Description
Technical Field
The invention belongs to the field of processing of polymer composite materials, and particularly relates to a flat-cutter die cutting process without knife mark.
Background
The functional polymer composite material is matched with an adhesive material to prepare a functional adhesive product which is attached to the surface of the flexible circuit board to play the roles of shielding, conducting, reinforcing and the like. The adhesive material is susceptible to temperature and generates glue overflow phenomena of different degrees. As shown in fig. 1 and fig. 2, the functional adhesive product structure cannot leave any cut mark on the second layer material, and the overflow glue is embedded into the cut mark, which is prone to poor peeling. The common processing flow in the prior flat cutter technology is as follows: 1. firstly, die cutting the third layer, and compounding the raw material of the second layer; 2. die cutting the first layer; 3. assembling the step 1 and the step 2 through a jig; 4. and die cutting to form the second layer.
The prior art has the following defects:
1. in the processing step 2, an auxiliary material is additionally used for supporting the bottom protective film for auxiliary processing, and the width is increased by more than 6mm compared with the width of the product;
2. requires assembly and has low productivity.
Disclosure of Invention
The technical problem to be solved by the invention is how to reduce the cost and improve the productivity.
The invention is realized by the following technical scheme:
the utility model provides a no sword seal flat knife cross cutting technology, includes first layer protection film, second floor log and third layer protection film, adds the auxiliary layer between first layer and second layer, and the auxiliary layer is the type membrane that can extract from to process through following steps:
firstly, die cutting a third layer of protective film, and compounding the protective film on the surface of a raw material of a second layer;
compounding the protective film of the first layer and the release film of the auxiliary layer together, and then attaching the protective film and the release film to the second layer;
step three, die-cutting the first layer, and discharging all the auxiliary layers and the first layer of waste materials after die-cutting;
and step four, finally, die cutting and processing the appearance of the second layer.
Preferably, the first protective film is formed on the second layer raw material without a cutting mark.
Preferably, when the first protective film is die-cut in the third step, the cutting die cuts into the auxiliary layer to a depth smaller than the thickness of the auxiliary layer.
Preferably, the width of the auxiliary layer is larger than 2 mm. .
Preferably, the material edge of the auxiliary layer and the processing position of the first layer are between 0.2mm and 1 mm.
The invention has the beneficial effects that: according to the invention, the detachable release film auxiliary layer is arranged between the first layer and the second layer, the first layer is punched and cut into a shape on the auxiliary layer, and is attached to the second layer after waste materials are stripped, so that two layers of materials are punched without tool marks, meanwhile, no jig is required for assembly, the cost is reduced, and the productivity is improved.

Detailed Description
The present invention will be further described with reference to the following examples.
Examples
The invention relates to a non-knife-printing flat knife die cutting process of a high polymer composite material, which comprises a first protective film layer 1, a second raw material layer 2 and a third protective film layer 3, wherein an auxiliary layer 4 is additionally arranged between the first protective film layer and the second protective film layer, is a detachable release film and is processed by the following steps:
firstly, die cutting a third layer of protective film, and compounding the protective film on the lower surface of the raw material of the second layer;
compounding the protective film of the first layer and the release film of the auxiliary layer together, and then attaching the protective film and the release film to the upper surface of the second layer;
step three, die-cutting the first layer, wherein the depth of the cutting die cutting into the auxiliary layer is about 0.02mm when the first layer is die-cut, the whole auxiliary layer cannot be cut off, and all the auxiliary layer and the first layer of waste materials are discharged after the die-cutting is finished; the auxiliary layer is not cut off, so that the first layer of waste materials are removed, and the whole auxiliary layer is convenient to remove;
and step four, finally, die cutting and processing the appearance of the second layer.
The cutting die preferably cuts into the secondary layer in the third step in the range of 0.01mm to 0.03mm when die cutting the first layer.
The auxiliary layer in this embodiment is a PET release film with a width of 10 mm.
In the embodiment, the material edge of the auxiliary layer and the processing position of the first layer are between 0.2mm and 1mm, and when the material edge of the auxiliary layer is less than 0.2mm, a cutting mark is left on the second layer; beyond 1mm, this can result in poor bubble wrinkling after the first layer is laminated to the second layer.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to explain the principles of the invention, and that various modifications and alterations can be made by those skilled in the art without departing from the spirit and scope of the invention.
