Description

Technical Field

[0001] The utility model relates to the technical field of foam, and more specifically to a foam structure capable of automatically discharging air bubbles. Background Art

[0002] Foam double-sided adhesive is a double-sided adhesive composed of foam substrate and adhesive, which has the characteristics of strong adhesion, good holding power, good waterproof performance, strong temperature resistance and strong UV protection. The substrates of foam double-sided adhesive are divided into EVA foam, PE foam, PU foam, acrylic foam and high foaming, etc., and the adhesive system is divided into oil glue, hot melt glue, rubber and acrylic glue. It is widely used in the fields of electronic market, automobile market, home market, such as mobile phones, computers, digital cameras, mechanical panels, membrane switches, automobile exterior decorative strips, automobile parts, automobile logos, automobile perfumes, hooks, furniture, toys, handicrafts, window gaps, door gaps, etc.

[0003] At present, there are more and more touch screens. When the touch screen and the client shell are bonded together, double-sided foam adhesive is needed for bonding. In the prior art, when double-sided foam adhesive is used for bonding, air cannot be discharged in the wider area of ​​the foam, resulting in foam bulging, which causes poor appearance and affects production. Therefore, we have made improvements on this and proposed a foam structure with automatic air bubble discharge.

[0004] For example, a Chinese patent (publication number: CN213169441U) discloses a new type of CTP laminating foam, and its specification discloses: With the development of science and technology, more and more display screens are appearing, and their display modules usually need laminating foam as frame glue on the outside. Existing CTP laminating foam products are all closed as a whole. Because the foam of this structure is a circle of closed type, when it is laminated with the display module, some gas will be generated in the closed area of ​​the foam, causing bubbles to appear in the product. Because it is closed, it is not easy to eliminate the gas with a defoaming machine, which causes product defects and affects the overall appearance and function of the product. The above patents can prove the defects of the existing technology. Utility Model Content
