Description

Technical Field

[0001] The utility model relates to the technical field of film pasting, in particular to a double-sided adhesive and sponge integrated structure. Background Art

[0002] At present, many of the cover viewing areas of vehicle-mounted touch screens or display screens have sticky sponges, which act as frame adhesives, while the ink areas around the edges have double-sided adhesives, which adhere to the client shell and play a structural fixing role. Usually, the sticky sponges and double-sided adhesives are separately supplied, and are separated and attached twice with a fixture. This assembly process is long and inefficient, with a high probability of comprehensive attachment deviation and low yield. A more optimized structure is needed to improve this process defect.

[0003] For example, a Chinese utility model patent (CN 217674395 U) discloses a circular protective film, which belongs to the field of protective film technology. A circular protective film comprises: a film paper, the bottom surface of which is pasted on the surface of the part to be protected by glue; a film tearing component is provided on the upper surface of the film paper, and the film tearing component is used to tear off the film paper; the film paper is provided with two grooves, and the two grooves are symmetrically arranged on both sides of the film tearing component. The utility model solves the problem that the protective film is difficult to tear off due to the atmospheric pressure after being left for a long time.

[0004] However, when the present inventor implemented this device, he found the following defects: the incoming materials were separated and then assembled twice with a clamp. This assembly process was long and inefficient, with a high probability of misalignment and a low yield. A more optimized structure was needed to improve this process defect. Utility Model Content

[0034] 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 accompanying drawings.

The thickness of the double-sided sticky sponge 2 is preferably the same as the first sticky layer 1, and can also be a combination with a thickness difference within the range of 0.5 mm. Since the sticky sponge 2 is compressible, even if the second sticky layer 3 is not compressible, as long as the sticky sponge 2 is thicker than the second sticky layer 3, when pasted on the same plane, the sticky sponge 2 can be compressed first and then attached to the same plane with the second sticky layer 3 at the same time.

[0045] Through the above structural design, the panels are simultaneously assembled on a PET film layer 7, and positioning holes 8 are set on the PET film layer 7. The production line relies on the positioning holes 8 to assemble the integrated structure, which can achieve high-precision positioning and installation, ensure the attachment yield, directly eliminate the occurrence of undesirable conditions such as skewed attachment, and cancel the cost of auxiliary fixtures, saving a film attaching position, optimizing the film attaching process, and improving the film attaching efficiency and yield, thereby improving product competitiveness.

The technique is simple and the installation accuracy is high, and the efficiency and yield are high. The positioning holes 8 are set at the four corners of the PET film layer 7. Under different circumstances, there can be other numbers of positioning holes 8, not limited to four. The shape of the PET film layer 7 can also be circular, not limited to the shape, and is not limited here.

[0050] Specifically, the thickness of the first adhesive layer 1 is 10 mm to 12 mm.

[0051] Through the above structural design, in this embodiment, the thickness of the first adhesive layer 1 is 10 mm. By integrating the outer double-sided adhesive and the visual area sponge together, and simultaneously splicing them on a PET film, and making positioning holes 8 on the PET film, the production line relies on the positioning holes 8 to assemble the integrated structure, which can achieve high-precision positioning and installation, ensure the attachment yield, directly eliminate the occurrence of undesirable conditions such as skewed attachment, and cancel the cost of auxiliary fixtures, saving a film sticking position, optimizing the film sticking process, and improving the film sticking efficiency and yield, thereby improving product competitiveness.
