13. The terminal strip shearing device according to claim 1, characterized in that: Also includes: a frame (9), on which the rotating shaft (63) of the cam member (6) is rotatably mounted; and A driving device is mounted on the frame (9) and is used to drive the cam member (6) to rotate.

14. The terminal strip cutting device according to claim 13, characterized in that: The driving device comprises: A servo motor (63) is mounted on the frame (9); A first pulley (64) coaxially connected to the rotating shaft (63) of the cam member (6); A second pulley (65) connected to the drive shaft of the servo motor (63); and A transmission belt (66) is connected between the first pulley (64) and the second pulley (65).

15. The terminal strip cutting device according to claim 6, characterized in that: Also includes: A waste material discharge channel (7) whose entrance is connected to the slot hole (201) on the first shearing die (2) so as to discharge the waste material cut from the terminal material strip (1) to the outside of the terminal material strip shearing device.

16. The terminal strip cutting device according to claim 6, characterized in that: The first shearing die (2) further comprises: A first connecting member (25), an upper end of which is connected to the first substrate (20); and a first roller (25a), rotatably connected to the lower end of the first connecting member (25), The first cam (61) has an outer peripheral surface (61a), and the first roller (25a) is in rolling cooperation with the outer peripheral surface (61a) of the first cam (61). When the first cam (61) rotates, the outer peripheral surface (61a) of the first cam (61) drives the first shearing die (2) to move in the vertical direction.

17. The terminal strip cutting device according to claim 6, characterized in that: The second shearing die (2) further comprises: A second connecting member (35), an upper end of which is connected to the second substrate (30); and a second roller (35a), rotatably connected to the lower end of the second connecting member (35), A cam groove (62a) is formed on the second cam (62), and the second roller (35a) is rollingly engaged with the cam groove (62a). When the second cam (62) rotates, the cam groove (62a) of the second cam (62) drives the second shearing die (3) to move in the vertical direction.

18. The terminal strip cutting device according to claim 6, characterized in that: Also includes: A pair of support plates (5) for supporting the bottom of both sides of the terminal strip (1). The pair of support plates (5) are capable of moving between an extended position supporting the terminal strip (1) and a retracted position not interfering with the movement of the first shearing die (2). When the terminal strip (1) is moved to a predetermined shearing position, the pair of support plates (5) are moved to a retracted position to allow the first shearing die (2) to move upward and support the bottom of the terminal strip (1).

19. The terminal strip shearing device according to claim 18, characterized in that: Also includes: A pair of cylinders (51) are mounted on the frame (9) of the terminal strip shearing device and are used to respectively drive the pair of support plates (5) to move between the extended position and the retracted position.

20. A terminal strip cutting system, characterized in that: include: The terminal strip shearing device according to any one of claims 1 to 19, arranged at a shearing station; A terminal material strip conveying channel (8) for guiding the terminal material strip (1) to move to the shearing station along a predetermined conveying direction; and A terminal material strip conveying device is used to drive the terminal material strip (1) to move along the terminal material strip conveying channel (8).
