Detailed Description
The following describes the method for manufacturing the integrated conductive shielding product according to the present invention in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 5 to 8, a method for manufacturing an integrated conductive shielding product includes the following steps:
step one, die cutting a fifth protective film 8 on the upper layer of the second bottom film, wherein a fourth protective film 7 is arranged on the lower layer of the second bottom film.
Step two, the PET3 is attached to the fifth protective film 8 for die cutting.
And step three, half cutting small holes of the conductive cloth on the first protective film 2 of the conductive cloth 1, taking away the small hole waste materials through the first protective film 2, and transferring the conductive cloth 1 with the holes to PET 3.
And step four, cutting the whole appearance of the product, and removing the waste materials of the outer frame.
And step five, pasting a shielding film 9 for packaging the product on the basis of the step four, pasting the shielding film 9 with the viscous PET except the product, die-cutting the appearance of the shielding film 9, and setting the distance between the appearance of the shielding film 9 and the outer frame of the product. Meanwhile, the second base film is avoided during die cutting. And (5) vertically slicing and cutting off the product to obtain a finished product which is finally sliced.
If the product is a multi-mold product, the separation line in the middle of the multi-mold product is not cut off in the step one. And step five, cutting off the whole multi-mold product, and trimming up and down.
In step five, the cut masking film 9 is carried away through the PE film 10 with adhesive properties. The set distance was 0.5 mm.
In this example, the masking film 9 was transparent PET with a thickness of 0.01 mm.
The thickness of the conductive cloth 1 is 0.06mm, the thickness of the first protective film 2 is 0.05mm, the thickness of the PET3 is 0.05mm, the thickness of the fourth protective film 7 is 0.05mm, and the thickness of the fifth protective film 8 is 0.075 mm. The conductive cloth 1 is a copper foil.
The invention will be described below by taking the production of a two-part product as an example.
Referring to fig. 5, a second base film (including a fourth protective film 7 of a lower layer and a fifth protective film 8 of an upper layer, which is a low-tack protective film) is loaded by a material roll Q1, and at a station G2, the fifth protective film 8 is die-cut by a cutting die D1', but without cutting a parting line between two die products.
The material roller Q4 puts down PET3, the PET3 is attached to the second bottom film at a station G3 and die-cut through a cutting die D2', and the PET waste materials are recycled through the material roller Q5.
The conductive cloth 1 with the first protection film 2 is put down from a material roller Q7, the conductive cloth 1 with the first protection film 2 is utilized to half cut the conductive cloth small holes through a cutting die D3' at a working position G4, the first protection film 2 takes away the small hole waste materials and discharges the waste materials through the material roller Q6, and the conductive cloth 1 with the holes is pasted on PET 3.
At station G6, the product is cut into its overall shape by a knife die D4' and the outer frame scrap is recovered by a feed roll Q8.
The product with the cut overall shape was further attached with a transparent PET (i.e., a masking film 9) having a thickness of 0.01mm for packaging the product, and attached with an adhesive PET other than the product, and the masking film 9 was dropped from a feed roller Q9. The transparent PET with the thickness of 0.01mm (0.5 mm larger than the outer frame of the product) is die-cut at the station G10 by a cutting die D5', and meanwhile, the second bottom film is avoided (the second bottom film can be normally torn off) during die-cutting. The cutting die D5' increases the integral cutting line and the upper and lower trimming edges between the two dies, increases the cutting vertical line of each die, and directly produces the finished product after the product comes out.
The cut masking film 9 is carried by the tacky PE film 10, and the PE film 10 is dropped from the stock roll Q10, and the cut masking film 9 is taken up to the stock roll Q11.
In the invention, a low-viscosity protective film is used as a bottom film, and the glue exposed part of the product is laminated by transparent PET with the thickness of 0.01mm, so that manual packaging is not influenced.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any alternative or alternative method that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the scope of the present invention.
