[0023] In order to make the technical problems to be solved by the application, the technical solutions and the beneficial effects more clearly, the following will further describe the application in detail by combining the drawings and the embodiments. It should be understood that the specific embodiments described herein are only used to explain the application, and are not used to limit the application.

[0024] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0025] In addition, the terms "first", "second" are only used for description purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features. In the description of the application, the meaning of "multiple" is two or more than two, unless otherwise specifically limited.

[0026] In order to illustrate the technical solutions described in the application, the following will be described by specific embodiments.

[0027] Referring to Figs. 1 to 3 As shown in the drawings, the battery top cover helium detection system provided by the embodiments of the present application can avoid the problems of missed detection and repeated detection.

[0028] The battery top cover helium detection system comprises a helium detection clamp 10 and a helium mass spectrometer 20. The helium detection clamp 10 is provided with at least one detection station for placing a battery top cover 30. As an example, the helium detection clamp 10 is provided with two detection stations, and one detection station is used to place one battery top cover 30. The helium mass spectrometer 20 is used to perform helium detection on the battery top cover 30 in the detection station.

[0029] It should be noted that the structure of the helium mass spectrometer 20 and the helium detection clamp 10 is not specifically limited in the embodiments of the present application, and the skilled person can make corresponding design according to actual needs.

[0030] The battery top cover helium detection system provided by the embodiments of the present application further comprises a sensor 40 and a control switch. The sensor 40 is electrically connected to the control system of the helium mass spectrometer 20, and the sensor 40 is used to sense whether the battery top cover 30 is in the detection station. As an example, the sensor 40 is a laser sensor. In the embodiments of the present application, the sensor 40 clears the recorded number of helium detections when it senses that the battery top cover 30 has left the detection station.

[0031] The control switch is electrically connected to the control system. The control switch is used to trigger the control system to start the helium mass spectrometer 20 when the control switch is triggered and the number of helium detections is zero or has been cleared, and is used to not trigger the control system to start the helium mass spectrometer 20 when the number of helium detections has not been cleared. In other words, in the case where the number of helium detections has not been cleared, repeated detection of the same battery top cover 30 can be avoided, and thus missed detection can also be avoided (i.e., triggering the control switch can avoid missed detection in the case where it is not determined whether detection has been performed).

[0032] As an example, when the helium mass spectrometer 20 is started, the helium mass spectrometer 20 starts to perform helium detection on the battery top cover 30 in the detection station.

[0033] As an example, the control switch can be a hardware button switch or a software touch screen switch, and the embodiments of the present application do not specifically limit this.

[0034] The working principle of the above-mentioned battery top cover helium detection system is as follows:

[0035] In the initial state (which can be considered as the number of helium detection is zero or has been cleared), when the battery top cover 30 is placed in the detection station and the control switch is triggered, the control system can be successfully triggered to start the helium mass spectrometer 20, at this time, the helium detection is carried out, and the number of helium detection is 1. As an example, the number of helium detection can be counted by a counter. For example, the counter is connected to the control system or the helium mass spectrometer 20, so as to count when the helium mass spectrometer 20 is started. In this case, when the control switch is triggered again, the control system cannot be triggered to start the helium mass spectrometer 20 because the number of helium detection is not zero, thereby avoiding the problems of missed detection and repeated detection. Until the inductor 40 senses that the battery top cover 30 leaves the detection station, the recorded number of helium detection is cleared, and when the control switch is triggered again, the control system can be triggered to start the helium mass spectrometer 20 because the number of helium detection has been cleared. As an example, the inductor 40 is connected to the counter to clear the number of helium detection.

[0036] In some embodiments, the battery top cover helium detection system further comprises a code scanner 50 and a memory, the code scanner 50 is used for scanning the battery top cover 30 on the detection station and storing the scanning information in the memory. The memory is also connected to the helium mass spectrometer 20, and is used for storing the helium detection result corresponding to the scanning information.

[0037] As an example, the battery top cover 30 is provided with a two-dimensional code 31, and the two-dimensional code 31 stores the production information of the battery top cover 30. For example, each battery top cover 30 has a unique two-dimensional code 31. For example, the production information includes the unique number of the battery top cover 30.

[0038] The working principle of the above-mentioned battery top cover helium detection system is as follows:

[0039] In the initial state (which can be considered as the number of helium detection is zero or has been cleared), when the battery top cover 30 is placed in the detection station, the code scanner 50 scans the battery top cover 30 on the detection station and stores the scanning information in the memory. Then, when the control switch is triggered, the control system can be successfully triggered to start the helium mass spectrometer 20 to carry out helium detection, and the helium detection result corresponding to the scanning information is stored at the same time, at this time, the number of helium detection is 1. In this case, when the control switch is triggered again, the control system cannot be triggered to start the helium mass spectrometer 20 because the number of helium detection is not zero, thereby avoiding the problems of missed detection and repeated detection. Until the inductor 40 senses that the battery top cover 30 leaves the detection station, the recorded number of helium detection is cleared, and when the control switch is triggered again, the control system can be triggered to start the helium mass spectrometer 20 because the number of helium detection has been cleared.

[0040] In summary, the battery top cover helium detection system provided by the embodiments of the present application can avoid the problems of missed detection, repeated detection and missed scanning by setting the inductor 40 and the code scanner 50.

[0041] The above-described embodiments are only used to illustrate the technical solutions of the present application, but not limit the present application; although the present application is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
