In order to make the technical solutions of the present application better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be implemented in sequences other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims.

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 for presentation, analyzed data, etc.) referred to in the present application are both information and data authorized by the user or sufficiently authorized by each party.

As can be seen from the BC section in fig. 1, the cutting speed is mainly limited by the bevel edge portion of the tab, when the height of the tab is increased, the cutting speed is correspondingly increased, the speed of the laser die cutting equipment in the current stage is increased to reach a bottleneck, and if the cutting speed is continuously increased, the stability of the equipment cannot be guaranteed. Based on this, the embodiment of the present application provides a tab forming method, as shown in fig. 2, the method includes the following steps:

s201: moving the strip along a preset path;

in this application embodiment, through moving the material area along preset route, can make the material area reach first cutting position and second cutting position to carry out laser cutting to the material area, thereby form utmost point ear on the material area.

In the embodiment of the present application, as shown in fig. 3, 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.

In the embodiment of the present application, as shown in fig. 3, the preset path may be from right to left, that is, the tape may be moved from right to left. Of course, the preset path may also be set from left to right, and may also be other types of paths, which is not limited in this application.

S203: when the material belt moves to a first cutting position, carrying out laser cutting on the material belt, and forming at least one section of first cutting line on the material belt, wherein the first cutting line forms a first height area of a lug;

in the embodiment of the application, when the material belt moves along the preset path, the material belt moves to the first cutting position. The first cutting position can utilize the first laser cutting assembly located in the first cutting position to carry out laser cutting on the material belt, through laser cutting, a first cutting line can be formed on the material belt, and the first cutting line can be enclosed into a first height area of the tab.

For example, as shown in fig. 4, the strip of material passes through the first laser cutting assembly, and after laser cutting, a first cutting line C 'CDD' may be formed on the strip of material, and the first cutting line C 'CDD' encloses the upper half portion of the tab.

It should be noted that, as shown in fig. 4, since this step only requires cutting a shape like a "C" with the opening facing downward, the first laser cutting assembly does not emit laser light although it traces the path at the strokes M-C 'and D' -N, as shown by the dotted line in fig. 4.

S205: when the material belt moves to a second cutting position, the material belt is subjected to laser cutting, a second cutting line used for being connected with the first cutting line is formed on the material belt, and a second height area of the lug is formed by the second cutting line;

in this embodiment, after the first height area of the tab is formed on the strip of material, the strip of material may continue to move forward to reach the second cutting position.

In an embodiment of the present application, determining that the strip of material moves to the second cutting position may include: when the material belt is subjected to laser cutting at the first cutting position, monitoring the movement of the material belt towards the second cutting position; and when the moving time is preset moving time or the moving distance is preset moving distance, determining that the material belt moves to the second cutting position.

In particular, an encoder (not shown) may be provided during the advancement of the strip of material, for capturing the position of the strip of material. The installation positions and the distances of the first laser cutting assembly and the second laser cutting assembly are relatively fixed, after the first laser cutting assembly finishes partial cutting of the lug, the time for the lug which is partially cut to reach the second laser cutting assembly is calculated, and when the moving time is preset moving time, the material belt is determined to move to the second cutting position, wherein the preset moving time can be predetermined according to the distance between the first laser cutting assembly and the second laser cutting assembly and the running speed of the material belt. Or calculating the moving distance of the material belt according to the moving time and the moving speed of the material belt, and determining that the material belt moves to the second cutting position when the moving distance of the material belt is a preset moving distance.

In this application embodiment, after reaching the second cutting position, can utilize to be located the second laser cutting subassembly of second cutting position is right the material area continues to carry out laser cutting, through laser cutting, can form on the material area with the second line of cutting that first line of cutting is connected, wherein, the second line of cutting can enclose into the second height region of utmost point ear.

For example, as shown in fig. 4, the material strip passes through the second laser cutting assembly, and is laser cut, two sections of second cutting lines ABC 'and D' EF may be formed on the material strip, and the two sections of second cutting lines ABC 'and D' EF enclose the lower half portion of the tab. As shown in fig. 5 and 6, since the end point C 'of the second cutting line ABC' is connected to the end point C 'of the first cutting line C' CDD 'and the end point D' of the second cutting line D 'EF is connected to the end point D' of the first cutting line C 'CDD', the upper half portion of the tab surrounded by the first cutting line C 'CDD' and the lower half portion of the tab surrounded by the second cutting lines ABC 'and D' EF together constitute the tab.

It should be noted that, as shown by the dotted line in fig. 4, the second laser cutting assembly does not emit laser light although it travels along the path C '-D' during the stroke C '-D', so as to avoid cutting the tab waists into upper and lower sections.

And, the embodiment of the present application explains the half division of the tab, but the half division is not necessarily required in practical application. If the total height of the lug is not half of the total height of the lug from the middle of the lug, the total height of the lug is ensured to be equal to the sum of the height of the first height area and the height of the second height area (on the premise that the first height area and the second height area are not overlapped), and the laser-emitting road sections and the laser-non-emitting road sections of the two laser cutting assemblies are controlled simultaneously.

In the embodiment of the application, the time required by the laser to travel each section of the stroke during laser cutting is the same as the time required by the laser to cut the corresponding cutting line on the material belt.

For example, the time required for the second laser cutting assembly to travel an AB segment travel is the same as the time required to cut an AB segment of a tab on the strip of material, the time required for the second laser cutting assembly to travel a BC 'segment travel is the same as the time required to cut a BC' segment on the strip of material, and so on. That is to say, the time that the second laser cutting assembly finishes walking the 8 shape of ABC 'D' EF is the same as the time that the material belts a-F walk, assuming that the material belt speed V is constant, the total length Z of the material belt that walks is the total time divided by the material belt speed V, and the total time that the material belt walks and the total time that the second laser cutting assembly finishes walking the 8-shaped track are the same. Wherein the cutting speed of each segment may be different.

In the embodiment of the application, the width of the tab is larger than the travel distance of the laser in the cutting process in the width direction of the tab during laser cutting.

For example, the width of the tab (i.e., the length of the CD segment) must be longer than the travel of the CD segment in the "8" shaped track of the first laser cut assembly, otherwise it will not be cut. This is because the material belt advances during the cutting process, and the width of the tab is composed of the stroke length of the first laser cutting assembly and the advancing distance of the material belt. In this embodiment, the first height area of the tab may be an upper portion of the tab, and the second height area of the tab may be a lower portion of the tab. Of course, the first height area of the tab may also be a lower portion of the tab, and the second height area of the tab may also be an upper portion of the tab. That is, the upper portion of the tab or the lower portion of the tab may be cut first, which is not limited in the present application.

In the embodiment of the present application, since the tab is made of a thinner material, in consideration of the need for sufficient support, the preferred method is to cut the upper portion of the tab first, and then cut the lower portion of the tab. That is, the first height region at the free end of the tab will be preferentially cut when the first cutting location is upstream of the second cutting location.

In the embodiment of the present application, the first height region and the second height region may partially overlap in a height direction of the tab.

In practical application, the first height area and the second height area are partially overlapped in the height direction of the lug, so that the second laser cutting assembly can cut a first cutting line formed by the material belt and a second cutting line formed by the first laser cutting assembly are reliably connected.

Further, the end of the first cutting line close to the second cutting line can be a circular arc or an oblique line, and the second cutting line intersects with the circular arc or the oblique line of the first cutting line; and/or, the second cuts the line and is close to the tip that first cuts the line also can be circular arc or slash, first cuts the line with the circular arc or slash of second cuts the line intersect.

For example, the first laser cutting assembly cuts a first cutting line C 'CDD' formed by cutting the material belt, wherein a circular arc or an oblique line is arranged at C 'or D'. The second laser cutting assembly cuts second cutting lines ABC 'and D' EF formed by the material belt, wherein a circular arc or an oblique line is arranged at the position of C 'or D'.

So, can further guarantee the second laser cutting subassembly cuts the first line of cutting that the material area formed with first laser cutting subassembly cuts the second line of cutting that the material area formed reliably links up.

S207: and continuously moving the material belt along the preset path.

In this embodiment of the application, the moving the tape along the preset path (i.e., step S207) may include: and after the laser cutting of the tab is finished on the material belt, continuously moving the pole piece with the tab along the preset path, and conveying the pole piece to a winding assembly.

Specifically, the tab can be subjected to laser cutting at the first cutting position and the second cutting position respectively, and after the laser cutting is finally completed, the tab can be rolled through the rolling assembly to form the pole piece of the tab.

In the embodiment of the present application, the tab may be rectangular as shown in fig. 3, or may also be trapezoidal (as shown in fig. 6), square, or polygonal with a chamfer, etc.

The tab may be formed by only two laser cutting operations, or may be formed by more laser cutting operations. For example, in some embodiments, step S207 may further include: and continuously moving the material belt to a third cutting position along the preset path, and performing laser cutting on the material belt by using a third laser cutting assembly to form a third cutting line connected with the second cutting line on the material belt, wherein the third cutting line forms a third height area of the tab. That is, the tab cutting of the embodiment of the present application is not limited to only two laser cutting.

In this application embodiment, can set up two laser cutting subassemblies at a cross cutting station, wherein, one is responsible for cutting utmost point ear first half, and one is responsible for cutting utmost point ear the latter half, and the combination is used to reduce the power requirement to every equipment.
