Description

Technical Field

[0001] This utility model relates to the technical field of anti-glare optical film lamination devices, and particularly to an anti-glare optical film lamination structure for VR. Background Technology

[0002] With the rapid development of virtual reality (VR) technology, users' demands for VR device experiences are increasing. VR devices need to create highly realistic and immersive virtual environments for users, which places stringent standards on their optical display systems. As a key component of the optical display system of VR devices, the optical film plays a crucial role.

[0003] In VR devices, optical films play a crucial role in reducing reflection, increasing light transmittance, and optimizing light distribution. By reducing reflection, stray light interference can be effectively avoided, preventing phenomena such as glare and ghosting, thereby improving image clarity and contrast and presenting users with clearer and more realistic virtual images. Increasing light transmittance allows more light to enter the human eye, improving display brightness and ensuring clear visibility of images even in complex lighting environments. Optimizing light distribution can simulate real-world lighting conditions, enhancing the user's immersion. For example, the application of ultra-black coatings in VR / AR optical systems can almost completely absorb light in the visible light (VIS) and near-infrared (NIR) spectral ranges, effectively reducing stray light effects and improving image quality.

[0004] However, traditional optical film lamination technology has gradually revealed many drawbacks when facing the ever-upgrading demands of VR devices. During the lamination process, it is difficult to completely eliminate air between the films, which makes the laminated products prone to defects such as bubbles and voids, seriously affecting the optical performance and service life of the optical film. In addition, conventional lamination technology has poor adhesion between films, and the films are not firmly bonded, which may lead to delamination during use, reducing the stability and reliability of VR devices. Moreover, traditional lamination processes often require step-by-step operations, resulting in low equipment integration, low production efficiency, and difficulty in meeting the needs of large-scale production. At the same time, the high scrap rate also leads to high production costs.

[0005] To meet the urgent demand of the VR market for high-quality optical films and overcome the limitations of traditional lamination technology, it is imperative to develop an efficient, precise device that can guarantee lamination quality. This is the technological background for the birth of VR anti-glare optical film lamination equipment. It aims to solve existing problems through innovative design and the integration of multiple technologies, promote VR optical film manufacturing technology to a new level, and provide strong support for the sustainable development of the VR industry. Utility Model Content

[0006] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an anti-glare optical film lamination structure for VR, which can solve the above-mentioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-glare optical film lamination structure for VR, comprising a base and a hydraulic cylinder, wherein the hydraulic cylinder is disposed above the base, a housing is fixedly connected to the base, and a support foot is fixedly connected to the bottom of the base;

[0008] A sealing ring is fixedly connected to the opening of the outer shell, a hinge is fixedly connected to one side of the opening of the outer shell, a door panel is rotatably connected to the hinge, and an observation window and a handle are fixedly connected to the door panel.

[0009] Several heating elements are fixedly connected to the left and right walls of the outer shell. The hydraulic cylinder is fixedly connected to the outer shell. A pressure plate is fixedly connected to the working end of the hydraulic cylinder. A flexible pressure head is fixedly connected below the pressure plate.

[0010] A vacuum pipe is fixedly connected to the rear end of the housing, and a vacuum generator is fixedly connected to the other end of the vacuum pipe. An ultrasonic transducer is fixedly connected to the bottom of the base, and a conduit is fixedly connected to the ultrasonic transducer. An ultrasonic generator is fixedly connected to the other end of the conduit. A control panel is fixedly connected to one side of the housing, and the control panel is electrically connected to the ultrasonic generator and the vacuum generator via wiring.

[0011] Preferably, the heating elements are evenly distributed within the left and right walls of the outer casing.

[0012] Preferably, the sealing ring is an annular rubber sealing ring.

[0013] Preferably, a control valve is provided on the air extraction pipe.

[0014] Preferably, the control panel is provided with control buttons for controlling the working status of the hydraulic cylinder and the heating element.

[0015] Preferably, a shock-absorbing pad is provided between the ultrasonic transducer and the base.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This VR uses an anti-glare optical film lamination structure. The lamination process begins with the control panel activating a vacuum generator. The vacuum generator extracts air from the inside of the casing through a suction pipe, creating a vacuum environment. This step effectively eliminates air between the films, preventing defects such as air bubbles after lamination and ensuring the quality of the optical film lamination. The ultrasonic transducer below the base, driven by the ultrasonic generator and controlled by the control panel, begins operation. The ultrasonic transducer converts electrical energy into ultrasonic energy, which is transmitted to the optical film through the base. The high-frequency vibration of the ultrasonic waves further promotes the fusion between film molecules, enhances the adhesion between films, and improves the strength of the lamination.

[0018] 2. This VR uses an anti-glare optical film lamination structure. The control panel activates a hydraulic cylinder, which pushes a pressure plate and a flexible pressure head downwards, applying pressure to the heated optical film. The flexible pressure head ensures even pressure distribution on the film, preventing deformation or damage due to uneven pressure. Under pressure, the optical film layers adhere tightly. Throughout the lamination process, the operator can observe the lamination status in real time through an observation window on the door panel. Once lamination is complete, the control panel is used to shut down all components, open the door panel, and remove the laminated VR anti-glare optical film, completing one lamination operation.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] Please see Figure 1-4 This utility model provides a technical solution: an anti-glare optical film lamination structure for VR, including a base 1 and a hydraulic cylinder 2. The hydraulic cylinder 2 is disposed above the base 1. A shell 3 is fixedly connected to the base 1, and a support leg 4 is fixedly connected to the bottom of the base 1.

[0030] A sealing ring 9 is fixedly connected to the opening of the outer shell 3. A hinge 5 is fixedly connected to one side of the opening of the outer shell 3. A door panel 6 is rotatably connected to the hinge 5. An observation window 7 is fixedly connected to the door panel 6. A handle 8 is fixedly connected to the door panel 6.

[0031] In the preparation stage, the VR anti-glare optical film to be laminated is placed on the base 1. The door panel 6 is opened by the handle 8 and the hinge 5. After the film is placed in the appropriate position, the door panel 6 is closed. The sealing ring 9 at the opening of the door panel 6 can ensure the airtightness of the inside of the outer shell 3.

[0032] Several heating elements 12 are fixedly connected to the left and right walls of the outer shell 3. A hydraulic cylinder 2 is fixedly connected to the outer shell 3. A pressure plate 10 is fixedly connected to the working end of the hydraulic cylinder 2. A flexible pressure head 11 is fixedly connected below the pressure plate 10.

[0033] The heating elements 12 inside the left and right walls of the outer casing 3 start working under the control of the control panel 18 to heat the internal optical film. Heating can reduce the viscosity of the film material and improve its fluidity, so that the film can better adhere when subjected to pressure, enhancing the lamination effect. The flexible pressure head 11 can ensure that the pressure is applied evenly to the film, avoiding deformation or damage to the film due to uneven pressure. Under the action of pressure, the layers of optical film are tightly adhered.

[0034] A vacuum pipe 16 is fixedly connected to the rear end of the outer casing 3, and a vacuum generator 17 is fixedly connected to the other end of the vacuum pipe 16. An ultrasonic transducer 13 is fixedly connected to the bottom of the base 1. A conduit 14 is fixedly connected to the ultrasonic transducer 13, and an ultrasonic generator 15 is fixedly connected to the other end of the conduit 14. A control panel 18 is fixedly connected to one side of the outer casing 3. The control panel 18 is electrically connected to the ultrasonic generator 15 and the vacuum generator 17 through wiring.

[0035] Entering the lamination process, firstly, the control panel 18 controls the vacuum generator 17 to start. The vacuum generator 17 extracts the air inside the outer shell 3 through the air extraction pipe 16 to form a vacuum environment. This step can effectively remove the air between the films, avoid defects such as bubbles after lamination, and ensure the lamination quality of the optical film.

[0036] Working principle: In the preparation stage, the VR anti-glare optical film to be laminated is placed on the base 1. The door panel 6 is opened by the handle 8 and the hinge 5. After the film is placed in the appropriate position, the door panel 6 is closed. The sealing ring 9 at the opening of the door panel 6 can ensure the sealing of the inside of the outer shell 3, providing conditions for subsequent vacuum operation.

[0037] Entering the lamination process, firstly, the control panel 18 controls the vacuum generator 17 to start. The vacuum generator 17 extracts the air inside the outer shell 3 through the air extraction pipe 16 to form a vacuum environment. This step can effectively remove the air between the films, avoid defects such as bubbles after lamination, and ensure the lamination quality of the optical film.

[0038] After the vacuum environment is established, the heating elements 12 inside the left and right walls of the outer shell 3 start to work under the control of the control panel 18, heating the internal optical film. Heating can reduce the viscosity of the film material, improve its fluidity, and enable the film to better adhere when subjected to pressure, thus enhancing the lamination effect.

[0039] Next, the control panel 18 activates the hydraulic cylinder 2. The actuating end of the hydraulic cylinder 2 pushes the pressure plate 10 and the flexible pressure head 11 below it downwards, applying pressure to the heated optical film. The flexible pressure head 11 ensures that the pressure is applied evenly to the film, preventing deformation or damage to the film due to uneven pressure. Under the pressure, the layers of the optical film adhere tightly.

[0040] At the same time, the ultrasonic transducer 13 under the base 1 starts to work under the control of the ultrasonic generator 15 and the control panel 18. The ultrasonic transducer 13 converts electrical energy into ultrasonic energy, which is transmitted to the optical film through the base 1. The high-frequency vibration of the ultrasonic waves can further promote the fusion between the film molecules, enhance the adhesion between the films, and improve the strength of the lamination.

[0041] Throughout the lamination process, the operator can observe the lamination of the internal optical film in real time through the observation window 7 on the door panel 6. After lamination is completed, the operator can turn off all components through the control panel 18, open the door panel 6, take out the laminated VR anti-glare optical film, and complete one lamination operation.

[0042] The equipment, through the cooperation of vacuum generator 17 and air extraction pipe 16, creates a vacuum environment inside the outer shell 3, which can completely eliminate air between optical films, thereby avoiding defects such as bubbles and voids after lamination, ensuring the light transmittance and surface flatness of the optical film, and improving the visual effect of VR equipment. At the same time, the heating element 12, flexible pressure head 11 and ultrasonic transducer 13 work together to reduce the viscosity of the film by heating, ensure uniform pressure by the flexible pressure head 11, and promote molecular fusion by ultrasonic waves. The combination of the three makes the films fit tightly and bond firmly, enhancing the overall stability and durability of the optical film, and effectively reducing rework and scrap rates caused by poor lamination quality.

[0043] This equipment integrates multiple functions such as vacuum processing, heating, pressurization, and ultrasonic processing. It can complete a series of key processes for optical film lamination in the same enclosed space, eliminating the need to transfer the film to different equipment for step-by-step processing, thus simplifying the production process. At the same time, the control panel 18 enables centralized automated control of each component. Operators only need to set parameters through the control panel 18 to quickly start and stop the equipment, reducing manual intervention and operational errors, shortening the lamination time of a single product, and achieving efficient mass production.
