[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-7 , the utility model provides a technical solution:

[0027] A circuit board cutting device includes an operating table 1, a motor 2 mounted on the operating table 1, a blade head 3 mounted on the motor 2, a blade 4 mounted on the blade head 3, a blade cover 5 positioned above the blade 4, a cutting hole 6 defined in the operating table 1 corresponding to the blade 4, a positioning device positioned on the other side of the cutting hole 6, and a slidable material container 10 positioned between the positioning device and the blade 4 on the operating table 1. The motor 2 drives the blade head 3 to rotate, which in turn drives the blade 4 to cut a plate held in the material container 10. The positioning device allows for rapid positioning and can adjust the desired cutting size.

[0028] Furthermore, the blade head 3 includes a blade mounting cover 11, a blade mounting post 12, and a connector 13. The connector 13 is mounted on the motor 2. The blade mounting post 12 corresponding to the blade 4 is coaxially welded to the connector 13. A blade mounting cover 11 is provided on the side of the blade mounting post 12 facing away from the connector 13. The blade mounting cover 11 and the connector 13 are provided with multiple groups of first threaded holes 14 corresponding to the fixing holes on the blade 4. The blade 4 is sleeved on the blade mounting post 12. Bolts pass through the blade mounting cover 11, the blade 4, and the connector 13 in sequence to fix the blade 4 to the blade head 3. The blade 4 should be replaced in a timely manner after it is worn significantly. Unscrew the bolts on the blade head 3, remove the blade mounting cover 11, and then the blade 4 can be removed from the blade mounting post 12 for replacement.

[0029] Furthermore, the positioning device includes two sets of positioning blocks 7 and positioning rods 9. Both sets of positioning blocks 7 are welded to the operating table 1. Both sets of positioning blocks 7 are provided with multiple sets of positioning holes 8. A positioning rod 9 is installed between the two sets of positioning blocks 7. The positioning rod 9 passes through the positioning holes 8 on the two sets of positioning blocks 7. By providing multiple sets of positioning holes 8 at different distances on the positioning blocks 7 as required, the distance between the positioning rod 9 and the blade 4 can be quickly adjusted.

[0030] Furthermore, the container 10 includes a box body 15 and a cover plate 16. Multiple sets of second threaded holes 17 are formed in the box body 15 and the cover plate 16. The cover plate 16 is fixed to the box body 15 by bolts. The end of the container 10 near the blade 4 is open, and the end of the container 10 away from the blade 4 abuts the positioning rod 9. The box body 15 is closely attached to the work surface 1 and can slide on the work surface 1. The operator loads the plate to be cut into the container 10 and, with the motor 2 turned on, slides the container 10 to quickly cut the plate.

[0031] Furthermore, a connecting rod 18 is welded on the operating table 1 corresponding to the knife cover 5, and the other end of the connecting rod 18 is welded to the knife cover 5, and the knife cover 5 is fixedly connected to the operating table 1 through the connecting rod 18. The knife cover 5 is used to prevent debris and sparks from flying during cutting.

[0032] Working principle: When the device is needed to cut the circuit board, adjust the distance between the positioning rod 9 and the blade 4, select a suitable container 10, load the board into the container 10, start the motor 2 to make the blade 4 rotate at high speed, hold the container 10 so that one end of the opening of the container 10 faces the blade 4, and the other end is against the positioning rod 9 and slides on the operating table 1 to complete the cutting. When cutting different lengths, adjust the distance between the positioning rod 9 and the blade 4. Multiple groups of positioning holes 8 can be set on the positioning block 7 according to commonly used length sizes, and corresponding containers 10 can be made. When in use, adjust the positioning rod 9 to pass through different positioning holes 8 to quickly adjust the required cutting size.
