Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of light guide plate detection, in particular to a light guide plate ink adhesion detection equipment. BACKGROUND

[0002] A light guide plate is a key optical component, mainly used to achieve efficient diffusion and uniform distribution of light sources. It is usually made of high-transmittance polymer material by injection molding, and specific microstructures (such as dots, prisms or etched lines) are formed on the surface or inside through precision machining. Its working principle is based on the principle of total reflection: when light is incident from the edge or a specific position, it will undergo multiple total reflections in the plate, and when it encounters surface microstructures, it will scatter, thereby converting concentrated linear light sources / point light sources into uniform planar light. Modern light guide plate design often combines diffusion film, brightness enhancement film and other auxiliary optical films to further improve brightness uniformity and light energy utilization. This technology is widely used in liquid crystal display backlight modules, LED panel lights, advertising light boxes, automobile instrument panels and other fields, with the advantages of thin thickness, light weight, flexible bending, etc., and can effectively reduce energy consumption, and is one of the core components of new display and lighting technology.

[0003] During the production process of the light guide plate, the ink adhesion performance needs to be sampled and tested. The ink adhesion problem of the light guide plate may be caused by many factors, including improper treatment of the substrate, ink formula problems or unsuitable process parameters. If the test finds that the adhesion is insufficient, methods such as corona treatment, adding adhesion promoters or adjusting drying parameters can be considered to improve it.

[0004] Nowadays, the detection is usually carried out by scratch resistance test: use the thumb nail to apply moderate pressure and repeatedly scratch the dry ink layer several times to observe whether there are scratches or peeling.

[0005] The traditional scratch resistance test is carried out by manual operation, which has low detection efficiency and causes high labor intensity of workers. At the same time, the heat generated by friction during repeated scratching will cause the detection area to heat up, and high temperature may cause softening and affect the accuracy of the test. Therefore, we propose a light guide plate ink adhesion detection equipment. SUMMARY
