Description

Technical Field

[0001] This utility model relates to the field of packaging device technology, and more specifically, to a glass mold assembly and tool kit for film lamination. Background Technology

[0002] like Figure 1 As shown, the current method of film lamination is to stack the glass 400, release film 200, film 300, release film 200 and glass 400 in that order. When the glass, release film and film are placed on the laminator platform, the release film and glass will slide and shift, requiring manual readjustment, which is inconvenient to operate.

[0003] In addition, for aging tests of the space structure between the UV lamp and the test sample (not the type where the sample surrounds the UV lamp), it is necessary to cut the sample separately and clamp it with double-layer glass before wrapping the edges, which is a cumbersome operation.

[0004] Therefore, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a glass mold assembly and tool kit for film lamination, which aims to improve at least one of the problems mentioned in the background art.

[0006] The embodiments of this utility model can be implemented as follows: In a first aspect, this utility model provides a glass mold assembly for film lamination, including an upper glass mold and a lower glass mold; The upper glass mold includes an upper mold body and a boss disposed on one side of the upper mold body; The lower glass mold includes a lower mold body and a molding groove formed on one side of the lower mold body; The boss is used to be embedded into the molding groove during operation to laminate the adhesive film. A through gap is formed between the peripheral wall of the boss and the side wall of the molding groove to accommodate the adhesive film and the release film.

[0007] In an optional embodiment, a recessed groove is formed around the edge of the bottom of the molding groove.

[0008] In an optional implementation, the width of the recess is 1-3 mm.

[0009] In an optional embodiment, the height of the boss is less than the depth of the molding groove, and the difference between the height of the boss and the depth of the molding groove is 0.1~0.6mm.

[0010] In an optional embodiment, the side of the upper mold body with the boss is surrounded by a first frosted part. The side of the lower mold body with the molding groove has a second frosted part around the molding groove; The location of the first frosted part matches the location of the second frosted part.

[0011] In an optional embodiment, the width of the first frosted portion and the second frosted portion is 3 to 8 mm.

[0012] In an optional implementation, both the molding groove and the boss are square.

[0013] In an optional embodiment, the width of the membrane gap is 2~6mm.

[0014] Secondly, this utility model provides a tool kit for film lamination, including two release films with an area larger than the molding groove and a glass mold assembly provided in this utility model.

[0015] The beneficial effects of this utility model include: The specific structural design of the upper and lower glass molds makes them easy to use. During film lamination, there is no need to worry about the slippage of the release film and glass. For aging tests of the space structure between the UV lamp and the test sample (not the sample surrounding the UV lamp type), the mold can be directly used as a sample carrier accessory, eliminating the tedious process of separately cutting the sample, clamping the sample with double-layer glass, and then wrapping the edges.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] like Figures 2 to 5 As shown, the present invention provides a glass mold assembly 100 for laminating adhesive film 300, which includes an upper glass mold 110 and a lower glass mold 120. The upper glass mold 110 includes an upper mold body 111 and a boss 112 disposed on one side of the upper mold body 111; The lower glass mold 120 includes a lower mold body 121 and a molding groove 122 formed on one side of the lower mold body 121; The boss 112 is used to be embedded into the molding groove 122 during operation to laminate the adhesive film 300. A through gap is formed between the peripheral wall of the boss 112 and the side wall of the molding groove 122 to accommodate the adhesive film 300 and the release film 200.

[0026] The method of using the glass mold assembly 100 provided by this utility model is as follows: First, a release film 200 with an area larger than the molding groove 122 is placed inside the molding groove 122. Then, an adhesive film 300 is laid inside the groove. Next, a release film 200 with an area smaller than the molding groove 122 is placed on the surface of the adhesive film 300. Finally, the protrusion 112 of the upper glass mold 110 is inserted into the molding groove 122 with the protrusion facing down, and the laminator is started to laminate the adhesive film 300. After lamination, the upper glass mold 110 is moved up, the upper release film 200 is peeled off, and the laminated adhesive film 300 is cut along the bottom edge of the molding groove 122 using a cutter. The lower release film 200 is then peeled off. During non-sample surrounding UV lamp aging tests, the UV lamp 500 is placed below the lower glass mold 120, and the UV light shines from bottom to top through the lower glass mold 120 onto the adhesive film 300.

[0027] The glass 400 film assembly provided by this utility model is easy to use, and there is no need to worry about the sliding displacement of the release film 200 and the glass 400 during operation. For aging tests of the ultraviolet lamp and the upper and lower spatial structure of the test sample (non-sample surrounding ultraviolet lamp type), the mold can be directly used as a sample carrier accessory, saving the tedious process of separately cutting the sample, clamping the sample with double-layer glass 400 and then wrapping the edges.

[0028] Optionally, a recessed groove 124 is formed around the edge of the bottom of the molding groove 122.

[0029] When cutting the laminated film 300, a tool is used to cut along the bottom edge of the molding groove 122. The tip of the blade can be inserted into the recess 124 during cutting, making the cutting process more convenient.

[0030] Optionally, the slit width a of the recess 124 is 1~3mm.

[0031] When the recess 124 is set within this width range, it enables better cutting of the adhesive film 300.

[0032] Optionally, the height H1 of the boss 112 is less than the depth H2 of the molding groove 122, and the difference h between the height of the boss 112 and the depth of the molding groove 122 is 0.1~0.6mm.

[0033] The sum of the thicknesses of the two release films 200 and the adhesive film 300 is within the above range. Therefore, the difference between the height of the boss 112 and the depth of the molding groove 122 is set to be within this range, so that during lamination, the upper mold body 111 around the boss 112 and the lower mold body 121 around the molding groove 122 fit together perfectly.

[0034] Optionally, the width l of the interlayer gap is 2~6mm. Since the areas of the adhesive film 300 and the release film 200 are larger than the molding groove 122 during lamination, in order for the boss 112 to be smoothly embedded into the molding groove 122, the lateral size of the boss 112 should be smaller than the lateral size of the molding groove 122. When the width of the interlayer gap between the two is 2~6mm, it is convenient for the boss 112 to be embedded into the molding groove 122 when the adhesive film 300 and the two layers of release film 200 are present.

[0035] Optionally, the side of the upper mold body 111 with the boss 112 is surrounded by the boss 112 and is a first frosted part 113; the side of the lower mold body 121 with the molding groove 122 is surrounded by the molding groove 122 and is a second frosted part 123; the positions of the first frosted part 113 and the second frosted part 123 are matched.

[0036] During lamination, the first frosted part 113 and the second frosted part 123 are bonded together. Since both are frosted structures, their bonding has excellent sealing performance, which is equivalent to sealing the edge of the adhesive strip. Compared with the conventional smooth surface glass 400, which fixes the sample and then wraps the edge, it can better prevent moisture intrusion during the ultraviolet damp heat aging process and effectively avoid the impact of moisture intrusion on the test results.

[0037] Optionally, to further ensure good sealing performance, the width L of the first frosted portion 113 and the second frosted portion 123 is 3~8mm.

[0038] Optionally, both the molding groove 122 and the boss 112 are square. Square is a common shape for laminated adhesive film 300. It should be noted that the shape is not limited, and the molding groove 122 can be selected and set to a suitable shape according to actual needs.

[0039] In summary, the glass 400 film assembly provided in this embodiment is easy to use, and there is no need to worry about the sliding displacement of the release film 200 and the glass 400 during operation. For aging tests of the ultraviolet lamp and the upper and lower spatial structure of the test sample (non-sample surrounding ultraviolet lamp type), the mold can be directly used as a sample carrier accessory, saving the tedious process of separately cutting the sample, clamping the sample with double-layer glass 400 and then wrapping the edges.

[0040] In a preferred embodiment, the recess 124 facilitates the cutting of the laminated film 300.

[0041] In a preferred embodiment, the first frosted portion 113 and the second frosted portion 123 provide better sealing between the upper glass mold 110 and the lower glass mold 120, which can better prevent moisture intrusion during ultraviolet damp heat aging and effectively avoid the impact of moisture intrusion on the test results.

[0042] This embodiment of the invention also provides a tool kit for laminating adhesive film 300, including two release films 200 with an area larger than the molding groove 122 and a glass mold assembly 100 provided in this embodiment of the invention. Because it includes the glass mold assembly 100 provided in this embodiment of the invention, it also possesses the advantages of the glass mold assembly 100.

[0043] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
