Description

Technical Field

[0001] The utility model relates to the technical field of double-sided adhesive, and more specifically to a splicing double-sided adhesive structure. Background Art

[0002] In the manufacturing process of the cover module structure, especially when it comes to the application scenario that requires sticking double-sided adhesive materials on the back of the cover, the traditional method is to use a single double-sided adhesive foam sponge or double-sided adhesive foam glue as the incoming material. Although this single-strip incoming material method can control the material cost to a certain extent, because it can be cut according to the actual required length, reducing unnecessary waste, but the disadvantages of this method are gradually emerging;

[0003] After the single double-sided adhesive strip is produced by the manufacturer, it is purchased by the client for use. When the single double-sided adhesive strip arrives at the client for use, the client's workers need to manually attach it to the back of the cover plate one by one, which not only increases the workload of the workers, but also makes it difficult to ensure the accuracy and consistency of the attachment by manual operation, and affects the quality of the client's use and production efficiency. Therefore, we have made improvements to this and proposed a double-sided adhesive structure.

[0004] For example, a Chinese patent (publication number CN211454017U) discloses a mobile phone backlight module, including a light guide plate, a frame surrounding the light guide plate, a diffusion sheet, a lower light enhancement film and an upper light enhancement film stacked in sequence above the light guide plate, a reflective sheet is arranged below the light guide plate, and light guide dots are arranged on the bottom surface of the light guide plate, wherein the left edge and the right edge of the bottom surface of the light guide plate are both provided with transparent double-sided adhesive strips, and the reflective sheet is bonded to the light guide plate through the transparent double-sided adhesive strips. Utility Model Content

[0007] A spliced ​​double-sided adhesive structure comprises a double-sided adhesive body, which is arranged in a frame shape and is formed by splicing two first double-sided adhesive strips and two second double-sided adhesive strips to achieve one-time attachment of the double-sided adhesive body.

[0008] As an improved manner of the present invention, the two first double-sided adhesive strips are arranged in parallel, the two second double-sided adhesive strips are arranged in parallel, and the first double-sided adhesive strip and the second double-sided adhesive strip are arranged perpendicularly.

[0009] As an improvement of the present invention, an alignment piece is provided between the second double-sided adhesive strip and the first double-sided adhesive strip, and the alignment piece is used for alignment when the second double-sided adhesive strip is attached to the first double-sided adhesive strip.

[0010] As an improvement of the utility model, the alignment piece includes an alignment groove opened at one end of the second double-sided adhesive strip near the first double-sided adhesive strip, and the end of the first double-sided adhesive strip near the second double-sided adhesive strip is fixedly connected to a third double-sided adhesive strip, and the third double-sided adhesive strip is plugged into the alignment groove; a gap is left between the third double-sided adhesive strip and the alignment groove to allow air to be discharged when the double-sided adhesive bodies are bonded.

[0011] As an improved manner of the utility model, a first protective portion is provided on one side of the double-sided adhesive body, and the first protective portion is used for protecting one side of the double-sided adhesive body.

[0012] As an improved manner of the utility model, the first protective portion includes an upper release film, and the upper release film is attached between one side of the first double-sided adhesive strip and the second double-sided adhesive strip.

[0013] As an improved manner of the utility model, a tearing handle is fixedly connected to one side of the upper release film, and the tearing handle is used to assist in tearing off the upper release film.

[0014] As an improved manner of the utility model, a second protective portion is provided on the other side of the double-sided adhesive body, and the second protective portion is used for protecting the other side of the double-sided adhesive body.

[0015] As an improved manner of the present invention, the second protective portion is a lower release film, and the lower release film is attached to the first double-sided adhesive strip and the second double-sided adhesive strip on a surface away from the upper release film.

[0016] As an improvement of the utility model, a dotted line is provided at a corner of the lower release film near the tear-off handle, and a gasket is fixedly connected between the tear-off handle and the lower release film, and the gasket is located at the corner of the lower release film.

[0017] Compared with the prior art, the embodiments of the present invention mainly have the following beneficial effects:

[0018] In order to solve the problem of increasing the workload and labor cost of workers by using a single double-sided adhesive foam sponge or double-sided adhesive foam glue as incoming materials in the prior art, the present application provides a double-sided adhesive body, which is frame-shaped and is composed of two first double-sided adhesive strips and two second double-sided adhesive strips. When the double-sided adhesive body arrives at the client from the manufacturer, the client can directly paste the double-sided adhesive body at one time, that is, the entire double-sided adhesive body can be pasted to the back of the cover plate at one time without manual operation one by one, thereby greatly improving the bonding efficiency.
