s340: the transparent second protective film 152 is covered at the through hole 141, and the second protective film 152 simultaneously covers a portion of the first protective film 151.
Specifically, in the manufacturing process of the foam protection assembly of the embodiment, the transparent second protective film 152 covered at the through hole 141 is a film made of PCTA material, and the PCTA material is a copolyester plastic raw material. Has high transparency, good toughness and impact strength, excellent low-temperature toughness, high tear resistance, good processability and excellent chemical resistance. When the foam protection component produced by the preparation process of the foam protection component in this embodiment is attached to an electronic product, the foam protection component with the protective film 150 needs to be torn off from the sticker 500 to expose the second double-sided adhesive 122, the second double-sided adhesive 122 is attached to a certain part of the electronic product, after the attachment, the protective film 150 is torn off to expose the first double-sided adhesive 121, and then other parts of the electronic product are attached to the foam protection component. Wherein, can understand ground, through cover the first protection film 151 that has the colour on the cotton material area 110 of bubble in through-hole 141 one side, can mark the direction of the cotton protective component of bubble, when the installation protection bubble is cotton, make things convenient for the staff to discern the positive and negative of the cotton protective component of bubble on the sticker 500 to improve accuracy and the efficiency of pressing from both sides the cotton protective component of bubble of getting.
In detail, with reference to fig. 7, before punching the foam tape 110 and the protective film 150, the following steps are further included:
s500: the portion of the foam tape 110 covered with the first protective film 151 is cut away to form a slit 160 on the foam tape 110 opposite to the through hole 141 in the width direction.
The foam material belt 110 covered by the first protection film 151 is partially cut off, so that a part of the first protection film 151 in a finished product produced by the preparation process of the foam protection assembly of the embodiment is bonded on the foam material belt 110 between the through hole 141 and the cutting groove 160, and the other part is suspended in the opening of the cutting groove 160, when the foam material belt 110 attached with the protection film 150 is finally formed according to the shape punching of the foam protection assembly, the first protection film 151 forms a tearing hand protruding out of the side wall of the foam body 142, and a worker can conveniently clamp the first protection film 151 and the second protection film 152 covered on the first protection film 151 when tearing off the foam protection assembly from the sticker 500, so that the foam protection assembly can be torn and conveniently installed.
Referring to fig. 7, specifically, before punching the through holes 141 on the foam tape 110, the following steps are further included:
s100: the double-sided adhesive and the release film are sequentially attached to the first surface and the second surface of the foam tape 110, wherein the double-sided adhesive and the release film are respectively a first double-sided adhesive 121 and a first release film 131 attached to the first surface, and a second double-sided adhesive 122 and a second release film 132 attached to the second surface.
Before punching the through holes 141, the double faced adhesive tape is attached to the foam material tape 110, so that the through holes 141 can be formed on the foam material tape 110 and the double faced adhesive tape when punching is performed, the production requirements are met, the through holes 141 in the foam material tape and the double faced adhesive tape are formed simultaneously, the production process is simplified, the operation is simple, and the production efficiency is improved. Before punching the through hole 141, release paper is attached to the double-sided adhesive, so that the double-sided adhesive can be prevented from being contaminated in the process of punching the through hole 141 to influence the performance of the foam protection assembly, and the yield of products is further ensured.
With reference to fig. 9, specifically, attaching a double-sided adhesive and a release film to the first side and the second side in sequence includes the following steps:
s110: sequentially attaching a first release film 131 and a first double-sided adhesive 121 to the first carrier film 300;
s120: attaching the foam material belt 110 to the first double-sided adhesive 121;
s130: the second double-sided adhesive 122 and the second release film 132 are sequentially attached to the foam tape 110.
With reference to fig. 1 and 2, the first carrier film 300 can support the foam tape 110 during the transmission of the foam tape 110, so as to prevent the structure formed by combining the foam tape 110, the double-sided adhesive and the release film from being broken during the transmission or punching process, thereby ensuring the normal operation of the production line.
Referring to fig. 10, specifically, the first release film 131 and the first double-sided adhesive 121 are sequentially attached to the first carrier film 300, which includes the following steps:

In connection with fig. 1 and 2, the supporting effect can be further enhanced, in particular, by providing the edge strip 200. And the first release film 131 is attached to the surface of the first carrier film 300 between the two edge strips 200, so that the release film can be conveniently peeled off when the protective film 150 is attached. Specifically, referring to fig. 4, when the manufacturing process of the foam protection assembly of the present embodiment is implemented, two sets of through holes 141 are simultaneously punched on the foam tape 110, and two sets of protective films 150 are simultaneously attached, so that the tape with two rows of foam protection assemblies can be produced in the production process, thereby improving the production efficiency. When the protection film 150 is attached to the foam tape 110, the first protection film 151 is located on a side where the two sets of through holes 141 depart from each other, and a distance between the two edge bars 200 is greater than a distance between the two rows of foam bodies 142, so that the first protection film 151 can be adhered to the first double-sided adhesive 121. Of course, only one set of through holes 141 may be punched on the foam tape 110, and the distance between the two edge strips 200 is greater than the width of the foam body 142.
Referring to fig. 8, specifically, attaching the protective film 150 to the first surface further includes:
s310: peeling the first carrier film 300 to expose the first release film 131;
s320: the first release film 131 is peeled off to expose the first double-sided adhesive 121.
Specifically, in conjunction with fig. 3 and 4, in order to not hinder the attachment of the protective film 150 on the foam tape 110 during the production of the foam protection assembly, the edge strip 200 is purposely disposed at the edge of the foam tape 110, and after the first carrier film 300 and the first release film 131 are peeled off, the first double-sided adhesive 121 is exposed for the attachment of the protective film 150, wherein the edge strip 200 is adhered to the edge of the first double-sided adhesive 121, and still can support the foam tape 110 without blocking the peeling of the first release film 131.
In detail, with reference to fig. 7, before punching the foam tape 110 and the protective film 150, the following steps are further included:
the foam tape 110 to which the protective film 150 is attached to the second carrier film.
Specifically, the first carrier film 300 is peeled off before the protective film 150 is attached, and a carrier film needs to be attached again to support the foam tape 110 to which the protective film 150 is attached, so as to prevent the foam tape 110 from being broken during the post-punching.
In detail, with reference to fig. 7, after punching the foam tape 110 and the protective film 150, the following steps are further included:
s700: peeling the second release film 132 to expose the second double-sided adhesive 122;
s800: reapplying the sticker 500 on the second double-sided adhesive 122;
