Technical Field

[0001] The utility model relates to the technical field of flexible circuit board processing, in particular to a flexible circuit board bending device. Background Art

[0002] A flexible printed circuit (FPC), also known as a flexible circuit board or a flexible printed circuit board, is favored for its excellent characteristics such as light weight, thin thickness, and free bending and folding. It is a highly reliable and extremely flexible printed circuit board made of polyimide or polyester film as the substrate, which can greatly reduce the volume and weight of electronic products and meet the needs of the development of electronic products towards high density, miniaturization, and high reliability. Therefore, FPC has been widely used in fields or products such as aerospace, military, mobile communication, laptop computers, computer peripherals, PDAs, digital cameras, etc.

[0003] In the existing operation technology, when bending a flexible circuit board, most devices bend one flexible circuit board at a time and can only bend it into one shape, resulting in a low efficiency of bending the flexible circuit board, which may affect the subsequent work of the flexible circuit board and reduce its practicability.

A driving rod is arranged at the power output end of the cylinder. An upper pressing plate is arranged at the lower surface of the driving rod. Square grooves are formed on both sides of the upper surface of the upper pressing plate.

[0007] At the bottom position of the inner wall of the square groove, a fixed sleeve is arranged, and the number of fixed sleeves is four. A threaded sleeve is arranged inside the fixed sleeve. A stamping block is fixedly connected to the lower surface of the threaded sleeve. A limit bolt is threadedly connected inside the threaded sleeve.

[0008] Preferably, auxiliary lifting rods are arranged on both sides of the upper surface of the load-bearing plate, and a limit frame is fixedly connected to the lower surface of the auxiliary lifting rods.

[0009] Preferably, support columns are fixedly connected to the left and right sides of the lower surface of the load-bearing plate, and a fixing plate is fixedly connected to the lower surface of the support columns, and the number of fixing plates is two.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] When an operator uses the device for work, multiple flexible circuit boards can be placed on the upper surface of the movable pressing plate, and then the air cylinder is started. The power output end of the air cylinder will move downward, driving the driving rod and the upper pressing plate to also move downward, so as to bend multiple flexible circuit boards. Moreover, the shapes of the punching blocks are different. If flexible circuit boards of different shapes are needed, the punching blocks can be replaced at any time, and multiple flexible circuit boards can be bent into different shapes at the same time, improving the efficiency of bending flexible circuit boards, reducing the work burden of the operator, accelerating the efficiency of subsequent work of the flexible circuit boards, and increasing the practicability.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Embodiment 1

[0023] Referring to Figures 1-4 , a flexible circuit board bending device includes a load-bearing plate 1. A cylinder 2 is arranged at the middle position of the upper surface of the load-bearing plate 1. A driving rod 3 is arranged at the power output end of the cylinder 2. A upper pressing plate 4 is arranged on the lower surface of the driving rod 3. Square grooves 5 are formed on both sides of the upper surface of the upper pressing plate 4;

[0024] At the bottom position of the inner wall of the square groove 5, there are fixed sleeves 6, and the number of the fixed sleeves 6 is four. A threaded sleeve 7 is arranged inside the fixed sleeve 6. A stamping block 8 is fixedly connected to the lower surface of the threaded sleeve 7. A limit bolt 9 is threadedly connected inside the threaded sleeve 7. Auxiliary lifting rods 10 are arranged on both sides of the upper surface of the load-bearing plate 1. A limit frame 11 is fixedly connected to the lower surface of the auxiliary lifting rod 10. Support columns 12 are fixedly connected to the left and right sides of the lower surface of the load-bearing plate 1. A fixing plate 13 is fixedly connected to the lower surface of the support column 12, and the number of the fixing plates 13 is two. A workbench 14 is fixedly connected to the lower surface of the fixing plate 13. A support frame 15 is fixedly connected to the middle position of the upper surface of the workbench 14. A moving guide rail 16 is fixedly connected to the upper surface of the support frame 15, and the number of the moving guide rails 16 is five. The left and right sides of the moving guide rail 16 are movably connected to a movable pressing plate 17 through sliders 19. A pulling frame 18 is fixedly connected to the middle position of the front surface of the movable pressing plate 17. A placing plate 20 is fixedly connected to the front surface of the workbench 14. A controller 21 is arranged on the upper surface of the placing plate 20.

[0025] In the existing operation technology, when bending a flexible circuit board, most devices bend one flexible circuit board at a time and can only bend it into one shape. The efficiency of bending the flexible circuit board is low, which may affect the subsequent work of the flexible circuit board and reduce the practicability.

[0026] When an operator uses this device to work, multiple flexible circuit boards can be placed on the upper surface of the movable pressing plate 17, and then the cylinder 2 is started. The power output end of the cylinder 2 will move downward, causing the driving rod 3 to also move downward, so that the driving rod 3 will drive the upper pressing plate 4 to also move downward, thereby bending the multiple flexible circuit boards on the upper surface of the movable pressing plate 17;

[0027] If flexible circuit boards of different shapes are needed, the operator can remove the stamping block 8 from the lower surface of the upper pressing plate 4, and then install the stamping block 8 of the corresponding shape on the lower surface of the upper pressing plate 4 through the fixed sleeve 6, the threaded sleeve 7 and the limit bolt 9. Since the shapes of the stamping blocks 8 are different, multiple flexible circuit boards can be bent into different shapes at the same time, improving the efficiency of bending the flexible circuit boards, reducing the workload of the operator, accelerating the efficiency of the subsequent work of the flexible circuit boards, and increasing the practicability.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
