[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] like Figure 1As shown, this utility model provides a sampling, transfer, and storage device for preventing wrinkles in foil samples. It includes a lower base plate 10 and an upper cover plate 20 rotatably connected at one end. Both the lower base plate 10 and the upper cover plate 20 are configured as planar plate structures. A limiting member for restricting the sample is provided on one side of the upper cover plate 20 at the rotating end. A plurality of central sponges 60 are evenly provided in the middle part of the upper cover plate 20. A head sponge 70 is provided on the side of the upper cover plate 20 away from the rotating end. A hinge 30 is provided at the rotating end of the lower base plate 10 and the upper cover plate 20.

[0024] Specifically, the lower base plate 10 and the upper cover plate 20 are connected by a pair of hinges 30 to achieve the opening and closing effect. Both the lower base plate 10 and the upper cover plate 20 have a through-cut slit 11 at the same position when the head is closed for cutting the sample during sampling. The bottom of the lower base plate 10 is connected to four silicone buckles 41, which are used to connect the buckle seats 42 when the upper cover plate 20 is closed, and play a fixing role. The lower base plate 10 is provided with a tail clip 80 for fixing the head of the sample during sampling. The bottom surface of the tail clip 80 has a layer of silicone pad 81 for anti-slip function when fixing the sample. The upper cover plate 20 is provided with a tail sponge 50, a middle sponge 60 and a head sponge 70 on the bottom surface. The function is to fix the sample when the upper cover plate 20 is closed, to ensure that the sample is flat and to prevent wrinkles.

[0025] like Figure 1 As shown, the lower base plate 10 and the upper cover plate 20 are provided with a cutting slit 11 away from the rotating end. The cutting slit 11 is set parallel to the edge of the upper cover plate 20, which facilitates the cutting operation when the sample is clamped between the upper cover plate 20 and the lower base plate 10. After cutting, the sample is laid flat between the lower base plate 10 and the upper cover plate 20.

[0026] like Figure 1 As shown, two head sponges 70 are arranged in parallel. The two head sponges 70 are symmetrically arranged on both sides of the cut slit 11. When the cutter is located at the cut slit 11, the sample is pressed on both sides of the cut slit 11, which facilitates the cutter's cutting operation and prevents wrinkles from forming at the cutting position, thus maintaining the neatness of the cut.

[0027] like Figure 2 As shown, a tail clip 80 is provided on the lower base plate 10 near the rotating end, and a slot is provided on the upper cover plate 20 at the position corresponding to the tail clip 80.

[0028] A silicone pad 81 is fixed on the side of the tail clip 80 facing the bottom plate 10. The tail clip 80 is set as a right-angled triangular prism structure, and the bevel of the tail clip 80 faces the side of the knife seam 11.

[0029] The tail clip 80 is used to clamp and limit the sample. A silicone pad 81 is fixed at the bottom of the tail clip 80 to help limit the position of the sample and prevent the sample from shifting.

[0030] like Figure 1 As shown, the limiting component includes two tail sponges 50, which are symmetrically arranged on both sides of the slot, so that the samples on both sides of the tail clamp 80 are auxiliaryly limited, and the samples on both sides of the tail clamp 80 will not wrinkle, resulting in better performance.

[0031] Multiple buckles 41 are evenly fixed at the bottom of the lower base plate 10, and a buckle seat 42 for engaging the buckles 41 is provided at the top of the upper cover plate 20. The cooperation between the buckles 41 and the buckle seat 42 facilitates user operation and quickly defines the position between the lower base plate 10 and the upper cover plate 20.

[0032] The corners of the bottom plate 10 and the top cover plate 20 are both designed with rounded chamfers to prevent sharp points from touching and damaging the object.

[0033] The bottom of the lower base plate 10 and the top of the upper cover plate 20 are both fixed with reinforcing ribs, which prevents the lower base plate 10 and the upper cover plate 20 from deforming and ensures the flatness of the lower base plate 10 and the upper cover plate 20.

[0034] During sample collection, the sample head is fixed by the tail clip 80, and the sample is laid flat on the lower base plate 10. Then, the upper cover plate 20 is closed to make the sample lay flat and fit tightly against the plane of the lower base plate 10. Next, four buckles 41 are fastened to the buckle seat 42 to ensure that the lower base plate 10 and the upper cover plate 20 are tightly closed. Finally, the knife cuts the sample through the cut slit 11 to separate it from the large roll of sample, and then the transfer and storage operation can be carried out. This ensures that the sample is not wrinkled when it is taken from the large roll of sample, and during the sample transfer and storage process, ensuring that the data during sample testing is accurate and reliable. The operation is also convenient. This device can be used for sampling of separators and positive and negative electrode sheets of lithium batteries, and its application range is wider.

[0035] A tail sponge 50, a middle sponge 60, and a head sponge 70 are provided at the bottom of the upper cover plate 20 to elastically press the sample, making it suitable for samples of different thicknesses and further improving its applicability. In addition, elastic pressing of the sample can protect the sample from damage while making the position of the sample more stable.

[0036] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
