Technical Field

[0001] The utility model relates to the technical field of diffusion pasting, and more specifically to a diffusion film and a clamp structure for pasting the same. Background Art

[0002] In today's increasingly developed display technology field, especially in electronic devices such as touch screens, tablets, and mobile phones, the backlight light source processing of icons is particularly critical. In order to provide a good user experience and visual effects, the backlight light source of icons must be properly controlled to avoid the appearance of the light eye effect, that is, the light source is too concentrated and dazzling. The traditional solution is to stick diffusion films on the back of icons one by one. The diffusion film is a special optical material. Its surface structure can effectively scatter the light, so that the light is more evenly distributed on the icon, thereby achieving the purpose of avoiding the light eye effect. However, this one-by-one attachment method has many shortcomings;

[0003] First, the method of attaching diffusion films one by one is inefficient. In the manufacturing process of electronic devices, time is money. The traditional attachment method requires manual attachment of diffusion films on the ICON one by one, which not only increases production time, but also limits the overall efficiency of the production line; secondly, the cost of manual operation is high. Attaching diffusion films one by one requires a lot of manual participation, which not only requires a lot of human resources, but also requires high labor costs. In addition, there are certain errors and uncertainties in manual operation, which may affect the accuracy and consistency of attachment; finally, the method of attaching one by one also has the risk of missing attachment. In the large-scale and fast production process, it is difficult for manual operation to ensure that each ICON is attached with a diffusion film, which will lead to quality problems in some products and affect user experience and corporate reputation. Therefore, we make improvements on this and propose a diffusion film and a fixture structure for its attachment. Utility Model Content

The appearance of this phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] As described in the background technology, in the prior art, a diffusion film is pasted on the back of the ICON one by one. The diffusion film is a special optical material, and its surface structure can effectively disperse the light, so that the light is more evenly distributed on the ICON, thereby achieving the purpose of avoiding the lamp eye effect. However, this method of attaching one by one has many shortcomings; first, the method of attaching the diffusion film one by one is inefficient. In the manufacturing process of electronic equipment, time is money. The traditional attachment method requires manual attachment of the diffusion film on the ICON one by one, which not only increases the production time, but also limits the overall efficiency of the production line; secondly, the manual operation cost is high, and attaching the diffusion film one by one requires a lot of manual participation, which not only requires a lot of human resources, but also requires high labor costs. In addition, there are certain errors and uncertainties in manual operation, which may affect the accuracy and consistency of attachment; finally, the method of attaching one by one also has the risk of missing attachment. In the large-scale and rapid production process, it is difficult to ensure that each ICON is affixed with a diffusion film by manual operation, which will cause quality problems in some products and affect user experience and corporate reputation.

[0027] In order to solve this technical problem, the utility model provides a diffusion film and a fixture structure for pasting the diffusion film.

[0028] Specifically, please refer to Figure 1-Figure 2 The diffusion film and the fixture structure for pasting the diffusion film specifically include:

[0029] The heavy release film body 2 and several diffusion film bodies 1 of preset sizes are arranged on the diffusion film body 1 according to the position of the ICON on the cover plate.

[0030] The utility model provides a diffusion film and a fixture structure for pasting the same. The utility model sets a plurality of diffusion film bodies 1 on a heavy release film body 2 so that a required number of diffusion film bodies 1 can be pasted to a cover plate at one time during pasting, thereby significantly improving production efficiency, reducing labor costs, and effectively avoiding the problem of missing pasting. By pasting a plurality of diffusion film bodies 1 at one time, the number of operations is reduced, thereby significantly improving production efficiency.

[0031] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] Example 1, please refer to Figure 1-Figure 2 The diffusion membrane provided by the utility model includes: a heavy release membrane body 2 and a plurality of diffusion membrane bodies 1 of preset sizes, wherein the plurality of diffusion membrane bodies 1 are arranged on the diffusion membrane body 1 according to the position of the ICON on the cover plate, and the heavy release membrane body 2 is used to carry the plurality of diffusion membrane bodies 1 to achieve synchronous bonding of the plurality of diffusion membrane bodies 1. The present application arranges the plurality of diffusion membrane bodies 1 on the heavy release membrane body 2 so that the required number of diffusion membrane bodies 1 can be pasted to the cover plate at one time during bonding, which significantly improves the production efficiency, reduces the labor cost, and effectively avoids the problem of missing bonding; by attaching a plurality of diffusion membrane bodies 1 at one time, the number of operations is reduced, and the production efficiency is significantly improved.

[0035] Furthermore, a sticking portion is provided on one side of the diffusion membrane body 1 away from the double-sided adhesive body 3, and the sticking portion is used to stick the diffusion membrane body 1 to the cover plate, that is, the sticking portion can stick the diffusion membrane body 1 to the cover plate together, so as to install the diffusion membrane body 1.

[0036] Further, such as Figure 1 As shown, the adhesive portion is a double-sided adhesive body 3, which is adhered to the side of the diffusion membrane body 1 away from the heavy release membrane body 2. By adhering the double-sided adhesive body 3 to the diffusion membrane body 1, the diffusion membrane body 1 and the cover plate are adhered together through the double-sided adhesive body 3 when in use.

[0037] Example 2, please refer to Figure 1-Figure 2 The diffusion membrane provided by the utility model includes: a heavy release membrane body 2 and a plurality of diffusion membrane bodies 1 of preset sizes, wherein the plurality of diffusion membrane bodies 1 are arranged on the diffusion membrane body 1 according to the position of the ICON on the cover plate, and the heavy release membrane body 2 is used to carry the plurality of diffusion membrane bodies 1 to achieve synchronous bonding of the plurality of diffusion membrane bodies 1. The present application arranges the plurality of diffusion membrane bodies 1 on the heavy release membrane body 2 so that the required number of diffusion membrane bodies 1 can be pasted to the cover plate at one time during bonding, which significantly improves the production efficiency, reduces the labor cost, and effectively avoids the problem of missing bonding; by attaching a plurality of diffusion membrane bodies 1 at one time, the number of operations is reduced, and the production efficiency is significantly improved.

[0038] Furthermore, a sticking portion is provided on one side of the diffusion membrane body 1 away from the double-sided adhesive body 3, and the sticking portion is used to stick the diffusion membrane body 1 to the cover plate, that is, the sticking portion can stick the diffusion membrane body 1 to the cover plate together, so as to install the diffusion membrane body 1.

[0039] Further, such as Figure 1 As shown, the adhesive portion is a double-sided adhesive body 3, which is adhered to the side of the diffusion membrane body 1 away from the heavy release membrane body 2. By adhering the double-sided adhesive body 3 to the diffusion membrane body 1, the diffusion membrane body 1 and the cover plate are adhered together through the double-sided adhesive body 3 when in use.

[0040] Further, such as Figure 1 As shown, a protective member is provided behind a plurality of double-sided adhesive bodies 3 away from a side of the diffusion membrane body 1, and the protective member is used for protecting the double-sided adhesive body 3 before pasting. The protective member can protect the double-sided adhesive body 3 and reduce the situation where the double-sided adhesive body 3 is affected by the external environment before pasting, resulting in a decrease in its viscosity.

[0041] Further, such as Figure 1 As shown, the protective member is a light release film body 4, which is arranged between a plurality of double-sided adhesive bodies 3 away from the side of the diffusion membrane body 1, and the light release film body 4 can protect the double-sided adhesive body 3, and reduce the situation where the double-sided adhesive body 3 is affected by the external environment before pasting, resulting in a decrease in its viscosity;

[0042] Heavy release film refers to a release film with relatively large release force. Release film is a film with distinguishable surface energy. It has slight stickiness after contacting with specific materials under limited conditions. In the production process of release film, plasma treatment, fluorine treatment or silicone release agent are usually used to increase the release force of plastic film. According to the required release force, release film can be divided into light release film, medium release film and heavy release film. Heavy release film is suitable for scenes requiring stronger separation effect due to its higher release force.

[0043] A light release film refers to a release film with relatively small release force. The light release film is coated with an appropriate amount of release agent on the surface of the treated plastic film, so that the release film has an extremely light and stable release force after contact with a specific material. Due to the low release force of the light release film, it is suitable for scenes that require a smaller separation force.

[0044] Further, such as Figure 2 As shown, a positioning piece is provided on the heavy release film body 2, and the positioning piece is used to position the heavy release film body 2 to achieve positioning when the double-sided adhesive body 3 is pasted, so that the position of the double-sided adhesive body 3 and the cover plate are more accurate when they are attached.

[0045] Further, such as Figure 2 As shown, the positioning member includes a plurality of positioning holes 6, and the plurality of positioning holes 6 are all opened on the heavy release film body 2. The positioning holes 6 can be used to position the top of the heavy release film body 2 when the double-sided adhesive body 3 is pasted, so that the position of the double-sided adhesive body 3 when it is fitted with the cover plate is more accurate.

[0046] Example 2, please refer to Figure 1-Figure 2 The fixture structure for pasting diffusion membrane provided by the utility model is used for pasting diffusion membrane, and includes a fixture body 5, a second positioning groove 502 is formed on the top of the fixture body 5, and a first positioning groove 501 is formed on the bottom of the inner cavity of the second positioning groove 502.

[0047] Further, such as Figure 1 As shown, a plurality of positioning posts 503 are fixedly installed at the bottom of the inner cavity of the first positioning groove 501. The number and positions of the positioning posts 503 correspond to the number and positions of the positioning holes 6. When in use, the positioning of the heavy release film body 2 can be achieved by plugging the positioning posts 503 into the positioning holes 6.

[0048] Further, such as Figure 1 As shown, the first positioning groove 501 is used for placing the heavy release film body 2, and the second positioning groove 502 is used for positioning the cover plate. The positioning of the heavy release film body 2 is coordinated by the positioning column 503 and the positioning hole 6, thereby realizing the positioning of the diffusion membrane body 1 and the double-sided adhesive body 3. The positioning of the cover plate by the second positioning groove 502 can make the cover plate and the double-sided adhesive body 3 fit more accurately, thereby ensuring the alignment of the ICON on the cover plate and the double-sided adhesive body 3.

[0049] When in use, first place the diffusion film in the first positioning groove 501, and make the heavy release film body 2 contact with the bottom of the inner cavity of the first positioning groove 501, and the positioning column 503 is inserted into the positioning hole 6, then tear off the light release film body 4, and place the cover plate in the second positioning groove 502. At this time, the cover plate is positioned through the second positioning groove 502 so that the ICON on the cover plate is aligned with the double-sided adhesive body 3, and then press the cover plate to make the cover plate and the double-sided adhesive body 3 stick together. After the sticking is completed, the cover plate can be taken out.
