[0002] Liquid crystal display is a display technology widely used in electronic devices. Its basic principle is to use the optical properties of liquid crystal materials to display images. Liquid crystal display is usually composed of liquid crystal layer, glass substrate, polarizer, backlight, etc. Liquid crystal display transfer and conveying device is a device used to transfer the display from one process to the next process on the liquid crystal display production line.

[0003] The existing method of conveying LCD screens is to use a motor-driven conveyor belt to transport the display screen products along a specified path, and a fixed clamp is used to fix and maintain the position of the LCD screen during the conveying process. However, it does not have an automatic cleaning function and cannot clean the dust on the surface of the LCD screen, which is likely to affect the production quality of the LCD screen and affect the normal use of the LCD screen.

[0004] Therefore, it is necessary to design a liquid crystal display screen transfer and conveying device that can clean the dust on the surface of the liquid crystal display screen, improve the production quality of the liquid crystal display screen, and ensure the display effect and performance of the liquid crystal display screen. Utility Model Content

[0005] In order to overcome the shortcomings of the existing LCD screen transfer and conveying device that does not have the automatic cleaning function and is unable to clean the dust on the surface of the LCD screen, which easily affects the production quality of the LCD screen, the utility model provides a LCD screen transfer and conveying device that can clean the dust on the surface of the LCD screen, improve the quality of the LCD screen, and ensure the display effect and performance of the LCD screen.

[0006] The technical solution of the utility model is: a liquid crystal display screen transfer and conveying device, including a mounting frame, a motor, a rotating wheel, a conveyor belt, a flushing mechanism and a pressing mechanism, the rear side of the left portion of the mounting frame is connected with a motor, the left and right sides of the mounting frame are rotatably connected with rotating wheels, the left rotating wheel is connected to the motor output shaft, a conveyor belt is wound around the rotating wheels, the left portion of the mounting frame is provided with a flushing mechanism for making the liquid crystal display screen centered and flat, and the middle and right portions of the mounting frame are provided with three pressing mechanisms for cleaning dust on the surface of the liquid crystal display screen.

[0007] Optionally, the conveyor belt is made of rubber.

[0008] Optionally, support wheels are also included, and six support wheels are rotatably connected to the mounting frame to facilitate supporting the movement of the conveyor belt.

[0009] Optionally, the leveling mechanism includes a support plate, an electric push rod and a top plate. The left part of the mounting frame is connected to two front and rear support plates, each of which is connected to an electric push rod, and each of the telescopic ends of the electric push rod is connected to a top plate. The top plates are driven by the electric push rod to move inward at the same time, thereby making the LCD screen level and centered on the conveyor belt.

[0010] Optionally, the left portion of the top plate is inclined outwards to provide a guide.

[0011] Optionally, the pressing mechanism includes a support frame, a telescopic rod, a spring and a roller. Three support frames are connected to the middle and right parts of the mounting frame. Two front and rear telescopic rods are connected to the support frames. Springs are connected between the telescopic end and the fixed end of the telescopic rod. Rollers are rotatably connected between the telescopic ends of the telescopic rod. By stretching the telescopic rod downward, the spring is stretched, causing the roller to move downward and contact the LCD screen, thereby cleaning the dust on the surface of the LCD screen.

[0012] The utility model has the following advantages: 1. The utility model stretches the telescopic rod downward, the spring is stretched, so that the roller moves downward and contacts the LCD screen. When the LCD screen moves on the conveyor belt, the roller is driven to rotate, thereby cleaning the dust on the surface of the LCD screen, improving the production quality of the LCD screen, ensuring the display effect and performance of the LCD screen, and preventing dust from affecting the use of the LCD screen.

[0013] 2. The utility model drives the top plates on both sides to move inward and contact the LCD screen through the electric push rod, so that the LCD screen is flush and centered on the conveyor belt, thereby preventing the LCD screen from being damaged by collision or extrusion due to unevenness or position deviation during transportation, ensuring the quality of the LCD screen and reducing damage to the LCD screen.

DETAILED DESCRIPTION

[0018] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning.

[0019] LCD display transfer and conveying device, such as Figure 1-Figure 3 As shown, it includes a mounting frame 1, a motor 2, a rotating wheel 3, a conveyor belt 4, a leveling mechanism 6 and a pressing mechanism 7. The motor 2 is connected to the rear side of the left portion of the mounting frame 1, and the rotating wheels 3 are rotatably connected to the left and right sides of the mounting frame 1. The left rotating wheel 3 is connected to the output shaft of the motor 2, and a conveyor belt 4 is wound around the rotating wheels 3. The conveyor belt 4 is made of rubber and also includes supporting wheels 5. Six supporting wheels 5 are rotatably connected to the mounting frame 1. The left portion of the mounting frame 1 is provided with a leveling mechanism 6 for centering and leveling the liquid crystal display screen, and the middle and right portions of the mounting frame 1 are provided with three pressing mechanisms 7 for cleaning dust on the surface of the liquid crystal display screen.

[0020] like Figure 1-Figure 3 As shown, the leveling mechanism 6 includes a support plate 61, an electric push rod 62 and a top plate 63. The left part of the mounting frame 1 is connected to two front and rear support plates 61, each of which is connected to an electric push rod 62. The telescopic end of the electric push rod 62 is connected to a top plate 63, and the left part of the top plate 63 is inclined outward.

[0021] like Figure 1-Figure 3 As shown, the pressing mechanism 7 includes a support frame 71, a telescopic rod 72, a spring 73 and a roller 74. Three support frames 71 are connected to the middle and right parts of the mounting frame 1. The support frames 71 are each connected to two front and rear telescopic rods 72. A spring 73 is connected between the telescopic end and the fixed end of the telescopic rod 72. A roller 74 is rotatably connected between the telescopic ends of the telescopic rod 72.

[0022] When it is necessary to transfer the LCD screen, this device can be used to place the LCD screen on the conveyor belt 4, which is made of rubber. The motor 2 is started, and the rotating wheel 3 is driven by the motor 2 to rotate, thereby driving the conveyor belt 4 to rotate, so that the rotating wheel 3 on the right side also rotates, and the supporting wheel 5 on the mounting frame 1 is convenient for supporting the movement of the conveyor belt 4, thereby transporting the LCD screen on the conveyor belt 4, and then the electric push rods 62 on both sides are started at the same time, and the electric push rods 62 drive the top plates 63 on both sides to move inward and contact the LCD screen. The left part of the top plate 63 is tilted outward, which has a guiding effect, so that the LCD screen is flush and in the center of the conveyor belt 4, thereby preventing unevenness or position during transportation. The offset of the position causes the LCD screen to collide or be squeezed and cause damage, so as to ensure the quality of the LCD screen and reduce the damage of the LCD screen. After the LCD screen is flush, the telescopic rod 72 is stretched downward, and the spring 73 is stretched, so that the roller 74 moves downward and contacts the LCD screen. When the LCD screen moves on the conveyor belt 4, the roller 74 is driven to rotate, thereby cleaning the dust on the surface of the LCD screen, improving the production quality of the LCD screen, ensuring the display effect and performance of the LCD screen, and preventing dust from affecting the use of the LCD screen. After the cleaning is completed, the spring 73 rebounds, and the telescopic rod 72 contracts upward, thereby driving the roller 74 to move upward and reset. After the conveying is completed, the motor 2 and the electric push rod 62 can be turned off.
