[0024] In the cutting device of this embodiment, the base 10 is configured to provide installation and operating conditions for cutting the electrode piece 20. Specifically, the through hole 101 formed on the base 10 enables the electrode piece 20 to pass through, and a first driver 30 is arranged on the base 10. A first cutter 40 is arranged at the driving end of the first driver 30, and an avoidance groove 410 is formed on the side of the first cutter 40 away from the first driver 30. When the first driver 30 drives the first cutter 40 to move along the first direction, the electrode piece 20 passing through the base 10 through the through hole 101 can be cut. During the above-mentioned cutting process, the pole ear glue 210 is located in the avoidance groove 410. Therefore, the first cutter 40 will not cut the pole ear glue 210 when cutting the pole piece 20 located in the through hole 101, thereby protecting the pole ear glue 210 of the pole piece 20 from damage, thereby ensuring the safety performance of the pole piece 20 after the battery cell is filled with liquid.

[0025] The first driver 30 may be implemented by a cylinder, which is not specifically limited here.

[0026] See attached Figure 3 The size of the avoidance groove 410 of the cutting device of this embodiment can be adaptively adjusted according to the size of the tab glue 210 to achieve the purpose of avoiding the tab glue 210, and no specific limitation is made here. In actual application, the side of the pole piece 20 close to the tab glue 210 is flush with the side of the first cutter 40 close to the avoidance groove 410.

[0027] Attached Figure 4 A schematic diagram of the pole ear 230 and the pole ear glue 210 arranged on the pole piece 20 is given in FIG.

[0028] When using a cutting device to cut the electrode piece 20 , the position of the electrode piece 20 on the base 10 is adjusted according to actual needs, thereby adjusting the cutting position 220 to meet actual needs. Even if the cutting position 220 of this embodiment is within the range of the electrode ear glue 210 , it will not affect the electrode ear glue 210 .

[0029] As a preferred solution of this embodiment, see Figures 1 to 3 A second cutter 50 is also provided on the base 10. The second cutter 50 is arranged opposite to the first cutter 40. A mounting groove 401 is formed on the side of the first cutter 40 close to the second cutter 50. The second cutter 50 can be located in the mounting groove 401 and match the first cutter 40 to cut the pole piece 20; wherein the avoidance groove 410 is located in the mounting groove 401.

[0030] In this embodiment, the second cutter 50 is used in conjunction with the first cutter 40. When the first driver 30 drives the first cutter 40 to reciprocate along the first direction to cut the pole piece 20, the cutting efficiency can be improved, thereby improving the working efficiency of the cutting device.

[0031] The setting of the mounting groove 401 can enhance the stability of the working cooperation between the second cutter 50 and the first cutter 40. When the first cutter 40 moves along the first direction, the two sides of the second cutter 50 slide and abut against the opposite ends of the mounting groove 401, thereby ensuring the stability of the two during the cutting operation and the smoothness of the movement of the first cutter 40.

[0032] The blades of the first cutter 40 and the second cutter 50 are supported by tungsten steel. The length of the first cutter 40 is adjusted according to the width of the electrode piece 20 to be cut, and can generally be 130 mm, 150 mm or 180 mm.

[0033] As a preferred solution of this embodiment, see Figure 1 The cutting device further includes: a substrate 60, a base 10 disposed on the substrate 60, and slidably connected to the substrate 60 along a second direction; wherein the second direction is perpendicular to the first direction.

[0040] The micrometer 70 can accurately know the sliding distance of the base 10 on the substrate 60 along the second direction, so that the staff can adjust the position of the first cutter 40 in the second direction according to the difference between the different types of pole ear glue 210 and the pole piece 20, so as to accurately control the position of the first cutter 40 and improve the cutting efficiency. The adjustment range of the micrometer 70 is 0 mm to 5.00 mm.

[0041] As a preferred solution of this embodiment, see Figure 1 and Figure 2The cutting device further includes: a threaded knob 71, which is disposed on the substrate 60. A threaded hole (not shown in the figure) is formed on the base 10, and the threaded knob 71 is threadedly connected to the threaded hole.

[0042] Among them, the setting of the threaded knob 71 is convenient to operate. When the threaded knob 71 is rotated, the base 10 can slide on the substrate 60, thereby improving the overall controllability of the cutting device.

[0044] The pole piece guide rail 80 is used to transfer the pole piece 20 to the through hole 101 so that the pole piece 20 passes through the base 10. In the actual production process, the pole piece guide rail 80 and the base 10 cooperate with each other to continuously cut the pole piece 20, realize assembly line work, and thus improve work efficiency.

[0045] As a preferred solution of this embodiment, see Figure 1 and Figure 2 The cutting device further includes: a mounting platform 90 , on which the base 10 and the pole piece guide rail 80 are both arranged.

[0046] The setting of the mounting platform 90 provides a stable mounting environment for the base 10 and the pole piece guide rail 80 , further improving the integration of the cutting device.
