Description
Technical field
A kind of FPC die cutting die is the utility model is related to, particularly relates to a kind of structure for avoiding mould punching mistake.
Background technology
In the processing of FPC (FPC), an important factor for yields is in occupation of market competition all the time, how to carry
Efficiency is risen, the fraction defective for reducing product is to bring enterprise to bring more profits and the primary condition won the market.Influence FPC yields
Factor generally include two aspect, one be due to design when consider not comprehensively, cause product directly scrap.It is another
Individual is either cover layer or finished goods in production procedure, and due to the carelessness of operator, in punching, often occurring will
The line of production puts back or rotated 180 degree, causes scrapping for product, so as to cause product can not consign to client on time, makes simultaneously
Into artificial and raw material waste, cause the increase of cost.
Either in the processing of flexible circuitry cover layer or the final punching of circuit product, only two kinds of phenomenons can occur
Mistake is punched:First, by cover layer(Without circuit)Rotate 180 degree;Second, dual platen positive and negative overturns.Due to dredging for operating personnel
Suddenly, the product punching of punching can usually be scrapped, especially cover layer is due to no circuit, it is difficult to find product punching instead, to treat
When being applied to next procedure, just find it has been the state that can not be returned in evening.
In view of this, product punching occurs when product is easily overturned and rotated in punching for existing FPC by the design people
Cut mistake situation and deep design, and actively research improvement have a fling at and develop and design the utility model.
Utility model content
The purpose of this utility model is to overcome the shortcomings of the prior art and providing one kind can avoid product from being punched
Link, which produces, scraps, so as to improve the structure for avoiding mould punching mistake of product yield.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of structure for avoiding mould punching mistake, it includes die cutting die and flexible PCB, and die cutting die is provided with
Multiple shop bolts for being higher by die cutting die plane, it is mistake proofing pin at least to have one in the shop bolt, mistake proofing pin
Size be more than or less than other shop bolts, set on the flexible PCB and each shop bolt of die cutting die and anti-
Wrong pin location and size multiple positioning holes correspondingly, have in multiple positioning holes corresponding with mistake proofing pin location and size
Mistake proofing positioning hole.
Covered with the cover layer is provided with to be corresponded with each positioning hole of flexible PCB on the flexible PCB
Multiple mating holes, there is mistake proofing mating holes corresponding with mistake proofing position of positioning hole and size in multiple mating holes.
The shop bolt, positioning hole and mating holes are respectively four, wherein mistake proofing pin, mistake proofing positioning hole and anti-mispairing
It is respectively one to close hole.
After said structure, the utility model passes through the rational design to shop bolt and positioning hole, so that it may avoid by
Random change in punching direction, the product rejection of product punching link is caused, so as to improve the yield of product.Pass through actual life
The performance tests of producing line, the utility model are carried out rationally in the case where die cutting die is almost unchanged to the local of die cutting die
Change, the generation of mistake can be entirely prevented, so as to improve the yield of product, the utility model is simple in construction, positive effect, and
Any expense will not be increased.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model die cutting die.
Fig. 2 is the structural representation of the utility model flexible PCB.
Fig. 3 is the structural representation of the utility model cover layer.
Embodiment
In order to which the technical solution of the utility model is explained further, the utility model is entered below by specific embodiment
Row elaborates.
As shown in Figure 1 and Figure 2, the utility model discloses a kind of structure for avoiding mould punching mistake, and it includes blanking die
Tool 1 and flexible PCB 2, die cutting die 1 are provided with multiple shop bolts 11 for being higher by die cutting die plane, the shop bolt
It is mistake proofing pin 111 at least to have one in 11, and the size of mistake proofing pin 111 is more than or less than other shop bolts 11, institute
It is one-to-one with each shop bolt 11 of die cutting die 1 and the position of mistake proofing pin 111 and size to state setting on flexible PCB 2
Multiple positioning holes 21, there is mistake proofing positioning hole 211 corresponding with the position of mistake proofing pin 111 and size in multiple positioning holes 21.
Wherein, there can be two states during 2 punching press of flexible PCB, a kind of is the semi-finished product of no circuit, and another kind is
Finished goods that is etched or printing circuit, that is to say, that flexible PCB 2 can first be punched into shape be etched again or
Printed wire, it also can first complete circuit and be punched out again, in order to prevent flexible PCB from aoxidizing, not etch or printed wire
One layer of cover layer 3 can be covered on flexible PCB 2, cover layer 3 is provided with to be corresponded with each positioning hole 21 of flexible PCB 2
Multiple mating holes 31, there is mistake proofing mating holes corresponding with the position of mistake proofing positioning hole 211 and size in multiple mating holes 31
311。
As shown in Figure 1 to Figure 3, the utility model is in the design of conventional die cutting die, by original four in the present embodiment
The mistake proofing pin that the enlarged diameter of one of shop bolt 11 of individual same a diameter of 2.0cm shop bolt 11 is 2.5cm
111, and the height of each shop bolt 11 and mistake proofing pin 211 is higher by 2.5mm according to the plane of die cutting die 1 and installed.Will
The positioning hole of flexible PCB 2(There is the mating holes 31 for also including cover layer 3 of cover layer 3)With the mistake proofing pin of die cutting die 1
111 are correspondingly arranged, and are so punched direction and any change occurs, flexible PCB 2 can not be inserted in mistake proofing pin 111, can keep away
Flexible PCB 2 is punched the generation of mistake when exempting from reverse flexible PCB 3 and rotation, improves the yield of product.
The flexible PCB 2 that needs are punched is on positioning hole machine according to the shop bolt 11 and mistake proofing pin of die cutting die 1
The positioning hole 21 and mistake proofing positioning hole 211 of nail 111, and the mating holes 31 of cover layer 3 uses numerical control drilling according to aperture and status requirement
Machine, and be covered on flexible PCB 2, it would be desirable to which the flexible PCB 2 of punching is according to the positioning hole preset
21, it is necessary to four positioning holes 21 of product are completely nested in shop bolt 11, after confirmation it is smooth be inserted in after can just be punched out
Operation.
The utility model passes through the rational design to shop bolt 11 and positioning hole 21, so that it may avoids due to punching direction
Arbitrarily change, the product rejection of product punching link is caused, so as to improve the yield of product.Examined by the operation of actual production line
Test, the utility model is rationally changed in the case where die cutting die is almost unchanged to the part of die cutting die, can be complete
Prevent mistake generation, randomly select 200 item numbers, each 5 batches, verified, error case be 0, by it is original this
Error rate is directly reduced to 0% from 10%, and method is simple and effective, and so as to improve the yield of product, the utility model is simple in construction,
Positive effect, and any expense will not be increased.
Above-described embodiment and schema and non-limiting product form of the present utility model and style, any art
The appropriate change or modification that those of ordinary skill is done to it, all should be regarded as not departing from patent category of the present utility model.
