[0003] The existing technology patent (patent number: 202223123624.1, patent name: A universal cutting die for processing flexible circuit boards) is equipped with a cutting die, a cutting knife, a nut and a screw. The cutting die and the cutting knife can be replaced according to different cutting requirements, thereby meeting the needs of cutting flexible circuit boards into different shapes.

[0004] The defects in the above patent are as follows: when the above device replaces the cutting die, the staff needs to screw multiple nuts and screws multiple times, and when replacing the cutting knife, the movable plate needs to be released, and the movable plate needs to be fixed after replacement, which is time-consuming and labor-intensive while reducing the cutting of the flexible circuit board. At the same time, the above device places the flexible circuit board under the second fixed plate for cutting, which results in the staff needing to remove the flexible circuit board and the cut part from under the second fixed plate after the cutting is completed, which results in the cut part being located inside the second fixed plate, thereby increasing the difficulty for the staff to remove the flexible circuit board and the cut part. Therefore, a universal cutting die for FPC flexible circuit boards is proposed to solve the above problems. Utility Model Content

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Reference Figure 1-6 , a universal cutting die for FPC flexible circuit boards, including a workbench 1, the top of the workbench 1 is fixedly connected to a vertical plate 2, the top of the vertical plate 2 is fixedly connected to a top plate 3, the top of the top plate 3 is fixedly connected to a hydraulic cylinder 4 (the hydraulic cylinder 4 drives the pushing plate 5 to move downward, and drives the movable plate 8 and the cutting knife to move downward to cut the flexible circuit board), the output end of the hydraulic cylinder 4 passes through the top plate 3, the bottom end of the hydraulic cylinder 4 is fixedly connected to the pushing plate 5, the top of the workbench 1 is provided with a through hole, a cylinder 12 is rotatably connected in the through hole, a disc 7 is fixedly connected to the surface of the cylinder 12, a plurality of handles 701 are fixedly connected to the top of the disc 7 (the disc 7 and the movable plate 8 are rotated by the handle 701, so that the cutting die body 11 and the cutting knife are replaced), a plurality of U-shaped placing plates 10 are fixedly connected to the top of the disc 7, a cutting die body 11 is arranged in the U-shaped placing plate 10, and the bottom end of the workbench 1 is fixedly connected to two symmetrically arranged column legs 101.

[0024] Furthermore, a slide groove 1002 is provided at both ends of the U-shaped placement plate 10, and a slide plate 1101 fixedly connected to the die cutter body 11 is slidably connected in the slide groove 1002. Different notches are provided at the tops of the multiple die cutter bodies 11 (to cut the flexible circuit board into different specifications). A movable groove 1001 is provided at both ends of the U-shaped placement plate 10, and a slot communicating with the multiple movable grooves 1001 is provided at the top of the U-shaped placement plate 10.

[0025] The top of the disc 7 is provided with a plurality of mounting grooves located below the U-shaped placement plate 10, in which a collection box 9 is slidably connected (the collection box 9 collects the cut parts), and one end of the collection box 9 is fixedly connected to a handle 901.

[0026] It should be noted that: a plurality of through grooves are opened on the surface of the cylinder 12, and a sliding column 1201 is fixedly connected to the through groove. A slider 803 is slidably connected to the surface of the sliding column 1201, and one end of the slider 803 is fixedly connected to the moving plate 8, and a spring ring is connected between the slider 803 and the through groove;

[0027] The movable plate 8 is aligned with the U-shaped placement plate 10. The bottom end of the movable plate 8 is fixedly connected to a cutting knife that fits the knife die body 11 (the cutting knife cuts the flexible circuit board). One end of the movable plate 8 is provided with multiple circular holes, and a movable tube 801 is slidably connected in the circular holes. The two ends of the movable tube 801 are fixedly connected to a contact plate 802 that is plugged into the slot.

[0028] It is worth noting that one end of the vertical plate 2 is fixedly connected to a receiving block 6, one end of the receiving block 6 is provided with a receiving groove, a return spring 601 is provided in the receiving groove, and one end of the return spring 601 is fixedly connected to a trapezoidal block 602 that is slidably connected to the receiving groove.

[0029] A further advantage of adopting the above method is that the above device does not require the installation and disassembly of the knife die body 11 and the cutting knife, which saves time and effort while improving the cutting of the flexible circuit board, and at the same time separates the flexible circuit board and the cut part, thereby facilitating the staff to remove the flexible circuit board and the cut part.

[0030] When the utility model is in use: when it is necessary to cut the flexible circuit board, the staff rotates the disc 7 through the handle 701, and rotates the required cutter die body 11 to the front of the staff, and then the staff places the flexible circuit board into the movable groove 1001, and then the staff rotates the disc 7 through the handle 701 (the staff can only rotate the disc 7 clockwise through the handle 701), and rotates the U-shaped placement plate 10 on which the flexible circuit board is placed to the bottom of the hydraulic cylinder 4 (when the staff feels resistance when rotating the disc 7, it means that the disc 7 has contacted the trapezoidal block 602, and at this time, the U-shaped placement plate 10 and one of the cutter die bodies 11 are already directly below the hydraulic cylinder 4). When the disc 7 rotates, it will drive the cylinder 12 and the movable plate 8 to rotate synchronously, so that the cutting knife that fits the notch on the U-shaped placement plate 10 on which the flexible circuit board is placed will move synchronously to the bottom of the hydraulic cylinder 4.

[0031] Then the staff starts the hydraulic cylinder 4, which drives the pushing plate 5 to move downward and pushes the movable plate 8 and the cutting knife located under the pushing plate 5 downward. When the movable plate 8 and the cutting knife move downward, the contact plate 802 will contact the flexible circuit board first and press and fix the flexible circuit board. At this time, the cutting knife moves downward and passes through the knife die body 11 and moves downward to the inside of the collection box 9, cutting the flexible circuit board while pushing the cut part into the collection box 9. Then the staff drives the hydraulic cylinder 4 to move upward, and then takes out the cut flexible circuit board. The staff can cut the flexible circuit board that needs to be cut into different shapes through the above method, and then the staff can take out the collection box 9 through the handle 901. The above device does not require the installation and disassembly of the knife die body 11 and the cutting knife, which saves time and effort while improving the cutting of the flexible circuit board, and at the same time separates the flexible circuit board and the cut part, thereby facilitating the staff to take out the flexible circuit board and the cut part.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
