The utility model provides a kind of bending mechanism of flexible circuit board, in a kind of specific embodiment party shown in Fig. 1-3
In formula, bending mechanism includes pressure head 1, briquetting 2 and workbench 3.
The pressure head 1 has raised land 11, the first stitching surface 12 and the first fin 13.The pressure head 1 can be by standard
4 clamping of flexible circuit board of standby bending is soft between workbench 3 and raised land 11 between workbench 3 and raised land 11
Property wiring board 4 is fixed.There is difference of height, first fin 13 is formed between first stitching surface 12 and raised land 11
Formed with the first groove 14 between the edge of raised land 11,13 and first stitching surface 12 of the first fin.
The briquetting 2 has the second stitching surface 21 and the second fin 22, and the briquetting 2 can exist 4 clamping of flexible circuit board
Between second stitching surface 21 and the first stitching surface 12, second fin 22 is formed in the edge of the second stitching surface 21.
Raised land 11 first presses flexible circuit board 4 with workbench 3, as shown in Figure 1；Then the first stitching surface 12 and
Two stitching surfaces 21 press flexible circuit board 4, and flexible circuit board 4 forms certain bending at this time, as shown in Figure 2；Finally, make
Second fin 22 is inserted into first groove 14, as shown in Figure 3,4.22 mating reaction of first fin 13 and the second fin,
It is pointed to extend to the implementation bending operation of flexible circuit board 4 between raised land 11 at the first stitching surface 12.It is described curved
Folding mechanism can make flexible circuit board form bending at two by a bending forming operation.Also, by adjusting the first fin
And second fin shape, or adjust the depth that the first fin is inserted into the first groove, make the bending angle of flexible circuit board
Scope covers 0-180 degree.Thus when flexible circuit board carries out bending forming actual bending angle can be made slightly smaller than advance
The bending angle of setting.After operation is bent, flexible circuit board can produce a certain amount of recovery deformation, by actual curved
The control of dog-ear degree, can make final bending angle of the flexible circuit board after deformation is recovered meet pre-set bending angle
Degree.
Specifically, as shown in figure 3, first fin 13 is arranged to extend towards with the second fin 22, the first fin
13 extend from raised land 11 towards the second fin 22, and the second fin 22 is from the first stitching surface 12 towards the first fin 13
Extend.When coordinating bending flexible circuit board 4, first fin 13 mutually staggers with the second fin 22, while to circuit
Two location points carry out bending on plate 4.The distance to stagger is configured as the thickness more than or equal to flexible circuit board 4, so may be used
Deformed with ensureing that wiring board is coordinated by first fin 13 with the second fin 22 during bending with space, avoid flexible wires
There is the phenomenon that cannot be bent by pressing tension in road plate.
The workbench 3 at the described first 13 corresponding position of bending fin with being additionally provided with concave part 6, described first
When 13 and second fin 22 of fin coordinates bending flexible circuit board 4, the briquetting 2 is moved towards workbench 3.Bent when needs
When angle is smaller, briquetting 2 needs the distance of movement longer, may be inconsistent and immovable with workbench 3, causes flexible wires
Road plate 4 cannot be folded into predetermined angular.The setting of the concave part 6, it is ensured that briquetting 2 is moved from the limitation of workbench 3,
Concave part 6, which is formed, to be avoided, so as to fulfill the bending at any angle of flexible circuit board 4.Alternatively, concave part can also be formed in
On the briquetting 2, the setting of concave part makes the movement of briquetting 2 unrestricted, avoids offseting with workbench 3, and then realize bending
Mechanism bends flexible circuit board at any angle.
The briquetting 2 is provided with the second groove 23, the raised land 11 and work with 13 corresponding position of the first fin
Platform 3 first presses flexible circuit board 4, and then the first stitching surface 12 presses flexible circuit board 4 with the second stitching surface 21, so
After second fin 22 is inserted into first groove 14, the first fin 13 is inserted into second groove 23.So not only may be used
During so that flexible circuit board carrying out bending, it can be carried out at the same time at two and bend, one-pass molding, can also make flexible circuit board in 0-
Angle bending forming between 180 degree.
Rubber block 5 is configured with first groove, 14 and second groove 23, described is inserted into second fin 22
One groove 14, when the first fin 13 is inserted into second groove 23 to flexible circuit board progress bending, the rubber block 5 is to flexibility
The outside of 4 bending part of wiring board forms extruding., mutually can be to bending part after extruding because rubber block deformability is larger
Outside forms parcel shape, and then plays cushioning effect.It can prevent that metal wire therein is (such as when flexible circuit board from bending：Copper wire) folding
It is disconnected, at the same time it can also make the time that flexible circuit board profile angle is kept longer.
The rubber block can be made of polyurethane material, be fitted using the soft or hard degree of rubber block made of polyurethane material
In, it is more preferable to the protecting effect of metal wire when flexible circuit board is bent.Those skilled in the art can also use other
Rubber block is made in material, and the application is without limitation, and every technical solution that can reach similar technology effect, belongs to this Shen
Protection domain please.
As shown in Figs. 1-3, the raised land 11, the first stitching surface 12, the second stitching surface 21 and workbench 3 are parallel to each other
Or close to extending in parallel, flexible circuit board is ensured the accuracy of bending angle in bending, it can also make respectively to match somebody with somebody
Conjunction face fully can press flexible circuit board.
When 12 and second stitching surface 21 of the first stitching surface presses flexible circuit board 4, first pressing
The distance between 12 and second stitching surface 21 of face is greater than or equal to the thickness of flexible circuit board 4, so that flexible circuit board 4 is by the
When one fin 13 and the second fin 22 coordinate bending, the flexible circuit board 4 of the first stitching surface 12 and the pressing of the second stitching surface 21
Divide easy to remove.
The briquetting 2 further includes first position adjusting mechanism and second place adjusting mechanism, and the first position adjusts machine
Structure is configured to press the first stitching surface 12 of the second stitching surface 21 and pressure head 1, the second place adjusting mechanism quilt
It is configured to the second fin 22 is moved towards with the first fin 13.As depicted in figs. 1 and 2, the first position adjusts machine
Structure driving briquetting 2 is moved along perpendicular to the direction of the first stitching surface 12, the first stitching surface 12 and the second stitching surface 21 is matched somebody with somebody combined pressure
Close flexible circuit board 4.As shown in Figures 2 and 3, the first position adjusting mechanism drives briquetting 2 along parallel to the first stitching surface
12 direction movement, makes the first fin 13 and the second fin 22 coordinate bending flexible circuit board 4.
The first position adjusting mechanism, the second adjusting mechanism and pressure head 1 can use air-cylinder type to drive, this area skill
Art personnel can also use other type of drive, and as motor drives, the change of these type of drive, belongs to the protection model of the application
Enclose.
As shown in Figs. 1-3, the first position adjusting mechanism includes jacking block 7 and elastic mechanism, the jacking block 7 and briquetting 2
Connection.Cylinder driving jacking block 7 is moved, and then drives briquetting 2 to move and flexible circuit board 4 is pressed.When the first fin
13 and second fin 22 coordinate bending flexible circuit board 4 after, briquetting 2 is in position as shown in Figure 3, and the elastic mechanism can be with
