Abstract

The present invention relates to an automatic inspection system for glass loading cassettes. The cassettes mentioned above are a moving device by which glasses used for a display device of expensive flat panel display products are moved between manufacturing processes after stored and loaded in multi-stages. Recently, the trend of the flat panel display products tends to high resolution, enlargement, and slimness. According to the properties of the glasses, the glasses are more deflected as being larger and thinner, so it might cause damage to the glasses because the glasses can be crashed into some part of the deformed cassette. The factor is generated in portions where people cannot check with the naked eyes, especially, by the geometrical change of the cassette. To solve the problem, Disclosed is the automatic inspection system for glass loading cassettes to prevent not only economical loss, such as damage to the glasses, production delay, and others, but also various faulty factors since faulty cassettes are not put into the manufacturing processes beforehand.

Description

Automatic Cassette Inspection System for Glass Loading {APPARATUS FOR MEASURING DEFORMATION OF GLASS LOADING CASSETTE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a system for automatically inspecting a glass stacking cassette which is used almost as a necessity in a display (screen) device manufacturing process of an expensive flat panel display product.

Glass is used almost as a necessity in the manufacturing process of display devices for expensive flat panel displays.

In recent years, as the size of glass increases and becomes thinner, the importance of cassette production and management becomes increasingly necessary. In particular, there is a problem that it is difficult to check the geometric deformation of the outer or inner support accessories with the naked eye due to the large size of the cassette.

Conventionally, small and medium sized cassettes are mainly handled, and such an inspection apparatus is absent or the structure is complicated. In addition, a product in which a sensor's ability to detect deformation deteriorates is mainly utilized to generate an error. Briefly, the problem of the conventional inspection apparatus is as follows.

① If there is no large cassette inspection device, if there is a problem without any alternative, pause the production line, remove the cassette, visually inspect the geometric deformation first, and then measure gauges, jigs, or other measurements. The apparatus was used to inspect and repair the entire deformation of the cassette.

② As the inspection was conducted by this method, various losses such as a lot of time and production delay occurred.

③ Even if there is a small and medium cassette inspection device, the structure is complicated and it is difficult to check the deformation, or the rigid structure cannot be secured, causing errors or errors due to vibration and vibration.

④ Also, since there is no device for automatically loading / unloading small and medium cassettes, it is not easy for a person to directly supply a cassette to an inspection area, and there is always a risk of a safety accident.
