Description

Technical Field

[0001] This utility model relates to the field of backlight module processing technology, specifically to a backlight module adhesive coating device. Background Technology

[0002] The backlight module, also known as the backlight source, is one of the key components of an LCD display. Its function is to provide sufficient brightness and a uniformly distributed light source so that the LCD panel can display images normally. The basic structure of the backlight module includes components such as the light source, light guide plate, frame, reflector, diffuser, and brightness enhancement film. The backlight module is a light source located behind the LCD display, and its light emission effect directly affects the visual effect of the LCD module. The liquid crystal itself does not emit light; it displays graphics or characters as a result of its modulation of light.

[0003] With increasing market competition and changing consumer demands, backlight module manufacturers need to continuously launch new products and technologies to meet market needs. As a crucial piece of equipment in the backlight module production process, the performance and quality of the coating device directly impact the market competitiveness of the backlight module. Therefore, a backlight module coating device is needed to coat the backlight module with adhesive. Existing backlight module coating devices require storing the adhesive in a storage tank before coating. During prolonged use, excessively long storage time can cause the adhesive components to frost, separate, or prematurely solidify, affecting the coating quality. Furthermore, in existing backlight module coating devices, the adhesive typically falls from the outlet due to gravity. However, these devices often lack a structure at the outlet, resulting in inconsistent adhesive output. This leads to uneven coating and difficulty in controlling the amount of adhesive applied, ultimately affecting the performance of the backlight module. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5As shown, a backlight module adhesive coating device includes a worktable 1. Two sets of support plates 2 are fixed to the top of the worktable 1. A longitudinally arranged storage hopper 3 is fixed to the top of the support plates 2. A sealing cover 4 is rotatably connected to the top of the storage hopper 3. The two sets of support plates 2 can support the storage hopper 3 on its top. The storage hopper 3 can store adhesive. The sealing cover 4 can seal the storage hopper 3, thereby preventing the adhesive from splashing during the mixing process. A first motor 5 is arranged on the outside of the storage hopper 3, and the output end of the first motor 5 penetrates through the inner wall of the storage hopper 3 into its interior. A stirring roller 6 is rotatably connected inside the storage hopper 3. Furthermore, one end of the stirring roller 6 is fixedly connected to the output end of the first motor 5. By setting the first motor 5, it is easy to drive the stirring roller 6 to rotate. The stirring roller 6 stirs the glue inside the storage hopper 3, preventing the glue from solidifying after the storage hopper 3 has been standing for a long time. The bottom of the storage hopper 3 is provided with a screening mechanism 7. By setting the screening mechanism 7, it is easy to screen the glue, so that the glue can be evenly distributed on the backlight module. The inner walls of the two sets of support plates 2 are provided with vertically set grooves 8. The inside of the grooves 8 is provided with scraping mechanisms 9. By setting the grooves 8, it is easy to limit the scraping mechanisms 9 set on their inner walls.

[0024] The screening mechanism 7 includes a fixed frame 71 fixed to the inner wall of the storage hopper 3, and the fixed frame 71 surrounds the discharge port of the storage hopper 3. A screen plate 72 is provided on the top of the fixed frame 71, and the screen plate 72 fits into the discharge port of the storage hopper 3. A limit frame 73 is fixed to the bottom of the storage hopper 3, and a baffle 74 is slidably connected to the inner wall of the limit frame 73. The fixed frame 71 on the inner wall of the storage hopper 3 can easily support the screen plate 72 on top. The screen plate 72 can easily screen the glue inside the storage hopper 3, so that the glue can fall evenly from the discharge port at the bottom of the storage hopper 3. The limit frame 73 can easily limit the sliding baffle 74 on its inner wall. The baffle 74 can easily block the glue from the discharge port. At the same time, a push rod is fixed on one side of the baffle 74, so that the baffle 74 can be removed to allow the glue to fall.

[0025] The scraping mechanism 9 includes a bracket 91 fixed to the top of the support plate 2. A vertically installed threaded rod 92 is rotatably connected to the inner wall of the bracket 91. A horizontally installed scraper 93 is rotatably connected to the bottom end of the threaded rod 92. Both ends of the scraper 93 are fixed with sliders that are slidably connected to the inner wall of the slide groove 8. A slide rod 94 is fixed to the inner wall of the slide groove 8, and the outer side of the slide rod 94 is slidably connected to the inner wall of the sliders fixed to both ends of the scraper 93. The bracket 91 supports the threaded rod 92 installed on its inner wall. A fixing bolt for fixing the threaded rod 92 is provided on one side of the bracket 91. The rod 92 is designed to rotate with the bracket 91 via a thread, thereby moving the scraper 93. This allows the device to adjust the position of the scraper 93 according to different sizes of backlight modules. A turntable is fixed to the top of the threaded rod 92 to drive its rotation. Additionally, a set of scrapers 93 is fixed to the inner wall of the support plate 2. The two sets of scrapers 93 are symmetrically designed. The scrapers 93 can scrape off excess glue on the backlight module, thereby ensuring that the glue on the backlight module is evenly distributed. By setting a slide bar 94, the scraper 93 that slides on the outside of the slider can be easily limited.

[0026] The inner wall of the support plate 2 is rotatably connected to a first limiting roller 10 and a second limiting roller 11, which are symmetrically designed vertically. The symmetrically arranged first limiting roller 10 and second limiting roller 11 can limit the backlight module. A second motor 12 is provided on one side of the support plate 2, and the output end of the second motor 12 passes through the inner wall of the support plate 2 to the other side. The inner wall of the support plate 2 is rotatably connected to a first coating roller 13 and a second coating roller 14, which are symmetrically designed vertically. One end of the first coating roller 13 is fixedly connected to the output end of the second motor 12. By setting the second motor 12, it is easy to drive the first coating roller 13 fixed at its output end to rotate. At the same time, the first coating roller 13 can cooperate with the second coating roller 14 below to apply glue to the backlight module.

[0027] The inner wall of the workbench 1 has an inner cavity 15, and a storage box 16 is installed inside the inner cavity 15. A pull rod 17 is fixed to one side of the storage box 16. A limiting block 18 is fixed inside the inner cavity 15, and the inner wall of the limiting block 18 fits with the outer side of the storage box 16. The opening of the inner cavity 15 allows the storage box 16 to be placed, so that excess glue can fall into the storage box 16 by gravity. By setting up the storage box 16, it is convenient to store excess glue. By setting up the pull rod 17, it is convenient to take out the storage box 16, so that the excess glue can be reused. The fit design between the inner wall of the limiting block 18 and the outer side of the storage box 16 can be used to limit the storage box 16, so that the storage box 16 can be placed under the coating structure to prevent the storage box 16 from shifting during placement.

[0028] Working principle: In use, firstly, the glue is poured into the storage hopper 3, then the first motor 5 is started. The first motor 5 drives the stirring roller 6 to stir the glue in the storage hopper 3 to prevent the glue from solidifying. Then, according to the backlight module to be coated, it passes through the first limiting roller 10 and the second limiting roller 11. When the backlight module moves below the storage hopper 3, the push rod is pulled to pull out the baffle 74. The glue will pass through the screen plate 72 by gravity and fall evenly from the outlet onto the first coating roller 13. Then, the second motor 12 is started, which drives the first coating roller 13 to rotate. 13 is used in conjunction with the second coating roller 14 to apply adhesive to the backlight module. Then, according to the size of the backlight module, the turntable at the top of the threaded rod 92 is rotated. The turntable drives the threaded rod 92 to rotate. The threaded rod 92 can move up and down by rotating with the support 91, which can drive the scraper 93 to move. After the scraper 93 is moved to the appropriate position, the scraper 93 can scrape off the excess adhesive on the backlight module, so that the adhesive on the backlight module can be evenly distributed. The excess adhesive will fall into the storage box 16 below by gravity. Finally, the backlight module is pulled out to complete the purpose of applying adhesive to it.
