[0031] 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 one embodiment of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0032] Please refer to Figures 1 to 10 , the present utility model provides a flexible circuit board bending device.

[0033] Specifically, as Figure 1 shown, four positioning holes 21 are provided on one side of the flexible circuit board 2, which facilitates subsequent positioning and bending of the flexible circuit board 2.

[0034] As Figure 2 shown, it is a schematic diagram of the effect of bending the flexible circuit board 2 inward by 90°; after the flexible circuit board 2 passes through the bending device, the right side of the flexible circuit board 2 is bent upward by 90°.

[0035] In this embodiment, as Figure 3 shown, the bending device is placed horizontally. In other embodiments, it can also be placed vertically. Here, the horizontal placement is taken as an example.

[0036] As Figure 3 shown, the bending device includes a frame 1. The frame 1 is a double-layer frame, and the frame 1 includes a first placement plate 11 and a second placement plate 12 installed on the upper part of the first placement plate 11; the first placement plate 11 and the second placement plate 12 are fixedly connected by a support rod 13 to form an integral body; thus, it is convenient for the subsequent placement and installation of the first vertical cylinder 35; it is also convenient to carry or transplant the whole bending device, and it is inclined to be made into a standard part.

[0037] As Figure 3 shown, a horizontal adjustment plate 91 is installed on the upper part of the second placement plate 12, and the horizontal adjustment plate 91 is horizontally placed and installed with the second placement plate 12; as Figure 6 shown, a plurality of horizontal sliders 93 are installed at the bottom of the horizontal adjustment plate 91. The horizontal sliders 93 are sleeved on a horizontal slide rail 94. The horizontal slide rail 94 is installed on the second placement plate 12, and the horizontal adjustment plate 91 moves horizontally along the horizontal slide rail 94 through the horizontal sliders 93.

[0038] Furthermore, as Figure 3 shown, in order to facilitate fine-tuning the horizontal position of the horizontal adjustment plate 91, a horizontal adjustment mechanism 92 for adjusting the horizontal position of the horizontal adjustment plate 91 is installed on one side of the horizontal adjustment plate 91. The horizontal adjustment mechanism 92 is installed on the frame 1. In this embodiment, the horizontal adjustment mechanism 92 is a micrometer. Rotating and adjusting the micrometer can horizontally adjust the horizontal position of the horizontal adjustment plate 91, and it can move closer to or away from the placement seat 3; furthermore, in other embodiments, the horizontal adjustment mechanism 92 can adopt a horizontal movement module to accurately control the output, so as to horizontally adjust the horizontal position of the horizontal adjustment plate 91.

[0039] As Figure 5As shown, in order to fix the transverse adjustment plate 91 so that the transverse adjustment plate 91 has a stable transverse position, a fixing block 95 is installed on the side of the transverse adjustment plate 91, and the transverse adjustment plate 91 is fixed to the frame 1 through the fixing block 95. In order to adapt to the transverse adjustment mechanism 92, a U-shaped adjustment groove 96 is provided on the fixing block 95.

[0040] like Figure 6 As shown, a placement seat 3 for placing the flexible circuit board 2 is installed on the second placement plate 12, and the placement seat 3 cannot be moved and adjusted unless the specifications are changed; a bending plate 4 for bending the flexible circuit board 2 is installed on one side of the placement seat 3, and the bending plate 4 is transmission-connected to the transverse adjustment plate 91, and the bending plate 4 can be adjusted together with the transverse adjustment plate 91; the bending plate 4 can be rotated to bend one end of the flexible circuit board 2; a device for pressing one end of the flexible circuit board 2 is also installed above the placement seat 3. The pressing plate 5 is connected to the lateral adjustment plate 91 by transmission, and the pressing plate 5 can also be adjusted together with the lateral adjustment plate 91; when the flexible circuit board 2 is placed manually or automatically, one end of the flexible circuit board 2 is placed on the placement seat 3, and the other end is placed on the bending plate 4; the bending position of the flexible circuit board 2 is just between the placement seat 3 and the bending plate 4; the pressing plate 5 moves vertically downward to press one end of the flexible circuit board 2, and the bending plate 4 rotates toward one side of the placement seat 3 to bend the other end of the flexible circuit board 2.

[0041] Furthermore, in this embodiment, the bending angle of the flexible circuit board 2 is 90°; however, in other embodiments, a suitable bending angle can be selected according to the actual situation on site. In theory, the bending angle can be an acute angle or an obtuse angle.

[0042] like Figure 9 As shown, the placement seat 3 is provided with a plurality of vacuum adsorption holes 31, and the vacuum adsorption holes 31 are evenly distributed, and the flexible circuit board 2 is placed on one end of the placement seat 3 for vacuum adsorption and fixation. Furthermore, the vacuum adsorption holes 31 can also be adaptively changed and modified according to the shape or specification of the flexible circuit board 2.

[0043] like Figure 4 As shown, the placement seat 3 is also provided with a plurality of positioning posts 32 , which pass through the flexible circuit board 2 and position the flexible circuit board 2 ; the positioning posts 32 are configured to be vertically retractable, and the ends of the positioning posts 32 are provided with inclined surfaces 33 .

[0044] In this embodiment, one end of the flexible circuit board 2 is first placed on the placement seat 3, and the other end is placed on the bending plate 4; the placement seat 3 is preferably provided with a vacuum adsorption hole 31 and a positioning column 32, and the number of the positioning columns 32 is at least two, and the flexible circuit board 2 passes through the positioning columns 32 and is fixedly adsorbed on the placement seat 3, wherein the positioning columns 32 are vertically retractable, that is, they can emerge from the placement seat 3 or retract from the placement seat 3, so that it will be more convenient to automatically place the flexible circuit board 2 on the placement seat 3, and the bottom of the positioning column 32 can be provided with an elastic component, and when the surface applies pressure to the positioning column 32, the positioning column 32 can be retracted from the top of the placement seat 3.

[0045] Specifically, when the manipulator sucks and places the flexible circuit board 2 on the placement seat 3, the positioning piece on the manipulator can be aligned with the positioning column 32 and pressed down. At this time, when the manipulator places the flexible circuit board 2 on the placement seat 3, the vacuum adsorption hole 31 sucks the flexible circuit board 2, and then the manipulator leaves, and the positioning column 32 protrudes from the placement seat 3 and extends into the positioning hole 21 of the flexible circuit board 2, thereby improving the stability and reliability of the flexible circuit board 2 fixed on the placement seat 3.

[0046] In addition, the number of vacuum adsorption holes 31 can be several, which are respectively located at various parts of the flexible circuit board 2, so as to facilitate the adsorption of various parts of the flexible circuit board 2 and improve the reliability of adsorption of the flexible circuit board 2. The vacuum adsorption holes 31 are connected to the suction port of the external vacuum equipment, so that the flexible circuit board 2 can be adsorbed by controlling the suction operation of the external equipment.

[0047] The present embodiment is also preferably provided with a fixing seat for fixing the placement seat 3, and the fixing seat is mounted on the second placement plate 12; the placement seat 3 is mounted on the fixing seat, which is convenient for fixing the placement seat 3 and can also replace different placement seats 3 according to different types of flexible circuit boards 2, so as to facilitate the bending of different types of flexible circuit boards 2 in the present embodiment.

[0048] like Figure 7 As shown, the pressing plate 5 is transmission-connected with the second vertical cylinder 51 , and the pressing plate 5 is mounted at the end of the second vertical cylinder 51 , and the second vertical cylinder 51 drives the pressing plate 5 to reciprocate vertically.

[0049] In other embodiments, the second vertical cylinder 51 can be replaced with a linear drive module, which can also drive the pressing plate 5 to vertically reciprocate, making the movement more precise, but at a higher cost.

[0050] Further, a first transverse cylinder 52 is installed at the lower part of the second vertical cylinder 51. The second vertical cylinder 51 is in transmission connection with the first transverse cylinder 52. The first transverse cylinder 52 drives the first transverse cylinder 52 and the pressing plate 5 to move horizontally back and forth.

[0051] As Figure 5 shown, the first transverse cylinder 52 is installed on the transverse adjustment plate 91, so that the first transverse cylinder 52, the second vertical cylinder 51 and the pressing plate 5 can all move horizontally along with the transverse adjustment plate 91, so as to move away from or close to the placement seat 3 together, and can also adapt to flexible circuit boards 2 of different specifications.

[0052] Furthermore, in order to avoid the positioning posts 32, a plurality of U-shaped grooves 53 for accommodating the positioning posts 32 are provided on the pressing plate 5; when the first transverse cylinder 52 drives the pressing plate 5 to move horizontally, the positioning posts 32 enter the interior of the U-shaped grooves 53, so that the two do not interfere with each other.

[0053] As Figure 9 shown, a plurality of ejector posts 34 are accommodated inside the placement seat 3. The ejector posts 34 move vertically upward, pass through the placement seat 3, and vertically eject the bent flexible circuit board 2; thus, it is convenient for the bent flexible circuit board 2 to be unloaded and leave the placement seat 3; the ejector posts 34 eject the flexible circuit board 2 out of the range of the positioning posts 32, so as to leave the placement seat 3, so that the flexible circuit board 2 can be sucked by a vacuum suction nozzle or manually picked up.

[0054] Further, as Figure 10 shown, the ejector posts 34 are in transmission connection with a first vertical cylinder 35. The ejector posts 34 are installed at the end of the first vertical cylinder 35. The first vertical cylinder 35 is installed on the first placement plate 11. The first vertical cylinder 35 drives the ejector posts 34 to move vertically upward, eject the flexible circuit board 2 out of the range of the positioning posts 32, so as to leave the placement seat 3 and enter the next process.

[0055] As Figure 3 and Figure 5 shown, the bending plate 4 can be directly connected to a motor, and the rotational movement of the motor is used to drive the bending plate 4 to rotate.

[0056] In this embodiment, a first rotating shaft 41 and a second rotating shaft 42 are respectively installed on both sides of the bending plate 4; the second rotating shaft 42 is installed inside a second support block 43, and the first rotating shaft 41 is installed inside a first support block 44. The first support block 44 and the second support block 43 are respectively installed on both sides and are used to support the rotational movement of the bending plate 4, the first rotating shaft 41, and the second rotating shaft 42; the first support block 44 and the second support block 43 are both installed on a lateral adjustment plate 91, so that the first support block 44, the second support block 43, the bending plate 4, the first rotating shaft 41, and the second rotating shaft 42 can all be laterally adjusted together with the lateral adjustment of the lateral adjustment plate 91.

[0057] As Figure 8 shown, a rotating gear 45 is fixedly installed on the first rotating shaft 41. The first rotating shaft 41 and the rotating gear 45 rotate together. A rack 46 is meshed and installed on the upper part of the rotating gear 45. The rotating gear 45 and the rack 46 are both installed inside the first support block 44. In this embodiment, by using the horizontal movement of the rack 46, the gear 45, the bending plate 4, the first rotating shaft 41, and the second rotating shaft 42 are driven to rotate.

[0058] Furthermore, the rack 46 is in transmission connection with a second lateral air cylinder 47. The rack 46 is installed at the end of the second lateral air cylinder 47. The second lateral air cylinder 47 drives the rack 46 to reciprocate horizontally, and through the meshing transmission between the rack 46 and the rotating gear 45, the first rotating shaft 41, the bending plate 4, and the second rotating shaft 42 are driven to rotate, and one end of the flexible circuit board 2 is bent.

[0059] In other embodiments, the second lateral air cylinder 47 can be replaced with a linear drive module, which can also achieve driving the rack 46 to reciprocate horizontally, making the movement more precise, but the cost is higher.

[0060] The second lateral air cylinder 47 drives the rack 46 to move in the lateral direction, thereby driving the rotating gear 45 to rotate. The rotation of the rotating gear 45 drives the first rotating shaft 41 and the second rotating shaft 42 to rotate. At this time, the bending plate 4 will rotate with the rotation of the rotating shaft, and thus the bending operation can be performed. In this embodiment, the rotation angle of the bending plate 4 can be controlled by controlling the moving distance of the rack 46 driven by the second lateral air cylinder 47 in the lateral direction, so as to facilitate controlling the bending angle of the flexible circuit board 2.

[0061] Furthermore, in order to match the first support block 44 and the second support block 43, the second lateral air cylinder 47 is also installed on the lateral adjustment plate 91 and moves laterally together with the lateral adjustment plate 91.

[0062] In order to make the transverse movement of the rack 46 smoother and eliminate the movement vibration and swing of the second transverse cylinder 47, a guiding groove 48 is provided on the first support block 44. The guiding groove 48 is internally provided with the rack 46. Driven by the second transverse cylinder 47, the rack 46 reciprocates horizontally along the guiding groove 48. The guiding groove 48 restricts other degrees of freedom of the rack 46, making the movement smoother and the bending more stable and smooth.

[0063] As Figure 6 shown, a first rolling bearing 49 is provided between the first rotating shaft 41 and the first support block 44, and a second rolling bearing 81 is provided between the second rotating shaft 42 and the second support block 43. Among them, the first rolling bearing 49 rotates within the first support block 44, and the second rolling bearing 81 rotates within the second support block 43. The rolling bearing can reduce the friction between the rotating shaft and the support block during rotation.

[0064] As Figure 3 shown, a rotating position limiting block 82 is provided at the end of the first rotating shaft 41. The rotating position limiting block 82 is provided on one side of the first support block 44. A first adjustable limit 83 is provided on one side of the rotating position limiting block 82, and a second adjustable limit 84 is provided on the other side. The first adjustable limit 83 and the second adjustable limit 84 are also provided on the transverse adjusting plate 91 and move horizontally together with the transverse adjusting plate 91.

[0065] The first adjustable limit 83 limits one side of the rotating position limiting block 82, and the second adjustable limit 84 limits the other side of the rotating position limiting block 82. Controlling the initial position and the end position of the rotating position limiting block 82 also facilitates controlling the rotation angle of the bending plate 4, and thus facilitates controlling the bending angle of the flexible circuit board 2.

[0066] The first adjustable limit 83 and the second adjustable limit 84 rotate through threads to adjust the overall vertical height, thereby controlling the rotation range of the rotating position limiting block 82.

[0067] The movement steps of the bending device:

[0068] Step S1: The placement seat 3 and the bending plate 4 are placed horizontally, and the positioning post 32 protrudes vertically. The automatic manipulator moves the flexible circuit board 2 above the placement seat 3 and the bending plate 4;

[0069] Step S2: The automatic manipulator presses the positioning post 32 to attach the flexible circuit board 2 to the placement seat 3 and the bending plate 4. The vacuum suction holes 31 perform vacuum suction on the flexible circuit board 2. Then, after the automatic manipulator leaves, the positioning post 32 will protrude from the placement seat 3 and extend into the positioning hole 21 of the flexible circuit board 2, thereby fixing the flexible circuit board 2.

[0070] Step S3: Driven by the second vertical cylinder 51, the pressing plate 5 is at a certain vertical height; the first horizontal cylinder 52 drives the first horizontal cylinder 52 and the pressing plate 5 to move horizontally, so that the positioning post 32 enters the U-shaped groove 53, enabling the pressing plate 5 to cover one end of the flexible printed circuit board 2.

[0071] Step S4: The second vertical cylinder 51 drives the pressing plate 5 to move vertically downward, approaching the flexible printed circuit board 2, so that the pressing plate 5 presses on one end of the flexible printed circuit board 2.

[0072] Step S5: The second horizontal cylinder 47 drives the rack 46 to move horizontally, and through the meshing transmission between the rack 46 and the rotating gear 45, drives the first rotating shaft 41, the bending plate 4 and the second rotating shaft 42 to rotate, bending one end of the flexible printed circuit board 2.

[0073] Step S6: After the flexible printed circuit board 2 is bent, the bending plate 4 and the pressing plate 5 are reset in sequence, the vacuum adsorption holes 31 disconnect the adsorption, and the first vertical cylinder 35 drives the ejecting post 34 to move vertically upward, ejecting the flexible printed circuit board 2 out of the range of the positioning post 32, so as to leave the placement seat 3 and enter the next process.

[0074] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
