Embodiment
The application is described in further detail below by specific embodiment and with reference to accompanying drawing.
The embodiment of the present application provides a kind of overpressure resistance detecting device, and the overpressure resistance detecting device can detect the pressure-resistant of body to be measured
Ability, the body to be measured can be battery, hereafter so that the overpressure resistance detecting device implements resistance test operation to battery as an example, to this Shen
Please embodiment provide overpressure resistance detecting device be introduced.
As depicted in figs. 1 and 2, the overpressure resistance detecting device that the embodiment of the present application is provided includes fixture 11, the and of inflation mechanism 12
Detection cell 13.The inside of fixture 11 has the receiving space for placing battery, and the fixture 11 can realize the spacing of battery, with
This prevents battery from the expansion of transition occurring under gas pressure.Inflation mechanism 12 can be connected with the inner space of battery, enter
And to the inside insufflation gas of battery, promoting battery to expand, the inflation mechanism 12 can be specifically air accumulator, the air accumulator
Air can be filled with to the inside of battery.Detection cell 13 is used to hold detection liquid, the enough folders with being placed with battery of the detection liquid energy
Tool 11 is in contact, and this detection liquid can be specifically water.
When detecting battery, battery is positioned in fixture 11 first, then filled by inflation mechanism 12 to the inside of battery
Enter gas so that the internal pressure of battery reaches setting value, then the fixture 11 for being placed with battery be positioned in detection cell 13 so that
Detection liquid in detection cell 13 is in contact with fixture 11.If battery, which is pressurized, there is breakage, then the gas for being filled with battery will
Spill, and entered by fixture 11 in detection liquid so that bubble occur in detection liquid, whereas if battery is under gas pressure
Do not occur bubble would not also occur in breakage, detection liquid.Therefore by detecting in liquid whether bubble occur it may determine that electricity
Whether pond there is breakage.It can be seen that, the overpressure resistance detecting device can carry out resistance test, and then the top of effective detection battery to battery
The intensity of the weld seam between weld seam, top cover and sealing nail between lid and aluminum hull, to improve the security of battery.Meanwhile, the inspection
Surveying device can judge whether battery damages exactly by detection cell, and testing result is more accurate.
When the inside insufflation gas of battery, battery will expand, and the effect of fixture 11 is exactly the expansion for limiting battery
Degree, but after battery takes out from detection cell 13, it is necessary to battery is taken out from fixture 11, in order to next battery
Detection.It will be in close contact after being expanded due to battery with fixture 11, and cause frictional force between the two larger, if only relied on
Artificial to take out battery, the taking-up of battery certainly will be caused, which to operate, wastes time and energy.Therefore, the resistance test dress that the embodiment of the present application is provided
Put and may also include extraction sector (not shown), the extraction sector can be connected with the inner space of battery, be extracted out with this
The gas of inside battery so that interval is formed between the inwall of battery and fixture 11, and then can be easily by battery from fixture
Taken out in 11.
To after the inside insufflation gas of battery, there is the risk disintegrated under gas pressure in battery, can be to detecting field
Operating personnel and other facilities in ground cause damage.In view of this, above-mentioned overpressure resistance detecting device may also include protective cover 14, should
