Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display manufacturing technology, and in particular to an automatic flipping device for liquid crystal display manufacturing. Background Technology

[0002] After the LCD screen is manufactured into a finished product, it still needs to undergo detailed testing, including performance and appearance testing. Appearance testing requires flipping the LCD screen to check for potential damage to various parts of the LCD screen. In order to save manpower and protect the LCD screen from damage during the flipping process, an automatic flipping device is usually used to automatically flip the LCD screen.

[0003] Currently, there are generally two types of automatic flipping devices used in LCD production. One type uses a clamping device to hold the LCD screen on the conveyor belt and lift it to a specified height. The clamping device then controls the LCD screen to flip 180 degrees before placing it back onto the conveyor belt. Because this method only clamps the two sides of the LCD screen, the flipping speed is relatively slow to ensure stability during the flipping process. The other type involves installing the clamping device between two conveyor belts. The clamping device holds the LCD screen from one conveyor belt and places it onto the other conveyor belt to complete the flipping operation. This method requires two conveyor belts during the flipping process, which occupies more space.

[0004] Therefore, in response to the above problems, an efficient automatic flipping device for LCD production has been developed that can control the LCD screen to flip rapidly in place. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art mentioned above, this utility model provides an automatic flipping device for LCD production that can control the LCD screen to flip rapidly in place with high efficiency.

[0006] The technical solution of this utility model is as follows: an automatic flipping device for LCD screen production, comprising a base plate, drive wheels, rotating frames, mounting frames, conveyor belts, movable rollers, clamping components, and stabilizing components. Drive wheels are symmetrically arranged on the upper sides of the left and right sides of the base plate. A mounting frame is arranged above the drive wheels. Rotating frames are connected to the front and rear sides of the mounting frame, and each rotating frame is in contact with an adjacent drive wheel. The drive wheels are used to drive the rotating frames to rotate. Conveyor belts are arranged on the upper and lower sides of the mounting frame, and movable rollers are rotatably connected to the upper and lower sides of the mounting frame. The conveyor belts are used to control the rotation of the movable rollers. A clamping component for clamping the LCD screen is provided on the mounting frame, and a stabilizing component for improving the stability of the LCD screen during flipping is provided on the clamping component.

[0007] To further explain, the clamping assembly includes a fixed frame, an electric push rod, a lifting frame, a mounting frame, and a clamping pad. The fixed frame is connected to the middle of the mounting frame, and the electric push rod is connected to both the upper and lower parts of the fixed frame. The lifting frame is connected to the telescopic end of the electric push rod, and multiple mounting frames are slidably connected to the lifting frame. Each mounting frame is connected to a clamping pad.

[0008] To further explain, the clamping assembly also includes springs, and the mounting brackets are all connected to the adjacent lifting brackets by springs.

[0009] To further clarify, the mounting brackets are arranged symmetrically from top to bottom.

[0010] To further explain, the stabilizing component includes a pneumatic actuator and a stabilizing block. Pneumatic actuators are connected to both the left and right sides of the mounting frame, and stabilizing blocks are installed on each pneumatic actuator. The stabilizing blocks are all located inside the mounting frame.

[0011] To further clarify, each stabilizer block is equipped with a protective pad.

[0012] The beneficial effects are as follows: This utility model uses an electric push rod to control the lifting frame, mounting frame and clamping pad to clamp and fix the LCD screen, and uses a pneumatic actuator to control the stabilizing block to clamp the side of the LCD screen. Then, the drive wheel drives the rotating frame to rotate the mounting frame, which can achieve the effect of controlling the LCD screen to rotate quickly in place with high efficiency.

Detailed Implementation

[0020] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] An automatic flipping device for LCD screen production, such as Figures 1-6 As shown, the device includes a base plate 1, drive wheels 2, rotating frame 3, mounting frame 4, conveyor belt 5, moving roller 6, clamping assembly, and stabilizing assembly. Drive wheels 2 are symmetrically arranged on the upper left and right sides of the base plate 1. The mounting frame 4 is positioned above the drive wheels 2. Rotating frames 3 are connected to both the front and rear sides of the mounting frame 4, and each rotating frame 3 contacts an adjacent drive wheel 2. The drive wheels 2 drive the rotating frames 3 to rotate. Conveyor belts 5 are installed on both the upper and lower parts of the mounting frame 4, and moving rollers 6 are rotatably connected to both the upper and lower parts of the mounting frame 4. The conveyor belts 5 control the rotation of the moving rollers 6. The mounting frame 4 is equipped with a clamping assembly for holding the LCD screen. The clamping assembly is equipped with a stabilizing assembly to improve the stability of the LCD screen during rotation. The rotating roller 6 is controlled by the conveyor belt 5, causing the LCD screen to move. After the LCD screen is completely conveyed into the mounting frame 4, it is clamped and fixed by the clamping assembly and the stabilizing assembly, thus improving its stability during rotation.

[0022] The clamping assembly includes a fixed frame 7, an electric push rod 8, a lifting frame 9, a mounting frame 10, and a clamping pad 11. The fixed frame 7 is connected to the middle of the mounting frame 4. The upper and lower parts of the fixed frame 7 are connected to the electric push rod 8. The lifting frame 9 is connected to the telescopic end of the electric push rod 8. Four mounting frames 10 are slidably connected to the lifting frame 9. The clamping pad 11 is connected to the mounting frame 10. The telescopic end of the electric push rod 8 drives the lifting frame 9 to move towards each other. The movement of the lifting frame 9 drives the mounting frame 10 and the clamping pad 11 to move towards each other until they contact the LCD screen. The upper and lower mounting frames 10 and the clamping pad 11 interact to clamp the LCD screen.

[0023] The clamping assembly also includes a spring 12. The mounting bracket 10 is connected to the adjacent lifting bracket 9 by a spring 12. The spring 12 is used for cushioning to prevent damage to the LCD screen during clamping.

[0024] The mounting bracket 10 is symmetrically arranged vertically to ensure the clamping stability of the clamping pad 11 on the LCD screen;

[0025] The stabilizing component includes a pneumatic actuator 13 and a stabilizing block 14. The left and right sides of the fixing frame 7 are connected to the pneumatic actuator 13, and the pneumatic actuator 13 is equipped with a stabilizing block 14. The stabilizing block 14 is located inside the mounting frame 4. The pneumatic actuator 13 drives the stabilizing block 14 to move towards each other, and the stabilizing block 14 clamps and fixes the LCD screen, thereby improving the stability of the LCD screen when it is flipped.

[0026] Each of the stabilizing blocks 14 is equipped with a protective pad.

[0027] In use, this invention first needs to be installed in the operating area. Then, the moving roller 6 is rotated by the conveyor belt 5, which moves the LCD screen. After the LCD screen is completely transported into the mounting frame 4, the lifting frame 9 is moved closer together by the telescopic end of the electric push rod 8. The movement of the lifting frame 9 moves the mounting frame 10 and the clamping pad 11 closer together until they contact the LCD screen. The upper and lower mounting frames 10 and the clamping pad 11 interact to clamp the LCD screen. During the clamping process, the applied pressure is buffered by the spring 12 to avoid damage to the LCD screen. Finally, the pneumatic actuator 13 drives the stabilizing mechanism. The fixed block 14 moves towards each other, clamping and fixing the side of the LCD screen through the stabilizing block 14. Then, the drive wheel 2 drives the rotating frame 3 to rotate the mounting frame 4 180 degrees, thereby causing the LCD screen to flip. After the flipping operation is completed, the pneumatic actuator 13 drives the stabilizing block 14 to move away from each other, so that it no longer clamps the side of the LCD screen. Then, the extension end of the electric push rod 8 drives the lifting frame 9 to move away from each other. The movement of the lifting frame 9 causes the mounting frame 10 and the clamping pad 11 to move away from each other and reset, so that the clamping pad 11 is away from the LCD screen. Finally, the conveyor belt 5 controls the rotation of the moving roller 6 to send the LCD screen out of the mounting frame 4.
