Detailed Description
The present invention will be described in detail with reference to examples, which are only preferred embodiments of the present invention and are not intended to limit the present invention.
Referring to fig. 1 and 2, a frame-shaped double-sided adhesive for a touch module according to the present invention includes four strip-shaped double-sided adhesives 1 connected end to form a frame, wherein one end of each strip-shaped double-sided adhesive 1 is provided with a groove 2, and the other end thereof is provided with a protrusion 3 corresponding to the groove 2. Because the one end that every strip two-sided glues 1 is provided with recess 2, and its other end is provided with the arch 3 corresponding with recess 2, after four strip two-sided glues 1 end to end interconnect become the frame type, two strip two-sided joints of gluing 1 have then had more the protruding 3 of one deck to block the dust to improved the two-sided dustproof ability who glues of frame type by a wide margin, made it more be applicable to the touch-control module, avoided producing MURA.
Referring to fig. 1 to 4, further, the groove 2 is disposed in the middle of one end of the strip-shaped double-sided adhesive 1, so that the obstruction of dust entering the inside is increased, and the dust-proof capability of the frame-shaped double-sided adhesive is further improved. Preferably, the grooves 2 are multiple, and each groove 2 is sequentially arranged at one end of the strip-shaped double-sided adhesive tape 1, so that the obstruction of dust entering the interior is further enhanced.
Referring to fig. 1 to 5, further, a release film 4 covering four strips of the double-sided adhesive tape 1 is further included.
Further, a hollowed part is arranged in the middle of the release film 4, so that the material of the release film 4 is saved.
Further, a film tearing handle 5 is arranged on the release film 4 so as to facilitate tearing off the release film 4.
Referring to fig. 1 to 6, further, an opening area is formed in the middle of the four strip-shaped double-sided adhesives 1, a concave through hole 6 is formed in the release film 4 at a corresponding position in the opening area, and the concave through hole 6 forms the film tearing handle 5. When the periphery of a product to be adhered is a frame wall without a notch, the film tearing handle 5 cannot interfere with the frame wall, so that the frame type double-sided adhesive can be normally adhered, the material of the film tearing handle 5 on the outer side can be omitted, and the production cost is further saved.
Referring to fig. 1 to 7, further, the release film 4 is not provided with a hollow portion, and the waste material 7 of the through hole 6 remains on the release film 4. The waste materials 7 of the concave through holes 6 are still remained on the release film 4, so that the release film 4 is kept in a complete state, and dust or other particles can be effectively prevented from entering the surface of a product.
Furthermore, the waste material 7 of the concave through hole 6 is provided with the viscose 8 which can assist in removing the waste material 7 of the concave through hole 6 and avoid the difficulty in tearing the film.
Further, the concave through hole 6 is formed in the edge of the opening area, and the difficulty in film tearing is further avoided.
Referring to fig. 8, further, the upper surface and the lower surface of the strip-shaped double-sided adhesive 1 are respectively provided with a weak-viscosity glue 11 and a strong-viscosity glue 12. Touch module parts such as the diaphragm in order to be adapted to needs attached, utilize the one side of weak viscidity glue 11 to paste the diaphragm, gluey frame is pasted to the one side of strong viscidity glue 12 to prevent that the diaphragm from warping.
Further, the initial adhesion ratio of the strong adhesion glue 12 to the weak adhesion glue 11 is 2:1 to 50:1, and the membrane is pulled by controlling the adhesion of the glue to avoid MURA, so that the membrane is prevented from deforming.
The above examples only show the embodiments of the present invention, and the description is specific and detailed, but not understood as the limitation of the scope of the utility model, but all the technical solutions obtained by using the equivalent substitution or the equivalent transformation should fall within the scope of the utility model.
