When electrode sheets with different widths are required to be embossed, adjustment can be performed by means of the adjustment mechanism (150), such that a distance between a first front embossing roller (121) and a second front embossing roller (122) and a distance between a first rear embossing roller (131) and a second rear embossing roller (132) are matched with the width of each electrode sheet, thereby embossing the electrode sheets with different widths. Moreover, the first front embossing roller (121) and the first rear embossing roller (131) can remain synchronized and maintain the relative position fixed under the action of the first connecting rod (140), and the second front embossing roller (122) and the second rear embossing roller (132) can also remain synchronized and maintain the relative position fixed under the action of the second connecting rod (142). In this way, the adjustment mechanism (150) can adjust the front rolling mechanism (120) and the rear rolling mechanism (130) at the same time, so that the number of operations can be reduced, and the operation difficulty can also be reduced.

Description

Electrode embossing device

[0001] This patent application claims priority to Chinese Patent Application No. 202420992748.3, filed on May 9, 2024, entitled “Electrode Embossing Device”, which is incorporated herein by reference in its entirety. Technical Field

[0002] This application relates to the field of lithium battery equipment technology, and in particular to an electrode embossing device. Background Technology

[0003] Electrodes are the core components in lithium-ion battery manufacturing, made by coating copper or aluminum foil with a paste. The paste is applied to the center of the foil, leaving the sides blank. Die-cutting these blank areas yields the electrode tabs. During transport, the die-cut tabs may fold or deform, potentially causing short circuits within the battery and severely impacting product quality. Therefore, before die-cutting, the blank areas are typically embossed to create reinforcing ribs, increasing the tab's structural strength. Common embossing equipment can only emboss electrodes of specific widths. Since the widths of electrodes used in different lithium-ion battery models vary, embossing equipment cannot be shared, leading to higher equipment costs. Summary of the Invention

[0004] Therefore, it is necessary to provide an electrode embossing device that can emboss electrodes of different widths to address the above problems.

[0005] An electrode embossing device, comprising:

[0006] support;

[0007] The front roller pressing mechanism includes a first front embossing roller and a second front embossing roller that are slidably mounted on the bracket along the direction of rotation.

[0008] A rear roller pressing mechanism, located downstream of the front roller pressing mechanism, includes a first rear embossing roller and a second rear embossing roller slidably mounted on the bracket along the rotation axis. The first front embossing roller and the first rear embossing roller are connected by a first connecting rod, and the second front embossing roller and the second rear embossing roller are connected by a second connecting rod.

[0009] The adjustment mechanism can adjust the distance between the first front embossing roller and the second front embossing roller, and between the first rear embossing roller and the second rear embossing roller.

[0010] In one embodiment, the first surface of the electrode sheet passing through the front and rear roller pressing mechanisms faces the first and second front embossing rollers, and the opposite second surface faces the first and second rear embossing rollers.

[0011] In one embodiment, the roller surfaces of the first front embossing roller and the second front embossing roller are distributed with dot-shaped protrusions, and the roller surfaces of the first rear embossing roller and the second rear embossing roller are distributed with strip-shaped protrusions.

[0012] In one embodiment, the front roller pressing mechanism further includes a front guide roller for supporting the electrode sheet. The front guide roller is disposed opposite to the first front embossing roller and the second front embossing roller, and forms a front embossing channel for the electrode sheet to pass through between the first front embossing roller and the second front embossing roller, respectively.

[0013] In one embodiment, the rear roller pressing mechanism further includes a rear guide roller for supporting the electrode sheet. The rear guide roller is disposed opposite to the first rear embossing roller and the second rear embossing roller, and forms a rear embossing channel for the electrode sheet to pass through between the first rear embossing roller and the second rear embossing roller, respectively.

[0014] In one embodiment, the front guide roller is located below the first front embossing roller and the second front embossing roller, and the rear guide roller is located above the first rear embossing roller and the second rear embossing roller.

[0015] In one embodiment, the adjustment mechanism includes a first adjustment component and a second adjustment component, wherein the first adjustment component is drivenly connected to the first front embossing roller and the first rear embossing roller, and the second adjustment component is drivenly connected to the second front embossing roller and the second rear embossing roller.

[0016] In one embodiment, the first adjustment assembly includes a first lead screw, a first threaded seat, and a first handwheel. The first lead screw is rotatably mounted on the bracket. The first threaded seat is connected to and screwed onto either the first front embossing roller or the first rear embossing roller. The first handwheel is mounted on one end of the first lead screw.

[0017] In one embodiment, the second adjustment assembly includes a second lead screw, a second threaded seat, and a second handwheel. The second lead screw is rotatably mounted on the bracket. The second threaded seat is connected to and screwed onto either the second front embossing roller or the second rear embossing roller. The second handwheel is mounted on one end of the second lead screw.

[0018] In one embodiment, both the first link and the second link are equipped with a correction sensor.

[0019] The aforementioned electrode embossing device can be adjusted via an adjustment mechanism when embossing electrodes of different widths. This adjustment ensures that the distances between the first and second front embossing rollers and between the first and second rear embossing rollers match the width of the electrode, thus enabling embossing of electrodes of varying widths. Furthermore, the first and second front and rear embossing rollers maintain synchronization and a fixed relative position under the action of the first connecting rod, and the second front and rear embossing rollers also maintain synchronization and a fixed relative position under the action of the second connecting rod. In this way, the adjustment mechanism can simultaneously adjust both the front and rear roller pressing mechanisms, thereby reducing the number of operations and lowering the operational difficulty.

[0033] Please refer to Figures 1 and 2. In the preferred embodiment of this application, the electrode embossing device 100 includes a bracket 110, a front roller pressing mechanism 120, a rear roller pressing mechanism 130, a first connecting rod 141, a second connecting rod 142, and an adjustment mechanism 150.

[0034] The bracket 110 provides support, and both the front rolling mechanism 120 and the rear rolling mechanism 130 are mounted on the bracket 110, with the rear rolling mechanism 130 located downstream of the front rolling mechanism 120. The electrode sheet 200 to be processed (see Figure 4) passes sequentially through the front rolling mechanism 120 and the rear rolling mechanism 130. The front rolling mechanism 120 performs a first embossing on the blank areas on both sides of the width edge of the electrode sheet 200 to form a first reinforcing rib, and the rear rolling mechanism 130 performs a second embossing on the blank areas on both sides of the width edge of the electrode sheet 200 to form a second reinforcing rib. The first and second reinforcing ribs work together to significantly increase the structural strength of the blank areas.

[0035] The front embossing mechanism 120 includes a first front embossing roller 121 and a second front embossing roller 122, which are slidably mounted on the bracket 110 along the rotation axis. Specifically, the first front embossing roller 121 and the second front embossing roller 122 can be mounted on the bracket 110 via a guide rail slider. The first front embossing roller 121 and the second front embossing roller 122 have the same structure, and their rotation axes are parallel to each other. The first front embossing roller 121 and the second front embossing roller 122 are spaced apart along the rotation axis, and the spacing corresponds to the width of the electrode sheet 200. Therefore, the first front embossing roller 121 and the second front embossing roller 122 can respectively emboss the two blank areas of the electrode sheet 200, thereby achieving the first embossing of the blank areas.

[0036] In this embodiment, the front rolling mechanism 120 further includes a front guide roller 123 for supporting the electrode sheet 200. The front guide roller 123 is disposed opposite to the first front embossing roller 121 and the second front embossing roller 122, and forms a front embossing channel between the front guide roller 123 and the first front embossing roller 121 and the second front embossing roller 122 for the electrode sheet 200 to pass through. The front guide roller 123 is relatively long and can support the electrode sheet 200 as a whole. When the electrode sheet 200 passes through the front rolling mechanism 120, the blank areas on its opposite sides pass through the front embossing channels on both sides, so that the first front embossing roller 121 and the second front embossing roller 122 respectively roll the blank areas on both sides.

[0037] During the process of the first front embossing roller 121 and the second front embossing roller 122 rolling the blank area of ​​the electrode 200, the middle area of ​​the electrode 200 can be effectively supported, thereby preventing the electrode 200 from being concave and deformed, thus ensuring the accuracy of the rolling position.

[0038] The rear roller pressing mechanism 130 has a structure largely the same as the front roller pressing mechanism 120. The rear roller pressing mechanism 130 includes a first rear embossing roller 131 and a second rear embossing roller 132, which are slidably mounted on the bracket 110 along the rotation axis. Specifically, the first rear embossing roller 131 and the second rear embossing roller 132 can be mounted on the bracket 110 via a guide rail slider. The first rear embossing roller 131 and the second rear embossing roller 132 have the same structure, and their rotation axes are parallel to each other. The first rear embossing roller 131 and the second rear embossing roller 132 are spaced apart along the rotation axis, and the spacing corresponds to the width of the electrode sheet 200. Therefore, the first rear embossing roller 131 and the second rear embossing roller 132 can respectively roll the two blank areas of the electrode sheet 200, thereby achieving a second embossing of the blank areas.

[0039] In this embodiment, the rear rolling mechanism 130 further includes a rear guide roller 133 for supporting the electrode sheet 200. The rear guide roller 133 is disposed opposite to the first rear embossing roller 131 and the second rear embossing roller 132, and forms a rear embossing channel between the rear guide roller 133 and the first rear embossing roller 131 and the second rear embossing roller 132 for the electrode sheet 200 to pass through. When the electrode sheet 200 passes through the rear rolling mechanism 130, the blank areas on its opposite sides pass through the rear embossing channels on both sides, so that the first rear embossing roller 131 and the second rear embossing roller 132 respectively roll the blank areas on both sides of the electrode sheet 200.

[0040] The rear guide roller 133 is relatively long and can support the electrode sheet 200 as a whole. During the rolling process of the first rear embossing roller 131 and the second rear embossing roller 132 on the blank area of ​​the electrode sheet 200, the middle area of ​​the electrode sheet 200 can be effectively supported, thereby preventing the electrode sheet 200 from being concave and deformed, and thus ensuring the accuracy of the rolling position.

[0041] Please refer to Figures 3 and 4. The first rear embossing roller 131 is positioned opposite the first front embossing roller 121, and together they can roll one blank area of ​​the electrode sheet. The second rear embossing roller 132 is positioned opposite the first rear embossing roller 131, and together they roll the other blank area of ​​the electrode sheet. Furthermore, the first front embossing roller 121 and the first rear embossing roller 131 are connected by a first connecting rod 141, and the second front embossing roller 122 and the second rear embossing roller 132 are connected by a second connecting rod 142. It can be seen that the relative positions of the first front embossing roller 121 and the first rear embossing roller 131 remain stable, and they can move synchronously. The relative positions of the second front embossing roller 122 and the second rear embossing roller 132 also remain stable, and they can also move synchronously.

[0042] In this embodiment, the first surface of the electrode sheet 200 passing through the front rolling mechanism 120 and the rear rolling mechanism 130 faces the first front embossing roller 121 and the second front embossing roller 122, and the opposite second surface faces the first rear embossing roller 131 and the second rear embossing roller 132.

[0043] As shown in Figure 4, the first surface refers to the upper surface of the electrode 200, and the second surface refers to the lower surface. That is, the front roller pressing mechanism 120 and the rear roller pressing mechanism 130 can respectively emboss two different sides of the blank area of ​​the electrode 200, thus forming the first reinforcing rib and the second reinforcing rib distributed on opposite surfaces of the blank area. This reduces the impact of the second embossing process on the first reinforcing rib formed by the first embossing.

[0044] Specifically, in this embodiment, the front guide roller 123 is located below the first front embossing roller 121 and the second front embossing roller 122, and the rear guide roller 133 is located above the first rear embossing roller 131 and the second rear embossing roller 132. Thus, when the electrode sheet 200 passes through the front rolling mechanism 120, its first surface faces the first front embossing roller 121 and the second front embossing roller 122, and when the electrode sheet 200 passes through the rear rolling mechanism 130, its second surface faces the first rear embossing roller 131 and the second rear embossing roller 132.

[0045] Furthermore, please refer to Figures 5 and 6. In this embodiment, the roller surfaces of the first front embossing roller 121 and the second front embossing roller 122 are distributed with dot-shaped protrusions 1211, and the roller surfaces of the first rear embossing roller 131 and the second rear embossing roller 132 are distributed with strip-shaped protrusions 1311. The dot-shaped protrusions 1211 on the first front embossing roller 121 and the second front embossing roller 122 can form dot-shaped first reinforcing ribs in the blank areas, and the strip-shaped protrusions 1311 on the first rear embossing roller 131 and the second rear embossing roller 132 can form strip-shaped second reinforcing ribs on the surface. The combination of the two types of reinforcing ribs significantly improves the structural strength.

[0046] Please refer again to Figures 1 to 3. The adjusting mechanism 150 can adjust the distance between the first front embossing roller 121 and the second front embossing roller 122, and can also adjust the distance between the first rear embossing roller 131 and the second rear embossing roller 132. When it is necessary to emboss electrode sheets 200 of different widths, the adjusting mechanism 150 can be used to adjust the distance between the first front embossing roller 121 and the second front embossing roller 122, and the distance between the first rear embossing roller 131 and the second rear embossing roller 132, to match the width of the electrode sheet 200, thereby enabling embossing of electrode sheets 200 of different widths.

[0047] Furthermore, since the first front embossing roller 121 and the first rear embossing roller 131 can maintain synchronization and a fixed relative position under the action of the first connecting rod 141, moving either the first front embossing roller 121 or the first rear embossing roller 131 can change the distance between the first front embossing roller 121 and the second front embossing roller 122, as well as between the first rear embossing roller 131 and the second rear embossing roller 132. Similarly, the second front embossing roller 122 and the second rear embossing roller 132 can also maintain synchronization and a fixed relative position under the action of the second connecting rod 142. Therefore, moving either the second front embossing roller 122 or the second rear embossing roller 132 can also change the distance between the first front embossing roller 121 and the second front embossing roller 122, as well as between the first rear embossing roller 131 and the second rear embossing roller 132. In other words, the adjusting mechanism 150 can simultaneously adjust both the front roller pressing mechanism 120 and the rear roller pressing mechanism 130, thereby reducing the number of operations and lowering the difficulty of operation.

[0048] Furthermore, in this embodiment, each of the two first connecting rods 141 and the second connecting rod 142 is equipped with a correction sensor head 160. The two correction sensor heads 160 are used to detect the two blank areas of the electrode 200 to determine whether the electrode 200 has shifted. Since each correction sensor head 160 can move synchronously with its corresponding first connecting rod 141 or second connecting rod 142, it is not necessary to adjust the position of each correction sensor head 160 individually when embossing electrodes 200 of different widths, thereby further reducing the operational difficulty.

[0049] In this embodiment, the adjustment mechanism 150 includes a first adjustment component 151 and a second adjustment component 152. The first adjustment component 151 is drivenly connected to the first front embossing roller 121 and the first rear embossing roller 131, and the second adjustment component 152 is drivenly connected to the second front embossing roller 122 and the second rear embossing roller 132.

[0050] The first adjustment component 151 can drive the first front embossing roller 121 and the first rear embossing roller 131 to slide synchronously, thereby adjusting the distance between the first front embossing roller 121 and the second front embossing roller 122, and between the first rear embossing roller 131 and the second rear embossing roller 132. The second adjustment component 152 can drive the second front embossing roller 122 and the second rear embossing roller 132 to slide synchronously, and can also adjust the distance between the first front embossing roller 121 and the second front embossing roller 122, and between the first rear embossing roller 131 and the second rear embossing roller 132. Therefore, when adjusting the front roller pressing mechanism 120 and the rear roller pressing mechanism 130, each blank area of ​​the electrode sheet 200 can be aligned individually, resulting in higher adjustment accuracy.

[0051] Furthermore, in this embodiment, the first adjustment component 151 includes a first lead screw 1511, a first threaded seat 1512, and a first handwheel 1513. The first lead screw 1511 is rotatably mounted on the bracket 110. The first threaded seat 1512 is connected to any one of the first front embossing roller 121 and the first rear embossing roller 131 and is screwed onto the first lead screw 1511. The first handwheel 1513 is mounted on one end of the first lead screw 1511.

[0052] Specifically, in this embodiment, the first threaded seat 1512 is connected to the first rear embossing roller 131. The first handwheel 1513 drives the first lead screw 1511 to rotate, which in turn causes the first threaded seat 1512 to move along its extension direction, thereby causing the first rear embossing roller 131 to slide, and consequently, the first front embossing roller 121 and its corresponding first connecting rod 141 to move synchronously. The cooperation between the first lead screw 1511 and the first threaded seat 1512 enables high-precision movement, thereby improving adjustment accuracy.

[0053] The structure of the second adjustment component 152 is roughly the same as that of the first adjustment component 151. Specifically, the second adjustment component 152 includes a second lead screw 1521, a second threaded seat 1522, and a second handwheel 1523. The second lead screw 1521 is rotatably mounted on the bracket 110. The second threaded seat 1522 is connected to either the second front embossing roller 122 or the second rear embossing roller 132 and is screwed onto the second lead screw 1521. The second handwheel 1523 is mounted on one end of the second lead screw 1521.

[0054] The aforementioned electrode embossing device 100, when embossing electrodes 200 of different widths is required, can be adjusted via the adjusting mechanism 150 to match the distance between the first front embossing roller 121 and the second front embossing roller 122, and the distance between the first rear embossing roller 131 and the second rear embossing roller 132, with the width of the electrode 200. This enables embossing of electrodes 200 of different widths. Furthermore, the first front embossing roller 121 and the first rear embossing roller 131 can maintain synchronization and a fixed relative position under the action of the first connecting rod 141, and the second front embossing roller 122 and the second rear embossing roller 132 can also maintain synchronization and a fixed relative position under the action of the second connecting rod 142. Thus, the adjusting mechanism 150 can simultaneously adjust both the front roller pressing mechanism 120 and the rear roller pressing mechanism 130, thereby reducing the number of operations and lowering the operational difficulty.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
