Description

Glass Transfer Device {CARRYING APPARATUS OF GLASS}

The present invention relates to a glass conveying apparatus, and more particularly, because both sides of the glass are fixed by the gripper, the glass can be prevented from falling down even when transporting a large glass. The present invention relates to a glass conveying apparatus capable of inspecting defects of the glass more accurately by preventing the shaking of the conveyed glass by conveying both sides of the glass at the same speed since the conveying is performed by one linear motor.

In general, in-line FPD automatic optical inspection uses an optical lens and a CCD camera while guiding a display panel (hereinafter referred to as “glass”) such as a TFT LCD panel, a PDP, and a color filter. It is a device that detects various defects that a user wants to find by applying a vision image processing algorithm after capturing an image of glass. The inline inspection equipment is largely divided into a scan section, a review section and an unload section to detect a defect. In order for such inspection equipment to function as an inspection system, it is important to accurately locate and size the detected defect. Then, the repair process can be performed to find and repair the detected defect, and even if it is detected as a defect, the defect whose size is small enough to not affect the performance of the FPD circuit can be ignored.

The inline inspection equipment is provided with a conveying device for conveying the glass from the scan section to the review section and from the review section to the unloading section.

In the glass conveying apparatus, as shown in FIG. 1, one side of the glass 10 is fixed by the gripper 20, and the gripper 20 uses driving means such as a motor 30 and a rail 40. The glass 10 is transferred to the next section. However, in the conventional glass transfer apparatus, only one side of the glass 10 is fixed by the gripper 20 to transfer the glass 10, and thus, in the case of the glass 10 having a large area, the glass transfer apparatus is not fixed by the gripper 20. There is a problem that the other side of the glass 10 is not sag to the bottom, the glass 10 is broken or the glass 10 is not smoothly transferred.

In order to solve the above problem, as shown in Figure 2, another glass transport apparatus has been proposed.

The above-described glass transfer apparatus of the other method is provided by the gripper 50 is installed in the lower portion of the center of the glass 10 to support and fix the glass 10, and to transfer the gripper 50 by a driving means such as a motor 60, etc. The glass 10 is transferred to the next section. Then, the air plate 70 for injecting air to the upper portion of the lower portion of the glass 10 is installed to raise the glass 10 to the upper portion. In the above-described glass conveying apparatus, the glass 10 is prevented from being lowered by the gripper 50 and the air plate 70 installed at the center of the glass 10, but the gripper 50 is formed by the glass 10. Since it is located in the center, there was a big problem that can not partially inspect the center of the glass (10).
