The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0039] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0040] In existing technologies, after the electrode sheet is wound, the dummy tabs extending from the electrode sheet need to be cut to a specified size before subsequent welding processes can be carried out. In related technologies, the cutting tools need to be replaced as a whole after prolonged use and wear. This not only requires long-term downtime for installation, reducing processing efficiency, but also wastes resources.

[0041] Based on the above problems, a cutting mechanism is proposed according to an embodiment of this utility model. This mechanism can be used for cutting dummy electrode tabs, but is not limited to cutting dummy electrode tabs. It can be used to cut electrode sheets or other components such as electrode tabs, as needed. This not only improves work efficiency but also saves on operating costs. (Refer to...) Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the first cutting mechanism according to an embodiment of the present invention. Figure 2 for Figure 1 The explosive intent of the first cutting component in the middle. Figure 3 for Figure 1 The schematic diagram of the structure of the second cutting component in this embodiment shows that the cutting process includes: mounting component 100, first cutting component 200, second cutting component 300, and driving device 400.

[0042] The first cutting assembly 200 includes a first cutting tool 210, which has a plurality of first cutting edges 211 (e.g., ...). Figure 2 As shown), the first cutter 210 is configured as a triangle, square, or pentagon, etc., with a first cutting edge 211 on each side. The first cutter 210 is movably connected to the mounting member 100 by means of rotational connection or detachable connection, and the first cutter head 230 can be directly connected to the mounting member 100 or indirectly connected to the mounting member 100 through other components (such as the first cutter head 230 in the embodiment below). The second cutting assembly 300 includes a second cutter 310 (e.g., Figure 3The first cutter 210 and the second cutter 310 are distributed along a first direction, for example, a vertical direction, i.e. the first cutters 210 and the first cutters 210 are distributed along the vertical direction, the second cutter 310 is directly connected to or indirectly connected to the mounting member 100 through other structures (for example, the second cutter rest 330 and the connecting member 340 of the second embodiment below), and the second cutter 310 has a second cutting edge 311, each first cutting edge 211 can be adjusted to a position facing the second cutter 310, for example, taking the first cutter 210 connected to the first cutter rest 230 as an example, the first cutting assembly 200 further comprises a first locking member 220, for example, a screw or a clamping device, etc., for locking the angle of the first cutter 210, so that the orientation of the first cutting edge 211 is locked, when the first cutter 210 is rotationally connected to the first cutter rest 230, and the first cutting edge 211 needs to be adjusted during the working process, first, the first locking member 220 is used to unlock the first cutter 210, and the first cutter 210 is rotated to adjust another first cutting edge 211 to a position facing the second cutter 310, and then the first locking member 220 is used to fix the first cutter 210 to the first cutter rest 230. When the first cutter 210 is detachably connected to the first cutter rest 230, when switching the first cutting edge 211, the first locking member 220 is used to unlock the first cutter 210, and the first cutter 210 is detached and replaced by another first cutter 210 in a different position to be installed on the first cutter rest 230, so that another first cutting edge 211 faces the second cutter 310.

[0043] The driving device 400 is used to relatively move the first cutter 210 and the second cutter 310 in the first direction, so that the first cutting edge 211 and the second cutting edge 311 facing each other jointly cut the pseudo tab. For example, the driving device 400 comprises a first driving member connected to the first cutter 210 for driving the first cutter 210 to reciprocate along the first direction, or the driving device 400 comprises a second driving member connected to the second cutter 310 for driving the second cutter 310 to reciprocate along the first direction, or the driving device 400 comprises a first driving member connected to the first cutter 210 for driving the first cutter 210 to reciprocate along the first direction and a second driving member connected to the second cutter 310 for driving the second cutter 310 to reciprocate along the first direction, and the first driving member and the second driving member can be, for example, a pneumatic cylinder, a hydraulic cylinder or a motor, etc.

[0044] As can be seen from the above, in the embodiment, the first cutter 210 has a plurality of first cutting edges 211, and the first cutter 210 is movably connected to the mounting member 100, so that, during the cutting process, when one of the first cutting edges 211 is worn, another first cutting edge 211 that is not worn can be adjusted to a position facing the second cutter 310, without replacing the first cutter 210, thereby avoiding long downtime for replacing the cutter, improving the efficiency of the battery cell processing, and saving the use cost.

[0045] With reference to Figure 3 On the basis of the above embodiment, the second cutter 310 includes a plurality of second cutting edges 311, and the second cutter 310 is movably connected to the mounting member 100, and each of the second cutting edges 311 can be adjusted to a position facing the first cutter 210, so that, when one of the second cutting edges 311 of the second cutter 310 is worn, another second cutting edge 311 can be switched without replacing the second cutter 310, thereby avoiding long downtime for replacing the cutter, improving the efficiency of the battery cell processing, and saving the use cost.

[0046] In some embodiments, the plurality of first cutting edges 211 includes a first cutting edge 211A and a first cutting edge 211B, and in the first direction, the projection length of the first cutting edge 211A is not equal to the projection length of the first cutting edge 211B, and in the plurality of second cutting edges 311, the projection length of at least one second cutting edge 311 is not less than the projection length of the first cutting edge 211A, and the projection length of at least one second cutting edge 311 is not less than the projection length of the first cutting edge 211B. Therefore, during the processing, different cutting edge (first cutting edge 211 and second cutting edge 311) combinations can be selected according to different battery cells, thereby improving the practicability of the cutting mechanism of the embodiment. Specifically, it can be understood that for a battery cell with a dummy tab, it usually includes two dummy tabs spaced apart along the width direction of the battery cell, and for battery cells of different sizes, the distance between the two dummy tabs is not the same, and in the first cutting edges 211 of the embodiment, at least two first cutting edges 211A and 211B of different sizes in the first direction are included, for example, the projection length of the first cutting edge 211A in the first direction is less than the projection length of the first cutting edge 211B in the first direction, when the distance between the two dummy tabs of the battery cell to be cut is small, the first cutting edge 211A with smaller projection length is selected, and when the distance between the two dummy tabs is long, the first cutting edge 211B with larger projection length is selected, so that the cutting mechanism of the embodiment can cut battery cells of different sizes, thereby improving the practicability of the cutting mechanism of the embodiment.

[0047] In order to further improve the practicability of the cutting mechanism of the embodiment, with reference to Figure 7 , Figure 7As shown in the structure schematic view of the second cutting mechanism of the utility model embodiment, in some embodiments, the cutting mechanism further comprises a second transverse moving device 600, for example, the second transverse moving device 600 comprises a motor, a pneumatic cylinder or a hydraulic cylinder, etc., the second transverse moving device 600 is connected to the mounting piece 100, and is used to drive the mounting piece 100 to move along a third direction, the third direction is perpendicular to the first direction and the second direction, the second direction is perpendicular to the first direction, and is perpendicular to the extension direction of the first blade 211.In the processing process, the arrangement direction of the false tab on the battery cell is the same as the third direction, so when the distance between the two false tabs on the battery cell is too large, and it is difficult to cut the two false tabs at one time, the mounting piece 100 can be moved along the second direction, and the first cutter 210 and the second cutter 310 can be driven to move along the third direction, so as to cut the two false tabs separately, so it can be understood that as long as the distance between the two false tabs is within the driving stroke range of the second transverse moving device, the cutting mechanism of the embodiment can be used to cut the two false tabs, thereby improving the practicability of the embodiment.

[0048] It can be understood that for different battery cells, the size of the false tab protruding from the tab required for welding is also different, based on this, in order to meet the requirement that the cutting mechanism can realize cutting of false tabs with different sizes, in some embodiments, the cutting mechanism further comprises a first transverse moving device 500 (as shown in the figure), for example, the first transverse moving device 500 comprises a motor, a pneumatic cylinder or a hydraulic cylinder, etc., the first transverse moving device 500 is connected to the mounting piece 100, and is used to drive the mounting piece 100 to move along a second direction, the second direction is perpendicular to the first direction, and is perpendicular to the extension direction of the first blade 211. Figure 7 Specifically, in the processing process of the battery cell, the cutting mechanism of the embodiment is arranged on one side of the battery cell conveying device in the second direction, and the false tab faces the cutting mechanism, so in the cutting process, the mounting piece 100 can be driven to move along the second direction by the first transverse moving device 500, and the first cutter 210 and the second cutter 310 can be driven to move along the second direction, so as to adjust the cutting position of the false tab in the second direction, thereby adjusting the size of the false tab after cutting, and further improving the practicability of the cutting mechanism of the embodiment. In some embodiments, the cutting mechanism simultaneously has the first transverse moving device 500 and the second transverse moving device 600 in the above-mentioned embodiments, the mounting piece 100 is connected to the first transverse moving device 500, the first transverse moving device 500 is connected to the second transverse moving device 600, so that the first cutter 210 and the second cutter 310 can simultaneously have the ability to move along the second direction and the third direction.

[0049] Referring to Figure 2 and Figure 3In some embodiments, in the second direction, the first cutter 210 has two first cutting surfaces 212 oppositely arranged, and the edge of each first cutting surface 212 is arranged as the first blade 211. The second cutter 310 has two second cutting surfaces 312 oppositely arranged, and the edge of the second cutting surface 312 is arranged as the second blade 311. The first cutter 210 and the second cutter 310 are staggered in the second direction. Therefore, in use, one first cutting surface 212 in the first cutter 210 and one second cutting surface 312 in the second cutter 310 can be used to cut the dummy tab. For example, in the second direction, the first cutter 210 has a first cutting surface 212A and a first cutting surface 212B oppositely arranged, and the second cutter 310 has a second cutting surface 312A and a second cutting surface 312B. In use, the first cutting surface 212A and the second cutting surface 312A can be used to cut the dummy tab. When the first blade 211 on the first cutting surface 212A is worn out, the installation posture of the first cutter 210 or the second cutter 310 can be adjusted, for example, the first cutter 210 is flipped to make the first cutting surface 212B cooperate with the second cutting surface 312A, without replacing the first cutter 210, thereby shortening the replacement time of the first blade 211 and improving the processing efficiency of the battery cell.

[0050] It should be noted that the cooperation of the first cutting surface 212A and the second cutting surface 312B described above includes but is not limited to that the first cutting surface 212 and the second cutting surface 312 are in contact when the first cutter 210 moves towards the second cutter 310. They can also have a small gap, for example, in the second direction, the gap between the first cutting surface 212A and the second cutting surface 312B is 0 to 0.5 mm, as long as the dummy tab can be cut.

[0051] Referring to Figures 1 to 3On the basis of the above-mentioned embodiments, the first cutting assembly 200 further comprises a first tool rest 230 connected to the mounting member 100, and the first cutting tool 210 is connected to the first tool rest 230 and partially protrudes from the first tool rest 230 towards the first cutting tool 210. The second cutting assembly 300 further comprises a second tool rest 330 connected to the mounting member 100, and the second cutting tool 310 is connected to the second tool rest 330 and partially protrudes from the second tool rest 330 towards the first cutting tool 210, and the second cutting tool 310 is capable of moving relative to the first cutting tool 210 along the second direction, so as to adjust the relative position of the first cutting tool 210 and the second cutting tool 310 in the second direction. Specifically, as mentioned above, in the second direction, the first cutting tool 210 has the first cutting surface 212A and the first cutting surface 212B arranged oppositely, and the second cutting tool 310 has the second cutting surface 312A and the second cutting surface 312B, and in use, the first cutting surface 212A and the second cutting surface 312A can be used to cut the dummy electrode ear, and when the first cutting edge 211 on the first cutting surface 212A is worn out, the first cutting tool 210 or the second cutting tool 310 is moved along the second direction, so that the first cutting surface 212B and the second cutting surface 312B are matched, without the need to disassemble the first cutting tool 210 or the second cutting tool 310 and then flip, so as to improve the switching efficiency of the cutting surface, and further improve the processing efficiency of the battery cell.

[0052] In addition, since the first cutting tool 210 and the second cutting tool 310 can move relative to each other in the second direction in the present embodiment, the positional relationship between the first cutting surface 212 and the second cutting surface 312 can be more accurately controlled, so as to prevent the cutting tool from colliding during the cutting process.

[0053] Referring to Figure 1 and Figure 5 , Figure 5 for Figure 2The structure diagram of the first cutter can know that during the machining process, the equipment will generate a certain vibration, which may cause a certain change in the relative position between the first cutter 210 and the second cutter 310. If the position between the first cutter 210 and the second cutter 310 in the second direction decreases, the first cutter 210 and the second cutter 310 will collide during cutting. For example, the first cutting surface 212A cooperates with the second cutting surface 312A to cut the dummy earring. Normally, the first cutting surface 212A is located outside the second cutting surface 312A and the second cutting surface 312B. If the first cutting surface 212A moves between the second cutting surface 312A and the second cutting surface 312B due to vibration and other factors, the first cutter 210 will directly collide with the second cutter 310 during work, which not only causes the cutting to fail, but also causes the first cutter 210 and the second cutter 310 to be damaged. Based on this, in some embodiments, the surface of the first cutter 210 between the two first cutting surfaces 212 is a first surface 214, and the first cutter 210 further has a first guide portion 215 (as shown in Figure 5 The end of the first guide portion 215 away from the first surface 214 is provided with two first guide surfaces 2151, and the two first surfaces 214 are oppositely arranged in the second direction. In the direction from the first guide portion 215 to the first surface 214, the distance between the two first guide surfaces 2151 gradually increases. Therefore, during the working process, once the first cutter 210 and the second cutter 310 are slightly offset, when the second cutter 310 moves towards the first cutter 210, the second cutter 310 can slide against the first guide surface 2151 to form a certain angle of deflection, so as to adjust the relative position of the first cutter 210 and the second cutter 310, thereby avoiding the second cutter 310 directly abutting on the first surface 214 and failing to normally cut, thereby improving the reliability of the cutting mechanism of the embodiment.

[0054] Similarly, in some embodiments, the surface of the second cutter 310 between the second cutting surfaces 312 is a second surface, and the second cutter 310 further has a second guide portion connected to the second surface and protruding from the second surface. The end of the second guide portion away from the second surface is provided with a second guide surface, thereby playing a certain guiding role on the first cutter 210.

[0055] Referring to Figure 3 and Figure 4 , Figure 4 for Figure 3In some embodiments, the second cutting assembly 300 further comprises a connecting member 340 connected to the mounting member 100, the second tool rest 330 has a first connecting portion 331 and a second supporting portion 332 connected to the first connecting portion 331 and protruding from the first connecting portion 331 towards the first tool 210, the second tool 310 is connected to the second supporting portion 332, the first connecting portion 331 is movable relative to the connecting member 340 in the second direction, the side of the first connecting portion 331 away from the mounting member 100 has a first connecting hole 3311, and a third locking member is arranged in the first connecting hole 3311 and movably connected to the connecting member 340 for fixing the second tool rest 330 to the connecting member 340. For example, the first connecting portion 331 is provided with a plurality of first connecting holes 3311 distributed in the second direction, the connecting member 340 is provided with a second connecting hole 341, and the second tool rest 330 is moved in the second direction according to requirements during installation, one of the first connecting holes 3311 is aligned with the second connecting hole 341, the third locking member is arranged in the first connecting hole 3311 and extends into the second connecting hole 341 to be connected to the connecting member 340, so as to lock the second tool rest 330 to the connecting member. Alternatively, in some embodiments, the first connecting hole 3311 has an extension in the second direction, i.e., the first connecting hole 3311 is arranged as a waist-shaped hole extending in the second direction, so as to realize the adjustment and locking of the second tool rest 330 in the second direction. The first connecting hole 3311 is arranged on the side of the first connecting portion 331 away from the mounting member 100, so as to facilitate the operation of the third locking member, thereby making the adjustment of the second tool rest 330 more simple and convenient.

[0056] With reference to Figure 3 and Figure 4 In some embodiments, the side of the connecting member 340 away from the mounting member 100 has a avoiding slot 342, the second tool 310 is connected to the side of the second supporting portion 332 facing the mounting member 100 and partially arranged in the avoiding slot 342, so as to reduce the size of the second supporting portion 332 in the first direction, thereby making the cutting mechanism more compact.
