Description

Technical Field

[0001] The utility model relates to a protective film, and more precisely, to a protective film structure for adhesive materials. Background Art

[0002] In the production process of existing display modules, various adhesive materials are used, such as upper and lower polarizers, OCA glue, graphite sheets, double-sided adhesives, etc. These adhesive materials are wrapped by two layers of protective films, and the outer shape design of the protective film is the same as that of the material. When attaching, a mucosal paper needs to be pasted onto the protective film surface at any corner of the material surface, and then the protective film is torn up and pasted. When another material needs to be pasted, another protective film needs to be torn off. With the upgrade of products, the four corners of the display module are made into R-corner arc shapes. It is more difficult to tear the protective film starting from the arc position, which affects production efficiency. Moreover, adding mucosal paper for tearing the protective film will increase the processing cost.

[0003] Chinese invention patent document CN103318533B discloses a protective film, including a protective film body for attaching to a plane to be protected, and a vacuum state is formed between the protective film body and the plane to be protected. The protective film further includes a lifting part provided on the periphery of the protective film body and an opening formed on the edge of the protective film body, and the opening is adjacent to the lifting part. One end of the lifting part is provided with an adhesive part, and the lifting part is pasted on the periphery of the protective film body through the adhesive part. The lifting part is pasted on one end of the side edge of the protective film body through the adhesive part, and the part of the lifting part away from the adhesive part faces the central part of the protective film body. The lifting part is made of a flexible material, and the adhesive force between the adhesive part and the protective film body is greater than the adsorption force between the protective film body and the plane to be protected. The number of the openings is two, and the two openings are both formed on the edge of the protective film body and are respectively located on both sides of the lifting part. The first opening of the two openings is formed on the edge of the protective film body adjacent to and close to the side edge provided with the lifting part, and the position of the first opening is opposite to the non-bonding junction position of the bonding between the lifting part and the protective film body; the second opening of the two openings is formed on the side edge of the protective film body provided with the lifting part and is adjacent to the lifting part. The shape of the opening is triangular. The shape of the opening is semi-circular. Obviously, by setting the lifting part and the opening, when the user lifts the lifting part, air can enter between the protective film body and the plane to be protected through the opening, thereby breaking the vacuum state and making the protective film easier to be torn up. However, this structure cannot solve the problem that the existing protective film needs to add mucosal paper. Summary of the Utility Model

Detailed implementation manners

[0030] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] As described in the background art, for the existing display module in the prior art, in the production process of the existing display module, a variety of adhesive materials are used, such as upper and lower polarizers, OCA glue, graphite sheets, double-sided adhesives, etc. These adhesive materials are wrapped by two layers of protective films, and the outer shape design of the protective film is the same as that of the material. When pasting, it is necessary to stick the mucosal paper to the protective film surface at any corner of the material surface, and then tear up the protective film and paste it. When it is necessary to paste another material, another protective film needs to be torn off. With the upgrade of the product, the four corners of the display module are made into R-angle arc shapes, and it is more difficult to tear the protective film starting from the arc position, which affects the production efficiency. Moreover, tearing the protective film requires adding mucosal paper, which will increase the processing cost.

[0032] To solve this technical problem, the present utility model provides a protective film structure 1 for adhesive materials, which includes an adhesive layer body 11. A front protective film 12 is provided on the upper surface of the adhesive layer body 11. A first protective film tearing handle 121 is provided at the edge of the front protective film 12. A back protective film 13 is provided on the lower surface of the adhesive layer body 11. A second protective film tearing handle 131 is provided at the edge of the back protective film 13. The first protective film tearing handle 121 is yellow, and the second protective film tearing handle 131 is pink.

[0033] Through the above structural design, since the first protective film tearing handle 121 is yellow and the second protective film tearing handle 131 is pink, the user can quickly distinguish the front and back sides of the protective film structure 1 for adhesive materials. After the front protective film 12 and the back protective film 13 are torn off, the first protective film tearing handle 121 and the second protective film tearing handle 131 are also torn off accordingly, which will not affect the product and does not require additional mucosal paper. The protective film of the material can be quickly torn off, saving the material cost and improving the production efficiency.

[0034] To enable those skilled in the art to better understand the solution of the present utility model, the following will, in conjunction with the accompanying drawings, elaborate on the technical solutions in the embodiments of the present utility model, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0035] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0036] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0037] As Figure 1 and Figure 2 shown, the protective film structure 1 of the adhesive material includes an adhesive layer body 11. A front protective film 12 is provided on the upper surface of the adhesive layer body 11. A first protective film tearing handle 121 is provided at the edge of the front protective film 12. A reverse protective film 13 is provided on the lower surface of the adhesive layer body 11. A second protective film tearing handle 131 is provided at the edge of the reverse protective film 13. The first protective film tearing handle 121 is yellow, and the second protective film tearing handle 131 is pink. The width of the first protective film tearing handle 121 is greater than that of the second protective film tearing handle 131.

[0038] It should be noted that the thickness of the front protective film 12 and the reverse protective film 13 is 0.06 mm to 0.09 mm.

[0039] In addition, the film tearing voltage of the front protective film 12 and the reverse protective film 13 is ≤500V, and the surface impedance of the front protective film 12 and the reverse protective film 13 is 10^9Ω to 10^11Ω.

[0040] In addition, the length of the first protective film tearing handle 121 is equal to that of the second protective film tearing handle 131.

[0041] In addition, a matte layer 1211 is provided on the surface of the first protective film tearing handle 121.

[0042] The following describes the working mode of this embodiment.

[0043] Since the first protective film tearing handle 121 is yellow and the second protective film tearing handle 131 is pink, the user can quickly distinguish the front and back sides of the protective film structure 1 of the adhesive material. After the front protective film 12 and the reverse protective film 13 are torn off, the first protective film tearing handle 121 and the second protective film tearing handle 131 are also torn off accordingly, which will not affect the product and does not require additional adhesive paper. The material protective film can be quickly torn off, saving material costs and improving production efficiency.

[0044] like Figure 5 As shown, the adhesive material protective film structure provided in Example 1 is further optimized. Specifically, the length of the first protective film tearing handle 121 is greater than that of the second protective film tearing handle 131.

[0045] The working mode of this embodiment is described below.

[0046] Since the length of the first protective film tearing handle 121 is greater than that of the second protective film tearing handle 131, the user can quickly distinguish the front and back sides of the adhesive material protective film structure 1 by length comparison, further improving production efficiency. In addition, due to the different lengths, it is not easy to cause interference when tearing the film, which is convenient for operation.

[0047] like Figure 6 , Figure 7 As shown, the adhesive material protective film structure provided in Example 1 or 2 is further optimized. Specifically, both sides of the first protective film tearing handle 121 and the second protective film tearing handle 131 are provided with extended reinforcement sheets 140.

[0048] It should be noted that the hardness of the extended reinforcement sheet 140 is greater than that of the first protective film tearing handle 121 and the second protective film tearing handle 131 .

[0049] In addition, the extended reinforcing sheet 140 is triangular in shape.

[0050] like Figure 8 As shown, the extended reinforcement sheet 140 is provided with an indication notch 150 .

[0051] The working mode of this embodiment is described below.

[0052] By using the triangular extension reinforcement sheet 140, when tearing the film, the bottom of the first protective film tearing handle 121 and the second protective film tearing handle 131 are not easy to crack and fail, and are more likely to separate from the adhesive layer body. At the same time, the user can use less force to complete the film tearing, and the operation is easy. By using the indicator notch 150 on the extension reinforcement sheet 140, the user can quickly distinguish the front and back sides of the adhesive material protective film structure 1 and the correct film sticking direction, further simplifying the operation.
