Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery detection, in particular to a device for lithium battery leakage detection. Background Art

[0002] Lithium batteries are widely used in mobile phones, laptops, electric vehicles, and other fields due to their high energy density and long life. However, the flammable and explosive electrolytes contained in lithium batteries can cause serious safety accidents such as fire or explosion when leaking or short-circuiting, making lithium battery leak detection crucial.

[0003] During a lithium battery leak, the electrolyte evaporates, producing a gas called "vapor electrolyte" around the leak point. This gas provides clues for detecting a leak. However, traditional detection methods, such as gas detectors or visual inspection, have numerous shortcomings.

[0004] Traditional gas detectors or visual inspection methods typically take a long time to complete lithium battery leak detection. These methods often require technicians to possess certain expertise and operational experience to accurately determine whether a battery is leaking. This high standard limits the selection of inspectors, increases labor costs, and hinders the widespread adoption and promotion of this technology. Due to their reliance on manual operation and interpretation, the accuracy and consistency of traditional detection methods can be affected by human factors, leading to misjudgments or missed detections. Improving detection accuracy and reliability is crucial to ensuring the safe use of lithium batteries.

[0005] At the same time, traditional lithium battery leak detection technology can usually only detect batteries one by one, which is inefficient when processing large numbers of batteries.

[0006] In summary, existing lithium battery leak detection technology faces challenges such as slow detection speed, high technical requirements, inability to test multiple batteries in parallel, insufficient detection accuracy and reliability, and a need to improve safety and environmental adaptability. These issues have limited the development and application of lithium battery leak detection technology. Therefore, there is an urgent need for a new detection device and method to address these issues. Utility Model Content

And "inner" and "outer" are relative to the outline of the device.

[0024] As shown in Figure 1 , Figure 2 and Figure 3 , a device for lithium battery leak detection, the specific structure is as follows: the device includes a base plate 1 and a vertical plate 2, the base plate 1 and the vertical plate 2 are arranged in a horizontal and vertical intersection manner. The base plate 1 is provided with a battery clamp 3 near the vertical plate 2, and the clamp is connected with the vertical plate 2 through bolts, so that the battery can be stably fixed on the base plate 1. In order to meet the detection needs of lithium batteries of different shapes, the battery clamp 3 is designed to be replaced according to the shape of the detected battery, which provides great flexibility.

[0025] The vertical plate 2 is provided with a detection support 4, and the detection support 4 is provided with a detection device 5. The detection device 5 is composed of a detection head 51, a detection clamp 52 and a motor 53. The motor 53 is installed on the detection support 4, the detection clamp 52 is located below the motor 53, and the detection head 51 is arranged below the detection clamp 52. The detection head 51 adopts an electrolyte sensor, which can accurately sense the existence of electrolyte gas.

[0026] In order to realize the up and down movement of the detection head 51, the motor 53 is connected and driven with the detection clamp 52 through the screw rod. This design enables the detection head 51 to be accurately moved to the top of the lithium battery to be detected for detection under the driving of the motor 53 through the detection clamp 52.

[0027] A plurality of detection devices 5 are arranged on the detection support 4, preferably four at the same time. Such a design enables the device to simultaneously detect a plurality of lithium batteries, greatly improving the detection efficiency.

[0028] In order to further improve the safety and portability, the entire detection device is also equipped with a detection cabinet 6, and the vertical plate 2 is arranged on the detection cabinet 6.

In addition, the bottom of the detection cabinet 6 is provided with universal wheels, so that the entire device can be easily moved to different detection sites.

[0029] Specific use method:

[0030] When using the lithium battery leak detection device of the utility model, first of all, according to the shape of the lithium battery to be detected, select the appropriate battery clamp 3, and fix it on the vertical plate 2 through the bolt. Then, place the lithium battery to be detected in the battery clamp 3, and ensure its stability.

[0031] Subsequently, start the detection device 5, and the motor 53 will drive the detection clamp 52 and the detection head 51 to move to the top of the lithium battery. The detection head 51, i.e. the electrolyte sensor, starts to work and senses whether there is electrolyte gas around the lithium battery. If there is a leak, the sensor will immediately detect and send a signal.

[0032] Since a plurality of detection devices 5 are arranged on the detection support 4, a plurality of lithium batteries can be detected at the same time, greatly improving the detection efficiency. After detection is completed, the detection head 51 will return to the initial position under the driving of the motor 53, waiting for the next detection. The whole process is highly automated, which not only reduces the skill requirement of the detection personnel, but also improves the detection accuracy and consistency.
