Abstract
Description
Technical Field

The device includes a main frame, an adjusting block on the left side of the main frame, and an adjusting mechanism inside the main frame, comprising an adjusting section. This edge-sealing device for processing MINI LED backlight modules utilizes a worm gear, a worm, a screw, and a third sliding rod. Rotating the worm drives the worm gear and screw to rotate, and the screw moves the adjusting block left and right, allowing for fine-tuning of the distance between the adjusting block and the main frame. This enables the device to process backlight modules of different sizes.
[0004] However, the T-shaped slide in this utility model lacks self-lubricating function, and cannot perform lubrication in a timely manner during use, resulting in direct dry friction between the slider and the metal surface of the T-shaped groove. During sliding, it is necessary to overcome a large static friction force, which seriously affects the adjustment quality and thus cannot meet production requirements. Therefore, an edge sealing device for LED backlight module processing is proposed to solve the above-mentioned problems. 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 Figures 1 to 4 This embodiment discloses an edge-sealing device for processing LED backlight modules, comprising a first frame 1 and a second frame 2. An adjusting screw 3 is installed between the first frame 1 and the second frame 2, wherein the adjusting screw 3 is threadedly connected to the inside of the second frame 2. A knob fixed to the end of the adjusting screw 3 is rotatably installed on one side of the first frame 1. A platform 4 is provided on the second frame 2, and a hydraulic device is provided above the platform 4. A guide rail 10 is installed between the platform 4 and the second frame 2. Specifically, the hydraulic device includes a hydraulic telescopic rod 6 fixed to the top side of the second frame 2, the hydraulic telescopic rod 6 penetrating the inside of the second frame 2, and an abutment plate 7 is installed on the output end of the hydraulic telescopic rod 6. A pressure plate 5 is provided below the abutment plate 7 and is located above the platform 4. When the hydraulic telescopic rod 6 drives the abutment plate 7 and the pressure plate 5 to press down, the guide rod 8 cooperates with the return spring 9 to provide a certain buffer space after the pressure plate 5 contacts the module, so as to avoid rigid pressure damaging the backlight module, while ensuring uniform pressure distribution and improving the sealing fit and consistency.
[0024] The pressure plate 5 has a guide rod 8 fixed to its upper surface, penetrating the interior of the abutment plate 7. A return spring 9 is installed between the outer surface of the guide rod 8 and the top side of the abutment plate 7. The outer surface of the guide rod 8 is also equipped with scale lines, which visually display the displacement of the pressure plate 5 relative to the abutment plate 7. By observing the scale changes, operators can precisely control the pressing depth of the pressure plate 5, avoiding damage to the backlight module due to excessive pressure or inadequate sealing due to insufficient pressure, thereby improving the sealing fit and consistency.
[0025] A lubrication structure for lubricating the guide rail 10 is provided below the platform 4. The lubrication structure includes a plug cylinder 11 fixed to the lower surface of the platform 4. A piston 14 is slidably disposed inside the plug cylinder 11. A reciprocating rod 12 extending to the outside of the plug cylinder 11 is fixed to one side of the piston 14. A ball bearing 15 is rotatably mounted at the bottom end of the reciprocating rod 12. A check valve 13 is installed on the side wall of the piston 14. An infusion tube 17 is installed at the end of the check valve 13. A guide seat 20 for use with the ball bearing 15 is installed inside the second frame 2. Specifically, an installation groove 19 is opened inside the second frame 2. The guide seat 20 is fixed inside the installation groove 19. The guide seat 20 has a wavy shape. The wavy design of the guide seat 20 causes the ball bearing 15 to move up and down periodically during the movement of the platform 4, driving the piston 14 to intermittently squeeze the lubricant in the plug cylinder 11. A guide frame 21 for limiting the movement of the platform 4 is installed on the outer surface of the second frame 2.
[0026] The guide rail 10 consists of a track and a slider. The track is fixed to the outer surface of the second frame 2, and the slider is fixed to the lower surface of the platform 4. A lubricating pad 18 is detachably installed on the outer surface of the slider. The lubricating pad 18 on the slider surface is designed to be detachable. When the lubricating pad 18 is worn or clogged, it is not necessary to replace the entire guide rail 10 or the slider; only the lubricating pad 18 needs to be replaced to restore the lubrication function, significantly reducing maintenance costs and time. A sliding opening is provided on the side wall of the track, and the infusion tube 17 passes through the sliding opening and is fixedly connected to the lubricating pad 18. A buffer spring 16 is installed between the outer surface of the reciprocating rod 12 and the bottom side of the plug cylinder 11. A liquid storage box is installed on the bottom side of the platform 4. There are two infusion tubes 17 and two check valves 13, one of which is fixedly connected to the liquid storage box. By continuously lubricating the friction surface of the guide rail 10, wear between the slider and the track is reduced, and deviations in the movement of the platform 4 caused by jamming or decreased accuracy of the guide rail 10 are avoided, thereby ensuring the positioning accuracy of the module during edge sealing and improving product quality.
[0027] The working principle of the above embodiments is as follows:
[0028] When the hydraulic telescopic rod 6 drives the abutment plate 7 and the pressure plate 5 to press down, the guide rod 8 cooperates with the return spring 9 to provide a certain buffer space after the pressure plate 5 contacts the module, so as to avoid rigid pressure damaging the backlight module, while ensuring uniform pressure distribution and improving the sealing fit and consistency.
[0029] When the platform 4 moves, the ball bearing 15 at the bottom of the reciprocating rod 12 rolls along the wave-shaped guide seat 20, driving the piston 14 to reciprocate in the plug cylinder 11. The check valve 13 controls the unidirectional flow of lubricating fluid, and the lubricating fluid is accurately delivered to the lubrication pad 18 of the guide rail 10 through the infusion pipe 17, realizing automatic lubrication during the movement process without manual intervention, extending the life of the guide rail 10 and reducing downtime maintenance time.
[0030] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.
[0031] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
