Description
Technical field
This utility model is related to lithium battery detection device field, particularly to a kind of lithium battery encapsulation damage detection device.
Background technology
Existing aluminum plastic film product, is mainly prepared into the external package casing of lithium ion battery, if the performance of aluminum plastic film is not
Good, such as rushing hole has slight crack, package position to have stripping or aluminum plastic film crooked place to have bubble, all can have a strong impact on the safety of battery
Performance.
The a lot of type of method for testing performance of existing aluminum plastic film, the main purpose of test is to detect that the stretching of aluminum plastic film is strong
Degree, shock resistance, the performance such as tensile strength of encapsulation post package, can be reached with determining that aluminum plastic film is prepared into the performance detection of battery
To nation's security standard.But these detection methods need the detection cycle grown very much, detection efficiency is low, the life of impact lithium battery
Produce.
Utility model content
This utility model is directed to the disappearance of prior art presence, provides a kind of lithium battery encapsulation damage detection device, this inspection
Survey the simple structure of device, accurate testing result can be obtained in the short period of time.
For achieving the above object, this utility model is using as purgation technical scheme：
A kind of lithium battery encapsulation damage detection device, including thermostatic water tank and make the water in thermostatic water tank be maintained at 40 DEG C-
50 DEG C of temperature control system, described thermostatic water tank side offers observation window, and being provided with described thermostatic water tank can be by lithium battery to be measured
The deionized water being totally submerged, described temperature control system includes temperature sensor, heater, heating water tank and control panel, institute
State temperature sensor in thermostatic water tank, described heater in heating water tank, described thermostatic water tank and heating water tank
Between connected by water service pipe, described control panel and temperature sensor and heater communication are connected, and foundation temperature sensing
The temperature information of device transmission controls the break-make of heater.
As a kind of preferred version, described heater is electrothermal tube.
As a kind of preferred version, described control panel is provided with the display screen for showing water temperature in thermostatic water tank.
During detection, heater begins to warm up the deionized water in heating water tank, and the deionized water after heating is through water service pipe
With the mutual convection current heat of the deionized water in thermostatic water tank, the temperature sensor in thermostatic water tank detects thermostatic water tank
When 40 DEG C -50 DEG C, control panel controls heater stop heating to interior water temperature, and controls the water temperature in thermostatic water tank always
In 40 DEG C -50 DEG C, now, lithium battery to be measured is put in the deionized water of thermostatic water tank and soak, and pass through daily to see
The aluminum plastic film examining window observation lithium battery occurs either with or without the phenomenons such as tympanites, bubble, layering.If the aluminum plastic film of lithium battery occurs
The phenomenons such as tympanites, bubble, layering, then represent lithium battery is packaged with breakage, if tympanites, gas in the aluminum plastic film of lithium battery
The phenomenons such as bubble, layering, then the encapsulation representing lithium battery does not have breakage.
This utility model compared with prior art, has advantages below and advantage, specifically：1st, pass through to arrange thermostatted water
Case, and lithium battery to be measured is soaked in the deionized water in thermostatic water tank, so, lithium battery is in soaked such harshness
Under the conditions of, once aluminum plastic film has breakage, then the phenomenons such as tympanites, bubble, layering occurs, so just can be in shorter detection
More accurate testing result is obtained in cycle；2nd, the structure of this detection means is simple, low manufacture cost；3rd, because this detection fills
It is equiped with temperature control system in putting, be easy to control temperature conditionss during detection lithium battery, improve the accuracy of testing result further；
4th, detect after deionized water can Recycling, environmental protection.
For more clearly illustrating architectural feature of the present utility model, technological means and its specific purposes being reached and work(
Can, come with specific embodiment below in conjunction with the accompanying drawings this utility model is described in further detail：
