Die-cut adhesive structure and forming method thereof

Abstract

The invention discloses a die cutting rubberizing structure and a forming method thereof. The die cutting rubberizing structure comprises a release film and a plurality of gum and metal pieces located on the release film, wherein the projections of each metal piece and the corresponding gum cast on the release film are completely coincided with each other. A suction nozzle is used for penetrating through each metal piece after stamping through a second through hole on a second upper template, a gum piece is cut by the second upper template and the gum and the metal pieces are simultaneously accommodated in the second through hole, so that the gum and the metal pieces are completely coincided with each other.

Description

Technical field [0001] The invention relates to a die-cutting glue-applied structure and a forming method thereof, in particular to a die-cutting glue-applied structure and a forming method thereof for glue application. Background technique [0002] Existing smooth products (such as metal parts) need to be pasted with a layer of tape, commonly known as back glue, to prevent scratches on the metal surface, and to help solve the problem of water or dust sticking to the surface of the metal parts, affecting subsequent manufacturing Craft. [0003] The traditional method is to stamp several metal parts on a metal plate through a precision stamping die, cut several backing glues of the same size as the metal parts in another set of molds, and combine the stamped metal parts with the backing glue The product is glued together by automated equipment or operators, commonly known as glue. This molding process requires time and more labor costs, and the metal parts after glue cannot be alig...

Problems solved by technology

[0002] Existing smooth products (such as metal parts) need to be pasted with a layer of adhesive tape, commonly known as back glue, to prevent scratches on the metal surface, and it is beneficial to solve the problem of water or dust sticking on the surface of metal parts, affecting subsequent manufacturing craft

[0003] The traditional method is to stamp several metal parts on the metal plate through a precision stamping die, cut several back adhesives of the same size as the metal parts in another set of dies, and combine the stamped metal parts with the back adhesive The product is pasted together by automated equipment or operators, commonly known as gluing. This molding process requires more time-consuming labor costs, and the metal parts after gluing cannot be aligned with the adhesive, which is prone to misalignment and seriously affects The tightness of the finished product, such as figure 1 shown

[0004] In addition, the existing forming method also puts the metal plate and the backing film in the mold at the same time for simultaneous stamping and cutting. However, in this forming method, due to the flexibility of the backing film, when cutting the metal part, it will be in the metal part. Burrs are generated on the periphery. If the die-cut metal parts are attached to the corresponding products, the burrs will enter the electronic equipment with water or other dirt, affecting the waterproof performance of the electronic equipment
