Description

Technical Field

[0001] The utility model relates to a position identification device. Background Art

[0002] In order to allow more people to have easy access to reliable, sustainable and advanced energy, we are committed to developing and researching topics that contribute to energy efficiency. In existing vehicle technology, battery safety issues have always been the main research subject. If there is foreign matter in the battery, it is easy to cause faults such as short circuits and fires. However, if the outer layer of the battery is removed to expose the interior to the air in order to check for foreign matter, the solid electrolyte will decompose and the location of the foreign matter cannot be accurately known. Therefore, it is ideal to use X-rays to irradiate the interior of the battery without destroying the structure to detect whether there is foreign matter. In order to solve the above-mentioned problems, the utility model aims to locate the position of foreign matter, so as to further contribute to battery safety and energy efficiency.

[0034] Figure 1 It is a top view schematic diagram of a position identification device according to an embodiment of the utility model applied to a sample. Figure 2 yes Figure 1 Schematic diagram after X-ray irradiation. Figure 3 yes Figure 1 A schematic diagram of a cross-sectional side view of a position identification device applied to a sample. In this embodiment, the position identification device 100 is used, for example, in a vehicle battery (sample B described later), but can also be used in other devices that need to locate foreign objects inside an object, and the present invention is not limited thereto. Whenever possible, the same component symbols are used in the drawings and descriptions to represent the same or similar parts. Figures 1 to 3 The specific structure of the position recognition device 100 of this embodiment will be described.

[0035] Please refer to Figures 1 to 3 In this embodiment, the position recognition device 100 includes a metal sheet 110. The metal sheet 110 is, for example, in the shape of a long strip and is easily attached to the sample B, but can also be measured in a non-contact manner, and the present invention is not limited thereto. The metal sheet 110 includes an adhesive layer 112 and a first recognition portion 114. The adhesive layer 112 is disposed on one side of the metal sheet 110 (e.g., Figure 3 As shown, it is arranged on the side facing the sample B), and the other side of the metal sheet 110 faces the user (i.e. Figure 1 The surface seen from the perspective of Figure 3 The first identification portion 114 is disposed on at least one side of the metal sheet 110 (eg, Figure 1 As shown, the metal sheet 110 is close to one side of the sample B, and the first identification portion 114 is formed as a continuous pattern with a first spacing D1. Figure 1 As shown, the first identification portion 114 is a sawtooth structure, and is formed into a plurality of continuous sawtooth shapes with a first spacing D1 as a period, but in other embodiments not shown, it can also be other suitable shapes for positioning or measurement. Figure 2As shown in FIG. 1 , the jagged vertices and concave points in the first identification portion 114 can be used as indicators to indicate the position of the foreign matter F, and the relative position of the foreign matter F on the straight line in the sample B can be inferred by the first distance D1 known in advance.

[0036] It can be seen that in the position recognition device 100 of the present embodiment, the metal sheet 110 has an adhesive layer 112 and can be attached to the sample B, and the first recognition portion 114 has a continuous pattern with a fixed pitch, so after the sample B is irradiated with X-rays, the position of the foreign matter F can be located and measured by the first recognition portion 114. Furthermore, after the position of the foreign matter F is located, the cross-section of the sample B can be processed more accurately to analyze the situation of the sample B. Accordingly, the position recognition device 100 of the present embodiment can locate the position of the foreign matter F under the irradiation of X-rays.

[0037] Furthermore, in this embodiment, a second identification portion 116 is disposed on the other side of the metal sheet 110, and the second identification portion 116 is configured as a continuous pattern with a second interval D2. Figure 1 As shown, the second identification portion 116 is a sawtooth structure, and is formed into a plurality of continuous sawtooth shapes with a second spacing D2 as a period, but in other embodiments not shown, it can also be other suitable shapes for positioning or measurement. Figure 1 For example, the first distance D1 is set to be smaller than the second distance D2. In this way, the position recognition device 100 of this embodiment can more precisely locate the position of the foreign object F by combining different indicators (the first recognition unit 114 and the second recognition unit 116).

[0038] In addition, preferably, the position recognition device 100 has two metal sheets, namely, the metal sheet 110 and the metal sheet 120. One of the metal sheet 110 and the metal sheet 120 is formed of copper having X-ray absorption, and the other is formed of a metal other than copper and having X-ray absorption (such as aluminum), and is formed by die stamping, but the utility model is not limited thereto, and the metal sheet 110 and the metal sheet 120 may also be made of the same material, as long as the material is suitable for stamping processing and has good formability.

[0039] And, if Figure 1 As shown, the metal sheet 110 and the metal sheet 120 are perpendicular to each other and are formed in the same shape. The metal sheet 120 includes a third identification portion 122 and a fourth identification portion 124. The third identification portion 122 is formed as a continuous pattern with a third spacing D3, and the fourth identification portion 124 is formed as a continuous pattern with a fourth spacing D4. Figure 1As shown, the third identification portion 122 and the fourth identification portion 124 are sawtooth structures, and are respectively formed into a plurality of continuous sawtooth shapes with a third spacing D3 and a fourth spacing D4 as periods, and the third spacing D3 and the fourth spacing D4 are different from the first spacing D1 and the second spacing D2. However, in other embodiments not shown, the third spacing D3 and the fourth spacing D4 may also be the same as the first spacing D1 and the second spacing D2, and the utility model is not limited thereto. Thus, by arranging the metal sheet 110 and the metal sheet 120 perpendicular to each other, the coordinate position on the plane can be located, and the foreign body F can be more accurately located compared to a single metal sheet.

[0040] More preferably, the position identification device 100 may further include two mutually perpendicular metal sheets, that is, the metal sheet 110 and the metal sheet 120 are taken as a group, and then formed into a quadrilateral structure with another group of metal sheets 110 and metal sheets 120 (such as Figure 1 As shown in FIG. 1 , four metal sheets 110 and 120 are formed to surround the sample B. Thus, the foreign matter F can be more precisely located and measured compared to a set of metal sheets 110 and 120 .

[0041] In addition, in this embodiment, the metal sheets 110 and 120 each have a thickness T as a fifth interval as a measurement unit. Figure 3 As shown, the metal sheet 110 is attached to the sample B. After irradiating the sample B with X-rays in the side view direction, the thickness T of the metal sheet 110 can be used to infer the position of the foreign matter F in the thickness direction of the sample B. Combined with the measurement of the two metal sheets 110 and 120 mentioned above, the three-dimensional coordinate position of the foreign matter F in the sample B can be accurately located.

[0042] Furthermore, the thickness of the metal sheet 110 and the metal sheet 120 can be even smaller, for example, they can be attached to the sample B in the form of copper foil or aluminum foil, and the thickness T of the metal sheet 110 and the metal sheet 120 can also be set to be different, but the utility model is not limited to this. Preferably, the metal sheet 110 and the metal sheet 120 can be attached to the sample B at the micron (μm) level to measure tiny materials. In addition, the metal sheet 110 and the metal sheet 120 are ideally attached to the sample B in an environment not affected by the outside air to avoid the problem of decomposition of the solid electrolyte in the battery.

[0043] In summary, in the position identification device of the present invention, the metal sheet has an adhesive layer and can be attached to the object to be measured, and the first identification part has a continuous pattern with a fixed spacing, so the position of the foreign matter can be located and measured by the first identification part after the object to be measured is irradiated with X-rays. Furthermore, after the position of the foreign matter is located, the cross-section of the object to be measured can be more accurately processed to analyze the condition of the object to be measured. In addition, a second identification part is provided on the other side relative to one side of the metal sheet. In this way, the position identification device of the present invention can more finely locate the position of the foreign matter by combining different indicators. Accordingly, the position identification device of the present invention can locate the position of the foreign matter under the irradiation of X-rays.
