Manufacturing method for machine vision filter

Abstract

The invention discloses a manufacturing method for a machine vision filter. The manufacturing method comprises the following steps: A, cutting, i.e., cutting a glass substrate according to the required size of equipment, wherein the adopted glass substrate is a colorless glass substrate; B, cleaning, i.e., placing the cut glass substrate in pure water to soak and performing oscillation cleaning by using ultrasonic wave; C, drying, i.e., drying the cleaned glass substrate by using an air drying method; D, plating a main film, i.e., plating the main film by using an ion beam assisted electron beam evaporation coating technology; E, plating a secondary film, i.e., plating the secondary film on the other face of the glass substrate by using the same process in the step D after plating the main film; and F, post-processing, i.e., grinding the edge of the plated glass substrate by using an inner circle cutting machine. According to the manufacturing method, the cost for manufacturing the machine vision filter is greatly reduced by using a series of scientific manufacturing processes, and the signal-noise ratio of the machine vision filter has reached the level of 1,000:1.

Description

technical field [0001] The invention relates to the technical field of vacuum coating, in particular to a method for manufacturing a machine vision filter. Background technique [0002] Due to the continuous development of optical imaging technology and the continuous improvement of automation requirements for various systems, equipment or instruments, machine vision has emerged as an emerging field, such as in various security monitoring fields based on face recognition, and license plate recognition. Basic intelligent traffic management, intelligent robots based on shape and position measurement, production line quality assurance, high-risk operations and other fields. The machine vision system is characterized by improving the flexibility and automation of production. In some dangerous working environments that are not suitable for manual work or where artificial vision is difficult to meet the requirements, machine vision is often used to replace artificial vision; at t...

AI Technical Summary

Problems solved by technology

In China, the level of coating equipment and coating technology is generally low. Most optical film manufacturers can only produce filters with relatively simple coating layers. There are very few manufacturers that can produce narrow-band filters, and they can only rely on colored glass. As the substrate, the design and plating with fewer film layers are far from the level of foreign countries.
