The workbench 1 is equipped with a quick slotting mechanism 2, and the quick slotting mechanism 2 includes: a hydraulic rod 201, a lifting plate 202, an air pump 203, a conduit 204 and a ring-shaped slotting knife 205. The hydraulic rod 201 is fixed on the workbench 1, and the telescopic end of the hydraulic rod 201 is fixed to the lifting plate 202. The lower side of the lifting plate 202 is fixed with a ring-shaped slotting knife 205, and the bottom end of the ring-shaped slotting knife 205 is provided with a cutting edge. The lifting plate 202 is fixed with an air pump 203, and the air pump 203 is equipped with a conduit 204 inserted into the ring-shaped slotting knife 205. A chip groove 101 is provided on the workbench 1 directly below the annular slotting knife 205, and a trash box 5 is provided on the ground below the chip groove 101. A support block 4 is provided in the chip groove 101. The size of the chip groove 101 is larger than the top surface size of the support block 4, so that the support block 4 can rotate in the chip groove 101. The top surface size of the support block 4 is larger than the cross-sectional size of the annular slotting knife 205, so that the support block 4 provides good support for the annular slotting knife 205 during cutting. The support block 4 is rotatably connected to the workbench 1 through the rotating shaft 401, and a flipping mechanism 6 for driving the rotating shaft 401 and the support block 4 to rotate is installed at the bottom of the workbench 1. A positioning frame 3 is fixed on the workbench 1 below the quick slotting mechanism 2, and the circuit board 7 is placed in the positioning frame 3.

[0025] The flipping mechanism 6 includes: a driving motor 601, a first gear 602 and a second gear 603. The driving motor 601 is fixed to the bottom of the workbench 1. The first gear 602 is installed on the output shaft of the driving motor 601. A second gear 603 meshing with the first gear 602 is installed on one side of the first gear 602. The second gear 603 is installed on the rotating shaft 401. When in use, the first gear 602 and the second gear 603 are driven to rotate by the driving motor 601, and the rotating shaft 401 and the support block 4 are driven to rotate by the second gear 603.

[0026] The driving motor 601 is a servo motor.

[0027] Working principle: When the slotting device for printed circuit boards is used, the circuit board 7 is placed in the positioning frame 3, and then the hydraulic rod 201 drives the lifting plate 202 and the annular slotting knife 205 to move downward, so that the annular slotting knife 205 directly opens a groove on the circuit board 7, and the cut-off part of the circuit board 7 enters the annular slotting knife 205. At this time, the support block 4 is located directly below the annular slotting knife 205 to provide support for its cutting. After the slotting is completed, the hydraulic rod 201 drives the lifting plate 202 and the annular slotting knife 205 to move downward. The knife 205 moves back to its position, and then the circuit board 7 is removed. The first gear 602 and the second gear 603 are driven to rotate by the driving motor 601, and the rotating shaft 401 and the support block 4 are driven to rotate by the second gear 603, so that the support block 4 is removed from the chip groove 101. Then, air is blown into the annular slotting knife 205 through the air pump 203 and the conduit 204, so that the waste cut from the circuit board 7 in the annular slotting knife 205 is blown out and passes through the chip groove 101 and falls into the trash box 5 to be collected.
