[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 when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only 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 in the technical field 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. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] Reference Figure 1 and Figure 2 A rolled double-sided adhesive structure includes: a barrel 10, a heavy release film 20 and a double-sided adhesive 30, wherein the heavy release film 20 is rolled on the barrel 10, and the double-sided adhesive 30 is arranged on the heavy release film 20 at intervals, and the adhesive surface of the double-sided adhesive 30 faces the barrel 10.

[0027] The present embodiment provides a double-sided adhesive roll structure, which directly uses the heavy release film 20 as a roll to complete the roll of the double-sided adhesive 30 without using a roll, thereby reducing the generation of waste in the double-sided adhesive 30 attachment process and reducing the cost of accessories.

[0028] Furthermore, a half-punching line 201 is provided in the middle position adjacent to the double-sided adhesive 30, and the half-punching line 201 is composed of a cutting line 2011 and a connecting point 2012 arranged at intervals, and the length of the connecting point 2012 is 0.1-0.15 mm. By providing the half-punching line 201, the double-sided adhesive 30 is more easily separated from the heavy release film 20, thereby improving the production efficiency of the attachment process.

[0029] Furthermore, the surface area of ​​the heavy release film 20 between the two half-punching lines 201 is larger than the surface area of ​​the double-sided adhesive tape 30, and the distance between the edge of the double-sided adhesive tape 30 and the corresponding edge of the heavy release film 20 is 0.3-0.5 mm. By setting the surface area of ​​the heavy release film 20 to be larger than the surface area of ​​the double-sided adhesive tape 30, a blank area is formed around the double-sided adhesive tape 30, which can prevent the adjacent double-sided adhesive tapes 30 from adhering together due to overflow of glue, thereby affecting the separation effect.

[0030] Further, a tear handle 202 is provided at the bottom of the heavy release film 20 corresponding to the double-sided adhesive 30. The tear handle 202 is provided to facilitate the tearing of the heavy release film 20 after the attachment process.

[0031] To further adapt to the automated attachment operation of the double-sided adhesive 30, the thickness of the heavy release film 20 is 0.03 mm to 0.1 mm, the diameter of the barrel 10 is 76.2 mm, and the outer diameter of the roll of the roll double-sided adhesive structure is ≤90 mm.

[0032] 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.
