Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-4 A finishing die-cutting device for polyimide film comprises a workbench 1, a liftable die-cutting table 2 is arranged inside the workbench 1, a U-shaped support frame 3 is fixed at one end of the top of the workbench 1, cylinders 4 are fixed at both ends of the U-shaped support frame 3, a die-cutting mounting plate 5 for connecting a die-cutting piece is fixed at the output end of the cylinder 4, and a lifting mechanism for lifting the die-cutting table 2 is arranged at the bottom of the workbench 1;

[0021] Both ends of the top of the die-cutting table 2 are provided with guide components, and the bottom of the die-cutting table 2 is provided with a rotating mechanism for rotating the guide components;

[0022] The jacking mechanism includes a U-shaped plate 6, which is fixed to the bottom of the workbench 1. A driving motor 7 is bolted to one end of the U-shaped plate 6. A first transverse threaded rod 8 is fixed to the output end of the driving motor 7. A second transverse threaded rod 9 is fixed to the end of the first transverse threaded rod 8 away from the driving motor 7. The thread rotation directions of the first transverse threaded rod 8 and the second transverse threaded rod 9 are opposite. The outer sides of the first transverse threaded rod 8 and the second transverse threaded rod 9 are both threadedly connected with a transverse moving block 11. A transverse light rod 10 is fixed inside the U-shaped plate 6. The transverse light rod 10 passes through the interior of the transverse moving block 11 and is slidably connected to the transverse moving block 11. Through the setting of the transverse light rod 10, the transverse moving block 11 can slide on the outer side of the transverse light rod 10, thereby guiding the sliding trajectory of the transverse moving block 11 on the outer side of the transverse light rod 10. The top of the transverse moving block 11 is rotatably connected to an oblique support column 12, and the top of the oblique support column 12 is rotatably connected to a transverse connecting plate 13. The top of the transverse connecting plate 13 is fixedly connected to the die-cutting table 2.

[0023] A partition is rotatably connected to the connection between the first transverse threaded rod 8 and the second transverse threaded rod 9 through a bearing, and the bottom of the partition is fixedly connected to the U-shaped plate 6. The setting of the partition makes the connection between the first transverse threaded rod 8 and the second transverse threaded rod 9 more stable, so as to facilitate the synchronous rotation of the first transverse threaded rod 8 and the second transverse threaded rod 9;

[0024] The operation of the driving motor 7 enables the first transverse threaded rod 8 and the second transverse threaded rod 9 to rotate. The rotation of the first transverse threaded rod 8 and the second transverse threaded rod 9 enables the two transverse moving blocks 11 to slide on the outside of the transverse light rod 10, and the moving directions of the two transverse moving blocks 11 are opposite. The movement of the two transverse moving blocks 11 enables the transverse connecting plate 13 to be vertically lifted and lowered through the oblique support column 12. The lifting and lowering of the transverse connecting plate 13 enables the die-cutting table 2 to be lifted and lowered, thereby enabling the film to be die-cut on the top of the workbench 1 to be lifted and lowered;

[0025] The guide assembly includes a longitudinal pressing roller 15, which is located on the top of the die-cutting table 2. Vertical rotating columns 14 are fixed on both sides of the longitudinal pressing roller 15. A longitudinal rotating shaft 20 is fixed inside the vertical rotating column 14. The longitudinal rotating shaft 20 passes through the interior of the die-cutting table 2 and is rotatably connected to the die-cutting table 2 through a bearing.

[0026] The rotating mechanism includes an arc-shaped fixed block 17, which is fixed to the bottom of the die-cutting table 2. A double-output shaft motor 16 is fixed inside the arc-shaped fixed block 17. A rectangular moving block 18 is fixed to the two output ends of the double-output shaft motor 16. One end of the rectangular moving block 18 away from the double-output shaft motor 16 is rotatably connected to an oblique rotating column 19 through a pin shaft. One end of the oblique rotating column 19 is rotatably connected to the bottom of the vertical rotating column 14 through a pin shaft.

[0027] After the die-cutting table 2 is lifted, the operation of the double-output shaft motor 16 enables the rectangular moving block 18 to move. The movement of the rectangular moving block 18 passes through the oblique rotating column 19, so that the vertical rotating column 14 can rotate with the longitudinal rotating axis 20 as the center, and then the longitudinal pressing roller 15 can press down the film so that the film can better fit the surface of the die-cutting table 2, so as to facilitate the die-cutting of the film;

[0028] Working principle: The operation of the driving motor 7 enables the first transverse threaded rod 8 and the second transverse threaded rod 9 to rotate. The rotation of the first transverse threaded rod 8 and the second transverse threaded rod 9 enables the two transverse moving blocks 11 to slide on the outside of the transverse light rod 10, and the moving directions of the two transverse moving blocks 11 are opposite. The movement of the two transverse moving blocks 11 enables the transverse connecting plate 13 to be vertically lifted and lowered through the oblique support column 12. The lifting and lowering of the transverse connecting plate 13 enables the die-cutting table 2 to be lifted and lowered, thereby enabling the film to be die-cut on the top of the workbench 1 to be lifted and lowered;

[0029] After the die-cutting table 2 is lifted, the operation of the double-output shaft motor 16 enables the rectangular moving block 18 to move. The movement of the rectangular moving block 18 passes through the oblique rotating column 19, so that the vertical rotating column 14 can rotate with the longitudinal rotating axis 20 as the center, and then the longitudinal pressing roller 15 can press down the film so that the film can better fit the surface of the die-cutting table 2, so as to facilitate the die-cutting of the film;

[0030] The die-cutting piece is mounted to the bottom of the die-cutting mounting plate 5. The operation of the cylinder 4 enables the die-cutting mounting plate 5 to be lifted vertically, so that the die-cutting piece can be lifted and lowered to facilitate the cutting of the film.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
