Background

The battery cover cap is one of a plurality of components of the battery, and the battery cover cap plays the roles of sealing, a safety valve, a positive electrode conductive terminal and the like in the battery. The battery cap is because of various factors such as vibration dish transport drop, the outward appearance is impaired, the quality is bad in the manufacturing process, some battery cap can appear the defect such as gas pocket damage, if install these block that have the gas pocket defect on the battery, the later stage will lead to the battery can not normally seal electrolyte, has the risk such as weeping, impurity entering battery, influences the battery quality, for this reason the gas tightness of battery cap detects very necessarily, and does not have the device that detects specially to battery cap gas tightness in the battery market now.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned defect that exists of prior art, the utility model provides a battery cap gas leakage detection device, concrete technical scheme is as follows:

the utility model provides a battery cap gas leakage detection device, which comprises a jig, detect the head, the pipe connection, the trachea, the pressure measurement table, the fixed plate, elevator and lift actuating mechanism, the tool is equipped with the recess that is used for placing the battery cap, it is located directly over the recess to detect the head, it communicates trachea one end to detect the head through the pipe connection, trachea other end intercommunication pressure measurement table, the pressure measurement table, lift actuating mechanism installs in the fixed plate, it installs in the elevator bottom to detect the head, lift actuating mechanism drive elevator reciprocates and goes up and down, the elevator drives and detects the head and descend to compress tightly the battery cap or rise and leave the recess in getting into the recess.

As a preferred scheme of the utility model, lift actuating mechanism includes cylinder, slider and slide rail, and the cylinder piston rod is connected the elevator top, elevator back installation slider, slider sliding connection slide rail, the vertical installation in fixed plate of slide rail.

As a preferred scheme of the utility model, it is equipped with the detection cavity and inside detection channel that is equipped with to detect the head bottom, detects cavity contact battery cap surface when detecting the head and compressing tightly the battery cap, detects the cavity and communicates with each other with detection channel, and detection channel passes through the pipe connection intercommunication trachea.

As an optimized proposal of the utility model, the jig has a plurality of circular arrays arranged on the turntable.

Has the advantages that: the utility model discloses battery block gas leakage detection device is at the during operation, the battery block is placed in the recess of tool, lift actuating mechanism drive elevator descends, the elevator drives and detects the head decline and compresses tightly the battery block in getting into the recess, because it passes through trachea intercommunication pressure detection table to detect the head, when outside air supply supplies gas through the pressure detection table and reachs the battery block, if the pressure display numerical value of pressure detection table takes place the major change, then show that the battery block has the aperture damage to take place gas leakage, thereby judge whether qualified battery block quality, guarantee the product quality.
