Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 6, the FPC3 has a certain thickness, and has

interfaces

3a and 3b at its two ends. Since the FPC3 has a certain thickness, when it is manually bent, the circuit inside the FPC3 is easily damaged, and the bending efficiency is low.

Therefore, to this FPC300, the embodiment of the utility model provides a FPC tool of bending is proposed.

As shown in fig. 1-3, the FPC bending jig includes a jig upper plate 1 and a jig lower plate 2 that forms a mold closing relationship with the jig upper plate 1. The lower jig plate 2 has a carrying station 2a, and the left and right sides of the carrying station 2a are respectively provided with a bending lower station 21 and a bending lower station 22. Limiting strips 23 are respectively arranged on the front side and the rear side of the bearing station 2a, mounting grooves are formed between the two limiting strips 23 and the bearing station 2a, a body of the FPC3 to be bent is clamped in the mounting grooves, and parts to be bent at the two ends of the FPC3 are respectively suspended above the bending lower station 21 and the bending lower station 22. The jig upper plate 1 is provided with a pressing station 1a corresponding to the bearing station 2a, the left side and the right side of the pressing station 1a are respectively provided with a bending upper station 11 and a bending upper station 12 which are matched with the bending lower station 21 and the bending lower station 22, and the front side and the rear side of the pressing station 1a are respectively provided with an avoiding groove 1b for avoiding a limiting strip 23. Meanwhile, the surfaces of the bending upper station 11 and the bending upper station 12 are respectively recessed on the accommodating groove 11a and the accommodating groove 12a to avoid the

interfaces

3a and 3b at the two ends of the FPC 3.

During bending, the bending upper station 11 and the bending upper station 11 of the jig upper plate 1 respectively press the parts to be bent at the left end and the right end of the FPC3 into the bending lower station 21 and the bending lower station 22, so that the FPC3 is bent.

Compared with the prior art, the utility model provides a FPC tool of bending can realize carrying out the shaping of once bending to FPC3 that has certain thickness, and is efficient. And, tool hypoplastron 2 has the mounting groove, can play spacing fixed action to FPC3 in the bending process, avoids FPC3 aversion or deflect, ensures that FPC3 keeps the horizontality when bending, and then avoids damaging the problem of FPC3 internal line when bending.

Alternatively, as shown in fig. 2, in the present embodiment, a positioning groove 21a and a positioning groove 22a are respectively provided on the bending lower station 21 and the bending lower station 22, and the portions to be bent at the left and right ends of the FPC3 are respectively clamped in the

positioning grooves

21a and 22 a. The positioning grooves 21a and the positioning grooves 22a can play a role in positioning and guiding the to-be-bent part of the FPC3, so that the to-be-bent part can be bent and molded along the positioning grooves, and the bending yield is guaranteed.

Further, as shown in fig. 2-5, the positioning groove 21a extends upward to form a guide opening, and the bending upper station 11 extends downward to form a guide protrusion. From this, the pressfitting of tool upper plate 1 plays the effect of direction in advance for station 11 can align with the station 21 down of bending accurately on bending, provides basic guarantee for subsequent accurate bending.

Still further, the corner on the inlet side of the guide opening is chamfered to form an inclined surface 21b inclined outward. While the corner of the end of the guide projection is chamfered to form an inwardly inclined surface 11 b. Therefore, the caliber of the inlet side of the guide opening is increased, the caliber of the end part of the guide protrusion is reduced, and the upper station and the lower station are convenient to bend and insert.

Similarly, the positioning slot 22a also extends upward to form a guide opening, and correspondingly, the bending upper station 12 extends downward to form a guide projection. Moreover, the inlet side of the guide opening of the positioning groove 22a is chamfered to form an outward inclined surface 22b, and the end of the guide projection of the bending upper station 12 is chamfered to form an inward inclined surface 12b, thereby realizing the alignment and insertion of the bending upper station 12 and the bending lower station 22.

During bending, the bending upper station 11 presses the part to be bent downwards, so that the part to be bent is pressed between the upper bending pressing surface 11c and the lower bending pressing surface 21 c.

Alternatively, the connecting portion of the upper bending pressing surface 11c and the surface of the upper bending station 11 is rounded to form an arc-shaped contact surface 11 d. The connecting part of the lower bending pressing surface 21c and the surface of the bearing station 2a is rounded to form an arc-shaped contact surface 21 d. During bending, the upper bending station 11 applies pressure to the FPC through the arc-shaped contact surface 11d, and the FPC3 gradually deforms along the arc-shaped contact surface 21d of the lower bending station 21 to form a bending portion. The contact part between the upper bending station 11 and the lower bending station 21 and the PFC bending part is rounded, so that good bending is facilitated.

The above is only the preferred embodiment of the present invention, not used in the present invention, and any slight modifications, equivalent replacements and improvements made by the technical entity of the present invention to the above embodiments should be included in the protection scope of the technical solution of the present invention.
