A mold for manufacturing cylindrical mirror array

Abstract

The present invention provides a mold for manufacturing a cylindrical lens array, comprising: a male mold assembly, a female mold assembly and a runner assembly, wherein the female mold assembly includes a box body, and the bottom surface of the box body presents Out of the envelope in the shape of a cylindrical mirror, the male mold assembly includes a flat plate as the upper cover plate of the box body, the flat plate is matched with the box body and is tightly combined at the edge; the flow channel assembly is One side of the box body is connected, and the raw material is injected into the box body through the flow channel assembly. The mold for manufacturing the cylindrical lens array of the present invention is used when high-light-transmitting PC material or PMMA material is used instead of glass material to manufacture the cylindrical lens array, which can reduce the process links of cylindrical lens processing and achieve better optical quality. Performance indicators, reduce costs, suitable for mass production.

Description

technical field [0001] The invention relates to the technical field of PTN networks, in particular to a mold for manufacturing cylindrical mirror arrays. Background technique [0002] In optical system design, aspheric optical parts can obtain better imaging quality than spherical optical parts. At the same time, using one or several aspheric parts instead of multiple spherical parts can simplify the component structure in the optical system. , effectively reduce the quality of components, and correct a variety of imaging deviations, improve imaging quality, and improve the performance of the optical system. [0003] Cylindrical lens is a common aspheric optical element. Its main function is that when a parallel light beam passes through the cylindrical lens, it can make the focal point be drawn into a line along one direction. It is widely used in various optical systems; it is composed of multiple The form of cylindrical mirrors forming an array is also widely used. Becau...

AI Technical Summary

Problems solved by technology

[0005] 1) The process is complicated, there are many processing links, time-consuming and labor-intensive, and the cost is high

[0006] Glass cylindrical mirror arrays cannot be produced through moulds, and multiple cylindrical mirrors need to be processed and bonded separately. The main processes include cutting, rough grinding, fine grinding, polishing, precise measurement, bonding, etc., which is not conducive to mass production. Production, many process links cause high cost

[0007] 2) The bonding link is difficult to control and the defective rate is high

[0008] The cylindrical mirror array made of glass is composed of multiple single cylindrical mirrors bonded together. Before bonding, the single cylindrical mirrors need to be precisely measured, otherwise there will be defective products caused by insufficient processing precision of the single cylindrical mirrors; In the bonding process of the measured single cylindrical mirror, it is easy to have defective products caused by adhesive bubbles
