Embodiment Construction
[0014] see figure 1 , the adhesive tape 10 according to Embodiment 1 of the present invention includes a base 11 , a first adhesive layer 13 and a second adhesive layer 15 . The base 11 is made of light guiding material, and includes a light incident surface 112 , two opposite light emitting surfaces 114 and an end surface 116 . The light incident surface 112 is opposite to the end surface 116 , and the two light exit surfaces 114 are parallel to each other, located on two sides of the light incident surface 112 , and the light incident surface 112 connects the two light exit surfaces 114 . Light can enter the substrate 11 from the light incident surface 112 and exit from the two light exit surfaces 114 . The first adhesive layer 13 and the second adhesive layer 15 are respectively disposed on the two light emitting surfaces 114 . Both the first adhesive layer 13 and the second adhesive layer 15 are made of optical radiation failure adhesive. In Embodiment 1 of the present ...

An adhesive tape comprises a substrate, a first adhesive layer and a second adhesive layer. The substrate is prepared from a light guide material, and the substrate includes a light incident surface and two light emitting surfaces, light can enter into the substrate from the light incident surface and emits from the two light emitting surfaces. The first adhesive layer and the second adhesive layer are respectively arranged on the two light emitting surfaces. The first adhesive layer is prepared from an optical radiation failure adhesive, and the second adhesive layer is prepared from an optical radiation failure adhesive. Because the substrate of the adhesive tape is prepared from the light guide material, when a bonding workpiece is needed to be tore off from the adhesive tape, even if the bonding workpiece is non-transparency, the light can enter into the substrate from the light incident surface of the substrate, and then emits from the two light emitting surfaces to make the first adhesive layer and the second adhesive layer invalid, and the bonding workpiece is tore off. The invention also provides another adhesive tape, and the substrate of the adhesive tape comprises a light emitting surface.
Description
technical field [0001] The invention relates to an adhesive tape, in particular to an optical radiation failure adhesive tape. Background technique [0002] Optical radiation failure tape refers to a type of adhesive tape whose viscosity will be reduced after being irradiated by light. At present, optical radiation failure tapes, such as ultraviolet (UV) radiation failure tapes, are generally used to bond light-transmitting components during processing. When the tape needs to be torn off from the components, only UV light radiation tape is used. Its stickiness decreases, and the tape is peeled off again. However, when the optical radiation failure tape is used for other non-light-transmitting components, since the light cannot pass through the component radiation tape, the tape cannot be invalidated, so it is not applicable. Contents of the invention [0003] In view of the above, it is necessary to provide an adhesive tape suitable for bonding non-light-transmitting com...
