Description

Material mixing and preheating device for manufacturing glass substrates of next-generation display panels

The present invention relates to a material mixing and preheating apparatus for manufacturing a glass substrate of a next-generation display panel, and more particularly, in the manufacturing process of a glass substrate constituting a next-generation display panel, the raw material of the glass substrate is input, and the input material is uniformly distributed It relates to a material mixing and preheating apparatus for manufacturing a glass substrate of a next-generation display panel that improves productivity by reducing the time required for melting by mixing to have a high level of mixing and at the same time preheating before melting the raw material and transferring it to the melting furnace.

A liquid crystal display (LCD) is formed by interposing a liquid crystal between two glass substrates and implements a display by applying a voltage. There is this.

An organic light-emitting diode (OLED) is a technology used as a more advanced next-generation display from such a liquid crystal display device. It has the advantage of being light in weight and having the same size as it is relatively light, and has high power efficiency and excellent contrast ratio.

On the other hand, there is a disadvantage called burn-in phenomenon, which occurs when the same color is exposed for a long time because the lifespan of the light emitting device is short, which inevitably deteriorates the organic material used in the device over time, and also a material that is weak to heat because it wins Recently, the burn-in phenomenon in red and green among RGB (red, green, blue) has been greatly reduced, but there is a problem that burn-in occurs relatively frequently in the case of blue.

Next-generation displays to replace the organic light emitting diode include mini LED and micro LED, which are self-luminous displays in which micro LED elements emit light by themselves and act as pixels, respectively, and have bright and clear image quality and wide viewing angles. In addition, it has the advantage of being able to expand the size of the panel indefinitely because it can be configured in a way of connecting with a bezel-less design without a border.

However, since mini LED and micro LED are currently in the stage of technology development, many steps and time are still needed before commercialization.

On the other hand, the display panel is configured to include a glass substrate. For example, a TFT-LCD panel requires two glass substrates used as a bottom glass substrate and a bottom plate of a color filter, and the glass substrate used here is alkali glass. and alkali-free glass.

Alkali glass includes two kinds of sodium glass and neutral silicate glass used in TN and STN LCD, alkali free glass is based on Alumino Silicate Glass glass (SiO2, AI2O3, B2O3 and BaO), and the total alkali metal content is 1 % and is mainly used for TFT-LCD.

The properties of ultra-thin flat glass substrates mainly depend on the composition of the glass, and the composition of the glass depends on the thermal expansion, viscosity (strain, heat treatment, strain softening and action point), chemical resistance, optical penetration at various frequencies and temperatures, and electrical properties. The quality of the product is determined by the composition of the material and the production process.

Here, the characteristics of the glass substrate applied to the display panel include surface characteristics, heat resistance, resistance characteristics and alkali metal content, and the main physical properties of the glass substrate used for TFT-LCD include tensile point, special gravity, and coefficient of thermal expansion.

The strain point is an indicator of glass molding, which is a property that withstands high temperatures in the production process of LCD products. It is to determine the rate of expansion or contraction of the material, and the lower the coefficient, the lower the thermal expansion and cold water shrinkage of a large screen.

In addition to the above physical properties, melting point, softening point, chemical resistance, mechanical strength, optical properties and electrical properties may be included, and the properties and properties may be adjusted according to the needs of the purchaser purchasing the final product.

The manufacturing method of such a glass substrate is largely divided into a floating method, a flow hole down method, and an overflow melting method, and each method is determined according to the use used and the required characteristics.

The moving clip 53 is movably disposed at one end in the longitudinal direction of the rod 51 , and one end of the wire 514 disposed in the operation hole 513 of the rod 51 is coupled thereto.

Here, the moving clip 53 moves in conjunction when the wire 514 moves by the operation of the manipulation handle 55 to be described later, and a return means 56 for returning the moved moving clip 53 to its original position. provided

The return means 56 includes a pair of locking projections 561 formed in an annular shape in the operation hole 513 of the rod 51 and spaced apart from each other in the longitudinal direction of the rod, and the rod 51 . ) is formed and is disposed between the moving slot 562 for communicating the operation hole 513 and the outside, and the pair of locking jaws 561, and is coupled to the moving clip 53 in the moving slot 562 a coupling ring 563 and one end in contact with any one of the pair of locking jaws 561, and the other end in contact with the coupling ring 563, and the coupling ring 563 is in contact with the other locking jaw 561. and a return spring 564 that provides an elastic force for pushing it to the side.

When the moving clip 53 moves along the rod 51, the return means 56 made as described above moves while the coupling ring 563 coupled to the moving clip 53 moves while compressing the return spring 564. At the same time as the force pulling the moving clip 53 is released, the coupling ring 563 moves to the original position by the restoring force of the return spring 564 and simultaneously moves the moving clip 53 . At this time, the movement of the moving clip 53 is limited by the return spring 564 on one side and on the other side of the pair of locking jaws 561 on the other locking jaw 561 on which the return spring 564 is not disposed. limited by

The auxiliary blade 54 is formed in the form of a bar extending in the longitudinal direction, and one end is rotatably disposed on the movable clip 53 and the other end is rotatably disposed on the mixing blade 52 .

These auxiliary blades 54 are arranged to correspond one-to-one with the mixing blade 52 and expand the mixing blade 52 while being deployed according to the position of the moving clip 53, and the mixing blade 52 while being assembled in reverse. assemble

That is, when the moving clip 53 is moved to one side by operating the manipulation handle 55 , the auxiliary blade 54 disposed between the moving clip 53 and the mixing blade 52 is deployed while the mixing blade 52 is also develop

Then, while the moving clip 53 is returned to its original position, the auxiliary blade 54 is also assembled while the mixing blade 52 supported is also assembled so as to be close to each other.

The manipulation handle 55 is disposed at the other end in the longitudinal direction of the rod 51 and the wire 514 is coupled thereto. By moving the manipulation handle 55, the wire is pulled or moved to the original position to make the auxiliary blade 54. and the mixing blade 52 is deployed or assembled.

The mixing module 50 configured as described above operates the manipulation handle 55 to pull the moving clip 53 to deploy the auxiliary blade 54 and the mixing blade 52 to mix the materials put into the preheating box 21 . and the auxiliary blade 54 and the mixing blade 52 are assembled in the process of being put into or separated from the preheating box 21 so that the tower entrance 211 of the preheating box 21 can be entered and exited.

As described above, in the present invention, specific matters such as specific components, etc., and limited embodiments and drawings have been described, but these are only provided to help a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , various modifications and variations are possible from these descriptions by those of ordinary skill in the art to which the present invention pertains.

Therefore, the spirit of the present invention should not be limited to the described embodiments, and not only the claims to be described later, but also all those with equivalent or equivalent modifications to the claims will be said to belong to the scope of the spirit of the present invention. .
