Abstract

The utility model discloses a fixation device for a PCB (printed circuit board). The fixation device comprises a rectangular outer frame and rectangular inner frames, wherein a fixing clamp is arranged on the frame body of the rectangular outer frame; the centres of one side and the opposite side of the inner side of the rectangular outer frame are connected by a rotary shaft; the rectangular inner frames are fixedly connected to the rotary shaft along the radial direction of the rotary shaft; the rectangular inner frames are uniformly distributed around the rotary shaft; fixing clamping buckles are arranged on the four corners of each rectangular inner frame; and the four corners of the PCB are fixed by the fixing clamping buckles. Via the design aforementioned, simultaneous machining for the front surface and the back surface of the PCB can be realized after the PCB is fixed, thus increasing production efficiency.

Description

A kind of pcb board fixture

Technical field

The utility model relates to PCB production equipment field, is specifically related to a kind of pcb board fixture.

Background technology

In electronics processing and manufacturing industry, dissimilar process flow for assembling is arranged, for double-side technology (positive and negative two sides processing procedure), the obverse and reverse of PCB plate all needs soldering part or carries out surface treatment.Positioner now only can position the positive latter's reverse side of PCB plate, after positive production and processing completes, then reverse side is carried out to production and processing, namely needs to change twice line production, makes operation rate low, and production efficiency is low, and cost is high.Simultaneously, the finished product output cycle is long, easily causes the oxidation of substrate pads point, causes the via pad failure welding, particularly on the impact of OSP technique.Therefore, how to change the process of PCB plate, improving production efficiency, reduce production costs, and in the field of business is also the task of top priority.

The utility model content

The purpose of this utility model is to overcome the defect existed in prior art, and a kind of reasonable in design, the simple in structure and pcb board fixture that can greatly enhance productivity is provided.

For achieving the above object, the technical solution of the utility model has been to provide a kind of pcb board fixture, comprise rectangle housing and rectangle inside casing, rectangle housing framework is provided with geometrical clamp, the center on the inboard symmetrical both sides of rectangle housing is connected by a rotation axis, radially be fixedly connected with a plurality of rectangle inside casings along rotation axis on rotation axis, a plurality of rectangle inside casings moving axis that rotates is uniformly distributed, and four jiaos of each rectangle inside casings are provided with fixedly buckle of pcb board.

As preferably, described rectangle inside casing is two.

As preferably, described geometrical clamp is two, is separately positioned on the center of two adjacent sides on limit, rotation axis place.

Advantage of the present utility model and beneficial effect are: by above design, can realize after fixing PCB plate, can realize processing to the positive and negative of pcb board by the rotation rotation axis simultaneously, enhance productivity; Described rectangle inside casing is set to two, and rectangle inside casing surface angle is 180 degree, is the better simply embodiment of the design, and production cost is low, and working (machining) efficiency is high; Described geometrical clamp is set to two, is separately positioned on two adjacent side centers on limit, rotation axis place, can reach like this and use less geometrical clamp to realize fixed effect preferably.

In figure: 1, rectangle housing; 2, rectangle inside casing; 3, rotation axis; 4, geometrical clamp; 5, the fixing buckle of pcb board; 6, pcb board.

Embodiment

Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection range of the present utility model with this.

As depicted in figs. 1 and 2, a kind of pcb board fixture, comprise rectangle housing 1 and rectangle inside casing 2, rectangle housing 1 framework is provided with geometrical clamp 4, the center on rectangle housing 1 inboard symmetrical both sides is connected by a rotation axis 3, on rotation axis 3, along rotation axis 3, radially is fixedly connected with a plurality of rectangle inside casings 2, and a plurality of rectangle inside casings 2 moving axis 3 that rotates is uniformly distributed, 2 four jiaos of each rectangle inside casings are provided with fixedly buckle 5 of pcb board, pcb board fixedly buckle 5 by pcb board 6 Corner Strappeds.

As preferably, described rectangle inside casing 2 is two, and the surperficial angle of rectangle inside casing 2 is 180 degree.

As preferably, described geometrical clamp 4 is two, is separately positioned on the center of two adjacent sides on rotation axis 3 limits, place.

In actual use procedure, two pcb boards 6 are fixed on two inside casings 2 by fixing buckle 5, wherein a pcb board 6 faces up, an other reverse side upward, rotation rotation axis 3, make a pcb board 6 face up, and an other reverse side upward, with two geometrical clamps 4, that two inside casings 2 are fixing, then respectively the obverse and reverse while face of two pcb boards 6 is processed; To unclamp with geometrical clamp 4, rotation rotation axis 3 one hundred eight ten degree, re-use two geometrical clamps 4 two inside casings 2 are fixing, and the at this moment positive and negative of two pcb boards 6 transposition, processed two unprocessed positive and negatives of pcb board.Unclamp fixedly buckle 5 two pcb boards 6 are taken out, complete operation.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
