[0013] Beneficial Effects

[0014] The present invention provides a flipping device for LCD display screen production, which has the following beneficial effects compared with the prior art:

[0015] 1. The user inserts the LCD screen into the gap between the two belts, and the gap between the two belts is equal to the thickness of the LCD screen. Then the user starts the motor connected by the gears. At this time, the two meshing gears start to rotate synchronously in the opposite direction, and drive the shaft cylinder fixedly connected to them to rotate synchronously. At this time, the two shaft cylinders start to cooperate with each other to drive the belts connected to them to start rotating. At this time, the two belts start to cooperate with each other to push the LCD screen between their gaps. At the same time, because the belts are sleeved with a soft anti-slip buffer layer, the limiting effect of the belts on the LCD screen can be effectively increased, and at the same time, it can provide a buffer for its contact to avoid damage to the LCD screen. During the transmission of the LCD screen, the user starts the motor synchronously. At this time, the transmission gear fixedly connected on the motor output shaft starts to rotate, and drives the gear ring meshing with it to start rotating. At this time, the two connecting sleeves start to rotate synchronously under the action of the shaft rod fixedly connected to them, and drive the connecting rod fixedly connected thereon to rotate synchronously. At this time, the LCD screen pushed forward between the two belts starts to rotate synchronously, and completes the flipping action after rotating °. When the LCD screen is flipped, it slides out from between the two belts and is on a longer belt for subsequent processing;

[0016] 2. When the user starts the motor and makes the two connecting sleeves rotate synchronously, the connecting rod drives the left-handed screw connected thereto to rotate synchronously, and makes the left-handed screw start to drive the sub-gear fixedly connected thereto to start rotating synchronously. At this time, the sub-gear starts to roll on it with the cooperation of the gear ring A meshing with it, so that the left-handed screw can realize self-rotation while revolving with it. At this time, the left-handed screw starts to drive the right-handed screw fixedly connected thereto to rotate synchronously, so that the left-handed screw and the slide cylinder threadedly connected on the right-handed screw start to move linearly along the connection with the connecting rod. At this time, the two slide cylinders start to move towards each other and drive the top rod hinged on them to slide synchronously. At this time, the top rod starts to push the push rod hinged with it The push plates on both sides of the belt start to move towards each other and approach the LCD screen until the rotating drum connected to the push plates starts to contact the screen, and the multiple rotating drums arranged on the push plates are used to guide the conveying of the screen. At the same time, the buffer rubber ring wrapped on the rotating drum can prevent it from causing indentations on both sides of the screen. At this time, the center positioning of the screen is completed to prevent the screen from falling to the ground along the gap at the connection due to the excessive weight of the screen during the flipping process. At the same time, the two push plates slide synchronously to push the screen to the middle of the belt to prevent it from leaving the predetermined position during the flipping process.

[0017] 3. During the rotation of the two belts, since the brush cylinder is provided with a damping rubber ring, the belt can synchronously pull multiple brush cylinders to rotate synchronously, so that the moistened brush cylinder can rotate and wipe the connection between it and the belt, and can wipe it as a whole through the circular rotation of the belt to remove dust and other impurities attached to the belt, thereby preventing the impurities on the belt from being coated on the display screen after the belt contacts the display screen, causing subsequent processing to be affected. At the same time, the user can synchronously start the motor A, so that the motor A drives the screw rod fixedly connected on its output shaft to rotate synchronously, and then starts to drive the slider threaded on it through the screw rod. At this time, the connecting frame fixedly connected to the slider starts to perform linear reciprocating motion along the limit rod, so that the connecting frame drives the multiple ring sleeves fixedly connected thereon to move synchronously, and the ring sleeves start to circulate and scrape the brush cylinder to remove dust and impurities generated after cleaning the belt, and when the connecting frame moves to both sides of the frame, the impurities on the ring sleeve can be pushed to the gap between the brush cylinder and the frame, thereby causing them to fall out of the device.

Then the user starts the motor connected to the gear 207. At this time, the two meshing gears 207 begin to rotate synchronously in opposite directions, and drive the shaft cylinder 205 fixedly connected thereto to rotate synchronously. At this time, the two shaft cylinders 205 begin to cooperate with each other to drive the belts 206 rotatably connected thereto to start rotating. At this time, the two belts 206 begin to cooperate with each other to push the LCD screen between their gaps. At the same time, since the belts 206 are provided with a soft anti-slip buffer layer, the limiting effect of the belts 206 on the LCD screen can be effectively increased, and at the same time, a buffer can be provided for their contact to avoid The LCD screen is damaged. During the transmission of the LCD screen, the user starts the motor 2001 synchronously.

At this time, the two connecting sleeves 201 start to rotate synchronously under the action of the shaft 202 fixedly connected thereto, and drive the connecting rod 203 fixedly connected thereto to rotate synchronously. At this time, the LCD screen that is pushed forward for transportation between the two belts 206 starts to rotate synchronously, and completes the flipping action after rotating 180°. When the LCD screen is flipped over, it slides out from between the two belts 206 and is on the longer belt 206 to facilitate subsequent processing.

[0032] Specifically, the anti-fall component 3 includes a slide rod 301, a slip ring 302 and a gear ring A303. The multiple slide rods 301 are symmetrically fixedly connected to the two connecting sleeves 201 respectively. The multiple slide rods 301 are slidingly connected to the slip ring 302 through the circular slide grooves on the slip ring 302. The two slip rings 302 are symmetrically fixedly connected on both sides of the base plate 101.

[0033] Specifically, the gear ring A303 is fixedly connected in the slip ring 302, and the gear ring A303 is symmetrically meshed with sub-gears 3001 on both sides.

[0034] Specifically, the left-handed screw rod 304 and the right-handed screw rod 305 are respectively threadedly connected with a slide cylinder 306, and the slide cylinder 306 is slidably connected to the connecting rod 203. The two slide cylinders 306 are respectively hinged with a push rod 307, and the other ends of the two push rods 307 are hinged on the push plate 308.

At this time, the sub-gear 3001 starts to roll on it with the cooperation of the gear ring A303 meshing with it, so that the left-handed screw rod 304 can realize self-rotation while revolving with it. At this time, the left-handed screw rod 304 starts to drive the right-handed screw rod 305 fixedly connected thereto to rotate synchronously, so that the left-handed screw rod 304 and the slide cylinder 306 threadedly connected on the right-handed screw rod 305 start to perform linear motion along the connection between them and the connecting rod 203. At this time, the two slide cylinders 306 start to move towards each other and drive the top rod 307 hinged on them to slide synchronously. At this time, The push rod 307 starts to push the push plate 308 hinged to it, so that the push plates 308 on both sides of the belt 206 start to move towards each other and start to approach the LCD screen until the rotating drum 309 rotatably connected to the push plate 308 starts to contact the screen, and the multiple rotating drums 309 rotatably arranged on the push plate 308 guide the transportation of the screen. At the same time, the buffer rubber ring wrapped on the rotating drum 309 can prevent it from causing pressure marks on both sides of the screen. At this time, the center positioning of the screen is completed to avoid the two belts 206 being unable to form an effective limit for the screen during the flipping of the screen due to the excessive weight of the screen, thereby causing the screen to fall to the ground along the gap at the connection, causing damage to the screen. At the same time, the two push plates 308 slide synchronously to push the screen to the middle of the belt 206 to prevent it from leaving the predetermined position during the flipping process.
