Description

Technical Field

[0001] This utility model relates to the field of circuit board bending and forming technology, and in particular to a flexible circuit board bending and forming device. Background Technology

[0002] Flexible printed circuit boards (FPCBs) are printed circuits made of flexible insulating substrates. They have many advantages that rigid printed circuit boards do not have. They can be bent, rolled, and folded freely, arranged arbitrarily according to spatial layout requirements, and moved and stretched arbitrarily in three-dimensional space, thereby achieving the integration of component assembly and wire connection.

[0003] Existing flexible circuit board bending and forming devices typically place the circuit board in a specific mold and then bend it using a bending head. However, this process requires workers to remove the bent circuit board from the mold after each bending before placing the next one, resulting in poor efficiency. Furthermore, manually removing the bent circuit board from the mold after each bending operation is cumbersome. Therefore, we propose a flexible circuit board bending and forming device. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a flexible circuit board bending and forming device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flexible circuit board bending and forming device is designed, including a base, a U-shaped frame is installed on the top of the base, a movable plate is provided inside the U-shaped frame, the top of the movable plate is fixed to the top of the U-shaped frame by a first telescopic mechanism, and a bending head is installed at the bottom of the movable plate.

[0006] The top of the base is also provided with a through groove, and strip mounting plates are installed on both sides of the inside of the through groove. Several support rollers are rotatably connected between two strip mounting plates. The support rollers are connected to each other by a conveyor belt, and one end of one of the support rollers is connected to a drive motor, which is fixed on one side of the base.

[0007] Several molds are installed at equal intervals on the outer surface of the conveyor belt. Each mold has a cavity at the top that matches the bending head. The cavity is located below the bending head, and each cavity has an air vent at the bottom. The other end of the air vent passes through the conveyor belt.

[0008] A support plate is also installed between the two strip mounting plates. The support plate is located between the two support rollers, and the top of the support plate is fitted with the top of the conveyor belt with a clearance.

[0009] Several support legs are installed on the bottom edge of the base, and a base plate is connected between the support legs. An air pump is installed on the top of the base plate. An air supply pipe is connected to the air outlet of the air pump. The other end of the air supply pipe is fixed to the side of the base. An air guide pipe is also installed between two strip mounting plates. The air guide pipe is located between the conveyor belts, and one end of the air guide pipe is connected to the air supply pipe. Several exhaust holes are opened on the side of the air guide pipe, and the exhaust holes face the inner surface of the conveyor belt.

[0010] Preferably, guide rails are installed on both sides of the interior of the U-shaped frame, and both ends of the movable plate are slidably connected to the guide rails via sliders.

[0011] Preferably, the top of the mold extends above the strip mounting plate.

[0017] The design scheme proposed in this utility model has the following beneficial effects in application:

[0018] By installing several molds on the conveyor belt, while the bending head is bending the circuit board in one mold cavity, the operator can simultaneously place the unbent circuit board in other mold cavities, thus improving the efficiency of use.

[0019] An air pump delivers outside air through air pipes and guide pipes into the conveyor belt. The bent circuit boards are then blown out of the cavity through air holes and outlets and fall into the collection box for centralized collection.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-3 A flexible circuit board bending and forming device includes a base 1, a control cabinet 17 installed at the bottom of the base 1, and a controller inside the control cabinet 17, which is either a control motherboard or a PLC logic controller.

[0026] like Figure 1 As shown, a U-shaped frame 8 is installed on the top of the base 1. A movable plate 7 is provided inside the U-shaped frame 8. The top of the movable plate 7 is fixed to the top of the U-shaped frame 8 by a first telescopic mechanism 9, and a bending head 10 is installed at the bottom of the movable plate 7. The first telescopic mechanism 9 is one of an electric push rod, a cylinder, or a hydraulic rod. The first telescopic mechanism 9 is connected to the controller through a wire. In actual use, the high end of the movable plate 7 can be adjusted by extending and retracting the first telescopic mechanism 9, thereby adjusting the position of the bending head 10.

[0027] like Figure 1 and Figure 2As shown, a through groove 11 is also provided on the top of the base 1. Strip mounting plates 21 are installed on both sides of the inside of the through groove 11. Several support rollers 23 are rotatably connected between the two strip mounting plates 21. The support rollers 23 are connected to each other by a conveyor belt 19. One end of one of the support rollers 23 is connected to a drive motor 18. The drive motor 18 is fixed on one side of the base 1. The drive motor 18 is connected to the controller through a guide. In actual use, the drive motor 18 can drive the support roller 23 to rotate, which in turn can drive the conveyor belt 19 to move.

[0028] like Figure 1 and Figure 2 As shown, several molds 3 are equidistantly installed on the outer surface of the conveyor belt 19. Each mold 3 has a cavity 2 at its top that matches the bending head 10. The cavity 2 is located below the bending head 10, and each cavity 2 has an air vent 25 at its bottom. The other end of the air vent 25 passes through the conveyor belt 19. In actual use, the operator can place the flexible circuit board to be bent into the cavity 2, and then the flexible circuit board can be transported to the bending head 10 through the conveyor belt 19. The bending head 10 will then bend the circuit board. In this way, during the bending process, the operator can put other unbent circuit boards into the corresponding cavities 2, thereby improving the usage effect.

[0029] like Figure 1 As shown, the top of the mold 3 extends above the strip mounting plate 21. Each strip mounting plate 21 has an L-shaped positioning plate 5 on its top. One end of each L-shaped positioning plate 5 is fixed to the side of the U-shaped frame 8 by the second telescopic mechanism 14, and the other end of each L-shaped positioning plate 5 extends above the conveyor belt 19. In actual use, the second telescopic mechanism 14 is one of an electric push rod, a cylinder, or a hydraulic cylinder. Each L-shaped positioning plate 5 has a pressure sensor 4 installed on its side. The second telescopic mechanism 14 and the pressure sensor 4 are connected to the controller through wires. When the conveyor belt 19 moves the mold 3 to below the bending head 10, the side of the pressure sensor 4 abuts against the side of the mold 3. In actual use, the extension and retraction of the second telescopic mechanism 14 can control the position of the L-shaped positioning plate 5. Thus, when the mold 3 moves with the conveyor belt 19 to below the bending head 10, the side of the mold 3 will abut against the side of the pressure sensor 4. In this way, the controller can turn off the drive motor 18, and the positioning of the mold 3 can be completed.

[0030] like Figure 2 As shown, a support plate 24 is also installed between the two strip mounting plates 21. The support plate 24 is located between the two support rollers 23, and the top of the support plate 24 is in clearance fit with the top of the inside of the conveyor belt 19. Under the action of the support plate 24, the conveyor belt 19 can be supported. In this way, when the bending head 10 bends the circuit board in the cavity 2, the conveyor belt 19 can remain stable.

[0031] like Figure 2 and Figure 3 As shown, several support legs 20 are installed on the bottom edge of the base 1, and a base plate 16 is connected between the support legs 20. An air pump 26 is installed on the top of the base plate 16. The air pump 26 is connected to the controller via wires. An air supply pipe 12 is connected to the air outlet of the air pump 26. The other end of the air supply pipe 12 is fixed to the side of the base 1. An air guide pipe 22 is also installed between two strip mounting plates 21. The air guide pipe 22 is located between the conveyor belts 19, and one end of the air guide pipe 22 is connected to the air supply pipe 12. Several exhaust holes 27 are provided on the side of the air pipe 22, and the exhaust holes 27 face the inner surface of the conveyor belt 19. In actual use, the air pump 26 can deliver external air to the air guide pipe 22 through the air pipe 12, and then blow it to the bottom of the conveyor belt 19 through the exhaust holes 27. In this way, when the mold 3 containing the bent circuit board moves to the bottom of the conveyor belt 19, the air blown out of the exhaust holes 27 will be blown into the cavity 2 through the air outlet 25, blowing out the circuit board inside the cavity 2.

[0032] like Figure 1 and Figure 2 As shown, a collection box 15 with an upward opening is also installed on the top of the base plate 16. The collection box 15 is located below the through groove 11. In actual use, the circuit boards blown out by air from inside the cavity 2 will fall directly into the collection box 15 for centralized collection.

[0033] Specifically, in use, the operator places the flexible circuit board to be bent into the cavity 2, and then controls the drive motor 18 to work through the controller. The drive motor 18, under the action of the support roller 23, drives the conveyor belt 19 to move, so that the mold containing the circuit board moves into the U-shaped frame 8. When the mold 3 moves to the preset position inside the U-shaped frame 8, one side of the mold 3 will abut against the pressure sensor 4 on the side of the L-shaped positioning plate 5. The pressure sensor 4 transmits the detected data to the controller, and the controller then turns off the drive motor 18 and simultaneously controls the first telescopic mechanism 9 and the second telescopic mechanism 14 to work. The second telescopic mechanism 14 retracts, causing the L-shaped positioning plate 5 to move horizontally, so that the L-shaped positioning plate 5 moves away from the top of the conveyor belt 19. At the same time, the first telescopic mechanism 9 extends, pushing the moving plate 7 to move. The moving plate 7 drives the bending head 10 to move, so that the bottom of the bending head 10 moves into the cavity 2 to mechanically bend the circuit board in the cavity 2. During the bending process, the operator can place other circuit boards to be bent into the cavity. The circuit board is inserted into the cavity 2 of another mold 3 fixed on the top of the conveyor belt 19. After bending, the controller controls the first telescopic mechanism 9 to retract, moving the bottom of the bending head 10 out of the cavity 2. Then, the controller controls the drive motor 18 to work, which drives the conveyor belt 19 to move, moving the bent circuit board out from under the U-shaped frame 8. When the mold 3 containing the bent circuit board moves out from under the U-shaped frame 8, the controller controls the second telescopic mechanism 14 to extend, moving one end of the L-shaped positioning plate 5 to... Above the conveyor belt 19, the mold 3 is positioned. When the mold 3 containing the bent circuit board moves below the conveyor belt 3, the controller controls the air pump 26 to work. The air pump 26 delivers external air through the air pipe 12 to the air guide pipe 22, and then blows it into the conveyor belt 19 through the exhaust hole 27. The flowing air will also blow it into the surface of the circuit board inside the cavity 2 through the air outlet 25, blowing the circuit board out of the cavity 2 and letting it fall into the collection box 15 below for collection under gravity, making material retrieval convenient.

[0034] Furthermore, such as Figure 1 As shown, guide rails 6 are installed on both sides of the interior of the U-shaped frame 8. Both ends of the movable plate 7 are slidably connected to the guide rails 6 through sliders. Under the action of the guide rails 6, the movable plate 7 can be limited, so that the movable plate 7 remains stable.

[0035] Furthermore, such as Figure 1 As shown, at least one guide rod 13 is vertically installed on one side of each L-shaped positioning plate 5. One end of each guide rod 13 slides through the side of the U-shaped frame 8. The guide rod 13 can limit the L-shaped positioning plate 5, so that the L-shaped positioning plate 5 remains stable.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
