Problems solved by technology

Therefore, the production environment and product inspection of the light guide plate are very strict. After the light guide plate is produced, it needs to be inspected to check whether there are scratches, white spots, oil stains and other defects on the light guide plate. In the past, manual inspection was used. However, due to the slow efficiency of manual inspection and the poor quality of inspection, it needs to be carried out in a high-brightness environment during manual inspection, which is harmful to people's eyesight, and the light guide plate is easy to cause secondary pollution due to environmental factors.

Abstract

The invention discloses a light guide plate detection machine. The light guide plate detection machine comprises a workbench, an outer cover, a computer, an NG product collection box, an FFU fan, an ion fan and a laminating device. The laminating device is arranged on the workbench and comprises a good product film laminating machine and a defective product film laminating machine; and the light guide plate detection machine further comprises a feeding mechanism, a material taking mechanism and a detection mechanism which are arranged on the workbench. A light guide plate is fed in the feedingmechanism, the material taking mechanism transfers the light guide plate into the detection mechanism, and a visual camera in the detection mechanism collects images of the light guide plate and sends the images to the computer for analysis; the material taking mechanism transfers the light guide plate according to a computer analysis result; if the analysis result is passed, the material takingmechanism transfers the light guide plate to the good product film laminating machine for film laminating, or else, the material taking mechanism transfers the light guide plate to the defective product film laminating machine for film laminating or to the NG product collection box for collection. Compared with a previous manual detection mode, the light guide plate detection device has the advantages that the detection efficiency is high, and secondary pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a light guide plate detection machine. Background technique [0002] The design principle of the light guide plate is derived from the liquid crystal display of the notebook computer, and it is a product that transforms the line light source into a surface light source. Using PMMA and PC as the base material, using the backlight module technology of LCD display and notebook computer, through the high light conductivity of the light guide point, the light guide point is calculated by the computer, so that the light of the light guide plate is refracted into a surface light source with uniform light State Manufacturing Molding. The product adopts the principle of spectral analysis combined with digital UV printing technology and is produced under constant temperature, constant humidity and dust-free environmental conditions. Therefore, the production environment and p...
