Description

Technical Field

[0001] This utility model relates to the field of e-reader display technology, specifically to a glass panel structure with writing feel and UV blocking function, and an adhesive coating fixture. Background Technology

[0002] An e-reader is a paper-like reader, short for electronic reader. It specifically refers to electronic reading products that use E-ink display technology to provide a paper-like reading experience.

[0003] To meet the demands of deep interaction, e-books need to provide a writing feel. When the screen receives handwriting input, it should simulate the resistance feedback of writing on paper. The core goal is to allow users to experience a natural writing experience on electronic devices that closely resembles that of pen and paper. Currently, a common approach is to add a frosted layer to the surface of the e-paper to simulate the friction of paper, reduce pen slippage, and enhance the "damping feel." The frosted layer on the glass panel of e-books is generally created using a chemical etching process. However, the size of the microstructure pits produced by the etching process is affected by various process parameters, which can lead to inconsistencies in the writing damping feel of different batches of glass panels. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a glass panel structure with writing feel and UV blocking function.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: a glass panel structure with writing feel and UV blocking function, including a tempered glass layer and a UV adhesive layer covering the outer surface of the tempered glass layer, the upper surface of the UV adhesive layer having an alternating concave and convex microstructure texture, the depth of the microstructure texture being 3μm to 35μm, and the distance between the outer contour of the UV adhesive layer and the outer contour of the tempered glass layer being no more than 0.2mm.

[0006] This invention simulates the writing resistance of paper by setting a UV adhesive layer with a specific microstructure texture on the outer surface of the tempered glass layer. Compared with traditional chemical etching processes, the microstructure texture of the UV adhesive layer can be precisely controlled by the mold, effectively ensuring the consistency of writing resistance between different batches of products. The depth of the microstructure texture is controlled within the range of 3μm to 35μm, which ensures sufficient writing resistance feedback while avoiding writing jams caused by excessively deep textures or slippage caused by excessively shallow textures, thus improving writing comfort. After the UV adhesive layer cures, it forms a dense cross-linked network structure, which can effectively block the ultraviolet light generated during the operation of the e-reader's light source module, preventing ultraviolet light from penetrating the adhesive layer and directly hitting the eyes, reducing eye irritation and visual fatigue during reading.

[0007] Furthermore, the surface hardness of the tempered glass layer reaches 750g load 3H or higher.

[0008] By adopting the above-mentioned preferred solution, the glass panel can be given good scratch resistance, effectively resisting friction damage from pen tips or hard objects in daily use, and extending the service life of the glass panel.

[0009] Furthermore, the thickness of the tempered glass layer is 0.2mm-5.0mm.

[0010] Using the above-mentioned preferred solution, a minimum thickness of 0.2mm can meet the design requirements of e-reader devices for lightweight and thinness, avoiding an increase in the overall size and weight of the device; while a maximum thickness of 5.0mm can ensure that the glass panel has sufficient support to prevent breakage or bending during installation and use, and adapt to the design requirements of e-reader products of different sizes and usage scenarios.

[0011] Furthermore, the microstructure texture is a regularly arranged convex ridge texture.

[0012] Using the preferred scheme described above, the raised texture can create uniform and stable writing resistance.

[0013] Furthermore, the microstructure texture is a regularly arranged pit texture.

[0014] By adopting the above-mentioned preferred solution, the recessed structure can ensure the damping feel while creating a certain diffuse reflection effect on the surface of the UV adhesive layer, reducing screen glare and improving the reading comfort of the e-reader.

[0015] A coating fixture for molding and curing UV adhesive layers on tempered glass surfaces, including: A base, wherein the base is provided with positioning blocks for positioning the outline of the tempered glass layer; The light-blocking ring is located on the outer side of the tempered glass layer; An excess adhesive washer is disposed on the upper surface of the light-blocking ring, and the excess adhesive washer is located on the outer side of the tempered glass layer. The upper cover plate includes an outer cover plate and a light-transmitting cover plate. The light-transmitting cover plate is located in the middle of the outer cover plate. The planar dimensions of the light-transmitting cover plate match the surface dimensions of the tempered glass layer. The bottom surface of the light-transmitting cover plate is provided with microstructure texture. A positioning structure is provided between the outer cover plate and the base so that the light-transmitting cover plate and the tempered glass layer are vertically aligned.

[0016] This utility model's adhesive application fixture achieves precise positioning of the tempered glass layer via positioning blocks on the base, ensuring accurate UV adhesive application. A light-blocking ring prevents external stray light interference during UV curing, guaranteeing uniform curing results. An overflow gasket collects excess UV adhesive during application, preventing spillage and contamination of equipment or product edges, thus improving product appearance. The light-transmitting cover plate of the upper cover is aligned vertically with the tempered glass layer and matches its dimensions, allowing for precise replication of the microstructure texture from the bottom of the cover plate onto the UV adhesive layer surface. This enables standardized production of the microstructure texture, while the light-transmitting cover plate facilitates UV light penetration, ensuring full curing of the UV adhesive and enhancing the bonding strength between the UV adhesive layer and the tempered glass layer. The UV adhesive layer uses a transparent optical adhesive with high UV blocking properties. After curing, the adhesive layer forms a dense cross-linked network structure, effectively blocking ultraviolet light generated during the operation of the e-reader's light source module, preventing UV light from penetrating the adhesive layer and directly hitting the eyes, reducing eye strain and visual fatigue during reading.

[0017] Furthermore, a handle is provided on the outer cover plate.

[0018] The above-mentioned preferred solution allows operators to quickly and conveniently pick up and put down the top cover.

[0019] Furthermore, the positioning structure includes a positioning hole on the base and a positioning shaft on the lower surface of the outer cover plate, wherein the positioning shaft matches the positioning hole.

[0020] By adopting the above-mentioned preferred solution, the matching structure of the positioning shaft and the positioning hole can realize the rapid and accurate positioning of the upper cover plate and the base, ensuring that the light-transmitting cover plate and the tempered glass layer are aligned vertically.

[0021] Furthermore, the head end of the positioning shaft is provided with a guide arc surface.

[0022] The preferred solution described above can serve as a guide during the insertion of the positioning shaft into the positioning hole, reducing the difficulty of aligning the positioning shaft and the positioning hole. Attached Figure Description
