Description

Technical Field

[0001] This utility model relates to the field of protective film technology, and in particular to a protective film for a module camera and an electronic device. Background Technology

[0002] Camera protective films, as common protective accessories, are widely used in module products. During transportation, they need to be kept in place to prevent dirt from getting on the camera module. However, due to factors such as strong adhesion and prolonged adhesion to the module, camera protective films are difficult to peel off the module surface. Even after peeling, residue remains, which can easily affect customer experience and some camera functions. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a protective film for a module camera and an electronic device, which aims to solve the technical problems mentioned in the background art.

[0004] A protective film for a module camera includes a protective film layer, an adhesive layer assembly, and a tear-away layer. The adhesive layer assembly includes a first adhesive layer and a second adhesive layer stacked together. The top surface of the first adhesive layer is attached to the protective film layer, a portion of the bottom surface of the first adhesive layer is attached to the second adhesive layer, and the side of the second adhesive layer facing away from the first adhesive layer is attached to the module. The first adhesive layer has a first clearance hole, and the second adhesive layer has a second clearance hole. The positions of the first clearance hole and the second clearance hole correspond to each other. The first clearance hole and the second clearance hole are used to accommodate the camera of the module. The tear-away layer is located between a portion of the first adhesive layer and the module. One end of the tear-away layer is fixed inside the second adhesive layer, and the other end of the tear-away layer protrudes outside the first adhesive layer.

[0005] The beneficial effects of this utility model are:

[0006] The layered structure of the double adhesive layer (first adhesive layer and second adhesive layer) ensures both bonding strength and buffers external impact forces. When the adhesive layer assembly is bonded to the module, the edges of the first and second vent holes restrict the flow of adhesive, preventing the adhesive layer from overflowing into the module's camera under high temperature or pressure. The protective film layer isolates and protects the module's camera. The protruding end of the tear-off layer extending beyond the first adhesive layer provides an operating handle, allowing users to quickly peel off the protective film without tools. During the peeling process, the tear-off layer preferentially triggers the cohesive failure of the second adhesive layer through the interface stress concentration effect, and then the entire detachment is achieved through the adhesion between the first adhesive layer and the protective film layer, thus preventing adhesive residue from remaining on the module surface.

[0007] Furthermore, one end of the second adhesive layer is recessed to form a receiving cavity, and the end of the tear-off layer protrudes toward the receiving cavity to form an extension, and the receiving cavity and the extension are adapted to each other.

[0008] Furthermore, a plurality of viscous micropillars are uniformly distributed on the side of the second adhesive layer facing away from the first adhesive layer.

[0009] Furthermore, the thickness of the second adhesive layer is the same as the thickness of the tear-off layer.

[0010] Furthermore, anti-slip stripes are evenly distributed on both sides of the tear-away layer at the end away from the extension.

[0011] Furthermore, the protective film layer has a lifting portion on the side facing away from the first adhesive layer.

[0012] Furthermore, the protective film layer is made of transparent PET.

[0013] This invention also provides an electronic device, including the module camera protective film as described above. Attached Figure Description

[0021] A protective film for a module camera, such as Figure 1 As shown, it includes a protective film layer 1, an adhesive layer assembly 2, and a tear-off layer 3.

[0022] Specifically, such as Figures 1 to 3 As shown, the adhesive layer assembly 2 includes a first adhesive layer 21 and a second adhesive layer 22 stacked together. The top surface of the first adhesive layer 21 is attached to the protective film layer 1, a portion of the bottom surface of the first adhesive layer 21 is attached to the second adhesive layer 22, and the side of the second adhesive layer 22 facing away from the first adhesive layer 21 is attached to the module. The first adhesive layer 21 is provided with a first clearance hole (not shown), and the second adhesive layer 22 is provided with a second clearance hole 221. The positions of the first clearance hole and the second clearance hole 221 correspond. The first clearance hole and the second clearance hole 221 are used to accommodate the camera of the module. The tear-off layer 3 is located between a portion of the first adhesive layer 21 and the module. One end of the tear-off layer 3 is fixed inside the second adhesive layer 22, and the other end of the tear-off layer 3 protrudes outside the first adhesive layer 21. The layered structure of the double adhesive layers (first adhesive layer 21 and second adhesive layer 22) ensures both bonding strength and buffers external impact forces. When the adhesive layer assembly 2 is bonded to the module, the edges of the first and second vent holes 221 restrict the flow of adhesive, preventing the adhesive layer from overflowing into the module's camera under high temperature or pressure. The protective film layer 1 isolates and protects the module's camera. The protruding end of the tear-off layer 3 extending beyond the first adhesive layer 21 provides an operating handle, allowing users to quickly peel off the protective film without tools. During the peeling process, because one end of the tear-off layer 3 is fixed inside the second adhesive layer 22, the tear-off layer 3 preferentially triggers the cohesive failure of the second adhesive layer 22 through the interface stress concentration effect. Subsequently, the entire assembly is detached through the bonding transfer between the first adhesive layer 21 and the protective film layer 1, thus preventing adhesive residue from remaining on the module surface.

[0023] Specifically, one end of the second adhesive layer 22 is recessed to form a receiving cavity 222, and the end of the tear-away layer 3 facing the receiving cavity 222 protrudes to form an extension 31. The receiving cavity 222 and the extension 31 are adapted to each other. By using the extension 31 in the receiving cavity, the contact area between the tear-away layer 3 and the second adhesive layer 22 is increased, making the two structures approximately a single unit. During the peeling process, the tear-away layer 3 can completely peel the second adhesive layer 22 from the module.

[0024] Specifically, multiple adhesive micropillars 223 are evenly distributed on the side of the second adhesive layer 22 facing away from the first adhesive layer 21. By setting the adhesive micropillars 223, while ensuring that the second adhesive layer 22 adheres to the module, the contact area and viscosity between the second adhesive layer 22 and the module are reduced, so that the second adhesive layer 22 can be more completely peeled off from the module during the peeling process.

[0025] It is understandable that the second adhesive layer 22 is low viscosity when it is peeled and attached to the module, and high viscosity when it is attached to the first adhesive layer 21, fixed to the hand-tearable layer 3, and attached to the protective film layer 1.

[0026] Specifically, the thickness of the second adhesive layer 22 is the same as the thickness of the tear-off layer 3. This results in a larger cross-sectional area where the second adhesive layer 2 and the tear-off layer 3 come into contact. The consistent thickness also helps to evenly distribute stress during peeling, avoiding uneven tearing caused by localized stress concentration.

[0027] Specifically, anti-slip stripes 32 are evenly distributed on both opposite sides of the end of the tear-away layer 3 furthest from the extension. As the peeling end, the anti-slip stripes 32 in the tear-away layer 3 prevent fingers from slipping during operation, increasing operational reliability.

[0028] Specifically, the protective film layer 1 has a lifting part 11 on the side facing away from the first adhesive layer 21. During application, the lifting part 11 is used to precisely align the protective film of the module camera with the module and then press it firmly; during peeling, the lifting part 11 is used in conjunction with the tear-off layer 3 to better peel the second adhesive layer 22 from the module.

[0029] Specifically, the protective film layer 1 is made of transparent PET. As a transparent PET layer, it can resist dust and prevent static electricity from damaging the module's camera.

[0030] This invention utilizes a layered structure of two adhesive layers (first adhesive layer 21 and second adhesive layer 22) to ensure bonding strength while also buffering external impact forces. When the adhesive layer assembly 2 is bonded to the module, the edges of the first and second clearance holes 221 restrict adhesive flow, preventing the adhesive layer from overflowing into the module's camera under high temperature or pressure. A protective film layer 1 isolates and protects the module's camera. The tear-off layer 3 extends to the protruding end of the first adhesive layer 21, providing an operating handle and featuring anti-slip stripes 32, allowing users to operate without tools. The protective film can be quickly peeled off. During the peeling process, the extension 31 is provided in the receiving cavity 222 to increase the contact area between the tear-off layer 3 and the second adhesive layer 22, making the two structures approximately a whole. The tear-off layer 3 preferentially causes the cohesive failure of the second adhesive layer 22 through the interface stress concentration effect, so that the tear-off layer 3 can completely peel the second adhesive layer 22 off from the module. Then the second adhesive layer 22 drives the first adhesive layer 21, and the whole separation is achieved through the adhesion transfer between the first adhesive layer 21 and the protective film layer 1, so as to avoid the adhesive layer remaining on the module surface.

[0031] This invention also provides an electronic device, including the module camera protective film as described above.
