Description

Technical Field

[0001] The utility model relates to the technical field of touch display screen modules, and more specifically, to an easily detachable touch display screen module structure. Background Art

[0002] With the advancement of technology and the improvement of consumers' requirements for the performance of electronic products, the application of touch screen modules is becoming more and more extensive. From smart phones, tablet computers to large display devices, they are inseparable from the support of touch screen modules. In order to ensure the stability and durability of these devices, the touch screen module has paid great attention to the connection and fixing method between it and the casing during the design and production process. When assembling traditional touch screen modules, in order to ensure its stability and reduce vibration noise, a circle of foam glue is usually added around its cover. This foam glue has excellent viscosity and cushioning properties, which can ensure that the touch screen module fits tightly on the casing, while absorbing and dispersing the stress caused by vibration, protecting the touch screen module from damage.

[0003] However, when the touch screen module has abnormalities and needs to be disassembled for repair, the design of this foam glue brings many inconveniences. Due to the strong adhesion of the foam glue, a lot of time and effort are required during the disassembly process, and even special tools or equipment are needed to separate the touch screen module from the casing. This not only increases the difficulty and cost of repair, but also easily causes damage to the device during the disassembly process, such as screen cracking, loose internal components, etc.; in addition, even if the touch screen module is successfully removed from the casing, the residual foam glue is also a problem that cannot be ignored. Due to the viscosity of the foam glue, it is easy to leave glue marks on the casing that are difficult to clean during the disassembly process, which not only affects the appearance of the device, but may also cause troubles in subsequent use and maintenance. Therefore, we have made improvements to this and proposed an easily disassembled touch screen module structure.

[0004] For example, a Chinese patent (publication number CN215494962U) discloses a foam glue frame sticker and display device for the production of touch screen frame stickers. Its specification discloses: The foam glue frame sticker used for the production of touch screen frame stickers is mainly used to connect the touch screen with the shell and the touch screen with the display screen during the production process of the touch screen frame sticker. The foam glue frame stickers currently used in the market for the production of touch screen frame stickers are of an integrated design. The advantage of this design is that it effectively reduces the production and assembly costs of the foam glue. However, due to its integrated design, when the assembly is poor and returned for after-sales repair, as long as it involves disassembling any one group of components between the touch screen and the front shell, or the touch screen and the display screen, the foam glue connecting the other group will also be damaged, making it difficult to disassemble the foam glue frame stickers used for the production of touch screen frame stickers. The above patents can prove the defects of the prior art. Utility Model Content

[0005] The technical problem to be solved by the embodiments of the present invention is that due to the strong adhesion of the foam glue, a lot of time and effort is required during the disassembly process, which can easily lead to damage to the equipment during the disassembly process and the problem of residual glue.

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

[0008] As an improved manner of the utility model, the thermal disassembly adhesive component is arranged in a frame shape, and the thermal disassembly adhesive component is used to realize the connection between the touch display screen module cover and the device housing.

[0009] As an improved manner of the utility model, the thermal disassembly adhesive assembly includes a substrate layer, a first adhesive layer is provided on a side of the substrate layer close to the device housing, and the first adhesive layer is connected to the device housing.

[0010] As an improved manner of the utility model, a second adhesive layer is provided on a side of the substrate layer close to the touch display module cover plate, and the second adhesive layer is connected to the touch display module cover plate.

[0011] As an improved manner of the present invention, the first adhesive layer is a heat-disassembly pressure-sensitive adhesive layer, and two sides of the heat-disassembly pressure-sensitive adhesive layer are respectively connected to the substrate layer and the device housing.

[0012] As an improvement of the utility model, the viscosity of the heat-disassembly pressure-sensitive adhesive layer decreases under heating.

[0013] As an improved manner of the utility model, the substrate layer is a foam substrate, and the foam substrate is connected to a side of the heat-disassembly pressure-sensitive adhesive layer away from the device housing.

[0014] As an improvement of the present invention, the second adhesive layer is a high-performance pressure-sensitive adhesive layer, and the high-performance pressure-sensitive adhesive layer is connected to a side of the foam substrate away from the heat-disassembly pressure-sensitive adhesive layer.

[0015] As an improved manner of the utility model, a side of the high-performance pressure-sensitive adhesive layer away from the foam substrate is connected to a touch display screen module cover.

[0016] Compared with the prior art, the embodiments of the present invention mainly have the following beneficial effects:

[0017] In order to solve the problem in the prior art that the foam glue has strong adhesion, a lot of time and effort are required during the disassembly process, which easily leads to damage to the device and residual glue during the disassembly process, the present application provides a thermal disassembly adhesive component. The thermal disassembly adhesive component has sufficient adhesion under normal conditions to ensure the connection between the touch display module cover and the device shell, and the adhesion of the thermal disassembly adhesive component and the device shell bonding surface decreases under heating. Therefore, when disassembly and repair are required, only the bonding side of the thermal disassembly adhesive component and the device shell needs to be heated, and the adhesion of the thermal disassembly adhesive component and the device shell bonding surface will be reduced, thereby facilitating the disassembly of the touch display module cover and the device shell. This design not only reduces the difficulty of rework and improves the success rate of rework, but also reduces the risk of equipment damage and residual glue on the casing, providing users with a more convenient and reliable maintenance experience.

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.

[0024] As described in the background art, when the touch screen module has a defect or abnormality and needs to be disassembled for repair, the design of this foam glue brings many inconveniences. Due to the strong adhesion of the foam glue, a lot of time and energy are required during the disassembly process, and even special tools or equipment are required to separate the touch screen module from the casing, which not only increases the difficulty and cost of repair, but also easily causes damage to the device during the disassembly process, such as screen cracking, loose internal components, etc.; in addition, even if the touch screen module is successfully disassembled from the casing, the residual foam glue is also a problem that cannot be ignored. Due to the viscosity of the foam glue, it is easy to leave glue marks on the casing that are difficult to clean during the disassembly process, which not only affects the appearance of the device, but may also cause trouble for subsequent use and maintenance.

[0025] In order to solve this technical problem, the utility model provides an easily detachable touch display screen module structure.

[0026] Specifically, please refer to Figure 1-Figure 3 The easily disassembled touch display module structure specifically includes:

[0027] A touch display module cover plate 2 and a device housing 3, a thermal disassembly adhesive component 1 is bonded between the touch display module cover plate 2 and the device housing 3, and the viscosity of the bonding surface of the thermal disassembly adhesive component 1 and the device housing 3 is reduced under heating.

[0028] The utility model provides an easily disassembled touch display module structure. The utility model provides a heat-disassembly adhesive component 1. The heat-disassembly adhesive component 1 has sufficient viscosity under normal conditions to ensure the connection between the touch display module cover plate 2 and the device shell 3. The viscosity of the bonding surface of the heat-disassembly adhesive component 1 and the device shell 3 decreases under heating. Therefore, when disassembly and repair are required, only one side of the heat-disassembly adhesive component 1 and the device shell 3 needs to be heated, and the viscosity of the bonding surface of the heat-disassembly adhesive component 1 and the device shell 3 will be reduced, thereby facilitating the disassembly of the touch display module cover plate 2 and the device shell 3. This design not only reduces the difficulty of repair and improves the success rate of repair, but also reduces the risk of equipment damage and glue residue on the casing, providing users with a more convenient and reliable maintenance experience.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] Embodiment 1 of the easily disassembled touch screen module structure of the utility model

[0033] Please refer to Figure 1-Figure 3 The easily disassembled touch display module structure of the utility model comprises: a touch display module cover plate 2 and a device housing 3, a heat disassembly adhesive component 1 is bonded between the touch display module cover plate 2 and the device housing 3, the adhesiveness of the heat disassembly adhesive component 1 and the bonding surface of the device housing 3 is reduced under the heat state, and the heat disassembly adhesive component 1 is provided by the utility model, and the heat disassembly adhesive component 1 has sufficient adhesiveness under normal conditions, so as to ensure the connection between the touch display module cover plate 2 and the device housing 3, and the heat disassembly adhesive component 1 The viscosity of the bonding surface with the device shell 3 decreases when heated. Therefore, when disassembly and repair is required, it is only necessary to heat the side of the thermal disassembly adhesive component 1 that is bonded to the device shell 3. The viscosity of the bonding surface of the thermal disassembly adhesive component 1 and the device shell 3 will decrease, thereby facilitating the disassembly of the touch display module cover 2 and the device shell 3. This design not only reduces the difficulty of repair and improves the success rate of repair, but also reduces the risk of equipment damage and residual glue on the casing, providing users with a more convenient and reliable maintenance experience.

[0034] Further, such as Figure 2-Figure 3 As shown, the thermal disassembly adhesive component 1 is arranged in a frame shape, and the thermal disassembly adhesive component 1 is used to realize the connection between the touch display module cover plate 2 and the device housing 3. The frame shape is adopted, so that after the touch display module cover plate 2 and the device housing 3 are connected through the thermal disassembly adhesive component 1, the thermal disassembly adhesive component 1 can seal the connection between the touch display module cover plate 2 and the device housing 3, thereby improving the protection level of the touch display module cover plate 2 and the device housing 3.

[0035] Embodiment 2 of the easily disassembled touch screen module structure of the utility model

[0036] The easily disassembled touch screen module structure of the utility model is further as follows: Figure 1 As shown, the thermal disassembly adhesive assembly 1 includes a substrate layer, a first adhesive layer is provided on one side of the substrate layer close to the device housing 3, and the first adhesive layer is connected to the device housing 3. The thermal disassembly adhesive assembly 1 can be connected to the device housing 3 through the first adhesive layer.

[0037] Further, such as Figure 1As shown, a second adhesive layer is provided on one side of the substrate layer close to the touch display module cover plate 2, and the second adhesive layer is connected to the touch display module cover plate 2. The connection between the thermally disassembled adhesive component 1 and the touch display module cover plate 2 can be achieved through the first adhesive layer.

[0038] Further, such as Figure 1 As shown, the first adhesive layer is a heat-disassembly pressure-sensitive adhesive layer 103 , and the two sides of the heat-disassembly pressure-sensitive adhesive layer 103 are connected to the substrate layer and the device housing 3 respectively.

[0039] Furthermore, the viscosity of the heat-disassembly pressure-sensitive adhesive layer 103 decreases when heated. This arrangement makes it easy to disassemble the touch display module cover 2 and the device housing 3 during maintenance. This design not only reduces the difficulty of rework and improves the success rate of rework, but also reduces the risk of equipment damage and residual glue on the housing, providing users with a more convenient and reliable maintenance experience.

[0040] Further, such as Figure 1 As shown, the substrate layer is a foam substrate 102, and the foam substrate 102 is connected to the side of the heat-disassembly pressure-sensitive adhesive layer 103 away from the device housing 3, and the foam substrate 102 provides a carrier for the heat-disassembly pressure-sensitive adhesive layer 103 and the second adhesive layer;

[0041] The foam substrate 102 serves as the middle layer of the heat-disassembly adhesive component 1, and mainly plays the role of buffering and supporting. It is made of a lightweight and soft foam material, has excellent physical properties and chemical stability, can effectively protect the touch screen module, and provide stable support when needed; the foam has good buffering performance, can absorb and disperse the impact force from the outside, and protect the touch screen module from damage. When the electronic device is subjected to external forces such as vibration and impact, the foam can effectively reduce the impact of these forces on the touch screen module, ensuring the stable operation of the device; the foam also has a certain supporting effect, and can maintain the stable position of the touch screen module cover plate 2 in the housing. Through the support of the foam, the touch screen module cover plate 2 can be tightly fitted on the device housing 3, reducing equipment failures caused by looseness or displacement;

[0042] Foam is usually made of polyurethane PU or other similar lightweight foam materials. These materials have excellent elasticity, wear resistance and corrosion resistance, and can adapt to various complex working environments.

[0043] Embodiment 3 of the easily disassembled touch screen module structure of the utility model

[0044] The easily disassembled touch screen module structure of the utility model is further as follows: Figure 1As shown, the second adhesive layer is a high-performance pressure-sensitive adhesive layer 101 , and the high-performance pressure-sensitive adhesive layer 101 is connected to a surface of the foam substrate 102 away from the heat-disassembly pressure-sensitive adhesive layer 103 .

[0045] Further, such as Figure 1 As shown, the side of the high-performance pressure-sensitive adhesive layer 101 away from the foam substrate 102 is connected to the touch display module cover plate 2. The high-performance pressure-sensitive adhesive layer 101 adopts a pressure-sensitive adhesive composed of polymer materials, adhesives, fillers, etc. with excellent performance. This pressure-sensitive adhesive is usually called high-performance pressure-sensitive adhesive (HPA). The high-performance pressure-sensitive adhesive can form a strong bond with the adherend. Under slight applied pressure, the high-performance pressure-sensitive adhesive can quickly contact the adherend and produce a strong bonding effect; the high-performance pressure-sensitive adhesive itself has high strength and can maintain a stable bonding effect for a long time, and it is not easy for the adhesive layer to fall off or be damaged; the high-performance pressure-sensitive adhesive has a certain elasticity and can adapt to touch display module cover plates 2 of different shapes and sizes to ensure that the touch display module can fit tightly on the casing; the high-performance pressure-sensitive adhesive is usually applied by processes such as scraping, spraying or rolling.

[0046] Thermal disassembly pressure-sensitive adhesive is an existing technology. The main characteristic of thermal disassembly pressure-sensitive adhesive lies in its unique thermal disassembly performance, that is, at a specific temperature, its viscosity will be significantly reduced, making it convenient to remove the touch display module cover 2 from the device housing 3; at room temperature, the thermal disassembly pressure-sensitive adhesive maintains sufficient initial viscosity to ensure that the touch display module can be stably adhered to the housing to prevent loosening or falling off.

[0047] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model 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 utility model more thorough and comprehensive. Although the utility model is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to replace some of the technical features therein with equivalents. Any equivalent structure made using the contents of the utility model specification and the accompanying drawings, directly or indirectly used in other related technical fields, is also within the scope of patent protection of the utility model.
