Description

Technical Field

[0001] The invention belongs to the technical field of glass heating and forming, and relates to a liquid crystal display screen glass, in particular to a liquid crystal display screen glass heating and forming device. Background Art

[0002] Liquid crystal display is a type of flat panel display used for screen display of television and computer. The advantages of liquid crystal display are low power consumption, small size and low radiation, so liquid crystal display is widely used. Liquid crystal display generally includes two glass substrates with a thickness of 0.7mm-0.5mm. At present, the glass substrates used for LCD in China can be roughly divided into two categories: alkali glass and alkali-free glass.

[0003] In the entire glass substrate manufacturing process, the main technologies include feeding, sheet forming and post-processing. Among them, the feeding technology is mainly controlled by the quality of the formula. It not only needs to consider the various physical and chemical properties of the glass, but also needs to select the best formula of raw materials without changing the chemical composition, so as to effectively reduce the melting temperature of the glass, make the glass clear, and achieve specific glass properties to meet the needs of practical applications. The sheet forming technology is related to dimensional accuracy, surface properties and whether further processing and grinding are required to achieve special physical and chemical property requirements.

[0004] After searching, it is found that a Chinese patent document discloses a glass curved surface forming heating device [Application No.: CN201710617710.2; Publication No.: CN107298525A]. This forming heating device includes a controller and a heating cavity. A plurality of groups of heating coils are arranged in the heating cavity. Two adjacent groups of heating coils are arranged in a staggered manner. A mold lifting mechanism is provided below the heating coil. The mold lifting mechanism is installed in the heating cavity. The controller is electrically connected to the heating coil.

[0005] Although the glass curved surface molding heating device disclosed in this patent can lift multiple products into the heating coil for heating through the mold lifting mechanism, the heating coil is positioned in a single position, so that the heated molding surface of the glass is limited, which can easily lead to uneven heating of the glass substrate and affect the molding effect. In addition, lifting and heating multiple glasses by the lifting mechanism causes the glasses to overlap, resulting in unbalanced heating of the bottom and upper glasses, affecting the molding quality of the glass substrate. In addition, the open setting of the heating coil results in large heat loss, which increases the heating and molding cost of the glass during production and has poor practicality.

[0034] The working principle of the present invention is as follows: when in use, the glass material is fixed by setting the clamping frame 24 at the upper and lower ends, and the glass material is kept stable inside the clamping frame 24 under the action of the suction cup 33 connected inside the clamping frame 24, and the movable rod 25 is rotatably set above the clamping frame 24, and the second gear 26 is fixedly connected to one end of the movable rod 25. Through the meshing connection between the second gear 26 and the rack 17, the first gear 15 drives the clamping frame 24 to move the material inside the sleeve frame 16, so as to facilitate the loading of the material into the sleeve frame 16. At the same time, the first bevel gear 28 is fixedly connected to the outer wall of the movable rod 25, and the transmission rod 30 is driven to realize the transmission under the meshing action of the first bevel gear 28 and the second bevel gear 29. , so that the winding drums 31 on both sides of the clamping frame 24 drive the steel belt 32 to unwind, and under the action of the magnetic block 34 fixedly connected to the bottom end of the steel belt 32, the magnetic block 34 is adsorbed on the surface of the lower clamping frame 24, so that the steel belt 32 is limited on both sides of the glass material, avoiding deformation and sagging of the glass during the heat forming process, and ensuring the forming quality of the glass substrate. During the heating process, the first bevel gear 8 is driven by the bidirectional motor 6 to rotate on the surface of the bevel gear ring 9, so that the cover plate 4 drives the slider 5 to move on the outer wall of the baking oven 2, so that the cover plate 4 can close the through holes on both sides of the baking oven 2, so as to realize the efficient heating and forming of the glass substrate inside the baking oven 2. At the same time, in order to achieve the uniformity of the glass during forming. The driving motor 11 drives the rotating rod 10 to rotate. Under the action of the fixing rod 14 and the connecting plate 13, the rotating rod 10 drives the sleeve 16 to move through the connecting plate 13. The first gear 15 is fixedly connected to the upper part of the sleeve 16. Under the action of the first gear 15 meshing and connecting to the inner gear ring 19, the sleeve 16 is rotated below the connecting plate 13, thereby realizing the rotation and self-rotation of the glass inside the baking oven 2, which is convenient for the glass substrate to be uniformly heated and formed inside the baking oven 2. After the glass is formed, the through hole on one side of the guide component is opened by the first bevel gear 8, so that the cover plate 4 opens the through hole, and the sleeve 16 is driven to rotate to one side of the through hole by the rotating rod 10. The bidirectional motor 27 Under the rotation of , the second gear 26 rotates in the opposite direction, so that the winding drum 31 drives the steel belt 32 to reel up, thereby realizing the opening of both sides of the glass and avoiding the obstruction of both sides of the glass. Moreover, under the action of the second gear 26 fixedly connected to the outer end of the movable rod 25, the clamping frame 24 is extended inside the sleeve frame 16, so that the formed glass is moved between the two clamping plates 22. Under the action of the electric push rod 21, the clamping plates 22 clamp the glass on both sides, realizing the unloading of the glass substrate, and conveying the formed LCD glass through the conveying roller 23 at the bottom, realizing the integrated processing of the LCD glass, thus completing the working principle of the LCD glass heating and forming device.

[0035] In summary, by arranging a transmission rotation component inside the baking oven 2, the rotating rod 10 can drive the sleeve 16 to rotate inside the baking oven 2, so that the clamping frame 24 inside the sleeve 16 can drive the glass to be evenly heated and formed inside the baking oven 2, thereby avoiding the problem of uneven temperature of the glass heating and forming. In addition, by arranging cover plates 4 on both sides of the baking oven 2, the inside of the baking oven 2 can be stably loaded and unloaded, and the baking oven 2 is effectively closed, thereby avoiding heat loss of the glass during heating and reducing the cost of use. In addition, the glass substrate is driven to move stably by the clamping frame 24, thereby achieving stable loading and unloading of the glass inside the baking oven 2, thereby solving the problem that the current liquid crystal display glass substrate cannot be evenly heated and formed and heat loss cannot be reduced.
