Abstract
The utility model discloses a split type printed circuit board backing plate of driling, including central backing plate to reach two piece at least marginal backing plates that encircle central backing plate and assemble, be equipped with the locating hole on the edge backing plate, connect through connecting portion between center backing plate and marginal backing plate, connecting portion are including setting up a plurality of fixed orificess at central backing plate side, still including setting up fixed lug to the side of marginal backing plate, in can wedging the fixed orifices. The utility model discloses in, marginal backing plate can directly be changed continue the fixed position needle because of the loss is unable after to the locating hole, for the prior art who changes the monoblock backing plate, only trades the consumption that small size edge backing plate can reduce the backing plate by a wide margin, realizes reducing printed circuit board manufacturing cost's purpose.
Description
Technical field
The utility model relates to printed substrate production technical field, is specifically related to a kind of split type printed substrate drilling liner plate.
Background technology
Along with the develop rapidly of electronic technology, the use of electronic product is also more and more extensive, and printed substrate is the vitals of electronic product, and its production technology affects the quality of electronic product.In wiring board production process, need on sheet material, be drilled with the hole such as a large amount of location holes, heavy copper hole, in drilling operating, generally need to arrange below sheet material backing plate, to support sheet material, avoid sheet deformation and affect borehole accuracy.In addition, the edge of backing plate is generally also provided with some location holes, can be fixed on backing plate by the pilot pin penetrating sheet material by sheet material, avoids sheet material shake, skew in boring procedure.After drilling operating completes, then need to take off pilot pin.Long-Time Service, pilot pin will be worn and torn location hole, location hole aperture be increased and cannot stationary positioned pin, now then need to change backing plate.But now the centre loss of backing plate is less, directly change monoblock backing plate and will cause larger waste, especially in large-scale industrial production, a large amount of backing plate losses is by the reduction of limit production cost.
Utility model content
In view of this, low consumed drilling liner plate of circuit board can fall in the open one of the utility model.
The purpose of this utility model is achieved through the following technical solutions: a kind of split type printed substrate drilling liner plate, comprises center backing plate, and around the assembled at least two block edge backing plates of center backing plate; Described edge backing plate is provided with location hole; Described center backing plate is connected by connecting portion with between edge backing plate; Described connecting portion comprises the multiple fixing holes being arranged on center backing plate side, also comprise be arranged on backing plate side, edge, the fixing projection can wedged in fixing hole.
In the utility model, center backing plate and edge backing plate are separated from each other.Operationally, center backing plate can in boring procedure bracketing wiring board, prevent wiring board shake, distortion.Fixing hole is then all arranged at edge backing plate, after edge backing plate and center backing plate splice, can be fixed from edge to center backing plate.In boring procedure, pilot pin is then arranged in fixing hole.After location hole cannot continue stationary positioned pin because of loss, can directly change edge backing plate, relative to the prior art changing monoblock backing plate, only change the consumption that small size edge backing plate significantly can reduce backing plate, realize the object reducing printed substrate production cost.During splicing, only need will fix in projection wedging fixed block, get final product built-in edge backing plate and center backing plate, prevent it to be moved.
Further, described center backing plate is rectangle, and described edge backing plate quantity is two pieces, and is separately positioned on the two ends of center backing plate.
According to the time, in the process of printed substrate boring, only need to be fixed the two ends of sheet material, wiring board can be made stably to be attached on backing plate.Therefore, the both sides of the utility model Jin center backing plate arrange edge backing plate.Reduce the quantity of edge backing plate, be conducive to simplified structure.
Further, the stitching portion of described center backing plate and edge backing plate is provided with recessed cambered surface.
Recessed cambered surface has certain volume cushioning effect, avoids, because center backing plate, edge backing plate Yin Wendu produce harmomegathus and cause deformation, guaranteeing the precision of drilling operating.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is profile of the present utility model.
Embodiment
The utility model to be described in further detail below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that:
Embodiment 1
The present embodiment provides a kind of split type printed substrate drilling liner plate, as Fig. 1 and Fig. 2, comprises center backing plate 1, and is arranged on the two block edge backing plates 2 at backing plate two ends, center; Described edge backing plate is provided with location hole 3; Described center backing plate is connected by connecting portion with between edge backing plate; Described connecting portion comprises the multiple fixing holes 4 being arranged on center backing plate side, also comprise be arranged on backing plate side, edge, the fixing projection 5 can wedged in fixing hole.
Described center backing plate is rectangle.
The stitching portion of described center backing plate and edge backing plate is provided with recessed cambered surface 6.
Be more than wherein specific implementation of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection range of the present utility model.
