Description

A kind of general positioning base of flexible printed circuit board

Technical field

The utility model belongs to the positioner field, relates in particular to the general positioning base of the jigsaw location that is applied to flexible circuit board or little pcb board (printed substrate).

Background technology

Along with development of electronic technology, the particularly miniaturization of electronic product, the output of flexible PCB or flexible surface-mounted integrated circuit sharply increases, because the flexibility of flexible PCB (FPC) self, therefore, in surface mounting technology (SMT) the assembling processing procedure of flexible print circuit board (FPC), flexible print circuit board (FPC) must be fixed on the support plate and just can flow on production line, to guarantee efficient and the quality assurance in whole assembling, the course of processing.

It is positioning bases that flexible printed circuit board (FPC) is fixed on the crucial anchor clamps that need on the support plate to use, at present, because positioning base required precision height, specificity are strong, so in the new product development process, have influence on construction cycle and development cost.In addition, the processing of positioning base is processed with CNC, the processing cost height, and the cycle is long.Moreover existing positioning base and paste solder printing steel mesh are that two kinds of technologies are made, and mismatch error is big.The alignment pin of positioning base is a lathe in machining, and cost is high and can't reuse.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of general positioning base of flexible printed circuit board, and it can overcome above-mentioned defective, not only can be general, and the machining accuracy height, cost is low.

For solving the problems of the technologies described above, the utility model is achieved in that

A kind of general positioning base of flexible printed circuit board, comprise bedframe, base plate and align member, it also includes the location steel disc, described align member comprises first align member and second align member, described base plate is located at described bedframe below, and described bedframe, base plate and location steel disc are by described first align member location; Described second align member passes the location steel disc with the location product.

Preferably, above-mentioned location steel disc is two, is respectively location steel disc and following location steel disc, and described going up located the top that steel disc is located at described bedframe, and described location steel disc down is located at the below of described bedframe.

Preferably, above-mentioned bedframe below is provided with groove, and described location steel disc down is located in this groove.

Above-mentioned align member, it can be alignment pin, also can be locating piece or positioning boss etc., preferably, it is a reference column.

After adopting such scheme, during use, by first align member, energy steel disc and positioning base relative fixed, second align member passes the location steel disc, makes the align member relative fixed, reach the function of positioning base, support plate is placed on the bedframe, align member passes support plate and fixes product.Compare with commonly using, this is novel by changing the corresponding different product of steel disc, reaches general effect; In addition, the location steel disc is to process with the mode of laser cutting, machining accuracy height not only, high conformity, and the process-cycle lack, cost is low; Moreover second align member can reuse, thereby reduces whole cost; According to statistics, this machining accuracy by before ± 0.05mm rises to ± 0.02mm, its processing cost can reduce 2/3, the process-cycle can shorten 2/3.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Below each part of the present utility model is elaborated.

As shown in Figure 1, the general positioning base of a kind of flexible printed circuit board that the utility model embodiment provides, it comprises bedframe 1, base plate 2, location steel disc 3, align member 4, wherein:

Bedframe 1 is the structure of frame body intermediate blank around being; Be provided with location hole 11 around it; Cooperate shown in Fig. 4, the 4A, the below of bedframe 1 is provided with groove 12;

Align member 4 comprises first align member and second align member, and in the present embodiment, this align member is a reference column, wherein,

First reference column 41 is one group, and its quantity matches with bedframe 1 location hole all around;

Second reference column 42 is one group, and its quantity is by product itself decision, cooperates with

location hole

311 or 312 on the steel disc 3 of location.

Described base plate 2 is a flat board, and the bottom surface that also is provided with location hole 21, the second reference columns 42 around it is located on the base plate 2, and therefore, it plays a supportive role to second reference column 42;

Location steel disc 3 is two, is respectively location steel disc 31 and following location steel disc 32, and this locatees steel disc, is according to different products, which is provided with different location hole 311,312, in addition, also is provided with the location hole 312,322 that cooperates with first reference column 41 around it; In when assembling, on locate the top that steel disc 31 is located at bedframe 1, following location steel disc 32 is located at the below of bedframe 1.
