Description

Technical Field

[0001] The utility model relates to the technical field of laminating a cover plate and a sensor, and more specifically, to a curved surface structure of low-cost film lamination. Background Art

[0002] With the diversification and refinement of products, there are more and more small-sized products. In order to meet customer needs, there are more and more cylindrical small-curved projects such as smart pens. For such small-curved products (the following uses smart pen touch screen as an example), because the area is small and the smart pen is easy to operate, generally only a simple click or up, down, left, and right slide is required for touch control, without complex multi-touch, and usually requires a low price;

[0003] Because the appearance of products such as smart pens are all plastic curved tubes, the film touch sensor is usually directly attached to the customer's curved cover; but this requires special curved surface bonding equipment, otherwise it cannot be completed on the curved cover, but the cost of purchasing equipment is high, and the gains do not outweigh the losses when the project profit is low. On the other hand, affected by the curvature of the surface, if it is too curved, the film touch sensor may easily rebound and fall off. Therefore, we have made improvements to this and proposed a low-cost film bonding curved surface structure.

[0004] For example, a Chinese patent (publication number CN108615467B) discloses a bonding device and method for a special-shaped curved cover plate and a flexible screen. Its specification discloses that the bonding device of the prior art can only achieve bonding of 3D fixed curved cover plates; when the curved surface design of the cover plate tends to bend inward, that is, when the cover plate is a special-shaped curved cover plate, the existing bonding device cannot be used to achieve bonding. 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 when directly attaching the film touch sensor to the customer's curved cover plate, a special curved surface bonding device is required and the film touch sensor is too easy to rebound and fall off.

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

[0007] A low-cost film-bonded curved structure comprises: a curved cover plate body, a filling platform is arranged on one side of the curved cover plate body, and a side of the filling platform away from the curved cover plate body is horizontally arranged to achieve horizontal bonding with a film touch sensor.

[0008] As an improvement of the present invention, the horizontal plane of the filling platform is located inside the use direction.

[0009] As an improvement of the utility model, the side of the curved cover plate body close to the filling platform and the side away from the filling platform are both arc-shaped to adapt to cylindrical products.

[0010] As an improvement of the utility model, a protective plate is provided between the curved cover plate body and the filling platform.

[0011] As an improvement of the utility model, the protective plate is arranged in an arc shape to adapt to cylindrical products.

[0012] As an improvement of the present invention, the filling platform is arranged on the curved cover plate body by injection molding or injection.

[0013] As an improvement of the utility model, the surface of the protective plate is provided with an anti-slip texture to enhance the user's touch feel and stability.

[0014] As an improvement of the utility model, a protective coating is provided on the surface of the curved cover plate body to protect the curved cover plate body.

[0015] As an improvement of the present invention, a plurality of positioning marks are provided on a side of the filling platform away from the curved cover plate body, and the plurality of positioning marks are used for positioning the film touch sensor when it is attached.

[0016] As an improved manner of the present invention, the positioning mark is provided by silk screen printing.

[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 in the prior art that special curved surface bonding equipment is required when directly attaching the film touch sensor to the customer's curved cover plate and the film touch sensor is prone to rebound and fall off, the present application introduces the design of a filling platform. Since the side of the filling platform away from the curved cover plate body is horizontally set to achieve horizontal bonding with the film touch sensor, the film touch sensor can be smoothly bonded by ordinary equipment and process, without the need to purchase expensive special curved surface bonding equipment, which significantly reduces production costs. The horizontal surface design of the filling platform enables the film touch sensor to achieve stable bonding to maintain a good bonding effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Please refer to Figure 1-Figure 4 The low-cost curved surface structure of film bonding of the utility model comprises: a curved surface cover plate body 1, a filling platform 2 is arranged on one side of the curved surface cover plate body 1, and a side of the filling platform 2 away from the curved surface cover plate body 1 is horizontally arranged to achieve horizontal bonding with the film touch sensor; the present application introduces the design of the filling platform 2, because a side of the filling platform 2 away from the curved surface cover plate body 1 is horizontally arranged to achieve horizontal bonding with the film touch sensor, so that the flat bonding of the film touch sensor can be achieved by using ordinary equipment and technology, without the need to purchase expensive special curved surface bonding equipment, which significantly reduces the production cost; the horizontal surface design of the filling platform 2 enables the film touch sensor to achieve stable bonding to maintain a good bonding effect;

[0037] Furthermore, the horizontal plane of the filling platform 2 is located inside the use direction, thereby meeting the setting position of the film touch sensor.

[0038] Further, such as Figure 1-Figure 4As shown, the side of the curved cover plate body 1 close to the filling platform 2 and the side away from the filling platform 2 are both arc-shaped to adapt to the cylindrical product and facilitate adaptation to the shape of the cylindrical product.

[0039] Embodiment 2 of the utility model of low-cost film-bonded curved surface structure

[0040] Please refer to Figure 1-Figure 4 The low-cost curved surface structure of film bonding of the utility model comprises: a curved surface cover plate body 1, a filling platform 2 is arranged on one side of the curved surface cover plate body 1, and a side of the filling platform 2 away from the curved surface cover plate body 1 is horizontally arranged to achieve horizontal bonding with the film touch sensor; the present application introduces the design of the filling platform 2, because a side of the filling platform 2 away from the curved surface cover plate body 1 is horizontally arranged to achieve horizontal bonding with the film touch sensor, so that the flat bonding of the film touch sensor can be achieved by using ordinary equipment and technology, without the need to purchase expensive special curved surface bonding equipment, which significantly reduces the production cost; the horizontal surface design of the filling platform 2 enables the film touch sensor to achieve stable bonding to maintain a good bonding effect;

[0044] Further, such as Figure 1-Figure 4 As shown, the protective plate 3 is arranged in an arc shape to adapt to the cylindrical product and to facilitate adaptation to the shape of the cylindrical product.

[0045] Furthermore, the filling platform 2 is set on the curved cover plate body 1 by injection molding or injection. If the client shell is made of plastic, the filling platform 2 can be filled using the injection molding process. If the client shell is made of other materials, it can be filled by injection using glue. The glue can be polyurethane glue or silicone sealant. Polyurethane glue has excellent adhesion and wear resistance, and is suitable for bonding surfaces of various materials. Silicone sealant has good high temperature resistance, weather resistance and chemical corrosion resistance, and is suitable for application scenarios with higher requirements.

[0046] If the filling platform 2 is not provided and the film touch sensor is directly used for flat bonding, on the one hand, a hollow space will be formed between the film touch sensor and the curved cover body 1, which cannot be pressed flat and bonded with a roller; on the other hand, because there is an air layer between the curved cover body 1 and the film touch sensor, the film touch sensor cannot receive touch clicks on the curved cover body 1.

[0047] Furthermore, the surface of the protection plate 3 is provided with an anti-slip texture to enhance the user's touch feel and stability.

[0048] Embodiment 3 of the curved surface structure of low-cost film lamination of the utility model

[0050] Furthermore, the horizontal plane of the filling platform 2 is located inside the use direction, thereby meeting the setting position of the film touch sensor.

[0051] Further, such as Figure 1-Figure 4 As shown, the side of the curved cover plate body 1 close to the filling platform 2 and the side away from the filling platform 2 are both arc-shaped to adapt to the cylindrical product and facilitate adaptation to the shape of the cylindrical product.

[0053] Further, such as Figure 1-Figure 4 As shown, the protective plate 3 is arranged in an arc shape to adapt to the cylindrical product and to facilitate adaptation to the shape of the cylindrical product.

[0054] Furthermore, the filling platform 2 is set on the curved cover plate body 1 by injection molding or injection. If the client shell is made of plastic, the filling platform 2 can be filled using the injection molding process. If the client shell is made of other materials, it can be filled by injection using glue. The glue can be polyurethane glue or silicone sealant. Polyurethane glue has excellent adhesion and wear resistance, and is suitable for bonding surfaces of various materials. Silicone sealant has good high temperature resistance, weather resistance and chemical corrosion resistance, and is suitable for application scenarios with higher requirements.

[0055] If the filling platform 2 is not provided and the film touch sensor is directly used for flat bonding, on the one hand, a hollow space will be formed between the film touch sensor and the curved cover body 1, which cannot be pressed flat and bonded with a roller; on the other hand, because there is an air layer between the curved cover body 1 and the film touch sensor, the film touch sensor cannot receive touch clicks on the curved cover body 1.

[0056] Furthermore, the surface of the protection plate 3 is provided with an anti-slip texture to enhance the user's touch feel and stability.

[0058] The protective coating is one or more of AF coating, AR coating or AG coating;

[0059] AF coating is anti-fingerprint coating. AF coating is a surface treatment technology that forms a nano-level translucent coating on the surface of an object to resist the adhesion of fingerprints, oil stains and dust. AF coating has extremely low surface tension, making fingerprints and oil stains not easy to adhere and can be easily wiped off. AF coating has a smooth surface, feels comfortable and is not easy to scratch. AF coating has excellent optical properties and does not change the original texture. It has true wear resistance and effectively extends the service life of the object.

[0060] AR coating, or anti-reflective coating, is a dielectric thin film coating applied to optical surfaces; AR coating can effectively reduce the reflectivity of light within a specific wavelength range on the optical surface due to Fresnel reflection; by reducing the reflectivity, AR coating can significantly improve the clarity during observation or shooting; AG coating, or anti-glare coating, is a coating used to reduce light reflection and glare; AG coating scatters and reflects light, reduces light brightness, and thus avoids glare; AG coating can reduce glare and help improve visual comfort, especially in high-brightness environments.

[0061] Further, such as Figure 5 As shown, a plurality of positioning marks 4 are provided on a side of the filling platform 2 away from the curved cover plate body 1 , and the plurality of positioning marks 4 are used for positioning the film touch sensor when it is attached, thereby facilitating improving the accuracy of attaching the film touch sensor.

[0062] Further, such as Figure 5 As shown, the positioning mark 4 is set by silk screen printing. Silk screen printing refers to using a silk screen as a base plate and making a silk screen printing plate with graphics through a photosensitive platemaking method. During printing, the ink is squeezed onto the substrate through the mesh holes of the graphic part of the silk screen printing plate to form the same graphics as the original.
