Abstract
The utility model relates to a kind of fluting red needle of PCB mould, and comprise the stiff end that is fixedly connected with PCB mould and the punching press end for punching press pcb board, the bottom surface of punching press end is die-cut, and die-cut of fluting red needle is stepped.The utility model is by being set to stepped by the die-cut face of fluting red needle, during fluting, die-cut of fluting red needle contacts with pcb board time sharing segment, increases the shearing force that notch bears, make the tangent plane of pcb board notch more smooth, and effectively avoid occurring Decrepitation Phenomena near pcb board notch.
Description
Technical field
The utility model relates to pcb board production equipment field, is specifically related to a kind of fluting red needle of PCB mould.
Background technology
PCB (Printed Circuit Board), printed circuit board, also known as printed circuit board (PCB), printed substrate, is the supporter of electronic devices and components.
In the production process of pcb board, in order to the needs such as assembling, electrical isolation of pcb board, need on pcb board, offer corresponding notch.Offer notch to slot mainly through the fluting red needle on PCB mould, normal conditions, the notch of pcb board is strip, and die-cut of the fluting red needle on PCB mould is the strip mated with notch.Existing fluting red needle, its die-cut is plane, and during die-cut pcb board, plane die-cut contacts with pcb board completely.When the notch that need offer is larger, die-cut area is also larger, and then reduces fluting red needle to the momentary shear power of pcb board, causes easily occurring Decrepitation Phenomena around PCB notch, thus whole pcb board is scrapped.
Utility model content
The purpose of this utility model overcomes shortcomings and deficiencies of the prior art, a kind of fluting red needle of PCB mould is provided, its die-cut face is set to stepped, grooving process is divided into multiple moment, and increase each fluting instantaneously slot red needle to the shearing force of pcb board, prevent explosion problem, make shear surface more smooth simultaneously.
The purpose of this utility model is achieved through the following technical solutions:
A fluting red needle for PCB mould, comprise the stiff end that is fixedly connected with PCB mould and the punching press end for punching press pcb board, the bottom surface of punching press end is die-cut, it is characterized in that: die-cut of fluting red needle for stepped.
As preferably, the area of each cascaded surface of described die-cut is 3mm × 0.5mm.
As preferably, the difference in height of adjacent two cascaded surfaces is between 0.1mm-0.5mm.
As preferably, the difference in height of adjacent two cascaded surfaces is 0.3mm.
The utility model comprises following advantage and beneficial effect compared to existing technology:
The utility model is by being set to stepped by the die-cut face of fluting red needle, during fluting, die-cut of fluting red needle contacts with pcb board time sharing segment, increases the shearing force that notch bears, make the tangent plane of pcb board notch more smooth, and effectively avoid occurring Decrepitation Phenomena near pcb board notch.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fluting red needle of PCB mould in embodiment;
Fig. 2 is the schematic diagram of the fluting red needle punching press pcb board of PCB mould in embodiment.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, 2, a kind of fluting red needle of PCB mould, comprises the stiff end 1 that is fixedly connected with PCB mould and the punching press end 2 for punching press pcb board.Stiff end is used for being fixedly connected with PCB mould.The bottom surface of described punching press end is die-cut face 21, when pcb board is slotted, fluting red needle treats fluting place with PCB mold movement to pcb board, fluting die-cut of red needle is waited to slot with pcb board and is contacted everywhere, under external force drives, the die-cut of fluting red needle treats that fluting place produces the large impact power of moment in the face of pcb board, thus on pcb board, goes out the notch consistent with red needle axial shape of slotting.Owing to slotting, die-cut of red needle is stepped, and form multiple cascaded surface 22, make the fluting of pcb board divide multiple period, multiple contact surface carries out.At one time, the contact area of fluting red needle and pcb board reduces greatly, thus strengthens fluting red needle to the momentary shear power of pcb board notch, makes the tangent plane of pcb board notch more smooth, and effectively avoids occurring Decrepitation Phenomena near pcb board notch.As preferably, the difference in height of adjacent two cascaded surfaces is between 0.1mm-0.5mm.In the present embodiment, the area of each cascaded surface of described die-cut is 3mm × 0.5mm, and the difference in height of adjacent two cascaded surfaces is 0.3mm, and the die-cut face of this fluting red needle comprises 4 cascaded surfaces, the uniformity of shearing force when keeping each cascaded surface to shear, and ensure that the efficiency of fluting.
The above embodiment only have expressed embodiment of the present utility model, and 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 all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
