Abstract
The utility model relates to a battery leakage detecting device. The battery leakage detecting device comprises a main tooling body composed of a lower housing and a cover plate. The main tooling body is internally provided with a high-pressure cavity used for accommodating a detected battery. The detected battery is fixed in the high-pressure cavity of the main tooling body. The lower housing and the cover plate are respectively provided with an opening communicated with the high-pressure cavity, and the positions of the openings right face the detected battery in the high-pressure cavity. The battery leakage detecting device further comprises an air nozzle arranged on one side of the lower housing, and the air nozzle is provided with an air inlet channel communicated with the high-pressure cavity. Compared with the prior art, the battery leakage detecting device is capable of carrying out leakage detection on a lithium ion battery, so that the yield of the battery production is improved, and the safety risks in the using process of a user are eliminated.
Description
Technical field
The utility model relates to a kind of battery detection equipment, specifically a kind of battery drain pick-up unit.
Background technology
Aluminum current plastic film soft bag lithium ionic cell is in processing procedure process; often can there is the situation of leaking; but never have at present effective and reliable equipment, it is detected, thereby in the hand that causes having a lot of defective productss to flow into user, make user in use have potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of battery detection equipment, can carry out leak detection to lithium ion battery, thereby the yields while having improved battery production is eliminated user's potential safety hazard in use.
To achieve these goals, the utility model provides a kind of battery drain pick-up unit, comprise the frock main body being made up of lower casing and cover plate, be formed for placing the high-pressure chamber of tested battery in described frock main body, described tested battery is fixed in the high-pressure chamber of described frock main body;
Described lower casing and described cover plate have respectively an opening being communicated with described high-pressure chamber, and the position of described opening is right against the tested battery being arranged in described high-pressure chamber;
Described battery leakage pick-up unit also comprises: be arranged on the valve of described lower casing one side, described valve has an inlet channel being communicated with described high-pressure chamber.
Embodiment of the present utility model in terms of existing technologies, in the time that reality detects, gases at high pressure are passed into by the inlet channel of valve (general 0.3-0.6Mpa pressure-air) in the high-pressure chamber of frock main body, if tested battery has leakage path in high-pressure chamber, gases at high pressure will enter tested inside battery by this passage, the normal pressure cavity of tested battery is because inside and outside differential pressure can show raised position, staff can observe directly by the opening on lower casing and cover plate, if tested battery does not have leakage path, there will not be protruding phenomenon, complete the Leak Detection of battery with this.
Preferably, described cover plate and described lower casing adopt screw to be fixed connection.
Preferably, be provided with the first sealing ring and the second sealing ring in described high-pressure chamber, described the first and second sealing rings are separately positioned on the lower surface of described cover plate and the upper surface of described lower casing; Described tested battery be directly fixed on described first and described the second sealing ring between.Can strengthen tested battery by two groups of sealing rings and be fixed on the sealing property in high-pressure chamber, thereby avoid gases at high pressure to reveal from high pressure chest.
In order to meet the demand in market, described the first and second sealing rings are metallic packing ring, rubber seal ring or plastic cement sealing ring.Staff can select according to actual user demand.
Brief description of the drawings
