Examples

As shown in fig. 3, the positioning is performed by using the nip, when the FPC board is bent, the position of the nip needs to be observed, and the nip is carefully checked and attached to the edge of the FPC board, the nip is not protruded, so that the worker needs to pay attention to observe the nip, and the nip can only be used as a reference line, and cannot perform limiting, the positioning is deviated, and the worker is difficult to perceive the nip, so that a large problem exists.

The present embodiment provides a FPC bending positioning device, please refer to fig. 1-2, which includes an iron frame 1 and an FPC board 2, wherein a positioning protrusion 3 is integrally formed on the iron frame 1, the positioning protrusion 3 is located at a bending position of the FPC board 2, that is, the positioning protrusion 3 protrudes out of the iron frame 1, and the bending position of the FPC board 2 is positioned by the positioning protrusion 3, so as to improve the positioning accuracy of the FPC board 2. And when the preparation, can design the mould, make location arch 3 and chase 1 integrated into one piece to promote the positioning accuracy of location arch 3 greatly, fundamentally solves the problem that the location rate of accuracy is low. And combine casing empty space and FPC board 2's body thickness to carry out the comprehensive consideration, can make protruding 3 height of location be more than or equal to 0.15mm (FPC board 2's body thickness generally is 0.13 +/-0.03 mm), protruding 3 height of location is higher than FPC board 2's thickness a little promptly, make the staff when operating, can clearly differentiate the position, promote the rate of accuracy of counterpointing, also can effectively promote staff's work efficiency simultaneously, reduce the human cost of production.

As shown in fig. 4, the tolerance of the bending of the existing bending manner of the FPC board 4 and the tolerance difference between the two positioning manner is illustrated only by way of example, wherein the specific positioning dimension in the drawing varies according to the selected product and is not used for limiting the position of the positioning post, and the comparison in the drawing shows that the tolerance difference between the two positioning manner is ± 0..

And in the assembling process, in order to promote FPC board 2 and the protruding 3 cooperation effect of location, further promote the location rate of accuracy, can reserve the location breach with the protruding 3 matched with of location at the edge of FPC board 2, and the location breach and the FPC board 2 department of contact shape looks adaptation of department with FPC board 2, and the department of location generally has edges and corners, if establish according to edges and corners, then increase the friction of the two easily, perhaps make FPC board 2 be by the fish tail at the in-process of bending easily, to this, can set up the protruding 3 location as columniform reference column that sets up into, the cross section of reference column is circular promptly, and the location breach then sets up to be convex with reference column matched with, the circular arc is sunken towards the direction of keeping away from the reference column, when making the two contact, the contact surface is smooth and level, can not cause the injury to FPC board 2.

By taking fig. 1 as an example, firstly press-fitting the FPC board 2 on the iron frame 1, then bending the FPC board 2, so that the gold finger thereon is bent to a designated position, and positioning is performed through the positioning column during bending, so that the position of the worker can be clearly identified, a good limiting effect can be achieved during bending, and the accuracy of bending positioning is effectively improved.

During bending, although the positioning column can position the bent part, careful alignment is required during bending, as shown in fig. 5-7, an auxiliary positioning assembly is further matched outside the iron frame 1, the auxiliary positioning assembly comprises a first positioning plate 5 and a second positioning plate 6 which are hinged, at least one clamping groove 7 for placing the iron frame 1 is formed in the first positioning plate 5, a bending groove 9 penetrating through the second positioning plate 6 and a limiting hole 8 for clamping the positioning column are formed in the second positioning plate 6, wherein the limiting hole 8 is communicated with the bending groove 9, the bending groove 9 is matched with the shape of the FPC board 2, after the second positioning plate 6 is covered with the first positioning plate 5, the positioning column is clamped into the limiting hole 8, so that a worker can see whether the positioning column is clamped into the positioning groove at one eye, if the positioning column is clamped into the positioning groove, it is explained that the first positioning plate 5 and the second positioning plate 6 are covered in place, the bending groove 9 is right opposite to the position of the FPC board 2 needing to be attached, the FPC board 2 is pulled at the moment, the FPC board 2 is bent in the bending groove 9, namely the FPC board 2 is bent, and the edge of the FPC board 2 is attached to the edge of the bending groove 9. Wherein the degree of depth of draw-in groove 7 equals with chase 1, FPC board 2 bends along bending groove 9, it is when bending to final position, the edge pastes with bending groove 9 edge mutually, thereby carry out better restriction to FPC board 2's bending position through reference column and bending groove 9, and when operating, the staff only need put into draw-in groove 7 with chase 1, then close second locating plate 6, and sweep whether a eye reference column card goes into spacing hole 8, judge whether skew takes place in the use for first locating plate 5 and second locating plate 6, then alright direct pulling FPC board 2, make it follow bending groove 9 card income, directly laminate on chase 1 can, in the whole operation process, the staff need not many places to see the location whether accurate, and be not afraid of staff tired hand trembles, avoided the appearance of artificial error, the accuracy of FPC board 2 location of bending has effectively been improved.

In addition, in order to facilitate the bending operation, the two sides of the clamping groove 7 are provided with the taking and placing groove 10 for the fingers to be clamped in, and when the iron frame 1 is put in or taken out, the fingers can be put in the taking and placing groove 10 to take out the iron frame 1.

In addition, more than one clamping groove 7 can be arranged on the first positioning plate 5, more than one bending groove 9 is arranged on the second positioning plate 6, as shown in fig. 7, as long as the clamping groove 7 can be correspondingly matched with the bending groove 9, the mode can be used for bending a plurality of FPC boards simultaneously, and the processing efficiency is effectively improved.

The above description is only for the preferred embodiment of the present invention, and the present invention is not limited thereto, the protection scope of the present invention is defined by the claims, and all structural changes equivalent to the contents of the description and drawings of the present invention should be included in the protection scope of the present invention.
