Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging materials, and more specifically to a splicing diffusion film. Background Art
[0002] Currently, many vehicle-mounted cover panels and touch screens have display buttons, and a backlight module is provided under the display buttons. In order to make the display buttons transmit light evenly, a diffusion film is usually added between the display buttons and the backlight module. Generally, when the display buttons are close and the structure allows, the diffusion film is made into a whole sheet to cover all display buttons. However, if the display buttons are far away or the display buttons are not on the same plane or the structure does not allow, the diffusion film needs to be designed in a grained manner, that is, each display button needs to be covered with a separate diffusion film. In this way, each display button needs to be attached during production. Moreover, this display button diffusion film is relatively small and difficult to take by hand or machine, resulting in a long film pasting process, low film pasting efficiency, low film pasting yield, and expensive film pasting labor. Utility Model Content
[0003] The technical problem to be solved by the utility model is how to design a diffusion film that can bring together all the diffusion films of granular design so that they only need to be attached once, thereby improving the film attachment efficiency.

[0028] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0029] The utility model provides a splicing diffusion film, which comprises a light release film, a double-sided adhesive layer, a diffusion film layer, a positioning film and a heavy release film which are sequentially stacked from bottom to top, wherein the diffusion film layer is provided with a plurality of dispersed diffusion films, the double-sided adhesive layer is provided with a plurality of double-sided adhesives corresponding to the number and position of the diffusion films, the positioning film has weak viscosity, a plurality of positioning holes are provided on both sides of the heavy release film, and the positioning film located at and near the positioning holes has no viscosity.
[0030] Since the positioning film is provided with multiple dispersed diffusion films, each diffusion film is provided with a corresponding double-sided adhesive. When pasting the collage diffusion film, first tear off the light release film, and then use the positioning holes on the heavy release film for alignment. After alignment, the double-sided adhesive is pasted to complete the attachment of multiple diffusion films. Only one film pasting operation is required, thereby shortening the film pasting process, improving the film pasting efficiency and film pasting yield, reducing the film pasting cost, and improving the competitiveness of the product.
[0031] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.
[0032] Example 1
[0033] See also Figure 1 and Figure 2 , a kind of splicing diffusion film provided by the utility model comprises a light release film 1, a double-sided adhesive layer 2, a diffusion film layer 3, a positioning film 4 and a heavy release film 5 which are sequentially stacked from bottom to top, the diffusion film layer 3 is provided with a plurality of diffusers arranged in a dispersed manner, the double-sided adhesive layer 2 is provided with a plurality of double-sided adhesives, the number and position of the plurality of double-sided adhesives correspond to the number and position of the diffusers, the positioning film 4 has weak viscosity, a plurality of positioning holes 51 are provided on both sides of the heavy release film 5, and the positioning film 4 located at and near the positioning holes 51 is not sticky, so as to facilitate the operation without sticking to the hands. Since a plurality of diffusers arranged in a dispersed manner are arranged on the positioning film 4, and each diffuser film is provided with a double-sided adhesive, when pasting the splicing diffusion film, the light release film 1 is first torn off, and then the positioning holes 51 on the heavy release film 5 are used for alignment, and after alignment, the double-sided adhesive is pasted to complete the pasting of the plurality of diffusers, and only one film pasting operation is required, thereby shortening the film pasting process, improving the film pasting efficiency and the film pasting yield, reducing the film pasting cost, and improving the competitiveness of the product.
[0034] Furthermore, two positioning holes 51 are provided on the left and right sides of the heavy release film 5 .
[0035] Furthermore, the diffusion film layer 3 is provided with 8 dispersed diffusion films.
[0036] See also Figure 3 Furthermore, a film tearing handle 6 is provided on the light release film 1 to facilitate tearing off the release film.
[0037] Furthermore, the film tearing handle 6 is provided with a color, and more preferably, the color is red, which is more eye-catching.
[0038] Example 2
[0039] See also Figure 3 and Figure 4 As a further optimization scheme of Example 1, in this embodiment, a "concave" shaped through hole 7 is opened on the light release film 1, and the residual material of the "concave" shaped through hole 7 forms a film tearing handle 6, so there is no need to add a film tearing handle 6 on the periphery of the light release film 1. Therefore, the film tearing handle 6 will not be unable to be placed due to the limitation of the peripheral space, avoiding the situation where tweezers need to be used to lift the film when the peripheral space is limited, thereby saving labor costs; and the material of the peripheral film tearing handle 6 can be omitted, which can greatly reduce the material cost.
[0040] Furthermore, the waste material 8 of the “concave”-shaped through hole 7 remains on the light release film 1. Before the light release film 1 is torn off, the waste material 8 is still connected to the light release film 1, which can effectively prevent dust or other particles from entering the product surface. Since the waste material 8 is still connected to the light release film 1, it is difficult to tear off the film tearing handle 6 at this time, so an adhesive area 9 can be set on the upper surface of the waste material 8, preferably adhesive, but not limited to this. When tearing off the upper light release film 1, the waste material 8 can be torn off with the adhesive first, and then the light release film 1 can be torn off with the film tearing handle 6.
[0041] Furthermore, the “concave”-shaped through hole 7 is arranged at the edge of the light release film 1 , so that the light release film 1 is easier to tear off, and the tearing handle 6 is not damaged due to high tearing difficulty.
[0042] Furthermore, each corner of the “concave”-shaped through hole 7 is provided with a rounded corner, so that the stress during film tearing is not concentrated at the corner, thereby avoiding the film tearing handle 6 from being torn due to stress concentration, and further improving the working efficiency.
[0043] Furthermore, the radius of the rounded corner is 1 mm.
[0044] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0045] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive. Although the present application is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to perform equivalent replacement of some of the technical features therein. Any equivalent structure made using the contents of the specification and drawings of this application, directly or indirectly used in other related technical fields, is similarly within the scope of patent protection of this application.
