Problems solved by technology

[0004] However, since the mold is composed of multiple independent sub-molds, each sub-mold is processed independently and used in splicing, so when producing Fresnel lens arrays in large quantities, problems of low processing efficiency and high processing cost often occur

Abstract

The invention discloses roller mould machining equipment for a polygonal Fresnel lens array. The equipment comprises a gas flotation spindle, an A-axis base, X-axis guide rails and Z-axis guide rails,wherein the gas flotation spindle is used for controlling a roller to rotate around the Z-axis when the central axis of the roller coincides with the Z axis; a tool used for cutting the roller is arranged on the A-axis base; and the X-axis guide rails are used for controlling the A-axis base to move in the direction perpendicular to the Z-axis, and the X-axis guide rails are mounted on the Z-axisguide rails and can move along the Z-axis guide rails. According to the machining equipment provided by the invention, through all-axes linkage, an intact mould structure corresponding to the polygonal Fresnel lens array is machined in the surface of the roller, by means of a roller mould pressing technology, a large batch of polygonal Fresnel lenses can be manufactured continuously on optical thin film, and the overall optical performance, the production efficiency and the machining precision of the Fresnel lenses are improved.

Description

technical field [0001] The invention relates to the technical field of part processing, in particular to a processing equipment for a roller mold polygonal Fresnel lens array. Background technique [0002] Fresnel lens is an important diffractive element, which has a wide range of applications in many fields due to its light weight, small size and excellent optical performance. The Fresnel lens array specifically refers to an optical element composed of multiple Fresnel lenses. The main measure of its optical performance is the filling factor, that is, the percentage of the lens area to the total area. The higher the ratio, the better the optical performance. the better. For this reason, the current Fresnel lens arrays have been developed into different shapes, most of which are formed by arranging multiple Fresnel lenses trimmed into rectangular or hexagonal layouts. [0003] In the actual production process, it is necessary to use the mold to make the Fresnel lens array....
