Abstract

The invention relates to the technical field of liquid crystal panel production, and discloses substrate glass light transmittance detection equipment and a substrate glass preparation process. The substrate glass light transmittance detection equipment comprises an electric sliding rail, a differential mechanism, a hydraulic machine, a light emitter, a light receiver and an air compressor, a detection support is arranged above the electric sliding rail, and two telescopic lifting rods are arranged on the detection support in a lifting mode; hydraulic machines are arranged at the top ends of the telescopic lifting rods, detector mounting blocks are arranged at the bottom ends of the telescopic lifting rods, and a light emitter and a light receiver are arranged at the bottom ends of the two telescopic lifting rods correspondingly. The two telescopic lifting rods which are correspondingly arranged and can slide in the annular grooves are arranged, the two driving cross rods are driven by the driving shafts to synchronously rotate, the driving cross rods synchronously rotate and are transmitted to the two telescopic lifting rods through the connecting rings to enable the two telescopic lifting rods to synchronously rotate, and then the included angles between the two telescopic lifting rods and the glass substrate can be adjusted; and therefore, the light transmittance of different angles of each point in the same column position can be further detected.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel production, in particular to a substrate glass light transmittance detection device and a substrate glass preparation process. Background technique [0002] The glass substrate is a basic component that constitutes a liquid crystal display device. This is a thin glass sheet produced by the float process with an extremely flat surface. There are three main process technologies for producing glass substrates for flat panel displays, which are float method, orifice downdraw method and overflow fusion method. During a series of operations such as forming, cutting, grinding, and manipulating the glass substrate, foreign matter such as air bubbles, impurities, or stones may be mixed in due to various factors, which may cause stains, scratches, cuts, or cracks on the glass substrate. Multiple flaws. In addition, during the product manufacturing process, various processing will be performe...
