A method and device for rapid positioning and detection of automobile headlights

Abstract

The invention discloses a method and device for rapid positioning and detection of automobile headlights, which include a positioning plate, a transmission assembly, a headlight detector, an induction assembly, a horizontal positioning assembly and an automobile straightening assembly. The transmission assembly includes a sliding base and a pillar 1. The first photosensitive assembly and the axis guide rail assembly, one side of the positioning plate is fixed with the X-axis guide rail assembly, the sliding base is slidably arranged on the X-axis guide rail assembly, and a pillar is vertically fixed on the sliding base, and one side of the pillar is vertically arranged There is a Z-axis guide rail, on which the headlight detector is slidably arranged, the front end of the pillar is provided with a first photosensitive assembly, and the front of the transmission assembly is sequentially provided with an induction assembly, a horizontal positioning assembly and an automobile straightening assembly. The approximate range of the headlight on the X-axis and the Z-axis is respectively determined by the horizontal positioning component and the first photosensitive component, thereby greatly reducing the moving range of the headlight detector and making the positioning of the headlight faster.

Description

technical field [0001] The invention relates to the field of positioning and detection of automobile headlights, in particular to a method and device for rapid positioning and detection of automobile headlights. Background technique [0002] The vehicle headlight tester is used to detect the luminous intensity and optical axis offset of the car headlights. It is suitable for motor vehicle inspection stations, automobile manufacturers, auto repair shops, supporting 4S shops, and agricultural machinery supervision departments for tractors and automobiles. Check and adjust the headlights. In recent years, various types of vehicle headlight detectors have appeared on the market. As a detector, whether the test results can accurately reflect the actual beam intensity of vehicle headlights is a difficult point. The main factors are: when testing vehicles For headlights, the center of the detector body should be facing the strongest beam area of ​​the current vehicle headlights. ...

AI Technical Summary

Problems solved by technology

Although this method solves the shortcomings of the manual headlight detector, it cannot determine the approximate position of the headlight because the vehicle enters from different positions, so the detector body is required to judge the strongest light area, because the detector The light-receiving area of ​​the main body is limited, and it is necessary to move the light box back and forth several times in the horizontal direction and move up and down in the vertical direction to track and locate the strongest light area. Therefore, the software processes a large amount of data, takes a long time to detect, and often misses the light intensity. The highest position, resulting in positioning failure

[0004] At the same time, when the vehicle is driving in, the vehicle body is usually not straightened, causing the position of the headlights to deviate, which seriously affects the detection results
