Rapid positioning detection method and device for automobile headlamp

Abstract

The invention discloses a rapid positioning detection method and device for an automobile headlamp. The rapid positioning detection device comprises a positioning plate, a transmission assembly, a headlamp detector, an induction assembly, a horizontal positioning assembly and an automobile correcting assembly. The transmission assembly comprises a sliding base, a supporting column, a first photosensitive assembly and a shaft guide rail assembly. An X-axis guide rail assembly is fixed on one side of the positioning plate; the sliding base is arranged on the X-axis guide rail assembly in a sliding manner; the supporting column is vertically fixed to the sliding base, a Z-axis guide rail is vertically arranged on one side of the supporting column, the headlamp detector is arranged on the Z-axis guide rail in a sliding mode, the first photosensitive assembly is arranged at the front end of the supporting column, and the induction assembly, the horizontal positioning assembly and the automobile correcting assembly are sequentially arranged in front of the transmission assembly. The approximate range of the headlamp on the X axis and the approximate range of the headlamp on the Z axis are determined through the horizontal positioning assembly and the first photosensitive assembly respectively, so that the moving range of the headlamp detector is greatly reduced, and positioning of the headlamp is 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
