Description

Technical Field

[0001] The utility model relates to the technical field of touch screen adhesive backing, and more specifically to a touch screen adhesive backing structure. Background Art

[0002] In the current electronic product market, touch screen technology has been favored by consumers for its intuitive and convenient operation. Whether it is a smartphone, tablet or other electronic device, the touch screen is an indispensable interactive interface. In order to meet the requirements of product appearance and performance, the back of the touch screen usually adopts a double-sided adhesive design. This design allows the touch screen to fit firmly on the entire machine casing, providing a stable and reliable touch experience;

[0003] However, in the actual production process, the attachment of double-sided adhesive faces a technical challenge - the problem of centering attachment. Due to the limitation of the traditional fixture positioning method, it is difficult to accurately attach the double-sided adhesive to the casing. Specifically, the traditional fixture usually positions by pressing the edge of the touch screen or the edge of the cover. Although this method is simple and direct, it is difficult to ensure the center position of the double-sided adhesive. Once the double-sided adhesive is offset, it will not only affect the appearance quality of the product, but also may affect the sealing and stability between the touch screen and the casing, thereby reducing the overall performance of the product. Therefore, we have made improvements to this and proposed a touch screen adhesive structure.

[0004] For example, a Chinese patent (publication number CN108202522A) discloses a positioning and laminating device, and its specification discloses: At present, the factory needs to perform double-sided tape laminating operations on an electronic device housing, and the operation steps are as follows: first place the electronic device housing to be laminated on a platform, then laminate one side of the double-sided tape on the electronic device housing, and then laminate the touch screen on the other side of the double-sided tape. However, in the above laminating operation, it is easy to skew the position of the double-sided tape, resulting in an unsightly appearance and also causing adverse effects on the subsequent assembly of the whole machine. The above patent can prove the defects of the existing technology. Utility Model Content

[0005] The technical problem to be solved by the embodiments of the utility model is that the double-sided adhesive is often offset due to the limitation of the positioning method of the clamp.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A touch screen adhesive structure, comprising: a double-sided adhesive body, on which a first positioning portion is arranged, the first positioning portion is located at two corners of the double-sided adhesive body, and is used to realize the positioning of the double-sided adhesive body and a clamp, so as to realize the centering of the double-sided adhesive body;

[0008] The first positioning portion includes a first positioning circular hole and a second positioning circular hole, and the first positioning circular hole and the second positioning circular hole are respectively opened at two corners of the double-sided adhesive body, and the first positioning circular hole and the second positioning circular hole are diagonally arranged. The present application provides precise positioning points for the positioning column of the clamp by arranging the first positioning circular hole and the second positioning circular hole at two diagonal corners of the double-sided adhesive body. The design of the first positioning circular hole and the second positioning circular hole not only facilitates the insertion of the positioning column of the clamp, but also effectively limits the moving range of the clamp, ensuring that the double-sided adhesive body can be centered on the cover plate of the touch screen. Since the double-sided adhesive body can be attached centered, the appearance defects caused by offset are avoided, the overall aesthetics of the product is improved, and the adjustment time in the production process is reduced through precise positioning design, thereby improving production efficiency.

[0009] As an improved manner of the present invention, the diameter of the first positioning circular hole is smaller than the diameter of the second positioning circular hole.

[0010] As an improvement of the utility model, second positioning parts are provided at the other two corners of the double-sided adhesive body, and the second positioning parts are used to realize the positioning of the double-sided adhesive body and the clamp to realize the centering of the double-sided adhesive body.

[0011] As an improvement of the utility model, the second positioning portion includes a first positioning elliptical hole and a second positioning elliptical hole, the first positioning elliptical hole and the second positioning elliptical hole are respectively opened at the other two corners of the double-sided adhesive body, and the first positioning elliptical hole and the second positioning elliptical hole are diagonally arranged.

[0012] As an improved manner of the present invention, the first positioning elliptical hole is arranged horizontally, and the second positioning elliptical hole is arranged vertically.

[0013] As an improvement of the present invention, the transverse length of the second positioning elliptical hole is the same as the diameter of the first positioning circular hole, and the vertical length of the second positioning elliptical hole is greater than the diameter of the first positioning circular hole.

[0014] As an improvement of the present invention, the transverse length of the first positioning elliptical hole is greater than the diameter of the first positioning circular hole, and the vertical length of the first positioning elliptical hole is the same as the diameter of the first positioning circular hole.

[0015] As an improved manner of the utility model, protective pieces are provided on both sides of the double-sided adhesive body, and the protective pieces are used for protecting the double-sided adhesive body before lamination.

[0016] As an improved manner of the utility model, the protective member includes a protective film, and the protective film is attached to the double-sided adhesive body.

[0017] As an improvement of the utility model, a tearing handle is provided at one end of the protective film, and the tearing handle is used to assist in tearing off the protective film.

[0018] Compared with the prior art, the embodiments of the present invention mainly have the following beneficial effects:

[0019] In order to solve the problem of double-sided adhesive often being offset due to the limitation of the positioning method of the clamp in the prior art, the present application provides precise positioning points for the positioning column of the clamp by setting a first positioning circular hole and a second positioning circular hole at two opposite corners of the double-sided adhesive body. The design of the first positioning circular hole and the second positioning circular hole not only facilitates the insertion of the positioning column of the clamp, but also effectively limits the movement range of the clamp, ensuring that the double-sided adhesive body can be attached to the cover plate of the touch screen in the center. Since the double-sided adhesive body can be attached in the center, the appearance defects caused by offset are avoided, the overall aesthetics of the product is improved, and the adjustment time in the production process is reduced through precise positioning design, thereby improving production efficiency.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present invention belongs; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Reference to "embodiments" herein means that specific features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] As described in the background technology, in the actual production process, the attachment of double-sided adhesive faces a technical challenge - the problem of centering the attachment. Due to the limitations of the traditional clamp positioning method, it is difficult to accurately center the double-sided adhesive on the casing. Specifically, the traditional clamp usually positions by pressing the edge of the touch screen or the edge of the cover. Although this method is simple and direct, it is difficult to ensure the center position of the double-sided adhesive. Once the double-sided adhesive is offset, it will not only affect the appearance quality of the product, but may also affect the sealing and stability between the touch screen and the casing, thereby reducing the overall performance of the product.

[0027] In order to solve this technical problem, the utility model provides a touch screen adhesive structure.

[0028] Specifically, please refer to Figure 1 , the touch screen adhesive structure specifically includes:

[0029] A double-sided adhesive body 1, on which a first positioning portion is provided, the first positioning portion is located at two corners of the double-sided adhesive body 1, and is used to realize the positioning of the double-sided adhesive body 1 and the fixture, so as to realize the centering of the double-sided adhesive body 1;

[0030] The first positioning portion includes a first positioning circular hole 101 and a second positioning circular hole 102 . The first positioning circular hole 101 and the second positioning circular hole 102 are respectively opened at two corners of the double-sided adhesive body 1 , and the first positioning circular hole 101 and the second positioning circular hole 102 are arranged diagonally.

[0031] The touch screen adhesive structure provided by the utility model can provide accurate positioning points for the positioning column of the clamp by arranging the first positioning circular hole 101 and the second positioning circular hole 102 at the two diagonal parts of the double-sided adhesive body 1. The design of the first positioning circular hole 101 and the second positioning circular hole 102 not only facilitates the insertion of the positioning column of the clamp, but also effectively limits the movement range of the clamp, ensuring that the double-sided adhesive body 1 can be centered on the cover plate of the touch screen. Since the double-sided adhesive body 1 can be centered, the appearance defects caused by offset are avoided, the overall aesthetics of the product is improved, and the adjustment time in the production process is reduced through precise positioning design, thereby improving production efficiency.

[0032] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0035] Embodiment 1 of the adhesive structure of the touch screen of the utility model

[0036] Please refer to Figure 1 The touch screen adhesive structure of the utility model includes: a double-sided adhesive body 1, a first positioning portion is arranged on the double-sided adhesive body 1, and the first positioning portion is located at two corners of the double-sided adhesive body 1, and is used to realize the positioning of the double-sided adhesive body 1 and the clamp, so as to realize the centering of the double-sided adhesive body 1;

[0037] The first positioning portion includes a first positioning circular hole 101 and a second positioning circular hole 102. The first positioning circular hole 101 and the second positioning circular hole 102 are respectively provided at two corners of the double-sided adhesive body 1, and the first positioning circular hole 101 and the second positioning circular hole 102 are diagonally arranged. By arranging the first positioning circular hole 101 and the second positioning circular hole 102 at two diagonally arranged corners of the double-sided adhesive body 1, accurate positioning points can be provided for the positioning column of the clamp. The design of the first positioning circular hole 101 and the second positioning circular hole 102 not only facilitates the insertion of the positioning column of the clamp, but also effectively limits the moving range of the clamp, ensuring that the double-sided adhesive body 1 can be centered on the cover plate of the touch screen. Since the double-sided adhesive body 1 can be centered, the appearance defects caused by offset are avoided, the overall aesthetics of the product is improved, and the adjustment time in the production process is reduced through precise positioning design, thereby improving production efficiency.

[0038] Further, such as Figure 1 As shown, the diameter of the first positioning circular hole 101 is smaller than the diameter of the second positioning circular hole 102. The main function of the first positioning circular hole 101 and the second positioning circular hole 102 is to provide an initial insertion point for the fixture positioning column. Due to the circular through hole design of the first positioning circular hole 101 and the second positioning circular hole 102, the positioning column can be easily inserted and initially fixed in position. In particular, the second positioning circular hole 102 is slightly larger than the first positioning circular hole 101. This design ensures that when the positioning column is inserted, there is a slightly loose initial position, which is conducive to subsequent precise positioning.

[0039] Further, such as Figure 1 As shown, second positioning parts are provided at the other two corners of the double-sided adhesive body 1, and the second positioning parts are used to realize the positioning of the double-sided adhesive body 1 and the clamp, so as to realize the centering of the double-sided adhesive body 1.

[0040] Further, such as Figure 1As shown, the second positioning portion includes a first positioning elliptical hole 103 and a second positioning elliptical hole 104. The first positioning elliptical hole 103 and the second positioning elliptical hole 104 are respectively opened at the other two corners of the double-sided adhesive body 1, and the first positioning elliptical hole 103 and the second positioning elliptical hole 104 are diagonally arranged.

[0041] Further, such as Figure 1 As shown, the first positioning oval hole 103 is arranged horizontally, and the second positioning oval hole 104 is arranged vertically. The design of the first positioning oval hole 103 takes into account that after the positioning post is inserted, fine adjustment needs to be made in one direction. The horizontal arrangement of the first positioning oval hole 103 allows the positioning post to move in the horizontal direction, thereby realizing precise adjustment of the horizontal position of the double-sided adhesive body 1 to ensure that it is centered in the horizontal direction;

[0042] The second positioning oval hole 104 is similar to the first positioning oval hole 103. The vertical setting of the second positioning oval hole 104 allows the positioning post to move in the vertical direction. In this way, after the horizontal position adjustment is completed, the vertical position of the double-sided adhesive body 1 can be further fine-tuned to ensure that it can also be centered in the vertical direction;

[0043] Through the above design, the solution proposed in this application can not only achieve the precise centering attachment of the double-sided adhesive body 1, but also is simple to operate and low-cost, greatly improving production efficiency and product quality. This innovative design concept and technical solution not only meets customers' high requirements for product quality, but also brings new breakthroughs in the production technology of touch screens.

[0044] Further, such as Figure 1 As shown, the lateral length of the second positioning oval hole 104 is the same as the diameter of the first positioning circular hole 101 , and the vertical length of the second positioning oval hole 104 is greater than the diameter of the first positioning circular hole 101 .

[0045] Further, such as Figure 1 As shown, the lateral length of the first positioning oval hole 103 is greater than the diameter of the first positioning circular hole 101 , and the vertical length of the first positioning oval hole 103 is the same as the diameter of the first positioning circular hole 101 .

[0046] Further, such as Figure 2 As shown, protective pieces are provided on both sides of the double-sided adhesive body 1, and the protective pieces are used to protect the double-sided adhesive body 1 before lamination, so as to reduce the influence of adverse external factors on the double-sided adhesive body 1 before lamination.

[0047] Further, such as Figure 2As shown, the protective part includes a protective film 2, which is adhered to the double-sided adhesive body 1. The protective film 2 is specifically a release film. The release film can prevent pollutants such as dust and impurities from adhering to the double-sided adhesive body 1, thereby ensuring the cleanliness and bonding quality of the double-sided adhesive body 1. The protective effect of the release film makes the double-sided adhesive body 1 not easily contaminated and damaged during storage and transportation, thereby ensuring the adhesive adhesion effect and product quality of the adhesive.

[0048] Further, such as Figure 2 As shown, a tear-off handle 201 is provided at one end of the protective film 2, and the tear-off handle 201 is used to assist in tearing off the protective film 2. Pulling the tear-off handle 201 can facilitate separation of the side of the protective film 2 close to the tear-off handle 201 from the double-sided adhesive body 1, thereby facilitating tearing off the protective film 2.

[0049] Align the positioning post of the fixture with the first positioning elliptical hole 103 of the touch screen adhesive, gently insert the positioning post, initially fix the position, then align the positioning post of the fixture with the first positioning elliptical hole 103, the second positioning elliptical hole 104 and the second positioning circular hole 102 in sequence, and gently insert the positioning post to ensure that the positioning post can move flexibly in the first positioning elliptical hole 103 and the second positioning elliptical hole 104. After all the positioning posts are inserted, gently adjust the fixture to make the positioning post slide to the appropriate position in the first positioning elliptical hole 103 and the second positioning elliptical hole 104 to achieve accurate centering of the double-sided adhesive body 1. After confirming that the double-sided adhesive body 1 has been centered, fit the double-sided adhesive body 1 on the touch screen cover plate, that is, Figure 3 shown.
