[0040] Reference Figures 1-5 As shown, according to one embodiment of this application, a tab cutting device 1 is provided. The tab cutting device 1 includes a first blade group 11 and a second blade group 12. The first blade group 11 has a first blade edge; the second blade group 12 has a second blade edge. In the working state, the first blade edge and the second blade edge are arranged adjacent to each other along a first direction, and the first blade edge and the second blade edge are configured to perform a cutting operation on the tab.

[0041] The tab cutting device 1 further includes a first adjusting block 13 and a connecting block 14. The first adjusting block 13 is disposed on one side of the first blade assembly 11 along the second direction; the connecting block 14 is disposed on one side of the first blade assembly 11 along the first direction; the first adjusting block 13 and the connecting block 14 are connected to a first mating surface 101, the first mating surface 101 being inclined at a first predetermined acute angle relative to the first direction; the connecting block 14 is connected to the first blade assembly 11 on a second mating surface 102, the second mating surface 102 being inclined at a second predetermined acute angle relative to the first direction.

[0042] The first adjustment block 13 can move along the first direction and drive the adapter block 14 to move along the second direction through the first mating surface 101. The adapter block 14 drives the first blade assembly 11 to move along the first direction through the second mating surface 102, so as to adjust the distance between the first blade and the second blade along the first direction.

[0043] The tab cutting device provided in this application embodiment is used to cut the tabs of stacked electrode sheets during the battery manufacturing process, so that the length of the tabs meets the requirements. The structure of the tab cutting device 1 mainly includes a first blade group 11, a second blade group 12, a first adjusting block 13, an adapter block 14, and related connecting components.

[0044] The first blade assembly 11 has a first blade, and the second blade assembly 12 has a second blade. In operation, the first and second blades are arranged adjacent to each other along a first direction, cooperating to complete the cutting of the electrode tabs. To adjust the distance between the first and second blades to accommodate cutting electrode tabs of different sizes, the electrode tab cutting device 1 of this embodiment includes a first adjustment block 13 and a transition block 14. The first adjustment block 13 is located on one side of the first blade assembly 11 along the second direction, and the transition block 14 is located on one side of the first blade assembly 11 along the first direction. (Refer to...) Figure 1 , Figure 3 , Figure 4 As shown, the first direction is direction a, and the second direction is direction b.

[0045] The first adjusting block 13 and the adapter block 14 are connected by a first mating surface 101, which is inclined at a first predetermined acute angle relative to the first direction. Specifically, the first adjusting block 13 has a first sub-matting surface, and the adapter block 14 has a second sub-matting surface. The first and second sub-matting surfaces have the same inclination direction and angle, and they abut against each other to form the first mating surface 101. The adapter block 14 and the first blade assembly 11 are connected by a second mating surface 102, which is inclined at a second predetermined acute angle relative to the first direction. Specifically, the adapter block 14 has a third sub-matting surface, and the first blade assembly 11 has a fourth sub-matting surface. The third and fourth sub-matting surfaces have the same inclination direction and angle, and they abut against each other to form the second mating surface 102. This design allows the first adjusting block 13 to move along the first direction, which in turn drives the adapter block 14 to move along the second direction via the first mating surface 101. The adapter block 14 then drives the first blade assembly 11 to move along the first direction via the second mating surface 102, thereby adjusting the distance between the first and second blades to accommodate the cutting requirements of different sizes of tabs.

[0046] Specifically, if the adapter block 14 drives the first blade assembly 11 to move along the first direction and moves the first blade away from the second blade, the distance between the first blade and the second blade increases; if the adapter block 14 drives the first blade assembly 11 to move along the first direction and moves the first blade closer to the second blade, the distance between the first blade and the second blade decreases. Therefore, in the tab cutting device 1 provided in this application embodiment, through the cooperation of the first adjusting block 13 and the adapter block 14 with the first blade assembly 11, the distance between the first blade and the second blade can be adjusted, thereby improving the adaptability of the tab cutting device 1 to cutting tabs of different sizes.

[0047] Reference Figures 1-3 As shown, in one embodiment, the first blade assembly 11 includes a first blade 111 and a mating block 112, with the first cutting edge formed on the first blade 111; one side of the mating block 112 abuts against the first blade 111, and the other side of the mating block 112 is mated to the adapter block 14 on the second mating surface 102. Furthermore, the second blade assembly 12 includes a second blade 121, with a second cutting edge formed on the second blade 121.

[0048] In this specific example, the first blade assembly 11 includes a first blade 111 and a mating block 112. The first blade 111 is used to cooperate with the second blade 121 to jointly complete the cutting operation of the electrode tab. The mating block 112 is used to connect with the adapter block 14 and transmit the driving force of the adapter block 14. Specifically, the adapter block 14 has a third sub-mating surface, and the mating block 112 has a fourth sub-mating surface. The third and fourth sub-mating surfaces have the same tilt direction and tilt angle. The third and fourth sub-mating surfaces abut against each other and form a second mating surface 102.

[0049] Reference Figure 1 As shown, in one embodiment, the tab cutting device further includes a drive mechanism connected to the second blade group 12. The drive mechanism is capable of driving the second blade group 12 to move along a third direction, so that the second blade group 12 moves closer to or further away from the first blade group 11 along the third direction.

[0050] In this specific example, when the tab needs to be cut, the drive mechanism drives the second blade group 12 to move along a third direction towards the first blade group 11, so that the first cutting edge of the first blade 111 and the second cutting edge of the second blade 121 cooperate to cut the tab. After the cutting operation is completed, the drive mechanism drives the second blade group 12 to move along a third direction away from the first blade group 11, so as to facilitate the subsequent unloading of the cut tab.

[0051] Reference Figure 1As shown, in one embodiment, the second blade assembly 12 includes a second blade 121, a pressing member 122, and an air blowing member 123, with the second cutting edge formed on the second blade 121;

[0052] The pressing element 122 and the blowing element 123 are respectively disposed on both sides of the second cutter 121 along the first direction; the pressing element 122 is configured to press the tabs together during the cutting operation, and the blowing element 123 is configured to remove waste generated during the cutting operation.

[0053] In this specific example, the second blade assembly 12 includes a second blade 121, a clamping element 122, and an air blowing element 123. The second blade 121 cooperates with the first blade 111 to jointly complete the cutting operation of the electrode tabs. The clamping element 122 is located on one side of the second blade 121 along a first direction and is used to press the electrode tabs together during the cutting operation to prevent them from moving or deforming. The air blowing element 123 is located on the other side of the second blade 121 and is used to remove waste material generated during the cutting operation, keeping the working area clean.

[0054] Reference Figure 4 As shown, in one embodiment, the first predetermined acute angle is 30° to 60°. For example, the first predetermined acute angle is 45°; the specific angle value of the first predetermined acute angle can be flexibly set according to actual operational needs.

[0055] Reference Figure 4 As shown, in one embodiment, the second predetermined acute angle is 85° to 88°. For example, the second predetermined acute angle is 88°; the specific angle value of the second predetermined acute angle can be flexibly set according to actual operational needs.

[0056] Reference Figure 2 As shown, in one embodiment, the tab cutting device further includes a first threaded fastener 15, which is threadedly connected to the first adjusting block 13, and the first threaded fastener 15 is configured to drive the first adjusting block 13 to move along a first direction.

[0057] In this specific example, the first threaded fastener 15 is used to drive the first adjusting block 13 to move along the first direction, so that the position of the first tool group 11 can be precisely adjusted. The distance the first tool group 11 moves can be quantitatively controlled by the number of rotations of the first threaded fastener 15. The first threaded fastener 15 can be, for example, a screw.

[0058] In a specific example, refer to Figures 3-5As shown, the second cutting tool 121 is positioned above the first cutting tool 111 along the first direction. The mating block 112 and the adapter block 14 are sequentially positioned above the first cutting tool 111 along the first direction. The first adjusting block 13 is positioned to the left of the adapter block 14 along the second direction. When the first threaded fastener 15 is tightened to move the first adjusting block 13 upward along the first direction, the first adjusting block 13 pushes the adapter block 14 to move to the right along the second direction. The adapter block 14 then pushes the mating block 112 and the first cutting tool 111 downward along the first direction to increase the distance between the second cutting tool 121 and the first cutting tool 111, that is, to increase the distance between the first cutting edge and the second cutting edge.

[0059] Reference Figures 2-5 As shown, in one embodiment, the tab cutting device further includes a second adjusting block 16, which is disposed on the other side of the first blade assembly 11 along the second direction; the second adjusting block 16 is connected to the adapter block 14 in a third mating surface 103, the third mating surface 103 is inclined at a third predetermined acute angle relative to the first direction, and the inclination direction of the third mating surface 103 is opposite to the inclination direction of the first mating surface 101, and the second adjusting block 16 can move along the first direction.

[0060] In this specific example, the second adjusting block 16 can achieve the opposite driving effect to the first adjusting block 13; that is, if the first adjusting block 13 can increase the distance between the first blade and the second blade, the second adjusting block 16 can decrease the distance between the first blade and the second blade, thereby further improving the adaptability of the tab cutting device 1 to cutting tabs of different sizes.

[0061] Reference Figure 4 As shown, in one embodiment, the third predetermined acute angle is 30° to 60°. For example, the third predetermined acute angle is 45°; the specific angle value of the third predetermined acute angle can be flexibly set according to actual operational needs.

[0062] Reference Figure 2 As shown, in one embodiment, the tab cutting device further includes a second threaded fastener 17, which is threadedly connected to the second adjusting block 16, and the second threaded fastener 17 is configured to drive the second adjusting block 16 to move along a first direction.

[0063] In this specific example, the second threaded fastener 17 is used to drive the second adjusting block 16 to move along the first direction, so that the position of the first tool group 11 can be precisely adjusted. The distance the first tool group 11 moves can be quantitatively controlled by the number of rotations of the second threaded fastener 17. The second threaded fastener 17 can be, for example, a screw.

[0064] In a specific example, refer to Figures 3-5 As shown, the second cutting tool 121 is positioned above the first cutting tool 111 along the first direction. The mating block 112 and the adapter block 14 are sequentially positioned above the first cutting tool 111 along the first direction. The second adjusting block 16 is positioned to the right of the adapter block 14 along the second direction. When the second threaded fastener 17 is tightened to move the second adjusting block 16 upwards along the first direction, the second adjusting block 16 pushes the adapter block 14 to move to the left along the second direction. This creates a gap between the adapter block 14 and the mating block 112, allowing the mating block 112 and the first cutting tool 111 to move upwards along the first direction. This allows the positions of the mating block 112 and the first cutting tool 111 to be adjusted upwards along the first direction, thereby reducing the distance between the second cutting tool 121 and the first cutting tool 111, which in turn reduces the distance between the first cutting edge and the second cutting edge.

[0065] To ensure smooth operation, when it is necessary to tighten one of the first threaded fastener 15 and the second threaded fastener 17, the other can be loosened first, and then tightened again after adjustment.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application.
