detection accuracy.

Benefits of technology

High-precision airtightness detection of aluminum alloy battery trays is realized, which can accurately locate leakage points, reduce external light source interference, improve image quality, and enhance detection accuracy and visibility.

Abstract

The invention discloses leakage testing equipment for an aluminum alloy battery tray, and belongs to the technical field of air tightness detection of battery trays. Aluminum alloy battery tray leakage testing equipment comprises a rack, a table top for placing a tray is arranged in the rack, a ventilation shell is installed on the table top through a movable platform, a sealing plate is installed in the ventilation shell in a sliding mode, a scraping plate is arranged above the sealing plate, and a connecting rod mechanism is arranged between the sealing plate and the scraping plate. The pressurizing assembly is installed on the ventilation shell in a sliding mode, a mixing chamber is installed in the machine frame, a boss is arranged in the ventilation shell, and a connecting rod is fixedly connected between the boss and the sealing plate; the detection mechanism is installed on the inner top face of the rack through a movable platform, airflow containing fluorescent liquid is released through the pressurizing assembly and fills the whole cavity, along with pressure rising, whether the fluorescent liquid leaks out of the surface of the tray or not is observed through the detection mechanism, if a leakage point exists, a fluorescent mark appears at the position, and if not, the fluorescent liquid is detected. And identification and positioning are facilitated.
