Description

Technical Field

[0001] This utility model relates to the technical field of light guide plate testing equipment, and in particular to a light guide plate material testing device. Background Technology

[0002] A light guide plate is a high-tech product that uses optical-grade acrylic or PC sheets as the base material. Light guide points are created on the bottom surface using laser engraving and printing techniques. It utilizes the principle that light stays within the sheet, is reflected and diffused through the light guide points, and then emitted from the front after breaking the reflection conditions. This transforms point or line light sources into uniform surface light sources. It can be categorized by shape, dot pattern, light incident method, and forming method into different types such as flat and wedge-shaped plates, printed and non-printed types, side-lit and direct-lit types, injection molded and cut-to-shape types. It features ultra-thinness, ultra-brightness, uniform light guiding, energy saving and environmental protection, no dark areas, durability and resistance to yellowing, easy installation and maintenance, and the ability to be arbitrarily cut and spliced ​​or made into irregular shapes. It is suitable for various light sources. The manufacturing process mainly includes injection molding, photolithography, doping, laser engraving, and sandblasting. It is widely used in LCD display module backlight systems (such as televisions, mobile phones, and tablets), as well as ultra-thin light boxes, advertising billboards, medical imaging, scientific research, and high-standard lighting.

[0003] During the production process of light guide plates, impurities, bubbles, and dark lines may be generated on the plate, affecting the light guiding performance. Therefore, after the light guide plate is processed, an inspection process is required. Existing inspection equipment generally uses industrial cameras to directly take pictures and compare, and stops and alarms when defects are found. Manual assistance is needed to confirm the location of the defects before restarting manually. This not only consumes a lot of manpower, but also affects the inspection efficiency due to the interruption. There is room for further improvement. Utility Model Content
