Description

Technical Field

[0001] The utility model relates to a flexible circuit board processing technology, in particular to a cutting device for processing a flexible circuit board. Background Art

[0002] At present, in the field of flat panel displays such as liquid crystal and organic electroluminescent display devices, the binding between the display screen and the driver chip is gradually being phased out as the pitch of the lead-out line becomes increasingly smaller. Instead, TCP, COF and other connection methods are being adopted in which the driver chip is directly prepared on a flexible circuit board. During the processing of this type of flexible circuit board, a cutting device is required to change its width.

[0003] Existing cutting devices for processing flexible circuit boards require the flexible circuit board to be placed within the cutting area of ​​the machine during cutting. However, since the naturally placed flexible circuit board will curl to a certain extent, it is often completely fixed in the cutting area using tape or external structures to ensure its surface is flat and thus ensure accurate cutting. However, existing fixing methods are cumbersome to fix and release, lack automation, are complex to operate, and are not convenient to use. Therefore, we propose a cutting device for processing flexible circuit boards to solve the above problems. Utility Model Content

[0021] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. 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.

[0022] See also Figures 1-6As shown, a cutting device for processing flexible circuit boards includes a cutting machine body 1, a processing chamber 2 is provided in the cutting machine body 1, and a structure for cutting flexible circuit boards is installed in the processing chamber. The structure and device are existing mature technologies. A movable plate 3 is slidably connected to the processing chamber 2, and a protective plate is rotatably connected to the outer side of the processing chamber 2, which can be used to open and pull the movable plate 3 to slide outward when needed; a flattening component, which includes vertical plates 4 fixedly connected to the left and right sides of the top of the movable plate 3, and movable grooves 5 are respectively opened on the front and back sides of the vertical plates 4. The movable grooves 5 It is used to guide the rotating roller 12 so that it moves in the arranged direction. The front and rear sides of the two vertical plates 4 are fixedly connected with a through plate 6. The through plate 6 is used to facilitate the installation of the screw rod 7 and the motor 18. The screw rod 7 is rotatably connected between the two through plates 6 and is symmetrically distributed on the left and right. The rear ends of the screw rods 7 are fixedly connected with pulleys 8. The same belt 9 is tensioned between the outer sides of the two pulleys 8. The pulleys 8 and the belt 9 are used to facilitate the rotation of the two screw rods 7 by a motor 18. The outer sides of the screw rod 7 are respectively threaded with a moving frame 10. , the mobile frame 10 is slidably connected to the top of the mobile plate 3, and a movable groove 11 is opened on the mobile frame 10. The movable groove 11 is used to change the height of the roller 12 following the path of the mobile groove 5 when the roller 12 moves with the mobile frame 10, so as to avoid interference during the working process and release the freedom of the roller 12. The same roller 12 is movably connected between the two relatively movable grooves 5. The outer side of the roller 12 is fixedly connected to the flattening roller 13. The flattening roller 13 is used to roll and flatten the surface of the flexible circuit board when moving. The two mobile frames 10 are on the side away from each other. A triangular block 14 is fixedly connected to the bottom. The triangular block 14 is used to contact and push the pressure rod 17 downward when moving with the mobile frame 10, so that one end of the pressure rod 17 is pressed against the surface of the flexible circuit board. A through groove 15 is respectively provided at the bottom of the front and rear sides of one side of the vertical plate 4. A spring 16 is fixedly connected to the bottom of the through groove 15. The spring 16 is used to push the pressure rod 17 upward when the triangular block 14 is no longer in contact with one end of the pressure rod 17, thereby releasing the pressure on the flexible circuit board and facilitating material unloading. A pressure rod 17 is also slidably connected in the through groove 15, and the pressure rod 17 is fixedly connected to one end of the spring 16.

[0023] Furthermore, a motor 18 is fixedly connected to one side of one of the through plates 6, and the output end of the motor 18 is fixedly connected to one end of the adjacent screw rod 7. By driving the screw rod 7 to rotate by the motor 18, the flattening speed of the flexible circuit board can be greatly improved, while reducing the complexity of the operation.

[0024] Furthermore, threads with opposite rotation directions are provided on the front and rear sides of the outer side of the screw rod 7, and a separation ring is fixedly connected to the middle of the outer side of the screw rod 7. By providing two sets of threads, the movable frames 10 on both sides can be moved in different directions when the screw rod 7 rotates unidirectionally, so as to realize rapid flattening of the flexible circuit board and improve the flattening speed.

[0025] Furthermore, the height of the side of the movable groove 5 on the same vertical plate 4 that is close to each other is higher than the height of the side that is far away from each other, which limits the trajectory of the movable groove 5. When the rotating rollers 12 are in a position close to each other, the flattening roller 13 does not contact the flexible circuit board, so as to facilitate the material removal of the flexible circuit board and facilitate the material removal operation.

[0026] When the utility model is implemented in detail: first open the protective plate, pull the movable plate 3 to move it out of the processing chamber 2, place the flexible circuit board to be cut on the surface of the movable plate 3 and make it located under the flattening roller 13, then start the motor 18 on the movable plate 3 on the cutting machine body 1 through the controller, drive the screw rod 7 on one side to rotate, and drive the screw rods 7 on both sides to rotate synchronously through the pulley 8 and the belt 9, and the movable frame 10 moves to both sides through the threaded fit between the movable frame 10 and the movable frame 10. During the movement, due to the guidance of the movable groove 5, the rotating roller 12 will move up and down in the movable groove 11, and at the same time drive the flattening roller 13 to contact the surface of the flexible circuit board and proceed. Roller pressing, when the movable frame 10 moves, it will drive the triangular block 14 to move. When the triangular block 14 contacts and pushes the pressure rod 17 to move, it will drive the pressure rod 17 to press down so that it contacts and squeezes the flexible circuit board to fix it. At the same time, the compression spring 16 shortens and deforms, and then pushes the movable plate 3 to make it enter the processing chamber 2, and rotates to close the protective plate. After that, the controller controls the cutting structure to cut the flattened flexible circuit board. After the cutting is completed, the controller controls the output end of the motor 18 to reverse, so that the pressure rod 17 and the flattening roller 13 successively release the fixation of the flexible circuit board, and then open the protective plate, pull the movable plate 3 outward to move it out of the processing chamber 2, and remove the cut flexible circuit board.
