Description

Technical Field

[0001] This application belongs to the technical field of liquid crystal modules, and particularly relates to a jig for adjusting the angle of the BL film material of a liquid crystal module. Background Art

[0002] In the existing jig for adjusting the BL angle of a module, the adjustment is mainly based on a BL template and preset upper and lower brightness enhancement films (with angles of 0° / 90° and perpendicular to each other). The specific operation is as follows: First, set the angle of the upper brightness enhancement film, match the corresponding angle of the lower brightness enhancement film, after lighting the BL template, cover the confirmed FOG component (including LCD, POL, and FPC), and then manually rotate the FOG and observe within the plane angle range of 0 - 180° to determine the best viewing and positioning angle. This best angle is obtained by measuring the position of the rotated FOG with a protractor and converting it with the angle of the upper brightness enhancement film on the BL template.

[0003] However, this jig has the following defects:

[0004] 1. The positioning of the FOG depends on manual rotation by workers, with low precision. It requires multiple debugging and confirmation, and it is easy to drive the lighting jig during the rotation process, making the operation inconvenient.

[0005] 2. After determining the best viewing angle, it is not easy to fix the FOG, and additional tape is required for fixing.

[0006] 3. After determining the best angle in the plane, it is also necessary to perform a 360° flip within the plane and a maximum flip of 45° for a second re - judgment and confirmation. Since the BL template is fixedly placed, the flipping operation within the plane is difficult. Summary of the Invention

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0031] In order to illustrate the technical solutions described in the present application, the following will be illustrated through specific embodiments.

[0032] Please refer to Figures 1 to 4As shown in the figure, an angle adjustment fixture for the BL film material of a liquid crystal module provided by an embodiment of the present application includes: a base 1, a supporting plate 3, a turntable 5, and a slider assembly. A pillar 11 is provided on the base 1, and a spherical groove 12 is opened at the top of the pillar 11. A ball head 31 and a first spring 2 located outside the ball head 31 are provided at the bottom of the supporting plate 3, and the supporting plate 3 can thus rotate 360° in the horizontal plane around the spherical groove 12 and adjust the flipping inclination angle within the range of 0 - 45°; a circular ring groove 37 for accommodating the ball 4 is provided on the upper plane of the supporting plate 3, and four scale marks 32 are provided outside the circular ring groove 37. A BL groove for fixedly placing the BL film material 51 is provided on the upper plane of the turntable 5. The turntable 5 is rotationally connected to the center of the supporting plate 3 through a bearing, and an angle marking line is provided at the edge of the turntable 5. The slider assembly is arranged on the turntable 5 and is used for fixedly placing the FOG assembly.

[0033] Among them, a large - scale adjustment knob 35 and a small - scale fine - tuning knob 36 for adjusting the angle, and a fixed switch button 34 for prohibiting the relative rotation between the supporting plate 3 and the turntable 5 are further provided on the supporting plate 3.

[0034] The working principle of the above - mentioned angle adjustment fixture for the BL film material of the liquid crystal module is as follows:

[0035] 1. First, place and fix the BL film material 51, for example, it can be fixed by a light - shielding tape 52. Place and fix the FOG assembly through the slider assembly. For example, the length and width dimensions can be adjusted by the long slider 6, the short slider 7, and the slider groove 33 to adapt to FOG assemblies of different sizes, and then the FOG assembly is fixed by a screw 8 with a spring. For example, in some embodiments, initially, the angle of the upper brightness - enhancement film is set to 0°, and the angle of the lower brightness - enhancement film is set to 90°, which is horizontally aligned with the angle marking line on the turntable 5, and at the same time, readings are taken through the four scale marks 32 on the supporting plate 3.

[0036] 2. Quickly adjust the angle through the large - scale adjustment knob 35 and the small - scale fine - tuning knob 36. For example, relative rotation between the supporting plate 3 and the turntable 5 is realized through a bearing, the height is limited by the ball 4 and the circular ring groove 37, and the angle of the BL film material 51 is quickly adjusted through the large - scale adjustment knob 35 and the small - scale fine - tuning knob 36 at 180° in the horizontal plane; after the angle is adjusted, it is fixed through the fixed switch button 34 to prohibit the rotation between the supporting plate 3 and the turntable 5.

[0037] 3. Through the first spring 2, the ball head 31, and the spherical groove 12 at the top of the pillar 11, 360° rotation in the horizontal plane and adjustment within the range of the flipping inclination angle of 0 - 45° are realized. Among them, the first spring 2 plays a role in connecting the pillar 11 and the turntable 5 for resetting.

[0038] Therefore, a BL film material angle debugging fixture provided by an embodiment of the present application, through the overall cooperation of the supporting plate 3, the turntable 5, and the slider assembly, realizes planar rotation and planar angle flipping through the design of the ball 4, the ball head 31, and the first spring 2, solves the compatibility of FOG placement for different sizes of products, and thus improves the detection efficiency to overcome the defects in the background technology.

[0039] In some embodiments, as Figure 2 shown, the slider assembly includes a long slider 6, a short slider 7 located on the long slider 6, and a screw 8 containing a second spring. The supporting plate 3 is also provided with a slider groove 33 for the long slider 6 to slide. The long slider 6 slides in the slider groove 33, and the short slider 7 slides along the axial direction of the long slider 6, which jointly act to fix FOG components of different sizes.

[0040] In some embodiments, as Figure 2 shown, the surfaces of the long slider 6 and the short slider 7 for placing the FOG component are provided with foam to avoid hard contact and damage to the LCD in the FOG component.

[0041] In some embodiments, as Figure 3 shown, the BL film material 51 includes a reflective film, a light guide plate, a diffusion film, a lower brightness enhancement film, and an upper brightness enhancement film. The lower brightness enhancement film and the upper brightness enhancement film are fixedly connected to the turntable 5 through a light-shielding adhesive.

[0042] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
