[0002] Multimedia devices are devices that can provide many multimedia functions, including computers, televisions, scanners, projectors, printers, etc. These multimedia devices often require the use of liquid crystal displays, or LCDs. The structure of LCD is to place a liquid crystal box between two parallel glass substrates, with TFTs (thin film transistors) set on the lower substrate glass and color filters set on the upper substrate glass.

[0020] An LCD automatic patch production method comprises the following steps:

[0021] S1. First, place the substrate in the placement box, start the electric push rod to drive the lifting frame upward, and push the substrate into the lifting frame, start the electric push rod to reset and drive the lifting frame to move downward, so that the substrate is immersed in the cleaning box;

[0022] S2. Then, the electric push rod can drive the stirring blade and the rotating block to stir the cleaning liquid in the cleaning box while resetting, so that the cleaning liquid in the cleaning box flows and cleans the substrate;

[0023] S3, then start the electric push rod to drive the lifting frame to move upward, and drive the substrate in the placement box to move into the lifting frame, and push the substrate in the lifting frame onto the conveyor;

[0024] S4. Finally, during the pushing process, the piston rod is driven to move to spray the cleaning liquid in the piston cylinder onto the substrate for further washing.

[0025] In the present application, first, the top plate is pushed downward to move until the second guide rod contacts the ground, the substrate is placed on the top plate, the top plate is released, and the top plate can move upward under the action of the first spring, driving the top substrate to contact the top inner wall of the placement box, and the electric push rod is started to drive the push plate to move. During the movement of the push plate, the first rack can be driven to move. The movement of the first rack drives the nut ring to rotate through the first gear, driving the lifting frame to move upward, and the electric push rod is continued to be started to drive the push plate to move. The substrate can be driven to move through the first resistance block to push the substrate into the lifting frame. At this time, the first resistance block is located on the top of the second substrate, and then the electric push rod is started to reset to drive the lifting frame to move downward, so that the substrate is immersed in the cleaning box;

[0026] Then, the electric push rod can drive the push plate to reset and move while resetting, and can drive the extension frame to move. The extension frame can drive the second rack to move through the extension rod. The movement of the second rack can drive the second gear to rotate, and drive the first rotating shaft to rotate. During the rotation of the first rotating shaft, the stirring shaft can drive the stirring blade to stir the cleaning liquid and drive the arc block to rotate. The rotation of the arc block can drive the rotating block to rotate on the second rotating shaft. When the arc block is away from the rotating block, the rotating block can be reset under the action of the torsion spring, so that the rotating block contacts the side of the limit block, which can further stir the cleaning liquid, agitate the cleaning liquid, clean the substrate in the lifting frame, drive the stirring blade and the rotating block to stir the cleaning liquid in the cleaning box, make the cleaning liquid in the cleaning box flow, and clean the substrate;

[0027] Then the electric push rod is started to drive the lifting frame to move upward, and the substrate in the placement box is driven to move into the lifting frame, and the substrate in the lifting frame is pushed onto the conveyor;

[0028] At the same time, during the pushing process, the push plate can drive the piston rod to move, and the movement of the piston rod can squeeze out the cleaning liquid in the piston cylinder and spray it on the substrate through the water spray pipe to further rinse the substrate, so that it can rinse while moving;

[0029] At the same time, the extension frame can push the baffle to move during the movement, and can drive the conveyor belt to move to transport the substrate. When the extension frame is reset, it can drive the stopper to move upward through the subsequent baffle until the stopper moves to the other side of the baffle. At this time, the stopper can be reset under the action of the second spring.

[0030] In the present invention, the LCD automatic patch production line can not only push the substrate into the lifting frame through the setting of the feeding mechanism, but also drive the lifting frame to rise and fall, so that the substrate is immersed in the cleaning box, so that it can avoid the collision caused by manual movement and improve the cleaning efficiency;

[0031] In the present invention, the automatic LCD patch production line can not only clean the substrate through the setting of the cleaning mechanism and the flushing mechanism, but also flush it after cleaning, thereby improving the cleaning effect, and is used in conjunction with the feeding mechanism without the need for an additional power source, thereby reducing the production cost;

[0032] In the present invention, the automatic LCD patch production line can drive the conveyor belt to move through the cooperation of the feeding mechanism and the baffle, so that the substrate can be continuously conveyed, and the substrates can be isolated from each other by the baffle during the conveying process to avoid collision during the conveying process;

[0033] In the present invention, by starting the electric push rod, not only can the push plate be driven to move to transport the substrate, but also the lifting frame can be driven to rise and fall, so that the substrate is immersed in the cleaning liquid in the cleaning box, and the stirring blade and the rotating block can be driven to rotate to clean the substrate, and the substrate can be rinsed after cleaning, thereby improving the cleaning efficiency and cleaning effect, and can also reduce the production cost and is easy to use.

[0062] The inner wall of the cleaning box 2 is fixed with two symmetrically arranged second rotating shafts 37, the outer wall of the second rotating shaft 37 is rotatably sleeved with a rotating block 38, the outer wall of the second rotating shaft 37 is sleeved with a torsion spring 39 located in the rotating block 38, the two ends of the torsion spring 39 are respectively fixedly connected to the outer wall of the second rotating shaft 37 and the inner wall of the rotating block 38, a limit block 40 used in conjunction with the rotating block 38 is fixedly provided on the inner wall of one side of the cleaning box 2, and the outer wall of the stirring shaft 34 is fixedly sleeved with an arc block 36 used in conjunction with the two rotating blocks 38. When the stirring shaft 34 rotates, the arc block 36 will be driven to rotate. When the arc block 36 contacts the rotating block 38, the rotating block 38 will be driven to rotate on the second rotating shaft 37. When the arc block 36 is away from the rotating block 38, the rotating block 38 can be reset under the force of the second rotating shaft 37, which can further stir the cleaning liquid, and the arc block 36 is located below the second rotating shaft 37 to avoid the arc block 36 from colliding with the rotating block 38 when it rotates.

[0063] A stopper 42 used in conjunction with the baffle 15 is provided through the top of the extension frame 14, and a third guide rod 43 is fixedly provided on the top of the extension frame 14.

When the push plate 10 moves, the stopper 42 can be driven to move by the extension frame 14. The movement of the stopper 42 can push the baffle 15 to drive the conveyor belt to move to transport the substrate. When the push plate 10 drives the stopper 42 to reset, the subsequent baffle 15 can drive the stopper 42 to move upward until the stopper 42 is away from the baffle 15. At this time, the stopper 42 can be reset downward under the action of the second spring 44 and move to the other side of the baffle 15, which is convenient for pushing the baffle 15 to move again.

[0064] A one-way valve 18 is provided on the connecting pipe 17 and the pipeline. Through the setting of the one-way valve 18, when the piston rod 20 is extended, the cleaning liquid in the piston cylinder 6 can be squeezed into the water spray pipe 24 through the pipeline, and will not flow into the clean water tank 5 through the connecting pipe 17. When the piston rod 20 is reset and moved, the cleaning liquid in the clean water tank 5 can be drawn into the piston cylinder 6, and the air in the pipeline will not flow into the piston cylinder 6, thereby improving the flow efficiency of the cleaning liquid.

[0065] However, as is well known to those skilled in the art, the working principle and wiring method of the electric push rod 11 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selection according to their needs or convenience.
