DETAILED DESCRIPTION

[0025] The present application aims to provide an assembling device, which can ensure the alignment of the optical film and the diffusion plate, and avoid the problems of wrinkles and misalignment of the optical film.

[0026] To make the objectives, technical solutions and effects of the present application clearer and more explicit, the present application is further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0027] Please refer to Figure 1 The present application provides an assembling device, which comprises a fixed frame 10, a support plate 20 arranged on the fixed frame 10 and used for laying a diffusion plate, the diffusion plate being stacked with an optical film, and a support mechanism 40 arranged on the fixed frame 10 and used for abutting against the support plate 20 to support the support plate 20 to form an inclined surface, the inclined surface being inclined along a first end of the support plate 20 towards a second end, the height of the second end being lower than that of the first end, and the second end being provided with a first baffle 31, so that the diffusion plate and the optical film on the support plate 20 are aligned along the inclined surface towards the first baffle 31. In the present example, a part of the support plate 20 is attached to the fixed frame 10, and the other part of the support plate 20 is away from the fixed frame 10 under the support of the support mechanism 40. Therefore, the support plate 20 forms an inclined surface on the fixed frame 10. In the present example, when the assembling device is used to combine the diffusion plate and the optical film, the diffusion plate is first placed on the inclined support plate 20, and then the diffusion plate is aligned towards the first baffle 31 under the action of gravity, and then the optical film is placed on the diffusion plate along the position of the first baffle 31, and the optical film is gently pulled away from the first baffle 31, and then the optical film is aligned with the first baffle 31 according to its own gravity, so as to ensure the alignment of the optical film and the diffusion plate, and avoid the problems of wrinkles and misalignment of the optical film.

[0028] In some embodiments, the inclined surface further inclines towards the fourth end from the third end, the fourth end is lower than the third end, and the fourth end is provided with a second baffle 32, wherein the fourth end and the second end are adjacent, and the diffusion plate and the optical film on the supporting plate 20 are aligned towards the first baffle 31 and the second baffle 32 along the inclined surface. Compared with the case where only one baffle is provided, the provision of two baffles in this embodiment can ensure that the four sides of the optical film are aligned with the diffusion plate. Specifically, the two baffles are provided at two adjacent ends, that is, the first baffle 31 and the second baffle 32 in this embodiment extend to form an "angle", and the diffusion plate and the optical film can be inclined towards the "angle" along the inclined surface, so as to ensure that the two adjacent ends of the diffusion plate and the optical film are aligned towards the first baffle 31 and the second baffle 32, respectively, and further ensure that the four sides of the optical film are aligned with the diffusion plate, thereby avoiding the problems of wrinkles and misalignment of the optical film.

[0029] Further, please refer to Figure 2 , the fixing frame 10 comprises a supporting frame 11, and a limiting groove is arranged in the supporting frame 11. The supporting frame 11 in this embodiment is square, and the limiting groove is arranged in the supporting frame 11. The limiting groove can be arranged along the entire supporting frame 11, which is equivalent to that the limiting groove forms a square around. In this embodiment, the supporting mechanism 40 comprises at least one supporting rod 41, one end of the supporting rod 41 is arranged in the limiting groove, and the other end of the supporting rod 41 abuts against the supporting plate 20; the supporting rod 41 adjusts the inclination angle of the supporting plate 20 by moving in the limiting groove. The supporting rod 41 can be provided with one or more. If the supporting rod 41 is provided with multiple, one can be arranged at each of the four edges of the square supporting frame 11, thereby forming multiple supporting points for the supporting plate 20, and further ensuring the stability of the supporting plate 20. Since the supporting rod 41 is movably arranged in the limiting groove, the supporting rod 41 can move along the limiting groove, and thus the inclination angle of the supporting plate 20 can be changed by changing the supporting point of the supporting plate 20, thereby improving the flexibility of the inclined surface adjustment.

[0030] Further, the first end and the third end of the supporting plate 20 are each attached with a baffle 50. The supporting plate 20 in this embodiment is a square supporting plate 20, one set of adjacent two ends of the supporting plate 20 is provided with the first baffle 31 and the second baffle 32, respectively, and the other set of adjacent two ends of the supporting plate 20 is provided with the baffles 50, the number of the baffles 50 is multiple, and the baffles 50 are arranged at intervals on the edges of the supporting plate 20. By arranging the baffles 50 on the edges of the supporting plate 20, the baffles 50 can play a certain positioning role when the diffusion plate or the optical film is placed, and further ensure that the four sides of the diffusion plate are aligned with the optical film.

[0031] Further, please refer to Figure 3The supporting plate 22 is a transparent glass plate. When the optical film sheet is pasted on the diffusion plate, the light source 70 in the supporting plate 22 can be turned on to check the quality of the diffusion plate and the optical film sheet.

[0032] In the embodiment, the supporting plate 22 can be a tempered glass plate. The friction coefficient of the tempered glass plate is low, so that the surface of the supporting plate 22 is smoother, thereby effectively avoiding abrasion or scratching of the diffusion plate and the optical film sheet.

[0033] In the embodiment, the first adhesive strip 61 and the second adhesive strip 62 are transparent silica gel strips. On the one hand, the transparent silica gel strips can make the light source 70 in each space transparent through the side surface, so that the entire supporting plate 20 is lit when the light source 70 is turned on, thereby facilitating the checking of the assembly of the diffusion plate and the optical film sheet. On the other hand, the transparent silica gel strips can ensure that the supporting plate 22 is better fixed and attached to the bottom plate 21, thereby improving the stability of the supporting plate 20.

[0034] In some embodiments, referring to Figure 4 The assembly device further comprises a pressing structure 80. The pressing structure 80 comprises a first pressing portion 81 and a second pressing portion 82 arranged opposite to the first pressing portion 81. The first pressing portion 81 and the second pressing portion 82 are connected by a connecting portion 83 and form a slot A. The pressing structure 80 is connected to the first baffle 31 and / or the second baffle 32 through the slot A, so that the first pressing portion 81 abuts against the optical film sheet on the supporting plate 20. The optical film sheet is pressed by moving the pressing structure 80 along the first baffle 31 and / or the second baffle 32. In the embodiment, the pressing structure 80 can be arranged on both the first baffle 31 and the second baffle 32, or on one of the baffles. The embodiment does not limit this, and the arrangement can be made according to actual needs.

[0035] The pressing structure 80 in the embodiment is similar to a "clip" and is clamped on the baffle through the connecting part 83 connecting the opposite first pressing part 81 and the second pressing part 82. The first pressing part 81 is located on the side close to the supporting plate 20, and the second pressing part 82 is located on the side away from the supporting plate 20. After the optical film is attached to the diffuser plate, the pressing structure 80 can be moved back and forth along the baffle, so that the first pressing part 81 abuts against the optical film on the supporting plate 20, and the optical film and the diffuser plate are pressed to ensure that the optical film and the diffuser plate are better fixed and attached.

[0036] Further, the first pressing part 81 is provided with the first roller 84 at the end close to the supporting plate 20. When the optical film and the diffuser plate are pressed by the pressing structure 80, the first roller 84 can be slid back and forth on the diffuser plate with the optical film attached to the diffuser plate, so that the optical film is tightly attached to the diffuser plate, and the optical film and the diffuser plate are prevented from being separated. In addition, the friction between the first pressing part 81 and the diffuser plate can be reduced, and the optical film and the diffuser plate are prevented from being worn.

[0037] Further, the bottom of the fixing frame 10 is also provided with the second roller 90. The fixing frame 10 can be pushed by the second roller 90, so that the position of the fixing frame 10 can be flexibly moved as needed.

[0038] In order to further illustrate the working principle of the assembling device in the present application, the working process of the assembling device is described in detail by combining the diffuser plate and the optical film as follows:

[0039] Before assembling the diffuser plate and the optical film, the inclination angle of the supporting plate 20 is first adjusted by moving one or more supporting rods 41. Then, the diffuser plate with double-sided adhesive tape is placed on the supporting plate 20, and the side with the double-sided adhesive tape is away from the supporting plate 20. Then the diffuser plate is aligned with the two baffles under the action of gravity. Then the dustproof paper on the double-sided adhesive tape of the diffuser plate is removed, and the optical film is placed on the diffuser plate by aligning the two baffles and gently pulling the optical film at the inclination angle. Then, the pressing structure 80 is moved to press the optical film against the double-sided adhesive tape on the diffuser plate, so that the optical film and the diffuser plate are pressed more closely to prevent the optical film from falling off. After the pressing is completed, the light source 70 of the supporting plate 20 is turned on, and light is emitted from the side of the diffuser plate close to the supporting plate 20 to the diffuser plate to check the combination of the diffuser plate and the optical film, and to confirm whether the diffuser plate and the optical film are worn or not. After the inspection is completed, the diffuser plate with the optical film is removed under the condition that the optical film and the diffuser plate are combined well, so as to facilitate the subsequent assembly of the backlight module.

[0040] In summary, the application provides an assembling device, which comprises a fixing frame, a supporting plate arranged on the fixing frame and used for laying a diffusion plate, an optical film piece stacked on the diffusion plate, and a supporting mechanism arranged on the fixing frame and used for abutting against the supporting plate to support the supporting plate to form an inclined surface, the inclined surface being inclined from a first end of the supporting plate to a second end, the height of the second end being lower than that of the first end, and the second end being provided with a first baffle, so that the diffusion plate and the optical film piece on the supporting plate are aligned with the first baffle along the inclined surface, thereby ensuring that the optical film piece is aligned with the diffusion plate and avoiding the generation of problems such as wrinkles and misalignment of the optical film piece.
