The invention provides a liquid battery detection device, please refer to fig. 1, which comprises a gland 20, a detection table 10 and a detector, wherein the gland 20 is arranged on the detection table 10, and an accommodating space 40 for installing a piece to be detected is arranged between the gland 20 and the detection table 10; the detection table 10 is provided with a first through hole 13 communicated with the accommodating space 40, the gland 20 is provided with a second through hole 21 communicated with the accommodating space 40, and the detector is communicated with the first through hole 13 through a pipeline.
In this embodiment, the liquid battery detection apparatus is used to detect the sealing performance of the liquid metal battery package. In addition, the liquid battery detection device can also be used for detecting the air tightness of packages except the liquid battery. The detector can be matched with a helium mass spectrometer leak detector, and a helium mass spectrometer leak detection method is utilized to test the sealing performance of the liquid metal battery package.
Taking the to-be-tested piece as an example of liquid battery package, when testing the to-be-tested piece, firstly, the to-be-tested piece is prevented from being on the detection platform 10, that is, the to-be-tested piece is to be placed in the accommodating space 40, and when installing the to-be-tested piece in the accommodating space 40, it is required to ensure that the to-be-tested piece covers the first through hole 13. In this embodiment, the gland 20 and the detection table 10 adopt a detachable connection mode, so that convenience of installing a to-be-detected part in the accommodating space 40 is improved. Specifically, the cover body is taken down from the detection table 10, and then the to-be-detected piece is placed on the detection table 10, so that the to-be-detected piece covers the first through hole 13. After the to-be-detected piece is installed, the gland 20 is fixed on the detection table 10 in a screw fixing mode, the to-be-detected piece is compressed by adjusting the tightness degree of the screw, and the to-be-detected piece is prevented from moving. Wherein, screws and threaded holes can be arranged at the edge positions of the gland 20 and the detection table 10, thereby avoiding occupying the accommodating space 40.
After the to-be-tested piece is installed, the to-be-tested piece can be inflated into the second through hole 21, wherein the accommodating space 40 can be a closed space or an open space, and when the to-be-tested piece is arranged in the open space, the to-be-tested piece needs to be continuously inflated into the second through hole 21, so that the air pressure of the accommodating space 40 is larger than the external air pressure. Because the to-be-detected piece covers the first through hole 13 and the accommodating space 40 keeps high pressure, when the surface of the to-be-detected piece has a leak hole or a crack, gas enters the detection space from the first through hole 13 through the leak hole and the crack under the action of air pressure, and when the detector detects air flow, the leak hole or the crack is shown on the to-be-detected piece.

Meanwhile, the liquid battery detection device also comprises a vacuum generator which is communicated with the sealing cavity 12. A vacuum environment is formed in the sealed cavity 12 through the vacuum generator, so that the detection accuracy and reliability are further improved by using a vacuum helium mass spectrum leak detection method.
In addition, the positions of the first through hole 13 and the second through hole 21 can be adjusted, for example, the first through hole 13 and the second through hole 21 are correspondingly arranged, so that the to-be-detected part is located between the first through hole 13 and the second through hole 21 after the to-be-detected part is installed, gas injected from the second through hole 21 can be directly applied to the surface of the to-be-detected part, and the detection effect is ensured.
According to the technical scheme, the piece to be detected is arranged in the accommodating space 40, the piece to be detected covers the first through hole 13, air is injected into the second through hole 21, and the detector is used for detecting whether air flows out from one side of the first through hole 13 or not, so that whether a leak hole or a crack exists on the piece to be detected or not is detected. When the surface of the packaging component has a leak hole, gas can enter the detector from the first through hole 13 through the leak hole, so that the leakage quantity of the detected component is measured, and the detection accuracy is improved.
