Abstract
The utility model provides a kind of automatic waste discharge cutting die of FPC double faced adhesive tapes, including cutting die, the knife face of the cutting die has the raised knife edge, and the knife edge has the chip removal groove connected with the knife back, the knife face of the cutting die also has the buffering adhesive for buffering, and the knife back of the cutting die is concave surface；The knife edge of cutting die only cuts off the viscose glue in top layer release liners and intermediate layer, and bottom release liners are not cut off；Cut-off waste material can enter in chip removal groove, and whenever cutting die is punched once, new waste material can head into old waste material inside chip removal groove, when garbage collection in chip removal groove is full, unnecessary waste material excludes directly at the knife back, and without manual cleaning, the processing efficiency of FPC double faced adhesive tapes improves.
Description
Technical field
A kind of cutting cutter die is the utility model is related to, more particularly to a kind of automatic waste discharge cutting die of FPC double faced adhesive tapes.
Background technology
FPC double faced adhesive tapes 2, as shown in Fig. 1 panel A, including bottom release liners 21, the viscose glue 22 in intermediate layer and top layer from
Type paper 23, for a kind of particular adhesive being pasted and fixed on FPC flexible circuit boards in backlight, due to FPC flexible circuit boards
Shape and irregular shape, so FPC double faced adhesive tapes will be cut out the FPC double faced adhesive tapes 2 on material strip 3 by cutting die before the use
Be cut into FPC flexible circuit board identical shapes, as shown in Fig. 1 component B.
In the prior art, the knife edge of the cutting cutter die of FPC double faced adhesive tapes has a closed chip pocket, and what is cut every time is useless
Material can be all collected into chip pocket, when the waste material in chip pocket accumulates to a certain degree, it is necessary to manually by chip pocket
Waste material picks out, and influences operating efficiency.
Utility model content
The purpose of this utility model is to provide a kind of automatic waste discharge cutting die of FPC double faced adhesive tapes, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve these goals, the utility model provides following technical scheme：
A kind of automatic waste discharge cutting die of FPC double faced adhesive tapes, including cutting die, the knife face of the cutting die have the raised knife edge, institute
Stating the knife edge has the chip removal groove connected with the knife back.
Further, the knife back of the cutting die is concave surface, and the knife face of the cutting die has the buffering adhesive for buffering.
The beneficial effects of the utility model are：The knife edge of cutting die cuts off the viscose glue in top layer release liners and intermediate layer, bottom
Release liners are not cut off；Cut-off waste material can enter in chip removal groove, and whenever cutting die is punched once, new waste material can give up old
Material is headed into inside chip removal groove, and when the garbage collection in chip removal groove is full, unnecessary waste material excludes directly at the knife back, without people
Work is cleared up, and the processing efficiency of FPC double faced adhesive tapes improves.
Brief description of the drawings
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Figure 1A is the cross-sectional view of FPC double faced adhesive tapes；
Figure 1B be FPC double faced adhesive tapes cut before with cut after contrast schematic diagram；
Fig. 2 is knife back structural representation of the present utility model；
Fig. 3 is cross-sectional view of the present utility model；
Fig. 4 is operating principle schematic diagram of the present utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing：
A kind of automatic waste discharge cutting die of FPC double faced adhesive tapes according to Fig. 1 and Fig. 3, including cutting die 1, the knife of the cutting die
Face has the raised knife edge 11, and the knife edge 11 has the chip removal groove 12 connected with the knife back, and the knife face of the cutting die also has
For the buffering adhesive 13 of buffering, the knife back of the cutting die is concave surface.
As shown in figure 4, cutting die will coordinate pressing machine to use, need to adjust the dynamics of pressing machine when in use so that cutting die
The knife edge 11 only the viscose glue 22 in top layer release liners 23 and intermediate layer is cut off, bottom release liners 21 are not cut off；Cut-off waste material
It can enter in chip removal groove 12, whenever cutting die is punched once, new waste material can head into old waste material inside chip removal groove 12, row
Consider to be worth doing garbage collection in groove 12 it is full when, unnecessary waste material excludes directly at the knife back, without manual cleaning, FPC double faced adhesive tapes
Processing efficiency improves.
It is described above that not this new technical scope is imposed any restrictions, it is all according to the utility model technical spirit to
On embodiment any modification, equivalent variations and the modification made, in the range of still falling within this new technical scheme.
