[0002] In the consumer electronics field, the cover glass of mobile devices such as mobile phones is an important component, and its performance, texture, and appearance design directly affect user experience and product competitiveness. Currently, most mainstream mobile phone battery covers and other covers on the market are made of composite materials (such as fiberglass, PC+PMMA, etc.) or single glass materials.

[0003] While composite material covers have certain advantages in terms of cost and processing difficulty, they generally suffer from poor texture and cannot achieve the high-end, exquisite visual and tactile experience of glass. They also fail to meet consumers' ever-increasing demands for product appearance quality. Furthermore, composite material covers have significant limitations in terms of functional integration, making it difficult to achieve a variety of textures and colors and thus failing to meet users' personalized aesthetic needs. Summary of the Invention

[0004] In order to solve the technical problems existing in the background art, the present invention proposes a cover plate, a cover plate processing equipment and a processing method thereof.

[0007] Functional components are embedded in the precast groove.

[0008] The packaging component is mounted on the substrate and can cover the prefabricated cavity and functional components.

[0009] Preferably, the substrate is made of fiberglass board with a thickness of 0.2–0.4 mm.

[0010] Preferably, the functional components include at least one of the following: heat dissipation material, antenna, wireless charging module, and magnetic coil.

Attached Figure Description

[0023] Figure 2 This is a side view of the substrate, functional components, and packaging components of the present invention. Detailed Implementation

[0024] refer to Figure 1-2This invention proposes a cover plate for use as a mobile phone back cover, comprising: a substrate, which serves as the basic structure of the cover plate and plays a crucial role in supporting and bearing other components. In this design, the substrate is preferably made of fiberglass board 1, with its thickness controlled within the range of 0.2–0.4 mm. This thickness selection has been carefully considered. If the thickness is too thin, the substrate will lack sufficient strength and will be unable to withstand various external forces during subsequent processing and use, while also failing to provide sufficient embedding space for the functional components 3; conversely, if the thickness is too thick, it will increase the overall thickness of the cover plate, thereby affecting the slim and lightweight design of mobile phones and other devices, which is inconsistent with the current development trend of consumer electronic devices.

[0025] A pre-fabricated groove 2 is pre-processed on the fiberglass board 1, and the pre-fabricated groove 2 is located on one side of the central axis of the substrate. The setting of the pre-fabricated groove 2 provides a precise installation position for the embedding of the functional component 3, ensuring the stability and reliability of the combination between the functional component 3 and the substrate, and also facilitating the subsequent encapsulation of it by the encapsulation components.

[0026] Functional component 3 is the core part of the cover plate to achieve diverse functions, and it is embedded in the prefabricated groove 2. Functional component 3 includes at least one of heat dissipation material, antenna, wireless charging module and magnetic ring.

[0027] The embedded heat-dissipating material effectively improves the heat dissipation performance of the cover. When devices such as mobile phones generate heat during operation, the heat can be quickly conducted and dissipated through the heat-dissipating material, preventing the device from overheating and affecting its performance and lifespan. The integrated antenna enables the cover to receive and transmit signals, reducing the impact of traditional external antennas on the device's appearance and improving signal transmission stability. The addition of a wireless charging module and magnetic ring provides a convenient wireless charging experience. Users do not need to insert a charging cable; they can simply place the device in the designated charging area to charge, greatly enhancing ease of use.

[0028] The encapsulation component is mounted on the substrate and can cover the prefabricated groove 2 and the functional component 3. It not only protects the functional component 3, but also enhances the overall texture and appearance of the cover plate.

[0029] The encapsulation assembly includes an OCA adhesive layer 4 bonded to the surface of the fiberglass board 1, with a thickness of 0.025 ± 0.003 mm. This precise thickness control ensures the bonding and optical properties of the OCA adhesive layer 4, guarantees a firm and smooth bond between components, and reduces the generation of bubbles and defects.

[0030] The OCA adhesive layer 4 is fitted with a decorative film 5, the color and texture of which can be customized according to customer requirements. This diverse selection of films allows for a rich variety of cover plate colors and textures, satisfying different consumers' demands for personalized appearance and making the cover plate more attractive.

[0031] A glass sheet 6 is provided on the diaphragm 5. The addition of the glass sheet 6 gives the cover glass a texture and significantly improves the appearance quality of the cover, giving it a high-end and exquisite feel in terms of both sight and touch, and making up for the lack of texture in traditional composite material cover plates.

[0032] Cover plate processing equipment is key to achieving precise and efficient cover plate production, including cutting machines, laminating machines, fixtures, debubbling machines, presses, and dispensing machines.

[0033] The cutting machine is used to precisely cut materials such as fiberglass board 1, ensuring that the material dimensions meet processing requirements. Its high-precision cutting capability ensures that the cut material has neat edges and accurate dimensions, laying a good foundation for subsequent bonding and other processes.

[0034] The laminating machine is mainly used for bonding OCA adhesive layer 4, film 5, etc. to fiberglass board 1. It can precisely control parameters such as pressure, temperature and speed during the bonding process to ensure the firmness and uniformity of the bonding and reduce the generation of bubbles and wrinkles.

[0035] Fixtures play a crucial role in securing and moving materials throughout the entire processing. Whether it's cutting, bonding, or other processes, fixtures ensure accurate material positioning, preventing material movement from affecting processing precision, and also improving the automation and safety of the processing.

[0036] A degassing machine is used to remove air bubbles generated during the bonding process. By treating the material with specific temperatures and pressures, air bubbles are released, ensuring a tight bond between the layers of the cover plate and improving its overall quality and appearance.

[0037] The press is mainly used to press the fiberglass board 1, diaphragm 5, and glass sheet 6 together to form a tightly bonded diaphragm-fiberglass board composite. The press can provide uniform and stable pressure to ensure optimal bonding between the components.

[0038] The dispensing machine is used to apply adhesive when installing decorative elements on the diaphragm-fiberglass composite. It can precisely control the amount of adhesive and the dispensing position, ensuring that the decorative elements are firmly installed and accurately positioned, thus improving the overall aesthetics of the cover plate.

[0039] Processing methods of cover plate processing equipment:

[0040] S1. Fiberglass board cutting and pretreatment

[0041] First, the fiberglass board 1 to be cut is mounted on the cutting machine using a clamp. The clamp securely holds the fiberglass board 1, preventing displacement during the cutting process. Then, the cutting machine cuts the fiberglass board 1 to the required size. During the cutting process, the high-precision blades and control system of the cutting machine ensure the accuracy of the cut dimensions. After cutting, the protective film on the outside of the fiberglass board 1 is removed. Care must be taken during the removal of the protective film to avoid scratching the surface of the fiberglass board 1. Next, the fiberglass board 1 is placed into the laminating machine using a clamp, preparing for the subsequent bonding of the OCA adhesive layer.

[0042] S2, Electrostatic dust removal and OCA adhesive layer bonding

[0043] The cut fiberglass board 1 undergoes electrostatic dust removal because static electricity is generated during the removal of the protective film, which easily attracts dust particles. Without dust removal, the dust will affect the adhesion of the OCA adhesive layer, leading to defects such as bubbles. Electrostatic dust removal can be performed using professional dust removal equipment to ensure the surface of the fiberglass board 1 is clean.

[0044] Subsequently, an OCA adhesive layer 4 with a thickness of 0.022-0.028 mm is applied to the surface of the fiberglass board 1 using a laminating machine. The laminating machine precisely controls the pressure, temperature and lamination speed to ensure that the OCA adhesive layer 4 is tightly bonded to the surface of the fiberglass board 1, thus guaranteeing the quality of the bonding.

[0045] S3, Secondary Cutting

[0046] The fiberglass board 1 covered with OCA adhesive layer 4 is moved again to the cutting machine by the clamp. This cutting is to further cut the fiberglass board 1 covered with OCA adhesive layer 4 according to the requirements of subsequent processing and assembly, so as to ensure that its size matches the subsequent components such as film 5 and glass sheet 6, and to prepare for the subsequent pressing process.

[0047] S4, Compressing to form a composite

[0048] The cut fiberglass board 1 is moved to the press using a clamp, and a membrane 5 and a glass sheet 6 are then applied to the outside of the fiberglass board 1. The color and texture of the membrane 5 can be determined according to customer requirements, while the glass sheet 6 is made of a material with good texture and transparency. Then, the press applies uniform and appropriate pressure to bond the fiberglass board 1, membrane 5, and glass sheet 6 together, forming a membrane-fiberglass board composite. During the pressing process, the pressure and pressing time need to be carefully controlled to ensure the bonding strength and appearance quality of the composite.

[0049] S5, Defoaming treatment

[0050] The membrane-fiberglass composite, after being pressed with glass, is transferred to a degassing machine using a clamp for degassing treatment. During the pressing process, a small number of air bubbles may remain between the layers. The degassing machine uses a certain temperature and pressure to gradually release these air bubbles, thereby ensuring a tight bond between the layers of the membrane-fiberglass composite and improving the overall quality and service life of the cover plate.

[0051] S6. Install decorative parts

[0052] The degassed membrane-fiberglass board composite is transferred to a dispensing machine using a clamp. The dispensing machine precisely dispenses adhesive at designated locations on the composite according to a preset program. Then, decorative elements are installed at the dispensing locations. After the adhesive cures, the decorative elements are firmly fixed to the composite. The installation of decorative elements not only enhances the aesthetics of the cover plate but also provides a degree of protection.

[0053] Through the above series of precise processing steps, the cover plate is finally manufactured. The entire processing is simple, cost-controllable, and highly reproducible, meeting the conditions for mass production and enabling the efficient production of cover plates with excellent texture, diverse functions, and personalized appearance.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and the inventive concept of the present invention, should be covered within the scope of protection of the present invention.
