Description

Technical Field

[0001] This utility model relates to the field of display screen manufacturing technology, specifically a drying device for the production of liquid crystal displays. Background Technology

[0002] In the manufacturing process of LCD screens, the drying process is a crucial step. LCD screens have extremely high requirements for the humidity of the production environment and the dryness of internal components. If drying is not thorough, residual moisture may cause problems such as abnormal alignment of liquid crystal molecules and electrode oxidation, which will seriously affect the display effect, lifespan, and overall quality of the screen, and may even cause the product to be scrapped, resulting in huge economic losses for the manufacturing company.

[0003] Traditional LCD screen drying methods mostly employ static drying, where the LCD screens to be dried are placed in a fixed drying chamber and dried by hot air circulation. However, this static drying method has several drawbacks. Firstly, because the LCD screens are fixed in position within the drying chamber, the heating of different parts of the screen may be uneven. Areas closer to the heat source dry too quickly, while areas farther away dry more slowly, resulting in inconsistent overall drying effects and affecting product quality stability. Therefore, a drying device for LCD screen production is proposed to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drying device for LCD screen production, which has the advantages of uniform drying of the screen and high product quality stability, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for the production of liquid crystal displays, comprising a drying chamber body, a movable door hinged to one end of the drying chamber body, a dryer body fixedly connected inside the drying chamber body, and a transmission mechanism and a limiting mechanism provided inside the drying chamber body.

[0006] Furthermore, the transmission mechanism includes a frame fixedly connected inside the drying chamber body, a motor fixedly connected to one end of the frame, a movable wheel provided on the top of the frame, a rotating frame rotatably connected to the top of the frame through the movable wheel, a gear fixedly connected to the outer surface of the motor output shaft, and a gear ring fixedly connected to the outer surface of the rotating frame.

[0007] Furthermore, the limiting mechanism includes a fixed frame fixedly connected inside the rotating frame, an electric push rod fixedly connected to one end of the fixed frame, a connecting piece fixedly connected to the bottom of the electric push rod, a limiting rod fixedly connected inside the fixed frame, a fixed clamping plate fixedly connected to the outer surface of the limiting rod, a movable clamping plate slidably connected to the outer surface of the limiting rod, and a connecting rod fixedly connected to the outer surface of the movable clamping plate.

[0008] Furthermore, the dryer body is located at the bottom of the rotating frame.

[0009] Furthermore, the rotating frame is movably connected to the movable wheel through a groove on its outer surface, and the gear meshes with the gear ring.

[0010] Furthermore, the movable clamping plate is fixedly connected to the electric push rod via a connector, and both the movable clamping plate and the fixed clamping plate are provided with anti-slip pads on their outer surfaces.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] 1. This drying device for LCD screen production uses a transmission mechanism to drive a gear through a motor, which in turn drives a gear ring meshing with the gear to rotate a rotating frame. The LCD screen is fixed on the rotating frame and its position and angle change continuously as the frame rotates, allowing the screen to receive hot air drying from all directions and evenly during the drying process. This avoids the problem of uneven heating in traditional static drying methods, greatly improves drying quality, ensures that all parts of the LCD screen are fully dried, and effectively reduces display defects and quality problems caused by uneven drying.

[0013] 2. The drying device used for LCD screen production features an electric push rod design in its limiting mechanism, which makes it more convenient and faster to place and fix the LCD screen. By simply controlling the extension and retraction of the electric push rod, the movable clamping plate can be driven to slide along the limiting rod, realizing automatic clamping and loosening of the LCD screen. There is no need for manual adjustment of the clamps, which greatly reduces manual operation, reduces labor intensity, and improves the degree of production automation. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-4 This embodiment of a drying device for LCD screen production includes a drying chamber body 1, a movable door 101 hinged to one end of the drying chamber body 1, a dryer body 2 fixedly connected inside the drying chamber body 1, and a transmission mechanism 3 and a limiting mechanism 4 provided inside the drying chamber body 1.

[0021] The transmission mechanism 3 includes a frame 301 fixedly connected inside the drying chamber body 1. A motor 302 is fixedly connected to one end of the frame 301. A movable wheel 304 is provided on the top of the frame 301. A rotating frame 305 is rotatably connected to the top of the frame 301 via the movable wheel 304. The dryer body 2 is located at the bottom of the rotating frame 305. The rotating frame 305 is movably connected to the movable wheel 304 through a groove provided on its outer surface, which can make the rotating frame 305 more stable when rotating. A gear 303 is fixedly connected to the outer surface of the output shaft of the motor 302, and a gear ring 306 is fixedly connected to the outer surface of the rotating frame 305. The gear 303 meshes with the gear ring 306.

[0022] By setting up a transmission mechanism 3, the motor 302 drives the gear 303 to rotate, which in turn drives the gear ring 306 meshing with the gear 303 to rotate the rotating frame 305. The LCD screen is fixed on the rotating frame 305, and its position and angle change continuously as the rotating frame 305 rotates, so that the screen can receive hot air drying in all directions and evenly during the drying process. This avoids the problem of uneven heating in the traditional static drying method, greatly improves the drying quality, ensures that all parts inside the LCD screen are fully dried, and effectively reduces display defects and quality problems caused by uneven drying.

[0023] Secondly, the limiting mechanism 4 includes a fixed frame 401 fixedly connected inside the rotating frame 305. An electric push rod 402 is fixedly connected to one end of the fixed frame 401, and a connector 407 is fixedly connected to the bottom of the electric push rod 402. A limiting rod 404 is fixedly connected inside the fixed frame 401, and a fixed clamping plate 403 is fixedly connected to the outer surface of the limiting rod 404. A movable clamping plate 405 is slidably connected to the outer surface of the limiting rod 404, and a connecting rod 406 is fixedly connected to the outer surface of the movable clamping plate 405. The movable clamping plate 405 is fixedly connected to the electric push rod 402 via the connector 407, which connects the movable clamping plates 405 to each other. The specific number of movable clamping plates 405 can be set according to actual usage requirements. Anti-slip pads are provided on the outer surfaces of both the movable clamping plate 405 and the fixed clamping plate 403 to minimize the possibility of the display screen becoming loose. If the display screen clamping area is not thoroughly dried, it can be precisely dried separately. This technical solution solves the problem of uniform drying.

[0024] In this technical solution, both the electric actuator and the motor are designed to be high-temperature resistant. Specific options include the following:

[0025] Electric linear actuators: Linak LA36 or Thomson EL20 are preferred;

[0026] Motor: SEW MOVITRAC® B (large equipment) or Siemens 1LE0001 (small and medium-sized equipment), servo motors are used for high-precision applications.

[0027] The working principle of the above embodiments is as follows:

[0028] (1) The drying device for LCD screen production is provided with a transmission mechanism 3. The motor 302 drives the gear 303 to rotate, which in turn drives the gear ring 306 meshing with the gear 303 to rotate the rotating frame 305. The LCD screen is fixed on the rotating frame 305. As the rotating frame 305 rotates, the position and angle change continuously, so that the screen can be dried by hot air in all directions and evenly during the drying process. This avoids the problem of uneven heating in the traditional static drying method, greatly improves the drying quality, ensures that all parts inside the LCD screen can be fully dried, and effectively reduces display defects and quality problems caused by uneven drying.

[0029] (2) The electric push rod 402 in the limiting mechanism 4 of the drying device used for LCD screen production makes it more convenient and faster to place and fix the LCD screen. By controlling the extension and retraction of the electric push rod 402, the movable clamping plate 405 can be driven to slide along the limiting rod 404 to realize the automatic clamping and release of the LCD screen. There is no need for manual adjustment of the clamps, which greatly reduces the manual operation links, reduces labor intensity, and improves the degree of production automation.
