Description

Technical Field

[0001] This utility model relates to the field of backlight film assembly technology, and more particularly to an assembly device for backlight film assemblies. Background Technology

[0002] As a core component of LCD displays, the assembly precision of the backlight assembly directly affects the uniformity and brightness of the display effect. With the increasing demand for thinner and lighter displays and higher image quality in the consumer electronics market, the assembly process of the backlight assembly faces higher requirements. In the traditional assembly process, the backlight film needs to be precisely aligned with components such as the light guide plate and reflective film, and fixed by a plastic frame or metal frame. Since different models of displays have different requirements for the size of the backlight film, the assembly device needs to have high versatility and positioning stability. In addition, under the trend of automated production, how to achieve efficient material feeding has also become the key to improving production capacity.

[0003] Most existing backlight film assembly devices adopt a fixed positioning structure, which mechanically limits the backlight film by pre-designed slots or limiting blocks. Some devices use pneumatic grippers or vacuum suction cups in conjunction with servo drives to achieve the gripping and placement of the backlight film.

[0004] The main problem with existing technologies is that they are difficult to flexibly adapt to the positioning requirements of backlight films of different sizes. Due to the wide variety of backlight film sizes, fixed positioning structures require frequent changes of fixtures or adjustments of limiting devices, resulting in low assembly efficiency and easy positioning deviations. Especially in multi-variety, small-batch production, manual intervention not only increases costs but can also damage the backlight film due to operational errors. In addition, traditional positioning methods lack elastic compensation mechanisms and have poor tolerance compatibility with backlight films, which can easily lead to gaps or stress concentrations after assembly, affecting optical performance. Therefore, an assembly device for backlight film assemblies is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an assembly device for backlight film assemblies, which aims to improve the problem of difficulty in positioning backlight films of different sizes within the assembly frame in the prior art.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by pulling the frame, the sliding column and the sliding plate are moved to slide. The sliding plate slides and compresses the first spring. At the same time, the sliding column moves the positioning plate to slide inside the assembly frame. Then, the spring releases the elastic force, thereby achieving the effect of positioning backlight films of different sizes placed inside the assembly frame. This solves the problem of difficulty in positioning backlight films of different sizes inside the assembly frame and improves the versatility and positioning accuracy of backlight film assembly.

[0025] 2. In this utility model, the output end of the electric push rod drives the inclined block and the sliding frame to slide on the fixed block. Then, the inclined side of the inclined block pushes the pulley, causing the pulley to roll on the outer wall of the inclined block. This causes the notch frame and the lifting column and lifting plate above to move upward, thereby achieving the effect of lifting and unloading the assembled backlight module. This solves the problem of inconvenient unloading after the backlight module is assembled and improves the automation level and unloading efficiency of backlight module production.

One end of the spring 11 is fixedly connected to the side wall of the sliding plate 12, and the other end of the spring 11 is fixedly connected to the inner wall of the hollow frame 8. A lifting component is provided inside the assembly frame 2. The lifting component is used to push out the backlight module after assembly for unloading.

[0035] Reference Figures 1-5The lifting assembly includes a lifting plate 4 and a lifting column 16. The lifting plate 4 directly supports and lifts the assembled backlight module. The lifting plate 4 is slidably connected inside the assembly frame 2. The lifting column 16 transmits the lifting force and guides the vertical movement of the lifting plate 4. The top of the lifting column 16 is fixedly connected to the bottom of the lifting plate 4, and the lifting column 16 is slidably connected inside the assembly frame 2. A fixed frame 6 is fixedly connected inside the support frame 1, providing a stable sliding track for the lifting column 16. The lifting column 16 is slidably connected inside the fixed frame 6. A notch frame 18 is fixedly connected to the bottom of the lifting column 16. The notch frame 18 is used to install pulleys 19 and transmit the thrust of the inclined block 14. The pulleys 19 are rotatably connected inside the notch frame 18, reducing frictional resistance with the inclined block 14 and achieving force direction conversion. The outer wall of the lifting column 16 is fitted with... Spring 17 provides a reset force after lifting to return the lifting plate 4 to its initial position.

[0036] Working principle: When positioning backlight films of different sizes is required, the operator pulls the pull frame 9. The pull frame 9 drives the sliding column 10 to slide within the assembly frame 2 and the hollow frame 8. At the same time, the sliding column 10 drives the positioning plate 5 to move inside the assembly frame 2 to accommodate the width of backlight films of different sizes. During the sliding of the sliding column 10, the sliding plate 12 on its outer wall slides on the inner wall of the hollow frame 8. The sliding plate 12 compresses the spring 11, causing the spring 11 to accumulate elastic potential energy. When the positioning plate 5 moves to the appropriate position, the pull frame 9 is released, the spring 11 releases its elastic force, and pushes the sliding plate 12 and the sliding column 10 to reset. This causes the positioning plate 5 to clamp and position the backlight film within the assembly frame 2. After the backlight film is positioned, the hydraulic cylinder 3 is activated, and its output end drives the pressure plate 20 to move downward to assemble the backlight film within the assembly frame 2. After assembly, the lifting assembly begins to work. The fixed frame 6, fixed inside the support frame 1, guides and supports the lifting column 16. When the electric push rod 7 is activated, its output end drives the inclined block 14 and the sliding frame 15 to slide on top of the fixed block 13. The inclined side of the inclined block 14 pushes the pulley 19. Since the pulley 19 is rotatably connected inside the notch frame 18, when the inclined block 14 pushes the pulley 19, the notch frame 18 drives the lifting column 16 to move upward. The lifting column 16 drives the lifting plate 4 to slide upward in the assembly frame 2, lifting the assembled backlight module. During the upward movement of the lifting column 16, the second spring 17 is stretched. When the electric push rod 7 is retracted, the second spring 17 releases its elasticity, pulling the notch frame 18 and the lifting column 16 downward to reset, so that the lifting plate 4 returns to its initial position, thereby achieving the purpose of lifting and unloading the assembled backlight module.
