Description
Technical field
Lithium battery electric core detection technique field is the utility model is related to, it particularly relates to which a kind of lithium battery electric core is forced
Interior short sample preparation glove box.
Background technology
Required according to the coherent detection of lithium battery electric core, for the battery core of lithium battery, to carry out forcing internal short-circuit test,
For verifying that product design whether there is defect.And the environment of the sample preparation of the battery core for forcing internal short-circuit, has bright
Really require, that is, require to require according to standard, in the Embedded test sample the nickel sheet of specific dimensions, but environment needs to meet temperature
20 °C ± 5 °C and requirement of the dewpoint less than -25 °C.
On the one hand：Presently commercially available prepares case, is substantially the support member of fixed dimension, for sample system short in pressure
Standby, due to the particularity of its operation, its operating time is typically in the 3-4 small times, that is, needs operator to be always maintained at both hands
In glove box, operation of bowing.Because the height of operator is not quite similar, so, fixed height is for different operators
Member, it is very easy to cause the fatigue of operator；In addition, the current case for preparing much all takes common incandescent lamp tube, only it is general
Logical illuminating effect, but not it is considered that the long-term high concentration of operator visually prepares sample, it is easy to cause operator's
Visual fatigue, so as to influence the accuracy and operating efficiency of operation；Secondly, presently commercially available prepares case, provide only metal or
Acrylic casing, and sealed and vacuum extractor, and sample preparation operations are carried out by rubber gloves, but in actual behaviour
During work, except soft pack cell, it is easier to disassemble, for square aluminum hull battery core, 18650 and 18550 cylindrical battery cores,
Because during disassembling, it is necessary first to take the metal shell of battery core apart, but because rubber gloves is thicker, so, disassembling
Cheng Zhong, it is difficult to wear gloves to hold battery core, accurately operated, not only need operator to have enough strength, moreover, once
Careless manipulation, it is easy to cause the short circuit of sample, add preparation difficulty and the time of sample.
On the other hand, in Sample Preparation Procedure, inert gas is substantially filled with casing, in this environment, if sample
There occurs the situation of short circuit, due to the characteristic of inert gas, serious risk on fire, but actual mechanical process will not also occur for product
In, the gloves of operator, accidentally scratched or by the possibility of sharp knife blade or existing by the metal-back of battery core, but hand
Small breakage is covered, is not easy to be found in time, but the breakage of gloves, easily cause the oxygen of outside to enter in casing, into
For short circuit when combustion adjuvant, so as to cause risk on fire；Secondly, during battery is disassembled, if the problems such as casing is due to aging,
Cause it is poorly sealed, or partial oxidation enter casing in, once occur short circuit situation, sample heating can be caused first, by
Rubber gloves operation is had in operator, can't be very sensitive for the actual temperature feedback of sample, but when once find,
Temperature caused by short circuit is very high, and now, the probability caused danger can increase.
Finally, it is commercially available to prepare case, small sample transfer chamber is much equipped with, in order to taking for sample, but due to behaviour
Author is unskilled or accidental cause, it may occur that and inside cabin is not yet closed, or is not turned off tight, turns on the situation of transfer chamber,
At this moment, overall experimental situation is just destroyed, have impact on the preparation process of whole sample.
