Optical filter test equipment and test method

Abstract

The invention discloses optical filter test equipment and test method, and aims to provide optical filter test equipment and test method with high automation. The optical filter test equipment comprises a bottom plate, wherein a robot loading and unloading mechanism, a unloading mechanism, a loading mechanism, a lower film surface detection mechanism and a plurality of coupling test mechanisms arearranged on the bottom plate, the unloading mechanism, the loading mechanism and the lower film surface detection mechanism are sequentially arranged in front of the robot loading and unloading mechanism from left to right, the plurality of coupling test mechanisms are sequentially arranged at one side of the robot loading and unloading mechanism from top to bottom, and an upper film surface detection mechanism is arranged on the robot loading and unloading mechanism in a matching way. The optical filter test equipment is applied to the technical field of optical test.

Description

technical field [0001] The invention relates to a test device, in particular to a filter test device and a test method thereof. Background technique [0002] Present smart phone all has camera, and camera front end is provided with optical filter. Filters can eliminate unnecessary light from CCD or CMOS sensing to ensure the best RGB three-color imaging. Filters are widely used in mobile phone cameras, robots, industrial equipment, vehicle systems, digital cameras, digital cameras, computer cameras, mesh, security monitors, video phones, video doorbells, 5G optical communication wavelength division multiplexing, etc. very broad. In the production process of the optical filter, in order to ensure the quality of the ex-factory products, it is necessary to carry out loading and unloading operations, appearance defect detection and photoelectric coupling test for each optical filter, so as to eliminate the defective products, and the existing optical filter The test equipment...

AI Technical Summary

Problems solved by technology

In the production process of optical filters, in order to ensure the quality of ex-factory products, it is necessary to carry out loading and unloading operations, appearance defect detection and photoelectric coupling testing for each optical filter, so as to eliminate defective products. The test equipment has a low degree of automation, which leads to low production efficiency of the filter; in addition, the existing filter test equipment, in the process of photoelectric coupling testing of the filter, places the filter The position of the test platform is mostly adjusted manually, which is obviously prone to adjustment errors and affects the test accuracy
