Problems solved by technology

The traditional light diffusion plate production process has a low degree of automation and mainly relies on manual operations. Among them, the processes of weighing, handling, slicing, and stacking of the light diffusion plate need to be completed manually. Not only the production and processing efficiency is low, but also it relies too much on the operator It is difficult to guarantee the quality of the light diffusion plate because of the professional quality level; because the room temperature difference required by the adjacent processes of the light diffusion plate is relatively large, the distance between the processes can meet the requirements of the working temperature, which again intensifies the difficulty of realizing the automatic production of the light diffusion plate. difficulty

Abstract

The invention discloses an automatic production process of a light diffusion plate. The process specifically comprises the working procedures of material proportioning, material extruding, forming andknurling, edge cutting, transversely cutting, grabbing, stacking, CNC cutting, plate separating, dust removing, CCD detecting, stacking and packaging, heat shrinkage, weighing detecting, automatic labeling, terminal stacking and the like. The wording procedures with relatively large working temperature difference are arranged in independent small workshops connected by conveying grinding rollerscorrespondingly so that flexible control over the temperature can be realized with low cost, and meanwhile, the working procedures for generating debris and noise pollution are controlled within a relatively small range. According to the process, the automatic production process of the light diffusion plate is realized through the arrangement of an automatic conveying device and the correspondingequipment in each procedure, the investment of human capital is reduced, the production period is accelerated, the production cost is reduced, and the production quality is improved.

Description

technical field [0001] The present invention relates to the field of light diffusion plate production, specifically an automatic production process for light diffusion plates. Background technique [0002] In actual production, many plate-shaped products with relatively flat surfaces and certain elastic deformations will be involved. Take the light diffusion plate as an example. When different media are used, the physical imagination of refraction, reflection and scattering occurs, by adding inorganic or organic light diffusing agents to the substrate bases such as PMMA, PC, PS, PP, or artificially through the array arrangement of micro-feature structures on the surface of the substrate. Adjust the light to make the light refract, reflect, and scatter in different directions, thereby changing the path of light, and achieving sufficient dispersion of incident light to produce the effect of optical diffusion. The light diffusion plate is widely used in liquid crystal display,...
