Problems solved by technology

The method of saw blade cutting edge material has the following disadvantages: on the one hand, the incision of the saw blade is wider, and the utilization rate of the product is reduced; In the later stage, it is necessary to clean up the powder dust falling on the surface of the light diffusion plate
Secondly, the removed side material needs special operators to collect and process, which wastes manpower and material resources

Abstract

The invention discloses an automatic separation method of a cut edge material of an optical diffusion plate. The automatic separation method comprises the specific implementation steps of partial cutting procedure, cooling conveying procedure, traction rolling procedure and edge material automatic separation procedure, wherein the edge material of the optical diffusion plate is subjected to non-penetrating partial cutting through an edge cutting device; a notch between the edge material and an optical diffusion plate body is subjected to depth extension during follow-up cooling and rolling; and the edge material and the optical diffusion plate body are automatically separated through an automatic separation device. The automatic separation device comprises a supporting cross rod and separation rods, wherein one separation rod is fixed to each of length ends of the supporting cross rod through welding; the distance between the outer sides of the two separation rods is equal to the widthdimension of the optical diffusion plate body; and the separation rods right face the notch of the optical diffusion plate. According to the automatic separation method and the automatic separation device, through the cutting mode, the notch width is decreased, sawing dust is avoided, the material utilization rate is increased, cleanliness of the optical diffusion plate is guaranteed while the working environment of a workshop is improved, input of manpower and material resources is reduced, and production cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of mechanical equipment, and specifically relates to an automatic separation method and an automatic separation device for edge trimming of a light diffusion plate. Background technique [0002] The light diffusion plate uses chemical or physical means to use the physical imagination of refraction, reflection and scattering when light encounters two media with different refractive indices on the way. Inorganic or organic light diffusing agents are added to the foundation, or the light is artificially adjusted through the array arrangement of the micro-feature structure on the surface of the substrate, so that the light can be refracted, reflected, and scattered in different directions, thereby changing the path of the light and realizing the full intensity of the incident light. Scattering is used to produce the effect of optical diffusion. Light diffusion plates are widely used in liquid crystal dis...
