Description

Technical Field

[0001] The present invention relates to the technical field of battery detection, and in particular to a detection device for detecting battery separators. Background Art

[0002] In lithium-ion batteries, the separator plays a vital role. As a key component between the positive and negative electrodes of the battery, it must not only have good ionic conductivity to allow lithium ions to smoothly shuttle between the two electrodes during charging and discharging, but also have excellent electronic insulation to prevent direct contact between the positive and negative electrodes and cause short circuits, thereby ensuring the safe and stable operation of the battery and full performance.

[0003] Lithium-ion batteries are widely used in many fields such as electric vehicles, energy storage systems, and portable electronic devices. This has led to unprecedented attention to the quality and performance of battery separators. In order to ensure that battery separators can meet strict usage requirements, it is particularly important to accurately test their various performance indicators.

[0004] At present, there are various testing technologies for battery separators, including optical testing, electron microscope analysis, mechanical properties testing and other means. These testing methods can evaluate the various properties of separators to a certain extent, but in actual application, there is a common and thorny problem - separator wrinkles.

[0005] In the traditional inspection process, whether placing the diaphragm on the inspection platform or performing sampling, transfer and other operations, the diaphragm itself is very easy to wrinkle due to its thin texture, softness and certain elasticity. Once wrinkles appear, the refraction and scattering of light will be seriously affected during optical inspection, causing the originally clear image to become blurred. Some tiny holes and defects may be blocked by wrinkles, making it impossible for inspectors to accurately judge the actual quality of the diaphragm, resulting in inadequate inspection.

[0006] For electron microscope analysis, the presence of wrinkles will change the height difference on the surface of the diaphragm, affecting the focusing and imaging effects of electrons, and thus interfering with the precise observation of the diaphragm's microstructure. In mechanical property testing, wrinkles will also make the applied force not evenly distributed on the diaphragm, resulting in deviations in the test results and failure to truly reflect the mechanical properties of the diaphragm.

[0007] Therefore, the present invention provides a detection device for detecting battery separators to solve the above problems. Summary of the Invention
