The present invention relates to a panel sheet manufacturing apparatus and a manufacturing method for manufacturing the sheet used in the LCD backlight unit.

In general, liquid crystal displays (hereinafter referred to as LCDs) used in display devices such as laptops, monitors, and liquid crystal televisions (TVs) can realize light weight, short size, and low power consumption compared to cathode ray tubes (CRTs), which are other image display apparatuses. There is an advantage, the demand is gradually increasing. However, unlike the cathode ray tube, the LCD is not a light emitting device but a light receiving device, and thus requires a backlight unit in addition to the LCD screen.

The backlight unit of the LCD is used as a dimming device to evenly transmit light to the entire panel, and the LCD panel displays an image by constantly adjusting the amount of light transmitted.

In a typical LCD, a backlight unit and a liquid crystal panel are arranged in a frame. A typical backlight unit includes a light source such as a cold cathode fluorescent lamp (CCFL), a light guide plate for scattering and homogenizing light emitted from the light source, and a panel sheet such as a diffusion sheet, a protective sheet, and a prism sheet disposed on the front surface of the light guide plate.

There was a problem such as separation. In addition, as the paper is transported, since the height of the stacked paper stacks is gradually lowered, there is a problem such that the distance between the suction sucker of the transfer device and the stacked paper becomes far and the adsorption is not made accurately.

Needed to be positioned at the location. In addition, it was necessary to maintain the correct position until the paper placed under the cutting mold was cut.

In addition, in the manufacture of a panel sheet having a predetermined size by cutting a sheet of paper by a cutting mold of a panel sheet manufacturing apparatus, a panel sheet cut from a sheet of paper is separated from waste paper, and the waste paper is discarded, and only the panel sheet is collected and packaged and shipped. Will go through. At this time, it was necessary to take out the panel sheet and the waste paper which were located under the cutting mold and cut by this cutting mold from below the cutting mold, and separate the panel sheet and the waste paper.

However, when the operator removes the cut panel sheet and waste paper by hand, it is not preferable because the panel sheet may be contaminated. In addition, even when the cut sheet sheet and the waste paper are separated using a separate device, the panel sheet is not accurately separated from the waste paper, and the waste paper is dragged toward the panel sheet. there was.

Accordingly, in the case of continuously supplying sheet paper and manufacturing a sheet having a predetermined shape by a cutting mold, there is a problem that the sheet is not discharged smoothly, which takes a lot of time and effort to work and deteriorates productivity.
