Specific embodiment
It please refers to shown in Fig. 1-4, a kind of lid becket jig of biological fingerprint class FPC, including jig unit 1, feature
It is, jig unit 1 includes a bottom plate 3 and a limit plate 2, and the bottom plate 3 further includes that several elements keep away a hole 4, described
3 surface of bottom plate, which is equipped with, keeps away 4 position of a hole with element and the corresponding FPC of quantity keeps away a hole 6,3 upper surface of bottom plate and the limit
Position 2 lower surface of plate is bonded the FPC bit-avoiding slot to be formed for placing FPC and becket, and the thickness that the element keeps away a hole 4 is not less than
The thickness of element, the thickness of the FPC bit-avoiding slot are greater than the thickness of FPC, are stacked with fixation between the jig unit 1.
Compared to existing technology, the utility model bottom plate 3, which is provided with element, to be kept away a hole 4 FPC is enabled to lie against bottom plate
3, form FPC bit-avoiding slot using bottom plate 3 and limit plate 2, can ensure relative positional accuracy between becket and FPC ±
Within 0.075mm, the position precision between becket and FPC is fully met, while being stacked with fixation between jig unit 1,
Meet the production requirement of heterogenous small lot and processing cost is low.
Specifically: the FPC keeps away on the inside of a hole 6 fixed point 7 for being equipped with several evaginations.
Using the above scheme, it should be made by compact design by the way that the size of fixed point is arranged, to ensure becket and FPC
Between Anawgy accuracy.
Specifically: the bottom plate 3 is additionally provided with air hole 5.
Using the above scheme, by setting air hole 5 in order to the propagation of the heat when solidifying, so that in entire jig
The temperature in portion is consistent, to guarantee the solidification effect of product.
Specifically: the lower end of becket is fixed in FPC bit-avoiding slot by the FPC bit-avoiding slot, and upper end extends to FPC and keeps away position
Outside slot, and extends thickness and be no more than 0.5mm.
Using the above scheme, the size is also logical as hot-air when solidifying in addition to the pressing gap tolerances for cover board
Road uses, excessive temperature differentials when avoiding solidifying inside and outside fixture.
Specifically: the side of the bottom plate and the limit plate is equipped with pin hole and pin keeps away a hole, pin hole interpolation
It is connected to pin, hole is kept away by pin between jig unit and is fixedly connected with bayonet fittings.
Using the above scheme, jig unit can be made to design by hole location, can covered by pin between muti-piece jig
It is stacked after becket.
Specifically: the jig unit rotates the setting of 180 degree staggered alignment between adjacent jig unit, and between jig unit
FPC bit-avoiding slot be mutually aligned.
Using the above scheme, it avoids that pressurize fixture can not be used in process below.
The utility model is further described below by specific embodiment.
Using when the jig first will the FPC of lid becket be placed on jig, be arranged when FPC is put by bottom plate 3
Element keeps away a hole 4 and carries out keeping away position to the other elements on FPC, and FPC is enabled to lie against bottom plate 3, at this moment further through FPC bit-avoiding slot
FPC is fixed, then the point structure glue location hole 10 by being arranged in jig unit 1 carries out the positioning of point structure glue, it is then right
FPC carries out point structure glue, can choose whether a silver paste according to the actual situation later, then becket is placed on FPC, at this moment,
It can ensure that the relative positional accuracy between becket and FPC within ± 0.075mm, keeps away position by FPC by FPC bit-avoiding slot
It is equipped with the fixed point 7 of several evaginations on the inside of hole 6, can ensure the Anawgy accuracy between becket and FPC, jig unit passes through
The design of pin hole location, can be stacked between muti-piece jig by pin, finally be solidified, and when solidification passes through air hole 5
