Description

Technical Field

[0001] This utility model relates to an AR / VR composite film. Background Technology

[0002] Currently, during the alignment and bonding process of composite films, for AR / VR composite films that are thin (overall thickness < 0.2 mm) and have high adhesion (initial peel force greater than 300 gf), the equipment's robotic arm cannot properly tear / peel them, resulting in corner tearing failure, equipment alarms, and abnormal bonding and alignment photography.

[0003] To address the aforementioned issues with normal tearing / peeling, the negative pressure vacuum adsorption force at the starting point of the film tearing process was increased, and the viscosity of the film tearing tape was also increased. However, this approach has several drawbacks, such as a low success rate in film tearing, leading to reduced equipment uptime and increased production time. Furthermore, failed film tearing can easily cause creases in the product, reducing production yield and increasing production costs. Additionally, the release film and the functional layer may be torn off together, resulting in product scrap. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the defects in the existing technology and propose a thin and easy-to-peel AR / VR composite film that can guarantee 100% success rate of film peeling, thereby ensuring production efficiency and yield and improving equipment utilization.

[0005] To solve the above-mentioned technical problems, the present invention proposes the following technical solution: a thin and easily peelable AR / VR composite film with an overall thickness of less than 0.2 mm, comprising a release film, a functional layer, a petrolatum coating, and a PET circular transparent gasket; The release film covers the functional layer, and the initial peel force between the release film and the functional layer is greater than 300gf; The petrolatum coating is located between the release film and the functional layer, at the corner of both layers. A circular transparent PET pad is placed between the petroleum jelly coating and the release film, also located at the aforementioned corner position.

[0006] A further limitation of the above technical solution is that the release film and the functional layer are both rectangular in shape, and the corner position is one corner of the rectangle.

[0007] This utility model has the following beneficial effects: 1. The present invention provides a thin and easily peelable AR / VR composite film with a petroleum jelly coating and a PET circular transparent gasket sandwiched between the release film and the functional layer. In this area, the release film and the functional layer are in a non-adhesive and separated state. The robotic arm only needs to apply a small amount of force to the release film to easily peel it off, which can guarantee a 100% success rate in peeling the film, thereby ensuring production efficiency and yield and improving equipment uptime. 2. The thin and easily peelable AR / VR composite film of this utility model can improve product yield, facilitate PMC's control over the procurement of raw materials, and reduce raw material waste; 3. The thin and easily peelable AR / VR composite film of this invention can improve stable output, meet customer order delivery in a timely manner, and improve customer order delivery satisfaction. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of the thin and easily peelable AR / VR composite film of this utility model. Detailed Implementation

[0009] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0010] like Figure 1 As shown, this utility model proposes a thin and easily peelable AR / VR composite film with an overall thickness of less than 0.2 mm, including a release film 1, a functional layer 2, a petrolatum coating 3, and a PET circular transparent gasket 4.

[0011] Release film 1 covers functional layer 2. The adhesion between release film 1 and functional layer 2 is relatively strong, and the initial peel force is greater than 300gf.

[0012] Both the release film 1 and the functional layer 2 are rectangular in shape.

[0013] The petroleum jelly coating 3 is located between the release film 1 and the functional layer 2, at the corner of the release film 1 and the functional layer 2, for example, at one corner of the rectangle of the functional layer 2.

[0014] A PET circular transparent pad 4 is disposed between the petroleum jelly coating 3 and the release film 1, and is also located at the aforementioned corner position.

[0015] The method for manufacturing the thin, easily peelable AR / VR composite film includes the following steps: Step 1: Corner lifting of the membrane material: After placing the AR / VR composite membrane material that needs to be lifted flat on the table, the operator holds a blade and finds the junction of one corner of the release film 1 and the functional layer 2 of the AR / VR composite membrane material. After inserting the blade at the junction, the blade is lifted upward to lift the release film 1, so that the release film 1 and the functional layer 2 are separated. The size of the separation area is approximately 15*15mm.

[0016] Step 2: Apply Vaseline: Dip the round end of the rolled-up lint-free cotton swab in an appropriate amount of Vaseline and apply it evenly to the separation area between the functional layer 2 and the release film 1. Using Vaseline ensures that after a long period of storage, the release film 1 and the functional layer 2 will not stick together again in the separation area where Vaseline is applied, which can effectively improve the success rate of the robot arm in tearing the film during production.

[0017] Step 3: Place a PET round transparent pad 4: Take a PET round transparent pad 4 and place it in the middle of the separation area where Vaseline has been applied. Using a PET round transparent pad 4 can ensure that the visual appearance is not affected when the camera is aligning the edges.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a thin and easily peelable AR / VR composite film, in which a petrolatum coating 3 and a PET circular transparent gasket 4 are sandwiched between the release film 1 and the functional layer 2. In this area, the release film 1 and the functional layer 2 are in a non-adhesive separated state. The robotic arm only needs to apply a small amount of force to the release film 1 to easily peel it off, which can guarantee a 100% success rate in peeling the film, thereby ensuring production efficiency and yield and improving equipment uptime. 2. The thin and easily peelable AR / VR composite film of this utility model can improve product yield, facilitate PMC's control over the procurement of raw materials, and reduce raw material waste; 3. The thin and easily peelable AR / VR composite film of this invention can improve stable output, meet customer order delivery in a timely manner, and improve customer order delivery satisfaction.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
