[0041] Referring to Figure 1 and Figure 2 It is shown that the slitting device related to the embodiments of the application has a first direction x, and the slitting device comprises a mounting member 100, a slitting assembly 200 and a driving assembly 300.

[0042] Specifically, the mounting piece 100 is arranged to extend along a first direction x; the slitting assembly 200 comprises two first slitting pieces 210 and a plurality of second slitting pieces 220, the two first slitting pieces 210 are respectively fixedly connected at two side edges of the mounting piece 100 along the first direction x, and the plurality of second slitting pieces 220 are arranged between the two first slitting pieces 210 and are fixedly connected on the mounting piece 100 along the first direction x; the driving assembly 300 comprises a first driving piece corresponding to each second slitting piece 220, each first driving piece is connected with a second slitting piece 220 and is used for driving the second slitting piece 220 to move relative to the mounting piece 100 along the first direction x.

[0043] It should be noted that the first direction x is Figure 1 the direction indicated by x.

[0044] In the slitting device of the present application, since the two first slitting pieces 210 are respectively fixedly connected at the two side edges of the mounting piece 100 along the first direction x, the edges of the diaphragm can be cut by the two first slitting pieces 210. In the production process of the diaphragm, the edges of the diaphragm are prone to wear and tear and the edges are not neat enough. Therefore, cutting the edges of the diaphragm by the first slitting pieces 210 can improve the quality of the diaphragm. In addition, since the plurality of second slitting pieces 220 are arranged between the plurality of first slitting pieces 210 and are fixedly connected on the mounting piece 100 along the first direction x, the diaphragm can be cut by the plurality of second slitting pieces 220. Further, since each first driving piece is connected with a second slitting piece 220 and is used for driving the second slitting piece 220 to move relative to the mounting piece 100 along the first direction x, the first driving piece can drive the second slitting piece 220 to move along the first direction x, so as to adjust the distance between any two adjacent second slitting pieces 220, thereby adjusting the slitting width of the diaphragm, so that the diaphragm can be slitted according to the preset width. The process does not need manual adjustment, which saves time and effort and improves the slitting efficiency of the diaphragm.

[0045] Referring to Figure 2 , the slitting assembly 200 further comprises a plurality of sliding pieces 230, the plurality of sliding pieces 230 are fixedly connected on the mounting piece 100 along the first direction x, each second slitting piece 220 is connected with a sliding piece 230, and each first driving piece is connected with a sliding piece 230 and is used for driving the sliding piece 230 to slide relative to the mounting piece 100 along the first direction x.
