Automatic air impermeability helium detector for square power batteries

Abstract

The invention discloses an automatic air impermeability helium detector for square power batteries. The automatic air impermeability helium detector can automatically complete on-line leakage detection of aluminum-shell battery cores, is high in efficient and avoids direct contact between the human hand and the aluminum-shell battery cores. The automatic air impermeability helium detector comprises a machine frame. The machine frame is provided with a feeding pull belt assembly, a helium detection testing assembly and a feeding and discharging mechanical arm assembly. The feeding and discharging mechanical arm assembly comprises a feeding mechanical arm assembly and a discharging mechanical arm assembly, wherein the feeding mechanical arm assembly and the discharging mechanical arm assembly are arranged in a back-to-back mode. The feeding pull belt assembly comprises an aluminum-shell battery core feeding position at the start end, an aluminum-shell battery core discharging position at the tail end and an aluminum-shell battery core detection position between the feeding position and the discharging position. The machine frame is further provided with a helium injection assembly connected with a helium injection port of the helium detection testing assembly, and a vacuumizing pipeline assembly connected with a vacuumizing port of the helium detection testing assembly. The vacuumizing pipeline assembly is connected with a vacuum pump assembly. The machine frame is further provided with a helium detection instrument.

Description

technical field [0001] The invention relates to a leak detection device for a square power battery, in particular to a leak detection device using helium gas. Background technique [0002] In the production process of prismatic power batteries, aluminum shell batteries need to undergo a leak detection process. The traditional leak detection process cannot achieve online detection well, and it is necessary to manually carry out multiple aluminum shell battery transfer processes; the transfer process is mainly It is used to take the aluminum shell cells from the logistics pull line (main production line), to put the aluminum shell cells into the helium detector, and to put the tested aluminum shell cells into the logistics pull line; the efficiency of the whole process is low , At the same time, it also makes manual direct contact with aluminum shell cells, which is easy to pollute and causes unstable production quality.
