[0002] Backlight film is a component used in liquid crystal displays. It is located on the back of the LCD screen. Its main function is to provide backlight so that the LCD screen can display images. Backlight film usually includes several parts such as light source, reflective film, light guide plate and polarizer. Their structure and material will affect the display effect of the LCD screen. When processing the LCD screen, the LCD module and the backlight module need to be bonded, so an assembly device is needed.

[0003] The existing assembly device usually adheres the backlight film to the liquid crystal module by pressing, so that the two are in close contact, ensuring the activation rate of the backlight module after adhesion. However, the liquid crystal module cannot be well fixed during pressing, which causes the liquid crystal module to move, thereby affecting the pressing effect of the backlight film and causing damage to the liquid crystal module. At the same time, the dust on the backlight film during pressing will affect the display effect of the screen, thereby reducing the product quality. In view of the above problems, a backlight film assembly device is proposed by a person skilled in the art to solve the above problems. Utility Model Content

[0022] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a backlight film assembly device, including a processing table 1, a plurality of support columns 2 are fixedly connected to the top of the processing table 1, a top plate 3 is fixedly connected to the top of the plurality of support columns 2, a motor 4 is fixedly connected to the front left side of the top plate 3, the left and right sides of the inside of the top plate 3 are rotatably connected to a two-way threaded rod 5, the external threads of the two-way threaded rod 5 are connected to two threaded blocks 6, the bottom of the threaded block 6 is rotatably connected to a connecting rod 7, and the bottom ends of the two connecting rods 7 are rotatably connected to a pressing plate 8.

[0023] The top of the top plate 3 is fixedly connected with a dust removal box 14, and a filter plate 18 is installed inside the dust removal box 14 through a snap-on assembly. A pressing assembly is installed below the top plate 3.

[0024] One end of the left bidirectional threaded rod 5 is fixedly connected to the output end of the motor 4, and the other ends of the two motors 4 are fixedly connected to pulleys 9, and the two pulleys 9 are connected by a belt.

[0025] The processing table 1 is connected to multiple support columns 2, so that the multiple support columns 2 support the top plate 3 at the top, and the motor 4 is fixed through the top plate 3, so that the motor 4 can drive the bidirectional threaded rod 5 connected to it to rotate during operation, thereby causing the pulley 9 connected to the other end of the bidirectional threaded rod 5 to rotate, and the pulley 9 connected to one end of the right-hand bidirectional threaded rod 5 rotates driven by the belt, thereby causing the right-hand bidirectional threaded rod 5 to rotate synchronously.

[0026] The rotation of the bidirectional threaded rod 5 causes the two externally connected threaded blocks 6 to move. Since the two threaded blocks 6 are symmetrically arranged, they will approach each other when the bidirectional threaded rod 5 rotates, and drive the connecting rod 7 to move, and then push the pressing plate 8 downward through the two connecting rods 7 to fix the liquid crystal module. When the backlight film and the liquid crystal module are assembled, it is not easy to move, and a protective pad is arranged at the bottom of the pressing plate 8 to ensure that the liquid crystal module will not be damaged. The absorbed dust can be processed by the dust removal box 14 and filtered by the filter plate 18 to extend the service life of the device.

[0027] Reference Figure 3 and Figure 4 The clamping assembly includes two limit slots 19, which are respectively opened on the left and right sides of the filter plate 18. The limit slots 19 are fixedly connected to the limit blocks 20. The other end of the limit blocks 20 is fixedly connected to a spring 21. The adjacent sides of the two springs 21 are fixedly connected to a pull rope 22. The other side of the spring 21 is fixedly connected to a clamping block 23.

[0028] Two slots 24 are provided on the inner side of the dust removal box 14 . The adjacent ends of the two pull ropes 22 are fixedly connected with a rotating handle 25 . The bottom of the rotating handle 25 is rotatably connected to the inside of the filter plate 18 .

[0029] The outside of the spring 21 is slidably connected to the inside of the limiting groove 19. The outside of the clamping block 23 is clamped to the inside of the clamping groove 24 on one side.

[0030] Rotating the handle 25 can drive the two pull ropes 22 to reel up, so that the other end of the pull rope 22 drives the limit block 20 to slide inside the limit groove 19. The limit groove 19 can limit the limit block 20 to keep it moving horizontally, ensuring the stable operation of the structure. When moving, the limit block 20 will compress the spring 21, so that the block 23 will be separated from the slot 24, so that the filter plate 18 can be disassembled, which is convenient for replacement or cleaning and prolongs the service life of the device. When installing the filter plate 18, after loosening the handle 25, the spring 21 will generate a rebound force to push the limit block 20 to move, so that the block 23 enters the slot 24 to complete the engagement, and the filter plate 18 is fixed.

[0031] Reference Figure 1 The pressing assembly includes two electric slide rails 10, both of which are installed under the top plate 3. The outside of the electric slide rails 10 is fixedly connected to an electric telescopic rod 11 through an electric slider. The output ends of the two electric telescopic rods 11 are fixedly connected to a mounting seat 12, and the inner side of the mounting seat 12 is rotatably connected to a rolling wheel 13.

[0032] Two electric slide rails 10 respectively drive an electric telescopic rod 11 to move, and the two electric telescopic rods 11 drive the mounting seat 12 to move horizontally, and push the mounting seat 12 to move downward so that the rolling wheel 13 fits the backlight film above the liquid crystal module, and the liquid crystal module and the backlight film are pressed together to realize the assembly of the backlight film.

[0033] Reference Figure 1 A fan 15 is fixedly connected to the top of the top plate 3, and the output end of the fan 15 is fixedly connected to the outside of the dust removal box 14. A connecting pipe 16 is fixedly connected to the left side of the outside of the dust removal box 14, and the other end of the connecting pipe 16 is fixedly connected to a dust hood 17, which is fixedly connected to the inner top of the mounting base 12.

[0034] The operation of the fan 15 can generate airflow, so that the dust adhered to the surface of the rolling wheel 13 enters the connecting pipe 16 through the dust hood 17 when it rolls, and then enters the dust removal box 14 after being transported through the connecting pipe 16, so as to process the dust and avoid the situation where the dust is not tightly adhered to the backlight film and becomes detached during lamination, thereby improving the production quality.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
