Detection method for checking correctness of mounting of lens of polarization glasses

Abstract

The invention discloses a detection method for checking correctness of mounting of a lens of polarization glasses. The detection method comprises the following steps of: emitting detection white light through an LED (Light Emitting Diode) lamp emitting source, wherein the detection white light passes through a reference polarizer and detected three-dimensional glasses lenses to obtain a transmittance value for the white light to pass through overlapped lenses; transmitting the value to a read-out, determination and display device in a wired way; comparing, by the read-out, determination and display device, the signal with an internally set standard value of the read-out, determination and display device; producing two determination results, a correct result and a wrong result, by determining whether the transmittance value falls in the internally set standard value range; and digitalizing the two determination results and then displaying on a display screen of the read-out and determination device. According to the detection method, the change from manual detection into equipment detection can be realized by the polarization glasses, so that the phenomena of wrong detection and detection omission produced by personal factor influence and the defect of incapability of detection by manual detection can be completely avoided; and the detection method is a great progress in the quality check method of the three-dimensional glasses products, and has great social significance and market prospect.

Description

technical field [0001] A detection method for checking whether the lenses of polarized glasses are installed correctly. Background technique [0002] Polarized glasses consist of two lenses with different polarization directions. If the lens is missing from the glasses or the polarization direction of the left and right lenses is reversed, it will cause the consequences that the glasses cannot be used. [0003] In the past, the detection of whether the lens of polarized glasses was missing and whether the direction of polarization was reversed was manually detected. Manual inspection, although the technical operation of the above two inspection items can be effectively realized, but due to fatigue, energy distraction, interference from external factors and other reasons, the inspectors will cause misoperation, and the above phenomenon cannot be completely eliminated during the production of polarized glasses. ;At the same time, during manual inspection, due to the manu...

Problems solved by technology

Manual inspection, although the technical operation of the above two inspection items can be effectively realized, but due to fatigue, energy distraction, interference from external factors and other reasons, the inspectors will cause misoperation, and the above phenomenon cannot be completely eliminated during the production of polarized glasses. ;At the same time, during manual inspection, due to the manual operation of the spectacles, some problems cannot be effectively detected due to the different angles of the hand-held spectacles, resulting in the occurrence of false detection and missed detection; moreover, for lens production , Due to the angle deviation of the polarized light absorption axis caused by the wrong lens cutting, the human naked eye cannot directly detect it. In summary, the above problems make it impossible to detect the glasses with the above product quality problems by manual inspection methods
