[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] like Figure 1 As shown, the structure of the circuit board, the shielding cover bracket 5 is provided with connecting ribs 51, and the shielding cover shearing device in the embodiment of the utility model is to shear the connecting ribs 51, and the connecting ribs 51 on the shielding cover of the circuit board are sheared by the feeding mechanism 2, the pressing mechanism 3 and the shearing mechanism 4, thereby realizing the automation of shearing of the shielding cover of the circuit board and improving the shearing efficiency.

The feeding mechanism 2 includes a circuit board placing plate 21 and a placing plate driving mechanism. The circuit board placing plate 21 is used to place the circuit board to be sheared. The placing plate driving mechanism is used to drive the circuit board placing plate 21 to move, so as to facilitate feeding. The pressing mechanism 3 is arranged above the circuit board placing plate 21, so that after the feeding mechanism 2 completes the feeding, it can be pressed on the circuit board placing plate 21 to fix the circuit board. The shearing mechanism 4 includes a shearing clamp 41 and a shearing clamp 41 driving mechanism. The shearing clamp 41 is connected to the shearing clamp 41 driving mechanism. The shearing clamp 41 top removal mechanism can drive the shearing clamp 41 to move and open and close, so as to trim the shielding cover on the circuit board.

[0026] Through the above arrangement, the circuit board only needs to be placed on the circuit board placement plate 21 manually or by a robot, and the circuit board can be automatically fixed and cut, thereby realizing the automation of cutting the circuit board shielding cover.

[0027] Specifically, a circuit board card slot 211 is provided on the circuit board placement plate 21. The circuit board card slot 211 is hollowed out and can hold the circuit board. After the circuit board is placed in place, the shielding cover is facing downward, so that it is convenient for the shearing pliers 41 to cut it.
