Detailed description of the invention
Fig. 1: the structural schematic diagram of the measurement soft-package battery volume devices of the utility model.
In figure: the unidirectional enabling battery closed box of 1-, 2- vacuum meter, 3- vacuum pump, 4- gas bottle, 5-U shape pipe linker, 6-
The thicker side of U-tube linker, the thinner side of 7-U type pipe linker, 8- gas-guide tube.
Specific embodiment
The utility model is described in further detail combined with specific embodiments below.
A kind of measuring device of novel soft package battery volume includes, unidirectional enabling battery closed box, vacuum meter, vacuum pump,
Gas bottle, rubber stopper, U-tube linker and several gas-guide tubes.
Unidirectional enabling closed box is cuboid or square.It is required that favorable sealing property, air tight, tall and erect acrylic material
Matter ZDPO1C type can be met the requirements.Respectively there is a circular opening on closed box top side and right side, and top side circular opening is used for and true
Empty table is connected, and right side aperture is connected by gas-guide tube with vacuum pump.
Vacuum meter is for monitoring the intracorporal air pressure of fully sheathed case.It is required that vacuum meter range is big, precision is high.MEACON-MIK-
Y190 type digital display vacuum meter (0.4 class precision, -100Kpa~200Kpa) can meet requirement.
Vacuum pump is transferred in gas cylinder for taking the intracorporal gas of fully sheathed case away, and require in pumping process gas without
