Description
Technical field
The present invention relates to battery sealing-performance detection field, particularly relate to a kind of lithium battery apparatus for testing weeping.
Background technology
Lithium battery has the advantages such as voltage is high, specific energy is high, recycle often, storage time is long, not only on a portable electronic device as mobile phone, Digital Video and laptop computer are used widely, and be widely used in the big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool.The environment of lithium battery interior working environment and outside batteries must be completely isolated, ensures the normal work of battery, and technically realized by modes such as welding or colloid sealings, the quality of sealing directly determines that can battery normally work.
If cell sealing goes wrong, internal and external environment is caused to communicate, the electrolytic solution of inside battery, gas etc. can be made to leak and cause serious safety problem, in addition, the air in environment, moisture etc. also can enter battery and participate in the forfeiture that electrochemical reaction causes battery failure charging/discharging function.Therefore, in the production run of lithium battery, sampling leak detection must be carried out to its housing, prevent from streamline occurring the large batch of battery container having leakage.
Publication number is in the patent documentation of 201876343U, disclose a kind of lithium ion battery leakage detecting device, comprise the casing holding lithium ion battery to be measured, the top of casing is with gas outlet, position, gas outlet is covered with inverted funnel, be provided with organic compound component detector, the detection head of this organic compound component detector is positioned at the opening part of described funnel, this device is mainly through heating and the method increasing air circulation, promote the volatilization spilling electrolyte organic components, be conducive to the judgement of gas composition content; Adopt photoionization organic compound volatile content detector to detect constituent of air organic content near battery, and environmentally condition sets detection alarm value, to battery, whether leakage judges.If leakage does not occur battery, tester display numerical value is less than the reference value of environmentally condition setting, if there is battery generation leakage, tester display numerical value is greater than reference value, instrument alarm.But this leak detection mode complicated operation, time-consuming, need to use comparatively accurate, expensive helium mass spectrometer leak detector, leak detection cost is high.
Publication number is in the patent documentation of 203940962U, disclose a kind of lithium battery casing leakage detection apparatus, the leakage battery container to be checked comprising inflation inlet, connecting cylinder and be with holes, the inside surface at the two ends of connecting cylinder is provided with O-ring seal, inflation inlet is connected with the side of connecting cylinder, in the connecting cylinder described in leakage battery container to be checked inserts.Wherein, the length of connecting cylinder is less than the length of leakage battery container to be checked, and during detection, electric leakage pond to be checked shell end is exposed at outside cylinder, coating leak detection liquid in end and inflate in inflation inlet, whether occurring that bubble judges the quality of sealing by observing the end leakage battery container to be checked scribbling leak detection liquid.But electric leakage pond to be checked shell end is difficult to retention and hunts leak in a large number liquid, this will cause the hunt leak liquid level of liquid of end excessively thin, and when inflation inlet passes into gas, whether the leak detection liquid liquid level of battery end has bubble formation to be difficult to see clearly, thus the accuracy that impact judges; In use, the leakproofness of O-ring seal is difficult to be guaranteed, even if there is the situation that O-ring seal sealing effectiveness is bad, user is also difficult to find, institute's qi of chong channel ascending adversely body will be caused directly to be overflowed by the slot of device and do not reach Detection results.
Therefore, how can improve existing lithium battery apparatus for testing weeping, be that those skilled in the art have technical barrier to be solved.
Summary of the invention
The invention provides a kind of lithium battery apparatus for testing weeping, easy to use, can judgment means impermeability, detection accuracy is high, and to have structure simple simultaneously, the advantages such as cost is low.
