Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of VR glasses, and in particular relates to a release film composite structure of a sealing tape for VR glasses. Background Art
[0002] Virtual reality glasses, also known as VR glasses, are specialized glasses used for virtual reality technology. They present the content of virtual reality applications to the user's two eyes separately through split-screen technology, creating an immersive virtual experience. Users can interact and operate in the virtual environment through VR glasses.
[0003] VR glasses are usually composed of display devices, coated lenses, lens holders and lenses. Sealing tape is required between the lenses and display devices, lens holders and lenses to achieve a sealed connection. Sealing tape is usually a frame glue structure with a small width. After cutting and forming, it has high requirements for transportation cleanliness and fitting accuracy. Abnormalities such as edge fuzz, powder, and pulling deformation of the sealing tape will affect the quality of VR glasses, especially if foreign objects enter the window of VR glasses. They will be magnified several times and affect the perception, which makes it difficult to control the production yield. In addition, if the sealing tape is abnormal after fitting and needs to be reworked, it is difficult to tear it off, which can easily affect other components. Utility Model Content

[0023] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The drawings of the present invention are only for illustration to make it easier to understand the present invention, and the specific proportions can be adjusted according to design requirements. The upper and lower relationships of the relative elements and the definitions of the front and back sides in the figures described in the text should be understood by those skilled in the art to refer to the relative positions of the components, so they can all be flipped to present the same components, which should all fall within the scope disclosed in this specification.
[0024] refer to Figures 1 to 3b The release film composite structure of the VR glasses sealing tape of the embodiment includes a sealing tape 1, a light release film 2 and a heavy release film 3. The sealing tape 1 has an annular structure and has a first tearing hand 11 extending outward from the annular structure. The annular structure is sandwiched between the light release film 2 and the heavy release film 3, and the light release film 2 and the heavy release film 3 have the same or similar outer contour as the annular structure. The light release film 2 has a second tearing hand 21 protruding outward, and the position of the second tearing hand 21 preferably coincides with the first tearing hand 12. The heavy release film 3 has a hollow area 3a in the inner circle of the annular structure of the sealing tape 1, and has a third tearing hand 31 protruding inwardly from the hollow area 3a. There is a cutout 32 between the outer contour edge of the heavy release film 3 and the edge of the hollow area 3a. The sealing tape 1 is protected between the light release film 2 and the heavy release film 3 to ensure cleanliness during the process and transfer and transportation, and is separated and composited with the target product through a convenient peeling process of the light release film 2 and the heavy release film 3 during the lamination process.
[0025] Specifically, the sealing tape 1 is used as a frame glue, and its annular structure is adapted to the shape of the VR glasses frame, including but not limited to round, oval, square, rounded square and other design frame shapes, etc. The ring width of the sealing tape 1 is 0.5-1.5 mm, and the thickness is 0.01-0.1 mm. Figure 2, the outer contour edge 3b of the heavy release film 3 coincides with the outer contour edge 1b of the annular structure of the sealing tape 1, providing load bearing and protection on one side. The outer contour of the light release film 2 is consistent with the outer contour shape of the annular structure of the sealing tape 1, and the outer contour edge 2b of the light release film 2 extends a certain distance outward relative to the outer contour edge 1b of the annular structure, providing load bearing and protection on the other side, ensuring that the annular structure is within the coverage range of both. The light release film 2 is arranged on the entire surface, and the heavy release film 3 forms a ring-like shape through the arrangement of the middle hollow area 3a, and its ring width is greater than the ring width of the sealing tape 1. Preferably, the heavy release film 3 has two third tearing fingers 31 arranged radially opposite to each other, and the center lines of the second tearing finger 21 and the two third tearing fingers 31 are located on the same straight line, and the third tearing finger 31 is, for example, a semicircular, square, or other shape protruding toward the inner side of the middle hollow area 3a. Reference Figure 4 The cut 32 is located on one side of a third tearing hand 31, and cuts off the heavy release film 3 in a radial square shape along the annular structure.
[0026] During the laminating process of assembling VR glasses, first peel off the light release film 2 through the second tearing hand 21, and stick one side of the sealing tape 1 into the frame of the VR glasses, and then peel off the heavy release film 3. When peeling off the heavy release film 3, it can be operated from the inner hollow area 3a through the third tearing hand 31, avoiding the limitation of the external structure and facilitating the automated production. By grabbing the third tearing hand 31 and pulling it from the incision 32, the heavy release film 3 is gradually separated from the sealing tape 1 from one side of the third tearing hand 31. Compared with the state of simultaneous separation on both sides without the incision, the problem of deformation of the sealing tape 1 when tearing the film is avoided. The width of the incision 32 is less than 0.3 mm, and it is formed by cutting. If the incision 32 is too large, it is easy for contaminants to enter and contaminate the sealing tape 1.
[0027] Combination Figure 1 and Figure 2, the second tearing hand 21 overlaps with the position of the first tearing hand 11 and covers one side of the first tearing hand 11. The first tearing hand 11 includes two independently arranged hand grips 111, and the second tearing hand 21 is arranged as a whole and covers the two hand grips 111. The other side opposite to the hand grip 111 is attached with a support layer 4, and the tensile strength of the material of the support layer 4 is greater than the tensile strength of the material of the sealing tape 1. For example, the material of the sealing tape is PSA glue (pressure-sensitive adhesive), the material of the support layer 4 is PET, and the thickness of the support layer 4 is 0.03-0.1mm. The outer contour edge of the support layer and the heavy release film 3 does not overlap, and there is a gap of less than 0.1mm. The overlap of the support layer and the heavy release film 3 is prone to cause problems such as bubbles, and a gap greater than 0.1mm will cause problems such as residual contaminants. When an abnormality occurs after bonding, the sealing tape 1 can be deformed and separated from the bonding structure by pulling the first tearing hand 11 for rework, thereby solving the problem that rework cannot be performed due to quality problems after bonding. The support layer 4 provides protection and support to the gripping portion 111 on one hand, and facilitates gripping and applying force on the other hand.
[0028] Combination Figure 2 , Figure 3a and Figure 3b The light release film 2 has a plurality of openings 22, which are located at the edge of the hollow area 3a of the heavy release film 3 and partially overlap with the hollow area 3a, and are preferably located at the root of the third tearing hand 31 protruding inward, that is, where the edge contour line suddenly changes, so as to facilitate the separation of the light release film 2 and the heavy release film 3 and uniform force. Furthermore, the light release film 2 and the heavy release film 3 can also be provided with openings 23 and 33 in the middle of the position of the third tearing hand 31, respectively. The openings 23 and 33 overlap and the opening 23 is preferably larger than the opening 33 to reduce the overlapping area of the two and facilitate separation. Through the above arrangement, the sealing tape 1 can be ensured to be uniformly stressed when the light release film 2 and the heavy release film 3 are torn off to avoid deformation.
[0029] The above embodiments are only used to further illustrate the release film composite structure of a VR glasses sealing tape of the utility model, but the utility model is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model fall within the protection scope of the technical solution of the utility model.
