[0002] With the development of modern industry, lithium battery cells have been commercially applied to various industries, thus giving rise to aluminum-plastic films. The quality inspection of aluminum-plastic films under high temperature and high humidity conditions is very important. One of the inspections is the water blocking performance test, specifically to detect its permeability under high temperature and high humidity conditions, so as to know the sealing performance.
[0003] In order to test the water blocking performance of the aluminum-plastic film, it is necessary to prepare samples of the aluminum-plastic film first. Specifically: overlap two pieces of aluminum-plastic film, heat-seal three sides and leave one side open to form a Figure 1 detection sample as shown, and it is necessary to ensure that the shapes of all detection samples are the same and the widths of the heat-sealed edges in each single detection sample are the same; in the related art, it is difficult to keep the heat-sealed dimensions of the detection samples consistent, and at the same time, during heat-sealing, the places that do not need to be heat-sealed are easily adhered due to heat conduction, resulting in uneven heat-sealed edges, thus affecting the test results of the water blocking performance of the aluminum-plastic film.
[0004] Therefore, how to solve the problem that the heat-sealed dimensions of the existing detection samples are difficult to keep consistent is a technical problem that those skilled in the art need to solve urgently.
[0005] It should be noted that the above information disclosed in this background technical part is only used to understand the background technology of the concept of this application. Therefore, it is not considered that the above description constitutes information of the prior art. Content of the Utility Model

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, in the drawings, the thickness of components may be exaggerated or reduced for effective description of the technical content.
[0040] The following will describe in detail some embodiments of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.
[0041] As Figure 2 shown, at least one embodiment provides a tooling for water-blocking test sample preparation of an aluminum-plastic film, which includes: a bottom plate 1, on which an upper positioning plate 2, a middle positioning plate 3, and a lower positioning plate 4 are stacked; wherein the upper positioning plate 2, the middle positioning plate 3, and the lower positioning plate 4 each include a positioning angle at the positioning end 51; the upper reference surface 21 of the upper positioning plate 2 and the lower reference surface 41 of the lower positioning plate 4 are vertically coplanar to form a positioning area; and the middle reference surface 31 of the middle positioning plate 3 protrudes from the upper reference surface 21 to divide the positioning area into an upper card slot 52 and a lower card slot 53 for aluminum-plastic film 81 positioning.
[0042] Specifically, two identical aluminum-plastic films 81 are respectively placed in the upper card slot 52 and the lower card slot 53, and the right angles of the corresponding aluminum-plastic films 81 are fitted with the right angles of the upper positioning plate 2 or the lower positioning plate 4. At this time, the two aluminum-plastic films 81 completely overlap, thereby ensuring that the contour dimensions of the detected samples heat-sealed are all the same.
[0043] As Figure 3 、 Figure 4 shown, in some embodiments, a middle baffle 32 is provided on the middle reference surface 31 of the middle positioning plate 3; wherein the lower surface of the middle baffle 32 is coplanar with the lower surface of the middle positioning plate 3; and the upper surface of the middle baffle 32 is lower than the upper surface of the middle positioning plate 3 to form a middle card slot 54 for Teflon high-temperature cloth 83 positioning.
[0044] Specifically, due to the existence of the middle baffle 32, a Teflon high-temperature cloth 82 can be placed on the middle baffle 32. The Teflon high-temperature cloth 82 can provide heat insulation to prevent adhesion at the places of the aluminum-plastic film 81 that do not need heat sealing caused by heat conduction. At the same time, since the upper surface of the middle baffle 32 is lower than the upper surface of the middle positioning plate 3, after the Teflon high-temperature cloth 82 is placed, its height will not protrude from the upper surface of the middle positioning plate 3. Among them, the Teflon high-temperature cloth 82 is located between two aluminum-plastic films 81 and has a right angle. When placing, the right angle of the Teflon high-temperature cloth 82 is fitted with the right angle of the middle baffle 32, thus realizing the positioning of the Teflon high-temperature cloth 82.
[0045] Such as Figure 5 shown, in some embodiments, the middle reference plane 31 includes: a first middle reference edge 311 and a second middle reference edge 312; the first middle reference edge 311 and the second middle reference edge 312 are orthogonally arranged to form a corresponding positioning angle.
[0046] In some embodiments, the upper reference plane 21 includes: a first upper reference edge 211 and a second upper reference edge 212; the first upper reference edge 211 and the second upper reference edge 212 are orthogonally arranged to form a corresponding positioning angle.
[0047] Optionally, the positioning angle is set to a right angle of 90 degrees according to the practical scenario.
[0048] Such as Figure 4 、 Figure 5 shown, in some embodiments, the width A between the first middle reference edge 311 and the first upper reference edge 211 of the upper positioning plate 2; the width B between the second middle reference edge 312 and the second upper reference edge 212 of the upper positioning plate 2; among them, the width A is equal to the width B.
[0049] Specifically, after two aluminum-plastic films 81 and a Teflon high-temperature cloth 82 are fitted with the corresponding right angles, since the width A is equal to the width B, the widths of the two heat-sealing edges 83 are ensured. At the same time, when cutting the aluminum-plastic film 81 and the Teflon high-temperature cloth 82, the width of the Teflon high-temperature cloth 82 is set to be equal to the width of the aluminum-plastic film 81 minus twice the width of the heat-sealing edge 83. Therefore, when one heat-sealing edge 83 in the length direction is defined, the relative heat-sealing edge 83 in the other length direction is also defined. At this time, only the stacked three-layer film needs to be clamped by the corresponding fixing parts to ensure that the three-layer film does not displace during heat sealing, so that the widths of the three heat-sealing edges 83 in one test sample are consistent, and at the same time, the test samples can also be kept consistent with each other.
[0050] Refer to Figure 6, after the three-layer film is stacked, the first fixing clip 91 clamps the end of the three-layer film on the right-angled side of the positioning plate; wherein, the first fixing clip 91 is closely attached to the side wall of the positioning plate.
[0051] Reference Figure 7 , after the first fixing clip 91 clamps, turn up the Teflon high-temperature cloth 82 protruding from the aluminum-plastic film 81, and then clamp this end with the second fixing clip 92. Subsequently, the two sides in the length direction of the three-layer film can be heat-sealed; wherein, both the first fixing clip 91 and the second fixing clip 92 are closely attached to the side wall of the positioning plate.
[0052] Reference Figure 8 , after the two sides in the length direction of the three-layer film are heat-sealed, remove the first fixing clip 91. Subsequently, place the three-layer film horizontally, make the end where the first fixing clip 91 is removed fit with the right angle of the upper positioning plate 2. After fitting, clamp the side of the three-layer film with the third fixing clip 93 for fixation. Subsequently, heat-seal the side where the first fixing clip 91 is removed. Finally, form a sample as shown in Figure 8 , at this time, just draw out the Teflon high-temperature cloth 82 to form a test sample as shown in Figure 1 shown.
[0053] In one application scenario, the upper positioning plate 2, the middle positioning plate 3, and the lower positioning plate 4 are all approximately "C"-shaped.
[0054] In another application scenario, as shown in Figure 10 , the upper positioning plate 2, the middle positioning plate 3, and the lower positioning plate 4 are all "L"-shaped.
[0055] Specifically, both the "C" shape and the "L" shape can form a 90-degree right angle at the positioning end 51.
[0056] In summary, the tooling for preparing samples for the water-blocking test of the aluminum-plastic film positions the two layers of aluminum-plastic film 81 and one layer of Teflon high-temperature cloth 82 respectively through the upper positioning plate 2, the middle positioning plate 3, and the lower positioning plate 4 with right angles. After positioning, they can be fixed by corresponding fixing clips to prevent the three-layer film from shifting during the heat-sealing process; meanwhile, the presence of the Teflon high-temperature cloth 82 can prevent the two layers of aluminum-plastic film 81 from sticking in other places that do not need to be heat-sealed during the heat-sealing process.
[0057] In this article, when it is mentioned that the first component is located on the second component, this can mean that the first component can be directly formed on the second component, or a third component can be inserted between the first component and the second component.
[0058] As used herein, when an element or layer is referred to as being "on," "engaged to," "connected to," "attached to," or "coupled to" another element or layer, it can be directly on, engaged, connected, attached, or coupled to the other element or layer, or intervening elements or layers may be present.

Other words used to describe the relationship between elements should be interpreted in a similar manner (e.g., "between" versus "directly between," "adjacent" versus "directly adjacent," etc.). As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0059] In this document, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." modify the entire list of elements when following a list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.
[0060] The terms used herein are for the purpose of describing particular example configurations only and are not intended to be limiting. As used herein, the singular articles "a," "an," and "the" may also be intended to include the plural forms, unless the context clearly indicates otherwise. The terms "comprises," "comprising," and "having" are inclusive and thus specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein should not be construed as necessarily requiring them to be performed in the particular order discussed or illustrated, unless specifically identified as an order of performance.

[0061] As used herein, phrases such as "in one embodiment," "according to one embodiment," "in some embodiments," etc. generally refer to the fact that a particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of the present disclosure. Thus, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," etc. are used "as an example, instance, or illustration." Any embodiment, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or superior to other embodiments, aspects, or designs. Instead, the use of the terms "example," "exemplary," etc. is intended to present concepts in a concrete manner.
[0062] In the description of the embodiments of the present utility model, unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer or section discussed above may be referred to as the second element, component, region, layer or section.
[0064] Spatially relative terms, such as "inner", "outer", "below", "beneath", "lower", "above", "upper", etc., may be used herein to facilitate describing the relationship of one element or feature to another element or feature as illustrated in the figures. In addition to the orientation depicted in the figures, spatially relative terms are intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is turned over, an element described as "below" or "beneath" another element or feature will then be oriented "above" the other element or feature. Thus, the exemplary term "below" can encompass both an above and below orientation. The device may be otherwise oriented (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0065] In the above discussion, unless otherwise stated, when used to describe a numerical value, the terms "about", "approximately", "substantially", etc. mean a variation of + / −10% of that value.
[0066] Based on the inspiration of the ideal embodiments of the present utility model as described above, through the above description, relevant workers can completely make various changes and modifications within the scope not deviating from the technical idea of this utility model.
