[0028] The following is combined with the attachedFigure 1 ~Appendix Figure 3 A detailed description will be given to the embodiments of the present utility model.

[0029] An embodiment of the present utility model provides a PCB board cutting device. The PCB board cutting device includes: a support table 1, a cutting mechanism 2 located above the support table 1, a traveling mechanism 3 for driving the cutting mechanism 2 to move back and forth, and a first power source 4 for driving the cutting mechanism 2 to lift and lower. It should be understood that the traveling mechanism 3 can directly drive the cutting mechanism 2 to move back and forth, and the first power source 4 can indirectly drive the cutting mechanism 2 to lift and lower by driving the traveling mechanism 3 to lift and lower; alternatively, the first power source 4 can directly drive the cutting mechanism 2 to lift and lower, and the traveling mechanism 3 can indirectly drive the cutting mechanism 2 to move back and forth by driving the first power source 4 to move back and forth. Considering from the perspective of cost reduction, the first power source 4 is usually set as a cylinder. The cutting mechanism 2 includes: a mounting shaft 5 extending in the left-right direction, a second power source 6 for driving the mounting shaft 5 to rotate, and a plurality of cutting tools 7 arranged on the mounting shaft 5 in the left-right direction. It should be understood that the second power source 6 is usually set as a servo motor. The cutting tool 7 is provided with a first mounting hole penetrating through the left and right for a screw 8 to pass through. The left and right sides of the cutting tool 7 are limited by nuts provided on the screw 8, and each cutting tool 7 is connected by the screw 8. It should be understood that the screw 8 is parallel to the mounting shaft 5. The mounting shaft 5 is fixedly connected with a positioning member 9, and one of the cutting tools 7 is connected to the positioning member 9. It should be understood that one of the cutting tools 7 is connected to the positioning member 9, and each cutting tool 7 is connected by the screw 8 and the nut. Therefore, in fact, each cutting tool 7 is connected to the positioning member 9; and relative to the cutting tool 7 connected to the positioning member 9, the remaining cutting tools 7 can adjust their positions along the length direction of the mounting shaft 5.

[0030] The following elaborates on the specific implementation manner of the present utility model: One of the cutting tools 7 is connected to the positioning member 9 fixedly connected to the mounting shaft 5, and each cutting tool 7 is connected by the screw 8 and the nut. In this way, when the second power source 6 drives the mounting shaft 5 to rotate, each cutting tool 7 will also rotate synchronously, thereby cutting out multiple PCB boards at one time.
