Connected by rotating shaft；The LCDs placement platform is provided with the cavity for housing LCDs, the flexible print
Brush wiring board is provided with and the flexible print circuit board shape identical alignment grooves for being bent to bit platform, and the alignment grooves are extended to
Flexible print circuit board needs the position and the one end in the flexible print circuit board to bit platform away from rotating shaft of bending to be formed
Opening.When using, LCM fixed platforms are placed, lift FPC to bit platform, LCM is placed on above platform, by the FPC of LCD
Launch to place, put down FPC to bit platform, FPC is folded over to come, along FPC alignment grooves para-position bending.
Further, above-mentioned flexible print circuit board on the outside of bit platform to being provided with for the handss of this pair of bit platform of folding
Handle.
Further, above-mentioned LCDs placement platform is provided with the both sides of the cavity and conveniently take liquid crystal display
The groove of screen.
Further, the wall of above-mentioned alignment grooves passes through chamfered transition with flexible print circuit board to the top end face of bit platform
Connection, the inclined-plane can prevent FPC that damage is torn into after alignment grooves.
Further, above-mentioned inclined-plane and the flexible print circuit board be 20 ° to the angle that the bottom surface of bit platform is formed-
35°。
Further, the angle that above-mentioned inclined-plane is formed with the flexible print circuit board to the bottom surface of bit platform is 30 °.
Further, above-mentioned rotating shaft is fixed on the LCDs placement platform by two fixed blocks.
Further, above-mentioned flexible print circuit board is 6mm-8mm to the thickness of bit platform, and too thin pressure is bad, too thick to take
Material and not handy.
This utility model has following beneficial technique effect：1) para-position is bent to FPC using this fixture, it is simple to operate,
Ensure that FPC, along FPC alignment grooves accurate contrapositions, can be accurate to ± 0.2mm, do not result in FPC off normals, tear, Bu Huizao
Crush into product, scratch, falling the problems such as painting；2) this fixture is conducive to protecting the surrounding integrity of LCD, prevents breakage；3) this folder
Tool can mitigate the action dynamics during FPC bendings, it is ensured that FPC integrity, be less prone to FPC tears, disrepair phenomenon.

【Specific embodiment】
Below in conjunction with specific embodiment, this utility model is described further.
Embodiment provided below and being not used to limits the scope that this utility model is covered, and described step is not yet
It is to limit its execution sequence.Those skilled in the art do to this utility model with reference to existing common knowledge and obviously change
Enter, also fall within the protection domain of this utility model requirement.
Embodiment
A kind of flexible print circuit board bends positioning fixture, as Figure 1-3, including the He of LCDs placement platform 1
To bit platform 2, the LCDs placement platform 1 and the flexible print circuit board are to bit platform 2 for flexible print circuit board
One end connected by rotating shaft 3；The LCDs placement platform 1 is provided with the cavity 4 for housing LCDs, institute
State the flexible print circuit board shape identical alignment grooves 5 that flexible print circuit board is provided with to bit platform 2 and is bent, this pair
Position groove 5 extend to flexible print circuit board need bending position and the flexible print circuit board to bit platform 2 away from turn
One end of axle 3 forms opening.
When using, LCM fixed platforms 1 are placed, lift FPC to bit platform 2, LCM is placed in cavity 4, by LCD's
FPC launches to place, and puts down FPC to bit platform 2, FPC is folded over to come, along the para-position of FPC alignment grooves 5 bending.
