Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display backlight detection, in particular to a liquid crystal display backlight detection bracket. Background Technique

[0002] A liquid crystal display is an active matrix liquid crystal display driven by thin film transistors. It mainly uses an electric current to stimulate liquid crystal molecules to generate dots, lines, and planes, and cooperates with a backlight tube at the back to form an image. IPS, TFT, and SLCD all belong to the subclasses of LCD. Its working principle is that under the action of an electric field, a backlight source is used to make the liquid crystal display emit light. The backlight source is a light source located behind the liquid crystal display, and its light-emitting effect will directly affect the visual effect of the liquid crystal display module. The liquid crystal display itself does not emit light. It displays graphics or the result of its modulation of light. Currently, the common backlight sources generally have a relatively single structure and function, poor overall protection effect, and are easily affected by environmental factors. Dust is easily contaminated on its surface, which may damage the overall quality.

[0003] Currently, when detecting a liquid crystal display backlight source, because the liquid crystal display backlight source is very thin, it is easily damaged by external forces during detection and taking. Therefore, it is necessary to set up a detection fixing bracket for fixation to facilitate subsequent detection processes. Most of the current fixing brackets have fixed sizes and cannot be adjusted according to size requirements. Based on this, the utility model designs a liquid crystal display backlight detection bracket to solve the above problems. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: A liquid crystal display backlight detection bracket includes a backlight detection fixing support and a back frame surrounded by the outer ends of the backlight detection fixing support.

[0006] A size positioning component is installed inside the backlight detection fixing support at one end of the backlight detection fixing support. The size positioning component includes a positioning plate, a clamping plate, and an adjusting member;

[0007] The positioning plates are symmetrically and slidably connected inside the back frame on both sides of the backlight detection fixing support. Clamping plates are symmetrically and movably installed at both ends of the back frame. The adjusting members are installed on both sides of the backlight detection fixing support to adjust the length of the positioning plates;

[0008] The liquid crystal display backlight source to be tested is placed in a positioning cavity surrounded by the clamping plates and the positioning plates after size adjustment. The positioning cavity positions the liquid crystal display backlight source to be tested to ensure that there is no position shift during subsequent detection.

[0009] Preferably, the adjusting member includes a bidirectional threaded rod, a thin transmission belt, and a positioning groove;

[0010] Both sides of the back frame are symmetrically and rotatably connected with a bidirectional threaded rod. The two bidirectional threaded rods are connected by a thin transmission belt. The positioning plate is threadedly connected with the bidirectional threaded rod, and one end of the positioning plate is in mutual contact with the backlight detection fixed support.

[0011] Preferably, positioning grooves are symmetrically formed at one end of the back frame, and clamping plates are installed on the positioning grooves. Both ends of the clamping plates are symmetrically fixed to the back frame by fixing bolts connected by threads, and a handle is installed on the clamping plates.

[0012] Preferably, a handle is installed on the clamping plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] By providing a size positioning component, it is possible to facilitate the positioning of the positions of liquid crystal display backlights of different sizes. According to the specific size of the liquid crystal display backlight, the size of the positioning cavity is adjusted, thereby reducing the difficulty of positioning liquid crystal display backlights of different sizes, and thus improving the stability of taking the liquid crystal display backlight for subsequent detection processes. When detecting the liquid crystal display backlight after positioning and fixing, the damage to the liquid crystal display backlight caused by external forces can be greatly reduced.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2 The utility model provides a technical solution: a liquid crystal display backlight source detection bracket, comprising a backlight source detection fixed support 1 and a back frame 2 surrounded by the outer end of the backlight source detection fixed support 1, characterized in that:

[0023] A size positioning component 3 is installed inside the backlight source detection fixing support 1 at one end of the backlight source detection fixing support 1. The size positioning component 3 includes a positioning plate 302, a clamping plate 305 and an adjusting member;

[0024] In a further embodiment, the adjusting member includes a bidirectional threaded rod 301, a thin transmission belt 303 and a positioning slot 304;

[0025] The two sides of the back frame 2 are symmetrically rotated to connect the two-way threaded rods 301, and the two two-way threaded rods 301 are connected by a thin transmission belt 303. The positioning plate 302 and the two-way threaded rods 301 are connected by threads, and one end of the positioning plate 302 and the backlight source detection fixed support 1 are in contact with each other.

[0026] A positioning groove 304 is symmetrically provided at one end of the back frame 2, and a clamping plate 305 is installed on the positioning groove 304. The two ends of the clamping plate 305 are symmetrically fixed to the back frame 2 by fixing bolts 306 connected by threads, and a handle 307 is installed on the clamping plate 305. The handle 307 is installed on the clamping plate 305, and by pulling the handle 307, the handle 307 drives the clamping plate 305 to be quickly taken.

[0027] The back frame 2 is internally provided with symmetrically slidingly connected positioning plates 302 at both sides of the backlight source detection fixed support 1. Clamping plates 305 are symmetrically and movably installed at both ends of the back frame 2. Adjusting parts are installed at both sides of the backlight source detection fixed support 1 to adjust the length of the positioning plates 302.

[0028] The LCD backlight source to be tested is placed in a positioning cavity surrounded by the clamping plate 305 and the positioning plate 302 after adjusting the size. The positioning cavity positions the LCD backlight source to be tested to ensure that there is no position shift during subsequent testing.

[0029] Before performing corresponding tests on the liquid crystal display backlight to be tested, adjust the size positioning component 3 according to the specific size of the liquid crystal display backlight to be tested. By rotating the bidirectional threaded rod 301, when the bidirectional threaded rod 301 rotates, it drives the thin transmission belt 303 to move. When the thin transmission belt 303 moves, it drives another bidirectional threaded rod 301 to rotate. Since the bidirectional threaded rod 301 is threadedly connected to the positioning plate 302, when the two bidirectional threaded rods 301 rotate, they can synchronously drive the positioning plate 302 to move. When the two positioning plates 302 are moved to the same size of the liquid crystal display backlight to be tested, this process can be measured for length by an external measuring ruler. Stop rotating the bidirectional threaded rod 301, thereby positioning the position of the positioning plate 302. Place the clamping plate 305 into the positioning groove 304 and fix it through the fixing bolt 306 at the top of the clamping plate 305 to prevent the liquid crystal display backlight to be tested from falling out. When it is not necessary to move the liquid crystal display backlight detection bracket, the clamping plate 305 can be not covered, and it is not necessary to fix the clamping plate 305 through the fixing bolt 306.

[0030] In the positioning cavity formed by the clamping plate 305 and the positioning plate 302 after adjusting the size, the positioning cavity positions the liquid crystal display backlight to be tested to ensure that there is no position shift during subsequent tests. By adjusting the position of the positioning plate 302, it is convenient to position the positions of liquid crystal display backlights of different sizes, thereby reducing the difficulty of positioning the device for liquid crystal display backlights of different sizes, improving the stability during the detection of liquid crystal display backlights, and improving the stability of taking the liquid crystal display backlight for subsequent detection processes. When detecting the positioned and fixed liquid crystal display backlight, the damage to the liquid crystal display backlight caused by external forces can be greatly reduced.
