Light source module, and float glass online defect detection device and method

Abstract

The present invention discloses a light source module, and a float glass online defect detection device and method. The light source module comprises a transmission light source sub-module, the transmission light source sub-module comprises a stripe light source, core light sources and a light splitting assembly, and the light splitting assembly comprises a spectroscope and a first convex lens; the plane of the first convex lens faces the spectroscope and forms an angle of 45 DEG with the spectroscope; the stripe light source is arranged on the side, deviating from the first convex lens, of the spectroscope, and the projection direction of the stripe light source is perpendicular to the plane of the first convex lens; and the core light sources are arranged on the side, facing the first convex lens, of the spectroscope, the projection direction of the core light sources is parallel to the plane of the first convex lens, and the core light sources are sequentially arranged in multiple rows side by side in the direction from far to near away from the first convex lens. Online high-precision conventional defect detection and measurement of weak deformation defects such as high-precision glass ribs can be realized at the same time.

Description

technical field [0001] The invention belongs to the technical field of machine vision, and in particular relates to a light source module, an online defect detection device for float glass and a detection method thereof. Background technique [0002] The production and molding process of float glass is completed in a tin bath filled with protective gas (N2 and H2). The molten glass flows continuously from the tank kiln and floats on the surface of the relatively high-density molten tin. Under the action of gravity and surface tension, the molten glass is spread and flattened on the surface of the molten tin to form flat upper and lower surfaces and harden. , After cooling, it is led to the transition roller table. The rollers of the roller table rotate, and the glass ribbon is pulled out of the tin bath and enters the annealing kiln. After annealing and cutting, the float glass product is obtained. Compared with other forming methods, the float method has the following adv...
