Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a pressing structure and a die-cutting device for improving the folding of a tab. Background Art

[0002] The empty foil area in the pole piece used to form the pole lug is thin and has low strength, and is prone to deformation or wrinkles during the conveying and folding process. Therefore, in the process of forming the pole lug of the pole piece, the empty foil area can be ribbed by a rib wheel to increase the strength of the pole lug and ensure the effect of the pole lug cutting.

[0003] The existing corrugation wheel is used to corrugate the empty foil area, which can enhance the strength of the tab and obtain a better tab cutting effect. However, in the actual production operation, the tab deformation and wrinkles still occur, which affects the tab cutting effect and the quality and yield rate of the battery. Utility Model Content

[0004] In view of this, the purpose of the embodiments of the present application is to provide a pressing structure and a die-cutting device for improving the folding of the pole tab, so as to solve the technical problem of how to further improve the strength of the pole tab and reduce the probability of the occurrence of deformation, wrinkles and the like of the pole tab.

[0005] In a first aspect, an embodiment of the present application provides a pressed structure, which includes: a first pressing wheel and a second pressing wheel; the outer surface of the first pressing wheel is provided with a first reinforcing rib pattern, and the outer surface of the second pressing wheel is provided with a second reinforcing rib pattern;

[0006] The first pressing wheel is disposed on one side of the pole ear to be pressed, and the first pressing wheel is configured to press one side of the pole ear during the passage of the pole ear;

[0007] The second pressing wheel is disposed on the other side of the pole lug, and the second pressing wheel is configured to press the other side of the pole lug during the passage of the pole lug.

[0008] In the above-mentioned implementation process, the pressing structure includes a first pressing wheel and a second pressing wheel; and the outer surface of the first pressing wheel is provided with a first reinforcing rib pattern, and the outer surface of the second pressing wheel is provided with a second reinforcing rib pattern. Since the first pressing wheel and the second pressing wheel are respectively arranged on both sides of the pole ear to be pressed, one side of the pole ear can be pressed based on the first pressing wheel during the passage of the pole ear, and the other side of the pole ear can be pressed based on the second pressing wheel, and the first reinforcing rib pattern and the second reinforcing rib pattern can be pressed on both sides of the pole ear respectively. Compared with the existing unilateral pressing rib treatment method, the pressing structure provided by the present application can further improve the strength of the pole ear, thereby reducing the probability of deformation, wrinkles and other phenomena of the pole ear. The technical problem of how to further improve the strength of the pole ear and reduce the probability of deformation, wrinkles and other phenomena of the pole ear is solved.

[0009] Optionally, in an embodiment of the present application, the pattern types of the first reinforcing rib pattern and the second reinforcing rib pattern are inconsistent.

[0010] In the above implementation process, since the texture types of the first reinforcement rib pattern and the second reinforcement rib pattern are inconsistent, the complexity of the reinforcement rib pattern on both sides of the pressed pole ear can be further increased to further improve the strength of the pressed pole ear and better reduce the probability of deformation, wrinkling and other phenomena of the pole ear.

[0011] Optionally, in an embodiment of the present application, the first reinforcement rib pattern includes a dot pattern, and the second reinforcement rib pattern includes a line pattern; wherein the first pressing wheel is configured to press one side of the pole lug based on the dot pattern during the process of the pole lug passing through the first roller; and the second pressing wheel is configured to press the other side of the pole lug based on the line pattern during the process of the pole lug passing through the second roller.

[0012] In the above implementation process, the dot pattern can be pressed to one side of the pole ear when the pole ear passes through the first roller, and the line pattern can be pressed to the other side of the pole ear when the pole ear passes through the second roller; thereby increasing the pattern complexity on both sides of the pressed pole ear, further improving the strength of the pressed pole ear, and better reducing the probability of deformation, wrinkles and other phenomena of the pole ear. Since the dot pattern and the line pattern are pressed in the process of the pole ear passing through different rollers respectively; when the dot pattern is pressed on one side of the pole ear, the pressing force of the line pattern can be controlled; or when the line pattern is pressed on the other side of the pole ear, the pressing force of the dot pattern can be controlled to reduce the probability of curling of the pole ear after pressing. In addition, the design and production difficulty of the dot pattern and the line pattern are relatively low; using the dot pattern as the first reinforcing rib pattern and the line pattern as the second reinforcing rib pattern can reduce the manufacturing difficulty of the pressed structural parts while improving the strength of the pressed pole ear.

[0013] Optionally, in an embodiment of the present application, the first reinforcement rib pattern includes a dot pattern, and the second reinforcement rib pattern includes a polygonal pattern; wherein the first pressing wheel is configured to press one side of the pole lug based on the dot pattern during the passage of the pole lug; and the second pressing wheel is configured to press the other side of the pole lug based on the polygonal pattern during the passage of the pole lug.

[0014] In the above implementation process, the dot pattern can be pressed to one side of the tab when the tab passes through the first roller, and the polygonal pattern can be pressed to the other side of the tab when the tab passes through the second roller; thereby increasing the pattern complexity on both sides of the tab after pressing, further improving the strength of the tab after pressing, and better reducing the probability of deformation, wrinkles and other phenomena of the tab. Since the dot pattern and the polygonal pattern are pressed in the process of the tab passing through different rollers respectively; when the dot pattern is pressed on one side of the tab, the pressing force of the polygonal pattern can be controlled; or when the polygonal pattern is pressed on the other side of the tab, the pressing force of the dot pattern can be controlled to reduce the probability of curling of the tab after pressing. In addition, since the pattern complexity of the polygonal pattern is higher, the strength of the tab after pressing can be further improved.

[0015] Optionally, in an embodiment of the present application, the first reinforcement rib pattern includes a linear pattern, and the second reinforcement rib pattern includes a polygonal pattern; wherein the first pressing wheel is configured to press one side of the pole lug based on the linear pattern during the process of the pole lug passing through the first roller; and the second pressing wheel is configured to press the other side of the pole lug based on the polygonal pattern during the process of the pole lug passing through the second roller.

[0016] In the above implementation process, the linear pattern can be pressed to one side of the lug when the lug passes through the first roller, and the polygonal pattern can be pressed to the other side of the lug when the lug passes through the second roller; thereby increasing the pattern complexity on both sides of the lug after pressing, further improving the strength of the lug after pressing, and better reducing the probability of deformation, wrinkles and other phenomena of the lug. Since the linear pattern and the polygonal pattern are pressed in the process of the lug passing through different rollers respectively; when the linear pattern is pressed on one side of the lug, the pressing force of the polygonal pattern can be controlled; or when the polygonal pattern is pressed on the other side of the lug, the pressing force of the linear pattern can be controlled to reduce the probability of curling of the lug after pressing. In addition, since the pattern complexity of the polygonal pattern is higher, the strength of the lug after pressing can be further improved.

[0020] In the above implementation process, since the raised parts of the dot pattern and the sunken parts of the line pattern are arranged relatively to each other, and the sunken parts of the dot pattern and the raised parts of the line pattern are arranged relatively to each other, it can be ensured that the raised parts of the dot pattern and the raised parts of the line pattern can be pressed to both sides of the ear respectively, so as to increase the complexity of the pressed pattern, thereby further improving the strength of the ear after pressing.

[0024] In the above implementation process, since the raised parts of the dot pattern and the sunken parts of the polygonal pattern are arranged relatively to each other, and the sunken parts of the dot pattern and the raised parts of the polygonal pattern are arranged relatively to each other, it can be ensured that the raised parts of the dot pattern and the raised parts of the polygonal pattern can be pressed to both sides of the pole ear respectively. Compared with the pressing method of a single-sided rib wheel, the strength of the pole ear after pressing can be further improved, and the probability of deformation, wrinkling and the like of the pole ear can be better reduced.

[0025] Optionally, in an embodiment of the present application, the first reinforcement rib pattern includes a linear pattern, and the second reinforcement rib pattern includes a polygonal pattern; wherein the first pressing wheel and the second pressing wheel are configured to press the two sides of the pole lug based on the protrusions of the linear pattern and the depressions of the polygonal pattern during the passage of the pole lug, and to press the two sides of the pole lug based on the depressions of the linear pattern and the protrusions of the polygonal pattern.

[0026] In the above-mentioned implementation process, since the raised parts of the linear pattern and the sunken parts of the polygonal pattern are arranged relatively to each other, and the sunken parts of the linear pattern and the raised parts of the polygonal pattern are arranged relatively to each other, it can be ensured that the raised parts of the linear pattern and the raised parts of the polygonal pattern can be pressed to both sides of the pole ear respectively, and based on the polygonal pattern, the strength of the pole ear after pressing can be better improved, so as to better reduce the probability of the occurrence of deformation, wrinkles and the like of the pole ear.

[0027] Optionally, in an embodiment of the present application, the first reinforcement rib pattern and the second reinforcement rib pattern have the same pattern type, and the first pressing wheel and the second pressing wheel are relatively arranged on both sides of the pole ear to be pressed; wherein, the first pressing wheel and the second pressing wheel are configured to press the two sides of the pole ear based on the protrusions of the first reinforcement rib pattern and the depressions of the second reinforcement rib pattern during the passage of the pole ear, and to press the two sides of the pole ear based on the depressions of the first reinforcement rib pattern and the protrusions of the second reinforcement rib pattern; the pattern types include: dot patterns, line patterns or polygonal patterns.

[0028] In the above-mentioned implementation process, when the texture types of the first reinforcing rib pattern and the second reinforcing rib pattern are consistent, the two sides of the pole ear are pressed based on the protrusions of the first reinforcing rib pattern and the recessed parts of the second reinforcing rib pattern, and the two sides of the pole ear are pressed based on the recessed parts of the first reinforcing rib pattern and the protrusions of the second reinforcing rib pattern; it can be ensured that the protrusions of the first reinforcing rib pattern and the protrusions of the second reinforcing rib pattern can be pressed to both sides of the pole ear respectively, so as to improve the strength of the pole ear based on the first reinforcing rib pattern and the second reinforcing rib pattern, and reduce the probability of deformation, wrinkling and other phenomena of the pole ear.

[0041] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0042] Please refer to Figure 1 , Figure 1 A schematic diagram of a pressed structure 01 provided in an embodiment of the present application. The pressed structure 01 comprises: a first pressing wheel 10 and a second pressing wheel 20; the outer surface of the first pressing wheel 10 is provided with a first reinforcing rib pattern, and the outer surface of the second pressing wheel 20 is provided with a second reinforcing rib pattern;

[0043] The first pressing wheel 10 is disposed on one side of the tab to be pressed, and the first pressing wheel 10 is configured to press one side of the tab during the tab passes through;

[0044] The second pressing wheel 20 is disposed on the other side of the pole lug, and the second pressing wheel 20 is configured to press the other side of the pole lug during the passage of the pole lug.

[0045] The first pressing wheel 10 (ignoring the first reinforcing rib pattern on the outer surface) and the second pressing wheel 20 (ignoring the second reinforcing rib pattern on the outer surface) can be arranged in a cylindrical shape as a whole. The first pressing wheel 10 can be made of copper, stainless steel or other materials with greater hardness, and the second pressing wheel 20 can also be made of copper, stainless steel or other materials with greater hardness. The material of the second pressing wheel 20 can be the same as or different from the material of the first pressing wheel 10, and this application does not make specific restrictions on this. It should be noted that the difference in hardness between the material of the first pressing wheel 10 and the material of the second pressing wheel 20 should not be too large.

[0046] The first reinforcing rib pattern or the second reinforcing rib pattern may be a dot pattern, or a line pattern, a polygonal pattern (a triangular pattern, a quadrilateral pattern, or a hexagonal pattern, etc.), or other irregular patterns (e.g., a combined pattern). The polygonal pattern may be a regular polygonal pattern, or other irregular polygons; it may be a convex polygon, or a concave polygon, which is not limited in this application. The pattern types of the first reinforcing rib pattern and the second reinforcing rib pattern may be the same or different.

[0047] The first pressing wheel 10 and the second pressing wheel 20 can be used to press the two sides of the tab during the tab passes through, so as to simultaneously press the first reinforcing rib pattern and the second reinforcing rib pattern to the two sides of the tab. The first pressing wheel 10 can also be used to press the first reinforcing rib pattern to one side of the tab during the tab passes through the first roller; and the second pressing wheel 20 can be used to press the second reinforcing rib pattern to the other side of the tab during the tab passes through the second roller. It is understandable that Figure 1 The positional relationship between the first pressing wheel 10, the second pressing wheel 20 and the "ear tab to be pressed" in the process of passing through the two pressing wheels is only schematically shown; the specific placement positions of the first pressing wheel 10 and the second pressing wheel 20 can be adjusted according to actual conditions. Figure 1 It specifically shows that the first reinforcement rib pattern is realized by a linear pattern, the second reinforcement rib pattern is realized by a polygonal pattern (triangular pattern), and "the first pressing wheel 10 and the second pressing wheel 20 can be used to press both sides of the pole ear during the passage of the pole ear, so as to simultaneously press the first reinforcement rib pattern and the second reinforcement rib pattern to both sides of the pole ear respectively."

[0048] It can be seen that the pressing structure provided in the embodiment of the present application includes a first pressing wheel 10 and a second pressing wheel 20; and the outer surface of the first pressing wheel 10 is provided with a first reinforcing rib pattern, and the outer surface of the second pressing wheel 20 is provided with a second reinforcing rib pattern. Since the first pressing wheel 10 and the second pressing wheel 20 are respectively arranged on both sides of the pole ear to be pressed, one side of the pole ear can be pressed based on the first pressing wheel 10, and the other side of the pole ear can be pressed based on the second pressing wheel 20 during the passage of the pole ear, and the first reinforcing rib pattern and the second reinforcing rib pattern can be pressed on both sides of the pole ear respectively. Compared with the existing unilateral pressing rib treatment method, the pressing structure provided by the present application can further improve the strength of the pole ear, thereby reducing the probability of deformation, wrinkles and other phenomena of the pole ear. The technical problem of how to further improve the strength of the pole ear and reduce the probability of deformation, wrinkles and other phenomena of the pole ear is solved.

[0049] In some optional embodiments, the pattern types of the first reinforcing rib pattern and the second reinforcing rib pattern are inconsistent.

[0050] The first reinforcing rib pattern and the second reinforcing rib pattern have inconsistent pattern types, which means that the pattern types of the first reinforcing rib pattern and the second reinforcing rib pattern are not completely consistent. Exemplarily, when the first reinforcing rib pattern is implemented by a dot pattern, the second reinforcing rib pattern can be implemented by a line pattern, a polygonal pattern, a combination pattern (which can be a combination pattern of a dot pattern and a polygonal pattern), etc. The first reinforcing rib pattern and the second reinforcing rib pattern can be implemented by a combination pattern at the same time, as long as the combination pattern of the first reinforcing rib pattern is not completely consistent with the combination pattern of the second reinforcing rib; for example, when the first reinforcing rib pattern is implemented by a "combination pattern of a triangle pattern and a linear pattern", the second reinforcing rib pattern can be implemented by a "combination pattern of a dot pattern and a linear pattern".

[0051] Please refer to Figure 2 , Figure 2 A schematic structural diagram of a second pressed structural member 02 provided in an embodiment of the present application. Figure 2 Specifically, the situation is shown that "when the tab passes through the first roller, the first reinforcing rib pattern is pressed to one side of the tab based on the first pressing wheel 10; when the tab passes through the second roller, the second reinforcing rib pattern is pressed to the other side of the tab based on the second pressing wheel 20". It can be understood that Figure 2 The positional relationship among the first pressing wheel 10, the second pressing wheel 20, the first passing roller and the second passing roller is only shown by way of example, and the specific implementation of the first reinforcing rib pattern and the second reinforcing rib pattern is not shown.

[0056] In some optional embodiments, the first reinforcement rib pattern includes a linear pattern, and the second reinforcement rib pattern includes a polygonal pattern; wherein the first pressing wheel 10 is configured to press one side of the pole lug based on the linear pattern when the pole lug passes through the first roller; and the second pressing wheel 20 is configured to press the other side of the pole lug based on the polygonal pattern when the pole lug passes through the second roller.

[0057] Among them, in the process of the pole ear passing through the first roller, the linear pattern can be pressed to one side of the pole ear based on the first pressing wheel 10; and in the process of the pole ear passing through the second roller, the polygonal pattern can be pressed to the other side of the pole ear based on the second pressing wheel 20; thereby increasing the complexity of the patterns on both sides of the pressed pole ear, so as to further improve the strength of the pressed pole ear and better reduce the probability of deformation, wrinkles and other phenomena of the pole ear.

[0058] In some optional embodiments, the first pressing wheel 10 and the second pressing wheel 20 are relatively arranged on both sides of the pole ear to be pressed; the first pressing wheel 10 and the second pressing wheel 20 are configured to press both sides of the pole ear during the passage of the pole ear.

[0059] Among them, the raised part of the first reinforcing rib pattern and the sunken part of the second reinforcing rib pattern can be arranged opposite to each other, and the sunken part of the first reinforcing rib pattern and the raised part of the second reinforcing rib pattern can be arranged opposite to each other; and then the two sides of the above-mentioned pole ear can be pressed based on the raised part of the first reinforcing rib pattern and the sunken part of the second reinforcing rib pattern, and the two sides of the pole ear can be pressed based on the sunken part of the first reinforcing rib pattern and the raised part of the second reinforcing rib pattern.

[0060] Please refer to Figure 3 , Figure 3This is a schematic structural diagram of a third type of pressed structural member 03 provided in an embodiment of the present application.

[0061] In some optional embodiments, when the first reinforcing rib pattern includes a dot pattern and the second reinforcing rib pattern includes a line pattern, the protrusions of the dot pattern and the depressions of the line pattern are arranged opposite to each other, and the depressions of the dot pattern and the protrusions of the line pattern are arranged opposite to each other; wherein the first pressing wheel 10 and the second pressing wheel 20 are configured to press the two sides of the pole lug based on the protrusions of the dot pattern and the depressions of the line pattern during the passage of the pole lug, and to press the two sides of the pole lug based on the depressions of the dot pattern and the protrusions of the line pattern.

[0062] The dot pattern can be a cylindrical dot pattern or a hemispherical dot pattern; specifically, the height of the cylindrical shape or the radius of the hemispherical shape can be adjusted according to the actual application, and this application does not make specific restrictions on this. The line pattern can be a straight line pattern or a curved or broken line line pattern; specifically, the cross section of the line pattern can be a semicircle, a rectangle, a trapezoid or other reasonable shapes. Figure 3 The figure shows that the first reinforcing rib pattern is realized by a dot pattern and the second reinforcing rib pattern is realized by a line pattern. The convex part of the dot pattern and the concave part of the line pattern are arranged relative to each other, which means that in the process of pressing the tab based on the first pressing wheel 10 and the second pressing wheel 20, the convex part of the dot pattern and the concave part of the line pattern can act on both sides of the tab at the same time; the concave part of the dot pattern and the convex part of the line pattern are arranged relative to each other, which means that in the process of pressing the tab based on the first pressing wheel 10 and the second pressing wheel 20, the concave part of the dot pattern and the convex part of the line pattern can act on both sides of the tab at the same time; in this way, it is ensured that "in the process of the tab passing through, the convex part of the dot pattern and the concave part of the line pattern can press both sides of the tab based on the concave part of the dot pattern and the convex part of the line pattern".
