Abstract
The utility model relates to one kind to be related to flexible circuit board production field, it is specifically related to a kind of flexible circuit board punching cutter, cover board including cutting die bottom plate and right above cutting die bottom plate, several stamping knives are carved on the cutting die bottom plate, the cutting die bottom plate has multiple shop bolts made of engraving together with stamping knife, there are several relief holes, and each shop bolt can be corresponding with a relief hole on the cover board, the shop bolt tolerance to solve the problems, such as existing punching cutter is larger.
Description
Technical field
The utility model relates to flexible circuit board production fields, are specifically related to a kind of flexible circuit board punching cutter.
Background technique
Flexible circuit board is widely used in the production of the consumer electronics such as electronics field, especially mobile phone, laptop
On product.Demand with market to the frivolous miniaturization of this electronic product is prominent, and the route laid on wiring board is also closer and closer
Collection, line width are also smaller and smaller.
It is all shape to be punched by the way of punching molding, and contraposition when being punched all is in existing flexible circuit board
It is realized by positioning pin, the contraposition pin on existing punching cutter is all spring pin, pin position and sleeve because needing
Telescopic movable is wanted to work, so the structure and working principle of spring pin have led to it, and there are unavoidable essences there are gap
Tolerance is spent, furthermore spring pin is all to be fixed on punching cutter using the modes such as be spirally connected, therefore this spring pin is fixed on
There is also tolerance, the minimal tolerance that the presence of both tolerances results in existing pin positioning all exists punching cutter itself
0.1mm or so, therefore when being punched out to wiring board, the tolerance of flexible circuit board shape back gauge pad is then on the left side ± 0.2mm
The right side, therefore can not be applied in flexible circuit board punching of the precision requirement tolerance no more than 0.1mm.
Utility model content
The utility model is intended to provide a kind of flexible circuit board punching cutter, to solve the shop bolt of existing punching cutter
The larger problem of tolerance.
Concrete scheme is as follows:
A kind of flexible circuit board punching cutter, the cover board including cutting die bottom plate and right above cutting die bottom plate, the knife
It is carved with several stamping knives on baffle plate, there are multiple shop bolt made of engraving, institutes together with stamping knife on the cutting die bottom plate
Stating has several relief holes on cover board, and each shop bolt can be corresponding with a relief hole.
Further, the shop bolt includes columned pin body, and the top of the pin body is and the pin
Follow closely the pointed structures of ontology coaxial arrangement.
Further, the top of the pointed structures at the top of the pin body is ball head structure.
Further, multiple shop bolts on the cutting die bottom plate are asymmetric setting.
Flexible circuit board punching cutter provided by the utility model has the advantage that practical compared with prior art
Shop bolt on the flexible circuit board punching cutter of novel offer is formed directly on cutting die bottom plate and is to carve together with stamping knife
Made of quarter, therefore the tolerance between shop bolt and stamping knife is avoided, while also avoiding the tolerance of spring pin itself, made
The shop bolt can achieve the tolerance of the mold knife edge and pin no more than 0.05mm, to accomplish flexible circuit board shape side
Tolerance apart from pad is within ± 0.1mm.
Detailed description of the invention
Fig. 1 shows the schematic diagram of flexible circuit board punching cutter.
Fig. 2 shows the schematic diagrames for seeing shop bolt.
Specific embodiment
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses
A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in Figure 1, the utility model provides a kind of flexible circuit board punching cutter, the flexible circuit board punching cutter
Include cutting die bottom plate 10 and and the cover board 20 right above cutting die bottom plate 10, wherein be carved on the cutting die bottom plate 10
Several stamping knives 100, shop bolt 110 made of all there is multiple and stamping knife 100 to carve together for each 100 side of stamping knife are described
There are several relief holes 200, and each shop bolt 110 can be corresponding with a relief hole 200 on cover board 20, so that rushing
Shop bolt 110 is formed when cutting and is stepped down.
Made of passing through engraving together as shop bolt 110 and stamping knife 100, between shop bolt 110 and stamping knife
Spacing be to secure, tolerance is not present, therefore the tolerance between shop bolt 110 and the knife edge of stamping knife 100 is only dependent upon carving
Quarter machine oneself precision, therefore the allowance control between the knife edge knife edge and shop bolt 110 of stamping knife 100 can be not more than it
0.05mm, and relative to existing by the way of spring pin, the presence of spring pin own tolerances is also avoided, so as to
To accomplish the tolerance of flexible circuit board shape back gauge pad within ± 0.1mm.
With reference to Fig. 2, in the present embodiment, the shop bolt 110 includes columned pin body 112, the pin
The top of ontology 112 is the pointed structures 114 being coaxially disposed with the pin body 112, and the pointed structures 114 at top can be in order to
Location hole in flexible circuit board, and convenient for the contraposition between the location hole on shop bolt 110 and flexible circuit board.Its
In, the height of pointed structures 114 is typically in the range of between the 1/6~1/5 of entire 112 height of pin body.
Preferably, the top of the pointed structures 114 at 112 top of pin body is ball head structure 116, to prevent it will
Flexible circuit board scratches.
In the present embodiment, preferably, multiple shop bolts 110 on the cutting die bottom plate 10 are asymmetric setting.By
In shop bolt 110 by the way of asymmetric setting, the location hole in opposite flexible circuit board is also asymmetric setting, because
The shop bolt 110 of this asymmetric setting can also play the role of fool proof.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered
This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details
On the utility model can be made a variety of changes, be the protection scope of the utility model.
