Electric dimming device and headlight online detection system

Abstract

The invention provides an electric diming device. A diming screw arranged in a to-be-detected car lamp arranged at a preset angle position is rotated to adjust the position of a light and shadow dividing line of the to-be-detected car lamp. The electric dimming device is included in a car lamp online detecting system, and receives car lamp in-place signals, dimming starting signals for starting to rotate the dimming screw, forward dimming signals for rotating the dimming screw in the forward direction, reverse dimming signals for rotating the dimming screw reversely and dimming stopping signals for stopping rotating the dimming screw, wherein the car lamp in-place signals are sent when a work position conversion device in the car lamp online detecting system conveys the to-be-detected car lamp to the preset angle position, and the dimming starting signals are sent by a light detecting device in the car lamp online detecting system. The electric diming device is characterized in that a dimming unit, an input setting unit, a locating unit, a CAN bus interface and a dimming control unit, wherein the dimming unit comprises a dimming cutter, a dimming motor and a dimming driving portion, and the locating unit comprises a longitudinal locating mechanism, a transverse locating mechanism and an axial locating mechanism.

Description

technical field [0001] The invention relates to an electric dimming device capable of automatic dimming and an on-line detection system for vehicle lamps. Background technique [0002] Along with the raising of economic level, automobile has become the main means of transportation in people's daily life. In order to ensure traffic safety while driving, the light beams emitted by the headlights or fog lights of the car should be as soft as possible, so as to avoid dazzling and other discomfort to the drivers and passengers of other vehicles in front. Therefore, the light and dark cut-off line of car lights The location is important. The national standard GB4599-2007 "Filament Bulb Headlamps for Automobiles" and the national standard GB4660-2007 "Filament Bulb Front Fog Lamps for Automobiles" respectively make specific regulations on the technical indicators of automotive headlights and fog lamps, pointing out the light and dark cut-off line The position can be adjusted with...

Problems solved by technology

Therefore, there are the following problems: on the one hand, the accuracy of manual dimming is low, which seriously affects the light inspection results; on the other hand, it is impossible to realize the full automation of the entire inspection process, which seriously restricts the efficiency of lights

In addition, in order to facilitate manual operation, it is bound to impose certain restrictions on the overall structure of the testing equipment, which may increase the volume of the equipment or affect the overall compactness of the equipment and the fluency of the testing process, which is not suitable for strict requirements on the size of the testing equipment. occasion

[0004] Nowadays, all fields of industrial production are committed to replacing manpower with machinery. Efficient workflow and simple mechanical structure have become the goals pursued by enterprises. CAN bus is widely used for its ease of use, stable communication and flexible configuration. Automotive industry, on-line detection and many other fields, but the technology of applying CAN bus to the on-line detection system of car lights to realize dimming function is still rare. Therefore, a CAN bus-based structure can replace manual operation to realize automatic dimming The electric dimming device and the online detection system of the car lights are particularly important
