Detailed Description

In order to describe the technical solution of the above utility model in more detail, the following specific examples are given to demonstrate the technical effects; it should be emphasized that these examples are for illustrative purposes only and are not limiting to the scope of the present invention.

The utility model provides a liquid crystal display panel fixed adhesive tape, as shown in figure 2, including what set gradually from type membrane 10, first layer double faced adhesive tape 20, bubble cotton 30 and second floor double faced adhesive tape 40 from the initiating terminal that tears of type membrane 10, the length from type membrane 10 is longer than bubble cotton 30, the length of first layer double faced adhesive tape 20 weak point in bubble cotton 30. In the utility model, the release film 10 is arranged to protrude out of the foam 30 at the tearing start end of the release film 10, and when an operator operates the release film 10 to tear, the edge of the release film 10 is not stuck by the first layer of double faced adhesive tape 20 and is a free end, so that the release film 10 can be easily picked up and separated from the first layer of double faced adhesive tape 20; similarly, at the tearing start end of the release film 10, the first layer of double-sided adhesive 20 is set to retract to the inner side of the foam 30, that is, the edge of the foam 30 is not stuck by the first layer of double-sided adhesive 20, so that the stressed position of the foam 30 avoids the section of the foam 30 and moves inwards to the upper surface of the foam 30, and the section of the foam 30 is easier to tear than the upper surface, so that the structure avoids the tear of the foam 30 to a certain extent, and the production yield and the production efficiency are improved.

Preferably, the length of the release film 10 is more than 5mm, preferably 10mm longer than that of the foam 30, so as to facilitate manual operation; preferably, the length of the first layer of double-sided adhesive 20 is 0.5mm to 5mm, preferably 1mm to 3mm shorter than the length of the foam 30, for example, the length of the first layer of double-sided adhesive 20 is 2mm shorter than the length of the foam 30, on one hand, the position of the cross section of the foam 30 is avoided, on the other hand, the overall adhesion of the tape is not greatly affected, and the problem of poor adhesion and the like caused by the fact that the first layer of double-sided adhesive 20 is not too long and is not attached to the foam 30 is avoided.

Preferably, at the tearing start end of the release film 10, the edge of the first layer of double-sided adhesive tape 20 is arc-shaped, so as to further disperse the stress position of the foam 30 and protect the foam 30 from being torn.
