[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0031] The utility model provides a high-efficiency and low-waste circular double-sided adhesive tape, which includes a large-plate double-sided adhesive tape, wherein the large-plate double-sided adhesive tape includes a light release film, a double-sided adhesive tape body and a heavy release film which are sequentially stacked from top to bottom, and the large-plate double-sided adhesive tape includes a first waste row portion, a small double-sided adhesive portion, a second waste row portion and a large double-sided adhesive portion which are arranged in a surrounding manner from inside to outside, wherein the first waste row portion is in a square shape, and the small double-sided adhesive portion, the second waste row portion and the large double-sided adhesive portion are all in a mouth shape.

[0032] Since the large-size double-sided adhesive tape includes, from the inside to the outside, a first row of waste parts, a small double-sided adhesive part, a second row of waste parts and a large double-sided adhesive part, a U-shaped punching tool can be designed during production. The outer dimensions of the U-shaped punching tool are consistent with the outer dimensions of the second row of waste parts. The first row of waste parts is punched out using a traditional punching tool, which can punch out the first row of waste parts and the second row of waste parts at one time, or can punch out in steps. In this way, the U-shaped double-sided adhesive tape structure designed by the utility model can punch out two U-shaped double-sided adhesive tapes with the same raw material size, and can punch out two U-shaped double-sided adhesive tapes of different sizes at one time, which greatly improves production efficiency and reduces waste discharge rate, giving it a cost advantage and improving product competitiveness.

[0033] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

[0034] Example 1

[0035] See also Figure 1The utility model provides a high-efficiency, low-waste circular double-sided adhesive tape, which includes a large-size double-sided adhesive tape 100. The large-size double-sided adhesive tape 100 includes a light release film 1, a double-sided adhesive body 2, and a heavy release film 3 stacked in sequence from top to bottom. The large-size double-sided adhesive tape 100 includes a first row of waste parts 101, a small double-sided adhesive part 102, a second row of waste parts 103, and a large double-sided adhesive part 104 that are surrounded and connected to each other from the inside to the outside. The shape of the first row of waste parts 101 is square, and the shapes of the small double-sided adhesive part 102, the second row of waste parts 103, and the large double-sided adhesive part 104 are all in the shape of a square. That is, the large-size double-sided adhesive 100 includes a light release film 1, a double-sided adhesive body 2 and a heavy release film 3 in the longitudinal distribution, and includes a first row of waste parts 101, a small double-sided adhesive part 102, a second row of waste parts 103 and a large double-sided adhesive part 104 in the transverse distribution. The first row of waste parts 101, the small double-sided adhesive part 102, the second row of waste parts 103 and the large double-sided adhesive part 104 all include a light release film 1, a double-sided adhesive body 2 and a heavy release film 3. When in use, the first row of waste parts 101 and the second row of waste parts 103 are punched out to obtain the small double-sided adhesive part 102 and the large double-sided adhesive part 104.

[0036] Of course, for some scenarios with lower requirements, the second waste discharge part 103 can also be used as a circular double-sided adhesive tape with lower requirements, so that three circular double-sided adhesive tapes can be obtained in one punching, which greatly improves production efficiency and reduces waste discharge rate.

[0037] In other embodiments, a third waste discharge portion may be added externally, and then a third double-sided adhesive portion may be added outside the third waste discharge portion, thereby further improving efficiency and reducing waste discharge rate.

[0038] Furthermore, the length and width of the first row waste portion 101 are 85.01 mm and 46.63 mm respectively, the length and width of the small double-sided adhesive portion 102 are 93.01 mm and 54.31 mm respectively, the length and width of the second row waste portion 103 are 105.01 mm and 66.63 mm respectively, and the length and width of the large double-sided adhesive portion 104 are 109.57 mm and 71.2 mm respectively.

[0039] Example 2

[0040] As a further optimization solution of Example 1, in this embodiment, a film tearing handle 4 is provided on the light release film 1 to facilitate tearing off the light release film 1 .

[0041] Furthermore, a concave through hole 5 is provided on the light release film 1, and the residual material of the concave through hole 5 forms a film tearing handle 4, so there is no need to add a film tearing handle 4 on the periphery of the light release film 1. Therefore, the film tearing handle 4 will not be unable to be placed due to the limitation of the peripheral space, avoiding the need to use tweezers to lift the film when the peripheral space is limited, thereby saving labor costs; and the material of the peripheral film tearing handle 4 can be omitted, which can greatly reduce material costs.

[0042] Furthermore, the waste material 6 of the “concave”-shaped through hole 5 remains on the light release film 1. Before the light release film 1 is torn off, the waste material 6 is still connected to the light release film 1, which can effectively prevent dust or other particles from entering the product surface. Since the waste material 6 is still connected to the light release film 1, it is difficult to tear off the film tearing handle 4 at this time, so an adhesive area 7 can be set on the upper surface of the waste material 6, preferably adhesive, but not limited to this. When tearing off the upper light release film 1, the waste material 6 can be torn off with the adhesive first, and then the light release film 1 can be torn off with the film tearing handle 4.

[0043] Furthermore, the “concave”-shaped through hole 5 is arranged at the edge of the light release film 1 , so that the light release film 1 is easier to tear off, and the tearing handle 4 is not damaged due to high tearing difficulty.

[0044] Furthermore, each corner of the "concave"-shaped through hole 5 is provided with a rounded corner, so that the stress during film tearing is not concentrated at the corner, thereby avoiding the film tearing handle 4 from being torn due to stress concentration, and further improving the working efficiency.

[0045] Furthermore, the radius of the rounded corner is 1 mm.

[0046] Example 3

[0047] As a further optimization scheme of Example 1, in this embodiment, the double-sided adhesive body 2 includes a weak adhesive layer 21, a base material layer 22 and a strong adhesive layer 23 stacked in sequence from bottom to top. The weak adhesive layer 21 can be used to attach softer components such as the lower polarizer to prevent the lower polarizer from wrinkling when the temperature changes. The strong adhesive layer 23 can be attached to hard components to ensure adhesion.

[0048] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.
