It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and those skilled in the art can obtain other embodiments without inventive effort based on the embodiments of the present invention, and all embodiments are within the protection scope of the present invention. The technical characteristics of the invention can be combined interactively on the premise of not conflicting with each other.

Referring to fig. 1 and 6, in an embodiment of the present invention, a battery leakage detecting apparatus includes a chassis 100, a cover 200, a vacuum pump 300, a display, and a controller. The cover body 200 is hollow to form a cavity 210, the bottom of the cavity 210 is of an open structure, the cover body 200 is arranged above the chassis 100, the cover body 200 can cover the chassis 100 to form a battery placing cavity, a battery to be tested is placed on the chassis 100, the cover body 200 covers the chassis 100, and the battery to be tested is located in the cavity 210. The inner side wall of the cavity 210 is provided with a first volatile component detection assembly 211 and a fan 212, the cover 200 is provided with a first pipeline 220 and a second pipeline 230, the first pipeline 220 and the second pipeline 230 are both communicated with the cavity 210, and the second pipeline 230 is provided with a valve 231.

It is understood that valve 231 may be a manual valve or an electrically controlled valve. In some embodiments, the valve 231 is an electric control valve, and the electric control valve is electrically connected to the controller, so that the controller can control the opening and closing of the valve 231, and the operation is more convenient.

The vacuum pump 300 is connected to the first pipeline 220 and is communicated with the cavity 210, and the vacuum pump 300 can pump out the gas in the cavity 210, so that the battery to be tested in the cavity 210 is in a vacuum environment. In a vacuum environment, if the sealing performance of the package of the battery to be tested is poor, the volatile components such as alkanes (e.g., ethylene, methane, ethane, etc.) and hydrogen fluoride in the battery can rapidly escape from the interior of the battery into the cavity 210 due to the pressure difference, so that the first volatile component detection assembly 211 arranged on the inner side wall surface of the cavity 210 can detect the volatile components. The vacuum pump 300 is adopted to enable the battery to be in a vacuum environment, the time for the volatile components in the leakage battery to overflow can be reduced, the detection can be completed under the limitation of the production period and the delivery deadline, and the defective products are prevented from flowing into a client.

The display is arranged on the outer side wall surface of the cover body 200, and the controller is electrically connected with the first volatile component detection assembly 211 and the display respectively. The first volatizable component detection element 211 detects the presence of volatizable components within the cavity 210 that escape from the interior of the battery and communicates the detection to the controller, which in turn communicates the detection to the display for clear and intuitive display.

In some embodiments, the fan 212 is electrically connected to a controller, which can control the on and off of the fan 212 and can communicate the operating status of the fan 212 to a display for clear and intuitive display.

It will be appreciated that the fan 212 may also be provided with another switch to control its on or off.

In the present embodiment, the controller and the display are integrated into a control display panel 400 having a control function and a display function. The control display panel 400 has control keys and a display screen. The control display panel 400 is disposed on the outer wall surface of the casing 200 and is electrically connected to the valve 231, the first volatilizable component detecting element 211 and the fan 212, respectively. It is understood that the control display panel 400 can receive and display the detection signal of the first volatile component detection unit 211 and the operation state signal of the fan 212, and can control the start and stop of the fan 212. In addition, the valve 231 in this embodiment is an electric control valve, and the opening and closing of the valve 231 can be controlled by operating the control display panel 400.

Specifically, a battery to be tested is placed on the chassis 100, the cover body 200 is covered, the battery to be tested is located in the cavity 210 of the cover body 200, and the vacuum pump 300 is used for pumping out gas in the cavity 210, so that the battery to be tested is in a vacuum environment. A poorly packaged battery will have volatile components that escape due to the pressure differential. After the battery to be tested is left standing for twenty to thirty minutes, the valve 231 on the second pipeline 230 is controlled to be opened by the control display panel 400, the volatile component in the cavity 210 is diffused to the inner wall of the cavity 210, the first volatile component detection assembly 211 located on the inner wall surface of the cavity 210 is detected, and a signal is transmitted to the control display panel 400 to be displayed.

However, when testing a large number of batteries, since the batteries to be tested are stacked in the cavity 210, the volatile components overflowing from the poorly packaged batteries may not flow to the inner sidewall of the cavity 210, and thus the first volatile component detection element 211 cannot detect the volatile components. By turning on the fan 212, the volatile components in the gaps between the cells are diffused, so that the first volatile component detection assembly 211 can more easily detect the volatile components in the cavity 210, and detection errors caused by the fact that gas cannot circulate are avoided.

It is to be understood that one or more fans 212 may be provided. In this embodiment, a plurality of fans 212 are disposed in the cavity 210, and two fans 212 are disposed on four inner side wall surfaces of the cavity 210, so that when the fans 212 are turned on, the gas in the cavity 210 can be distributed more uniformly, and the detection is more accurate. It is understood that the specific number and arrangement of the fans 212 is not limited herein.

In some embodiments, a second volatizable component detection assembly 232 is disposed on an inner wall of second conduit 230, and the controller is electrically connected to second volatizable component detection assembly 232 and capable of transmitting information detected by second volatizable component detection assembly 232 to a display for visual display. In this embodiment, the second volatile component detecting element 232 is electrically connected to the control display panel 400, and the second volatile component detecting element 232 can detect the volatile component in the second pipeline 230, and transmit the detection signal to the control display panel 400 for display.

After the battery to be tested is standing still, the valve 231 on the second pipeline 230 is opened to allow the gas in the cavity 210 to flow normally, the gas in the cavity 210 and the gas outside the cover 200 may generate gas exchange, and the volatile component in the battery may flow out from the second pipeline 230 and be undetectable by the first volatile component detection assembly 211 in the cavity 210, so as to make an error judgment and allow the badly packaged battery to flow into the client. The second volatile component detection assembly 232 arranged in the second pipeline 230 can detect whether gas flowing through the second pipeline 230 exists gas overflowing from the interior of the battery, and accuracy of the battery leakage detection device is improved.

In some embodiments, the inner wall of the first pipeline 220 is provided with a third volatile component detecting assembly 221, the controller is electrically connected to the third volatile component detecting assembly 221, and the controller can transmit the signal detected by the third volatile component detecting assembly 221 to the display and clearly and intuitively display the signal.

In this embodiment, the third volatile component detecting element 221 is electrically connected to the control display panel 400, and the third volatile component detecting element 221 can detect the gas flowing through the first pipeline 220, so as to prevent the volatile component in the poorly packaged battery from being extracted during the vacuum pumping process of the vacuum pump 300, so that the first volatile component detecting element 211 in the cavity 210 cannot detect the volatile component. The third volatile component detection module 221 can detect whether the volatile component in the battery exists in the pumped gas, and transmits the detected signal to the control display panel 400 to be displayed, so that misjudgment caused by vacuum pumping is avoided, and the accuracy of the battery leakage detection device is improved.

In this embodiment, the first volatile component detecting element 211, the second volatile component detecting element 232, and the third volatile component detecting element 221 are all gas sensors capable of detecting gases (such as alkanes, hydrogen fluoride, etc.) volatilized from the battery electrolyte, and may be semiconductor type sensors, which are not limited specifically herein.

In some embodiments, there are a plurality of first volatizable component detection elements 211, and each of the plurality of first volatizable component detection elements 211 is disposed on an inner wall surface of cavity 210. It is understood that the chamber 210 has four inner side wall surfaces and one inner top wall surface, and that each of the four inner side wall surfaces and the one inner top wall surface may be provided with one first volatizable component detection assembly 211 or may be provided with a plurality of first volatizable component detection assemblies 211. It is understood that the upper, middle and lower portions of the four inner side wall surfaces may be provided with the first volatile component detecting element 211.

In the present embodiment, four inner side wall surfaces of the cavity 210 are each provided with four first volatizable component detection elements 211, and the four first volatizable component detection elements 211 of each inner side wall surface are arranged around the central circumference of the inner side wall surface at the same pitch.

By the arrangement, each position of the inner wall surface of the cavity 210 can be detected, and the detection accuracy is improved. It is understood that first volatizable component detection assemblies 211 may be disposed in other numbers and in other arrangements.

It is understood that the number of the second volatizable component detection assemblies 232 and the number of the third volatizable component detection assemblies 221 may be one or more, and is not particularly limited herein.

In this embodiment, the lower surface of the cover 200 is provided with an annular groove, and the sealing rubber strip 240 is correspondingly disposed in the groove.

The vacuum gauge 310 is provided to enable an operator to know the environmental condition inside the chamber 210 and control the vacuum pump 300, so as to improve the accuracy of the detection.

It is understood that the vacuum gauge 310 is a common gauge in the art, and the structure, principle and method of use thereof will be apparent to those skilled in the art and will not be described in detail herein.

In some embodiments, the vacuum pump 300 is provided with a vacuum level detection assembly capable of detecting the vacuum level in the chamber 210, and the vacuum gauge 310 functions as the vacuum gauge 310, so that the vacuum gauge 310 does not need to be additionally provided on the shield 200.
