Rod lens arraying tool, original plate cutter and cutting method, end face cutting device

Abstract

The invention relates to a method for manufacturing a rod lens array, which includes: a stage for forming an array precursor where at least one rod lens array is temporarily fixed between the 1st and the 2nd base plates, a stage for sealing both side end faces of the precursor in the longitudinal direction of the rod lens with a sealing agent, a stage for supplying an adhesive to one end face of the precursor in the longitudinal direction of the rod lens, decompressing the other end side and filling the precursor with the adhesive so as to obtain a rod lens array original plate, and a stage for forming the rod lens array by cutting the rod lens array original plate in a direction orthogonal to the rod lens after the adhesive is hardened.

Description

[0001] This application is a branch of the application number 200410000459.8 filed by the inventor on January 29, 2004, and the title of the invention is "Manufacturing method of rod lens array, and arrangement jig, original plate cutting device, and end face cutting device" used in the method. case application. technical field [0002] The invention relates to a rod lens array manufacturing tool, cutting and cutting technology. Background technique [0003] As one type of microlens, a cylindrical plastic rod lens in which both end surfaces are mirror-polished is known. Such a plastic rod lens, in addition to being used alone, is also used in copiers, facsimile machines, scanners, portable scanners, etc. Optical elements for image sensors used, or used as writing devices in devices such as LED printers using LEDs (light-emitting diodes) as light sources, liquid crystal printers using liquid crystal elements, and EL printers using EL elements. In recent years, such rod lens...

Problems solved by technology

[0010] However, in the above-mentioned manufacturing method, there is a problem that although a rod lens array suitable for high resolution can be manufactured, the yield is low and the production efficiency is poor.

However, in the mass production process in which cutting is performed continuously, there is a problem that, due to external factors such as thermal expansion, misalignment occurs in the set position, and it is difficult to stably implement high-precision flatness.

[0014] Such problems also occur when processing the end faces of workpieces other than rod lens arrays that require high-precision planar processing.
