Embodiment 1
[0027] Such as figure 1 As shown, a positioning fixture for flexible circuit board assembly is composed of a layer of bottom plate 1, a layer of thin steel sheet 2 on the bottom plate 1, a layer of lock pressing plate 4 on the thin steel sheet 2, and a layer of lock pressing plate 4. One layer of FPC carrier board 5, vertically penetrates the thin steel sheet 2, the product positioning pin 6 of the lock pressing plate 4 and the FPC carrier board 5 and the carrier board positioning pin 7, vertically penetrates the locking pressing plate 4 and the thin steel sheet 2 downwards and The above-mentioned two-layer board and two kinds of positioning pins are fastened to the screws 8 on the bottom plate 1.
[0028] The processing requirements of each component are as follows:
[0029] The upper surface of the bottom plate 1 is processed with the counterbore 9 for the product positioning pin, the counterbore 10 for the positioning pin of the carrier plate, and the assembly screw hole 1...
Embodiment 2
[0049] Such as Figure 5 As shown, a positioning fixture for assembly of a flexible circuit board (FPC) according to the present invention consists of a base plate 1, a lower thin steel sheet 2 (1), a middle transition plate 3, and an upper thin steel sheet 2 ( 2), one layer of locking plate 4, one layer of FPC carrier board 5, vertically penetrate the five-layer board except the bottom plate 1 and insert the product positioning pin 6 of the bottom plate 1 and the carrier plate positioning pin 7, vertically penetrate two layers of thin steel sheets , the intermediate transition plate 3 and the lock pressing plate 4 and the screws 8 fastening the above-mentioned four-layer plate and two kinds of positioning pins on the bottom plate 1.
[0050] The processing requirements of each component are as follows:
[0051] The lower thin steel sheet 2 (1), the upper thin steel sheet 2 (2), the intermediate transition plate 3, the lock plate 4, and the FPC carrier plate 5 process holes t...
