Description

Technical Field

[0001] The utility model belongs to the technical field of LCD display manufacturing, and particularly relates to a fixture for manufacturing an LCD display with adjustable insertion and placement spacing. Background Technique

[0002] An LCD forms a liquid crystal layer between two parallel glass substrates, then a color filter is provided on the upper substrate glass, thin film transistors and an LED backlight are provided on the lower substrate glass. By changing the voltage on the thin film transistors, the opening and closing degree of the liquid crystal molecules in the liquid crystal layer is controlled. The larger the opening and closing degree, the more light is emitted, and the smaller the opening and closing degree, the less light is emitted. In this way, the amount of white light can be controlled to achieve the purpose of adjusting the ratio of red, green, and blue, and further control the emission of polarized light from each pixel point to achieve the display purpose. During the manufacturing process of an LCD display, the display needs to be tested, and a clamping and fixing bracket is required to clamp and fix the display.

[0003] Most of the existing fixed fixtures are fixed on the processing platform and can only clamp and fix displays of the same size. They cannot be adjusted according to the size of the LCD display, and cannot clamp and fix displays of different specifications, which affects the applicable range of the fixture. Moreover, only one side of the display can be detected. When it is necessary to detect the other side, the staff needs to disassemble the display, flip it, and then fix it on the fixture to detect the other side. The operation steps are cumbersome and affect the detection efficiency.

[0004] Therefore, a fixture for manufacturing an LCD display with adjustable insertion and placement spacing is needed to solve the problems in the prior art that displays of different specifications cannot be clamped and fixed and the display cannot be driven to flip. Summary of the Utility Model

The installation table is arranged above the rotating mechanism. The clamping mechanism is arranged inside the installation table. The fixing mechanism is symmetrically arranged above the clamping mechanism. The placement mechanism is arranged in the middle above the installation table.

[0007] It should be noted in the solution that the clamping mechanism is composed of a rotating plate, a connecting rod, a connecting block, a rectangular block, a slider and a cylinder.

The convex blocks are symmetrically fixedly connected to the upper and lower ends of the fixing plate, and are slidably connected to the inside of the fixing frame through the convex blocks.

[0009] Even further, it should be noted that the sliding rod is fixedly connected to the middle of one side of the fixing plate, and the sliding rod is slidably connected to both sides of the fixing frame. The fixing plate is symmetrically fixedly connected between the convex block and the inner wall of the fixing frame.

[0010] As a preferred implementation manner, the placing mechanism is composed of a U-shaped block, a threaded rod and a clamping block.

[0012] As a preferred implementation manner, the limiting shafts are symmetrically fixedly connected to the bottom surface of the mounting table, and an annular groove adapted to the limiting shafts is formed on the workbench.

[0013] As a preferred implementation manner, anti-slip layers are provided on one side of both the fixing plate and the clamping block.

Detailed Embodiment

[0023] The following further describes the present utility model in conjunction with embodiments.

[0024] Please refer to Figures 1-5 , the present utility model provides a fixture for manufacturing an LCD display screen with adjustable insertion spacing, including a workbench 1, support legs 2, a rotating mechanism 3, an installation table 4, a clamping mechanism 5, a fixing mechanism 6 and a placing mechanism 7. The support legs 2 are symmetrically and fixedly connected to the lower part of the workbench 1. The rotating mechanism 3 is arranged below the middle of the workbench 1. The installation table 4 is arranged above the rotating mechanism 3. The clamping mechanism 5 is arranged inside the installation table 4. The fixing mechanism 6 is symmetrically arranged above the clamping mechanism 5. The placing mechanism 7 is arranged in the middle above the installation table 4.

[0025] Further, as shown in Figure 1 , Figure 2 and Figure 3 it is worth specifically stating that the clamping mechanism 5 is composed of a rotating plate 501, a connecting rod 502, a connecting block 503, a rectangular block 504, a slider 505 and a cylinder 507. The rotating plate 501 is rotatably connected to the inside of the mounting table 4. The connecting rods 502 are symmetrically and rotatably connected to both ends of the rotating plate 501. The rectangular block 504 is fixedly connected to one side of the connecting block 503. The slider 505 is fixedly connected above the rectangular block 504. The cylinder 507 is fixedly connected to the right end of the mounting table 4, and the output end of the cylinder 507 is connected to the other side of the rectangular block 504. Chutes 506 are symmetrically formed above the mounting table 4, and the slider 505 is slidably connected to the inside of the chutes 506;

[0026] By driving the rectangular block 504 on one side to move through the cylinder 507, driving the rotating plate 501 to rotate through the connecting block 503 and the connecting rod 502, and at the same time driving the rectangular block 504 to move through the connecting rod 502 and the connecting block 503 on the other side, driving the fixing mechanism 6 above to move towards each other, the distance between the fixing frames 601 can be adjusted to ensure the synchronism of the movement of the fixing frames 601.

[0027] Further, as shown in Figure 1 , Figure 2 and Figure 4 it is worth specifically stating that the fixing mechanism 6 is composed of a fixing frame 601, a fixing plate 602, a convex block 603, a spring 604 and a sliding rod 605. The fixing frame 601 is fixedly connected above the slider 505. The fixing plate 602 is arranged inside the fixing frame 601. The convex blocks 603 are symmetrically and fixedly connected to the upper and lower ends of the fixing plate 602. The convex blocks 603 are slidably connected to the inside of the fixing frame 601. The sliding rod 605 is fixedly connected to the middle of one side of the fixing plate 602, and the sliding rod 605 is slidably connected to both sides of the fixing frame 601. The fixing plate 602 is symmetrically and fixedly connected between the convex block 603 and the inner wall of the fixing frame 601;

[0028] By sliding the provided fixing plate 602, display screens with different thicknesses can be clamped, improving the applicable range of this mechanism.

[0029] Further, as shown in Figure 1 , Figure 2 and Figure 5 it is worth specifically stating that the placing mechanism 7 is composed of a U-shaped block 701, a threaded rod 702 and a clamping block 703. The U-shaped block 701 is fixedly connected to the middle of the upper part of the mounting table 4. The threaded rod 702 is threadedly connected to the front plate of the U-shaped block 701. The clamping block 703 is rotatably connected to the back of the threaded rod 702, and limiting blocks are symmetrically and fixedly connected below the clamping block 703. The limiting blocks are slidably connected to the bottom surface of the U-shaped block 701;

[0030] The set limit block can restrict the clamping block 703 from rotating following the threaded rod 702, ensuring that the clamping block 703 moves linearly to clamp the display screen.

[0031] According to the above working process, it can be known that: by setting the mounting table 4, the clamping mechanism 5, the fixing mechanism 6 and the placing mechanism 7, the distance between the fixing frames 601 can be adjusted according to the size of the LCD display screen, facilitating the clamping and fixing of display screens with different specifications and sizes, and improving the applicable range of this fixture.

[0032] Furthermore, as shown in Figure 1 , Figure 2 and Figure 3 It is specifically noted that the rotating mechanism 3 is composed of a motor 301, a driving gear 302, a driven gear 303, a connecting shaft 304 and a limiting shaft 305. The motor 301 is fixedly connected to the bottom surface of the workbench 1, the driving gear 302 is connected to the output end of the motor 301, the driven gear 303 meshes with the driving gear 302, the connecting shaft 304 is fixedly connected above the driven gear 303, the top end of the connecting shaft 304 is fixedly connected to the bottom surface of the mounting table 4, the limiting shafts 305 are symmetrically and fixedly connected to the bottom surface of the mounting table 4, and an annular groove adapted to the limiting shafts 305 is provided on the workbench 1;

[0033] By setting the limiting shafts 305 to slide inside the annular groove, the stability of the rotation of the mounting table 4 and the upper display screen is ensured.

[0034] Furthermore, as shown in Figure 1 , Figure 2 and Figure 3 It is specifically noted that anti-slip layers are provided on one side of the fixing plate 602 and the clamping block 703;

[0035] By setting the anti-slip layers, the friction force between the fixing plate 602 and the clamping block 703 and the display screen is increased, further ensuring the stability of clamping and fixing.

[0036] This solution has the following working process: When in use, first place the display screen inside the U-shaped block 701, then rotate the threaded rod 702 to drive the clamping block 703 to move until the clamping block 703 approaches the outer wall of the display screen, initially positioning the position of the display screen. Then start the cylinder 507 to push the rectangular block 504 to slide, drive the rotating plate 501 to rotate through the connecting rod 502, and at the same time drive the rectangular block 504 to move towards each other through the connecting rod 502 on the other side. At the same time, pull the sliding rod 605 outwards until the inner wall of the fixing frame 601 is close to the outer walls on both sides of the display screen. Release the sliding rod 605, and drive the fixing plate 602 to reset under the elastic action of the spring 604, further clamping and fixing the display screen to ensure the stability of the display screen and facilitate the detection of the display screen. After the detection is completed, start the motor 301 to drive the driving gear 302 to rotate, drive the connecting shaft 304 to rotate through the driven gear 303, and drive the upper display screen to rotate through the mounting table 4, facilitating the detection of the other side of the display screen and improving the detection efficiency.

[0037] In summary: By setting the mounting table 4, the clamping mechanism 5, the fixing mechanism 6, and the placement mechanism 7, the distance between the fixing frames 601 can be adjusted according to the size of the LCD display screen, facilitating the clamping and fixing of display screens of different specifications and sizes, and improving the applicable range of this fixture; by setting the rotating mechanism 3, when the detection of one side of the display screen is completed, the display screen is automatically driven to flip, and the other side is detected without manual flipping, with convenient operation and improved detection efficiency.
