Chromaticity detector for light source of vehicle lamp

Abstract

The invention discloses a chromaticity detector for a light source of a vehicle lamp, comprising a frame, a pneumatic fixture, a dark room, a camera, a signal indicating alarm device, a control keyboard, a control box, an image display screen, an air pressure meter, a handle, a first fixing block, a lifting door and a picking and placing opening. The frame is provided with a pneumatic clamp on thebottom surface, and is provided with the control box, which is provided with the display screen, the control keyboard, the air pressure meter and the signal indicating alarm device on the front end face; the picking and placing opening is formed in the side surface of the frame, the first fixing block is fixedly arranged on the side wall of the frame above the picking and placing opening, and isvertically and slidably provided with the lifting door inside. According to the chromaticity detector for the light source of the vehicle lamp, visual damage caused by manual visual inspection can bereduced, detection precision is improved, and detection false and detection miss caused by human causes are avoided; cost increase caused by new equipment invested is greatly reduced; efficiency is obviously improved than a spectrum detection method, occupied area of whole equipment is small, so that the method is suitable for a situation that the production site is cramped.

Description

technical field [0001] The invention relates to a detection device, in particular to a vehicle light source chromaticity detection machine. Background technique [0002] Colorimetry is a comprehensive science based on the subject areas of physical optics, visual psychology and psychophysics. Color measurement and evaluation technology in colorimetry is a commonly used detection method in physics, analytical chemistry and biochemistry. There are generally two methods for existing chromaticity detection methods, one is visual detection method, which relies on human eye recognition, poor accuracy, and long-term operation will cause damage to vision. The other is the spectral radiation detection method, whose detection principle is to capture the light source image of the car light through a color camera, and convert the image into three-color components of R (red), G (green), and B (blue) (gray of 0 to 255). color scale value), calculate the ratio of each component to the tot...

There are generally two methods for existing chromaticity detection methods, one is visual detection method, this detection method relies on human eye recognition, the accuracy is poor, and long-term operation will cause damage to vision

The other is the spectral radiation detection method, whose detection principle is to capture the light source image of the car light through a color camera, and convert the image into three-color components of R (red), G (green), and B (blue) (gray of 0 to 255). color scale value), calculate the ratio of each component to the total, and the formulas are: R value ratio=R / (R+G+B=0.001); G value ratio=G / (R+G+B =0.001); B value ratio = B / (R+G+B=0.001); determine whether the color of the lamp is normal by limiting the upper and lower limits of the ratio of each component, but this method has high equipment costs and requires replacement of the detected object And light source switching is cumbersome, not suitable for mass production
