At the same time, as new energy and environmental protection are the mainstream trends of the future, lithium batteries have become an emerging industry strongly promoted by the country. Therefore, the high-efficiency production of lithium batteries, which are both environmentally friendly and high-tech, is of great significance.

[0003] In the lithium-ion battery manufacturing process, the production process for positive and negative electrode sheets includes winding positive / negative electrode sheets, rolling, cutting large sheets, slicing, and stacking. Currently, most die-cutting machines using metal die-cutting technology employ a spring clip receiving device. In existing electrode sheet production, due to limitations in coating technology, the coating amount of the electrode sheets cannot be completely consistent. During the spring clip receiving process in the slicing step, as the longitudinal height accumulates, this difference in coating amount can cause the upper electrode sheet to warp, affecting the quality of the electrode sheet product.

[0004] Utility model patent CN218261128U, published on January 10, 2023, discloses an electrode sheet guide roller and electrode sheet forming device. The electrode sheet guide roller is used to guide the electrode sheet on the conveyor belt. The electrode sheet guide roller includes a first support section and a second support section for supporting the electrode sheet. The first support section and the second support section are arranged along the axial direction of the electrode sheet guide roller. The roller diameter of the first support section gradually decreases in the direction away from the second support section, and the roller diameter of the second support section gradually decreases in the direction away from the first support section. This electrode sheet guide roller and electrode sheet forming device cannot improve the electrode sheet edge warping phenomenon or improve product quality. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-4 An electrode sheet receiving device includes a base plate 1, an electrode sheet is disposed on the top of the base plate 1, and adjusting rods 2 are movably connected to both sides of the base plate 1. Both the base plate 1 and the adjusting rods 2 are provided with transition rounded corners.

[0029] The transition fillet includes a first transition fillet 3 and a second transition fillet 4. The first transition fillet 3 is provided at both ends of the base plate 1, and the second transition fillet 4 is provided at the side end of the middle part of the adjusting rod 2.

[0030] By setting transition rounded corners on the base plate 1 and the adjusting rod 2, the problem of electrode edge warping can be effectively improved, thus enhancing product quality. The adjusting rod 2 is adjustable, and its usage can be adjusted to meet different electrode material conditions, effectively preventing the electrode edge from warping or falling, and improving product yield.

[0031] In the implementation of the case, notches 10 are provided in the middle of both sides of the base plate 1, and the middle part of the adjusting rod 2 is set inside the notch 10, and the middle part of the adjusting rod 2 is adapted to the notch 10.

[0032] The notch 10 on the side of the base plate 1 will not increase the area occupied by the base plate 1, which facilitates the installation of the adjustment rod 2. When the adjustment rod 2 is rotated to the bottom of the base plate 1, the design of the notch 10 makes the first transition fillet 3 and the second transition fillet 4 aligned in the same direction, ensuring that the edges of the electrode sheet fall neatly on the transition fillet when it is placed, and avoiding the edge warping of the electrode sheet.

[0033] In the implementation of the case, a first mounting hole 7 is provided at one end of the base plate 1, a threaded hole 9 is provided on the inner side of the notch 10, and a second mounting hole 8 is provided on the adjusting rod 2. The adjusting rod 2 and the base plate 1 are connected by bolts. The bolts pass through the interior of the first mounting hole 7 and the second mounting hole 8 and extend to the interior of the threaded hole 9 for threaded connection. The first mounting hole 7 is a stepped hole.

[0034] The head of the bolt is installed inside the base plate 1 without affecting the flatness of the end of the base plate 1. The adjusting rod 2 and the base plate 1 are connected by bolts, so that the adjusting rod 2 can be adjusted to rotate. If the edge of the incoming electrode sheet is falling, the adjusting rod 2 can be adjusted to the top of the base plate 1. The adjusting rod 2 can lift the edge of the electrode sheet to the position where it is falling, so that the edge of the electrode sheet is neat and flat.

[0035] In the implementation of the case, a positioning hole 5 is provided in the middle of the base plate 1. The positioning hole 5 has a rectangular structure.

[0036] During operation, the bottom of the base plate 1 is equipped with a lifting mechanism, which can lift the base plate 1. The push rod of the lifting mechanism has a protrusion that is positioned with the positioning hole 5 of the base plate 1, which can make the base plate 1 more stable during operation. The positioning hole 5 is designed as a rectangular structure to match the protrusion on the push rod, which can further enhance the stability of the base plate 1 during operation.

[0037] In the implementation of the case, the length of the adjusting rod 2 is matched with the length of the base plate 1.

[0038] By adapting the base plate 1 to the shape and structure of the electrode sheet, when it is necessary to rotate the adjusting rod 2 to the upper part of the base plate 1, the length of the adjusting rod 2 is the same as the length of the base plate 1, which can completely lift the edge of the electrode sheet and prevent the edge of the electrode sheet from falling.

[0039] In the implementation of the case, a protrusion 6 was installed on one end of the base plate 1.

[0040] By adapting the base plate 1 and protrusion 6 to the shape and structure of the electrode sheet, the electrode sheet to be processed can be laid flat on the base plate 1.

[0041] In the implementation of this case, base plate 1 is made of special aluminum alloy.

[0042] The base plate 1 is made of special aluminum alloy material and the surface is sandblasted, which improves the mechanical properties of the base plate 1 surface, enhances the fatigue resistance and durability of the base plate 1, and extends the service life of the base plate 1.

[0043] In the implementation of the case, the first transition fillet 3 covers the ends of both sides of the base plate 1, and the second transition fillet 4 covers the middle side of the adjusting rod 2.

[0044] When the adjusting rod 2 is rotated to the bottom of the base plate 1, the first transition fillet 3 and the second transition fillet 4 come into contact with the edge of the electrode sheet, so that the edge of the electrode sheet is in a downward state, which can effectively improve the edge warping of the electrode sheet.

[0045] When implementing this procedure, please follow these steps:

[0046] 1) First, select a base plate 1 of appropriate size according to the usage requirements, and place the base plate 1 in the designated working position;

[0047] 2) Then adjust the position of the adjusting rod 2. If the edge of the incoming electrode sheet is upturned, adjust the adjusting rod 2 to the bottom of the base plate 1.

[0048] 3) If the edge of the incoming electrode sheet is drooping, adjust the adjusting rod 2 to the top of the base plate 1. After adjusting the adjusting rod 2 according to the incoming electrode sheet, place the electrode sheet to be processed on the base plate 1.

[0049] 4) Then start the equipment. A lifting mechanism is provided under the base plate 1. The push rod of the lifting mechanism is positioned and engaged with the positioning hole 5 in the middle of the base plate 1 to ensure that the base plate 1 is stable during operation. The lifting mechanism starts the push rod to lift the base plate 1. The electrode plates stacked on the base plate 1 also move upward with the base plate 1 until they are pressed against the pressing mechanism at the top of the worktable.

[0050] 5) Finally, the push rod moves down, the base plate 1 returns to the initial position, and the electrode sheet completes the stacking process.

[0051] In summary, the electrode sheet receiving device of this invention has a compact and reasonable structural design, is simple and convenient to use, and the adjustment rod connected to the base plate can adjust the edge of the electrode sheet. The transition rounded corners on the base plate and the adjustment rod can effectively improve the edge warping of the electrode sheet. By adjusting the position of the adjustment rod, the edge warping and falling of the electrode sheet can be improved, which can significantly improve the product quality.

[0052] Furthermore, by using a rounded corner, when the electrode edge is upturned, during the operation of the device, the electrode is affected by its own weight during the take-up process. The rounded corner can cause the electrode edge to be in a sunken state at the rounded corner, thereby avoiding the upturning of the electrode edge.
