Description

Feed roller device for plate-like feed {TRANSFER ROLLER APPARATUS FOR PLATE-TYPE COMPONENTS}

The present invention relates to a transfer roller device for transferring plate parts such as glass for solar cells, smartphones, or semiconductors, and more particularly, to prevent breakage, distortion, and sagging of the rotating shaft, thereby improving the transfer efficiency and reliability of the device. The present invention relates to a plate-type component conveying roller device capable of improving the product yield by improving the product capacity by easily and simply expanding the facility while maintaining the existing facility, and preventing scratches and slips on the conveyed material.

In general, a liquid crystal display (LCD) glass manufacturing process uses a conveying device for conveying glass. The conveyed material conveyed by such a conveying device includes the aforementioned LCD glass, a flat panel display (FPD), a solar cell, and the like. An optical panel and other flat conveyances may be included, but for the sake of convenience, hereinafter, "LCD glass" will be described as an example of the object to be transported.

As is well known, an LCD injects a liquid crystal, which is an intermediate of a solid and a liquid, between two thin upper and lower glass substrates, and changes the arrangement of liquid crystal molecules by an electrode voltage difference between the upper and lower glass substrates (hereinafter referred to as "LCD glass"). It is a device using a kind of optical switch phenomenon that generates a contrast and displays a number or an image.

Currently, these LCD technologies are widely used in electronic clocks, electronic devices such as electronic calculators, TVs, notebook PCs, speed displays and driving systems of automobiles and aircrafts.

In particular, LCD TVs and monitors using the LCD technology have been mainstream in sizes of 20 to 30 inches and 17 inches, respectively, but recently, preference for large LCD TVs of 40 inches or more and large monitors of 20 inches or more is increasing. Therefore, manufacturers of LCDs have come to produce wider LCD glass.

On the other hand, such LCD glass has brittleness which is very vulnerable to the impact applied from the outside. Therefore, if the LCD glass can be efficiently stored and transported from the pre-process step to the post-process step of manufacturing the LCD glass without being damaged, it will not only improve productivity but also maintain the flat display quality. Definitely

In particular, as described above, as the size of the LCD glass, which is enlarged as in the recent trend, becomes larger in size and thinner, special care is required in storing and transporting the LCD glass.

In order to transfer the LCD glass, a conveying apparatus using a roller capable of conveying the LCD glass more safely and quickly is used.
