Abstract

An automatic detecting device for air tightness of a battery comprises a stand, a battery fixture, a detector, a worktable, a rushing board, a water tank, an exhaust device and a controller. The stand is L-shaped; the battery fixture is arranged at the underframe of the stand; a running cylinder is arranged at the lower part of the battery fixture; a rushing board to push the battery is arranged on the outer side of the underframe of the stand; the rushing board is connected with the double-cylinder cylinder; an adjustable cylinder, which is connected with a slide bar, is arranged above the stand; the worktable is connected on the slide bar; and the worktable are provided with a plurality of detectors. As the device adopts the detector with a suction nozzle and an adhesive disc, the effective detecting range is extended, and a plurality of detectors detect at the same time and operate alternately with at least two pairs of batteries, thus greatly improving detecting efficiency and satisfying the requirement of industrial production. Besides, the device has the advantages of easy operation, prolonged detecting and observing time, and exact detecting result.

Description

technical field [0001] The invention relates to a battery air tightness detection device, in particular to an automatic battery air tightness detection device. Background technique [0002] During the battery manufacturing process, it is necessary to perform air tightness testing on the welded batteries to avoid leakage of the battery electrolyte due to poor welding. Most of the existing air-tightness detection methods are water tank-type manual detection methods. The air guide holes connected with the observation device are manually inserted into the liquid injection holes on the battery cover one by one, and the vacuum pump is used to reduce pressure to form a pressure difference. Vacuum the observation device. The air bubbles in the water container are used to judge the sealing performance of the battery welding joint. This air tightness detection method has low efficiency and low detection sensitivity, and the operation of inserting the air guide hole into the liquid in...
