The first conductive double-sided adhesive strip and the second conductive double-sided adhesive strip are respectively compounded with a blue release film on their surfaces; the length edges on both sides of the rectangular sheet-like composite main material are folded over and bonded by the hot-melt adhesive strip to form a cylindrical packaging component body with a rectangular cross-section with an insulating PI film inside and a copper foil tape outside, and on the cylindrical packaging component body, the foam strip is located on the inner wall of the surface where the hot-melt adhesive is located, the second conductive double-sided adhesive strip is located on the outer wall opposite to the foam strip, and the first conductive double-sided adhesive strip is located on the outer wall adjacent to it.

[0005] One end of the two blue release films protrudes from the edge of the conductive double-sided adhesive strip and the rectangular sheet-shaped composite main material.

[0006] The present invention also provides a production process for wrapping the above-mentioned foam copper foil tape shielding component, and the production process comprises the following steps:

[0007] Step a: Use a rotary die-cutting machine to produce rectangular sheet composite main materials:

[0008] First, the non-release surface of the blue release film strip and the first blue silicone protective film strip are compounded by the first compounding roller group, and then die-cut by the first die-cutting roller group to cut two fracture lines in the width direction of both ends of the two blue release films;

[0009] Then, the conductive double-sided adhesive tape is compounded on the release surface of the blue release film tape by the second compounding roller group, the release paper of the conductive double-sided adhesive tape is peeled off, and then a layer of white PET release film tape is compounded and enters the second die-cutting roller group for die-cutting. The second die-cutting cuts out a first conductive double-sided adhesive tape near the middle and two long side fracture lines of its blue release film, and at the same time cuts out the interval fracture line between the two conductive double-sided adhesive tapes and the two blue release films (the interval fracture line on the outside is also the inner long side fracture line of the second conductive double-sided adhesive tape);

[0010] Then, the waste material is adhered to the upper surface of the material strip at the discharge end of the second die-cutting roller group by sealing tape and rolled up for removal; the waste material is the white PET release film material strip and the waste conductive double-sided adhesive tape and blue release film waste in the interval area between the two conductive double-sided adhesive strips and the two blue release films cut out by die-cutting; the copper foil tape material strip is compounded by the third composite roller group on the upper surface of the material strip after the waste is discharged, and the release paper of the copper foil tape after the compounding is immediately discharged; the insulating PI film material strip is compounded on the surface of the copper foil tape material strip after the waste is discharged by the fourth composite roller group;

[0011] The five-layer composite tape is formed from bottom to top, which is a first blue silicone protective film tape, a blue release film tape with a gap in the middle, a conductive double-sided adhesive tape with a gap in the middle, a copper foil tape tape, and an insulating PI film tape;

After the composite, the release film waste of the foam material tape is peeled off and rolled up for removal. Then, the first blue release paper tape is composited by the sixth composite roller group, and then die-cut by the third die-cutting roller group. The third die-cutting forms a fracture line on the inner long side of the foam strip. After the die-cutting, the first blue release paper tape and the waste outside the fracture line of the long side of the foam strip are peeled off. The adhesive surface of the foam tape is exposed, and then after being turned by the lower roller of the third die-cutting roller group, the adhesive surface of the foam tape faces downward and is compounded with one side edge of the insulating PI film tape on the upper surface of the five-layer composite tape. After compounding, the upward-facing first transparent silicone protective film tape is removed, so that the non-adhesive surface of the foam tape faces upward and is exposed, forming a six-layer composite tape from bottom to top, which is the first blue silicone protective film tape, the blue release film tape with a gap in the middle, the conductive double-sided adhesive tape with a gap in the middle, the copper foil tape tape, the insulating PI film tape, and one side of which is compounded with a foam tape;

The fourth die-cutting forms a fracture line on the inner long side of the hot-melt adhesive tape. After die-cutting, the waste release film of the hot-melt adhesive tape and the waste outside the fracture line of the long side of the hot-melt adhesive tape are removed, and then the lower roller of the fourth die-cutting roller group is turned to make the hot-melt adhesive tape face downward and compound with the other side edge of the insulating PI film tape on the six-layer composite tape. After compounding, the second transparent silicone protective film tape is peeled off and the waste is discharged, forming a new six-layer composite tape which is, from bottom to top, the first blue silicone protective film tape, the blue release film tape with a gap in the middle, the conductive double-sided adhesive tape with a gap in the middle, the copper foil tape, the insulating PI film tape, and one side of the foam tape compounded with the other half of the hot-melt adhesive tape;

[0014] The new six-layer composite material tape is die-cut by the fifth die-cutting roller group. The fifth die-cutting forms the outer frame fracture line of the rectangular sheet composite main material and the multiple strip hole fracture lines in the middle, and one end of the blue release film tape is not cut off, while the other end is cut off; and in the fifth die-cutting, the strip hole waste is eliminated by the first transparent PET acrylic protective film tape under the new six-layer composite material tape, and the waste outside the outer frame is eliminated from the top after die-cutting, and then, the second blue silicone protective film tape is compounded on the upper surface of the tape by the eighth composite roller group, and the adhesive surface of the second blue silicone protective film tape faces downward, and the first blue silicone protective film tape of the bottom layer is excluded after compounding; at this time, the tapes are from bottom to top: a blue release film tape with a gap in the middle, a conductive double-sided adhesive tape with a gap in the middle, a copper foil tape, an insulating PI film tape, and a second blue silicone protective film tape compounded with a foam tape on one side and a hot-melt adhesive tape on the other half, covering the foam tape and the hot-melt adhesive tape;

[0015] Finally, the second blue release paper tape and the second transparent PET acrylic protective film tape are sequentially stacked below the tape and then die-cut by the sixth die-cutting roller group. The sixth die-cutting is to cut the product into a rectangular sheet-shaped composite main material, and one end of the two blue release films in the rectangular sheet-shaped composite main material protrudes from a wide edge of the rectangular sheet-shaped composite main material; the second transparent PET acrylic protective film tape is not cut off by the sixth die-cutting, and the second transparent PET acrylic protective film tape is separated from the rectangular sheet-shaped composite main material and rolled up;

[0016] Step b: peel off the blue release paper and two blue release films formed by the second blue release paper tape on the rectangular sheet-shaped composite main material obtained in step a, and then use a jig to fold the length edges on both sides of the rectangular sheet-shaped composite main material and bond them with the hot-melt adhesive strip to form a cylindrical wrapping component body with a rectangular cross-section with an insulating PI film inside and a copper foil tape outside. On the cylindrical wrapping component body, the foam strip is located on the inner wall of the surface where the hot-melt adhesive is located, and the conductive double-sided adhesive strip is located on the outer wall opposite to the foam strip, thereby completing the production of the wrapped shielding component.

After die-cutting, the waste R11 of the release film carried by the hot-melt adhesive tape and the waste outside the fracture line of the long side of the hot-melt adhesive strip 3 are excluded, and then the lower roller of the fourth die-cutting roller group Q4 is turned to make the hot-melt adhesive tape R1 face downward and composite with the other side edge of the insulating PI film material strip P1 on the six-layer composite material strip S2 (this composite is pulled and composited by the second roller and the third roller in the fourth die-cutting roller group Q4, as shown in FIG.

[0048] The new six-layer composite material strip S3 is die-cut by the fifth die-cutting roller group Q5. The fifth die-cutting forms an outer frame fracture line of the rectangular sheet composite main material and multiple strip hole fracture lines in the middle. Among the two long side fracture lines of the outer frame fracture line, one long side fracture line forms an outer long side fracture line of the hot-melt adhesive strip and an outer long side fracture line of the second conductive double-sided adhesive strip and its blue release film, and the other long side fracture line forms an outer long side fracture line of the foam strip, and one end of the blue release film material strip L1 is not cut off, and the other end is cut off; and in the fifth die-cutting, the strip hole waste is removed from the bottom of the new six-layer composite material strip S3 through the first transparent PET acrylic protective film material strip Y1, and at the same time, after die-cutting, The outer frame waste S31 other than the outer frame is removed from the upper side, and then the second blue silicone protective film strip G2 is compounded on the upper surface of the strip through the eighth compounding roller group F8, and the adhesive surface of the second blue silicone protective film strip G2 faces downward, and the first blue silicone protective film strip G1 of the bottom layer is removed after compounding; at this time, the strips are, from bottom to top, the following: a blue release film strip L1 with a gap in the middle, a conductive double-sided adhesive strip D1 with a gap in the middle, a copper foil tape strip T1, an insulating PI film strip P1, and a second blue silicone protective film strip G2 with a foam strip M1 compounded on one side and a hot-melt adhesive strip R1 compounded on the other half, covering the foam strip M1 and the hot-melt adhesive strip R1;

[0049] Finally, the second blue release paper tape Z2 and the second transparent PET acrylic protective film tape Y2 are sequentially stacked below the tape and then die-cut by the sixth die-cutting roller group Q6. The sixth die-cutting is to cut the product into a rectangular sheet-shaped composite main material, and in the rectangular sheet-shaped composite main material, one end of the two blue release films 7 protrudes from a wide edge of the rectangular sheet-shaped composite main material; the sixth die-cutting does not cut the second transparent PET acrylic protective film tape Y2, the second transparent PET acrylic protective film tape Y2 is separated and rolled up from the rectangular sheet-shaped composite main material, and the rectangular sheet-shaped composite main material with the blue release paper 8 falls into the collection frame H1, and the second transparent PET acrylic protective film tape can be reused;
