Diffusion barrier printing processingequipment based on image location

Technical Field

The utility model relates to a diffusion barrier printing processingequipment based on image location.

Background

The optical diffusion film is widely applied to devices requiring light sources, such as liquid crystal displays, advertising light boxes, lighting lamps and the like, and particularly in the liquid crystal display devices, the diffusion film is a key part in a backlight module. The optical diffusion film is mainly used for improving the light brightness, softly diffusing the light received by the light guide plate, providing an even surface light source for the display and playing a role in widening the visual angle. The diffusion film is used for uniformly converting a linear light source or a point light source into a surface light source, and the function principle of the diffusion film is that light passes through media with different refractive indexes, and the light generates a plurality of refraction, reflection and scattering phenomena to cause an optical diffusion effect.

The diffusion film is usually manufactured by a scattering particle type wet coating method, and the conventional diffusion film has a structure including a diffusion layer, a base material, and anti-blocking particles from top to bottom, the diffusion layer including scattering particles (also referred to as diffusion particles or diffusion particles) and a binder resin. The substrate is usually a transparent optical-grade polyester film, and the scattering particles may be inorganic particles or polymer particles (or polymer particles). The upper layer and the lower layer of some diffusion film structures are diffusion layers, and the lower diffusion layer of some diffusion films is provided with an adhesive layer. The diffusion layer is formed by coating a mixture of scattering particles and a binder resin, such as polyacrylic resin (or acryl resin), on the surface of a substrate, and drying the coating at a high temperature to remove a solvent and then hardening the coating.

However, most of the existing devices adopt a separation type processing method, the base material is firstly printed and coated and then dried, the product after drying is rolled, and then the rolled continuous diffusion membrane is cut and then cleaned to finish the product. So processing not only causes the production line to be elongated, and area is big, can't just accomplish the production of deciding the specification diaphragm in a production moreover, and product quality receives the foreign matter influence in the external environment easily, and the product yields can be influenced greatly in the foreign matter attached to the diffusion barrier surface.
