[0035] Working principle: The utility model is a high-performance circuit board cutting device. When it is necessary to cut the circuit board, the number and position of the cutting blades 15 are first determined according to the needs. When removing the cutting blades 15, the locking screws 11 are first unscrewed to release the fixing of the cutting blades 15. Then, the vertical plate 12 is moved to the left. The vertical plate 12 drives the slider 10 to move in the inner cavity of the chute 9. The vertical plate 12 drives the cutting blades 15 until the slider 10 moves away from the chute 9 and the cutting blades 15 move through the slot 19. In this way, the cutting blades 15 are removed.

[0036] When the position of the cutting blade 15 needs to be moved, the locking screw 11 is first unscrewed to release the fixing of the cutting blade 15, and then the vertical plate 12 is moved. The vertical plate 12 drives the slider 10 to move in the inner cavity of the slide groove 9, and the vertical plate 12 drives the cutting blade 15 until the vertical plate 12 drives the slider 10 to move to a suitable position so that the slider 10 is located under the screw hole at the corresponding position, and then the locking screw 11 is tightened to fix the slider 10, thereby completing the position adjustment of the cutting blade 15;

[0037] In the above operation, by unscrewing the locking screw 11 and releasing the fixation of the slider 10, the position of the cutting blade 15 can be adjusted. The cutting blade 15 can also be removed from the horizontal bar 8, thereby facilitating the cutting operation of circuit boards of different sizes, thereby solving the problem that the existing cutting device cannot cut and process circuit boards of different sizes;

[0038] Then, the first motor 18 and the second motor 20 are started by an external power supply. When the first motor 18 is working, the connecting column 14 is driven to rotate through the square rod 17, and the connecting column 14 drives the cutting blade 15 to rotate. When the second motor 20 is working, it drives the conveyor belt 6 to transport the circuit board, and transports the circuit board on the surface of the conveyor belt 6 to the cutting blade 15. The circuit board is cut by the cutting blade 15. At the same time, the cutting groove 7 on the surface of the conveyor belt 6 ensures that the cutting blade 15 does not contact the conveyor belt 6 during the cutting process, so that the conveyor belt 6 is not easily damaged. The cut circuit board falls from the surface of the conveyor belt 6 into the receiving plate 27, and slides into the collecting trough 30 through the receiving plate 27, thereby realizing the function of automatically collecting and storing the cut circuit boards, thereby improving the working efficiency of the cutting device.

[0039] When the second motor 20 is working, the second rotating rod 25 rotates through the setting of the first groove wheel 22, the second groove wheel 23 and the belt 24. The second rotating rod 25 drives the eccentric wheel 26 to continuously hit the receiving plate 27, so that the circuit boards that fall to the top of the receiving plate 27 can fall into the collecting trough 30 faster, avoiding the circuit boards from piling up on the top of the receiving plate 27, making it convenient to collect the cut circuit boards.
