[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.
[0024] It should be noted that the term "one end" and similar expressions used in this article are only for illustrative purposes and do not represent the only implementation method.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0026] See also Figure 4 , Figure 5 , Figure 6 In one embodiment of the utility model, the rolled double-sided adhesive comprises a reel 10, a double-sided adhesive body 20 and a tape 30, the tape 30 is wound on the reel 10, the double-sided adhesive body 20 is attached to the tape 30, the tape 30 comprises a protection zone 31 and a side material zone 32, a pre-breaking line 33 is set between the protection zone 31 and the side material zone 32, the protection zone 31 is attached to the double-sided adhesive body 20, the protection zone also comprises a tearing handle 311, and the waste material after the double-sided adhesive body 20 is torn off by the tape 30 is wound up and reused.
[0027] In this embodiment, the diameter of the reel 10 is 3 inches, and the outer diameter after winding is ≤90 mm, which meets the requirements for the use of general winding machines.
[0028] In this embodiment, the material of the roll tape 30 is PET or PI heavy release film.
[0029] In this embodiment, the double-sided adhesive body 20 is attached to the protection area 31 of the roll tape 30 , with the attached surface facing the roll 10 .
[0030] In this embodiment, the double-sided adhesive body 20 and the tape 30 are bonded together using a hot pressing process.
[0031] In this embodiment, the double-sided adhesive body 20 is square.
[0032] It is understandable that, in other embodiments, the double-sided adhesive body 20 may be circular or have a connection pattern with a fixed connection method.
[0033] In this embodiment, the boundary of the protection zone 31 is larger than the boundary of the double-sided adhesive body 20. The pre-break line 33 between the protection zone 31 and the edge material zone 32 is punched out by a semi-punching process, and the recommended length of the connection point of the pre-break line 33 is 0.1-0.15mm. In this way, since the boundary of the protection zone 31 is larger than the boundary of the double-sided adhesive body 20, and the semi-punching pre-break between the protection zone 31 and the edge material zone 32 is formed, the protection zone forms a semi-punching pre-break structure, which can prevent the double-sided adhesive body 20 from overflowing and sticking to the pre-break line 33, making it difficult to separate. The semi-punching pre-break of the protection zone can prevent the double-sided adhesive body 20 from falling off. When the double-sided adhesive body 20 is to be attached to a touch screen or other components, the semi-punching pre-break structure and the double-sided adhesive body 20 can be easily picked up and separated by automated equipment.
[0034] In this embodiment, the tear handle 311 is in the shape of an elongated strip, and the tear handle 311 extends toward the edge of the double-sided adhesive body 20 close to the roll tape 30 .
[0035] This embodiment does not impose any substantial limitation on the shape and position of the tear handle 311 .
[0036] In this embodiment, the end of the tear handle 311 away from the center of the protection zone is set as a movable end, and the movable end is provided with a color block. The setting of the movable end and the color block facilitates the automatic equipment to identify the double-sided adhesive body 20 to be torn off, and after being attached to a component such as a touch screen, it is convenient to distinguish and separate the semi-punched structure and the double-sided adhesive body 20.
[0037] In this embodiment, the waste material after the double-sided adhesive body 20 is torn off the tape is automatically wound by a winding machine, and the protection area 31 on the waste material faces the reel to form a double-sided adhesive surface of the roll, so that the tape can be reused.
[0038] In summary, a heavy release film is directly used as a tape 30 to attach the double-sided adhesive body 20 through the roll double-sided adhesive, and a pre-cutting design and a tearing handle 311 are designed on the tape 30, so that the double-sided adhesive body can be automatically torn off by the equipment, and after the double-sided adhesive body is adhered, it is convenient to set a pre-cutting structure and the double-sided adhesive body 20 on the adhesive surface to separate. After the double-sided adhesive body 20 is torn off, the tape 30 can be rolled up again, reducing the process of transferring the double-sided adhesive body and does not require an additional tape, saving costs.
[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
