[0003] In the processing of existing flexible circuit boards, it is necessary to cut off the redundant parts after printing the circuit. However, currently, when cutting the flexible printed circuit, due to the soft texture of the flexible printed circuit, when cutting, the flexible printed circuit will be deformed or displaced under force, resulting in poor cutting position accuracy. And after cutting, generally, it is necessary for workers to manually clean up the cut redundant materials, which is troublesome. For this reason, we propose a processing device for a flexible printed circuit board that prevents deformation. Content of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Refer to Figures 1-4 , a flexible printed circuit board processing device for preventing deformation, including a base 1, a control box 28 is installed on one side of the bottom of the base 1, and a controller is installed in the control box 28. The controller is one of a control main board, a host or a PLC logic controller.

[0027] As Figure 1 and Figure 2 shown, a through groove 2 is opened on the top of the base 1, a moving seat 17 is arranged inside the through groove 2, second fixing blocks 25 are installed at the bottom of the moving seat 17 and one end of the bottom of the through groove 2 respectively, and the two second fixing blocks 25 are connected by a third telescopic mechanism 18. The third telescopic mechanism 18 is connected to the controller through a wire. A placing table 15 is installed at one end of the top of the moving seat 17, and a flexible printed circuit board is placed on the placing table 15. The placing table 15 matches the shape of the flexible printed circuit board. During actual use, the staff can place the flexible printed circuit board to be cut in the placing table 15, and then control the third telescopic mechanism 18 to move the placing table 15 to a preset position in the through groove 2 through the controller.

[0028] It should be noted that, as Figure 1As shown, both sides of the moving seat 17 are slidably connected to the slide rails fixed on both sides inside the through groove 2 through sliders. During actual use, the moving seat 17 can be limited by the slide rails, so that the moving seat 17 remains stable.

[0029] As Figure 1 shown, a U-shaped frame 3 is installed on the top of the base 1. A strip-shaped moving plate 6 is arranged inside the U-shaped frame 3. Both ends of the strip-shaped moving plate 6 are slidably connected to the tracks fixed on both sides inside the U-shaped frame 3 through sliders. The top of the strip-shaped moving plate 6 is connected to the U-shaped frame 3 through a first telescopic mechanism 4. The first telescopic mechanism 4 is connected to the controller through a wire. A pressing block 10 matching the flexible printed circuit board is installed at the bottom of the strip-shaped moving plate 6 through a strip-shaped connecting seat 12. During actual use, the pressing block 10 can be moved downward through the first telescopic mechanism 4, so that the pressing block 10 presses on the flexible printed circuit board, and the flexible printed circuit board is tightly pressed and fixed. In this way, when cutting, the flexible printed circuit board will not be deformed.

[0030] It should be noted that a buffer pad is provided at the bottom of the pressing block 10. The buffer pad can be buffer rubber or other buffer materials. During actual use, when the bottom of the pressing block 10 presses on the flexible printed circuit board, it will be buffered through the buffer pad to prevent the pressing block 10 from damaging the flexible printed circuit board.

[0031] As Figure 1 and Figure 4 shown, first fixing blocks 11 are installed on both sides of the strip-shaped moving plate 6. A second telescopic mechanism 9 is installed on the top of each first fixing block 11. One ends of the two second telescopic mechanisms 9 are connected to the mounting plate 8. The second telescopic mechanism 9 is connected to the controller through a wire. An opening groove 24 matching the shape of the pressing block 10 is formed at the top of the mounting plate 8. The bottom of the pressing block 10 extends into the opening groove 24, and a cutting knife 23 is further installed at the bottom of the mounting plate 8, and the edge of the cutting knife 23 is flush with the edge of the opening groove 24. During actual use, after the pressing block 10 tightly presses and fixes the flexible printed circuit board, the staff then controls the second telescopic mechanism 9 through the controller to control the cutting knife 23 to move downward, so that the cutting knife 23 cuts off the redundant parts on the flexible printed circuit board to complete the processing.

[0032] As Figure 1 and Figure 3As shown in the figure, a vacuum pump 5 is installed on one side of the top of the strip-shaped moving plate 6. The vacuum pump 5 is connected to the controller through a wire. The air inlet end of the vacuum pump 5 is connected to an air suction pipe 7. The other end of the air suction pipe 7 is fixed to the top of the mounting plate 8. A gas collection cavity 27 is formed inside the mounting plate 8. The gas collection cavity 27 is communicated with the air suction pipe 7. Adsorption holes 26 are formed on both sides of the bottom of the mounting plate 8. The adsorption holes 26 are communicated with the gas collection cavity 27. After the cutting is completed, the controller can control the vacuum pump 5 to work. The vacuum pump 5 sucks out the gas in the gas collection cavity 27 through the air suction pipe 7, so that the adsorption holes 26 generate suction force to adsorb the cut material.

[0033] As Figure 1 and Figure 2 shown in the figure, a blanking groove 22 is formed at the other end of the top of the moving seat 17. A plurality of legs 19 are equidistantly installed on both sides of the bottom of the base 1. A storage plate 20 is further provided at the bottom of the base 1. The storage plate 20 is located directly below the U-shaped frame 3. The edge of the storage plate 20 is fixed to the legs 19. A collection box 21 is provided on the top of the storage plate 20. The top opening of the collection box 21 is located below the through groove 2. During actual use, after the adsorption holes 26 adsorb and fix the cut material, the staff controls the second telescopic mechanism 9 and the first telescopic mechanism 4 to contract through the controller. The second telescopic mechanism 9 controls the mounting plate 8 and the cutter 23 to move above the bottom of the pressing block 10. Then the first telescopic mechanism 4 moves the pressing block 10 away from the surface of the flexible printed circuit board. Then the third telescopic mechanism 18 moves the placement table 15 to one end of the through groove 2. At the same time, the blanking groove 22 moves below the mounting plate 8. Then the vacuum pump 5 is turned off, and the suction force of the adsorption holes 26 disappears. The material adsorbed by the adsorption holes 26 can fall into the blanking groove 22 under the action of gravity and finally pass through the blanking groove 22 and fall into the collection box 21 for collection.

[0034] It should be noted that when the placement table 15 moves to one end of the through groove 2, the blanking groove 22 moves between the mounting plate 8 and the collection box 21. In this way, when the placement table 15 is moved to one end of the through groove 2 for loading and unloading, the blanking groove 22 will move between the mounting plate 8 and the collection box 21, which is convenient for discharging the material adsorbed by the adsorption holes 26 into the collection box 21 for collection.

[0035] It should be noted that the first telescopic mechanism 4, the second telescopic mechanism 9 and the third telescopic mechanism 18 are all one of an electric push rod, a cylinder or a hydraulic rod.

[0036] Specifically, when the utility model is in use, the staff places the flexible printed circuit board to be cut on the placement table 15, and then controls the third telescopic mechanism 18 to extend through the controller. The third telescopic mechanism 18 pushes the moving seat 17 to move along the through groove 2, and moves the placement table 15 to a preset position below the mounting plate 8. After that, the controller controls the first telescopic mechanism 4 to work. The first telescopic mechanism 4 pushes the strip-shaped moving plate 6 downward, so that the bottom of the pressing block 10 presses on the flexible printed circuit board, and the flexible printed circuit board is tightly pressed and fixed. Then, the controller controls the second telescopic mechanism 9 to extend. The second telescopic mechanism 9 pushes the mounting plate 8 to move downward, and the mounting plate 8 drives the cutting knife 23 to move downward to cut off the excess material on the flexible printed circuit board. After cutting, the staff controls the vacuum pump 5 to work through the controller. The vacuum pump 5 sucks out the air in the air collection cavity 27 through the air suction pipe 7, so that a negative pressure is generated in the air collection cavity 27, and the suction holes 26 generate suction force to adsorb and fix the cut material. Then, the controller controls the second telescopic mechanism 9 to contract, and the mounting plate 8 drives the material adsorbed by the suction holes 26 to separate from the placement table 15. Then, the controller controls the first telescopic mechanism 4 to contract to move the pressing block 10 away from the flexible printed circuit board. Then, the controller controls the third telescopic mechanism 18 to contract to move the placement table 15 to one end of the through groove 2. At the same time, the material falling groove 22 opened at the other end of the moving seat 17 moves below the mounting plate 8. The controller turns off the vacuum pump 5, and the suction force of the suction holes 26 disappears. The material adsorbed by the suction holes 26 falls into the collection box 21 below through the material falling groove 22 under the action of gravity to complete the collection.

[0037] Furthermore, as Figure 1 shown, a limiting frame 16 is installed at the top edge of the placement table 15. In this way, when in use, when the staff places the flexible printed circuit board on the placement table 15, the limiting frame 16 will limit the edge of the flexible printed circuit board to prevent the position of the flexible printed circuit board from shifting when the placement table 15 moves.

[0038] Furthermore, as Figure 1 shown, a guiding frame 14 is installed at one end of the top of the moving seat 17 near the material falling groove 22. The guiding frame 14 is provided with a wide mouth, and the bottom of the guiding frame 14 is flush with the top edge of the material falling groove 22. In actual use, the guiding frame 14 can increase the size of the top opening of the material falling groove 22, so as to prevent the material adsorbed by the suction holes 26 from scattering outside the material falling groove 22.

[0039] Furthermore, as Figure 1 shown, at least one guiding rod 13 is also installed on the top of the mounting plate 8. The top of each guiding rod 13 slidably penetrates through the strip-shaped moving plate 6. Under the action of the guiding rod 13, the mounting plate 8 can be limited to keep it stable.

[0040] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
