[0029] In order to enable ordinary people in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0030] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0031] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for display, data for analysis, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties.

[0032] like Figure 1 As can be seen from the middle BC section, the cutting speed is mainly limited by the bevel of the tab. When the tab height increases, the cutting speed also increases accordingly. The speed increase of the laser die-cutting equipment at this stage has reached a bottleneck. If the cutting speed continues to increase, the stability of the equipment will not be guaranteed. Based on this, the embodiment of the present application provides a tab forming method, such as Figure 2 As shown, the method includes the following steps:

[0033] S201: moving the material strip along a preset path;

[0034] In an embodiment of the present application, by moving the material strip along a preset path, the material strip can be made to reach a first cutting position and a second cutting position, so as to perform laser cutting on the material strip, thereby forming tabs on the material strip.

[0035] In the embodiments of this application, Figure 3 As shown, the first cutting position may be provided with a first laser cutting assembly, and the second cutting position may be provided with a second laser cutting assembly.

[0036] In the embodiments of this application, Figure 3 As shown, the preset path can be from right to left, that is, the material strip can be moved from right to left. Of course, the preset path can also be set to be from left to right, or other forms of paths, and this application does not limit this.

[0037] S203: When the material strip moves to the first cutting position, laser cutting is performed on the material strip to form at least one first cutting line on the material strip, where the first cutting line forms a first height area of ​​the tab;

[0038] In the embodiment of the present application, when the material strip moves along a preset path, it moves to a first cutting position. At the first cutting position, the material strip can be laser cut using a first laser cutting assembly located at the first cutting position. By laser cutting, a first cutting line can be formed on the material strip, and the first cutting line can enclose a first height area of ​​the tab.

[0039] For example, Figure 4 As shown, the material strip passes through the first laser cutting assembly and is laser cut to form a first cutting line C'CDD' on the material strip, and the first cutting line C'CDD' surrounds the upper half of the tab.

[0040] It should be noted that if Figure 4 As shown in FIG, since this step only requires cutting out a shape similar to a "C" with the opening facing downward, as shown in FIG. Figure 4 As shown by the middle dotted line, the first laser cutting assembly follows the track during the strokes MC' and D'-N, but does not emit laser light.

[0041] S205: When the material strip moves to the second cutting position, laser cutting is performed on the material strip to form a second cutting line on the material strip for connecting with the first cutting line, wherein the second cutting line forms a second height area of ​​the tab;

[0042] In the embodiment of the present application, after the first height region of the tab is formed on the material strip, the material strip may continue to move forward to reach a second cutting position.

[0043] In an embodiment of the present application, determining that the material strip moves to the second cutting position may include: after the material strip completes laser cutting at the first cutting position, monitoring the movement of the material strip toward the second cutting position; when the movement time is a preset movement time or the movement distance is a preset movement distance, determining that the material strip moves to the second cutting position.

[0044] Specifically, an encoder (not shown) may be provided during the advancement of the material strip, and the encoder is used to capture the position of the material strip. The installation positions and distances of the first laser cutting assembly and the second laser cutting assembly are relatively fixed. After the first laser cutting assembly completes partial cutting of the tab, the time for the partially cut tab to reach the second laser cutting assembly is calculated. When the moving time is the preset moving time, it is determined that the material strip moves to the second cutting position, wherein the preset moving time can be predetermined based on the distance between the first laser cutting assembly and the second laser cutting assembly and the running speed of the material strip. Alternatively, the moving distance of the material strip is calculated based on the moving time and the moving speed of the material strip, and when the moving distance of the material strip is the preset moving distance, it is determined that the material strip moves to the second cutting position.

[0045] In an embodiment of the present application, after reaching the second cutting position, the material strip can be further laser cut using a second laser cutting assembly located at the second cutting position. Through laser cutting, a second cutting line connected to the first cutting line can be formed on the material strip, wherein the second cutting line can enclose a second height area of ​​the tab.

[0046] For example, Figure 4 As shown, the material strip passes through the second laser cutting assembly and is cut by laser to form two second cutting lines ABC' and D'EF on the material strip. The two second cutting lines ABC' and D'EF surround the lower half of the tab. Figure 5 and Figure 6 As shown, since the endpoint C' of the second cutting line ABC' is connected to the endpoint C' of the first cutting line C'CDD', and the endpoint D' of the second cutting line D'EF is connected to the endpoint D' of the first cutting line C'CDD', the upper half of the tab surrounded by the first cutting line C'CDD' and the lower half of the tab surrounded by the second cutting lines ABC' and D'EF together constitute the tab.

[0047] It should be noted that if Figure 4 As shown by the middle dotted line, during the stroke C'-D', the second laser cutting assembly follows the track but does not emit laser light to avoid cutting the tab into two parts.

[0048] Furthermore, the present embodiment uses the example of splitting the tab in half, but in practice this is not a requirement. If the tab is not split in half from the middle, it is sufficient to ensure that the total tab height is equal to the sum of the heights of the first height region and the second height region (assuming the first height region and the second height region do not overlap), and to simultaneously control the sections where the two laser cutting assemblies emit laser light and the sections where they do not.

[0049] In the embodiment of the present application, the time required for the laser to travel each section during laser cutting is the same as the time required for the laser to cut the corresponding cutting line on the material strip.

[0050] For example, the time required for the second laser cutting assembly to travel the AB segment is the same as the time required to cut the AB segment of the tab on the strip, the time required for the second laser cutting assembly to travel the BC' segment is the same as the time required to cut the BC' segment on the strip, and so on. In other words, the time required for the second laser cutting assembly to complete the "8" shape of ABC'D'EF is the same as the time required for the strip AF to travel. Assuming that the strip speed V is constant, the total length Z of the strip traveled divided by the strip speed V is the total time. The total time the strip travels is the same as the total time required for the second laser cutting assembly to complete the "8" trajectory. The cutting speed of each segment can be different.

[0051] In an embodiment of the present application, the width of the tab is greater than the travel distance of the laser when cutting in the width direction of the tab during laser cutting.

[0052] For example, the width of the tab (i.e., the length of the CD segment) must be longer than the CD segment stroke in the "8"-shaped trajectory of the first laser cutting component, otherwise it will not be possible to cut. This is because during the cutting process, the material strip itself is also moving forward, and the width of the tab is composed of the stroke length of the first laser cutting component and the distance the material strip moves forward. In an embodiment of the present application, the first height area of ​​the tab can be the upper part of the tab, and the second height area of ​​the tab can be the lower part of the tab. Of course, the first height area of ​​the tab can also be the lower part of the tab, and the second height area of ​​the tab can also be the upper part of the tab. That is, it is acceptable to cut the upper part of the tab first or the lower part of the tab first, and this application does not impose any restrictions on this.

[0053] In the embodiment of the present application, since the tab is made of a relatively thin material and requires sufficient support, the preferred method is to cut the upper portion of the tab first, followed by the lower portion. That is, when the first cutting position is upstream of the second cutting position, the first height region at the free end of the tab is preferentially cut.

[0054] In the embodiment of the present application, the first height region and the second height region may partially overlap along the height direction of the tab.

[0055] In actual application, the first height area and the second height area partially overlap along the height direction of the tab, which can ensure that the first cutting line formed by the second laser cutting component cutting the material strip is reliably connected with the second cutting line formed by the first laser cutting component cutting the material strip.

[0056] Furthermore, the end of the first cutting line close to the second cutting line can be an arc or an oblique line, and the second cutting line intersects with the arc or oblique line of the first cutting line; and / or, the end of the second cutting line close to the first cutting line can also be an arc or an oblique line, and the first cutting line intersects with the arc or oblique line of the second cutting line.

[0057] For example, the first laser cutting assembly cuts the material strip to form a first cutting line C'CDD', wherein a circular arc or oblique line is provided at C' or D'. The second laser cutting assembly cuts the material strip to form a second cutting line ABC' and D'EF, wherein a circular arc or oblique line is provided at C' or D'.

[0058] In this way, it can be further ensured that the first cutting line formed by the second laser cutting assembly cutting the material strip is reliably connected with the second cutting line formed by the first laser cutting assembly cutting the material strip.

[0059] S207: Continue moving the material strip along the preset path.

[0060] In an embodiment of the present application, continuing to move the material strip along the preset path (i.e., step S207) may include: after completing the laser cutting of the pole ear on the material strip, continuing to move the pole piece with the pole ear along the preset path, and transporting the pole piece to the winding assembly.

[0061] Specifically, the tabs can be laser cut at the first cutting position and the second cutting position respectively. After the laser cutting is finally completed, the pole piece with the tabs formed thereon can be rolled up by a rolling assembly.

[0062] In the embodiment of the present application, the tab may be Figure 3 The rectangle shown can also be a trapezoid (such as Figure 6 as shown), a square or a polygon with chamfered corners, etc.

[0063] It should be noted that the tab can be formed by only two laser cuts, or by more laser cuts. For example, in some embodiments, step S207 may further include: continuing to move the material strip along the preset path to a third cutting position, laser cutting the material strip using a third laser cutting assembly, forming a third cutting line on the material strip that is connected to the second cutting line, wherein the third cutting line forms a third height region of the tab. That is, the tab cutting in the embodiments of the present application is not limited to only two laser cuts.

[0064] In an embodiment of the present application, two laser cutting assemblies can be set up at a die-cutting station, one for cutting the upper half of the tab and the other for cutting the lower half of the tab, and used in combination to reduce the power requirements of each device.

[0065] Furthermore, through the embodiments of the present application, if laser cutting is performed at a certain tape speed, the power requirement for the laser is reduced compared to the prior art; if laser cutting is performed at a certain laser power, the tape speed can be increased.
