A device for detecting sag of a glass substrate

Abstract

The invention discloses a device for detecting a sunken flaw of a glass substrate. The device comprises a protecting bin, support shells and a support plate; the left and right ends of the support plate are connected with the support shells; the protecting bin is arranged on the surface on the left side of the support shell on the left end; a hinge is connected with the surface on the left side ofthe support shell on the left end; a mechanical arm is in rotary connection with the hinge; a light source a is connected with the mechanical arm; when the glass substrate needs to be detected, the glass substrate is clamped by adjusting the positions between the connecting plate and the connecting plate by rotating a handle a, the light source a is adjusted to be parallel to the glass substrate,and the light projected from the light source a passes by the glass substrate and then is projected onto a probe of a camera device; when the sunken flaw is detected on the glass substrate, an obvious difference can be captured by the camera device due to the reflection relation of light, and a light spot can be formed by the light source on a light-transmitting plate on the sunken position of the glass substrate. The device has a simple structure, convenience in operation and capability of effectively detecting the glass substrate.

Description

technical field [0001] The invention relates to the field of glass substrate detection, in particular to a device for detecting glass substrate depressions. Background technique [0002] Glass substrate is one of the key basic materials of the flat panel display industry. Although this component only accounts for 17% of the total cost of the LCD panel, it is the most delicate and the transportation cost is very high, and its output directly affects the color filter above the 5th generation line The output of parts and components is the most critical part of panel production. [0003] During the production of glass substrates, actions such as cutting, handling, and clamping of the glass will also cause defects such as scratches on the glass surface. All of these will have a non-negligible impact on the light transmittance and processing performance of the glass. Manufacturers need to select and process damaged glass substrates. Therefore, those skilled in the art provide a d...
