Abstract

The invention discloses a light guide plate verification device. The device comprises four laser modules, a laser emitter and four CCD image sensors, wherein two laser modules are fixed on a slide onone side of a laser platform through sliding blocks; the other two laser modules are fixed on a slide at the other side of the laser platform; laser beams emitted by the laser emitter are input to reflectors of the laser modules through transmission light paths and then input onto a light guide plate through beam splitters and focusing mirrors of lens cones of the reflectors; the four CCD image sensors are respectively mounted below the four lens cones and synchronously move along with the lens cones; in a processing of forming lattice points on the surface of the light guide plate, the CCD image sensors sense each lattice point in real time, record the lattice point distribution and lattice point regularity and transmit lattice point states to an upper computer, so as to form lattice point images in the upper computer.

Description

technical field [0001] The invention relates to the technical field of light guide plate manufacturing, in particular to a light guide plate inspection device and method. Background technique [0002] At present, the development trend of the TV display industry presents the characteristics of large size, thinness, low power consumption, high color gamut, and high brightness, while the laser dot light guide plate has ultra-thin, high brightness, uniform light guide, short development cycle, energy saving, and environmental protection. , no dark area, durable, not easy to yellow, low defect rate and other remarkable features, so it can meet the current development needs of the display industry. [0003] However, at present, the production efficiency of laser light guide plates is lower than that of printing, and a large amount of manpower is required to inspect macroscopic images, which consumes a lot of manpower, material resources, and financial resources. [0004] How to p...
