Description
[technical field]
The utility model relates to flexible PCB processing technique field, particularly a kind of tool that reduces angular deflection problem in multiple tracks bending.
[background technology]
Flexible printed circuit board FPC (Flexible Print Circuit) can resistance to bending because of itself characteristic, while assembling in assembly plant, major part all needs to do bending and processes, in some situation, FPC product even needs to have 90 ° of bendings of multiple tracks.As shown in Figure 1 to Figure 2, FPC product 1 top is dogleg section 11, and bottom is standing part 12, dogleg section 11 shape linearly originally before bending, need to by after 5 road bendings could time product design could meet assembling demand.
Assembly plant, because assembling space limits, makes FPC in the time of bending, and high especially for the requirement of angle, the especially situation to multiple tracks bending, as long as be wherein bent with together generation deviation, all can have a huge impact for last assembling.Make in FPC in manual bending, its bending shift ratio is quite high, and yield is even less than 60%.
Therefore, be necessary to provide a kind of new bending process tool to solve above problem.
[utility model content]
Main purpose of the present utility model is to provide a kind of tool that reduces angular deflection problem in multiple tracks bending.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of FPC multiple tracks bending process tool, comprise base, described base has and is opened in its positive profile guide groove, and described base front surface is mobilizable to be fixed with and somely FPC can be pressed into the pressing plate in described profile guide groove.
Preferably, described pressing plate rear portion schedules the front of described base by hinges fixing.
Preferably, described pressing plate front portion has the compressing tablet that can embed in described profile guide groove.
In some embodiments, described compressing tablet has the oblique angle of corresponding bending position.
Preferably, described compressing tablet front is projected on described pressing plate front, and the described compressing tablet back side is recessed in the described pressing plate back side.
In some embodiments, described pressing plate is provided with the first magnet, and when the corresponding described compressing tablet of described base front surface is incorporated into profile guide groove, the position of the first magnet is provided with the second magnet.
Preferably, described pressing plate front is also provided with the draw-in groove for accommodating FPC product standing part.
Compared with prior art, the beneficial effect of the utility model FPC multiple tracks bending process tool is:
1, profile guide groove is according to the shape of product design after bending, and after per pass bending, other parts of FPC can continue to lay along profile guide groove, and therefore the angular deflection of per pass bending is all in error allowed band.
2, some pressing plates play to distribute and compress the FPC effect of dogleg section, ensure that the distance between every twice bending position is accurate, adopt the mode of attraction can keep the clamped condition of pressing plate and base, make workman can free hand to carry out other operations.
3, protrude from pressing plate positive and can extrude half-angle when the FPC bending with the compressing tablet at oblique angle, the compressing tablet back side is recessed can attenuate compressing tablet thickness, reduces knuckle position and take the length of FPC, makes the range error of FPC end in tolerance interval.
4, draw-in groove is used for the standing part of accommodating FPC, facilitates the spacing of first bending.

[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 3, Figure 4, the utility model is a kind of FPC multiple tracks bending process tool, it comprises several pressing plates 22 that front is provided with the base 21 of profile guide groove 211 and two draw-in grooves 213 and is installed on base 21 fronts by hinge 23, pressing plate 22 comprises the first pressing plate 22a, the second pressing plate 22b, the 3rd pressing plate 22c, the 4th pressing plate 22d and the 5th pressing plate 22e that distribute successively around profile guide groove 211 extension paths, and each pressing plate 22 has similar structure.Profile guide groove 211 can limit the laying direction of PFC product 1 bending part 11, controls the angular deflection of per pass bending, and pressing plate 22 is responsible for being pressed in profile guide groove 211.
With reference to figure 3, Fig. 4, each pressing plate 22 front ends have a compressing tablet 221 that can embed profile guide groove 211.Pressing plate 22 can by hinge 23 change external-open and in the state that closes, the compressing tablet 221 on the second pressing plate 22b, the 3rd pressing plate 22c, the 4th pressing plate 22d, the 5th pressing plate 22e has the oblique angle 2211 of 45 °, FPC product 1 part can be carried out to 90 ° of bendings.
With reference to figure 5, the front of compressing tablet 221 protrudes from pressing plate 22 fronts, and the reverse side of compressing tablet 221 is recessed in pressing plate 22 back sides.Compressing tablet 221 thinner thicknesses, minimizing knuckle position takies the length of FPC product 1, makes the range error of FPC end in tolerance interval.Compressing tablet 221 can be pressed into the part of FPC product 1 in profile guide groove 211.In the middle of pressing plate 22, be provided with the first magnet 222, the correspondence position of base 21 is provided with the second magnet 212.While closing in pressing plate 22, the first magnet 222 and the second magnet 212 are attracted each other, and make after closing in each pressing plate 22 and FPC product 1 bending part 11 can be limited in profile guide groove 211 more securely, make workman can free hand to down bending together.
Before bending, making the whole external-opens of pressing plate 22 is Fig. 3 state, and the FPC product 1 of Fig. 1 state is placed on base 21, makes its standing part 12 be placed in draw-in groove 213, and the root of dogleg section 11 is placed in profile guide groove 211, and the initial position of FPC product 1 can be determined.Then in the first pressing plate 22a, close, FPC product 1 part is pressed in profile guide groove 211 and carries out 180 ° of bendings in the first knuckle 11a position, FPC product 1 bending back segment is walked around from compressing tablet 221 back sides; Manual by dogleg section 11 remainder tensions, then in the second pressing plate 22b, close, continue one section after FPC product 1 first knuckle 11a be pressed in profile guide groove 211 and carry out 90 ° of bendings in the second knuckle 11b position, FPC product 1 bending back segment is walked around from compressing tablet 221 back sides again; According to same principle bending the 3rd knuckle 11c, four fold angle 11d and the 5th knuckle 11e, finally obtain the FPC product 1 of Fig. 2 state.
Rely on this tool to carry out after bending process, FPC product yield brings up to 95%, compares originally pure manual bending and is significantly improved.
Above-described is only execution modes more of the present utility model.For the person of ordinary skill of the art, not departing under the prerequisite of the utility model creation design, can also make some distortion and improvement, these all belong to protection range of the present utility model.
